Description

Technical Field

[0001] This invention relates to the field of hydraulic equipment accessories technology, specifically a hydraulic hose assembly with a clamping connection structure. Background Technology

[0002] Hydraulics is a term used in the machinery and electromechanical industries. Hydraulics can be used as a power transmission method or as a hydraulic control method. Hydraulic transmission uses liquid as the working fluid and transmits power through the pressure of liquids such as hydraulic oil. A complete hydraulic system consists of five parts: energy device, actuator, control and regulation device, auxiliary device, and liquid medium. Usually, the transmission of hydraulic medium requires the use of hydraulic hose assemblies to transport hydraulic oil and other liquid media.

[0003] However, existing hydraulic hose assemblies still have some problems in use:

[0004] An existing hydraulic hose assembly, such as the one described in Chinese Patent Publication No. CN206889925U, includes a connecting hose with connecting connectors crimped at both ends. Each connecting connector sequentially includes a connecting end, a seamless tube, and a connecting tail core. The seamless tube has a connecting end and a connecting tail core fixedly installed at both ends. The connecting tail core includes a core body, a crimping sleeve, and an annular crimping groove with an open end formed between the core body and the crimping sleeve. However, existing hydraulic hose assemblies typically connect to hydraulic equipment only via nuts. Hydraulic equipment often undergoes mechanical movement and vibration. The existing structure is too simple, and without timely maintenance after prolonged use, the threaded connection may loosen, easily leading to leaks. This affects the normal operation of the hydraulic equipment, and hydraulic oil leaks can cause economic losses and pollution to the workshop or the external environment. Furthermore, existing hydraulic hose assemblies typically have the hose fixedly connected to the connecting structure and cannot be disassembled. When the hydraulic hose ages or breaks, the entire hydraulic hose assembly needs to be replaced, undoubtedly increasing the cost. If the hydraulic hose is used in braking equipment and leaks occur, it will create a significant safety hazard.

[0005] To address the aforementioned issues, an innovative design was implemented based on the existing hydraulic hose assembly with a clamping connection structure. Summary of the Invention

[0006] The purpose of this invention is to provide a hydraulic hose assembly with a clamping connection structure to solve the problem mentioned in the background art that the existing hydraulic hose assemblies are fixed by the suggested threaded connection method, which can loosen due to vibration and other factors after long-term use, easily causing oil leakage, polluting the external environment, causing economic losses, and leading to equipment downtime or abnormal operation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic hose assembly with a clamping connection structure, comprising a connecting component, a hose body, and a connecting guide tube:

[0008] The right end of the connecting component is provided with a flexible hose body, and the left end of the connecting component is provided with a connecting conduit.

[0009] A connector is fixedly installed at the right end of the connecting pipe, and a sealing ring is installed at the right end of the connector.

[0010] The left end of the connecting component is fitted with a first sleeve, and the inner wall of the left end of the first sleeve is threadedly connected to the right end of the connector.

[0011] An inner wall sleeve is fixedly installed on the inner wall of the right end of the connecting component, and an anti-slip ring is fixedly installed on the outer wall of the inner wall sleeve. The outer wall of the inner wall sleeve and the anti-slip ring are in contact with the inner wall of the hose body.

[0012] The connecting component has a fixing groove on the outer wall of the right end, and a clamping claw is engaged inside the fixing groove. A fixing bolt passes through the outer end of the clamping claw, and the fixing bolt is threadedly connected to the fixing groove.

[0013] The right end of the connecting assembly is threaded with a second sleeve, and the inner wall of the right end of the second sleeve contacts the outer wall of the clamping jaw.

[0014] Preferably, the right end of the connector penetrates the interior of the connecting component, and a limiting groove is formed inside the connecting component. Limiting blocks are distributed in a ring array on the outer wall of the right end of the connector, and the limiting blocks and the limiting groove are engaged to form a limiting structure.

