[0024] Embodiment one:

[0025] Please refer to Figures 1 to 4As shown, the automobile brake bottom plate support structure improvement device, including brake bottom plate 1, the inside of brake bottom plate 1 is provided with blocking cover 2, one side of blocking cover 2 is fixedly connected with adjusting cavity 3, adjusting cavity 3 is rotatably provided with adjusting rod 4 in the inside, the bottom end of adjusting rod 4 is fixedly connected with first bevel gear 5, the surface of first bevel gear 5 is engaged with three second bevel gears 6, the inside of second bevel gear 6 is fixedly connected with threaded rod 7, and the top end of threaded rod 7 is rotatably arranged in the inside of adjusting cavity 3, the surface of threaded rod 7 is threadedly penetrated by threaded sleeve 8, the surface of threaded sleeve 8 is fixedly connected with plug-in rod 9, and the surface of plug-in rod 9 is penetrated in the inside of blocking cover 2. By the setting of blocking cover 2, the brake drum can be blocked after being put into the inside of brake bottom plate 1, by the setting of adjusting cavity 3, adjusting rod 4 is rotatably arranged in the inside, by the setting of first bevel gear 5, three second bevel gears 6 are rotatable, it should be noted that three second bevel gears 6 are arranged one above the other and then one on the right side, by the setting of threaded rod 7, second bevel gear 6 is rotatable, and threaded sleeve 8 is moved up and down, and plug-in rod 9 is moved up and down.

[0026] Five heat dissipation holes 10 are formed in the inside of blocking cover 2, and a placing groove 11 is formed in the inside of brake bottom plate 1. By the formation of heat dissipation holes 10, external air can enter the inside of brake bottom plate 1 and cool it down when in use, and by the formation of placing groove 11, the brake drum has a certain installation space.

[0027] Three plug-in holes 12 are formed in the inside of brake bottom plate 1, and the surface of plug-in rod 9 is penetrated in the inside of plug-in hole 12. By the formation of plug-in hole 12, plug-in rod 9 is penetrated in the inside, and blocking cover 2 is fixed in the inside of brake bottom plate 1.

[0028] Example two:

[0029] Please refer to Figure 1 , Figure 2 and Figure 5 As shown, one side of adjusting cavity 3 is fixedly connected with connecting ring 13, the surface of connecting ring 13 is threadedly connected with protective cover 14, one side of protective cover 14 is fixedly connected with sleeve pipe 15, pull rod 16 is penetrated in the inside of sleeve pipe 15, and the surface of pull rod 16 is penetrated in the inside of protective cover 14, the bottom end of pull rod 16 is fixedly connected with plug-in block 17. By the setting of connecting ring 13, protective cover 14 is connected with it, which protects adjusting rod 4 to a certain extent, by the setting of protective cover 14, sleeve pipe 15 is fixedly installed, by the setting of pull rod 16, plug-in block 17 is linked with it.

[0030] The inner wall of the protective cover 14 is slidably connected to a partition 18, and the surface of the pull rod 16 passes through and is fixed inside the partition 18.

[0031] A compression spring 19 is fixedly connected to the middle of one side of the partition 18, and the end of the compression spring 19 away from the partition 18 is fixedly connected to the inner wall of the protective cover 14. The partition 18 makes it easy for the compression spring 19 to be squeezed later. The compression spring 19 also allows the plug block 17 and the partition 18 to automatically reset after moving to the right a certain distance.

[0032] The adjusting rod 4 has a square groove 20 inside, and the plug block 17 passes through the inside of the square groove 20. The square groove 20 allows the plug block 17 to be inserted into it. It should be noted that the size of the plug block 17 matches the size of the square groove 20.

[0033] The working principle of this utility model is as follows: The operator first places the brake drum into the placement groove 11 inside the brake base plate 1, then places the blocking cover 2 inside the brake base plate 1. Simultaneously, the operator rotates the adjusting rod 4. As the adjusting rod 4 rotates, it drives the first bevel gear 5 to rotate counterclockwise. The rotation of the first bevel gear 5 drives the three second bevel gears 6 to rotate, which in turn causes the threaded rod 7 inside the second bevel gear 6 to rotate. This causes the threaded rod 7 to drive the threaded sleeve 8 on its surface to move downwards. Then, the insertion rod 9 moves to the opposite position, facilitating the entry of the blocking cover 2 into the brake base plate 1. Once the blocking cover 2 is fully inside the brake base plate 1, and the position of the insertion rod 9 on the blocking cover 2 corresponds to the position of the insertion hole 12 on the brake base plate 1, the operator then rotates the adjusting rod 4 clockwise. This causes the threaded rod 7 to reverse, which in turn causes the threaded sleeve 8 to move the plug rod 9 in a disjointed direction until it is inserted into the plug hole 12. Finally, the blocking cover 2 is fixed inside the brake base plate 1. Then, the operator pulls the pull rod 16 to the right, which causes the pull rod 16 to move the partition 18 to the right, which then compresses the compression spring 19. At this time, the operator rotates the protective cover 14 to make it threadedly connected to the connecting ring 13. Then, the operator stops pulling the pull rod 16, and the compression spring 19 returns to its original position, which in turn causes the partition 18 and the plug block 17 to return to their original positions. After the plug block 17 returns to its original position, it is inserted into the square groove 20, which fixes the adjusting rod 4 and prevents the adjusting rod 4 from rotating accidentally during use, which could cause the plug rod 9 to fall out of the plug hole 12.

[0034] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
