Description

   Locking washer structure   

The invention relates to a structure of a lock washer, in particular to a plurality of anti-reverse bevel teeth which are provided on the front side of the washer with a low slope from the outside to the inside. The assembly further produces a better anti-reverse effect, and a plurality of positioning bevel teeth arranged opposite to the anti-reverse bevel teeth are arranged on the back of the washer, and each positioning bevel teeth has an arc edge for large area And it is firmly embedded and positioned in the workpiece, so that it can have a good anti-reverse locking effect.

According to our previous known and conventional lock washer structure, such as US patent number: US2010 / 0209214 A1, Taiwan patent number: I438349, application number: 097137443, the structure of the patent case is that the washer 2 has a separate A first side 4 and a second side 6 located on one of the front and the back and a middle hole 3 located in the center and penetrating through the first and second sides 4, 6 are provided, and the middle hole 3 can be passed by a bolt element. One side 4 has a serrated embossing 5 with a radius extension, the second side 6 has a cam embossing 7 with a radius extension, and the cam embossing 7 is opposite to the oblique direction of the fan-shaped ratchet on the zigzag embossing 5 .

However, the lack of the conventional lock washer structure lies in:

1. Please supplement as shown in Figure 5 of the US Patent Gazette. The scalloped ratchet teeth included in the serrated embossing 5 of the conventional washer 2 are flat teeth with the same height at the outer end and the inner end, so it is not easy. It is deeply embedded in the screwing part, and it is easy to cause the screwing part to slide, so the anti-reverse locking effect is poor.

2. As shown in Figure 5 of the U.S. Patent Bulletin, the fan-shaped ratchets in the zigzag embossing 5 are flat teeth with the same height at the outer end and the inner end. The contact area, in turn, will produce a large frictional force, so it will not only make the lock more laborious, but also easily cause abrasion.

3. Please supplement as shown in Figure 5 of the US Patent Gazette. The fan-shaped ratchet teeth included in the cam embossing 7 of the conventional washer 2 are flat teeth with the same height at the outer end and the inner end, so it is not easy. It is deeply embedded in the threaded member, so its engagement effect is not good, and the washer 2 is liable to slide due to this.

4. Please supplement with Figure 5 of the U.S. Patent Gazette. The fan-shaped ratchets in the cam embossing 7 have flat sides due to the sides of the upright surface, so they have poor engagement effect and have The problem of poor check-locking effect.

In view of the lack of the conventional locking washer structure, the inventor finally came to the market with a locking washer structure that can solve the shortcomings of the conventional industry by leveraging years of manufacturing, design and production experience in related industries.

The serrated embossing and cam embossing of the conventional locking washer structure is not easy to be deeply embedded in the screwed part and the screwed part or the workpiece, so that the effect of anti-reverse locking is poor, and the serrated embossed and screwed parts Large frictional force will be generated, which makes the screw lock more laborious and easy to wear. In the lock washer structure of the present invention, the washer uses a plurality of anti-reverse bevel teeth with a low slope from the front to the inside, which can make It can be easily inserted into the screwed part to produce a better anti-reverse effect. With a plurality of positioning bevel teeth with arc edges that are opposite to the positioning bevel teeth on the upper and rear sides, they can be firmly embedded and positioned on the screwed part. Has a good anti-reverse locking effect.

A washer structure for locking. The washer is ring-shaped, and has a plurality of fan-shaped non-reversing bevel teeth arranged radially and fan-shaped on the back, and a plurality of fan-shaped bevel teeth arranged radially and fan-shaped. Surface, the outer side has an outer peripheral surface, wherein: the plurality of anti-reverse bevel teeth are gradually inclined downward from the outer peripheral surface toward the inner peripheral surface, and each of the non-reverse bevel teeth includes a vertical surface and an inclined surface, and the non-reverse bevel teeth The oblique surface is inclined downwardly from the upper side of the non-reversing bevel tooth to the lower side of the adjacent non-reversing bevel tooth, so that a ratchet-like structure is formed. The height of the outer side is greater than the height of the inner side, and the slope of the non-reversing bevel tooth is inclined downward in a counterclockwise direction; the plurality of positioning bevel teeth include each elevation bevel and a bevel, The elevation surface of the positioning umbrella teeth is arc-shaped, and the inclined surface of the positioning umbrella teeth is inclined downward from the upper side of the positioning umbrella teeth to the lower side of the adjacent positioning umbrella teeth. So that a ratchet-like structure is formed, and the inclined surface of the positioning bevel is inclined low clockwise, the positioning Bevel teeth area larger than the area of the inclined surface of the bevel gears of the check, the height of the facade system positioned outside the bevel gears is not less than the height of the inner side edges.

The front side of the washer has a plurality of anti-reverse bevel teeth which are inclined from the outside to the inside. The outer end of the anti-reverse bevel teeth has a sharp angle that can be easily embedded in the screwing member, thereby generating a better anti-reverse effect. The back side of the washer has a plurality of positioning bevel teeth with an arc direction opposite to that of the non-reversing bevel teeth. It can be positioned in the screwed part with a large area and firm engagement, so that it can have a good stop. Reverse locking effect.

In order to fully understand the effects of the present invention by members of the Bureau and those skilled in the art, the structure and composition of the present invention are explained in conjunction with the drawings and figures, but the following are only used to explain the implementation of the present invention.

The advantages of the lock washer structure of the present invention are:

1. Please supplement as shown in the first and second figures. The plurality of non-reversing bevel teeth 11 are gradually inclined from the outside to the inside, that is, the height 113 of the outer side of the facade 111 is greater than the height 114 of the inner side. The outer end of the anti-reverse bevel tooth 11 will form a sharp angle, and can be easily inserted into the head of the screwing member (such as a bolt), thereby generating a better anti-reverse locking effect.

2. Please supplement as shown in the first and second figures. The multiple non-reversing bevel teeth 11 of the washer 10 are in the shape of bevel teeth with high outside and low inside, so they have a small contact area with the screwed parts. The locking between the two can sometimes reduce the generation of frictional force, so it can save labor when screwing, and can also reduce the generation of wear.

3. Please supplement as shown in the third and fourth figures. The plural positioning bevel teeth 12 are gradually inclined from the outside to the inside (that is, the height 124 on the outer side of the facade 121 is greater than the height 123 on the inner side). The outer end of the umbrella tooth 12 will form a sharp angle, and can be easily embedded in the surface of the screwed part or the workpiece, thereby generating a better positioning and locking effect.

4. Please supplement as shown in the third and fourth figures. The elevation 121 of the plurality of positioning bevel teeth 12 of the washer 10 is arc-shaped, so it is possible to increase the embedding of the threaded part or the workpiece. Area, so that it has a better engagement effect, so it can further improve its anti-reverse locking effect and prevent the washer 10 from loosening.

Therefore, the lock washer structure of the present invention has industrial applicability, novelty, and progressability, and can meet the application requirements of the invention patent, and is submitted in accordance with the law.
