[0003] When the existing oil seal groove is connected to the oil pipe, due to the inability to guarantee the connection tightness, oil leakage is likely to occur. Summary of the Utility Model

[0004] The utility model aims at the problems existing in the prior art and proposes the following technical solutions:

[0005] An oil seal groove structure of a brake caliper, comprising a caliper, a piston cavity opened in the caliper, an oil inlet installed on the caliper, and an oil pipe inserted into the oil inlet; a side mounting plate is installed on the outer wall of the oil pipe, and the side mounting plate is inserted into a mounting groove, the mounting groove is opened in the oil inlet, a limiting plate is connected to the bottom end of the side mounting plate, and the bottom end of the limiting plate is inserted into the inner wall of the mounting groove.

[0006] The mounting groove is arranged in an inverted "convex" shape. With the insertion of the side mounting plate and the cooperation of the insertion of the limiting plate, the mounting groove can be completely blocked longitudinally.

[0007] As a preference of the above technical solution, a limiting insertion block is inserted into the top end of the side mounting plate, and the limiting insertion block is installed on a sealing cover plate. The sealing cover plate is installed on an elastic inner plate through a sliding mechanism. An elastic member is connected to the bottom end of the elastic inner plate, the bottom end of the elastic member is connected to a limiting groove, the limiting groove is opened at the top end of the oil inlet, a second sliding rail is opened on the inner wall of the limiting groove, and a sliding block is slidably connected in the second sliding rail. The sliding block is installed on the outer wall of the elastic inner plate.

[0008] Under the elastic potential energy of the elastic member and the sliding action of the sliding block and the second sliding rail, after the sealing cover plate together with the limiting insertion block is moved to the maximum limit value, after the side mounting plate is inserted into the mounting groove, the sealing cover plate is released. With the elastic potential energy of the elastic member, the limiting insertion block is inserted into the side mounting plate. At this time, the position of the oil pipe can be further limited in the vertical direction.

[0009] As a preference of the above technical solution, the sliding mechanism includes a first sliding rail opened at the top end of the elastic inner plate, and a sliding plate is slidably connected in the first sliding rail. The sliding plate is connected to the bottom end of the sealing cover plate.

[0010] First, move the sealing cover plate to the right until it is limited by the limiting insertion block. Then, under the elastic potential energy of the elastic member and the sliding action of the sliding block and the second slide rail, move the sealing cover plate together with the limiting insertion block to the maximum limit value. After the side mounting plate is inserted into the mounting groove, release the sealing cover plate. With the elastic potential energy of the elastic member, the bottom end of the limiting insertion block abuts against the side mounting plate. At this time, by pushing the sealing cover plate, the limiting insertion block can be inserted into the corresponding slot hole on the side mounting plate.

[0011] As an optimization of the above technical solution, the side view cross-sections of the sliding plates and the first slide rails are all in the shape of a "trapezoid".

[0012] Under the sliding action of the sliding plate and the first slide rail, the sealing cover plate is not easily detached from the elastic inner plate.

[0013] The beneficial effects of the present utility model are as follows:

[0014] In this application, a side mounting plate is installed outside the oil pipe. Under the sealing action of the insertion between the side mounting plate and the mounting groove and the insertion action of the limiting plate, the mounting groove can be completely blocked. At the same time, with the cooperation of the elastic mechanism, with the pressing of the sealing cover plate and the insertion action of the limiting insertion block, the stability of the insertion between the oil pipe and the side mounting plate and the mounting groove in the longitudinal direction is achieved. Through the mutual cooperation of the above structures, the sealing performance of the oil pipe inserted into the oil inlet is guaranteed, and oil leakage is not likely to occur.

[0021] In view of the problem in the prior art that when the oil seal groove is connected to the oil pipe, due to the inability to guarantee the connection sealing performance, oil leakage is likely to occur. On the outer side of the oil pipe 4, a side mounting plate 5 is installed. Under the plugging action of the sealing between the side mounting plate 5 and the mounting groove 6 and the plugging action of the limiting plate 7, the mounting groove 6 can be fully blocked. At the same time, in cooperation with the elastic mechanism, under the pressing of the sealing cover plate 9 and the plugging action of the limiting plug 8, the stability of the plugging between the oil pipe 4 and the side mounting plate 5 and the mounting groove 6 in the longitudinal direction is achieved. Through the mutual cooperation of the above structures, the sealing performance of the connection between the oil pipe 4 and the oil inlet 3 is guaranteed, and oil leakage is not likely to occur.

Inserting the oil pipe 4 into the oil inlet 3 and sending dielectric oil into the piston cavity 2 are well-known to those skilled in the art, and the present application will not elaborate too much.

The mounting groove 6 is opened in the oil inlet 3. The bottom end of the side mounting plate 5 is connected with a limiting plate 7, and the bottom end of the limiting plate 7 is inserted into the inner wall of the mounting groove 6. The mounting groove 6 is set in an inverted "convex" shape. With the insertion of the side mounting plate 5 and the cooperation of the insertion of the limiting plate 7, the mounting groove 6 can be completely blocked longitudinally. The top end of the side mounting plate 5 is inserted with a limiting plug 8, and the limiting plug 8 is installed on the sealing cover plate 9. The sealing cover plate 9 is installed on the elastic inner plate 12 through a sliding mechanism. The bottom end of the elastic inner plate 12 is connected with an elastic member 15, and the bottom end of the elastic member 15 is connected in the limiting groove 16.

With the elastic potential energy of the elastic member 15, the limiting plug 8 is inserted into the side mounting plate 5, and at this time, the position of the oil pipe 4 can be further limited in the vertical direction. The sliding mechanism includes a first slide rail 11 opened at the top end of the elastic inner plate 12, and a slide plate 10 is slidably connected in the first slide rail 11.
