Detailed Description

As shown in fig. 1-7, the low-noise handcart wheel comprises a wheel 1, a spoke 2, an intermediate shaft 3, a connecting shaft 4, a steering shaft 5, a locking piece 8, a connecting block 9 and a wheel connecting shaft 12.

Wheel 1 and one end fixed connection of spoke 2, the other end and the 3 fixed connection of jackshaft of spoke 2,

jackshaft

3 and 12 fixed connection of wheel connecting axle, steering spindle 5 and connecting block 9 fixed connection, connecting axle 4 and connecting block 9 fixed connection, locking piece 8 is connected with connecting axle 4, connecting

axle

4 and 12 swing joint of wheel connecting axle. The utility model discloses a two wheels 1, six spokes 2, two jackshafts 3 pass through 12 fixed connection of wheel connecting axle, a

wheel

1 and 2 fixed connection of three spokes, a

jackshaft

3 and 2 fixed connection of three spokes. The wheel connecting shaft 12 is rotatably connected to the connecting shaft 4. The spoke 2 comprises a lower section 21 and an upper section 22, wherein the lower section 21 is sleeved on the upper section 22 and is connected with the upper section 22 in a sliding manner. The lower section 21 is fixedly connected with the wheel 1, and the upper section 22 is fixedly connected with the intermediate shaft 3. A return spring 23 is arranged between the lower section 21 and the upper section 22, one end of the return spring 23 is fixedly connected with the upper section 22, and the other end is fixedly connected with the lower section 21. The connecting shaft 4 is provided with a damping rotating shaft 10, and the locking piece 8 is connected with the connecting shaft 4 through the damping rotating shaft 10. The outside of connecting block 9 is equipped with a through-hole, and the through-hole on the connecting block 9 is passed to the one end of locking piece 8, and the other end of locking piece 8 is between two wheels 1. A counter bore is arranged on the wheel connecting shaft 12, and one end of the locking piece 8 between the two wheels 1 is matched with the counter bore on the wheel connecting shaft 12. The locking plate 8 locks the wheel 1 by co-operating with a counter bore in the wheel connecting shaft 12.

The steering shaft 5 is connected with a fixing device 7 through a connecting bearing 6, and the fixing device 7 is fixedly connected with a trolley body 11. When the handcart works, an operator pushes the handcart body 11 to move forwards, the handcart body 11 drives the connecting bearing 6 to move forwards through the fixing device 7, the steering shaft 5 connected with the connecting bearing 6 also moves forwards, the steering shaft 5 drives the connecting block 9 to move, the connecting block 9 drives the connecting shaft 4 to move, the connecting shaft 4 drives the wheel connecting shaft 12 to move, the intermediate shaft 3 fixedly connected with the wheel connecting shaft 12 moves, the intermediate shaft 3 drives the spokes 2 to move, and the spokes 2 drive the wheels 1 to move.

In the moving process of the wheel 1, when the wheel meets uneven road surfaces or other obstacles, an upward force is applied to the wheel to drive the wheel 1 to move upwards, and the lower section 21 also moves upwards. Because the lower section 21 is sleeved in the upper section 22 and is connected in the upper section 22 through the return spring 23, and because the intermediate shaft 3 is fixed in the vertical direction, the upper section 22 fixedly connected with the intermediate shaft 3 is also fixed, the lower section 21 connected with the wheel on the side contacting with the ground is stressed to compress the return spring 23 upwards, and the lower section 21 slides inwards in the upper section 22; the lower section 21 connected with the wheel on the side not contacting with the ground is stressed to stretch the return spring 23, and the lower section 21 slides outwards in the upper section 22. The spokes 2 connected to the wheel 1 are compressed, and stretched, so that the intermediate shaft 3 is fixed in the vertical direction. Since the intermediate shaft 3 is fixed in the vertical direction, the height of the trolley body 11 remains unchanged. When the vibration disappears, the return spring 23 is required to restore the original state, and the spoke 2 is restored to the original length, so that the intermediate shaft 3 is fixed in the vertical direction. Since the intermediate shaft 3 is fixed in the vertical direction, the height of the trolley body 11 remains unchanged. The cart body 11 is constantly in a steady motion, and the noise generated in the operation of the cart is small.

When the direction of the handcart needs to be changed in the moving process, an operator pushes the handcart body 11 to change the moving direction, the connecting bearing 6 is connected with the fixing device 7, the connecting bearing 6 is connected with the steering shaft 5, the moving direction of the steering shaft 5 is unchanged when the direction of the handcart body 11 is changed, and when the operator pushes the handcart body 11 to continue moving towards the changed direction, the moving direction of the steering shaft can be automatically adjusted after the steering shaft is stressed, and the wheels 1 are driven to roll.

The locking piece 8 is connected with the connecting shaft 4 through a damping rotating shaft 10, one end of the locking piece 8 is arranged outside the connecting block 9, and the other end of the locking piece is arranged between the two wheels 1. The wheel connecting shaft 12 is provided with a counter bore, and one end of the locking sheet 8 in the two wheels 1 is matched with the counter bore on the wheel connecting shaft 12. When the handcart need not the during operation, only need to lift the one end of locking plate 8 in wheel 1 outside, locking plate 8 is rotatory upwards in the one end atress of wheel 1 outside, other end in wheel 1 inside is rotatory downwards, when locking plate 8 is rotatory to the hole on the wheel connecting axle 12 downwards in the one end of wheel 1 inside, locking plate 8 inserts the hole on the wheel connecting axle 12, locking plate 8 no longer rotates wheel connecting axle 12 and can not rotate, jackshaft 3 also can not rotate, because damping pivot 10 has the effect of pivot dynamics decay, under the condition of not exerting force, locking plate 8 can not rely on self gravity to resume original state, can only maintain current state unchangeably, therefore wheel 1 can not rotate. When the handcart is in operation, only one end of the locking piece 8 outside the connecting block 9 needs to be stepped on, one end of the locking piece 8 outside the connecting block 9 is stressed to rotate downwards, one end of the locking piece 8 inside the two wheels 1 is stressed to rotate upwards, the locking piece 8 is pulled out of a hole in the wheel connecting shaft 12, and the wheels 1 can rotate.

The utility model discloses a spoke can contract, has the effect of buffering inhaling the shake, has reduced the noise that leads to because of the motion is unstable in the handcart working process produces vibrations. The handcart can flexibly turn according to actual working requirements, and meanwhile, wheels can be locked through the locking sheet, so that the wheels are prevented from rolling when the handcart does not work.
