In order to achieve the linkage effect when the guardrail 8 is inserted into the joint groove 501, the third chute 505 is slidably connected with the first push rod 507, and the outer end surface of the first push rod 507 It is level with the notch of connecting groove 501, in order to prevent the first push rod 507 from slipping out of the third chute 505, the inner end surface of the first push rod 507 is also provided with a second clamping plate 508, the width of the second clamping plate 508 is larger than The width of the first ejector pin 507, the third chute 505 is set as an outer groove and an inner groove, the size of the outer groove matches the size of the first ejector rod 507, and the size of the inner groove matches the size of the second clamping plate 508, which can To prevent the first push rod 507 from slipping out, a fourth spring 509 is pressed between the second clamping plate 508 and the inner groove to achieve the effect of elastic expansion and contraction. There are teeth on both sides of the first push rod 507, and the fourth chute 506 is slidingly connected with a second push rod 511, the second push rod 511 has the same structure as the first push rod 507, and the inner shaft of the gear groove is connected with a gear 510, and the gear 510 is connected to the first push rod 507 and the side of the second push rod 511. The teeth mesh with each other. When the guardrail 8 is inserted into the connecting groove 501, the guardrail 8 squeezes the first push rod 507, and the first push rod 507 slides into the third chute 505, which can drive the gear 510 to rotate so that the second push rod 507 The rod 511 slides outwards along the fourth chute 506, and there is a positioning rod 5111 on the end surface of the second ejector rod 511. The two groups of positioning rods 5111 correspond to the positions of the first positioning hole 8013 and the second positioning hole 8023 on the guardrail 8 respectively. The sizes match, and after the second push rod 511 slides outward, the positioning rod 5111 is inserted into the first positioning hole 8013 and the second positioning hole 8023, which can further limit the first railing 801 and the second railing 802 to prevent them from being pushed by the external force. Opening under the action loses the protective effect on the patient. At this time, the guardrail 8 is initially fixed on the docking device 5, but it will slide along the axis of the docking device 5, and the limit between the guardrail 8 and the backrest 401 has not yet been released. ; The linkage docking mechanism is also connected with a linkage unlocking mechanism for solving the above problems.

Concretely, as shown in Fig. 9 and Fig. 11, a dial slot, a third bar slot 513, and a fifth bar slot 525 are provided on the docking device 5, in order to release the limit on the first railing 801 and the second railing 802, dial Groove, the 3rd lever groove 513, the 4th lever groove 520 and the 5th lever groove 525, linkage unlocking mechanism are all provided with two groups and are arranged symmetrically, linkage unlocking mechanism has used driving lever 512, strike lever 514, pull rod 517, the fifth Spring 518 and unlocking lever 519, in order to facilitate unlocking the limit button in the unlocking hole, the fifth lever groove 525 is vertically opened on the docking device 5, the lower end of the fifth lever groove 525 communicates with the connecting groove 501, and the unlocking lever 519 Slidingly connected in the fifth rod slot 525, the two sets of unlocking rods 519 correspond to the first unlocking hole 8011 and the second unlocking hole 8021 on the guardrail 8, and their sizes match, in order to prevent the unlocking rod 519 from slipping out of the fifth rod slot 525, a third clamping plate 5191 is set on the upper end of the unlocking lever 519, its features and functions are the same as those of the second clamping plate 508, in order to prevent the unlocking lever 519 from falling under its own gravity, a spring buckle 5192 is installed on the third clamping plate 5191 , the fifth rod groove 525 is connected with the third rod groove 513 through the buckle groove, and the spring buckle 5192 is buckled on the buckle groove to form a limit, preventing the unlocking lever 519 from falling by itself, and the unlocking lever 519 is used to release the limit of the limit buckle. Therefore, the force exerted by the fall of its own gravity may not be enough to release the limit of the limit buckle, so the fifth spring 518 is pressed between the third clamping plate 5191 and the fifth rod groove 525 to increase the force of the unlocking rod 519. The force on the limit buckle is enough to release the limit; and at this time, it is necessary to set the structure for releasing the limit of the spring buckle 5192 to release the unlocking lever 519; The force applied when the guardrail 8 is inserted into the connecting groove 501 is used as power, the third rod groove 513 is connected with the fourth chute 506 through the dial groove, and the driving rod 512 is slidably connected in