Description

Technical Field

[0001] The utility model relates to the technical field of oil injection joints, in particular to an expandable oil injection joint. Background Art

[0002] During the use of some mechanical equipment, it is often necessary to inject oil into the equipment to ensure its normal operation. When injecting oil into mechanical equipment, an oil injector is usually used.

[0003] When the existing oil injector injects oil into mechanical equipment, it usually sleevs the hose on the mechanical equipment over the surface of the connecting pipe on the oil injection joint. Then, the oil injector transports the internal oil to the inside of the mechanical equipment through the oil injection joint, the connecting pipe and the hose. And different mechanical equipment can be simultaneously connected through multiple connecting pipes on the oil injection joint for oil injection to achieve the effect of expanding oil injection. It not only has high oil injection efficiency but also can accurately control the oil injection volume. However, since the oil and gas mixture filled during oil injection by the oil injector is at high pressure, and the existing oil injection joint lacks a structure for strengthening the hose, it may cause the oil and gas mixture to impact the inner wall of the hose during oil injection, resulting in the hose being separated from the connecting pipe and affecting the normal transportation. Summary of the Utility Model

A rectangular frame is fixedly connected to one side of the circular ring. A plurality of threaded holes are opened on one side of the rectangular frame. Two bolts are threadedly connected to the inner walls of the plurality of threaded holes. Two circular hole blocks are symmetrically and slidably connected to the inner wall of the rectangular frame. The size and shape of the surface of the bolt are adapted to the size and shape of the inner wall of the circular hole block. L-shaped rods are fixedly connected to one side of both circular hole blocks. Arc-shaped plates are fixedly connected to the adjacent sides of the two L-shaped rods.

[0006] The effects achieved by the above components are as follows: By setting the limiting device, first manually move the two L-shaped rods, so that the two L-shaped rods drive the two arc-shaped plates to move towards each other, and the two L-shaped rods drive the two round-hole blocks to move towards each other along the inside of the rectangular frame. When the two arc-shaped plates move to the position where they simultaneously squeeze the surface of the hose sleeved on the connecting pipe, the inner wall of the round-hole block coincides with the inner wall of any threaded hole. At this time, turn the bolts with tools, so that the two bolts are respectively inserted into the inside of the two round-hole blocks and the corresponding threaded holes, so that the two bolts fix the two round-hole blocks, and then achieve the position fixation of the two arc-shaped plates, so that the two arc-shaped plates limit and intercept the hose by squeezing the hose, reducing the situation that the hose is separated from the connecting pipe due to the impact force generated during oil injection after the hose is connected to the connecting pipe, and improving the connection stability between the hose and the connecting pipe.

[0007] Preferably, a plurality of rubber strips are fixedly connected to the adjacent sides of the two arc-shaped plates, and the plurality of rubber strips are arranged at equal distances.

[0010] The effects achieved by the above components are as follows: By setting the support block, the support block can reinforce the L-shaped rod, improve the strength of the L-shaped rod, and reduce the situation of shaking of the L-shaped rod during use.

[0011] Preferably, a positioning rod is fixedly connected to the inner wall of the rectangular frame, and positioning holes are formed in one side of the two round-hole blocks, and the surface of the positioning rod is slidably connected to the inner walls of the two positioning holes.

[0012] The effects achieved by the above components are as follows: By setting the positioning rod and the positioning holes, the positioning rod can be located inside the two positioning holes to assist in limiting the two round-hole blocks, reducing the situation of left and right shaking when the two round-hole blocks move towards each other inside the rectangular frame.

The surface of the sealing plate is larger than the inner wall of the connecting pipe. One side of the sealing plate is fixedly connected to a rectangular plate. The surface of the rectangular plate is larger than the inner wall of the rectangular groove. One side of the rectangular plate is fixedly connected to a screw hole block. A screw is threadedly connected to the inner wall of the screw hole block. One end of the screw is rotatably connected to the surface of the joint body close to the rectangular groove.

When the sealing plate moves to a position where it is completely inserted into the inside of the rectangular groove, the sealing plate closes the position at the inlet of the connecting pipe, preventing the oil inside the joint body from entering the corresponding connecting pipe, enabling personnel to freely control the oil output of multiple connecting pipes, and improving the convenience and flexibility of using the connecting pipe.

[0017] Preferably, one end of the screw away from the joint body is fixedly connected to a screwing block, and a plurality of grooves are formed on the surface of the screwing block.
