Description

Technical Field

[0001] The utility model relates to the technical field of ambulance stretchers, in particular to a stretcher platform convenient for movement. Background Art

[0002] The space in an ambulance is relatively tight. As the main bearing position for patients, the stretcher occupies a large amount of space inside the vehicle. And the common stretcher includes a stretcher platform fixed on the vehicle floor and a loading stretcher stacked on the stretcher platform. The loading stretcher is movable and is mainly used to transfer patients from outside the vehicle to inside the vehicle. Therefore, in order to create more operating space inside the vehicle, it is very necessary to make the stretcher platform movable horizontally inside the vehicle. In this way, when there is no patient, the stretcher platform can be moved horizontally and positioned on one side inside the vehicle, thereby greatly increasing the space on the other side inside the vehicle and facilitating the temporary placement of rescue equipment. When there is a patient in need of treatment, the stretcher platform together with the loading stretcher can be moved towards the middle position of the vehicle, increasing the convenience for doctors to treat patients and facilitating people to stand on both sides of the stretcher or place corresponding auxiliary equipment.

[0003] In the prior art, for the horizontal movement structure of the stretcher platform, positioning blocks are generally arranged at the middle position or both sides of the vehicle floor, and positioning grooves are arranged on the base of the stretcher platform. When the stretcher platform is located at the middle position inside the vehicle or moved to a certain side position, positioning is achieved by the positioning blocks at the corresponding positions being inserted into the positioning grooves. This structure has fixed positions for the horizontal movement and positioning of the stretcher platform. Once the space is insufficient due to the placement of equipment on both sides inside the vehicle body, the stretcher platform cannot be moved horizontally. This structure has great limitations and cannot achieve the stepless positioning of the stretcher's horizontal translation. Summary of the Utility Model

[0004] The problem solved by the utility model is to provide a stretcher platform convenient for movement, which can overcome at least one defect in the prior art, can achieve the stepless positioning of the horizontal translation of the stretcher platform inside the vehicle, that is, it can be translated to any position for positioning, and has a simple structure and convenient operation.

[0005] To solve the above problems, the utility model provides a stretcher platform convenient for movement, which includes a platform frame and two fixed bases. The two fixed bases are connected to the bottom plate of the ambulance. The two ends of the platform frame are respectively slidably connected to the two fixed bases along the width direction of the ambulance. Locking units for restricting the movement of the platform frame are arranged on both of the two fixed bases. An unlocking unit for controlling the locking or unlocking of the locking units to realize the locking and unlocking between the platform frame and the fixed bases is also arranged on the bottom plate.

[0006] The stretcher platform convenient for movement of the utility model has the following advantages compared with the prior art:

[0007] In the ambulance stretcher platform structure provided by the present utility model, by arranging two fixed bases at a certain distance on the ambulance floor, both ends of the platform frame are slidably connected to the two fixed bases respectively, and the platform frame can move when it is subjected to a lateral (width direction) pushing force. This structure realizes the sliding connection of the platform frame through the two fixed bases, while ensuring the smooth lateral movement of the platform frame, minimizing the volume of the base structure as much as possible. Additionally, in this structure, locking units are arranged on both fixed bases to lock the lateral movement of the platform frame, and correspondingly, an unlocking unit is arranged on the floor. The unlocking unit can control the locking or unlocking of the locking unit to achieve the locking and unlocking of the platform frame and the fixed base, that is, when it is necessary to laterally move the platform frame, only the unlocking unit needs to be operated to achieve unlocking, which is very convenient; and this structure is not limited by the lateral movement position of the platform frame and can be locked at any time during the lateral translation, that is, realizing the stepless positioning of the stretcher platform during lateral translation in the vehicle.

[0008] Furthermore, the platform frame includes a frame body assembled by four profiles and in a rectangular shape. The upper surfaces of the left and right profiles of the frame body are flush with the upper surface of the front profile, and the upper surface of the profile at the rear end of the frame body is lower than the upper surface of the front profile. Support plates are respectively connected to both sides in the width direction of the frame body, and the upper surfaces of the support plates are flush with the upper surface of the profile at the rear end of the frame body. In the above structure, through the different height settings of the support plates, the left and right side grooves, and the front profile, it is convenient for the movement of the boarding stop and can also realize the left and right position limitation, ensuring the smoothness of the boarding stretcher during movement.

[0009] As an improvement, limit baffles are detachably inserted at the rear ends of the two support plates. When the boarding stretcher moves forward from the rear of the platform frame to a set position, the two limit baffles are in contact with the rollers at the rearmost end of the boarding stretcher. In the above improved structure, the limit baffles are inserted at the rear ends of the support plates, combined with the front profiles of the platform frame to achieve the front and rear position positioning of the boarding stretcher.

