Description

Technical Field

[0001] This utility model belongs to the field of anti-slip pump technology, and specifically relates to an anti-slip pump equipped with a high-pressure extension tube locking seal structure. Background Technology

[0002] The anti-skid pump is an important automotive safety component, primarily used to improve vehicle stability and handling during driving, especially on wet, icy, or other low-friction road surfaces. The anti-skid pump is typically integrated with the anti-lock braking system (ABS) and electronic stability control (ESC) to form a comprehensive vehicle control system. The extension tube, a crucial component connecting the anti-skid pump to other components of the braking system, is usually made of high-pressure resistant materials to ensure the reliability and safety of the hydraulic system. However, the inconvenient connection structure during extension tube use can affect pump performance. Prolonged connection can lead to the accumulation of dirt and impurities inside the tube, affecting fluid flow and reducing the anti-skid pump's efficiency, thus impacting the entire vehicle's braking system. Therefore, we aim to design an anti-skid pump equipped with a high-pressure extension tube locking seal structure to solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-slip pump equipped with a high-pressure extension pipe locking seal structure, so as to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: an anti-slip pump equipped with a high-pressure extension tube locking and sealing structure, comprising: an anti-slip pump, an installation plate fixedly connected to the right end of the anti-slip pump, an extension tube movably sleeved on the outside of the right output end of the anti-slip pump, a disassembly mechanism provided on the extension tube, and a sealing mechanism also provided on the right output end of the anti-slip pump;

[0005] The disassembly mechanism includes a ball bearing, a through groove is provided at the left end of the extension tube, and a groove is provided at the output end of the anti-slip pump. A ball bearing is movably fitted inside the through groove, and the groove contacts the ball bearing. By setting up the disassembly mechanism, it is convenient to disassemble and maintain the extension tube.

[0006] As a preferred embodiment, one section of the extension tube is a metal braided hose designed to improve the installation flexibility of the extension tube and withstand high pressure.

[0007] In a preferred embodiment, the disassembly mechanism further includes a fixing ring, which is fixedly sleeved on the outer side of the left end of the extension tube. A limiting ring is slidably sleeved on the outer side of the left end of the extension tube. The limiting ring and the fixing ring are elastically connected by a spring. By setting the spring, the elasticity of the spring is used to keep the limiting ring in contact with the ball bearing.

[0008] In a preferred embodiment, the inner side of the limiting ring is provided with an annular groove for providing space for ball displacement.

[0009] In a preferred embodiment, the front cross-section of the through groove is an arc-shaped structure that is narrow near the center of the extension tube and wide away from the center of the extension tube. By setting the arc-shaped through groove that is narrow near the center of the extension tube and wide away from the center of the extension tube, the balls are prevented from falling into the interior of the extension tube through the through groove.

[0010] In a preferred embodiment, the sealing mechanism includes an abutment ring, which is fixedly sleeved inside the left end of the extension tube, and the output end of the anti-slip pump is provided with an arc-shaped groove.

[0011] An O-ring is fitted inside the arc-shaped groove. The output end of the anti-slip pump is slidably sleeved inside the extension tube. A sealing ring is movably fitted between the output end of the anti-slip pump and the abutment ring. By setting a sealing mechanism, liquid leakage can be prevented.

[0012] In a preferred embodiment, the sealing mechanism further includes a wedge block, which is fixedly sleeved on the outside of the right end of the extension tube;

[0013] A second sealing ring is fixedly connected to the right side surface of the extension tube and the wedge, and a threaded sleeve is movably sleeved on the outer side of the right end of the extension tube.

[0014] In a preferred embodiment, the rear cross-section of the threaded sleeve is a trapezoidal structure that is narrower on the left and wider on the right, used to compress the extension tube and displace it.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. By setting up a disassembly mechanism, the extension tube is moved to squeeze the ball bearing, causing the ball bearing to shift and separate from the output end of the anti-slip pump, thus allowing the extension tube to be disassembled. This facilitates the disassembly and maintenance of the extension tube and avoids the accumulation of dirt and impurities inside the extension tube due to long-term connection, which would affect the smooth flow of fluid.

[0017] 2. By setting up a sealing mechanism, O-rings, sealing ring one, and sealing ring two are used to seal the left and right ends of the extension tube respectively, preventing liquid leakage and thus affecting the braking system. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 4 This utility model provides a technical solution: an anti-slip pump equipped with a high-pressure extension tube locking and sealing structure, including: an anti-slip pump 1, an mounting plate 2 fixedly connected to the right end of the anti-slip pump 1, an extension tube 3 movably sleeved on the outside of the right output end of the anti-slip pump 1, a disassembly mechanism 4 provided on the extension tube 3, and a sealing mechanism 5 provided on the right output end of the anti-slip pump 1.

