Description

Nitrogen tank universal joint suitable for hydraulic equipment

Technical Field

The utility model relates to a hydraulic equipment field especially relates to a nitrogen gas jar universal joint suitable for hydraulic equipment.

Background

At present, hydraulic equipment usually uses a nitrogen tank, an air compressor and the like as air source power. The connector used by the existing nitrogen tank cannot be suitable for various types of gas valves. When the air valve is damaged, if the air valve with the same diameter cannot be found, the air valve cannot be replaced in a short time, or resource waste is possibly caused, for example, the whole nitrogen tank needs to be adjusted or directly replaced. In addition, the connector on the existing market can not make up for the precision error generated by the connection between the air valve and the nitrogen tank.

Therefore, those skilled in the art have been devoted to developing a universal joint which is suitable for various types of gas valves, has good sealing performance and can compensate for accuracy errors.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned defect of prior art, the utility model aims to solve the technical problem how to provide the air valve that is applicable to multiple model, the leakproofness is good and can compensate the universal joint of precision error.

In order to achieve the aim, the utility model provides a nitrogen tank universal joint suitable for hydraulic equipment, which comprises a first joint component, a second joint component, a sealing ring, a fastener, a rubber pad with threads and a rotatable connecting piece,

the first joint part is connected with the second joint part, the rotatable connecting piece is arranged between the first joint part and the second joint part, the first joint part can rotate relative to the second joint part, the sealing ring is positioned at the other end of the first joint part, the fastening piece is positioned on the side wall of the first joint part, the depth of the fastening piece entering the inner cavity of the first joint part is adjusted by rotating or pressing the fastening piece, and the rubber gasket with threads is attached to the inner wall of the second joint part.

Furthermore, the sealing ring is composed of a base body and an edge body, wherein the edge body is positioned at one end of the base body and extends out of the base body.

Furthermore, the elasticity of the edge body is larger than that of the base body.

Further, the first fitting component has threads on a sidewall thereof for mating with the fastener.

Further, the first joint member forms an angle of not more than 30 ° with the second joint member by the rotatable connection.

Technical effects

The edge body of the sealing ring used by the utility model is easy to bend and deform when being extruded by the pipe diameter because of larger elasticity, so that the large pipe diameter enters the inner cavity of the first joint component, and the bending part can be tightly attached to the side wall of the pipe diameter, thereby providing the installation performance for the air valves with different pipe diameters and having good sealing effect;

the fastener is used for fixing the air valve entering the inner cavity of the first joint part, and the depth of the fastener entering the inner cavity is adjusted by rotating or pressing the fastener, so that the air valve is convenient to fix;

the inner wall of the second joint part is attached to the rubber pad with the threads, so that the service life of the second joint part is prolonged;

the angle of the first joint part relative to the second joint part is not more than 15 degrees, which is beneficial to reducing precision errors generated by connection between a product and equipment.

The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.

Drawings

Fig. 1 is a schematic view of the overall structure of a universal joint according to a preferred embodiment of the present invention;

fig. 2 is a schematic view of a sealing ring according to a preferred embodiment of the present invention.

Detailed Description

The technical contents of the preferred embodiments of the present invention will be more clearly understood and appreciated by referring to the drawings attached to the specification. The present invention may be embodied in many different forms of embodiments, and the scope of the invention is not limited to the embodiments described herein.

As shown in FIG. 1, a nitrogen gas tank universal joint suitable for a hydraulic apparatus includes a first joint member 1, a second joint member 2, a seal ring 3, a fastener 4, a rubber gasket 5 having a thread, and a rotatable joint member 6. The first joint member 1 and the second joint member 2 communicate with each other. The inner diameter of first coupling member 1 is not greater than the inner diameter of second coupling member 2. A rotatable connection 6 is arranged between the first joint part 1 and the second joint part 2. The first joint member 1 is rotatable relative to the second joint member 2. The angle formed by the first joint part 1 and the second joint part 2 under the effect of the rotatable connection does not exceed 15 deg. It is substantially ensured that the first joint part 1 and the second joint part 2 are on the same central axis on a naked eye. The seal ring 3 is located at the other end of the first joint member 1. The specific location of the sealing ring 3 is not limited herein and the sealing ring 3 can be disposed anywhere within the interior cavity of the first fitting component 1, but does not restrict the movement of the fastener 4. The fastener 4 is located on a side wall of the first fitting part 1. The depth of the fastener 4 into the interior cavity of the first fitting component 1 is adjusted by rotating or depressing the fastener. The present embodiment is rotated, that is, the side wall of the first joint member 1 is provided with a thread matching with the fastening member 4, where the fastening member 4 can be a bolt, a nut, etc. The air valve is fixed by adjusting the depth of the fastener 4 entering the inner cavity. A rubber pad 5 with a screw thread is attached to the inner wall of the second joint member 2. The inlet pipe diameter of nitrogen gas jar and the cooperation of rubber pad 5 with the screw thread, one has reduced gas leakage, and the second makes the life-span extension of second joint part 2.

The sealing ring 3 consists of a base body 31 and a rim body 32. The edge body 32 extends from the base body 31. As shown in fig. 2, the thickness of the base body 31 is much greater than that of the edge body 32. The elasticity of the edge body 32 is greater than that of the base body 31. The edge body 32 is easily bent and deformed when being squeezed by the pipe diameter, so that the large pipe diameter enters the inner cavity of the first joint member, and the bent portion is closely attached to the side wall of the pipe diameter.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the teachings of this invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
