Abstract
The invention relates to a trigger gear of a scanner. A trigger structure with independently-replaceable elastic washers is adopted to realize an optimal ergonomic design, so that the good user experience is provided, the service life of the trigger structure is prolonged, and the lowest cost is kept at the same time of easy replacement. The trigger gear comprises a trigger and button switches, wherein the elastic washers and washer supports which are independent mutually and assembled movably are arranged between the trigger and the button switches; the washer supports are equipped with a limiting device respectively; the elastic washers are movably installed on the limiting devices; button trigger devices which are coordinated mutually are arranged on the trigger and the elastic washers; and the button trigger devices and the button switches are contacted or separated, so that the button switches are triggered.
Description
Technical field
The present invention relates to a kind of scanner trigger gear.
Background technology
Gun-type bar code scanner in the market or similar gun shaped product all need a trigger configuration to press the button usually, trigger scanner or similar products work.In the design of most gun-type product, trigger and button directly contact, and do not have elasticity middleware to connect.Owing to having mismatch error between trigger and button, between trigger and button, certain gap may be left, such trigger need certain stroke after could and button contacts.In addition also have a kind of may, be interference fit between trigger and button, namely before finger buckle trigger action, trigger and button have had and have contacted.Under both of these case, the feel of cocking is all very poor, and finger is easily tired.
For this reason, inside the cocking mechanism of the product that existing market has, added an elastomeric pad between trigger and button, this elastomeric pad and a pad support are integrated.Although this structure can solve the problem of feel, its shortcoming is that elastomeric pad can not be replaced separately.If need displacement, must replace together with pad support.Meanwhile, the structure that this elastomeric pad and pad support are integrated also is not easy to processing, and processing cost is also high.
From ergonomics angle, the trigger that Long-Time Service elasticity is larger, is easy to produce fatigue.If women uses trigger, the trigger product that elasticity is little can be selected, Long-Time Service can be avoided to hold fatigable problem.If the male sex uses trigger, the trigger product that elasticity is large can be selected, the active force on push-button switch can be avoided excessive and reduce life-span of trigger/button.From the market demand, what meet ergonomic designs has excellent handle and adopts the product of different DE more can obtain the favor of user according to different user.Obvious existing product can not meet this market demand.
Summary of the invention
Object of the present invention is exactly for solving the problem, a kind of scanner trigger gear is provided, it adopts the trigger configuration of independent replaceable elastomeric pad to realize better Ergonomics design, while bringing better experience to user, also the useful life of trigger configuration can be extended, be easy to change while characteristic possessing, also keep minimum cost.
For achieving the above object, the present invention adopts following technical scheme:
A kind of scanner trigger gear, it comprises trigger and push-button switch, described trigger and the elastomeric pad be provided with between push-button switch together with separate and Moveable assembled and pad support, described pad support is provided with stopping means, and elastomeric pad is movably arranged on stopping means; Trigger and elastomeric pad are provided with the button trigger equipment matched, and button trigger equipment contacts with push-button switch or is separated thus trigger button switch.
Described stopping means is the T-shaped hole on pad support, and match with elastomeric pad size in the aperture in T-shaped hole, elastomeric pad is movably arranged in T-shaped hole.
The groove that described button trigger equipment comprises a projection on trigger and matches with this projection on elastomeric pad, notch end contacts with push-button switch.
Described protruding circle of position post.
The present invention forms primarily of 4 parts: trigger, elastomeric pad, pad support and push-button switch.Mounting means in their each comfortable gun-type scanners is same as the prior art, repeats no more the concrete syndeton of they and gun-type scanner.
Elastomeric pad is placed in the T-shaped hole of pad support, and T-shaped hole can limit the movement up and down of elastomeric pad, and restriction is toward the movement of push-button switch.Trigger has a small column, be just in time assemblied in interchangeable elastomeric pad, can limit elastomeric pad and escape from, push-button switch is fixing on a printed circuit.When the masterpiece pointed is used for trigger time, elastomeric pad can play the effect of buffering, and the impact directly acted on push-button switch decreases, and can protect push-button switch.The bounce of push-button switch is less, adds the bounce of elastomeric pad, the bounce that on finger, common sensation arrives, than much smooth and easy when not having an elastomeric pad.Such feel is just all well and good.Elastomeric pad is made up of soft plastic, and the elastomeric pad of different hardness just has different elasticity, just can produce different flexible elastomeric pad, so just have the trigger gear of different feels.The elastomeric pad that elasticity is large, goes for the crowd that strength is large, as occidentals, or the male sex, elastomeric pad is little, goes for the crowd that strength is little, as asian population, or women.
When needs different elastomeric pad time, as long as take trigger apart, put into the elastomeric pad wanted just passable, elastomeric pad is stuck among each part.
The invention has the beneficial effects as follows:
1. consider from ergonomics angle, elastic construction can reduce the degree of fatigue of user
2. improve the useful life using button or trigger
3. install simple, replace easily
4. produce easily, with low cost
5. trigger configuration inside does not have unnecessary trigger travel, uses feel better.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is elastomeric pad Facad structure schematic diagram.
Fig. 3 is pad support Facad structure schematic diagram.
Wherein, 1. trigger, 2. elastomeric pad, 3. pad support, 4. push-button switch, 5.T nibs, 6. cylinder.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention will be further described.
In Fig. 1, push-button switch 4 is installed on circuit boards, circuit board is arranged in a groove of gun-type scanner plastic housing (identical with push-button switch in prior art 4 mounting means, repeat no more its concrete mounting structure), elastomeric pad support 3 is arranged on (identical with prior art Elastic pad support 3 mounting means, to repeat no more its concrete mounting structure) in another groove of plastic housing.Elastomeric pad 2 is just by three parts: pad support 3, trigger 1 and push-button switch 4 are stuck in centre and can not come off, and play the effect of elastic buffer simultaneously.Elastomeric pad 2 is arranged in the T-shaped hole 5 of pad support 3, can prevent its displacement.When another one flexure strip 2 changed by needs, only pad support 3 up need be extracted out, change another elastomeric pad 2, again load onto plastic housing, just can continue to use.
After trigger 1 is dynamic by finger hook, the cylinder 6 on trigger 1 is first oppressed elastomeric pad 2 and is produced deformation, and then elastomeric pad 2 promotes the button of push-button switch 4.When the displacement of button acquires a certain degree, push-button switch 4 starts action, triggered bar code identifier, for reading bar code information.
In this product, owing to employing elastic construction, make the user of Long-Time Service scanner, consider from ergonomics angle, feel is better, also can reduce fatigue.For different customers' demands, can when dispatching from the factory, configuration has the elastomeric pad of different DE easily.
