[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. 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.
[0023] Please see Figure 1-5 This utility model provides a technical solution: an intelligent measuring switch, including a switch body 1, with mounting holes 1.1 at the top and bottom of the switch body 1.
[0024] The fixing plate 2 has grooves 2.1 at each of its four corners, and fixing holes 2.2 are respectively located in the middle of the rear wall of the grooves 2.1. The fixing plate 2 is fixed to the rear wall of the protective box or the groove through the fixing holes 2.2 using screws.
[0025] The connecting frame 3 includes a central block 3.1, vertical plates 3.2 fixed to the two sides of the front center of the top and bottom faces of the central block 3.1, and a connecting block 3.3 integrally formed on the front of the other end of the vertical plates 3.2. A slot 3.1.1 is provided in the middle of the rear wall of the central block 3.1 along the horizontal direction. The rear end of the screw fitted in the mounting hole 1.1 is threaded into the corresponding connecting block 3.3 to fix the switch body 1 to the front wall of the connecting frame 3.
[0026] The front and rear ends of the scissor-type telescopic mechanism 4 are respectively connected to the rear wall of the connecting frame 3 and the front wall of the fixing plate 2. The scissor-type telescopic mechanism 4 includes a scissor-type telescopic link 4.1 and connecting plates 4.2 located at the front and rear ends of the scissor-type telescopic link 4.1. A strip 4.3 is horizontally fixed to one end of the link on one side of the front and rear ends of the scissor-type telescopic link 4.1. A groove 4.3.1, which slides and engages with the corresponding end of the link, is provided in the middle of the strip 4.3. An ear plate 4.4 is fixed to the connecting plate 4.2 and hinged to the other end of the link on the other side of the front and rear ends of the scissor-type telescopic link 4.1. The connecting plate 4.2 at the front of the scissor-type telescopic mechanism 4 is fixed to the front wall of the cavity of the slot 3.1.1 using screws, and the connecting plate 4.2 at the rear of the scissor-type telescopic mechanism 4 is fixed to the middle of the front wall of the fixing plate 2 using screws. The middle part of the scissor-type telescopic link 4.1 is slidably engaged with the slot 3.1.1.
[0027] In summary, the switch body 1 is an NM3N series intelligent measurement switch. When installing the switch, first assemble and connect the switch body 1, the fixing plate 2, the connecting bracket 3, and the scissor-type telescopic mechanism 4. Then, extend the scissor-type telescopic mechanism 4 to its longest position so that the fixing plate 2 can be fixed to the rear wall of the inner cavity of the protective box or the slot.
[0028] Push the switch body 1 backward so that the scissor telescopic mechanism 4 retracts to its shortest state, and the scissor telescopic link 4.1 is fully housed in the slot 3.1.1, with the rear wall of the middle block 3.1 attached to the front wall of the fixing plate 2.
[0029] When inspection or maintenance of the switch body 1 is required, the switch body 1 is first pulled outward, causing the scissor-type telescopic linkage 4.1 to extend inward. This allows the switch body 1 to extend out of the protective box or slot cavity, facilitating inspection and maintenance. To allow the switch body 1 to move forward, sufficient spare length in the connecting lines is necessary.
[0030] To ensure stability and prevent wobbling after the switch body 1 is reset, bar magnets 3.4 are nested on the rear wall of the middle block 3.1 at the upper and lower sides of the slot 3.1.1, and the fixing plate 2 is made of iron. The switch body 1 is securely fixed by the magnetic attraction between the bar magnets 3.4 and the fixing plate 2.
