Power springs applied in barbell weightlifting protection devices

 Barbell is a kind of core training sports training equipment, which is also used in weight lifting. Barbell sports is a kind of weight training. Barbell training equipment can be used to improve muscle strength training, and barbell can also be used for core training to promote overall coordination.

The barbell is heavier than other fitness equipment, which is also prone to accidents. The existing barbell lacks corresponding protective measures when used, which is easy to hurt users or damage the barbell.

The above problems can be solved by the power spring. Add the barbell weight lifting protection device of the power spring. The utility model relates to the technical field of fitness equipment, including a base plate, and also includes: a placing table connected with the base plate; Barbell, butting with the placing table; One end of the protection mechanism is connected with the placing table, and the other end is connected with the barbell. The protection mechanism comprises an inductor, a linkage component and a clamping component; The holding mechanism is connected with the barbell.

Athletes hold the barbell through the holding mechanism to exercise, and the barbell drives the linkage component to move. When the human body is released, the barbell drives the linkage component to move quickly under its own gravity. When the sensor senses that the linkage component moves faster, the sensor starts the operation of the clamping component, and the clamping component clamps the linkage component, hinders the movement of the linkage component, and then hinders the movement of the barbell, so as to protect the human body.

  So how does barbell work? People hold the barbell, and then drive the barbell to move longitudinally. The barbell drives the connecting rope 4 to move. Under the force of the power spring 6, the connecting roller 5 rotates. The connecting roller 5 cooperates with the longitudinal movement of the barbell to pay off or wind up the connecting rope 4, and the connecting roller 5 drives the gear 7 to rotate at the same time.

  In the device, the power spring plays a very important role. The power spring is rolled from steel strip. In use, a spring box is required to limit its outer diameter. The center of the spring is connected with the shaft. When an external force is applied to make the shaft rotate relative to the spring, the spring will roll on the shaft center and store the torque. When the external force disappears, the spring will produce the torque on the shaft or the spring box.

The advantage of power spring is that it can be divided into natural power spring and pre force power spring according to its relaxed shape. In contrast, pre tensioned power springs can store 25% to 55% more torque and provide more effective turns.

  Qianye precision power spring is made of 301 high-strength stainless steel. Other materials can be used according to the requirements of customized applications. Its main feature is to provide high torque normal residual stress per unit deformation.

  Shenzhen Qianye Precision Metal Co., Ltd. has more than 20 years of production experience in spring, and has put forward various application designs and solutions for spring. We sincerely suggest that customers can obtain consulting services with our R&D engineers at the early stage of product introduction and R&D. According to the needs of customers and assist in product design, development, proofing, so that your products can find the best solution to meet your application needs.
