[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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] A vacuum load switch with an indication function comprises a vacuum load switch body 1 and an opening and closing indication disk 2 arranged on the vacuum load switch body 1, wherein the vacuum load switch body 1 is connected with an opening and closing mark used in conjunction with the opening and closing indication disk 2, and the opening and closing mark comprises a connecting frame 3 and an indication plate 4, and the connecting frame 3 is fixed to the outer surface of the vacuum load switch body 1.

[0028] The front and back sides of the connecting frame 3 are both open in design to expose the indicator sign 4 inside the connecting frame 3. One side of the connecting frame 3 is open in design. An installation slot 5 is provided on the inner wall of the connecting frame 3. The indicator sign 4 is inserted into the installation slot 5. Two symmetrically arranged locking members 6 are fixedly connected to the connecting frame 3. A locking plate 7 is fixedly connected to the back side of the indicator sign 4 and between the two locking members 6.

[0029] like Figure 1The vacuum load switch body 1 with the opening and closing indicator disk 2 is in the prior art and will not be described in detail here. The indicator plate 4 is separated into two parts, "open" and "closed". The opening and closing state of the vacuum load switch body 1 can be grasped by the movement of the pointer part of the opening and closing indicator disk 2 on the indicator plate 4. The front and back sides of the connecting frame 3 are both open-type designs, so that the indicator plate 4 can be directly observed through the connecting frame 3. The back side of the connecting frame 3 is fixed to the surface of the vacuum load switch body 1.

[0030] The front side of the connecting frame 3 is provided with a receiving groove 8 , and a booster push block 9 is fixedly connected to the front side of the indicator sign 4 and located in the receiving groove 8 .

[0031] like Figure 2 The assisting push block 9 protrudes from the front of the indicator sign 4, and the assisting push block 9 is subjected to force, so as to assist in pushing the indicator sign 4 out of the installation slot 5. The installation slot 5 and the indicator sign 4 are adapted so that the indicator sign 4 can be clamped in the installation slot 5 by friction.

[0032] The locking member 6 includes a transverse connecting plate 601, which is fixed to the connecting frame 3. A first rubber block 602 and a second rubber block 603 are fixedly connected to the transverse connecting plate 601. One end of the first rubber block 602 is designed as an inclined surface, and one end of the second rubber block 603 is designed as an arc surface.

[0033] like Figure 3 and Figure 4 The two locking members 6 are symmetrically arranged. Through the inclined design of the first rubber block 602, the locking plate 7 can more easily open the two first rubber blocks 602 and pass through between the two first rubber blocks 602. Both the first rubber block 602 and the second rubber block 603 are elastic.

[0034] Both ends of the locking plate 7 are designed to be arc surfaces, and the top and bottom of the locking plate 7 are provided with arc grooves 701 for use with the second rubber block 603 .

[0035] like Figure 3 and Figure 4 By designing the two ends of the locking plate 7 as arc surfaces, the locking plate 7 can more easily pass between the two first rubber blocks 602 when the indicating sign 4 moves.

[0036] When the indicator sign 4 is pushed into the installation slot 5, one end of the locking plate 7 can squeeze the inclined surfaces of the two first rubber blocks 602, pass through between the two first rubber blocks 602, and open the arc surfaces of the two second rubber blocks 603, and finally make the arc surface of one end of the second rubber block 603 inserted into the arc groove 701, so as to assist in locking the locking plate 7 and the indicator sign 4;

[0037] Conversely, when the assisting push block 9 is pushed to one side, the indicating sign 4 can be driven to disengage from the inside of the installation slot 5. At the same time, the arc surface in the arc-shaped groove 701 presses the arc surface of the second rubber block 603, causing the second rubber block 603 to be compressed and contracted, and the locking plate 7 can disengage from between the two first rubber blocks 602 and the two second rubber blocks 603.

[0038] A limiting convex block 13 is fixedly connected to the inner surface of the connecting frame 3, and a limiting convex plate 14 that cooperates with the limiting convex block 13 is fixedly connected to the back surface of the indicating sign 4.

[0039] As Figure 3 , when the indicating sign 4 is installed and the orientation part of the indicating sign 4 is correct, the limiting convex plate 14 will be restricted by the limiting convex block 13, so that the indicating sign 4 cannot be inserted into the installation slot 5, ensuring that when the indicating sign 4 is inserted into the installation slot 5, the orientation of the indicating sign 4 will not deviate.

[0040] A plurality of fixing members 15 are fixedly connected to the vacuum load switch body 1. The fixing members 15 are in a "C" shape, and a fixing notch 16 and a fixing hole 17 are formed in the fixing members 15.

[0041] As Figure 1 and Figure 7 , the side of the fixing member 15 without the fixing notch 16 and the fixing hole 17 is fixed on the vacuum load switch body 1. Through the provided fixing notch 16 and fixing hole 17, the fixing of the fixing member 15 and the vacuum load switch body 1 can be assisted.

[0042] Compared with the related art, a vacuum load switch with an indicating function provided by the present utility model has the following beneficial effects:

[0043] In the present utility model, by setting the closing and opening marks as the separable connecting frame 3 and indicating sign 4, when the assisting push block 9 is pushed, the indicating sign 4 can be separately drawn out from the connecting frame 3 from one side of the installation slot 5, and the dust on the surface of the indicating sign 4 can be separately processed, avoiding the dust accumulation on the surface of the indicating sign 4 that cannot be clearly observed after long-term use, which affects the understanding of the closing and opening state of the vacuum load switch body 1. At the same time, when the indicating sign 4 is inserted into the installation slot 5 from one side, the first rubber block 602 and the second rubber block 603 can lock the locking plate 7 through friction, avoiding loosening of the indicating sign 4.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
