Description

Technical Field

[0001] The utility model belongs to the technical field of pump pressure test, and more specifically, relates to a connection structure for cylinder liner pump pressure test. Background Art

[0002] A cylinder liner, also known as a cylinder sleeve, is an important component in an internal combustion engine. It is installed in the cylinder block of the engine, and its main function is to provide an accurate guiding surface for the piston to ensure the accuracy and sealing performance of the piston movement, thereby improving the working efficiency of the engine. During the engine assembly process, after the cylinder liner unit is pre-assembled, in order to detect the correctness of the machining and assembly of each part of the cylinder liner unit, it is necessary to conduct a water pressure sealing performance test on this unit.

[0003] Currently, when conducting a water pressure sealing test on the cylinder liner unit, after pumping water with a certain water pressure into the cylinder liner unit, when the water pressure in the cylinder liner unit reaches the test pressure, the pipeline is closed and observed for a certain period of time. If the water pressure inside this unit remains constant, it indicates no leakage point and the test is qualified; otherwise, it is unqualified.

[0004] Currently, the water inlet pipe of the cylinder liner unit and the water outlet of the water supply pipe of the pump pressure test device are generally connected through a quick connector. When connecting, generally, it is necessary to manually push the push sleeve on the female connector backward, then insert the male connector into the female connector, and then release the push sleeve. The push sleeve will return to its original position, and at this time, the connection between the male connector and the female connector is achieved. However, generally, this series of processes is manually operated. Especially when a large number of cylinder liner units need to be connected, it consumes a lot of labor intensity and time, the connection efficiency is low, and it is also prone to operation errors, which will affect the progress of the water pressure sealing test of the cylinder liner unit.

[0005] Therefore, it is necessary to provide a connection structure for cylinder liner pump pressure test to solve the above technical problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a connection structure for cylinder liner pump pressure test to solve the above technical problems.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A connection structure for cylinder liner pump pressure test is used for connecting the water supply pipe and the water inlet pipe on the cylinder liner unit. The end of each branch of the water supply pipe and the end of the water inlet pipe are respectively provided with a female connector and a male connector. A push sleeve is slidably arranged on the female connector, and further includes:

[0009] An installation mechanism is arranged on the water supply pipe and is used to drive a plurality of the male connectors to be connected with the female connectors synchronously;

[0015] A blocking block, elastically arranged in the through hole, and the lower end of the blocking block is a slope.

[0016] As a further solution of the present utility model: An inner groove is formed in the baffle plate, the blocking block is slidably connected to the inner groove, and a first elastic member is arranged between the inner wall of the inner groove and the blocking block.

[0017] As a further solution of the present utility model: The pushing member includes:

[0018] An adapter rod, arranged at the bottom of the second sliding sleeve, and a plurality of pushing rods are arranged on the adapter rod;

[0019] A support plate, arranged on the support plate, and a second elastic member is arranged between the support plate and the second sliding sleeve.

[0020] As a further solution of the present utility model: A push block is arranged on the long plate, a transmission cavity is formed in the second sliding sleeve, a moving rod and a trigger rod are slidably arranged in the transmission cavity, and a first wedge block and a second wedge block which are slidably matched are respectively arranged on the moving rod and the trigger rod.

[0021] As a further solution of the present utility model: A moving groove is formed in the transmission cavity, a slider connected to the moving rod is slidably arranged in the moving groove, and a third elastic member is arranged between the slider and the inner wall of the moving groove.

[0022] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0023] 1. With this solution, the male connector and the female connector can be connected and installed together through the mobile installation mechanism, avoiding the current method where manual operation is required to move the push sleeve with one hand and insert the male connector into the female connector with the other hand. The same principle applies to disassembly, which can greatly reduce the labor intensity of the staff, save a lot of time, have high connection efficiency, and significantly reduce the occurrence of operation errors and the impact on the progress of the hydraulic pressure seal test of the cylinder liner unit.

