Description
Technical field
The present invention relates to convertible cultural spreading equipment, particularly relate to LED turn-over display screen, convertible lamp box, three faces turn over equipment.
Background technology
At present, convertible LED display, convertible lamp box, three faces the cultural spreading equipment such as to be turned over and are used widely.It by one group independently rectangular triangular pipe regularly arrange and form, the face of triangular pipe is provided with LED light module or description picture, often prop up triangular pipe to be connected with the turning device in box frame respectively, by the Pattern Reversal of setting under motor drives, realize many changing pictures.In existing equipment, most turning device is by pulling out wheel and the engaged wheel of two three horn ring alternate angle overlaps forms, and motor drives and pulls out wheel and rotate, and pull out wheel and often rotate an astragal and move engaged wheel and rotate an angle, the triangle tubing of correspondence then rotates a face.This turning device has the advantage that structure is simple, cost is low.
By one group of independently face of forming of triangular pipe, its flatness depends on initiatively pulls out gap between wheel with three horn rings.In existing product, great majority all adopt dipstick metering or visual method adjustment to pull out the spacing of taking turns between engaged wheel, fixedly wheel is pulled out again by four asymmetrical screw, owing to there is structural defect, easily there is following point: one is adjust to pull out between wheel with engaged wheel to be difficult to be transferred to unified and rational gap, cause the triangular pipe be connected to swing, affect the rollover effect of picture; Two is be in operation, and the reacting force pulled out between wheel and three horn rings makes gap become large gradually, also can cause above-mentioned phenomenon; Three is triangular pipe may be caused stuck under strong wind weather or other External Force Acting, and this phenomenon easily causes transmission shaft knob to break or motor damage, and this is common phenomenon in existing convertible cultural spreading equipment.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of easy for installation, stable a kind of convertible player with elastic reset device.
For solving the problems of the technologies described above, present invention employs a kind of convertible player with elastic reset device, being made up of for the bearing seat of fixed triangle pipe lower end, the slave unit being arranged on box type frame inside and drive unit for the rotary positioning apparatus of fixed triangle pipe upper end, lower frame and being arranged on lower frame side plate a group of arranged in parallel triangular pipe, upper side frame for installing LED light module or sticker picture and being arranged on upper side frame side plate; Described slave unit is made up of large three horn rings of alternate angle overlap and little three horn rings and driven shaft; Described drive unit is formed by pulling out wheel, main shaft and being placed on the axle sleeve pulled out between wheel, main shaft, described in pull out wheel in its structure of disc and by central shaft hole, take turns and form along adjacent and on same centripetal line trapezoidal projection inside upper splay spacing breach and wheel hub with at the bottom of described spacing breach; During assembling: the driven shaft of described slave unit is connected through described bearing seat with described triangular pipe lower end, it is inner that described drive unit is horizontally installed in described box type frame, the angle of large three horn rings of described slave unit and the described spacing breach pulling out wheel suitable, the little three horn ring limits of described engaged wheel and the described trapezoidal projection pulling out wheel are by flat.A kind of guiding mechanism of energy relative sliding is had between described main shaft and axle sleeve; Described axle sleeve is a kind of wheel shaft structure, the axle body that this axle sleeve is extended to the other end by the wheel of axle sleeve and being connected with the wheel of axle sleeve, the shaft shoulder, axle journal, axle head are formed, and having elastic reset device at the described shaft shoulder, axle journal, axle head position, this elastic reset device is connected is formed by loose collar, spring, set collar; Pull out described in the little three horn ring lower central positions of described slave unit have a kind of position-limit mechanism of protrusion, this position-limit mechanism to be embedded in be realized by the elastic force of described spring between the wheel of described axle sleeve and described loose collar and take turns spacing or reset.
After adopting this structure, spring force makes to pull out wheel and keeps controlled, rational gap with engaged wheel, further improves the operational reliability of turning device and the flatness of picture; Under running into strong wind weather or other External Force Acting, the angle of large three horn rings of slave unit and little three horn rings makes to pull out the outside translation of wheel, and after failture evacuation, springback power makes to pull out wheel and resets, and this avoid and causes transmission shaft knob to break or motor damage because triangular pipe is stuck.
As a further improvement on the present invention, described guiding mechanism forms by the raised line of the groove of described main shaft and inner hole of shaft sleeve circumferential wall is suitable, and keep the gap of level and smooth movement.
As a further improvement on the present invention, the axle body from the wheel of axle sleeve to the other end, the shaft shoulder, axle journal, the descending staircase structure reduced step by step of axle head that extend from of described axle sleeve; The described shaft shoulder is the conically structure of transition between axle body and axle journal; Elastic reset device can be made like this to coincide on axle sleeve more tight, slide more flexible.
As a further improvement on the present invention, described axle head circumferentially has 4 symmetrical convex shape projections; The loose collar endoporus of described elastic reset device conically and suitable with the shaft shoulder.The set collar endoporus of described elastic reset device circumferentially have the concave shape projection that on a kind of and described axle head, convex shape projection coordinates.Rotation fixed ring can realize fixing or unclamp, this fixed sturcture, and not only structure is simple, and installation also facilitates.
As a further improvement on the present invention, described position-limit mechanism can be a kind of wheel shaft of flexible rotation, and this wheel shaft is arranged on by rivet on the driven shaft port that exposes below little three horn rings.
Described position-limit mechanism can also adopt a kind of bearing, and this bearing is arranged on the driven shaft that exposes below little three horn rings.Such structure can reduce the friction of initiatively pulling out between wheel and engaged wheel, runs more flexible.
In sum, the present invention can not only guarantee the flatness of picture, avoids simultaneously and causes transmission shaft knob to break or motor damage because triangular pipe is stuck, have easy for installation, the advantage of flexible operation, working stability, effectively reduction failure rate.
