[0001] The utility model belongs to the field of rescue equipment, and specifically relates to an auxiliary positioning device for an electric stretcher, and also relates to rescue equipment for the electric stretcher. Background Art

[0002] A stretcher is generally a facility equipped in an ambulance. It meets the needs of the disease and is convenient for patients and the injured to lie down. When in use, medical staff need to move the stretcher out of the ambulance, transfer the patient or the injured to the stretcher, and then put the stretcher into the ambulance. The ambulance then sends the patient or the injured to the hospital for treatment.

[0003] In order to prevent the stretcher from shaking or sliding in the compartment of the ambulance, the prior art generally provides a stretcher fixture for fixing the stretcher in the compartment. For example, a Chinese patent with a publication number of CN104783975B discloses an auxiliary positioning device for fixing the stretcher on the vehicle, comprising: a base, a fixing groove is provided at the rear end of the base, a locking handle is hinged at the rear end of the base, a locking port is provided on the locking handle, a reset spring is provided between the locking handle and the base, and the reset spring makes the locking port be located at the fixing groove. In accordance with the position of the lock, the lock handle can be moved to make the lock mouth leave the fixed groove; a lock mechanism that can be linked with the lock handle is provided on the upper side of the front end of the base; the structure of the lock mechanism is: a lock seat is installed on the upper side of the front end of the base, a locking groove is provided in the lock seat, a locking block is hinged in the lock seat, a lock hook is provided on the top of the locking block, the lock hook can be locked with the locking groove, the bottom of the locking block is connected to the linkage rod, the other end of the linkage rod is hinged to the lock handle, and the elastic force of the reset spring makes the lock hook be located in the position of locking with the locking groove.

[0004] However, in actual use, since the positions of the locking handle and the locking mechanism are relatively fixed, the position accuracy of the cross bars and fixed columns at the front and rear ends of the stretcher is high, and medical staff need to carefully observe the alignment, which makes the operation difficult. Especially in an emergency, operational errors are likely to occur, resulting in the stretcher being unable to be accurately fixed. In addition, the operation is cumbersome, inconvenient, and time-consuming. Summary of the invention

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a new auxiliary positioning device for an electric stretcher.

[0006] The utility model also relates to an electric stretcher rescue device.

[0007] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0008] An auxiliary positioning device for an electric stretcher is arranged inside the ambulance compartment and relatively positions the electric stretcher and the ambulance compartment. The stretcher includes a stretcher body extending along the front-rear direction, a front wheel set and a rear wheel set arranged front and rear on the stretcher body, and a fixing rod arranged on the stretcher body. The auxiliary positioning device includes a positioning member and a fixing member fixedly arranged on the compartment floor. The positioning member is formed with positioning grooves matching with the front wheel set or / and the rear wheel set, and the fixing member has a clamping end cooperating with the fixing rod. The stretcher body moves along the front-rear direction and drives the front wheel set or / and the rear wheel set to be inserted into the positioning grooves, and the clamping end synchronously clamps and positions the fixing rod and drives the stretcher to be fixed in the compartment.

[0009] According to a specific implementation and preferred aspect of the present invention, there are two front wheel sets arranged side by side at intervals left and right, and there are two corresponding positioning grooves. When the stretcher body is pushed into the compartment from the rear to the front, the two front wheel sets are correspondingly inserted into the two positioning grooves. Herein, by synchronously positioning the two front wheel sets, it is beneficial to improve the stability of the stretcher.

[0010] Preferably, the two positioning grooves are symmetrically arranged left and right; and / or, each positioning groove is gradually narrowed from the rear to the front. Herein, during the movement of the stretcher, the positioning grooves can play a guiding role, realize synchronous deviation correction of the stretcher, and ensure that the front wheel sets are accurately inserted into the positioning grooves.

[0011] Specifically, the positioning member includes a left positioning rod and a right positioning rod extending front and rear and arranged side by side left and right. The front ends of the left positioning rod and the right positioning rod are respectively formed with a first bending portion extending forward and outward and a second bending portion bending backward from the front end of the first bending portion. A positioning groove is formed between the first bending portion and the second bending portion. Herein, the structure is simple and convenient for installation and implementation.

[0012] Furthermore, the length of the second bending portion is less than the length of the first bending portion. Herein, when correcting the deviation of the stretcher, it can avoid the second bending portion on the corresponding side from interfering with the stretcher.

[0013] Preferably, the positioning member further includes an auxiliary support rod connected between the left and right first bending portions and a connection module fixedly connected to the compartment floor. One end of the connection module is fixedly connected to the left positioning rod and the right positioning rod, and the other end is fixedly connected to the auxiliary support rod. Herein, the anti-deformation ability of the left and right positioning rods is improved, and the service life is prolonged.

[0014] According to another specific implementation and preferred aspect of the present invention, the fixing member is arranged on one side of the stretcher body, and the fixing rod is arranged on the side of the stretcher body close to the fixing member.

[0015] Preferably, the fixing member includes a fixing seat fixedly connected to the bottom plate of the carriage, and an adjusting rod extending in the front-rear direction and connected to the fixing seat, wherein the clamping end is provided at the front end or the rear end of the adjusting rod.

[0016] Specifically, the fixing seat is provided with an adjusting channel extending in the front-rear direction, and the adjusting rod is inserted into the adjusting channel. The fixing seat is provided with a plurality of connecting holes spaced up and down, and the adjusting channel is respectively connected to each connecting hole for up-and-down adjustment. Herein, the adjusting rod can be adjusted in height to match the fixing rods on stretcher trolleys of different heights, and at the same time, the structure is simple and the adjustment operation is convenient.

[0017] In addition, the clamping end includes a first clamping portion elastically connected to the front end of the adjusting rod, and a second clamping portion fixedly connected to the adjusting rod and spaced from the first clamping portion. The first clamping portion forms a hook portion extending circumferentially around the fixing rod, the second clamping portion is tangent to the side wall of the fixing rod, and the first clamping portion and the second clamping portion maintain an elastic tendency to approach each other to clamp the fixing rod.

[0018] Another technical solution of the present utility model is: an electric stretcher rescue device, which includes an electric stretcher and an auxiliary positioning device, wherein the electric stretcher cooperates with the auxiliary positioning device through the wheels and the fixing rods on the side of the stretcher body.

[0019] Due to the implementation of the above technical solutions, the present utility model has the following advantages compared with the prior art:

[0020] In the prior art, due to the relatively fixed positions of the lock handle and the lock catch mechanism, the position accuracy requirements for the cross bars and fixing columns at the front and rear ends of the stretcher trolley are high, and the operation difficulty is large. Especially in an emergency state, it is very easy to make an operation error, resulting in the inability to accurately fix the stretcher trolley; while in this application, the structure of the auxiliary positioning device of the electric stretcher trolley is integrally designed, and the deficiencies and defects of the prior art are ingeniously solved. After adopting this stretcher trolley auxiliary positioning device, the stretcher trolley is pushed into the carriage along the front-rear direction, so that the front wheel set or / and the rear wheel set are inserted into the positioning groove to achieve quick positioning, and the clamping end in the fixing member synchronously aligns and clamps the fixing rod, realizing the quick fixing of the stretcher trolley in the carriage. Therefore, compared with the prior art, on the one hand, the present utility model positions the wheels of the stretcher trolley through the positioning member, facilitating the medical staff to control the accurate alignment, and quickly fixes the stretcher trolley through the fixing member, greatly improving the success rate of accurate positioning of the stretcher trolley in the carriage; on the other hand, the operation is simple, convenient and efficient.
