Description

Technical Field

[0001] This utility model relates to the field of hydraulic connector technology, and in particular to an anti-detachment integrated hydraulic connector. Background Technology

[0002] In industrial hydraulic systems, hydraulic joints are key components for connecting pipelines and transmitting hydraulic energy. They enable the sealed transmission of fluid media such as hydraulic oil, and their connection stability directly affects the safe operation and work efficiency of the entire system.

[0003] Traditional hydraulic joints often rely on threaded connections or simple snap-fit ​​structures for fixation. Under long-term high-frequency vibration or pressure fluctuations, the connection is prone to loosening or even falling off. Furthermore, during the installation process, traditional hydraulic joints often lack a precise alignment structure, leading to misalignment between the connecting pipe and the joint body. This not only increases the difficulty of installation and prolongs the assembly time, but may also cause a decrease in sealing performance due to inaccurate alignment, further exacerbating the risk of leakage.

[0004] To address this, an integrated hydraulic joint designed to prevent detachment is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-detachment integrated hydraulic joint, which can solve the problem that existing hydraulic joints mostly rely on threaded connections or simple snap-fit ​​structures for fixation, and are prone to loosening or even falling off under long-term high-frequency vibration or pressure fluctuations. In addition, traditional hydraulic joints often lack a precise alignment structure during installation, resulting in misalignment between the connecting pipe and the joint body. This not only increases the difficulty of installation and prolongs the assembly time, but may also lead to a decrease in sealing performance due to inaccurate alignment, further aggravating the risk of leakage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-detachment integrated hydraulic connector, comprising a connector body, with connecting pipes at both ends of the connector body, an alignment component between the connecting pipes and opposite sides of the connector body, and anti-detachment components at both ends of the surface of the connector body. Each anti-detachment component includes a sliding ring slidably connected to the connecting pipes. Limiting rods penetrate the top and bottom of the sliding ring surface, and a pull ring is fixedly connected to the side of the limiting rod away from the sliding ring. First limiting grooves are formed at the top and bottom of the connecting pipe surface, cooperating with the limiting rods. A fastening tension spring is sleeved at the end of the limiting rod located outside the sliding ring, and both ends of the fastening tension spring are fixedly connected to the sliding ring and the pull ring, respectively.

[0007] Preferably, the alignment component includes alignment blocks, and two alignment blocks are fixedly connected to the top and bottom of both ends of the connector body, respectively.

[0008] Preferably, the end of the connecting pipe near the connector body is provided with an alignment annular groove, which is used in conjunction with the alignment block.

[0009] Preferably, the surface of the alignment block is provided with a second limiting groove, which is used in conjunction with the limiting rod.

[0010] Preferably, guide blocks are fixedly connected to the top and bottom of the surface of the connector body, and a guide groove is provided on the inner wall of the sliding ring, with the guide blocks slidably connected to the surface of the guide groove.

[0011] Preferably, the surface of the guide block is provided with an initial groove, and the limiting rod is used in conjunction with the initial groove.

[0012] Preferably, both ends of the connector body are fixedly connected to positioning tubes, and the surface of the positioning tubes is provided with external threads.

[0013] Preferably, the inner wall of the connecting tube near the positioning tube end is provided with an internal thread, and the internal thread is used in conjunction with the external thread.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application, by setting an anti-detachment component, allows the limiting rod to be engaged in the first limiting groove under the tension of the fastening spring after the connecting pipe is connected to the connector body, forming a mechanical limit. This effectively prevents the connecting pipe from loosening or falling off from the connector body under high-frequency vibration or pressure fluctuation. When disassembly is required, simply pull the pull ring to move the limiting rod away from the first limiting groove, thus separating the connecting pipe from the connector body. The operation is convenient and does not affect the anti-detachment performance for reconnection, solving the problem of easy loosening and falling off of traditional hydraulic connectors that rely on threads or simple snaps.

[0016] 2. By setting up an alignment component, the alignment block can cooperate with the alignment annular groove to quickly determine the relative position of the connecting pipe and the connector body, avoiding docking deviation, thereby achieving accurate and rapid docking of the connecting pipe and the connector body.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] An anti-detachment integrated hydraulic connector includes a connector body 1, with connecting pipes 2 at both ends of the connector body 1. An alignment component 3 is provided between the connecting pipes 2 and the opposite side of the connector body 1. Anti-detachment components 4 are provided at both ends of the surface of the connector body 1. The anti-detachment component 4 includes a sliding ring 401, which is slidably connected to the connecting pipe 2. Limiting rods 402 pass through the top and bottom of the surface of the sliding ring 401. A pull ring 403 is fixedly connected to the side of the limiting rod 402 away from the sliding ring 401. First limiting grooves 5 are provided at the top and bottom of the surface of the connecting pipe 2. The first limiting grooves 5 cooperate with the limiting rod 402. A fastening tension spring 404 is sleeved on the end of the limiting rod 402 located outside the sliding ring 401. The two ends of the fastening tension spring 404 are fixedly connected to the sliding ring 401 and the pull ring 403, respectively.

[0026] In this embodiment: by setting the anti-detachment component 4, the sliding ring 401 can provide a carrier for the limiting rod 402 to pass through and move, and can slide along the surface of the connector body 1. By changing its position, it can cooperate with other components to limit and fix or release the limiting of the connecting tube 2. Under the tension of the fastening spring 404, the limiting rod 402 can be inserted into the first limiting groove 5 of the connecting tube 2 to form a mechanical lock, directly preventing the relative displacement between the connecting tube 2 and the connector body 1, thereby preventing detachment. The pull ring 403 can provide a convenient point of force application for the operator. Pulling the pull ring 403 can move the limiting rod 402, causing it to disengage from the first limiting groove 5, facilitating the disassembly of the connecting tube 2. The operation is simple and effortless. The first limiting groove 5 is opened on the surface of the connecting tube 2 and can precisely cooperate with the limiting rod 402, providing space for the limiting rod 402 to engage and ensuring that the limiting rod 402 can stably limit the connecting tube 2. The fastening tension spring 404 can always apply an inward pulling force to the limiting rod 402, ensuring that the limiting rod 402 can be firmly engaged in the first limiting groove 5 in the non-disassembly state, maintaining the stability of the anti-disengagement effect.