[0028] The disassembly mechanism 4 includes a ball bearing 43. A through groove 41 is provided at the left end of the extension tube 3, and a groove 42 is provided at the output end of the anti-slip pump 1. The ball bearing 43 is movably fitted inside the through groove 41, and the groove 42 contacts the ball bearing 43. By setting the disassembly mechanism 4, it is convenient to disassemble and maintain the extension tube 3.

[0029] One section of the extension tube 3 is a metal braided hose designed to improve the installation flexibility of the extension tube 3 and to withstand high pressure.

[0030] The disassembly mechanism 4 also includes a fixing ring 44, which is fixedly sleeved on the outer side of the left end of the extension tube 3. A limiting ring 45 is slidably sleeved on the outer side of the left end of the extension tube 3. The limiting ring 45 and the fixing ring 44 are elastically connected by a spring 46. By setting the spring 46, the elasticity of the spring 46 is used to keep the limiting ring 45 in contact with the ball 43.

[0031] The inner side of the limiting ring 45 is provided with an annular groove 47 for providing displacement space for the ball 43.

[0032] The front cross-section of the through groove 41 is an arc-shaped structure that is narrow near the center of the extension tube 3 and wide away from the center of the extension tube 3. By setting the arc-shaped through groove 41 that is narrow near the center of the extension tube 3 and wide away from the center of the extension tube 3, the ball 43 is prevented from falling into the interior of the extension tube 3 through the through groove 41.

[0033] The sealing mechanism 5 includes an abutment ring 51, which is fixedly sleeved inside the left end of the extension tube 3. The output end of the anti-slip pump 1 is provided with an arc-shaped groove 53.

[0034] An O-ring 54 is fitted inside the arc groove 53. The output end of the anti-slip pump 1 is slidably sleeved inside the extension tube 3. A sealing ring 52 is movably fitted between the output end of the anti-slip pump 1 and the abutment ring 51. By setting the sealing mechanism 5, liquid leakage can be prevented.

[0035] The sealing mechanism 5 also includes a wedge 55, which is fixedly sleeved on the outside of the right end of the extension tube 3;

[0036] A sealing ring 56 is fixedly connected to the right side surface of the extension tube 3 and the wedge block 55, and a threaded sleeve 57 is movably sleeved on the outer side of the right end of the extension tube 3.

[0037] The rear cross-section of the threaded sleeve 57 is a trapezoidal structure that is narrow on the left and wide on the right, used to compress the extension tube 3 and displace the extension tube 3.

[0038] Please see Figure 1 ,to Figure 4As the first embodiment of this utility model: In use, when it is necessary to disassemble the extension tube 3, first move the limiting ring 45. During the displacement process, the limiting ring 45 compresses the spring 46 to deform it. When the limiting ring 45 moves to the point where its inner annular groove 47 is aligned with the ball 43, move the extension tube 3 to separate it from the output end of the anti-slip pump 1. During the displacement process, the extension tube 3 squeezes the ball 43. When the ball 43 moves into the annular groove 47 of the limiting ring 45, it disengages from the extension tube 3, so that the extension tube 3 can be easily disassembled to complete its maintenance and avoid the accumulation of dirt and impurities inside due to long-term connection, which would affect the smooth flow of liquid.

[0039] Please see Figure 1 , Figure 2 , Figure 3 As a second embodiment of this utility model: Based on the description in the above embodiments, further, during the installation of the extension tube 3, the extension tube 3 is first sleeved on the outside of the output end of the anti-slip pump 1. The output end of the anti-slip pump 1 is sealed at the connection between the output end of the anti-slip pump 1 and the extension tube 3 by squeezing the sealing ring 52. At the same time, the O-ring 54 on the outside of the output end of the anti-slip pump 1 performs a secondary seal to improve the sealing effect. In addition, by rotating the threaded sleeve 57, the threaded sleeve 57 and the external connecting pipe undergo threaded movement, causing the threaded sleeve 57 to move. During the displacement, the threaded sleeve 57 squeezes the wedge block 55 and the extension tube 3, causing the extension tube 3 to move. During the displacement, the extension tube 3 squeezes the sealing ring 56 to complete the sealing of the right end of the extension tube 3 and the external connecting pipe.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
