Abstract
The invention discloses a cart climbing self-locking mechanism which comprises a cart body and an axle fixedly connected with wheels. A friction disc is fixedly connected to the axle and located between the wheels and is close to one of the wheels. The friction disc comprises a left half part and a right half part, wherein the contact end faces of the left half part and the right half part are respectively provided with an inverted-conical protruding block and an inverted-conical clamping groove, and the inverted-conical protruding blocks and the inverted-conical clamping grooves are clamped and connected together. A triangular support is connected with the cart body through a bolt. A locking thumbing block which can abut against the friction disc is hinged to the triangular support through a stop pin. The end, abutting against the friction disc, of the locking thumbing block is an inclined face tangent to the friction disc. A torsional spring is connected between the locking thumbing block and the triangular support. A push rod is hinged to the locking thumbing block. The cart climbing self-locking mechanism can prevent cart backup when the cart climbs up.
Description
Technical field
The present invention relates to a kind of safety self-locking mechanism, be 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.
Summary of the invention
Technical matters to be solved by this invention 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 invention provides go-cart upward slope self-locking mechanism, comprise go-cart body and the wheel shaft that is fixedly connected with wheel, on described wheel shaft, be fixedly connected with friction disc, 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 present invention, 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 go-cart upward slope self-locking mechanism embodiment of the present invention;
Fig. 2 is the work schematic diagram of go-cart upward slope self-locking mechanism embodiment of the present invention.
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 solution of the present invention is described in further detail:
As depicted in figs. 1 and 2, the go-cart upward slope self-locking mechanism of one embodiment of this invention, 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 the preferred embodiment of the present invention; but the present invention 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 structure of the present invention; can also make various distortion and improvement, these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