[0024] 2.

[0025] 2. In this solution, when the first sliding sleeve is moved to drive the male connector to insert into the female connector, the long plate on the first sliding sleeve will push the moving rod and the second sliding sleeve to move backward through the push block, that is, at this time, the push rod will be driven to make the push sleeve move backward. When the male connector is inserted into the corresponding position, the second sliding sleeve, the push rod, and the push sleeve will move forward to return to the initial position, thus realizing the installation of the female connector and the male connector. The operation is simple and convenient, reducing the operation steps and complexity, saving time and effort, and greatly improving the connection and installation efficiency of the water inlet pipe and each branch on the common rail pipe.

The ends of each branch of the water supply pipe 2 and the end of the water inlet pipe 1 are respectively provided with a female connector 20 and a male connector 22. A push sleeve 21 is slidably provided on the female connector 20. The structure also includes: a mounting mechanism 23, which is provided on the water supply pipe 2 and is used to drive multiple male connectors 22 to be connected to the female connector 20 synchronously; a disc 24, which is provided on the male connector 22;

[0041] When connecting the water inlet pipes 1 of each cylinder liner unit to the ends of each branch of the water supply pipe 2, first connect the male connectors 22 on each water inlet pipe 1 to the installation mechanism 23. Then, by moving the installation mechanism 23, the male connector 22 and the water inlet pipe 1 can be driven to move. At this time, the male connector 22 moves towards the female connector 20 of each branch of the water supply pipe 2. The installation mechanism 23 will first drive the push sleeve 21 on the female connector 20 to move backward. During this process, the male connector 22 will gradually insert into the female connector 20. When the male connector 22 is inserted into the specified position in the female connector 20, the installation mechanism 23 will release the movement of the push sleeve 21. At this time, the push sleeve 21 will move back to its initial position, and the male connector 22 and the female connector 20 are then connected and installed together. That is, the connection of the water inlet pipe 1 of each cylinder liner unit to each branch of the water supply pipe 2 is completed, avoiding the current method of manually moving the push sleeve 21 with one hand and driving the male connector 22 to insert into the female connector 20 with the other hand. The disassembly is the same in principle, which can greatly reduce the labor intensity of the staff and save a lot of time. The operation is simple and convenient; and it can drive the connection and disassembly of the water inlet pipes 1 of multiple cylinder liner units and the corresponding branches on the water supply pipe 2 at the same time, which can further facilitate the connection and installation of the water inlet pipe 1 of the cylinder liner unit, saving a large number of steps and time, significantly improving the connection efficiency of the water inlet pipe 1 of each cylinder liner unit, with good use effect and strong practicability, and can be widely promoted and used.

[0043] When connecting the water inlet pipes 1 of each cylinder liner unit to the ends of each branch of the water supply pipe 2, first clamp the male connector 22 of the water inlet pipe 1 through the clamping member 234. Then, when moving the first sliding sleeve 232, the clamping member 234 and the male connector 22 of the water inlet pipe 1 will be driven to move. At this time, the pushing member 235 will drive the push sleeve 21 on the female connector 20 to move. When the male connector 22 moves and inserts into the specified position in the female connector 20, the pushing member 235 will release the pushing of the push sleeve 21, and the push sleeve 21 will return to its initial state, thus realizing the connection between the male connector 22 and the female connector 20; the disassembly is the same in principle. First, move the second sliding sleeve 233 to drive the pushing member 235 and the push sleeve 21 on the female connector 20 to move backward. Then, the first sliding sleeve 232 can be moved to drive the male connector 22 and the water inlet pipe 1 to be removed, and the disassembly process can be completed.

The push rods 2352 will drive the push sleeve 21 on the female joint 20 to move. When the second sliding sleeve 233 no longer moves under pressure, the second elastic member 2354 will drive the second sliding sleeve 233 to move back to the initial position, and at this time the push rods 2352 and the push sleeve 21 also return to the initial state.
