Detailed Description

The invention will be further described by means of specific embodiments and with reference to the accompanying drawings:

as shown in fig. 1: the cart device includes: bottom plate 1, gyro wheel 8 and handle 5, gyro wheel 8 sets up under bottom plate 1, handle 5 sets up perpendicularly in a side of bottom plate 1. The side edge of the bottom plate 1 adjacent to the side edge provided with the handle 5 is movably provided with an extension plate 2, and the extension plate 2 can be switched between a flat state and an upright state relative to the bottom plate 1, so that the trolley device can be switched between a flat state and a frame-type state. Can be used for carrying the block-shaped objects which exceed the bottom plate 1 and can also carry cylindrical and spherical objects which are easy to roll. Fig. 1 shows the trolley device in a flat position for carrying non-rolling, bulky objects of a size exceeding the floor 1.

As shown in fig. 6: the extension plate 2 includes a rectangular plate body 21 and a rotation shaft 22 fixed to one side of the plate body 21. The plate body 21 is formed by bending and welding steel plates, the rotating shaft 22 is made of round steel or a round pipe, and the rotating shaft 22 is welded on the long edge of the rectangular plate body 21. Two ends of the rotating shaft 22 exceed the plate body 21, and one end of the rotating shaft exceeds the plate body 21 more and is used for sleeving the spring 9; and the other end of the positioning plate exceeds the plate body 21 a little and is inserted into the rotating shaft hole 61 of the positioning plate 6. A lock hole 23 is also arranged at the side of the plate body 21. Plastic covers are sleeved on two ends of the rotating shaft 22.

As shown in fig. 2: the positioning plate 6 is fixed at one end of two side edges of the bottom plate 1 close to the handle 5 in a bolt connection or welding mode, a rotating shaft hole 61 and two positioning holes 62 are arranged on the positioning plate 6, and the included angle between the connecting line of the two positioning holes 62 and the rotating shaft hole 61 is 90 degrees. The end of the rotating shaft 22 of the extension plate 2, which exceeds the plate body 21 by a small amount, is inserted into the rotating shaft hole 61 and rotates in the rotating shaft hole 61, so that the lock hole 23 can be aligned with one of the two positioning holes 62, and the bolt 7 is sequentially inserted into the positioning hole 62 and the lock hole 23, so that the extension plate 2 is locked in a state of being flat with the base plate 1 or in a state of being upright with the base plate 1.

As shown in fig. 3: and a positioning plate 6 is fixed at one end of the two side edges of the bottom plate 1 far away from the handle 5 in a bolt connection or welding mode, and a rotating shaft hole 61 is formed in the positioning plate 6. The spring 9 is sleeved on one end of the extension plate 2, which exceeds the plate body 21, of the rotating shaft 22, until the rotating shaft 22 is inserted into the rotating shaft hole 61 of the positioning plate 6, and can rotate in the rotating shaft hole 61. At the same time, the spring 9 is compressed between the plate body 21 and the positioning plate 6, and the elastic force of the spring 9 pushes the plate body 21 toward the end where the handle 5 is arranged, so that the other end of the extension plate 2 abuts against the positioning plate 6, and the locking hole 23 abuts against the positioning hole 62, thereby ensuring that the bolt 7 can firmly lock the extension plate 2. When the extension plate 2 is converted from the state of being flat with the bottom plate 1 to the state of being upright with the bottom plate 1, the extension plate 2 is pushed forwards to press the spring 9, then the extension plate 2 is rotated by 90 degrees, and finally the bolt 7 is correspondingly inserted into the positioning hole 62. Thus, the small handcart can be converted from a full flat type into a frame type.

As shown in fig. 7: the positioning plate 6 is provided with a rotating shaft hole 61 and two positioning holes 62, and the included angle between the connecting line of the two positioning holes 62 and the rotating shaft hole 61 is 90 degrees.

As shown in fig. 4 and 5: the extension plates 2 on both sides of the base plate 1 are turned to an upright state perpendicular to the base plate 1, the lock holes 23 are aligned with the positioning holes 62 located at a high position, and the pins 7 are inserted into the positioning holes 62 and the lock holes 23 in order to lock the extension plates 2 at the upright position with respect to the base plate 1. The cart device is in a frame-like state for carrying cylindrical, spherical articles which are easy to roll.

In order to prevent the carried articles from rolling off, the side of the bottom plate 1 close to the handle 5 is vertically provided with the back baffle 3, the height of the back baffle 3 is h2, and the height of the back baffle h2 is about 15cm, so that the cost of the trolley is saved, and the weight of the trolley can be reduced.

The side edge opposite to the handle 5 arranged on the bottom plate 1 is vertically provided with the front baffle 4, the height of the front baffle 4 is h3, and the height h3 of the front baffle is about 10cm, so that articles can be prevented from rolling down, the cost of the handcart is saved, and the weight of the handcart can be reduced.

The handle 5 is composed of: two vertical rods 51 inserted or welded at two ends of one side of the bottom plate 1 and a plurality of cross rods 52 connecting the two vertical rods 51. The vertical rod 51 and the cross rod 52 can be made of steel pipes, the top of the vertical rod 51 is bent, an included angle between the bent vertical rod and the bent vertical rod is a handle oblique angle alpha, the handle oblique angle alpha is 15-30 degrees, so that the handle 5 inclines towards the direction back to the bottom plate 1, the height of the handle 5 is h1, and the height h1 of the handle is about 1.2m, so that the trolley is more convenient and labor-saving to push.

The roller 8 adopts a universal wheel with a brake, so that the trolley device is prevented from sliding when in static state, and the safety is ensured; when the handcart goes up and down a slope, the handcart is prevented from being out of control, so that the stress of workers is reduced.

When in use, the hand cart device is firstly placed close to the operation area. When cylindrical or spherical objects are conveyed, the extending plate 2 on one side of the cart is turned up to form a shape with baffles on three sides. When the trolley device is full of articles, the extension plate 2 on the other side of the trolley device is turned up. If the block-shaped objects are carried, the extension plate 2 is laid flat to obtain a larger bearing area.

In operation of the cart device, once the transport path is determined and any obstructions removed; secondly, wearing gloves, and tightly holding the handle 5 to obtain good friction force; thirdly, bending the knees and straightening the back, and using legs instead of the back to do pushing action; and fourthly, the walking robot needs to be pushed away, does not run, and can move backwards only when entering a narrow space.

In summary, the following steps: the utility model has the advantages that: the movable extension plate is arranged on the side edge of the bottom plate, so that the handcart device can be switched between a flat plate type state and a frame type state. The bearing area can be increased to carry the block-shaped objects which exceed the bottom plate; cylindrical and spherical articles which are easy to roll can be carried, and safe bearing is ensured; and the device can flexibly pass through some narrow work sites by shrinking the width of the device. The utility model discloses can be nimble warp, simple structure, preparation are easy, operation light, low cost.
