Abstract

The utility model discloses an expending and contracting device for a car lock without need of a key, at least comprising a slide bar and a bolt fastener rod, wherein, one end of the slide bar is provided with a spring bolt and a guide pin; the inner part of the bolt fastener rod is provided with a plurality of bolt holes with continuous arrangement and a circular guide groove where the guide pin slides. The bolt holes can make the spring bolt bunted in and stopped in a unidirectional mode. The two sections of insertion bodies can be mutually sheathed, and the slide bar can slides in the guide groove of the bolt fastener rod through the guide pin. So the spring bolt can disengage from the clamp of the bolt holes with continuous arrangement, the slide bar can be elongated or contracted relative to the bolt fastener rod, and the total length of the slide bar and the bolt fastener rod can be adjusted in a telescopic mode.

Description

Expending and contracting device for car lock without need of key

The utility model is the novel of a kind of automotive lock retractor device; Needn't can stretch with key when principal feature is to lock and draw or fold, be convenient to operation.

Known automotive lock kind is extremely many, and merits and faults and applicability thereof are respectively arranged; The general commonly used locking direction dish that is used for can be classified as two classes again, and one be horizontal, is about to lockset and is locked on the bearing circle (plane), extends a body of rod simultaneously, and this body of rod will hinder the operation of desire driver to bearing circle, and reach antitheft purpose; Another kind of handle lock is locking direction dish and pedal (pedal of clutch or Das Gaspedal), be commonly called as the crutch lock, usually have two parts, one is epimere shank and lockset part, another is a section shank under the extensible drawing, two bar phase fits and scalable its length, and lock it by lockset, to unblank earlier before using, extend its length then to also longer to the pedal spacing than bearing circle, an end hooks pedal earlier, and end is worn hook again on bearing circle in addition, fold two distance between tie rods then, extract key at last and lock and promptly reach chain purpose.

Crutch is locked in all Lock for automobile the most general, also the most cheap, thereby it uses the comfort feature of going up also more noticeable:

(1) no matter unblank, lock and all want key just scalable, inconvenience.

(2) unblank and to lean to one side or to bend over, except that inconvenience, more increase the danger of human body collision.

The consideration numerous based on the user and inconvenience is gone up in use, the creator is that the selected crutch lock of commonly using is as improveing object; Promptly, the utility model is locked at the crutch of commonly seeing and is improved design, the purpose of the utility model is to provide exempting from the flexible device of key of a kind of automotive lock, but mainly be to turn round in its spring joggle crossbar mat one pilot pin guide groove in bolt-buckle rod in the bolt-buckle rod body of stretching of mat, and the withdrawal that can freely stretch that can not open the lock with the key when locking causes effect easy to operate, rapid, that save time to reach; The inferior latch lever that extends that then can utilize the U type bar that is arranged at the bolt-buckle rod end or the core on the L type bar and the control of pulling thereof is unblanked and can operate separately, and is exempted the action of bending over or leaning to one side, the effectiveness of, easy operating comfortable to obtain.

The embodiment of the utility model will be described in conjunction with following accompanying drawing; Wherein:

Fig. 1 is the perspective exploded view of the utility model.

Fig. 2 is the cutaway view of the utility model.

Fig. 3 is the lateral plan of first embodiment of the utility model.

Fig. 4 is the lateral plan of second embodiment of the utility model.

Fig. 5 is that the utility model moves the scheme drawing in each stage.

