Description

A kind of handle telescopic folding perambulator

Technical field

The utility model relates to a kind of folding baby carrier body frame structure for automotive, the telescopic folding baby carrier body frame structure for automotive of particularly a kind of handle.

Background technology

Folding baby carrier is because to have contractibility strong, easy to use, packing good characteristics of accumulating performance and being widely used.But all not flexibles of handle of existing folding baby carrier, thereby the frame for baby cart length after folding is longer, such folding baby carrier needs bigger packing and storage and transportation space relatively, and is so the expense of packing and accumulating is higher, also convenient not to the utmost when depositing.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of folding space littler handle telescopic folding perambulator at the deficiency of prior art existence.

The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: include vehicle frame, the vehicle frame lockout mechanism, wheel and handle, its difference is that described handle is scalable handle, constitute by Connection Block 9 and the handle 8 that is set in Connection Block, described vehicle frame lockout mechanism comprises back leg 13, handrail 4, Connection Block 9, connecting panel reaches the handle with the Connection Block phase configuration, back leg and handrail, connecting panel is hinged, Connection Block and handrail, the other end of connecting panel is hinged, on back leg, be installed on locking seat 12, with the elastic locking piece phase configuration that is installed in the handle lower end corresponding to the Connection Block lower end.

Press such scheme, on handle and Connection Block, be installed on handle and stretch out blocking device and handle recovery blocking device; Between Connection Block and connecting panel, be provided with the vehicle frame folding blocking device.

The beneficial effects of the utility model are: by adopting the Connection Block structure scalable handle is set, like this, at the vehicle frame folding pusher recyclable shortening, therefore vehicle frame volume and length after folding are further dwindled, this not only is convenient to depositing of user, and packing and storage and transportation space are dwindled, the packed and transported cost of folding baby carrier is further descended.

The specific embodiment

Further specify embodiment of the present utility model below in conjunction with accompanying drawing, it includes vehicle frame, vehicle frame is by the symmetrically arranged front leg 2 in the left and right sides, back leg 13, handrail 4, connecting rod 3, Connection Block 9 and connecting panel are hinged and form, wherein link to each other with connecting rod by handrail between front leg and the Connection Block and constitute a four-bar linkage (ABCD) in the vehicle frame, link to each other with connecting panel by handrail between back leg and the Connection Block and constitute another four-bar linkage (ECFG) in the vehicle frame, two four-bar linkages are combined into foldable chassis, and the lower end of vehicle frame is installed on wheel 1; In Connection Block, be set with handle 8, handle can be in Connection Block vertically before and after slippage, constitute scalable handle, be installed on an elasticity limiting stopper 19 in the bottom of handle, with spacing hole's 23 phase configuration of offering on the Connection Block, constitute handle and stretch out blocking device; Upper outside at handle is provided with elastic collet 6, and a cooresponding side is provided with positioning clamping pin 5 above Connection Block, constitutes handle thus and reclaims blocking device; In addition, also be installed on an extension bar 18 in handle, the upper end of extension bar links by joint 24 and the handle 7 that is arranged on handle top one side, and the lower end of extension bar connects lock dog 15 by stage clip 20, constitutes elastic locking piece, and elastic locking piece is positioned at the lower end of handle; The vehicle frame lockout mechanism comprises four connecting rods (ECFG) that are hinged and constituted by handrail and connecting panel between back leg 13 and the Connection Block 9, connecting panel is by interior, outside link plate 21,11 constitute, one end and back leg are hinged, on the back leg of this hinged place, be equipped with locking seat 12, in, the other end of outside link plate and Connection Block lower end are hinged, and make the elastic locking piece of handle lower end and the locking seat phase configuration on the back leg, when vehicle frame launches, four-bar linkage (ECFG) becomes three-link mechanism (ECG) after elastic locking piece and locking seat lock together, form the locking to vehicle frame.Spacing hole 23 on the corresponding Connection Block of inner face of interior connecting panel 21 is provided with flange 25, removes the locking of stretching out of handle when this flange is used for vehicle frame folding, and handle is reclaimed.Between Connection Block and inside and outside connecting panel, also be provided with the vehicle frame folding blocking device, the vehicle frame folding blocking device is made of the draw-in groove on elastic slip bayonet lock 10 and the inside and outside connecting panel, elastic slip bayonet lock 10 includes and is installed in the slide block 22 that links to each other with bayonet lock in the Connection Block, pull back spring 16 and slippage slot 17, Connection Block is exposed in the slide block lower end, projection 14 phase configuration that connect firmly with the handle lower end, after vehicle frame folding puts in place, bayonet lock springs into the draw-in groove on the inside and outside connecting panel automatically, connecting panel can not be relatively rotated, promptly finish locking folding stand.

The process that present embodiment launches locking is: push the elastic collet 6 on handle top aside, pulling handle 8 (moving to right) stretches out, and the projection 14 of handle lower end promotes elastic slip bayonet lock 10, makes bayonet lock deviate from the draw-in groove of inside and outside connecting panel, has removed the folding locking of vehicle frame; Meanwhile, the elasticity limiting stopper 19 of handle bottom slips into the spacing hole on the Connection Block, and handle is located in Connection Block; At this moment, can be with each structural member development of vehicle frame, after vehicle frame launched fully, the elastic locking piece 15 of handle lower end snapped in the locking seat 12 on the back leg, promptly finished the expansion and the locking of vehicle frame, and perambulator is in spendable implementation state.

The folding locking process of present embodiment is: the handle 7 drive extension bars on pulling handle 8 tops make and move locking seat 12 on the elastic locking piece 15, this moment, inside and outside connecting panel got final product relative rotation with Connection Block, other member also can overturn thereupon, when inside and outside connecting panel upwards overturns, elastic slip bayonet lock 10 relatively rotates along their edge curved surface, in case the folding back bayonet lock that puts in place springs into the draw-in groove on the inside and outside connecting panel, promptly finishes the folding and locking of vehicle frame; Meanwhile, flange on the interior connecting panel inner face is just in time corresponding to the spacing hole on the Connection Block, the elasticity limiting stopper 19 that plays locking action is headed in the Connection Block, make the axial latch-release of handle, handle can inwardly take in, concordant substantially until the handle lower end with rear wheel, the elastic collet 6 on handle top springs into the positioning clamping pin 5 of Connection Block top, make handle shrink locking, promptly finish the folding locking of whole vehicle frame, since the shortening of handle length H, the frame for baby cart volumetric spaces after therefore folding is littler.
