Description

Technical Field

[0001] The utility model relates to the technical field of brake equipment, in particular to a double-acting mechanical disc. Background Art

[0002] Double-action mechanical disc (also called dual-action disc brake or bidirectional mechanical disc brake) is a braking system commonly found on bicycles, motorcycles and some cars. This braking system activates the braking mechanism by operating the brake handle (or brake lever) to slow down or stop the vehicle. Double-action mechanical disc brake is an efficient, durable and easy-to-adjust braking system widely used in various vehicles.

[0003] As disclosed in a Chinese patent: A double-action mechanical disc brake structure, application number: CN202121435521.1, includes a first shell, a second shell, a rotating drive arm, a first brake pad and a second brake pad, a spring plate between the first brake pad and the second brake pad, a rotating drive arm having a closed end, a first open end and a second open end, the closed end is linked to the pull wire, the first open end and the second open end are respectively connected to the first shell and the second shell through a first braking structure and a second braking structure; the first braking structure and the second braking structure can convert rotation and translation, so that the first open end and the second open end are close to or away from each other. The first shell and the second shell can protect the internal components, and the elastic force of the rotating drive arm and the spring plate is superimposed to ensure the reliability and stability of the double-action mechanical disc brake structure.

[0004] However, in the above technical solution, the double-acting mechanical disc is widely used in various vehicles due to its advantages of high efficiency, durability and easy adjustment. When braking, the disc is locked by the brake pad, thereby braking. The structure of the above technical solution is not simple enough, and during the installation of the double-acting mechanical disc, the position of the double-acting mechanical disc needs to be adjusted accordingly according to the style of the disc. The traditional adjustment method is to adjust the position of the double-acting mechanical disc through a sliding column, and then fix it with bolts after the adjustment is completed. Each subsequent adjustment requires first releasing the bolt fixation, and then adjusting the position of the double-acting mechanical disc, and then fixing it with bolts after the adjustment is completed. It is cumbersome and inconvenient to adjust the position of the double-acting mechanical disc. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] The main purpose of the utility model is to provide a double-acting mechanical disc, which can effectively solve the problem that the double-acting mechanical disc in the background technology is widely used in various vehicles because of its advantages of high efficiency, durability and easy adjustment. When braking, the disc is locked by the brake pad, thereby braking. However, the structure of the above technical solution is not simple enough, and during the installation process of the double-acting mechanical disc, the position of the double-acting mechanical disc needs to be adjusted accordingly according to the style of the disc. The traditional adjustment method is to adjust the position of the double-acting mechanical disc by a sliding column, and then fix it with bolts after the adjustment is completed. Each subsequent adjustment requires first releasing the bolt fixation, and then adjusting the position of the double-acting mechanical disc, and then fixing it with bolts after the adjustment is completed. It is relatively cumbersome and inconvenient to adjust the position of the double-acting mechanical disc.

[0007] (II) Technical solution

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] A double-action mechanical disc comprises a main body and a frame, wherein the main body is provided with two rotating columns, two push plates are provided between the two rotating columns, two brake pads are provided between the two push plates, a plurality of arc grooves are provided on the outer wall on the side where the rotating columns and the push plates are close to each other, balls are provided in the arc grooves, a plurality of guide grooves are provided on the push plates, and two mounting holes are provided on the side of the main body close to the frame, and a connecting mechanism is provided in the mounting holes.

[0010] Preferably, the arc-shaped groove is an inclined groove, the inclination direction of the arc-shaped groove on the push plate is opposite to the inclination direction of the arc-shaped groove on the rotating column, and the frame is connected to the main body through a connecting mechanism.

[0011] Preferably, the connecting mechanism comprises a mechanism base, and the mechanism base is provided with a through groove and a threaded hole.

[0012] Preferably, a hollow threaded column is provided in the threaded hole, a knob is provided at one end of the hollow threaded column away from the through groove, and a fixed connecting tube is provided in the inner cavity of the hollow threaded column.

[0013] Preferably, the mechanism base is fixedly connected to the main body, and the through groove and the threaded hole are interconnected.