As shown in Figures 1 and 2, the utility model is made of primary clusterings such as a slide bar 1, bolt-buckle rods 2, wherein:

Set firmly a spring joggle crossbar 11 in slide bar 1 one ends, a pilot pin 12 is then established in the tube wall outside near this end face; 11 of spring joggle crossbars are fixed on the slide bar 1 pipe end inwall by a block 111, establish tenon door bolt 112 and spring 113 again on block 111; Establishing a hole 114 on the slide bar 1 end tube wall fastens 11 tops with a bolt or latch for tenon and passes;

Bolt-buckle rod 2 is formed by interior pipe 21 and one outer tube 22 solid covers; Pipe 21 is provided with a plurality of continuously arranged door bolt eyes 211 wherein, and around the guide groove 212 of establishing a circulation round outside these a plurality of continuously arranged door bolt eye 211 peripheries, 211 sections ring plates 213 afterwards of the door bolt eye of the continuous setting of pipe 21 in figure one, after closing admittedly in outer tube 22, form the outer retaining wall of guide groove 212 rearmost ends.

The flexible operational scenario of the utility model embodiment as shown in Figure 2, slide bar (1) is with the slippage in the guide groove 212 of bolt-buckle rod 2 of its pilot pin 12, and the circulation that can enclose ring type is slided, in addition with its spring joggle crossbar 11 in the door bolt of arrangements continuously 211 contact to keep unidirectional location; Because tenon door bolt 112 be cambered surface or inclined-plane in one side (to the face that folds direction), thus slide bar 1 when this face direction slippage, tenon door bolt 112 can be supported to contract and by door bolt eye 211, otherwise, then can keep out in fastening with a bolt or latch in 211; Therefore the utility model pushes away in can slide bar 1 and utilizes spring joggle crossbar 11 instead to keep off, but and make slide bar 1 when spring joggle crossbar 11 can support door bolt eye 211 only in the one-way movement retraction bolt-buckle rod 2, and total length is dwindled; And after the pilot pin 12 of slide bar 1 angle of trackslipping in the short section of ring plate 213 at guide groove 212, spring joggle crossbar 11 promptly breaks away from the control of pulling of door bolt 211, and slide bar 1 can freely stretch with respect to bolt-buckle rod 2.

The embodiment of the utility model practical application as shown in Figure 3, Figure 4, slide bar 1 outer end sets firmly a L type bar 3, bolt-buckle rod 2 outer ends then can set firmly a U type bar 4 or another L type bar 5, this U type bar 4 or L type bar 5 are established a core 41 or 51 and in addition and are extended latch lever 42 or 52, wherein extending latch lever 52 front ends is the attached column body, and core 41 can be controlled the opening of extension latch lever 42 with locking U type bar 4, or open its opening; Core 5 then can be controlled it and extend latch lever 52 interlock tenon door bolt 112 again, and nature, tenon door bolt 112 are established a kerf groove 112a and led control so that the attached column body of extension latch lever 52 stretches into.

As shown in Figure 5, the pilot pin 12 of the utility model slide bar 1 can be in circulating guide groove 212 the circulation slide guide, and bolt-buckle rod 2 be provided with the arc sheet plate of door bolt eye 211 can the spot welding mode fixed, the punch press of (electrode bar system) certainly in addition, riveting dash fixed mode and be fixedly connected on the outer tube 22; Can find out by accompanying drawing, during two stages above pilot pin 12 is on the drawing guide groove of figure downside (be positioned at 212 sections), spring joggle crossbar 11 still as seen, but do not broken away from door bolt eye 211 in subordinate phase, and to rotation back (phase III on the drawing), spring joggle crossbar 11 has revolved the clip scope of taking off door bolt eye 211, spurs slide bar 1 this moment and can make it to be pulled to the longest attitude along sliding stretching, and rotates to the state of F/s again.So can freely stretch.

From the above: utilize the utility model, last when locking in vehicle steering and pedal, as long as holding slide bar (1) or the L type bar (3) on it, and the U type bar (4) on pipe (22) or its end outside the bolt-buckle rod (2), be condensed to earlier after the end rotates an angle again, promptly be stretchable to long status in case L type bar (3) can first hook due to pedal, fold again to fixed length, for locking behind U type bar (4) the open card Inbound dish, promptly finish and lock.Otherwise, when unblanking,, needn't bend over, lean to one side as long as the extension latch lever (42) that U type bar (4) is gone up is opened in operation on bearing circle.
