For example, during use, there is a lack of a convenient braking mechanism, which requires additional operation to fix the conveyor cart when it reaches the designated location. The steps are relatively cumbersome. When the staff pushes the conveyor cart to the designated location and forgets to fix the conveyor cart, the conveyor cart may move due to uneven ground or inertia, posing certain safety hazards. At the same time, when the conveyor cart is moving, the cover on the top of the conveyor cart may open by itself due to movement or shaking, exposing the medical devices inside, affecting the sanitary quality of the medical devices. In addition, when the existing accessory conveying device is transporting large medical accessories, it may shake during the movement, causing the large medical devices to tilt or fall, causing damage to them.

[0035] It should be noted that: a slidably connected cover plate 5 is provided on the top of the transport vehicle body 1, which is used to close and protect the medical accessories stored inside. At the same time, a limiting structure 9 connected to the brake handle 4 is also provided inside the transport vehicle body 1, including a second steel rope 91, a fixed pulley, a tension spring 92, a column 93, a spherical bump 94 and a slot 95; when the medical staff holds the brake handle 4 to move the transport vehicle, the limiting structure 9 will be started at the same time, and the rotation of the brake handle 4 will pull the second steel rope 91, and the tension spring 92 will be stretched through the guiding effect of the fixed pulley. At the same time, the column 93 is driven to move. The movement of the column 93 causes the spherical protrusion 94 to pop out from the third circular hole 102 and engage with the card slot 95 at one end of the cover plate 5. In this way, even if the transport vehicle is bumped or vibrated during movement, the cover plate 5 can maintain a stable state, effectively preventing the intrusion of pollutants such as dust and bacteria, and ensuring the sanitary quality of medical supplies. A plurality of classification slots 15 are equidistantly provided on the top of the transport vehicle body 1, which is convenient for medical staff to classify and store different types of medical accessories, thereby improving work efficiency and convenience of use;

It can play a good fixing role when transporting large medical devices to avoid shaking during movement.

[0039] It should be noted that when the transport vehicle body 1 needs to transport large medical accessories, it is only necessary to lift the pallet 12 at the bottom thereof upwards, and the inner wall of the trapezoidal chute 184 will squeeze the trapezoidal slider 183, so that the trapezoidal slider 183 compresses the spring 182, so that the trapezoidal slider 183 disengages from the trapezoidal chute 184 and the pallet 12 is lifted. At this time, the operator can place the large medical accessories on the pallet 12, and then put the loaded pallet 12 back to the bottom of the transport vehicle body 1. Similarly, it is only necessary to place the trapezoidal slider 183 in the position corresponding to the trapezoidal chute 184 and press down. It can be easily connected, and then the strap 19 is passed around the large medical accessories and fixed in cooperation with the tensioning component 21. The design of the spring 213 in the tensioning component 21 allows the strap 19 to be firmly clamped by the press plate 212 when passing through the tensioning component 21 to prevent it from shaking around during movement. When the strap 19 needs to be loosened, only the press plate 212 needs to be gently pressed, and the press plate 212 is lifted upward to squeeze the spring 213. At this time, the strap 19 can be easily untied by lifting it upward, and then the press plate 212 is released and the press plate 212 will return to its original position under the action of the spring 213.

[0040] The working principle of the accessory conveying device provided by the utility model is as follows:

[0041] A handle 2 is fixed on one side of the transport vehicle body 1, which is convenient for medical staff to hold and push the transport vehicle. A first circular hole 10 is provided inside a side pillar where the handle 2 is connected to the transport vehicle body 1, for installing a transmission structure 8 related to the brake system. When the medical staff holds the brake handle 4, the brake handle 4 is connected to the brake plate 7 through the transmission structure 8 including a first steel rope 81, a fixed pulley, a spring 85 and a circular protrusion 86. The rotation of the brake handle 4 will pull the first steel rope 81, and the spring 85 will be compressed through the guiding effect of the fixed pulley, and the circular protrusion 86 will be driven to rise at the same time. The circular protrusion 86 is fixedly connected to the brake plate 7, so the brake plate 7 will also move up accordingly, thereby unlocking the universal wheel 6, so that the transport vehicle can move freely; when arriving at the designated location, the medical staff releases the brake handle 4, and the elastic force of the spring 85 will cause the circular protrusion 86 and the brake plate 7 to drop rapidly, locking the universal wheel 6, and preventing the transport vehicle from accidentally moving. This design not only improves the mobility of the transport vehicle, but also ensures its stability in a stationary state;

[0042] A slidably connected cover plate 5 is provided on the top of the transport vehicle body 1 for closing and protecting the medical accessories stored inside. At the same time, a limiting structure 9 connected to the brake handle 4 is also provided inside the transport vehicle body 1, including a second steel rope 91, a fixed pulley, a tension spring 92, a column 93, a spherical bump 94 and a slot 95, etc.; when the medical staff holds the brake handle 4 to move the transport vehicle, the limiting structure 9 will be started at the same time, and the rotation of the brake handle 4 will pull the second steel rope 91, and through the guiding effect of the fixed pulley, the tension spring 92 will be stretched, and at the same time, the column 93 will be driven to move. The movement of the column 93 will cause the spherical protrusion 94 to pop out from the third circular hole 102 and engage with the slot 95 at one end of the cover 5. In this way, even if the transport vehicle is bumped or vibrated during movement, the cover 5 can remain stable, effectively preventing the invasion of pollutants such as dust and ensuring the sanitary quality of medical supplies. When it is necessary to open the cover 5, it is only necessary to release the brake handle 4. At this time, the tension spring 92 will automatically retract without being affected by the tension, and the spherical protrusion 94 will slide down and disengage from the slot 95. At this time, the medical staff can easily open the sliding cover 5.

[0043] When the transport vehicle body 1 needs to transport large medical accessories, it is only necessary to lift the pallet 12 at the bottom thereof upwards, and the inner wall of the trapezoidal chute 184 will squeeze the trapezoidal slider 183, so that the trapezoidal slider 183 compresses the spring 182, so that the trapezoidal slider 183 disengages from the trapezoidal chute 184 and the pallet 12 is lifted. At this time, the operator can place the large medical accessories on the pallet 12, and then put the loaded pallet 12 back to the bottom of the transport vehicle body 1. Similarly, it is only necessary to place the trapezoidal slider 183 in the position corresponding to the trapezoidal chute 184 and press down once. It is easy to snap it in, and then the strap 19 is passed around the large medical accessories and fixed in conjunction with the tensioning component 21. The design of the spring 213 in the tensioning component 21 allows the strap 19 to be firmly clamped by the press plate 212 when passing through the tensioning component 21 to prevent it from shaking around during movement. When the strap 19 needs to be loosened, just press the press plate 212 lightly, and the press plate 212 will be lifted up to squeeze the spring 213. At this time, the strap 19 can be easily untied by lifting it up, and then the press plate 212 is released and the press plate 212 will return to its original position under the action of the spring 213.
