DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 6 The embodiment of the present invention provides a high-stability spring that is easy to disassemble and assemble, including a spring body 1, two fixing seats 3 and two locking pins 4. Lugs 2 are provided at both ends of the spring body 1, and a through hole 301 is provided on the inner side of the two fixing seats 3. The two locking pins 4 are connected to the handle 5 through a reset spring 6, and a positioning mechanism 7 is provided on the outer side of the two lugs 2.

[0021] Specifically, the spring body 1 is a core component, and lugs 2 are provided at both ends thereof for convenient connection with other components, ensuring that the role of the spring in the system can be effectively played, which is the basis for realizing the function of the spring. The two fixing seats 3 and the perforations 301 on the inner side thereof provide a stable support structure for the installation of the spring body 1, ensuring that the position of the spring is relatively fixed during the working process, which is conducive to maintaining the stability of the system and enabling the spring to play a role in the appropriate position. The two locking pins 4 are connected to the handle 5 through the reset spring 6. During installation, the operator can operate the locking pins 4 through the handle 5 to insert the lugs 2 to achieve fixation, ensuring the tightness of the connection between the spring body 1 and the fixing seat 3. The positioning mechanism 7 on the outside of the two lugs 2 can accurately determine the installation position of the spring body 1, prevent the spring from being offset during use, enhance the stability of the spring, avoid the risk of accidental falling off under stress, and ensure safety in use.

[0022] See also Figure 4-Figure 5 The positioning mechanism 7 includes a positioning box 701 , a second through hole 709 is formed on the inner side of the positioning box 701 , a lug 2 is arranged on the inner side of the positioning box 701 , a groove 702 is formed on the inner side of the fixing seat 3 , and the positioning box 701 is plugged into the inner wall of the groove 702 .

[0023] Specifically, the lug 2 is placed in the inner space of the positioning box 701 in cooperation with the lug 2 , thereby achieving preliminary accommodation and positioning of the lug 2 and ensuring preliminary determination of the end position of the spring body 1 .

[0024] The second through hole 709 of the positioning box 701 cooperates with the lug 2 and the subsequent locking pin 4 to provide a channel for the locking pin 4 to pass through, thereby ensuring the feasibility of fixed connection.

[0025] By cooperating with the groove 702 of the fixing seat 3 through the outer wall of the positioning box 701, the positioning box 701 is inserted into the inner wall of the groove 702, thereby achieving the stable placement of the positioning box 701 itself, thereby maintaining the stability of the installation position of the spring body 1, enhancing the stability of the overall structure, and avoiding accidental displacement of the spring body 1.

[0026] See also Figure 4 and Figure 5 A fixing component 1 is provided on the top of the positioning box 701. The fixing component 1 is used to fix the positioning box 701 after it is positioned. The fixing component 1 includes two connecting plates 703. The two connecting plates 703 are respectively fixedly connected to the two sides of the top of the positioning box 701. A plug post 705 is fixedly connected to the top of the connecting plate 703. Two connecting grooves 704 are provided on the inner side wall of the groove 702. A slot 706 is provided on the inner side wall of the connecting groove 704. The connecting plate 703 is plugged into the connecting groove 704, and the plug post 705 is plugged into the slot 706.

[0027] Specifically, by cooperating with the connecting plate 703 on the top of the positioning box 701 and the connecting groove 704 on the inner wall of the groove 702 of the fixing seat 3, the connecting plate 703 is inserted into the connecting groove 704, thereby realizing the initial positioning and limiting of the positioning box 701 in the horizontal direction, and enhancing the installation stability of the positioning box 701.

[0028] By cooperating with the slot 706 on the inner wall of the connecting groove 704 through the plug 705 on the top of the connecting plate 703, the plug 705 is inserted into the slot 706, which further limits the displacement of the positioning box 701 in the vertical direction, ensures the tight connection between the positioning box 701 and the fixing seat 3, effectively prevents the positioning box 701 from loosening during use, and improves the stability of the overall structure.

[0029] See also Figure 4 and Figure 5 A fixing component 2 is provided on the outer side of the positioning box 701, and the fixing component 2 is used to fix the positioning box 701 after positioning. The fixing component 2 includes two reinforcing plates 707, and the two reinforcing plates 707 are respectively fixedly connected to the left and right sides of the outer side of the positioning box 701. Two reinforcing grooves 708 are provided on the inner side wall of the groove 702, and the reinforcing plates 707 are plugged into and matched with the reinforcing grooves 708.

