In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
A kind of laser-projector mounting rack of seamless spliced screen, including installation frame body, if the installation frame body byDry unit mounting rack is spliced, and the upside of the unit mounting rack is equipped with two sliding rails, and the downside of the unit mounting rack is rightAnswer sliding rail that idler wheel is set, the rolling route and sliding rail of the idler wheel are symmetrical, and unit mounting rack side is equipped with bayonet unit, phaseTwo adjacent unit mounting racks are connected by clamping apparatus.
Preferably, the bayonet unit includes first connecting rod, the second connecting rod and shackle member, the unit mounting rackSide be equipped with through-hole, the first connecting rod, which is worn, to be connect in through-hole, and one end of the first connecting rod passes through articulation piece and theOne end of two connecting rods is hinged, and the other end of second connecting rod is connected with one end of shackle member, and the shackle member is in arcThe other end of shape structure, the shackle member is equipped with clamping joint.
Preferably, the other end of second connecting rod is connected with one end of shackle member by clamping screw.
The utility model have the characteristics that it is following and the utility model has the advantages that
By adopting the above technical scheme, it can be combined, be used by unit mounting rack according to the actual demand of multi-screen splicingMore flexible, in addition, being provided with the idler wheel and sliding rail matched, assembly is more convenient, and is additionally arranged bayonet unit, so that groupMounting rack after dress is stronger.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodimentOr attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is onlyIt is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor propertyIt puts, is also possible to obtain other drawings based on these drawings.

In figure, 1- unit mounting rack, 2- bayonet unit, 3- sliding rail, 4- idler wheel, 5- through-hole, 21- first connecting rod, 22- hingeFitting, 23- clamping screw, 24- shackle member, 25- clamping joint, the second connecting rod of 26-.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted thatThe explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.ThisOutside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each otherIt can be combined with each other.
The utility model provides a kind of laser-projector mounting rack of seamless spliced screen, as depicted in figs. 1 and 2, packetInstallation frame body is included, installation frame body is spliced by several unit mounting racks 1, and the upside of unit mounting rack 1 is equipped with two cunningsRail 3, the downside of unit mounting rack 1 correspond to sliding rail 3 and idler wheel 4 are arranged, and the rolling route and sliding rail 3 of idler wheel 4 are symmetrical, unit mounting rack1 side is equipped with bayonet unit 2, and two adjacent unit mounting racks 1 are connected by clamping apparatus 2.
In above-mentioned technical proposal, it can be combined by unit mounting rack, according to the actual demand of multi-screen splicing using moreAdd flexibly, in addition, being provided with the idler wheel 4 and sliding rail 3 matched, assembly is more convenient, and is additionally arranged bayonet unit, so that groupMounting rack after dress is stronger.
It should be understood that the idler wheel 4 of the unit mounting rack 1 of top is matched with the sliding rail 3 of the unit mounting rack 1 of lower section,Demand so according to reality to laser-projector assembles, not only easy to operate, and configuration is more reasonable, using moreFlexibly.
The further setting of the utility model, as shown in figure 3, bayonet unit 2 includes first connecting rod 21, the second connecting rod26 and shackle member 24, the side of unit mounting rack 1 is equipped with through-hole 5, and first connecting rod 21, which is worn, to be connect in through-hole 5, first connecting rod21 one end is hinged by articulation piece 22 and one end of the second connecting rod 26, the other end and the shackle member 24 of the second connecting rod 26One end is connected, the arc-shaped structure of shackle member 24, and the other end of shackle member 24 is equipped with clamping joint 25.
In above-mentioned technical proposal, after assembly unit mounting rack 1, the unit mounting rack 1 with assembling pushes the first connectionOne end of bar 21, so that the clamping joint 25 of 24 other end of shackle member can be connected to 1 side of unit mounting rack to be assembled,So that adjacent unit mounting rack 1 assemble it is stronger.
Further, the other end of the second connecting rod 26 is connected with one end of shackle member 24 by clamping screw 23.It is logicalClamping screw 23 is crossed further to be locked, so as to further such that adjacent unit mounting rack 1 assemble it is stronger.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouchedThe embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spiritThese embodiments include that component carries out a variety of change, modification, replacement and modification, still fall within the protection scope of the utility modelIt is interior.
