Abstract
The utility model discloses an automatic fast changing device for the billboard with three pictures. The utility model is characterized in that a ratchet mechanism, an intermittent toggle mechanism, and an energy storage spring are arranged between two wallboards fixed by bolts, the energy storage spring can store the energy again and again, and a gear fixedly connected with a ratchet wheel is driven to rapidly rotate. The utility model replaces various intermittent driving devices used by the existing billboards with three pictures, the process of changing and turning the pictures can be completed in moment, having the effect of 'cartoon'. In addition, the utility model has the advantages of compact structure and small size, and is a replacing product of the prior art.
Description
The utility model relates to a kind of mechanical driving device, especially relates to a kind of automatic upset three-picture billboard fast changing device.
Existing automatic upset three-picture billboard, although its face shaping is different, its employed intermittent transmission device is two big classes nothing more than: a class is the mechanical transmission mechanism of electronic timing, another kind of is traditional mechanical type intermittent drive mechanism.Use the billboard of this two classes intermittent transmission device, the reversal rate of picture all depends on the output speed of reductor.Therefore, the existing in prior technology common defects is that image turning is slow (if require image turning fast, just must shorten the interval time of conversion picture) too, weak eye can be seen the process of image turning significantly, and the dull sense of using the turning-over changed picture of mechanical drive is completely exposed.
In view of the existing defective of prior art, the purpose of this utility model is to disclose a kind of image turning speed and the irrelevant quick fast changing device of reductor output speed.
Above-mentioned purpose of the present utility model realizes by following technical solution.
The automatic fast changing device of a kind of billboard is characterized in that being provided with ratchet device and toggle mechanism at intermittence between by bolt two blocks of wallboards together; One of energy-storaging spring links to each other with the bolt of fixing two blocks of wallboards, and the other end links to each other with the ratchet fork; Intermittently toggle mechanism intermittently inhour stir the ratchet fork, make energy-storaging spring accumulation of energy repeatedly, drive the ratchet fork anxious clockwise time, drive end face and connect firmly intermittently racing of cogged ratchet, the technical program replaces the existing employed intermittent transmission device of three-picture billboard, connecting firmly the racing at intermittence of gear together with ratchet, can drive all cell cubes that constitute the three-picture billboard--triangular prism is intermittently upset fast synchronously, the conversion picture.
Because the utility model has adopted with spring energy-storage and has forced the intermittently technical measures of racing of gear, therefore replace the existing used intermittent transmission device of three-picture billboard with the utility model, the process of image turning conversion suddenly can be finished, and has the effect of " cartoon ".In addition, the utility model also has compact conformation, advantage that volume is little, is a kind of renewal product of the existing employed intermittent transmission device of three-picture billboard.

Fig. 2 is the left view of Fig. 1.What double dot dash line was represented among the figure is ratchet fork (4) is pushed extreme position by shift fork (2) synoptic diagram.
Fig. 3 is the A-A partial sectional view of Fig. 2.
Fig. 4 is for using the structural representation of a kind of three-picture billboard of the present utility model.
Embodiment
See figures.1.and.2, left wallboard (14) and right wallboard (6) are fixed together with 4 bolts (15), transmission shaft (1) passes from the center pit of two blocks of wallboards; Upward fix a shift fork (2) with screw (16) at transmission shaft (1), the head of shift fork (2) is established a counterbore, establishes a spring (8) and a compressible spring (8) in the hole and can go here and there moving stub pin (3) in the hole; A sheathed again head is provided with the ratchet fork (4) of ratchet (9), spring leaf (17) and end face is connecting firmly gear (18) with screw (19) ratchet (10) on transmission shaft (1); One with disc spring (5) is inserted in the slit set on ratchet fork (4) the root boss, is hooked on the bolt (15) around other end, transmission shaft (1) 2～3 circle back.Be provided with one section arc skewed slot (7) with reference to Fig. 2 and the right wallboard of Fig. 3 (6).With reference to Fig. 2, apply a moment for transmission shaft (1) and make it counter-clockwise transmission, when shift fork (2) forwarded stub pin (3) with ratchet fork (4) position contacting to, ratchet fork (4) was just followed shift fork (2) and is rotated, and made the bent accumulation of energy of disc spring circle simultaneously.In case ratchet fork (4) forwards position shown in the double dot dash line among the figure to, stub pin (3) will be fallen in the arc skewed slot under the effect of spring (8), lose ratchet fork (4) control action, at this moment, ratchet fork (4) clockwise rotates rapidly by ratchet (9) drive ratchet (10) under the effect of disc spring (5) stretching, extension elastic force.Make moving axis (1) said process of repetition that whenever circles, realize the racing at intermittence of gear (18).With reference to Fig. 4, the racing at clockwise intermittence of gear (18) drives all triangular prisms (24) upset synchronously, intermittently conversion picture by the idle wheel (25) between two triangular prisms (24).
With reference to Fig. 1, establish three blind holes on the gear (18), establish in each hole on the left wallboard (14) of a spring (20) and a positioning ball (21) correspondence position and establish three recesses, to reach the purpose that ratchet (10) and gear (18) can not rotate naturally.
With reference to Fig. 1, on right wallboard (6), establish the blockage (22) of a projection, wear a set screw (23) on the blockage (22), regulate the initial position of ratchet fork (4), guarantee accurately resetting of ratchet fork (4) simultaneously, reach the smooth purpose of billboard picture.
Claims (3)
1, the automatic fast changing device of a kind of billboard is characterized in that being provided with ratchet device and toggle mechanism at intermittence between by bolt two blocks of wallboards together; One of energy-storaging spring links to each other with the bolt of fixing two blocks of wallboards, and the other end links to each other with the ratchet fork; Intermittently toggle mechanism can intermittently be stirred the ratchet fork counterclockwise, makes energy-storaging spring accumulation of energy repeatedly, drives the ratchet fork and suddenly returns clockwise, drives end face and connects firmly intermittently racing of cogged ratchet.
2, the automatic fast changing device of a kind of billboard according to claim 1 is characterized in that left wall and connects firmly being provided with positioning ball and spring between the gear of ratchet end face.
3, the automatic fast changing device of a kind of billboard according to claim 1 and 2 is characterized in that right wallboard is provided with a projection, and projection is provided with ratchet fork location set screw.
