Abstract
The utility model discloses a straight gliding style electric tool switch, including handle, push rod and terminal box, the handle is connected with the push rod, its characterized in that: push rod upper end sets up ring groove, be equipped with in the terminal box with ring groove assorted locking piece, the pull rod is connected to the locking piece, the cover has the spring on the pull rod, the spring supports the locking piece, the push rod bottom is equipped with two moving contacts, the moving contact comprises movable contact and support, the terminal box bottom is equipped with first division board and second baffle, first division board top be equipped with two with moving contact assorted stationary contact, formation partition space bottom the second division board is equipped with the circuit board in. The structure of the utility model, simplified triggering element's structure, the sensitivity that can improve triggering element, double -layer partition board's design reduces the contact more effectively and generates heat to the harm of circuit board, improved circuit security, the life of extension switch.
Description
Technical field
This utility model relates to switch, is specifically related to a kind of direct slide electric tool switch.
Background technology
A lot of electric tool switch on the market, it touches original paper and is essentially a pair moving contact and static contact, moving contact is arranged in rosette, moving contact is generally made up of support, pendulum and movable contact, this kind of structure is generally mated push rod, in push rod pushing course, promote support motion thus realize contacting of movable contact and stationary contact, to realize being energized.But this structure typically requires push rod coordinates compression spring and the promotion of spheroid, and structure is complicated, and easily cause deformation of timbering because of abrasion in life-time service, affect the susceptiveness that movable contact contacts with stationary contact, thus affect the quality of electric tool switch.Meanwhile, general electric tool switch is not isolated between circuit board and other accessory, and trigger element in the energized state can heat production, the components and parts of circuit board be easily subject to damage or damage.
Summary of the invention
In view of the deficiency of background technology, technical problem to be solved in the utility model is to provide a kind of simple in construction, tool high sensitivity, high security and high-quality direct slide electric tool switch.
To this end, this utility model uses following scheme to realize:
A kind of direct slide electric tool switch, including hands handle, push rod and rosette, described handle is connected with described push rod, it is characterized in that: described push rod upper end arranges annular slot, the latch matched with described annular slot it is provided with in described rosette, described latch cylinder lever connecting rod, it is cased with spring on described pull bar, described spring props up latch, two moving contacts it are provided with bottom described push rod, described moving contact is made up of movable contact and support, the first division board and second partition it is provided with bottom described rosette, told the first division board and be arranged over two stationary contacts matched with moving contact, insulating space is formed bottom described second division board, it is provided with circuit board in described insulating space.
By using technique scheme, in use, by pressing push button, and then push directly on moving contact and move to stationary contact, and screens can be carried out specifying position thus realize contacting of movable contact and stationary contact, this design enormously simplify structure and the connected mode of trigger element, is effectively increased sensitivity and the degree of accuracy of electric tool switch, further increases the quality of electric tool switch.And the design of bilayer division board, thermal source is carried out significantly more efficient isolation, protection circuit plate, improves safety.
This utility model is further arranged to, and described every pair of movable contact being mutually matched is arranged on the same axis with described stationary contact.
By using technique scheme, it is possible to achieve movable contact effectively contacts with stationary contact, improves susceptiveness of the present utility model.
Accompanying drawing explanation
This utility model has a drawings described below:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of moving contact.
Detailed description of the invention
nullAs shown in the figure，A kind of direct slide electric tool switch disclosed in this utility model，Including handle 1、Push rod 2 and rosette 8，Described handle 1 is connected with described push rod 2，It is characterized in that: described push rod 2 upper end arranges annular slot 9，The latch 10 matched with described annular slot 9 it is provided with in described rosette 8，Described latch 10 cylinder lever connecting rod 12，In the present embodiment，Described pull bar 12 is L-shaped structure，It is cased with spring 11 on described pull bar 12，Spring 11 props up latch 10，Two moving contacts 3 it are provided with bottom described push rod 2，Described moving contact 3 is made up of movable contact 3b and support 3a，The first division board 5 and second partition 6 it is provided with bottom described rosette 8，Told the first division board 5 and be arranged over two stationary contacts 4 matched with movable contact 3b，Insulating space 7 is formed bottom described second division board 6，It is provided with circuit board in described insulating space 7.
The operation principle of the present embodiment is: in use, by lower handle 1, push rod 2 is promoted down to move, push rod 2 drives moving contact 3 to be synchronized with the movement, when the annular slot 9 on push rod 2 moves to the position of latch 10, snapping in ring lock draw-in groove 9 through the thrusting lock stops 10 of spring, now movable contact 3b realizes contacting with stationary contact 4, thus realizing energising, circuit is started working；When power cut-off, pulling out pull bar 12, handle of simultaneously pulling back, now, movable contact 3b separates with stationary contact 4, and circuit disconnects.In the present embodiment, the design of arrestment mechanism makes circuit more stable, can realize again high sensitivity, high security simultaneously.
Claims (2)
1. a direct slide electric tool switch, including hands handle, push rod and rosette, described handle is connected with described push rod, it is characterized in that: described push rod upper end arranges annular slot, the latch matched with described annular slot it is provided with in described rosette, described latch cylinder lever connecting rod, it is cased with spring on described pull bar, described spring props up latch, two moving contacts it are provided with bottom described push rod, described moving contact is made up of movable contact and support, the first division board and second partition it is provided with bottom described rosette, told the first division board and be arranged over two stationary contacts matched with moving contact, insulating space is formed bottom described second division board, it is provided with circuit board in described insulating space.
