[0002] A brake clearance adjusting arm (referred to as an adjusting arm for short) is a part related to the brake system, which is used to adjust the clearance between the brake shoe and the brake disc to ensure the normal operation and safety performance of the brake system. The adjusting arm is usually installed in the brake system of an automobile and is connected to the brake piston and the brake shoe. The correct operation of the adjusting arm is one of the important components to ensure the normal operation of the brake system and improve driving safety. Regular inspection and maintenance of the brake adjusting arm are the keys to maintaining the good working condition of the brake system to ensure that the vehicle can brake in a timely and effective manner and avoid the risk of brake failure. When the existing adjusting arm is in use, the adjusting nut therein will become loose due to frequent brake vibrations, which will affect the braking accuracy. At the same time, due to the position where the adjusting arm is located, after the adjusting arm is used for a long time, there will be more stains on the surface, which will affect the braking accuracy and the difficulty of maintenance. Content of the Utility Model

[0003] The purpose of the utility model is to provide an adjusting arm with a dust-proof structure to solve the above problems. The connecting handle and the part at the joint of the adjusting arm body are sealed and protected by a sealing mechanism to reduce stains. At the same time, the adjusting arm body is wrapped by a sealing ring, which not only reduces stains but also makes the maintenance simpler and more convenient.

[0004] The utility model realizes the above purpose through the following technical solutions:

[0005] An adjusting arm with a dust-proof structure includes: a connecting handle and a sealing mechanism. The sealing mechanism is arranged on the front and rear sides of the bottom end of the connecting handle, and the sealing mechanism surrounds the connecting handle on three sides.

[0006] The sealing mechanism includes a sealing rotating plate and a rotating shaft. The rotating shaft penetrates through the sealing rotating plate and the connecting handle. Adjusting nuts are fixedly arranged at the front and rear ends of the shaft body of the rotating shaft, and a gear disc is fixedly arranged at the front of the shaft body of the rotating shaft.

[0007] Further, a rack groove is formed on the front side of the sealing rotating plate, a sliding plate is slidably arranged on one side of the sealing rotating plate, and a fixed damping groove is fixedly arranged on the side of the sliding plate close to the connecting handle.

[0008] Further, an adjusting arm body is fixedly arranged on the bottom side of the connecting handle, and an adjusting nut is rotatably arranged on one side of the adjusting arm body.

[0009] Further, sealing rings are detachably arranged on the front and rear sides of the adjusting arm body. The sealing rings include two fixing rings, and connecting rods are arranged on the outer sides of the two fixing rings.

[0010] Further, a rotating disc is rotatably arranged inside the fixing ring. An internal rack is fixedly arranged inside the rotating disc, and fixing grooves are penetratingly arranged on the surface of the rotating disc.

[0011] Further, the front and rear widths of the rotating disc exceed those of the fixing ring, and the front and rear widths of the internal rack are smaller than those of the rotating disc.

[0025] To make the purpose, technical solutions and advantages of the present invention clearer, the following will describe the technical solutions of the present invention in detail. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present invention.

[0026] See Figures 1-5 As shown, the present invention provides an adjusting arm with a dust-proof structure, including: a connecting handle 1 and a sealing mechanism 2. The sealing mechanism 2 is arranged on the front and rear sides of the bottom end of the connecting handle 1, and the sealing mechanism 2 surrounds the connecting handle 1 on three sides;

[0027] The sealing mechanism 2 includes a sealing rotating plate 201 and a rotating shaft 205. The rotating shaft 205 passes through the sealing rotating plate 201 and the connecting handle 1. Adjusting nuts 207 are fixedly arranged at the front and rear ends of the shaft body of the rotating shaft 205. And a gear disc 206 is fixedly arranged at the front of the shaft body of the rotating shaft 205. The rack in the gear disc 206 protrudes backward for a certain distance, which is more convenient for engaging with the rack groove 204. The gear disc 206 can perform a longitudinal displacement for a certain distance on the shaft body of the rotating shaft 205 to facilitate the subsequent staff to engage the gear disc 206 into the interior of the rack groove 204. And while adjusting the rotation of the rotating shaft 205, the adjusting nut 207 can also limit the gear disc 206 to prevent the gear disc 206 from slipping off the shaft body of the rotating shaft 205.

