Description

Technical Field

[0001] This utility model relates to the field of hydraulic hose technology, and in particular to a hydraulic hose with anti-leakage function at the connection. Background Technology

[0002] Hydraulic hoses, also known as hydraulic oil pipes, hydraulic flexible hoses, high-pressure hoses, hydraulic tubes, steel wire high-pressure hoses, steel wire braided hoses, and steel wire spiral hoses, are generally divided into steel wire braided hydraulic hoses and steel wire spiral hydraulic hoses. In the prior art, two adjacent hydraulic hoses are connected by a connecting pipe head and a sealing ring. The connection method using a single sealing ring has an unsatisfactory sealing effect and poses a risk of leakage at the connection point during use. Therefore, this application proposes a hydraulic hose with a leakage-proof function at the connection point. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hydraulic hose with a leak-proof connection.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A hydraulic hose with a leak-proof connection function includes two hydraulic hose bodies, and a leak-proof connection mechanism is installed between the two hydraulic hose bodies.

[0006] The leak-proof connection mechanism includes:

[0007] A sealing connection assembly is fixedly sleeved on two hydraulic hose bodies, and the sealing connection assembly achieves a seal between the two hydraulic hose bodies.

[0008] The wrapping and sealing component is fitted onto the sealing connection component, and the wrapping and sealing component is used to seal and wrap the sealing connection component.

[0009] The locking mechanism is fixedly connected to the front side of the package sealing assembly, and the package sealing assembly is secured by the locking mechanism.

[0010] Preferably, the sealing connection assembly includes two connecting pipes, which are sealed and fixedly sleeved on the corresponding hydraulic hose bodies. An annular groove is provided on the outer side of the connecting pipe, and the two annular grooves are both open on the side close to each other. A first sealing ring is bonded and fixed on the side close to each other of the two connecting pipes, and the two first sealing rings are in close contact on the side close to each other. A T-shaped screw is rotatably installed on the inner wall of the right annular groove, and the connecting pipe on the left is screwed onto the two T-shaped screws. By setting the T-shaped screws, the distance between the two connecting pipes can be adjusted, thereby effectively squeezing and fitting the two first sealing rings together.

[0011] Preferably, the sealing assembly includes two semi-circular tubes movably fitted within two annular grooves, with the rear sides of the two semi-circular tubes rotatably mounted, forming a complete circular tube. A semi-circular airbag is bonded and fixed inside each semi-circular tube, and an L-shaped connecting pipe is fixedly connected to the left side of the semi-circular airbag. A valve is installed on the L-shaped connecting pipe. The two semi-circular airbags form a complete circular airbag, and a semi-circular sealing ring is bonded and fixed to the inner side of each semi-circular airbag. The semi-circular airbags are designed to compress the semi-circular sealing rings during inflation. The inner side of the semi-circular sealing rings is in close contact with the inner walls of the two annular grooves, and also in close contact with the outer sides of the two first sealing rings. The connection between the two first sealing rings is wrapped by the two semi-circular sealing rings.

[0012] Preferably, the locking mechanism includes two fixing blocks. The rear side of the fixing block is fixedly connected to the front side of the corresponding semi-circular tube. The upper fixing block has a slot on its right side, in which a locking block is movably fitted. The slot and the locking block cooperate to restrict the two fixing blocks, thereby achieving a fixed connection between the two semi-circular tubes. The lower fixing block has a rectangular groove on its right side, in which an L-shaped rod is slidably fitted. A spring is fixedly connected between the left end of the L-shaped rod and the left inner wall of the rectangular groove. The right inner wall of the L-shaped rod is fixedly connected to the right side of the locking block. A pull ring is fixedly connected to the right side of the L-shaped rod.

[0013] Preferably, each of the two connecting pipes has a groove communicating with its interior on the side away from each other. The inner wall of the groove is fixedly connected to the outer side of the corresponding hydraulic hose body. A second sealing ring is glued and fixed at the end of the two hydraulic hose bodies that are close to each other. The side of the two second sealing rings that are close to each other is glued and fixed to the inner wall of the side of the two grooves that are close to each other. By setting the second sealing ring, the risk of leakage at the connection between the hydraulic hose body and the connecting pipe is reduced.

