DETAILED DESCRIPTION

[0024] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0025] A dust cover with a pressing spring on the inner diameter of a bearing according to an embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

[0026] Example 1

[0027] For easier understanding, see Figures 1 to 5 The utility model provides an embodiment of a dust cover with a pressing spring on the inner diameter of a bearing, comprising a cover body 2, a limit block 3 fixedly connected to the inner side of the cover body 2, a bearing body 1 is arranged on the inner side of one end of the cover body 2, a dustproof net cover 4 is arranged at one end of the cover body 2, and a pressing spring quick-release fixing assembly is arranged between the cover body 2 and the bearing body 1;

[0028] The pressing spring quick-release fixing assembly includes a movable groove 501, a fixing pin 502, a return spring 503, a first fixing groove 504, a second fixing groove 505 and a fixing steel ring 506. The movable groove 501 is arranged on the inner side of one end of the cover body 2, the fixing pin 502 is slidably connected to the inner side of the movable groove 501, the return spring 503 is sleeved on the outer wall of the fixing pin 502, the first fixing groove 504 is arranged on the outer side of the bearing body 1, the second fixing groove 505 is arranged on the outer side of one end of the cover body 2, the fixing steel ring 506 is fixedly installed on the inner side of the second fixing groove 505, one end of the return spring 503 is fixed to one end of the fixing pin 502, and the other end of the return spring 503 is abutted against the inner end surface of the movable groove 501, one end of the fixing pin 502 is abutted against the inner side of the first fixing groove 504, and the inner surface of the fixing steel ring 506 is abutted against the surface of one end of the fixing pin 502.

[0029] It should be noted that, by providing a fixing pin 502 and a return spring 503, and opening a first fixing groove 504 on the bearing body 1, the fixing steel ring 506 is sleeved in the second fixing groove 505, and the fixing steel ring 506 is used to limit the fixing pin 502, so that the fixing pin 502 overcomes the elastic force of the return spring 503 and inserts one end into the first fixing groove 504, so that the bearing body 1 can be fixed in the cover body 2 to prevent the bearing body 1 from falling off. When the fixing steel ring 506 is removed, the return spring 503 lifts the fixing pin 502 to disengage it from the first fixing groove 504. At this time, the bearing body 1 can be easily removed, thereby facilitating the loading and unloading of the bearing.

[0030] In some embodiments, Figure 4 As shown, one side surface of the bearing body 1 is abutted against one side surface of the limit block 3 .

[0031] It should be noted that the role of providing the limit block 3 is to limit the bearing body 1 when the bearing body 1 is installed.

[0032] Example 2

[0033] In some embodiments, Figure 4 As shown, a fixed joint 402 is fixedly connected to one end of the cover body 2, and a plurality of anti-skid grooves 401 are opened on the outside of the dustproof net cover 4. The anti-skid grooves 401 are arranged in a circular array on the outside of the dustproof net cover 4, and a threaded connection is adopted between the fixed joint 402 and the dustproof net cover 4.

[0034] It should be noted that the dustproof mesh cover 4 is connected by threads and a fixed joint 402, and the dustproof mesh cover 4 can be disassembled separately, so as to facilitate the disassembly and cleaning of the dustproof mesh cover 4 after long-term use. The anti-slip groove 401 is used to facilitate the rotation of the dustproof mesh cover 4.

[0035] Working principle: When in use, install the bearing body 1 on the inner side of one end of the cover body 2, and make one side surface of the bearing body 1 rest against one side surface of the limit block 3, install the bearing body 1 in place, and then put the set fixed steel ring 506 into the second fixed groove 505, and use the fixed steel ring 506 to limit the fixed pin 502, so that the fixed pin 502 overcomes the elastic force of the reset spring 503 and inserts one end into the first fixed groove 504, so that the bearing body 1 can be fixed in the cover body 2 to prevent the bearing body 1 from falling off. When the fixed steel ring 506 is removed, the reset spring 503 will lift the fixed pin 502 to disengage it from the first fixed groove 504. At this time, the bearing body 1 can be easily removed, thereby facilitating the loading and unloading of the bearing. Then, after using it for a period of time, the dustproof net cover 4 can be disassembled and cleaned separately.

[0036] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
