Description

Technical Field

[0001] This utility model relates to the field of rubber hose technology, specifically a protective device for connecting rubber hoses. Background Technology

[0002] Rubber hoses are tubular products made of rubber material. They can be easily bent and twisted to adapt to various complex installation environments and angle requirements, making them very convenient for connecting equipment or pipes in different locations.

[0003] Rubber hoses are widely used in industrial production and daily life to transport various fluid media. However, during the docking process, rubber hoses are prone to leakage and rupture due to the fact that the connection points are easily subjected to external pulling and environmental factors. Therefore, it is necessary to develop a protective device for rubber hose docking to facilitate the docking of rubber hoses.

[0004] Chinese Patent Publication No. CN211821216U discloses a "Protective Device for Rubber Hose Connection," comprising a connecting collar, a sealing protection structure, and a one-way valve structure. The upper end of the connecting collar is connected to a connecting sleeve, and a connecting through hole is formed in the middle of the connecting sleeve. The sealing protection structure is located inside the lower end of the connecting collar, and the one-way valve structure is installed inside the sealing protection structure. This protective device for rubber hose connection utilizes a flexible annular connecting collar to facilitate contact between the rubber hose and the connecting collar, thus enabling easy connection between rubber hoses. The sealing protection structure effectively protects the seal at the connection point. A rubber storage track allows for easy connection of external sealant between the connecting collar and the rubber hose, thereby improving the seal at the connection point and preventing leakage. This significantly enhances the practicality of this protective device for rubber hose connection.

[0005] The aforementioned prior art, through the design of a flexible annular connecting collar, facilitates easy contact between rubber hoses, enabling seamless connection between them. The sealing protection structure protects the seal at the hose connection point, and the adhesive storage track allows for easy application of external sealant to the connecting collar and hose, thus improving the seal and preventing leakage. This significantly enhances the practicality of the rubber hose connection protection device. However, in practice, the existing device exhibits low sealing performance at the hose connection point, leading to leakage that can cause inconvenience and safety hazards in production and daily life.

A second fixing ring is installed inside the second rubber hose, and a second placement groove is opened on the second fixing ring at the corresponding position of the second sealing gasket.

[0011] As a further embodiment of this utility model: the fixing blocks are in two sets, one set of fixing blocks is installed on one side of the second rubber hose, the fixing blocks are annular structures, the first placement groove is an annular groove structure, and the first sealing gasket is an annular structure.

[0012] As a further embodiment of this utility model: a set of fixing blocks installed on one side of the second rubber hose engages with a fixing block installed on one side of the first rubber hose, and there are two sets of fixing frames, with one set of fixing frames sleeved on the outer side of the second rubber hose.

[0013] As a further embodiment of this utility model: a first fixing ring is installed on the outside of a set of fixing frames sleeved on the outside of the second rubber hose, and the bolt passes through the first fixing ring and extends to its outside.

[0014] As a further embodiment of this utility model: the inclined block is fixedly installed inside the first rubber hose, the docking ring is a ring structure, and there are multiple sets of placement chambers, which are symmetrically and evenly arranged at intervals within the docking ring.

By engaging the fixing blocks on one side of the first and second rubber hoses together, and inserting the first sealing gasket into the corresponding first placement groove, the fixing frames fitted on the first and second rubber hoses are brought together. By passing bolts through the respective first fixing rings, placing nuts on the bottom of the bolts, and tightening the nuts, the fixing blocks on one side of the first and second rubber hoses are tightly fitted together. The sealing performance is improved by the first sealing gasket being inserted into the corresponding first placement groove.

[0019] This invention, through the designed docking assembly, further improves the stability of the docking structure between the first and second rubber hoses, ensuring the stability of fluid delivery. The first and second rubber hoses are docked together, with the docking ring inserted into the second rubber hose. The second sealing gasket moves into the second placement groove, which presses against it. This movement of the second sealing gasket drives the moving rod, which in turn drives the moving block. The moving block compresses the spring, causing the second sealing gasket to press firmly against the second placement groove, reducing pipe vibration caused by external factors and ensuring the stability of fluid delivery.

[0030] like Figure 2 As shown, in this embodiment: two sets of fixing frames 204 are provided on the outer side of the first rubber hose 1 and the second rubber hose 3. A fixing frame 204 is fitted onto the outer side of each of the first rubber hose 1 and the second rubber hose 3. A first fixing ring 205 is installed on the outer side of each fixing frame 204. A bolt 206 is provided on one side of any of the first fixing rings 205. The bolt 206 passes through both first fixing rings 205 and extends to their outer sides. A nut 207 is threaded onto the free end of the bolt 206. The effect achieved by the above components is to fit the fixing frames 204 fitted onto the first rubber hose 1 and the second rubber hose 3 in a... By passing the bolt 206 through the first fixing ring 205 respectively, and putting the nut 207 on the bottom end of the bolt 206, the fixing block 201 on one side of the first rubber hose 1 and the fixing block 201 on one side of the second rubber hose 3 are tightly fitted together by tightening the nut 207.

The second placement groove 409 presses the second sealing gasket 407 to move, which in turn moves the moving rod 406. The moving rod 406 then moves the moving block 405, which compresses the spring 404. The second sealing gasket 407 is then pressed tightly against the second placement groove 409, reducing pipe vibration caused by external factors and ensuring the stability of fluid transport. When it is necessary to adjust the first rubber hose... When protecting the joint between the first rubber hose 1 and the second rubber hose 3, the fixing block 201 on one side of the first rubber hose 1 and the fixing block 201 on one side of the second rubber hose 3 are engaged together, the first sealing gasket 203 is engaged in the corresponding first placement groove 202, the fixing frames 204 respectively fitted on the first rubber hose 1 and the second rubber hose 3 are fitted together, the bolt 206 is passed through the first fixing ring 205 respectively, the nut 207 is put on the bottom end of the bolt 206, and the nut 207 is tightened to tightly fit the fixing block 201 on one side of the first rubber hose 1 and the fixing block 201 on one side of the second rubber hose 3 together, and the sealing performance is improved by the first sealing gasket 203 being engaged in the corresponding first placement groove 202.
