Description
Technical field
The present invention relates to a kind of stationary installation, it is a kind of Novel projector stationary installation specifically.
Background technology
A kind of stationary installation that projector stationary installation is carrying projector and is fixed on ceiling, is mainly used in classroom, academic hall and bigger meeting-place, and this device can reasonably utilize space, convenient teaching and work.
At present, needs according to work, also there are some defects in traditional stationary installation, as: existing projector must coordinate people's word ladder etc. to dismount, particularly during maintenance, it is necessary to bigger labor force, for higher meeting-place, realize more difficult, and bring bigger potential safety hazard to work.
In order to overcome above-mentioned defect, on the basis of existing technology, make a formal request the ratchet rotating shaft lifting structure of people in conjunction with home-use clothes hanger, the basis of original anchor has been done corresponding improvement, propose a kind of new technical scheme, it provides a kind of novel projector stationary installation that can automatically dismount.
Summary of the invention
The object of the present invention provides a kind of Novel projector stationary installation.
For achieving the above object, the technical scheme of the present invention, comprise fixing top board and box body, described fixing top board is provided with the fixed orifices projected upwards, the lower end of this fixing top board is fixedly connected with permanent joint, the upper end of described box body is fixedly connected with lifting joint, and described fixing top board is provided with the string holes that two run through this fixing top board, is respectively equipped with top board pulley in the side, upper end of string holes.
The lower end of described permanent joint inside is cone, inner upper end is cylinder shape and is connected with string holes, the sidewall of this permanent joint is fixedly connected with latching system, this latching system comprises curved bar, spring, the fixed link being connected respectively by bearing pin and cross bar with curved bar, one end of described spring is connected with the upper end of curved bar, the other end of spring is connected with the sidewall of permanent joint, and described cross bar runs through the sidewall of this permanent joint.
The upper end of described lifting joint is provided with the projection matched with permanent joint, and the sidewall in projection is provided with the card groove matched with cross bar.
This Novel projector stationary installation also comprises two middle runners and control enclosure, two ratchet rotating shafts it are provided with in described control enclosure, one end of described two ratchet rotating shafts is respectively equipped with a rotation handle, and these two ratchet rotating shafts are connected with curved bar and projection respectively by wireline.
Owing to adopting technique scheme, the useful effect of the present invention is: this device replaces artificial dismounting, automatically dismounts, greatly facilitate maintenance and the maintenance of equipment under the cooperation not needing people's word ladder;Avoid climbing people's word ladder, ensure the safety of work.
Accompanying drawing explanation
Now the present invention will be further described by reference to the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation that permanent joint and lifting joint coordinate latching system
In figure: 1, fixing top board, 11, fixed orifices, 12, string holes, 13, top board pulley, 2, box body, 3, permanent joint, 4, lifting joint, 41, protruding, 42, card groove, 5, latching system, 51, curved bar, 52, spring, 53, fixed link, 54, cross bar, 6, middle runner, 7, control enclosure, 71, ratchet rotating shaft, 72, rotate handle, 8, wireline.
Embodiment
As shown in Figure 1, 2, the present invention comprises fixing top board 1 and box body 2, described fixing top board 1 is provided with the fixed orifices 11 projected upwards, the lower end of this fixing top board 1 is fixedly connected with permanent joint 3, the upper end of described box body 2 is fixedly connected with lifting joint 4, described fixing top board 1 is provided with the string holes 12 that two run through this fixing top board 1, is respectively equipped with top board pulley 13 in the side, upper end of string holes 12.
The lower end of described permanent joint 3 inside is cone, inner upper end is cylinder shape and is connected with string holes 12, the sidewall of this permanent joint 3 is fixedly connected with latching system 5, this latching system 5 comprises curved bar 51, spring 52, the fixed link 53 being connected respectively by bearing pin and cross bar 54 with curved bar 51, one end of described spring 52 is connected with the upper end of curved bar 51, the other end of spring 52 is connected with the sidewall of permanent joint 3, and described cross bar 54 runs through the sidewall of this permanent joint 3.
The upper end of described lifting joint 4 is provided with the projection 41 matched with permanent joint 3, and the sidewall protruding 41 is provided with the card groove 42 matched with cross bar 54.
This Novel projector stationary installation also comprises two middle runners 6 and control enclosure 7, two ratchet rotating shafts 71 it are provided with in described control enclosure 7, one end of described two ratchet rotating shafts 71 is respectively equipped with a rotation handle 72, and these two ratchet rotating shafts 71 are connected with curved bar 51 and protruding 41 respectively by wireline 8.
Principle of work: before not installing, the upper end of curved bar 51 strained by spring 52, cross bar 54 is not through the sidewall of permanent joint 3, by rotating ratchet rotating shaft 71, lifting joint 4 rises, when lifting joint 4 and permanent joint 3 coincide, rotating another ratchet rotating shaft 71, curved bar 51 makes cross bar 54 through the sidewall of permanent joint 3 and reach in card groove 42 and be fixed by lifting joint 4 under the traction of wireline 8; When repair demolition formula, only the ratchet rotating shaft 71 of control curved bar 51 need to being reversed, can be retracted by cross bar 54 under the contraction of spring 52, then reversing another ratchet rotating shaft 71 realizes the decline of box body 2.
