Description

Technical Field

[0001] The utility model relates to the technical field of carts, in particular to a hand-held double-wheeled cart. Background Art

[0002] A hand-held two-wheeled handcart is a device that is convenient for carrying and pushing items. Compared with traditional handcarts, a hand-held two-wheeled handcart is usually more flexible because it has only two wheels and can be more easily operated in narrow spaces or crowded environments. In addition, the armrest design makes pushing more stable and convenient.

[0003] After searching, a construction manual overturning bucket truck with publication number CN207955744U includes a wheelbarrow body, an equipment installation box is fixedly arranged on the main board of the wheelbarrow body, a guide slide bar is fixedly arranged at the front and rear symmetrical positions of the rod body of the central screw, and a rectangular movable support block is sleeved on the three rod bodies together, a large gear plate is meshed on the tooth edge of the bottom end of the small gear plate, and the plate body of the large gear plate is installed on the output end of the servo drive motor through a reducer, and a supporting connecting rod is correspondingly hinged on the seat body of the two No. 1 hinged seats, and a sand and stone storage box is fixedly arranged on the upper plate surface of the flip support plate. The scheme is simple and convenient to operate, which changes the disadvantage of heavy workload caused by the manual flipping operation of the traditional hand-over bucket truck, and there will be no accidental injury due to hand contact with stones, which guarantees the safety of workers to a certain extent. However, the above technical scheme still has the following shortcomings when it is actually used:

[0004] The prior art carts require workers to lift the handle upwards to tip over when unloading. The prior art integrates motors, gears and other mechanical devices to achieve automatic flipping and unloading of the cart bucket, which does improve the degree of automation of the operation and reduce the intensity of manual labor. However, in order to drive the cart bucket to flip, the additional motor, gear set, control system and related support structure significantly increase the overall weight of the vehicle, which not only directly reduces the vehicle's payload and affects the amount of cargo transported in a single trip, but also consumes more energy when pushed manually, increases the labor intensity of workers during transportation, reduces transportation efficiency, and also increases transportation costs. Secondly, in harsh working environments, such as humidity and dust, the reliability of the motor and electronic control system may be affected, increasing the failure rate, which will increase maintenance costs.

[0005] Therefore, it is necessary to design a hand-held two-wheeled cart to solve the above problems. Utility Model Content

A discharge port 3 is provided on the side wall of the cart 1 facing the dumping direction. The bottom of the cart 1 is in an inclined state. When unloading, the material can slide to the discharge port 3, and the staff does not need to tilt the device to reduce the The labor workload of the staff is reduced. A baffle 4 is provided in the discharge port 3. The baffle 4 and the trolley 1 are both made of steel material, which can ensure the overall stability of the device and improve the carrying capacity. The inner side of the discharge port 3 is rotatably connected with a rotating shaft 5. The baffle 4 is fixedly sleeved on the rotating shaft 5. A torsion spring 6 is provided between the rotating shaft 5 and the inner side of the discharge port 3. One end of the torsion spring 6 is fixed to the inner side of the discharge port 3, and the other end is fixed to the rotating shaft 5. The baffle 4 is reset. Two fixing components for fixing the baffle 4 are provided on the trolley 1.

[0025] Reference Figure 1-5 The fixing component includes a placement groove 8 opened on the inner side of the discharge port 3, and a card block 10 is slidably connected inside the placement groove 8. A spring 9 is provided between the card block 10 and the inner side of the placement groove 8. A card groove 7 corresponding to the placement groove 8 is provided on the side wall of the baffle 4. The spring 9 can push the card block 10 to move into the card groove 7 to fix the baffle 4. The fixing component also includes a driving member, which is used to control the movement of the card block 10.

[0026] Reference Figure 4 and Figure 5The driving member includes a pull rope 11 fixedly connected to the side wall of the card block 10 away from the card slot 7. The connection between the pull rope 11 and the card block 10 is located at the center of the side wall of the card block 10 to ensure the uniformity of the force applied by the pull rope 11 to the card block 10. The interior of the handle 2 is fixedly connected with a fixing plate 12 and a fixing plate 2 14. A connecting cavity is provided in the cart 1, and the pull rope 11 can extend to the interior of the handle 2 through the connecting cavity. A pressing plate 15 is provided between the fixing plate 12 and the fixing plate 2 14. A spring 2 16 is provided between the upper surface of the pressing plate 15 and the inner top surface of the handle 2. A push rod 17 is fixed on the pressing plate 15. The spring 2 16 is sleeved on the push rod 17, so that the pressure on the pressing plate 15 and the push rod 17 is stable, and the top end of the push rod 17 extends to the top of the handle 2. The longitudinal section of the push rod 17 is T-shaped. The structure is convenient for the staff to press and operate. A through hole 13 is opened on the fixing plate 12, and the pull rope 11 passes through the through hole 13, and the pull rope 11 is fixed to the side wall of the fixing plate 2 14, and the pressing plate 15 is located above the pull rope 11. In the initial state, the block 10 is located in the slot 7 under the action of the spring 19, the pull rope 11 is in a taut state, and the part of the pull rope 11 located in the handle 2 is in a horizontal position. When the pressing plate 15 presses the pull rope 11, the pull rope 11 will be pulled. The bottom surface of the pressing plate 15 is an arc-shaped structure, which reduces the wear of the pull rope 11 by the pressing plate 15. A roller is provided on the inner bottom surface of the through hole 13, and the bottom surface of the pull rope 11 is in contact with the roller. When the pull rope 11 is pulled and moved, the roller can reduce the friction between the pull rope 11 and the through hole 13, thereby extending the service life of the device.

[0027] The specific working principle of the utility model is as follows:

[0028] When it is necessary to unload materials, the staff presses the push rod 17 with both hands, and the push rod 17 drives the pressure plate 15 to move downward and presses the pull rope 11, so that the pull rope 11 is pulled, thereby driving the card block 10 to move and separate from the card slot 7. When the card block 10 moves back into the placement slot 8, the baffle 4 is no longer affected by the card block 10. Since the bottom of the cart 1 is in an inclined state, the materials in the cart 1 will slide toward the unloading port 3 and push the baffle 4, so that the rotating shaft 5 rotates and the baffle 4 is in an open state. When the material is dumped, under the elastic force of the torsion spring 6 and the self-closing of the baffle 4 Under the action of body gravity, the baffle 4 can be reset. At this time, the slot 7 can be aligned with the placement slot 8. The push rod 17 is released, and the block 10 can slide into the slot 7 under the elastic force of the spring 9 to fix the baffle 4. There is no need for the staff to lift the handle 2 upward to tip the entire cart 1, which reduces the labor intensity. Compared with the method of tipping the cart 1 driven by a motor, this design will not increase the weight of the cart 1, and the staff will not increase the load during transportation, which reduces the workload, while also ensuring transportation efficiency, and low transportation and maintenance costs.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
