Abstract

The utility model relates to a safe self-locking cart structure. The problem that cart self locking is hard is solved. The safe self-locking cart structure comprises a pushing handle which is connected with a pulling rod through a hinge connecting mechanism. The pulling rod is provided with a first cylinder block. The first cylinder block limits the lowest position of moving down of the pulling rod through the matching effect of the first cylinder block and a first limiting block connected with the cart body. A reset spring and a second cylinder block are arranged at the lower end of the pulling rod. When the pushing handle pulling rod is not under stress, under the effect of the reset spring, the pulling rod moves downwards. An inserting key is arranged at the bottom end of the pulling rod. A second limiting block connected with the cart body is arranged at the inserting key. Vertical moving of the inserting key is guaranteed. The inserting key can be inserted into a multi-groove cylinder which is connected with a wheel, and accordingly rotating of the wheel can be limited. The safe self-locking cart structure is reasonable, economical and applicable, when the pushing hand is not under stress, the wheel can be automatically locked, and safety is guaranteed.

Description

A kind of safe self-locking cart structure
Technical field:
The present invention relates to a kind of safe self-locking cart structure, can simple and effective self-locking go-cart, belong to civilian accessory equipment field.
Background technology
Go-cart often can be seen in life at ordinary times, for people's life brings a lot of convenience.In the time that go-cart does not stress, under the effect of gravity, can there is the situation of oneself slipping, some in particular cases this class slip great potential safety hazard, if on February 8th, 2012 is in Melbourne, AUS Railway station, there is perambulator and slide the thrilling accident of unexpected traveling fall rail.
The auto-lock function of go-cart is very important as from the foregoing, but more existing go-cart self-locking structures use the complex appts such as various sensors, master cock mostly, makes these structures be difficult to be accepted by masses because price is higher.Therefore, a kind of simple in structure, economical and practical go-cart self-locking structure of active demand.
Summary of the invention
The object of the invention is to solve the problem of go-cart self-locking, designed a kind of safe self-locking cart structure.
The present invention is achieved through the following technical solutions: safe self-locking cart structure comprises handle, handle is connected with pull bar by hinge connecting mechanism, pull bar is provided with the first cylindrical piece, under the first limiting stopper mating reaction that the first cylindrical piece is connected with vehicle body main body, can limit the extreme lower position that pull bar moves down; Pull bar lower end is provided with retracing spring and the second cylindrical piece, in the time that handle pull bar does not stress, will automatically move down at the effect lower link of retracing spring; Pull bar bottom is provided with slotting key, and slotting key position is provided with the second limiting stopper being connected with vehicle body main body, guarantees to insert the perpendicular movement of key; Slotting key can insert in multiple-grooved cylindrical piece, and multiple-grooved cylindrical piece is connected with wheel, thereby can limit the rotation of tire.The utility model is rational in infrastructure, economical and practical, gets final product automatic locking wheel in the time that handle does not stress, and guarantees safety.
Owing to adopting technique scheme, the advantage and the good effect that have are: in the time not stressing on handle, go-cart can automatic locking, compares existing go-cart self-locking device simple in structure, with low cost, but can reach same effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present invention.
In figure: 1-handle; 2-is hinged structure; 3-pull bar; 4-the first cylindrical piece; 5-the first limiting stopper; 6-retracing spring; 7-the second cylindrical piece; 8-inserts key; 9-the second limiting stopper; 10-multiple-grooved cylinder; 11-wheel; 12-vehicle body main body.
The specific embodiment
As shown in Figure 1, safe self-locking cart structure, a kind of safe self-locking cart structure, it is characterized in that: safe self-locking cart structure comprises handle (1), handle (1) is connected with pull bar (3) by hinge connecting mechanism (2), under the first limiting stopper (5) mating reaction that the first cylindrical piece (4) is connected with vehicle body main body (12), can limit the extreme lower position that pull bar (3) moves down; Pull bar (3) lower end is provided with retracing spring (6) and the second cylindrical piece (7), and pull bar (3) bottom is provided with slotting key (7), inserts key (7) position and is provided with the second limiting stopper (9) being connected with vehicle body main body (12), guarantees to insert the perpendicular movement of key (7); Insert key (7) and can insert in multiple-grooved cylindrical piece (10), multiple-grooved cylindrical piece (10) is connected with wheel (11).
When concrete enforcement, current push away or when post-tensioning handle (1), handle (1) leaves the slot on multiple-grooved cylinder (10) by the slotting key (7) on hinge connecting mechanism (2) drive pull bar (3), thus go-cart can be moved; In the time that handle (1) does not stress, under the effect of retracing spring (6), insert in the slot of key (7) reeve multiple-grooved cylinder (10), reach the effect of the rotation of limiting wheel.
