Abstract

The utility model relates to an improvement for building blocks. The utility model is mainly composed of a muff-coupling rod and a switching element. Both tips of both ends of the muff-coupling rod are respectively provided with an inward concave slot and an annular flange. The switching element is perisphere-shaped, ruggby-shaped or patelliform-shaped. Two or more muff-coupling holes which are used to be sheathed with the muff-coupling rod are arranged on a surface of the switching element. Vent holes are arranged in the muff-coupling holes. The utility model can reduce the friction drag when the muff-coupling rod is inserted into the muff-coupling holes by the arrangement of the slot. The muff-coupling rod can completely get into the muff-coupling holes of the switching element when the muff-coupling rod is inserted into the switching element by the arrangement of the vent holes, and the switching element can also easily be separated from the muff-coupling rod. The utility model has the advantage of easiness and labor saving when sheathing and disassembling.

Description

Improved toy building element

The utility model relates to toy for children, refers to a kind of toy building element especially.

Toy is of a great variety now, building blocks are taught through lively activities and are excited the function of the power of imagination so quite be subjected to the children and the head of a family's favor because of having concurrently, also therefore in toy, occupy suitable deal, general block toy commonly used, for making its interelement energy fluid-tight engagement, minimum when the socket nargin between trepanning and joint is reduced to, make fashionable can not the interspacing of fitting sleeve and with the two elements driving fit and make its difficult drop-off, use and be connected majority element and present more variation; Though above-mentioned building blocks commonly used can be with the element fluid-tight engagement, need expend bigger strength in socket or when decomposing, children's use easily produces difficulty for young age, and take place often can't resolution element because of driving fit too situation.

At the problems referred to above, the purpose of this utility model provides that a kind of setting by groove and passage makes socket and the light improved toy building element in labour-saving when disassembling.

In order to achieve the above object, the improved toy building element of the utility model, it mainly is made up of sleeving connecting rod and switching element, this sleeving connecting rod is equipped with the groove of indent in two end terminals, and establish circular-arc flange, this switching element is spheroidal and (or is American football shape, dish), be provided with plural sleeve joint hole in the surface, put sleeving connecting rod for connecing, and in sleeve joint hole, establish passage, frictional resistance when being provided with of mat groove reduced sleeving connecting rod and inserted sleeve joint hole, and utilize the combination that is connected of plurality of adapter coupling element and sleeving connecting rod, make it get final product set of variations and put out the object of various moulding with easy element.

From above technical scheme, can obviously find out, the utility model utilizes the terminal groove of sleeving connecting rod and has reduced the contact area of itself and sleeve joint hole inner edge, and reach the purpose of can laborsaving assembling and disassembling, and being provided with of mat passage discharged the air in the sleeve joint hole, can avoid to enter fully because of air trapping makes sleeving connecting rod in sleeve joint hole, situation about becoming flexible when easily causing winding, and when detaching sleeving connecting rod, unlikely formation vacuum state in its sleeve joint hole makes the user easily switching element be separated with sleeving connecting rod.

Below now with regard to shape structure of the present utility model, device characteristic and effect thereof, for a preferable feasible embodiment, after conjunction with figs. is described in more detail in, to increase to understanding of the present utility model.

The simple declaration of accompanying drawing drawing:

Fig. 1: be to be structural perspective of the present utility model;

Fig. 2: be to be structural profile schematic diagram of the present utility model;

Fig. 3: be to be action cut-away view of the present utility model;

Fig. 4: be to be enforcement example of the present utility model.

Label declaration in the accompanying drawing:

10 ... sleeving connecting rod 11 ... groove

12 ... flange 20 ... switching element

21 ... sleeve joint hole 22 ... passage

See also shown in Figure 1, the improved toy building element of the utility model mainly is made up of sleeving connecting rod 10 and switching element 20, this sleeving connecting rod 10 is equipped with the groove 11 of indent in two end terminals, and establish circular-arc flange 12 in the in addition end of groove 11, switching element 20 is spheroidal, be provided with plural sleeve joint hole 21 in the surface, put sleeving connecting rod 10 for connecing, the frictional resistance when being provided with of mat groove 11 reduced sleeving connecting rod 10 and inserted sleeve joint hole 21.

See also shown in Figure 2, be generalized section of the present utility model, the sleeve joint hole 21 of switching element 20 is provided with a passage 22 in end terminal, when sleeving connecting rod 10 is inserted sleeve joint hole 21, utilize groove 11 with the contact area of minimizing with sleeve joint hole 21 inner edges, and have than light labour-saving effect, by passage 22 air extrusion remaining in the sleeve joint hole 21 is discharged switching element 20 outsides again, because of making sleeving connecting rod 10 in sleeve joint hole 21, air trapping can't enter fully avoiding, situation about becoming flexible when easily causing winding, and when detaching sleeving connecting rod 10 (as shown in Figure 3), unlikely formation vacuum state in its sleeve joint hole 21 makes the user easily switching element 20 be separated with sleeving connecting rod.

See also switching element shown in Figure 4, above-mentioned 20 again and can be made as and generally be American football shape and dish, and plural sleeve joint hole 21 is set, cooperate the sleeving connecting rod 10 of all lengths, make it can set of variations put out the object of various moulding with easy element.

In sum, the improved toy building element that it provided has really solved the problem that the dust head exists, and overall structure has been had progressive and practicality; Only the above, it only is of the present utility model one preferable enforcement example, when can not with as limiting the scope that the utility model is implemented, all equalizations of being done according to the utility model technique scheme change or modify, and must belong in the scope that the technical solution of the utility model contains.

Claims
