Description

Technical Field

[0001] This utility model relates to the field of switch boxes, and in particular to a fastening type low-voltage switch box. Background Technology

[0002] In power systems, low-voltage switch boxes are important power distribution and control equipment, widely used in various construction sites, industrial plants and commercial venues. They undertake the key tasks of distributing electrical energy, controlling the switching on and off of circuits, and protecting electrical lines and equipment from damage caused by overloads, short circuits and other faults.

[0003] Traditional low-voltage switch boxes are mostly installed in specific locations using bolts or welding. These installation methods not only require specialized tools and high operational skills, but also easily damage the switch box itself or the mounting foundation during installation. Furthermore, once installed, repositioning or disassembly is difficult, hindering flexible deployment and maintenance of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a fastening-type low-voltage switch box, which solves the problem of cumbersome installation and fixing of existing low-voltage switch boxes.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A fastening type low-voltage switch box includes a box body, with symmetrical sliding holes on the back side of the box body. A slider is slidably connected inside the sliding holes. A threaded rod is rotatably connected inside the box body. An adjusting plate is threadedly connected to the outside of the threaded rod. Connecting rods are rotatably connected to both sides of the adjusting plate. The other end of the connecting rod is rotatably connected to the corresponding slider. A movable clamping block is symmetrically provided on the back side of the box body. The slider is fixedly connected to the corresponding movable clamping block. A fixed clamping block is symmetrically fixedly connected on the back side of the box body. A groove is provided on the side of the fixed clamping block opposite to the movable clamping block.

[0006] Preferably, the bottom of the enclosure is provided with equally spaced wiring holes for connecting external lines to the electrical components inside the low-voltage switch box.

[0007] Preferably, each wiring hole is fitted with a rubber plug that slides inside. The rubber plug is used to seal the wiring hole when it is not in use, preventing dust, moisture, etc. from entering the box.

[0008] Preferably, support feet are fixedly connected to the four corners of the bottom of the box. The support feet are used to provide stable support when the low-voltage switch box is placed on a flat surface, and to create a gap between the bottom of the box and the placement surface.

[0009] Preferably, a handle is rotatably connected to the top of the box, which is used to facilitate carrying or moving the low-voltage switch box.

[0010] Preferably, mounting brackets are fixedly connected at equal intervals inside the enclosure. The mounting brackets are used to install and fix the electrical components inside the low-voltage switch box.

[0011] Preferably, a knob is fixedly connected to one end of the threaded rod. The knob is used to facilitate the operator to rotate the threaded rod to control the axial movement of the adjusting plate.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. This utility model utilizes the coordinated action of components such as a moving clamping block, a fixed clamping block, a threaded rod, an adjusting plate, a connecting rod, and a slider. By simply rotating the knob at one end of the threaded rod, the adjusting plate can be moved axially along the threaded rod. This, in turn, drives the slider to slide along the sliding hole via the connecting rod, enabling the moving clamping block and the fixed clamping block to move closer to or separate from each other. This allows the low-voltage switch box to be quickly and conveniently clamped onto steel columns or other components on construction sites, improving installation efficiency and reducing installation difficulty.

[0014] 2. This utility model uses a rubber plug to effectively seal the wiring hole when it is not in use, preventing external impurities such as dust and moisture from entering the box, thereby protecting the electrical components inside the box from damage and extending the service life of the switch box.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4This embodiment provides a fastening type low-voltage switch box, including a box body 1. The back side of the box body 1 is symmetrically provided with sliding holes 2. A slider 3 is slidably connected inside the sliding holes 2. A threaded rod 4 is rotatably connected inside the box body 1. An adjusting plate 5 is threadedly connected to the outside of the threaded rod 4. Connecting rods 6 are rotatably connected to both sides of the adjusting plate 5. The other end of the connecting rod 6 is rotatably connected to the corresponding slider 3. A movable clamping block 7 is symmetrically provided on the back side of the box body 1. The slider 3 is fixedly connected to the corresponding movable clamping block 7. A fixed clamping block 8 is symmetrically fixedly connected on the back side of the box body 1. A groove 9 is provided on the side of the fixed clamping block 8 opposite to the movable clamping block 7.

[0022] When the threaded rod 4 is rotated, the rotation of the threaded rod 4 is converted into the linear movement of the adjusting plate 5 along the axial direction of the threaded rod 4. When the adjusting plate 5 moves, it will pull or push the connecting rods 6 on both sides. The connecting rods 6 will then drive the slider 3 to slide along the sliding hole 2, so that the moving clamp 7 moves together with the slider 3, so that the moving clamp 7 and the fixed clamp 8 can move closer or separate. When the moving clamp 7 and the fixed clamp 8 are close together, they can be clamped on the steel column or other components on the construction site to complete the installation and fixation of the low-voltage switch box. When disassembly is required, the threaded rod 4 is rotated in the opposite direction to separate the moving clamp 7 and the fixed clamp 8.

[0023] Wiring holes 10 are provided at equal intervals at the bottom of the enclosure 1. During installation and use, external power lines, control lines and other lines can be introduced into the enclosure 1 through these wiring holes 10 to connect with internal electrical components such as circuit breakers and contactors to realize power transmission and control functions.

[0024] Each wiring hole 10 has a rubber plug 11 that is slidably inserted inside. Due to the good elasticity and sealing properties of rubber, the rubber plug 11 can fit tightly against the inner wall of the wiring hole 10, preventing external impurities such as dust and moisture from entering the box 1. When the wiring hole 10 needs to be used, simply pull the rubber plug 11 out of the wiring hole 10.

[0025] Support feet 12 are fixedly connected to the four corners of the bottom of the enclosure 1. The presence of support feet 12 creates a certain gap between the bottom of the enclosure 1 and the placement surface. This gap facilitates air circulation inside the enclosure 1, thereby improving heat dissipation efficiency. It also facilitates wiring at the bottom of the enclosure 1 and prevents the bottom of the enclosure 1 from directly contacting the damp ground, reducing the corrosion of the enclosure 1 by ground moisture.

[0026] A handle 13 is rotatably connected to the top of the box 1. When the switch box needs to be moved, the operator can hold the handle 13 to lift or carry the switch box to a designated location. When the handle 13 is not in use, it can also be rotated to a suitable position for storage, so as to avoid the handle 13 protruding and affecting the placement and overall appearance of the switch box.

[0027] The enclosure 1 is fixedly connected with mounting brackets 14 at equal intervals. The mounting brackets 14 provide installation positions for the electrical components inside the low-voltage switch box. The electrical components can be fixed to the mounting brackets 14 by screws, clips, etc.

[0028] A knob 15 is fixedly connected to one end of the threaded rod 4. The knob 15 provides the operator with a convenient point of leverage for rotating the threaded rod 4. When it is necessary to adjust the distance between the moving clamp 7 and the fixed clamp 8, the operator only needs to hold the knob 15 and turn it to drive the threaded rod 4 to rotate.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
