Description
Technical field
The present invention relates to slide rail, specifically a kind of three joint slide rail self-locking mechanisms.
Background technology
Slide rail is the sliding control member that all kinds of movable sliding doors usually adopt, in order to realize slide when packing up, can just not open voluntarily because of slight external force, in slide rail, usually all added self-locking mechanism, Structure of lock rod in existing self-locking mechanism is to be fixedly installed plated construction in locking bar base plate and locking bar on a body of rod, the locking bar groove being used in combination with Structure of lock rod is strip groove, from lock set during in open mode, the body of rod in Structure of lock rod slides into locking state in locking bar groove, the body of rod in Structure of lock rod is the structure that moves up and down, tight lock part is reliable, when being subject to External Force Acting, easily flick.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of three joint slide rail self-locking mechanisms are provided, adopt this self-locking mechanism can effectively realize the self-locking of slide rail, and this self-locking mechanism the problem of Off-Dog Fault can not occur at open position.
According to technical scheme of the present invention: a kind of three joint slide rail self-locking mechanisms, it is characterized in that: comprise the self-locking solution lock dog that is fixed on the self-locking base of outer rail rear end and is fixed on interior rail rear end, describedly from lock slide, slide and to be arranged on self-locking base, self-locking spring two ends are individually fixed on self-locking base bottom spring base and self-locking slider top spring base, on described self-locking base, offer the chute of arranging along its length, chute front end has horizontal kink, describedly between lock slide and self-locking base, be provided with rotation fixed block, the rotating shaft of rotation fixed block is stretched in the installing hole of lock slide, stretch out from the deep-slotted chip breaker from lock slide locking bar one end of rotation fixed block, the locking bar other end stretches in chute, on described self-locking solution lock dog, offer the groove matching with described locking bar.
As a further improvement on the present invention, described trench wall is arc transition shape, and groove outer end opening portion is from inside to outside the gaping expanding gradually, and groove is inner and dehisce to be formed with between portion projection.
As a further improvement on the present invention, described rotation fixed block comprises a holder, and described locking bar and rotating shaft are arranged at described holder two ends along its length, and wherein locking bar runs through described holder.
Technique effect of the present invention is: product structure of the present invention simply, rationally ingenious, by locking bar being arranged on rotation fixed block, and on lock slide, offering deep-slotted chip breaker simultaneously, can effectively guarantee that the phenomenon that breaks off relations and flick can not occur in open mode self-locking mechanism.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1 ~ 6, comprise self-locking base 1, from lock slide 2, rotation fixed block 3, holder 3-1, self-locking spring 4, outer rail 5, interior rail 6, deep-slotted chip breaker 7, locking bar 8, rotating shaft 9, self-locking solution lock dog 10, chute 11, laterally kink 12, groove 13, projection 14, inclined-plane 15 etc.
As shown in Fig. 1 ~ 5, the present invention is a kind of three joint slide rail self-locking mechanisms, comprise the self-locking solution lock dog 10 that is fixed on the self-locking base 1 of outer rail 5 rear ends and is fixed on interior rail 6 rear ends, describedly from lock slide 2, slide and be arranged on self-locking base 1, self-locking spring 4 two ends are individually fixed in self-locking base 1 bottom spring base and on lock slide 2 top spring bases, on described self-locking base 1, offer the chute 11 of arranging along its length, chute 11 front ends have horizontal kink 12, the described rotation fixed block 3 that is provided with between lock slide 2 and self-locking base 1, the rotating shaft 9 of rotation fixed block 3 is stretched in the installing hole of lock slide 2, stretch out from the deep-slotted chip breaker 7 from lock slide 2 locking bar 8 one end of rotation fixed block 3, locking bar 8 other ends stretch in chute 11, on described self-locking solution lock dog 10, offer the groove 13 matching with described locking bar 8.
Described groove 13 inwalls are arc transition shape, groove 13 outer end opening portions are the gaping expanding gradually from inside to outside, groove 13 is inner and dehisce to be formed with between portion projection 14, and the dehisce surface of portion of self-locking solution lock dog 10 front ends is inclined-plane 15, and the gradient direction on this inclined-plane 15 is that front end is low, rear end is high.
Described rotation fixed block 3 comprises a holder 3-1, and described locking bar 8 and rotating shaft 9 are arranged at described holder 3-1 two ends along its length, and wherein locking bar 8 runs through described holder 3-1.
The course of work of the present invention is as follows: when original state, interior rail 6 draws in and is fixed on outer rail 5, locking bar 8 on rotation fixed block 3 is placed in the groove 13 of self-locking solution lock dog 10, and fixed by projection 14, now self-locking spring 4 in the raw, due to self-locking mechanism of the present invention being installed on slide rail, can effectively guarantee that slide rail is when rounding state, interior rail 6 can not skid off from outer rail 5, when needs are opened slide rail, rail 6 in promoting forward, when thrust enough large, in the time of can overcoming the pulling force of self-locking spring 4, interior rail 6 is thrown off, realization being free to slide in middle rail, now self-locking solution lock dog 10 with from lock slide 2, throw off mutually, and now self-locking spring 4 is in extended state, from lock slide 2, slide into self-locking base 1 leading section, locking bar 8 is placed in the horizontal kink 12 of chute 11 front end, because locking bar 8 is fixed on a holder 3-1 with certain length, the state sliding in chute 11 at original state and locking bar 8, rotating shaft 9 and locking bar 8 and chute 11 are on same straight line, when sliding from lock slide 2 when locking bar 8 is in horizontal kink 12, now rotating shaft 9 is still on the extended line in chute 11, 8 straight lines that depart from chute 11 places of locking bar, locking bar 8 is carried out to force analysis known, the power that locking bar 8 is subject to can be decomposed into along chute 11 directions with perpendicular to chute 11 upward directions, these two power all can not allow locking bar 8 depart from horizontal kink, effectively guarantee the problem of Off-Dog Fault can not occur from lock set during at open position.
