Description

Technical Field

[0001] This application relates to the field of springs, and in particular to a highly stable spring that is easy to assemble and disassemble. Background Technology

[0002] A spring is a mechanical component made of elastic material that can deform under external force and return to its original shape after the external force is removed to store and release energy. It is widely used in various machines and structures for support, cushioning, shock absorption or as a power element. There are many types of springs, including compression springs, tension springs, torsion springs, etc. Each type of spring is suitable for different working conditions and environments according to its shape and purpose.

[0003] To facilitate easy and secure fixing in the corresponding position, some springs are usually welded with corresponding retaining rings at both ends. The retaining rings have several threaded holes. When fixing the spring, the retaining rings are directly fixed in the corresponding position using bolts.

[0004] Traditional springs are prone to fatigue failure after prolonged use, leading to a decline in the overall performance of the mechanical system. This necessitates inspection of the springs. Disassembling a spring requires using tools to loosen multiple bolts, and installing a spring requires tightening multiple bolts to secure it. In scenarios involving frequent disassembly and reassembly, the removal and installation of springs are quite cumbersome. Utility Model Content

[0005] The purpose of this application is to solve the problem mentioned in the background art that when disassembling a spring, multiple bolts need to be turned with tools to remove the spring, and when installing a spring, multiple bolts need to be tightened to fix the spring. In scenarios where springs are frequently disassembled and assembled, the disassembly and assembly of springs are quite troublesome. This application provides a high-stability spring that is easy to disassemble and assemble.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A highly stable spring that is easy to assemble and disassemble includes a spring body, a first fixing ring at one end of the spring body, a second fixing ring at the end of the spring body away from the first fixing ring, and a plurality of threaded holes on both the first fixing ring and the second fixing ring. A quick assembly and disassembly mechanism is provided between the spring body and the first and second fixing rings.

[0008] By adopting the above technical solution, fixing ring one and fixing ring two are fixed in corresponding positions with bolts. Then, the spring body is moved between fixing ring one and fixing ring two. After the spring body enters between fixing ring one and fixing ring two, the quick disassembly and assembly mechanism on fixing ring one and fixing ring two fixes the spring body, completing the installation of the spring body. This makes it convenient to disassemble and install the spring when it needs to be inspected and replaced.

[0009] Furthermore, the quick assembly / disassembly mechanism includes two support rings symmetrically fixed to the spring body. Several circumferentially distributed fixing blocks are fixed on the support rings. Fixing ring one and fixing ring two are each provided with fixing grooves corresponding to the fixing blocks. A snap-fit ​​assembly is provided between fixing ring one, fixing ring two and the support rings.

[0010] By adopting the above technical solution, the support rings at both ends of the spring body abut against the first and second fixing rings, allowing the fixing blocks to enter the corresponding fixing grooves, and then fixing them using the snap-fit ​​assembly. This facilitates the installation and disassembly of the spring body, reducing the inconvenience of installing and disassembling the spring body.

[0011] Furthermore, the snap-fit ​​assembly includes two snap-fit ​​rings that are rotatably connected to fixed ring one and fixed ring two, and the snap-fit ​​rings are provided with a plurality of circumferentially distributed movable grooves. Snap-fit ​​blocks are provided in the movable grooves, and the snap-fit ​​blocks are fixedly connected to the snap-fit ​​rings. Snap-fit ​​grooves corresponding to the snap-fit ​​blocks are provided on the fixed blocks.

[0012] By adopting the above technical solution, the fixing block enters the movable groove on the snap ring from the fixing groove, and then the snap block is inserted into the snap groove on the fixing block, thereby making it convenient to restrict the fixing block.

[0013] Furthermore, a reset block is fixed on one side of the snap ring, and a reset groove is provided on both the first and second fixed rings. The reset block is located in the reset groove, and a reset spring is provided in the reset groove. One end of the reset spring is fixedly connected to the reset block, and the other end of the reset spring is fixedly connected to the corresponding first and second fixed rings.

[0014] By adopting the above technical solution, the reset spring pushes the reset block, and the reset block drives the snap ring, allowing the snap block on the snap ring to insert into the fixed block, thereby reducing the possibility of the snap block detaching from the fixed block.

[0015] Furthermore, a handle is fixed to the reset block, and a protective plate is fixed to one side of the handle, the protective plate corresponding to the reset groove.

[0016] By adopting the above technical solution, the handle is turned so that the reset block moves, and at the same time the protective plate moves, which protects the reset spring. This makes it easy to move the reset block and reduces the possibility of the reset spring bending.

[0017] Furthermore, the snap-fit ​​block has an inclined surface, which corresponds to the fixing block.

[0018] By adopting the above technical solution, the fixed block presses against the inclined surface of the snap-fit ​​block, causing the snap-fit ​​ring to rotate, thereby making it easy to align the snap-fit ​​block with the snap-fit ​​groove on the fixed block.

