 With the development of society, buildings and roads are the cornerstone of the development of human society. People will choose to lay waterproof materials during waterproof maintenance, but people face some problems when laying waterproof materials. When laying waterproof materials, people inadvertently trample on the materials because they do not know that the materials have been laid, resulting in uneven laying of materials and economic losses. Therefore, we need to protect the sites under construction and just completed construction when laying. Many of the existing protective devices are large, which is not conducive to people's carrying, and the protective devices can't be seen by people at night, causing people's damage. The laying of water-proof materials is wasted, and the placement of protective devices is unbalanced, causing collapse and damage to people.   The utility model relates to a wet laying waterproof coiled material construction protective device equipped with a power spring, which can solve the above problems. The power spring requires a housing to limit its outside diameter. The spring stores force during the rotation of the power spring relative to the central axis of the spring housing. When the force disappears, the power spring will produce a torque on the central shaft of the spring housing.   The protective device comprises two expansion columns 1, a contraction device 21, a second fixing block 4 and two expansion columns 1, one of which is provided with a contraction device 21. The retracting device 21 is composed of two rotating discs 12, the first fixed column 13 and the power spring 14. The rotating disc 12 is installed in the...

 A constant torque spring motor is a strip of prestressed spring material that forms a coil and is stored on a small storage drum. The free end is then pinned and rewound onto the larger output drum; this is the "winding" part of the constant torque spring cycle. When the output drum is released, the spring will return to the storage drum to assume its natural curvature, rotating the output drum and providing an almost constant torque.        Constant torque springs are made of type 301 high quality stainless steel and are supplied in coil form for mounting on the motor drum. Its main features are: 1. Long time deflection under almost constant torque. Positive or limited negative gradients can be achieved. 2. Minimal inter-coil friction and resulting hysteresis, which is common in power springs. 3. Rotary motion is provided directly from the output drum or linear displacement by using cables and spools.        Many applications utilize constant torque spring motors, such as: cord retractors, balance retrieval and return applications, drive motors, cordless curtains, and more. The spring features a high turn design, making it ideal for balancing applications. When they are fully turned, the springs apply a constant torque. You can also guarantee high torque levels. This is due to their compactness and high efficiency.        The function of the constant torque spring motor depends on the design. The size of the spring can vary. Therefore, they make them suitable for use in a variety of applications. We strongly recommend that you consult...

What do you think of the correct sitting posture in office? Relax your shoulders, keep your eyes in front, and keep your eyes balanced at the top of the computer or the top 3 / 1 of the monitor. This is the correct sitting posture of our office. To stand our neck, we need a certain height of the display. The horizontal position of the display is low, and the neck is easy to tilt forward. The cervical spine will obviously feel uncomfortable, very tired, and will cause pressure on the muscles of the neck.      The display bracket is mainly composed of upper support arm, lower support arm, display connector and desktop clamp. The most important core lifting components are in the upper support arm, which supports the display through the deformation of spring or air rod structure in the upper arm. When it comes to the spring in the core lifting part, the reason why the display can rise and fall is that it is designed into a lifter that can adjust the height of the display at will by using the principle of free rise and fall of constant force spring. With the help of the tension of the spring, its height can be adjusted freely. Compared with the column support (the lifting up and down is cumbersome, and the screws need to be adjusted by tools every time) it is simpler to use and more convenient to operate after adding a spring. It only needs a little effort to complete the adjustment, which can be said...

Constant force spring is made by winding the steel strip into a coil. The stress added to the spring determines its diameter, strength, and life. The action of a constant force spring is very similar to the action of stretching a ribbon. Spring stretching and rewinding, the part of the work with the spring itself circle formed tangent, as long as the diameter of the spring is certain, the force of the spring is constant. In extremely long spring designs, varying diameters have an advantage, and the tension increases slightly as the spring is stretched. However, this increase is small relative to the length of the stretch and can be ignored in many applications.Constant force spring is made by winding the steel strip into a coil.

Supermarkets and convenience stores can be seen everywhere. Now more and more people are developing retail. Traditionally, products on shelves are usually placed in order. Some merchants install automatic propellers. After customers buy products, the propellers will push The products at the back are automatically advanced, and when the customer wants to find this product, it is easier to see, which is convenient for the customer to find the desired product and stimulates the customer's desire to buy. Theft of small items in retail stores is a problem that occurs. An ideal form of anti-theft is to create time delays between the dispensing of multiple products. If there is a considerable delay between the distribution of individual products, thieves are less likely to steal the products.        A shelf-delayed pusher equipped with variable force springs can eliminate this problem. The propulsion system includes a pusher, a track and a stop mechanism. The propulsion system includes a resistance mechanism connected to the track and the pusher, and controls the forward movement of the pusher along the track, thereby controlling the speed at which the product is propelled for retrieval by the consumer. When engaged, the stop mechanism prevents the pusher from advancing the product, and the indexing mechanism also limits the forward travel of the pusher to a discrete distance.        The variable force spring can expand the negative gradient and the positive gradient into a spring. It breaks through the influence of the traditional spring affected by Hooke's law, so that the stroke and force are...
