Abstract
The utility model belongs to the technical field of electrical elements and in particular relates to a cord switch. The cord switch comprises a base as well as a ratchet wheel, a driving wheel iron sheet, a reset spring, a rotating shaft, copper conductive sheets and a cord wire, which are arranged in a groove of the base, wherein each conductive sheet is arranged on the ratchet wheel every other one pawl, the reset spring is fixedly provided with a reset hole in an extending manner, and one end of the cord wire is fixed and passes through the reset hole. The cord switch is characterized in that a cushion plastic ring is arranged in the reset hole, and a plastic sleeve is sleeved on the cord wire passing through the reset hole. According to the cord switch, through the design, the friction force between the cord wire and the reset hole can be greatly reduced, therefore the problem that the cord wire is easy to break is solved and the service life of the cord switch is prolonged.
Description
Technical field
The utility model belongs to the electric elements technical field, is specifically related to a kind of pulling switch.
Background technology
Common pulling switch comprises base, and the ratchet that is provided with in bottom tub, the thumb wheel iron plate, back-moving spring, rotating shaft, conductive copper sheet and backguy, be provided with a conducting strip every a ratchet on the ratchet, rotating shaft is connected with the thumb wheel iron plate, back-moving spring is fixed on the rotating shaft and with the thumb wheel iron plate and is connected, and back-moving spring is provided with the copper sheet reset hole, this reset hole is fixed and passed to backguy one end, by the pulling backguy, can rotate back-moving spring, thereby ratchet is rotated, when the conducting strip that is crisscross arranged on the click with after conductive copper sheet contacts, turning circuit, open circuit then when not having conducting strip on the ratchet.
Because this pulling switch is in switching process, the backguy meeting rubs with reset hole, this direct friction makes backguy easily broken especially, change and bother especially, especially in the rural area, this pulling switch uses quite general, and such shortcoming will inevitably have influence on daily life, therefore we need design and a kind ofly can reduce frictional force, prolong the pulling switch in backguy life-span.
Summary of the invention
At above shortcomings in the prior art, the utility model provides a kind of durable pulling switch.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of pulling switch, comprise base, and the ratchet, thumb wheel iron plate, back-moving spring, rotating shaft, conductive copper sheet and the backguy that are provided with in bottom tub, be provided with a conducting strip every a ratchet on the ratchet, fixing and extend a reset hole on the described back-moving spring, this reset hole is fixed and passed to described backguy one end, is provided with the cushion plastic hoop in the reset hole, and pass near the reset hole the backguy and be with plastic bushing.
Adopt the pulling switch of technique scheme, by the cushion plastic hoop is set on reset hole, can reduce the frictional force between backguy and the reset hole effectively, solve the easily broken problem of backguy, put plastic bushing near the reset hole backguy simultaneously and further reduce frictional force.
Furthermore, described plastic hoop is greater than rightabout at the thickness of backguy and reset hole action direction.This be because backguy frequently when pulled, thereby it drives ratchet and rotates by pressing down reset hole, therefore the direction of backguy and reset hole effect can be provided with thicker, and that stressed opposite direction can be provided with is more thinner.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model reset hole structural representation.
Embodiment
In order to make those skilled in the art understand the utility model better, technical solutions of the utility model are further specified below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, a kind of pulling switch, comprise base 1, and the ratchet 2, thumb wheel iron plate 3, back-moving spring 4, rotating shaft 5, conductive copper sheet 6 and the backguy 8 that are provided with in bottom tub, be provided with a conducting strip 7 every a ratchet on the ratchet 2, fixing and extend a reset hole 9 on the described back-moving spring 4, this reset hole 9 is fixed and passed to described backguy 8 one ends, be provided with cushion plastic hoop 10 in the reset hole 9, and pass near the reset hole 9 the backguy 8 and be with plastic bushing 11.
Cushion plastic hoop 10 is set on the described reset hole 9 can reduces frictional force between backguy 8 and the reset hole 9 effectively, solve the easily broken problem of backguy, near the backguys 8 the reset hole 9 simultaneously put plastic bushing 11 and further reduce frictional force.
When considering that backguy 8 interacts with reset hole 9, its action direction presses down direction along reset hole 9, also be the direction of rotation of ratchet 2, thus plastic hoop backguy 8 and reset hole 9 action directions can be provided with thicker, what then can be provided with in the other direction is more thinner.
Show by experiment: common switch can spur about 1500 times and will break, if spur 10 calculating average every day, the backguy pulling will be broken in about 150 days, so backguy has only the useful life of nearly half a year.And the pulling switch of employing technical solutions of the utility model, backguy can spur about 6500 times, if average every day is still to spur 10 calculating, backguy can spur 650 talentes and can break, therefore prolonged more than 300% the useful life of backguy, improve the useful life of backguy greatly, avoided changing the trouble that backguy brought.
The utility model is by being provided with the cushion plastic hoop in reset hole, pass near the backguy of reset hole and put plastic bushing, can be so that hard friction changes soft friction into, can reduce the frictional force between backguy and the copper sheet reset hole greatly, solve the easily broken problem of backguy, thereby improve the useful life of backguy.
More than pulling switch that the utility model is provided be described in detail.The explanation of specific embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection range of the utility model claim.
Claims (2)
1. pulling switch, comprise base, and the ratchet, thumb wheel iron plate, back-moving spring, rotating shaft, conductive copper sheet and the backguy that are provided with in bottom tub, be provided with a conducting strip every a ratchet on the ratchet, fixing and extend a reset hole on the described back-moving spring, this reset hole is fixed and passed to described backguy one end, it is characterized in that, be provided with the cushion plastic hoop in the reset hole, and pass near the reset hole the backguy and be with plastic bushing.
2. a kind of pulling switch according to claim 1 is characterized in that, described plastic hoop is greater than rightabout at the thickness of backguy and reset hole action direction.
