Description

Technical Field

[0001] This utility model belongs to the field of steel cabinet processing technology, specifically relating to a steel cabinet body connected by mortise and tenon joints. Background Technology

[0002] Currently, all components of steel cabinets are connected by welding. However, some cabinets, such as mobile phone storage cabinets and multi-door shoe cabinets, are more complex. Because the interior of these steel cabinets is divided into multiple rectangular storage spaces with front openings by multiple vertically distributed horizontal and vertical partitions, using traditional processing methods would increase the number of product components, create a cluttered work site, and increase the amount of welding work. Utility Model Content

[0003] This utility model addresses the shortcomings of the prior art by providing a steel cabinet with mortise and tenon joints. By using integrated horizontal and vertical partitions connected by mortise and tenon joints, the number of parts can be effectively reduced, the workshop environment can be improved, the workload of welding workpieces can be reduced, production efficiency can be increased, and welding costs can be reduced.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A steel cabinet with mortise and tenon joints includes a cabinet frame, at least one vertical partition, and multiple horizontal partitions. The at least one vertical partition is vertically connected to the multiple horizontal partitions, dividing the interior of the cabinet frame into multiple accommodating spaces. The rear end of the vertical partition is provided with multiple first splicing grooves spaced apart from top to bottom. The multiple horizontal partitions are distributed parallelly from top to bottom. The front end of each horizontal partition is provided with a second splicing groove. The first splicing grooves and the second splicing grooves are connected to form a cross mortise and tenon structure.

[0006] Preferably, the length of the first splicing groove is half the front and rear width of the vertical partition, and the length of the second splicing groove is half the front and rear width of the horizontal partition.

[0007] Preferably, the number of vertical partitions is two or more, and the two or more vertical partitions are distributed in parallel with intervals from left to right.

[0008] Preferably, the cabinet frame is a hollow cuboid structure with an open front end, formed by connecting a top plate, a bottom plate, a back plate, and two side plates.

[0009] Preferably, the upper end, lower end and rear end of the vertical partition are bent at 90° to form a first vertical folded edge, and a first positioning hole is provided on the first vertical folded edge. The top plate, bottom plate and back plate are provided with first mating holes that match the number and position of the first positioning holes.

[0010] Preferably, the rear end of the partition plate is bent at 90° to form a first horizontal folded edge, and a second positioning hole is provided on the first horizontal folded edge. A second mating hole is provided on the back plate that matches the number and position of the second positioning hole.

[0011] Preferably, the front end of the vertical partition and the side panel is provided with a second vertical folded edge formed by bending, and the lower front end of the horizontal partition and the top panel is provided with a second horizontal folded edge formed by bending. The second vertical folded edge and the second horizontal folded edge are provided with mounting holes for installing cabinet doors.

[0012] Preferably, the second vertical folded edge is provided with a first limiting groove that cooperates and connects with the second horizontal folded edge, and the second horizontal folded edge is provided with a second limiting groove that cooperates and connects with the second vertical folded edge.

[0013] Preferably, the second vertical folded edge is provided with positioning protrusions at both the top and bottom ends, and the positioning protrusions are connected to the positioning grooves provided on the second horizontal folded edge at the lower front end of the top plate or on the bottom plate.

[0014] Preferably, the base plate has supporting flanges formed by downward bending on both the front and rear sides, and a cavity is formed between the two supporting flanges.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this invention, the vertical partitions used in each column of accommodating space are a single integrated structure from top to bottom, and the horizontal partitions used in each layer of accommodating space are also a single integrated structure from left to right. In contrast, the vertical and horizontal partitions required for each layer of accommodating space in traditional steel cabinets are all independent thin plates, and welding is required between each pair of adjacent independent thin plates. Based on this, the vertical and horizontal partitions of this invention are connected by a cross tenon and mortise structure, which has high connection strength, effectively reduces the number of workpieces for horizontal and vertical partitions, improves the workshop environment, reduces the amount of welding work between workpieces, improves production efficiency, and reduces welding costs.

[0030] 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.

[0031] In the description of this utility model, it should be understood that the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] like Figures 1 to 3 As shown, a steel cabinet connected by mortise and tenon joints includes a cabinet frame 1, at least one vertical partition 2, and multiple horizontal partitions 3. The at least one vertical partition is perpendicularly connected to the multiple horizontal partitions, dividing the interior of the cabinet frame into multiple accommodating spaces. The rear end of each vertical partition has multiple first splicing grooves 201 spaced apart from top to bottom. The multiple horizontal partitions are arranged parallel to each other from top to bottom, and the front end of each horizontal partition has a second splicing groove 301. The first splicing grooves and second splicing grooves mate to form a cross-shaped mortise and tenon structure. There are two or more vertical partitions, arranged parallel to each other from left to right. In this embodiment, there are two vertical partitions and ten horizontal partitions. The vertical and horizontal partitions mate to divide the interior of the cabinet frame into 33 accommodating spaces of the same size. In this invention, the vertical partitions used in each column of accommodating space are an integral structure from top to bottom, and the horizontal partitions used in each layer of accommodating space are also an integral structure from left to right. In contrast, the vertical and horizontal partitions required for each layer of accommodating space in traditional steel cabinets are independent thin plates. Based on this, this invention effectively reduces the number of workpieces for horizontal and vertical partitions, improves the workshop environment, reduces the workload of workpiece welding, improves production efficiency, and reduces welding costs. Moreover, in this invention, the first splicing groove on the vertical partition and the first splicing groove on the horizontal partition cooperate and nest with each other to form a cross tenon and mortise structure, which can achieve a firm connection between the vertical and horizontal partitions and has high connection strength. When subjected to external force, this connection structure can disperse stress through the interlocking effect of the two and maintain the stability of the structure.