[0015] A positioning ring is fixedly connected to the outer left wall of the connecting component, and a positioning groove is provided on the inner wall of the first sleeve. The positioning groove and the positioning ring are engaged to form a limiting structure.

[0016] By adopting the above technical solution, the position between the first sleeve and the connecting component is limited by the positioning ring. When the first sleeve is rotated and threadedly connected to the connector, the rotation between the connecting component and the connector can be limited by the cooperation of the limiting block and the limiting groove.

[0017] Preferably, the clamping claws are arranged in a ring array around the center point of the connecting component, and the inner end of the clamping claws contacts the outer wall of the hose body. The inner wall of the right end of the second sleeve is designed with a slope, and the thickness of the right wall of the second sleeve is less than the thickness of the left wall.

[0018] By adopting the above technical solution, the second sleeve is rotated to move to the right and continuously presses the clamping claw, so that it cooperates with the inner sleeve to clamp the hose body, ensuring a seal. The clamping claw is fixed separately and can be replaced individually if damaged, which is convenient to use and reduces maintenance costs.

[0019] Preferably, the outer wall of the connecting component is provided with a first annular groove, and the first annular groove is provided with a positioning block arranged in an annular array inside the first annular groove. There are two sets of the first annular groove, and the first annular groove is provided on the left and right sides of the connecting component.

[0020] By adopting the above technical solution, two sets of first annular grooves and positioning blocks are set up to engage with the first positioning plate and the second positioning plate respectively, thereby restricting the rotation of the first sleeve and the movable ring.

[0021] Preferably, a first mounting groove is provided on the right side of the first sleeve, and a first positioning plate passes through the first mounting groove. The inner end of the first positioning plate is designed with a bevel, and the right side of the first positioning plate passes through the first annular groove and engages with the positioning block.

[0022] A first connecting plate is fixedly installed on the left side of the first positioning plate, and a first spring is fixed on the outer side of the first connecting plate, and the outer side of the first spring is fixedly connected to the inner wall of the first mounting groove.

[0023] By adopting the above technical solution, the first positioning plate is pushed into the first annular groove by the first spring and engaged with the positioning block, which can restrict the rotation of the first sleeve, thereby preventing the connection with the connector from becoming loose and improving the reliability and sealing of the connection with the connecting pipe.

[0024] Preferably, the connecting component has a second annular groove in the middle, and a sliding ring is sleeved inside the second annular groove. A sliding guide rod is connected inside the second annular groove, and the sliding guide rod passes through the sliding ring.

[0025] A strong spring passes through the left end of the sliding guide rod, and the right end of the strong spring is fixedly connected to the left side of the sliding ring.

[0026] By adopting the above technical solution and setting multiple sets of strong springs, the sliding ring can be pushed to keep it on the right side of the second annular groove.

[0027] Preferably, the sliding ring is connected to an adjusting ring on the outer bearing, and a limiting ring is fixed to the left end of the adjusting ring. A square groove is provided on the right side of the first positioning plate. The left outer wall of the limiting ring is designed with an inclined surface, and the left end of the limiting ring penetrates the interior of the first mounting groove and contacts the outer end face of the square groove.

[0028] The inner wall of the limiting ring is provided with a first toothed groove, and the inner wall of the first mounting groove is connected to a first toothed ring, and the first toothed groove and the first toothed ring are engaged.

[0029] By adopting the above technical solution, the engagement of the first tooth groove with the first tooth ring enables the rotation of the adjusting ring to drive the first sleeve to rotate synchronously, while the limiting ring can push the first positioning plate to move outward to release the engagement with the positioning block, thereby releasing the restriction on the rotation of the first sleeve.

[0030] Preferably, the right end bearing of the connecting assembly is connected to a movable ring, and the right end of the movable ring is fixedly connected to a limit rod, and the right end of the limit rod passes through the inside of the second sleeve to form a sliding limit structure.

[0031] By adopting the above technical solution, the setting of the limiting rod enables the rotation of the movable ring to drive the second sleeve to rotate synchronously, and the left and right movement of the second sleeve is not restricted.

