Embodiment

The utility model relates to the locking linkage structure that two parts can be connected together, and for example in plastic toys picture mosaic or assembling plastic toys robot, can adopt locking linkage structure of the present utility model in the time of two component-assembled need being got up.

In the preferred embodiment as shown in Figure 1 to Figure 3, the locking linkage structure comprises first parts 1, second parts 2 and screens pin, and the key that is used for pulling down the screens pin.

As shown in Figure 1, the screens pin has the shank 31 of circular shaft shape and is connected the head 30 of shank 31 1 ends, and the radial dimension of head 30 is obviously greater than the diameter of shank 31.The cylndrical surface of shank 31 the other ends is provided with the projection 310 of projection, in the present embodiment, as shown in Figure 1, is arranged with two projections 310 on the cylndrical surface, is the 360 degree angles that 180 degree are divided circumferential surface equally.For attractive in appearance and reduce the friction, with projection 310 be designed to by the light source curved surface constitute, the little taper type in big top, bottom.Offer the shrinkage pool 300 of six prisms on head 30 end faces of screens pin.

As shown in Figure 2, fixedly connected or one-body molded locking sleeve 10 to first parts 1, its internal surface has an inner cylindrical surface S10, the end end of inner cylindrical surface S10 is positioned at the outer surface of locking sleeve 10, the other end end and a toroidal surface S15 join, toroidal surface S15 is coaxial and internal diameter and inner cylindrical surface S10 equal diameters with inner cylindrical surface S10, and promptly inner cylindrical surface S10 and toroidal surface S15 form the right angle.Offer spirality chute 100 on the inner cylindrical surface S10, promptly chute 100 extends to the through toroidal surface S15 in the other end end from the end end of inner cylindrical surface S10.The extension curve of chute 100 is a helix, helix herein be meant when a point moves along straight line around a parallel with it rotational the track of process.

Corresponding with two projections 310 of screens pin, locking sleeve 10 internal surfaces have symmetrically arranged two the spirality chutes 100 in center.On second parts 2, offer through hole 20, and the aperture of through hole 20 is less than the head 30 of screens pin, and the distance between shank 31 and two projection 310 summits is also less than through hole 20 apertures.

During assembling, second parts 2 cooperate with first parts 1 makes through hole 20 just in time align with the inner cylindrical surface S10 of locking sleeve 10, and through hole 20 is coaxial with inner cylindrical surface S10.The screens pin inserts 20, two projections 310 of through hole and can just slip in two chutes 100, and is terminal mobile to inner cylindrical surface S10 in rotation.When moving to chute 100 ends, continue rotation screens pin, then projection 310 leaves chute 100 and rotates on toroidal surface S15, the projection 310 of screens this moment pin is propped up and can not be pulled out by toroidal surface S15, owing to head 30 is against on first parts, 1 surface greater than through hole 20, then the screens pin by head 30 and projection 310 with first parts 1 and second parts, 2 fixing and lockings.

When needs are disassembled first parts 1 and second parts 2, rotation screens pin makes projection 310 turn to chute 100 ends and enters chute 100, draw the screens pin along the simultaneously outside application of force of spirality chute 100 rotations, projection 310 until the screens pin leaves chute 100, then the screens pin is split out, and first parts 1 and second parts 2 can separate.

Need to prove, projection 310 of the present utility model and chute 100 are not defined as two, wherein, one, three of projection 310 cocoas or more than the three, as long as have the chute 100 of corresponding individual and same angular distribution, each projection 310 be can realize in the chute of correspondence before the spiral and then be locked in the locking sleeve 10, thereby first parts 1 and second parts 2 connected;

In addition, locking sleeve 10 can be the formed sleeve-shaped of structure characteristic on first parts 1, also can be independent part, by being installed to a part that becomes first parts 1 on first parts 1;

Simultaneously, the inner cylindrical surface S10 end face of second parts 2 might not be connected with a toroidal surface S15, and what substitute toroidal surface S15 can be conical surface or the curved surface angled with inner cylindrical surface S10; Projection also not necessarily must slide into chute 100 terminal and be against toroidal surface S15 or other can touch to the surface on, its can be located immediately in the chute 100 and by projection 310 surfaces with the friction of chute 100 internal surfaces positioning and lockings;

In order to reduce the workload of knob screens pin, the pitch of the spirality chute 100 in the utility model, be each period of rotation the axial length of process relatively large, thereby make that the number of turns of rotation is less, for example, the pitch of spirality chute 100 is greater than the axial length of described inner cylindrical surface S10, or greater than 1/2nd of axial length, then rotation is no more than two circles, makes simple to operately, reduces the amount of labour.

As Fig. 4, shown in Figure 5, present embodiment is applied on the block toy superman, and as shown in the figure, first parts 1 are superman's main body, and second parts 2 are bearing table, realizes superman's main body is contained on the bearing table by the cooperation between locking sleeve 10 and the screens pin.

As shown in Figure 4, the sole of superman's main body has locking sleeve 10, as previously mentioned, has spirality chute 100 in the locking sleeve 10, then is provided with through hole 20 on the corresponding position of bearing table and inserts wherein for locking sleeve 10.

As shown in Figure 5, for the ease of installing and pulling down the screens pin, present embodiment also has key, and the front end of key has the bottle opener 400 with the suitable hexagon of the shrinkage pool 300 of screens pin head 30.When needing operation screens pin, bottle opener 400 is inserted in the shrinkage pool 300 accordingly, screw key can drive the rotation of screens pin, thus the action that screws or unscrew the screens pin.

Adopt locking linkage structure of the present utility model, utilize the spirality of chute 100, make the screens pin be not easy to drop, if take first and second parts 2 apart, the pin of rotation screens earlier could take out the screens pin, has improved the assembling stability and the not dismounting of two parts; And, if if adorn between first parts 1 and second parts 2 defective tightness, then the projection 310 of screens pin can be against on the chute 100, prevent to unclamp between the two, strengthened assembling stability, although first parts 1 and second parts, 2 assembling backs are placed a very long time and also can not unclamped voluntarily, this is necessary to waiting as toy robot, the automobile furnished after assembling.

In addition, this mode of coming assembly toy with the screens pin has increased the interest of toy, can improve user's liking toy.

In conjunction with the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection of the present utility model.
