Abstract

The utility model relates to a simple combined structure for magic block bearings, which belongs to the field of an intelligence toy. The utility model mainly comprises a plurality of groups of bearings with three-dimensional space axial configuration, and spin blocks, wherein the extending front end of the bearing in each channel is provided with the non-return clamping structure of a tapered head, a round ball head, a cambered ball head with a bulge ring, etc.; the inner side of the spin blocks is provided correspondingly with spindle sleeves matched with the front end parts of the bearings; the walls of the spindle sleeves are provided with slots; the inner part of the spindle sleeve, which is penetrated on the spin block by making use of the front end part of the bearing, forms the clamp pivot structure of the blocks pivoted on the bearings without loosing and dropping. The utility model has the advantages of ingenious and simple members, easy and quick assembling, and low cost, and is effective to promote the productivity.

Description

The easy combining structure of magic block bearing

The utility model is a kind of easy combining structure of magic block bearing, belongs to the puzzle field.

Though magic block comes out for many years, but since it warm interesting with can train mental multi-functional, be still long lasting, generally being subjected to popular institute likes, and with regard to manufacturing firm, be constantly it to be made, in the assembling or operational configuration aspects study improvement, in the hope of reaching better boundary.At present, in the structure of magic block, main portions still is the six road bearings of three-dimensional space axial arrangement (being X-axis, Y-axis and Z axle) and the combination of each spill spin block, the structure that tradition is old-fashioned.The combination of spill spin block and bearing in this kind structure, it is sheathed packing ring of bolt of utilization, pass spill spin block behind the spring and lock in the bearing, and also must build again a bonding top board on the spill spin block surface, this kind structure assembling trouble, member is various and production efficiency is low, also has the situation of the screw debentition of bearing sometimes, cause loosely organized damage, undesirable especially.

The purpose of this utility model is exactly to improve at the traditional structure of this kind, provides a kind of member of simplifying significantly, the easy combining structure of the easily assembled bearing of magic block rapidly.

The purpose of this utility model is achieved in that it mainly comprises plural groups bearing and spill spin block with the three-dimensional space axial arrangement, wherein the leading section of each road bearing extends the nonreturning clamping structures such as arc ball head that are provided with Dou conehead, ball head, have prominent ring, and the inside correspondence of spill spin block is provided with the axle sleeve that can cooperate with this bearing leading section, the jacket wall of this axle sleeve has been opened groove, utilization axle leading section places the axle sleeve inside into spill spin block, form spill spin block on bearing, the blocking structure that pivot and nothing get loose and drop.

Advantage of the present utility model is: 1. member is few, thereby cost saving reduces manufacturing cost effectively; 2. simple and convenient assembly is rapid, shortens the manufacturing cycle, has improved productivity ratio; 3. firmly how to use.

Description of drawings:

Fig. 1 is the decomposing schematic representation of the utility model bearing and spill spin block

Fig. 2 is the combination dissected figure of the utility model Dou pan head shape bearing and spill spin block

Fig. 3 is the combination dissected figure of the utility model ball head shapes bearing and spill spin block

Fig. 4 is the combination section diagrammatic sketch of the utility model arc ball head shape bearing and spill spin block

Below in conjunction with drawings and Examples the utility model is done further carefully to state:

The utility model comprises with the plural groups bearing 10 of three-dimensional space axial arrangement and is mated into the clamping structure of tool nonreturning, the shape of the Dou conehead 11 as shown in figure one, two, the shape of the ball head 12 shown in the figure three, arc ball head 13 shapes shown in Fig. 4 with the ring 14 of dashing forward together, and spill spin block 20 is the shape by the inside hollow out in bottom, central interior extend be equipped with one with the axle sleeve 21 of bearing 10 leading section corresponding matching, engrave the aperture trepanning 22 more smaller in this axle sleeve 21, and opened (or multiple tracks) groove 23 together on the jacket wall than inner aperture.Spill spin block 20 gets final product with each road bearing 10 combination, as shown in figure two, three, four, directly spill spin block 20 is aligned the leading section of bearing 10 with its axle sleeve 21, slightly the application of force is pushed, after can making leading section pass the aperture of trepanning 22, pivot is enclosed within trepanning 22 inside, pivot closes the back, and material own is flexible resets owing to axle sleeve 21, the leading section hub setting that makes bearing 10 is in axle sleeve 21 time, on the one hand spill spin block 20 must smooth and easy rotation on bearing 10, and both can be the nonreturning clamping structure that exhausted nothing gets loose mutually on the other hand.

Claims

1, a kind of easy combining structure of magic block bearing, mainly comprise with the plural groups bearing of three-dimensional space axial arrangement and the spill spin block that is mated, it is characterized in that: the leading section of bearing extends the nonreturning clamping structure of being arranged to the Dou pan head shape, and spill spin block is by the inside hollow out in bottom, in central interior extend be equipped with one with the axle sleeve of bearing leading section corresponding matching, engrave in this axle sleeve an aperture than internal holes through smaller trepanning, on jacket wall, then opened groove, the leading section of each bearing wears the card pivot in the axle sleeve trepanning of spill spin block, makes spill spin block and bearing constitute pivotable nonreturning combination.

2, the easy combining structure of magic block bearing according to claim 1, it is characterized in that: the bearing leading section can be the ball head shapes, or is provided with the arc ball head shape of prominent ring together.
