Description

Technical Field

[0001] The utility model relates to the technical field of wiring clamp application, in particular to an automatically retractable multifunctional wiring clamp. Background Art

[0002] A terminal clamp is a device used to connect wires or cables. Its main function is to provide electrical connection and ensure the conduction of current by clamping the wire. In this regard, the multifunctional terminal clamp with automatic retraction has significant advantages. Its automatic retraction design makes installation and use more convenient, without the need for manual adjustment to adapt to wires of different diameters. In addition, the multifunctional design makes it suitable for various electrical systems and equipment, while the use of high-quality materials ensures the reliability and stability of the connection. The flexibility and safety of this terminal clamp make it widely used in different fields such as industry, construction, and automobiles, helping to improve the performance and overall safety level of electrical systems.

[0003] After searching, the announcement number: CN211404770U discloses an automatically retractable multifunctional terminal clamp, including a shell, a terminal head, a wire hole, a wire outlet, a magnetic plate, a branching head, a circular plate, a rotating shaft, a bearing, a reel, a partition, a spring, a connecting rod, a wire, a movable cavity, a limit plate, a reset spring, a limit groove, a limit column and a fixing bolt. The wire can be wound around the surface of the reel, and when the branching head is pulled, the wire will move toward the outer end, thereby driving the reel to rotate. While the reel is rotating, the mainspring will be tightened, thereby generating elastic force. Under the action of the elastic force, the wire can be rewound onto the surface of the sleeve, thus achieving the purpose of automatic extension and retraction; by pulling the circular plate, the limit plate can be driven to move inside the movable cavity, so that the reset spring is compressed, and at the same time, the limit column on the side of the circular plate will move out from the limit groove on the side of the outer shell, and the wiring length can be adjusted again. After the adjustment is completed, the circular plate is loosened, and under the reaction of the reset spring, the limit column will re-engage in the limit groove. Although the wire is fastened and installed by using fixing bolts in this application, this method requires the use of installation tools when the wire needs to be replaced, which makes the installation and disassembly work more cumbersome, thereby causing a waste of time.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 - Figure 3The utility model provides an embodiment: an automatically retractable multifunctional wiring clamp, including a shell 1, a wiring head 2 is fixedly connected to the outer wall of the shell 1, a clamping block 3 is fixedly connected to the outer wall of the wiring head 2, a pressure block 4 is slidably connected to the inner wall of the wiring head 2, buckles 5 are fixedly connected to both sides of the outer wall of the pressure block 4, the buckles 5 are engaged with the outer wall of the clamping block 3, a clamping component 6 is arranged on the inner wall of the wiring head 2, a branching head 7 is arranged on the other side of the outer wall of the shell 1, and a hinge seat is fixedly connected to one side of the outer wall of the branching head 7 18, the inner wall of the hinge seat 18 is rotatably connected to a rotating plate 19, one side of the outer wall of the rotating plate 9 is fixedly connected to a spring 2 10, the lower surface of the spring 2 10 is fixedly connected to the outer wall of the branching head 7, the other side of the outer wall of the rotating plate 9 is fixedly connected to a hinge seat 2 11, and the inner wall of the hinge seat 2 11 is rotatably connected to an arc plate 12; the clamping assembly 6 includes a spring 1 601, one end of the spring 1 601 is fixedly connected to one side of the inner wall of the wiring head 2, and the other end of the spring 1 601 is fixedly connected to a sliding plate 602;

[0024] Specifically, when in use, first, the pressing block 4 is separated from the inside of the terminal head 2 by pulling the buckle 5. At this time, the cable is placed on the outer wall of the sliding plate 602, and the sliding plate 602 is fixed by the resistance force of the spring 1 601, thereby fixing the wire. Next, the pressing block 4 is covered so that the buckle 5 and the block 3 are engaged, so that the initial fixing effect of the cable can be achieved. Then, another cable is inserted into the inside of the branch head 7. At this time, by pressing one side of the rotating plate 1 9, the spring 2 10 is contracted, thereby driving the arc plate 12 to rise. This process cleverly utilizes the principle of mechanics, so that the arc plate 12 can be easily moved to a suitable position. Next, the rotating plate 1 9 is released, and the reaction force of the spring 2 10 will drive the arc plate 12 to clamp the cable. This process is both fast and stable, and can effectively fix the cable and prevent it from falling off. This design not only improves the reliability of cable fixing, but also greatly simplifies the operation process and improves work efficiency.

[0025] Reference Figure 4 , a rotating plate 2 13 is rotatably connected inside the shell 1, and a rotating column 21 is fixedly connected to the outer wall of the rotating plate 2 13; a wire 22 is arranged on the outer wall of the rotating column 21, and the wire 22 is electrically connected to the terminal 2 and the branching head 7; a tension spring 20 is fixedly connected to one side of the outer wall of the rotating plate 2 13, and one end of the tension spring 20 is fixedly connected to the inner wall of the shell 1; a fixed plate 14 is fixedly connected to one side of the outer wall of the rotating plate 2 13, and a sliding column 15 is slidably connected inside the rotating plate 2 13; a connecting plate 16 is fixedly connected to the outer wall of the sliding column 15, and a plug rod 19 is fixedly connected to one side of the outer wall of the connecting plate 16, and the plug rod 19 is slidably connected to the inside of the shell 1; a telescopic rod 17 is fixedly connected between the fixed plate 14 and the connecting plate 16, and a spring 3 18 is sleeved on the outer wall of the telescopic rod 17;

[0026] Specifically, when it is necessary to adjust or operate certain mechanical parts, the user can pull the sliding column 15 to disengage the plug rod 19 from the inside of the shell 1. This step not only releases the fixing effect of the plug rod 19 on the shell 1, but also creates conditions for the following operations. Next, by pulling the branching head 7, the user can easily drive the rotating plate 2 13 on the outer wall of the rotating column 21 to rotate. This design cleverly utilizes the principle of levers and the principle of mechanical transmission, making the rotation that may have required complex operations to achieve simple and efficient. The realization of this step not only demonstrates the importance of user-friendliness in modern mechanical design, but also reflects the designer's deep understanding and application of the laws of mechanical motion. At this time, the combination of telescopic rod 17 and spring three 18 plays a key role. When the sliding column 15 is released, the telescopic rod 17 will shrink under the action of spring three 18.

[0027] Working principle: when the wiring clamp is needed, the clamp 5 is pulled to separate the pressure block 4 from the wiring head 2, and the cable is placed on the outer wall of the sliding plate 602, and the spring 1 601 is used to fix the wire against the sliding plate 602. At this time, the clamp 4 is covered to make the clamp 5 and the clamp 3 engage, so as to achieve the effect of fixing the cable. At this time, another cable is inserted into the branching head 7, and the spring 2 10 is contracted by pressing one side of the rotating plate 1 9, so as to achieve the effect of facilitating the lifting of the arc plate 12. At this time, the rotating plate 1 9 is released, and the reaction force of the spring 2 10 drives the arc plate 12 to clamp the cable, so as to achieve the effect of fixing the cable so that it will not fall off.

[0028] Secondly, by pulling the sliding column 15, the insertion rod 19 is separated from the shell 1, and then by pulling the branch head 7, the effect of facilitating the rotation of the outer wall rotating plate 2 13 of the rotating column 21 is achieved. At this time, by loosening the sliding column 15, the telescopic rod 17 cooperates with the spring three 18 to shrink, thereby achieving the effect of fixing the tension spring 20 so that it will not reset.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
