Specific embodiment

The utility model is described further referring to attached drawing.

Present embodiment discloses a kind of anti-dumping switch, as shown in Figure 1, including shell 1, which is two combinations Shell 2 is composed, and facilitates installation.

As shown in Fig. 2, the second cavity 4 for being provided with the first cavity 3 in shell 1 and being connected to the first cavity 3, the first cavity It is placed with a heavy ball 5 moveing freely in 3, driving end 6 is rotatably connected in shell 1, is equipped in the second cavity 4 and is controlled by driving Control assembly 7 of the end 6 to be switched on or off.

As shown in Figure 2 and Figure 3, control assembly 7 includes the first insertion piece 8, second insertion piece 9, spring leaf 10, arc edge 11 and movable contact spring 12, it integrally generates for limit the first aperture 13 and the first slot 14 that first is inserted into piece 8 on shell 1, the One aperture 13 and the setting of the first slot 14 play the role of stablizing the first insertion piece 8；It integrally generates on shell 1 for limiting Second aperture 15 of the second insertion piece 9 and the second slot 16, the second aperture 15 and the setting of the second slot 16, which play, stablizes the The effect of two insertion pieces 9.It is fixed with moving contact on movable contact spring 12, is fixed with static contact on the first insertion piece 8, when movable contact spring 12 is remote When one end from the first insertion piece 8 moves down, movable contact spring 12 is whole to be moved down so that moving contact and static contact abutting, are realized The conducting of first insertion piece 8 and the second insertion piece 9；When the power that movable contact spring 12 is subject to far from one end of the first insertion piece 8 is less than bullet When the elastic force of reed 10, movable contact spring 12 is whole to move up and makes moving contact and static contact to separate, and realizes the first insertion 8 He of piece The open circuit of second insertion piece 9.

As shown in Fig. 2, driving end 6 includes integrally formed hinged end 17, mobile jib 18, down-pressed pole 19 and far from hinged The force side 20 in portion；Integrally formed setting is so that entirely driving end 6 is stronger.Hinged end 17 is arranged in cylinder, in shell 1 It is provided with corresponding to hinged end 17 and is connected to the circular groove 21 of the second cavity 4, after hinged end 17 is inserted into circular groove 21, drives end 6 It can be around the axis rotation of circular groove 21.The diameter of hinged end 17 is greater than the width of the opening of circular groove 21, so that hinged end 17 is in circular groove It is more stable in 21.Force side 20 is located at 5 lower section of heavy ball, and when shell 1 is placed vertically, heavy ball 5 is moved to the perpendicular of the first cavity 3 Straight least significant end, while heavy ball 5 can abut with force side 20 and make that end 6 is driven to rotate down around the axle center of circular groove 21, at present Compression bar 19, which rotates down and resists movable contact spring 12, moves down movable contact spring 12, and moving contact and static contact abut.

As shown in Fig. 2, being equipped with limiting section 23 in the second cavity 4, the upper end of limiting section 23 is abutted with the bottom end of force side 20 To limit the maximum rotation distance at driving end 6, the bottom end of limiting section 23 is abutted with the top of movable contact spring 12 to limit movable contact spring 12 Maximum moving distance.The setting of limiting section 23 plays the moving range for limiting driving end 6 and movable contact spring 12, so that entire control Component 7 processed is more stable in the second cavity 4.

As shown in Figure 1, two combination shells 2 facilitate installation by connecting and fixing.It is provided between two combination shells 2 Bolt 22 is fixed, stronger after bolt 22 is fixed.

Specific effect is as follows: control assembly 7 being directly installed in shell 1 and original product compares, is reduced micro- It is dynamic to switch required shell, the use of material is not only reduced, is reduced costs, it in the process of production and processing, directly will control Component 7 processed is mounted in shell 1, is being mounted in shell 1 without first installing in microswitch, is being improved production efficiency.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Within novel design concept, any modification, equivalent replacement, improvement and so on should be included in the protection of the utility model Within the scope of.
