Description

Technical Field

[0001] This application relates to the field of hoses, and more specifically, to a hose connection and fixing device. Background Technology

[0002] Rubber hoses are a type of tubular rubber product used to transport gases, liquids, slurries, or granular materials. Rubber hose assemblies are a common auxiliary device in hydraulic systems. They are made of high-pressure steel wire braided or wound rubber hoses and steel fittings, which are crimped by special equipment. They are used to connect various hydraulic components in hydraulic systems and are mainly used to transmit hydraulic power or transport high-pressure media such as water, gas, and oil under suitable working temperature conditions to ensure the circulation of liquids and the transfer of liquid energy.

[0003] Currently, it is difficult to directly connect the hose to other equipment during the use of hoses, or when replacement is needed, a connector is required to connect the hose to other equipment or hoses. How to quickly and stably connect and fix the hose to the connector is an urgent problem to be solved. Utility Model Content

[0004] To overcome the above deficiencies, this application provides a hose connection and fixing device, which aims to improve the problems mentioned in the background art.

[0005] This application provides a hose connection and fixing device including a connector assembly and a fixing assembly.

[0006] The connector assembly includes a threaded head and a connector, with the threaded head disposed at one end of the connector.

[0007] The fixing assembly includes a pressure plate, pressure teeth, a rubber tube, a threaded tube, and a pressure sleeve. The connector has an annular groove. The pressure plate is rotatably disposed within the connector. The pressure teeth are fixedly connected to the pressure plate. The rubber tube is sleeved within the annular groove. The pressure teeth press against the rubber tube. The threaded tube is threadedly sleeved between the connector and the pressure plate. The pressure sleeve is fixedly connected to the end of the threaded tube, and the pressure sleeve cooperates with the connector to tightly press against the rubber tube.

[0008] In one specific implementation, the connector has a notch, and the pressure plate is adapted to the notch.

[0009] In the above process, by opening a notch, the pressure plate can rotate into the notch, and the inner end of the pressure plate abuts against the inner end of the notch to achieve stable fixation.

[0010] In one specific implementation, a fixing block is provided on the outside of the connector, and the pressure plate is rotatably connected to the fixing block via a rotating shaft.

[0011] In the above process, the pressure plate is rotated stably by setting a fixed block in conjunction with the rotating shaft.

[0012] In one specific implementation, the pressure plate is arc-shaped, and a plurality of pressure teeth are arranged on the inner side of the pressure plate.

[0013] In the above process, multiple pressure teeth are set up to squeeze into the tube section, thereby firmly hooking and fixing the tube.

[0014] In one specific implementation, the connector end has a tapered surface, and the inner wall of the pressure sleeve fits against the tapered surface.

[0015] In the above implementation process, by setting a conical surface, the hose can be spread along the conical surface and fitted into the annular groove when the hose is connected, and at the same time, the inner wall of the pressure sleeve can press tightly against the hose of the conical surface, further ensuring the sealing performance.

[0016] In one specific implementation, the threaded tube and the pressure sleeve are integrally formed.

[0017] In one specific implementation, the outer side of the threaded tube is provided with raised strips, and multiple raised strips are evenly arranged.

[0018] In the above implementation process, by setting multiple convex strips, it is easier to reduce the effort when rotating the threaded pipe to connect to the connector and the arc-shaped pressure plate, and ensure that the rotation is in place.

[0019] In one specific implementation, a baffle is integrally formed between the threaded head and the connector.

[0020] In the above implementation process, a baffle is set to facilitate the handling of the whole unit for connection operations.

[0021] Beneficial effects: This application provides a hose connection and fixing device. By setting a threaded head, connector, pressure plate, pressure teeth, hose, threaded tube, and pressure sleeve, the connector uses an annular groove to open the hose, and the pressure plate drives the pressure teeth to embed into the hose part for fixing. Finally, the threaded tube and pressure sleeve are screwed on. Not only does the threaded connection of the connector and pressure plate restrict the rotation of the pressure plate, but the pressure sleeve also presses the fitted hose to ensure sealing, achieving quick connection and improving practicality.

Detailed Implementation

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0030] Please see Figures 1-5 This application provides a hose connection and fixing device including a connector assembly 100 and a fixing assembly 200.

