Description

Torsion spring type folds the mahjong machine

Technical field

The utility model relates to a kind of automatic mahjong machine, and particularly a kind of torsion spring type folds the mahjong machine, is applicable to that mainly family, chess and card room etc. are for people's amusement.

Background technology

Collapsible mahjong machine in the market mainly contains two classes, and a class is the electric foldable formula, and a class is manually collapsible, and electrodynamic type is no doubt easy to operate, safety, but it is bigger to drive the folding most power ratio of motor of mahjong machine fuselage, and cost is than higher; And it is manual collapsible most of simple in structure, though can save the space after machine is folding, because of there not being power assisting device, the deficiency of existence is to want the strength of armrest arm to realize folding fully, because mahjong machine fuselage is heavier, artificial folding have certain degree of difficulty and danger; And even if the manual folding base of power assisting device arranged, structure more complicated mostly, cost is than higher.

Summary of the invention

The technical problems to be solved in the utility model is: the problem at above-mentioned existence provides a kind of torsion spring type simple in structure, easy to operate, that cost is low folding mahjong machine, reduces folding difficulty and danger, convenient folding purpose to reach.

The technical scheme that the utility model adopted is: torsion spring type folds the mahjong machine, comprise main frame and U type base, wherein the main frame lower surface is installed electric cabinet, this electric cabinet is partially submerged in the U type groove of U type base, described electric cabinet both sides are provided with two rotation bracing frames of fixedlying connected and being parallel to each other and arranging with main frame, each rotates bracing frame and all adopts rotating shaft and U type base top one side hinged, it is characterized in that: described rotating shaft one end is fixedlyed connected with the rotation bracing frame, the other end passes behind the axis hole on the U type base with outer shaft sleeve one torsion spring, and these torsion spring two ends are individually fixed in U type base and the rotating shaft.

Offer on the described U type base, near the hinged place and be parallel to the spacing hole that rotating shaft is arranged, in the rotating shaft simultaneously, radially offer stopper slot away from rotation bracing frame one end, the torsion spring two ends are inserted respectively and are realized the location in spacing hole and the stopper slot.

Described torsion spring is in the raw the time, and main frame is in heeling condition.

The center of gravity of described main frame and the axle center of rotating shaft are positioned at same perpendicular.

The beneficial effects of the utility model are: the utility model rotating shaft one end is fixedlyed connected with the rotation bracing frame, the other end pass realize behind the axis hole on the U type base hinged, rotating shaft simultaneously is with outer shaft sleeve one torsion spring, these torsion spring two ends are individually fixed in U type base and the rotating shaft, when torsion spring in the raw the time, angle between main frame and the base is an acute angle, with this state is original state, no matter be to horizontal direction (user mode) rotation or to vertical direction rotation (folded state) with main frame, torsion spring all can produce the part gravity that certain torsion is offset main frame accordingly, with respect to electric foldable mode of the prior art, saving motor, when reducing cost, guaranteed folding security; With respect to manual folding mode of the prior art, not only operating process is more laborsaving, difficulty when having reduced manually-operated and danger, and also simple and practical.

The specific embodiment

As shown in Figure 1 and Figure 2, present embodiment comprises main frame 1 and U type base 4, wherein main frame 1 lower surface is installed electric cabinet 2, this electric cabinet is partially submerged in the U type groove of U type base 4, described electric cabinet 2 both sides are provided with two rotation bracing frames 3 of fixedlying connected and being parallel to each other and arranging with main frame 1, and each rotates bracing frame 3 and all adopts rotating shaft 5 and U type base 4 tops one side hinged; 5 one ends of rotating shaft described in this example are fixedlyed connected with rotation bracing frame 3, the other end passes behind the axis hole on the U type base 4 with outer shaft sleeve one torsion spring 6, these torsion spring two ends are individually fixed in U type base 4 and the rotating shaft 5, wherein torsion spring 6 lateral surface that is positioned at U type base 4 (also can be positioned at the medial surface of U type base, only however influence electric cabinet in U type groove, rotate get final product), rotate the medial surface that is positioned at U type base of 3 correspondences of bracing frame.For guaranteeing the normal folding of mahjong machine, the degree of depth of above-mentioned U type groove should be enough, to guarantee that electric cabinet 2 can not run into U type base 4 in the folding process.

As shown in Figure 3-Figure 5, offer on the described U type base 4, near the hinged place and be parallel to the spacing hole 7 that rotating shaft 5 is arranged, simultaneously in the rotating shaft 5, radially offer stopper slot 8 away from rotation bracing frame 3 one ends, torsion spring 6 two ends are inserted respectively in spacing hole 7 and the stopper slot 8 and are realized the location.

When described torsion spring 6 in the raw the time, the angle of main frame 1 and horizontal direction αBe acute angle (U type base is positioned on the horizontal plane) that promptly main frame 1 is in heeling condition with respect to U type base 4; As preferred version wherein, when torsion spring 6 in the raw the time, the angle between main frame 1 and the base 4 αBe acute angle, the center of gravity of main frame 1 and the axle center of rotating shaft 5 are positioned at same perpendicular simultaneously.

Now with torsion spring 6 in the raw the time, it is that example illustrates its operation principle that the axle center of the center of gravity of main frame 1 and rotating shaft 5 is positioned at this preferred version of same perpendicular, (torsion spring in the raw with this state, the center of gravity of main frame and the axle center of rotating shaft are positioned at same perpendicular simultaneously) be original state, when needs use the mahjong machine, the operator only need promote main frame 1 to horizontal direction rotation (going to user mode), after main frame 1 turns an angle, the center of gravity of main frame 1 moves to a side (the decline end of this side and main frame is positioned at the same side of rotating shaft place perpendicular) of rotating shaft 5 place perpendiculars, main frame 1 original balance is broken, make main frame 1 under the self gravitation effect, rotate from the trend horizontal direction, this moment, torsion spring 6 deformed, produce certain torsion simultaneously and delay the decrease speed that main frame 1 descends and holds, clashing of when having avoided causing main frame 1 to go to level and base 4 tops, thereby the difficulty when having reduced manually-operated because of main frame 1 is overweight; In like manner, when needs are folded up the mahjong machine, the operator only need promote main frame 1 and rotate to vertical direction (going to folded state), after main frame 1 turns an angle, the center of gravity of main frame 1 moves to the opposite side (the decline end of this side and main frame is positioned at the same side of rotating shaft place perpendicular) of rotating shaft 5 place perpendiculars, main frame 1 original balance is broken, make main frame 1 under the self gravitation effect, rotate from the trend vertical direction, this moment, torsion spring 6 deformed, produce certain torsion simultaneously and delay the decrease speed that main frame 1 descends and holds, clashing of when having avoided causing main frame 1 to go to vertical state and base 4 sides, thereby difficulty and danger when having reduced manually-operated because of main frame 1 is overweight.
