The main function of the distribution box is to distribute the electric energy from the power source to different circuits so as to meet the requirements of various devices and electricity in the building. It may also provide circuit protection, such as short-circuit protection, overload protection, and ground protection, to ensure safe and reliable operation of the circuit and electrical equipment.

In designing and installing the distribution box, it is necessary to select appropriate circuit protectors and electrical equipment according to factors such as the electrical loads of the building, the characteristics of the electrical equipment, and the power requirements, and to ensure compliance with local electrical safety regulations and standards. In addition, it is also very important to periodically check and maintain the distribution box to ensure its normal operation and to avoid the occurrence of electrical safety accidents.

The prior distribution box is provided with mounting plates on two sides of a clamping groove guide rail, first bolt holes are formed in the side walls of the top of the distribution box at intervals, a user firstly clamps the electric components on the clamping groove guide rail, then the clamping groove guide rail is arranged in the distribution box until the mounting plates are abutted against the side walls of the top of the distribution box, finally the user passes through the mounting plates to be locked in the corresponding first bolt holes, the clamping groove guide rail cannot be adjusted in height, a plurality of bolts are needed to be used for locking the mounting plates, the bolts are difficult to align, the distribution box is time-consuming and long in installation, and the installation is complicated.

Disclosure of Invention

The invention aims to provide a distribution box with easily-installed and easily-detached clamping groove guide rails and firmly-locked clamping groove guide rails.

The purpose of the invention is realized in the following way:

the distribution box comprises a box body, a clamping groove guide rail and a locking device, wherein the clamping groove guide rail is used for installing electric components, guide notches are formed in opposite side walls of an inner cavity of the box body, the lower ends of the guide notches are higher than the bottom wall of the box body, and a clamping opening is formed between the lower ends of the guide notches and the bottom wall of the box body;

the locking device comprises a sliding block, the sliding block is provided with a sliding channel, the clamping groove guide rail penetrates through the sliding channel, the sliding block is sleeved on the clamping groove guide rail, and the sliding block can slide along the length direction of the clamping groove guide rail;

Further, the sliding block is a flexible plastic sliding block. The sliding block is a flexible plastic sliding block, so that the sliding block has elasticity, and when the sliding block moves to the guiding notch, the elastic force pushes the clamping hook to be always inserted into the clamping notch, and the clamping groove guide rail is maintained to be locked.

Further, the side wall of the box body is provided with a first baffle and a second baffle, the first baffle and the second baffle enclose a guide notch, the lower end of the box body, which is positioned at the guide notch, is provided with a bottom plate for supporting a clamping groove guide rail, the bottom plate is provided with a third bolt hole, a gap between the first baffle and the bottom plate forms the clamping opening, and a gap between the second baffle and the bottom plate forms the clamping opening.

Firstly, a user installs an electric component in a clamping groove guide rail, then respectively aligns the sliding blocks to corresponding guide notches, then presses down the clamping groove guide rail, and because the sliding blocks have elasticity, the sliding blocks deform to enter the guide notches until the bottoms of the sliding blocks touch the bottom plate, and meanwhile, the clamping hooks are inserted into the clamping openings to finish clamping of the clamping groove guide rail, and the clamping groove guide rail is arranged in a box body and clamped to finish first locking.

Then, the user passes the bolt and locks on the third bolt hole through first bolt hole, second bolt hole, draw-in groove guide rail and bottom plate are connected to lock the draw-in groove guide rail, accomplish the second and lock.

Because the slider is flexible plastic slider, if the user need finely tune draw-in groove guide rail height, the user screws the bolt to adjust the height of draw-in groove guide rail, and the bolt screwing process moreover, the protruding further chucking of slider is corresponding first separation blade lower extreme or second separation blade lower extreme, makes the locking of draw-in groove guide rail more firm.

Further, the clamping hooks respectively lean against the lower ends of the corresponding first blocking pieces or the lower ends of the second blocking pieces, so that the clamping hooks are locked at the clamping openings.

The beneficial effects of the invention are as follows:

according to the invention, when the clamping groove guide rail is installed, a user installs an electric component in the clamping groove guide rail, then aligns the sliding blocks with the corresponding guide slots respectively, then presses down the clamping groove guide rail, the sliding blocks enter the guide slots until the clamping hooks are inserted into the clamping openings, the clamping groove guide rail is arranged in the box body and clamped, the clamping groove guide rail is simple to install, when the clamping groove guide rail is disassembled, the user lifts the clamping groove guide rail, the sliding blocks slide out along the guide slots, so that the clamping hooks leave the clamping openings, the first locking state is released, the clamping groove guide rail is taken out, the installation or the disassembly of subsequent electric appliance components is facilitated, and the operation is very simple.

According to the invention, a user installs an electric component in the clamping groove guide rail, then respectively aligns the sliding blocks to the corresponding guide slots, then presses down the clamping groove guide rail, and because the sliding blocks have elasticity, the sliding blocks deform to enter the guide slots until the bottoms of the sliding blocks touch the bottom plate, and meanwhile, the clamping hooks are inserted into the clamping openings to finish clamping of the clamping groove guide rail, and the clamping groove guide rail is placed in the box body and clamped to finish first locking.

According to the invention, a user passes through the first bolt hole and the second bolt hole to lock the bolt on the third bolt hole, and the clamping groove guide rail is connected with the bottom plate, so that the clamping groove guide rail is locked, and the second locking is completed.

According to the invention, as the sliding block is a flexible plastic sliding block, if a user needs to finely adjust the height of the clamping groove guide rail, the user screws the bolt so as to adjust the height of the clamping groove guide rail, and in the screwing process of the bolt, the protrusions of the sliding block further clamp the lower ends of the corresponding first blocking pieces or the lower ends of the second blocking pieces, so that the clamping groove guide rail is more firmly locked.

According to the invention, a user unscrews the bolt until the bolt leaves the third bolt hole and the second bolt hole, the clamping groove guide rail is separated from the bottom plate, so that the second locking state is released, then the user lifts the clamping groove guide rail, the sliding block deforms and slides out along the guide notch due to elasticity of the sliding block, so that the clamping hook leaves the clamping opening, the first locking state is released, the installation or the disassembly of subsequent electrical parts is facilitated, and the operation is very simple.
