Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic hoses, in particular to a quick-change hydraulic hose connector. Background Technique

[0002] Hydraulic rubber hoses, also known as hydraulic oil pipes, hydraulic hoses, high-pressure rubber hoses, hydraulic pipes, steel wire high-pressure pipes, steel wire braided rubber hoses, and steel wire wound rubber hoses, are generally divided into steel wire braided hydraulic rubber hoses and steel wire wound hydraulic rubber hoses. Hydraulic hoses mainly consist of a liquid-resistant inner rubber layer, a middle rubber layer, a steel wire winding reinforcement layer, and an outer rubber layer. The inner rubber layer enables the conveying medium to bear pressure and protects the steel wire from erosion. The outer rubber layer protects the steel wire from damage, and the steel wire layer is the framework material that plays a reinforcing role.

[0003] Existing, such as an adjustable hydraulic hose connector in Application No.: 201721070176.X, includes a connector core tube body, a first sealing groove, a first sealing gasket, a limit sleeve, a second sealing groove, a second sealing gasket, and a check ring. The utility model can adjust the length of the hydraulic hose connector through the insertion end, can meet the installation requirements of special connection positions. The third sealing gasket, the fourth sealing gasket, and the sealing ring at the port of the insertion end ensure the sealing performance of the connection, and the insertion end is detachable. When some parts are damaged, it is convenient to disassemble for repair and replacement; through the gradually shrinking chamfered cylindrical structure at the port of the hydraulic hose connection end, the fit between the connecting hose and the port changes from a free state to a pressed state, eliminating stress concentration and making the connection between the hose and the connector core more convenient; the barb on the check ring prevents the hose from falling off, ensuring the sealing performance and reliability of the connection, with convenient installation and not prone to faults such as leakage due to mistakes.

[0004] During the use of the above application, the hose connector is directly fixed at the connection end of the hose. When it is damaged and cannot be used, the connector cannot be quickly replaced. Therefore, we propose a quick-change hydraulic hose connector to solve the problems raised above. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem in the prior art that the hose connector is directly fixed at the connection end of the hose and cannot be quickly replaced when it is damaged and cannot be used, and to propose a quick-change hydraulic hose connector.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A quick-change hydraulic hose connector includes an overall structure and a connection component, and the connection component is located at the center of the outer surfaces on both sides of the overall structure;

[0007] The overall structure includes a joint body and a first connecting plate. On both sides of the inner top and inner bottom of the first connecting plate, sliding rods are fixedly connected at the front and rear positions. The extending ends of the sliding rods are fixedly connected with fixing clips. A compression spring is sleeved on the outer surface of the sliding rods. A rubber gasket is fixedly connected at the center of the inner surface of the fixing clip. Electric push rods are fixedly installed on both sides of the top and bottom of the joint body. The extending ends of the electric push rods are fixedly connected with connecting rods. The extending ends of the connecting rods are fixedly connected with movable plates. Second connecting plates are fixedly connected to the top and bottom of the front and rear outer surfaces of the first connecting plate.

[0008] Preferably, plugs are penetrated through the outer surfaces of both sides of the joint body near the center, and sealing rings are fixedly connected to the outer surfaces of both sides of the joint body.

[0009] Preferably, one end of the compression spring is fixedly connected to the outer surface of the first connecting plate, and the other end of the compression spring is fixedly connected to the outer surface of the fixing clip.

[0010] Preferably, the outer surfaces of the fixing clip and the rubber gasket are slidably connected to the outer surfaces of the sealing ring and the hose body, and the outer surfaces of the movable plate and the connecting rod are slidably connected to the outer surface of the first connecting plate.

[0011] Preferably, a guide rod is slidably connected to the inner surface of the second connecting plate.

[0012] Preferably, bolts are threadedly penetrated through the top of the front and rear outer surfaces of the fixing clip. Threaded holes are provided at the positions of the bolts on the top of the fixing clip. The inner wall of the threaded hole is threadedly connected to the outer surface of the bolt.

[0013] Preferably, the connecting component includes a hose body, and a receiving end is arranged on the inner surface of the hose body.

[0014] Preferably, the inner surface of the receiving end is slidably connected to the inner surfaces of the sealing ring and the plug.

[0015] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0016] 1. In the present utility model, when it is necessary to disassemble the connector after long-term use, the user only needs to screw out a plurality of bolts. Then, the compression spring loses its restraint, enabling the fixing clip and the rubber washer to separate from the hose body, and the disassembly is completed. The disassembly process is relatively simple, so that each subsequent disassembly and assembly will not take too much time. When installation is required, the electric push rod retracts, driving the connecting rod and the movable plate to move downward, so that the movable plate can contact the outer surface of the first connecting plate. When contacting, the first connecting plate is forced to move downward, and the sliding rod and the compression spring change their states under the force and transmit the force to the fixing clip. Then, the fixing clip and the rubber washer can fully contact the outer surfaces of the sealing ring and the hose body, and fixation can be completed through the cooperation of the bolts and the threaded holes.

[0017] 2. In the present utility model, through the setting of the rubber washer, the sealing performance at the connection between the fixing clip and the hose and the sealing ring can be increased. Through the setting of the sealing ring, the sealing performance at the connection between the plug and the hose body and the receiving end can be improved. Through the mutual cooperation of the guide rod and the second connecting plate, the stability of the two first connecting plates during up and down movement is realized, so as to ensure that the subsequent disassembly and assembly operations can be carried out normally.

