Description

Technical Field

[0001] The utility model relates to the technical field of washers, in particular to an anti-fracture washer. Background Art

[0002] A washer is a part used between a connector and a screw or nut to prevent the screw or nut from rotating and falling off when receiving an external force. At present, most of the existing washers only have a single rubber sheet structure, so they do not have good anti-pulling, extrusion, and tearing abilities, and are easily deformed or broken, affecting the normal use of the equipment. For this reason, we propose an anti-fracture washer to solve the problems raised in the above background art. Content of the Utility Model

[0003] The purpose of the utility model is to provide an anti-fracture washer to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: an anti-fracture washer, including a skeleton plate, an upper washer, and a lower washer. The upper washer and the lower washer are respectively coated and connected to the upper and lower sides of the skeleton plate. The skeleton plate, the upper washer, and the lower washer all adopt an annular structure. The top and bottom of the skeleton plate are respectively provided with no less than four connecting grooves around. The opposite sides of the upper washer and the lower washer are integrally formed with plugging parts adapted to the connecting grooves. The edges of the opposite sides of the upper washer and the lower washer are respectively integrally formed with an upper connecting part and a lower connecting part.

[0005] Further, a first annular glue groove is opened at the top of the lower connecting part, and an annular plugging strip is integrally formed at the position corresponding to the first annular glue groove at the bottom of the upper connecting part.

[0006] Further, no less than four weight-reducing holes are equidistantly opened on the skeleton plate, and a reinforcing strut is fixedly connected between the inner walls of the opposite sides of the weight-reducing holes.

[0007] Further, inner metal sleeves and outer metal sleeves are respectively arranged on the inner ring surfaces and outer ring surfaces of the skeleton plate, the upper washer, and the lower washer.

[0008] Further, a second annular glue groove is opened on the outer surface of the inner metal sleeve, and a third annular glue groove is opened on the inner surface of the outer metal sleeve.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] After placing the lower washer on the tabletop, apply some glue to the connection grooves on the skeleton plate, facing the insertion parts of the lower washer, to achieve the connection between the skeleton plate and the lower washer. At this time, the outer ring surface of the skeleton plate fits with the inner ring surface of the lower connection part. After injecting a circle of glue into the first annular glue groove, insert the insertion part at the bottom of the upper washer into the connection groove, facing it, to achieve the connection between the upper washer and the skeleton plate. At this time, the annular insertion strip also inserts into the inside of the first annular glue groove, forming the connection between the upper washer and the lower washer. At the same time, injecting glue at the edge can prevent warping at the edges during long-term use. Finally, glue can be injected into the second annular glue groove and the third annular glue groove, and inserted into the inner ring surface and the outer ring surface of the assembled upper and lower washers respectively. While strengthening the connection tightness of the upper and lower washers, it also improves the anti-extrusion and impact resistance of the overall side of the washer. This anti-fracture washer has a reasonable structural design and is convenient to use. It adopts an inner skeleton structure to form the assembly connection of two separate washers, making the whole have a relatively high strength and not easily deformed or fractured due to pulling, extrusion or tearing, ensuring the normal operation of the equipment and having a long service life.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0015] Please refer to Figure 1-2 , an anti-fracture washer, comprising a skeleton plate 1, an upper washer 2 and a lower washer 3. The upper washer 2 and the lower washer 3 are respectively wrapped and connected to the upper and lower sides of the skeleton plate 1. The skeleton plate 1, the upper washer 2 and the lower washer 3 all adopt an annular structure. There are no less than four connection grooves 4 respectively formed around the top and bottom of the skeleton plate 1. One-piece formed connection parts 5 adapted to the connection grooves 4 are integrally formed on the opposite sides of the upper washer 2 and the lower washer 3. Upper connection parts 6 and lower connection parts 7 are integrally formed on the edges of the opposite sides of the upper washer 2 and the lower washer 3 respectively.

[0016] Specifically, a first annular glue groove 8 is formed at the top of the lower connecting portion 7, and an annular insertion strip 9 is integrally formed and connected at a position corresponding to the first annular glue groove 8 at the bottom of the upper connecting portion 6.

[0017] Specifically, no less than four weight-reducing holes 10 are equidistantly formed in the skeleton plate 1, and a reinforcing strut 11 is fixedly connected between the inner walls on the opposite sides of the weight-reducing holes 10. The weight-reducing holes 10 can reduce the overall mass of the washer, and the reinforcing strut 11 improves the overall strength.

[0018] Specifically, inner metal sleeves 12 and outer metal sleeves 13 are respectively provided on the inner ring surfaces and outer ring surfaces of the skeleton plate, the upper washer 2 and the lower washer 3.

[0019] Specifically, a second annular glue groove 14 is formed on the outer surface of the inner metal sleeve 12, and a third annular glue groove 15 is formed on the inner surface of the outer metal sleeve 13.

[0020] This anti-fracture washer has a reasonable structural design and is convenient to use. It adopts an inner skeleton structure to form the assembly connection of two separate washers, making the whole have high strength and not easily deformed or fractured due to pulling, squeezing or tearing, ensuring the normal operation of the equipment and having a long service life.

[0021] During use, after placing the lower washer 3 on the tabletop, apply some glue to the connection groove 4 on the skeleton plate 1, and align it with the insertion portion 5 of the lower washer 3 to realize the connection between the skeleton plate 1 and the lower washer 3. At this time, the outer ring surface of the skeleton plate 1 fits with the inner ring surface of the lower connecting portion 7. After injecting a circle of glue into the first annular glue groove 8, insert the insertion portion 5 at the bottom of the upper washer 2 into the connection groove 4 to realize the connection between the upper washer 2 and the skeleton plate 1. At this time, the annular insertion strip 9 also inserts into the first annular glue groove 8 to form the connection between the upper washer 2 and the lower washer 3. At the same time, injecting glue at the edge can prevent warping of each other during long-term use. Finally, glue can be injected into the second annular glue groove 14 and the third annular glue groove 15, and they are respectively inserted into the inner ring surface and the outer ring surface of the assembled upper and lower washers, which not only strengthens the connection tightness between the upper and lower washers, but also improves the anti-extrusion and impact resistance of the overall side surface of the washer.

[0022] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
