Description

Technical Field

[0001] This utility model relates to the field of security tool technology, and more specifically, it relates to a security steel fork. Background Technology

[0002] In public safety, law enforcement patrols and other situations, security tools need to be able to be deployed quickly and respond flexibly. Existing similar devices often have fixed connection methods in actual use, making it difficult to disassemble the connection between the fork and the handle. When users need to complete equipment preparation or adjust the equipment in a short time, the complex connection structure not only increases the difficulty of operation, but also reduces the response efficiency, making it difficult to meet the dual requirements of speed and convenience in emergency scenarios.

[0003] During the execution of a task, it may be necessary to change different types of forks depending on the target object to adapt to differences in control range, contact method, etc. However, existing devices usually lack a convenient replacement mechanism. The connection between the fork and the main body is relatively fixed. Once damaged or needing replacement, it often requires the use of tools or even disassembly of multiple parts, which is cumbersome and time-consuming. This structural limitation not only reduces the maintenance efficiency of the equipment but also affects the overall practical application effect. Utility Model Content

[0008] The present invention is further configured such that a positioning block is provided on the outer wall of the snap-fit ​​rod, and a positioning hole is provided on the inner side of the snap-fit ​​sleeve. Both the positioning block and the positioning hole are polygonal to ensure accurate positioning between the snap-fit ​​rod and the snap-fit ​​sleeve and to prevent loosening or misalignment during use.

[0009] The present invention is further configured such that multiple sets of sliding grooves are inclinedly arranged inside the snap-fit ​​sleeve and slidably connected to the slider, which improves the docking accuracy and stability of the snap-fit ​​block and the snap-fit ​​groove. At the same time, the sliding design of the slider enhances the smoothness of operation and avoids the jamming phenomenon during snap-fit.

[0010] The present invention is further configured such that each of the multiple sets of card slots has a clearance groove at its top, which effectively avoids the blockage of the card block during the carding process, promotes the smooth insertion and fixation of the carding rod, and improves the connection efficiency.

[0011] The present invention is further configured such that a compression spring is connected inside the snap-fit ​​rod, and an abutment plate is connected to the top of the compression spring. The compression spring provides elastic support to the snap-fit ​​rod, which helps to reduce impact force, protect the snap-fit ​​components from damage, and ensure the smoothness of the snap-fit ​​process.

[0012] The present invention is further provided that a compression spring is provided between the sliding sleeve and the outer wall of the snap-fit ​​sleeve. Multiple sets of compression springs are provided. Through the elastic action of multiple sets of compression springs, the locking mechanism is guaranteed to have sufficient fastening force during operation, thereby improving the safety and stability of the connection.

[0013] The present invention is further provided that a reset spring is connected between each of the multiple sets of card blocks and the inner wall of the card sleeve.

[0014] The present invention is further configured such that a thrust bearing is installed on the top surface of the threaded sleeve. The thrust bearing reduces the friction during the rotation of the thread, improves the smoothness of rotation, and extends the service life of the threaded sleeve and other components.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a security steel fork with the following advantages:

[0017] 1. This security steel fork features a snap-fit ​​mechanism that enables quick and secure connection between the handle and the fork head. By utilizing the engagement of the snap-fit ​​sleeve and the snap-fit ​​rod, combined with the sliding mechanism of the groove and the slider, the snap-fit ​​block can be accurately positioned in the slot, enhancing the stability and reliability of the connection. At the same time, the positioning block on the snap-fit ​​rod engages with the positioning hole inside the snap-fit ​​sleeve to effectively prevent rotational misalignment.

[0018] 2. The locking mechanism works by rotating the threaded sleeve to drive the sliding sleeve to slide along the movable groove, and the push ring further pushes the locking block into the slot to achieve locking. The thrust bearing reduces operating friction and improves smoothness of use, while the threaded connection ensures long-lasting and stable locking.

[0019] 3. The overall structure is equipped with multiple spring systems, including compression springs, squeeze springs, and return springs. Through a multi-point elastic drive and reset mechanism, it is ensured that during disassembly, only the threaded sleeve needs to be loosened to release the pushing force of the sliding sleeve on the locking block. The spring reset automatically disengages the locking relationship, and the compression spring pushes the locking rod to pop out of the locking sleeve, thereby achieving a fast, safe, and reliable disassembly operation, significantly improving on-site operation efficiency and emergency response capabilities.

[0029] Please see Figures 1-5 A security steel fork includes a handle 1 and a fork head 2. A locking mechanism is provided between the handle 1 and the fork head 2. The locking mechanism includes a locking sleeve 3, a locking rod 4, a sliding groove 5, a slider 6, a locking block 7, a locking groove 8, and a locking mechanism. The locking sleeve 3 is fixed to the top of the handle 1, the locking rod 4 is fixed to the bottom of the fork head 2 and inserted into the locking sleeve 3, multiple sets of sliding grooves 5 are provided on the inner side of the locking sleeve 3, the slider 6 slides in multiple sets of sliding grooves 5, the locking block 7 is fixed on the inner side of multiple sets of sliders 6, and multiple sets of locking grooves 8 are provided on the outer wall of the locking rod 4. The locking mechanism includes a movable groove 9, a sliding sleeve 10, a push ring 11, and a threaded sleeve 12. Multiple sets of movable grooves 9 are provided on the outer wall of the locking sleeve 3, the sliding sleeve 10 slides in multiple sets of movable grooves 9, the push ring 11 is fixed on the inner side of the sliding sleeve 10, and the threaded sleeve 12 is threadedly connected to the outer side of the locking sleeve 3.

