In some embodiments of the present invention, as shown in fig. 1 to 7, the upper lifting assembly 1 includes an upper lifting rod 11, both ends of the upper lifting rod 11 are rotatably connected to the upper cross rod 10 and the middle cross rod 30, respectively, the lower lifting assembly 2 includes a lower lifting rod 21, both ends of the lower lifting rod 21 are rotatably connected to the lower cross rod 20 and the middle cross rod 30, respectively, the synchronizing assembly 3 includes a first gear 31 and a second gear 32 engaged with each other, the first gear 31 is disposed at one end of the upper lifting rod 11 close to the middle cross rod 30, and the second gear 32 is disposed at one end of the lower lifting rod 21 close to the middle cross rod 30. Therefore, in the process that the upper cross rod 10 moves upwards, the two ends of the lifting rod 11 can rotate relative to the upper cross rod 10 and the middle cross rod 30 respectively, the lifting rod 11 can drive the first gear 31 to rotate in the rotating process, and the first gear 31 drives the second gear 32 to rotate when rotating, so that the lower lifting rod 21 can rotate along with the second gear 32, and the middle cross rod 30 and the upper cross rod 10 can synchronously lift.
Here, the rotation center of the first gear 31 coincides with the rotation center of the upper lift lever 11 with respect to the middle rail 30, and the rotation center of the second gear 32 coincides with the rotation center of the lower lift lever 21 with respect to the middle rail 30. And the rotation direction of the upper lift lever 11 is opposite to the rotation direction of the lower lift lever 21 due to the engagement of the first gear 31 and the second gear 32. Of course, it is understood that a driven gear may be disposed between the first gear 31 and the second gear 32 according to production requirements or use requirements, so that the rotation direction of the upper lifting rod 11 is the same as the rotation direction of the lower lifting rod 21, which is not limited herein.

In some embodiments of the present invention, the lifting fence 100 further comprises a driving assembly (not shown) disposed on the middle rail 30, the driving assembly being adapted to drive the first and second portions 301 and 302 to move in a direction away from or toward each other. Therefore, when the upper cross bar 10 and the middle cross bar 30 need to move from the folding position to the opening position, the driving assembly can drive the first portion 301 and the second portion 302 to move towards the direction away from each other, at this time, the middle cross bar 30 extends, and can drive the first sub-bar 111 and the third sub-bar 211 at the left end of the middle cross bar 30 to relatively rotate well, and the second sub-bar 112 and the fourth sub-bar 212 at the right end of the middle cross bar 30 to relatively rotate well, so that the upper cross bar 10 and the middle cross bar 30 can move to the opening position, similarly, when the upper cross bar 10 and the middle cross bar 30 need to move from the opening position to the folding position, it is only necessary to make the middle cross bar 30 do the shortening action through the driving assembly, which is not described herein.
Further, the driving assembly controls the extending action and the shortening action of the middle cross bar 30, and the middle cross bar 30 can be well controlled to stop at any extending position and then be kept at the changed position, so that the upper cross bar 10 and the middle cross bar 30 can be stopped at any height position, and different height requirements of the lifting guardrail 100 can be further met.
Further, when the driving assembly controls the middle cross bar 30 to extend to any position, a positioning assembly may be further provided to position the extended length of the middle cross bar 30 in real time, which is not limited herein.
In other embodiments of the present invention, as shown in fig. 1 to 7, the upper cross bar 10 and the middle cross bar 30 have an open position and a closed position in the lifting direction, and the lifting fence 100 further comprises a locking assembly 4, wherein the locking assembly 4 is adapted to lock the upper lifting assembly 1 and/or the lower lifting assembly 2, so that the upper cross bar 10 and the middle cross bar 30 are maintained in the open position or the closed position. That is, the upper cross bar 10 and the middle cross bar 30 may further have an open position and a closed position, as shown in fig. 5 to 7, when the upper cross bar 10 and the middle cross bar 30 are both located at the closed position, the upper cross bar 10 and the lower cross bar 20 are attached to each other in the up-down direction, the middle cross bar 30 is located at the rear side of the upper cross bar 10 and the lower cross bar 20 and located at the middle of the overall height of the upper cross bar 10 and the lower cross bar 20 in the up-down direction, and when the upper cross bar 10 and the middle cross bar 30 are both located at the open position, the locking assembly 4 may lock the upper lifting assembly 1, may also lock the lower lifting assembly 2, and may also lock the upper lifting assembly 1 and the lower lifting assembly 2 at the same time, so that the upper cross bar 10 and the middle cross.
