The groove that frame lower end is adapted, the groove is provided with the through hole passed through for axle bolt, and the portal trestle lower end is embedded in groove
In, portal trestle upper end is provided with bearing block, and the connecting seat lower end is fixed with rotating shaft, and the connecting seat is arranged on by rotating shaft
Rotate and be connected on bearing block and with portal trestle, the outboard end of the portal trestle is connected with flexible restoring organ, the elasticity
The resetting-mechanism other end is connected with connecting seat lower end, is stretched out on the outside of the portal trestle and is provided with reinforcing plate, the elasticity
Resetting-mechanism is connected to the outer end of reinforcing plate.
Further, the flexible restoring organ is provided with two, and two flexible restoring organs are connected to portal trestle
Two outboard ends, the reinforcing plate is correspondingly provided with two.
Further, the connecting seat is provided with connection terminal, and the connection terminal is located at flexible restoring organ and door shape branch
One end away from rotating shaft above the connection end of frame.
Further, the flexible restoring organ is extension spring or gas spring.
The beneficial effects of the utility model are：The utility model is included under portal trestle, wheel body and connecting seat, portal trestle
End is articulated with wheel body both sides by axle bolt through wheel body center, and portal trestle upper end is provided with bearing block, and connecting seat lower end is consolidated
Surely there is rotating shaft, connecting seat is arranged on bearing block by rotating shaft and rotates and be connected with portal trestle, the outboard end of portal trestle connects
Be connected to flexible restoring organ, the flexible restoring organ other end is connected with connecting seat lower end, when the castor during traveling stress
And when making wheeling thereof, wheel body drives portal trestle to rotate, portal trestle and then drive flexible restoring organ rotation make elasticity multiple
Position mechanism is deformed, when external force disappears, and under the restoring force effect of flexible restoring organ, portal trestle drives wheeling thereof
Reset, so that castor continues to keep moving ahead, it is very easy to use；Simultaneously by setting fluted on gland, Men Xingzhi
So as to which gland is spacing in the lower end insertion groove of portal trestle when frame is hinged with wheel body so that gland will not when castor advances
Follow wheeling thereof, it is to avoid the axle bolt of connection gland and portal trestle because being crossed quick-wearing by gland pivoting friction so that
Avoid castor to scrap ahead of time caused by axle bolt rapid wear, reduce the use cost of castor.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 another angle schematic diagram；
Fig. 3 is the connection diagram of gland and wheel body.
Embodiment
Referring to figs. 1 to Fig. 3, it is of the present utility model it is a kind of can Rapid reset castor, including portal trestle 2, wheel body 1 and even
Joint chair 3, the lower end of portal trestle 2 is articulated with the both sides of wheel body 1 by axle bolt 6 through the center of wheel body 1, and the both sides of wheel body 1 are set
There is gland 5, the gland 5 is provided with the groove 51 being adapted with the lower end of portal trestle 2, and the groove 51 is provided with for axle bolt 6
The through hole 52 passed through, the lower end of portal trestle 2 is embedded in groove 51, and the upper end of portal trestle 2 is provided with bearing block 21, connection
3 lower ends of seat are fixed with rotating shaft 31, and connecting seat 3 is arranged on bearing block 21 by rotating shaft 31 and rotates and be connected with portal trestle 2, door
The outboard end of shape support 2 is connected with flexible restoring organ 4, and the other end of flexible restoring organ 4 is connected with the lower end of connecting seat 3, when this
Castor is when stress during traveling rotates wheel body 1, and wheel body 1 drives portal trestle 2 to rotate, portal trestle 2 and then drive
Flexible restoring organ 4 is rotated, and is deformed flexible restoring organ 4, when external force disappears, in the reply of flexible restoring organ 4
Under power effect, portal trestle 2 drives wheel body 1 to rotate reset, so that castor continues to keep moving ahead, it is very easy to use.It is logical
Cross and set fluted on gland, so that gland be limited in the lower end insertion groove of portal trestle when portal trestle is hinged with wheel body
Position so that gland will not follow wheeling thereof when castor advances, it is to avoid connect the axle bolt of gland and portal trestle because by
Gland pivoting friction and cross quick-wearing so that avoid castor caused by axle bolt rapid wear ahead of time scrap, reduce castor
Use cost.
In the utility model, the outside of portal trestle 2, which stretches out, is provided with reinforcing plate 22, the flexible restoring organ
4 are connected to the outer end of reinforcing plate 22, by being provided with the reinforcing plate 22 stretched out in the outside of portal trestle 2, while by elasticity
Resetting-mechanism 4 is connected to the outer end of reinforcing plate 22 so that when portal trestle 2 is rotated, the rotation amplitude of the outer end of reinforcing plate 22 compares
Greatly, and then the deflection for being connected to the flexible restoring organ 4 of the outer end of reinforcing plate 22 is made than larger, so as to produce than larger
Restoring force.
Specifically, in order that castor automatically replies more reliable, the flexible restoring organ 4 is provided with two, two
Flexible restoring organ 4 is connected to two outboard ends of portal trestle 2, and the reinforcing plate 22 is correspondingly provided with two, so that
It can all be acted on so that wheel body 1 turns left or turned right by the restoring force of flexible restoring organ 4, and then drive castor to automatically reset.
In the utility model, flexible restoring organ 4 is installed for convenience, the connecting seat 3 is provided with connection terminal 32, institute
State flexible restoring organ 4 to be connected on connecting seat 3 by connection terminal 32, in order that obtaining the deflection of flexible restoring organ 4 more
Greatly, the connection terminal 32 is located at flexible restoring organ 4 and one end away from rotating shaft 31 above the connection end of portal trestle 2, from
And make it that, when portal trestle 2 is being rotated, the deformation of flexible restoring organ 4 is bigger, so as to form bigger restoring force.
Preferably, the flexible restoring organ 4 is extension spring or gas spring, can be selected according to the specification size of castor
Suitable extension spring or gas spring.
It is described above, simply better embodiment of the present utility model, but the utility model is not limited to above-described embodiment,
