Description

Technical Field

[0001] The utility model relates to the technical field of automobile braking, in particular to a safety brake valve body. Background Art

[0002] The safety brake valve body is a key safety device specially designed for use in the braking system of an automobile to ensure the pressure safety of the braking system under extreme conditions. This valve body usually includes multiple safety protection mechanisms, such as an automatic pressure relief function, which can respond quickly when the system pressure exceeds the preset value and prevent damage or failure of the braking system by releasing pressure, thereby ensuring the safety of the vehicle and operator. The safety brake valve body has various structural forms and is suitable for different media and environmental conditions. It can operate under various nominal pressures and maximum applicable temperatures. It is an important component to improve the reliability of the braking system.

[0003] For example, a Chinese patent publication discloses a high-safety ABS brake valve body, application number: CN202221289888.1, comprising a valve body, wherein a first annular plate is fixedly sleeved on the right end of the valve body, an annular groove is defined on the right side of the first annular plate, an end cap is connected to the right side of the first annular plate, a groove is defined on the left side of the end cap, a plurality of screw rods are disposed around the inner wall of the annular groove, one end wall of each screw rod is rotatably connected to the bottom of the annular groove, a disc is rotatably connected to the bottom of the groove, a plurality of internally threaded tubes are fixedly connected around the left side of the disc, each of the internally threaded tubes is threadedly sleeved on the outer wall of a corresponding screw rod, a drive mechanism is provided at the bottom of the groove, and the drive mechanism is transmission-connected to the plurality of screw rods. This utility model simplifies the disassembly and assembly process of the end cap, facilitates repair of faulty devices, and ensures the safety of the brake valve body.

[0004] However, in the above technical solution, the fixed connection between the valve body and the end cap is achieved by using a threaded structure. The threaded portion of the threaded structure is extremely susceptible to environmental factors. Over time, the thread surface will gradually oxidize and form rust, which not only weakens the mechanical strength of the thread. Worse, the accumulation of rust may eventually lead to complete blockage of the threaded hole, making the connection between the valve body and the end cap unreliable. In addition, under the action of long-term tightening force, the threaded connection is prone to "cold welding" at the threads, that is, the long-term compression between the threads produces tiny metal-to-metal bonds, further increasing the difficulty of disassembly. Utility Model Content

[0005] The main purpose of the present invention is to provide a safe brake valve body, which can effectively solve the problem of fixed connection between the valve body and the end cover in the background technology, and a threaded structure is chosen to achieve this. The threaded part of the threaded structure is very susceptible to environmental factors. As time goes by, the thread surface will gradually oxidize and form rust, which not only weakens the mechanical strength of the thread, but even worse, the accumulation of rust may eventually cause the threaded hole to be completely blocked, making the connection between the valve body and the end cover no longer reliable. In addition, under the action of the tightening force for a long time, the threaded connection is prone to "cold welding" phenomenon at the thread, that is, the threads are compressed for a long time, resulting in tiny metal-to-metal bonds, which further increases the difficulty of disassembly.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A safety brake valve body includes a valve body, an end cover is provided on the valve body, a sealing ring is provided on the side of the valve body close to the end cover, a fixing component is provided on the side of the end cover close to the valve body, a connecting column is movably provided on the side of the end cover away from the valve body, a knob is provided on the connecting column, a cross sliding column is provided on the side of the connecting column away from the knob, a plurality of grooves are provided on the end cover, and a plug plate is movably provided in the grooves.

[0008] Preferably, the groove and the inserting plate are both L-shaped, and the inserting plate is fixedly connected to the connecting column.

[0009] Preferably, the fixing component includes a component base, a rotating column is provided on the component base, a rotating disk is provided on the rotating column, a plurality of positioning plates are provided on the rotating disk, a plurality of through grooves and a plurality of slots are provided on the component base, a positioning column is movably provided in the through groove, and a positioning slot is provided on the positioning column.

[0010] Preferably, a torsion spring and a cross slot are provided on the rotating column, and a spring is fixedly installed in the cross slot.

[0011] Preferably, the component base is fixedly mounted on the end cover, a portion of the positioning plug plate is located in the positioning groove, and the positioning column is fixedly connected to the valve body.

