Description

Technical Field

[0001] This utility model belongs to the field of hose connection technology, and in particular relates to a hydraulic hose connection structure. Background Technology

[0002] Hydraulic hoses are flexible pipes used in hydraulic systems to transport high-pressure liquids (such as oil and water). Their main function is to transmit hydraulic power or media and ensure the stable operation of the hydraulic system under complex working conditions. When installing hydraulic hoses, because the material of hydraulic hoses is relatively soft, the existing technology uses a hollow cone at the end of the connection structure used for hydraulic hose installation to facilitate the insertion of various hydraulic hoses and the flow of internal fluid. However, because the surface of the cone is relatively smooth, it may detach when the pressure inside the hydraulic hose is high, resulting in high-pressure fluid leakage.

[0003] Therefore, how to provide a hydraulic hose connection structure is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulic hose connection structure to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows: a hydraulic hose connection structure, comprising; Connectors; A connecting cone is fixedly installed on the inner side of the top of the connector; The lower connecting end is fixedly installed at the bottom of the connector; A flexible hose end, which is inserted into the surface of a connecting cone; A fastening structure is provided at the outer end of the top of the connector, which, in conjunction with the connecting cone, reinforces the end of the hose.

[0006] Preferably, the lower connecting end is provided with a pressure sealing structure, which includes a pressure rod, a rubber ring and an airbag ring. The rubber ring is placed on the inner side of the bottom of the lower connecting end, and the airbag ring is fixedly installed inside the rubber ring. The pressure rod is circumferentially arranged at the lower end of the inner side of the lower connecting end and movably abuts against the inner end of the airbag ring.

[0007] Preferably, the fastening structure includes a positioning ring plate, a rotating component, a through groove, a top plate, a pressure plate, a return spring, and a traction ring. The positioning ring plate is fixedly installed on the outer side of the top of the connector. The rotating component is movably installed on the outer side of the positioning ring plate. The traction ring is slidably disposed at the bottom of the rotating component. The through groove is circumferentially arrayed on the surface of the positioning ring plate. The top plate is disposed at the upper end of the through groove. The pressure plate is slidably and hingedly disposed at the lower end of the through groove and hinged to the inner side of the traction ring. The return spring array is disposed at the bottom of the inner side of the pressure plate and is fixedly connected to the top of the connector.

[0008] Preferably, the pressure bar is an L-shaped plate, which increases the contact area with the liquid. The greater the liquid flow velocity inside the connector, the greater the drop height of the pressure bar.

[0009] Preferably, the lower end of the top plate is inclined outward, and the pressure plate rotates inward when it contacts the top plate.

[0010] Preferably, the upper end of the positioning ring plate is provided with a thread and is movably connected to the inner side of the rotating part, and the lower end of the positioning ring plate is provided with a sliding groove and is slidably connected to the inner side of the traction ring.

[0011] Preferably, the return spring pushes upward, thereby causing the pressure plate to rotate outward and reset when the traction ring descends.

[0012] Compared with the prior art, the beneficial effects of this utility model are: during use, by setting a fastening structure at the top edge of the connector and cooperating with the connecting cone on the inner side of the top of the connector, the hose end is not easy to separate from the connecting cone, thereby reinforcing the hose end from the outside, further enhancing the stability of the hose end and preventing the hose end from detaching due to excessive pressure. Meanwhile, by setting a pressure sealing structure inside the lower connection end at the bottom of the connector, the sealing degree of the gap between the lower connection end and the pipe connection will change with the flow rate and volume of the high-pressure liquid when it is being transported, so as to avoid the internal liquid from leaking from the connection between the lower connection end and the pipe when transporting high-pressure liquid.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The diagram shown is a structural schematic of a hydraulic hose connection structure provided in one embodiment of the present invention, comprising: Connector 1; Connecting cone 3 is fixedly installed on the inner side of the top of connector 1; Lower connecting end 2 is fixedly installed at the bottom of connector 1; The flexible hose end 4 is inserted into the surface of the connecting cone 3; The fastening structure is located at the outer end of the top of the connector 1, and reinforces the hose end 4 with the cooperation of the connecting cone 3.

[0020] In this embodiment of the utility model, when in use, the hose end 4 is installed on the connecting cone 3, and then the connector 1 is installed at the pipe opening through the lower connecting end 2, so that the hose end 4 can be installed on the connecting cone 3 and reinforced with a fastening structure; By setting a fastening structure at the top edge of the connector 1 and cooperating with the connecting cone 3 on the inner side of the top of the connector 1, the hose end 4 is not easy to separate from the connecting cone 3, thereby reinforcing the hose end 4 from the outside, further enhancing the stability of the hose end 4 and preventing the hose end 4 from detaching due to excessive pressure.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the lower connecting end 2 is provided with a pressure sealing structure. The pressure sealing structure includes a pressure rod 11, a rubber ring 12 and an airbag ring 13. The rubber ring 12 is placed on the inner side of the bottom of the lower connecting end 2, and the airbag ring 13 is fixedly installed inside the rubber ring 12. The pressure rod 11 is circumferentially arranged at the lower end of the inner side of the lower connecting end 2 and is in movable contact with the inner end of the airbag ring 13.

