Description

Technical Field

[0001] This utility model relates to the field of hose connector technology, specifically a crimp-type hydraulic hose connector. Background Technology

[0002] Hydraulic hoses are mainly composed of a liquid-resistant inner rubber layer, a middle rubber layer, 2, 4, or 6 layers of steel wire spiral reinforcement, and an outer rubber layer. In the oil delivery pipelines of engineering machinery equipment such as excavators, road rollers, loaders, or forklifts, or oil pumps, hose connectors are generally used, especially high-pressure hose connectors, to connect the hose to the engineering machinery equipment or oil pump. One end of the hose connector is connected to the hose, and the other end is connected to the plug fitting of the oil delivery hose of the engineering machinery equipment or oil pump.

[0003] According to a crimp-type hydraulic hose connector (announcement number: CN222067908U) published in the above application, the hose can be fixed inside the connector body by setting the crimp ring, which prevents the hose from falling off the connector body and avoids leakage.

[0004] However, in actual use, the pressure ring of the above-mentioned equipment is sleeved on the outside of the water pipe and connecting pipe. It is fixed by squeezing the hose with a clamp to generate compression deformation. Under continuous high pressure, the long-term wear of the contact between the hydraulic hose and the pressure ring will also lead to a decrease in the sealing of the connection between the two. At the same time, it will also make the hydraulic water pipe slip off the connector, reducing the safety of the hydraulic hose joint. In view of this, we propose a crimp-type hydraulic hose joint. Utility Model Content

[0005] The purpose of this invention is to provide a crimp-type hydraulic hose connector to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crimp-type hydraulic hose connector, including a connector head, the end of which is threaded with a spiral connector, and a retracting component is provided on the outer side of the connector head;

[0007] The converging assembly includes an annular groove formed on the arc-shaped outer wall of the connector. Arc-shaped protrusions are fixedly installed on the inner surfaces of both sides of the annular groove. An adjustable clamp is fitted on the outer side of the annular groove. An arc-shaped opening is formed on the arc-shaped inner surface of the adjustable clamp. A fixing ring is fixedly installed on the arc-shaped outer wall of the connector. An arc-shaped ring is fixedly installed on the outer wall of the fixing ring near the annular groove. An arc-shaped groove is formed on the outer surface of the connector away from the spiral connector. A converging ring groove is formed on the outer surface of the arc-shaped groove. An oblique hole is formed on the inner wall of the connector away from the spiral connector.

[0008] Preferably, the outer diameter of the connector is larger than the inner diameter of the hydraulic hose, so that when the hydraulic hose is inserted into the connector, the end of the hydraulic hose will tend to expand due to the influence of the connector.

[0009] Preferably, the width of the annular groove is adapted to the width of the adjustable clamp, and the adjustable clamp is fitted onto the outside of the annular groove during use.

[0010] Preferably, the number of arc-shaped protrusions and arc-shaped openings are provided in several groups, and the several groups of arc-shaped protrusions and arc-shaped openings are arranged in a circumferential array on the inner surface of the annular groove and the adjustable clamp respectively. The width of the arc-shaped protrusions is smaller than the width of the arc-shaped openings, so that the hydraulic hose part can cooperate with the arc-shaped openings to achieve the effect of positioning and preventing slippage of the hydraulic hose.

[0011] Preferably, the arc-shaped ring is provided with an inclined surface that is thinner near the annular groove and thicker near the fixed ring, so that when the hydraulic hose and the connector are installed together, the end of the hydraulic hose eventually fits against the side of the fixed ring.

[0012] Preferably, the concave surface of the arc-shaped groove is positioned facing the center of the connector, so that when the hydraulic hose is installed with the connector, the inner surface of the hydraulic hose can fit against the outer surface of the arc-shaped groove.

[0013] Preferably, the inclined hole is inclined with its bottom end close to the center of the connector and its top end away from the center of the connector, so that the bottom end of the inclined hole is away from the water-facing surface inside the connector, and the medium flowing inside the connector will not directly rush into the inclined hole. Due to the high flow velocity inside the connector, a negative pressure is generated inside the inclined hole, and the hydraulic hose fits into the arc-shaped groove near the top of the inclined hole.

