Abstract
Description
Technical Field
[0001] This utility model relates to the field of coil spring technology, and in particular to a coil spring that is easy to install. Background Technology
[0002] Coil springs, also known as clockwork springs, are generally made of elastic materials such as spring steel and stainless steel. They are helical in shape and are made of thin metal strips or steel wires wound together. They have special structures at the ends, such as hooks, eyelets, and lugs. These structures are mainly used to connect other components or to fix the position of the coil spring itself. Its working principle is based on elastic deformation and energy storage. When it is twisted or rotated by an external force, the coil spring stores energy. When the external force is removed, the coil spring releases the stored energy, thereby generating a restoring force. This characteristic makes it widely used in many fields.
[0003] In terms of actual installation, traditional coil springs are mostly connected to the corresponding shafts using interference fit or bolt installation. However, interference fit requires external force to expand the coil spring to fit into the shaft, making the installation and disassembly process extremely inconvenient. In scenarios where coil springs need to be replaced frequently, it will consume a lot of time and effort. Although bolt installation is relatively flexible, it has the problem of taking up a lot of space. In vibrating environments, additional anti-loosening measures are required, which is also not conducive to quick installation and disassembly. This results in a poor overall user experience and greatly reduces its practicality. Utility Model Content
[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0006] An easy-to-install coil spring includes a coil spring body, a fixing mechanism is provided at the middle position of the coil spring body, and the fixing mechanism is fixedly connected to the coil spring body. The fixing mechanism is provided with a limiting component.
[0007] The fixing mechanism includes a fixing seat, which is located at the center of the inner side of the coil spring body and is fixedly connected to one end of the coil spring body. The inner wall of the fixing seat is symmetrically provided with sliding grooves.
[0008] As an improved technical solution, the fixing mechanism further includes a drive plate. The side wall of the fixing seat has a cavity, and the drive plate is rotatably installed in the cavity. A torsion spring is provided on one side of the drive plate in the cavity, and the two ends of the torsion spring are fixedly connected to the inner wall of one side of the cavity and the drive plate, respectively. The drive plate has symmetrically arranged inserts on the side away from the torsion spring, and one end of the inserts extends to the inner side of the fixing seat. Each insert is provided with a limiting post at a corresponding position on the side of the inserts near the drive plate. A drive rod is connected to the side of the drive plate away from the torsion spring, and one end of the drive rod extends to the outer side of the fixing seat.
[0009] As an improved technical solution, the drive plate has symmetrically opened rail grooves on one side that are adapted to the limiting post, and the two rail grooves are symmetrically distributed in a circle, and the rail grooves are arc-shaped.
[0010] As an improved technical solution, one end of the fixed base is provided with a second rail groove adapted to the drive rod, and the second rail groove is an arc-shaped structure with the same center as the fixed base.
[0011] As an improved technical solution, the drive plate has an annular structure, a limiting ring is fixedly installed in the cavity, the drive plate is movably sleeved on the outside of the limiting ring, and the inner wall of the drive plate is provided with an annular groove that matches the limiting ring.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:
[0014] 1.

[0027] like Figure 1 - Figure 4 As shown in the figure, this embodiment provides a coil spring that is easy to install, including a coil spring body 1, a fixing mechanism 2 is provided at the middle position of the coil spring body 1, and the fixing mechanism 2 is fixedly connected to the coil spring body 1, and a limiting component is provided inside the fixing mechanism 2; the fixing mechanism 2 includes a fixing seat 3, and the fixing seat 3 is located at the inner center position of the coil spring body 1, and the fixing seat 3 is fixedly connected to one end of the coil spring body 1, and the inner wall of the fixing seat 3 is symmetrically provided with sliding grooves 5. In this example, the fixing mechanism 2 also includes a drive plate 7. A cavity 4 is opened in the side wall of the fixing seat 3. The drive plate 7 is rotatably installed in the cavity 4. A torsion spring 8 is provided on one side of the drive plate 7 in the cavity 4. The two ends of the torsion spring 8 are fixedly connected to the inner wall of one side of the cavity 4 and the drive plate 7, respectively. A plug 9 is symmetrically provided on the side of the drive plate 7 away from the torsion spring 8. The inner end of the plug 9 extends to the inner side of the fixing seat 3. A limiting post 10 is provided at the corresponding position on the side of the plug 9 near the drive plate 7. A drive rod 11 is connected to the side of the drive plate 7 away from the torsion spring 8. One end of the drive rod 11 extends to the outer side of the fixing seat 3. So that the coil spring body 1 can be quickly installed, fixed or disassembled through the fixing mechanism 2, improving installation efficiency and making it more convenient to use.
