Description

Technical Field

[0001] This utility model relates to the field of mechanical structure technology, and in particular to a housing for a sheet metal controller. Background Technology

[0002] Traditional sheet metal controller housings typically use screws to fix the upper and lower housings together. This installation method requires tools such as screwdrivers, is cumbersome, has low installation efficiency, and consumes a lot of manpower and time. On the other hand, repeated disassembly and reassembly of screws can easily lead to problems such as stripped screw holes, affecting the lifespan and structural stability of the controller. Utility Model Content

[0003] The technical solution of this utility model to solve the above-mentioned technical problems is to provide a housing for a sheet metal controller, including: an upper housing and a lower housing. An elastic buckle is provided on one side of the upper housing, and multiple limiting structures are provided on the two adjacent sides. A limiting hole for connecting with the elastic buckle is provided on one side of the lower housing, and a sliding groove for connecting the limiting structure is provided on the two adjacent sides.

[0004] Furthermore, the elastic buckle includes a base and an arc-shaped protrusion. The base is fixed to the upper housing, and one end of the arc-shaped protrusion is connected to the base, while the other end protrudes from the base.

[0005] Furthermore, the housing for the sheet metal controller also includes a PCBA board, which is fixed to the lower housing by screws.

[0006] Furthermore, the limiting structure and the upper housing form a limiting groove for engaging with the groove wall forming the sliding groove.

[0007] The technical solution of this utility model uses a two-sided mounting structure for quick positioning, and uses elastic buckles and the limiting of the two-sided structure after sliding for fixed installation. This is faster and more efficient, while also ensuring the reliability of the controller installation and improving the aesthetics of the controller. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0017] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "several" or "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0020] This utility model proposes a housing for sheet metal controllers, aiming to design a housing that is more efficient and convenient in the installation process while ensuring reliable and stable installation.

[0021] The specific structure of the housing for the sheet metal controller proposed in this utility model will be described below in specific embodiments:

[0022] In the technical solution of this embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a housing for a sheet metal controller includes an upper housing 10 and a lower housing 20. One side of the upper housing 10 is provided with an elastic buckle 11, and the two adjacent sides are provided with a plurality of limiting structures 12. One side of the lower housing 20 is provided with a limiting hole 21 for connecting with the elastic buckle 11, and the two adjacent sides are provided with a sliding groove 22 for connecting the limiting structure 12.

[0023] Furthermore, the elastic buckle 11 includes a base 111 and an arc-shaped protrusion 112. The base 111 is fixed on the upper housing 10, and one end of the arc-shaped protrusion 112 is connected to the base 111, while the other end protrudes from the base 111.

[0024] Furthermore, the housing for the sheet metal controller also includes a PCBA board 30, which is fixed to the lower housing 20 by screws.

[0025] Furthermore, the limiting structure 12 and the upper housing 10 form a limiting groove for engaging with the groove wall forming the sliding groove 22.

[0026] Working principle: During installation, the PCBA board 30 is first fixed to the lower housing 20. Then, the limiting structures 12 on both sides of the upper housing 10 are aligned and inserted into the sliding grooves 22 on both sides of the lower housing 20 to achieve quick positioning during installation. The upper and lower housings 20 are pressed tightly, causing the elastic buckle 11 of the upper housing 10 to deform and engage in the limiting hole 21. At the same time, the limiting groove of the limiting structure 12 engages in the groove wall of the sliding groove, completing the fit and achieving limiting in the upper and lower directions. Through this double locking mechanism, the upper and lower housings 20 are limited and fixed, completing the installation.

[0027] The housing used for sheet metal controllers can improve installation efficiency and reduce labor costs. It achieves rapid installation through three actions: insertion, pressing, and pushing. This makes the installation process more convenient and faster while ensuring installation reliability. It is suitable for sheet metal structural parts that have high requirements for assembly efficiency, structural aesthetics, and ease of disassembly and assembly.

[0028] The screwless sliding installation method for the shell of a sheet metal controller in this application significantly improves installation efficiency and reduces labor costs. It utilizes the mounting structures on both sides for quick positioning, and employs elastic clips 11 and the limiting mechanisms on both sides after sliding for secure installation. This method is faster and more efficient while ensuring the reliability of the controller installation and enhancing its aesthetics. The above are merely implementation examples of this application and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
