Background

A camera is a device that typically captures still images or real-time video using an optical sensor and lens. They are commonly found in various applications in electronic devices, computers, smart phones, monitoring systems, and the like. The main function of the camera is to convert a scene into an electric signal through an optical technology, and convert the electric signal into a digital image or video format for display, recording and transmission. The working principle of the camera is to focus light rays by using a lens, and then convert the light rays into electric signals by using an optical sensor (such as CMOS or CCD).

The parameters of the camera can be different according to specific models and manufacturers, common camera parameters comprise resolution, frame rate, aperture value, sensitivity and the like, and in reality, detection of the performance parameters of the camera exists to screen out qualified cameras. In the detection process, the cameras are small in size and different in specification, so that the cameras are difficult to fix.

Disclosure of Invention

Preferably, the driving assembly comprises a threaded screw rod and a second mounting seat, one end of the threaded screw rod is rotatably mounted on the first mounting seat, the other end of the threaded screw rod is rotatably mounted on the second mounting seat, the end part of the threaded screw rod is connected with a first manual adjusting piece, the movable seat is coaxially arranged between the second mounting seat and the first mounting seat, and the movable seat is in threaded fit with the threaded screw rod.

Preferably, the driving assembly comprises at least one guide rod, wherein the guide rod penetrates through the movable seat, and two ends of the guide rod are fixed on the second installation seat and the first installation seat.

Preferably, the first manual adjusting members each include a hand twisting block.

Preferably, the annular groove comprises a proximal groove suitable for clamping the camera lens and a distal groove suitable for clamping the camera lens base, and the proximal groove and the distal groove form steps.

The present utility model provides a detection system, such as a resolution detection system, for detecting a camera, the detection system comprising a fixture as described above.

According to the camera fixing device, the clamping of cameras of different specifications is guaranteed by means of the variable inner diameter of the semicircular fixing annular groove of the clamping jaw, and due to the fact that the size of the camera is small, the difficulty in fixing the camera is large, damage to a lens of the camera is easily caused, the camera clamping mechanism solves the technical problems that the camera is too small to position and inaccurate in positioning through the openable annular groove, the applicability of camera positioning and clamping is greatly improved, and the positioning and clamping accuracy of the camera is improved.

Detailed Description

The utility model or the technical scheme of the utility model is further specifically described below through specific embodiments and with reference to the accompanying drawings;

in the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "front", "rear", "left", "right", "upper", "lower", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model. The term "plurality" refers to two or more.

In the description of the present utility model, it should be noted that, unless otherwise specified and defined, the terms "mounted" and "connected" are to be construed broadly, and may be, for example, mechanical or electrical, or may be internal to two elements in communication, or may be directly or indirectly connected through an intermediate medium, and the specific meaning of the terms may be understood by those skilled in the art according to circumstances.

Example 1

Referring to fig. 1, the embodiment of the utility model provides a fixing device for detecting a camera, the fixing device includes a left fixing member, a right fixing member and a driving assembly for driving the left fixing member and the right fixing member to approach or depart from each other, the left fixing member includes a first mounting seat 21 and a left plate 22 connected to the first mounting seat 21, the second clamping member includes a moving seat 31 and a right plate 32 connected to the moving seat 31, the first mounting seat 21 and the moving seat 31 are coaxially arranged, the left plate 22 and the right plate 32 extend upwards compared with the connecting plate 13, the left plate 22 defines a left half ring 221, the right plate 32 defines a right half ring 321 arranged opposite to the left half ring 221, the driving assembly drives the right half ring 321 and the left half ring 221 to be close to each other to form an annular groove 300 for clamping the camera, the camera with different specifications, and the variable inner diameter of the annular groove 300 ensures the clamping of the camera.

Because the camera has the characteristics that the precision is high and the price is expensive, camera fixing device's fixed process needs slow and meticulous, and too quick adjustment arouses the circumstances that the camera breaks and the centre gripping is unstable easily, based on this, drive assembly includes screw 25 and second mount pad 26, screw 25 one end is rotated and is installed on first mount pad 21, the other end is rotatably installed on second mount pad 26 and end connection has first manual regulating part 27, remove seat 31 coaxial arrangement between second mount pad 26 and first mount pad 21, remove seat 31 and screw thread 25 screw-thread fit. Illustratively, the threaded rod 25 is rotatably fixed to the first mounting seat 21 and the second mounting seat 26 through bearings 29; in this way, the position of the moving seat 31 is slowly adjusted manually by the tester to approach the first mounting seat 21 toward the ideal position, and finally, the clamping and fixing of the camera are realized. This ring channel 300 has avoided the camera damage that current some supports caused through the whole parcel to the camera periphery to and because just fixed unstable phenomenon such as drop that arouses of camera that causes to the lens frame, the fixture that this embodiment provided is with the camera staple bolt in the ring channel completely, and the location is accurate and stable.

In this embodiment, the driving assembly includes at least one guide rod 28, where the guide rod 28 penetrates through the moving seat and two ends of the guide rod are fixed on the second mounting seat 26 and the first mounting seat 21.
