Abstract
The utility model discloses a device for fixing a projector suspension to be suspended on a ceiling. The device comprises a suspender and a suspension connecting piece, wherein the suspender and the suspension connecting piece are connected by a suspender connecting piece, a rotating screw rod inserted into the suspension connecting piece is arranged at the bottom of the suspension connecting piece, an angle fixing bolt penetrating through the suspender connecting piece and used for fixing the rotating screw rod is arranged at the upper part of the rotating screw rod, and a rotating clamp nut is sheathed on the rotating screw rod. According to the device, when angles of the projector need to be adjusted, the projector can be horizontally rotated by 360 degrees, and the existing suspension device has small rotating angles; an inner suspender and an outer suspender of the existing suspension device are made of cylinder metal materials, so the difficulty in punching suspender height adjusting holes is large, while an inner suspender and an outer suspender of the device are made of square pipe metal materials, so the suspender height adjusting holes are easily punched by using a square pipe; the production period is shortened, the production difficulty is lowered, and the manpower cost can be lowered; and the installation is convenient and fast, the installation period is shortened, and the installation difficulty is lowered.
Description
Technical field
The utility model relates to a kind of fixing device, and specifically fixedly projector hanger is lifted into the device of ceiling.
Background technique
The connection set of original passive stereo suspension bracket and top suspension rod is formed by the sheet metal Bending Processing, sheet metal by bent part and top is screwed, the upper metal plate is welded on the suspension rod, the same weld plate in suspension rod top, and the sheet metal punching is connected with ceiling by EXPANSION ANCHOR BOLTS.Original passive stereo lifting top fixing device such as the angle of need adjustment projector substantially horizontal, then needs groove milling realization on circular suspension rod, angle of swing is less, for realizing to adjust up and down, with the form of the little pipe of large pipe inner sleeve, punch at big or small pipe suspension rod, fix with bolt, pipe punching difficulty is large, welds suspension rod and suspension bracket attachment portion panel beating again, and the overall structure flexibility is relatively poor, complex manufacturing, the manufacture cycle is longer.
Summary of the invention
The purpose of this utility model is the deficiency that exists for prior art, provide that a kind of production technology is simple, angular adjustment flexibly fixedly projector hanger be lifted into the device of ceiling.
For realizing above-mentioned model utility purpose, the technical solution adopted in the utility model is the device that a kind of fixedly projector hanger is lifted into ceiling, comprise suspension rod and suspension bracket link, join by hanger rod connecting piece between suspension bracket link and the suspension rod, described suspension bracket link bottom is provided with insertion rotary screw wherein, rotary screw top is provided with to be passed hanger rod connecting piece and is used for the fixedly angle fixing bolt of rotary screw, is socketed with the rotation tightening nut on the rotary screw.
Be the convenient height of adjusting, described suspension rod is adjustable in length formula suspension rod, and suspension rod comprises outer suspension rod and interior suspension rod, and interior suspension rod inserts in the outer suspension rod, has some holes on the suspension rod sidewall outside, is provided with matching used bolt in the hole.
In order to ensure safety, on interior suspension rod sidewall, have equally some holes, bolt passes the hole on outer suspension rod and the interior suspension rod simultaneously, will be highly fixing.
For making things convenient for perforate, described suspension rod is the square tube suspension rod.
A kind of mode of execution, described outer suspension rod is arranged on the top of interior suspension rod, and interior suspension rod lower end is provided with the hanger rod connecting piece fixed hole.
Another kind of mode of execution, described outer suspension rod is arranged on the below of interior suspension rod, and outer suspension rod lower end is provided with the hanger rod connecting piece fixed hole.
Beneficial effect: the utility model projector adjusting angle can horizontally rotate by 360 degree, and the angle of swing of existing hanger device is very little; Suspension rod and outer suspension rod use the cylinder metallic material in the existing hanger device, beat suspension rod height adjustment hole difficulty large, and suspension rod and outer suspension rod use square tube metallic material in this device, it is easily a lot of that square tube is beaten suspension rod height adjustment hole; Manufacture cycle shortens, and reduces production difficulty and reduces human cost; It is convenient to install, and shortens installation period and reduces installation difficulty.
Description of drawings
Fig. 1 is the utility model suspension rod and suspension bracket connection set schematic diagram;
Fig. 2 is a kind of mode of execution schematic diagram of the utility model ceiling fixed derrick.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, the present embodiment is implemented under take technical solutions of the utility model as prerequisite, should understand these embodiments and only be used for explanation the utility model and be not used in restriction scope of the present utility model.
As depicted in figs. 1 and 2, a kind of fixedly projector hanger is lifted into the device of ceiling, comprises suspension rod 1 and suspension bracket link 2, joins by hanger rod connecting piece 3 between suspension bracket link 2 and the suspension rod 1.
Suspension bracket link 2 bottoms are provided with insertion rotary screw 4 wherein, and rotary screw 4 tops are provided with to be passed hanger rod connecting piece 3 and be used for the fixedly angle fixing bolt 5 of rotary screw 4, is socketed with rotation tightening nut 6 on the rotary screw 4.
The utility model uses metallic stamping pieces to make the device that a cover ceiling suspension rod is connected with projector hanger, this application of installation in the projective large-screen display system fixedly projector hanger be connected with the ceiling suspension rod.This device is adjusted by rotary screw and angle tightening nut and is horizontally rotated angle, tightens the angle tightening nut and tightens the angle fixing bolt after adjustment is finished, so that projector is by the angle projection image of expection.
Principle: horizontally rotate angle with being with rotary screw and angle tightening nut to regulate.Suspension rod and outer suspension rod are all used the square tube metallic material in using, and beat the height adjustment hole and regulate support height.Level angle is adjusted rear use angle fixing bolt tilt fixing, hanger rod connecting piece is inserted interior suspension rod, use bolt to be connected by the hanger rod connecting piece fixed hole, inside and outside suspension rod is adjusted by needed height, use bolt to insert suspension rod height adjustment hole level altitude, pass the ceiling fixed block by EXPANSION ANCHOR BOLTS and be fixed on the ceiling.
Former connection set need to mill out conduit at suspension rod in order to realize angular adjustment, and conduit is limited by odjective cause, can not be long, and the fine setting of level angle can only be realized, and 360 degree angular adjustment can be realized after using this device.Former interior suspension rod and outer suspension rod use the cylinder metallic material, beat suspension rod height adjustment hole difficulty large, and suspension rod and outer suspension rod use square tube metallic material in this device, it is easily a lot of that square tube is beaten suspension rod height adjustment hole.
