[0019] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified.

[0020] like Figure 1-4As shown, the utility model provides a protective switch box, including a protective box 1, on which an observation window 2 is provided for observing the inside of the protective box 1 from the outside. A slope 19 is provided on the top of the protective box 1, and a measuring switch 3 and a porcelain bottle 5 are fixedly provided inside the protective box 1, and a switch 4 and two layers of terminal posts 18 are provided on the measuring switch 3. A partition 9 is provided between the measuring switch 3 and the porcelain bottle 5, and the porcelain bottle 5, the partition 9, the side wall and the bottom wall of the protective box 1 are all provided with wire holes. A plurality of fixing holes 8 are provided on the measuring switch 3, which are used to fix the measuring switch 3 inside the protective box 1.

[0021] When in use, the power line enters from the side wall of the protection box 1, passes through the porcelain bottle 5 and the partition 9 in sequence, is connected to the upper terminal 18, and then leads out from the lower terminal 18 to the user circuit. By setting the porcelain bottle 5, good insulation performance can be achieved, and setting the porcelain bottle 5 inside the protection box 1 can prevent other wires or communication lines from being hung.

[0022] By using the measuring switch 3, the circuit can be protected from overload or short circuit damage, and has the functions of automatic resetting and transmitting electrical quantity data.

[0023] like Figure 4 As shown, an observation hole 7 is provided on the terminal 18. By providing the observation hole 7, it is convenient to observe the operation during wiring; when put into use, it can be used to observe the wiring status.

[0024] The protection box 1 is also fixedly provided with a mounting plate 6 outside, and the mounting plate 6 is used to mount the protection box 1 on the wall 17. Figure 5 As shown in FIG. 6 , a through hole is provided in the wall 17, a pipe sleeve 12 is fixedly connected to the wall 17, at least two notches 13 are provided on the side wall of the pipe sleeve 12, a clamping member 15 is slidably fitted in the notch 13, a bolt 10 passes through the through hole, a thread is provided on the inner side wall of the pipe sleeve 12, the bolt 10 matches the thread, an end of the bolt 10 extending into the pipe sleeve 12 is provided with an inclination 14, and the axis of the bolt 10 is aligned with the contact surface of at least two clamping members 15.

[0025] A groove 11 is provided on the wall 17. When in use, the pipe sleeve 12 is inserted into the groove 11 on the wall 17, and the bolt 10 is tightened. The bolt 10 moves along the axis of the pipe sleeve 12 toward the clamping member 15, so that the inclination 14 of the end of the bolt 10 presses against the end surface of the clamping member 15, pushing the clamping member 15 to move outward, and finally the outer end of the clamping member 15 is clamped with the side wall of the groove 11 to achieve the fixing function. The clamping member 15 can be pressed along with the bolt 10, so that the clamping member 15 can continue to press the inner wall of the groove 11, and will not be disengaged. This enhances the firmness of its fixing.

[0026] The cross section of the notch 13 is a triangular structure or a square structure. By setting the notch 13 to a triangular structure or a square structure, the clamping member 15 is prevented from rotating, which affects the pushing of the bolt 10 on the clamping member 15. A cone 16 is provided at one end of the clamping member 15 away from the bolt 10. By providing the cone 16 at the end of the clamping member 15, the clamping performance of the clamping member 15 and the groove 11 can be improved.

[0027] The opposite surfaces of adjacent clamping members 15 are provided with inclined surfaces, and the angle of the inclined surfaces matches the angle of the inclination 14. The inclined surfaces make it easier for the bolt 10 to push the clamping member 15 to move. The length of the clamping member 15 is equal to the radius of the outer wall of the sleeve 12, the thread length of the bolt 10 is greater than the sum of the length of the sleeve 12 and the thickness of the mounting plate 6, and the outer diameter of the sleeve 12 is smaller than the inner diameter of the groove 11.

[0028] In the description of the present invention, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "middle", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0029] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
