Description

Technical Field

[0001] This utility model relates to the field of motorcycle exhaust pipe bracket technology, and more specifically, to a motorcycle exhaust steel pipe mounting angle adjustment bracket. Background Technology

[0002] As a core component of the engine exhaust system, the installation angle of the motorcycle exhaust pipe directly affects exhaust efficiency, overall vehicle power performance, and riding safety. The exhaust pipe needs to be fixed to the frame of the motorcycle using a special bracket. The bracket not only needs to bear the weight of the exhaust pipe, but also needs to adapt to the differences in body structure, engine layout, and exhaust system design of different motorcycle models.

[0003] In the prior art, patent CN221162206U discloses an exhaust pipe mounting bracket, including two sets of connecting housings arranged opposite each other. The bottom ends of the two sets of connecting housings are connected by a connecting rotating block. Both sets of connecting housings have a buffer mechanism inside, and when the two sets of connecting housings are combined, they clamp and fix the exhaust pipe. Connecting brackets are symmetrically fixed to the outer walls of the two sets of connecting housings. The connecting rotating block allows the two sets of connecting housings to be quickly flipped and combined, enabling direct installation without disassembling the exhaust pipe. It provides a full-around, enveloping installation, and the internal buffer mechanism effectively cushions and supports the exhaust pipe during driving.

[0004] However, the existing technology still has the following technical problems in use: the connecting bracket is fixedly connected to the connecting housing and the connecting bracket is fixedly installed on the vehicle frame, so the installation angle of the exhaust pipe cannot be adjusted. When facing the layout differences of the body frame of different models or the need for exhaust system modification, it is difficult to match the vehicle body installation position, and the adaptability is poor. Utility Model Content

[0005] The main objective of this invention is to provide a motorcycle exhaust pipe mounting angle adjustment bracket, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A motorcycle exhaust pipe mounting angle adjustment bracket includes two pipe supports, which are fixedly sleeved onto the exhaust pipe body. One of the pipe supports is provided with an angle adjustment mechanism, which includes a rotating sleeve and a fixed sleeve. The rotating sleeve is movably inserted into the fixed sleeve. A plurality of first limiting teeth and second limiting teeth are respectively circumferentially arranged on the outer circumferential surface of the rotating sleeve and the inner circumferential surface of the fixed sleeve. The first limiting teeth and the second limiting teeth mesh with each other. The fixed sleeve is provided with a limiting mechanism, and a mounting plate is fixedly connected to one side of the fixed sleeve.

[0008] Preferably, a connecting piece is fixedly connected to one end of the rotating sleeve, and the connecting piece is fixedly connected to the outer side of the pipe rack.

[0009] Preferably, a mounting base is rotatably connected inside the rotating sleeve, and a first spring is fixedly connected to the mounting base.

[0010] Preferably, the first spring is sleeved inside the fixed sleeve, and the end of the first spring away from the mounting base is fixedly connected to the mounting plate.

[0011] Preferably, the limiting mechanism includes several limiting blocks, which are slidably inserted into the fixed sleeve, and the inner wall of the fixed sleeve is provided with several grooves for accommodating the limiting blocks.

[0012] Preferably, a second spring is provided inside the limiting block, and the two ends of the second spring are fixedly connected to the inner wall of the limiting block and the outer peripheral surface of the fixing sleeve, respectively.

[0013] Preferably, an inner threaded sleeve is fixedly fitted onto the fixed sleeve, and an outer threaded sleeve is threaded onto the inner threaded sleeve.

[0014] Preferably, the end of the limiting block away from the fixed sleeve is set as an inclined surface, and the two ends of the outer threaded sleeve abut against the inner threaded sleeve and the limiting block, respectively.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) By setting an angle adjustment mechanism, through the rotation and sliding cooperation of the rotating sleeve and the fixed sleeve, as well as the meshing of the first limiting tooth and the second limiting tooth, the installation angle can be adapted to different vehicle body structures and installation angle requirements without replacing the main structure of the bracket, thus solving the problem that the existing bracket structure cannot adjust the exhaust pipe angle and has poor adaptability.

[0017] (2) In order to improve the stability of the rotating sleeve during the motorcycle's operation, a limiting mechanism is set up. By rotating the outer threaded sleeve, it moves along the inner threaded sleeve towards the limiting block. During the movement, one end of the outer threaded sleeve abuts against the limiting block and slides along the inclined surface of the limiting block, so that the limiting block compresses the second spring. The lower end extends to one side of the rotating sleeve, which can limit the rotating sleeve and prevent the exhaust pipe body from rotating due to the vibration of the vehicle body.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] like Figure 1 , Figure 5 , Figure 6 As shown in the figure, this utility model embodiment proposes a motorcycle exhaust steel pipe mounting angle adjustment bracket, including two pipe brackets 1, which are fixedly sleeved on the exhaust pipe body 5. One of the pipe brackets 1 is provided with an angle adjustment mechanism 2, which includes a rotating sleeve 22 and a fixed sleeve 23. The rotating sleeve 22 is movably inserted into the fixed sleeve 23. A plurality of first limiting teeth 221 and second limiting teeth 231 are respectively circumferentially arranged on the outer circumferential surface of the rotating sleeve 22 and the inner circumferential surface of the fixed sleeve 23. The first limiting teeth 221 and the second limiting teeth 231 mesh with each other. The fixed sleeve 23 is provided with a limiting mechanism 3, and a mounting piece 4 is fixedly connected to one side of the fixed sleeve 23.

