Description

Technical Field

[0001] The utility model relates to the technical field of rubber hoses, in particular to a high-pressure flexible rubber hose assembly. Background Art

[0002] High-pressure flexible rubber hose, also often called high-pressure rubber hose or high-pressure elastic hose, is a pipe designed for transmitting fluids (such as water, gas, oil, etc.) and capable of maintaining good sealing and flexibility under high-pressure environments. This type of hose is widely used in many industrial fields, including petrochemicals, mining, construction, shipbuilding, agricultural irrigation, hydraulic equipment, etc., and is favored for its unique performance and advantages.

[0003] Although the existing high-pressure flexible rubber hose has high-pressure bearing capacity and good flexibility, in actual applications, due to the fixed joints at both ends, it is difficult to adjust the angle once connected, especially in working scenarios where space is limited or frequent changes in direction are required. This not only affects work efficiency, but may also cause damage to the hose due to excessive twisting, posing a safety hazard. Utility Model Content

[0004] The utility model aims to provide a high-pressure flexible rubber hose assembly to solve the problems of inconvenience in installation and insufficient flexibility in use caused by fixed angle restrictions after the high-pressure flexible rubber hose is connected as mentioned in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-pressure flexible rubber hose assembly, comprising a rubber hose body, the connecting ends of the rubber hose body are jointly sleeved with a connecting sleeve, a rotatable limiting ring is symmetrically provided inside the middle of the connecting sleeve, and a card interface that matches the connecting end of the rubber hose body is provided on the limiting ring, the connecting end of the rubber hose body extends into the card interface and is fixedly sleeved with an elastic clamping ring, an annular card groove that matches the elastic clamping ring structure is provided on the inner wall of the card interface, and positioning screws are symmetrically provided at the upper and lower ends of the connecting sleeve, and a plurality of positioning screw holes that match the positioning screw structure are evenly surrounded on the side away from the limiting ring.

[0006] Preferably, arc-shaped sliders are provided on both sides of the limiting ring, and an annular sliding groove matching the arc-shaped slider structure is symmetrically provided on the inner wall in the middle of the connecting sleeve.

[0007] Preferably, both inner walls at the upper and lower ends of the connecting sleeve are provided with limiting sleeves, and one end of the positioning screw pin located inside the connecting sleeve is movably inserted into the limiting sleeve.

[0008] Preferably, both upper and lower ends of the connecting sleeve are provided with through holes, and sealing rings are provided on the inner walls of the through holes at both upper and lower ends of the connecting sleeve.

[0009] Preferably, reinforcement pieces are symmetrically provided on the outside of the perforations at the upper and lower ends of the connecting sleeve, and the reinforcement pieces are all arc-shaped structures and rubber pads are bonded and fixed on the inner walls.

