Description

Technical Field

[0001] This utility model relates to the field of locking technology, specifically a linkage T-shaped locking device. Background Technology

[0002] Locking devices are mechanical devices used to fix or restrict the movement of objects. They prevent objects from loosening or moving by applying pressure or friction. According to their working principle, they include: mechanical locking devices, hydraulic locking devices, and electromagnetic locking devices. T-type locking blocks are devices used to fix and position mechanical parts. They are usually used in conjunction with a base. Most existing T-type locks are integrated designs. When they are worn or broken, the whole unit needs to be replaced, which affects the convenience of replacement and the locking effect.

[0003] According to the description of a T-shaped locking block published on the patent website (authorization announcement number: CN221503669U), the T-shaped locking block includes "a first locking block, a second locking block, a first mounting hole", etc., to achieve the locking operation.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This T-shaped locking block utilizes a first locking block, a second locking block, and a first mounting hole to achieve locking. During use, the locking operation is achieved through the action of the first and second locking blocks. Since the first and second locking blocks are integrated, if any part of the integrated locking block is damaged, it is usually impossible to replace the damaged part individually; the entire block must be replaced. This results in high repair costs and time consumption, affecting the effectiveness of the product. Therefore, improvements to this locking block are necessary. Utility Model Content

[0007] To achieve the above objectives, the present invention provides the following technical solution: a linkage T-shaped locking device, including a limiting ring, a locking mechanism being provided at the bottom of the limiting ring, and a limiting mechanism being provided at the front side of the locking mechanism;

[0008] The locking mechanism includes a connecting block, which is disposed at the bottom of the limiting ring. A fixing block is fixedly connected to the bottom of the connecting block. A locking block is inserted into the periphery of the fixing block. A fixing bolt is threadedly connected inside the connecting block. A rotating disk is fixedly connected to the top of the fixing bolt. The rotating disk is disposed at the top of the limiting ring. A connecting frame is fixedly connected to the front side of the locking block. A plug rod is slidably connected inside the connecting frame. The rear side of the plug rod is inserted into the interior of the fixing block. A pull ring is fixedly connected to the front side of the plug rod. A spring is sleeved around the plug rod.

[0009] Preferably, the fixing bolt passes through the inside of the limiting ring and the locking block. The limiting ring, the locking block and the connecting block are respectively provided with movable grooves, and the three fixing grooves correspond to each other. The fixing bolt is threaded into the movable groove, which facilitates the fixing bolt to move up and down under the action of the fixing groove.

[0010] Preferably, the front side of the spring is fixedly connected to the rear side of the pull ring, and the rear side of the spring is fixedly connected to the front side of the connecting frame, so as to ensure the stability of the insertion rod under the action of the spring.

[0011] Preferably, the rear side of the insertion rod extends through the interior of the locking block. The locking block and the fixing block each have a slot, and the two slots correspond to each other. The rear side of the insertion rod is inserted into the slot, which facilitates the fixing block to be limited under the action of the insertion rod, thus ensuring the stability of the connecting block.

[0012] Preferably, the bottom of the rotating disk is in contact with the top of the limiting ring, and a rubber pad is provided on the top of the limiting ring to ensure that the rotating disk and the limiting ring are in contact and will not wear out under the action of the rubber pad.

[0013] Preferably, the limiting mechanism includes a connecting shaft, which is threadedly connected to the inside of the connecting block. A knob is fixedly connected to the front side of the connecting shaft, and a rotating block is rotatably connected to the rear side of the connecting shaft. A fixed sleeve is rotatably connected to the periphery of the rotating block, and a clamping plate is fixedly connected to the rear side of the fixed sleeve. The clamping plate is slidably connected to the inside of the fixing bolt, and a limiting rod is fixedly connected to the rear side of the clamping plate.

[0014] Preferably, the fixing sleeve and the clamping plate are slidably connected inside the connecting block, and the clamping plate is arc-shaped, which facilitates the limiting effect of the fixing bolt under the action of the clamping plate.

[0015] Compared with the prior art, this utility model provides a linkage T-shaped locking device, which has the following beneficial effects:

[0016] 1. This linkage T-shaped locking device, through its locking mechanism, allows for locking of objects by first inserting a fixing block into the locking block, connecting the connecting block and the locking block in a T-shape. The fixing block is limited by the insertion rod, spring, and pull ring, ensuring stability between the connecting block and the locking block. This also facilitates replacement of the connecting block or locking block, preventing wear and tear from affecting the locking effect over time. Furthermore, it provides a linkage effect, sliding the connecting block and locking block into the groove of the structure or profile to be locked, and then connecting the fixing bolts by threading them together. The connection between the rotating disc and the fixing bolt, located inside the connecting block, allows the fixing bolt to be screwed in and out simply by rotating the rotating disc. This simple and labor-saving operation greatly improves the efficiency of locking and loosening. The fixing bolt passes through the limiting ring, locking block, and connecting block, and is connected to the corresponding movable grooves by threads, providing strong fastening force to ensure that it will not loosen due to vibration or external force during the locking process. A rubber pad is set on the top of the limiting ring, which can reduce the wear generated when the rotating disc rotates and also act as a buffer to reduce the damage to the device caused by vibration and extend the service life of the device.

