Abstract
The utility model provides a distance-adjustable laser display device which mainly relates to a laser lamp, in particular to a laser lamp which is arranged on recreational instruments, such as a dartboard, and the like and can regulate the irradiation distance. The distance-adjustable laser display device which comprises the laser lamp (1) is characterized in that the laser lamp (1) is arranged on a rotating shaft (2), two ends of the rotating shaft (2) are fixed on shaft seats (3,4), and an adjusting wheel (4) is also fixed on the rotating shaft (2). By adopting the structure, the angle of the laser lamp can be adjusted by rotating the adjusting wheel on the dartboard, thereby adjusting the distance that rays irradiated from the laser lamp are projected on the dartboard on the ground and achieving the aim of adjusting the change of display distances.
Description
Technical field
But a kind of roll adjustment of the utility model, radium-shine display unit relate generally to a kind of radium-shine lamp, especially relate to a kind of radium-shine lamp that can regulate irradiation distance on the play apparatus such as boomerang plate that is installed in.
Background technology
Boomerang plate is as a kind of amusement, sports utensil, and people are not strange to him.People will stand in outside the certain distance of boomerang plate and throw boomerang in use, and in multiplayer or when sports, normally at standardized line with a certain distance from boomerang plate outside, all throwing boomerang persons are with this line throwing boomerang that exceeds.Owing to be subjected to the restriction in place, also need to carry simultaneously instruments such as chalk, ruler, line is inconvenient sometimes.Sometimes there are many groups personnel to play or race, just need to draw many lines, very trouble.
Summary of the invention
But the purpose of this utility model provides a kind of roll adjustment, radium-shine display unit, and it has overcome the above defective, is installed on the boomerang plate, and is simple in structure, easy and simple to handle, can regulate range of a signal arbitrarily, made things convenient for player or competitor.
But the technical solution of the utility model is a kind of roll adjustment, radium-shine display unit, comprises radium-shine lamp 1, it is characterized in that described radium-shine lamp 1 is loaded on the turning cylinder 2, and the two ends of turning cylinder 2 are fixed on the axle bed 3,6, also are fixed with regulating wheel 4 on turning cylinder 2.
But above-mentioned a kind of roll adjustment, radium-shine display unit, described axle bed 3 comprise loam cake 31 and following 32, are with O shape rubber ring 5 on the end of turning cylinder 2 and position that axle bed 3 cooperates.
Above-mentioned a kind of cocoa roll adjustment, radium-shine display unit have an annular groove in described axle bed 3 or axle bed 6 axle sleeves, and there is a flange 2 corresponding positions of turning cylinder.
But above-mentioned a kind of roll adjustment, radium-shine display unit have a groove 33 on described loam cake 31 and following 's 32 the inner surface, and there is flange 21 the left part institute corresponding position of turning cylinder 2.
But above-mentioned a kind of roll adjustment, radium-shine display unit, the centre bore 41 of described regulating wheel 4 is cubic hole, and cubic step 22 is arranged on the turning cylinder 2.
But above-mentioned a kind of roll adjustment, radium-shine display unit is characterized in that having a sleeve 5 to be fixed on the turning cylinder 2 or integrally formed with turning cylinder 2, and radium-shine lamp 1 is loaded in the sleeve 5.
Adopt above-mentioned structure, on boomerang plate, rotate regulating wheel, will adjust the angle of radium-shine lamp, thus adjust the emitted light of radium-shine lamp in the projection on ground in the distance of boomerang plate, reach the variation of adjusting its range of a signal.
Description of drawings
But the schematic appearance of Fig. 1 a kind of roll adjustment that is the utility model, radium-shine display unit embodiment.
But the inside installation diagram of Fig. 2 a kind of roll adjustment that is the utility model, radium-shine display unit embodiment.
Fig. 3 is a component drawings shown in Figure 2.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
See Fig. 1, Fig. 2, shown in Figure 3:
But the technical solution of the utility model is a kind of roll adjustment, radium-shine display unit, Fig. 1, Fig. 2, shown in Figure 3 be one embodiment.Comprise radium-shine lamp 1, it can shine projection and go out a line segment, and this described radium-shine lamp 1 is loaded on the turning cylinder 2, for fixing radium-shine lamp 1 better, can make a sleeve 5, described sleeve 5 is fixed on the turning cylinder 2 or is integrally formed with turning cylinder 2, and radium-shine lamp 1 is loaded in the sleeve 5.The two ends of described turning cylinder 2 are fixed on the axle bed 3,6, further mode, described axle bed 3 comprises loam cake 31 and following 32, on the end of turning cylinder 2 and position that axle bed 3 cooperates, be with O shape rubber ring 5, on turning cylinder 2, also be fixed with regulating wheel 4, the centre bore 41 of described regulating wheel 4 is cubic hole, and cubic step 22 is arranged on the turning cylinder 2, so rotates regulating wheel 4 and will drive turning cylinder 2 rotations.Player or player can be as required adjust the angle of radium-shine light irradiation by rotating regulating wheel 4, thereby adjust line segment that its irradiation projection goes out to determine distance.For preventing that turning cylinder 2 from freely rotating, especially when throwing boomerang, the vibrations of boomerang dish can utilize the resistance that elasticity produced of rubber ring 5 to prevent turning cylinder 2 minor rotation effectively by O shape rubber ring 5 is installed through the minor rotation that regular meeting causes turning cylinder 3.
Further mode has a groove 33 on described loam cake 31 and following 's 32 the inner surface, and there is flange 21 the left part institute corresponding position of turning cylinder 2.So, can prevent the axial displacement of the turning cylinder 2 that the vibrations because of boomerang plate cause.
See shown in Figure 1ly, press power switch, radium-shine lamp energising promotes regulating wheel by the diagram indication and will drive moving runner and rotate, thereby changes the angle on radium-shine lamp wiring and ground, and angle is big more, and distance is short more, and angle is more little, apart from long more.
