Description

Technical Field

[0001] This utility model relates to the field of electrical cabinets, and in particular to a fixing structure for an anti-disassembly nameplate for electrical cabinets. Background Technology

[0002] The nameplate of an electrical cabinet is an identification label installed on the outside of the electrical cabinet. It is mainly used to provide key technical parameters and basic information of the equipment. It not only facilitates users to correctly install, operate and maintain the equipment and ensure electrical safety, but also provides an important basis for subsequent inspection, acceptance, patrol inspection and troubleshooting. It is the core certificate of compliance and traceability of electrical equipment. Therefore, the installation and fixing of the nameplate is particularly important.

[0003] For example, patent number CN222981057U discloses an electrical cabinet with nameplate protection function, including a cabinet body (1), a mounting base (2) is provided on the outside of the cabinet body (1), a mounting groove (3) is provided on the side of the mounting base (2) away from the cabinet body (1), a nameplate body (4) is embedded in the mounting groove (3), and the information side of the nameplate body (4) is set outward; a visible panel (5) for covering the nameplate body (4) is covered on the mounting base (2). The visible panel (5) for covering the nameplate body (4) of this utility model can prevent external dust and oil stains from corroding the information on the nameplate body (4), so that the nameplate information is valid for a long time and convenient for maintenance personnel to read.

[0004] For example, patent number CN207939002U discloses a nameplate mounting structure for switch cabinets, including a base plate and a nameplate. The nameplate has one or more nameplate mounting through holes, and the base plate has base plate mounting through holes corresponding to the nameplate mounting through holes. A rubber sleeve that can pass through both the base plate mounting through hole and the nameplate mounting through hole is installed in the nameplate mounting through hole. A rubber pin that can expand the rubber sleeve and engage with the base plate is inserted in the rubber sleeve.

[0005] Existing electrical cabinet nameplates are generally fixed with screws at the four corners. Although some designs add external protective structures to protect the nameplates or use special adhesive nails to simplify the installation process, it is difficult to meet the dual requirements of preventing unauthorized disassembly and convenient replacement in practical applications. In particular, the easy-to-disassemble structure makes it easy for the nameplate to be replaced at will, resulting in the distortion of equipment information and affecting operation and maintenance traceability and safety management. On the other hand, irreversible fastening methods such as adhesive nails have good anti-disassembly properties, but they cannot achieve non-destructive disassembly and reinstallation of the nameplate, which brings inconvenience to the subsequent replacement of the nameplate.

[0027] Please see Figures 1-4 In this embodiment, the fixed frame 2 and the limiting seat 5 are both fixedly connected to the surface of the electrical cabinet door 1. The left side of the limiting seat 5 and the fixed frame 2 are tightly fitted. A transparent protective plate is provided on the front side of the fixed frame 2. The placement groove 4 is arranged to pass through the fixed frame 2 from left to right. The nameplate body 3 and the inner side of the placement groove 4 are mutually adapted. The left end of the nameplate body 3 abuts against the limiting seat 5. The magnetic suction piece 6 is embedded in the right side of the limiting seat 5. The left side of the nameplate body 3 is magnetically connected to the magnetic suction piece 6. The right end of the movable groove 7 extends to the right side of the limiting seat 5 and is connected to the placement groove 4. The ejector piece 8 is slidably connected to the inner side of the movable groove 7. The right end of the ejector piece 8 abuts against the left end of the nameplate body 3. The nameplate body 3 is inserted into the placement groove 4 until the left end of the nameplate body 3 is attracted and fixed by the magnetic suction piece 6 and abuts against the limiting seat 5. At this time, the nameplate body 3 is initially positioned in the fixed frame 2, which is convenient and quick.

