Description

Technical Field

[0001] The invention relates to the field of door and window hook locks, and in particular to a lock hook horizontal adjustment device. Background Art

[0002] Door and window hook locks are commonly used door and window hardware. The main switching function of the hook lock is completed by the lock hook, so the accuracy of the installation position of the lock hook is required to be high. Usually, when installing the hook lock, the position of the lock hook cannot be fully taken into account. Therefore, after installing the hook lock, the position of the lock hook needs to be fine-tuned.

[0003] The commonly used lock hook adjustment structure is to place screws in the upper and lower threaded grooves. The adjustment screw causes half of the thread groove to move, thereby driving the lock hook to move. However, since the threads are divided into two halves, the adjustment sensitivity of this adjustment structure is low and it is easy to slip. In addition, in daily use, misoperation such as the user hitting the lock hook may damage half of the thread, causing the adjustment structure to be scrapped. Summary of the invention

[0004] The object of the present invention is to provide a locking hook horizontal adjustment device which ensures the adjustment sensitivity and enhances the deformation capacity of the adjustment structure.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a lock hook horizontal adjustment device, comprising an adjustment mounting seat, an adjustment mounting block and a lock hook, the adjustment mounting seat and the adjustment mounting block are matched with each other, the adjustment mounting seat is provided with a screw groove, an adjustment screw is provided in the screw groove, the adjustment mounting block is provided with a screw hole, the screw hole is matched with the adjustment screw thread, and the lock hook is fixedly connected with the adjustment mounting block. The lock hook horizontal adjustment device of the present invention is provided with an adjustment mounting seat and an adjustment mounting block, a screw hole is provided in the adjustment mounting block, a screw groove is provided in the adjustment mounting seat, and the adjustment screw is installed in the screw groove. Since the adjustment screw is limited by the screw groove and can only rotate in place, when adjusting and rotating the adjustment screw, the adjustment mounting block matched with the adjustment screw thread rotates and moves, and the adjustment mounting block drives the lock hook to move, completing the horizontal adjustment of the lock hook, the screw hole of the adjustment mounting block is provided with a complete thread, and the adjustment accuracy is guaranteed. At the same time, the setting of the overall thread greatly enhances the anti-deformation ability.

[0006] In some embodiments, the adjustment mounting seat is provided with an adjustment hole corresponding to the position of the adjustment screw. The adjustment hole is provided to facilitate rotation adjustment of the adjustment screw.

[0007] In some embodiments, the diameter of the adjustment hole is smaller than the diameter of the screw hole, which ensures that the adjustment screw will not slip out.

[0008] In some embodiments, a slide groove is provided at the bottom of the screw groove, and a protrusion is provided at the adjustment mounting block, and the protrusion is slidably matched with the slide groove. The protrusion and the slide groove are provided to ensure that the displacement path of the adjustment mounting block will not deviate during the adjustment process.

[0009] In some embodiments, the lock hook is provided with a lock hook mounting hole, the adjustment mounting block is provided with a mounting block mounting hole, and the lock hook mounting hole and the mounting block mounting hole are fixedly connected by a lock hook mounting nail. The adjustment mounting block is fixedly installed by the lock hook mounting nail so that the lock hook and the adjustment mounting block move synchronously.

[0010] In some embodiments, the lock hook is provided with a lock hook positioning hole, and the protrusion passes through the slide slot and cooperates with the lock hook positioning hole. The lock hook positioning hole is provided and cooperates with the protrusion to ensure that the displacement path of the lock hook will not deviate, thereby ensuring the overall movement of the lock hook.

[0011] The beneficial effects of the present invention are as follows: the lock hook horizontal adjustment device of the present invention is provided with a mother-and-child cooperation of an adjustment mounting block and an adjustment mounting seat, so that the screw hole in the adjustment mounting block cooperates with the adjusting screw thread in the adjustment mounting seat, and the displacement control of the adjustment mounting block is completed by rotating the adjusting screw, and at the same time, the adjustment mounting block drives the lock hook fixedly installed therewith to synchronously displace, so as to complete the horizontal adjustment of the lock hook. The screw hole in the adjustment mounting block is a complete thread, and the thread cooperation with the adjusting screw is high in precision, and the complete adjustment mounting block has a high load-bearing capacity and is not easy to deform.

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0017] like Figures 1 to 4 As shown, the locking hook horizontal adjustment device includes an adjusting mounting seat 1, an adjusting mounting block 2 and a locking hook 3. The adjusting mounting seat 1 and the adjusting mounting block 2 are in a mother-and-child relationship. The adjusting mounting seat 1 is provided with a screw groove 11, and an adjusting screw 12 is provided in the screw groove 11. The adjusting mounting block 2 is provided with a screw hole 21, and the screw hole 21 is threadedly matched with the adjusting screw 12. The locking hook 3 is fixedly connected to the adjusting mounting block 2.

[0018] The lock hook horizontal adjustment device of the present invention is provided with an adjustment mounting seat 1 and an adjustment mounting block 2, a screw hole 21 is provided in the adjustment mounting block 2, a screw groove 11 is provided in the adjustment mounting seat 1, and an adjustment screw 12 is installed in the screw groove 11. Since the adjustment screw 12 is restricted by the screw groove 11 and can only rotate in situ, when the adjustment screw 12 is adjusted and rotated, the adjustment mounting block 2 matched with the thread of the adjustment screw 12 rotates and moves, and the adjustment mounting block 2 drives the lock hook 3 to move, so as to complete the horizontal adjustment of the lock hook 3. The screw hole 21 of the adjustment mounting block 2 is provided with a complete thread, so that the adjustment accuracy is guaranteed. At the same time, the setting of the overall thread greatly enhances the anti-deformation ability.

[0022] The lock hook 3 is provided with a lock hook mounting hole 31, and the adjustment mounting block 2 is provided with a mounting block mounting hole 23. The lock hook mounting hole 31 and the mounting block mounting hole 23 are fixedly connected by a lock hook mounting nail 32. The adjustment mounting block 2 is fixedly mounted by the lock hook mounting nail 32, so that the lock hook 3 and the adjustment mounting block 2 are displaced synchronously.

[0023] The lock hook 3 is provided with a lock hook positioning hole 33, and the protrusion 22 passes through the slide slot 14 and cooperates with the lock hook positioning hole 33. The lock hook positioning hole 33 is provided and cooperates with the protrusion 22 to ensure that the displacement path of the lock hook 3 will not deviate, and the overall movement of the lock hook 3 is guaranteed.

[0024] The lock hook horizontal adjustment device of the present invention is provided with a mother-and-child cooperation of an adjustment mounting block and an adjustment mounting seat, so that the screw hole in the adjustment mounting block cooperates with the adjusting screw thread in the adjustment mounting seat, and the displacement control of the adjustment mounting block is completed by rotating the adjusting screw, and at the same time, the adjustment mounting block drives the lock hook fixedly installed therewith to synchronously displace, so as to complete the horizontal adjustment of the lock hook. The screw hole in the adjustment mounting block is a complete thread, and the thread cooperation with the adjusting screw is high in precision, and the complete adjustment mounting block has a high load-bearing capacity and is not easy to deform.
