Description

Technical Field

[0001] This utility model belongs to the technical field of pipe connection fittings, specifically a rotatable and adjustable compression fitting. Background Technology

[0002] Compression fittings are commonly used components for pipe connections and are widely applied in hydraulic, pneumatic, and fluid transport fields.

[0003] Existing compression fittings typically employ a fixed connection structure, meaning that the fitting body cannot rotate relative to the pipe after connection. When angular deviations occur during pipe installation or when the pipe routing needs to be adjusted later, the entire fitting must be disassembled and reassembled, which is cumbersome and inefficient. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a rotatable adjustable ferrule connector, which effectively solves the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotatable and adjustable ferrule connector, including a first connector, a connecting tube fixedly connected to the lower part of the first connector, a positioning groove distributed in an annular array below the connecting tube, a second connector rotatably connected to the lower part of the connecting tube, an annular groove on one side of the first connector and one side of the second connector, a sealing ring provided inside the two annular grooves, a threaded sleeve fixedly connected to the outside of both the first connector and the second connector, and a limit mechanism provided on the outside of the second connector.

[0006] Preferably, the limiting mechanism includes a first annular plate, which is fixedly sleeved on the outside of the second connector. Support rods are fixedly connected to both sides below the first annular plate, and the same second annular plate is fixedly connected to the bottom of the two support rods. The second annular plate is fixedly sleeved on the outside of the second connector.

[0007] Preferably, a slider is slidably sleeved on the outside of each of the two support rods, a positioning rod is fixedly connected above each of the two sliders, the positioning rod and the positioning groove are adapted to each other, a first spring is fixedly connected below each of the two sliders, the lower part of the two first springs is fixedly connected to the second annular plate, the two first springs are respectively sleeved on the outside of the two support rods, and a limit groove is formed below each of the two sliders.

[0008] Preferably, U-shaped blocks are fixedly connected to both sides of the second annular plate, and crossbars are fixedly connected inside the two U-shaped blocks. Limiting rods are rotatably connected to the outside of the two crossbars, and the limiting rods are adapted to the limiting grooves.

[0009] Preferably, a pressure block is fixedly connected to the lower part of each of the two limiting rods, and a second spring is fixedly connected to one side of each of the two pressure blocks, with one side of the second spring fixedly connected to the second connector.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model allows the sliding blocks on both sides to move downwards, which in turn moves the positioning rod downwards and compresses the first spring. When the positioning rod moves away from the positioning groove on the connecting tube, the connecting tube is rotated to a suitable angle, and the spring force is used to reset the positioning rod, allowing it to insert into the matching positioning groove. This enables multi-angle rotation, requires no tools, and can be unlocked and locked manually. The operation is simple and can be completed by a single person, greatly improving assembly efficiency. It is especially suitable for assembly scenarios with limited space.

[0012] 2. This utility model moves the pressure blocks on both sides closer together by pressing them together. The pressure blocks move the lower part of the limiting rod closer together, while compressing the second spring. The upper part of the limiting rod moves away from the limiting groove on the slider. At this time, the slider can be moved. The limiting rod can limit the slider, which can prevent the device from being accidentally rotated during use and improve the stability of the device.

[0020] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example 1, by Figures 1-4 The present invention includes a first connector 1, with a connecting pipe 2 fixedly connected to the lower part of the first connector 1. A positioning groove 8 arranged in annular array is provided below the connecting pipe 2. A second connector 3 is rotatably connected to the lower part of the connecting pipe 2. The connecting pipe 2 is a hollow pipe used to connect the first connector 1 and the second connector 3. The lower part of the connecting pipe 2 is rotatably connected to the second connector 3, allowing the second connector 3 to rotate flexibly relative to the connecting pipe 2. Annular grooves 5 are provided on one side of the first connector 1 and one side of the second connector 3. A sealing ring 6 is installed inside the two annular grooves 5. The annular grooves 5 provide installation and positioning space for the sealing ring 6, ensuring that the sealing ring 6 will not shift during connection or use. When the first connector 1 is connected to an external pipe, or the second connector 3 is connected to an external pipe, the sealing ring 6 will be squeezed and deformed to fill the connection gap, thereby effectively preventing media leakage from the connection point and significantly improving the sealing performance of the overall structure. Threaded sleeves 4 are fixedly connected to the outside of both the first connector 1 and the second connector 3. A limiting mechanism 7 is provided on the outside of the second connector 3, which is used to adjust the rotation of the connecting pipe 2.

[0022] The limiting mechanism 7 includes a first annular plate 701, which is fixedly sleeved on the outside of the second connector 3. Support rods 703 are fixedly connected to both sides below the first annular plate 701. A second annular plate 702 is fixedly connected below the two support rods 703. The second annular plate 702 is fixedly sleeved on the outside of the second connector 3. The two support rods 703 are both fixedly connected to the same second annular plate 702 below. This design allows the originally dispersed support forces to converge, forming a unified and stable bottom integration platform. Simultaneously, the second annular plate 702 is also fixedly sleeved on the outside of the second connector 3, further strengthening the connection stability with the second connector 3. Sliding blocks 704 are slidably sleeved on the outside of each of the two support rods 703. Positioning rods 705 are fixedly connected above each of the two sliding blocks 704, and the positioning rods 705 are compatible with positioning grooves 8. First springs 711 are fixedly connected below each of the two sliding blocks 704, and the lower parts of the two first springs 711 are fixedly connected to the second annular plate 702. Springs 711 are respectively sleeved on the outside of the two support rods 703. The lower parts of the two first springs 711 are tightly fixedly connected to the second annular plate 702, and are neatly sleeved on the outside of the two support rods 703. In this way, when an external force is applied to the slider 704 and it is displaced, the first springs 711 will generate a reverse elastic force, causing the slider 704 to quickly return to its original position after the external force disappears. Limit grooves 706 are provided on the lower part of both sliders 704. U-shaped blocks 707 are fixedly connected to both sides of the second annular plate 702. Each of the blocks 707 has a crossbar 708 fixedly connected inside. Each of the two crossbars 708 has a limiting rod 709 rotatably connected to its exterior. The limiting rod 709 is adapted to the limiting groove 706. Each of the two limiting rods 709 has a pressure block 710 fixedly connected below it. Each of the two pressure blocks 710 has a second spring 712 fixedly connected to its corresponding side. One side of the second spring 712 is fixedly connected to the second connector 3. The limiting rod 709 can be inserted into the limiting groove 706, thereby effectively limiting the further movement of the slider 704 and playing a reliable limiting role.

[0023] Working principle: In use, the first connector 1 and the second connector 3 are connected to the external pipe through the cooperation of the threaded sleeve 4 and the sealing ring 6. By pressing the pressure blocks 710 on both sides and moving them closer to each other, the pressure blocks 710 drive the lower part of the limiting rod 709 to move closer to each other, while compressing the second spring 712. The upper part of the limiting rod 709 will move away from the limiting groove 706 on the slider 704. At this time, the slider 704 can be moved. By sliding the sliders 704 on both sides downward, the slider 704 drives the positioning rod 705 downward, while compressing the first spring 711. When the positioning rod 705 moves away from the positioning groove 8 on the connecting pipe 2, the connecting pipe 2 is rotated to a suitable angle, and the spring force is used to reset the positioning rod 705, so that the positioning rod 705 is inserted into the matching positioning groove 8.