[0031] Please see Figure 1 and 2 The connector assembly 100 includes a threaded head 110 and a connector 120, with the threaded head 110 disposed at one end of the connector 120.

[0032] The connector 120 has a notch 122, and the pressure plate 210 is adapted to the notch 122. By opening the notch 122, the pressure plate 210 can rotate into the notch 122, and the inner end of the pressure plate 210 abuts against the inner end of the notch 122 to achieve stable fixation.

[0033] In one specific implementation, a baffle 130 is integrally formed between the threaded head 110 and the connector 120. By setting the baffle 130, it is convenient to pick up the whole unit for connection operation.

[0034] It should be noted that the threaded head 110 can be adapted to be connected to other equipment, or connected to another connection and fixing device by means of internal thread connection to achieve quick connection.

[0035] Please see Figure 1 , 3 4 and 5, the fixing assembly 200 includes a pressure plate 210, a pressure tooth 220, a rubber tube 230, a threaded tube 240, and a pressure sleeve 260. The connector 120 has an annular groove 121. The pressure plate 210 is rotatably disposed in the connector 120. The pressure tooth 220 is fixedly connected to the pressure plate 210. The rubber tube 230 is sleeved in the annular groove 121. The pressure tooth 220 presses against the rubber tube 230. The threaded tube 240 is threadedly sleeved between the connector 120 and the pressure plate 210. The pressure sleeve 260 is fixedly connected to the end of the threaded tube 240, and the pressure sleeve 260 cooperates with the connector 120 to tightly press against the rubber tube 230.

[0036] The connector 120 has a fixing block 123 on its outer side. The pressure plate 210 is rotatably connected to the fixing block 123 via a rotating shaft. By setting the fixing block 123 in conjunction with the rotating shaft, the pressure plate 210 can rotate stably.

[0037] Specifically, the pressure plate 210 is arc-shaped, and multiple pressure teeth 220 are arranged on the inner side of the pressure plate 210. By setting multiple pressure teeth 220, the pressure teeth 220 are used to squeeze into the part of the tube 230, thereby firmly hooking and fixing the tube 230.

[0038] In this embodiment, the connector 120 has a tapered surface 124 at its end, and the inner wall of the pressure sleeve 260 fits against the tapered surface 124. By setting the tapered surface 124, when the tubing 230 is connected, the tubing 230 can be spread along the tapered surface 124 and fitted into the annular groove 121. At the same time, the inner wall of the pressure sleeve 260 can press tightly against the tubing 230 on the tapered surface 124, further ensuring the sealing performance.

[0039] In one specific implementation, the threaded tube 240 and the compression sleeve 260 are integrally molded.

[0040] It should be noted that the threaded tube 240 is provided with a raised strip 241 on the outside. Multiple raised strips 241 are evenly arranged. By providing multiple raised strips 241, it is easier to rotate the threaded tube 240 to connect to the connector 120 and the arc-shaped pressure plate 210, and ensures that the rotation is in place.

[0041] The working principle of this hose connection and fixing device is as follows: First, rotate and remove the threaded tube 240 and pressure sleeve 260 and place them on the hose 230. Then, hold the end of the hose 230 and align it with the tapered end 124 of the connector 120, spreading the hose 230 onto the connector 120. Next, rotate the arc-shaped pressure plate 210, which drives multiple pressure teeth 220 to move. The pressure teeth 220 embed into the end of the hose 230. Finally, rotate the threaded tube 240 and pressure sleeve 260 to tighten the threaded tube 240. The threaded connection is made to the connector 120 and the arc-shaped pressure plate 210. At the same time, the inner wall of the pressure sleeve 260 can tightly press the rubber tube 230 in the conical surface 124 to ensure the sealing after the connection. The threaded connection between the arc-shaped pressure plate 210 and the inner wall of the threaded tube 240 restricts each other and improves stability. The pressure teeth 220 squeeze the part embedded in the rubber tube 230 to firmly hook and fix the rubber tube 230, realizing quick connection and improving practicality. Finally, after the connection is completed, it is connected to other equipment through the threaded head 110.

[0042] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