[0030] The outer wall of the snap-fit ​​rod 4 is provided with a positioning block 13, and the inner side of the snap-fit ​​sleeve 3 is provided with a positioning hole 14. Both the positioning block 13 and the positioning hole 14 are set as polygons, and the anti-rotation positioning principle is realized by utilizing the complementary restraint effect of the polygon structure.

[0031] Multiple sets of sliding grooves 5 are inclinedly arranged inside the snap-fit ​​sleeve 3 and slidably connected with the slider 6. The inclined guiding sliding principle is realized through the guiding cooperation between the sliding grooves 5 and the slider 6.

[0032] Each of the multiple card slots 8 has a clearance slot 15 at its top. By setting the clearance slot 15 at the top of the card slot 8, space is provided for the card block 7, thus realizing the principle of interference avoidance.

[0033] A compression spring 16 is connected inside the snap-fit ​​rod 4. An abutment plate 17 is connected to the top of the compression spring 16. The compression spring 16 provides outward elastic force, which is transmitted to the snap-fit ​​end by the abutment plate 17, realizing the principle of elastic ejection.

[0034] A compression spring 18 is provided between the sliding sleeve 10 and the outer wall of the snap sleeve 3. Multiple sets of compression springs 18 are provided, and the multiple sets of compression springs 18 provide continuous elastic force to push the sliding sleeve 10 outward, realizing the principle of elastic pre-tightening.

[0035] Each set of card blocks 7 is connected to the inner wall of the card sleeve 3 with a reset spring 19. When the reset spring 19 is released, it drives the card block 7 to return to its original position, realizing the principle of automatic reset.

[0036] A thrust bearing 20 is installed on the top surface of the threaded sleeve 12. The thrust bearing 20 is used to reduce the axial friction force generated when the threaded sleeve 12 rotates, so as to realize the principle of low friction rotation.

[0037] In this embodiment, when it is necessary to connect the fork head 2 and the handlebar 1, the locking rod 4 is inserted into the locking sleeve 3, and the positioning block 13 and the positioning hole 14 are used for positioning and insertion. The abutting rod abuts against the handlebar 1 and squeezes the compression spring 16. The rotating threaded sleeve 12 pushes the sliding sleeve 10 through the thrust bearing 20, so that the sliding sleeve 10 slides along multiple sets of movable grooves 9 and compresses multiple sets of compression springs 18. At the same time, the sliding sleeve 10 drives the push ring 11 to push multiple sets of locking blocks 7. The multiple sets of locking blocks 7 slide along the sliding groove 5 through the slider 6 and engage in the locking groove 8 to fix the locking rod 4. Tighten the threaded sleeve 12 to lock the locking rod 4 and complete the locking.

[0038] More specifically, when disassembly is required, loosening the threaded sleeve 12 releases the thrust bearing 20 from pressing against the sliding sleeve 10. The sliding sleeve 10 is pushed along the multiple movable grooves 9 by the reset of the multiple compression springs 18, so that the push ring 11 releases its contact with the multiple locking blocks 7. The locking blocks 7 are pulled by the multiple reset springs 19 so that they slide along the sliding groove 5 through the slider 6 and disengage from the locking groove 8 along the relief groove 15, releasing the locking of the locking rod 4. Then, the locking rod 4 is pushed away from the locking sleeve 3 by the reset of the compression spring 16, completing the disassembly of the fork head 2.

[0039] In summary, when the entire equipment is in use or operation: when it is necessary to connect the fork head 2 and the handle bar 1, the locking rod 4 is inserted into the locking sleeve 3, and the locking is positioned and inserted through the positioning block 13 and the positioning hole 14. The abutting rod abuts against the handle bar 1 and squeezes the compression spring 16. The rotating threaded sleeve 12 pushes the sliding sleeve 10 through the thrust bearing 20, so that the sliding sleeve 10 slides along multiple sets of movable grooves 9 and compresses multiple sets of compression springs 18. At the same time, the sliding sleeve 10 drives the push ring 11 to push multiple sets of locking blocks 7. The multiple sets of locking blocks 7 slide along the sliding groove 5 through the slider 6 and engage in the locking groove 8 to fix the locking rod 4. Tighten the threaded sleeve 12 to lock the locking rod 4 and complete the locking.

[0040] When disassembly is required, loosen the threaded sleeve 12 to release the thrust bearing 20 from the sliding sleeve 10. The sliding sleeve 10 is pushed to slide along the multiple movable grooves 9 by the multiple compression springs 18, so that the push ring 11 releases its contact with the multiple locking blocks 7. The locking blocks 7 are pulled by the multiple reset springs 19 so that they slide along the sliding groove 5 through the slider 6 and disengage from the locking groove 8 along the relief groove 15, releasing the locking of the locking rod 4. Then, the locking rod 4 is pushed to disengage from the locking sleeve 3 by the compression spring 16, completing the disassembly of the fork head 2.