[0017] 2. This linkage T-shaped locking device, through the setting of the limiting mechanism, drives the connecting shaft to rotate by rotating the knob, thereby adjusting the position of the clamping plate and the limiting rod. The clamping plate is arc-shaped and slides against the inner side of the fixing bolt, which can more accurately limit the fixing bolt. Through the clamping plate and the limiting rod, and the limiting rod being inserted into the fixing bolt, the fixing bolt is effectively prevented from rotating during operation, ensuring the stability of the locking operation.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a linkage T-shaped locking device, including a limiting ring 1, a locking mechanism 2 at the bottom of the limiting ring 1, and a limiting mechanism 3 at the front side of the locking mechanism 2;

[0030] The locking mechanism 2 includes a connecting block 21, which is located at the bottom of the limiting ring 1. A fixing block 24 is fixedly connected to the bottom of the connecting block 21. A locking block 25 is inserted into the periphery of the fixing block 24. A fixing bolt 23 is threadedly connected inside the connecting block 21.

The rear side of the plug rod 29 is inserted into the interior of the fixing block 24. A pull ring 27 is fixedly connected to the front side of the plug rod 29. A spring 28 is sleeved around the plug rod 29.

[0031] The fixing bolt 23 passes through the limiting ring 1 and the locking block 25. The limiting ring 1, the locking block 25 and the connecting block 21 are respectively provided with movable grooves, and the three fixing grooves correspond to each other. The fixing bolt 23 is threaded into the movable groove, which facilitates the fixing bolt 23 to move up and down under the action of the fixing groove. The front side of the spring 28 is fixedly connected to the rear side of the pull ring 27, and the rear side of the spring 28 is fixedly connected to the front side of the connecting frame 26, which facilitates the stability of the insertion rod 29 under the action of the spring 28.

[0032] The rear side of the insertion rod 29 passes through the interior of the locking block 25. The locking block 25 and the fixing block 24 are respectively provided with slots, and the two slots correspond to each other. The rear side of the insertion rod 29 is inserted into the slot, which facilitates the fixing block 24 to be limited under the action of the insertion rod 29, ensuring the stability of the connecting block 21. The bottom of the rotating disk 22 is in contact with the top of the limiting ring 1, and the top of the limiting ring 1 is provided with a rubber pad, which facilitates the contact between the rotating disk 22 and the limiting ring 1 under the action of the rubber pad, so that no wear occurs.

[0033] Example 2

[0034] Please see Figure 1-5 Furthermore, based on Embodiment 1, the limiting mechanism 3 further includes a connecting shaft 32, which is threadedly connected to the inside of the connecting block 21. A knob 31 is fixedly connected to the front side of the connecting shaft 32, and a rotating block 33 is rotatably connected to the rear side of the connecting shaft 32. A fixing sleeve 34 is rotatably connected to the periphery of the rotating block 33. A clamping plate 35 is fixedly connected to the rear side of the fixing sleeve 34.

The fixing sleeve 34 and the clamping plate 35 are slidably connected to the inside of the connecting block 21, and the clamping plate 35 is arc-shaped, which facilitates the limiting effect on the fixing bolt 23 under the action of the clamping plate 35.

[0035] In actual operation, when this device is used and it is necessary to lock the object, pull the pull ring 27 forward to move the insertion rod 29 and deform the spring 28, inserting the fixing block 24 into the locking block 25, so that the connecting block 21 and the locking block 25 are connected in a T-shape. When the insertion is completed, release the pull ring 27, and the spring 28 will return to its original position, so that the insertion rod 29 can be inserted into the locking block 25 and the fixing block 24, ensuring the stability between the connecting block 21 and the locking block 25, and at the same time facilitating the replacement of the connecting block 21 or the locking block 25, preventing wear from affecting the locking effect after long-term use;

[0036] The connecting block 21 and locking block 25 are slidably connected to the inside of the structure or profile groove that needs to be locked. The fixing bolt 23 is threaded into the inside of the connecting block 21, and the bottom thread of the fixing bolt 23 is threaded into the inside of the structure or profile groove that needs to be locked. The connection design between the rotating disk 22 and the fixing bolt 23 allows the fixing bolt 23 to be screwed in and out simply by rotating the rotating disk 22. The operation is simple and labor-saving, which greatly improves the efficiency of locking and loosening. The fixing bolt 23 passes through the limiting ring 1, locking block 25 and connecting block 21, and is threaded into the corresponding movable grooves, which can provide strong fastening force to ensure that it will not loosen due to vibration or external force during the locking process. The top of the limiting ring 1 is equipped with a rubber pad, which can reduce the wear generated when the rotating disk 22 rotates, and also play a buffering role, reducing the damage to the device caused by vibration and extending the service life of the device.

[0037] When the fixing bolt 23 is locked, the connecting shaft 32 is rotated by rotating the knob 31, thereby adjusting the position of the clamping plate 35 and the limiting rod 36. The clamping plate 35 is arc-shaped and slides against the inner side of the fixing bolt 23, which can more accurately limit the fixing bolt 23. Through the clamping plate 35 and the limiting rod 36, and the limiting rod 36 is inserted into the fixing bolt 23, the fixing bolt 23 is effectively prevented from rotating during operation, ensuring the stability of the locking operation.
