Description

Technical Field

[0001] The invention belongs to the technical field of clamp design, and in particular relates to a quick slot locking device. Background Art

[0002] The locking device is generally used to temporarily lock two or more parts in a detachable manner, and is generally used in scenarios such as workpiece processing and assembly. Currently, the most commonly used and convenient locking device is generally a structure in which a bolt and a nut are combined.

[0003] For a long time, the structure of bolts and nuts has been the choice of most users due to its convenient operation, low cost and good effect. However, the installation or removal process of bolts and nuts takes a relatively long time. In addition, the bolts use a threaded rod to be screwed with a hexagonal nut. Due to the insufficient bearing pressure of the nut against the locking object, the locking structure often becomes loose or even falls off. Summary of the invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a quick slot locking device, which is simple to clamp and easy to process, and is convenient for quick installation and disassembly.

The head end of the claw clamp top rod 5 is provided with a circular buckle matching the circular groove, so as to realize axial fixation of the adapter 4 and the claw clamp top rod 5, and free circumferential rotation.

[0009] An axial long hole 51 is arranged along the center of the tail of the claw forceps top rod 5, and an axial sliding groove 52 penetrating the long hole 51 is arranged on the side wall. At the same time, a fan-shaped opening 53 is opened at the end of the claw forceps top rod 5, and the rotating handle 6 is movably connected at the fan-shaped opening 53 so that the rotating handle 6 can be folded.

[0023] The embodiments of the present invention are described in detail below with reference to the accompanying drawings and examples.

[0024] like Figure 1 and Figure 2As shown, the present invention is a quick slot locking device, which mainly includes a claw clamp 2, a claw clamp mandrel 5, a main cavity 1 and a slot 9 matched with the claw clamp 2.

[0025] In the specific structure, refer to Figure 1 , Figure 2 and Figure 3 The claw clamp 2 is composed of two claw clamp blocks, which are simultaneously hinged to the head end of the adapter 4 through the claw clamp shaft 3. The outer contour of the claw clamp 2 in contact with the main cavity 1 is a smooth curve, which is convenient for the extension and retraction of the claw clamp.

[0026] refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 A hinge hole is provided at the front end of the adapter 4, which is hinged to the claw clamp shaft 3, and a circular groove is opened at the end. The head end of the claw clamp top rod 5 is provided with a circular buckle matching the circular groove, so as to realize axial fixation of the adapter 4 and the claw clamp top rod 5, and free circumferential rotation.

[0027] refer to Figure 1 , Figure 2 and Figure 5 The front outer wall of the claw pliers top rod 5 is provided with an external thread, an axial long hole 51 is provided along the center of the tail of the claw pliers top rod 5, and the side wall is provided with an axial sliding groove 52 penetrating the long hole 51, which is movably connected with the rotating handle 6. The rotating handle 6 can be inserted into the claw pliers top rod 5 for easy storage. At the same time, a fan-shaped opening 53 is opened at the end of the claw pliers top rod 5, so that the rotating handle 6 can be extended and folded, providing a lever to save effort.

[0028] refer to Figure 1 , Figure 2 and Figure 6 The side wall of the rotating handle 6 has two connecting columns, and the use of the concealable rotating handle 6 makes manual locking convenient and labor-saving.

[0029] refer to Figure 1 , Figure 2 and Figure 7 The main cavity 1 is a long cylindrical part. The claw 2, the claw shaft 3, the adapter 4 and the claw mandrel 5 are all located in the main cavity 1. The front side wall of the main cavity 1 is provided with a through hole for the claw 2 to extend and retract. The claw 2 is extended and retracted here. The front inner side wall of the main cavity 1 is provided with an internal thread, which cooperates with the external thread of the claw mandrel 5. The rotating handle 6 can realize the screwing and self-locking of the claw mandrel 5 in the main cavity 1, and then realize the control of the claw 2 from extending and retracting from the through hole, so as to achieve the purpose of locking. The outer side wall of the middle section of the main cavity 1 is provided with an external thread.

[0030] When clamping the workpiece, one end of the claw 2 is extended into the clamping groove 9 through the workpiece, and the claw 2 is squeezed out by the thread transmission by rotating the handle 6 to hook the clamping groove 9.

[0031] refer to Figure 1 , Figure 2 and Figure 8 The present invention also includes a locking rotor 7, which has a through hole in the middle, and an internal thread is provided on the inner wall of the through hole. The internal thread of the locking rotor 7 cooperates with the external thread of the main cavity 1. The locking rotor 7 is rotated to tighten the workpiece to be locked.

[0032] Reference Figure 2 At this time, the specific process of locking the workpiece is as follows:

[0033] Insert the claw 2 into the slot through the workpiece, pull out the rotating handle 6 from the claw top rod 5 and fold it. Due to the limitation of the slide slot, the rotating handle 6 will not be pulled out. Rotate the rotating handle 6 to drive the rotation of the claw top rod 5. Under the action of the transmission thread that cooperates with the claw top rod 5 and the main cavity 1, the claw top rod 5 presses the claw 2 on the adapter 4 forward. Due to the smooth curved contour of the claw 2 and the extrusion of the head of the main cavity 1, the claw 2 will slowly open and hook the slot 9 in the reverse direction. During the locking process, the locking rotor 7 is rotated to tighten the workpiece to be locked.

[0034] Simple changes and replacements without changing the basic creative content of the present invention are considered to be the same creation. The above description of the disclosed embodiments enables professionals and technicians in the field to implement or use the present invention. Other modifications to these embodiments will be obvious to professionals and technicians in the field, and the general principles herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the examples shown herein, but will conform to the widest range consistent with the principles and novel features disclosed herein.
