[0002] A hand truck is a tool used to transport goods. By using a hand truck, materials can be transferred between different locations to meet the needs of production, life and other aspects. During the transportation process, the vehicle will face various bumpy road conditions, so the clamp is also one of the commonly used tools for the transport truck.

[0003] A Chinese patent application, published as CN209492562U, provides a fixture positioning transport vehicle. The vehicle comprises a first frame and a second frame, arranged from bottom to top. The first and second frames are constructed from crossbeams and longitudinal beams. The second frame is provided with a movable track, extending along the longitudinal beams to enable the fixture to move along the track. An adjustment mechanism is provided between the second frame and the first frame to adjust the height of the second frame. This solves the problem of the transport vehicle height not being aligned with the slide height, resulting in complex and labor-intensive movement operations.

[0004] The above-mentioned transport cart has the effect of fast positioning of the clamps, but the types of items transported on the cart are different, so different clamps are also required to clamp the transported items. Therefore, an adjustable clamp switching transport cart is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide an adjustable clamp switching transport vehicle to solve the problem that the clamps of the existing transport vehicles cannot be switched, thereby making it difficult to conveniently transport diverse items.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable clamp switching transport vehicle, comprising a plate body, a hand pull rod and a threaded rod, a pulley, and a connecting rod. The hand pull rod is located on one side of the outside of the plate body and is fixedly connected to the plate body. The threaded rod passes through the upper and lower parts of the hand pull rod and is threadedly connected to the hand pull rod. There are two groups of pulleys, three groups of connecting rods, and a cross bar is provided between the two groups of pulleys. The cross bar is fixedly connected to the three groups of connecting rods. A bidirectional screw is provided at the bottom of the plate body. The bidirectional screw is rotatably connected to the plate body and the connecting rod located in the middle position. The bidirectional screw is threadedly connected to two groups of connecting blocks, and two groups of clamping rods are fixedly installed on the top of the two groups of connecting blocks.

[0007] Preferably, two groups of sliding grooves are provided through the upper and lower parts of the plate body, and the clamping rod passes through the two groups of sliding grooves.

[0008] Preferably, four groups of threaded rods 2 are provided through the upper and lower parts of the plate body, and the threaded rods 2 are movably connected to the plate body.

[0009] Preferably, a fixing sleeve is provided at the bottom of the plate body, two sets of transmission wheels and a set of transmission belts are provided in the fixing sleeve, and the transmission belts are located outside the transmission wheels.

[0010] Preferably, the two bottom ends of the threaded rod are fixedly connected to the transmission wheel, and the transmission wheel is movably connected to the fixed sleeve.

[0011] Preferably, the second threaded rod is externally threadedly connected to a connecting sleeve, the connecting sleeve is externally movably connected to the inner rod, and the outer rod is externally sleeved to the inner rod.

[0012] Preferably, a rotating rod is provided inside and outside the two groups of outer rods, the outer rods and the rotating rod are rotatably connected, and the rotating rod is fixedly connected to the plate body.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1) By setting up a bidirectional screw and a clamping rod, it is easy to clamp and transport the goods on the top of the transport vehicle, so that the goods can remain stable during transportation. When in use, first place the goods on the top of the plate, turn the bidirectional screw, and the clamping rod moves to clamp the goods above it. When unloading, turn the bidirectional screw in the opposite direction again, and then unload. This also makes loading and unloading more convenient.

[0015] 2) By setting the threaded rod 2, the outer rod, the inner rod, and the connecting sleeve, the transport vehicle can be used as a clamp to facilitate the transportation of tubular goods. When in use, the threaded rod 2 is directly rotated, and the threaded rod 2 drives the transmission wheel below it to rotate, and the transmission wheel drives the external rotating belt to rotate, and the transmission belt drives another set of transmission wheels to rotate, so that the two sets of threaded rods 2 can rotate at the same time. When the threaded rod 2 rotates, the connecting sleeve moves upward at the same time, so that the two sets of outer rods form an angle, so that this device can facilitate the transportation of tubular goods.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] Combine Figure 1 - Figure 5 An adjustable clamp switching transport vehicle includes a plate body 1, a hand rod 2, a threaded rod 3, a pulley 4, and a connecting rod 5. The hand rod 2 is located on the outer side of the plate body 1 and is fixedly connected to the plate body 1. The threaded rod 3 passes through the upper and lower parts of the hand rod 2 and is threadedly connected to the hand rod 2. There are two groups of pulleys 4 and three groups of connecting rods 5. A cross bar is provided between the two groups of pulleys 4, and the cross bar is fixedly connected to the three groups of connecting rods 5.

