Description

Technical Field

[0001] The present invention relates to the field of electrical decoration, and particularly to a bottom box repair device. Background Art

[0002] At present, wall switches and sockets are very important electrical facilities in life. The installation or replacement of switches and sockets both require the use of bottom boxes, and the bottom boxes for installing these switches and sockets are all made of plastic. The plastic structure is prone to damage due to its own characteristics or aging, especially the screw hole parts for fixing the panel. At present, some decoration companies often use inferior bottom boxes or install the bottom boxes obliquely in order to save costs or rush the progress, which are not easy to detect. This makes the subsequent installation of switches or sockets troublesome, with a high installation damage rate and affecting the aesthetics. If the bottom box is replaced, it will inevitably involve damage and repair of the wall, which is not worth the loss. Some existing bottom box repair devices have been widely criticized and have many problems, such as difficult preparation, high cost, few types of bottom boxes that can be adapted, easy damage to the structure, troublesome installation, weak fixing force, and not considering that some bottom boxes with a relatively shallow depth cannot accommodate the repair device. Considering the above situations, the present invention provides a bottom box repair device with simple and fast operation, no damage to the wall, and strong reliability. Summary of the Invention

[0003] The purpose of the present invention is to provide a bottom box repair device to solve the bottom box repair problems mentioned in the above background art and improve the many inconveniences existing in the existing bottom box repair devices.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A bottom box repair device includes a main support rod frame and a movable connection fixing frame. The shape of the main support rod frame is V-shaped, and the overall shape of the combination of the main support rod frame and the movable connection fixing frame is A-shaped. A vertical through hole is opened in the central part of the main support rod frame. Two fixed spikes are provided at the top and bottom of the main support rod frame. The sides of the main support rod frame are all stamped into an incompletely closed eight-shaped cross-section. The movable connection fixing frame is lapped on the sides of the main support rod frame. A vertical through hole is opened in the central part of the movable connection fixing frame. An inclined through hole is opened beside the vertical through hole of the movable connection fixing frame. The sides of the movable connection fixing frame are all stamped into an unclosed U-shaped cross-section. M-shaped triangular grooves are opened at the top and bottom of the movable connection fixing frame, and the M-shaped triangular grooves just fit and connect with the sides of the main support rod frame. A slide rail structure is formed after the eight-shaped cross-section of the main support rod frame is lapped with the M-shaped triangular grooves of the movable connection fixing frame.

[0005] Preferably, a wall switch socket and a wall switch socket bottom box are provided outside the main support bracket and the movable connection fixing bracket. The main support bracket and the movable connection fixing bracket are symmetrically arranged on the left and right sides of the wall switch socket. After using two groups of main support brackets and movable connection fixing brackets to be connected to the wall switch socket by screws to form an integral body and then placing it into the wall switch socket bottom box, the combined body formed by the two groups of main support brackets and movable connection fixing brackets contacts the inner wall top and bottom of the wall switch socket bottom box respectively.

[0006] Preferably, after the screw in the middle of the main support bracket and the movable connection fixing bracket placed in the wall switch socket bottom box is rotated by an external force, the movable connection fixing bracket is pushed forward on the two sides of the main support bracket after the M-shaped triangular groove of the movable connection fixing bracket overlaps with the octagonal cross-section of the main support bracket to form a slide rail structure, and the two fixed spikes at the top and bottom of the main support bracket pierce into the inner wall top and bottom of the wall switch socket bottom box.

[0007] Preferably, the non-isosceles triangle structure formed after the screw passes through the vertical through hole of the main support bracket and is connected to the oblique through hole of the movable connection fixing bracket, and the isosceles triangle structure formed after the screw passes through the vertical through hole of the main support bracket and is connected to the vertical through hole of the movable connection fixing bracket can be used alone or in combination.

[0008] Preferably, both the main support bracket and the movable connection fixing bracket are integral stamping steel frames, and the outer walls of the main support bracket and the movable connection fixing bracket are sprayed with plastic to achieve a certain insulation performance.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention passes a screw through the through-hole of the switch or socket, and then successively passes through the vertical through-hole of the main support rod frame and the vertical through-hole or the adjacent inclined through-hole of the movable connection and fixing frame behind it, and then places the combination formed by the device and the switch or socket into the wall bottom box. By using the pulling force generated by screwing in the screw, the movable connection and fixing frame pushes the main support rod frame to extend, so that the fixed spikes at both ends thereof penetrate into the bottom box, achieving the purpose of fixing the switch or socket. The triangular-like structures in many parts of this device also have many excellent characteristics. First, in terms of stability, the two edges of the main support rod frame of the integral stamping steel frame are wrapped into an approximate triangular body, making it tough and not easily deformed or displaced under force when fixed in the bottom box, ensuring the effectiveness of the device; the M-shaped triangular grooves at the two top ends where the movable connection and fixing frame contacts the main support rod frame ensure that the movable connection and fixing frame moves on the two sides of the main support rod frame, enhancing the overall stability of the device. Secondly, in terms of applicability and flexibility, this device also takes into account the problems of inclined bottom box and partial missing of the bottom box. The triangular structure of this device is easy to vertically adjust the switch and socket. When one side of the screw passes through the through-hole (i.e., the inclined through-hole) at the eccentric position of the movable connection and fixing frame of the device, the non-isosceles triangular structure formed by the two components on this side of the device and the isosceles triangular structure formed by the two components when the screw on the other side passes through the vertical through-hole at the center position of the movable connection and fixing frame of the device are used in combination at the same time. The structures in these two states can cooperate to vertically adjust the position of the screw to a certain extent, so that the positions of the screws on both sides can be adjusted to the same horizontal line when installing the switch and socket, and the switch and socket can be installed neatly and beautifully.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0016] Please refer to Figures 1-4 , the present invention provides a technical solution: a bottom box repair device, including a main body support rod frame 1 and a movable connection fixing frame 2, characterized in that: the shape of the main body support rod frame 1 is V-shaped, and the overall shape of the combination of the main body support rod frame 1 and the movable connection fixing frame 2 is A-shaped. A vertical through hole 3 is opened in the central part of the main body support rod frame 1, and two fixed spikes 4 are provided at the top and bottom of the main body support rod frame 1. The sides of the main body support rod frame 1 are all stamped into an incompletely closed octagonal cross-section 5. The side of the main body support rod frame 1 is overlapped with the movable connection fixing frame 2. A vertical through hole 6 is opened in the central part of the movable connection fixing frame 2, and an inclined through hole 7 is opened beside the vertical through hole 6 of the movable connection fixing frame 2. The sides of the movable connection fixing frame 2 are all stamped into an unclosed U-shaped cross-section 8. M-shaped triangular grooves are opened at the top and bottom of the movable connection fixing frame 2, and the M-shaped triangular grooves just fit with the sides of the main body support rod frame 1. A slide rail structure 9 is formed after the octagonal cross-section 5 of the main body support rod frame 1 is overlapped with the M-shaped triangular groove of the movable connection fixing frame 2.

