The specific embodiment
Below in conjunction with accompanying drawing, the utility model is made to concrete further instruction.
As Figure 1-5: the adjustable perambulator of a kind of spinal support angle, it comprises vehicle frame 1, and be arranged on front-wheel 11 and the trailing wheel 12 on vehicle frame 1, the front end of vehicle frame is movably hinged with steering handle 3, the middle part of vehicle frame is installed with seat 4, it is characterized in that: described seat 4 is connected with backrest 5 by the turning joint with registration device;
Wherein: described turning joint comprises the circular steady ring 41 that is arranged on 4 both sides, seat, and is arranged on the turning sleeve 51 of backrest 5 belows, and turning sleeve 51 is arranged on outside steady ring 41 and can coaxially freely rotates around its work;
Wherein: described registration device comprises the lock ring 42 that is arranged on 41 of above-mentioned turning sleeve 51 and steady rings, and lock ring 42 inside faces are provided with some grades of positioning boss 43, and this positioning boss 43 can be snapped in the positioning groove 44 that is arranged on steady ring 41 surfaces;
Described turning sleeve 51 inside faces are provided with some positive stop lug boss 8 and match with the limited impression 81 that is arranged on lock ring 42 outside faces; Being provided with operating handle 2 outside described turning sleeve 51 is fixedly connected with lock ring 42 by screw, the push-and-pull operating handle, can make lock ring under the effect of limited impression, along this positive stop lug boss, be in axial sliding, positive stop lug boss plays the effect that prevents that lock ring from being turned by band, 51 of described lock ring 42 and turning sleeves are provided with pre-compressed spring 9, and spring produces thrust makes lock ring move to the steady ring direction all the time.
Described steady ring 41 can integrated injection molding with seat 4.
The independent injection mo(u)lding of described steady ring 41, be fixedly mounted on the pedestal 411 of 4 both sides, seat, and steady ring 41 inwalls are provided with inwardly protruded buckle 412, and buckle inserts the interior anti-rotation positioning function that realizes of groove 413 on pedestal 411 surfaces; One side of described steady ring 41 corresponding pedestals is provided with anti-tripping 414 to direction projection in hole, and this is anti-tripping inserts in the scrobicular ring 415 of pedestal 411 roots, plays and prevents the axially movable function of steady ring.In the utility model, because steady ring need to bear the thrust that human body imposes on backrest, so require steady ring to there is certain toughness and impact resistance.Body material does not need too high requirement, and large more options PP material is made.Institute thinks the assurance properties of product, and the utility model is selected split production, with the better nylon material of overall performance, makes steady ring and lock ring, refills to be fitted on pedestal and uses, and in assurance function, reduces production costs.
Be arranged with a pair of elastic spacing post 52 in described turning sleeve 51, accordingly, be provided with the spacing hole 45 that the elastic spacing post is installed on lock ring 42.After installing, limited post limitation lock stop ring is to the path of motion of steady ring direction.
Consider the convenience of operation and reduce production costs, described lock ring 42, steady ring 41 and operating handle 2 only are arranged on the chair back wherein in the turning sleeve of a side, and opposite side only needs turning sleeve 51 and pedestal 411 to make coaxial cooperation to get final product.
As shown in Fig. 5-8, each handrail 6, two handrail tops that are extended with forward an arc, described backrest 5 both sides connect by hinged seat 61; The top of described vehicle frame is equipped with the armrest seat 63 with snap lock clamping 62, and described hinged seat is provided with mounting hole 64 and is fastened on the snap lock clamping and is connected with armrest seat.
Described snap lock clamping 62 has two, is symmetricly set on the upper and lower surface of armrest seat 63, between two locking buttons, is equipped with top spring 631.
As shown in Fig. 9,10: described backrest 5 both sides are provided with the registration mast 7 to outer process, fixing with the latching device 91 that is arranged on handrail 6 inboards.
Described latching device comprises the platform 911 that is arranged on the handrail inboard, jump and offer locking plate groove 912 downwards in the platform upper surface, locking plate groove 912 connects with the inboard of platform, lock banking stop 914 to upper support is installed in described locking plate groove 912 by spring 913, and lock banking stop is provided with some levels can be snapped into lockhole 915 on registration mast 7.
Described lock banking stop 914 two ends are provided with the back-off 916 of tape guide slide unit, and under the support of spring 913, the back-off on lock banking stop 914 can slide up and down in the anticreep groove in locking plate groove 912.
Principle of work: when the needs adjusting angle of backrest, press the lock banking stop of handrail both sides, make the macropore place of lockhole on lock banking stop align with registration mast, outwards pull handrail, rotate along hinged seat on the handrail top, and latching device is separated with registration mast.Then the operating handle of chair back both sides is pulled out, lock ring is under the effect of limited impression, along positive stop lug boss, outwards move, pre-compressed spring is compressed, when handle motion to a certain extent the time, force lock ring and steady ring to break away from, the chair back can rotate round the center of circle of steady ring, thereby realizes the relative angle purpose between adjusting back and seat.After angular adjustment is good, the unclamp operation handle, under the thrust of pre-compressed spring, lock ring is docked with steady ring again, snare is outside steady ring, and the positioning boss 43 on steady ring buckles in the positioning groove 44 on steady ring 41 surfaces again, realizes the purpose of locking backrest angle.Owing between lock ring and turning sleeve, being provided with pre-compressed spring, the thrust of its generation has the function that prevents the lock ring dislocation, guarantees the locking reliability of backrest.After seat angle has been regulated, again press lock banking stop, make registration mast insert in the lockhole of lock banking stop, unclamp lock banking stop, under the effect of spring force, lock banking stop is by the jack-up that makes progress, make on the small bore end cutting ferrule registration mast of lockhole, realize the function that handrail and backrest reconnect.
When children arrive certain age, after having had awareness of safety, the user can separate the latching device of armrest rear end 91 with backrest, press the locking button be arranged on armrest seat, make the mounting hole 64 on itself and hinged seat break away from, can be by the handrail overall separation, just with children's upper and lower perambulator voluntarily.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, as steady ring and the form of docking of lock ring and the connection mode of slippage location, handrail and hinged seat between associated materials application, fastener positioning structure, handrail and backrest, working forms of operating handle etc.Here exhaustive without also giving all embodiments.And the apparent variation of being extended out thus or change are still among the protection domain of the claims in the invention.
