Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cutaway view of steel ball locking disk.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
As shown in Figure 1 and Figure 2, this a kind of novel elevating rotational structure comprises handle 1, joystick 2, first quarter moon platform 3, spring 4, pedestal 13, guiding mechanism 6, steel ball 7, steel ball locking disk 8, pedestal sleeve pipe 9, steel ball lock collar 10, lockout mechanism loam cake 11, connection pipe 12;
One end of joystick 2 is captiveed joint with handle 1, and the other end is captiveed joint with steel ball lock collar 10 with first quarter moon platform 3;
First quarter moon platform 3 is semicircle, and first quarter moon platform 3 lower ends are provided with lockout mechanism loam cake 11;
One end of connection pipe 12 links to each other with lockout mechanism loam cake 11, and steel ball locking disk 8 fixed covers are at the other end of connection pipe 12; Be provided with spring 4 in the connection pipe 12, be provided with guiding mechanism 6 in the spring 4, to prevent spring 4 teeters, spring 4 one ends link to each other with lockout mechanism loam cake 11, and the other end links to each other with pedestal 13; Also can be provided with steel cable 5 in spring 4, steel cable 5 one ends link to each other with lockout mechanism loam cake 11, and the other end passes guiding mechanism 6 and links to each other with pedestal 13;
Steel ball locking disk 8 is arranged in the steel ball lock collar 10, is provided with steel ball 7 on the ramp 81 of steel ball locking disk 8, in steel ball lock collar 10 bottoms and be positioned at same horizontal surface and be provided with the hole 101 that is complementary with steel ball 7, is provided with groove 82 on the top of steel ball locking disk 8;
Preferably, 5 holes 91 of pedestal sleeve pipe 9 longitudinal directions, 4 holes 91 of horizontal direction.Hole 101 numbers on the steel ball locking bushing 10 are identical with steel ball 7 numbers.
The rotation work mode:
Pull handle 1, by joystick 2, first quarter moon platform 3 inclinations 45 degree, press down lockout mechanism loam cake 11, because steel ball locking disk 8 links to each other with lockout mechanism loam cake 11 by connecting 12, steel ball locking disk 8 is also along with moving down, the steel ball 7 that is provided with on the ramp 81 of steel ball locking disk 8 is loosening, and this moment, steel ball 7 left the hole 91 on the pedestal sleeve pipe 9, and the seat of ining succession on the steel ball lock collar 10 rotates, steel ball lock collar 10 is being with steel ball 7 to rotate, after the release handle 1, under the application force of spring 4, steel ball locking disk 8 rising steel balls 7 arrive steel ball locking disk 8 bottoms, enter the hole 91 on the pedestal sleeve pipe 9, locking.
The minimum angles of rotating is relevant with well-distributed steel ball number on the steel ball locking disk 8, and steel ball is many more, and the minimum angles of rotation is more little, preferred here 8 steel balls 7.
The lifting mode of operation:
Pull handle 1, by joystick 2, first quarter moon platform 3 inclinations 90 degree, steel ball locking disk 8 down distance is bigger, steel ball 7 does not break away from the form in the hole 101 on the steel ball lock collar 10 with steel ball 7, with respect to the groove 82 that moves on to steel ball locking disk 8 tops on the ramp 81, the hole 91 that steel ball 7 breaks away from the pedestal sleeve pipe 9, at this moment, steel ball dowel disc 8 can free lifting under the effect of the power of spring 4, drive the 10 also liftings thereupon of steel ball locking bushing by steel ball 7, thereby release handle 1 back steel ball 7 under the application force of spring 4 is ejected locking in the hole 91 that comes back on the pedestal sleeve pipe 9 by steel ball locking disk 8.
Though the utility model with preferred embodiment openly as above; but they are not to be used for limiting the utility model; anyly be familiar with this skill person; in the spirit and scope that do not break away from the utility model; can do various variations or retouching from working as, what therefore protection domain of the present utility model should be defined with the application's claim protection domain is as the criterion.
