Pressing fixing device for door handle of switch box suitable for different box door plate thicknesses

Technical Field

The utility model belongs to the technical field of the technique that is relevant with switch box (or called electric box, block terminal), especially indicate a switch chamber door handle is suitable for the thick compel pressure fixing device of different chamber door boards.

Background

The switch box door handle lock mainly refers to a buckling lock structure for a box door of an electric box or a distribution box. As shown in fig. 5 and 6, the handle lock 90 is installed in a predetermined opening of the door 91, the frame plate 92 of the lock, the button 93 thereof and the spring handle 94 are located on the front surface of the door 91, the lock body 95 and the locking piece 96 thereof are located on the rear surface of the door 91, a fixing plate 98 is installed by a screw 97 from the rear surface of the door 91 toward the lock body 95, and the fixing plate 98 is provided with attaching stoppers 99 at the left and right portions thereof for clamping and positioning the door 91 in cooperation with the frame plate 92, thereby installing the handle lock 90 on the opening and closing door 91. Pressing the button 93 causes the spring handle 94 to spring up, and pulling the spring handle 94 causes the latch plate 96 to move away from the latch hole (not shown) of the switch box, so that the door can be opened. Conversely, the sprung spring handle 94 is pressed back into position, the latch tab 96 snaps into the latch hole and the door is locked.

The fixing plate 98 and the screw 97 are inconvenient to mount the handle lock 90 on the door, and the problem of loosening and unstable shaking of the handle lock 90 is easily caused by the untightening of the screw 97. In addition, the fixing plate 98 and the screw 97 are usually locked at the middle or a lower position of the main body 95 of the lock, which easily causes a loose gap between the upper edge and the lower edge of the handle lock 90 and the door. These problems affect whether the locking piece 96 can be smoothly inserted into or removed from the locking hole, in other words, the problems concern whether the door can be smoothly opened or closed.

Detailed Description

The following will refer to the related drawings to further explain the embodiments of the pressing and fixing device of the door handle of the switch box of the present invention, which is suitable for different plate thicknesses of the box door. Various objects in the embodiments are illustrated in scale, size, amount of distortion or displacement suitable for illustration, rather than in scale of actual components, as previously described. And like and symmetrically configured elements in the remaining embodiments are indicated by like reference numerals. In addition, the directional terms "front, rear, left, right, up, down, inside, outside" and the like in the following description of the embodiments are used in the specific view directions, and should not be construed as limiting the present invention.

Referring to fig. 1 to 4, the pressing fixing device for a door handle of a switch of the present invention, which is suitable for different thicknesses of door panels, includes a handle lock 10, an abutting member 20, and an adjusting member 30.

The handle lock 10 is installed in a predetermined opening of a door 11. A frame plate 12 of the handle lock 10 and an opening and closing handle 13 thereof are disposed on a front surface 111 of the door 11, and a lock main body 14 of the handle lock 10 and a locking piece 15 thereof are disposed on a rear surface 112 of the door 11 after passing through the opening.