[0025] See Figure 2 and Figure 3 , it is further obtained that a bidirectional screw 9 is provided at the bottom of the plate body 1, and the bidirectional screw 9 is rotationally connected to the plate body 1 and the connecting rod 5 located in the middle position. The bidirectional screw 9 is threadedly connected to two sets of connecting blocks 7, and two sets of clamping rods 6 are fixedly installed on the top of the two sets of connecting blocks 7; two sets of sliding grooves 8 are opened through the upper and lower parts of the plate body 1, and the clamping rod 6 passes through the two sets of sliding grooves 8.

[0026] Specifically, when it is necessary to use this transport vehicle to transport goods, first place the goods on top of the plate body 1, and then rotate the bidirectional screw 9 to move the clamping rod 6, and the clamping rod 6 moves to clamp the goods, thereby facilitating the transportation of goods. At the same time, a threaded rod 3 is provided. When it is necessary to place the goods, rotate the threaded rod 3 so that the end of the threaded rod 3 contacts the ground, so that the transport vehicle can be parked more stably on the ground. When it is necessary to transport, twist the threaded rod 3 so that the end of the threaded rod 3 is off the ground.

[0027] Example 2

[0028] See Figure 4 and Figure 5, and on the basis of Example 1, it is further obtained that four groups of threaded rods 2 10 are provided through the upper and lower parts of the plate body 1, and the threaded rods 2 10 are movably connected to the plate body 1; a fixed sleeve 14 is provided at the bottom of the plate body 1, and two groups of transmission wheels 15 and a group of transmission belts 16 are provided in the fixed sleeve 14, and the transmission belts 16 are located outside the transmission wheel 15; the bottom end of the threaded rod 2 10 is fixedly connected to the transmission wheel 15, and the transmission wheel 15 is movably connected to the fixed sleeve 14; the external part of the threaded rod 2 10 is threadedly connected to the connecting sleeve 11, and the external part of the connecting sleeve 11 is movably connected to the inner rod 17, and the external part of the inner rod 17 is sleeved with the outer rod 12; a rotating rod 13 is provided inside and outside the two groups of outer rods 12, the outer rod 12 is rotatably connected to the rotating rod 13, and the rotating rod 13 is fixedly connected to the plate body 1.

[0029] Specifically, by providing the outer rod 12, the transportation of tubular goods can be facilitated. When in use, the threaded rod 10 is rotated to move the connecting sleeve 11 upward. At this time, the two sets of outer rods 12 rotate around the rotating rod 13 to form an angle, which facilitates the transportation of tubular goods.

[0030] In actual operation, first park the transport vehicle at the loading position, rotate the threaded rod 3 so that the bottom of the threaded rod 3 touches the ground, and then place the goods on the plate 1. After loading, rotate the two-way screw 9, the clamping rod 6 moves to clamp the goods, and then rotate the threaded rod 3 so that the bottom of the threaded rod 3 is off the ground. Finally, push the hand lever 2 of the transport vehicle to transport the goods to the destination.

[0031] When tubular goods need to be transported, the clamp can be switched for use. First, the threaded rod 2 10 is rotated. The rotation of the threaded rod 2 10 drives the transmission wheel 15 to rotate. The rotation of the transmission wheel 15 drives the transmission belt 16 to rotate. The transmission belt 16 drives another set of transmission wheels 15 to rotate, so that the two sets of threaded rods 2 10 can rotate at the same time. When the threaded rod 2 10 rotates, the connecting sleeve 11 moves outside the threaded rod 2 10, and the two sets of inner rods 17 rotate and extend to form an angle between the two sets of outer rods 12, which facilitates the placement of tubular goods.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
