Abstract
The invention discloses a keyboard striking rod, which is characterized by comprising an electromagnet and a counterweight rod, wherein an electromagnetic spool is arranged on the electromagnet, the electromagnetic spool is connected with the counterweight rod through a center hole on the counterweight rod and can move back and forth in the center hole of the counterweight rod; the counterweight rod consists of a counterweight block connector and a counterweight block which are fixedly connected with each other through threads; the center hole is a stepped hole; a limiting nut for preventing the electromagnetic spool from falling off from the counterweight rod is arranged at the end of the electromagnetic spool through the center hole; process holes are arranged on the counterweight block connector and the counterweight block; and a rubber head is arranged at the end of the counterweight block. The keyboard striking rod has the advantages that the striking detection of keyboards in different kinds can be realized, the striking force is effectively ensured, the safety of the keyboard is ensured, the labor cost is reduced and the production efficiency is improved.
Description
Technical field:
The present invention and a kind of bar that knocks, especially a kind of keyboard knocks bar.
Background technology:
Along with constantly popularizing of computer, the production of computer fittings also quantizes gradually, especially computor-keyboard; Usually, computor-keyboard all will carry out keyboard and knock test after end is installed, measure the keyboard quality; Early stage keyboard test all is through manual work; But this metering system is more time-consuming, take the labour, inefficiency, but bar is knocked in the present most employing of keyboard test firmly; This bar that knocks knocks data with power etc. and must set between knocking; It is constant to be used to knock pole length, therefore slightly just neglects sometimes and easily keyboard is broken, and causes unnecessary loss.
Summary of the invention:
Technical matters to be solved by this invention provides a kind of elastic reaction that has, and guarantees that effectively a kind of keyboard of percussion power knocks bar.
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme:
This keyboard knocks bar and comprises electromagnet and weight linear meter, and said electromagnet is provided with electromagnetic valve core, and electromagnetic valve core is connected with weight linear meter through the center pit that is arranged on the weight linear meter, and electromagnetic valve core can move around in the center pit of weight linear meter.Electromagnet energising rear electromagnetic valve core moves down, and sliding bar glides at the action of gravity lower edge spool of breeding piece, knocks keyboard; After the electromagnet outage; Electromagnetic valve core returns, and returns through the limit screw cap drive sliding bar of electromagnetic valve core termination, and then moves on the drive balancing weight.
In order to connect different balancing weights, further, said weight linear meter is made up of balancing weight connector and balancing weight, is fixedly connected through screw thread.
For electromagnetic valve core is packed in the center pit, further, said center pit is a shoulder hole.
In order to prevent that electromagnetic valve core and weight linear meter break away from, further, said electromagnetic valve core is provided with the limit screw cap that prevents electromagnetic valve core slippage in the weight linear meter through center pit in the termination.
For ease balancing weight is disassembled or install balancing weight from sliding bar, further, said sliding bar and balancing weight are provided with fabrication hole.
For prevent the balancing weight termination really up to the mark with keyboard hit the flower or grind away, the end of said balancing weight is provided with rubber tip.
Compared with prior art, usefulness of the present invention is: this device can realize that different types of keyboard knocks detection, guarantees the dynamics of knocking effectively, guarantees the safety of keyboard, has reduced cost of labor simultaneously, has improved production efficiency.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the full sectional view of Fig. 1.
Among the figure: 1, electromagnet; 2, weight linear meter; 2-1, balancing weight connector; 2-2, balancing weight;
3, center pit; 4, electromagnetic valve core; 5, limit screw cap; 6, fabrication hole;
7, rubber tip.
Embodiment:
Describe the present invention below in conjunction with accompanying drawing and embodiment:
Fig. 1, a kind of keyboard shown in Figure 2 knock bar, comprise electromagnet 1, and electromagnet 1 is provided with electromagnetic valve core 4, and after electromagnet 1 energising, electromagnetic valve core 4 can be up and down on electromagnet 1; Said electromagnet 1 is connected with weight linear meter 2 through electromagnetic valve core 4; Be provided with center pit 3 in the middle of the said weight linear meter 2; Said center pit 3 is a shoulder hole; Be made up of an aperture and a macropore, the termination of electromagnetic valve core 4 is connected with the interior limit screw cap 5 of macropore through the aperture in the center pit 3, and electromagnet 1 and sliding bar 2 are linked together; And electromagnetic valve core 4 can move around in the center pit 3, and limit screw cap 5 can prevent electromagnetic valve core 4 and weight linear meter 2 disengagements; Said weight linear meter 2 is made up of balancing weight connector 2-1 and balancing weight 2-2, between be fixedly connected through screw thread; Be equipped with fabrication hole 6 on balancing weight connector 2-1 and the balancing weight 2-2, can make things convenient for balancing weight 2-2 to disassemble, change, to adapt to different types of computor-keyboard through fabrication hole 6; The end of said balancing weight 2-2 is provided with rubber tip 7, can prevent that through rubber tip 7 keyboard from knocking bar and when knocking keyboard, the key face being scratched or break, and guarantees the safety of keyboard.
Its working method is following: according to the quantity of keyboard, keyboard is knocked bar be installed to keyboard and knock on the machine, and weight linear meter 2 terminal rubber tip 7 are knocked the interface with keyboard certain distance need be arranged; After electromagnet 1 energising, electromagnetic valve core 4 moves down, and this moment, balancing weight connector 2-1 glided under the action of gravity of balancing weight 1-2 drives, and keyboard is knocked check.Owing to can slide each other between weight linear meter 2 and the electromagnetic valve core 4, therefore, even when weight linear meter 2 terminal distances with the keyboard key face are too small, weight linear meter 2 still is on the keyboard that knocks with same dynamics; After electromagnet 1 outage, electromagnetic valve core 4 returns, because the effect of electromagnetic valve core 4 termination limit screw caps 5, weight linear meter 2 also returns thereupon, leaves key panel, accomplishes and detects.Balancing weight 2-2 can change according to keyboard classes on the said weight linear meter 2; When detecting keyboard of notebook computer; The balance weight iron 2-2 of 73-75 gram can be changed into, when detecting desktop keyboard, the balance weight iron 2-2 of 85 grams can be changed into; Guarantee the enough weight of knocking, can guarantee the security of keyboard again.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
