Abstract
The utility model discloses a self-locking mechanism for a cart on an upslope. The self-locking mechanism comprises a cart body and an axle fixedly connected with wheels. A friction disk is fixedly connected to the axle. The friction disk is located between the wheels and close to one wheel. The friction disk comprises a left half part and a right half part. The end faces, where the left half part and the right half part are in contact, are respectively provided with an inverted-cone-shaped protruding block and an inverted-cone-shaped clamping groove, wherein each inverted-cone-shaped protruding block and the corresponding inverted-cone-shaped clamping groove are connected with each other in a clamped mode. A triangular support is connected to the cart body through bolts. A stop shifting block capable of abutting against the friction disk is hinged to the triangular support through a stop pin. The end, abutting against the friction disk, of the stop shifting block is a bevel tangent to the friction disk. A torsion spring is connected between the stop shifting block and the triangular support. A push rod is further hinged to the stop shifting block. The self-locking mechanism can prevent the cart from moving backwards in the process of going up a slope.
Description
Technical field
The utility model relates to a kind of safety self-locking mechanism, is specifically related to a kind of go-cart upward slope self-locking mechanism.
Background technology
At present, comprise that the go-cart that the employing man powers such as perambulator, shopping cart advance is to guarantee safety, be mostly provided with brake gear.But in the process of going up a slope, due to some extraordinary circumstances, user forgets apply the brakes device in the process of going up a slope, thereby make the reversing of go-cart Yan Po road, the article in go-cart or child's safety is produced and threatened.
Utility model content
Technical problem to be solved in the utility model is to provide and a kind ofly prevents that go-cart from moveing backward when going up a slope.
In order to solve the problems of the technologies described above, the utility model provides go-cart upward slope self-locking mechanism, comprises go-cart body and the wheel shaft that is fixedly connected with wheel, on described wheel shaft, is fixedly connected with friction disc, and friction disc is between wheel and near a wheel; Described friction disc comprises left-half and right half part, is equipped with the projection of back taper and the draw-in groove of back taper of mutual clamping on the end face contacting of left-half and right half part; On described go-cart body, bolt is connected with triangular supports, in triangular supports, by backing pin, is hinged with the stop shifting block that can offset with friction disc; One end that described stop shifting block and friction disc offset is the inclined-plane tangent with friction disc, is connected with torsion spring between stop shifting block and triangular supports, is also hinged with push rod on stop shifting block.
Adopt the go-cart upward slope self-locking mechanism of said structure, before going up a slope, unclamp push rod, make stop shifting block under the effect of torsion spring, its end face and friction disc offset.Now, if wheel rotates forward, friction wheel can rotate under the drive of wheel shaft; If wheel shaft rotates backward, on stop shifting block with the tangent inclined-plane of friction disc and friction disc week side under the effect of friction force, offset, thereby friction wheel cannot be rotated, then cause wheel shaft to rotate, wheel can only rotate forward.Even if run into extraordinary circumstances like this in upward slope process, cannot use or forget apply the brakes device, go-cart also can not be moveed backward, and can guarantee article in go-cart or child's safety.
As the utility model, further improve, one end that described stop shifting block and friction disc offset is provided with U-shaped groove, and U-shaped bottom portion of groove is embedded with friction rubber.Adopt after this structure, the U-shaped groove that one end that stop shifting block and friction disc offset is offered, in the time of can guaranteeing that stop shifting block and friction wheel offset, stop shifting block can not swing at friction wheel axial direction.The friction rubber that U-shaped bottom portion of groove is embedded, can extend service life of stop shifting block and friction disc, and the rubber that simultaneously rubs is convenient to change.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model go-cart upward slope self-locking mechanism embodiment;
Fig. 2 is the work schematic diagram of the utility model go-cart upward slope self-locking mechanism embodiment.
The specific embodiment
Reference numeral in Figure of description comprises: go-cart body 1, wheel 2, triangular supports 3, stop shifting block 4, friction disc 5, wheel shaft 6.
Below in conjunction with drawings and Examples, technical solutions of the utility model are described in further detail:
As depicted in figs. 1 and 2, the go-cart upward slope self-locking mechanism of a kind of embodiment of the utility model, comprises that go-cart body 1 and bolt are connected with the wheel shaft 6 of two wheels 2.On wheel shaft 6, be fixedly connected with friction disc 5, friction disc 5 is between two wheels 2 and near a wheel 2.Friction disc 5 comprises left-half and right half part, is equipped with the projection of back taper and the draw-in groove of back taper of mutual clamping on the end face contacting of left-half and right half part.On go-cart body 1, bolt is connected with triangular supports 3, in triangular supports 3, by backing pin, is hinged with the stop shifting block 4 that can offset with friction disc 5.Stop shifting block 4 is provided with U-shaped groove with one end that friction disc 5 offsets, and U-shaped bottom portion of groove is the inclined-plane tangent with friction disc 5, and U-shaped bottom portion of groove is embedded with friction rubber.Between stop shifting block 4 and triangular supports 3, be connected with torsion spring, on stop shifting block 4, be also hinged with push rod.
Before going up a slope, unclamp push rod, make stop shifting block 4 under the effect of torsion spring, its end face and friction disc 5 offset.Now, if wheel 2 rotates forward, friction wheel can rotate under the drive of wheel shaft 6; If wheel shaft 6 rotates backward, on stop shifting block 4, offset under the effect of friction force with tangent inclined-plane and the 5 weeks sides of friction disc of friction disc 5, thereby friction wheel cannot be rotated, then cause wheel shaft 6 to rotate, wheel 2 can only rotate forward.Even if run into extraordinary circumstances like this in upward slope process, cannot use or forget apply the brakes device, go-cart also can not be moveed backward, and can guarantee article in go-cart or child's safety.
The U-shaped groove that one end that stop shifting block 4 and friction disc 5 offset is offered, in the time of can guaranteeing that stop shifting block 4 and friction wheel offset, stop shifting block 4 can not swing to direction at friction wheel axle 6.
The friction rubber that U-shaped bottom portion of groove is embedded, can extend service life of stop shifting block 4 and friction disc 5, and the rubber that simultaneously rubs is convenient to change.
Below described is by reference to the accompanying drawings only preferred implementation of the present utility model; but the utility model is not limited to above-mentioned embodiment; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make various distortion and improvement, these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