[0030] Specifically, by cooperating with the reinforcing plates 707 on the left and right sides of the outside of the positioning box 701 and the reinforcing grooves 708 on the inner walls of the groove 702 of the fixing seat 3, the reinforcing plates 707 are inserted into the reinforcing grooves 708 to provide firm support to the lateral direction of the positioning box 701, thereby enhancing the firmness of the connection between the positioning box 701 and the fixing seat 3, further improving the stability of the overall structure, and effectively reducing the risk of displacement or loosening due to external forces and other factors.

[0031] See also Figure 6 The reset spring 6 is used to automatically reset the locking pin 4 to the initial position after the handle 5 is released.

[0032] Specifically, through the elastic restoring force of the reset spring 6, in cooperation with the locking pin 4, when the handle 5 is released, the locking pin 4 is pushed to move to the initial position by its own elastic force, thereby realizing the automatic return of the locking pin 4. The card bead then enters the locking pin 4, facilitating the subsequent rapid disassembly and assembly of the spring, improving the convenience and repeatability of the operation, and reducing the tedious steps and time cost of manual resetting.

[0033] See also Figure 5 The outer surface of the handle 5 is provided with anti-slip patterns to improve the grip during operation.

[0034] Specifically, by means of the anti-slip texture on the outer surface of the handle 5 cooperating with the operator's hand, when the operator holds the handle 5 to push, pull or rotate it, the friction between the hand and the handle 5 is increased, so that the operator can control the handle 5 more steadily and accurately, thereby effectively improving the accuracy and efficiency of the operation and reducing the possibility of operational errors due to hand slippage.

[0035] See also Figure 3 and Figure 5 The locking pin 4 passes through the through hole 1 301 on the fixing seat 3 and the through hole 2 709 on the positioning box 701 in sequence, and is connected to the fixing seat 3 through the through hole on the lug 2 to achieve positioning and fixing of the spring body 1.

[0036] Specifically, through the rigid structure of the locking pin 4, it cooperates with the through hole 301 on the fixing seat 3, so that it can accurately pass through the through hole 301 to achieve preliminary positioning guidance; cooperates with the through hole 709 on the positioning box 701 to further accurately guide the path of the locking pin 4; and then cooperates with the through hole on the lug 2 to tightly connect the spring body 1 and the fixing seat 3, thereby achieving a firm fixation of the spring body 1, enhancing the stability of the spring during operation, avoiding its displacement or falling off, and ensuring the reliable operation of the entire device.

[0037] See also Figure 3 and Figure 5 The through hole 1 301 and the through hole 2 709 are aligned on the axis, and the locking pin 4 passes through the axis to ensure that the locking pin 4 can be accurately inserted into and fix the spring body 1 .

[0038] Specifically, through the consistent design of perforation 1 301 and perforation 2 709 on the axis, in cooperation with the locking pin 4, the locking pin 4 can pass smoothly along the unified axis, avoiding the problem of difficult insertion or inaccurate fixation due to perforation position deviation, achieving efficient and accurate fixation of the spring body 1, ensuring the stability and reliability of the spring installation process, and improving the assembly accuracy and working performance of the entire device.

[0039] Working principle: First, when installing the spring body 1, place the lugs 2 at both ends of the spring body 1 on the inner side of the corresponding positioning box 701 of the positioning mechanism 7. Then, align the end with the lug 2 and the positioning box 701 with the groove 702 of the fixing seat 3, and insert the positioning box 701 into the inner wall of the groove 702. At this time, the fixing components 1 and 2 on the positioning box 701 come into play, the connecting plate 703 is inserted into the connecting groove 704, the plug post 705 is inserted into the slot 706, and the reinforcing plate 707 is inserted into the reinforcing groove 708, so as to realize the preliminary fixation of the positioning box 701 on the fixing seat 3, thereby determining the position of the spring body 1.

[0040] Secondly, the operator holds the handle 5 with anti-slip grooves and pushes it toward the fixing seat 3 to drive the locking pin 4 to move. Since the through hole 1 301 and the through hole 2 709 are consistent on the axis, the locking pin 4 can pass through the through hole 1 301 on the fixing seat 3 and the through hole 2 709 on the positioning box 701 in sequence, and be inserted into the hole on the lug 2 to connect with the fixing seat 3. Then the handle 5 is rotated to drive the card bead out, thereby achieving further stable fixation of the spring body 1.

[0041] Finally, when the spring needs to be removed, the handle 5 is rotated in the opposite direction, the card bead enters the locking pin 4, and the elastic force of the reset spring 6 resets the handle 5. By pulling the handle 5, the locking pin 4 is withdrawn from the hole on the lug 2, and then the positioning box 701 can be pulled out of the groove 702 of the fixing seat 3, so that the spring body 1 can be easily taken out to complete the disassembly process.
