Description

Technical Field

[0001] The utility model relates to the technical field of compression springs, in particular to an anti-deformation compression spring structure. Background Art

[0002] Compression springs, also known as helical springs that withstand axial pressure, work by using multiple open coils to provide resistance to external pressure. When subjected to an external load, the spring contracts and deforms, storing deformation energy. When the external load is removed, the spring attempts to return to its original shape, thereby providing thrust or restoring force.

[0003] However, compression springs are prone to deformation during use due to excessive pressure, which can affect their proper function. To address this issue, patent publication number CN218935112U discloses a deformation-resistant grooved spring. During use, when the top plate is pressed downward under pressure, the spring wire (i.e., the spring body) expands and contracts, and the adjusting rod simultaneously enters the interior of the connecting sleeve. The connecting sleeve moves within the main sleeve, relieving the pressure on the top plate and effectively preventing deformation of the spring wire. Furthermore, the arrangement of a secondary sleeve and telescopic rod provides support and stability between the top and bottom plates, effectively preventing overall deformation.

[0004] However, the above solution still has some shortcomings during implementation. The spring wire (i.e., the spring body) is fixedly installed between the top plate and the bottom plate, which makes it inconvenient to disassemble and assemble the spring body when it is replaced later. At the same time, there is a large gap between the connecting sleeve, the adjusting rod and the spring body. When the spring body is compressed, it is very easy to produce lateral deformation, thereby affecting its performance and service life. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings in the prior art, the utility model provides an anti-deformation compression spring structure.

[0006] The technical implementation plan of the utility model is: an anti-deformation compression spring structure, including a base plate, a fixed limit block, a sliding limit block, a cover plate, a spring body and a buffer assembly, the top of the base plate is fixedly connected to the fixed limit block, the sliding limit block is slidably arranged on the fixed limit block, the top of the sliding limit block is fixedly connected to the cover plate, a spring body is arranged between the cover plate and the base plate, the spring body is arranged on the periphery of the fixed limit block and the sliding limit block, and the inner side of the spring body is kept in contact with the fixed limit block and the sliding limit block, and a buffer assembly for buffering the rebound force after the spring body is compressed is provided on the base plate.

[0007] More preferably, the buffer assembly includes a sleeve, a slide rod, a screw, a nut and a buffer block. The sleeve is symmetrically fixedly connected to the top of the base plate, the slide rods are slidably connected in the two sleeves, the tops of the two slide rods are fixedly connected with screws, two reserved holes are provided on the cover plate, the two screws can respectively pass through the two reserved holes, the two screws are threaded with nuts, and the lower ends of the two slide rods are provided with buffer blocks.

[0008] More preferably, a buffer pad is further included, and a buffer pad is provided at the lower part of the fixed limit block.

[0009] More preferably, an alloy ring is further included, and the bottom of the cover plate and the top of the base plate are both fixedly connected with the alloy ring.

[0010] More preferably, a pad is further included, and the top of the cover plate is symmetrically fixedly connected with the pad.

[0011] More preferably, the surface of the spring body is sprayed with an anti-corrosion coating.

[0012] The beneficial effects of the utility model are as follows: the fixing method of the cover plate by the nut and the screw facilitates the installation or disassembly of the spring body; the setting of the fixed limit block and the sliding limit block ensures that the spring body will not be over-compressed, and at the same time limits the possibility of the spring body undergoing lateral deformation during the compression process; the cooperation of the sleeve, the slide rod and the buffer block achieves a buffering effect on the resetting speed of the spring body, further protecting the spring body and preventing it from unnecessary deformation.

[0018] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the present invention are shown. However, the present invention can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the scope of the invention to those skilled in the art.