[0028] Further, a rack groove 204 is formed on the front side of the sealing rotating plate 201. The rack groove 204 can be engaged with the rack in the gear disc 206 to prevent the gear disc 206 from rotating. A sliding plate 202 is slidably arranged on one side of the sealing rotating plate 201. A fixed damping groove 203 is fixedly arranged on the side of the sliding plate 202 close to the connecting handle 1. The fixed damping groove 203 is driven by the sliding plate 202 to slide. And the inner teeth of the fixed damping groove 203 are provided with a relatively high damping, which can be sleeved with the adjusting nut 4 to limit the adjusting nut 4 and prevent the adjusting nut 4 from loosening due to the vibration of the adjusting arm body 5, reducing the braking accuracy.

[0029] Further, an adjusting arm body 5 is fixedly arranged on the bottom side of the connecting handle 1. An adjusting nut 4 is rotatably arranged on one side of the adjusting arm body 5. The adjusting nut 4 is engaged with the fixed damping groove 203 in the sealing mechanism 2. The fixed damping groove 203 itself limits the adjusting nut 4, and the firmness of the engagement between the fixed damping groove 203 and the adjusting nut 4 is increased through the damping.

[0030] Further, sealing rings 3 are detachably arranged on the front and rear sides of the adjusting arm body 5. The sealing ring 3 includes two fixing rings 301. Connecting rods 305 are arranged on the outer sides of the two fixing rings 301. The connecting rods 305 connect the fixing rings 301 to make the installation of the fixing rings 301 more convenient. And the connecting rods 305 are C-shaped. Both the fixing rings and the connecting rods 305 in the sealing ring 3 are made of aluminum alloy to reduce the overall weight of the adjusting arm.

[0031] Further, a rotating disk 303 is rotatably arranged inside the fixed ring 301. An internal rack 304 is fixedly arranged inside the rotating disk 303. A fixing groove 302 penetrates through the surface of the rotating disk 303. After the adjusting arm is put into use, the turbine in the adjusting arm body 5 and the internal rack 304 in the rotating disk 303 are simultaneously connected to the braking system. The internal rack 304 and the rotating disk 303 separate the adjusting arm body 5 from the outside, keeping the inside of the adjusting arm body 5 clean. For maintenance, only the sealing ring 3 needs to be removed for maintenance, making the maintenance simple and convenient.

[0032] Further, the front and rear width of the rotating disk 303 exceeds that of the fixed ring 301, providing a larger protection range. The front and rear width of the internal rack 304 is smaller than that of the rotating disk 303.

[0033] Further, one side of the sealing rotating plate 201 is flush with the connecting handle 1, and its top side is higher than the bottom side platform of the connecting handle 1. The sealing rotating plate 201 surrounds the bottom side of the connecting handle 1 on three sides. The non-surrounded side is flush with the connecting handle 1, making it more convenient for the sealing rotating plate 201 to rotate and lift on the shaft body of the rotating shaft 205, so as to adjust the braking gap of the adjusting arm body 5 by adjusting the adjusting nut 4.

[0034] Further, the inner side of the sealing rotating plate 201 is attached to the connecting handle 1, and the inner side of the sealing rotating plate 201 has damping. The damping on the inner side of the sealing rotating plate 201 improves the stability of the sealing rotating plate 201.

[0035] With the above structure, after the adjusting nut 4 is adjusted by the sealing rotating plate 201 in the sealing mechanism 2, after the adjusting nut 4 is adjusted, the sliding plate 202 between the sealing rotating plates 201 slides to one side of the adjusting nut 4, and the fixed damping groove 203 on one side of the sliding plate 202 is sleeved with the adjusting nut 4 to fix the adjusting nut 4, preventing the adjusting nut 4 from loosening due to vibration during the use of the product. Then, the rotating shaft 205 drives the gear disk 206 to rotate inward until it is engaged with the rack and the rack groove 204 in the gear disk 206, making the force required for the sealing rotating plate 201 to rotate greater, and cooperating with the adjusting nut 4 to complete the fixation of the sealing rotating plate 201. The sealing rings 3 on the front and rear sides of the adjusting arm body 5 wrap the parts where the adjusting arm body 5 contacts the outside. The internal rack 304 and the rotating disk 303 rotate with the adjusting arm body 5 to protect and seal the inside at all times. And the sealing ring 3 can be removed from the surface of the adjusting arm body 5 through the fixing groove 302, cleaned and reinstalled.

[0036] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the said claims.
