Description

Technical Field

[0001] This utility model relates to the field of shaft tube connection technology, and in particular to a shaft tube fixing structure that is easy to assemble and disassemble. Background Technology

[0002] A shaft tube is a mechanical component primarily used to convert between rotary and linear motion or to transmit power. Its core functions include support, transmission, and sealing, with specific applications varying depending on the scenario. Shaft tubes require installation during use, necessitating the use of specialized fixing structures.

[0003] Chinese utility model patent CN217950935U discloses a quick-installation shaft tube fixing structure. This device involves placing a limiting shaft plate into the recessed cavity of a fixing base, embedding it between connecting shaft plates, then inserting the stud at the end of the shaft tube into the alignment shaft hole and the threaded hole of the limiting shaft plate. Finally, by pressing the reset spring plates on both sides of the fixing base, a protective cover box is nested onto the fixing base. Releasing the fixing base allows the shaft tube to rotate between the protective cover box and the fixing shaft base, enabling quick installation and disassembly of the shaft connection structure. This can be applied to shaft connection fixing structures requiring rapid installation and disassembly. Regarding the aforementioned related technology, the inventors believe the following drawbacks exist:

[0004] In practical use, this device lacks an integrated structure for fixing the limiting shaft plate. When the stud on the shaft tube is threaded to the threaded hole on the limiting shaft plate, the limiting shaft plate rotates along with it, making it difficult to connect the shaft tube to the limiting shaft plate smoothly. This affects the installation of the shaft tube. Therefore, we provide a shaft tube fixing structure that is easy to disassemble and assemble. Utility Model Content

[0005] To address the problem of difficulty in smoothly connecting the shaft tube and the limiting shaft plate in the aforementioned background technology, this utility model provides a shaft tube fixing structure that is easy to assemble and disassemble.

[0006] This utility model is achieved by the following technical solution: a shaft tube fixing structure that is easy to assemble and disassemble, including a fixing socket and a fixing component. The fixing socket has a slot, a fixing block is inserted into the slot, a placement groove is opened on the fixing block, a ring is set inside the placement groove, and insertion holes are opened on the fixing socket and the fixing block at positions corresponding to the holes of the ring. The shaft tube body is provided on one side of the fixing socket.

[0007] The fixing component includes a lead screw rotatably connected inside the fixing block via an H-shaped bracket, with the end of the lead screw extending to the outside of the fixing block and threadedly connected to it. A threaded block is threadedly connected to the outside of the lead screw. Two sets of locking blocks are symmetrically arranged inside the fixing block. A connecting rod is hinged between the locking blocks and the threaded blocks via a hinge. A fixing frame is symmetrically fixedly connected to the locking blocks. A connecting block is symmetrically fixedly connected to the ring. A fixing groove is provided on the connecting block.

[0008] As a further improvement to the above solution, the fixed socket has a corresponding slot for the corresponding card block.

[0009] As a further improvement to the above solution, the inner surface of the ring is provided with an internal thread, and the lower outer side of the shaft tube body is provided with an external thread that is compatible with the internal thread.

[0010] As a further improvement to the above solution, the fixed insert has two sets of guide rods symmetrically fixedly connected inside, and the card block has two sets of guide blocks symmetrically fixedly connected, with the guide blocks slidingly connected to the guide rods on the same side.

[0011] As a further improvement to the above solution, the diameter of the insertion hole is larger than the diameter of the hole on the ring.

[0012] As a further improvement to the above solution, the diameter of the insertion hole is larger than the diameter of the shaft tube body.

[0013] As a further improvement to the above solution, the longitudinal section of the fixing groove has a convex shape structure that rotates 90° clockwise.

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

[0015] 1. This utility model uses a rotating lead screw to drive the threaded block to move. Utilizing the sliding connection between the guide block and the guide rod, and the hinged connection between the threaded block, the locking block, and the connecting rod, two sets of locking blocks can be pushed to move simultaneously in opposite directions. When the locking block moves into the slot, it can fix the fixing block onto the fixing socket. Simultaneously, the movement of the locking block also drives two sets of fixing brackets to move together. When the locking block moves into the slot, the fixing bracket engages with the fixing slot, facilitating simultaneous fixing of the ring. This prevents the ring from rotating during the connection of the shaft tube body, thus avoiding interference with installation. It is highly practical.