[0019] Example: An anti-deformation compression spring structure, such as Figures 1-4 As shown, it includes a base plate 1, a fixed limit block 2, a sliding limit block 3, a cover plate 4, a spring body 5 and a buffer assembly. The top of the base plate 1 is welded and fixed with a fixed limit block 2, and a sliding limit block 3 is slidingly set on the fixed limit block 2. The cover plate 4 is welded and fixed on the top of the sliding limit block 3. A spring body 5 is arranged between the cover plate 4 and the base plate 1. The spring body 5 is arranged on the periphery of the fixed limit block 2 and the sliding limit block 3, and its inner side is kept in contact with the fixed limit block 2 and the sliding limit block 3. The upper and lower ends of the spring body 5 are only in contact with the cover plate 4 and the base plate 1, and there is no connection relationship. The surface of the spring body 5 is sprayed with an anti-corrosion coating to extend its service life and prevent corrosion problems caused by environmental factors. A buffer assembly is provided on the base plate 1 for buffering the rebound force of the spring body 5 after compression.

[0020] like Figure 1 and Figure 3 As shown, the buffer assembly includes a sleeve 6, a slide rod 7, a screw 8, a nut 9 and a buffer block 10. The sleeve 6 is symmetrically welded and fixed on the top of the base plate 1. The two sleeves 6 are slidably connected with the slide rod 7. The tops of the two slide rods 7 are welded and fixed with screws 8. Two reserved holes are provided on the cover plate 4. The two screws 8 can respectively pass through the two reserved holes. The two screws 8 are threadedly connected with nuts 9, and the lower ends of the two slide rods 7 are provided with buffer blocks 10.

[0021] First, the user places the spring body 5 on the base plate 1, at this time ensuring that the inner side of the spring body 5 fits tightly with the fixed limit block 2, then passes the sliding limit block 3 through the upper part of the spring body 5 and inserts it into the fixed limit block 2, at the same time, ensuring that the two screws 8 can smoothly pass through the reserved holes on the cover plate 4, next, the user tightens the two nuts 9 on the two screws 8 respectively to fix the cover plate 4. During use, when the spring body 5 is compressed to a certain length, the bottom of the sliding limit block 3 will fit tightly with the fixed limit block 2, thereby ensuring that the spring body 5 will not be over-compressed, thereby preventing it from being deformed due to excessive force. At the same time, due to the fixed limit Block 2 and the sliding limit block 3 are both in close fit with the inner side of the spring body 5, effectively limiting the possibility of lateral deformation of the spring body 5 during the compression process. When the pressure acting on the spring body 5 disappears, the spring body 5 will quickly reset upward under the action of its own reset force. This reset process will drive the cover plate 4 and the slide rod 7 connected thereto to move upward together. In the process of the slide rod 7 resetting upward, the buffer block 10 provided at its lower end will contact the upper part of the sleeve 6, thereby achieving a buffering effect on the reset speed of the spring body 5, thereby avoiding the impact force generated by the sudden reset of the spring body 5, further protecting the spring body 5 and preventing it from unnecessary deformation.

[0022] like Figure 2 and Figure 4 As shown, a buffer pad 11 is also included, and a buffer pad 11 is provided at the lower part of the fixed limit block 2.

[0023] By providing the buffer pad 11, an effective buffer layer is formed between the sliding limit block 3 and the fixed limit block 2, which can significantly reduce the impact force generated when the two collide, protect the various components from damage, and extend the service life of the overall structure.

[0024] like Figure 2 and Figure 3 As shown, an alloy ring 12 is also included. The alloy ring 12 is welded and fixed to the bottom of the cover plate 4 and the top of the base plate 1.

[0025] By fixing the alloy rings 12 on the top and bottom of the cover plate 4 and the base plate 1, not only the overall strength and stability of the structure are enhanced, but also the spring body 5 is effectively prevented from causing scratches or wear to the cover plate 4 and the base plate 1 during compression and reset.

[0026] like Figure 1 As shown, a pad 13 is also included, and the pad 13 is symmetrically welded and fixed on the top of the cover plate 4.

[0027] By providing the spacer 13 , the height of the cover plate 4 is raised so as to be flush with the top of the screw 8 , thereby providing an additional support area and making the connection between the cover plate 4 and the workpiece more stable and reliable.

[0028] Although the present disclosure has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents. Therefore, the scope of the present disclosure should not be limited to the above-described embodiments, but should be determined not only by the appended claims but also by the equivalents of the appended claims.
