Portable stretcher trolley with multi-directional rotating pulleys based on secondary injury of ordinary stretcher

technical field

The utility model relates to a stretcher vehicle, in particular to a portable stretcher vehicle based on the secondary injury of a common stretcher with multi-directional rotating pulleys.

Background technique

Stretchers, as the main moving equipment in the process of hospital rescue and patient transport, should first of all have the characteristics of dexterity and lightness and require fewer nursing staff, so that patients can be transferred in the shortest time; secondly, they should have better dynamic balance and Shock absorption, etc., to reduce or even eliminate the bumps and possible secondary injuries suffered by the patient during the push. The structure of the traditional emergency stretcher is relatively complicated, the appearance is relatively bulky, the shock absorption function is small, and when the patient is moved, it is easy to cause secondary injury to the patient.

Utility model content

The purpose of the utility model is to provide a portable stretcher trolley based on the secondary injury of the common stretcher with multi-directional rotating pulleys. The utility model can be pushed and used, and the patient can be easily placed on the sickbed without moving the patient, and has the characteristics of good dynamic balance and shock absorption.

The technical scheme of the utility model: based on the secondary injury of the ordinary stretcher, the multi-directional rotating pulley portable stretcher is characterized in that it includes a U-shaped base bracket, and the bottom of the U-shaped base bracket is provided with a plurality of universal wheels, and the U-shaped base bracket The two right angles of the two guide rails are respectively provided with upwardly extending guide rails. The chute of the two guide rails is set opposite to each other. There are bed board fixing frames inside the two guide rails. The bed board fixing frames are equipped with detachable bed boards. The hydraulic cylinder on the U-shaped base bracket, the telescopic rod of the hydraulic cylinder is provided with a supporting beam, and the two ends of the supporting beam are provided with lifting chains through gears. One end of the lifting chain is fixed on the bed plate fixing frame, and the other end is fixed on the U-shaped on the base stand.

In the aforementioned portable stretcher trolley based on the secondary injury of a common stretcher with multi-directional rotating pulleys, the detachable bed boards include two and a half bed boards, and the half bed boards are connected by fixing bolts.

In the aforementioned portable stretcher trolley based on secondary injuries of ordinary stretchers with multi-directional rotating pulleys, handles are provided at both ends of the bed board fixing frame.

Compared with the prior art, the utility model fixes the bed plate fixing frame on the U-shaped base bracket through the hydraulic lifting mechanism (the combination of the hydraulic cylinder, the supporting beam, the gear and the lifting chain), which can not only realize the lifting function, but also effectively The vibration energy input by the vehicle body is reduced, and the tolerance time for lowering the comfort limit is improved. The utility model has a certain cushioning performance, and reduces secondary injuries to patients, including bumps and the like. The utility model has the advantages that the stretcher vehicle is economical, convenient and fast, light in size, simple in structure, simple in operation, takes up few ambulance personnel, has high shock resistance, and has the advantages of little secondary damage to the wounded. The utility model can also place the patient on the sickbed easily and stably without moving the patient, and is convenient and quick to use.

Description of drawings

Fig. 1 is a structural representation of the utility model;

Figure 2 is a schematic diagram of the connection of the hydraulic cylinder.

The marks in the accompanying drawings are: 1-U-shaped base bracket, 2-bed board fixing frame, 3-guide rail, 4-gear, 5-hydraulic cylinder, 6-lifting chain, 7-removable bed board, 8-handle, 9- Fixed bolt, 10-universal wheel, 11-support beam, 12-telescopic rod.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and embodiments, but it is not used as a basis for limiting the utility model.

Example. Based on the secondary injury of ordinary stretchers, the multidirectional rotating pulley portable stretcher cart is composed as shown in Figures 1 and 2, and is characterized in that it includes a U-shaped base bracket 1, and the bottom of the U-shaped base bracket 1 is provided with a plurality of universal wheels 10. The two right angles of the U-shaped base bracket 1 are respectively provided with upwardly extending guide rails 3, the chute of the two guide rails 3 is arranged oppositely, the two guide rails 3 are provided with a bed board fixing frame 2, and the bed board fixing frame 2 is provided with a movable Disassemble the bed board 7, a hydraulic cylinder 5 fixed on the U-shaped base bracket 1 is arranged between the two guide rails 3, a supporting beam 11 is arranged on the telescopic rod 12 of the hydraulic cylinder 5, and the two ends of the supporting beam 11 are provided with gears 4 Lifting chain 6, one end of lifting chain 6 is fixed on the bed board fixed frame 2, and the other end is fixed on the U-shaped base support 1.

The detachable bed board 7 includes two half bed boards, which are connected by fixing bolts 9 between the half bed boards.

Both ends of the bed board fixing frame 2 are provided with handles 8, which are convenient for lifting the bed board fixing frame 2 and are convenient to use.

When the utility model is in use, since the two guide rails are fixed on one side of the U-shaped base bracket, and the bed board fixing frame is fixed on one side through the passage, the bed board fixing frame has a certain elasticity, which can buffer the vibration energy input by the vehicle body and improve the Reduce the tolerance time of the comfort limit. The up and down lift of the bed board fixing frame can also be realized through the expansion and contraction of the hydraulic cylinder (specifically, when the hydraulic cylinder is lifted and lowered, the supporting beam moves upward, and the lifting chain is driven on the gear, so that the bed board fixing frame moves upward after passing the limit of the guide rail. ), can facilitate the placement of the patient.

The utility model fixes the bed plate fixing frame on the U-shaped base bracket through the hydraulic lifting mechanism (combination of hydraulic cylinder, supporting beam, gear and lifting chain), which can not only realize the lifting function, but also effectively reduce the input from the vehicle body. Vibration energy, improved tolerance time lowering the comfort limit. The utility model has a certain cushioning performance, and reduces secondary injuries to patients, including bumps and the like. The utility model has the advantages that the stretcher vehicle is economical, convenient and fast, light in size, simple in structure, simple in operation, takes up few ambulance personnel, has high shock resistance, and has the advantages of little secondary damage to the wounded. The utility model can also place the patient on the sickbed easily and stably without moving the patient, and is convenient and quick to use.
