AI Technical Summary
If the existing caliper oil pipe shaking when connected, the position of the internal sealing gasket changes, resulting in the exposed gap affecting the seal. At the same time, the sealing gasket matches the connecting end of the matching caliper with a pipe and cannot be used again.
A modified caliper oil pipe is designed. By providing a connecting head at both ends of the oil pipe body, the outer wall of the connecting head is provided with a raised edge, and the outer wall of the screw pipe is threadedly connected inside the sub-pump. When the connecting head is connected to the oil inlet hole, the connecting head and the inner wall of the oil inlet hole are squeezed through the rotation of the screw pipe, sealing is achieved, and elastic tension is generated through the buffer port inside the connecting head to prevent position changes.
The sealing connection between the oil pipe body and the sub-pump is achieved without the need for a sealing gasket, which improves the sealing effect, and prevents position changes through the elastic buffer port, extends the service life.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of caliper oil pipes, and specifically relates to a modified caliper oil pipe. Background Art
[0002] The caliper oil pipe is an important part of the automotive braking system and is also known as the brake oil pipe. Its main function is to transmit the braking medium during the braking process of the vehicle, ensuring that the braking force can be transmitted to the brake shoes or calipers of the vehicle, thereby generating the braking force to make the braking effective at any time.
[0003] Currently, the caliper oil pipe is usually connected between the fuel injector and the fuel pressure regulator, used to transfer fuel to the injector or release excess fuel from the fuel pressure regulator. A sealing gasket is added at the connection port of the caliper oil pipe to be squeezed and in close contact with the inner wall of the connection port. However, when the engine shakes during the connection of the existing caliper oil pipe, the position of the internal sealing gasket changes, resulting in gaps that affect the sealing. At the same time, the sealing gasket is matched with the connection end of the caliper oil pipe and cannot be reused. Content of the Utility Model
[0004] To achieve the above object, the utility model provides the following technical solutions: including an oil pipe body, a slave cylinder, and connection nozzles; the connection nozzles are arranged on both sides of the slave cylinder, connection heads are respectively arranged at both ends of the oil pipe body, screw pipes are respectively sleeved at both ends of the oil pipe body, oil inlet holes are respectively opened inside the two connection nozzles, the two connection heads are respectively inserted inside the connection nozzles opposite to the oil inlet holes, a raised edge is arranged on the outer wall of the connection head, the outer wall of the screw pipe is threadedly connected inside the slave cylinder, and the upper end of the screw pipe is tightly attached to the raised edge.
[0005] Preferably, a buffer port is opened in the middle of the connection head, and the buffer port is in a C-shaped configuration.
[0006] Preferably, an extension piece is arranged on the outer wall of the screw pipe, and the extension piece is located at the outer end of the screw pipe.
[0007] Preferably, a sealing groove matching the raised edge is opened at the upper end of the screw pipe, and the raised edge is located inside the sealing groove.
[0008] Preferably, two threaded holes are opened inside the connection nozzle, the two threaded holes are respectively communicated with the two oil inlet holes, and the outer walls of the two screw pipes are respectively threadedly connected inside the two threaded holes.
[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: when the screw tube is threadedly connected inside the connecting nozzle and rotated inward, the outer wall of the connecting head is pressed against the inner wall of the oil inlet hole, sealing the connection between the connecting head and the oil inlet hole. Without a sealing gasket, the connection between the oil pipe body and the sub-pump can be completed. At the same time, through the buffer port opened inside the connecting head, elastic tension is generated to prevent position changes, further improving the sealing effect of the connection between the oil pipe body and the sub-pump.

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0016] Embodiment
[0017] Please refer to Figures 1-4 , in the figure: This embodiment is a preferred implementation manner in the technical solution, a modified caliper oil pipe, including an oil pipe body 1, a sub-pump 2, and a connecting nozzle 3; the connecting nozzles 3 are arranged on both sides of the sub-pump 2, the two ends of the oil pipe body 1 are respectively provided with connecting heads 4, the two ends of the oil pipe body 1 are respectively sleeved with screw tubes 5, oil inlet holes are respectively opened inside the two connecting nozzles 3, the two connecting heads 4 are respectively inserted inside the connecting nozzles 3 opposite to the oil inlet holes, a raised edge 7 is arranged on the outer wall of the connecting head 4, the outer wall of the screw tube 5 is threadedly connected inside the sub-pump 2, and the upper end of the screw tube 5 is tightly attached to the raised edge 7.
[0018] As Figure 2 , 4As shown, a buffer port 8 is provided in the middle part inside the connector 4. The buffer port 8 is in a C-shaped form. The buffer port 8 provided in the middle part inside the connector 4 is in a C-shaped irregular shape, causing the middle part of the connector 4 to be recessed inward.
[0019] As Figure 1 , 2 shown, an extension piece 6 is provided on the outer wall of the screw tube 5. The extension piece 6 is located at the outer end of the screw tube 5. Through the extension piece 6 provided at the outer end of the screw tube 5, it is convenient to rotate the screw tube 5.
[0020] As Figure 2 , 3 shown, a sealing groove 9 matching the convex edge 7 is provided at the upper end of the screw tube 5. The convex edge 7 is located inside the sealing groove 9. Through the sealing groove 9 provided at the upper end of the screw tube 5, the convex edge 7 of the connector 4 is inserted and connected inside the upper end of the screw tube 5.
[0021] As Figure 2 , 4 shown, two threaded holes (not marked in the attached drawing) are provided inside the connecting nozzle 3. The two threaded holes are respectively communicated with two oil inlet holes (not marked in the attached drawing). The outer walls of the two screw tubes 5 are respectively threadedly connected in the two threaded holes. Through the threaded holes provided inside the connecting nozzle 3, the screw tube 5 is threadedly connected inside the connecting nozzle 3 to constrain and fix the oil pipe body 1.
[0022] In this embodiment, first, all parts are installed. The connector 4 part is opposite to the oil inlet hole part. With the upper end of the screw tube 5 located below the convex edge 7, when the screw tube 5 is threadedly connected inside the connecting nozzle 3 and rotated inward, the upper end of the screw tube 5 pushes and presses the connector 4, and the port of the connector 4 is located inside the orifice of the oil inlet hole circle, causing the outer wall of the connector 4 to be pressed against the inner wall of the oil inlet hole, sealing the connection between the connector 4 and the oil inlet hole. Without a sealing gasket, the connection between the oil pipe body 1 and the sub-pump 2 can be completed. At the same time, through the buffer port 8 provided inside the connector 4, when the connector 4 is pressed, the upper part above the buffer port 8 of the connector 4 moves closer to the lower part, generating an elastic tension to prevent position changes and further improving the sealing effect of the connection between the oil pipe body 1 and the sub-pump 2.
