Abstract

Disclosed is a falling switch including a switch body arranged on a support; a static contact piece and a movable contact piece are arranged respectively at the two sides of the switch body; a swing hammer is hung on the support through a swing rod; a ceramic rod is arranged on the switch body in a sliding manner; one end of the ceramic rod is in pressure connection with the top part of the swing rod and the other end of the ceramic rod is arranged under the movable contact piece; a movable contact on the movable contact piece and a static contact on the static contact piece are in pressure connection; the support is provided with a warping plate, one end of which is clamped between one end of the ceramic rod and the top part of the swing rod; and one end of the warping plate is a free end and the other end of the warping plate is hinged onto the support or one end of the warping plate is a free end and the other end of the warping plate is clamped on the support. When the falling switch is turned by 180 degrees, that is, when the falling switch is inverted by 180 degrees, the movable contact on the movable contact piece and the static contact on the static contact piece can still be separated under the action of the swing hammer and the swing rod so that safety performance is truly improved. The falling switch has the characteristics of being simple and reasonable in structure and flexible in operation.

Description

Tumbler switch

Technical field

The utility model relates to a kind of tumbler switch.

Background technology

Existing tumbler switch, shown in accompanying drawing 1-accompanying drawing 2, body 6 is arranged on the support 2, static contact 1 and movable contact spring 3 are separately positioned on the both sides of body 6, pendulum 4 is articulated on the support 2 by fork 4.1, and that slides in the body 6 is provided with porcelain rod 5, and an end of this porcelain rod 5 is crimped on the top of fork 4.1, the other end of porcelain rod 5 is positioned at the below of movable contact spring 3, and the fixed contact of the moving contact on the movable contact spring 3 on static contact 1 is crimped on.

During the work of the tumbler switch of this structure, drive forks 4.1 swings by pendulum 4, thereby the porcelain rod 5 that promotes to be arranged in body 6 moves upward, make that the moving contact on the movable contact spring 3 separates with fixed contact on the static contact 1, reach the purpose of falling and cutting off the power supply.

At present, there is a serious problem in this tumbler switch, when tumbler switch turns over turnback, even pendulum 4 and fork 4.1 are in bias state, moving contact on the movable contact spring 3 can not separate with fixed contact on the static contact 1, that is to say, does not have the purpose of the outage of falling.

The utility model content

The purpose of this utility model aims to provide a kind of simple and reasonable, flexible operation, tumbler switch that safe coefficient is high, to overcome weak point of the prior art.

A kind of tumbler switch by this purpose design, comprise the body that is arranged on the support, static contact and movable contact spring are separately positioned on the both sides of body, pendulum is articulated on the support by fork, that slides in the body is provided with the porcelain rod, one end of this porcelain rod is crimped on the top of fork, the other end of porcelain rod is positioned at the below of movable contact spring, the fixed contact of moving contact on the movable contact spring on static contact is crimped on, its architectural feature is also to be provided with seesaw on the support, and an end of this seesaw is folded between the top of an end of porcelain rod and fork.

One end of described seesaw is free end, and the other end of seesaw is hinged on the support.

One end of described seesaw is free end, and the other end of seesaw is installed on the support.

After the utility model adopts above-mentioned technical scheme, when tumbler switch turns over turnback, that is to say that tumbler switch is inverted 180 when spending, the moving contact on the movable contact spring still can separate under the effect of pendulum and fork with fixed contact on the static contact, has improved security performance conscientiously.

The utility model has been set up seesaw on the basis of existing product, improved sensitivity, can omnibearing protection, and safety outage under abnormal operating state has simple and reasonable, flexible operation, characteristics that safe coefficient is high.

Description of drawings

Fig. 1 is the main TV structure schematic diagram of existing tumbler switch.

Fig. 2 is the left TV structure schematic diagram of Fig. 1.

Fig. 3 is the biopsy cavity marker devices structural representation of the utility model one embodiment.

Fig. 4 is the right TV structure schematic diagram of Fig. 3.

Fig. 5 is the plan structure schematic diagram of Fig. 3.

Among the figure: 1 is static contact, and 2 is support, and 3 is movable contact spring, and 4 is pendulum, and 4.1 is fork, and 5 is the porcelain rod, and 6 is body, and 7 is seesaw.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

Referring to Fig. 3-Fig. 5, this tumbler switch, comprise the body 6 that is arranged on the support 2, static contact 1 and movable contact spring 3 are separately positioned on the both sides of body 6, pendulum 4 is articulated on the support 2 by fork 4.1, that slides in the body 6 is provided with porcelain rod 5, one end of this porcelain rod 5 is crimped on the top of fork 4.1, the other end of porcelain rod 5 is positioned at the below of movable contact spring 3, the fixed contact of moving contact on the movable contact spring 3 on static contact 1 is crimped on, also be provided with seesaw 7 on the support 2, an end of this seesaw 7 is folded between the top of an end of porcelain rod 5 and fork 4.1.

Wherein, an end of seesaw 7 is free end, and the other end of seesaw 7 is hinged on the support 2; Perhaps, an end of seesaw 7 is free end, and the other end of seesaw 7 is installed on the support 2.

During work, pendulum 4 and fork 4.1 promote seesaw 7, promote porcelain rod 5 by seesaw 7 again, and porcelain rod 5 rises moving contact and fixed contact are separated, and realizes falling outage.
