Abstract

The utility model discloses a drawer with a positioning mechanism capable of unlocking compulsively parallel to a pull-out direction on a medical trolley. The structure of the drawer is that a commodity guide rail or a self-made guide rail is arranged on an inner side board of a trolley body, and the guide rail is connected with the drawer. A pull hand is fixed on a drawer panel and connected with a lifting hand. A horizontal rod is connected with the reverse side of the lifting hand, and locking hooks are fixed at two ends of the horizontal rod. The lifting hand on the horizontal rod is connected with a revolving shaft through the drawer panel, and a returning spring is arranged between the revolving shaft and the drawer panel. The locking hooks and locking holes in the front end of side boards are arranged correspondingly. The drawer has the advantages that the locking hooks parallel to the drawer pull-out direction are utilized for positioning, meanwhile, the locking hooks are utilized for positioning in a rotating mode at two ends of the drawer, when the drawer can not be pulled out, service can be provided for a patient in time by compulsively unlocking, and use specifications of a lock by a medical and health department can be fully ensured. Meanwhile, the drawer is simple in design structure, few in accessories and reliable in use, and can be easily applied to industrial production.

Description

But drawer has the compulsive unlocking detent mechanism that is parallel to pull-out direction

Technical field

A kind ofly have the detent mechanism that is parallel to the pull-out direction compulsive unlocking for the drawer on the trolley for hospital use but the utility model relates to, belong to trolley for hospital use manufacturing technology field.

Background technology

Trolley for hospital use is the instrument that transports that health service unit often uses, and places putting articles such as each quasi drugs, doctor's auxiliary material, operating theater instruments, therapeutic device, case history, card by the drawer that uses go-cart to each field of employment of health service unit.Therefore must can not cause drawer to skid off because of mobile in the moving movement process.Removing on the market at present is to utilize the block rubber on the track to locate by frictional force, but block rubber wears out easily and makes locate failure.

Have detent mechanism such as patent of invention 2010105008764 perpendicular to the handle direction by drawer, its defective is: 1) structure is loaded down with trivial details, and suitability for industrialized production is difficult, and in the life-time service, its labyrinth lost efficacy easily; 2) if locate failure or location locking can not be pulled out drawer, then need destroy the dismounting car body and could take out article in the drawer.This is for the health service unit curing patient, particularly during first-aid patients, medicine or treatment equipment can occur taking out and the danger that postpones to give emergency treatment to a patient.

Summary of the invention

But the utility model proposes a kind of compulsive unlocking detent mechanism that is parallel to pull-out direction that has for the drawer on the trolley for hospital use, can under any circumstance can both effectively limit drawer locatees because inertia skids off in body movement, guaranteeing when locate failure can release, forces to pull the drawer out to take out medicine and therapeutic device in the drawer.

Technical solution of the present utility model: it is characterized in that at the interior plate of car body commodity track or self-control track being installed, this track is connected with drawer, fixing handle on the drawer panel, handle is connected with handle, the reverse side of handle connects cross bar, and the two ends of cross bar are latch hook fixedly, and the handle on the cross bar links to each other with rotating shaft by drawer panel, between rotating shaft and drawer panel, back-moving spring is installed, the corresponding setting of lockhole of latch hook and side plate front end.

Advantage of the present utility model: adopt the latch hook location parallel with the drawer pull-out direction, adopt the latch hook rotational positioning simultaneously again at the drawer two ends, when the detent mechanism lock lost efficacy, in the time of can't pulling the drawer out, because being the latch hook by the two ends on the drawer panel, drawer locks, the available metal thin slice inserts between drawer panel and the side plate, in the upper end of latch hook in both sides respectively to pressing down latch hook, just latch hook can be broken away from lockhole, drawer just can be pulled out, thereby at the location locking, in the time that drawer can not being pulled out, in time be patient's service by compulsive unlocking.Fill part and guarantee that it is simple to have project organization simultaneously at the operating specification of health service unit for lock, number of fitting parts is few, use reliable, be easy to suitability for industrialized production and use.

Description of drawings

But being drawer, accompanying drawing 1 has the structural representation of the compulsive unlocking detent mechanism trolley for hospital use that is parallel to pull-out direction.

Accompanying drawing 2 is sketch maps of latch hook location structure.

Accompanying drawing 3 is sketch maps of handle and latch hook rotary state.

Among the figure 1 is car body, the 2nd, drawer, the 3rd, castor, the 4th, panel, the 5th, handle, the 6th, handle, the 7th, cross bar, the 8th, rotating shaft, the 9th, back-moving spring, the 10th, latch hook, the 11st, lockhole, the 12nd, side plate.

The specific embodiment

Contrast accompanying drawing, its structure are that the interior plate at car body 1 is equipped with commodity track or self-control track and is connected with drawer 2, as shown in Figure 1.Drawer 2 comprises panel 4, handle 5, wherein shake hands 5 to be contained on the panel 4, described handle 5 connects handle 6, the back side of handle 6 is connected with cross bar 7, the two ends of this cross bar 7 are latch hook 10 fixedly, handle 6 links to each other with rotating shaft 8 by drawer panel 4, between rotating shaft 8 and drawer panel 4 back-moving spring 9 is installed, as shown in Figure 2.It is L shaped that described latch hook 10 is barb, this latch hook 10 matches with the lockhole 11 of side plate 12 front ends, when drawer is closed to car body, latch hook 10 bump lockholes, latch hook moves downward, latch hook enters lockhole, back-moving spring 9 resets, and the barb of latch hook 10 fastens lockhole 11, and drawer 2 can not be pulled out, play the effect of location self-locking, also rotate by rotating shaft 9 when handle 6 upwards drives cross bar 7, the latch hook 10 at cross bar 7 two ends that are rotated also rotates, and makes latch hook 10 break away from lockholes 11, drawer 2 just can be pulled out, as shown in Figure 3.When the detent mechanism lock lost efficacy, can't pull the drawer out 2 o'clock, because being the latch hooks 10 by the two ends on the drawer panel 4, drawer 2 locks, insert between drawer panel 4 and the side plate 12 with foil, this foil respectively to pressing down latch hook 10, breaks away from lockholes 11 with latch hook 10 in the both sides of the upper end of latch hook 10, drawer 2 just can be pulled out, thereby at the location locking, in the time that drawer can not being pulled out, in time be patient's service by compulsive unlocking.