[0014] Compared with the prior art, the present invention provides a crimp-type hydraulic hose connector, which has the following advantages:

[0015] 1. This crimp-type hydraulic hose connector, through the inclusion of a tightening component, allows the connection between the hydraulic hose and the connector to form a concave limiting portion through the cooperation of the adjustable clamp's inner arc-shaped opening and arc-shaped protrusion. Simultaneously, several small intervals separated by arc-shaped protrusions and arc-shaped openings are created. These intervals are relatively independent, preventing the lateral spread of even minor leaks and avoiding large-area leakage at the hose connector. Furthermore, the sealing of the hydraulic hose end by the fixing ring and arc-shaped ring prevents moisture or other liquids from entering the connection between the hydraulic hose and the connector, thus avoiding corrosion or leakage of the hydraulic hose and improving the service life and performance of the hose connector.

[0016] 2. This crimp-type hydraulic hose connector features an arc-shaped groove and an oblique hole at the end of the connector, along with a manifold groove. Due to the high flow velocity within the connector, negative pressure is generated within the oblique hole, and the hydraulic hose adheres to the arc-shaped groove near the top of the oblique hole. This creates an adsorption force on the inner surface of the hydraulic hose, causing it to fit more tightly against the end surface of the connector and preventing leakage at the hose connector joint.

[0017] 3. Due to the through-hole and manifold groove of this crimp-type hydraulic hose connector, even if the water pressure inside the hydraulic hose is too high and some water flows into the gap between the hydraulic hose and the arc groove, this part of the water will still flow back into the inner cavity of the connector due to the suction force generated by the rapid water flow inside the connector, reducing the possibility of leakage of the hydraulic hose connector.

[0022] like Figures 1-3 As shown, this utility model provides a technical solution: a crimp-type hydraulic hose connector, including a connector 1, with a spiral connector 2 threadedly connected to the end of the connector 1, and a gathering component 3 provided on the outer side of the connector 1. The gathering component 3 includes an annular groove 31, an arc-shaped protrusion 32, an adjustable clamp 33, an arc-shaped opening 34, a fixing ring 35, an arc-shaped ring 36, an arc-shaped groove 37, a manifold groove 38, and an oblique hole 39.

[0023] In one embodiment of this utility model, an annular groove 31 is formed on the arc-shaped outer wall of the connector 1. Arc-shaped protrusions 32 are fixedly installed on the inner surfaces of both sides of the annular groove 31. An adjustable clamp 33 is sleeved on the outer side of the annular groove 31. An arc-shaped opening 34 is formed on the arc-shaped inner surface of the adjustable clamp 33. A fixing ring 35 is fixedly installed on the arc-shaped outer wall of the connector 1. An arc-shaped ring 36 is fixedly installed on the outer wall of the fixing ring 35 near the annular groove 31. An arc-shaped groove 37 is formed on the outer surface of the end of the connector 1 away from the spiral connector 2. A confluence ring groove 38 is formed on the outer surface of the arc-shaped groove 37. An oblique hole 39 is formed on the inner wall of the end of the connector 1 away from the spiral connector 2.

[0024] Furthermore, the spiral joint 2 is used to connect with the pipeline of the machine equipment, and the end of the spiral joint 2 is provided with a sealing ring and a rubber gasket for sealing, to ensure the sealing performance when the spiral joint 2 is connected to the pipeline of the machine equipment. At the same time, the inner diameter of the spiral joint 2 is adapted to the inner diameter of the connector 1, so that when the spiral joint 2 and the connector 1 are connected, a stable passage can be maintained for the transportation of the medium. Specifically, the outer diameter of the connector 1 is larger than the inner diameter of the hydraulic hose, so that when the hydraulic hose is inserted into the connector 1, the end of the hydraulic hose will be affected by the connector 1 and tend to expand.

[0025] Furthermore, the width of the annular groove 31 is adapted to the width of the adjustable clamp 33. During use, the adjustable clamp 33 is fitted over the outside of the annular groove 31, and the hydraulic hose is inserted between the adjustable clamp 33 and the annular groove 31. At this point, the adjusting bolt at the bottom of the adjustable clamp 33 is tightened, thereby tightening the adjustable clamp 33 and pressing the hydraulic hose outside the annular groove 31 into the interior of the annular groove 31. Specifically, several sets of arc-shaped protrusions 32 and arc-shaped openings 34 are provided, and these sets of arc-shaped protrusions 32 and arc-shaped openings 34 are arranged in a circumferential array. On the inner surfaces of the annular groove 31 and the adjustable clamp 33, the width of the arc-shaped protrusion 32 is smaller than the width of the arc-shaped opening 34, so that the hydraulic hose portion in contact with the arc-shaped protrusion 32 can cooperate with the arc-shaped opening 34 to position and prevent slippage of the hydraulic hose. Furthermore, several sets of arc-shaped protrusions 32 and arc-shaped openings 34 can divide the contact portion between the hydraulic hose and the annular groove 31 into several small intervals. These small intervals are relatively independent, so that even if a small leak occurs, it will not expand laterally and cause a large-area leak at the hose joint.

