Abstract

The utility model relates to a structure with adjustable height for a combined desk cabinet, which is mainly composed of a clamping groove, a blocking body and a hollow part. When the clamping groove is punched by a movable plate, the blocking body and the hollow part are transversely crossed on both sides of the clamping groove and are connected into an integral body. Good structural strength of the blocking body and the hollow part can be realized, and the state that a shaft column of a pulling rod can not slide into the hollow part when the shaft column of the pulling rod crashes the blocking body and deforms can be effectively avoided.

Description

The structure of the height adjusted of combined type table cabinet

The utility model relates to a kind of structure of the height adjusted of combined type table cabinet, mainly be: this portable plate is when the punching press slot, block body and hollow-out parts are across the slot both sides and link into an integrated entity, allow block body and hollow-out parts have the structure of preferable intensity, the jack-post that effectively prevents to dial arm deforms when the collision block body and can't slip into the situation of hollow-out parts.

The height the adjusted structure (ZL98200048.0) of the present a kind of combined type table cabinet that uses, as depicted in figs. 1 and 2, it mainly is: these drawout cubicle 10 bottoms are provided with pulley 11, can arrange in pairs or groups with the combined type desk by mobile easily drawout cubicle 10, block position, and run through groove seat 12 in the position, both sides of drawout cubicle 10 central authorities, as a fixed head 30 and a backplate 40 of burying a band crimp underground, these fixed head 30 both sides are drilled with plurality of holes 31, by screw P fixed head 30 and backplate 40 locks are tied on groove seat 12, and on the crimp above the fixed head 30, cut open and establish opening 32, it is for a sheathed backplate 40 and plug a portable plate 50, in addition respectively on fixed head 30, the upper/lower positions place wears open-work 33,34, be to tie a gear 35 and one group of arm 60 for sheathed pivot, and the top of this group arm 60, two circular holes 61 are run through in position, the end, 62, it ties two jack-posts 63 for pivot, 64, in the middle of dialling arm 60, be drilled with an open-work 65 again, as plugging a torque spring S, the end pin S1 of torque spring S wherein, it is inserted in the open-work 65 of dialling arm 60, other end pin S2, then collude in the line of rabbet joint 36 of being located at fixed head 30 root edges, the elastic force effect that makes group arm 60 be subjected to torque spring S forms a left side, the state of right avertence pendulum, make relative type track 37 again in fixed head 30 two bottom sides positions, by the above-mentioned portable plate 50 of type track 37 restrictions; And this portable plate 50 mainly be below hollow out make the cartridge groove 51 of continuous multi-stage, and utilize screw P to lock in portable plate 50 sides and tie a tooth bar 52, make portable plate 50 can utilize on the gear 35 of tooth bar 52 and fixed head 30 is meshing with each other, lower slider, the jack-post 63 of dialling arm 60 tops simultaneously contains in the continuous multi-stage slot 51 of being located at portable plate 50, allow jack-post 63 beat and block bullet and be positioned in the continuous multi-stage slot 51 left of dialling arm 60, and the slot 51 adjacent other block bodies 53 of setting up at bottommost, allow the jack-post 63 of swing arm 60 touch after the block body 53, promptly beat is positioned in the slot 51 of bottommost left, dial arm 60 at last and can return to the original state of beat to the right simultaneously by block body 53 hollow-out parts 54, make swing arm 60 go back up to the card bullet positioning relation with top slot 51, fix a support body 70 in portable plate 50 tops lock knot in addition, again support body 70 lock knots are fixed in the position, both sides of desktop 80 bottoms.

But the novel patent case of the height adjusted structure of combinations thereof formula table cabinet, actual fabrication with use, still exist at least following several both deposit shortcoming and problem:

1. when making, slot, block body, the hollow-out parts of portable plate below hollow out are the slots that strikes out multistage earlier, again the partly stubborn folding of the reservation of slot below is made into block body and hollow-out parts, must just can finish, make to seem not only time-consuming but also take a lot of work in the making through the twice procedure.

2. when using, because block body only links to each other with slot then on one side with hollow-out parts, when the jack-post of dialling arm collides block body, be very easy to cause block body and hollow-out parts to deform or the situation that severs, when yet in a single day block body and hollow-out parts deform, smooth and easy in the time of promptly can having influence on the jack-post of dialling arm and slip into, even can be stuck and can't move.

The purpose of this utility model is to propose a kind of structure of the height adjusted of the combined type table cabinet of being made up of slot, block body and hollow-out parts, because portable plate is when the punching press slot, block body and hollow-out parts are to be across the slot both sides to link into an integrated entity, make block body and hollow-out parts have preferable structural strength, thereby solved the problem that prior art exists.

The technical scheme that the utility model adopted is:

It mainly is: the both sides installing fixed head of this cabinet, and respectively on fixed head, upper/lower positions place pivot knot is provided with a gear and one group of arm, be subjected to the elastic force effect of torque spring in the middle of right this group arm and beat to the left or to the right, and make track in the fixed head both sides, be engaged in the sheathed backplate of opening of fixed head top in addition, plug a portable plate with the rank system, and this portable plate below is the slot that hollow out is provided with continuous multi-stage, again at portable plate side lock knot one tooth bar, again with the transmission that is meshing with each other of the gear of fixed head, in portable plate top lock knot one support body, fix a desktop again as the lock knot; When adjusting the high and low position of desktop, the tooth bar of portable plate can slide along the gear of fixed head, utilizes the slot formation card bullet fixing state of arm beat positioning action along continuous multi-stage of dialling simultaneously; It is characterized in that: the block body of this portable plate and hollow-out parts are across being connected in the slot both sides, can increasing the structural strength of block body and hollow-out parts, preventing that backstop and hollow-out parts deform.

Advantage of the present utility model is that the block body of this portable plate and hollow-out parts are across the both sides that are connected in slot, and it can strengthen the structural strength of block body and hollow-out parts.

Fig. 1 and Fig. 2 are respectively the three-dimensional exploded view of prior art and adjust the perspective exploded view of structure.

Fig. 3 is a perspective exploded view of the present utility model.

View when Fig. 4 reduces for the utility model.

The view of Fig. 5 for the time with novel rising.

Further specify preferred embodiment of the present utility model in conjunction with above-mentioned each accompanying drawing now.As shown in Figure 3: it is a perspective exploded view of the present utility model.It mainly comprises: portable plate 50 below punching press hollow outs make the slot 51 of continuous multi-stage, and make block body 53 and hollow-out parts 54 across slot 51 both sides in the bottommost punching press of slot 51, so as to increasing the strength of connection between block body 53, hollow-out parts 54 and the slot 51, the worry that effectively anti-backstop 53 and hollow-out parts 54 deform.

The structure of the height adjusted of a kind of combined type table of the utility model cabinet of forming by above-mentioned each element, on practical operation was used, as shown in Figure 4, it was the view of the utility model when reducing.After the jack-post 63 of dialling arm 60 is colliding block body 53, can be positioned in the slot 51 of lowest part by beat.View when shown in Figure 5 is the utility model rising.When the jack-post 63 of dialling arm 60 by after the hollow-out parts 54 of block body 53, promptly can return to original erectility, make the jack-post 63 of dialling arm 60 can go back up to slot 51 positions at top.