[0010] Further improved, two sliding shafts are connected between two profiles in the length direction of the frame body. Sleeve tubes extending in the width direction of the platform frame are provided on both of the two fixed bases. Linear bearings extending in the length direction of the sleeve tubes are provided in both of the two sleeve tubes. The two sliding shafts are respectively in sliding fit with the inner holes of the linear bearings. Locking members of the two locking units respectively pass through the sleeve tubes and act on the outer walls of the sliding shafts. In the above improved structure, the movement of the sliding shafts has a certain guiding property through the arrangement of the sleeve tubes. In addition, linear bearings are provided between the inner walls of the sleeve tubes and the outer walls of the sliding shafts, reducing the sliding resistance and avoiding the generation of noise. On the other hand, after the linear bearings are provided, the inner walls of the sleeve tubes do not need to be finely processed, reducing the processing difficulty and the processing cost.

[0011] Furthermore, each of the two locking units includes a locking pin, an elastic member, and a sleeve with an open end. The open end of the sleeve is connected to the outer wall of the sleeve tube. An avoidance through hole is provided on the side wall of the sleeve tube. One end of the locking pin is in sliding fit in the sleeve, and the other end extends into the inner cavity of the sleeve tube through the avoidance through hole. An arc-shaped groove matching the outer shape of the sliding shaft is provided at the end of the locking pin. The elastic member is located between the locking pin and the bottom of the sleeve tube and is used to drive the locking pin to abut and lock on the outer wall of the sliding shaft. The unlocking unit is used to drive the locking pin to move towards the side away from the sliding shaft. In the above structure, under the action of the elastic member, the locking pin is driven to move towards the sliding shaft until the arc-shaped groove abuts and cooperates with the outer wall of the sliding shaft, preventing the platform frame from translating and realizing position locking. When unlocking, the locking pin can be driven to move towards the end away from the sliding shaft through the unlocking unit, which is very convenient.

[0012] Further improved, anti-slip gaskets are connected to one ends of the two locking pins close to the sliding shafts. In the above improved structure, the addition of the anti-slip gaskets can further increase the frictional resistance between the locking pins and the outer walls of the sliding shafts, improving the locking ability.

[0013] Furthermore, the unlocking unit includes two cable wires, a fixed block, and a handle. The fixed block is connected to the bottom plate. One ends of the two cable wires are respectively connected to one ends of the two locking pins close to the elastic members, and the other ends respectively slide through the fixed block and are connected to both ends of the handle. When in the locked state, the handle abuts against the outer wall of the fixed block. In the above structure, the unlocking unit has a simple structure. By pulling the handle, the synchronous movement of the two cable wires can be realized, and then the two locking pins are driven away from the sliding shaft, thus releasing the limit on the sliding shaft, and the platform frame can be easily translated.

[0014] Further improved, two guiding pulleys are arranged on the bottom plate near the two fixed bases, and one end of each of the two cables away from the handle is respectively wound around the two guiding pulleys. In the above improved structure, after the guiding pulley structure is set, the cable moves more smoothly during unlocking, and will not interfere with other components, and can ensure that the outer ends of the two cables are connected to the handle in parallel. During unlocking, by horizontally pulling the handle, the two cables can be driven to move simultaneously, realizing synchronous unlocking of the two lock pins, which is very convenient.

[0015] Other improved features and advantages of the present utility model will be elaborated in the subsequent specific embodiments, and part of them will become obvious from the description or be understood by implementing the present utility model. The objectives and other advantages of the present utility model can be achieved and obtained through the structures specifically pointed out in the description and the drawings.

[0025] The platform frame 1 in this embodiment includes two transverse profiles and two longitudinal profiles, and the two transverse profiles and the two longitudinal profiles are assembled into a rectangular frame body. The two transverse profiles of the frame body are flush with the upper end surfaces of the profiles at the front end (the end close to the ambulance cab), the upper end surface of the longitudinal profile at the rear end of the frame body is lower than the upper end surface of the longitudinal profile at the front end, and support plates 3 are respectively connected to both sides of the frame body in the width direction, and the upper end surfaces of the support plates 3 are flush with the upper end surfaces of the profiles at the rear end of the frame body; this structure, through the different height settings of the support plates 3, the left and right side grooves, and the front profiles, not only facilitates the movement of the boarding stopper but also can realize the left and right position limitation, ensuring the stability of the boarding stretcher during the movement process.