[0027] like Figures 1-6 As shown, a connecting piece 21 is fixedly connected to one end of the rotating sleeve 22. The connecting piece 21 is fixedly connected to the outer side of the pipe rack 1. A mounting base 24 is rotatably connected inside the rotating sleeve 22. A first spring 25 is fixedly connected to the mounting base 24. The first spring 25 is sleeved inside the fixed sleeve 23. The end of the first spring 25 away from the mounting base 24 is fixedly connected to the mounting piece 4.

[0028] The rotating sleeve 22 is fixedly connected to the pipe bracket 1 via the connecting piece 21, so that the pipe bracket 1 and the rotating sleeve 22 move synchronously. When it is necessary to adjust the installation angle of the exhaust pipe body 5, first release the limiting mechanism 3 from limiting the rotating sleeve 22, and then push the exhaust pipe body 5 forward to retract the first spring 25. The first limiting tooth 221 and the second limiting tooth 231 slide relative to each other until they disengage. The exhaust pipe body 5 can be rotated according to the required installation angle. The exhaust pipe body 5 drives the pipe bracket 1 and the rotating sleeve 22 to rotate synchronously. The first limiting tooth 221 rotates synchronously with the rotating sleeve 22. After adjusting the position, slowly release the exhaust pipe body 5 so that the rotating sleeve 22 resets under the elastic force of the first spring 25. The first limiting tooth 221 re-engages with the second limiting tooth 231, thereby realizing the angle adjustment and fixation of the motorcycle exhaust steel pipe installation.

[0029] By setting up this angle adjustment mechanism 2, the installation angle can be adapted to different vehicle body structures and installation angle requirements without replacing the main structure of the bracket, thus solving the problem that the existing bracket structure cannot adjust the exhaust pipe angle and has poor adaptability.

[0030] like Figures 1-3 , Figure 5 , Figure 6 As shown, the limiting mechanism 3 includes several limiting blocks 33. The limiting blocks 33 are slidably inserted into the fixed sleeve 23. Several grooves 26 for accommodating the limiting blocks 33 are provided on the inner wall of the fixed sleeve 23. A second spring 34 is provided inside the limiting block 33. The two ends of the second spring 34 are fixedly connected to the inner wall of the limiting block 33 and the outer peripheral surface of the fixed sleeve 23, respectively. An inner threaded sleeve 31 is fixedly sleeved on the fixed sleeve 23. An outer threaded sleeve 32 is threaded onto the inner threaded sleeve 31. The end of the limiting block 33 away from the fixed sleeve 23 is set as an inclined surface. The two ends of the outer threaded sleeve 32 abut against the inner threaded sleeve 31 and the limiting block 33, respectively.

[0031] Several limiting blocks 33 are circumferentially inserted into the fixed sleeve 23. In the initial state, one end of the limiting block 33 located inside the fixed sleeve 23 abuts against the groove 26 under the elastic force of the second spring 34. The sleeve 22 can slide back and forth normally along the inner wall of the fixed sleeve 23 when rotated. After the angle is adjusted, under the elastic force of the first spring 25, the first limiting tooth 221 abuts against the inner wall of the fixed sleeve 23 away from the mounting piece 4. The first limiting tooth 221 and the second limiting tooth 231 mesh with each other and limit each other. 5. To improve the stability of the rotating sleeve 22 during motorcycle operation, a limiting mechanism 3 is set up. By rotating the outer threaded sleeve 32, it moves along the inner threaded sleeve 31 towards the limiting block 33. During the movement, one end of the outer threaded sleeve 32 abuts against the limiting block 33 and slides along the inclined surface of the limiting block 33, so that the limiting block 33 compresses the second spring 34. The lower end extends to one side of the rotating sleeve 22, which can limit the rotating sleeve 22, thereby preventing the exhaust pipe body 5 from rotating due to vehicle vibration.

[0032] The working principle of this motorcycle exhaust pipe mounting angle adjustment bracket:

[0033] First, the entire bracket is fixed to the motorcycle frame using the mounting plate 4. The pipe bracket 1 is then initially fixed to the exhaust pipe body 5. Adjustments are made according to the required installation angle of the exhaust pipe body 5. During adjustment, the outer threaded sleeve 32 is rotated away from the mounting plate 4, releasing the pressure on the limiting block 33. Under the elastic force of the second spring 34, the limiting block 33 pops outward, and one end located inside the fixing sleeve 23 retracts into the groove 26. Then, the exhaust pipe body 5 is pushed towards the mounting plate 4, causing the rotating sleeve 22 to slide along the inner wall of the fixing sleeve 23 and compressing the first spring 25. The first limiting tooth 221 gradually disengages. After disengaging from the second limiting tooth 231, the exhaust pipe body 5 can be rotated to adjust its installation angle. After adjustment, the exhaust pipe body 5 is slowly released, and the rotating sleeve 22 gradually returns to its original position under the elastic force of the first spring 25. The first limiting tooth 221 and the second limiting tooth 231 re-engage, restricting the rotation of the exhaust pipe body 5. Then, by rotating the outer threaded sleeve 32 in the opposite direction, it is brought closer to the limiting block 33, and the limiting block 33 is gradually pressed inward, so that a part of the limiting block 33 inside the fixed sleeve 23 blocks the rotating sleeve 22, limiting the rotation of the sleeve 22 and ensuring the stability of the exhaust pipe body 5 during vehicle operation.

[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
