Abstract
The utility model discloses a novel keyboard detection device which comprises an electromagnetic valve. A top end of a movable iron core of the electromagnetic valve is provided with a spring. The movable iron core is extended out from a lower end of the electromagnetic valve. The movable iron core is movably inserted into a weight from the top of the weight. An upper end of the weight is provided with a square hole. At the square hole of the weight, the movable iron core is inserted with a bolt which limits the movement travel of the weight. The novel keyboard detection device has the advantages of reasonable structure and artful design, when the electromagnetic valve is energized, the weight overcomes the spring to carry out freely falling body motion, keys of a keyboard are tested, when the electromagnetic valve is not energized, the spring overcomes the weight of the weight, and the weight is reset. The novel keyboard detection device has the advantages of convenient use, accurate testing, precise displacement, and improvement of service life and service quality.
Description
Technical field
The utility model belongs to Electron YuanJianJianCeZhuangZhi, particularly a kind of novel keyboard pick-up unit that detects keyboard.
Background technology
Keyboard be the most frequently used also be topmost input equipment in the computer system, by beaing button on the keyboard contact conducting is disconnected, thereby letter, numeral, punctuation mark etc. is input in the computing machine.During keyboard is produced at present, when finished product is carried out quality testing, need to impact each button, test the break-make of its resilience and contact, dynamics is moderate when impacting, and it is consistent that stroke is wanted, and the application of force and the power of removing will be finished in moment.
Special Equipment is realized the keyboard detecting device of this operation at present, comprise columnar metal shell and be arranged on the electromagnet that is consisted of by coil and armature in the metal shell, the part that armature exposes the metal shell top is equipped with back-moving spring, the part of exposing the metal shell bottom is provided with contact, produce magnetic field around when electromagnet is switched on, the armature end face adhesive with metal shell that is magnetized, the band moving contact down moves, impact button, armature resets under action of reset spring during outage, and so forth the button of keyboard is knocked detection.The contact moving displacement of this keyboard detecting device is relevant with additional power source, and when voltage was excessive or too small, deviation just appearred in the displacement of contact, in use exists simultaneously also to have the excessive defective of noise.
The utility model content
The purpose of this utility model is, the purpose of this utility model is to provide a kind of defects that overcomes, displacement precisely, the novel keyboard pick-up unit that is improved of serviceable life and service property (quality).
The technical scheme that the utility model adopts for achieving the above object is:
A kind of novel keyboard pick-up unit, it comprises a solenoid valve, the movable core top of this solenoid valve is provided with a spring, this movable core is stretched out by the lower end of this solenoid valve, this movable core is inserted in this counterweight movably by the top of a counterweight, the upper end of this counterweight is provided with a square opening, and this movable core is inserted with a latch that limits this counterweight shift motion in the square opening position of described counterweight.
The top of this solenoid valve is stretched out on the top of described movable core, and this spring housing places on this movable core, and the top of this spring is provided with a POM pad and a jump ring successively.
The end of described counterweight is provided with a contact.
Counterweight weight is the weight of the freely falling body of test keyboard.
The length of the position of pin-and-hole, spring determines the movement travel of counterweight on the length of the square opening of counterweight and the movable core!
The design of pin-and-hole is screens design on the movable core, cooperates the easy disassembly counterweight between this pin-and-hole and the latch.
Pin-and-hole position on the movable core, a stroke of restriction counterweight motion! When counterweight carries out the movement of falling object, when touching this and being inserted in pin on this pin-and-hole, namely stopped movement.
The weight of counterweight needs and the spring coupling, the stroke of motion and the length of spring and pin location matches,
The beneficial effects of the utility model are: the utility model is rational in infrastructure, designs ingeniously, and solenoid valve when energising counterweight overcomes spring and carries out the movement of falling object, the test keyboard, spring overcoming counterweight weight during the solenoid valve outage so that counterweight reset.The utility model is easy to use, test accurately, displacement is precisely, serviceable life and service property (quality) be improved.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment: see Fig. 1, a kind of novel keyboard pick-up unit of the utility model, it comprises a solenoid valve 1, movable core 3 tops of this solenoid valve 1 are provided with a spring 2, this movable core 3 is stretched out by the lower end of this solenoid valve 1, this movable core 3 is inserted in this counterweight 4 movably by the top of a counterweight 4, and the upper end of this counterweight 4 is provided with a square opening 41, and this movable core 3 is inserted with a latch 5 that limits these counterweight 4 shift motions in square opening 41 positions of described counterweight 4.
The top of this solenoid valve 1 is stretched out on the top of described movable core 3, and this spring 2 is placed on this movable core 3, and the top of this spring 2 is provided with a POM pad 7 and a jump ring 8 successively.
The end of described counterweight 4 is provided with a contact 9.
Counterweight 4 weight are the weight of the freely falling body of test keyboard.
The length of the position of pin-and-hole, spring 2 determines the movement travel of counterweight 4 on the length of the square opening 41 of counterweight 4 and the movable core 3!
The design of pin-and-hole is screens design on the movable core 3, cooperates easy disassembly counterweight 4 between this pin-and-hole and the latch 5.
Pin-and-hole position on the movable core 3, a stroke of restriction counterweight 4 motions! When counterweight 4 carries out the movement of falling object, when touching this and being inserted in pin on this pin-and-hole, namely stopped movement.
The weight of counterweight 4 needs and spring 2 couplings, the length of the stroke of motion and spring 2 and pin location matches,
The utility model is rational in infrastructure, designs ingeniously, and counterweight 4 overcomes spring 2 and carries out the movement of falling object during solenoid valve 1 energising, the test keyboard, and spring 2 overcomes counterweight 4 weight so that counterweight 4 resets during solenoid valve 1 outage.The utility model is easy to use, test accurately, displacement is precisely, serviceable life and service property (quality) be improved.
As described in the utility model embodiment, with other novel keyboard pick-up units of the same or similar structure of the utility model, all in the utility model protection domain.
