Abstract
The safe anti-falling projector mount that falls, comprise vertical tube, the upper end of vertical tube is anchored on ceiling board, vertical tube inside arranges internal thread, in vertical tube, coordinate threaded stem is installed, threaded stem and screw-internal thread fit, threaded stem bottom arranges housing, and housing is the channel-section steel that Open Side Down, equipped inside casing in housing, inside casing is stuck in lower to upper, and the middle part of vertical tube arranges two diagonal braces, and cross bar is installed in the end of diagonal brace, cross bar and two diagonal braces form triangular structure, the one end that connects bridle line on inside casing, the other end of bridle line connects pouring weight, and bridle line is wound around cross bar one week.Projector is placed in inside casing, while taking off, directly extract inside casing, once inside casing landing, inside casing tenesmus drives bridle line downward, pouring weight is left behind, according to law of conservation of angular momentum simultaneously, pouring weight can rotate around cross bar under the effect of pulling force, bridle line hangs under the effect of frictional force, thereby inside casing is held, and avoids breaking; Projector lands in time also inside casing protection, avoids projector direct collision, reduces the loss.
Description
Technical field
The utility model relates to projection bracket, specifically a kind of safe anti-falling projector mount that falls.
Background technique
Indoor fixedly projector uses frequent in teaching, work.Projector needs periodic maintenance, while safeguarding, projector is taken off, once grasp shakiness in the process of taking off, can cause projector to fall.Projector placement location is high, must cause projector to damage after falling.
Model utility content
For addressing the above problem, the purpose of this utility model is to provide a kind of safe anti-falling projector mount that falls.
The utility model for achieving the above object, be achieved through the following technical solutions: the safe anti-falling projector mount that falls, comprise vertical tube, the upper end of vertical tube is anchored on ceiling board, vertical tube inside arranges internal thread, in vertical tube, coordinate threaded stem is installed, threaded stem and screw-internal thread fit, threaded stem bottom arranges housing, housing is the channel-section steel that Open Side Down, the bottom of housing arranges the lower edge of inside level, equipped inside casing in housing, inside casing is stuck in lower to upper, housing one end arranges backboard, projector is installed in inside casing, the middle part of vertical tube arranges two diagonal braces, cross bar is installed in the end of diagonal brace, cross bar and two diagonal braces form triangular structure, the one end that connects bridle line on inside casing, the other end of bridle line connects pouring weight, between two diagonal braces, pouring weight seat is set, on pouring weight seat, place pouring weight, bridle line is wound around cross bar one week.
For further realizing the purpose of this utility model, can also be by the following technical solutions: described inside casing both sides arrange slide block, and dovetail groove is offered in housing inwall both sides, dovetail groove and slide block coordinate.Described bridle line is comprised of wire rope core and friction layer, and wire rope core periphery arranges friction layer.
The utility model has the advantage of: of the present utility model projector is placed in inside casing, while taking off, directly extract inside casing, once inside casing landing, inside casing tenesmus drives bridle line downward, pouring weight is left behind, according to law of conservation of angular momentum simultaneously, pouring weight can rotate around cross bar under the effect of pulling force, bridle line hangs under the effect of frictional force, thereby inside casing is held, and avoids projector tenesmus to break; Projector lands in time also inside casing protection, avoids projector direct collision, reduces the loss.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model; Fig. 2 is the left TV structure schematic diagram of Fig. 1; Fig. 3 is the plan structure schematic diagram of Fig. 1; Fig. 4 is the local structure for amplifying schematic diagram of the I of Fig. 1; Fig. 5 analyses and observe structure for amplifying schematic diagram along the A-A line of Fig. 3.
Reference character: 1 pouring weight 2 cross bar 3 vertical tube 4 bridle line 5 threaded stem 6 housing 7 inside casing 8 times is along 9 diagonal brace 10 backboard 11 pouring weight seat 12 dovetail groove 13 slide block 14 projector 15 wire rope core 16 friction layers.
Embodiment
The safe anti-falling projector mount that falls, comprise vertical tube 3, the upper end of vertical tube 3 is anchored on ceiling board, vertical tube 3 inside arrange internal thread, threaded stem 5 is installed in the interior cooperation of vertical tube 3, threaded stem 5 and screw-internal thread fit, by adjusting the length of thread engagement of threaded stem 15 and vertical tube 3, thereby realize height and the projection angle that regulates projector 14.Threaded stem 5 bottoms arrange housing 6, housing 6 is the channel-section steel that Open Side Down, the bottom of housing 6 arranges the lower to 8 of inside level, the interior equipped inside casing 7 of housing 6, inside casing 7 is stuck in lower on 8, and housing 6 one end arrange backboard 10, the interior installation projector 14 of inside casing 7, inside casing 7 coordinates with housing 6 pulls, conveniently picks and places projector.The middle part of vertical tube 3 arranges two diagonal braces 9, cross bar 2 is installed in the end of diagonal brace 9, cross bar 2 and two diagonal braces 9 form triangular structure, the one end that connects bridle line 4 on inside casing 7, the other end of bridle line 4 connects pouring weight 1, between two diagonal braces 9, pouring weight seat 11 is set, places pouring weight 1 on pouring weight seat 11, bridle line 4 is wound around cross bar 2 one weeks.Of the present utility model projector is placed in inside casing, while taking off, directly extract inside casing, once inside casing landing, inside casing tenesmus drives bridle line downward, pouring weight is left behind, according to law of conservation of angular momentum simultaneously, pouring weight can rotate around cross bar under the effect of pulling force, bridle line hangs under the effect of frictional force, thereby inside casing is held, and avoids breaking projector; Projector lands in time also inside casing protection, avoids projector direct collision, reduces the loss.Described inside casing 7 both sides arrange slide block 13, dovetail groove 12 is offered in housing 6 inwall both sides, and dovetail groove 12 and slide block 13 coordinate, and inside casing 7 can coordinate by pull with housing 6, while dovetail groove 12 coordinates to the support of one of inside casing both sides with slide block 13, improves the steadiness after inside casing 7 is installed.Described bridle line 4 is comprised of wire rope core 15 and friction layer 16, and wire rope core 15 peripheries arrange friction layer 16, and friction layer 16 effectively increases frictional force, and bridle line 4 is effectively coordinated with cross bar 2, reaches the object of safe anti-falling.
Certainly, above-mentioned explanation is not to restriction of the present utility model, and the utility model is also not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, change, interpolation or replacement, all should belong to protection domain of the present utility model.
