Connected to the pawl 552 is an angularly disposed stem 553, the height of the stem 553 being adjustable to allow abutment with a lowermost notch of the ratchet bar 543. A cross rod 554 is connected to the bottom end of the vertical rod 553, a lug 551 is arranged at the bottom of the intersection position of the cross rod 554 and the vertical rod 553, and the lower end of the lug 551 is hinged on a connecting seat 581 arranged on the top surface of the bottom plate 58. One end of a compression spring 57 is connected to the bottom of the free end of the cross rod 554, and the other end of the compression spring 57 is connected to the bottom plate 58. That is, the pawl 55 forms a lever, and the lug 551 is used as the fulcrum of the lever, and the pawl 552 can be moved out of the ratchet bar 543 by pressing the cross rod 554, and can be reset by the compression spring 57 after being moved out.
Alternatively, the spring 57 is mounted at both ends in spring seats fixed to the top surface of the base plate 58 and the bottom surface of the cross-bar 554, respectively.
Referring to fig. 1-3, optionally, one end of the pedal 56 is hinged to the side of the cross-bar 554, and the other end of the pedal 56 hangs on the ground. When the rotation gear 59 moves the lifting column 54 downward, the pawl 552 moves out of the notch of the ratchet bar 543 by pressing the pedal 56 with a foot, thereby achieving the falling of the lifting column 54, i.e., the lowering of the height of the display screen 1.
Optionally, a non-slip protrusion is provided on the surface of the pedal 56 that contacts the foot.
Optionally, a top rod 541 is disposed on the top of the lifting column 54, and the top of the top rod 541 passes through the receptacle 3 and is disposed in a positioning sleeve in the inner cavity of the base 2. The purpose of the lift pins 541 is to extend the height of the lifting columns 54 so that the base plate 58 is as close to the ground as possible.
Referring to fig. 5, in one possible implementation, a flange 513 is provided at the top of the sleeve 51, and the lifting mechanism 5 is secured to the mounting surface by the flange 513. A long groove 512 through which the pawl 55 passes is provided in a lower portion of the sleeve 51, and when the lifting column 54 moves up and down, the pawl 55 passes through the long groove 512 and abuts against the ratchet 543.
Referring to fig. 4 and 5, optionally, a locking groove 544 is provided on the lifting column 54, and correspondingly, a boss 511 for cooperating with the locking groove 544 is provided on the inner wall of the sleeve 51.
For example, referring to fig. 6, when the present embodiment is specifically installed, the display screen 1 is firstly placed on the desktop of the desk 6 together with the base 2 and the receptacle 3, and the receptacle 3 is fixed on the desktop. The mounted lifting mechanism 5 is then mounted to the bottom of the table via flange 513 so that the pedals 56 and handle 53 face one side of the person's seat, completing the installation. When the display screen 1 needs to be raised, the operator sits on the seat and can rotate the handle 53, the pawl 55 automatically clamps the lifting column 54 through the mandril of the lifting column 54 jacking the base 2 in the process of moving the lifting column 54 upwards, and the lifting column 54 is prevented from moving downwards. When the height of the display screen 1 needs to be lowered, the pedal 56 is stepped on by feet, so that the pawl 55 moves out of the lifting column 54, the handle 53 is slowly rotated, so that the lifting column 54 slowly falls, and when the proper position is reached, the pedal 56 is released, so that the lifting column 54 is automatically locked. The whole process can be finished by an operator sitting on the seat, and the use is convenient.
