Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figure 1-2 , the present utility model provides a technical solution:

[0020] In this technical solution, a motorcycle brake pump includes a brake pump main body 1 and a connecting ring body 2. The connecting ring body 2 is installed on the side wall of the brake pump main body 1. The connecting ring body 2 can be sleeved on the outer side of an external motorcycle handlebar. An oil cup 3 is installed above the brake pump main body 1, and a cover 4 is buckled above the oil cup 3;

[0021] A retaining ring 5 is installed below the cover 4. A sealing ring 6 is sleeved on the outer side of the retaining ring 5. The sealing ring 6 can be attached to the inner wall of the oil cup 3. The sealing ring 6 includes a sealing sleeve ring 61, an annular air pipe 62, an air inlet pipeline 63 and a valve body 64. Both the sealing sleeve ring 61 and the annular air pipe 62 are sleeved on the outer side of the retaining ring 5. One end of the air inlet pipeline 63 is inserted and installed on the upper wall of the cover 4, and the other end of the air inlet pipeline 63 is communicated with the annular air pipe 62. A valve body 64 is installed at one end of the air inlet pipeline 63 located outside the cover 4;

[0022] In this technical solution, by arranging the annular air pipe 62 inside the sealing sleeve ring 61, air can be inflated into the annular air pipe 62 to make the annular air pipe 62 expand, so that the sealing sleeve ring 61 is pushed outward, thereby making the sealing sleeve ring 61 closely attached to the inner wall of the oil cup 3, thus improving the sealing performance between the oil cup 3 and the cover 4, preventing the entry of external dust, and preventing the situation of non-return of the brake.

[0023] In some technical solutions, a relief groove 7 is formed on the inner side wall of the sealing sleeve ring 61. The annular air pipe 62 can be inserted and installed in the relief groove 7. A clamping groove 8 is formed on the outer side wall of the retaining ring 5. Both the sealing sleeve ring 61 and the annular air pipe 62 are arranged in the clamping groove 8.

[0024] In this technical solution, through the arrangement of the clamping groove 8, the sealing sleeve ring 61 and the annular air pipe 62 can be positioned to prevent displacement of the two, affecting the sealing performance between the oil cup 3 and the cover 4.

[0025] In some technical solutions, a through hole 9 is formed on the upper wall of the cover 4. A fastening bolt 10 is inserted and installed in the through hole 9. A threaded hole 11 is formed on the upper wall of the oil cup 3. The fastening bolt 10 can be screwed and installed in the threaded hole 11.

[0026] In this technical solution, the cover 4 is installed on the oil cup 3 through the cooperation between the fastening bolt 10 and the threaded hole 11, so as to seal the oil cup 3. On the one hand, it ensures that external dust does not enter the oil cup 3, and on the other hand, it can prevent the oil in the oil cup 3 from leaking.

[0027] In some technical solutions, the connecting ring body 2 includes a first ring body 21, a second ring body 22, a locking screw 23, a mounting hole 24 and an anti-slip pad 25. The first ring body 21 is installed on the side wall of the brake pump body 1. The side wall of the first ring body 21 is provided with a mounting hole 24 with internal threads. The side wall of the second ring body 22 is inserted and installed with a locking screw 23, and the locking screw 23 can be screwed into the mounting hole 24. Anti-slip pads 25 are fitted and installed on the inner side walls of the first ring body 21 and the second ring body 22.

[0028] In this technical solution, the connecting ring body 2 in this article belongs to a split structure. When installing this device on an external motorcycle handlebar, first remove the second ring body 22 from the first ring body 21, and set the two on the front and back sides of the motorcycle handlebar respectively. Then, through the cooperation between the locking screw 23 and the mounting hole 24 of the first ring body 21 and the second ring body 22, this device is fixed on the external motorcycle handlebar.

[0029] In some technical solutions, a rearview mirror mounting bracket 12 is installed above the brake pump body 1, and an external rearview mirror can be screwed into the rearview mirror mounting bracket 12.

[0030] In some technical solutions, the valve body 64 is a valve core, and a retaining cap 13 is sleeved outside the valve body 64.

[0031] In this technical solution, the setting of the retaining cap 13 can protect the valve body 64 and also ensure the cleanliness of the valve body 64.

[0032] Working principle: When installing this device on an external motorcycle handlebar, first remove the second ring body 22 from the first ring body 21, and set the two on the front and back sides of the motorcycle handlebar respectively. Then, through the cooperation between the locking screw 23 and the mounting hole 24 of the first ring body 21 and the second ring body 22, this device is fixed on the external motorcycle handlebar. Then, by opening the cover 4, oil is injected into the oil cup 3, and then the oil cup 3 is sealed by the cover 4, and the cover 4 is fixed by the fastening bolt 10. Then, the valve body 64 at the end of the intake pipeline 63 is connected to an external air pipeline, and air is inflated into the annular air pipeline 62 through the air pipeline and the intake pipeline 64, so that the annular air pipeline 62 expands, and the sealing sleeve ring 61 is pushed outward, so that the sealing sleeve ring 61 is closely attached to the inner wall of the oil cup 3, thereby improving the sealing performance between the oil cup 3 and the cover 4, preventing external dust from entering, and preventing the situation of non-return of the brake.