The inner side of the inner ring of the bearing is fixedly connected to the outer side of the corresponding T-shaped screw. The bearings serve to allow the corresponding T-shaped screw to rotate and be installed. Two threaded holes are provided on the inner wall of the left side of the annular groove on the left side. The threaded holes are threadedly connected to the corresponding T-shaped screw. The threaded connection between the threaded holes and the T-shaped screw allows the connecting pipe on the right side to move while rotating.

[0015] Preferably, the two semi-circular tubes are threaded together on the rear side with the same hinge, and the two semi-circular tubes are installed by rotating the hinge.

[0016] Compared with existing technologies, the beneficial effects of this utility model are:

[0017] 1. By setting up the sealing connection component, a sealed connection between the two hydraulic hose bodies can be achieved. The T-shaped screw inside the sealing connection component allows the distance between the two connecting pipes to be adjusted, thereby enabling the compression of the two first sealing rings and improving their sealing fit.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-5A hydraulic hose with a leak-proof connection function includes two hydraulic hose bodies 1, and a leak-proof connection mechanism is installed between the two hydraulic hose bodies 1.

[0028] Leak-proof connection mechanisms include:

[0029] The sealing connection assembly 2 is fixedly sleeved on the two hydraulic hose bodies 1;

[0030] The sealing connection assembly 2 includes two connecting pipes 201, which are sealed and fixedly sleeved on the corresponding hydraulic hose bodies 1. Each of the two connecting pipes 201 has a groove communicating with its interior on the side furthest from each other. The inner wall of the groove is fixedly connected to the outer side of the corresponding hydraulic hose body 1. A second sealing ring is bonded and fixed to the end of each of the two hydraulic hose bodies 1 closest to each other. The side of each of the two second sealing rings closest to each other is bonded and fixed to the inner wall of the side of each of the two grooves closest to each other. The second sealing rings reduce the risk of leakage at the connection between the hydraulic hose body 1 and the connecting pipes 201. An annular groove 202 is formed on the outer side of each connecting pipe 201. The side of each of the two annular grooves 202 closest to each other is open. A first sealing ring 204 is bonded and fixed to the side of each of the two connecting pipes 201 closest to each other. The side of each of the two first sealing rings 204 is in close contact. The sealing ring 204 achieves a sealed connection between the two connecting pipes 201. A T-shaped screw 203 is rotatably installed on the inner right side of the annular groove 202 on the right side. The connecting pipe 201 on the left side is threaded onto the two T-shaped screws 203. Two bearing holes are opened on the right side of the annular groove 202 on the right side. Bearings are fixedly sleeved in the bearing holes. The inner side of the inner ring of the bearing is fixedly connected to the outer side of the corresponding T-shaped screw 203. The bearings serve to allow the corresponding T-shaped screw 203 to be rotated and installed. Two threaded holes are opened on the inner left side of the annular groove 202 on the left side. The threaded holes are threadedly connected to the corresponding T-shaped screw 203. The threaded connection between the threaded holes and the T-shaped screw 203 allows the connecting pipe 201 on the right side to move while rotating, thereby adjusting the distance between the two connecting pipes 201 and effectively squeezing and fitting the two first sealing rings 204.

[0031] The sealing assembly 3 includes two semi-circular tubes 303 movably fitted within two annular grooves 202. The rear sides of the two semi-circular tubes 303 are rotatably mounted, and the rear sides of the two semi-circular tubes 303 are threadedly fixed to the same hinge. The two semi-circular tubes 303 are rotatably mounted via the hinge, forming a complete circular tube. A semi-circular airbag 302 is bonded and fixed inside each semi-circular tube 303. An L-shaped connecting pipe 304 is fixedly connected to the left side of the semi-circular airbag 302. A valve is installed on the L-shaped connecting pipe 304, which connects to an external air supply pipe, thereby allowing air to pass through. Air is supplied to the semi-circular airbag 302 through the L-shaped connecting pipe 304. The two semi-circular airbags 302 form a complete circular airbag. A semi-circular sealing ring 301 is bonded and fixed to the inner side of the semi-circular airbag 302. The semi-circular airbag 302 is designed to compress the semi-circular sealing ring 301 when it is inflated. The inner side of the semi-circular sealing ring 301 is in close contact with the inner wall of the two annular grooves 202. The inner side of the semi-circular sealing ring 301 is also in close contact with the outer side of the two first sealing rings 204. The connection between the two first sealing rings 204 is wrapped by the two semi-circular sealing rings 301.

