Embodiment Construction

[0016] A non-return filter device for a grease gun, comprising a non-return filter inner chamber 1 threadedly connected with a gun head of the grease gun, a non-return device and a filter screen 2 arranged in the non-return filter inner chamber.

[0017] The filter screen is conical, which can increase the filtering area, and the non-return device is placed on the left side of the filter screen.

[0018] The other end of the non-return filter cavity is threadedly connected with an oil pipe 3, and one end of the oil tube extends into the non-return filter cavity and is threadedly connected with it, and the other end is threadedly connected with a tapered oil nozzle 4.

[0019] The non-return device is made of perforated spacer 5, spring 6, non-return ball 7.

[0020] One end of the spring is against the oil pipe port placed in the inner cavity of the non-return filter, and the non-return ball is clamped between the other end of the spring and the spacer with holes, and the diam...

Abstract

The invention discloses a non-returning and filtering device for a grease gun, and belongs to the technical field of oil injection tools. The non-returning and filtering device comprises a non-returning and filtering inner cavity in threaded connection with a grease gun head, a non-returning device arranged in the non-returning and filtering inner cavity, and a filtering net arranged in the non-returning and filtering inner cavity. The other end of the non-returning and filtering inner cavity is connected with an oil pipe in a threaded manner. One end of the oil pipe stretches into the non-returning and filtering inner cavity and is in threaded connection with the non-returning and filtering inner cavity, and an oil injection nozzle is in threaded connection to the other end of the oil pipe. The non-returning device is composed of a spacer with a hole, a spring and a non-returning ball. One end of the spring abuts against an oil pipe port located in the non-returning and filtering inner cavity, and the non-returning ball is clamped between the other end of the spring and the spacer with the hole. The non-returning and filtering device is reasonable in structure and easy to manufacture. The problems of oil leakage and oil returning of the grease gun are solved through the additionally-arranged lubricating oil non-returning device, and the problem of blockage of the grease gun head is solved through the filtering net. The non-returning and filtering device is wide in application range, easy to operate, convenient to carry, wide in application range and capable of improving the work efficiency.

Description

technical field [0001] The invention relates to a non-return filter device for a grease gun, which can prevent lubricating oil from flowing back and the head of the grease gun from being blocked, and belongs to the technical field of oiling tools. Background technique [0002] A grease gun is a hand tool used to grease mechanical equipment. When it is filled with grease, the source of grease is mainly from the mandrel circulating back and forth in the pump body, and the butter is first sucked into the pump body and then pressurized into the hose. Working for a long time will easily cause the lubricating oil in the gun head to flow back, causing oil leakage and blockage. In addition, after long-term use, the nozzle of the grease gun is easily blocked by debris in the grease. The above problems will affect work efficiency, waste time, bring great inconvenience to work, and sometimes cause waste of resources. Contents of the invention [0003] The object of the present inv...
