[0031] The present utility model provides a locking washer, which mainly tightens the side wall of the fixed bolt by means of the deformation of the first arc section and the second arc section on the first gasket and the second gasket, improving the fixing effect and being simple and convenient to use.

[0032] The following will detail a locking washer of the present application through the following embodiments.

[0033] In this embodiment, as Figure 1 and Figure 2 shown, the locking washer includes: a first gasket 1 and a second gasket 2. Both the first gasket 1 and the second gasket 2 are circularly symmetric structures. The first gasket 1 and the second gasket 2 are symmetrically arranged and fixed to each other. The first gasket 1 is provided with a first arc section 101, and the second gasket 2 is provided with a second arc section 201. The first arc section 101 and the second arc section 201 face each other, and there is a gap between the first arc section 101 and the second arc section 201. A third gasket 3 is clamped in the gap. The inner diameter of the third gasket 3 is smaller than the inner diameters of the first gasket 1 and the second gasket 2, and the outer diameter of the third gasket 3 is larger than the inner diameters of the first gasket 1 and the second gasket 2.

[0034] In this technical solution, both the first gasket 1 and the second gasket 2 have a circumferentially symmetric structure. Both the first gasket 1 and the second gasket 2 are hollow and are sleeved on the bolt to be acted on. The first gasket 1 is placed on the upper side of the second gasket 2. The first gasket 1 and the second gasket 2 are symmetrically arranged with respect to the horizontal plane. The center of the first arc segment 101 faces downward, and the center of the second arc segment 201 faces downward. The first arc segment 101 is connected to the first fixed segment 103 through the first connecting segment 102. The second arc segment 201 is connected to the second fixed segment 203 through the second connecting segment 202. The first gasket 1 and the second gasket 2 are connected through the first fixed segment 103 and the second fixed segment 203. There is a certain distance between the first arc segment 101 and the second arc segment 201 to form a gap, and the inner sides of the first arc segment 101 and the second arc segment 201 are open, facilitating the subsequent clamping of the third gasket 3 on both the inner and outer sides of the opening.

[0035] In this embodiment, the first gasket 1 and the second gasket 2 are made of hard materials, and the third gasket 3 is made of flexible materials.

[0036] In this technical solution, the first gasket 1 and the second gasket 2 are made of iron or steel materials, and the third gasket 3 is made of rubber or plastic materials. Such a setting enables the third gasket 3 to completely fit the surface of the bolt and maintain the fitting state under the acting force after the deformation of the first arc segment 101 and the second arc segment 201, improving the fixing effect between the lock washer and the bolt.

[0037] In this embodiment, the first gasket 1 is provided with a first connecting segment 102 and a first fixed segment 103, and the second gasket 2 is provided with a second connecting segment 202 and a second fixed segment 203. The first fixed segment 103 is arranged on the outer side of the first arc segment 101, and the second fixed segment 203 is arranged on the outer side of the second arc segment 201. The first connecting segment 102 is respectively connected to the first fixed segment 103 and the first arc segment 101, and the second connecting segment 202 is respectively connected to the second fixed segment 203 and the second arc segment 201.

[0038] In this technical solution, the cross-section of the first connecting segment 102 is arc-shaped, and the center of the arc of the first connecting segment 102 faces upward. The cross-section of the second connecting segment 202 is arc-shaped, and the center of the arc of the second connecting segment 202 faces downward. The cross-sections of the first fixed segment 103 and the second fixed segment 203 are both rectangular. The first connecting segment 102, the second connecting segment 202, the first fixed segment 103, and the second fixed segment 203 are provided to extend the first arc segment 101 and the second arc segment 201, reducing the resistance when the first gasket 1 and the second gasket 2 are squeezed towards the middle and reducing the processing difficulty of the first gasket 1 and the second gasket 2.

[0039] In this embodiment, several first convex stripes 104 are provided on the side of the first fixed segment 103 close to the second fixed segment 203;

[0040] And / or, several second ridges 204 are provided on the side of the second fixing section 203 close to the side of the first fixing section 103;

[0041] And / or, clamping grooves 105 for clamping each of the first ridges 104 and / or each of the second ridges 204 are respectively provided on the mutually adjacent sides of the first fixing section 103 and the second fixing section 203.

[0042] In this technical solution, since the first gasket 1 and the second gasket 2 are plane-symmetrical structures, the first gasket 1 and the second gasket 2 can be respectively formed by stamping during production. At the same time, structures corresponding to the first ridges 104, the second ridges 204, and the clamping grooves 105 are provided on the stamping die during stamping, and finally the first gasket 1 and the second gasket 2 are combined together by extrusion. A plurality of first ridges 104 and clamping grooves 105 corresponding to the second ridges 204 are uniformly arranged on the lower circumference of the first fixing section 103 of the first gasket 1, and a plurality of second ridges 204 and clamping grooves 105 corresponding to the first ridges 104 are uniformly arranged on the upper side circumference of the second fixing section 203 of the second gasket 2, which can improve the fixing effect when the first gasket 1 and the second gasket 2 are extruded and fitted together.

[0043] In this embodiment, the first ridges 104 and / or the second ridges 204 are inclined radially with respect to the first gasket 1.

[0044] In this technical solution, the first ridges 104, the second ridges 204, and the clamping grooves 105 corresponding to both of them are all set to be strip-shaped, and are inclined radially with respect to the first gasket 1 or the second gasket 2. In this way, it can increase the difficulty of the locking washer expanding outwards when being compressed and deformed, and prompt the locking washer to deform inwards.

[0045] In this embodiment, a first friction pattern 106 is provided on the side of the first arc section 101 away from the second arc section 201;

[0046] And / or, a second friction pattern 205 is provided on the side of the second arc section 201 away from the first arc section 101.

[0047] In this technical solution, a plurality of first friction patterns 106 are uniformly arranged on the upper circumference of the first arc section 101, and a plurality of second friction patterns 205 are uniformly arranged on the lower side circumference of the second arc section 201. The first friction patterns 106 and the second friction patterns 205 are strip-shaped protrusions provided on the surface. The provision of the first friction patterns 106 and the second friction patterns 205 can increase the surface friction between the locking washer and the object to be fixed and the nut, and improve the fixing effect.

Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles of the embodiments, the practical application, or the improvement of the technology in the market, or to enable other ordinary technical personnel in the technical field to understand the embodiments disclosed herein.