[0032] The locking mechanism 4 includes two fixing blocks 401. The rear side of the fixing block 401 is fixedly connected to the front side of the corresponding semi-circular tube 303. The upper fixing block 401 has a slot 402 on its right side, in which a locking block 406 is movably fitted. The slot 402 and the locking block 406 cooperate to restrict the two fixing blocks 401, thereby achieving a fixed connection between the two semi-circular tubes 303. The lower fixing block 401 has a rectangular groove 403 on its right side, in which an L-shaped rod 404 is slidably fitted. The bottom inner wall of the rectangular groove 403 has a limit hole, and the bottom of the L-shaped rod 404 is fixed. A limiting block is fixedly connected to a limiting hole, and the limiting block and the limiting hole cooperate to limit and prevent the L-shaped rod 404 from detaching. A spring 405 is fixedly connected between the left end of the L-shaped rod 404 and the left inner wall of the rectangular groove 403. The right inner wall of the L-shaped rod 404 is fixedly connected to the right side of the locking block 406. A pull ring is fixedly connected to the right side of the L-shaped rod 404. Through a series of structural settings, this utility model can achieve effective sealing between the two hydraulic hose bodies 1 by squeezing and wrapping the connection of the two first sealing rings 204, thereby improving the sealing effect and achieving the purpose of preventing leakage.

[0033] Working principle: With the two hydraulic hose bodies 1 in an unconnected state, during connection, first pull the pull ring to the right. The pull ring drives the L-shaped rod 404 to move to the right. The L-shaped rod 404 slides to the right within the rectangular groove 403 and stretches the spring 405. The L-shaped rod 404 drives the locking block 406 to move out of the locking groove 402, releasing the mutual restriction between the two semi-circular tubes 303. Rotate the two semi-circular tubes 303 in a direction away from each other, and fit the two semi-circular tubes 303 into the annular groove 202 on the left. After half-rotating the two semi-circular tubes 303, when the outer diameter of the two semi-circular tubes 303 is smaller than the distance between the two T-shaped screws 203, the connection is complete. The first sealing ring 204 on the right is inserted into the two semi-circular sealing rings 301, and the two T-shaped screws 203 are rotated in the forward direction. As the T-shaped screws 203 rotate, they are screwed into the corresponding threaded holes. The two T-shaped screws 203 are rotated and moved to the left in the corresponding threaded holes. The two T-shaped screws 203 simultaneously drive the connecting pipe 201 on the right to move to the left. The connecting pipe 201 on the right drives the first sealing ring 204 on the right to move to the left until it is in close contact with the first sealing ring 204 on the left. Thus, the two hydraulic hose bodies 1 are sealed together through the two first sealing rings 204.

[0034] Next, continue rotating the two semicircular tubes 303 until their sides are in close contact. Then, release the tension on the pull ring. At this point, the elastic force of the spring 405, which is under tension, drives the locking block 406 into the locking groove 402 through the L-shaped rod 404, thereby achieving mutual restraint between the two fixing blocks 401 and the two semicircular tubes 303. At this time, the two first sealing rings 204 are wrapped between the two semicircular sealing rings 301. Then, connect the L-shaped connecting pipe 304 to the external air supply pipe, open the valve, and allow gas to enter the opposite side through the L-shaped connecting pipe 304. As the gas inside the semi-circular airbag 302 increases, it gradually expands, compressing the corresponding semi-circular sealing ring 301 under the expansion force. The semi-circular sealing ring 301 compresses the first sealing ring 204, so that the inner sides of the two semi-circular sealing rings 301 are tightly fitted with the connection between the two first sealing rings 204. At this time, the two semi-circular sealing rings 301 tightly seal and wrap the connection between the two first sealing rings 204. By tightly sealing and wrapping, the connection is further sealed, which can effectively reduce the risk of leakage at the connection.

[0035] Simultaneously, the T-shaped screw 203 allows the distance between the two connecting pipes 201 to be adjusted, thereby compressing the two first sealing rings 204, improving their sealing fit, and thus achieving the effect of preventing leakage.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