[0014] Preferably, the hollow threaded column is rotatably connected to a fixed connecting pipe.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] (1) The utility model first connects the frame and the main body through a connecting mechanism, and then rotates the knob to adjust the position of the main body. When braking is required, the two rotating columns are rotated, and the arc grooves on the rotating columns rotate with the rotating columns. Then the arc grooves on the push plate squeeze the ball bearings, and the ball bearings squeeze the push plate, so that the push plate moves towards the direction of the brake pads. The guide groove is responsible for ensuring the moving direction of the push plate and for preventing the push plate from rotating accidentally. The push plate drives the brake pads to move, so that the two brake pads move towards the disc and lock the disc, thereby completing the braking. Not only is the structure simple, but it is also convenient to adjust the position of the main body, and the structure is stronger. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with 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 of 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.

[0023] like Figures 1 to 3As shown, a double-action mechanical disc includes a main body 1 and a frame 2, two rotating columns 3 are arranged on the main body 1, two push plates 4 are arranged between the two rotating columns 3, two brake pads 5 are arranged between the two push plates 4, a plurality of arc grooves 6 are arranged on the outer wall on the side where the rotating columns 3 and the push plates 4 are close to each other, balls 7 are arranged in the arc grooves 6, a plurality of guide grooves 8 are arranged on the push plates 4, two mounting holes 9 are arranged on the side of the main body 1 close to the frame 2, and a connecting mechanism 10 is arranged in the mounting holes 9.

[0024] like Figure 4 As shown, in another embodiment of the present utility model, the connecting mechanism 10 includes a mechanism base 1001, and the mechanism base 1001 is provided with a through slot 1002 and a threaded hole 1003;

[0025] A hollow threaded column 1004 is arranged in the threaded hole 1003, and a knob 1005 is arranged at one end of the hollow threaded column 1004 away from the through groove 1002, and a fixed connecting tube 1006 is arranged in the inner cavity of the hollow threaded column 1004. First, the bolt is passed through the inner cavity of the fixed connecting tube 1006, and then the connecting mechanism 10 can be connected to the frame 2 by the bolt, so that the frame 2 and the main body 1 are connected through the connecting mechanism 10. Then, when the position of the main body 1 needs to be adjusted, the knob 1005 is first rotated, and the knob 1005 drives the hollow threaded column 1004 to rotate, and the hollow threaded column 1004 moves the mechanism base 1001 to one side through the threaded hole 1003, and the mechanism base 1001 drives the main body 1 to move, so as to adjust the position of the main body 1. Compared with the traditional method of adjusting the position of the main body 1 by using a sliding column, it is not only convenient to adjust the position of the main body 1, but also has stronger structurality.

[0026] The working principle of a double-action mechanical disc:

[0027] When in use, firstly, the connecting mechanism 10 is connected to the frame 2 by bolts, thereby connecting the frame 2 to the main body 1 through the connecting mechanism 10, and then the knob 1005 is turned, the knob 1005 drives the hollow threaded column 1004 to rotate, the hollow threaded column 1004 moves the mechanism base 1001 to one side through the threaded hole 1003, and the mechanism base 1001 drives the main body 1 to move, thereby adjusting the position of the main body 1. When braking is required, firstly the two rotating columns 3 are rotated, and the arc grooves 6 on the rotating columns 3 follow the rotating columns 3 rotates, and then the arc groove 6 on the push plate 4 squeezes the ball 7, so that the ball 7 gradually moves along the trajectory of the arc groove 6 to the side of the arc groove 6 close to the surface of the rotating column 3. At this time, the ball 7 squeezes the push plate 4, so that the push plate 4 moves towards the direction of the brake pad 5, and the guide groove 8 is responsible for ensuring the moving direction of the push plate 4 and preventing the push plate 4 from rotating accidentally. The push plate 4 drives the brake pad 5 to move, so that the two brake pads 5 are close to the disc and lock the disc, thereby completing the braking. Not only is the structure simple, but it is also convenient to adjust the position of the main body, and the structure is stronger.

[0028] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
