DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1: This embodiment is intended to solve the problem that in the prior art, most friction discs are fixed and installed by bolts. When used for a long time, the friction disc may be inconvenient to disassemble due to the smear of oil and dust. Figure 1-Figure 4A friction disc structure of a motor vehicle grounding device includes a friction disc body 110 and a connecting disc 120. The connecting disc 120 is fixedly installed in the middle of the friction disc body 110, and a fixing column 130 is inserted in the middle of the connecting disc 120. A clamping ring 140 is sleeved on the side of the fixing column 130. The fixing column 130 is clamped and fixed by a clamping assembly 330 in the middle of the clamping ring 140. A clamping groove 150 is opened in the middle of the clamping ring 140. A baffle 170 is connected to the side of the clamping groove 150. The baffle 170 is clamped and connected with the mounting block 250 through a clamping assembly 270.

[0023] A rack 260 is fixedly installed on the side of the mounting block 250, and a plurality of engaging grooves 280 are opened on the side of the rack 260. The engaging assembly 270 includes a gear 300 meshing with the rack 260, and a rotating shaft 290 is hinged in the middle of the gear 300. A fixed block 160 is fixedly connected to the side of the clamping groove 150, and the fixed block 160 is fixedly connected to the mounting block 250. The clamping assembly 330 includes a push block 180 fixedly connected to the baffle 170, and a mounting groove 210 is opened on the side of the push block 180, and a spring 220 is installed in the middle of the mounting groove 210.

[0024] When the friction disc needs to be disassembled, the staff can directly pull the friction disc out of the fixing column 130. When installation is required, the staff first plugs the friction disc into the side of the fixing column 130. Then, due to the small diameter of the clamping groove 150, the baffle 170 will push the push block 180 to squeeze the spring 220 during insertion. At the same time, due to the movement of the baffle 170, the gear 300 on the side of the baffle 170 will move on the rack 260. Since the size of the fixing column 130 is designed according to regulations, when the insertion stops, the gear 300 will engage with the engaging groove 280 and can be installed.

[0025] In this embodiment: through the setting of the clamping assembly 330, when disassembling the friction disc, the staff can directly pull out the fixing column 130. This method does not require the use of bolts for fixing, so it is more convenient during the disassembly process. After the disassembly is completed, due to the setting of the spring 220, the baffle 170 will be reset. The clamping assembly 330 can be reused, which solves the problem that most of the friction discs mentioned in the above background technology are fixed and installed by bolts. When used for a long time, it may be inconvenient to disassemble the friction disc due to the smear of engine oil and dust, thereby greatly improving the practicality of the structure.

[0026] Embodiment 2: This embodiment is intended to promote the solution of the problem in the prior art that when different mounting shafts are used to install the friction disc, the fixing method needs to be changed according to the current situation, which will affect the work efficiency of the staff during the installation process. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 4 One end of the spring 220 is fixedly connected to the inner wall of the mounting groove 210 , and the other end of the spring 220 is fixedly connected to a push plate 230 , and a limiting rod 190 is inserted into the side of the push plate 230 .

[0027] A connecting plate 200 is fixedly installed at the bottom of the limiting rod 190, a slot 240 is opened on the side of the push plate 230, and slots 240 are opened on both sides of the push plate 230. The slots 240 are intermittently engaged with the connecting plate 200. A reinforcing plate 310 is fixedly connected to the side of the push block 180, and a reinforcing rod 320 is fixedly installed on the side of the reinforcing plate 310. The reinforcing rod 320 limits the baffle 170. The clamping assemblies 330 are symmetrically arranged with the clamping groove 150 as the central axis, and the two clamping assemblies 330 are arranged in a vertical state.

[0028] In this embodiment: through the mutual cooperation between the clamping assembly 330 and the engaging assembly 270, when the friction disc is installed, the friction disc can be fixed without using bolts. When installing, the staff can directly insert the friction disc into the side of the fixing column 130 through the clamping ring 140. During the insertion process, due to the small diameter of the clamping groove 150, the baffle 170 will be pushed. When the baffle 170 moves, it will drive the gear 300 to rotate. At this time, there is no external force, the friction disc will stop moving, and the gear 300 will engage with the engaging groove 280 to be fixed. Through the cooperation of a series of structures, it is easier for the staff to install the friction disc, thereby improving the work efficiency of the staff.

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
