Description

Technical Field

[0001] The utility model belongs to the technical field of rubber hose assemblies, in particular to a detachable rubber hose assembly which is easy to maintain. Background Art

[0002] A rubber hose assembly is a pipe fitting used to connect pipelines and convey media. It is usually composed of a rubber hose and a metal joint. It has the characteristics of high temperature resistance, corrosion resistance, and pressure resistance. It is widely used in conveying systems in the industrial field. When the rubber hose assembly is working, the connection is easily eroded by the conveyed object. When the rubber hose assembly is connected, it is clamped by a clamp and a clamp joint. During a long period of work, oil stains are easy to solidify at the connection, which makes the disassembly of the rubber hose more troublesome, resulting in reduced disassembly efficiency during assembly maintenance. Therefore, a detachable rubber hose assembly that is easy to maintain is proposed.

[0003] For example, a Chinese patent with publication number CN202252502U discloses a detachable rubber hose assembly that is easy to maintain, including four parts: a tapered pipe joint, a rubber hose, a safety pipe clamp and a clamp. The tapered pipe joint is inserted into the inner hole of the rubber hose, the safety pipe clamp is installed in the matching area between the rubber hose and the tapered pipe joint by bolts, and the clamp is also installed in the matching area between the rubber hose and the tapered pipe joint by bolts.

[0004] The existing technical documents have the following problems:

[0005] The prior art documents have some disadvantages when used, such as: when the rubber hose assembly is connected, the clamping action is performed through the clamping hoop and the clamping joint. During the long-term working process, the oil stains are easy to solidify at the connection, which makes it more troublesome to disassemble the rubber hose, resulting in reduced disassembly efficiency during assembly maintenance. Moreover, when the rubber hose assembly is working, the working environment is relatively humid and low in temperature, which easily causes erosion to the rubber hose assembly, reducing the service life of the rubber hose. In view of this, we propose a detachable rubber hose assembly that is easy to maintain. Utility Model Content

[0006] The purpose of the utility model is to provide a detachable rubber hose assembly that is easy to maintain in order to solve the above-mentioned technical problems, thereby facilitating the disassembly of the rubber hose assembly and increasing the service life of the rubber hose.

[0007] In view of this, the utility model provides a detachable rubber hose assembly which is easy to maintain, comprising a wear-resistant sleeve, and also comprising: an anti-cracking layer is fixedly provided on the inner wall of the wear-resistant sleeve, a steel layer is fixedly provided on the inner wall of the anti-cracking layer, a fire-blocking layer is fixedly provided on the inner wall of the steel layer, a buffer layer is fixedly provided on the inner wall of the fire-blocking layer, a fixed sleeve is sleeved on the surface of the wear-resistant sleeve, a connecting pipe is fixedly installed on one side of the wear-resistant sleeve, a connecting head is fixedly installed on one side of the connecting pipe, a sealing gasket is fixedly installed on the other side of the inside of the connecting head, an internal threaded sleeve is fixedly provided on the inner wall of the connecting head, threaded grooves are fixedly provided on both ends of the connecting head, a clamping seat is sleeved on the surface of the connecting head, and clamping bolts are installed through both ends of the clamping seat.

[0008] Based on the above structure, through the coordinated use of the internal threaded sleeve, the clamp and the threaded groove, the rubber hose assembly can be easily disassembled and installed, and the connecting head can be maintained. The anti-crack layer can prevent the hose from cracking or bursting under high pressure, and then the wear-resistant sleeve can be used to increase the corrosion capacity of the rubber hose surface, and then the steel bar layer can be used to improve the strength and stability of the rubber hose.

[0009] Preferably, an inner braided layer is fixedly provided on the inner wall of the buffer layer, and a corrosion-resistant layer is fixedly provided on the inner wall of the inner braided layer, so that the corrosion-resistant layer can reduce the damage to the inner wall of the hose caused by the transported object.

[0011] Preferably, a limiting sleeve is fixedly installed on the bottom of the fixing sleeve, a limiting bolt is installed through the surface of the limiting sleeve, a connecting rod is installed through the bottom of the limiting sleeve, and the limiting bolt is used to facilitate the connection between the connecting rod and the limiting sleeve.

[0012] Preferably, a base is fixedly installed at the bottom of the connecting rod, and a fixing bolt is installed through the top of the base, and the fixing bolt is used to install the base.

Then, the connector is provided with an internal thread sleeve to facilitate the connection with other pipes. Then, the connector is limited after the connection through the cooperation of the clamping bolt and the thread groove, thereby improving the stability of the connection. The cooperation of the internal thread sleeve, the clamping bolt and the thread groove facilitates the disassembly and installation of the rubber hose assembly, and the connector can be maintained, thereby improving the convenience of using the connector.

[0017] 2. The detachable rubber hose assembly which is easy to maintain is installed and set up by the wear-resistant sleeve for the anti-cracking layer, the steel layer, the fire-blocking layer and the buffer layer. The anti-cracking layer is then used to prevent the hose from cracking or bursting under high pressure. The wear-resistant sleeve is then used to increase the erosion capacity of the rubber hose surface. The steel layer is then used to improve the strength and stability of the rubber hose. The fire-blocking layer is then used to prevent the spread of fire. The buffer layer plays a protective and shock-absorbing role, which can reduce the damage to the hose caused by external impact, thereby reducing the erosion of the rubber hose by humid and low-temperature environments and increasing the service life of the rubber hose.