[0022] In this embodiment of the utility model, when in use, when conveying high-pressure liquid, the high-pressure liquid will continuously contact the top of the pressure rod 11, thereby causing the pressure rod 11 to move downward under pressure, thereby applying pressure to the airbag ring 13, causing the airbag ring 13 to move downward and expand, thereby further sealing the gap between the bottom connecting end 2 of the connector 1 and the pipe, so as to enhance its sealing performance. By setting a pressure sealing structure inside the lower connecting end 2 at the bottom of the connector 1, the sealing degree of the gap between the lower connecting end 2 and the pipe connection will change with the flow rate and flow of the high-pressure liquid when it is being transported, so as to avoid the leakage of internal liquid from the lower connecting end 2 and the pipe connection when transporting high-pressure liquid.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment of this utility model, the fastening structure includes a positioning ring plate 5, a rotating component 6, a through groove 7, a top plate 8, a pressure plate 9, a return spring 10, and a traction ring 14. The positioning ring plate 5 is fixedly installed on the outer side of the top of the connecting component 1. The rotating component 6 is movably installed on the outer side of the positioning ring plate 5. The traction ring 14 is slidably disposed at the bottom of the rotating component 6. The through groove 7 is circumferentially arranged on the surface of the positioning ring plate 5. The top plate 8 is disposed at the upper end of the through groove 7. The pressure plate 9 is slidably and hingedly disposed at the lower end of the through groove 7 and is hinged to the inner side of the traction ring 14. The return spring 10 is arranged in an array at the bottom of the inner side of the pressure plate 9 and is fixedly connected to the top of the connecting component 1.

[0024] In this embodiment of the utility model, when the rotating member 6 rotates and rises, it will simultaneously drive the traction ring 14 to slide and rise from bottom to top. When the traction ring 14 rises, it will drive the pressure plate 9, which is hinged at the lower end of the through groove 7 on the surface of the positioning ring plate 5, to rise and then abut against the inner side of the bottom of the top plate 8 at the upper end of the through groove 7 on the surface of the positioning ring plate 5. Under the constraint of the top plate 8, the pressure plate 9 rotates inward and then abuts against the end of the hose 4 inserted on the connecting cone 3. By setting a fastening structure, the connecting cone 3 can be abutted, thereby further enhancing the stability of the hose end 4 and preventing the hose end 4 from detaching due to excessive pressure.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, in a preferred embodiment of this utility model, the pressure rod 11 adopts an L-shaped plate, thereby increasing the contact area with the liquid. The greater the liquid flow velocity inside the connector 1, the greater the descent height of the pressure rod 11.

[0026] In this embodiment of the utility model, when in use, by adopting an L-shaped plate for the pressure rod 11, the contact area with the liquid is increased, and thus the greater the liquid flow velocity inside the connector 1, the greater the drop height of the pressure rod 11.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the lower end of the top plate 8 is inclined outward, and the pressure plate 9 rotates inward when it comes into contact with the top plate 8.

[0028] In this embodiment of the utility model, when in use, the lower end of the top plate 8 is tilted outward, and then when the pressure plate 9 contacts the top plate 8, it rotates inward to reinforce the hydraulic hose.

[0029] like Figure 3 As shown, in a preferred embodiment of the present invention, the upper end of the positioning ring plate 5 is provided with a thread and is movably connected to the inner side of the rotating part 6, and the lower end of the positioning ring plate 5 is provided with a sliding groove and is slidably connected to the inner side of the traction ring 14.

[0030] In this embodiment of the utility model, when in use, the upper end of the positioning ring plate 5 is provided with a thread, which is movably connected to the inner side of the rotating member 6, and the lower end of the positioning ring plate 5 is provided with a sliding groove, which is slidably connected to the inner side of the traction ring 14. Thus, when the rotating member 6 rotates and rises, it drives the traction ring 14 to slide upward.

[0031] like Figure 2 and Figure 3As shown, in a preferred embodiment of the present invention, the reset spring 10 pushes upward, thereby causing the pressure plate 9 to rotate outward and reset when the traction ring 14 descends.

[0032] In this embodiment of the invention, when in use, by pushing the return spring 10 upward, the traction ring 14 descends, and the pressure plate 9 rotates outward to reset, which facilitates the disassembly of the hydraulic hose.

[0033] The present invention provides a hydraulic hose connection structure in the above embodiments. When in use, the hose end 4 is inserted into the connecting cone 3 at the top of the connector 1, and then the rotating part 6 on the outside of the positioning ring plate 5 at the top edge of the connector 1 is rotated, so that the rotating part 6 moves upward around the thread on the outside of the positioning ring plate 5. When the rotating part 6 rotates and rises, it simultaneously drives the traction ring 14 to slide and rise from bottom to top. When the traction ring 14 rises, it drives the pressure plate 9, which is hinged at the lower end of the through groove 7 on the surface of the positioning ring plate 5, to rise and then abut against the inner side of the bottom of the top plate 8 at the upper end of the through groove 7 on the surface of the positioning ring plate 5. Under the constraint of the top plate 8, the pressure plate 9 rotates inward and then abuts against the hose end 4 inserted on the connecting cone head 3, thereby further strengthening the stability of the hose end 4 and preventing the hose end 4 from detaching due to excessive pressure. When conveying high-pressure liquid, the high-pressure liquid will continuously contact the top of the pressure rod 11, which will cause the pressure rod 11 to move downward under pressure, thereby putting pressure on the airbag ring 13. As a result, the airbag ring 13 moves downward and expands, thereby further sealing the gap between the bottom connecting end 2 of the connector 1 and the pipeline, so as to enhance its sealing performance.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