[0028] In this example, the drive plate 7 has symmetrically opened rail grooves 12 that are adapted to the limiting post 10 on one side, and the two rail grooves 12 are symmetrically distributed in a circle. The rail grooves 12 are arc-shaped so that the inner wall of the rail grooves 12 can be used to squeeze and push the limiting post 10, thereby driving the insert block 9 to move up and down.
[0029] In this example, one end of the fixed base 3 is provided with a second rail groove 13 that is adapted to the drive rod 11, and the second rail groove 13 is an arc-shaped structure with the fixed base 3 as the center, so as to limit and guide the drive rod 11 through the second rail groove 13.
[0030] In this example, the drive plate 7 is a ring structure, and a limiting ring 6 is fixedly installed in the cavity 4. The drive plate 7 is movably sleeved on the outside of the limiting ring 6, and the inner wall of the drive plate 7 is provided with an annular groove that matches the limiting ring 6, so as to limit and guide the drive plate 7, allowing the drive plate 7 to rotate around the limiting ring 6.
[0031] like Figure 1 , Figure 2 and Figure 3 As shown in the example, the limiting component includes a magnetic cover 14, which is sleeved on the outer side of the drive rod 11 at one end of the fixed base 3. The fixed base 3 has symmetrical magnetic grooves 15 that are adapted to the magnetic cover 14 at one end, and the magnetic grooves 15 correspond to the two ends of the rail groove 13, so as to limit the drive rod 11, thereby improving the installation and fixing effect of the coil spring body 1 and preventing accidental contact with the drive rod 11 to move, which would affect the installation and fixing effect of the coil spring body 1.
[0032] During use and installation, first drag the drive rod 11 to move it within the second rail groove 13, causing the drive rod 11 to rotate the drive plate 7 located in the cavity 4 of the fixed seat 3. The drive plate 7 rotates around the limiting ring 6 and twists the torsion spring 8. When the drive plate 7 rotates, the first rail groove 12 on it pushes the limiting post 10 on the insert 9 through its inner wall, thereby causing the limiting post 10 to move the insert 9 connected to it, so that the two inserts 9 move outwards synchronously, thereby moving the inner end of the insert 9 out of the inner side of the fixed seat 3. Then, the fixed seat 3 is sleeved on the outer side of the shaft on the equipment to be installed, and the sliding groove 5 engages with the protrusion on the outer wall of the shaft to achieve the initial positioning and guidance of the fixed seat 3. Releasing the force applied to the drive rod 11 will cause the drive plate 7 to rotate and reset under the torque of the torsion spring 8, thereby driving the insert block 9 to reset and insert one of the inner ends of the insert block 9 into the corresponding insertion hole on the central shaft of the installation equipment, thus completing the installation. For disassembly, pull the drive rod 11 to move it in the second rail groove 13 and repeat the above steps to retract the insert block 9, thereby removing the coil spring body 1. After installation, the magnetic cover 14 is placed on the outside of the drive rod 11 at the outer end of the fixed base 3, and one end of the magnetic cover 14 is inserted into the corresponding magnetic groove 15, so that the magnetic cover 14 is attracted in the magnetic groove 15, preventing the drive rod 11 from moving accidentally, thus ensuring that the coil spring body 1 is installed firmly and is more practical.
[0033] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