[0032] Preferably, a second mounting groove is provided on the left side of the movable ring, and a second positioning plate is provided inside the second mounting groove. The inner end of the second positioning plate extends through the movable ring into the first annular groove, and the inner end of the second positioning plate is engaged with the positioning block.

[0033] A limiting post is fixed on the right side of the second mounting groove, and a second connecting plate is fixed on the right side of the second positioning plate. The limiting post passes through the second connecting plate, and a second spring passes through the lower end of the limiting post. The outer end of the second spring is fixedly connected to the second connecting plate.

[0034] By adopting the above technical solution, the second positioning plate is pushed outward by the second spring, which can release its engagement with the positioning block and thus release the restriction on the rotation of the moving ring.

[0035] Preferably, the outer wall of the left end of the movable ring is connected to a second toothed ring, the right end of the adjusting ring is provided with a locking groove, and the outer wall of the locking groove is provided with a second toothed groove, and the second toothed groove is engaged with the second toothed ring.

[0036] The inner wall of the right end of the movable ring is designed with a slope, and the inner wall of the right end of the movable ring is in contact with the outer end of the second positioning plate.

[0037] Using the above technical solution, when the second tooth groove meshes with the second tooth ring and the inner wall of the right end of the adjusting ring does not contact the second positioning plate, the rotation of the adjusting ring can drive the movable ring to rotate synchronously. At the same time, when the adjusting ring is at the rightmost end of the second annular groove, the adjusting ring presses the second positioning plate and the positioning block to engage, which can limit the rotation of the movable ring and ensure reliable clamping of the hose body by the clamping claw.

[0038] Compared with the prior art, the beneficial effects of the present invention are as follows: the hydraulic hose assembly with the clamping connection structure can reliably connect the hose body while facilitating hose replacement by setting the clamping clamping structure between the hose body and the connecting component, without the need to replace the entire hose assembly, thus reducing the cost of use and maintenance. In addition, the hydraulic hose assembly is equipped with a limit mechanism, which can effectively limit the loosening of the clamping structure and the threaded connection mechanism, ensuring the reliability of the hydraulic hose connection and the safe operation of the hydraulic equipment.

[0039] 1. By setting up a clamping structure, the hose and connecting components can be disassembled while ensuring reliable sealing. Compared with traditional integrated hydraulic hose assemblies, the hose can be disassembled and replaced separately when it ages or is damaged, reducing the cost of use and maintenance. The setting of a limit structure can prevent the clamping structure from loosening and leaking, ensuring stable oil pressure in the hydraulic equipment and ensuring stable operation of the hydraulic equipment. In addition, the clamping jaw adopts a split design, and when a single clamping jaw is damaged, it can be replaced separately, reducing costs and improving ease of operation.

[0040] 2. By setting a limiting structure, the connecting components at both ends can be limited simultaneously. The installation and disassembly of the hose body and connector can be achieved by adjusting the position of the adjusting ring used for limiting, making it more convenient to use. Compared with traditional clamps or simple threaded connections, it has stronger stability and reliability. Since hydraulic oil flows inside the hydraulic hose, the limiting structure set in this hydraulic hose can prevent the connection structure from loosening due to vibration and other factors, preventing the risk of oil leakage or interface detachment. It ensures the stable operation of hydraulic equipment and also prevents the financial cost and environmental pollution caused by hydraulic oil leakage. If this hydraulic hose is used in braking equipment, it can provide a high level of safety. Attached Figure Description

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Please see Figure 1-12 The present invention provides a technical solution: a hydraulic hose assembly with a clamping connection structure, including a connecting component 1, a hose body 2, and a connecting guide tube 3. The hose body 2 is provided at the right end of the connecting component 1, and the connecting guide tube 3 is provided at the left end of the connecting component 1. A connector 4 is fixedly installed at the right end of the connecting guide tube 3, and a sealing ring 5 is installed at the right end of the connector 4. By rotating the first sleeve 8, its inner wall is threadedly connected to the connector 4, thereby connecting the connector 4 and the connecting guide tube 3. The connecting guide tube 3 is usually located at the equipment end.

