Description

Technical Field

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

[0002] Anti-loosening washers are also known as anti-loosening washers, self-locking washers, self-locking washers, DIN25201 anti-loosening washers, double-stack self-locking anti-loosening washers and double-stack wedge anti-loosening washers. The new type of washers are composed of two washers. Their unique embedded structure changes the traditional washers that mainly rely on friction to achieve anti-loosening. Instead, they adopt the most advanced anti-loosening technology in the world and use the tension between the two washers to achieve the dual effects of anti-loosening and tightening.

[0003] The gaskets of existing anti-loosening washers are often integrally formed. After long-term use, the convex grooves or tooth surfaces on the gasket surface are easily worn. If any of the convex grooves or tooth surfaces are worn, the gasket must be replaced as a whole, which increases the replacement cost. In view of this, we propose an embedded tooth surface anti-loosening washer. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the existing technology, adapt to actual needs, and provide an embedded tooth surface anti-loosening washer to solve the technical problem that the gaskets of the current existing anti-loosening washers are often integrally formed, and the convex grooves or tooth surfaces on the gasket surface are easily worn after long-term use. If any of the convex grooves or tooth surfaces are worn, the gasket needs to be replaced as a whole, which increases the replacement cost.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is as follows: designing an embedded tooth surface anti-loosening washer, comprising a first washer piece, a second washer piece is meshed on the surface of the first washer piece, the first washer piece and the second washer piece have the same specifications, and a set of limit components are symmetrically provided inside the first washer piece and the second washer piece;

[0006] The first gasket sheet includes an outer ring, and a plurality of bevel teeth are evenly distributed on the surface of the outer ring. A convex plate is attached to the end of the outer ring away from the bevel teeth. An inner ring is fixed to the surface of the convex plate close to the outer ring. A group of guide grooves are symmetrically opened on the wall surface of the inner ring, and a guide block is engaged inside the guide groove.

[0007] Preferably, the outer ring and the plurality of helical teeth are integrally formed, and the inner ring is matched and engaged with the inner portion of the outer ring.

[0008] Preferably, the outer ring and the guide block are integrally formed, and the outer ring forms a locking structure through the guide block and the guide groove.

[0009] Preferably, the limiting assembly includes a spring, a group of the springs are symmetrically arranged on both sides of the inner ring, the ends of the springs are connected to a limiting block, the end of the limiting block away from the spring is fitted with a movable block, and a limiting groove is provided on the outside of the movable block.

[0010] Preferably, the limiting block forms an elastic structure with the inner ring through a spring, and the exposed portion of the limiting block is engaged with the inside of the outer ring.

[0011] Preferably, the limiting groove and the outer ring are integrally formed, and the movable pressing block can slide inside the limiting groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model designs the first gasket sheet and the second gasket sheet to be detachable, which is convenient for subsequent partial replacement and effectively reduces the replacement cost. The cooperation between the guide block and the guide groove facilitates the rapid assembly of the outer ring and the inner ring, and can accurately guide the limit assembly, thereby improving the assembly efficiency.

[0014] 2. In the present invention, the outer ring and the inner ring are assembled on the basis that the limiting block is integrally embedded in the inner ring. When the limiting block is flush with the limiting groove, the limiting block is partially popped out by the spring rebound force and effectively engaged with the inner ring, thereby quickly fixing the outer ring and the inner ring. During subsequent disassembly, the movable button is pressed inward to push the limiting block out of the outer ring. At this time, the inner ring and the embossed plate can fall directly under the influence of gravity and be quickly separated from the outer ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0024] An embedded tooth surface anti-loosening washer, see Figures 1 to 5 , comprising a first washer piece 1, a second washer piece 2 is engaged on the surface of the first washer piece 1, the first washer piece 1 and the second washer piece 2 have the same specifications, and a set of limiting components 3 are symmetrically provided inside the first washer piece 1 and the second washer piece 2;

[0025] The first gasket sheet 1 includes an outer ring 101, and a plurality of bevel teeth 102 are evenly distributed on the surface of the outer ring 101 in an annular shape. A convex plate 103 is attached to the end of the outer ring 101 away from the bevel teeth 102, and an inner ring 104 is fixed to the surface of the convex plate 103 on the side close to the outer ring 101, wherein the outer ring 101 and the plurality of bevel teeth 102 are integrally formed, and the inner ring 104 is matched and engaged with the inner part of the outer ring 101. A group of guide grooves 105 are symmetrically opened on the wall surface of the inner ring 104, and a guide block 106 is engaged with the inner part of the guide groove 105. Furthermore, the outer ring 101 and the guide block 106 are integrally formed, and the outer ring 101 forms a clamping structure with the guide groove 105 through the guide block 106. The utility model designs the first gasket sheet 1 and the second gasket sheet 2 to be detachable, which is convenient for subsequent partial replacement and effectively reduces the replacement cost. The cooperation between the guide block 106 and the guide groove 105 facilitates the rapid assembly of the outer ring 101 and the inner ring 104, and can accurately guide the limit assembly 3, thereby improving assembly efficiency.

[0026] It is worth noting that the limit assembly 3 includes a spring 301, a group of springs 301 are symmetrically arranged on both sides of the inner ring 104, and the ends of the springs 301 are connected to the limit blocks 302, wherein the limit blocks 302 form an elastic structure with the inner ring 104 through the springs 301, and the exposed part of the limit blocks 302 is engaged with the inner ring 101, and the end of the limit blocks 302 away from the spring 301 is affixed with a movable block 303, and a limit groove 304 is provided on the outside of the movable block 303. Furthermore, the limit groove 304 and the outer ring 101 are integrally formed, and the movable block 303 can slide inside the limit groove 304. When the limit block 302 is fully embedded in the inner ring 104, the outer ring 101 and the inner ring 104 are engaged and assembled. When the limit block 302 is flush with the limit groove 304, the limit block 302 is partially popped out and effectively engaged with the inner ring 101 under the influence of the rebound force of the spring 301, thereby quickly achieving the fixation between the outer ring 101 and the inner ring 104. During subsequent disassembly, the movable button 303 is pressed inward to push the limit block 302 out of the outer ring 101. At this time, the inner ring 104 and the embossed plate 103 can fall directly under the influence of gravity and be quickly separated from the outer ring 101.

[0027] When the locking cam 302 is aligned with the locking groove 304, the locking cam 302 is partially popped out and locked in the inner part of the outer ring 101 under the influence of the rebound force of the spring 301, thereby quickly achieving the fixation between the outer ring 101 and the inner ring 104.
