[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] like Figure 1-Figure 6 As shown, the present embodiment discloses an adjustable specimen upper rack, comprising a plurality of test tube racks 1, which are arranged in sequence at intervals, and two adjacent test tube racks 1 are connected by a horizontal telescopic mechanism 2; the side of one of the test tube racks 1 located at the edge is connected to a hanging plate 4 through a height adjustment mechanism 3; there are a plurality of mounting plates 5, which correspond to the test tube racks 1 one by one, and the test tube racks 1 are connected to the corresponding mounting plates 5; bases 6 are provided on both sides of the mounting plates 5, and the sides of the two bases 6 away from each other are fixedly connected with vertically arranged side plates 7, and the sides of the two bases 6 close to each other are provided with slide grooves 8, and the two ends of the mounting plate 5 are respectively extended into the corresponding slide grooves 8 and slidably connected thereto; the bottom surface of the mounting plate 5 is provided with a driving mechanism 9, and the driving mechanism 9 drives the two bases 6 to move in the opposite direction.

[0032] In this embodiment, the test tube rack 1 provided can be used to vertically place the test tubes containing specimens; the horizontal telescopic mechanism 2 provided can be used to adjust the distance between two adjacent test tube racks 1, so that the overall length of the present invention can be adjusted; the height adjustment mechanism 3 provided can be used to adjust the height of the hanging plate 4; the driving mechanism 9 provided drives the two bases 6 to move in the opposite direction, so that the distance between the two side plates 7 can be adjusted, so that the overall width of the present invention can be adjusted; through the coordinated use of the above-mentioned structures, the length, width and height of the hanging plate 4 of the present invention can be adjusted, so that the present invention can be adapted to a variety of different brands of testing instruments. When the same specimen is tested on different testing instruments, there is no need to replace the upper rack, thereby avoiding the occurrence of biosafety incidents such as specimen misplacement, overturning, and spillage caused by multiple replacements of the specimen and the upper rack, greatly reducing safety hazards.

[0033] Further optimization scheme, such as Figure 2 As shown, the test tube rack 1 includes two vertical plates 101 fixed to the top surface of the mounting plate 5 in parallel and at intervals, and the horizontal telescopic mechanism 2 and the height adjustment mechanism 3 are respectively connected to the vertical plates 101; a plurality of placement sleeves 102 for limiting the position of the test tubes are fixedly connected between the two vertical plates 101 along the height direction. The two vertical plates 101 are provided to achieve the effect of installing and fixing the plurality of placement sleeves 102; the plurality of placement sleeves 102 are provided to achieve the effect of vertically placing the test tubes containing the specimens.

[0034] It is worth noting that the side panel 7 is made of transparent material, and a barcode is attached to the outer wall of the test tube containing the specimen. When the test tube is placed in the placement sleeve 102, the bottom of the test tube is against the top surface of the mounting plate 5, and the peripheral side wall of the test tube is in contact with the inner wall of the placement sleeve 102, and the barcode and the placement sleeve 102 are staggered with each other, so that the detection instrument can scan the barcode on the outer wall of the test tube through the transparent side panel 7.

[0035] Further optimization scheme, such as Figure 2 As shown, a plurality of limiting plates 103 for limiting the side plates 7 are fixedly connected to both sides of the vertical plate 101 along the height direction.

[0036] With this solution, the minimum distance between the two side plates 7 is limited by the setting of the limiting plate 103, that is, the minimum width of the present invention is limited.

[0037] Further optimization scheme, such as Figure 2 , Figure 3As shown, the horizontal telescopic mechanism 2 includes a mounting sleeve 21 connected to one of the test tube racks 1, a plate body 22 is slidably connected in the mounting sleeve 21, and the end of the plate body 22 is connected to the other test tube rack 1; a limiting component 23 is provided on the mounting sleeve 21, and the mounting sleeve 21 and the plate body 22 are limited by the limiting component 23.

[0038] In this embodiment, the mounting sleeve 21 is fixedly connected to the top of the vertical plate 101 of one of the test tube racks 1 , and the end of the plate body 22 is fixedly connected to the vertical plate 101 of the adjacent test tube rack 1 .

[0039] By adopting this solution, the limiting assembly 23 is set to limit or release the fixing between the mounting sleeve 21 and the plate body 22, thereby achieving the effect of adjusting the distance between two adjacent test tube racks 1, and at the same time ensuring the stability of the distance between the two after adjustment.

[0040] Further optimization scheme, such as Figure 3 As shown, the limiting assembly 23 includes a cylinder 231 fixedly connected to the side wall of the mounting sleeve 21, a guide slide 232 is slidably connected in the cylinder 231, a limiting rod 233 is fixedly penetrated on the guide slide 232, one end of the limiting rod 233 slides through the cylinder 231 and is fixedly connected to an operating block 234, and the other end of the limiting rod 233 slides through the interior of the mounting sleeve 21 and is plugged into and matched with the plate body 22.

[0041] In this embodiment, the cylinder 231 and the limiting rod 233 are both arranged horizontally, and the limiting rod 233 can be plugged into and connected to the plate body 22 to limit the plate body 22 .

[0042] Further optimization scheme, such as Figure 3 As shown, a plurality of insertion holes 220 for inserting the limiting rod 233 are arranged at intervals on the plate body 22; one end of the limiting rod 233 away from the operating block 234 is set as an arc surface.

[0043] By adopting this solution, the distance between two adjacent test tube racks 1 can be adjusted in multiple levels by setting a plurality of insertion holes 220 ; and by setting the end face of the limiting rod 233 as an arc surface, it is convenient to insert the limiting rod 233 into the insertion hole 220 .

