The molding is made of a resin material to reduce the weight of the lift adjustment barrier 1.
In still another embodiment, the number of the first positioning holes 121 is only one, and is provided at the middle or top of the second longitudinal pipe 12 so that the lift adjustment barrier 1 is maintained in the unfolded state by inserting the first positioning pins 152 into the first positioning holes 121 when the lift adjustment barrier 1 is unfolded upward.
With continued reference to fig. 3 to 5, the first fixing sleeve 16 is attached to the bottom of the first vertical tube 11, and the first fixing sleeve 16 includes a first outer peripheral portion 161, a first protruding portion 162, and a first connecting wall 163 connecting the first outer peripheral portion 161 and the first protruding portion 162.
The first outer peripheral portion 161 is located between the outer wall of the first vertical tube 11 and the inner wall of the second vertical tube 12, serves to guide and lubricate the relative movement between the first vertical tube 11 and the second vertical tube 12, and plays a role in damping and noise reduction.
The outer wall surface of the first outer peripheral portion 161 is provided with a plurality of first outer ribs 164 extending in the longitudinal direction, and the first outer ribs 164 are movably in contact with the inner wall of the second vertical tube 12 to perform a guiding function and reduce the contact area between the first outer peripheral portion 161 and the second vertical tube 12 to reduce the sliding resistance between the first outer peripheral portion 161 and the second vertical tube 12.
Alternatively, the first fixing sleeve 16 is made of nylon (PA) material to further reduce sliding resistance between the first outer peripheral portion 161 and the second longitudinal pipe 12 and to reduce the weight of the elevation adjustment fence 1.
The first protrusion 162 is located inside the first longitudinal tube 11, supports the first positioning pin 152 and the first unlocking member 153, and provides a guide for movement of the first positioning pin 152 and the first unlocking member 153. The first projection 162 includes a first detent pin guide groove 165, a first unlocking piece guide groove 166, and a first limit groove 167.

Therefore, when the first unlocking member 153 moves downwards, the first inclined surface 154 can be pushed by the second inclined surface 155 to drive the first positioning pin 152 to retract so as to release the locking state of the first locking mechanism 15, so that the structure is simple, and the transmission is reliable.
The first unlocking member 153 is longitudinally movably inserted into the first unlocking member guide groove 166, and the first unlocking member guide groove 166 provides a guide for the movement of the first unlocking member 153. The first unlocking member 153 is telescopically connected with the first protruding portion 162 through a second spring 157, the second spring 157 is a compression spring, and two ends of the second spring abut against the first stopping portion 1531 of the first unlocking member 153 and the inside of the first protruding portion 162 respectively. The elastic force of the second spring 157 serves to extend the first unlocking member 153 upward so as to maintain the first locking mechanism 15 in the locked state when the first unlocking member 153 is not subjected to downward pressure.
The first unlocking member 153 is further provided with a first limiting boss 1532, the first limiting boss 1532 is used for being inserted into the first limiting groove 167 of the first protruding portion 162 to limit the longitudinal movement range of the first unlocking member 153, so that the first unlocking member 153 is prevented from being separated from the first protruding portion 162, and further, the maximum extension length of the first positioning pin 152 can be limited by the first unlocking member 153, so that the first positioning pin 152 is prevented from being separated from the first protruding portion 162.
With continued reference to fig. 3 to 5, the top of the second vertical tube 12 is fixedly connected with a first guiding sleeve 17, the first guiding sleeve 17 is disposed between the outer wall of the first vertical tube 11 and the inner wall of the second vertical tube 12, and is used for guiding and lubricating the relative movement between the first vertical tube 11 and the second vertical tube 12, and playing a role in damping and noise reduction, and the first guiding sleeve 17 is also used for stopping the first fixing sleeve 16 so as to prevent the first vertical tube 11 from falling out of the second vertical tube 12.
The inner wall surface of the first guide bush 17 is provided with a plurality of first inner ribs 171 extending in the longitudinal direction, and the first inner ribs 171 are movably contacted with the outer wall of the first longitudinal pipe 11 to perform a guiding function and reduce the contact area between the first guide bush 17 and the first longitudinal pipe 11 to reduce the sliding resistance between the first guide bush 17 and the first longitudinal pipe 11.
