Description

Technical Field

[0001] The utility model belongs to the technical field of fasteners, and in particular relates to a combined washer. Background Art

[0002] A washer is a component placed between a connected part and a nut. It's typically a flat metal ring used to protect the surface of the connected part from scratches by the nut and to distribute the pressure exerted by the nut on the connected part. Types of washers include copper-coated asbestos washers, paper washers, flat washers, copper flat washers, spring washers, rubber washers, and more. Washers play a significant role and are commonly used in daily life. The key is to distinguish which washers to use where. From small washers for screw nuts to large washers for large metal boxes to prevent wear, there are many types. The quality of washers affects the stability and safety of equipment, so even small washers are very important. In the related art, existing bolts generally use two double washers of the same structure to prevent loosening. Currently, workers simply put the two washers together for use. While this meets the requirements, the two washers are not positioned relative to each other during use. Therefore, when tightening the nut to tighten the bolt, especially when the washer hole is larger than the bolt diameter, the position of the washers can easily shift, resulting in a poor connection.

[0003] The Chinese utility model patent with publication number CN219774577U discloses a combined anti-loosening washer. The first washer and the second washer are engaged by the engagement protrusion and the engagement channel. Under the mutual attraction of the first magnetic ring and the second magnetic ring, the first washer and the second washer are connected as a whole, so that they are positioned relative to each other, and the two washers are prevented from sliding and offsetting each other when the nut is tightened, thereby achieving better fastening effect and better loosening, and thus better vibration resistance and anti-loosening, which is conducive to long-term use. At the same time, the first magnetic block and the second magnetic block can be attracted to the external machine surface and the nut respectively, thereby further improving the fastening effect. However, there are some other problems with this washer. For example, the height of the washer cannot be adjusted, which results in the combined washer easily leaving a gap or insufficient space for installation during installation, resulting in the need to replace the combined washer.

[0025] like Figure 1-Figure 3 As shown, this embodiment provides a combined gasket, comprising:

[0026] A first washer 100, wherein two symmetrical mounting grooves 110 are formed on the upper surface of the first washer 100;

[0027] The second gasket 200 is disposed above the first gasket 100 , and two connecting blocks 210 are provided on the lower surface of the second gasket 200 ;

[0028] The heightening plate 300 is disposed between the first washer 100 and the second washer 200 , and a through slot 310 is formed on the heightening plate 300 . The shape of the through slot 310 matches the shape of the connecting block 210 .

[0029] The lower surface of the first washer 100 and the upper surface of the second washer 200 are provided with anti-slip grooves 120 , and the connecting block 210 passes through the through groove 310 and is installed into the interior of the installation groove 110 .

[0030] In the present technical solution, in order to facilitate changing the height of the gasket according to different needs, two symmetrical mounting grooves 110 are provided on the upper surface of the first gasket 100, a second gasket 200 is provided above the first gasket 100, and two connecting blocks 210 are provided on the lower surface of the second gasket 200. The connecting blocks 210 can be installed in the interior of the mounting grooves 110. A heightening piece 300 can be provided between the first gasket 100 and the second gasket 200. Two through slots 310 are provided on the heightening piece 300. The shape of the through slots 310 is similar to that of the connecting blocks 210. 10 is consistent with the shape of the second gasket 200, so that the connecting block 210 under the second gasket 200 can be installed in the installation groove 110 of the first gasket 100 through the through groove 310 of the height-increasing plate 300. In this way, the height-increasing plate 300 can be set between the first gasket 100 and the second gasket 200, thereby achieving the effect of increasing the height of the gasket and making the gasket as a whole adaptable to the needs of different thicknesses. At the same time, anti-slip grooves 120 are respectively provided on the lower surface of the first gasket 100 and the upper surface of the second gasket 200, thereby preventing the gasket from slipping with the matching installation holes and parts.

[0031] This embodiment provides a combined gasket, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0032] like Figure 1-Figure 3 As shown, in this embodiment, a limiting groove 130 is transversely defined inside the installation groove 110 , and the inner walls of the limiting groove 130 are respectively slidably fitted with the outer walls of the connecting block 210 .

[0033] In this technical solution, in order to facilitate the connection block 210 to be fixed in the installation groove 110, a limiting groove 130 is opened inside the installation groove 110, so that the connection block 210 can be slid into the limiting groove 130 through the installation groove 110, thereby limiting the first gasket 100 and the second gasket 200.

[0034] This embodiment provides a combined gasket, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0035] like Figure 1 and Figure 2 As shown, in this embodiment, two springs 140 are transversely arranged inside the limiting groove 130, and a baffle 150 is provided on the side where the two springs 140 are close to each other.

When one end of the connecting block 210 is inserted into the inside of the installation groove 110, it contacts the baffle 150, causing the spring 140 to deform and then the other end of the connecting block 210 is installed into the other side of the sliding groove, so that the connecting block 210 is limited between the two baffles 150. Through the contact of the two springs 140 with the two baffles 150, the connecting block 210 can be limited inside the limiting groove 130.

[0037] This embodiment provides a combined gasket, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0038] like Figure 1-Figure 3 As shown, in this embodiment, the connecting block 210 is fixed to the lower surface of the second washer 200 through the adjusting rod 220 .

[0039] In the present technical solution, in order to ensure that the connecting block 210 can be installed in the mounting groove 110 of the first gasket 100 when the number of the height-increasing pieces 300 increases, the connecting block 210 is fixed to the lower surface of the second gasket 200 through the adjusting rod 220. By adjusting the length of the adjusting rod 220 according to the number of height-increasing pieces 300, it is ensured that the connecting block 210 can be installed in the interior of the mounting groove 110 while the height-increasing pieces 300 are mounted on the adjusting rod 220, thereby limiting the height-increasing pieces 300.

[0040] This embodiment provides a combined gasket, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0041] like Figure 1-Figure 3 As shown, in this embodiment, the adjustment rod 220 is configured as a rotatable stud.

[0045] In the present technical solution, in order to facilitate the mutual limiting and fixing between the first washer 100, the second washer 200 and the height increasing piece 300, two limiting holes 160 are further provided on the first washer 100, and the limiting holes 160 are designed in a "convex" shape. A penetrating circular hole 320 is also provided at the same position on the height increasing piece 300. The lower surface of the second washer 200 is provided with two limiting rods 230 corresponding to the positions of the limiting holes 160 and the circular hole 320. A fixing device 230 is fixed at the lower end of the limiting rod 230. There is a spherical block 240, the diameter of which is set to be larger than the diameter of the limiting rod 230. The diameter of the limiting rod 230 is set to be the same as the diameter of the limiting hole 160 in contact with the upper surface of the first washer 100. The diameter of the spherical block 240 is set to be the same as the diameter of the limiting hole 160 inside the first washer 100. At the same time, all of the above parts are made of elastic rubber, so that a larger diameter part can be installed into a smaller hole without damaging the part.

[0046] This embodiment provides a combined gasket, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0047] like Figure 1-Figure 3 As shown, in this embodiment, the width of the connecting block 210 is the same as the width of the mounting groove 110 , and the length of the connecting block 210 is greater than the length of the mounting groove 110 .

[0048] In this technical solution, in order to prevent the connecting block 210 from falling out of the limiting groove 130, the width of the connecting block 210 is set to be the same as the width of the installation groove 110, and the length of the connecting block 210 is set to be longer than the length of the connecting block 210. In this way, the connecting block 210 can be limited in the limiting groove 130 inside the installation groove 110. Because the connecting block 210 is made of elastic rubber material, it is convenient to install the larger connecting block 210 into the smaller installation groove 110.

[0049] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
