Description

Technical Field

[0001] The utility model belongs to the technical field of pipe connection, and particularly relates to a hose and joint connection structure. Background Art

[0002] The hose and the joint need to be connected by a nut. During the connection process, it is impossible to intuitively judge whether the nut and the joint are tightened. Once it is not completely tightened, it will cause sealing problems during the later use of the pipe fittings, and serious problems such as leakage may even occur. Some even require detection settings to detect each joint, which takes a lot of time and effort. Therefore, the problem of whether the existing joints and nuts are installed in place needs to be improved. Utility Model Content

[0003] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of the utility model is to provide a hose and joint connection structure, which has a simple structure, reasonable design, and is easy to assemble. By arranging a gasket between the joint and the nut, the problem of whether the nut and the joint are connected in place is well solved.

[0004] Technical solution: In order to achieve the above-mentioned purpose, the utility model provides a hose and joint connection structure, including: a joint, a washer and a nut, wherein the washer is arranged on the joint, and the nut is arranged on the outside of the washer and connected to the joint, and a group of protrusions are circumferentially arranged at one end of the nut close to the washer. The hose and joint connection structure described in the utility model has a simple structure, reasonable design, and is easy to assemble. By arranging a washer between the joint and the nut, when the nut is tightened during the process of screwing the nut and the joint, its protrusion will exert pressure on the washer to deform the washer, indicating that the nut and the joint are tightened, so that the staff can judge more intuitively, which well solves the problem of whether the nut and the joint are connected in place.

[0005] The washer includes a ring body and an extension, wherein the ring body is sleeved on the joint, and the extension is arranged on a side of the ring body close to the nut, and the diameter of the extension is larger than the hole diameter of the nut. The setting of the extension can effectively improve the stability of its setting, prevent the nut from being screwed over, and can play a certain role in limiting the nut.

[0006] The joint is provided with a retaining ring at one end of the washer away from the nut, and the diameter of the retaining ring is larger than the diameter of the ring body. The setting of the retaining ring can play a certain role in limiting the washer to prevent it from moving with the nut, thereby further improving the stability of the connection between the nut and the joint.

[0007] The connector is provided with at least one connection end, and the provision of at least one connection end allows the number of connection ends to be selected according to the actual needs of the user.

[0008] The joint is provided with a groove for installing a gasket, and a stopper is provided at one end of the groove close to the nut.

[0009] The inner side of the gasket is provided with a lower convex portion, and the lower convex portion cooperates with the stopper. The arrangement of the lower convex portion and the stopper can play a good role in limiting the gasket, preventing it from moving other than deformation, and further ensuring the intuitiveness of the detection of the connection tightness.

[0010] It also includes an insertion bead and a hose, one end of the insertion bead is inserted into the hose, and the other end is connected to the joint.

[0011] The connector is T-shaped and has three connection ends, each of which is provided with a gasket. The arrangement of multiple connection ends on the T-shaped connector allows it to meet the needs of connecting multiple hoses.

[0012] The outer circumference of the nut is provided with an anti-skid texture, which can effectively alleviate the problem of slipping during the tightening process of the nut.

[0013] It can be seen from the above technical solution that the utility model has the following beneficial effects:

[0014] 1. The hose and joint connection structure described in the utility model has a simple structure, reasonable design and is easy to assemble. By arranging a gasket between the joint and the nut, when the nut and the joint are screwed, when the nut is tightened, its protrusion will exert pressure on the gasket to deform the gasket, indicating that the nut and the joint are tightened, so that the staff can judge more intuitively, which well solves the problem of whether the nut and the joint are connected in place.

[0015] 2. The gasket described in the utility model includes a ring body and an extension. The setting of the extension can effectively improve the stability of its setting, prevent the nut from being screwed over, and play a certain limiting role on the nut.

[0016] 3. The setting of the retaining ring in the utility model can play a certain limiting role on the gasket, preventing it from moving with the nut, thereby further improving the stability of the connection between the nut and the joint.

[0017] 4. The joint described in the utility model is provided with a retaining ring at one end of the washer away from the nut. The setting of the lower protrusion and the stopper can play a good limiting role on the washer, avoiding it from making other movements besides deformation, and further ensuring the intuitiveness of the detection of the connection tightness.