[0027] Specifically, such as Figure 5 As shown, the alignment component 3 includes alignment blocks 301, and the two alignment blocks 301 are fixedly connected to the top and bottom of the two ends of the connector body 1, respectively.

[0028] Specifically, such as Figure 5 As shown, the end of the connecting pipe 2 near the connector body 1 is provided with an alignment annular groove 302, which is used in conjunction with the alignment block 301.

[0029] Specifically, such as Figure 5 As shown, a second limiting groove 303 is provided on the surface of the positioning block 301, and the second limiting groove 303 is used in conjunction with the limiting rod 402.

[0030] In this embodiment: by setting the alignment component 3, when the connecting pipe 2 and the connector body 1 are connected, the alignment block 301 can first be embedded in the alignment annular groove 302 of the connecting pipe 2, which restricts the circumferential rotation of the two from the spatial position, ensuring that the installation angle of the connecting pipe 2 and the connector body 1 is accurate, reducing the adjustment time during installation, and improving the assembly efficiency. The second limiting groove 303 can be used in conjunction with the limiting rod 402. When the connecting pipe 2 and the connector body 1 are aligned and initially fixed, the limiting rod 402 can be driven by the sliding ring 401 to be inserted into the second limiting groove 303, forming a double limiting with the first limiting groove 5, further improving the overall stability and reliability of the anti-detachment component 4.

[0031] Specifically, such as Figure 2 , Figure 4As shown, guide blocks 6 are fixedly connected to the top and bottom of the surface of the connector body 1, and guide grooves 7 are provided on the inner wall of the sliding ring 401. The guide blocks 6 are slidably connected to the surface of the guide grooves 7.

[0032] Specifically, such as Figure 2 As shown, the surface of the guide block 6 is provided with an initial groove 8, and the limiting rod 402 is used in conjunction with the initial groove 8.

[0033] In this embodiment: by setting guide block 6 and guide groove 7, guide block 6 can strictly limit the movement trajectory of sliding ring 401 by cooperating with guide groove 7 on inner wall of sliding ring 401, ensuring that sliding ring 401 can only slide smoothly along the axial direction of connector body 1, avoiding deviation or jamming, and providing a guarantee for the precise insertion of limit rod 402 into limit groove. By setting initial groove 8, in the initial stage of installation of connecting pipe 2 and connector body 1, limit rod 402 can be inserted into initial groove 8, which plays a temporary positioning role for sliding ring 401, preventing sliding ring 401 from moving randomly during installation, making it easier for operators to concentrate on completing the alignment and initial fixation of connecting pipe 2 and connector body 1, and improving the convenience of installation.

[0034] Specifically, such as Figure 3 As shown, both ends of the connector body 1 are fixedly connected to positioning tubes 9, and the surface of the positioning tubes 9 is provided with external threads.

[0035] Specifically, such as Figure 3 As shown, the inner wall of the connecting pipe 2 near the positioning pipe 9 has an internal thread, and the internal thread is used in conjunction with the external thread.

[0036] In this embodiment: Through the above settings, the connecting pipe 2 and the connector body 1 can be tightly connected by the engagement of the external and internal threads, so that the connecting block pipe and the connector body can be initially connected. At the same time, the friction and mechanical locking force between the threads can resist the axial force generated when the hydraulic system is working, reducing the possibility of loosening of the connection. It can also form a double fixation with the anti-detachment component 4, further improving the reliability of the overall connection and avoiding the problem of falling off.

[0037] Working principle: First, align the alignment block 301 and insert it into the alignment annular groove 302. Then, rotate the connecting pipe 2. Through the engagement of its internal thread with the external thread on the surface of the connector body 1, the two connecting pipes 2 can be initially fixed at both ends of the connector body 1. Then, pull the pull ring 403, which drives the limiting rod 402 to move outward, causing the limiting rod 402 to disengage from the initial groove 8 on the surface of the guide block 6. At this time, the fastening spring 404 will be stretched, and then push the sliding ring 401 to slide along the surface of the connector body 1. Using the cooperation of the guide block 6 and the guide groove 7, the sliding ring 401 is slid to the surface of the connecting pipe 2. After releasing the pull ring 403, when the sliding ring 401 slides to the appropriate position, under the tension of the fastening spring 404, the limiting rod 402 will return to its original position inward. This causes the limiting rod 402 to sequentially engage with the second limiting groove 303 on the surface of the alignment block 301 and the first limiting groove 5 on the surface of the connecting pipe 2, forming a double mechanical limit, thus completing the anti-detachment fixation. When it is necessary to disconnect the connecting pipe 2 from the connector body 1, pull the pull ring 403 again to move the limiting rod 402 outward, causing it to disengage from the first limiting groove 5 and the second limiting groove 303. Then push the sliding ring 401 to move away from the connecting pipe 2 until the limiting rod 402 is aligned with the initial groove 8 on the guide block 6. Release the pull ring 403 to allow the limiting rod 402 to engage with the initial groove 8, temporarily fixing the position of the sliding ring 401. Finally, rotate the connecting pipe 2 in the opposite direction to separate the internal thread from the external thread of the positioning pipe 9 until the connecting pipe 2 is completely detached from the positioning pipe 9.

[0038] The above are merely preferred embodiments of the present utility model and are 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.
