Description

Lifting screen frame

Technical field

The present invention relates to a kind of lifting screen frame more particularly to a kind of liftings that adjustable height is improved by push lifting device Screen frame.

Background technique

As the science and technology of modern society is more and more flourishing, the size of liquid crystal display is also increasing, previous to need to pass through Projector and projection screen can just carry out bulletin meeting, liquid crystal display broadcasting can be used now, and liquid crystal display is liquid crystal Touch Screen, it is existing that liquid crystal display can set up to the equipment of getting up, general such as wall hanging frame, the metal frame for manually adjusting formula, with Liquid crystal display all can be set up by the electric elevating rack of power ramp, if liquid crystal display is fixedly arranged on wall hanging frame, Liquid crystal display can not be moved arbitrarily, lead to the problem of that mobility is bad, if to manually adjust the metal frame of formula installing liquid crystal Showing device, the height that adjust liquid crystal display is not convenient operation, and expensive with the amount of money of the electric elevating rack of power ramp, And lifting speed is slow, above-mentioned wall hanging frame, metal frame or electric elevating rack all have the problem of its not convenient or bad practicality.

To solve the problems, such as above-mentioned bad practicality, with the crane of a setting lifting pneumatic cylinder, pass through the lifting air pressure Cylinder raises the height of the crane, and liquid crystal display can be located at apart from higher position, the wall hanging frame can be overcome any Mobile problem, and the lifting pneumatic cylinder lifting air cylinder pressure can allow liquid crystal display that can adjust movement up and down, promote mobility, And overcome metal frame adjustment complicated, allow lifting valence promotion convenience easy to adjust, and opposite electric elevating rack the amount of money more Cost is saved, practicability is improved.

However, the screen with liquid crystal display is increasing, for the liquid crystal display of existing screen sizes, If to go up and down the crane of pneumatic cylinder lifting, the height that the crane can be lifted is raised to apart from the position on 100 centimeters of ground, can not The liquid crystal display of screen sizes is allowed to install and use, the problem for causing the applicability of existing crane bad, and if In order to allow the elevated height of the lifting frame, the wider lifting pneumatic cylinder of one range of production, then make the range compared with The technology of wide lifting pneumatic cylinder and the structure of gas accommodating, the increased costs that can all make manufacture spend, if using the lifting It will cause the cost increases of the crane for the wider lifting pneumatic cylinder of range.

Summary of the invention

The main purpose of the present invention is to provide a kind of lifting screen framves, if by improve using existing lifting pneumatic cylinder as The lifting apparatus of crane, the then limited height being lifted cause the problem that applicability is bad.

To achieve the aforementioned purpose, lifting screen frame of the present invention includes:

One pedestal；

One push lifting device, the push lifting device are set to the pedestal, which includes a hollow guiding tube, a promotion Pipe, a hollow carrying pipe, a pedal base, a pedal, one raise bar and one lifting pneumatic cylinder, the guiding tube be set to the pedestal, The riser is movably disposed in the guiding tube and moves up and down on the outside of the guiding tube, which is set to the top of the pedestal Portion and the inside for being located at the guiding tube, the pedal base are set to the bottom of the pedestal, which is hubbed at the pedal base, the pedal packet Containing an initiative part and an operand, which is located at one end of the pedal and is located at the outside of the pedestal, which is located at The other end of the pedal and be located at the carrying pipe lower section, this raise bar set on the carrying pipe inside and pass through the pedestal against On the pedal, which is set to the inside of the riser and protrudes into the guiding tube, which includes a gas Pressure bar, a trigger valve and a lifting pipe, the air pressure rod are fixedly arranged on the top of the carrying pipe, which is set to the bottom of the air pressure rod Portion, the lifting pipe are movably disposed on the air pressure rod, the inner top of the fixed riser in the top of the lifting pipe；And

One assembling apparatus, the assembling apparatus are set to the riser and are located at the top of the riser.

Lifting screen frame of the present invention raises bar by this, increases the initial position of the riser, allows the initial of the riser The initial position of the relatively existing crane in position is higher, then the assembling apparatus rises the position reached and increases upwards, group tipping It sets that the distance between the pedestal is longer, is more suitable for the liquid crystal display of screen sizes, everybody can be allowed to be clearly seen the liquid The overall picture of crystal display allows applicability of the invention to be promoted.
