[0003] Generally, rollers are provided at the bottom of the tool cart to facilitate the transfer of the tool cart. When it is necessary to turn over the cart body to pour out the materials in the cart body, the staff will apply a horizontal component force to the vehicle frame when turning over the cart body. Since the vehicle frame contacts the ground through the rollers, the vehicle frame is likely to move, thus hindering the staff from turning over the cart body and reducing the unloading efficiency. Content of the Utility Model
[0004] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a tool cart with a turnover function, so as to solve the technical problems mentioned in the above background art.
[0005] The above technical purpose of the utility model is achieved through the following technical solutions:
[0006] A tool cart with a turnover function includes a bottom plate and a plurality of rollers rotatably connected to the lower half of the bottom plate. A cart body is arranged on the top of the bottom plate. One side bottom of the cart body is hinged to the top surface of the bottom plate. A control part is arranged on one side of the cart body. A cavity is formed in the bottom plate. A first piston is slidably connected in the cavity. A plurality of springs are fixedly connected between the first piston and the top wall in the cavity. A plurality of sliding strips are fixedly connected to the bottom of the first piston. The sliding strips slide through the lower half of the cavity.
[0007] Furthermore, the springs are always in a compressed state.
[0008] Furthermore, a plurality of anti-slip grooves are formed on the bottom surface of the sliding strips.
[0009] Further, the control part includes two cross bars fixedly connected to the upper half of one side of the cart body. The two cross bars are fixedly connected to a holding rod at their ends far away from the cart body. An accommodation cavity is formed in the holding rod. A second piston is slidably connected in the accommodation cavity. A moving plate is arranged between the holding rod and the cart body. A plurality of connecting rods are fixedly connected to the side of the moving plate close to the holding rod. The connecting rods slide through the holding rod and extend into the accommodation cavity. One end of the connecting rod located in the accommodation cavity is fixedly connected to the second piston. A hose is fixedly penetrated through the inner side wall of the accommodation cavity. The hose fixedly penetrates through the corresponding cross bar and the lower half of the cart body, and the end of the hose far away from the accommodation cavity fixedly penetrates through one side of the bottom plate and extends to the lower half of the cavity.
[0010] Further, the part of the cavity communicated with the hose, the part of the accommodation cavity communicated with the hose, and the hose are all filled with hydraulic oil.
[0011] Further, the plurality of sliding strips are arranged at equal intervals, and the weights of the plurality of sliding strips gradually increase along the direction close to the holding rod.
[0012] In summary, the present utility model includes at least one of the following beneficial technical effects:
[0013] 1. For the tool cart with a flipping function, when the tool cart is not pushed to move, the bottom surface of the sliding strip is in contact with the ground, and the friction between the sliding strip and the ground is large. Therefore, it is difficult for the bottom plate to slide. At this time, flipping the cart body will not cause the bottom plate to slide, thereby improving the unloading efficiency. When it is necessary to push the tool cart to move, only need to press the moving plate to drive the sliding strip to move upward, which will not affect the normal transfer operation of the tool cart;
[0014] 2. For the tool cart with a flipping function, the weights of the plurality of sliding strips gradually increase along the direction close to the holding rod. Therefore, the center of gravity of the vehicle frame is closer to the holding rod, preventing the situation that one side of the bottom plate is lifted due to the movement of the center of gravity of the cart body when flipping the cart body.

Detailed implementation manners
[0020] The following further elaborates on the present utility model in detail with reference to the accompanying drawings.
[0021] Embodiment:
[0022] Refer to Figures 1 to 3 , a tool cart with a flipping function disclosed by the present utility model includes a bottom plate 1 and a plurality of rollers 2 rotatably connected to the lower half of the bottom plate 1. A cart body 3 is arranged on the top of the bottom plate 1. The bottom of one side of the cart body 3 is hinged to the top surface of the bottom plate 1. A control part 4 is arranged on one side of the cart body 3. A cavity 5 is formed in the bottom plate 1. A first piston 6 is slidably connected in the cavity 5. A plurality of springs 7 are fixedly connected between the first piston 6 and the top wall of the cavity 5. The bottom of the first piston 6 is fixedly connected with a plurality of sliding bars 8, and the sliding bars 8 slide through the lower half of the cavity 5.
[0023] In this embodiment, the top of the cart body 3 is open, and tools, accessories and other items are placed in the cart body 3. The outer wall of the first piston 6 is in close fit with the inner wall of the cavity 5, and the fluid cannot pass through the first piston 6. Moreover, the sealing effect between the sliding bars 8 and the bottom plate 1 is good, and the fluid in the cavity 5 cannot be discharged from the side wall of the sliding bars 8.
