Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of anti-loosening washers, and in particular relates to a double-disc anti-loosening washer with a wear-resistant function. Background Art
[0002] The anti-loosening washer consists of two identical washers, each of which has a radial convex surface on the outside and a beveled surface on the inside. When installing, the inner beveled surfaces of the two washers are placed facing each other and placed between the nut and the connecting material.
[0003] When the existing anti-loosening washers are in use, wear occurs between the convex surface and the bevel tooth surface due to friction, thereby affecting the anti-loosening effect of the anti-loosening washers. Utility Model Content
[0004] The purpose of the utility model is to provide a double-disc anti-loosening washer with wear-resistant function to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a double-disc anti-loosening washer with wear-resistant function, comprising: a coaxial first washer and a second washer, a plurality of limit blocks are provided on the side opposite to each other of the first washer and the second washer, an adjustment mechanism for gap adjustment is provided between each of the limit blocks and the first washer or the second washer, each of the adjustment mechanisms comprises an elastic rod, the elastic rod is transversely embedded in the first washer or the second washer, and each of the limit blocks is respectively installed at one end of each elastic rod away from the first washer or the second washer.
[0006] Preferably, the ends of the first gasket and the second gasket facing away from each other are each provided with a plurality of receiving grooves in a ring array, and each of the elastic rods is respectively arranged in a corresponding receiving groove.
[0007] Preferably, a limiting ring for limiting positioning is provided between the first washer and the second washer, an inner toothed ring is provided on the inner side of the limiting ring, and outer toothed rings meshing with the inner toothed ring are provided on the outer walls of the first washer and the second washer.
[0008] Preferably, both ends of the limiting ring are provided with rubber pads for limiting the position, and the two rubber pads are respectively sleeved on the first washer and the second washer.
[0009] Preferably, the first washer and the second washer are both provided with coaxial through holes at their axis centers.
[0010] Preferably, each of the limiting blocks is provided with anti-slip teeth on a side facing away from the first washer or the second washer for preventing slipping.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] (1) The utility model adds a plurality of limit blocks and an adjusting mechanism. When the bolt is stretched due to vibration, the adjustment mechanism adjusts the gap between the limit block and the washer so that the limit block always abuts against the bolt, thereby locking the bolt and preventing it from loosening.
[0013] (2) The present invention provides an elastic rod connected to the limit block. The elastic bending of the elastic rod facilitates position adjustment when the limit block is subjected to force, so that the limit block always abuts against the bolt.
[0014] (3) The utility model adds a limiting ring, an inner gear ring and an outer gear ring. When the first washer and the second washer are subjected to force, the limiting ring is pressed down, so that the inner gear ring and the outer gear ring are engaged, thereby avoiding rotational sliding between the first washer and the second washer, and avoiding sliding wear between the first washer and the second washer.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] refer to Figure 1-2 As shown, the utility model provides a double-disc anti-loosening washer with wear-resistant function, including: a coaxial first washer 3 and a second washer 4, a plurality of limit blocks 7 are provided on the side opposite to each other of the first washer 3 and the second washer 4, and an adjustment mechanism for gap adjustment is provided between each limit block 7 and the first washer 3 or the second washer 4, and a coaxial through hole 5 is penetrated at the axis of the first washer 3 and the second washer 4, each adjustment mechanism includes an elastic rod 6, which is transversely embedded in the first washer 3 or the second washer 4, and each limit block 7 is respectively installed at the end of each elastic rod 6 away from the first washer 3 or the second washer 4.
[0021] As described above, when using the first washer 3, the second washer 4, the multiple limit blocks 7 and the multiple adjustment mechanisms provided by the present invention, after the first washer 3 and the second washer 4 are installed on the bolt through the through hole 5, the multiple elastic rods 6 drive the multiple limit blocks 7 to abut against the bolt and the force-bearing surface respectively. When the side of the bolt is long, the elastic rods 6 bend elastically so that the limit blocks 7 always abut against the bolt and the force-bearing surface, thereby preventing the first washer 3 and the second washer 4 from loosening.
[0022] Further, in order to facilitate the concealment of the elastic rod 6 in the first washer 3 and the second washer 4, refer to Figure 2-3 As shown, a plurality of receiving grooves 8 are formed in an annular array at the ends of the first and second washers 3 and 4, respectively, facing away from each other. Each elastic rod 6 is disposed in a corresponding receiving groove 8. The receiving grooves 8 conceal the elastic rods 6 within the first and second washers 3 and 4, preventing interference with the installation of the washers.
[0023] Further, in order to improve the anti-loosening effect of the limit block 7, refer to Figure 3 As shown, each limit block 7 is provided with anti-skid teeth 11 on one side away from the first washer 3 or the second washer 4. The anti-skid teeth 11 can increase the friction coefficient between the limit block 7 and the foreign object, thereby improving the anti-loosening effect of the equipment.
[0024] In this utility model, combined with Figure 1-3 As shown, a limiting ring 1 for limiting positioning is provided between the first washer 3 and the second washer 4 in this embodiment, an inner toothed ring 9 is provided on the inner side of the limiting ring 1, and an outer toothed ring 10 meshing with the inner toothed ring 9 is provided on the outer walls of the first washer 3 and the second washer 4.
[0025] As mentioned above, when using the limit ring 1 provided by the present invention, when the inner tooth ring 9 on the limit ring 1 engages with the outer tooth ring 10 on the first washer 3 and the second washer 4, the first washer 3 and the second washer 4 can be restricted in the limit ring 1 to prevent relative rotation between the first washer 3 and the second washer 4.
[0026] Furthermore, in order to prevent the limiting ring 1 from shaking between the first washer 3 and the second washer 4, refer to Figure 1-2 As shown, rubber pads 2 are provided at both ends of the retaining ring 1 for limiting the position. The two rubber pads 2 are respectively mounted on the first washer 3 and the second washer 4. When the bolt abuts against the washers, the two rubber pads 2 are compressed and fill the ends of the retaining ring 1, preventing the retaining ring 1 from shaking up and down, thereby preventing the retaining ring 1 from making abnormal noises.
[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
