As Fig. 1-shown in Figure 4, 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; Being equipped with on the described rotation bracing frame 3 can be with its 5 spacing strut 6 of circular arc that rotate around the shaft, its center of circle and rotating shaft 5 axis coincidings, installing on the U type base 4, away from rotating shaft 5 one sides to supply its center of circle of strut chute 7(of spacing strut 6 slips to overlap with rotating shaft core), this strut chute outer surface one is shaped on vertical with it hollow circular cylinder 8, and install in this cylinder can be along the flexible snap close of cylinder axis direction, realizes the position-limit mechanism of locating on main frame 1 level and the vertical direction automatically being provided with on U type base 4 and the spacing strut 6 with snap fit simultaneously.
As Fig. 5, shown in Figure 6, described snap close comprises spacing spool 9, is enclosed within the outer pressurized torsion spring 10 of this spool, both embed in the hollow circular cylinder 8 from strut chute 7 sides together, wherein spacing spool 9 passes the fixedly connected handle 11 in hollow circular cylinder 8 backs, this handle is a cylinder cup shape, one end opening, the sealing of one end, hollow circular cylinder 8 inserts handle 11 inside from its openend, as shown in Figure 7, pressurized torsion spring 10 is round table-like, and it is fixedlyed connected with spacing spool 9 than small end, and bigger end is fixedlyed connected with hollow circular cylinder 8.
As shown in Figure 8, described hollow circular cylinder 8 surfaces evenly are shaped at least two rank 8-1 that organize a performance, and offer the breach 11-1 that matches with described step 8-1 on the handle 11, and being sheathed on outside the hollow circular cylinder 8 of coincideing.Wherein, described step 8-1 comprises around the first inclined-plane 8-1-1 of hollow circular cylinder 8 surperficial screw arrangement and the second inclined-plane 8-1-2, wherein 8-1-1 lower end, first inclined-plane contacts with strut chute 7 surfaces, the upper end is shaped on the first platform 8-1-3 parallel with hollow circular cylinder 8 end faces, 8-1-2 lower end, second inclined-plane is shaped on the second platform 8-1-4 parallel with the first platform 8-1-3, wherein the second platform 8-1-4 is slightly less than the distance of the first platform 8-1-3 to strut chute 7 surfaces to the distance on strut chute 7 surfaces, thereby forms a limited impression 8-1-5.After breach 11-1 offers and finishes, form corresponding with the first inclined-plane 8-1-1 and the second inclined-plane 8-1-2 respectively first slope 11-1-1 and the second slope 11-1-2, wherein 11-1-1 top, first slope (towards the handle openings end) is shaped on the first spacing preiection 11-1-3 that mates with limited impression 8-1-5, and end is shaped on the first plane 11-1-4 corresponding with the first platform 8-1-3; 11-1-2 top, second slope (towards the handle openings end) is shaped on the second plane 11-1-5 corresponding with the second platform 8-1-4, wherein the first plane 11-1-4 is slightly larger than the distance of the second plane 11-1-5 to handle 11 open ends to the distance of handle 11 open ends, the second spacing preiection 11-1-6 of formation one and limited impression 8-1-5 coupling.
For guarantee that the first spacing preiection 11-1-3 can shift out automatically in limited impression 8-1-5, be shaped on a projection 12 towards strut chute 7 one sides at spacing strut 6 middle parts.When spacing spool 9 through protruding 12 the time, force spacing spool 9 along its axis laterally (towards handle one side) move a certain distance, under 10 effects of pressurized torsion spring, turn an angle simultaneously, make the first spacing preiection 11-1-3 leave limited impression 8-1-5 around axis.
Described position-limit mechanism comprises the through hole 13 that is opened on the U type base 4 corresponding to the snap close position, and be opened in spacing hole 14 on the spacing strut 6, this spacing hole is near the stiff end of rotation bracing frame 3 with spacing strut 6, the central angle that described spacing strut 6 free ends are corresponding with spacing hole 14 folded circular arcs is the right angle, location when the location when wherein spacing hole 14 is used for main frame 1 level, spacing strut 6 free-ended edges are used for the vertical state of main frame 1.
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 15, these torsion spring two ends are individually fixed in U type base 4 and the rotating shaft 5, wherein torsion spring 15 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.
The operation principle of present embodiment is as follows: as Fig. 2-shown in Figure 4, when main frame 1 is in vertical state (folded state), spacing spool 9 ejects, stretch in the spacing hole 14, withstand spacing strut 6 free-ended edges simultaneously, prevent its whereabouts, realize the location, reach the purpose of child-resistant maloperation and alert, prevented the generation of the danger of the fierce impact that causes because of improper operation or rollover; At this moment, the first inclined-plane 8-1-1 and the second inclined-plane 8-1-2 contact with the first slope 11-1-1 and the second slope 11-1-2 respectively, and the second spacing preiection 11-1-6 snaps in the limited impression 8-1-5 simultaneously.When needing rotation main frame 1 to change state, the operator clockwise rotates handle 11, win slope 11-1-1 and the second slope 11-1-2 are slided along the first inclined-plane 8-1-1 and the second inclined-plane 8-1-2, snap in the limited impression 8-1-5 until the first spacing preiection 11-1-3, as Fig. 9-shown in Figure 11, this moment, handle 11 maintained static with respect to hollow circular cylinder 8, simultaneously in the spacing spool 9 retraction hollow circular cylinders 8, lockup state is removed, and pressurized torsion spring 10 is under pressure simultaneously and torsion deforms.As Figure 12-shown in Figure 14, withstand protruding 12 the time when going to spacing spool 9, force spacing spool 9 and handle 11 along its axis laterally (towards handle one side) move a certain distance, make the spacing preiection 11-1-3 that wins leave limited impression 8-1-5, under 10 effects of pressurized torsion spring, turn an angle around axis counterclockwise simultaneously; Spacing strut 6 is rotated further, and spacing spool 9 is removed from projection 12, and the part of win the slope 11-1-1 and the second slope 11-1-2 is contacted with the first inclined-plane 8-1-1 and the second inclined-plane 8-1-2 respectively, and spacing spool 9 withstands spacing strut 6 surfaces simultaneously; When main frame 1 went to level, spacing spool 9 passes spacing hole 14 successively under 10 effects of pressurized torsion spring and through hole 13 is realized the location, and at this moment, the first inclined-plane 8-1-1 and the second inclined-plane 8-1-2 contact with the first slope 11-1-1 and the second slope 11-1-2 respectively.
In like manner, when needs are folded up the mahjong machine, clockwise rotate handle 11, the first spacing preiection 11-1-3 is snapped in the limited impression 8-1-5, and the main frame 1 that manually overturns then gets final product, when main frame 1 goes to vertical state, spacing spool 9 can eject automatically, realizes locking.