[0056] A first sleeve 8 is fitted onto the left end of the connecting component 1, and the inner wall of the left end of the first sleeve 8 is threadedly connected to the right end of the connector 4; an inner wall sleeve 9 is fixedly installed on the inner wall of the right end of the connecting component 1, and an anti-slip ring 10 is fixedly installed on the outer wall of the inner wall sleeve 9, with the outer wall of the inner wall sleeve 9 and the anti-slip ring 10 in contact with the inner wall of the hose body 2; a fixing groove 11 is formed on the outer wall of the right end of the connecting component 1, and a clamping claw 12 is engaged inside the fixing groove 11, with a fixing bolt 13 penetrating through the outer end of the clamping claw 12, and the fixing bolt 13 is threadedly connected to the fixing groove 11; a second sleeve 14 is threadedly connected to the right end of the connecting component 1, and the second sleeve 14... 4. The inner wall of the right end contacts the outer wall of the clamping claw 12; the clamping claw 12 is arranged in a ring array with the center point of the connecting component 1 as the axis, and the inner end of the clamping claw 12 contacts the outer wall of the hose body 2. The inner wall of the right end of the second sleeve 14 is designed with a slope, and the thickness of the right side wall of the second sleeve 14 is less than the thickness of the left side wall. When the second sleeve 14 rotates, it moves to the right and presses the multiple sets of clamping claws 12, so that it clamps, fixes and seals the hose body 2 sleeved outside the inner wall sleeve 9. When it is detachable, the hydraulic hose assembly can be replaced separately after the hose body 2 ages or is damaged, reducing maintenance and use costs.

[0057] The right end of the connector 4 penetrates the interior of the connecting component 1, and a limiting groove 6 is formed inside the connecting component 1. Limiting blocks 7 are distributed in a ring array on the outer wall of the right end of the connector 4, and the limiting blocks 7 are engaged with the limiting groove 6 to form a limiting structure. A positioning ring 40 is fixedly connected to the outer wall of the left side of the connecting component 1. A positioning groove 41 is formed on the inner wall of the first sleeve 8, and the positioning groove 41 is engaged with the positioning ring 40 to form a limiting structure. By cooperating with the positioning ring 40 and the positioning groove 41, the position of the connecting component 1 between the first sleeve 8 is restricted from changing. Rotating the first sleeve 8 causes the connector 4 to move continuously towards the left end of the connecting component 1 for connection. A limiting block 7 is set on the outer wall of the connector 4, which engages with the limiting groove 6 formed on the inner wall of the connecting component 1 to restrict the rotation between the connecting component 1 and the connector 4.

[0058] The outer wall of the connecting component 1 has a first annular groove 15, and positioning blocks 16 are arranged in a circular array inside the first annular groove 15. There are two sets of the first annular groove 15, and the first annular groove 15 is located on the left and right sides of the connecting component 1. The right side of the first sleeve 8 has a first mounting groove 17, and a first positioning plate 18 passes through the first mounting groove 17. The inner end of the first positioning plate 18 is designed with a bevel, and the right side of the first positioning plate 18 passes through the first annular groove 15 and engages with the positioning blocks 16. A first connecting plate 19 is fixedly installed on the left side of the first positioning plate 18. Furthermore, a first spring 20 is fixed to the outer end of the first connecting plate 19, and the outer end of the first spring 20 is fixedly connected to the inner wall of the first mounting groove 17. Through the setting of the first spring 20, the first positioning plate 18 can be pushed to extend into the first annular groove 15 and engage with the positioning block 16, thereby restricting the first sleeve 8 from rotating outside the connecting assembly 1. Since the angle between the connecting assembly 1 and the connector 4 cannot change, it can prevent the first sleeve 8 and the connector 4 from loosening due to vibration and other reasons, thereby improving the reliability of the connection with the equipment.

