Description

Technical Field

[0001] This utility model relates to the field of power instrument technology, specifically a novel instrument installation structure. Background Technology

[0002] Electrical instruments typically have a manually operable main body. For convenience, they are usually installed in the most easily accessible location within the electrical box. Currently, to balance safety and ease of operation, they are often installed on the cabinet door. For example, many distribution cabinet doors have openings for easy observation and operation, but this leaves an open space, which can affect dust prevention. Currently, there are methods to overcome these problems by directly mounting the panel onto the cabinet door. However, this requires screws and other fasteners for fixation, and since cabinets are generally made of metal, the installation process is quite cumbersome. Therefore, a novel instrument installation structure is proposed. Utility Model Content

[0023] 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.

[0024] Please see Figure 1-8 This utility model provides a technical solution: a novel instrument mounting structure, including a housing 1 and a display panel 2. The display panel 2 is mounted on the front end face of the housing 1 and is used to mount panel components. The size of the main body of the housing 1 matches the opening size of the external cabinet panel 4, such as... Figure 2 The outer casing 1 shown is also provided with heat dissipation vents (heat dissipation slots). The cabinet panel 4 can be the cabinet door of the power distribution cabinet or other applicable cabinet doors (no restrictions are made here, and any applicable form in the relevant field is applicable). In actual applications, the openings of the cabinet panel 4 are prefabricated and generally have corresponding standards, so the opening error is generally not too large.

[0025] The outer casing 1 has an outwardly folded edge 101 around its perimeter, i.e. Figure 3 The outward folding structure shown here has a folded edge 101 larger than the opening size of the cabinet panel 4, and the main body of the outer shell 1 is smaller than the opening size of the cabinet panel 4. This allows the outer shell 1 to be inserted inward from one side of the cabinet panel 4, with the folded edge 101 fitting into the opening of the cabinet panel 4 (as shown). Figure 4 The outer casing 1 has a mounting faceplate 3 on at least one side. When the outer casing 1 is placed on the cabinet panel 4, the folded edge 101 and the mounting faceplate 3 are located on both sides of the cabinet panel 4 and are in contact with the cabinet panel 4 (e.g., Figure 5 );

[0026] like Figure 3As shown, in order to improve installation stability and balance, there are two mounting faceplates 3, which are placed symmetrically on both sides of the outer shell 1 (of course, three or four can also be set according to the actual situation). The mounting faceplates 3 are provided with buffer clips 5 at the contact positions with the cabinet panel 4. Due to manufacturing reasons, there may be errors, so buffer clips 5 are set to improve the clamping stability.

[0027] Specifically, the buffer clip 5 includes two symmetrical curved rings 501, each with a protrusion 502, and the two curved rings 501 are connected by a reinforcing rib 503. The protrusion 502 is used to contact the cabinet panel 4. Both the buffer clip 5 and the mounting clip 3 are made of engineering plastic, which has a certain degree of deformability (metal materials can also be used, but considering the conductivity issue, insulating engineering plastics are generally used). The elliptical curved ring 501 structure can maintain a certain preload by deforming the curved ring 501. At the same time, when there is a certain dimensional error, the deformation of the curved ring 501 can also ensure the reliability of the installation.

[0028] Specifically, the mounting faceplate 3 is snapped into the side wall of the outer casing 1. As in the case described above, the mounting faceplate 3, the outer casing 1, and the display panel 2 are all made of materials with elastic deformation capabilities.

[0029] Specifically, the mounting surface card 3 is connected to the outer casing 1 via a snap-fit ​​connection between the positioning groove 102 and the card protrusion 301.

[0030] The outer casing 1 is provided with a positioning groove 102, and the mounting surface clip 3 is U-shaped with clip protrusions 301 integrally formed at both ends (e.g., Figure 3 (It is provided in both the upper and lower directions), and the engagement is achieved by inserting the protrusion 301 into the positioning groove 102.

[0031] Specifically, sometimes it may be necessary to install other accessories, or there may be other situations at the opening on the cabinet panel 4 that affect the thickness (for example, there may be obstructing screws that cause the cabinet panel 4 to be installed as an auxiliary plate, or cables installed against the wall that cause the contact area of ​​the cabinet panel 4 to become thicker). In this case, multiple positioning slots 102 can be set, and the protrusion 301 can be selected to be inserted into which positioning slot 102 according to the actual situation on site. That is, one protrusion 301 corresponds to multiple positioning slots 102 (the length of the protrusion 301 and positioning slot 102 in the figure can actually be shorter, so that multiple can be arranged).

[0032] Specifically, since only minor adjustments may be needed, the distance may be too large when switching between multiple positioning slots 102. Therefore, the length of the positioning slot 102 is set to be greater than that of the latching protrusion 301, so that the latching protrusion 301 can slide and adjust within the positioning slot 102. However, this will cause the longitudinal fixation to loosen. Therefore, the longitudinal fixation is achieved between the mounting surface clip 3 and the outer shell 1 through a positioning structure, and the lateral limit is provided by the snap-fit ​​between the positioning slot 102 and the latching protrusion 301 in conjunction with the positioning structure, thereby achieving the fixation of the entire position.

[0033] Specifically, to facilitate operation and prevent springback during fixing from affecting installation efficiency, the positioning structure includes a wedge-shaped clip 302 set on the mounting surface clip 3 and multiple wedge-shaped teeth 103 on the outer shell 1 (to ensure sufficient adjustment distance), as shown in the figure. Figure 6 and 7 The two wedge-shaped inclined surfaces shown are aligned, and their fit together prevents backflow during use.

[0034] Specifically, in order to facilitate the connection between the wedge-shaped clip 302 and the wedge-shaped tooth 103 during installation, the tail end of the mounting surface clip 3 is provided with an outward flange 303. During installation, by squeezing the outward flange 303, the mounting surface clip 3 can be moved towards the folded edge 101, thereby squeezing the cabinet panel 4 and thus fixing its position.

[0035] Specifically, the outer shell 1 is provided with a buckle 104, and the display panel 2 is provided with a buckle groove 201. The outer shell 1 and the display panel 2 are connected by the buckle 104 and the buckle groove 201.

[0036] Usage process: First, insert the main body of the outer casing 1 into the opening of the cabinet panel 4. Then, install the electrical equipment inside the outer casing 1 according to the actual situation on site and connect the corresponding cables to the inner distribution cabinet. Then, take the mounting face clip 3 and clip it onto the side of the outer casing 1, so that the clip protrusion 301 is inserted into the corresponding position 102. Then, push the outer flange 303 with your finger to move the mounting face clip 3 toward the folded edge 101. At this time, the wedge clip 302 and the wedge tooth 103 continuously bite together, causing the buffer clip 5 to deform and squeeze the inner side wall of the opening of the cabinet panel 4. After that, install the electronic components of the operation panel in the display panel 2 and connect the corresponding circuits. Then, connect the clip groove 201 on the display panel 2 to the clip ear 104 on the outer casing 1 to complete the installation.

[0037] Conversely, when disassembling, the display panel 2 should be removed first (to remove the wiring connection). Use your fingers (or a flathead screwdriver to pry) to pry the wedge-shaped clip 302 outwards so that the wedge-shaped clip 302 can be loosened from the wedge-shaped teeth 103 and pulled back. Then, use force to deform the two ends of the mounting surface clip 3 so that the clip protrusion 301 can be disengaged from the positioning groove 102.

[0038] 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.
