The bottoms of the two first fixed blocks 4 are respectively fixed to the two universal wheels 6, so that the lifting structure can drive the universal wheel 6 to rise and fall.

[0042] The brake structure includes a locking mechanism, a pushing mechanism and a limiting mechanism. The locking mechanism includes a third connecting plate 22, a second fixed block 23, a motor 24, a worm 25, a worm wheel 26 and a connecting rod 27. The third connecting plates 22 are fixed on both sides of the bottom of the vehicle body 1. The two third connecting plates 22 are rotatably connected to the connecting rod 27 on the side close to each other. The second fixed blocks 23 are fixed at both ends of one side of one of the third connecting plates 22. The two second fixed blocks 23 are rotatably connected to the side close to each other. The motor 24 is fixed on one side of one of the second fixed blocks 23, and the output end of the motor 24 is fixed to the worm 25. The worm wheel 26 is fixed to the outer end of the connecting rod 27. The worm wheel 26 and the worm 25 are meshingly connected, so that the locking mechanism can limit the rotation of the connecting rod 27.

[0043] The pushing mechanism includes a cam 14, a tooth plate 18, a sliding sleeve 19, a connecting rod 20 and a return spring 21. The cam 14 is fixed to the outer side of the connecting rod 27, and connecting rods 20 are fixed on both sides of the bottom of the vehicle body 1. The outer sides of the two connecting rods 20 are slidably connected with the sliding sleeves 19, and the bottoms of the two sliding sleeves 19 are fixed with tooth plates 18. The outer sides of the two tooth plates 18 are sleeved and connected with return springs 21, and the tops of the two return springs 21 are fixed to the vehicle body 1, so that the pushing mechanism can drive the tooth plate 18 to rise and fall.

[0044] The limiting mechanism includes a second connecting plate 13, a rotating rod 15, a brake wheel 16 and a gear 17. Second connecting plates 13 are fixed on both sides of the bottom of the vehicle body 1. The inner sides of the two second connecting plates 13 are rotatably connected to the rotating rods 15. Brake wheels 16 are fixed on both sides of the rotating rod 15. A gear 17 is fixed on the outer side of the rotating rod 15 near the midpoint. The gear 17 and the toothed plate 18 are meshed and connected, so that the limiting mechanism can limit the rotation of the rotating rod 15.

[0045] The outer sides of the two brake wheels 16 are provided with anti-skid grooves, so that the brake wheels 16 can provide a braking effect for the device.

[0046] The utility model provides a new type of trolley. The device adopts the design of lifting structure, so that the trolley can easily cope with various terrains, including thresholds of different heights, ramps and uneven ground, which greatly improves the terrain adaptability of the trolley, so that medical staff can transport materials more conveniently and safely.

[0047] The device is designed with a brake structure that allows medical staff to quickly and stably fix the cart when it needs to be parked, reducing the risk of patient injury or equipment damage that may be caused by the cart sliding or moving. When the cart is parked on a slope or uneven ground, the brake structure can ensure that the cart remains stable and prevent it from tipping over or sliding.

[0048] The use process of a new type of trolley provided by the utility model is as follows: when the user pushes the device and encounters a ramp or an uneven ground, the user energizes the motor 9 to rotate, and the output end of the motor 9 drives the second bevel gear 12 to rotate. Since one side of the second bevel gear 12 is meshedly connected with the first bevel gear 11, the rotation of the second bevel gear 12 drives the first bevel gear 11 to rotate, thereby driving the screw rod 8 to rotate. Since the outer side of the screw rod 8 is threadedly connected with a lifting block 5, the rotation of the screw rod 8 drives the lifting block 5 and the T-shaped block 10 to slide and rise on one side of the vehicle body 1. The lifting of the lifting block 5 drives the first connecting plate 3 and the universal wheel 6 to rise and fall, thereby adjusting the position of the universal wheel 6 to keep the trolley balanced and reduce the shaking and tilting caused by the uneven ground, which helps to improve the stability of the trolley and ensure the safety of the patient during transportation; when braking is required When the cart is in use, the user energizes the motor 24 to rotate, and the output end of the motor 24 drives the worm 25 to rotate. Since the bottom of the worm 25 is meshedly connected with the worm wheel 26, the rotation of the worm 25 drives the worm wheel 26 to rotate, and then drives the connecting rod 27 and the cam 14 to rotate. The cam 14 can push the tooth plate 18 to move downward and restore the meshing connection with the gear 17, thereby preventing the rotating rod 15 and the brake wheel 16 from rotating. The outer side of the brake wheel 16 is provided with anti-slip grooves, which helps to reduce equipment damage that may be caused by the movement or sliding of the cart. This is of great significance for maintaining the integrity of medical equipment and extending its service life, and also reduces the operating costs of the hospital. In summary, the utility model can significantly improve the performance in terms of safety, stability, ease of operation, equipment protection and patient comfort, and is one of the important equipment that is indispensable to the emergency department.
