Description

Technical Field

[0001] This utility model belongs to the field of fixture technology, specifically relating to a fixture for shooting equipment. Background Technology

[0002] Optical microscopes are ubiquitous in life science experiments worldwide, including in China, where they are found in universities, research institutes, and even primary and secondary schools. More advanced optical microscopes can now be connected to computers, allowing operators to observe and save images in real time. However, most optical microscopes still exist as standalone instruments, with operators directly observing slides through the eyepiece and taking photos (often using a mobile phone).

[0003] There are still many inconveniences of an independent optical microscope: (1) When operating an optical microscope, the operator has to look for the image with their eyes, which usually takes 5 to 10 seconds. This is because the image presented by the eyepiece can only be seen by the eye in a specific and appropriate position (it is not like a telescope where you can see it clearly by bringing your eyes close to it). Some operators even have long eyelashes, which may touch the eyepiece and affect the experience of the observation results.

[0004] (2) When observing the results that you want to save, most independent optical microscopes only allow the operator to take pictures with their mobile phone to record them. The image produced by the eyepiece must be 2-3 cm above the eyepiece. It is not enough to just put the camera in front of the eyepiece (you often can't take any pictures). Therefore, one hand is usually held against the eyepiece and the other hand is used to take pictures. If the hand moves slightly or the lens deviates slightly, the appropriate area for taking pictures will be missed. Moreover, the results are often not very good. Either the whole area is not captured or the field of view is not filled. Therefore, it is necessary to repeatedly operate to take pictures, which seriously affects the efficiency of the experiment. Utility Model Content

[0005] To address the problems of high operational difficulty and cumbersome operation when taking images using an independent optical microscope in existing technologies, this utility model provides a camera fixation device.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A camera mounting device includes a first mounting frame, a mounting block slidably connected to the first mounting frame via a first sliding mechanism, and a camera mounting bracket slidably connected to the mounting block via a second sliding mechanism. The sliding directions of the first and second sliding mechanisms are perpendicular to each other. The first mounting frame is connected to a second mounting frame via a first telescopic mechanism, and the second mounting frame is connected to a fixing mechanism for fixing the device to an optical microscope via a second telescopic mechanism. The fixing mechanism is rotatably connected to the second telescopic mechanism, and the first mounting frame is rotatably connected to the first telescopic mechanism.

[0008] By adopting this technical solution, shooting devices, such as mobile phones, can be installed on the shooting device mounting frame. Then, the fixture is installed on the optical microscope through the fixing mechanism. The position of the camera is coarsely adjusted through the second telescopic mechanism and the shooting device can be moved on the first fixing frame through the first sliding mechanism and the second sliding mechanism to finely adjust the position of the camera. This achieves the technical effect of accurately adjusting the position of the shooting device, greatly reducing the shooting difficulty and making the operation simple and convenient.

[0009] Preferably, both the first telescopic mechanism and the second telescopic mechanism are rotatably connected to the second fixed frame, and the second telescopic mechanism is rotatably connected to the fixed mechanism.

[0010] After adopting this technical solution, both the first telescopic mechanism and the second telescopic mechanism are rotatably connected to the second fixed frame. The rotatable connection between the second telescopic mechanism and the fixed frame makes the position adjustment effect better. When not in use, the first fixed frame can be rotated away from the vicinity of the eyepiece.

[0011] Preferably, the first fixing frame is a hollow rectangular frame, the first sliding mechanism includes a first screw rotatably connected to the first fixing frame, a first sleeve threadedly connected to the first screw, the first sleeve being fixedly connected to the fixing block, a first limiting groove provided on the first fixing frame and arranged parallel to the screw, and a first limiting block provided on the fixing block and cooperating with the first limiting groove.

[0012] With this technical solution, the first fixing frame is a hollow rectangular frame that is large enough to allow the camera to protrude, thus preventing the acquisition of corresponding images. By rotating the first screw, the first sleeve can be moved on the first fixing frame to achieve fine adjustment of the position of the shooting device.

[0013] Preferably, the fixed block is provided with a movable groove, a second screw is rotatably connected in the movable groove, a second sleeve is threadedly connected to the second screw, a second limiting groove is provided in the movable groove parallel to the second screw, a second limiting block is provided on the second sleeve that cooperates with the second limiting groove, and the shooting equipment mounting bracket is fixedly connected to the second sleeve.

[0014] By adopting this technical solution, the second sleeve can be moved on the first fixed frame by rotating the second screw, so as to achieve fine adjustment of the position of the shooting equipment.

[0015] Preferably, the shooting equipment mounting bracket includes two parallel spring telescopic rods, with the same end of the two spring telescopic rods connected by an inverted L-shaped limiting bracket, and the two inverted L-shaped limiting brackets are symmetrically arranged.

