Technical Field

[0001] The utility model relates to the technical field of camera detection, in particular to a camera detection device. Background Art

[0002] After the camera is designed and processed, various functions need to be tested. One of the key tests is the anti-shake test. Currently, most camera anti-shake devices are usually installed on a vibration table for imaging testing.

[0003] Currently, Chinese patent publication number CN219478033U discloses a camera detection device. The device box is fixed to a base, and the vibration table is driven by a vibration motor inside the device box. Two vertical fixing rods are mounted on the vibration table, and a fixing plate is slidably mounted on the fixing rods. The fixing plate is provided with two horizontal transverse grooves and two vertical vertical grooves. The transverse and vertical grooves are T-shaped slots with narrow inner slot openings. The transverse and vertical slots are intersecting and connected. At least three inverted bolts are set in the transverse and vertical slots, and the nuts of the bolts are located in the transverse and vertical slots. This detection device is used to test the anti-shake function of the camera. It can use the vibration table for small amplitude testing. When large amplitude testing is required, the vibration motor is turned off, and the motor drives the eccentric wheel for large amplitude testing.

[0004] During actual use of the above-mentioned device, when detecting camera shake, the camera is tested for large amplitude by using an eccentric wheel and for small amplitude by using a vibration table. Therefore, two different testing methods are used, which increases the equipment cost. Moreover, when conducting the test, the adjustment amplitude of the device needs to be adjusted according to the installation of different eccentric wheels, which is more troublesome to use and affects the work efficiency of the detection.

[0007] In order to ensure stable movement of the moving rod, as a preferred camera detection device of the present invention, a limiting ring movably sleeved on the outer side walls of the two moving rods is fixedly installed on the left side wall of the fixed plate.

[0008] In order to ensure the stable movement of the moving block, as a preferred camera detection device of the present invention, sliding holes are opened on both symmetrical sides of the fixing frame, and the outer wall of the moving block is fixedly installed with a slide plate that is slidably connected to the two sliding holes respectively.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The present invention provides a camera that can be used for anti-shake detection by rotating the screw rod, thereby driving the sliding block to drive the sliding plate and the limit column to move toward the center of the turntable. At this time, by starting the motor, the turntable, the fixed frame, the moving block and the limit column can be driven to rotate, so that the limit column rotates to drive the sliding frame to swing slightly, thereby causing the sliding frame to drive the moving rod and the detection plate to move back and forth slightly up and down, which can detect the camera on the detection plate for anti-shake detection of a small amplitude. When the amplitude of the anti-shake detection needs to be increased, the position of the limit column can be adjusted by rotating the screw rod in the opposite direction to make it away from the center of the turntable. At this time, when the motor drives the turntable to rotate, the diameter of the limit column rotation becomes larger, which can drive the sliding frame to swing significantly, thereby causing the moving rod and the detection plate to move back and forth significantly up and down, thereby detecting the camera on the detection plate for anti-shake detection of a large amplitude. Further, the distance between the limit column and the center of the turntable can be adjusted by the screw rod, and the reciprocating path of the detection plate can be adjusted, thereby achieving the effect of facilitating the adjustment of the anti-shake detection amplitude, facilitating the camera to perform shake detection of different amplitudes, reducing costs, and effectively improving work efficiency.

Then, the distance between the limit column 7 and the center of the turntable 4 can be adjusted by the screw 5, and the reciprocating path of the detection plate 901 can be adjusted, so as to achieve the effect of facilitating the adjustment of the anti-shake detection amplitude, facilitating the camera to perform different amplitudes of shake detection, reducing costs, and effectively improving work efficiency.

[0021] As a technical optimization solution of the present invention, a limiting ring 302 movably sleeved on the outer side walls of the two moving rods 8 is fixedly installed on the left side wall of the fixed plate 3 .

[0022] In this embodiment, by providing the limiting rings 302 , when the two moving rods 8 move, they can move along the two limiting rings 302 respectively. The limiting rings 302 can limit the moving rods 8 , so that the moving rods 8 can move stably.

[0023] As a technical optimization solution of the present invention, sliding holes 402 are opened on both symmetrical sides of the fixed frame 401, and the outer wall of the moving block 501 is fixedly installed with a slide plate 502 that is slidably connected to the two sliding holes 402 respectively.

[0024] In this embodiment, by setting the slide plate 502, when the screw rod 5 pushes the moving block 501 to move, the moving block 501 can drive the two slide plates 502 to move along the two sliding holes 402. The sliding holes 402 can limit the moving direction of the slide plates 502, so that they can move stably.

[0027] As a technical optimization solution of the present invention, the limiting column 7 is in a "T" shape, and the size of the left end is larger than the size of the inner hole of the sliding frame 6.

[0028] In this embodiment, by setting the left end of the limiting post 7 to be larger than the size of the inner hole of the sliding frame 6 , the sliding frame 6 can be limited, so that the sliding frame 6 can move stably on the limiting post 7 .

[0031] Working principle: First, when using the device to perform an anti-shake test on a camera, first use bolts to install the camera to be tested on the detection plate 901, and adjust the amplitude of the anti-shake test as needed. The specific operation is that by rotating the screw 5, the moving block 501 can be pushed to drive the slide plate 502 to move along the slide hole 402 toward the center of the turntable 4, so that the slide plate 502 can stably drive the limit column 7 to move toward the center of the turntable 4. At this time, by starting the motor 301, the turntable 4, the fixed frame 401, the moving block 501 and the limit column 7 can be driven to rotate, so that the limit column 7 can rotate and drive the slide frame 6 The small swing makes the sliding frame 6 drive the moving rod 8 and the detection plate 901 to move back and forth slightly up and down, and the camera on the detection plate 901 can be subjected to a small anti-shake detection. When the amplitude of the anti-shake detection needs to be increased, the position of the limit column 7 can be adjusted by rotating the screw rod 5 in the opposite direction to move it away from the center of the turntable 4. At this time, when the motor 301 drives the turntable 4 to rotate, the diameter of the limit column 7 becomes larger, which can drive the sliding frame 6 to swing greatly, thereby making the moving rod 8 and the detection plate 901 move back and forth significantly up and down, and the camera on the detection plate 901 can be subjected to a large anti-shake detection.
