Abstract
The utility model relates to a height adjustable projection device. The device comprises a base, a first connecting rod, a second connecting rod, a projector, wheels and a dead lever. The device is characterized in that the upper part of the base is connected to the hollow first connecting rod, and the lower part of the projector is connected with the hollow second connecting rod. The perimeter of the second connecting rod is less than the perimeter of the first connecting rod, so that the second connecting rod can be inserted into the first connecting rod. Two circular holes are symmetrically disposed at the diameter of the upper periphery of the first connecting rod. Circular hole groups are uniformly disposed on the second connecting rod at an interval of 5 cm. the circular holes on the first connecting rod are equal to the circular holes on the second connecting rod. The dead lever can simultaneously pass through the circular holes on the first and the second connecting rods, so that when the height of the projector is set, the dead lever can fix the projector. The wheels are disposed at the four corners of the bottom part of the base, so that the projection device can move by sliding the wheels. The projection device is simple in structure and easy to manufacture.
Description
Technical field
The utility model relates to a kind of projection arrangement, the projection arrangement that more precisely a kind of height can regulate.
Background technology
Projector is a very important part in present people's daily life, people can use projector that the document on computer or glass plate is projected to above screen, teacher can save by use projector the work that much need to state at blackboard upper plate in the process of giving lessons, in the time of company's the inside meeting or allocating task, by use projector, also can simplify a lot of linguistic elaborations, in a word, projector has all obtained application very widely aspect people's working and learning a lot, people's projector used in everyday often fixed placement in a certain position, if need the vicissitudinous words of the height of projection also to need constantly to change the placing height of projector, when needing words that the position of projection changes to some extent, people need again to change the placement location of projector, because projector has certain weight, move to get up not to be to facilitate especially, so just to people, use projector to bring certain inconvenience.
For solving the problems of the technologies described above, the necessary projection arrangement that provides a kind of height to regulate, to overcome described defect of the prior art.
Utility model content
The purpose of this utility model is to provide the projection arrangement that a kind of a kind of height simple in structure can regulate.
The purpose of this utility model can realize in the following manner:
The projection arrangement that a kind of height can regulate, comprise base (1), connecting link one (2), connecting link two (3), projector (4), wheel (5) and fixed bar (6), it is characterized in that being connected with on the top of base (1) connecting link one (2) of hollow, the bottom of projector (4) is connected with the connecting link two (3) of hollow, the girth of connecting link two (3) is less than the girth of connecting link one (2), symmetrically on the diameter of connecting link one (2) top circumference be provided with two circular holes, at the upper circular hole that is provided with one group of symmetry every (5) centimetre of connecting link two (3), connecting link one (2) and connecting link two (3) circular hole size are above identical, fixed bar (6) can be simultaneously through the circular hole on connecting link one (2) and connecting link two (3), on four angles of the bottom of base (1), be provided with wheel (5).
The utility model compared with prior art has the following advantages: owing to adopting, projection arrangement is arranged to the convenient mobile and convenient structure that regulates height, so just can uses projector to bring great convenience to people.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
In figure: 1, base; 2, connecting link one; 3, connecting link two; 4, projector; 5, wheel; 6, fixed bar.
Embodiment
As follows with reference to accompanying drawing 1:
The projection arrangement that a kind of height can regulate, comprise base 1, connecting link 1, connecting link 23, projector 4, wheel 5 and fixed bar 6, it is characterized in that being connected with on the top of base 1 connecting link 1 of hollow, the bottom of projector 4 is connected with the connecting link 23 of hollow, the girth of connecting link 23 is less than the girth of connecting link 1, make connecting link 23 can insert connecting link one 2 the insides, symmetrically on the diameter of connecting link one 2 top circumference be provided with two circular holes, on connecting link 23 every 5 centimetres of circular holes that are provided with one group of symmetry, connecting link 1 and connecting link 23 circular hole size are above identical, fixed bar 6 can be simultaneously through the circular hole on connecting link 1 and connecting link 23, when setting the height of projector 4, people are fixed by fixed bar 6 like this, meanwhile, on four angles of the bottom of base 1, be provided with wheel 5, people just can move this projection arrangement by slip wheel 5 like this, and the utility model is simple in structure, are easy to manufacture.
Above embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
