Description

Locking mechanism and use method of a translational transfer device for the sick and wounded

technical field

The invention relates to a locking mechanism and a use method of a translational transfer device for the sick and wounded, belonging to the technical field of medical equipment.

Background technique

The patent with the authorized announcement number of CN205698269U discloses a transfer device for the wounded and the sick, and the patent application with the announcement number of CN105963089A discloses a translational transfer transfer device for the sick and the sick. The device as a whole is divided into two parts: transfer hospital bed and fixed hospital bed. Rails are installed at the lower parts of the two beds, and the bed boards are driven by the running motor to transfer the wounded through the docking of the two rails. It is mainly used to realize the safe and painless automatic transfer of the wounded. However, the translational transfer bed lacks the corresponding positioning and locking mechanism when the two beds are docked, and the rails cannot be docked quickly and accurately. Moreover, even after the position is calibrated, the position is easily moved during the transfer process, causing the rails to be misaligned, resulting in Failed transfer. Therefore, it is very necessary to design a locking mechanism and a method of use that can be used for the transfer device for the sick and wounded in translation.

The technical problem to be solved by the present invention is to provide a locking mechanism and a use method of a translational transfer device for the sick and wounded, so that the track can be positioned accurately and reliably when the transfer bed is docked. In addition, the operation should be simple and convenient, and the operation steps should be reduced as much as possible, so as to reduce the operation time and make the patient transfer quickly.

Detailed ways:

In order to make the object, technical solution and advantages of the present invention clearer, the present invention is described below through specific embodiments shown in the accompanying drawings. It should be understood, however, that these descriptions are exemplary only and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, and Fig. 11, this specific embodiment adopts the following technical scheme: it includes joystick 1 , limit block 2, return spring 3, bed frame 4, hospital bed U-shaped track 5, transfer bed U-shaped track 6 and locking mechanism 7, and the operating rod 1 is designed with a positioning rod 1-1 and a front shift fork 1-2 , rear shift fork 1-3, front shift fork groove 1-4, rear shift fork groove 1-5, the limit block 2 is fixedly connected on the bed frame 4, and the limit block 2 is designed with a left groove 2-1 , right groove 2-2, limit slideway 2-3, front operating lever hole 4-1, rear operating lever hole 4-2 are designed on the bed frame 4, locking mechanism 7 is made of lock body shell 7-1, Cover plate 7-2, lock head 7-3, lock core 7-4, torsion spring 7-5 and unlocking lever 7-6 are formed, and groove 7-7 is designed on the unlocking lever 7-6, and lock core 7-4 There is a protrusion 7-8 on the top, and a locking groove 7-9 is designed on the lock head 7-3. The lock body shell 7-1 is fixed on the U-shaped track 6 of the transfer bed, and the lock head 7-3 is fixed on the On the U-shaped track 5 of the hospital bed, the lock core 7-4 is connected to the lock body shell 7-1 by a pin, the unlocking lever 7-6 is sleeved on the lock core 7-4, and the protrusion 7-8 of the lock core 7-4 Located in the groove 7-7 of the unlocking lever 7-6, the cover plate 7-2 is fixedly connected with the lock body shell 7-1, and the operating lever 1 passes through the front operating lever hole 4-1 and the rear operating lever on the bed frame 4 Hole 4-2, front shift fork 1-2 and rear shift fork 1-3 on the joystick 1 are connected with corresponding unlocking lever 7-6 through front shift fork groove 1-4 and rear shift fork groove 1-5.

Further, there are two sets of locking mechanisms 7, which are fixedly connected to the two U-shaped rails 6 of the transfer bed respectively.

Further, the left groove 2-1 and the right groove 2-2 of the limiting block 2 are connected by a limiting slideway 2-3, and are respectively located at two ends of the limiting slideway 2-3.

Further, the return spring 3 is installed between the front shift fork 1-2 of the joystick 1 and the front operation hole 4-1 of the bed frame 4 .

The working principle of this specific embodiment is: when the wounded and sick need to transfer, firstly make the positioning rod 1-1 on the joystick 1 be in the left groove 2-1 of the limit block 2, and at this time push the transfer bed to When the bed approaches, the lock head 7-3 fixedly connected to the U-shaped track 5 of the bed enters the lock body shell 7-1 on the U-shaped track 6 of the transfer bed, and pushes the lock cylinder 7-4 to rotate counterclockwise. Design groove 7-7 on 7-6, therefore, now when lock cylinder 7-4 rotates, projection 7-8 on lock cylinder 7-4 can rotate in the groove 7-7 of unlocking lever 7-6 , does not come into contact with the unlocking lever 7-6, and has no power transmission effect, so it will not drive the rotation of the unlocking lever 7-6. When the U-shaped track 5 of the hospital bed is aligned with the U-shaped track 6 of the transfer bed, the lock head 7-3 completely enters the lock body shell 7-1. Since the lock head 7-3 is designed with a locking groove 7-9, the lock The core 7-4 rotates clockwise under the effect of the torsion spring 7-5 and enters the locking groove 7-9. At this time, the joystick 1 is still at the left groove 2-1 of the limit block 2, and because the left groove The limitation of 2-1 cannot be rotated, therefore, unlocking lever 7-6 is also unable to rotate at this moment, due to the effect of the protrusion 7-8 on the lock cylinder 7-4 and the groove 7-7 on the unlocking lever 7-6 , so that the lock core 7-4 cannot rotate clockwise, and because the contact surface on the right side of the lock head 7-3 and the lock core 7-4 is flat at this time, and under the action of the torsion spring 7-5, the lock core 7 -4 cannot be rotated counterclockwise, thus achieving lockup. When it needs to be separated after the transfer is completed, pull the joystick 1 outwards to overcome the elastic force of the return spring 3, so that the positioning rod 1-1 of the joystick 1 breaks away from the left groove 2-1 of the limit block 2 and enters the limit slideway 2 -3, then turn the joystick 1 to the right, so that the positioning rod 1-1 reaches the right groove 2-2 of the limit block 2, let go, and the joystick 1 enters the position of the limit block 2 under the action of the return spring 3 Right groove 2-2, in the process that joystick 1 rotates simultaneously, stir the unlocking lever 7-6 of locking mechanism 7 by front shift fork 1-2 and rear shift fork 1-3, the inside of unlocking lever 7-6 Groove 7-7 drives lock core 7-4 to overcome the torsional force of torsion spring 7-5 by protrusion 7-8 on the lock core 7-4, and because lock core 7-4 and lock head 7-3 contact part are half Therefore, when the operating rod 1 rotates, it can drive the lock cylinder 7-4 to rotate counterclockwise to realize unlocking.