[0026] Meanwhile, the arc-shaped ring 36 is set with an inclined surface that is thinner near the annular groove 31 and thicker near the fixed ring 35. So when the hydraulic hose is connected to the connector 1, the end of the hydraulic hose is finally in contact with the side of the fixed ring 35. At this time, the arc-shaped ring 36 fills the gap between the end of the hydraulic hose and the outer surface of the connector 1. Since the outer diameter of the connector 1 is larger than the inner diameter of the hydraulic hose, the hydraulic hose itself always has a tightening tendency during connection. With the setting of the arc-shaped ring 36, the end of the hydraulic hose can be sealed and protected, preventing moisture or other liquids in the external environment from entering the connection between the hydraulic hose and the connector 1, thereby causing corrosion or leakage of the hydraulic hose, and improving the service life and performance of the hose connector.

[0027] In this embodiment of the invention, the concave surface of the arc groove 37 is set towards the center of the connector 1, so that when the hydraulic hose is installed with the connector 1, the inner surface of the hydraulic hose can fit against the outer surface of the arc groove 37. Specifically, multiple sets of inclined holes 39 are arranged in a circumferential array on the arc-shaped inner wall of the connector 1, and the inclined holes 39 are connected to the manifold groove 38. At the same time, the inclined holes 39 are inclined in a way that the bottom end is close to the center of the connector 1 and the top end is far away from the center of the connector 1, so that the bottom end of the inclined holes 39 is far away from the water-facing surface inside the connector 1. The medium flowing inside the connector 1 will not directly rush into the inclined holes 39. Due to Bernoulli's principle, the flow velocity inside the connector 1 is relatively fast, which generates negative pressure inside the inclined holes 39. The hydraulic hose fits against the arc groove 37 near the top end of the inclined holes 39, thereby generating an adsorption force on the inner surface of the hydraulic hose, causing the hydraulic hose to fit more tightly against the end surface of the connector 1, preventing leakage at the hose joint connection.

[0028] It is worth noting that even if the water pressure inside the hydraulic hose is too high, and some water flows into the gap between the hydraulic hose and the arc groove 37, the water will still flow back into the inner cavity of the connector 1 due to the suction force generated by the rapid water flow inside the connector 1, thus reducing the possibility of leakage of the hydraulic hose joint.

[0029] In this invention, during use, the end of the hydraulic hose is aligned with the end of the connector 1, and while it is being fitted onto the connector 1, it is continuously pushed towards the fixing ring 35 until the end of the hydraulic hose is in contact with the end surface of the fixing ring 35. At this point, the adjustable clamp 33 is fitted onto the outside of the annular groove 31, and the adjusting bolt at the bottom of the adjustable clamp 33 is rotated to tighten the adjustable clamp 33 on the annular groove 31, thereby fixing the hydraulic hose to the end of the connector 1. Then, the spiral connector 2, which is connected to the pipeline of the machine equipment, is connected to the connector 1 to complete the docking and installation of the hydraulic hose. By providing the tightening component 3, the adjustable clamp 33... The inner arc-shaped opening 34 and the arc-shaped protrusion 32 work together to create a concave limiting part at the connection between the hydraulic hose and the connector 1. At the same time, the arc-shaped protrusion 32 and the arc-shaped opening 34 separate several small intervals. These small intervals are relatively independent, so that even if a small leak occurs, it will not spread laterally and cause a large-area leak in the hose joint. At the same time, the sealing of the end of the hydraulic hose by the fixing ring 35 and the arc-shaped ring 36 prevents water vapor or other liquids in the external environment from entering the connection between the hydraulic hose and the connector 1, thereby preventing corrosion or leakage of the hydraulic hose and improving the service life and performance of the hose joint.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