[0019] Furthermore, limit rods are provided on both sides of the spring body. One end of the limit rod is fixedly connected to one of the support rings, and the other end of the limit rod passes through the other support ring and through the second fixing ring.

[0020] By adopting the above technical solution, the two support rings on the spring body are brought close to each other, and then the support ring with the fixed limit rod drives the limit rod to pass through the other support ring, thereby enabling the spring body to remain stable when compressed.

[0021] Furthermore, each of the two limiting rods is fixed with a limiting ring, which is located between the two support rings.

[0022] By adopting the above technical solution, when the limiting ring on the limiting ring moves to contact the support ring, the limiting ring limits the spring body, thereby reducing the possibility of the spring body being over-compressed.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. This application, before installing the spring body, fixes the first and second fixing rings with bolts to the positions where the spring body needs to be installed. Then, the spring body is compressed, causing the two support rings on the spring body to move between the first and second fixing rings. Then, the spring body is released, and under the push of the spring body, the fixing blocks on the support rings enter the corresponding fixing grooves on the first and second fixing rings. Then, the fixing blocks press against the inclined surface of the snap-fit ​​block, causing the snap-fit ​​ring to rotate. After the fixing blocks abut against the snap-fit ​​ring, the reset spring pushes the reset block, causing the snap-fit ​​ring to reset. The snap-fit ​​ring drives the snap-fit ​​block to insert into the snap-fit ​​groove on the fixing block. When it is necessary to remove the spring body, simply turn the handle, causing the handle to slide the reset block in the reset groove, allowing the reset block to press against the reset spring. Then, the snap-fit ​​block on the snap-fit ​​ring disengages from the snap-fit ​​groove on the fixing block, and then the spring body is removed. This achieves the purpose of facilitating the installation and removal of the spring body and reducing the inconvenience of installing and removing the spring body.

[0025] 2. In this application, after the spring body is fixed, when the spring body is compressed, the two support rings on the spring body move closer to each other. Then, the support ring with the limiting rod fixed moves the limiting rod through the other support ring. Under the restriction of the limiting rod, the spring body remains stable when compressed. When the limiting ring on the limiting ring moves to abut against the support ring, the limiting ring limits the spring body, preventing the spring body from being compressed further. This achieves the purpose of keeping the spring body stable when compressed, while reducing the possibility of the spring body being over-compressed. Attached Figure Description

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0033] This application discloses a highly stable spring that is easy to assemble and disassemble.

[0034] Reference Figure 1 , Figure 2 and Figure 3A high-stability spring that is easy to assemble and disassemble includes a spring body 1, a fixing ring 2 at one end of the spring body 1, a fixing ring 3 at the end of the spring body 1 away from the fixing ring 2, and a number of threaded holes on the fixing ring 2 and the fixing ring 3. A quick assembly and disassembly mechanism 4 is provided between the spring body 1 and the fixing ring 2 and the fixing ring 3. When installing the spring body 1 to the required position, firstly, fix the first fixing ring 2 and the second fixing ring 3 in their corresponding positions using bolts. Then, move the spring body 1 between the first fixing ring 2 and the second fixing ring 3. After the spring body 1 enters between the first fixing ring 2 and the second fixing ring 3, the quick-release mechanism 4 on the first fixing ring 2 and the second fixing ring 3 fixes the spring body 1, completing the installation of the spring body 1. When the spring malfunctions and needs to be replaced, simply use the quick-release mechanism 4 to release the fixation of the first fixing ring 2 and the second fixing ring 3 on the spring body 1, and then remove the spring body 1. By pre-fixing the first fixing ring 2 and the second fixing ring 3 at the position where the spring needs to be installed, and then using the quick-release mechanism 4 to fix the spring body 1 between the first fixing ring 2 and the second fixing ring 3, it is possible to facilitate the disassembly and installation of the spring when it needs to be inspected and replaced.

[0035] Reference Figure 2 , Figure 3 and Figure 4 The quick assembly and disassembly mechanism 4 includes two support rings 41 symmetrically fixed on the spring body 1. Several circumferentially distributed fixing blocks 42 are fixed on the support rings 41. Fixing grooves 43 corresponding to the fixing blocks 42 are opened on the fixing rings 2 and 3. A snap-fit ​​assembly 44 is provided between the fixing rings 2 and 3 and the support rings 41.

[0036] In addition, the snap-fit ​​assembly 44 includes two snap-fit ​​rings 441 that are rotatably connected to the first fixed ring 2 and the second fixed ring 3. The snap-fit ​​rings 441 are provided with a plurality of circumferentially distributed movable grooves 442. Snap-fit ​​blocks 443 are provided in the movable grooves 442. The snap-fit ​​blocks 443 are fixedly connected to the snap-fit ​​rings 441. The fixed blocks 42 are provided with snap-fit ​​grooves corresponding to the snap-fit ​​blocks 443.

