Embodiment
In order to make those skilled in the art person understand better the utility model scheme, below in conjunction with drawings and embodiments, the utility model is described in further detail.
Referring to Fig. 2, the utility model provides a kind of device that The Cloud Terrace horizontally rotates scope that limits, comprise base plate 10, the two ends, left and right of described base plate 10 are arranged at intervals with respectively gear 9 and limiting stopper 12, described gear 9 is connected with described The Cloud Terrace, and described gear 9 is for driving The Cloud Terrace clockwise or being rotated counterclockwise.
In the utility model, referring to Fig. 2, the right-hand member of described gear 9 is installed with driving lever 11, described limiting stopper 12 tops have restraining groove 13, referring to Fig. 2, Fig. 3, described limiting stopper 12 tops are hinged by stationary axle 5 and a block 7, and described block 7 contacts with described driving lever 11, be specially: referring to Fig. 2, described block 7 is positioned at the right-hand member dead ahead of described driving lever 11.
For the utility model, it should be noted that, described driving lever 11 can rotate along with the rotation of gear 9, therefore, position relationship between described driving lever 11 and described block 7 is not unalterable, along with the rotation of driving lever 11, change, for example, driving lever 11 can rotate counterclockwise along with gear 9 the left end dead ahead of described block 7.
Also it should be noted that, the lateral length of described block 7 is greater than vertical width of described restraining groove 13, and described block 7 is limited in the width dimensions of described restraining groove 13 around the scope of stationary axle 5 rotations.
On specific implementation, described stationary axle 5 runs through by described limiting stopper 12 and block 7, described stationary axle 5 screw top are connected with a nut 6, described block 7 is fixed on described limiting stopper 12 by nut 6, therefore, described block 7 can rotate freely round stationary axle 5 (clockwise or be rotated counterclockwise) on described limiting stopper 12, just when being rotated, the rotation amplitude of described block 7 can be subject to the restriction of the restraining groove 13 at limiting stopper 12 tops, when colliding restraining groove 13, will be prevented from continuing rotation.
It should be noted that, on specific implementation, in the lump referring to Fig. 3, the bottom centre position of described limiting stopper 12 has boss 14, described base plate 10 is provided with groove 15 on the position corresponding with described boss 12 (be specially described boss 12 under), the shape of described boss 12, the shape of big or small and described groove 15, the corresponding coupling of size, therefore, by described boss 12 and groove 15, match, can securely described limiting stopper 12 be fixed on base plate 10, prevent that limiting stopper 12 from producing displacement when being subject to external force (as driving lever 11 and block 7 collisions) on base plate 10.
Referring to Fig. 2, described base plate 10 end faces upper and lower symmetrical (being specially transversely center line) that are positioned at described block 7 the right are provided with a right margin optocoupler 1 and a left margin optocoupler 2.The right-hand member of described block 7 is provided with an optocoupler catch 4, and the position of described optocoupler catch 4 is lower than described right margin optocoupler 1 and left margin optocoupler 2, and described optocoupler catch 4 is positioned at the below of described right margin optocoupler 1 and left margin optocoupler 2.
In the utility model, the right-hand member of described block 7 also is connected with the left end of a spring 3, and the right-hand member of described spring 3 is fixedly installed on described base plate 10.On specific implementation, the right-hand member of described spring 3 is positioned on the top cross center line of described base plate 10, therefore, for block shown in Fig. 27 and optocoupler catch 4 be non-horizontal cross place situation the time, 3 pairs of described blocks 7 of spring and optocoupler catch 4 have the pulling force of a centerline direction of the top cross towards described base plate 10.
It should be noted that, for the utility model, when gear 9 drive The Cloud Terraces horizontally rotate clockwise, also will drive driving lever 11 rotates together, when driving lever 11 contacts with block 7, block 7, under the promotion of driving lever 11, will drive optocoupler catch 4 and rotate in the middle of right margin optocoupler 1, thereby, by transmitting control signal to The Cloud Terrace, control The Cloud Terrace and stop the rotation;
If now tripod head power failure and under the effect of certain external force, make The Cloud Terrace continue to turn clockwise, driving lever 11 continues to promote blocks 7 rotations, until block 7 touches the upper side of the restraining groove 13 of limiting stopper 12, block 7 will be prevented from continuing rotation.
After The Cloud Terrace turns clockwise end, gear 9 will drive The Cloud Terrace to be continued to be rotated counterclockwise, and driving lever 11 leaves block 7, under the pulling force of spring 3, block 7 returns to the transverse center line parallel of original position and base plate 10 or overlaps, and optocoupler catch 4 shifts out the right margin optocoupler for next time spacing ready.
When driving The Cloud Terrace, gear 9 continues to be rotated counterclockwise, until, when driving lever 11 contacts with the downside of block 7, block 7, under the promotion of driving lever 11, drives optocoupler catch 4 and rotates in the middle of left margin optocoupler 2, controls The Cloud Terrace and stops being rotated counterclockwise.
If now tripod head power failure and under the effect of certain external force, make The Cloud Terrace continue to be rotated counterclockwise, driving lever 11 continues to promote blocks 7 rotations, until block 7 touches the downside of the restraining groove 13 of limiting stopper 12, will be prevented from continuing rotation.
For the utility model, no matter The Cloud Terrace turns clockwise or is rotated counterclockwise, and when driving lever 11 leaves block 7, it is spacing preferably preparation that optocoupler catch 4 and block 7 will return to home position under the pulling force of spring 3.
In the utility model, on specific implementation, on the edge, left part of described block 7 and the edge, right part of driving lever 11, there is circular arc 8, therefore, when driving lever 11 contacts with block 7, can reduce friction and collision between them.
In addition, the utility model can be by suitably increasing the width of the restraining groove 13 of processing on limiting stopper 12, and the position dimension that changes the angle of right margin optocoupler 1, left margin optocoupler 2, surpass 360 degree thereby can make The Cloud Terrace horizontally rotate scope, namely The Cloud Terrace clockwise and be rotated counterclockwise the angle sum and can surpass 360 degree.
For the utility model, it can be under the condition that meets the The Cloud Terrace security of operation, avoided The Cloud Terrace in the prior art to horizontally rotate the defect that scope is little, on specific implementation, can be according to user's needs, allow the rotating range of The Cloud Terrace can be greater than or equal to 360 degree, therefore, can enlarge markedly the monitoring range of the video monitoring equipments such as vidicon camera of installing on the The Cloud Terrace.
Therefore, in sum, compared with prior art, the utility model provides a kind ofly limits the device that The Cloud Terrace horizontally rotates scope, it not only can guarantee the security of operation of The Cloud Terrace, can also significantly increase the scope that horizontally rotates of The Cloud Terrace, increases the monitoring range of the video monitoring equipments such as vidicon camera of installing on The Cloud Terrace, be conducive to production application widely, be of great practical significance.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