[0010] Preferably, both ends of each group of the reinforcement members are interspersed with a fixed shaft, and both ends of the fixed shaft are sleeved with springs on the outside.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the high-pressure flexible rubber hose assembly can easily adjust the hose connection angle according to actual needs, greatly improving the convenience of installation and the flexibility of use, and is particularly suitable for working environments with narrow space or complex layouts. The high-pressure flexible rubber hose assembly realizes flexible angle adjustment of the connection end by combining a rotatable limit ring with a connecting sleeve at both ends of the rubber hose body. When the end of the hose body is inserted into the card interface in the connecting sleeve, the sealing connection is achieved by relying on the tightening effect of the elastic clamp ring in the annular card groove. The limit ring can rotate freely within a preset angle range. After positioning as required, the hose direction is fixed by the cooperation of the positioning screw pin and the screw hole.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3The utility model provides a technical solution: a high-pressure flexible rubber hose assembly, including a rubber hose body 1, the connecting end of the rubber hose body 1 is jointly sleeved with a connecting sleeve 2, a rotatable limiting ring 3 is symmetrically provided inside the middle of the connecting sleeve 2, and a card interface 4 that matches the connecting end of the rubber hose body 1 is provided on the limiting ring 3, the connecting end of the rubber hose body 1 extends into the card interface 4 and is fixedly sleeved with an elastic clamping ring 5, an annular card groove 12 that matches the structure of the elastic clamping ring 5 is provided on the inner wall of the card interface 4, the annular card groove 12 is precisely matched with the elastic clamping ring 5 to ensure the sealing and stability of the connection, and can effectively prevent leakage even under high pressure, and both sides of the upper and lower ends of the connecting sleeve 2 are rotatably connected with positioning screws 8 through a threaded structure, The inner end of the positioning screw 8 extends to the inside of the connecting sleeve 2, and a plurality of positioning screw holes 11 that match the positioning screw 8 structure are evenly arranged around the side away from the limiting ring 3. The connecting ends of the two rubber hose bodies 1 of this structure can be inserted into the upper and lower ends of the connecting sleeve 2 when connected to each other, and the card interface 4 provided on the limiting ring 3 can be inserted in conjunction with the connecting end of the rubber hose body 1 until the elastic clamping ring 5 is squeezed into the annular card groove 12 to achieve a fastened connection. At this time, the limiting ring 3 can rotate freely within a certain range to adjust the direction of the rubber hose body 1 according to actual needs, and at the same time, the positioning screw 8 is used to pass through the selected positioning screw hole 11 for fixing, so as to stabilize the rubber hose body 1 at any desired angle to avoid the hose twisting during operation. The invention can solve the problem of angle adjustment of traditional high-pressure flexible rubber hose in complex working environment, which not only greatly improves the flexibility and efficiency of operation, but also significantly enhances the safety and durability of hose use. Arc-shaped sliders 9 are arranged on both sides of the limit ring 3, and an annular slide groove matched with the structure of the arc-shaped slider 9 is symmetrically arranged on the inner wall in the middle of the connecting sleeve 2. The limit ring 3 of this structure can slide in the annular slide groove on the inner wall of the connecting sleeve 2 through the arc-shaped slider 9, which can not only ensure that the limit ring 3 is stable and smooth when rotating to adjust the angle without sticking, but also provide additional radial support force for the rubber hose body 1 through the close cooperation between the arc-shaped slider 9 and the annular slide groove after rotating into place, so as to prevent accidental displacement due to external force. The stability and reliability of the connection are further enhanced. The inner walls of both sides of the upper and lower ends of the connecting sleeve 2 are welded and fixed with limit sleeves 7, and one end of the positioning screw pin 8 located inside the connecting sleeve 2 is movably inserted into the inside of the limit sleeve 7. The positioning screw pin 8 of this structure will pass through the limit sleeve 7 during the rotation activity, so that the limit sleeve 7 can ensure the accurate positioning of the positioning screw pin 8, avoid the positioning screw pin 8 from being misplaced or misplaced, thereby realizing the reliable fixation of the angle of the rubber hose body 1. The upper and lower ends of the connecting sleeve 2 are provided with perforations, and the inner walls of the perforations at the upper and lower ends of the connecting sleeve 2 are provided with sealing rings 6. The sealing ring 6 of this structure serves as a key sealing element to insert the rubber hose body 1 into the perforation of the connecting sleeve 2 and fit closely therewith, forming a barrier to prevent fluid leakage.The sealing ring 6 can adapt to high-pressure environments and effectively prevent the leakage of media (such as water, gas, oil, etc.) from the connection, ensuring the sealing performance and safety of the entire hose assembly during the transmission process. The outer parts of the perforations at the upper and lower ends of the connecting sleeve 2 are symmetrically provided with reinforcement pieces 10, which are movably connected to the outer wall of the port of the connecting sleeve 2. The reinforcement pieces 10 are all arc-shaped structures and rubber pads are bonded and fixed on the inner wall. The two ends of each group of reinforcement pieces 10 are interspersed with a fixed shaft 13, and the outer parts of the two ends of the fixed shaft 13 are sleeved with springs. Each group of reinforcement pieces 10 of this structure can be closed or separated at the upper and lower ends of the connecting sleeve 2 through the cooperation of the fixed shaft 13 and the spring, so as to be clamped and fixed at the connection between the rubber hose body 1 and the port of the connecting sleeve 2, thereby further enhancing the sealing effect and further blocking the influence of the external environment on the internal fluid transmission. It not only significantly enhances the impact resistance and sealing performance of the port of the connecting sleeve 2, but also ensures the flexibility and stability of the hose assembly under high-pressure working conditions.

[0018] Working principle: When using the high-pressure flexible rubber hose assembly, first slowly insert the connecting ends of the two rubber hose bodies 1 into the interior of the connecting sleeve 2 and contact the limiting ring 3 until they are aligned with the card interface 4 and the elastic clamping ring 5 is pushed into the annular card groove 12 to achieve the initial tightening of the two rubber hose bodies 1. Then, the rubber hose body 1 is used to drive the limiting ring 3 to rotate and adjust. When the limiting ring 3 rotates, it will drive the arc-shaped slider 9 to slide in the annular groove on the inner wall of the connecting sleeve 2 until the limiting ring 3 is freely rotated to a suitable angle according to the actual installation requirements. Then, the positioning screw 8 is threaded. The structure rotates on the connecting sleeve 2, and the positioning screw 8 can be fixed in the corresponding positioning screw hole 11 under the limit of the limit sleeve 7 when it rotates, and then the sealing ring 6 is glued and fixed to the perforated inner walls at the upper and lower ends of the connecting sleeve 2 to ensure that the sealing ring 6 can fit tightly when the rubber hose body 1 is inserted. Finally, the two ends of the reinforcement 10 are inserted through the fixed shaft 13 and assembled to the corresponding positions of the connecting sleeve 2, and the reinforcement 10 can automatically adapt to and fit tightly to the connection area between the rubber hose body 1 and the connecting sleeve 2 under the action of the spring, further improving the sealing and stability, thereby completing a series of tasks.