[0026] More specifically, in the above structure, see the attached Figure 1 and 2, a limit baffle 4 is detachably inserted at the rear end of each of the two support plates 3. Positioning insertion posts are provided at the lower ends of the two limit baffles 4, and positioning insertion holes are provided at the rear ends of the two support plates 3. The two limit baffles 4 realize the limitation of the boarding stretcher through the cooperation of the positioning insertion posts and the positioning insertion holes. When inserted and used, the upper ends of the limit baffles 4 are higher than the upper end surfaces of the two transverse profiles. When in use, first remove the two limit baffles 4. When the boarding stretcher is transferred from outside the vehicle to the platform frame 1 and moves forward from the rear of the platform frame 1 to the set position, insert the two limit baffles 4. The two limit baffles 4 are abutted against the rollers at the rearmost end of the boarding stretcher; in combination with the front profile of the platform frame 1, the front and rear position positioning of the boarding stretcher is realized.

[0027] In addition, in this embodiment, two sliding shafts 5 are connected between the two transverse profiles in the length direction of the frame body. Sleeve tubes 6 extending in the width direction of the platform frame 1 are provided on both fixed bases 2. Linear bearings 7 extending in the length direction of the sleeve tubes 6 are provided in both sleeve tubes 6. The two sliding shafts 5 are respectively slidably fitted in the inner holes of the two linear bearings 7; the locking members of the two locking units respectively pass through the sleeve tubes 6 and act on the outer wall of the sliding shaft 5 to realize the locking of the sliding shaft 5. After the sleeve tubes 6 are provided, the movement of the sliding shaft 5 has a certain guiding property, and linear bearings 7 are also provided between the inner wall of the sleeve tube 6 and the outer wall of the sliding shaft 5 to reduce the sliding resistance and avoid generating noise.

[0028] In this embodiment, referring to the appendix Figure 2 and 3 , both of the two locking units include a locking pin 8, an elastic member 9 and a sleeve 10 with one end open. The open end of the sleeve 10 is connected to the outer wall of the sleeve tube 6, and an avoidance through hole is opened on the side wall of the sleeve tube 6. One end of the locking pin 8 is slidably fitted in the sleeve 10, and the other end extends into the inner cavity of the sleeve tube 6 through the avoidance through hole. An arc-shaped groove matching the outer shape of the sliding shaft 5 is provided at the end of the locking pin 8; the elastic member 9 is located between the locking pin 8 and the bottom of the sleeve tube 6, and the elastic force of the elastic member 9 drives the locking pin 8 to abut and lock on the outer wall of the sliding shaft 5. The unlocking unit is used to drive the locking pin 8 to move towards the side away from the sliding shaft 5 to realize unlocking.

[0029] Preferably in this embodiment, the elastic member 9 is a cylindrical spring. The open end of the sleeve 10 is connected to the outer wall of the sleeve tube 6 by welding, and anti-slip gaskets 11 are connected to one ends of the two locking pins 8 close to the sliding shaft 5; after the anti-slip gaskets 11 are added, the frictional resistance between the locking pin 8 and the outer wall of the sliding shaft 5 can be further increased, and the locking ability can be improved.

[0031] See the appendix Figure 2 As can be seen, in this embodiment, the unlocking unit includes two cables 12, a fixing block 13 and a handle 14. The fixing block 13 is connected to the bottom plate. One end of each of the two cables 12 is respectively connected to one end of the two locking pins 8 close to the elastic member 9, and the other end respectively slides through the fixing block 13 and is connected to both ends of the handle 14. In the locked state, the handle 14 abuts against the outer wall of the fixing block 13. When unlocking, by pulling the handle 14, the synchronous movement of the two cables 12 can be realized, and then the two locking pins 8 can be driven to move away from the sliding shaft 5, so as to release the limit on the sliding shaft 5, and the platform frame 1 can be easily translated. In this structure, two guide pulleys 15 are arranged at positions on the bottom plate close to the two fixed bases 2. One end of each of the two cables 12 away from the handle 14 is respectively wound around the two guide pulleys 15. After the structure of the guide pulley 15 is set, the cable 12 moves more smoothly during unlocking, does not interfere with other components, and can ensure that the outer ends of the two cables 12 are connected to the handle 14 in parallel. When unlocking, by horizontally pulling the handle 14, the two cables 12 can be driven to move simultaneously, realizing the synchronous unlocking of the two locking pins 8, which is very convenient.

[0032] In some other embodiments, two or even more locking units can be respectively arranged on the two fixed bases 2, and the multiple locking units are circumferentially distributed along the sliding shaft 5 to better increase the locking force.
