Fig. 2 is the explosive view of video camera front end-plate adjusting device of the present utility model.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.
In the utility model, evenness governor motion and the center adjustment mechanism that will comprise the front end-plate of sensitive chip integrate, make the center that to regulate within the specific limits front end-plate after the evenness of regulating front end-plate, thereby eliminate the black surround phenomenon, simplify regulating step.
The video camera that front end-plate of the present utility model is adjustable comprises the front end-plate of carrying video camera sensitive chip plate and is used for regulating the evenness of front end-plate and the adjusting device of center.As shown in Figure 1, adjusting device for the video camera front end-plate of the present utility model comprises: the evenness adjustable plate 101 of regulating by laser collimator, the center adjustment plate 102 of regulating by the center adjustment instrument, evenness adjustable plate 101 and center adjustment plate 102 lay respectively at the both sides up and down of front end-plate 100, evenness adjustable plate 101 contacts with front end-plate 100, to regulate the evenness of front end-plate 100.Wherein, front end-plate 100 is the sensitive chip plate.What preferably, evenness adjustable plate 101 surfaces had a sensitive chip of dodging front end-plate 100 rats dodges hole 114.
Further, as shown in Figure 2, evenness adjustable plate 101 surfaces have at least two towards the first double-screw bolt 111 of center adjustment plate, and evenness adjustable plate 101 is connected with fastener by the first double-screw bolt 111 and is connected with center adjustment plate 102.Usually, this fastener 112 is the screw that coordinates with the first double-screw bolt 111.
Evenness adjustable plate 101 is fixedly connected with the protecgulum of video camera by a plurality of adjustment screws, and its surface has the screw 115 that passes for adjusting screw.Therefore evenness adjustable plate 101 contacts with front end-plate 100, can realize adjustment to front end-plate 100 evenness by the evenness of regulating evenness adjustable plate 101.Tightness adjustment by different adjustment screws can realize the adjustment to the evenness of evenness adjustable plate 101.Can determine a plane due to 3, therefore preferably, evenness adjustable plate 101 is adjusted screws by at least three and is fixed.For example as shown in Figure 2, in the two ends of evenness adjustable plate 101, one end has one and adjusts screw (screw 115), the other end has two and adjusts screw, when adjusting, method of adjustment only has an end of adjusting screw motionless for keeping more fast, and realizes leveling by two adjustment screws adjusting the other end.
According to the planform of evenness adjustable plate 101 and center adjustment plate 102, as shown in Figure 2, evenness adjustable plate 101 comprises three three the first double-screw bolts 111 that are arranged at its edge, and center adjustment plate 102 comprises four the second double-screw bolts 121.The position of the second double-screw bolt 121 is corresponding to the edge of front end-plate 100.And because the second double-screw bolt 121 is set to pass front end-plate 100, therefore the first double-screw bolt 111 is arranged at the outside of the second double-screw bolt 121, and does not contact with front end-plate 100.
Preferably, have a plurality of springs 123 between center adjustment plate 102 and front end-plate 100, each spring 123 is sheathed on second double-screw bolt 121, and the two ends of each spring 123 are respectively against front end-plate 100 and center adjustment plate 102.
When by adjusting device of the present utility model, front end-plate 100 being carried out the adjusting at evenness and center, at first need to regulate evenness adjustable plate 101 by laser collimator and carry out the calibration of evenness.When evenness need to be adjusted, adjust screws and realize evenness adjustment to front end-plate 100 by regulating at least three of evenness adjustable plate 101.For example as shown in Figure 2, in the two ends of evenness adjustable plate 101, one end has one and adjusts screw (screw 115), the other end has two and adjusts screw, when adjusting, method of adjustment only has an end of adjusting screw motionless for keeping more fast, and realizes leveling by two adjustment screws adjusting the other end.
After evenness is adjusted, then regulate center adjustment plate 102 by the center adjustment instrument and carry out the calibration at center.When the center need to be adjusted, can unclamp the fastener 112 that coordinates with the first double-screw bolt 111, then the position of horizontal adjustment center adjustment plate 102, when center adjustable plate 102 drives front end-plates 100 and moves to the precalculated position, more fixedly fastener 112 is realized the adjustment at center.Although be arranged so that evenness adjustable plate 101 and the center adjustment plate 102 of the first double-screw bolt 111 and the second double-screw bolt 121 are connected to each other, form two and separated independently mechanism, be independent of each other.In addition, in the present embodiment, center adjustment plate 102 is positioned at the below of front end-plate 100, further comprise a plurality of springs 123 for supporting front end-plate 100 between center adjustment plate 102 and front end-plate 100, when regulating the center of front end-plate 100 by center adjustment plate 102, spring 123 plays the function that supports the front end-plate horizontal direction, makes in the process at the center of adjusting substantially can not exert an influence to evenness, thereby has avoided the adjusting complexity that increases owing to influencing each other.
Preferably, evenness adjustable plate 101 surfaces have the location hole 113 for the relative position of definite and protecgulum.In the situation that location hole 113 can be aimed at, can omit the step at adjusting center.Because location hole 113 is predefined assembling and positioning mechanism, therefore can improve production, installation effectiveness.
As seen from the above technical solution, adopt the utility model can produce following beneficial effect:
1, video camera front end-plate adjusting device of the present utility model, the evenness governor motion of front end-plate and center adjustment mechanism are integrated, make the center that to regulate within the specific limits front end-plate after the evenness of regulating front end-plate, thereby eliminate the black surround phenomenon, simplify regulating step.
2, the evenness governor motion of video camera front end-plate adjusting device of the present utility model and center adjustment mechanism are two separately parts independently, are independent of each other.Carry out again can not affecting the adjusting result of evenness in the process of center adjustment after regulating evenness.
3, the adjustable video camera regulating mechanism of front end-plate of the present utility model is simple in structure, easy to assembly, can reduce and make and maintenance cost.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of the utility model protection.
