Abstract
The utility model relates to a gravity center adjusting device for a hoisted light emitting diode (LED) display screen, belonging to the technical field of LED display screens and particularly the technical field of gravity center adjustment of the hoisted LED display screen, aiming at solving the technical problem that the display effect of the entire LED display screen is affected because the gravity center of the box body of the hoisted LED display screen tilts rearwards and the LED display screen is in an inclined state. The gravity center adjusting device comprises a fixing seat. A vertical through hole is arranged on the fixing seat. An adjusting screw is in threaded connection with the vertical through hole. The gravity center adjusting device is installed on the internal lower frame of the box body of the hoisted LED display screen, after the device is ejected out of the box body through the adjusting screw, the device is ejected against the upper frame of a box body which is hoisted below the device, the lower frame of one box body and the upper frame of the other box body are enabled to be in a parallel state, therefore the situation that the lower part of the box body tilts rearwards with the gravity center can be avoided, the hoisted LED display screen is enabled to be installed in an upright state and the visual effect is ensured to be good.
Description
Technical field
The utility model relates to the LED display technical field, is specifically related to be used for to LED lifting display screen center of gravity regulation technology field.
Background technology
Because present LED display is no matter be hard-wired, still the lease formula lifts, the casing of display screen all is towards doing thinner and thinner, the direction of doing lighter and lighter develops, because the casing of display screen is done the leading flank of thin and casing and is provided with some lamp bars and control circuit, the weight of leading flank is obviously greater than trailing flank weight, the casing center of gravity is to retrodeviating, because a LED screen is hung to connect by the davit between casing by some casings and forms, on, be certain to exist certain clearance between following two casings, be lifted on the LED display of forming together at a plurality of casings and whole center of gravity will occur to retrodeviating, also be that LED display is inclined, can influence the display effect of whole LED display screen.
Summary of the invention
The purpose of this utility model is to solve the casing center of gravity of above-mentioned LED lifting display screen to retrodeviating, cause LED display inclined, can influence the technical problem of the display effect of whole LED display screen, and propose the center of gravity adjusting device that a kind of LED lifting display screen is used.
For solving the technical problem that the utility model proposed, the scheme that adopts is: the center of gravity adjusting device that a kind of LED lifting display screen is used, it is characterized in that: include a holder, described holder is provided with vertical through hole, in the described vertical through hole by the adjusting screw(rod) that has been threaded.
As the further improved technical scheme of the utility model is included:
Also be provided with an adjusting pillar that passed by the adjusting screw(rod) bottom in the vertical through hole on the described holder.
Be socketed with compression spring on the described adjusting pillar, the top of described adjusting pillar is provided with the compression spring top and cooperates the raised step that stops.
Described adjusting screw(rod) top is provided with the manual adjustments handle.
Also be provided with a horizontally disposed latch on the described holder.
The beneficial effects of the utility model are: the utility model is installed on the lower frame in the casing of LED lifting display screen, after ejecting in the casing by adjusting screw(rod), withstand on the upper side frame of the casing that lifts below it, make a wherein lower frame of two tanks become parastate with another casing upper side frame, avoided lower box with center of gravity to retrodeviating, thereby make LED lifting display screen become vertical state to install, guarantee good visual effect.

Embodiment
Below in conjunction with accompanying drawing and preferred specific embodiment structure of the present utility model is further described:
Shown in Fig. 1, Fig. 2 and Fig. 3, the utility model includes a holder 2, is provided with the vertical through hole 21 that is connected to the bottom surface from the end face of holder 2 on holder 2, in vertical through hole 21 by the adjusting screw(rod) 3 that has been threaded.Adjusting screw(rod) 3 advances when turning clockwise straight down, when being rotated counterclockwise, withdraws from straight up.Manual adjustment adjusting screw(rod) 3 is provided with manual adjustments handle 31 on adjusting screw(rod) 3 tops for convenience.Also be provided with an adjusting pillar 4 that passed by adjusting screw(rod) 3 bottoms in the vertical through hole 21 on holder 2.Be socketed with compression spring 5 on adjusting pillar 4, the top of described adjusting pillar 4 is provided with compression spring 5 tops and cooperates the raised step 41 that stops.
Shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the utility model when mounted, it is installed on the lower frame 11 in the casing 1 of LED lifting display screen, holder 2 can be an independently holder, it also can be the locking bolt seat in the shared existing casing 1, so-called locking bolt seat that is to say that one is used for after the davit 12 of lower square box inserts in it, and with the holder of davit 12 lockings, this locking bolt seat is provided with the horizontally disposed latch 22 that is used to insert in davit 12 connecting holes.Be provided with one on the lower frame 11 in casing 1 only for regulating the through hole that pillar 4 is vacated, when turning clockwise adjusting screw(rod) 3, regulate pillar 4 and eject casing 1, when being rotated counterclockwise, regulating pillar 4 and be stressed and reset under spring 5 effects from casing 1 lower frame 11.
Shown in Fig. 5, upper and lower two casings 1,1 ' are to rely on davit and hang connection, must have certain clearance between two casings 1,1 ', the amount of stressing imbalance before and after the casing 1 ' in addition, and casing 1 ' must recede.
With reference to Fig. 6, and in conjunction with shown in Fig. 2, by the adjusting screw(rod) 3 in the casing 1 of clockwise direction rotation top, to regulate pillar 4 ejects downwards, regulate the end face that pillar 4 bottoms withstand on lower square box 1 ', adjust the gap between two tanks 1,1 ', make casing 1 upper bottom surface of top and the end face of lower square box 1 ' be in parastate.Be laborsaving and box deformation, adjusting screw(rod) 3 positions are as far as possible by the casing trailing flank, shown in Fig. 3.
