Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness processing equipment, specifically a locking device. Background Technology

[0002] In recent years, with the large-scale popularization and development of new energy vehicles, the demand for automotive wiring harness processing equipment has been increasing, and the demand for locking devices in wiring harness processing equipment is also very high. In some wiring harness processing equipment, blades, cylinders or other components need to be able to be adjusted and locked back and forth. Although the company has many locking devices, the components on the current wiring harness processing equipment workbench are arranged relatively compactly, and the existing locking devices are not suitable. Therefore, a new type of locking device is needed. Summary of the Invention

[0003] This utility model provides a locking device that inserts from the front to achieve locking, occupies little space, and is convenient for later adjustment.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A locking device includes a base plate, a fixed seat, a locking block, and a locking screw. A T-shaped through groove is provided at one end of the front side of the base plate. The fixed seat is movably mounted on the T-shaped through groove via two rectangular sliders. The locking block is movably mounted in the T-shaped through groove and located between the two rectangular sliders. The locking screw passes through the rectangular sliders, the locking block, and the rectangular sliders to lock the fixed seat.

[0006] Preferably, the two rectangular sliders are spaced apart at the bottom of the fixing base, and the rectangular slider on the front side is flush with the front side of the fixing base. The locking block is a convex block structure, and the locking screw passes through the front rectangular slider, the locking block and the rear rectangular slider in sequence to lock the fixing base.

[0007] Preferably, the locking screw is integrally formed by a threaded shank, a tapered shank, and a positioning shank, and the diameter of the bolt shank is larger than the diameter of the positioning shank; the locking block has a tapered through hole along the length of the T-shaped through groove, the front rectangular slider has a threaded through hole that matches the large diameter end of the tapered through hole, and the rear rectangular slider has a positioning through hole that matches the small diameter end of the tapered through hole.

[0008] Preferably, the locking screw has an internal hexagonal hole on the front side of the threaded shank.

[0009] Compared with the prior art, the advantages of this utility model are as follows: This locking device has a simple structure, strong practicality, can be inserted from the front to achieve locking, and is especially suitable for arrangement in relatively compact positions. Moreover, the locking is firm and the locking position is convenient and adjustable. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described below in conjunction with specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the scope of this patent. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art.

[0016] like Figures 1-4 As shown, the locking device of this utility model includes a base plate 1, a fixing seat 2, a locking block 3, and a locking screw 4. A T-shaped through groove 5 is provided at one end of the front side of the base plate 1. The fixing seat 2 is movably mounted on the T-shaped through groove 5 via two rectangular sliders 6 and can slide back and forth. The locking block 3 is movably mounted within the T-shaped through groove 5 and located between the two rectangular sliders 6. The locking screw 4 passes through one rectangular slider 6, the locking block 3, and the other rectangular slider 6 from the outside to lock the fixing seat 2. The fixing seat is used for mounting and fixing blades, cylinders, or other components. Its structure is not limited. Before locking, the fixing seat can slide back and forth in the T-shaped through groove of the base plate to achieve locking at different positions, thereby enabling the back-and-forth adjustment of the blades, cylinders, or other components arranged on the fixing seat.

[0017] Specifically, two rectangular sliders 6 are spaced apart at the bottom of the fixed base 2, and the rectangular slider 6 on the front side is flush with the front side of the fixed base 2. The locking block 3 is a convex block structure, and its width and height are both smaller than the T-shaped through slot. The locking screw 4 passes through the front rectangular slider 6, the locking block 3, and the rear rectangular slider 6 in sequence to lock the fixed base 2.

[0018] In the above description, the locking screw can be a screw with an externally threaded rod. Correspondingly, the locking block and the two rectangular slides have threaded through holes. In use, the pad is inserted into the bottom of the T-shaped slide to push the locking block upward, so that the threaded through hole on the locking block corresponds to the threaded through hole of the two rectangular slides. Then, the locking screw is threaded in, so that the steps on both sides of the locking block can firmly press against the steps on both sides of the bottom of the T-shaped slide, thereby achieving the locking of the fixing seat.

[0019] However, the above locking process is relatively cumbersome. In order to achieve quick locking without adjusting the locking block, such as... Figure 2 , Figure 4 As shown, in this embodiment, the locking screw is designed as follows: The locking screw 4 is integrally formed by a threaded shank 41, a tapered shank 42, and a positioning shank 43, and the diameter of the bolt shank 41 is larger than the diameter of the positioning shank 43. Correspondingly, a tapered through hole 7 is provided on the locking block 3 along the length direction of the T-shaped through groove 5. The tapered through hole 7 is adapted to the tapered shank 42. A threaded through hole 8 adapted to the large diameter end of the tapered through hole is provided on the front rectangular slider 6. The threaded through hole 8 is adapted to the threaded shank 41. A positioning through hole 9 adapted to the small diameter end of the tapered through hole is provided on the rear rectangular slider 6. The positioning through hole 9 is adapted to the positioning shank 43.

[0020] The locking block is designed with a tapered through-hole, eliminating the need for the workpiece to lift the locking block during locking, thus achieving the locking of the fixed seat. Specifically, when the locking screw passes from the front rectangular slider to the tapered part of the locking block, its tapered rod design allows it to smoothly enter the smaller diameter end of the tapered part and partially enter the positioning through-hole of the rear rectangular slider. This process naturally lifts the locking block upwards, causing the steps on both sides of the locking block to fit tightly against the steps on both sides of the bottom of the T-shaped through-slot. At this point, the fixed seat is relatively locked. Then, rotating the locking screw allows its positioning rod to continue entering the positioning through-hole without dislodging, firmly fixing the fixed seat to the base plate.

[0021] Furthermore, the front side of the threaded shank 41 of the locking screw 4 is provided with an internal hexagonal hole 10, which facilitates the insertion of a wrench for tightening.

[0022] Figures 1-4 The diagrams shown illustrate the locking state of the locking device. In use, first slide the locking block into the T-slot, then place the rectangular slider at the lower end of the fixing seat into the T-slot, clamping the locking block between the two rectangular sliders. Move the fixing seat to the appropriate position, and insert the locking screw from the outside into the threaded through hole of the front rectangular slider, the tapered through hole of the locking block, and the positioning through hole of the rear rectangular slider. Then rotate the locking screw to lock the fixing seat to the base plate.

[0023] In addition, the current base plate is the one on which the locking device is currently used. This base plate also has several other grooves, through slots, and openings, mainly used to fix other modules. Of course, the shape and arrangement of the base plate may vary depending on the situation and are not specifically limited.