the dial groove, and one end of the driving rod 512 is connected to the connecting groove 501. The second ejector rod 511 is connected, and the other end slides in the third rod groove 513. Meanwhile, the third rod groove 513 is also slidably connected with a plunger 514. The front end of the plunger 514 is provided with a striker 522. The striker 522 is opposite to the spring buckle 5192. Drive the striker 514 to move through the driving lever 512, hit the spring buckle 5192 with the striker 522 to make it break away from the buckle groove, and release the unlocking lever 519; at this time, the part of triggering the linkage unlocking structure has been completed, but there will be retraction after the unlocking lever 519 is released. Requirements, this embodiment adopts the method of pulling back the unlocking lever 519, and connects the upper end of the fifth lever groove 525 with the outside world, and a pull rod 517 is installed on the third clamping plate 5191, and the pull rod 517 passes through the fifth lever groove 525 upwards. , by pulling the pull rod 517, the unlocking lever 519 can be pulled into the fifth lever groove 525, but at this time the striker 522 is still inserted in the buckle groove, and the spring buckle 5192 cannot be buckled into the buckle groove to form a limit, so it is necessary to move the lever 512 out of the way. In the case of moving, the plunger 514 is reset, so the sixth spring is pressed between the plunger 514 and the third rod groove 513 521, as shown in Figure 12, and on the lance 514, a rotary plate 515 is hinged, and a torsion spring is installed at the hinge, so that the rotary plate 515 maintains an angle of 30° with the lance 514 in the initial state, and the end surface of the rotary plate 515 and the dial The rod 512 is slidingly connected, and the end surface of the rotating plate 515 adopts an arc surface, and the center of the arc surface is located on the central axis of the hinge. In order to enable the driving rod 512 to apply a stable thrust, the driving rod 512 is connected to the upper half of the arc surface. As shown in Figure 13, the arc surface design here is to allow the rotary plate 515 to still rotate when the lever 512 is in contact with the rotary plate 515; Then, at this time, due to contact with the half part of the arc surface, the rotary plate 515 does not rotate in turn, and the driving rod 512 can apply a stable thrust to the rotary plate 515, that is, apply a stable thrust to the lance 514 to push the lance 514 to slide, compressing the sixth When the spring 521 needs to reset the ram 514 after releasing the unlocking lever 519, the sixth spring 521 cannot push the ram 514 to reset due to the blocking of the ram 512, and the rotary plate 515 needs to be rotated to remove the blocking of the ram 512. Here, the force when the unlocking lever 519 falls is used to rotate the rotating plate 515, because the unlocking lever 519 has begun to fall, indicating that the limit of the spring buckle 5192 has been released, and the lance 514 can be reset. A fourth rod groove 520 is opened between the three rod grooves 513. Because the unlocking rod 519 moves downward, the fourth rod groove 520 is set above the third rod groove 513. Because the position of the rotary plate 515 is low, the fourth rod The groove 520 is set as an L-shaped groove, and a pressure rod 516 is slidably connected in the fourth rod groove 520. Because the position of the rotary plate 515 is relatively biased, an L-shaped plate is added to the end of the L-shaped rod for the pressure rod 516, and the L-shaped rod One end is connected to the pull rod 517, and the other end is connected to the L-shaped plate. The end surface of the L-shaped plate is slidably connected to the upper top surface of the front end of the rotating plate 515. When the unlocking lever 519 drives the pulling rod 517 to move downward, the pulling rod 517 can drive the pressing rod 516 to fall, so that the rotating plate 515 can move downward. Plate 515 rotates, and it turns to level, as shown in Figure 14, at this moment, the rear end and the front end are higher than driving lever 512, and lance 514 resets under the action of the sixth spring 521, and after lance 514 moves, rotating plate 515 Leaving the pressing bar 516, reset under the action of the torsion spring, now the rear end of the rotating plate 515 is above the driving rod 512, and the driving rod 512 has been unable to block it. After crossing the driving rod 512, the rotating plate 515 is completely reset; When the second ejector rod 511 is reset, it drives the driving rod 512 to reset. When the driving rod 512 passes under the rotating plate 515, it squeezes the rotating plate 515 to make the rotating plate 515 rotate. After the driving rod 512 passes, the rotating plate 515 is under the action of the torsion spring. Reset; the unlocking rod 519 is inserted into the unlocking hole to finally position the guardrail 8 so that it will not slide; in order to facilitate the patient's standing, a handrail 502 is also provided on the docking device 5 .
