Detailed Description

Please refer to fig. 1-3, in the embodiment of the utility model, a height adjustment frame for large-scale display screen, including bolted connection horizontal stand 1 on the wall body, the bolt hole has been seted up on horizontal stand 1, be used for connecting bolt, backplate 8 is installed to the one end of horizontal stand 1, separate display screen and wall body, prevent that display screen and wall body from colliding, montant 2 is installed through welding mode in the bottom of horizontal stand 1, spout 3 has been seted up to montant 2's inside, the cross section of spout is "protruding" font structure, the inner wall sliding connection of spout 3 has slider 4, the cross section of slider is "protruding" font structure, be connected with bearing plate 7 between two sliders 4, form the holding power to the bottom of display screen, the internal thread connection of slider 4 has the screw thread post 5 that runs through to montant 2 top, the top fixedly connected with synchronizing wheel 9 of screw thread post 5, be connected with hold-in range 6 between two synchronizing wheels 9.

The height adjusting frame is matched with a level meter to be installed at a preset height before installation, then a display screen is hoisted by a hoisting machine until the bottom end of the display screen is at the same height with a bearing plate 7 or higher than the height of the bearing plate 7, the hoisting machine drives the display screen to horizontally move until the bottom end of the display screen is in contact with the bearing plate 7 or is positioned right above the bearing plate 7, at the moment, a synchronizing wheel 9 is driven to rotate, the synchronizing wheel 9 drives another synchronizing wheel 9 to synchronously rotate through a synchronizing belt 6, so that two threaded columns 5 are driven to synchronously rotate, at the moment, hua-Yuan-4 moves along the inner wall of a sliding groove 3 under the action of internal threads inside the display screen, contacts with the bottom end of the display screen in the moving process and drives the display screen to move upwards until the bottom end of the display screen moves to the preset position, at the moment, the hoisting machine is matched to completely erect the display screen, and the display screen can be installed at the preset position, and the installation efficiency is improved.

In fig. 1: one end of the back plate 8 is detachably connected with a soft cushion through a bolt, and a bolt connecting point is positioned at the edge of one side of the vertical rod 2; the outer wall cladding of bearing plate 7 has the cushion, and the junction of cushion is located the below of bearing plate 7, and the junction of cushion passes through bolted connection with bearing plate 7.

This kind of cushion, when contacting with the display screen, can prevent the display screen and the wearing and tearing that lead to of device collision itself, can protect the display screen, and after the cushion is used for a long time, its shock-absorbing capacity reduces, the accessible is demolishd the bolt this moment, demolish the cushion of wearing and tearing again, later attach new cushion again, after the cladding is accomplished reuse bolt fastening promptly can, bolt fastening position chooses edge or bottom position, can prevent that the display screen from colliding with bolt point, thereby further avoid hard damage probability, it is half of montant 2 to need to explain that 8 of backplate highly be of backplate, after adjusting predetermined height with the display screen, backplate 8 can not block the connection of the first half of display screen, connect the completion back in the first half, remove the device, can install the latter half of display screen.

In fig. 1: one side of the two vertical rods 2 close to each other is provided with a slot 10, and two ends of the bearing plate 7 are provided with protruding parts which penetrate through the back slot 10 and are connected with the sliding block 4.

This kind of protruding portion has increased the connection area of bearing plate 7 and slider for bearing plate 7 can bear more weight, increases its life, and the protruding portion is when reciprocating along with bearing plate 7, and fluting 10 provides the removal orbit for it, prevents that the protruding portion from removing the in-process obstructed.

In fig. 1 and 3: a plurality of inward-concave tooth sockets are formed on the inner wall of the synchronous belt 6 at equal intervals, a plurality of outward-protruding tooth blocks are formed on the outer wall of the synchronous wheel 9, which is in contact with the synchronous belt 6, and the tooth blocks are meshed with the tooth sockets.

In this kind of synchronous transmission, when a synchronizing wheel 9 rotated, the tooth piece of this synchronizing wheel 9 outer wall was along with rotating, can be through tooth's socket pulling synchronizing wheel 9 transmission to in transmission process through tooth piece and another synchronizing wheel 9 syntropy of tooth's socket pulling, synchronous rotation, the condition that synchronous belt 6 appears skidding in transmission process prevents to appear.

In fig. 1 and 3: the connecting position of the threaded column 5 and the horizontal frame 1 is not provided with threads, the connecting position of the threaded column 5 and the horizontal frame 1 is rotationally connected through a bearing, and the bottom end of the threaded column 5 is rotationally connected with the bottom end of the inner cavity of the vertical rod 2 through a bearing; a driving part is connected above one threaded column 5, and one end of the driving part is fixedly connected to the center of the top end of one synchronizing wheel 9.

This kind of screw post 5 is when rotating, and it can be Z type handle to drive a synchronizing wheel 9 by the drive division and rotate the drive division, also can be the motor, needs to explain to be: if be the motor, need install battery and control switch on the device, control switch comprises switch, controller, and the motor is servo motor, and through the on-off control controller, controller control servo motor carries out just reversing, and the drive division drives a synchronizing wheel 9 when rotating and rotates, and then drives another synchronizing wheel 9 and rotates to drive two screw thread posts 5 and rotate simultaneously, drive slider 4 and reciprocate.

The utility model discloses a theory of operation is: the display screen is lifted by the crane until the bottom end of the display screen is at the same height with the bearing plate 7 or higher than the height of the bearing plate 7, the crane drives the display screen to move horizontally until the bottom end of the display screen is in contact with the bearing plate 7 or is positioned right above the bearing plate 7, the synchronous wheel 9 is driven to rotate at the moment, the synchronous wheel 9 drives the other synchronous wheel 9 to rotate synchronously through the synchronous belt 6, so that the two threaded columns 5 are driven to rotate synchronously, the Chinese love 4 moves along the inner wall of the sliding groove 3 under the effect of internal threads in the Chinese love 4, contacts with the bottom end of the display screen in the moving process and drives the display screen to move upwards until the bottom end of the display screen moves to a preset position, the crane is matched to completely stand the display screen, the display screen can be installed at a preset position, and the installation efficiency is improved.

The above-mentioned, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
