Description

Technical Field

[0001] This utility model relates to the field of handcart technology, and in particular to a handcart base and a handcart. Background Technology

[0002] Currently, trolleys are widely used in logistics, transportation and other fields. Existing trolleys include a base, handlebars and wheels. The base is provided with wheel holes and handle holes. The wheel holes are used to fix the wheels and the handle holes are used to fix the handlebars.

[0003] However, the load-bearing capacity of existing trolleys is fixed at the time of purchase. The load-bearing capacity of a trolley is determined by the base and wheels. With the same base thickness, a larger wheel load-bearing capacity will increase the load-bearing capacity of the trolley accordingly. With the same wheel load-bearing capacity, a larger base load-bearing capacity will also increase the load-bearing capacity of the trolley. However, there are often different load-bearing capacities required when using trolleys, so it is necessary to buy trolleys with different load-bearing capacities, which will result in higher purchase costs.

[0004] In the existing technology, different load-bearing capacities of trolleys need to be purchased separately when different load-bearing requirements are needed, which leads to higher purchase costs. Utility Model Content

[0005] In order to overcome the above-mentioned defects in the prior art, the present invention provides a handcart base and a handcart.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a handcart base and a handcart, including a base plate, two sets of fixing plates are symmetrically fixedly installed at the bottom of the base plate, a set of reinforcing ribs are detachably installed in the fixing plates, the upper end of the reinforcing ribs is in close contact with the base plate, two sets of sliding grooves are provided at both ends of the front side of the base plate, sliders are slidably installed in the sliding grooves, wheel seats are fixedly installed on the outside of the sliders, and a number of wheel holes are provided on the wheel seats.

[0007] Furthermore, mounting portions are provided on the front and rear sides of the reinforcing rib, and the mounting portions are slidably mounted on the fixing plate. The fixing plate and the mounting portions are fixedly mounted by bolts.

[0008] Furthermore, two sets of bidirectional lead screws are movably mounted inside the two sets of slide grooves on the same side, and two sets of sliders are movably mounted on the bidirectional lead screws.

[0009] Furthermore, a turntable is fixedly mounted on the outer side of the bidirectional lead screw.

[0010] Furthermore, the right end optical axis of the bidirectional lead screw is fastened by a fixing pin.

[0011] A handcart comprising a handcart base as described above.

[0012] The beneficial effects of this utility model are: when the trolley needs to carry heavy goods, the reinforcing rib 3 is installed between the two sets of fixed plates 2 to strengthen the base plate 1 and increase the load capacity. The rotating turntable 8 drives the bidirectional lead screw 7 to rotate, indirectly adjusting the relative position between the two sets of wheel seats 6 to suit different load conditions.

[0020] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0021] like Figure 1 and Figure 2 As shown, this utility model includes a base plate 1, with two sets of fixing plates 2 symmetrically fixedly installed at the bottom of the base plate 1. A set of reinforcing ribs 3 are detachably installed inside the fixing plates 2. Mounting parts 31 are provided on the front and rear sides of the reinforcing ribs 3. The mounting parts 31 are slidably installed on the fixing plates 2. The fixing plates 2 and the mounting parts 31 are fixedly installed by bolts 4. The upper end of the reinforcing ribs 3 is in close contact with the base plate 1. When the trolley needs to carry heavy goods, the reinforcing ribs 3 are installed between the two sets of fixing plates 2 to strengthen the base plate 1 and increase the load capacity.

[0022] like Figure 1, Figure 3 and Figure 4 As shown, two sets of sliding grooves 11 are provided at both ends of the front side of the base plate 1. Sliding blocks 5 are installed in the sliding grooves 11 and slide left and right. Bidirectional lead screws 7 are movably installed inside the two sets of sliding grooves 11 on the same side through bearings. A turntable 8 is fixedly installed on the outside of the bidirectional lead screw 7. Two sets of sliding blocks 5 are movably installed on the bidirectional lead screw 7. Wheel seats 6 are fixedly installed on the outside of the sliding blocks 5. Several sets of wheel holes 61 are provided on the wheel seats 6. The optical shaft at the right end of the bidirectional lead screw 7 is fastened by a fixing pin 9. The bidirectional lead screw 7 is driven to rotate by rotating the turntable 8, which indirectly adjusts the relative position between the two sets of wheel seats 6 to suit different load conditions.

[0023] When the trolley needs to carry heavier loads, the reinforcing ribs 3 are installed between the two sets of fixed plates 2 to strengthen the base plate 1 and increase the load capacity.