Further, the locking assembly 4 includes a rigid hook 41 disposed at one end of the upper lifting assembly 1 facing the upper cross bar 10, and an elastic hook 42 disposed on the upper cross bar 10, the opening directions of the rigid hook 41 and the elastic hook 42 are opposite, and in the process that the upper cross bar 10 moves from the retracted position to the open position, the rigid hook 41 is adapted to elastically deform the elastic hook 42, and the elastic hook 42 is matched with the rigid hook 41 after being elastically deformed.
As shown in fig. 1 to 7, for example, a rigid hook 41 is formed at the upper end of the first sub-rod 111, during the rotation of the first sub-bar 111 relative to the upper crossbar 10, the rigid hook 41 can rotate around the rotation center of the first sub-bar 111, during the rotation of the rigid hook 41, the rigid hook 41 can abut against the lower end of the elastic hook 42, at this time, the rigid hook 41 continues to rotate, the elastic hook 42 can be elastically deformed, and when the elastic hook 42 is elastically deformed to a certain degree, the rigid hook 41 can be disengaged from the elastic hook 42, at this time, the rigid hook 41 is opposite to the opening of the elastic hook 42, at this time, if the upper cross bar 10 descends, the rotation direction of the rigid hook 41 can be changed, i.e. counter-rotating, whereby the rigid hook 41 and the elastic hook 42 can be snapped in, so that the upper crossbar 10 and the intermediate crossbar 30 are held in the open position.
Similarly, a rigid hook 41 is also formed at the upper end of the second sub-rod 112, and an elastic hook 42 is formed at the opposite position of the upper cross bar 10, and the operation process is completely consistent with the matching process of the rigid hook 41 at the upper end of the first sub-rod 111, and therefore, the detailed description thereof is omitted.
Further, the locking assembly 4 further comprises an unlocking member 43, the unlocking member 43 is disposed on the upper cross bar 10, and the unlocking member 43 is adapted to elastically deform the elastic hook 42 so as to disengage the elastic hook 42 and the rigid hook 41. Therefore, when the upper cross bar 10 and the middle cross bar 30 need to move from the open position to the closed position, the unlocking piece 43 can drive the elastic hook 42 to disengage the elastic hook 42 and the rigid hook 41, and at this time, the upper cross bar 10 and the middle cross bar 30 can descend by self gravity and can also be driven by the driving component, which is not limited herein.
In some embodiments of the present invention, in order to prevent the upper cross bar 10 and the middle cross bar 30 from colliding with each other or from being pinched during the movement of the upper cross bar 10 and the middle cross bar 30 from the open position toward the closed position, the buffer 5 may be disposed between the upper lifting assembly 1 and the upper cross bar 10, but it should be understood that at least one of the upper lifting assembly 1 and the middle cross bar 30, the lower lifting assembly 2 and the lower cross bar 20, and the lower lifting assembly 2 and the middle cross bar 30 may be disposed according to actual requirements, and is not limited herein. In the example shown in fig. 1 to 7, the buffer 5 can reduce the rotation speed of the first sub-rod 111, the second sub-rod 112, the third sub-rod 211 and the fourth sub-rod 212, so as to reduce the lifting speed of the upper cross rod 10 and the middle cross rod 30, and the reliability and the safety are high.
Further, the buffer member 5 may be an impact sleeve 51, as shown in fig. 1 to 7, the impact sleeve 51 is disposed on the bottom rail 20, and during the rotation of the third sub-rod 211, the lower end of the third sub-rod 211 may abut against the impact sleeve 51, so as to slow down the rotation speed of the third sub-rod 211 through the impact sleeve 51, and of course, the impact sleeve 51 may also limit the rotation angle of the third sub-rod 211. Similarly, in the rotation direction of the fourth sub-rod 212, the lower cross bar 20 is also provided with another anti-collision sleeve 51 matched with the fourth sub-rod 212, and the rotation speed of the fourth sub-rod 212 is slowed down through the anti-collision sleeve 51, so that the rotation angle of the third sub-rod 211 can also be limited.
In some examples of the present application, the buffer member 5 may also be a damper, a torsion spring, and the like, wherein the damper or the torsion spring may be disposed on the rotation axes of the third sub-rod 211 and the lower cross rod 20, the fourth cross rod and the lower cross rod 20, the first sub-rod 111 and the upper cross rod 10, and of course, the damper or the torsion spring may be disposed on all rotation axes of the lifting fence 100, and the present application is not limited thereto.
