Fig. 2 is a coaxial rotation assembly structure scheme drawing of the present utility model;
Fig. 3 is the side cut-away view of Fig. 2;
Fig. 4 is an outer rotary cylinder scheme drawing of the present utility model;
Fig. 5 is the spiral slide scheme drawing in the outer rotary cylinder.
The specific embodiment
Referring to figs. 1 through Fig. 5, a kind of suction top folding display, its structure comprises telltale 1 and inhales top base 2, telltale 1 and suction top base 2 flexibly connect by coaxial rotation assembly 3, and coaxial rotation assembly 3 comprises: be installed in the motor of inhaling on the top base 2 31, machine shaft is installed with screw rod 32, on screw rod 32, be with a columniform slide block 34, the surface of slide block 34 is embedded with steel ball 33, and the outside face at slide block has groove 34a vertically, be with in the outside of slide block to be fixed on and inhale top base upper bracket tube 35, rack tube 35 has groove 34a corresponding to the position of steel ball 33, make steel ball 33 can protrude outside the groove, inside face at rack tube 35 is provided with the convex tendon 35b that matches with groove 34a, and rack tube 35 outsides also are with outer rotary cylinder 36, and outer rotary cylinder 36 is captiveed joint with telltale 1, the inwall of outer rotary cylinder 36 is provided with and can just be fit to the spiral slide 36a that steel ball embeds, and rack tube 35 correspondence position at rotary cylinder two ends is outside established steady ring.
When motor 31 when rotated, the screw rod 32 that is installed on the machine shaft rotates synchronously, be enclosed within the slide block 34 on the screw rod owing to be subjected to the constraint of rack tube convex tendon 35b, can only move vertically, its steel ball 33 that is embedded in outside face acted on spiral ramp 36a simultaneously when slide block 34 moved, because outer rotary cylinder is subjected to the restriction of two ends steady ring 37, forces it can only carry out rotation in situ, thereby make the telltale 1 of captiveing joint open or close with outer rotary cylinder 36.
In addition, inhale the top base and be provided with hydraulic control system, hydraulic control system comprises hydraulic actuating cylinder 41, stretch out the outer pull bar 42 of hydraulic actuating cylinder, pull bar is provided with locating piece 43, on suction top base, left and right sides travel switch 44 is installed corresponding to locating piece, 45, the other end of pull bar 42 is connected with outer rotary cylinder 36 by movable Rocker arm 46, when outer rotary cylinder 36 drives telltale 1 upset, act on pull bar 42 by Rocker arm 46 simultaneously, pull bar is moved forward and backward, when telltale is turned to when spacing, locating piece 43 on the pull bar just acts on one of them travel switch, cuts off this direction motor rotating control system; The design's hydraulic control system also plays booster action when the folding of telltale, when the telltale that closes when opening, because the effect of gravity, the excessive velocities that telltale is opened, can damage Transmission easily, this moment, hydraulic efficiency pressure system played the effect of buffering, when the telltale of opening when closing, same because the effect of gravity, make the duty ratio of motor bigger, motor breaks down easily, and the hydraulic actuating cylinder of this moment is owing to have certain thrust after opening, but helper motor easier closes telltale, and being exempted from motor burns because of excess current.
For the mechanical structure that makes coaxial rotation assembly more reasonable, the design's inwall of rotary cylinder 36 outside mills out three sizes spiral slide 36a the same with lines, spiral slide 36a rotates to the other end from an end of outer rotary cylinder inwall, the angle of every its two vertical lines from the end points to the line of centers of slideway is 120 °, be symmetrically arranged with three groups of steel balls 33 at the slide block outside face accordingly, at rack tube three corresponding groove 35a in the position with steel ball are set, when steel ball 33 when the end of spiral slide 36a slides into the other end, the telltale that is driven by rotary cylinder just detours 120 °, just the stroke of the required rotation of ceiling type telltale.
More than design is an optimal way of the present utility model, and the quantity of its spiral slide also can adopt two or many, can realize making the purpose of telltale folding equally; It is coaxial more fixing from the shared when mounted space of rotation structure for the design, can not be subjected to the influence of size of display, thereby make the surface structure of product more reasonable; In addition, rotating mechanism of the present utility model is sealed in the sleeve, and its lubricating oil is not easy mummification, and compact conformation is saved the space.
