Description
Technical field
The invention belongs to the brightwork technical field, be specifically related to a kind of drawer self-locking mechanism of instrument bin
Background technology
The disclosed lockset for tool case of
Chinese invention patent publication number CN101672133A eliminated the deficiency of patent formerly such as CN1573002A (tool box rotating lock), CN2258219Y (lockset for tool box), CN2758032Y (tool box with buckle structure) and CN2705278Y (tool box fastener structures), objectively embodied all the technique effect with auto-lock function that comprise that first section of Instructions Page 3 concluded.But the shortcoming that has the structure relative complex.
Chinese design patent notice of authorization CN3341116S discloses structure drawer self-locking mechanism as shown in Figure 3; Comprise locking plate seat 1 and locking plate hook 2; Offer elongated slot on the locking plate hook 2, in position locking plate hook 2 is matched with on the locking plate seat 1 corresponding to elongated slot with bearing pin.With illustrated location status is example, in use the outside of locking plate seat 1 usefulness pair of screws and drawer backboard is fixed, when will be in drawer that the state of pulling out promptly is in opening towards the drawer chamber promptly when the direction such as the casing in tool box pushes; Contact with bolt on being preset in casing by the slide plane of locking plate hook 2, make locking plate hook 2, treat just to fall automatically after locking plate hook 2 is crossed the hole on the bolt on the casing to top offset; Thereby embodiment auto-lock function; Though this self-locking device has the foolproof strong point of structure, because locking plate hook 2 is to be arranged on the locking plate seat 1 through bearing pin; And because bearing pin is corresponding to the elongated slot of locking plate hook 2; Thereby after the angle that the tool box tilts and even the exhibition of pulling is certain, locking plate hook 2 just moves towards the rightabout with previous locking on bearing pin under the deadweight effect after 90 ° of the exhibitions of for example pulling, and makes the bolt on the casing lose stopping locking plate hook 2; Drawer just can be pulled out, thereby and has an insecurity.In addition, also have another kind of situation, that is exactly, and when the tool box vibration is rocked, can cause locking plate hook 2 to be in released state too, also can be referring to A, B and the C portion enlarged drawing of CN3341116S to this.
In view of above-mentioned prior art, be necessary rationally to improve, for this reason, the applicant has done useful design, and the technical scheme that will introduce below produces under this background
Summary of the invention

The specific embodiment
can be expressly understood technical spirit of the present invention and beneficial effect more for the auditor that the makes Patent Office especially public; The applicant general elaborates with the mode of embodiment below; But the description to embodiment all is not the restriction to the present invention program, any according to the present invention design done only for pro forma but not substantial equivalent transformation all should be regarded as technical scheme category of the present invention.
Embodiment:
Fig. 1 is asked for an interview in
; Show the casing 3 of instrument bin; On this casing 3 and towards a side of the following drawer that also will mention 7, be fixed with a guide rail pipe 4 with hold-down screw 42, the short transverse of guide rail pipe 4 has guide rail tube chamber 43, and offers the vallecular cavity 41 that communicates with guide rail tube chamber 43 at this guide rail pipe 4 towards a side of drawer 7; Shown in figure, the shape of cross section of whole guide rail pipe 4 is a font on body.
The bolt 5 that
shape of cross section is a font is installed with slidably in the guide rail tube chamber 43 of guide rail pipe 4, and on this bolt 5 and equally the side towards drawer 7 offers locking plate dog hole 51.According to common practise, on a casing 3, can or claim to set from bottom to up a plurality of four drawers 7 for example illustrating from top to bottom by Fig. 2, therefore on bolt 5, have locking plate dog hole 51 corresponding to each drawer 7.Constitute a coulisse 52 at the top of locking plate hook 5, on this coulisse 52, offer a chute 521.Pivot is arranged on the casing 3 key actuated lock shaft 6 through axle bed 63; And this key actuated lock shaft 6 is connected with bolt 5 towards an end of bolt 5; Specifically: the shape of this end of key actuated lock shaft 6 is bent into zigzag; And this end end of key actuated lock shaft 6 is inserted in the aforesaid chute 521, be provided with a back-up ring 61 at the axle head of the key actuated lock shaft 6 that leans out chute 521, and this back-up ring 61 is stopped by the backing pin 62 that is located on the key actuated lock shaft 6.When ordering about 6 rotations of key actuated lock shaft with key, just drive bolt 5 motions.Drawer 7 is arranged in the drawer chamber 31 by the casing 3 of Fig. 2 signal.
