Description

Handcart with adjustable chassis

Technical Field

The utility model relates to a capital construction instrument field, especially a handcart with adjustable chassis.

Background

In the capital construction industry, building materials such as bricks, cement and sand need to be frequently carried, and in the process of carrying the building materials, the trolley is a transportation tool which is frequently applied. Traditional handcart chassis height is fixed, when carrying building material or the higher working face of other heavy objects, needs rely on the manpower to promote the take the altitude to the working face with the heavy object from the chassis of handcart, wastes time and energy, increases labour's cost, influences work efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model provides a handcart with adjustable chassis can promote the chassis height of handcart according to actual need to labour saving and time saving ground carries the heavy object of transporting to higher table surface, promotes work efficiency, reduces the labour cost. The utility model provides a technical scheme of handcart with adjustable chassis as follows:

the utility model provides a handcart with adjustable chassis, includes chassis, four wheels, four paws, pneumatic stem, tray, handrail frame, locking cross axle, mounting, fixed plate, four wheels rotate to be connected on four feet of four paws, four paws with pneumatic stem bottom threaded connection, the pneumatic stem with tray threaded connection, the tray with chassis threaded connection, one side that is close to back wheel on the chassis has set firmly two mountings, logical groove has been seted up on two mountings, the both ends of locking cross axle run through the logical inslot of two mountings respectively.

The tray comprises a tray main body and an adjusting rod, wherein the tray main body is provided with a hole, one end of the adjusting rod is bent to form a certain angle, and the bent end of the adjusting rod is arranged in the hole of the tray main body.

The working principle is as follows: the iron pipe of the pneumatic rod is filled with high-pressure gas, the through hole is formed in the piston, the gas pressure at two ends of the piston is equal, the sectional areas of two sides of the piston are different, one end of the piston is connected with the piston rod, the other end of the piston is not provided with the piston rod, pressure towards one side with a small sectional area is generated under the action of the gas pressure, namely the elastic force of the pneumatic rod, the lifting shaft is pressed after a person stands, the lifting shaft slowly descends, the speed is uniform, and the lowest point can be reached. The lifting shaft does not exert external force on the lifting shaft, and the lifting shaft rises to the highest point, so that the height of the chassis of the trolley is adjusted.

The utility model provides a pair of handcart with adjustable chassis can realize chassis altitude mixture control to conveniently promote the higher working face with transporting the heavy object, use manpower sparingly, reduce labour's cost, promote work efficiency.

Detailed Description

The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.

A handcart with an adjustable chassis comprises a chassis 5, four wheels 1, four claws 2, a pneumatic rod 3, a tray 4, a handrail frame 8, a locking cross shaft 7 and fixing pieces 6, wherein the four wheels 1 are rotatably connected to four feet of the four claws 2 through rotating shafts, the four claws 2 are in threaded connection with the bottoms of the pneumatic rod 3, the top of the pneumatic rod 3 is in threaded connection with the tray 4, a tray body 41 of the tray 4 is in threaded connection with the chassis 5, one side, close to the edge of the chassis 5, of the tray body 41 is provided with a through groove, one end of an adjusting rod 42 is bent at a certain angle, one bent end is inserted into the through groove formed in the tray body 41, one side, close to a rear wheel 1, of the chassis 5 is welded with two fixing pieces 6, the two fixing pieces are provided with through grooves, and two ends of the locking cross shaft 1 respectively penetrate through the through grooves of the two fixing pieces 6, the handrail frame is of a U-shaped tube structure, two open ends of the handrail frame 8 are respectively inserted into the grooves of the fixing pieces and are rotationally connected with the fixing pieces through fixing bolts, when the handcart is not used, the transverse shaft 7 can be pressed down and locked by force, the handrail frame 8 is moved downwards, and the handrail frame 8 rotates around the fixing bolts of the fixing pieces 6 until the handrail frame is in a horizontal state; when the hand cart is used, the locking cross shaft 7 is pressed downwards with the same force, the armrest frame 8 is moved upwards, and the armrest frame 8 rotates around the fixing bolt on the fixing piece until the armrest frame 8 is in a vertical state.

When the road surface is rugged and uneven, the height of the chassis 5 needs to be increased, the adjusting rod 42 is moved upwards, the high-pressure gas in the iron pipe of the pneumatic rod 3 pushes the piston to move upwards, the chassis 5 of the handcart is pushed to the maximum height, the proper height of the chassis is adjusted according to actual conditions, a user needs to stand on the chassis 5 of the handcart, the user stands on the handcart and presses the lifting shaft after the user stands, the lifting shaft descends gently until the chassis 5 is lowered to the proper height, and the adjusting rod 42 is loosened.