[0017] Among them, a wall switch socket 10 and a wall switch socket bottom box 11 are provided outside the main body support rod frame 1 and the movable connection fixing frame 2. The main body support rod frame 1 and the movable connection fixing frame 2 are symmetrically arranged on the left and right sides of the wall switch socket 10. After using two groups of the main body support rod frame 1 and the movable connection fixing frame 2 to be connected to the wall switch socket 10 by screws to form an integral body and put it into the wall switch socket bottom box 11, the combined bodies formed by the two groups of the main body support rod frame 1 and the movable connection fixing frame 2 are respectively in contact with the inner wall top and bottom of the wall switch socket bottom box 11.

[0018] According to the ductility characteristics of the metal, two sides of the main support rod frame 1 can be bent outward within a certain range. After the screw between the main support rod frame 1 placed in the wall switch socket bottom box 11 and the movable connection fixing frame 2 is rotated by an external force, the movable connection fixing frame 2 is pushed forward in a slide rail structure 9 formed after the M-shaped triangular groove of the movable connection fixing frame 2 is overlapped with the eight-shaped cross-section 5 of the main support rod frame 1, so that the two sides of the main support rod frame 1 are extended. The two fixing spikes 4 at the top and bottom of the main support rod frame 1 penetrate into the top and bottom inner walls of the wall switch socket bottom box 11.

[0019] In terms of material, both the main support rod frame 1 and the movable connection fixing frame 2 are integral stamping steel frames, and the outer walls of the main support rod frame 1 and the movable connection fixing frame 2 are sprayed with plastic to achieve a certain insulation performance.

[0020] The triangular-like structures in many places of this device have many excellent characteristics. First, in terms of stability, the edges of the two sides of the main support rod frame 1 of the integral stamping steel frame are wrapped into an approximate triangular body, making it tough and not easily deformed and displaced by force when fixed in the bottom box, ensuring the effectiveness of the device; the M-shaped triangular grooves at the two top ends of the movable connection fixing frame 2 in contact with the main support rod frame 1 ensure that the movable connection fixing frame 2 moves on the two sides of the main support rod frame 1, enhancing the overall stability of the device; secondly, in terms of applicability and flexibility, this device also takes into account the problems of the bottom box being tilted and partially missing. The triangular structure of this device is easy to vertically adjust the switch socket. When one side of the screw passes through the inclined through hole 7 at the eccentric position of the movable connection fixing frame 2 of the device, the non-isosceles triangular structure formed by the two components on this side of the device cooperates with the isosceles triangular structure formed by the two components when the screw on the other side passes through the vertical through hole 6 at the central position of the movable connection fixing frame 2 of the device. The two structures in these two states are used in combination at the same time, and the position of the screw can be vertically adjusted to a certain extent, so that the positions of the screws on both sides can be adjusted to the same horizontal straight line when installing the switch socket, and the switch socket can be installed neatly and beautifully.

[0021] A specific application of this embodiment is as follows: First, use two groups of the main support rod frame 1 and the movable connection fixing frame 2 to be connected to the wall switch socket 10 by screws to form an integral body and then place it in the wall switch socket bottom box 11. The combinations formed by the two groups of the main support rod frame 1 and the movable connection fixing frame 2 are respectively in contact with the top and bottom inner walls of the wall switch socket bottom box 11. Then, the screw between the main support rod frame 1 and the movable connection fixing frame 2 is rotated by an external force, so that the movable connection fixing frame 2 is pushed forward in a slide rail structure 9 formed after the M-shaped triangular groove of the movable connection fixing frame 2 is overlapped with the eight-shaped cross-section 5 of the main support rod frame 1, so that the two sides of the main support rod frame 1 are extended. The two fixing spikes 4 at the top and bottom of the main support rod frame 1 penetrate into the top and bottom inner walls of the wall switch socket bottom box 11.
