Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, and particularly relates to an assembled distribution box. Background Art

[0002] A distribution box is an electrical equipment, which has the characteristics of small volume, simple installation, special technical performance, fixed position, unique configuration function, not restricted by the site, relatively common application, stable and reliable operation, high space utilization rate, less land occupation and environmental protection effect. Switchgear, measuring instruments, protective electrical appliances and auxiliary equipment are assembled in a closed or semi-closed metal cabinet or on a panel to form a distribution box.

[0003] After retrieval, the patent with the application number CN202311847237.9 discloses a distribution box, which includes a cabinet body, a cabinet door, a motor, a heat dissipation fan, a heat absorption metal plate and a mounting strip. Heat dissipation openings are provided on the opposite side walls of the cabinet body at relative positions, and a plate groove is provided at a position above the heat dissipation opening of the cabinet body. The bottom opening of the plate groove penetrates and is slidably connected with a baffle. The size of the baffle is adapted to the size of the heat dissipation opening. Outer tubes are fixedly connected by embedding on both sides inside the cabinet body near the heat dissipation openings. The top ends of the outer tubes penetrate and are slidably connected with ejector rods. In the distribution box of this invention, by setting a vertically lifting baffle in the heat dissipation opening to adjust the opening size of the heat dissipation opening, there will be no problem of the baffle tilting outwards, and in rainy weather, rainwater will not flow into the interior of the distribution box along the flow, thus ensuring that the distribution box can stably adjust the temperature of the heat dissipation opening while preventing the entry of humid rainwater, ensuring the safety of use and reducing the problem of aging affecting the service life.

[0004] Some current distribution box shells (bottom plate, top plate, two side plates, back plate) are formed by welding. When installing electrical components inside the distribution box, it is not standardized enough. In order to make full use of the space of the distribution box and achieve reasonable installation, electrical components need to be installed inside the distribution box, that is, it is not convenient to pre-assemble the electrical components and their mounting plates, reducing the assembly efficiency of the distribution box; and there are also distribution box shells assembled by bolts, but the currently assembled distribution boxes are not strong enough in stability, especially the connection between two adjacent plates is prone to looseness, reducing the service life of the distribution box. Therefore, we need to propose an assembled distribution box. Content of the Utility Model

[0028] Please refer to Figures 1-10 , the present invention provides a technical solution: an assembled distribution box, including a distribution box housing 1, and the distribution box housing 1 includes a top plate 11, a bottom plate 12, a left side plate 13, a right side plate 14, and a back plate 18 that are stably connected through bolts and a reinforcing structure member 6. For the assembled distribution box, the components can be disassembled and transported during distribution and transportation. Compared with the welded distribution box, the transportation volume is greatly saved, and more distribution boxes can be transported at one time, reducing the transportation cost; the distribution box housing 1 adopts an assembled structure, and it takes only 3 - 4 minutes to complete the assembly of a distribution box housing 1 on average, and the working hours of welding and grinding are reduced by at least 40%, and the electrical complete set working hours are reduced by at least 30%.

[0029] Both the left side plate 13 and the right side plate 14 are prepared by the C-shaped closed bending process, with high strength, and there are zero-ground row installation modular holes on the left side plate 13 and the right side plate 14, saving 20% of the box body use space and meeting the requirements of the left and right door opening directions of the door panel at the same time.

[0030] Moreover, each plate member of the distribution box housing 1 is prepared by a standardized process, and installation holes are reserved on each plate member, which is convenient for later assembly. And the installation plates (such as the switch mounting plate 5 and the two-layer door 4) of electrical components can be provided for users separately in advance, and the control switches and connecting seats are pre-installed, saving the time for customers to assemble the distribution box, and thus improving the assembly efficiency of the distribution box;

[0031] Four reinforcing structure members 6 are used to strengthen the structure of multiple plate members of the assembled distribution box housing 1, ensuring the structural strength and stability of the distribution box housing 1, and thus improving the service life of the distribution box housing 1.

[0032] Inside the distribution box housing 1, two upright columns 8 are installed. Multiple equally spaced reserved mounting holes are provided on the upright columns 8 for facilitating the connection of the switch mounting plate 5. A switch mounting plate 5 for mounting control switches is installed on the two upright columns 8. Inside the distribution box housing 1, two two-layer door modular strips 3 are also installed. A modular two-layer door 4 for shielding components is connected between the two two-layer door modular strips 3. The two-layer door 4 isolates the live parts, but the operating parts of the components are exposed outside the two-layer door 4. One side of the distribution box housing 1 is rotatably installed with a box door 15 through a rotating mechanism 7. A door lock 17 is installed on the box door 15, and a spring plate lock hook 2 corresponding to the position of the door lock 17 is installed on the distribution box housing 1.

[0033] There are four strengthening structural members 6, and the four strengthening structural members 6 are respectively installed at the four corners inside the distribution box housing 1. And the strengthening structural members 6 are installed in a hidden manner, which is more beautiful and does not affect the installation of electrical components.

[0034] As Figure 5 shown, the main structure of the strengthening structural member 6 is set as an L shape. Two first mounting holes 61 for fixing the top plate 11 and the bottom plate 12 and two second mounting holes 62 for fixing the left side plate 13 and the right side plate 14 are respectively opened on the strengthening structural member 6. An integrally formed clamping block 63 is also provided on the strengthening structural member 6.

The rotating mechanism 7 includes a door shaft 71, and the door shaft 71 is made of Q235 round steel - galvanized. A nylon cap 72 is sleeved on the outer wall of the door shaft 71. The rotating mechanism 7 has strong versatility and saves 70% of the assembly man-hours compared with the traditional hinge form.

[0039] A positioning post 73 is connected to the end of the nylon cap 72. A positioning groove is provided on the cabinet door 15. The positioning post 73 is inserted into the inside of the positioning groove. Through the cooperation of the positioning post 73 and the positioning groove, the opening and closing of the cabinet door 15 are realized.

[0040] During use, to improve the assembly efficiency of the distribution box, the electrical components inside it can be pre-assembled. That is, first install the control switch on the switch mounting plate 5, and install the double-layer door 4 on the components to block the components and isolate the live parts. Then assemble the distribution box housing 1 as follows:

[0041] For the convenience of distinction, the four strengthening structural members 6 are respectively denoted as the first member, the second member, the third member, and the fourth member. Use the first member to connect the top plate 11 and the left side plate 13, use the second member to connect the top plate 11 and the right side plate 14, use the third member to connect the left side plate 13 and the bottom plate 12, use the fourth member to connect the right side plate 14 and the bottom plate 12, and then install the back plate 18 on the back of the distribution box housing 1 through bolts;
