Description

Technical Field

[0001] The utility model belongs to the technical field of jacks, and particularly relates to a jack with a self-lubricating structure. Background Technique

[0002] A jack refers to a light lifting device that uses a rigid lifting piece as a working device to jack up heavy objects within a small stroke through a top bracket or a bottom pawl. Jacks are mainly used in factories, mines, transportation and other departments for vehicle repair and other lifting and supporting work. They are light, strong, flexible and reliable, and can be carried and operated by one person.

[0003] The following problems exist in the application of the existing jacks on the market:

[0004] 1. During the actual use of traditional jacks, usually the structure of their hydraulic telescopic rods is exposed, which causes external dust and fine particles to easily adhere to them during use, resulting in unsmooth lifting and requiring lubrication operations by staff, so the operation is relatively troublesome during implementation.

[0005] 2. When most jacks are in use, the hydraulic telescopic rod structure during idle time often does not have an additional protection structure. During use or transportation, once it is impacted or dropped to the ground, the hydraulic telescopic rod is easily stressed, which will affect the tightness of the connection between the telescopic rod structure and the cylinder, so the protection effect is poor during application. Content of the Utility Model

[0006] The purpose of the utility model is to provide a jack with a self-lubricating structure to solve the technical problems raised in the background technique.

[0007] To achieve the above purpose, the specific technical solution of the utility model is as follows: A jack with a self-lubricating structure includes a cylinder and a hydraulic telescopic rod. The top of the cylinder is provided with a hydraulic telescopic rod. The bottom of the cylinder is provided with a base. The top of the base is provided with a pump body. The top of the pump body is provided with a plunger rod. The outside of the hydraulic telescopic rod is sleeved with an oil storage tank. A filter screen plate is inlaid inside the oil storage tank. The filter screen plate is distributed in a ring shape. The top of the oil storage tank is connected to a feed pipe. The top of the feed pipe is provided with a sealing plug. The top of the sealing plug is connected to a spherical pull rod.

[0008] Preferably, the outside of the cylinder is connected to a first vertical plate and a second vertical plate through a turntable seat. The first vertical plate and the second vertical plate are symmetrically distributed. A metal rod is arranged inside the first vertical plate. A reinforcing rod is arranged inside the second vertical plate. The top of the reinforcing rod is connected to a limiting plate.

[0009] Preferably, a positioning groove is formed at the top of the cylinder, a positioning rod is provided at the bottom of the fuel tank, and the positioning rod is embedded inside the positioning groove.

[0010] Preferably, a perforation is formed inside the first vertical plate, a metal rod is provided inside the perforation, a magnetic attraction groove is formed on the side of the reinforcing rod, and the metal rod is inserted inside the magnetic attraction groove.

[0011] Preferably, a support rod is provided at the top of the base, a mounting seat is provided at the top of the plunger rod and the support rod, and a strip-shaped plate is provided at the top of the mounting seat.

[0012] Preferably, a strip-shaped hole is formed inside the strip-shaped plate, the strip-shaped plate is connected to the mounting seat through a rotating shaft, and an operating rod is provided on the outer side of the strip-shaped plate.

[0013] The jack with a self-lubricating structure of the present invention has the following advantages:

[0014] 1. For the jack with a self-lubricating structure, by providing structures such as a fuel tank, a filter screen plate, a feed pipe, and a sealing plug outside the hydraulic telescopic rod, the effect of self-lubrication can be achieved. In order to make the telescopic rod structure exposed outside more lubricated during telescoping, the fuel tank is installed outside the hydraulic telescopic rod. The staff opens the sealing plug at the top of the feed pipe and directly pours the lubricating oil into the fuel tank. Since the filter screen plate is installed inside, when the hydraulic telescopic rod telescopes, the lubricating oil will directly flow to the outside of the telescopic rod, so the effect of self-lubrication can be achieved during use, and the operation is relatively simple.

[0015] 2. For the jack with a self-lubricating structure, by installing structures such as a first vertical plate, a second vertical plate, a reinforcing rod, a limiting plate, and a metal rod outside the hydraulic telescopic rod, the top of the hydraulic telescopic rod can be protected. In order to better protect the hydraulic telescopic rod at the top of the cylinder, first rotate the first vertical plate and the second vertical plate, then push the reinforcing rod and the limiting plate inside the first vertical plate, take out the metal rod and penetrate it through the inside of the second vertical plate, so that the metal rod is inserted inside the reinforcing rod, and thus the protection structure can be fixed at the top of the hydraulic telescopic rod, and the protection effect is stronger during application.

[0034] Working principle of the self-lubricating structure jack: When using this jack, first, the position of the jack body needs to be moved, and it is taken and moved by the user. After moving to the designated position, it is placed on the ground, and then the jack device can be used. Since the hydraulic telescopic rod 4 at the top of the cylinder 2 is directly exposed outside during operation, and there are some dust and fine particles in the air, to avoid affecting the use of the hydraulic telescopic rod 4 at the top of the cylinder 2, a fuel tank 19, a filter plate 22, a feed pipe 23, and a sealing plug 24 are provided outside the hydraulic telescopic rod 4.

Secondly, a through hole 16 is opened inside the second vertical plate 13, and a metal rod 17 is embedded in the through hole 16. Then the metal rod 17 is inserted into the magnetic attraction groove 18 on the side of the reinforcing rod 14, so that the protection structure can be fixed on the top of the hydraulic telescopic rod 4, and the protection effect is strong during application. When it is needed to use, the metal rod 17 is pulled in the reverse direction and the limiting rod is dragged outward. Finally, the hydraulic telescopic rod 4 can be used for work. A pump body 3 and a support rod 6 are provided on the top of the base 1. An installation seat 7 is provided on the top of the pump body 3 and the support rod 6, and the installation seat 7 is connected to a strip plate 8 outside the strip hole 9 through a shaft rod.
