Abstract

The utility model discloses a triangular dead-weight controllable switch. Three chamfered grooves are distributed on the inner side of a switch base with a cylindrical casing; an approximately-triangular space is formed in the middle of the switch base; a triangular dead-weight block rotatable assembly is mounted in the triangular space and is formed by embedding a metal core into a triangular block; conductive metal sheets connected with leads are respectively attached to two sides of the three chamfered grooves of the switch base; and conductive metal sheets are attached to two sides of three angles of the triangular dead-weight block. When in use, the metal core in the triangular dead-weight block falls off under the action of gravity in the dynamic rotation environment, is contacted with a base angle of the switch base and can be automatically opened and closed. The utility model has the advantages of favorable stability, compact structure and high sensitivity.

Description

Triangle deadweight gate-controlled switch

Technical field

The utility model relates to a kind of sensitive switch, especially relates to the triangle deadweight gate-controlled switch that uses on a kind of robot or other article for rotation.

Background technology

Sensitive switch is a kind of quick converting switch of exerting pressure and actuating, because the contact spacing of its switch is smaller, so the name sensitive switch.Existing sensitive switch useful life is short, function and usage is single, needs artificial the triggering or control, and stress constantly changes, can not reliable and stable work, can not guarantee promptness, convenience and the harmony of switch.

The utility model content

The purpose of this utility model is to overcome the above-mentioned defective of existing sensitive switch, provide a kind of good stability, compact conformation, highly sensitive, rated current is big, electric life is long, applied widely, under action of gravity, can control switching automatically, the rotary triangle deadweight gate-controlled switch of the multi-faceted operate as normal of energy under dynamic rotating environment.

The technical solution of the utility model is: at shell is that columniform switch base inboard is distributed with three chamfered grooves, its middle part forms and is roughly leg-of-mutton space, a triangle is housed from the rotatable assembly of pouring weight in leg-of-mutton space, described triangle is to be made of a metal-cored corner block middle part that is embedded in from the rotatable assembly of pouring weight, three chamfered groove both sides at switch base are posted the conductive metal sheet that is connected with lead respectively, also post conductive metal sheet at triangle from the both sides, three angles of pouring weight.

Described three chamfered grooves become 120 ° evenly to distribute along switch base.

During use, under dynamic rotating environment when rotatable assembly during with 120 ° of extraneous carrier rotations, triangle falls from the pouring weight gravitate, contact with a left side or the upper right corner of switch base, the conductive metal sheet of triangle from the pouring weight place contacts with the conductive metal sheet at switch base place and makes the external circuitry conducting, the operate as normal of may command body.

The utility model has overcome existing sensitive switch needs artificial the triggering or control, and stress constantly changes, can not reliable and stable work, can not guarantee the defective of promptness, convenience and the harmony of switch; Can under action of gravity, control switching automatically, can have good stability in multi-faceted operate as normal under the dynamic rotating environment, compact conformation, highly sensitive, rated current is big, and electric life is long, advantage applied widely.

Fig. 2 is a switch-seat structure schematic diagram among Fig. 1;

Fig. 3 is that Fig. 1 intermediate cam is from the pouring weight schematic diagram.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment: with reference to accompanying drawing:

The switch base of present embodiment is to be distributed with three chamfered grooves 2 in the inboard of a cylinder 1, three chamfered grooves evenly distribute for 1 one-tenth 120 ° along cylinder, form in the middle and be roughly leg-of-mutton space, three chamfered groove both sides at switch base are posted the conductive metal sheet 4 that is connected with lead respectively, triangle are housed from the rotatable assembly of pouring weight in leg-of-mutton space.Triangle is embedded in the corner block 5 by one metal-cored 6 from the rotatable assembly of pouring weight, the corner block of present embodiment is that a surface is leg-of-mutton triangular prism, hollow out in the triangular prism center, hollow out the place and be cylinder, hollow out the place in the placement cylindrical metal-cored, also post conductive metal sheet 4 at triangle from the both sides, three angles of pouring weight.

Operation principle is: the metal-cored triangle that constitutes in the corner block that is embedded in falls from the pouring weight gravitate, contact with a left side or the upper right corner of switch base, triangle contacts with the sheet metal 4 at switch base place from the sheet metal 4 at pouring weight place, sheet metal is connected with lead, thereby make the external circuitry conducting, the operate as normal of may command body.

Claims

1. triangle deadweight gate-controlled switch, it is characterized in that, at shell is that columniform switch base inboard is distributed with three chamfered grooves, its middle part forms and is roughly leg-of-mutton space, a triangle is housed from the rotatable assembly of pouring weight in leg-of-mutton space, described triangle is to be made of a metal-cored corner block middle part that is embedded in from the rotatable assembly of pouring weight, three chamfered groove both sides at switch base are posted the conductive metal sheet that is connected with lead respectively, also post conductive metal sheet at triangle from the both sides, three angles of pouring weight.
