Cylinder controls the reciprocating motion of cylinder by the time relay 11.
As a kind of embodiment, test fixture further includes more than two second driving devices 9, and two or more second is driven
Dynamic device 9 is set in parallel on holder 1, and the second driving device 9 is also electrically connected with the time relay 11, in the time relay 11
Control under, the second driving device 9 moves back and forth, and the second driving device 9 is used to abut the buttons of tested household electrical appliance, Mei Gesuo
It states button and corresponds to second driving device 9.Second driving device 9 is also cylinder, and the piston rod of cylinder is connected to tested household
When on the button of electric appliance, button is pressed, and after the piston rod of cylinder is retracted, button bounces automatically.To which test device can be used for
Test is tested the push button longevity of household electrical appliance.
As a kind of embodiment, test device further includes hoisting mechanism, and hoisting mechanism is arranged on holder 1, is used for
Lifting is tested household electrical appliance head.Hoisting mechanism includes supporting rack 4 and third driving device 8, one end of third driving device 8
(lower end) is fixed on holder 1, the first end (lower end) of the other end (upper end) the connection supporting rack 4 of third driving device 8, support
The second end (upper end) of frame 4 is moved for connecting tested household electrical appliance head, supporting rack 4 with 8 synchronous reciprocating of third driving device.
Third driving device 8 is also cylinder, and the head of tested household electrical appliance drives tested household electric during cylinder moves up and down
The lifting pipe of device moves up and down, so as to test the service life of lifting pipe.Certainly, other manner can also be used in hoisting mechanism
It realizes, for example, hoisting mechanism includes supporting rack 4, third driving device 8, gear 5, chain 6 and the second fixture 7,4 He of supporting rack
Third driving device 8 is arranged on holder 1, and gear 5 is arranged on supporting rack 4, and chain 6 is matched with gear 5, third driving

Stopper rod recycles, and by fan head toward pull-up, to make lifting pipe move upwards, unison counter counts automatically, so recycles.With
Upper three experiments are independent to be carried out.
The test device of above example, the time relay, cylinder and counter are combined, and gas is controlled in the time relay
(each independent progress of operation, every time experiment can only carry out a kind of behaviour for the lower automatic progress pitching of cylinder effect, lifting and button experiment
Make), when electric fan tests pitching, lifting and push-button service-life detection, the time relay often opens and closes primary counting once, while can
Voluntarily reach setting number and be automatically stopped experiment, is kept an eye on side without personnel in whole experiment process.It ensure that in experimentation
Dynamics, the consistency of speed improve working efficiency, achieve the purpose that control person's synergy.According to wanting for different ground electric fans design
It asks, changes cylinder height, test speed can also be changed and so that meeting different size electric fan carries out pitch angle life experiment, rises
Pipe lifting life experiment, the work of driving switch push button longevity are dropped.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
