Abstract

The utility model relates to a spring key remote controller, comprising a hollow shell, a slide base gliding in the shell, a key fixed on the slide base, a control piece fixed on the slide and partly extending out of the shell, a gear articulated with the slide base, a rack arranged on inner wall of the shell body and engaged with the gear, a spring generating elasticity to drive the slide base moving forward in normal status and two operational rods pivoted in the shell; wherein, middle section of the each operational rod is articulated in the shell, with one end of the operational rod is placed at the outer surface of the shell and the other end is fastened to lateral of the slide base. The key is positioned in the shell; when the key needs to be protruded, one can press one end of the two operational rods so as to make the other end deflect and unchain from slide base, then the slide base moves forwards under effect of the spring and avoids the instant ejection due to proper resistance provided by rolling gear.

Description

The elastic press type keyfob

Technical field

The utility model system belongs to the technical field of key, but refers to a kind of key retraction or outstanding keyfob especially.

Background technology

When key was positioned in the sack of pocket or handbag, not only because length is long is inconvenient to collect, and end and side often were made as cone-shaped, zigzag and very easily scratch pocket.Again, the gate of Modern Residence or garage use the probability of iron rolling door high, when therefore going out, not only need to carry key, also need to carry remote controller, often are key one big strings and quite be inconvenient to carry.In order to improve the not portative defective of key, so there is the dealer to design remote controller in a kind of housing that key can be concealed in remote controller, as No. 328312 " the remote controller key is stretched and received location structure " novel patent case (hereinafter to be referred as the reference case) of Taiwan patent announcement, the slide and one that is provided with a controlled displacement in the housing of remote controller stays on the start spring of this slide, on slide, fix a key that can be stretched on outside the housing, when operating this slide toward this end movement of start spring, compressible this start spring and key is accommodated in the housing, and be positioned in the housing by a control member blocking of being located on the slide.When desire is used key, remove the blocking state of this control member, promptly slide and key are released forward by the elastic force of start spring.

Yet when one removed the blocking state of control member, this start spring was about to key moment and releases forward, and the speed of its ejection is exceedingly fast, and easily makes housing and is damaged because impact.When control member is pushed in operation again, when finger still forces in control member, the start spring can't be released slide smoothly, but whether uncertain again its abaculus of operator has broken away to the voussoir below, therefore, must suppress control member during practical operation earlier and make its abaculus break away from the voussoir scope, again control member slightly be pushed away forward, the start spring is released slide together with key.

The utility model content

The utility model is to impact housing in order to remove above-mentioned reference case key to eject fast, be inconvenient to operate and monolateral processing ease is crooked and defective such as damage and carry out improved.

In order to improve the problems referred to above, the major technique means that the utility model is taked are for providing a kind of elastic press type keyfob, lie in the slide of establishing a slip in the hollow housing of remote controller, on this slide, fix a key that can be stretched on the housing front end, and the control member that can local be piercing on the perisporium vertical with front end, in housing, be provided with one in addition and be placed through the guide bar of slide, and a normality is bestowed the start spring of slide towards the elastic force of front end slippage with fore-and-aft direction, wherein

The opposite side that slide the is positioned at control member axial gear vertical that be pivoted with key, in housing, be provided with in addition one with the tooth bar of gears engaged, and the bearing of trend of this tooth bar is parallel with the bearing of trend of key.

In addition, the further technological means of the present utility model dual side-edge that lies in housing is respectively equipped with a handle hole that runs through perisporium; Described slide two side adjacent back end places are arranged with a draw-in groove respectively; If two action bars, it is to be hubbed at enclosure interior with the stage casing, and a wherein end of two action bars is made as the operating portion that is positioned at handle hole, and the other end is made as projection in opposite directions and distinguishes plug-in card in the buckle piece of draw-in groove; If two springs are that normality is bestowed the power that operating portion is partial to handle hole respectively.

Implement after the above-mentioned technological means, the obtainable concrete benefit of the utility model is:

1. because slide of the present utility model is provided with gear, and enclosure interior is provided with the tooth bar with gears engaged, when the slide slippage, gear produces to roll can provide suitable resistance, avoid slide to be subjected to the elastic force of start spring and moment dashes forward, improve that housing with reference to case is vulnerable to impact and the defective damaged.

2. work as the utility model and be provided with action bars, in the time of in the key income housing, the draw-in groove of its slide two sides is subjected to the buckle piece plug-in card location of action bars respectively, when the desire operation is given prominence to key, push the operating portion of two action bars simultaneously with two fingers, even the other end is LRO Lateral Runout and remove buckle state with slide outwardly, slide promptly be subjected to the start spring the elastic force effect and towards the place ahead slippage, because slide two sides are subjected to blocking simultaneously, its mean forced, displacement forward reposefully when moment is removed the blocking state, and since during operation as long as the pressing operation bar, can reach the purpose of handled easily.
