Abstract

Provided is an angle switch, including an angle displacement setting frame, a swinging axis, a swinging body, an electrode. The utility model working principle is that the angle displacement setting frame is installed on the axis base of the device needing to be controlled via the two ends of the swinging axis, the angle displacement setting frame or the handle is rotated anticlockwise with a certain angle, so the device clockwise rotates a certain angle to make the swinging body rotate anticlockwise by the gravity to contact the electrode, so as to close the switch. So people can randomly set a plurality of inclined angles which the device allows in a certain range by the angle displacement setting frame or the handle. The utility model has the advantages that the switch is not provided with mercury, so as to prevent environmental pollution, the utility model saves the useless structure, and is low in production cost, high in stability, long in service life.

Description

A kind of angle switch

This use is novel to belong to switch motion when the angle of object and plumb line reaches certain angle in the certain angle scope, the switch of angle initialization and angle identification just.

Now disclosed Sitting posture correcting device angle sensor element generally adopts the mercury sensing element, as 93247912.X and No. 93202588.9 Patent publish.Also having a kind of is metal pendulum mass angular displacement touch switch, as No. 002151316 Patent publish.The former is because of using mercury, as large-scale popularization, spend the several years after serious environment pollution, the latter only considers in addition that because of balance staff is difficult for the extraction electrode lead-in wire in little axle and because of balance staff is very thin the angular displacement fixed support Mold Making of single structure is not easy.When reaching certain angle with the angle of plumb line in the certain angle scope, this device also needs to send signal at the device in some other field, so that control effectively.

The novel purpose of this use is a kind of switch that provides in order to address the above problem.

A kind of angle switch, it comprises the angular displacement fixed support, balance staff, pendulum mass, electrode, the outside is exposed in two terminations of balance staff during with balance staff splice angle displacement fixed support and pendulum mass.

On the angular displacement fixed support, protrusion is set on the electrode opposite.

Handle outwards is set on the angular displacement fixed support.

The angular displacement fixed support adopts the closed loop frame, the balance staff hole is set in the middle of this closed loop frame, this balance staff pore geometry axis and decreased food direction are perpendicular, horizontal string pendulum mass of balance staff and string are on the balance staff hole, along the balance staff direction projecting surface is set on this closed loop frame, this projecting surface lower end is provided with circular hole, and this circular hole links to each other with the balance staff hole is coaxial.

Cross on the opposite of protruding on the closed loop frame of pendulum mass electrode be set, pendulum mass on its electrode under the vertical state a bit or a geometrical edge just to contact with pendulum mass.

The angular displacement fixed support adopts the open loop frame, the balance staff hole is set in the middle of this open loop frame, this balance staff pore geometry axis and decreased food direction are perpendicular, horizontal string pendulum mass of balance staff and string are on the balance staff hole, inboard by pendulum mass on this open loop frame is provided with projecting surface along the balance staff direction, and the circular hole that is provided with on this projecting surface links to each other with the balance staff hole is coaxial.

Cross on the opposite of protruding on the open loop frame of pendulum mass electrode be set, pendulum mass on its electrode under the vertical state a bit or a geometrical edge just to contact with pendulum mass.

Protrude and be variable-length protrusion or regular length protrusion.

One end of balance staff is provided with the balance staff head thicker than balance staff, on the balance staff head translot is set.

Electrode is for conduction bar type or conduction chip or conduct electricity matrix formula or spring cassette.

This use novel advantage be because of not adopting mercoid switch not have any environmental pollution, Mold Making is simple, assembling easily.

Further specify the utility model below by the embodiment drawings and Examples.

Fig. 1 is the front view of this use new embodiment one.

Fig. 2 is the vertical view of this use new embodiment one.

Fig. 3 is the front view of this use new embodiment two.

Fig. 4 is the vertical view of this use new embodiment two.

Angular displacement fixed support in the present embodiment protrudes 6, projecting surface 8, projecting surface 12, handle 5, but single injection-molded.As the angular displacement fixed support is the open loop frame, during Mold Making because of being easier to without the side core-pulling ratio.Balance staff 1, pendulum mass 2, electrode 4 is made by machine work and punch forming.

Balance staff 1 is also very thin when the device of needs control is very little, is not easy so pick out electrode wires from bar-shaped balance staff 1.So the little axle that discloses on No. 002151316 patent is removed, balance staff 1 is worked as little axle and directly is contained in by on the axle bed of empty device, and the balance staff head 9 thicker than balance staff 1 is set in an end of balance staff 1, translot 10 is set on balance staff head 9, put thin electric wire and weld out electrode on translot 10, so promptly convenient the installation do not influence performance again.

Protrude 6 with electrode 4 between the big more pendulum mass 2 in gap to turn the big more collision sound that may occur of angle around balance staff 1 also big more, regulate the gap and can reduce to collide sound so protrude 6 screws.

This angle switch is contained in balance staff 1 two ends on the axle bed that needs control device, and makes handle 5 and need control device closely to contact to make enough frictional resistances are arranged between them.With this understanding as Fig. 1, the angular displacement fixed support is rotated counterclockwise certain angle around balance staff 1, then this device rotates certain angle in the direction of the clock pendulum mass 2 is rotated counterclockwise by its gravity relative angular displacement fixed support, pendulum mass 2 contacts with electrode 4 balance staff 1 and electrode 4 is connected by pendulum mass 2, realizes switch closure.Allow the angle of inclination so can arbitrarily set some devices within the specific limits by handle 5.
