Abstract
The utility model relates to a switch for electric tools, comprising a press-button, a push rod, a plastic base, moving contacts and springs arranged at the upside and downside of the plastic base; one end of the upside spring is fixedly connected with the upside moving contact, one end of the downside spring is fixedly connected with the downside moving contact. A cavity is arranged in the plastic base, the push rod capable of sliding upwards and downwards is arrange inside the cavity, a upside metal coupon and a downside metal coupon are fixed on lateral face of the inner wall of the push rod, the upside metal coupon and the downside metal coupon are respectively provided with a upside fixed column and a downside fixed column, the other end of the upside spring is fixed on the upside fixed column and the other side of the downside spring is fixed on the downside fixed column. The utility model has the advantages that the fixed column of metal material replaces the prior fixed column of plastic material, the fixed column of metal material has great resistance to abrasion when the switch is used; since the problems of abrasion is excluded, spring with relatively larger elasticity can be selected which can improve the operation sensitivity of the switch.
Description
Technical field
The utility model relates to a kind of switch, particularly a kind of electric tool switch.
Background technology
Electric tool switch of the prior art generally comprises push rod, plastic base, plastic base is provided with cavity, one side inwall of plastic base is provided with the upper and lower sides plastics fixed leg that is structure as a whole with plastic base, generally be in the injection moulding of plastic base, directly to form, push rod is slidably located on up and down in the cavity of plastic base, also comprise the upper and lower sides moving contact in the plastic base, the upper and lower sides spring, one end of upside spring is fixedlyed connected with the upside moving contact, the other end is fixedlyed connected with the upside moving contact, one end of downside spring is fixedlyed connected with the downside moving contact, and the other end is fixedlyed connected with the downside moving contact.The shortcoming that the electric tool switch of said structure exists is: because spring is fixed on the plastics fixed leg, because wear and tear, the time one is long, phenomenon of rupture can occur, has influenced the useful life of switch in the switch use for the plastics fixed leg; In order to reduce wear, the elastic force of the spring that uses is generally smaller, so the action of switch is sensitive inadequately.
Summary of the invention
In order to solve the shortcoming of above-mentioned electric tool switch, the utility model provides the electric tool switch of a kind of long service life, switch work sensitivity.
Technical solution of the present utility model provides a kind of electric tool switch, comprise button, push rod, upside moving contact in plastic base and the plastic base, the downside moving contact, the upside spring, the downside spring, one end of upside spring is fixedlyed connected with the upside moving contact, one end of downside spring is fixedlyed connected with the downside moving contact, be provided with cavity in the plastic base, push rod is slidably mounted in the cavity, be fixed with upside sheet metal and downside sheet metal on the inwall side of described push rod, be respectively equipped with upside fixed leg and downside fixed leg on upside sheet metal and the downside sheet metal, the upside spring other end is fixed in the upside fixed leg, and the downside spring other end is fixed in the downside fixed leg.
Because in the above-mentioned technical solution, be fixed with upside sheet metal and downside sheet metal on the inwall side of push rod, sheet metal is respectively equipped with fixed leg, spring is fixed on the fixed leg of sheet metal, the fixed leg of employing metal material has replaced the plastics fixed leg of prior art, the fixed leg of metal material is very wear-resistant in the switch use, so useful life of having improved switch greatly, more owing to need not consider wear problem, the spring that uses can be selected bigger elastic force, therefore can improve the action sensitivity of switch.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Extremely shown in Figure 8 as Fig. 1, the embodiment of the utility model electric tool switch, comprise button 1, push rod 3, plastic base 4, be provided with cavity 2 in the plastic base 4, push rod 3 is installed in the cavity 2, push rod 3 can slide up and down in cavity 2, also be provided with upside moving contact 5 in the plastic base 4, downside moving contact 6, upside spring 7, downside spring 8, one end of upside spring 7 is fixedlyed connected with upside moving contact 5, one end of downside spring 8 is fixedlyed connected with downside moving contact 6, be fixed with upside sheet metal 9 and downside sheet metal 10 on the right flank of the inwall of push rod 3, the upside sheet metal is respectively equipped with upper hem 13 and lower hem 14 in two ends about in the of 9, the upper hem 13 of upside sheet metal 9 and lower hem 14 embed push rod 3 upper inside wall respectively, the downside sheet metal is respectively equipped with upper hem 15 and lower hem 16 in two ends about in the of 10, the upper hem 15 of downside sheet metal 10 and lower hem 16 embed push rod 3 inwall bottoms respectively, also be respectively equipped with upside fixed leg 11 and downside fixed leg 12 on upside sheet metal 9 and the downside sheet metal 10, upside spring 7 other ends are fixed in upside fixed leg 11, and downside spring 8 other ends are fixed in downside fixed leg 12.
In order to improve the sensitivity of electric tool switch, described upside sheet metal 9 is provided with horizontal raised line 17, upside fixed leg 11 is arranged on the horizontal raised line 17 of upside sheet metal 9, described downside sheet metal 10 is provided with horizontal raised line 18, and downside fixed leg 12 is arranged on the horizontal raised line 18 of upside sheet metal 10.Owing to be provided with horizontal raised line, laterally raised line just becomes the fulcrum of spring, and stroke shortens by fixedly becoming horizontal fixed up and down for spring fixing, and the spring time of staying shortens, thereby has improved the sensitivity of switch.
The upside sheet metal 9 and the downside sheet metal 10 of the push rod 3 among the embodiment of the present utility model are arranged in a linear on the vertical direction of the right flank of inwall, and the upside fixed leg 11 of upside sheet metal 9 also is arranged in a linear on the vertical direction of the right flank of inwall with the downside fixed leg 12 of downside sheet metal 10.The so just feasible spring process that is connected to the upper and lower sides spring of upside fixed leg 11 and downside fixed leg 12 becomes and very one makes peace accurately the sensitivity that has improved electric tool switch further.
