Technical Field

[0001] The utility model relates to a cabinet, in particular to a combined plastic cabinet. Background Art

[0002] Traditional cabinets are generally of an integral structure, which is inconvenient to manufacture, difficult to meet diverse requirements, and cannot be disassembled and assembled, bringing great inconvenience to transportation work.

[0003] Furthermore, to solve the deficiencies of traditional integral-structure cabinets, combined cabinets have emerged. Combined cabinets can not only be combined as needed to meet diverse requirements, but also can be disassembled and assembled as needed for convenient transportation. However, the combined cabinets on the market often have inconvenient assembly, low assembly efficiency, affecting the production efficiency of combined cabinets and the user experience during user assembly. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a combined plastic cabinet that can adjust the height of the cabinet body as needed to meet diverse requirements, is convenient to assemble, has high assembly efficiency, and can reduce production costs.

[0005] The technical solution of the utility model is as follows:

[0006] A combined plastic cabinet, comprising:

[0007] A cabinet body, including a plurality of cabinet monomers distributed successively from top to bottom. Any two adjacent cabinet monomers are connected by a buckle. Each cabinet monomer is surrounded by a rear side wall and left and right side walls. The upper and lower ends of the cabinet body are open, and the front side of the cabinet body is open;

[0008] Upper and lower end covers, covering the upper and lower openings of the cabinet body. The cabinet body and the end covers are connected by a buckle;

[0009] One or more cabinet doors distributed successively from top to bottom. The cabinet doors are hinged to the cabinet body through hinges to cover the front opening of the cabinet body. In the combined plastic cabinet of this solution, the cabinet body includes cabinet monomers distributed successively from top to bottom, and any two adjacent cabinet monomers are connected by a buckle. Thus, the number of cabinet monomers can be selected as needed to adjust the height of the cabinet body to meet diverse requirements. Since the cabinet monomers are connected by a buckle and the cabinet body and the end covers are connected by a buckle, the cabinet monomers can be assembled into the cabinet body conveniently and quickly, and then the upper and lower end covers can be assembled to the cabinet body conveniently and quickly. Then, the cabinet doors are installed. Its assembly is convenient, the assembly efficiency is high, the production efficiency of the combined cabinet can be improved, and the user experience during user assembly can be improved.

[0010] In addition, since the cabinet body is composed of several cabinet units, on the one hand, the production mold of the cabinet units can be effectively reduced, thereby reducing the production cost; on the other hand, the cabinet body is modularly produced, and the number of cabinet units can be selected according to needs, so as to adjust the height of the cabinet body to meet diverse requirements. There is no need to make a mold for each cabinet body with different height specifications, which can effectively reduce the number of molds and thus reduce the production cost.

[0011] Preferably, it further includes two fixed side frames on the left and right, which are correspondingly arranged on the left and right sides of the front opening of the cabinet body. The left and right side walls of each cabinet unit are connected to the corresponding fixed side frames through a mortise and tenon structure, and the cabinet door is hinged to one of the fixed side frames through a hinge. In this way, each cabinet unit can be more reliably connected into a whole through the two fixed side frames on the left and right, improving the structural stability of the cabinet body. On the other hand, the left and right side walls of each cabinet unit are connected to the corresponding fixed side frames through a mortise and tenon structure, which facilitates the assembly of the fixed side frames.

The mortise is communicated with the vertical channel, and a metal rod is embedded in the vertical channel and presses tightly on the tenon. In this way, on the one hand, the structural stability of the cabinet body can be further improved through the metal rod embedded in the vertical channel; on the other hand, since the metal rod presses tightly on the tenon, it can also ensure the tight fit between the tenon and the mortise of the mortise and tenon structure, avoiding the loosening of the fixed side frame and further improving the structural stability of the cabinet body.

[0013] Preferably, the fixed side frame is composed of several border segments distributed in sequence from top to bottom. Each border segment is provided with the above-mentioned mortise, and the length of each border segment is an integer multiple of the height of the cabinet unit. Since the length of each border segment is an integer multiple of the height of the cabinet unit, the length of the fixed side frame can be matched and adjusted according to the number of different cabinet units to meet diverse requirements.

[0014] Preferably, the fixed side frame is a plastic side frame. The plastic side frame is not only convenient for actual processing and production, but also has good rust and corrosion resistance.

[0015] Preferably, the rear side wall and the left and right side walls of the cabinet unit are both hollow structures, and the buckles between the cabinet units are accommodated in the hollow structures. In this way, on the one hand, the production materials of the cabinet units can be effectively reduced; on the other hand, the weight of the cabinet units can be effectively reduced.

[0016] Preferably, a positioning structure is provided between any two adjacent cabinet units. The positioning structure includes a positioning groove and a positioning protrusion that cooperates with the positioning groove. One of the positioning groove and the positioning protrusion is provided on the top surface of the cabinet unit, and the other is provided on the bottom surface of the cabinet unit. In this way, the positioning between any two adjacent cabinet units can be ensured to be accurate, and thus the assembly quality of the cabinet body can be guaranteed.

[0017] Preferably, an end cover groove is provided on the end cover. The rear side wall and the left and right side walls of a cabinet unit adjacent to the end cover are inserted into the end cover groove. In this way, the structural stability between the end cover and the cabinet body can be ensured by the cooperation of the end cover groove and the cabinet unit.

[0018] Preferably, the rear side walls of any two adjacent cabinet units are connected by the snap fasteners, and the left and right side walls of any two adjacent cabinet units are also respectively connected by the snap fasteners. In this way, the connection structural stability between any two adjacent cabinet units can be ensured.

[0019] Preferably, the cabinet body and the upper and lower end covers are both made of plastic. The cabinet body and the upper and lower end covers made of plastic are not only convenient for actual processing and manufacturing, but also have good rust and corrosion resistance.

[0020] The beneficial effects of the present utility model are as follows:

[0021] First, the number of cabinet units can be selected according to needs, so as to adjust the height of the cabinet body to meet diverse requirements.

[0022] Second, it is convenient to assemble, has a high assembly efficiency, can improve the production efficiency of the combined cabinet and the user experience during user assembly.
