Abstract

A wiring switch is provided, which has a simplified structure and a reduced production cost. The switch is characterized in that a rotating shaft perpendicular to the bottom surface is formed on the bottom surface of a base, and an insulating rotating wheel with an inclined clamp and an inclined plane notch is sleeved on the rotating shaft to rotate in a single direction, so that a metal sheet connected with an external wire in the switch is separated or contacted, and the circuit in the switch is disconnected or connected.

Description

A kind of pulling switch

Affiliated technical field

The utility model relates to a kind of pulling switch

Background technology

At present, known pulling switch is made up of base, terminal block, axle, moving runner, garden dish pull bar, spring, jump ring etc.Because rotation axis is parallel with base end face, so cause whole construction of switch numerous and diverse, part is many, production, assembly cost height, and volume is big.

Summary of the invention

The utility model provides a kind of pulling switch, and this switch has been simplified internal structure, makes smaller volume, and production, assembly cost reduce.

The technical method that its technical problem that solves the utility model adopts is: on base end face, make one with the bottom surface be 70 to 110 the degree angles rotation axiss, utilize the one-directional rotation of the insulation moving runner of an oblique card of band and inclined-plane breach, make the sheet metal in the switch produce separation or contact, thereby finish the open close of the interior circuit of switch.

The beneficial effects of the utility model are: the switch internal structure is reduced, and volume reduces, and production cost reduces.

Embodiment

In Fig. 1, vertical axis [2] and shelves post [3], screw hole [4] are arranged on the bottom surface of base [1], the oval moving runner [7] that band is cambered outwards oblique card of triangle rib [5] and inclined-plane breach [6] is enclosed within on the vertical axis [2], two metal clipss [8], [9] middle part are fixed on the fixed leg [10], one end forms the electric wire folder with base side wall [11] respectively, have two electric wires [13] to enter hole [12] on the sidewall [11], shell fragment [8] other end reaches on the shell fragment [9], does not press mutually when being subjected to external force.Spring [15] one ends are fixed in vertical axis [2], and an end is connected with backguy [17] after [5] make pull bar [16] through tiltedly blocking.After pulling backguy [17], pull bar [16] rotates oval moving runner [7] by oblique card [5], snaps in next inclined-plane breach [6] to uvula card [14], decontrols backguy [17], and pull bar [16] snaps in next oblique block [5] under self elastic force effect.When the major axis minor axis of oval moving runner [7] alternately was pressed on shell fragment [8], shell fragment [8] separated with shell fragment [9] or contacts, and circuit disconnects or connects.Lid [18] can pass through inserted sheet [19] and insert in the sidewall [11], makes two little protruding [20] on the lid [18] for conveniently extracting, and also can connect by spiral.

In second embodiment shown in Figure 4, the trident sheet metal [23] of three equidistant tongue pieces of a slice band [21] and 1 circular hole [22], the insulation slewing circle wheel [24] that one band tiltedly blocks [5] and 6 inclined-plane breach [6] successively is placed on the vertical axis [2], tongue piece [21] is gone up folding and is stuck in three inclined-plane breach [6] of being separated by on the circle wheel [24], in metal clips [25], [26] the middle part difference fixed legs [10], an end forms the electric wire folder with sidewall [11] respectively; The other end is respectively along pressing and withstanding one the inclined-plane breach [6] of being separated by, and both made the circle wheel [24] can only one-directional rotation.And touch mutually simultaneously with tongue piece [21] or from, thereby reach the break-make of control circuit.

Claims (5)
