Description

Technical Field

[0001] This utility model relates to the field of nameplate installation technology, and in particular to nameplate fixing structures. Background Technology

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final stage equipment of the power distribution system. Distribution cabinets are a general term for motor control centers. In order to display the contents of the distribution cabinet, a nameplate is installed on the cabinet door.

[0003] Currently, during installation, adhesive tape is applied to the back of the nameplate, which is then used to attach the nameplate to the cabinet door. A notch is cut into the nameplate to house the display panel. However, this installation method has the following drawbacks: Firstly, the adhesive tape connects the nameplate to the cabinet door, but the adhesive properties of the tape cause the sticky layer to adhere to the cabinet door, forming stains and affecting the aesthetics of the distribution cabinet. Secondly, the nameplate only houses the display panel through the notch, while the electrical components inside the distribution cabinet cause vibrations during operation. Since the nameplate does not restrain the display panel, it can easily fall off, preventing the nameplate from displaying the internal conditions of the distribution cabinet. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the appearance of the cabinet door is affected by the nameplate being glued to the distribution cabinet with adhesive tape in the prior art, and to propose a nameplate fixing structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The nameplate fixing structure includes a nameplate mounted on a power distribution cabinet. The nameplate consists of a rear cover and a front cover. The front cover contains a display plate for displaying the specifications of the power distribution cabinet. The rear cover is fitted with a clamping structure for clamping the front cover. A positioning cylinder is fixedly mounted on the rear cover. A support rod extending into the positioning cylinder is fixedly mounted on the power distribution cabinet. The support rod is provided with a rubber ring that moves against the inner wall of the positioning cylinder. A limiting structure is installed on the power distribution cabinet for limiting the positioning cylinder.

[0007] Preferably, pressure rods extending into the rear cover are fixedly installed on both sides of the front cover, and a movable plate is slidably sleeved on the rear cover, with a wiping cloth for wiping the front cover installed on the movable plate.

[0008] Preferably, the clamp structure includes a rotating rod rotatably installed inside the rear cover, and a connecting end integrally connected to the rotating rod. A clamp seat is fixedly installed on the connecting end, and a positioning rod extending into the front cover is slidably sleeved inside the clamp seat. A spring is welded between the positioning rod and the clamp seat.

[0009] Preferably, the spring is vertically welded to the upper end of the positioning rod extending into the card seat, and the front cover has a positioning groove for limiting the positioning rod.

[0010] Preferably, the limiting structure includes a sleeve fixedly installed on the distribution cabinet, and three circumferentially distributed extrusion plates are slidably sleeved inside the sleeve to extrude the sleeve, and a spring is welded between the extrusion plates and the sleeve.

[0011] Preferably, the sleeve is an open, hollow annular structure, the extrusion plate is an arc-shaped structure that cooperates with the sleeve, and the spring is horizontally welded.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1.

[0022] 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.

[0023] Reference Figures 1-6 The nameplate fixing structure includes a nameplate installed on the power distribution cabinet. The nameplate consists of a rear cover 1 and a front cover 2, and a display plate for displaying the specifications of the power distribution cabinet is placed inside the front cover 2.

[0024] Pressure rods 3 extending into the rear cover 1 are fixedly installed on both sides of the front cover 2. A movable plate 15 is slidably sleeved on the rear cover 1, and a wiping cloth 16 for wiping the front cover 2 is installed on the movable plate 15. By setting pressure rods 3 on both sides of the front cover 2, the rear cover 1 clamps the pressure rods 3 from the inside, thereby increasing the contact area between the rear cover 1 and the front cover 2, so that the display board is in a sealed state during the display process. By pulling the movable plate 15, the movable plate 15 drives the wiping cloth 16 to wipe the front cover 2.

[0025] The rear cover 1 is equipped with a clamping structure for clamping the front cover 2.

