Technical field

The present invention relates to film instruments, more particularly to a kind of film frame.

Background technique

Community, method used in rural area open air broadcasting film are that screen is directly hung to tree is upper or fixed at present Hanging beam, also having packaged type equipment is for example mobile broadcasting trolley.Hanging the problems of screen is required to place, The larger installation of screen is inconvenient, and high altitude operation is more dangerous；Mobile broadcasting trolley is inconvenient to carry and transports, because simultaneously by body Product limitation can only use small-sized screen.

Summary of the invention

In order to overcome the deficiencies in the prior art, the present invention provides a kind of film framves.

The present invention is achieved by the following technical solutions: a kind of film frame, including strut, pulley, screen, traction rope, Pedestal, pulley base and square tube, it is characterised in that: the pedestal is vertically arranged strut in cross on pedestal center position, described Fixed ring is set in strut bottom side of the wall, pulley base is provided on the side wall of strut upper end, the pulley is fixed on by pulley base On strut；Screen is unfolded for horizontally disposed upper keel and lower keel, upper keel and lower keel above and below the screen, institute It states upper keel both ends setting screen lifting rope upper keel both ends are connected, described traction rope one end is fixed on screen lifting rope, another End is downwardly fixed in fixed ring after bypassing from the top of pulley.

In above scheme, the pedestal, strut are made of multiple square tubes, and described square tube one end is opening, other end Protruding pin compatible with inner hole of square is set.

In above scheme, it is provided with reinforcement fixed ring on the pedestal, the both ends of the upper keel and lower keel are respectively provided with There is fixed rope to be connected to reinforce in fixed ring.

A kind of film frame of the present invention compared with prior art, the beneficial effect is that:

1, the film frame carries strut, and installation is not necessarily to fixed venue on the spot, and operation is facilitated to improve working efficiency；

2, strut height may be selected in the film bracket, adapts to a variety of size screens；

3, component is the body of rod, lifting rope, and each connecting component using guide connects connection type between bracket, occupies after storage It occupies a narrow space, is flowed convenient for suburb.

Detailed description of the invention

In figure: 1. brackets, 2. pulleys, 3. screen lifting ropes, 4. upper keels, 5. screens, 6. fixed ropes, 7. lower keels, 8. is solid Determine ring, 9. traction ropes, 10. pedestals, 11. protruding pins, 12. is open, and 13 reinforce fixed ring, 14. pulley bases, 15. square tubes.

Specific embodiment

Be further described with reference to the accompanying drawing with specific embodiment to film frame of the present invention: Fig. 1 is of the invention a kind of The structural schematic diagram of film frame；Fig. 2 is the right side structure schematic diagram of film frame.In figure, the film frame, including strut 1, pulley 2, Screen 5, traction rope 9, pedestal 10, pulley base 14 and square tube 15, pedestal 10 are vertically arranged in cross on 10 center position of pedestal Fixed ring 8 is arranged in 1 bottom side of the wall of strut, is provided with pulley base 14 on 1 upper end side wall of strut, pulley 2 passes through pulley for strut 1 Seat 14 is fixed on strut 1；Horizontally disposed upper keel 4 and lower keel 7, upper keel 4 and lower keel 7 above and below screen 5 Screen 5 is unfolded, 4 both ends of upper keel are connected by 4 both ends of upper keel setting screen lifting rope 3, and 9 one end of traction rope is fixed on screen and hangs On rope 3, the other end is downwardly fixed in fixed ring 8 after bypassing from the top of pulley 2.Pedestal 10, strut 1 are by multiple square tubes 15 It constitutes, 15 one end of square tube is opening 12, and protruding pin 11 compatible with 15 inner hole of square tube is arranged in other end.It is provided on pedestal 10 The both ends of reinforcement fixed ring 13, upper keel 4 and lower keel 7, which are provided with fixed rope 6 and are connected to, to be reinforced in fixed ring 13.

The film frame is in use, first assemble pedestal 10 and bracket 1, successively 12 connection of protruding pin 11 and opening in square tube 15 After the completion, 9 one end of traction rope is passed through into pulley 2 and screen lifting rope 3 is fixed, pull other end traction rope 9, screen lifting rope 3 at this time Dragging upper keel 4 move up screen 5, while lower keel 7 it is sagging make screen 5 be unfolded, until screen 5 is increased to appropriate height When traction rope 9 is fixed on fixed ring 8, also can bypass the reinforcement fixed ring that traction rope 9 is fixed on pedestal 10 by fixed ring 8 13.Finally the fixed rope 6 at 7 both ends of upper keel 4 and lower keel is fixed on pedestal 10 reinforce fixed ring 13 accordingly can be complete At installation.

The film frame can suitably increase bracket connection quantity according to screen size, and then solve the screen height of different wide cuts Limited problem.Each connecting component connects connection type using guide simultaneously, and install convenient effectively mitigates labor burden.All components Be the body of rod, lifting rope storage after take up little area, be more suitable for suburb flowing, improve working efficiency.

The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, though So the present invention has been disclosed as a preferred embodiment, and however, it is not intended to limit the invention, any technology people for being familiar with this profession Member, without departing from the scope of the present invention, when the method and technique content using the disclosure above make it is a little more Equivalent embodiment that is dynamic or being modified to equivalent variations, but anything that does not depart from the technical scheme of the invention content, according to the present invention Technical spirit any simple modification, equivalent change and modification to the above embodiments, still fall within technical solution of the present invention In range.