[0059] A second annular groove 21 is provided in the middle of the connecting component 1, and a sliding ring 22 is fitted inside the second annular groove 21. A sliding guide rod 23 is connected inside the second annular groove 21 and passes through the sliding ring 22. A strong spring 24 passes through the left end of the sliding guide rod 23, and the right end of the strong spring 24 is fixedly connected to the left side of the sliding ring 22. An adjusting ring 25 is connected to the outer bearing of the sliding ring 22, and a limit ring 26 is fixed to the left end of the adjusting ring 25. A square groove 27 is provided on the right side of the first positioning plate 18. The outer wall of the left side of the limit ring 26 is designed with a slope, and the left end of the limit ring 26 passes through the interior of the first mounting groove 17 and contacts the outer end face of the square groove 27. The inner wall of the first mounting groove 17 is provided with a first toothed groove 28, and the inner wall of the first mounting groove 17 is connected to a first toothed ring 29, and the first toothed groove 28 and the first toothed ring 29 are engaged. The strong spring 24 can push the sliding ring 22 and the adjusting ring 25 to the right side of the second annular groove 21. When the adjusting ring 25 is pushed to the left, its left end limiting ring 26 moves into the first mounting groove 17, and pushes the first positioning plate 18 to move and release the engagement with the positioning block 16, thereby releasing the rotation restriction of the first sleeve 8. At the same time, because the first toothed groove 28 and the first toothed ring 29 are engaged, rotating the adjusting ring 25 can drive the first sleeve 8 to rotate synchronously, thereby adjusting the connection state of the connector 4.

[0060] The right end of the connecting assembly 1 is connected to a bearing with a movable ring 30, and a limit rod 31 is fixedly connected to the right end of the movable ring 30. The right end of the limit rod 31 passes through the inside of the second sleeve 14 to form a sliding limit structure. A second mounting groove 32 is provided on the left side of the movable ring 30, and a second positioning plate 33 is provided inside the second mounting groove 32. The inner end of the second positioning plate 33 passes through the movable ring 30 and extends into the first annular groove 15. The inner end of the second positioning plate 33 is engaged with the positioning block 16. A limit post 34 is fixed on the right side of the second mounting groove 32. A second connecting plate 35 is fixed on the right side of the second positioning plate 33. The limit post 34 passes through the second connecting plate 35. A second spring 36 passes through the lower end of the limit post 34, and the outer end of the second spring 36 is fixedly connected to the second connecting plate 35. A second toothed ring 37 is connected to the outer wall of the left end of the movable ring 30. A locking groove 38 is provided on the right end of the adjusting ring 25, and a second toothed groove 39 is provided on the outer wall of the locking groove 38. The second toothed ring 37 is engaged, and the inner wall of the right end of the movable ring 30 is designed with a bevel, and the inner wall of the right end of the movable ring 30 contacts the outer end of the second positioning plate 33. The limiting rod 31 connected to the right end of the movable ring 30 allows it to rotate synchronously with the second sleeve 14 without restricting the horizontal movement of the second sleeve 14. Since the sliding ring 22 and the adjusting ring 25 are located on the right side of the second annular groove 21, the adjusting ring 25 can maintain pressure on the second positioning plate 33 to ensure that the second positioning plate 33 is engaged with the positioning block 16, and restrict the rotation of the movable ring 30 and the second sleeve 14. When the adjusting ring 25 moves to the left to release the pressure on the second positioning plate 33, the second spring 36 pushes the second positioning plate 33 to release the engagement with the positioning block 16. At this time, the second toothed groove 39 and the second toothed ring 37 are still engaged. Rotating the adjusting ring 25 drives the movable ring 30 and the second sleeve 14 to rotate synchronously, thereby adjusting the tightness of the clamping claw 12 on the hose body 2.

[0061] The contents not described in detail in this specification are prior art known to those skilled in the art. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