[0026] The clamp structure includes a rotating rod 4 rotatably installed inside the rear cover 1, and a connecting end 5 integrally connected to the rotating rod 4. A clamp seat 6 is fixedly installed on the connecting end 5, and a positioning rod 7 extending into the front cover 2 is slidably sleeved inside the clamp seat 6. A spring 8 is welded between the positioning rod 7 and the clamp seat 6. The spring 8 resets the positioning rod 7. When the positioning rod 7 is in an unloaded state, the positioning rod 7 can extend into the positioning groove inside the front cover 2.

[0027] According to the instruction manual Figure 3 As shown, spring 8 is vertically welded to the upper end of the positioning rod 7 extending into the card seat 6. The front cover 2 has a positioning groove for limiting the positioning rod 7. Through the cooperation between the positioning rod 7 and the positioning groove, the upper end of the front cover 2 is made to fit against the inner wall of the rear cover 1. The deflection of the front cover 2 can limit the display board in the gap between the rear cover 1 and the front cover 2, so that the display board will not fall off when the power distribution cabinet is running.

[0028] A positioning cylinder 9 is fixedly installed on the back cover 1, and a support rod 10 extending into the positioning cylinder 9 is fixedly installed on the distribution cabinet. The support rod 10 is provided with a rubber ring 11 that moves against the inner wall of the positioning cylinder 9. By pressing the back cover 1, the back cover 1 drives the positioning cylinder 9 to extend onto the support rod 10. The rubber ring 11 can fully fit against the inner wall of the positioning cylinder 9 through compression. By connecting the nameplate to the distribution cabinet, the nameplate will not affect the aesthetics of the distribution cabinet when it is disassembled and reassembled later.

[0029] The distribution cabinet is equipped with a limiting structure for limiting the positioning cylinder 9.

[0030] The limiting structure includes a sleeve 12 fixedly installed on the distribution cabinet, and three circumferentially distributed extrusion plates 13 slidingly fitted inside the sleeve 12 to compress the sleeve 12. A second spring 14 is welded between the extrusion plates 13 and the sleeve 12. The sleeve 12 is an open hollow annular structure, and the extrusion plates 13 are arc-shaped structures that cooperate with the sleeve 12. The second spring 14 is horizontally welded. By setting the extrusion plates 13 as arc-shaped structures that cooperate with the sleeve 12, the contact area between the extrusion plates 13 and the sleeve 12 can be increased, so that the stability of the sleeve 12 can be fully guaranteed. The second spring 14 realizes the reset function of the sleeve 12. When the extrusion plates 13 are in an unloaded state, the second spring 14 can drive the extrusion plates 13 back to the initial position.

[0031] The functional principle of this utility model can be explained through the following operation methods:

[0032] When it is necessary to use a nameplate to display the specifications of the distribution cabinet;

[0033] Press the back cover 1 so that the back cover 1 drives the positioning cylinder 9 to correspond with the support rod 10 on the power distribution cabinet. When the support rod 10 and the positioning cylinder 9 correspond with each other, the outer wall of the positioning cylinder 9 will move against the extrusion plate 13. The spring 14 is under force so that the three extrusion plates 13 can clamp the outer wall of the positioning cylinder 9, thereby connecting the back cover 1 and the power distribution cabinet.

[0034] The display board is placed inside the front cover 2. The front cover 2 is lifted so that the positioning groove on the front cover 2 corresponds to the positioning rod 7. The front cover 2 is lifted and pressed. The front cover 2 squeezes the spring 8 through the positioning rod 7 and applies pressure to the lower end of the front cover 2. The front cover 2 is deflected through the positioning rod 7 with the rotating rod 4 as the fulcrum. The front cover 2 drives the pressure rod 3 to move and abut against the two sides of the rear cover 1, thereby covering the rear cover 1 with the front cover 2.

[0035] When the front cover 2 needs to be cleaned, the movable plate 15 is pulled so that the movable plate 15 drives the wiping cloth 16 to wipe the front cover 2.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