[0024] When it is not necessary to push the tool cart to move, the bottom surface of the sliding bars 8 contacts the ground, and the friction between the sliding bars 8 and the ground is large. Therefore, it is difficult for the bottom plate 1 to slide. At this time, flipping the cart body 3 will not cause the bottom plate 1 to slide, thus improving the unloading efficiency.
[0025] When it is necessary to push the tool cart to move, the control part 4 is used to drive the sliding bars 8 to move upward. The sliding bars 8 no longer contact the ground, and the bottom plate 1 contacts the ground through the rollers 2. At this time, the tool cart can be easily pushed to move.
[0026] In a further preferred embodiment of the present utility model, as Figure 2 shown, the springs 7 are always in a compressed state.
[0027] In this embodiment, in the initial state, the sliding bar 8 is tightly pressed against the ground under the restoring force of the spring 7, which increases the friction between the sliding bar 8 and the ground and further improves the anti-slip effect of the bottom plate 1. In the initial state, the rollers 2 also contact the ground.
[0028] In a further preferred embodiment of the present utility model, as Figure 2 shown, a plurality of anti-slip grooves 9 are formed on the bottom surface of the sliding bar 8.
[0029] In this embodiment, the formation of the anti-slip grooves 9 further increases the friction between the sliding bar 8 and the ground.
[0030] In a further preferred embodiment of the present utility model, as Figure 1 and Figure 3 shown, the control part 4 includes two cross bars 41 fixedly connected to the upper half of one side of the carriage 3. The ends of the two cross bars 41 away from the carriage 3 are commonly fixedly connected with a holding rod 42. An accommodation cavity 43 is formed in the holding rod 42. A second piston 44 is slidably connected in the accommodation cavity 43. A moving plate 45 is arranged between the holding rod 42 and the carriage 3. A plurality of connecting rods 46 are fixedly connected to the side of the moving plate 45 close to the holding rod 42. The connecting rods 46 slidably pass through the holding rod 42 and extend into the accommodation cavity 43. The ends of the connecting rods 46 located in the accommodation cavity 43 are fixedly connected with the second piston 44. A hose 47 is fixedly penetrated through the inner side wall of the accommodation cavity 43. The hose 47 fixedly passes through the corresponding cross bar 41 and the lower half of the carriage 3, and the end of the hose 47 away from the accommodation cavity 43 fixedly passes through one side of the bottom plate 1 and extends to the lower half of the cavity 5.
[0031] In this embodiment, the hose 47 can be bent without hindering the rotation of the carriage 3. The holding rod 42 is cylindrically arranged, and the side of the moving plate 45 away from the holding rod 42 is arc-shaped, which is convenient for the staff to tightly hold the holding rod 42 and the moving plate 45. The second piston 44 is in close fit with the inner wall of the accommodation cavity 43, and the fluid cannot pass through the second piston 44.
[0032] When the staff wants to push the tool cart to move, the staff holds the holding rod 42 and the moving plate 45 and holds them tightly, driving the moving plate 45 to move towards the holding rod 42. The moving plate 45 drives the second piston 44 to move through the connecting rods 46. The second piston 44 pushes the air flow in the accommodation cavity 43 to be discharged through the hose 47. The air flow enters the lower half of the cavity 5, driving the first piston 6 to move upward. The spring 7 is further compressed. The first piston 6 drives the sliding bar 8 to move upward. At this time, only the rollers 2 contact the ground. While holding the holding rod 42 and the moving plate 45 tightly, the staff can push the holding rod 42, thereby driving the bottom plate 1 and the carriage 3 to move.
[0033] After the bottom plate 1 moves to a proper position, the operator releases the moving plate 45. Under the restoring force of the spring 7, the first piston 6 returns to its initial position, the sliding bar 8 moves downward to contact the ground, and the second piston 44 and the moving plate 45 also return to their initial positions under the action of air pressure.
[0034] In a further preferred embodiment of the present utility model, as Figure 2 shown, the part of the cavity 5 communicating with the hose 47, the part of the accommodating cavity 43 communicating with the hose 47, and the hose 47 are all filled with hydraulic oil.
[0035] In this embodiment, the movement of the second piston 44 drives the movement of the first piston 6 through the flow of hydraulic oil. Due to the incompressibility of the hydraulic oil, its transmission efficiency is higher.
[0036] In a further preferred embodiment of the present utility model, as Figure 2 shown, a plurality of sliding bars 8 are arranged at equal intervals, and the weights of the plurality of sliding bars 8 gradually increase along the direction close to the holding rod 42.
[0037] In this embodiment, the weights of the plurality of sliding bars 8 gradually increase along the direction close to the holding rod 42. Therefore, the center of gravity of the vehicle frame is closer to the holding rod 42, preventing the situation that one side of the bottom plate 1 tilts up due to the movement of the center of gravity of the hopper 3 when the hopper 3 is flipped.
[0038] The embodiments of the present specific implementation manners are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model shall be covered within the protection scope of the present utility model.
