Description

Technical Field

[0001] The utility model belongs to the field of test equipment, and in particular relates to an auxiliary device for photographing EP tubes. Background Art

[0002] Prior art Chinese utility model patent CN209791614U provides an auxiliary device for photographing experimental phenomena in a centrifuge tube, which can adjust the height of the centrifuge tube during photography. However, this solution, due to the lack of a background at the back, results in variable background colors during photography, adversely affecting the analysis of the captured results. Furthermore, because the device securing the centrifuge tube is a rigid rod, the tube is prone to rocking when placed on it.

[0003] The prior art Chinese utility model patent CN208569270U provides a background device that facilitates the photography of centrifuge tubes. However, since the device integrates background plates of different colors on the device, the background colors of the entire device can only be a few pre-set ones. If other colors are required, they need to be newly prepared, which is relatively complicated. In addition, the solution only provides hooks of several fixed heights for hanging centrifuge tubes, and the height options for centrifuge tube photography are relatively limited.

[0004] Therefore, there is an urgent need for an auxiliary device that can securely fix the centrifuge tube and flexibly adjust the height of the centrifuge tube and the background color during shooting. Utility Model Content

In this embodiment, the plurality of supporting holes 22 are arranged in a row along the length direction of the plate body 21.

[0038] Figure 3 It is a three-dimensional sectional view of the clamping member in the embodiment of the present utility model.

[0039] As Figures 1 to 3 shown, the number of clamping members 23 is 2, which are arranged at both ends of the plate body 21 in the length direction, and include a fixing block 231, a clamping block 232 and a spring 233.

[0040] The fixing block 231 is a horizontally placed three-dimensional "I" - shaped structure, arranged at both ends of the plate body 21 in the length direction. A connecting channel 3 is vertically penetrated through the fixing block 231 along the vertical direction of the "I" - shaped structure.

[0041] The clamping block 232 includes a main body 2321, clamping teeth 2322 and an insertion groove 2323.

[0049] like Figures 1 to 5 As shown, the background snap-in plate 30 includes a back plate 31 and a snap-in plate 32 .

[0050] The back plate 31 is disposed at the rear of the upper portion of the bottom plate 11 and is connected to the left partition plate 12 and the right partition plate 13 to close the rear gap of the three-dimensional "concave"-shaped plate structure of the shooting frame 10.

[0051] Figure 6 yes Figure 4 Enlarged view of point C in the middle.

[0052] like Figures 1 to 6 As shown, the snap-in plates 32 are two vertically long strip-shaped plate structures. The two snap-in plates 32 are respectively connected to the left partition 12 and the right partition 13, and are both parallel to the back plate 31 and form a gap 4. The two gaps 4 are used to cooperate with each other to snap and fix cards of different colors at the same time. When in use, the required specific color card is placed in front of the side closest to the plate body 21 to use it as a background.

[0055] The number of the background lights 50 is several and they are evenly arranged in a row at the upper rear of the base plate 11, so as to highlight the cards of different colors fixed on the background card plate 30. The background lights 50 in this embodiment are powered by an external power supply or a battery inside the device.

[0056] In this embodiment, the material of any one or more components of the auxiliary device 100 for EP tube photography can be selected as a transparent material according to actual needs to assist the photography process.

[0057] The use process of the auxiliary device 100 for EP tube photography:

[0058] S01, open the top cover 40, insert a plurality of EP tubes into the supporting holes 22, and expose the lower ends of the EP tubes;

[0059] S02, cover the top cover 40;

[0060] S03, grasp the handle 24 and pull it upward or downward with force, so that the two engaging blocks 232 are subjected to a horizontal inward force through the engaging teeth 2322, thereby causing displacement and sliding into different engaging grooves 2; after falling into different engaging grooves 2, due to the elastic deformation of the spring 233 connected between the two engaging blocks 232, the two engaging blocks 232 are fixed and matched again and pushed into the displaced engaging grooves 2, ultimately causing the vertical height of the plate body 21 in the photographing frame 10 to change, and ultimately causing the height position of the EP tube engaged in the supporting hole 22 to change;

[0061] S04, selecting a specific color from the cards stuck in the two gaps 4, placing it in the foreground as the background, and then turning on the background light 50 to illuminate the cards;

[0062] S05, start shooting, change cards of different colors or end shooting.

[0063] Functions and Effects of the Embodiments

[0064] According to this embodiment, an auxiliary device for EP tube photography is provided, which includes: a shooting frame, which is a three-dimensional "concave"-shaped plate structure; a supporting plate, which is a long plate structure horizontally arranged in the shooting frame, used for clamping the EP tube and exposing the lower end of the EP tube to facilitate observation and shooting, and the supporting plate can be moved up and down in the shooting frame; a background clamping plate, which is arranged at the rear of the shooting frame, used for clamping cards of different colors and making the side of the card facing the supporting plate at least partially exposed.

[0065] Therefore, the auxiliary device for EP tube photography in this embodiment can securely fix the EP tube and flexibly adjust the height of the EP tube and the background color during photography.

[0066] Furthermore, the photographing stand includes: a base plate, which is a horizontally arranged plate-like structure; a left partition and a right partition, which are respectively arranged parallel to each other on both sides of the upper portion of the base plate and perpendicular to the plane of the base plate; and two sliding grooves, which are respectively horizontally penetrated through the left partition and the right partition, and the two sliding grooves are mirror-symmetrical and have a vertical length direction. The supporting plate includes: a plate body, which is a horizontally arranged long strip of plate-like structure, the length direction of the plate body being perpendicular to the plane of the left partition and / or the right partition; a supporting hole, which is vertically penetrated through the plate body and is used to clamp and fix the upper end of the EP tube so that the lower end is exposed; two clamping parts, which are arranged at both ends of the plate body in the length direction and match the sliding grooves to be movably clamped and fixed, and the supporting plate can be clamped and fixed in the two sliding grooves by the clamping parts. This arrangement allows the upper and lower positions of the EP tube to be photographed to be quickly adjusted.

[0067] Furthermore, the sliding slot is provided with a plurality of serrated protrusions along its length, with engaging grooves formed between each pair of these serrated protrusions. The engaging members include: a fixed block provided on the plate body; and two engaging blocks, which engage with the engaging grooves and are movably provided at both ends of the fixed block, with their movable direction being horizontal and perpendicular to the length of the plate body.