[0016] 2. This utility model facilitates the removal of the fixed plug from the fixed socket by reversing the lead screw, and at this time the ring is in an unfixed state, which makes it easy to replace the ring with a different hole size to fit the shaft tube with a different diameter, thereby improving the applicability of the device.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] Example 1:

[0024] Please combine Figure 1-3 This embodiment provides a shaft tube fixing structure that is easy to assemble and disassemble, including a fixing socket 1. The fixing socket 1 has a slot, and a fixing block 2 is inserted into the slot. The fixing block 2 has a placement groove, and a ring 3 is provided inside the placement groove. The fixing socket 1 and the fixing block 2 have insertion holes at positions corresponding to the holes in the ring 3. A shaft tube body 4 is provided on one side of the fixing socket 1. The diameter of the insertion hole is larger than the diameter of the hole on the ring 3, and the diameter of the insertion hole is larger than the diameter of the shaft tube body 4.

[0025] A fixing assembly for fixing the fixing block 2 and the ring 3 includes a lead screw 101 rotatably connected inside the fixing block 2 via an H-shaped bracket, with the end of the lead screw 101 extending to the outside of the fixing block 2 and threadedly connected to it. A threaded block 102 is threadedly connected to the outside of the lead screw 101. Two sets of locking blocks 103 are symmetrically arranged inside the fixing block 2. A connecting rod 104 is hinged between the locking blocks 103 and the threaded blocks 102 via a hinge. Fixing brackets 105 are symmetrically fixedly connected to the locking blocks 103. The ring 3... A connecting block 106 is symmetrically fixedly connected to the upper part, and a fixing groove 107 is provided on the connecting block 106. A corresponding slot 5 is provided on the fixed socket 1 at the position of the corresponding card block 103. Two sets of guide rods 108 are symmetrically fixedly connected inside the fixed plug 2. Two sets of guide blocks 109 are symmetrically fixedly connected on the card block 103, and the guide blocks 109 are slidably connected to the guide rods 108 on the same side, which can play a certain guiding role in the stable movement of the card block 103. The longitudinal section of the fixing groove 107 is a convex structure that rotates 90° clockwise.

[0026] The implementation principle of the easy-to-disassemble shaft tube fixing structure in this application embodiment is as follows: First, place the ring 3 in the placement groove and make the fixing groove 107 on the connecting block 106 face the inner side. When the ring 3 is completely placed in the placement groove, the fixing bracket 105 can also enter the fixing groove 107 on the connecting block 106 on the same side. Then, rotate the screw 101. By rotating the screw 101, the threaded block 102 is moved. Utilizing the sliding connection between the guide block 109 and the guide rod 108, and the hinged connection between the threaded block 102 and the locking block 103 and the connecting rod 104, the two sets of locking blocks 103 can be pushed to move in opposite directions simultaneously. When the locking block 103... When the device moves into the slot 5, it can fix the fixing block 2 onto the fixing socket 1. At the same time, the movement of the locking block 103 can also drive the two sets of fixing brackets 105 to move together. When the locking block 103 moves into the slot 5, the fixing bracket 105 is engaged with the fixing groove 107, which makes it easy to fix the ring 3 at the same time. Finally, the shaft tube body 4 can be connected to the ring 3. The fixing block 2 can be pulled out from the fixing socket 1 by reversing the screw 101. At this time, the ring 3 is in an unfixed state, which makes it easy to replace the ring 3 with different hole sizes to fit the shaft tube body 4 with different diameters, effectively improving the applicability of the device.

[0027] Example 2:

[0028] Based on Embodiment 1, this embodiment is further improved in that: the inner side of the ring 3 is provided with an internal thread, and the lower outer side of the shaft tube body 4 is provided with an external thread, and the external thread is compatible with the internal thread, so as to facilitate the connection between the shaft tube body 4 and the ring 3.
