Abstract
The utility model discloses a rear wheel shaft turning locking mechanism for barrow, which comprises a skeleton main body with a rear wheel assembly, wherein the rear wheel shaft of the rear wheel assembly is pivoted on the skeleton main body and freely rotatable at pivot joint. The skeleton main body is provided with a locking hole; and the rear wheel shaft is provided with a locking mechanism telescopically fitted with or released from the locking hole to make the rear wheel shaft locked or turn. The utility model is installed at the connection part between the barrow rear wheel shaft and the skeleton main body, and can improve flexibility of turning of the barrow, reduce resistance, and improve barrow appearance.
Description
Technical field
The utility model relates to a kind of blocking device, particularly a kind of hand barrow hind axle Lenkradschlossvorrichtung of being located on the perambulator hind axle.
Background technology
Existing hand barrow, perambulator particularly, to change direction of travel when on rugged road surface, carrying out and all compare difficulty, needing go-cart experience preferably to be equipped with bigger implementation power could slowly turn to, turn to difficult problem in order to solve, existing hand barrow general using increases the implementation alerting ability that steering hardware wishes to improve car body on front vehicle wheel.But so just make the weight of wheel increase, heavy thereby car body becomes, and increase manufacturing cost, that can't really improve hand barrow again turns to flexibility ratio to reduce the implementation dynamics.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of can make wheel assembly turn to flexibly, simple in structure, easy hand barrow hind axle Lenkradschlossvorrichtung is installed.
A kind of hand barrow hind axle Lenkradschlossvorrichtung of the present utility model comprises the skeleton body of being with wheel assembly, it is characterized in that: wheel shaft is articulated on the skeleton body and also can freely rotates around articulating the position after the described wheel assembly; The skeleton body is provided with the blocking device that a lockhole and hind axle are provided with telescopically and lockhole clamping or get loose and make the hind axle locking or rotate.
Described blocking device comprises sleeve, be coated at sleeve afterbody and the switch handle that can rotate around sleeve and be located in the sleeve and can stretch out and snap in dead bolt in the lockhole from sleeve one end, sleeve interior surface is provided with jam spare, dead bolt is provided with and is positioned at jam spare top to limit the location fastener of dead bolt backway, be provided with an elastic body between jam spare and the location fastener, described switch handle is provided with the identical helical orbit of at least one rotation direction, and the dead bolt tail end is provided with the bayonet lock that can slide on helical orbit.Helical orbit is two, and bayonet lock is two, and each bayonet lock places on every helical orbit.Jam spare is an annulus.Described elastic body is a spring.
Described blocking device comprises also and is socketed on the bayonet lock and bayonet lock is positioned at limit base on the helical orbit that this limit base is coated at the sleeve afterbody and places on the helical orbit.
Described limit base is provided with the locating piece of band protuberance, offers on the sleeve afterbody for locating piece to move up and down to limit the grooved rail of limit base horizontal displacement.
Described blocking device also comprise one be fixed in the housing on the hind axle, described sleeve afterbody is located at outside the housing.
Described housing is made up of upper and lower cover, and being covered with on described increases the pulley that hind axle rotates alerting ability.
Described hind axle is a V-arrangement.
The utility model is installed in the junction of hand barrow hind axle and skeleton body, improves hand barrow car load steering flexibility, reduces the dynamics of go-cart, reduces and carries out difficulty, increases the aesthetic appearance of car body.
Description of drawings
Fig. 1 is the appearance assumption diagram of the utility model car body;
Fig. 2 is the assembling scheme drawing of blocking device.
The specific embodiment
As shown in Figure 1, the utility model comprises skeleton body 1 and wheel assembly 2, and wheel assembly 2 is made of hind axle and rear wheel.The V-arrangement hind axle is articulated on the skeleton body 1 and can freely rotates around articulating the position, and skeleton body 1 is provided with a lockhole, the blocking device 3 that hind axle is provided with telescopically and lockhole clamping or gets loose and make the hind axle location or rotate.
As Fig. 2, blocking device 3 comprises housing 31, sleeve 32, be coated at sleeve 32 afterbodys and the switch handle 34 that can rotate around sleeve 32, be located in the sleeve 32 and can stretch out and snap in dead bolt 33 in the lockhole from sleeve 32 1 ends, sleeve 32 inside faces are provided with jam spare, dead bolt 33 is provided with and is positioned at jam spare top to limit the location fastener 332 of dead bolt 33 backways, be provided with an elastic body between jam spare and the location fastener 332, this elastic body is a spring.Sleeve 32 afterbodys are located at housing 31 outside faces, and housing 31 is fixed on the hind axle.Housing 31 is made up of upper and lower cover, on be covered with and increase the pulley 36 that hind axle rotates alerting ability.Switch handle 34 is provided with the identical helical orbit of at least one rotation direction 341, and dead bolt 33 tail ends are provided with the bayonet lock 331 that slides on helical orbit 341.Helical orbit 341 is two, and bayonet lock 331 also is two, and each bayonet lock places on the helical orbit.Bayonet lock 331 is embedded in the limit base 35, and limit base 35 is socketed on sleeve 32 afterbodys and places on the helical orbit 341, which is provided with the locating piece of band protuberance, and corresponding the offering for locating piece of sleeve 32 afterbodys moves up and down to limit the grooved rail 322 of limit base 35 horizontal displacements.
When car body turns to, rotating switch handle 34, limit base 35 drive dead bolts 33 slide into the end of helical orbit 341 and block, dead bolt 33 withdraws from lockhole and is withdrawn into backward in the sleeve 32, locate fastener 332 simultaneously and move down compression spring 37, hind axle just can rotate around articulating the position like this, thereby can change the car body moving direction easily.When hind axle is locked, switch handle 34 is turned back, helical orbit 341 rotates and limit base 35 is motionless, be positioned at the other end of helical orbit 341 when bayonet lock 331, hind axle rotates when making dead bolt 33 be positioned at the lockhole below simultaneously, location fastener 332 is under the restoring force effect of spring 37, and promotion dead bolt 33 stretches out sleeve 32 and snaps in the lockhole, and hind axle is locked like this can not rotate.
