Description

Technical Field

[0001] The utility model relates to the technical field of dissolution test, in particular to a camera device for observing dissolution test phenomena. Background Art

[0002] Dissolution test is an important test for evaluating the intrinsic quality attributes of oral solid preparations. Observing and recording the phenomena of the entire test process of the test product during the test has important traceability guidance significance for analyzing the dissolution results of the test product. The existing camera method usually uses a water tank external camera, which is divided into several different viewing angles of the dissolution cup, such as looking down, looking up, and looking straight.

[0003] The disadvantages of existing observation methods are:

[0004] 1. The camera is external and needs to be refracted by three different media: a constant temperature water bath, water, and a dissolution cup. Different media cause different refractive indices, which may cause distortion in the observed phenomenon.

[0005] 2. No matter which viewing angle is used, the test phenomenon of the dissolution cup in the center of the back row cannot be observed from a straight-on perspective. Utility Model Content

[0006] The purpose of the utility model is to provide a camera device for observing dissolution test phenomena, so that the device structure is simple, easy to disassemble and assemble, and the modular design combination is more flexible. The high-definition wide-angle underwater camera adopts a large wide-angle underwater camera to reduce the observation distortion caused by the change of refractive index of different media. The independently designed camera bracket can adjust the angle at will, and cooperate with the focusing function of the camera to achieve the clearest observation angle, and can also solve the problem that the prior art cannot observe the phenomenon in the middle dissolution cup in the back row from a front view.

[0007] To achieve the above-mentioned purpose, a camera device for observing dissolution test phenomena is provided, comprising: a U-shaped frame, an adjustment plate is arranged below the U-shaped frame, a rotating pin is fixedly connected to the U-shaped frame, the circumferential surface of the rotating pin is rotatably connected to the adjustment plate, a fixing ring is threadedly connected to the circumferential surface of the rotating pin, an elastic clip is fixedly connected to the adjustment plate, and a high-definition wide-angle underwater camera is clamped on the elastic clip.

[0008] According to the camera device for observing dissolution test phenomena, the number of the adjustment plate, the rotating pin, the fixing ring, the elastic clip and the high-definition wide-angle underwater camera is two, and they are symmetrically distributed below the U-shaped frame.

[0009] According to the camera device for observing dissolution test phenomena, the elastic clip is made of elastic soft plastic material.

[0010] According to the camera device for observing dissolution test phenomena, wire grooves are provided on the top and left and right side walls of the U-shaped frame.

[0011] According to the camera device for observing dissolution test phenomena, the high-definition wide-angle underwater camera is externally connected to a large-capacity hard disk video camera and a display.

[0012] According to the camera device for observing dissolution test phenomena, the high-definition wide-angle underwater camera adopts a 220° wide-angle underwater high-definition camera and has a built-in focusing function.

[0013] The above scheme has the beneficial effects: by setting a U-shaped frame, an adjustment plate, a rotating pin, a fixing ring, an elastic clip and a high-definition wide-angle underwater camera, the device structure is simple, easy to disassemble and assemble, and the modular design combination is more flexible. The high-definition wide-angle underwater camera adopts a large wide-angle underwater camera to reduce the observation distortion caused by the change of refractive index of different media. The independently designed camera bracket can adjust the angle at will, and cooperate with the focusing function of the camera to achieve the clearest observation angle. It can also solve the problem that the existing technology cannot observe the phenomenon in the middle dissolution cup in the back row from a front view.

[0023] There are two adjustment plates 2 , rotating pins 3 , fixing rings 4 , elastic clips 5 and high-definition wide-angle underwater cameras 6 , which are symmetrically distributed below the U-shaped frame 1 .

[0024] Working principle: The high-definition wide-angle underwater camera 6 can be directly immersed in the water bath to observe the test phenomena in the dissolution cup. After focusing, the high-definition wide-angle underwater camera 6 is clamped with the elastic clip 5 to ensure that it is clamped tightly without loosening. The elastic clip 5 is fixed on the adjustment plate 2. The adjustment plate 2 and the U-shaped frame 1 are movably connected through the rotating pin 3 to ensure that the adjustment plate 2 can freely rotate at an angle of 180° through the rotating pin 3 to realize a group of camera modularization. Two high-definition wide-angle underwater cameras 6 are installed in the positive direction on a group of camera modules. Each high-definition wide-angle underwater camera 6 can observe the test phenomena in two opposite dissolution cups at the same time. Therefore, a group of camera modules can observe the test phenomena in four dissolution cups at the same time. The angle adjustment of the adjustment plate 2 is combined with the automatic focusing of the high-definition wide-angle underwater camera 6 to achieve the clearest observation angle. The high-definition wide-angle underwater camera 6 is externally connected to a large-capacity hard disk camcorder and a display to observe and record the test phenomena in the dissolution cup in real time.