[0037] Furthermore, a reset block 445 is fixed on one side of the snap ring 441, and a reset groove 446 is provided on both the first fixed ring 2 and the second fixed ring 3. The reset block 445 is located in the reset groove 446, and a reset spring 444 is provided in the reset groove 446. One end of the reset spring 444 is fixedly connected to the reset block 445, and the other end of the reset spring 444 is fixedly connected to the corresponding first fixed ring 2 and second fixed ring 3.

[0038] Furthermore, a handle 6 is fixed on the reset block 445, and a protective plate 7 is fixed on one side of the handle 6, with the protective plate 7 corresponding to the reset groove 446.

[0039] Furthermore, the snap-fit ​​block 443 has an inclined surface, which corresponds to the fixing block 42.

[0040] Before installing the spring body 1, fix the first fixing ring 2 and the second fixing ring 3 to the positions where the spring body 1 needs to be installed using bolts. Then, compress the spring body 1, causing the two support rings 41 on the spring body 1 to move between the first fixing ring 2 and the second fixing ring 3. Then, release the spring body 1. Under the push of the spring body 1, the fixing block 42 on the support ring 41 enters the corresponding fixing groove 43 on the first fixing ring 2 and the second fixing ring 3. Then, the fixing block 42 presses against the inclined surface of the snap-fit ​​block 443, causing the snap-fit ​​ring 441 to rotate. After the fixing block 42 abuts against the snap-fit ​​ring 441, the reset spring 444 pushes the reset block 445, causing the snap-fit ​​ring 441 to reset. The snap ring 441 drives the snap block 443 to insert into the snap groove on the fixing block 42. When it is necessary to remove the spring body 1, simply turn the handle 6 to make the handle 6 drive the reset block 445 to slide in the reset groove 446, so that the reset block 445 squeezes the reset spring 444. Then the snap block 443 on the snap ring 441 disengages from the snap groove on the fixing block 42. Then the spring body 1 is removed. By making the support rings 41 at both ends of the spring body 1 abut against the fixing ring 1 2 and the fixing ring 2 3, and then using the snap block 443 to restrict the fixing block 42, it is possible to facilitate the installation and removal of the spring body 1 and reduce the inconvenience of installing and removing the spring body 1.

[0041] Reference Figure 2 and Figure 3 Limiting rods 5 are provided on both sides of the spring body 1. One end of the limiting rod 5 is fixedly connected to one of the support rings 41, and the other end of the limiting rod 5 passes through the other support ring 41 and through the second fixing ring 3.

[0042] In addition, limit rings 8 are fixed on both limit rods 5, and the limit rings 8 are located between the two support rings 41.

[0043] After the spring body 1 is fixed, when the spring body 1 is compressed, the two support rings 41 on the spring body 1 move closer to each other. Then, the support ring 41 with the limiting rod 5 is fixed and drives the limiting rod 5 to pass through the other support ring 41. Under the restriction of the limiting rod 5, the spring body 1 remains stable when compressed. When the limiting ring 8 on the limiting ring 8 moves to abut against the support ring 41, the limiting ring 8 limits the spring body 1, preventing the spring body 1 from being compressed further. By using the limiting rod 5 and the limiting ring 8 to restrict the two support rings 41, the spring body 1 can remain stable when compressed, while reducing the possibility of the spring body 1 being over-compressed.

[0044] Working principle: When installing the spring body 1 to the required position, firstly, fix the first fixing ring 2 and the second fixing ring 3 in their corresponding positions using bolts. Then, compress the spring body 1, causing the two support rings 41 of the spring body 1 to move between the first fixing ring 2 and the second fixing ring 3. Then, release the spring body 1. Under the push of the spring body 1, the fixing block 42 on the support ring 41 enters the corresponding fixing groove 43 on the first fixing ring 2 and the second fixing ring 3. Then, the fixing block 42 presses against the inclined surface of the snap-fit ​​block 443, causing the snap-fit ​​ring 441 to rotate. After the fixing block 42 abuts against the snap-fit ​​ring 441, the return spring 444 pushes the return block 445, causing the snap-fit ​​ring 441 to return to its original position. The snap-fit ​​ring 441 then drives the snap-fit ​​block 443 to insert into the snap-fit ​​on the fixing block 42. When the spring body 1 needs to be removed, simply turn the handle 6 to make the handle 6 move the reset block 445 in the reset groove 446, so that the reset block 445 squeezes the reset spring 444. Then the snap block 443 on the snap ring 441 disengages from the snap groove on the fixing block 42. Then the spring body 1 is removed. When the spring body 1 is compressed, the two support rings 41 on the spring body 1 move closer to each other. Then the support ring 41 with the limit rod 5 fixed moves the limit rod 5 through the other support ring 41. Under the restriction of the limit rod 5, the spring body 1 remains stable when compressed. When the limit ring 8 on the limit ring 8 moves to contact the support ring 41, the limit ring 8 limits the spring body 1, so that the spring body 1 cannot be compressed further.