[0012] Preferably, the cross slide slides in the cross slide groove, and the spring is fixedly connected to the cross slide.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) When the present invention is used, when it is necessary to separate the valve body from the end cover, the connecting column is first moved away from the valve body by turning the knob, and the connecting column causes one end of the plug plate to leave the inside of the slot, and the spring is deformed. Then, the connecting column is rotated by turning the knob, and the connecting column causes the rotating column to rotate through the cross slide column and the cross slide groove, and the torsion spring is deformed. The rotating column drives the rotating disk to rotate, and the rotating disk drives the positioning plug plate to move, so that the positioning plug plate leaves the inside of the positioning slot, thereby releasing the fixation of the positioning column, so that the positioning column can leave the inside of the end cover, thereby releasing the fixed connection between the valve body and the end cover, so that the valve body and the end cover can be separated. The valve body and the end cover can be separated quickly, and there is no need to use a threaded structure as a whole, so there will be no problem of thread corrosion and difficulty in disassembly due to long-term tightening.

[0019] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1 and Figure 2As shown, a safety brake valve body includes a valve body 1, an end cover 2 is provided on the valve body 1, a sealing ring 3 is provided on the side of the valve body 1 close to the end cover 2, a fixing component 4 is provided on the side of the end cover 2 close to the valve body 1, a connecting column 5 is movably provided on the side of the end cover 2 away from the valve body 1, a knob 6 is provided on the connecting column 5, a cross sliding column 7 is provided on the side of the connecting column 5 away from the knob 6, a plurality of grooves 8 are provided on the end cover 2, and a plug plate 9 is movably provided in the groove 8.

[0021] like Figure 3 As shown, in another embodiment of the present invention, the fixing assembly 4 includes an assembly base 401, a rotating column 402 is provided on the assembly base 401, a rotating disk 403 is provided on the rotating column 402, a plurality of positioning plug plates 404 are provided on the rotating disk 403, a plurality of through slots 405 and a plurality of slots 406 are provided on the assembly base 401, a positioning column 407 is movably provided in the through slot 405, and a positioning slot 408 is provided on the positioning column 407;

[0022] The rotating column 402 is provided with a torsion spring 409 and a cross slot 4010 , and a spring 4011 is fixedly installed in the cross slot 4010 ;

[0023] When it is necessary to release the fixation of the positioning column 407, first, one end of the plug plate 9 is moved away from the interior of the slot 406 through the connecting column 5, the spring 4011 is deformed, and then the connecting column 5 is rotated. The connecting column 5 rotates the rotating column 402 through the cross slide column 7 and the cross slide groove 4010, and the torsion spring 409 is deformed. The rotating column 402 drives the rotating disk 403 to rotate, and the rotating disk 403 drives the positioning plug plate 404 to move, so that the positioning plug plate 404 leaves the interior of the positioning groove 408, thereby releasing the fixation of the positioning column 407, so that the positioning column 407 can leave the interior of the end cover 2. When the positioning column 407 needs to be fixed inside the end cover 2, the positioning column 407 is first inserted into the through slot 405, and then the rotating column 402 is rotated by the rebound of the torsion spring 409. The rotating column 402 causes the positioning plug plate 404 to enter the positioning slot 408 through the rotating disk 403, thereby fixing the positioning column 407. Subsequently, the spring 4011 rebounds to reinsert one end of the plug plate 9 into the slot 406, limiting the positioning plug plate 404 to prevent the positioning plug plate 404 from moving accidentally, thereby further fixing the position of the positioning column 407.

[0024] The working principle of this safety brake valve body:

[0025] When in use, when it is necessary to separate the valve body 1 from the end cover 2, first move the connecting post 5 in the direction away from the valve body 1 through the knob 6, and the connecting post 5 causes one end of the plug plate 9 to leave the inside of the slot 406, and the spring 4011 is deformed. Then, the connecting post 5 is rotated by the knob 6, and the connecting post 5 causes the rotating post 402 to rotate through the cross slide 7 and the cross slide groove 4010, and the torsion spring 409 is deformed. The rotating post 402 drives the rotating disk 403 to rotate, and the rotating disk 403 drives the positioning plug plate 404 to move, so that the positioning plug plate 404 leaves the inside of the positioning groove 408, thereby releasing the fixation of the positioning post 407, so that the positioning post 407 can leave the inside of the end cover 2, thereby releasing the fixed connection between the valve body 1 and the end cover 2, so that the valve body 1 and the end cover 2 can be separated. The valve body 1 and the end cover 2 can be separated quickly, and the overall structure does not require the use of a threaded structure, so there will be no thread corrosion and the problem of difficulty in disassembly due to long-term fastening.

[0026] 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 based on the above description. It is impossible to list all the implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
