Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic hoses, in particular to a butt joint structure of a hydraulic hose and a sealing ring. Background Art

[0002] Hydraulic hose is mainly composed of liquid-resistant inner rubber layer, middle rubber layer, 2 or 4 or 6 layers of steel wire winding reinforcement layer and outer rubber layer. It has excellent oil resistance, heat resistance and aging resistance. At present, hydraulic hose is mainly used for liquid transmission in the fields of mine hydraulic support and oil field mining.

[0003] Before use, the hydraulic hose needs to use a docking structure to install the sealing structure at its port to improve the overall sealing effect, thereby facilitating subsequent installation with the interface. However, most docking structures are relatively simple and can only install a single sealing structure, reducing the overall sealing effect. Utility Model Content

[0004] To this end, the utility model provides a butt joint structure of a hydraulic hose and a sealing ring to solve the above-mentioned problems in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] According to a first aspect of the utility model, a docking structure of a hydraulic hose and a sealing ring comprises:

[0007] A first sealing ring is pasted and arranged on the inner side of the port of the hydraulic hose body, and an outer mounting tube is arranged on the outer side of the port of the hydraulic hose body, and an inner mounting tube is integrally fixedly installed on the inner side end of the outer mounting tube, and a second sealing ring is connected to the left side of the inner mounting tube;

[0008] A first sealing ring is embedded in the inner wall of the port of the hydraulic hose body, and the outer side of the first sealing ring is connected to a second sealing ring located at the inner side end of the outer mounting tube;

[0009] The reinforcing rib is integrally fixedly mounted on the inner wall end of the outer mounting tube.

[0010] Furthermore, a mounting ring located on the left side of the first sealing ring is provided at the inner end of the hydraulic hose body, and a mounting groove for mounting the second sealing ring is provided inside the mounting ring.

[0011] Furthermore, the outer wall of the hydraulic hose body is provided with a prefabricated groove, and the prefabricated groove and the reinforcing rib are arranged in a one-to-one correspondence.

[0012] Furthermore, the left end of the installation inner tube is inclined inwardly, and the inclination angle of the first sealing ring is consistent with the inclination angle of the installation inner tube.

[0013] Furthermore, a connecting ring located in the hydraulic hose body is fixedly installed inside the outer wall of the inner installation tube, and the connecting ring is in contact with the first sealing ring.

[0014] Furthermore, the first sealing ring and the second sealing ring are connected to each other in a matching manner, and the second sealing ring and the outer mounting tube are connected by gluing.

[0015] The utility model has the following advantages:

[0016] 1. Through the second sealing ring, it is convenient to install the second sealing ring inside the right side of the mounting ring through the mounting groove, so that the second sealing ring contacts the left end of the mounting inner tube, thereby facilitating preliminary sealing;

[0017] 2. Through the first sealing ring, the side wall of the installation inner tube can be connected to the first sealing ring during installation. At this time, the first sealing ring can seal the connection between the installation inner tube and the hydraulic hose body, which is convenient for relatively tight docking work, thereby further improving the overall sealing effect;

[0018] 3. The first sealing ring and the second sealing ring are connected to each other at the outside of the port of the external mounting pipe through the first sealing ring and the second sealing ring, so as to compensate for the gap between the hydraulic hose body and the external mounting pipe.
