Fig. 2 is a schematic structural view of a portion a in fig. 1.

In the figure: the device comprises a pull rod 1, a gun barrel 2, an oil storage cavity 3, a sealing leather cup 4, an extension tube 5, an oil scraping sleeve 6, a gun head 7, a limiting ring 8, a bolt 9, a spring 10 and a clamping block 11.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.

As shown in figures 1-2, a lubricating oil injection device comprises a gun barrel 2, a gun head 7 and a pull rod 1 which are respectively in threaded connection with two ends of the gun barrel 2, wherein the gun head 7 is provided with an oil filling nozzle and a handle, the inner wall of the gun barrel 2 is in sliding connection with a telescopic pipe 5, one end of the telescopic pipe 5, which is close to the pull rod 1, is fixedly sleeved with a sealing leather cup 4, the two sealing leather cups 4 are in sliding sealing connection with the inner wall of the gun barrel 2, an oil storage cavity 3 is formed between the two sealing leather cups 4 and the gun barrel 2, a countersunk hole is arranged at one end of the side wall of the gun barrel 2 close to the gun head 7, a bolt 9 is connected with the inner wall of the countersunk hole in a threaded manner, and the inner wall of the counter sink is connected with a clamping block 11 in a sliding way, a spring 10 is fixedly connected between the clamping block 11 and the bolt 9 together, one end of the clamping block 11 far away from the spring 10 is propped against the side wall of the extension tube 5, and a clamping groove matched with the clamping block 11 is formed at one end, close to the sealing leather cup 4, of the outer side wall of the telescopic pipe 5.

Adopt above-mentioned scheme, flexible pipe 5 inserts and sucks the operation in the lubricating oil to be stained with flexible pipe 5 final shrink that is full of lubricating oil and keep apart with external world in advancing barrel 2, thereby can not make dirty workman's gloves, also can not bring impurity into the oil drum, cause the lubricating oil pollution.

The inner wall of the gun head 7 is fixedly connected with a limiting ring 8 communicated with the oil filling nozzle, the inner wall of the limiting ring 8 is fixedly connected with a sealing ring, and the sealing ring is tightly matched with the telescopic pipe 5 to prevent lubricating oil from leaking out of the gun head 7 when the grease gun is filled with grease.

The one end of barrel 2 is still fixedly connected with scrapes oil cover 6, scrapes oil cover 6 and is the elasticity material, and scrapes oil cover 6 and the lateral wall slip of flexible pipe 5 and cup joints, when in flexible pipe 5 withdrawal barrel 2, scrapes the outside glutinous lubricating oil that glues of flexible pipe 5, prevents that too much lubricating oil from getting into in the barrel 2.

The length of the telescopic pipe 5 is 30-60 mm, so that the volume occupied in the gun barrel 2 is reduced under the condition that lubricating oil can be pumped.

The working principle is as follows: when lubricating oil needs to be filled, the gun head 7 is unscrewed, the pull rod 1 is pushed to the bottom, the telescopic pipe 5 extends out of the gun barrel 2 under the pushing of the pull rod 1, air in the gun barrel 2 is removed, meanwhile, the clamping groove in the telescopic pipe 5 is clamped with the clamping block 11, the telescopic pipe 5 is fixed at the tail end of the gun barrel 2, negative pressure can be formed when the pull rod 1 sucks, the telescopic pipe 5 cannot retract into the gun barrel 2 under the negative pressure, then the telescopic pipe 5 is inserted into the lubricating oil, the pull rod 1 is pulled, the lubricating oil is sucked into the oil storage cavity 3, after enough lubricating oil is sucked, the telescopic pipe 5 is jacked by the gun head 7, the telescopic pipe 5 retracts into the gun barrel 2, the gun head 7 is screwed at last.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications fall within the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
