The propeller is formed by splicing two small parts, and not only is the utilization rate of hardboard increased, but also the variability and the playability of the puzzle are enhanced.

Description

A kind of screw of cubic pasteup

Technical field

The utility model relates to a kind of screw of cubic pasteup.

Background technology

Picture arrangement game is very popular a kind of riddle, it changeful, and difficulty differs, and allows people's hundred objects for appreciation not mind.

Modern cubic pasteup, mostly take hardboard as manufactured materials, cuts out the various widgets of picture mosaic on hardboard, but parts as screw, if do not split, the utilization rate that can reduce hardboard, increases cost, also can reduce variability, the playability of picture mosaic.

Utility model content

The purpose of this utility model is to provide a kind of screw of cubic pasteup, solves the above-mentioned problems in the prior art.

The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of screw of cubic pasteup, comprise upper blade group and lower blade group, described upper blade group comprises center pentagon and two blades, described two blades are around the pentagonal central distribution in described center, the angle of described two blades is 72 degree, pentagonal two junctions in described two blades and described center are pentagonal two adjacent angles, described center, and described center is respectively equipped with projection on pentagonal five limits;

Described lower blade group comprises central circular and three blades, described three blades distribute successively around the center of described central circular, the angle of described adjacent two blades is 72 degree, in described central circular, there are five through holes that coordinate with described projection, described 5 through holes were around described central circular one week and be uniformly distributed, described through hole is identical to the distance at pentagonal center, described center with pentagonal one side, described center to the distance at the center of described central circular, there is a described through hole at the place, center of two contact points of described adjacent two blades and described central circular.

The beneficial effects of the utility model are: the utility model provides a kind of screw of cubic pasteup, assembled cleverly by 2 widgets, have both increased the utilization rate of hardboard, have also increased variability and the playability of picture mosaic.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of the upper blade group of the screw of a kind of cubic pasteup of the utility model;

Fig. 2 is the schematic diagram of the lower blade group of the screw of a kind of cubic pasteup of the utility model;

Fig. 3 is the schematic diagram of the screw of a kind of cubic pasteup of the utility model.

In accompanying drawing, the list of parts of each label representative is as follows:

1, blade, 2, center pentagon, 3, projection, 4, central circular, 5, through hole.

The specific embodiment

Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of screw of cubic pasteup, comprise upper blade group and lower blade group, described upper blade group comprises center pentagon 2 and two blades 1, described two blades 1 are around the central distribution of described center pentagon 2, the angle of described two blades 1 is 72 degree, and two junctions of described two blades 1 and described center pentagon 2 are the angle that two of described center pentagon 2 are adjacent, on five limits of described center pentagon 2, are respectively equipped with projection 3;

Described lower blade group comprises central circular 4 and three blades 1, described three blades 1 distribute successively around the center of described central circular 4, the angle of described adjacent two blades 1 is 72 degree, in described central circular 4, have five with described protruding 3 through holes that coordinate 5, described 5 through holes 5 were around described central circular 4 one weeks and be uniformly distributed, described through hole 5 is identical to the distance at the center of described center pentagon 2 to the distance at center and one side of described center pentagon 2 of described central circular 4, described adjacent two blades 1 have a described through hole 5 with the place, center of two contact points of described central circular 4.

During picture mosaic, from hardboard, take out upper blade group and lower blade group, projection in upper blade group 3 is to 90 degree to the mating surface bending of top vane group and lower blade group, upper blade Zu center pentagon 2 is close to the central circular 4 of lower blade group, and the angle that makes adjacent two blades 1 is 72 degree, by each protruding 3, insert respectively corresponding through hole 5 again, to reach fixing effect, picture mosaic completes.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
