[0029] Application Overview

[0030] There is a brake oil pipe currently. Since the pipe body and the mounting seat are both made of metal, after welding, the relative position of the pipe body and the mounting seat is constant. It is only suitable for specific installation scenarios, and there is room for further improvement in versatility and ease of installation.

[0031] Based on the above technical problems, the present application proposes a brake oil pipe, wherein the brake oil pipe has a simple structure, does not involve complicated manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the brake oil pipe provided by the present application is easy to produce and low-cost, which is more conducive to controlling production costs and further conducive to product promotion and use.

[0032] Schematic brake hose,

[0033] refer to Figures 2 to 4 According to a preferred embodiment of the utility model, a brake oil pipe includes a pipe body assembly 10, wherein the pipe body assembly 10 is a metal pipe, and the pipe body assembly 10 has a first through hole 1011 extending therethrough.

[0034] Specifically, Figure 2 As shown, the tube body assembly 10 includes a first tube body 101, a second tube body 102 and a sensor seat body 103, the sensor seat body 103 is located between the first tube body 101 and the second tube body 102, and the two ends of the sensor seat body 103 are fixedly connected to the first tube body 101 and the second tube body 102 by welding, respectively, and the first through hole 1011 extends from the end of the second tube body 102 toward the first tube body 101 and penetrates to an end of the first tube body 101 away from the sensor seat body 103.

[0035] To achieve the connection between the end of the first tube 101 away from the sensor base 103 and the external brake cylinder, Figure 3 As shown, the brake oil pipe also includes a mounting base 20 for connecting to an external brake oil cylinder, the mounting base 20 is connected to an end of the first tube body 101 away from the sensor base body 103, the mounting base 20 has a second through hole 201, when the mounting base 20 is connected to the first tube body 101, the first through hole 1011 is connected to the second through hole 201.

[0036] It should be noted that, in the prior art, the mounting seat 20 and the first tube body 101 are fixedly connected by welding. Since the materials of the first tube body 101 and the mounting seat 20 are both metal, after the first tube body 101 and the mounting seat 20 are welded, the position of the first tube body 101 relative to the mounting seat 20 is fixed. Also, since the overall length of the first tube body 101 is relatively long, in the process of connecting the mounting seat 20 with the external brake oil pipe, the first tube body 101 that swings with the mounting seat 20 is at risk of colliding with other parts in the vehicle body, making installation inconvenient. Secondly, since the position of the first tube body 101 relative to the mounting seat 20 is fixed, the brake oil pipe is only suitable for specific installation scenarios and has poor versatility.

[0037] In view of this, in the embodiment of the present application, the mounting seat 20 is rotatably mounted on one end of the tube body assembly 10 .

[0038] Specifically, Figure 3 As shown, the mounting seat 20 also has a mounting hole 202, and a bearing is provided at the opening of the mounting hole 202 in an interference fit manner. One end of the first tube body 101 is interference fit with the inner ring of the bearing and extends into the mounting hole 202, so that the first through hole 1011 is connected with the second through hole 201.

[0039] It should be noted that, by rotating the mounting base 20 and installing it on the first tube body 101, when installing the brake oil pipe, the tube body assembly 10 can be rotated to a predetermined angle and placed in an open area, and then the mounting base 20 can be connected to the external brake oil cylinder. After the mounting base 20 and the external brake oil cylinder are pre-fixed, the operator rotates the tube body assembly 10 and rotates it to a specified installation position. Compared with the prior art, it is necessary to pay attention to not causing the tube body assembly 10 to collide with other parts on the vehicle body during the process of connecting the mounting base 20 with the external brake oil cylinder. In the embodiment of the present application, as long as it is determined that there is no motion interference in the circumferential rotation direction of the tube body assembly 10 during installation, the operator only needs to pay attention to the connection of the mounting seat 20 when installing the mounting seat 20. The operator does not need to distract his attention and take into account the installation interference of the tube body assembly 10 during this process. Compared with the prior art, the circumferential position of the tube body and the mounting seat 20 can be adjusted, which is helpful for installation. In addition, since the mounting seat 20 can rotate circumferentially relative to the tube body assembly 10, it can adapt to external brake cylinders at more angles. Compared with the prior art, it has the advantage of better versatility.

[0040] Furthermore, since the mounting seat 20 is rotatably connected to the tube body assembly 10 , the sealing performance of the connection between the mounting seat 20 and the first tube body 101 is required to be high.

[0041] Specifically, in order to improve the sealing performance of the connection between the mounting seat 20 and the first tube body 101, as Figure 3 and Figure 4 As shown, the brake oil pipe also includes a plurality of sealing rings 2031, and the sealing rings 2031 are arranged at the abutment between the first tube body 101 and the mounting seat 20. More specifically, a circular hole 203 is provided at one end of the second through hole 201 close to the mounting hole 202, and the circular hole 203 is used to place the sealing ring 2031. It should be noted that the material of the sealing ring 2031 is an elastic material, preferably rubber, and the height of the sealing ring 2031 is slightly greater than the hole depth of the circular hole 203. When the end of the first tube body 101 abuts against the wall surface of one end of the mounting hole 202 close to the circular hole 203, at the same time, the first tube body 101 presses the sealing ring 2031 and makes it slightly deformed and fills the circular hole 203 to improve the sealing performance; at the same time, the sealing ring 2031 extending out of the opening of the circular hole 203 also provides a margin for the subsequent wear of the sealing ring 2031.

