Description

Technical Field

[0001] The utility model relates to the field of vehicle safety protection, in particular to a mudguard bracket with adjustable angle. Background Technique

[0002] With the continuous development of technology, people have invented various means of transportation according to various mechanical structures in order to travel faster. These tools include ox carts, carriages, automobiles, bicycles, etc. Among them, bicycles are widely used by commuting workers because of their light weight, fast speed and small floor area. In order to prevent the mud on the road from wetting the clothes of cyclists due to the high-speed rotation of the wheels during driving, a mudguard is usually installed above the wheels of the bicycle.

[0003] The existing mudguards are usually divided into front mudguards and rear mudguards, and the front mudguards and rear mudguards are installed on the frame through corresponding mudguard brackets. The installation method is to fix the mudguard on the mudguard bracket through screws. Once the screw holes are offset, the mudguard cannot completely cover the wheel.

[0004] This kind of mudguard bracket installed on the frame is usually a fixed structure. It is difficult to adjust the angle position of the mudguard after installation, and only the height of the mudguard and the tire can be manually controlled. This makes it often occur that due to the size or precision problems of the frame (such as when the center point of the frame axle and the center point of the tire circle are not in the same plane), the mudguard cannot completely cover the wheel, resulting in the situation that the mudguard cannot completely block the mud, and the front and rear mudguards cannot be made universal. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that the mudguards of the existing mudguard brackets with adjustable angles cannot be made universal for front and rear mudguards, and the angle of the mudguard cannot be adjusted after installation.

[0006] To solve the above technical problems, the technical solution provided by the utility model is: a mudguard bracket with adjustable angle, including a mudguard and a mudguard bracket. An angle adjustment device is provided above the mudguard. The angle adjustment device includes a T-shaped turbine located outside the mudguard, a worm meshed with the T-shaped turbine, and a fixed shell for restricting the position of the worm. An arc-shaped groove for the inner wall of the T-shaped turbine is provided at the open end of the fixed shell. The limiting worm passes through the side wall of the fixed shell. The mudguard bracket is connected to the bottom surface of the fixed shell through a bolt structure. A rotatable fixing sleeve for fixing the frame is provided on one side of the mudguard bracket.

[0007] As an improvement, the rotation structure of the rotatable fixing sleeve includes a spur gear located on one side of the mudguard bracket and a gear sleeve corresponding to the spur gear provided inside the rotatable fixing sleeve.

[0008] As an improvement, the fender bracket is connected to the fixed sleeve through a bolt structure.

[0009] As an improvement, the spur gear is connected to the inner wall of the gear sleeve through the teeth of the spur gear.

[0010] As an improvement, the T-shaped turbine is connected to the outer wall of the fender by welding.

[0011] As an improvement, the arc surface side of the arc-shaped groove is in contact connection with the inner arc surface of the T-shaped turbine through the body.

[0012] The advantages of the present utility model compared with the prior art are as follows: The device is connected through the spur gear of the rotatable fixed sleeve, so that after the fender bracket and the fender are connected, they can be installed on the front wheel or the rear wheel according to requirements, making the front and rear fenders universal. When the center point of the frame shaft rod is not concentric with the center point of the wheel, the center point of the fender is changed to keep it in the same plane as the center point of the wheel; in the angle adjustment device, the meshing connection between the worm and the T-shaped turbine enables the fender to change the contact turbine teeth between the T-shaped turbine and the worm through the rotation of the worm, thereby changing the covering angle of the fender on the wheel and ensuring that the fender can be adjusted back after being installed incorrectly.

The spur gear 41 is connected to the inner wall of the gear sleeve 42 through the teeth of the spur gear 41. The clamping sleeve on the side of the rotatable fixing sleeve 4 is clamped on the shaft of the vehicle frame. Observe whether the center line of the rotatable fixing sleeve 4 and the center of the wheel are in the same plane. Adjust the angle of the clamping sleeve on the side of the rotatable fixing sleeve 4 so that the center line of the rotatable fixing sleeve 4 and the center are in the same plane. Use screws to tighten the clamping sleeve on the side of the rotatable fixing sleeve 4. Put the spur gear 41 on the top surface of the fender bracket 2 into the gear sleeve 42. At this time, the upper and lower angle adjustment ends of the fender bracket 2 are parallel to the wheel (the fender bracket 2 is usually L-shaped, and this angle is mostly greater than 90°). Use fixing screws to pass through the through hole in the center of the column of the rotatable fixing sleeve 4 and screw into the screw hole in the center of the spur gear 41 of the fender bracket 2 to fix the position (the spur gear 41 is welded above the fender bracket 2 by an electric welding machine).
