Technical Field

[0001] The present invention relates to the technical field of electrical switches, in particular to a panel type isolating switch. Background Art

[0002] Traditional electrical switches or potential switching devices are usually purely manually operated switches, which require manual positioning of the switch position and then locking. Since there is no power assistance during the rotation process, the operation process is very difficult, and since it is manually positioned, inaccurate positioning is prone to occur. At the same time, since the switch locking structure usually uses a locking mechanism for locking, it is easy for the switch to not lock after unlocking. Therefore, based on the above problems, it is necessary to design a new type of transfer switch with self-locking and precise positioning. Summary of the Invention

DETAILED DESCRIPTION

[0022] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods;

The cam 3 is connected to the front panel 1 and the rear panel 1 and the rear panel 1 is connected, and the cam 3 is connected to the front panel 1 and the rear panel 1. The cam 3 is connected to the front panel 1 and the rear panel 1 and the rear panel 1 is connected, and the cam 3 is connected to the front panel 1 and the rear panel 1.

[0025] The limiting device includes: a bearing arm 4, a tension spring 5, and a positioning disc 4 fixedly mounted on the handle square rod 3; one end of the bearing arm 4 is hinged to the lower end surface of the front panel 2, and the other end is hooked on one end of the tension spring 5, the other end of the tension spring 5 is fixed to the front panel 2, and a bearing 4-1 is installed at the middle position of the bearing arm 4; the positioning disc 6 is provided with a plurality of limiting slots 6-1 for limiting and a plurality of locking slots 6-2 for self-locking; the bearing 4-1 is fitted in the locking slots 6-2; the bearing arms 4 are arranged in parallel, and the bearing 4-1 is located between the two bearing arms 4;

[0026] The positioning disc 6 is provided with three limiting slots 6 - 1 and three locking slots 6 - 2 .

[0027] The self-locking device includes a lock hook 7 hinged on the front panel 2; a lock column 7-1 is installed at the hinged end of the lock hook 7, a return compression spring 7-3 is installed on the upper end of the installed lock column 7-1, and the lower end extends out of the panel 1, and a lock core 7-2 is provided at the end of the lock column 7-1; the end of the lock hook 7 can cooperate with the locking slot 6-2 on the positioning disc 6, and the lock core 7-2 is a square structure; the lock column is connected to the lock hook, and when the lock core is rotated, the lock hook is driven to rotate;

[0028] The panel and the front panel are fixed to each other through a support column. When in use, the device to be converted is fixedly mounted on the handle square rod, and the potential is switched by rotating the handle square rod. The main function of this device is to limit and lock the rotation angle of the handle square rod. The limit and self-locking are achieved by the grooves set in the positioning disc, which can realize the dual functions of self-locking and accurate positioning.

[0029] When the switch is in use, the four-corner key is used to rotate the lock cylinder, and the lock cylinder drives the lock hook to rotate, leaving the locking slot of the positioning disc to complete the unlocking; then the handle is turned to drive the positioning disc and the movable knife to rotate. Because the positioning disc is a cam structure, under the action of the bearing, the bearing arm rotates with the hinge end as the center, and the tension spring stretches. When the bearing passes the high point of the positioning disc, it is subjected to the tension and the force of the operator and enters the limit groove of the next position. At the same time, the handle square rod and other mechanisms are driven to rotate to the other corresponding proceeding end to realize the switching of the main circuit. At the same time, the four-corner key is released, and the lock hook is acted upon by the torsion spring to enter the positioning disc, completing the self-locking of the switch. The limit groove and locking groove of this device are set according to the actual working conditions. The matching position of the bearing arm and each limit groove corresponds to the corresponding switch switching position.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the invention.