[0042] In addition, in order to further improve the sealing performance of the connection between the mounting seat 20 and the first tube body 101, Figure 3As shown, the brake oil pipe also includes an inflatable ring 30, which is arranged in the mounting hole 202 and sleeved on the first tube body 101. When the inflatable ring 30 is filled with gas, the inner wall of the inflatable ring 30 fits with the outer wall of the first tube body 101, and the outer wall of the inflatable ring 30 fits with the hole wall of the mounting hole 202.

[0043] It should be noted that when rotating the first tube body 101, the installer extracts a portion of the gas in the inflatable ring 30 through a syringe, and the inflatable ring 30 is partially deflated at this time, thereby avoiding the wear of the inflatable ring 30 and the hole wall of the mounting hole 202 when the inflatable ring 30 is filled with gas. After the angular position of the first tube body 101 relative to the mounting seat 20 is determined, the installer inflates the inflatable ring 30 through an inflating needle connected to an external gas source, and fills the inflatable ring 30 with gas, so that the inner wall of the inflatable ring 30 fits with the outer wall of the first tube body 101, and the outer wall of the inflatable ring 30 fits with the hole wall of the mounting hole 202, thereby achieving another layer of sealing.

[0044] Furthermore, in order to selectively fix the circumferential position of the first tube body 101, as Figure 4 As shown, the side surface of one end of the first tube body 101 close to the mounting seat 20 has a plurality of annularly arranged embedding grooves 1012, and the mounting seat 20 has a first adjustment hole 204, and the first adjustment hole 204 is connected to the mounting hole 202. The brake oil pipe also includes a sliding member 2041. When the sliding member 2041 slides, the sliding member 2041 extends into the embedding groove 1012 and presses against the first tube body 101, or the sliding member 2041 is separated from the first tube body 101.

[0045] It should be noted that, when the sliding member 2041 extends into the embedding groove 1012 and presses against the first tube body 101, the side surface of the sliding member 2041 fits against the groove side surface of the embedding groove 1012. Since the sliding member 2041 only moves axially, the first tube body 101 is restricted by the sliding member 2041 and does not rotate circumferentially. When the sliding member 2041 is separated from the first tube body 101, the installer can rotate the first tube body 101.

[0046] Furthermore, in order to realize the axial movement of the sliding member 2041, as Figure 3 and Figure 4As shown, the brake oil pipe also includes a first threaded member 2042 and an elastic member 2043 for resetting the sliding member 2041, the elastic member 2043 is a spring, the first threaded member 2042 is located at one end of the sliding member 2041 away from the mounting hole 202, and the first threaded member 2042 is threadedly connected to the first adjustment hole 204, and one end of the elastic member 2043 abuts against the sliding member 2041.

[0047] It should be noted that when the first threaded member 2042 is tightened, the elastic member 2043 is compressed, and the sliding member 2041 is moved toward the first tube body 101 by the thrust of the first threaded member 2042, and at a certain moment, the sliding member 2041 presses against the side of the embedding groove 1012; when the first threaded member 2042 is loosened, the elastic force of the elastic member 2043 when it is reset will push the sliding member 2041 away from the first tube body 101.

[0048] Furthermore, in order to prevent the elastic member 2043 from being separated from the first adjustment hole 204, as Figure 4 As shown, the brake oil pipe further includes a sleeve ring 2044 , which is inserted into the mounting hole 202 , and one end of the elastic member 2043 facing away from the sliding member 2041 abuts against the sleeve ring 2044 .

[0049] In addition, in order to facilitate the installation of the collar 2044, the elastic member 2043 and the sliding member 2041, the mounting seat 20 is designed to be split. Figure 2 and Figure 3 As shown, the mounting seat 20 is further implemented as a first seat body portion 20A and a second seat body portion 20B. After the ring 2044, the elastic member 2043, the sliding member 2041 and other components are placed, the first seat body portion 20A is connected to the second seat body portion 20B, and the connection method includes but is not limited to welding or threaded connection.

[0050] Furthermore, in order to prevent the first tube body 101 from moving axially, Figure 4 As shown, a side surface of the embedding groove 1012 close to the second through hole 201 is an inclined surface, and the sliding member 2041 moves toward the first tube body 101 by a predetermined distance and then abuts against the inclined surface.

[0051] Furthermore, in order to prevent the inflatable ring 30 from leaking, Figure 3 As shown, the mounting seat 20 also has a second adjustment hole 205 , which is connected to the inflation hole of the inflation ring 30 . A rubber plug 2051 is provided in the second adjustment hole 205 , and the rubber plug 2051 closes the second adjustment hole 205 .

[0052] It should be noted that, during the process of evacuating air and inflating air, both the syringe barrel and the inflation needle of the syringe pass through the rubber stopper 2051, but after the needle is withdrawn, the rubber stopper 2051 is easy to close.

[0053] Furthermore, in order to prevent the rubber plug 2051 from falling out of the second adjustment hole 205, as Figure 3 As shown, the brake oil pipe also has a second threaded member 2052 , and the second threaded member 2052 is threadedly connected to the mounting seat 20 and pressed against the rubber plug 2051 .

[0054] In summary, the brake oil pipe based on the embodiment of the present application is explained, which provides the brake oil pipe with advantages such as adjustable circumferential position of the pipe body and the mounting seat, better versatility, and convenience for installation.

[0055] It is worth mentioning that in the embodiment of the present application, the brake oil pipe has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the brake oil pipe provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further facilitating product promotion and use.

[0056] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved.
