[0022] Example 1

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a construction cart, comprising a support frame 1, a shock-absorbing box 2 is fixedly connected to one side of the bottom of the support frame 1, fixed blocks 3 are fixedly connected to the inner sides of the shock-absorbing box 2, a fixed rod 4 is fixedly connected to the inner side of the fixed block 3, a slider 5 is slidably connected to the outer side of the fixed rod 4 extending to the outer side of the fixed block 3, a first spring 6 is arranged on the outer side of the fixed rod 4 and at one end of the slider 5, a slide plate 7 is slidably connected to the lower part of the shock-absorbing box 2, a pressure block 8 is fixedly connected to the top of the slide plate 7 and located between the two sliders 5, dampers 9 are arranged between the inner walls of the shock-absorbing box 2 on both sides of the top of the slide plate 7, a second spring 10 is arranged inside the damper 9, and shock-absorbing wheels 11 are symmetrically installed on both sides of the bottom of the slide plate 7 extending to the bottom of the shock-absorbing box 2.

[0024] In this embodiment, when the cart encounters a bumpy road section during driving, the impact force generated by the bump pushes the slide plate 7 to slide upward inside the shock-absorbing box 2 through the shock-absorbing wheel 11, and the slide plate 7 drives the pressure block 8 to move upward, thereby pushing the two sliders 5, so that the two sliders 5 slide outside the fixed rod 4 and move toward the inside of the fixed block 3, and at the same time squeeze the first spring 6, so that the first spring 6 generates deformation and buffering force, that is, the pressure block 8 provides a buffering force to the slide plate 7, and cooperates with the damper 9 and the second spring 10 to absorb most of the vibration force of the shock-absorbing wheel 11, thereby achieving the purpose of shock absorption, and effectively ensuring the stability of the cart during travel.

[0025] Example 2

[0026] like Figure 1-Figure 4 As shown, a wheel 12 is installed on the side of the bottom of the support frame 1 away from the shock-absorbing wheel 11, a bidirectional screw rod 13 is rotatably connected to the side of the inner part of the support frame 1 close to the wheel 12, the outer sides of the bidirectional screw rod 13 extend to the bottom of the support frame 1 and are threadedly connected to brake blocks 14, the bottom of the brake blocks 14 are fixedly connected to a rubber block, the outer side of the support frame 1 is fixedly connected to a motor 15 through a protective cover, the output end of the motor 15 extends to the inside of the support frame 1 and is fixedly connected to the bidirectional screw rod 13, the brake blocks 14 are slidably connected to the inner wall of the support frame 1, and the top of the support frame 1 is provided with A carriage 16 is arranged, and slide grooves 17 are provided on both sides of the outside of the support frame 1. Limit blocks 18 are fixedly connected to both sides of the outside of the carriage 16. The limit blocks 18 are slidably connected to the slide grooves 17. Bolts 19 are connected to the inner threads of the slide grooves 17 extending from one side of the top of the support frame 1. Handles 20 are fixedly connected to both sides of the outside of the carriage 16. A control switch 21 is installed on one side of the outside of the support frame 1. The motor 15 is electrically connected to the control switch 21. A hand push rod 22 is symmetrically fixedly connected to one side of the outside of the support frame 1 away from the carriage 16. The outside of the hand push rod 22 is provided with a knurled pattern.

[0027] In this embodiment, when encountering a downhill section, since the cargo is loaded in the carriage 16, it may slide down the slope under the action of gravity and inertia, making it impossible for human control. The motor 15 is started by controlling the switch 21, and the output end of the motor 15 drives the bidirectional screw 13 to rotate. The bidirectional screw 13 can drive the two brake blocks 14 to move toward the wheel 12 through the threaded connection relationship until the rubber block at the bottom of the brake block 14 is tightly attached to the outer wall of the wheel 12, thereby increasing the friction with the wheel 12 and slowing down the rotation speed of the wheel 12, which is convenient for the user to control and reduces the risk of use. When the carriage 16 needs to be taken out, loosen the bolt 19, hold the handle 20 and drag the carriage 16 to the outside until the limit block 18 slides out of the outside of the slide groove 17, and then the carriage 16 can be disassembled.

[0028] Working principle:

[0029] like Figure 1-Figure 4 As shown, when the cart encounters a bumpy road section during driving, the impact force generated by the bump pushes the slide plate 7 to slide upward inside the shock-absorbing box 2 through the shock-absorbing wheel 11, and the slide plate 7 drives the pressure block 8 to move upward, thereby pushing the two sliders 5, so that the two sliders 5 slide outside the fixed rod 4 and move inside the fixed block 3, and at the same time squeeze the first spring 6, so that the first spring 6 generates deformation and buffering force, that is, the pressure block 8 provides a buffering force to the slide plate 7, and cooperates with the damper 9 and the second spring 10 to absorb most of the vibration force of the shock-absorbing wheel 11, thereby achieving the purpose of shock absorption, effectively ensuring the stability of the cart when traveling, and when encountering a downhill section, due to the cargo loaded in the carriage 16, it may be due to gravity and inertia. The two-way screw rod 13 can drive the two brake blocks 14 to move toward the wheel 12 through the threaded connection relationship until the rubber block at the bottom of the brake block 14 is tightly attached to the outer wall of the wheel 12, thereby increasing the friction with the wheel 12 and slowing down the rotation speed of the wheel 12, which is convenient for users to control and reduces the risk of use. When the carriage 16 needs to be taken out, the bolt 19 is loosened and the handle 20 is held to drag the carriage 16 outward until the limit block 18 slides out of the outside of the slide groove 17, and the carriage 16 can be disassembled. Compared with traditional devices, the operation quality and use efficiency are greatly improved.