[0028] Please see Figures 2-6In this embodiment, the knob 901 is rotatably connected to the surface of the box 9. The front end of the knob 901 extends to the inner side of the box 9 and is fixedly connected to the rear end of the adjusting screw 10. The front end of the adjusting screw 10 is rotatably connected to the electrical cabinet door 1. The movable frame 11 is threadedly connected to the outer side of the adjusting screw 10. The upper and lower sides of the movable frame 11 slide against the inner side of the box 9. Four locking rods 12 are provided on the surface of the movable frame 11 and are fixedly connected to the movable frame 11. The locking rods 12 are slidably connected to the inner side of the through hole 13. The front end of the locking rod 12 extends through the through hole 13 to the inner side of the placement slot 4 and abuts against the fixed frame 2. The locking rods 12 are arranged to pass through the limiting hole 301 from front to back. Rotating the knob 901 on the back of the electrical cabinet door 1 causes the adjusting screw 10 to rotate, which in turn moves the moving frame 11 forward. The locking rod 12 passes through the limiting hole 301 along the through hole 13 and abuts against the fixed frame 2, thus locking the nameplate body 3. When the nameplate body 3 needs to be disassembled and replaced, the operator can use the key to open the electrical cabinet door 1 and then rotate the knob 901 in the opposite direction to control the locking rod 12 to retract into the through hole 13, thus releasing the lock on the nameplate body 3. At this time, by pushing the toggle block 801, the ejector plate 8 slides along the movable groove 7, pushing the nameplate body 3 away from the limiting seat 5, so that the nameplate body 3 is disengaged from the magnetic plate 6 and extends out of the fixed frame 2 from the right end of the placement groove 4, making it convenient to remove and replace the nameplate body 3.

[0029] When installing the nameplate, insert the nameplate body 3 into the placement slot 4 until the left end of the nameplate body 3 is attracted and fixed by the magnetic piece 6, abutting against the limiting seat 5. At this time, the nameplate body 3 is initially positioned within the fixing frame 2, which is convenient and quick. The limiting hole 301 is aligned with the through hole 13. By rotating the knob 901 on the back of the electrical cabinet door 1, the adjusting screw 10 is rotated, causing the moving frame 11 to move forward. The locking rod 12 passes through the limiting hole 301 along the through hole 13 and abuts against the fixing frame 2, thereby locking the nameplate body 3. By closing the electrical cabinet door 1 and locking it, the nameplate body 3 cannot be arbitrarily replaced without the cabinet door key, avoiding the distortion of equipment information and affecting operation and maintenance traceability and safety. When the nameplate body 3 needs to be disassembled and replaced, the staff can use the key to open the electrical cabinet door 1, and then turn the knob 901 in the opposite direction to control the locking rod 12 to retract into the through hole 13, thereby releasing the lock on the nameplate body 3. At this time, by pushing the toggle block 801, the ejector plate 8 slides along the movable groove 7, pushing the nameplate body 3 away from the limit seat 5, so that the nameplate body 3 is disengaged from the magnetic suction plate 6, and the fixed frame 2 extends out from the right end of the placement groove 4, making it convenient to remove and replace the nameplate body 3. When the nameplate body 3 is placed into the fixed frame 2 after the replacement, the ejector plate 8 can be automatically reset as the nameplate body 3 is attached to the limit seat 5. The ejector plate 8 can also be reset in advance by pushing the toggle block 801.

[0030] Compared to the prior art (patent number CN222981057U), which protects the nameplate by adding an external protective structure, this application adds a quick-positioning and anti-disassembly quick-fixing structure to the protective structure. When installing the nameplate, the nameplate body 3 is inserted into the placement slot 4 until the left end of the nameplate body 3 is attracted and fixed by the magnetic piece 6, achieving quick positioning of the nameplate body 3. Rotating the knob 901 causes the adjusting screw 10 to move the moving frame 11 forward, and the locking rod 12 passes through the limiting hole 301 and abuts against the fixing frame 2, locking the nameplate body 3. Closing and locking the electrical cabinet door 1 ensures that the nameplate body 3 can be secured even without the cabinet key. The nameplate body 3 cannot be arbitrarily replaced, providing good anti-tamper performance and preventing equipment information distortion from affecting operation and maintenance traceability and safety management. Compared with the prior art (patent number CN207939002U) and common existing technologies that use fixing nails at the four corners for fixation, this application adds an auxiliary disassembly structure on the basis of ensuring anti-tamper performance. When it is necessary to disassemble and replace the nameplate body 3, the locking rod 12 is retracted into the through hole 13 by the knob 901, releasing the lock on the nameplate body 3. The pusher 801 drives the ejector plate 8 to push the nameplate body 3 out of the fixing frame 2, making it convenient and quick to remove and replace the nameplate body 3.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] 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.
