The angle between the rail 301 and the first connecting rod 302 is greater than 90 °, and at this time, the angle between the connecting frame 304 and the first connecting rod 302 is less than 90 °. This ensures that the guard roller 303 moves in the direction of the support plate to push the rail 301 upward and simultaneously drive the first support plate 201 upward.
When the patient body contacts the protection roller 303 and generates pressure on the protection roller, the protection roller 303 is driven to move along the direction of the guide rod 308 and the guide hole 206, and when the protection roller 303 moves along the direction of the guide rod 308 and the guide hole 206, the second rotary connecting seat 307 connected with the protection roller 303 is driven to move along with the protection roller, and then the first connecting rod 302 connected with the protection roller is driven to rotate; the first connecting rod 302 generates a certain upward pressure on the railing 301, drives the railing 301 to move upwards compared with the second supporting plate 202, and drives the first supporting plate 201 to move upwards along the first sliding rail 101 and the second sliding rail when the railing 301 moves upwards, so that when the whole lifting guardrail is adjusted to be right, the height of the guardrail can be further increased by extruding the protective roller 303 through the body of a patient, and the patient is prevented from crossing the guardrail to achieve a good anti-falling effect; when the patient leaves the protection roller 303, the first support plate 301 is reset under the action of the tension spring 205, and the railing 301, the rotary connecting seat, the first connecting rod 302, the protection roller 303 and the like are all reset. In addition, the tension spring 205 also increases the buffering effect of the protection roller 303, so as to avoid the secondary injury caused by the rigid contact between the patient and the protection roller 303.
Referring to fig. 5, in this embodiment, the tension spring 205 is sleeved on the rail 301, so that the unit space can be reduced, the number of the protection rollers 303 can be increased, and in other embodiments, the tension spring 205 can also be directly connected with the first support plate 201 and the second support plate 202 without being sleeved on the rail 301, so long as a reasonable distance between the protection rollers 303 is ensured to avoid the patient from directly contacting the support plates.