[0023] To better understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0024] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0025] Embodiment 1, as Figures 1 - 4 shown, a quick-change hydraulic hose connector includes an overall structure 1 and a connection assembly 2, and the connection assembly 2 is located at the center of the outer surfaces on both sides of the overall structure 1; the overall structure 1 includes a connector body 101 and a first connecting plate 102. Slide rods 103 are fixedly connected to the front and rear positions on both sides of the inner top and inner bottom of the first connecting plate 102. A fixed clamp 107 is fixedly connected to the extended end of the slide rod 103. A compression spring 104 is sleeved on the outer surface of the slide rod 103. A rubber gasket 108 is fixedly connected to the center of the inner surface of the fixed clamp 107. Electric push rods 115 are fixedly installed on both sides of the top and bottom of the connector body 101. A connecting rod 114 is fixedly connected to the extended end of the electric push rod 115. A movable plate 113 is fixedly connected to the extended end of the connecting rod 114. Second connecting plates 112 are fixedly connected to the top and bottom of the front and rear outer surfaces of the first connecting plate 102.

[0026] The overall effect achieved by the entire Embodiment 1 is, as Figure 1 and Figure 3 shown, when the bolt 109 is subsequently unscrewed, the compression spring 104 loses its restraint, then rebounds, and drives the fixed clamp 107 to move, so that the fixed clamp 107 and the rubber gasket 108 can be separated from the hose body 201. After separation, the user can manually move the two hose bodies 201 to both sides, so that the two receiving ends 202 are separated from the plug 106, and the separation completes the disassembly. The disassembly method is relatively simple, making it convenient for the user to perform better each time.

[0027] Embodiment 2, as Figures 1 - 4As shown, plugs 106 are penetrated through the outer surfaces of both sides of the joint body 101 near the center. Sealing rings 105 are fixedly connected to the outer surfaces of both sides of the joint body 101. One end of the compression spring 104 is fixedly connected to the outer surface of the first connecting plate 102, and the other end of the compression spring 104 is fixedly connected to the outer surface of the fixing clip 107. The outer surfaces of the fixing clip 107 and the rubber washer 108 are slidably connected to the outer surfaces of the sealing ring 105 and the hose body 201. The outer surfaces of the movable plate 113 and the connecting rod 114 are slidably connected to the outer surface of the first connecting plate 102. A guide rod 111 is slidably connected to the inner surface of the second connecting plate 112. Bolts 109 are penetrated through the top of the front and rear outer surfaces of the fixing clip 107. Threaded holes 110 are formed at the positions of the bolts 109 on the top of the fixing clip 107. The inner wall of the threaded hole 110 is threadedly connected to the outer surface of the bolt 109. The connecting component 2 includes a hose body 201. A receiving end 202 is arranged on the inner surface of the hose body 201. The inner surface of the receiving end 202 is slidably connected to the inner surfaces of the sealing ring 105 and the plug 106.

[0028] The effect achieved by the entire embodiment 2 is that through the setting of the sealing ring 105, the sealing performance at the joints of the plug 106 with the receiving end 202 and the hose body 201 can be increased. Through the mutual cooperation of the second connecting plate 112 and the guide rod 111, the stability of the first connecting plate 102 during up and down movement can be improved, and it is ensured that the first connecting plate 102 can only move up and down in the vertical direction. Through the mutual cooperation of the bolt 109 and the threaded hole 110, multiple fixing clips 107 can be restricted to ensure that the fixing clips 107 can be stably located on the hose body 201, and indirectly, it also ensures that the joint body 101 can be stably located between the two hose bodies 201.

[0029] Working principle: During installation, the user first aligns the receiving ends 202 on the two hose bodies 201 with the plugs 106 on both sides of the joint body 101. After alignment, they can be brought closer to insert the plugs 106 on both sides into the receiving ends 202. Through the setting of the sealing ring 105, the sealing performance of the connection can be improved. After connection, the electric push rod 115 retracts, driving the connecting rod 114 and the movable plate 113 to move downward. When the movable plate 113 moves downward to a certain position, it will contact the outer surface of the first connecting plate 102. Then the first connecting plate 102 is forced to move downward, and its sliding rod 103 and compression spring 104 change their states. The fixing clip 107 is also forced to move closer to the connection between the hose body 201 and the sealing ring 105. After moving closer and fitting together, the fixing clip 107 uses the expansion force of the compression spring 104 to make it contact more tightly with the outer surfaces of the hose body 201 and the sealing ring 105, ensuring that the joint body 101 can be stably located between the two hose bodies 201. Then the user screws the bolt 109 into the corresponding threaded hole 110. Screwing it in realizes the restriction of the fixing clip 107 and indirectly restricts the compression spring 104. Then the movable plate 113 and the connecting rod 114 are reset by the electric push rod 115, and thus the connection between the joint body 101 and the two hose bodies 201 is completed. After long-term use, when the joint body 101 needs to be replaced, the user only needs to unscrew the bolt 109, so that the compression spring 104 loses its restraint. Through the rebound of the compression spring 104, the fixing clip 107 is driven to separate from the two hose bodies 201. After separation, the user then pulls the hose bodies 201 to both sides to separate the receiving ends 202 from the plugs 106 and the sealing ring 105. After separation, the separation of the hose body 201 from the joint body 101 is completed. The disassembly and assembly process is relatively simple, so that not much time will be spent on subsequent disassembly and assembly each time.

[0030] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
