Abstract

Provided is a pressing and fixing device for a handle lock of a switch box door. The handle lock is installed in a preset opening of the switch box door. A frame plate of the handle lock and a switch handle in the frame plate are positioned on the front surface of the box door. A main lock body of the handle lock and a locking piece of the main lock body are positioned on the rear surface of the box door after passing through the opening. The pressing and fixing device includes: a pressing buckle ring provided on the upper and lower parts of a casing of the main lock body. The pressing buckle ring includes an open annular pressing part. Each of two ends of the pressing part is curved and extended to form an elastic angle. An open end of each of two elastic bending angles is extended to form a pivot pin. The pivot pin is penetratingly pivoted in a predetermined pivot hole on the side surface of the casing. The pressing part is pushed toward the box door, and the pressing buckle ring turns over by using the two pivot pins as the axis until the pressing part contacts the box door. The elastic bending angle is compressed and deformed, so that the pressing part generates a pressing force toward the box door and presses the box door tightly.

Description

Switch box door handle lock force fastening device

The present invention relates to switch box (or claims electric box, distribution box), more specifically, is about the tightening fixing device of the handle lock of switch box door.

The so-called switch box door handle lock mainly refers to the buckle lock structure used for the box door of an electrical box or a distribution box. As shown in Fig. 1 and Fig. 2, handle lock 90 is installed in the opening of box door 91 default, and the frame plate 92 of lock and button 93 and spring handle 94 therein are positioned at the front face of this box door 91, and the main body 95 of lock and Its lock catch piece 96 is positioned at the rear portion face of this box door 91, and a fixed plate 98 is installed with screw 97 from the rear portion of box door 91 facing the direction of the main body 95 of the lock, and the left and right parts of this fixed plate 98 are provided with anti-adhesion portion 99, The fastening part cooperates with the frame plate 92 to clamp and position the box door 91 , so that the handle lock 90 is installed on the switch box door 91 . Pressing the button 93 can make the spring handle 94 pop up, pulling the spring handle 94 can activate the lock piece 96 to move away from the lock hole (not shown) of the switch box, and the door can be opened. On the contrary, the spring handle 94 that bounces up is pressed back to the position, and the locking plate 96 is buckled in the locking hole, and the door is locked.

It is inconvenient to install the handle lock 90 on the box door with the fixing plate 98 and the screw 97, and the handle lock 90 is likely to become loose and unstable because the screw 97 is not tightened. In addition, the fixing plate 98 and the screw 97 are usually locked in the middle or the middle lower position of the main body 95 of the lock, so that the upper and lower edges of the handle lock 90 and the box door are likely to be loosened. These problems will all affect whether the locking piece 96 can enter or break away from the locking hole smoothly, in other words, whether these problems are related to whether the box door can be opened or locked smoothly.

The purpose of the present invention is to provide a switch box door handle lock tightening and fixing device, the handle lock is installed on the box door through an elastically deformable buckle ring.

The technical feature of the present invention is a device for tightening and fixing the handle lock of the switch box door. The handle lock is installed in a predetermined opening of the switch box door. On the front side, a lock main body of the handle lock and a lock catch piece pass through the opening and are located on the rear side of the box door; the pressing and fixing device includes: Combined with a buckle ring, the buckle ring includes an open ring-shaped pressing part, the two ends of the pressing part are respectively curved and extended to form an elastic angle, and the open ends of the two elastic angles are respectively extended to form a pivot joint The pins are pivoted in the preset pivot holes on the side of the shell; the pressing part is pushed towards the door, and the buckle ring is turned around with the two pivot pins as the axis until the When the pressing part contacts the box door, the elastic bending angle is compressed and deformed, so that the pressing part generates a spring force to the box door and presses the box door tightly.

Purpose effect of the present invention:

The handle lock is installed on the box door by means of the upper and lower buckle rings, which is fast and easy to install without using hand tools, and the handle lock can be stabilized and secure by the elastic force of the buckle ring Installed on the box door without shaking gap.

In order to illustrate the central idea of the present invention expressed in the column of the above-mentioned summary of the invention, it is expressed in specific embodiments. Various objects in the embodiments are drawn according to proportions, sizes, deformations or displacements suitable for illustration, rather than drawn according to the proportions of actual components, which are described first. And in the following description, the same and symmetrically arranged elements are denoted by the same reference numerals. The directional terms used in the following description are expressed according to the direction of view, and should not be construed as limiting the present invention.

As shown in Fig. 3 to Fig. 5, the handle lock 10 of the present invention is installed in the preset opening of the box door 11, and a frame plate 12 of the handle lock 10 and a switch handle 13 thereof are located on the front face 111 of the box door 11. A lock body 14 of the handle lock 10 and a locking piece 15 pass through the opening and are located on the rear surface 112 of the box door 11 .

The upper and lower parts of the shell 141 of the lock main body 14 are respectively combined with a buckle ring 20, and the buckle ring 20 includes a pressing portion 21 that is an open ring. The open ring includes but is not limited to a circle, an ellipse, Choose one of rectangle, polygon, or geometric shape. Two ends of the pressing portion 21 are respectively extended backward to form an elastic angle 22 , and the open ends of the two elastic angles 22 are respectively extended to form a pivot pin 23 . The pivot pin 23 is pivoted in the predetermined pivot hole 142 on the side of the shell 141 .

As shown in Fig. 6 to Fig. 8, the lock main body 14 of the handle lock 10 and its catch piece 15 are passed through the box door 11 After the predetermined opening, the buckle ring 20 is pivoted in the pivot hole 142 by the two pivot pins 23 . Push the pressing part 21 toward the box door 11, and the buckle ring 20 turns over with the two pivot pins 23 as the axis, until the back ring surface of the pressing part 21 completely touches the box door 11. The slight compression deformation of the elastic corner 22 makes the pressing portion 21 produce a force to press against the door 11 and press the door 11 tightly.

As shown in Figure 7, the technical feature of achieving the slight compression deformation of the elastic bending angle 22 and forcing the pressing part 21 to press the box door 11 is that when the buckle ring 20 and the box door 11 form an angle θ of 40-50 degrees, The outer corner 221 of the elastic corner 22 contacts the box door 11 . Accordingly, when the buckle ring 20 turns over towards the box door 11, the outer corner 221 slides over the box door 11, the elastic corner 22 starts to be compressed, and the buckle ring 20 generates an automatic movement toward the box door. 11 the power of spring pressing, which impels the buckle ring 20 to turn over to the box door 11 automatically until the pressing part 21 presses the box door 11 tightly. Therefore, when the operator operates the buckle ring 20, he only needs to turn the buckle ring 20 over to form an angle θ of 40-50 degrees with the door 11, and then the buckle ring 20 will automatically turn over to the door 11. Press the buckle to install the handle lock 10 on the box door 11. On the contrary, to remove the handle lock 10 , only the buckle ring 20 needs to be reversed to disengage from the box door 11 .

The handle lock 10 is installed on the box door 11 through the buckle ring 20 on the top and bottom, and the handle lock 10 is installed on the box door 11 stably without shaking gap by the elastic force of the buckle ring 20. superior.
