Description of drawings
Fig. 1 is the perspective view of detector array type electronic white boards projection described in the utility model location lowering or hoisting gear;
Among the figure: 1, base, 2, fixing frame, 3, guide rail sleeve, 4, movable frame, 5, linear electric motor, 6, output shaft, 7, bottom bracket, 8, bracket, 9, the bracket motion bar, 10, expansion bracket, 11, flexible rod, 12, the expansion bracket cover, 13, the expansion bracket screw, 14, expansion bracket cover screw.
Embodiment
Below by specific embodiment the utility model detector array type electronic white boards projection location lowering or hoisting gear is described in further detail.
As shown in Figure 1, detector array type electronic white boards projection location lowering or hoisting gear, comprise base 1, be fixed with fixing frame 2 on the base 1, be fixed with four guide rail sleeves 3 on the fixing frame 2, be respectively arranged with the very little slide block of friction factor in the guide rail sleeve 3, movable frame 4 penetrates and is arranged in the guide rail sleeve 3, be fixed with linear electric motor 5 on the fixing frame 2, the output shaft 6 of linear electric motor 5 is connected with movable frame 4, thereby movable frame 4 can vertically be moved up and down on the edge in guide rail sleeve 3, movable frame 4 is provided with detector array type electronic white boards fixing device and projector fixing device, described detector array type electronic white boards fixing device comprises two bottom brackets 7 that are fixed on movable frame 4 lower ends and two bracket 8 that are movably arranged on movable frame 4 upper ends, described two bracket 8 fix with bracket motion bar 9 respectively, described bracket motion bar 9 penetrates respectively and is arranged in the movable frame 4, thereby two bracket 8 can vertically be moved up and down on the edge in movable frame 4.Described projector fixing device comprises the expansion bracket 10 that is movably arranged on movable frame 4 tops, laterally be movably set with flexible rod 11 in the expansion bracket 10, expansion bracket 10 is provided with expansion bracket screw 13, described expansion bracket screw 13 is movably arranged in the expansion bracket 10 by screw thread, tightening expansion bracket screw 13 can make flexible rod 11 be fixed in the expansion bracket 10, expansion bracket 10 activities penetrate and are arranged in the expansion bracket cover 12, expansion bracket cover 12 is provided with expansion bracket cover screw 14, described expansion bracket cover screw 14 is movably arranged on the expansion bracket cover 12 by screw thread, described expansion bracket cover 12 fixes with movable frame 4, thereby expansion bracket 10 can be tightened expansion bracket cover screw 14 expansion bracket 10 is fixed in the expansion bracket cover 12 along vertically moving up and down in movable frame 4.
Working principle of the present utility model is: during use, above-mentioned base 1 is placed on the ground, also can not used base 1, fixing frame 2 is directly hung on the wall.Detector array type electronic white boards is fixed on the movable frame 4 by bracket 8 and bottom bracket 7, owing to be to flexibly connect between two bracket 8 and the movable frame, so upper-lower position that can be by regulating bracket 8 is to adapt to the detector array type electronic white boardss of different sizes; Projector is fixed on the flexible rod 11, because between expansion bracket 10 and the expansion bracket cover 12 is to flexibly connect, so can regulate the upper-lower position of projector by regulating the upper-lower position of expansion bracket 10 in expansion bracket cover 12, owing to be to flexibly connect between expansion bracket 10 and the flexible rod 11, can regulate the front and back position of projector by regulating the front and back position of flexible rod 11 in expansion bracket 10.After adjust the above-mentioned detector array type electronic white boards and the mounting point of projector, between projector and detector array type electronic white boards, carry out adjustment and with the fixed-site of detector array type electronic white boards and projector.When the user of different heights uses, the stretching out or withdraw of output shaft 6 that can be by linear electric motor 5, movable frame 4 is moved up or down in guide rail sleeve 3, because detector array type electronic white boards is to be fixed in the movable frame 4, thus the upper-lower position adjusting of realization detector array type electronic white boards, again because projector also is to be fixed in the movable frame 4, so movable frame 3 is when moving up and down, relative position between detector array type electronic white boards and the projector remains unchanged, thus need not adjustment again again, easy to use.