[0016] After adopting this technical solution, the L-shaped limiting frame and the spring telescopic rod can be used to make the inverted L-shaped limiting frame abut against both sides of the shooting equipment, thereby fixing the shooting equipment.

[0017] Preferably, the inner surfaces of both inverted L-shaped limiting frames are provided with silicone pads.

[0018] By adopting this technical solution, the friction between the shooting equipment mounting bracket and the shooting equipment can be increased through the silicone pad, thereby increasing the stability of the connection.

[0019] Preferably, the fixing mechanism includes an open ring, and an inclined first clamping plate and a second clamping plate are provided at the opening of the open ring. The side of the first clamping plate and the second clamping plate away from each other is an arc surface, and the arc surface is provided with external threads. The first clamping plate and the second clamping plate are detachably connected by a fixing ring with internal threads.

[0020] With this technical solution, the open ring can be snapped onto the eyepiece through the opening of the open ring, and then the fixing ring is sleeved on the first clamping plate and the second clamping plate. Rotating the fixing ring can connect the first clamping plate and the second clamping plate, thereby fixing the device onto the eyepiece.

[0021] Preferably, both the first telescopic mechanism and the second telescopic mechanism include an outer rod, one end of which is provided with a sliding groove, and an inner rod is slidably connected in the sliding groove. The outer rod is provided with a fixing hole communicating with the sliding groove, and a tightening bolt that cooperates with the inner rod is threaded into the fixing hole.

[0022] With this technical solution, the inner rod can be tightened into the sliding groove by the tightening bolts, thus fixing the length of the telescopic mechanism. When the length needs to be adjusted, the tightening bolts can be loosened.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0024] 1. This utility model allows for the installation of shooting devices, such as mobile phones, onto a shooting device mounting frame. Then, a fixing mechanism is used to install the fixture onto an optical microscope. The position of the camera is coarsely adjusted using a second telescopic mechanism and finely adjusted using a first sliding mechanism and a second sliding mechanism, allowing the shooting device to move on a first fixing frame. This achieves the technical effect of precisely adjusting the position of the shooting device, greatly reducing the difficulty of shooting and making the operation simple and convenient.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] The following is combined Figure 1 This utility model will be described in detail.

[0031] A camera mounting device includes a first mounting frame 1, a mounting block 2 slidably connected to the first mounting frame 1 via a first sliding mechanism, and a camera mounting bracket slidably connected to the mounting block 2 via a second sliding mechanism. The sliding directions of the first sliding mechanism and the second sliding mechanism are perpendicular to each other. The first mounting frame 1 is connected to a second mounting frame 11 via a first telescopic mechanism 10. The second mounting frame 11 is connected to a fixing mechanism for fixing the device to an optical microscope via a second telescopic mechanism 12. The fixing mechanism is rotatably connected to the second telescopic mechanism, and the first mounting frame 1 is rotatably connected to the first telescopic mechanism 10.

[0032] In this embodiment, the first telescopic mechanism 10 and the second telescopic mechanism 12 are both rotatably connected to the second fixed frame 11, and the second telescopic mechanism 12 is rotatably connected to the fixed mechanism.

[0033] In this embodiment, as Figure 1 As shown, the first fixing frame 1 is a hollow rectangular frame, and the first sliding mechanism includes a first screw 8 rotatably connected to the first fixing frame 1. A first sleeve 9 is threadedly connected to the first screw 8. The first sleeve 9 is fixedly connected to the fixing block 2. A first limiting groove is provided on the first fixing frame 1 and parallel to the screw. A first limiting block is provided on the fixing block 2 and cooperates with the first limiting groove.

[0034] In this embodiment, refer to Figure 1 The second mounting bracket 11 is a rectangular frame structure composed of four round rods. The first telescopic mechanism 10 and the second telescopic mechanism 12 are rotatably connected to opposite sides of the rectangular frame structure. Specifically, each end of the first telescopic mechanism 10 and the second telescopic mechanism 12 is provided with a connecting sleeve, which is fitted onto the two opposite round rods of the rectangular frame structure. The connecting sleeve is in frictional contact with the round rod, and the friction between the connecting sleeve and the round rod is sufficient to ensure that the connecting sleeve will not rotate freely on the round rod after the mobile phone is connected to the shooting device mounting bracket. Similarly, the structure of the rotatable connection between the fixing mechanism and the second telescopic mechanism, and the rotatable connection between the first mounting bracket 1 and the first telescopic mechanism 10, is the same as the above-mentioned rotatable connection mechanism, and the friction at the rotatable connection can also ensure that the shooting device will not rotate freely after it is installed.

