[0003] The analog indicator generally includes an analog indicator and wiring terminals on both sides. Electrical components are installed inside the analog indicator. The wiring terminals and the switch cabinet are connected through the two ends of the connecting wire, so that the switch analog indicator can control the switch cabinet and perform intelligent simulation dynamic indication.

When exposed for a long time, external dust can easily enter the inside of the wiring terminals and cause damage to the switch status analog indicator. It is inconvenient to protect the wiring terminals on both sides after use. In view of the shortcomings of the existing technology, we propose a switch status analog indicator to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The embodiment of the present application solves the problem of inconvenience in protecting the wiring terminals on both sides after use and reducing the service life of the switch status simulation indicator by providing a switch status simulation indicator, thereby achieving the function of protecting the wiring terminals on both sides after use.

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] The embodiment of the utility model discloses a switch state simulation indicator.

[0030] According to the attached Figure 1-6 As shown, it includes an indicator body 1, which is a switch state analog indicator of model MT-ZT140E. A mounting shell 2 is installed on one side of the indicator body 1, and wiring terminals 3 are installed on both sides of the mounting shell 2. Protection units 4 are provided outside the wiring terminals 3 on both sides. The protection unit 4 includes:

[0031] The protective frame 401 is located on both sides of the outside of the terminal block 3. Before use, the protective frames 401 on both sides are opened to expose the terminal block 3, and the connecting wires are connected to the terminal blocks 3 on both sides, and the other ends of the connecting wires are connected to the device, so that the dynamic indication device of the device can be intelligently simulated, and it also has control functions such as high-voltage live locking, automatic heating control, and temperature control.

[0032] The driving gear 4024 is located on one side wall of the protective frame 401, and an upper rack 4021 and a lower rack 4022 are respectively provided at the top and bottom ends of the driving gear 4024; after use, by sliding the protective frames 401 on both sides on the outer peripheral wall of the terminal 3, the terminal 3 can be protected to prevent external dust from entering the interior of the terminal 3 and causing damage.

[0033] The upper rack 4021 and the lower rack 4022 are meshed with the driving gear 4024, and the upper rack 4021 and the lower rack 4022 are connected to the protective frame 401. The ends of the upper rack 4021 and the lower rack 4022 that are away from each other are connected with a locking rod 403. The locking rod 403 has the function of locking the mounting shell 2 and the indicator body 1. By rotating the rotating member 4025 on one side, the driving gear 4024 is rotated to mesh with the upper rack 4021 and the lower rack 4022 at both ends, and the protective frames 401 on both sides are driven away from each other to open the protective frames 401. For details, please refer to the attached Figure 4 .

[0034] The protection frame 401 is slidably connected to the outer wall of the terminal block 3, and the driving gear 4024 rotates to drive the protection frames 401 on both sides to slide. The outer wall of one side of the indicator body 1 is fixedly connected to the mounting frame 101, and the outer walls of both sides of the mounting shell 2 are fixedly connected to the connecting pieces 201. The rotating pieces 4025 are rotated in opposite directions, so that the connecting blocks 4023 on both sides drive the protection frames 401 on both sides to approach each other, slide on the outer wall of the terminal block 3 to block and protect it. For details, please refer to the attached Figure 5 .

[0035] The connecting piece 201 is inserted into the interior of the installation frame 101, and one end of the locking rod 403 penetrates the outer wall of the installation frame 101. When the driving gear 4024 rotates to drive the protective frames 401 on both sides to approach, the installation of the mounting plate 4031 on one side can drive the locking rods 403 on both sides to be inserted into the interior of the installation frame 101 and the connecting piece 201 to lock it, thereby realizing a firm connection between the installation shell 2 and the indicator body 1. The locking rod 403 is inserted into the interior of the connecting piece 201, and the outer walls of the two sides of the installation shell 2 are fixed. A functional frame 402 is connected, and the upper rack 4021 and the lower rack 4022 are both slidably connected inside the functional frame 402. It should be noted that one end of the mounting shell 2 is plugged into the side wall of the indicator body 1. When the wiring terminal 3 is exposed to connect the connecting wire, even if the locking rod 403 is separated from the mounting frame 101 and the inside of the connector 201, the mounting shell 2 and the indicator body 1 will not be separated. The locking rod 403 is only used to further lock the mounting shell 2 and the indicator body 1 when not in use.

[0036] One end of the driving gear 4024 is fixedly connected to a rotating member 4025, and the rotating member 4025 is located on one side outer wall of the functional frame 402. A connecting block 4023 is fixedly connected to one side wall of the upper rack 4021 and the lower rack 4022. The connecting block 4023 has the function of connecting the two sets of racks to the protective frame 401. The side walls of the connecting block 4023 are respectively fixedly connected to the outer walls of the protective frame 401. At the same time, when the device needs to be repaired, the upper rack 4021 and the lower rack 4022 are used to drive the protective frames 401 on both sides away from each other, so that the wiring terminals 3 are exposed, and the locking rods 403 on both sides can be detached from the inside of the installation frame 101 and the connector 201, thereby facilitating the separation of the installation shell 2 from the indicator body 1 at the front end to repair the internal components and the wiring terminals 3.

[0037] A mounting plate 4031 is fixedly connected to one end of the upper rack 4021 and the lower rack 4022 that is away from each other, and an inner wall of the mounting plate 4031 is fixedly connected to one end of the locking rod 403 .

[0038] In summary, compared with the prior art, the invention has the following beneficial effects: through the cooperation between the driving gear 4024, the two sets of racks and the connecting block 4023, the protective frame 401 can be slid on the outer peripheral wall of the connecting terminal 3 to protect it when not in use, and at the same time, the mounting plates 4031 on both sides can drive the locking rod 403 to lock the mounting shell 2 and the indicator body 1, thereby improving the service life of the indicator body 1, and firmly connecting the mounting shell 2 and the indicator body 1, and at the same time, facilitating the later maintenance work of the indicator body 1.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
