[0007] As a further scheme of the utility model, the upper cover is fixed on the bottom hole of the power distribution box through a fixing screw.

[0008] Compared with the prior art, the utility model has the beneficial effects that: as long as the tilting action occurs, the power supply of the power distribution box can be cut off, the safety of the personnel is ensured, the electric shock of the personnel and the property loss are greatly eliminated, in addition, the device can also be applied to various required equipment, for example, a warmer, an electric heating fan, an electric fan, a power distribution box, a tea bar machine and hot oil, the device is resistant to corrosion, the device function is sensitive, firm and durable, and is not easy to be damaged. BRIEF DESCRIPTION OF DRAWINGS

[0009] Fig. 1 It is a whole structure schematic view of the utility model.

[0010] Fig. 2 The utility model discloses a schematic diagram of the button self-resetting switch after being removed.

[0011] Fig. 3 The utility model discloses a pendulum connecting rod schematic diagram.

[0012] Among them: 1 upper cover, 2 lower cover, 3 threaded section, 4 pendulum, 5 ball steel ball top piece, 6 hollow tube, 7 pendulum connecting rod, 8 fixed steel ball, 9 ball steel ball. Specific implementation

[0013] The utility model discloses will refer to the drawing and combine the embodiment to explain in detail.

[0014] Please refer to Figs. 1-3 The utility model provides a distribution box tilting power-off device, its structure includes a button self-resetting switch, and the button self-resetting switch is equipped with upper cover 1, and the button self-resetting switch top still is equipped with button self-resetting switch plug, and the button self-resetting switch is the product that market directly buys, and can be assembled according to product manual, and the structure is not repeated here.

[0015] Still include lower cover 2, and lower cover 2 is equipped with internal thread and bottom hole, and lower cover 2 is connected with the lower part of hollow tube 6 with external thread with screw thread, and the upper part of hollow tube 6 is connected with the upper cover 1 with internal thread with screw thread, and the lower bottom surface of upper cover 1 and the upper bottom surface of lower cover 2 are attached;Still include the pendulum 4 of setting threaded hole, and the threaded section 3 of pendulum connecting rod 7 is inserted into the threaded hole and is connected with the pendulum 4 with screw thread, and the top end of pendulum connecting rod 7 is fixedly connected with fixed steel ball 8, and the top end of fixed steel ball 8 is fixedly connected with ball steel ball 9, and fixed steel ball 8 is placed in the inside of hollow tube 6, and fixed steel ball 8 is large in volume, and can not pass the hole, and the hole contains pendulum connecting rod 7 through and is inclined;And ball steel ball top piece 5 is equipped between button self-resetting switch and ball steel ball 9.

[0016] The upper cover 1 is fixed in the distribution box bottom hole through fixed screw, under normal power supply condition, pendulum connecting rod 7 is vertical. Button self-resetting switch and the circuit connection of distribution box: button self-resetting switch normally closed end and public end are connected in series on AC contactor A1, A2 normally open terminal. Button self-resetting switch action control AC contactor on-off.

[0017] Ball steel ball top piece 5, position is represented with alphabet A, B, A point is other area, and B point is central point area.

[0018] When pendulum connecting rod 7 is vertical, ball steel ball 9 is at B point of ball steel ball top piece 5, ball steel ball top piece 5 is at the highest position at this time, and ball steel ball top piece 5 triggers button self-resetting switch to close and make it power on upward.

[0019] When the distribution box is tilted, the pendulum 4 is tilted to one side, the steel ball is at point A, the top piece 5 of the steel ball moves down, the button self-resetting switch resets, and the power-off action is completed.