[0035] In this embodiment, the fixed block 2 is provided with a movable groove 3, and a second screw 4 is rotatably connected within the movable groove 3. A second sleeve 5 is threadedly connected to the second screw 4. A second limiting groove is provided within the movable groove 3, parallel to the second screw 4. A second limiting block is provided on the second sleeve 5, cooperating with the second limiting groove. The shooting device mounting bracket is fixedly connected to the second sleeve 5. The cooperation of the second limiting block and the second limiting groove ensures that the second sleeve 5 can only move along the second screw 4 and will not rotate with the second screw 4.

[0036] In this embodiment, the shooting equipment mounting bracket includes two parallel spring telescopic rods 7, with the same end of the two spring telescopic rods 7 connected by an inverted L-shaped limiting bracket 6, and the two inverted L-shaped limiting brackets 6 are symmetrically arranged.

[0037] In this embodiment, silicone pads are provided on the inner surfaces of both inverted L-shaped limiting frames 6. These silicone pads increase the stability of the connection between the shooting device and the inverted L-shaped limiting frames 6, and also protect the shooting device from wear and tear by the rigid inverted L-shaped limiting frames 6. The structure of the spring telescopic rod 7 is the same as existing spring telescopic structures; specifically, a spring is installed between two relatively sliding telescopic rods. When one of the telescopic rods slides out under external force, the spring applies a return-to-position pulling force, thereby achieving the effect of abutting the inverted L-shaped limiting frames 6 against both sides of the shooting device.

[0038] In this embodiment, the height of the spring telescopic column is 0.5cm, the height of the first fixing frame 1 is 1cm, and the thickness of the fixing block is 1 side. Therefore, when in use, placing the bottom surface of the first fixing frame 1 on the same horizontal plane as the eyepiece surface can ensure that the distance between the camera and the eyepiece is between 2-3cm.

[0039] In this embodiment, as Figure 1As shown, the fixing mechanism includes an open ring 13. An inclined first clamping plate 14 and a second clamping plate 15 are provided at the opening of the open ring 13. The side of the first clamping plate 14 and the second clamping plate 15 away from each other is an arc surface with external threads. The first clamping plate 14 and the second clamping plate 15 are detachably connected by a fixing ring with internal threads. The open ring 13 is made of a plastic material with a certain degree of flexibility. When the first clamping plate 14 and the second clamping plate 15 are not connected, the annular structure of the open ring 13 is slightly larger than the size of the eyepiece, allowing the eyepiece to be easily inserted into the open ring 13. Then, the first clamping plate 14 and the second clamping plate 15 are connected by the fixing ring (not shown in the figure, which is a circular ring with internal threads and made of plastic), causing the inner wall of the open ring 13 to abut against the outer wall of the eyepiece, increasing the friction between the open ring and the eyepiece, thereby fixing the device to the eyepiece. The curvature of the arc surfaces of the first clamping plate 14 and the second clamping plate 15 matches the size of the ring, so that the ring can rotate smoothly on the first clamping plate 14 and the second clamping plate 15.

[0040] In this embodiment, both the first telescopic mechanism 10 and the second telescopic mechanism 12 include an outer rod. One end of the outer rod is provided with a sliding groove, and an inner rod is slidably connected within the sliding groove. The outer rod is provided with a fixing hole communicating with the sliding groove, and a tightening bolt that mates with the inner rod is threaded into the fixing hole. By rotating the tightening bolt, the inner rod can be locked or unlocked to ensure that the lengths of the first telescopic mechanism 10 and the second telescopic mechanism 12 are fixed.

[0041] The specific method of using this utility model is as follows:

[0042] Reference Figure 1 When using the camera holder, first attach the opening ring 13 to the eyepiece, then place the fixing ring on the first clamping plate 14 and the second clamping plate 15. Rotate the fixing ring to connect the first clamping plate 14 and the second clamping plate 15, thereby fixing the holder to the eyepiece. Then, insert the camera (in this embodiment, a mobile phone) into the gap between the two inverted L-shaped limiting frames 6. Fix the camera between the two inverted L-shaped limiting frames 6 by the restoring force of the spring telescopic rod. By rotating each rotating connection and adjusting the length of the first telescopic mechanism 10 and the second telescopic mechanism 12, the camera of the camera is roughly aligned with the eyepiece, so that the lower surface of the first fixing frame 1 is on the same horizontal plane as the surface of the eyepiece, thereby making the distance between the camera and the eyepiece 2-3cm. Then, by rotating the first screw 8 and / or the second screw 3, fine-tune the position of the camera until the desired image is observed on the camera, and then image acquisition can be performed.

[0043] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
