Abstract
The utility model relates to an automatic locking device for a pram, which comprises a positioning sleeve, a spring, a movable sleeve, etc., wherein the positioning sleeve is fixed on a handspike, the movable sleeve is sheathed on the positioning sleeve, and a guiding device is arranged at the matching place of the positioning sleeve and the movable sleeve. A compression spring is arranged between the positioning sleeve and the movable sleeve. A positioning screw is arranged on the handspike at the lower part of the movable sleeve, and the other tube sleeve which is parallel with the shaft line of the positioning sleeve is arranged on the movable sleeve corresponding to a locking supporting rod and the opening of a tube has an obliquity. When the pram is used, the handspike drives the tube sleeve of the movable sleeve to be sheathed on the locking supporting rod through the guide of the inclined opening. The utility model has the advantages of automatic locking, safe and convenient use.
Description
The utility model relates to a kind of hand propelled perambulator, and is especially relevant with its securing arrangement.
Commonly using the locking of hand propelled perambulator is finished by a movable hook and a fixed cover, make whole body framwork robust structure triangular in shape after the locking, but be nested with fixed cover because of forgetting when using, and movable hook easily comes off, when the speed of a motor vehicle is fast slightly, often amount to trend, damage baby's incident because of the inequality of exerting oneself produces car.
The purpose of this utility model is to provide a kind of device that automatically locks of perambulator, and is safe in utilization because of its locking is operatorless device, conveniently.
For achieving the above object, the device that automatically locks of the present utility model is made up of members such as a locating bush, a spring and movable sleeves; Locating bush is a hollow circular cylinder that is nested with on the hand push body of rod, its appropriate position perpendicular to axial direction wears a pin-and-hole, be set on the pin-and-hole and the hand push body of rod on the cooresponding hole by locating dowel pin, locating bush is installed with on handspike, the locating bush lateral process is established a raised line; Movable sleeve is nested with on locating bush, its inboard is arranged with a strip groove, raised line proper and on the locating bush cooperates, place a compression spring between locating bush and the movable sleeve, establish a location screw on the handspike of movable sleeve below, on the movable sleeve corresponding locking pole establish one with another pipe box of positioning sleeving shaft line parallel, and the mouth of pipe establishes a gradient, so that locking pole is by locking in the outer importing pipe box.During use, perambulator is propped, the movable sleeve that handspike drives locking device automatically is nested with on locking pole, forms leg-of-mutton rigid support structure.
Locating bush of the present utility model also can be the polygonal cylinder that is installed with on handspike; Movable sleeve for cooperate with it, in be the structure in polygonal column hole, by polygonal cylindricality fit structure, make the movable sleeve motion orientation, the corresponding locking of movable sleeve pole be provided with equally one with the pipe box of positioning sleeving shaft line parallel, and the mouth of pipe is established a gradient, imports in the pipe box in order to locking pole to lock.
Because the utility model the being provided with device that automatically locks, can avoid forgeing locking and cause the accident, safe in utilization, convenient.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model main body exploded drawings;
Fig. 2 is the utility model main body assembly drawing;
Fig. 3 is the axial cutaway view of the utility model movable sleeve.
Consult shown in Figure 1, the device that automatically locks of the present utility model is made up of members such as a locating bush 1, a spring 2 and movable sleeves 3, locating bush 1 is for being nested with the hollow circular cylinder on handspike 4, its appropriate position perpendicular to axial direction wears a pin-and-hole 11, be set on pin-and-hole 11 and the handspike 4 on the cooresponding hole 41 by locating dowel pin 5, locating bush 1 is fixed on the handspike 4, and locating bush 1 lateral process is established a raised line 12.Movable sleeve 3 is nested with on locating bush 1, and its inboard is arranged with a strip groove 31 (as shown in Figure 3), and raised line 12 proper and on the locating bush 1 cooperates, and this cooperation makes movable sleeve 3 motion orientations; Place a spring 2 between movable sleeve 3 and the locating bush 1, and this spring 2 slightly is compressive state, on handspike 4 below the movable sleeve 3, establishes a location screw 7, make movable sleeve 3 sports limitings; On the movable sleeve 3 corresponding locking pole 6 establish one with another pipe box 32 of locating bush 1 parallel axes, and the mouth of pipe is established a gradient, when perambulator is propped use, handspike 4 drives the pipe box 32 of movable sleeve 3 automatically, gradient guiding by its mouth of pipe is nested with on locking pole 6, reach the locking purpose, as shown in Figure 2.Locking back perambulator skeleton pole is triangular in shape, and structure is firm, safe ready.