Fig. 1 please be continued to see in
; Provided the preferred construction of drawer self-locking mechanism; Comprise a locking plate seat 1, locking plate hook 2 and spring 8, locking plate seat 1 is fixing with the drawer backboard 71 of aforesaid drawer 7 by securing member 12, and securing member 7 can be a screw; Also can be rivet such as self-plugging rivet, can also be other similar parts.Preferably, locking plate seat 1 is fixed on the placed in the middle position of drawer backboard 71 towards a side of bolt 5, that is to say that locking plate seat 1 occupy the middle part of the length direction of drawer backboard 71.On locking plate seat 1, constitute a locking plate hook seat 11.This locking plate hook seat 11 has a chamber 111, and the top in seat chamber 111 offers a locking plate hook slot to make way 1111, and on the seat chamber diapire 1112 in present chamber 111 and be positioned at the middle position and constitute a support lug 1113.Locking plate hook 2 all is contained in the chamber 111 with spring 8, and wherein, the upper end of locking plate hook 2 constitutes locking plate gib head 21; This locking plate gib head 21 is corresponding to aforesaid locking plate hook slot to make way 1111; And on this locking plate gib head 21, be formed with a spigot surface 211, this spigot surface 211 is the circular arc spigot surface, and towards bolt 5; More particularly, constitute a spring base 22 in the lower end of locking plate hook 2 towards locking plate dog hole 51.One end of spring 8 is that illustrated lower end is bearing on the aforesaid support lug 1113, is bearing on the spring base 22 and the other end is illustrated upper end.
are example by location status shown in Figure 1, and when artificially drawer 7 being applied the thrust towards the direction displacement of casing 3, then locking plate gib head 21 is under the guiding of its spigot surface 211 and overcoming under the active force of spring 8 and get into locking plate dog hole 51; In case locking plate gib head 21 gets into locking plate dog hole 51; Then under the release force effect of spring 8, locking plate hook 2 is upwards pushed away, make the locking plate gib head 21 of locking plate hook 2 suffer the stopping of blocking surface 53 of bolt 5, thereby drawer 7 is automatically locked; Drawer 7 can not be able to outwards pull out because of situations such as the inclination of casing 3, inversion, vibrations; Only if launch key to aforesaid key actuated lock shaft 6 effects, bolt 5 upwards carried moved, so that remove stopping of 53 pairs of locking plate gib heads 21 of blocking surface; That is to say; Make locking plate gib head 21 integral body corresponding to locking plate dog hole 51, just be able in this state drawer 7 is outwards pulled out, therefore have the reliable and secure effect that automatically locks.
Application examples:
Fig. 2 is asked for an interview in
, has provided the casing 3 of being furnished with four drawers 7 that are not limited to illustrate quantity, and shown in figure, four drawer 7 from top to down can be contained on the casing 3 in the drawer chamber 31 that sets out with plugging.In the time will launching, also promptly, when drawer 7 is outwards pulled out; Then with key key lock 9 is operated, owing to aforesaid key actuated lock shaft 6 is connected with key lock 9, therefore by the user; Drive key lock shaft 6 by the lock core of key lock 9 and do counterclockwise to rotate because the coulisse 52 of bolt 5 is connected with key actuated lock shaft 6, so by key actuated lock shaft 6 drive bolts 5 to top offset; Releasing stops the locking plate gib head 21 of the locking plate hook 2 of drawer self-locking mechanism, thereby can drawer 7 outwards be pulled out