[0034] like Figures 3 to 7 As shown, the length of the first splicing groove is half the front and rear width of the vertical partition, and the length of the second splicing groove is half the front and rear width of the horizontal partition. The width of the vertical partition is the same as the width of the horizontal partition, thus ensuring that the front and rear end faces of the vertical and horizontal partitions are on the same vertical plane after splicing. During assembly, the first splicing groove on the vertical partition and the second splicing groove on the corresponding horizontal partition are aligned on the same straight line. The vertical partition is then moved backward to achieve a cross-shaped connection with the horizontal partition. To further enhance the connection strength and stability, spot welding can be performed at the corners where the two parts connect.

[0035] like Figures 1 to 3As shown, the cabinet frame is a hollow cuboid structure with an open front end, formed by connecting a top plate 101, a bottom plate 102, a back plate 103, and two side plates 104. In actual production, to facilitate painting after welding, spray hook holes 18 are provided at the rear corners of the top plate and side plates. Combined with... Figure 7 As shown, the upper, lower, and rear ends of the vertical partition are bent at 90° to form a first vertical folded edge 4. A first positioning hole 5 is provided on the first vertical folded edge. Figure 8 , Figure 9 and Figure 10 As shown, the top plate, bottom plate, and back plate are provided with first mating holes 6, the number and position of which match the first positioning holes. Combined with... Figure 6 As shown, the rear end of the horizontal partition is bent at 90° to form a first horizontal folded edge 7. A second positioning hole 8 is provided on the first horizontal folded edge. A second mating hole 9 matching the number and position of the second positioning hole is provided on the back plate. The first positioning hole and the first mating hole have the same shape and size, and the second positioning hole and the second mating hole have the same shape and size, which facilitates accurate positioning during assembly. After precise positioning, each positioning hole and mating hole is filled and welded, thereby stably connecting the vertical partition, the horizontal partition and the various components of the cabinet frame.

[0036] like Figure 7 and Figure 11 As shown, the front end of the vertical partition and side panel is provided with a second vertical folded edge 10 formed by bending, as shown. Figure 5 and Figure 8 As shown, the lower front end of the partition and the top plate is provided with a second horizontal folded edge 11 formed by bending. The second vertical folded edge and the second horizontal folded edge are provided with mounting holes 12 for installing cabinet doors. The partition and the bottom plate are also provided with mounting holes at corresponding positions. The mounting holes are located on the same central axis as the mounting holes on the second horizontal folded edge of the partition. The mounting holes on the second vertical folded edge are used to install the magnetic attraction of the cabinet door. The mounting holes on the second horizontal folded edge, the partition, and the bottom plate are used to install the hinge of the cabinet door. The upper end of the hinge is installed in the mounting hole 12 on the second horizontal folded edge at the bottom of the top plate or the partition, while the lower end of the hinge is installed in the mounting hole 12 on the partition or the bottom plate. The hinge and magnetic attraction structure of the cabinet door are existing technologies and will not be described in detail here.

[0037] like Figures 4 to 7 As shown, in order to avoid the second vertical fold and the second horizontal fold affecting the connection between the vertical partition and the horizontal partition, a first limiting groove 13 is provided on the second vertical fold to cooperate with and connect with the second horizontal fold, and a second limiting groove 14 is provided on the second horizontal fold to cooperate with and connect with the second vertical fold. While achieving mutual fitting, the first limiting groove can also effectively support and fix the horizontal partition, while the second limiting groove can effectively limit and fix the vertical partition.

[0038] like Figure 4 , Figure 7 , Figure 8 and Figure 9 As shown, the top and bottom of the second vertical folded edge are provided with positioning protrusions 15. The positioning protrusions are connected to the positioning grooves 16 on the second horizontal folded edge at the lower front end of the top plate or on the bottom plate, which facilitates accurate positioning during assembly. The front and rear sides of the bottom plate are provided with supporting folded edges 17 formed by bending downwards (two 90° bends). A cavity is formed between the two supporting folded edges to prevent the bottom plate from directly contacting the ground. It can also be used to install support legs, which will not be described in detail here.