[0044] Further optimization scheme, such as Figure 3 As shown, a spring 235 is sleeved on the outer periphery of the limiting rod 233 , and the spring 235 is located on the side of the guide slide 232 close to the operating block 234 , and two ends of the spring 235 are respectively against the guide slide 232 and the cylinder 231 .

[0045] In this embodiment, when the spacing between two adjacent test tube racks 1 is adjusted, the operating block 234 is first pulled outward to drive the limit rod 233 and the guide slide 232 to move in a direction away from the socket 220 until the end of the limit rod 233 is disengaged from the socket 220; then the relative position between the plate body 22 and the mounting sleeve 21 is adjusted, and the other socket 220 is made to correspond to the limit rod 233. At this time, the spring 235 is in a compressed state. After the operating block 234 is slowly released, under the action of the rebound force of the spring 235, the limit rod 233 and the guide slide 232 move in the direction of the socket 220 until the end of the limit rod 233 is inserted into the socket 220, thereby completing the limit fixation between the plate body 22 and the mounting sleeve 21.

[0046] It should be noted that, in this embodiment, after the end of the limiting rod 233 is inserted into the insertion hole 220, the spring 235 is still in a compressed state, so that the plug-in effect between the two can be improved.

[0047] Further optimization scheme, such as Figure 4 As shown, the height adjustment mechanism 3 includes a threaded sleeve 31 arranged on the side of the test tube rack 1, and a vertically arranged long screw 32 is threadedly connected in the threaded sleeve 31. One end of the long screw 32 is rotatably connected to the hanging plate 4, and the other end is fixedly connected to a knob 33; a vertically arranged guide rod 34 is fixedly connected to the hanging plate 4, and the guide rod 34 is slidably connected to the slip ring 35, and the slip ring 35 is fixedly connected to the test tube rack 1.

[0048] In this embodiment, the threaded sleeve 31 is fixed to the side of the vertical plate 101, and there are two guide rods 34, which are respectively located on both sides of the long screw rod 32; each guide rod 34 is slidably connected in at least two slip rings 35, and the slip rings 35 are fixed to the side of the vertical plate 101.

[0049] With this solution, by rotating the knob 1 33 , the hanging plate 4 can be driven to move up and down in the vertical direction under the guidance of the guide rod 34 , thereby achieving the effect of adjusting the height of the hanging plate 4 .

[0050] Further optimization scheme, such as Figure 5 , Figure 6 As shown, the driving mechanism 9 includes two rotating shafts 91 arranged in parallel and spaced relationship between the two bases 6, and the rotating shafts 91 are rotatably connected to the mounting plate 5; a driving rod 92 is fixedly connected to the rotating shaft 91, and the driving rods 92 on the two rotating shafts 91 are arranged in an eight-shaped shape, and the ends of the driving rods 92 are against the corresponding bases 6; a tension spring 93 is arranged in the slide groove 8, and the two ends of the tension spring 93 are respectively fixedly connected to the groove wall of the slide groove 8 and the end face of the mounting plate 5; a knob 2 94 is arranged between the two bases 6, and the knob 2 94 drives the two rotating shafts 91 to rotate in opposite directions through a transmission assembly 95.

[0051] In this embodiment, the vertical cross-section of the base 6 is an L-shaped structure, the slide groove 8 is horizontally arranged at the top of the vertical section of the L-shaped base 6, and the driving rod 92 is abutted against the end of the horizontal section of the L-shaped base 6; a plurality of balls 10 are installed on the top surface of the horizontal section of the L-shaped base 6, and the top of the balls 10 is in rolling contact with the bottom surface of the mounting plate 5. Specifically, a plurality of mounting grooves corresponding to the balls 10 are arranged on the top surface of the horizontal section of the L-shaped base 6, and the balls 10 are rotatably installed in the corresponding mounting grooves.

[0052] When it is necessary to increase the distance between the two bases 6, the mounting plate 5 is kept stationary, and the knob 2 94 is turned. Under the action of the transmission assembly 95, the two rotating shafts 91 are driven to rotate in opposite directions, and the two rotating shafts 91 respectively drive the driving rods 92 thereon to move in directions away from each other, so that the two bases 6 can be driven by the driving rods 92 to move in directions away from each other; at the same time, the tension spring 93 is in a stretched state; when it is necessary to reduce the distance between the two bases 6, the mounting plate 5 is kept stationary, and the knob 2 94 is turned in the opposite direction, so that the driving rods 92 on the two rotating shafts 91 move in directions approaching each other, and under the action of the rebound force generated by the tension spring 93, the two bases 6 will move in a direction approaching each other.

[0053] It should be noted that, in this embodiment, when the side plate 7 abuts against the limiting plate 103 , that is, when the overall width of the present invention is at a minimum, the tension spring 93 is still in a stretched state.

[0054] Further optimization scheme, such as Figure 5 As shown, the transmission assembly 95 includes a worm 951 vertically arranged between two rotating shafts 91, the bottom surface of the worm 951 is fixedly connected to the middle of the top surface of the knob 2 94, and the top of the worm 951 is rotatably connected to the mounting plate 5; worm wheels 952 are fixedly mounted on the two rotating shafts 91, and the two worm wheels 952 are respectively meshed and connected with the worm 951.

[0055] In this embodiment, an L-shaped plate 953 is fixed to the bottom surface of the mounting plate 5, and the bottom of the worm 951 is rotatably connected to the horizontal section of the L-shaped plate 953. By providing the L-shaped plate 953, the stability of the worm 951 during rotation can be improved.

[0056] With this solution, by rotating the second knob 94 , the worm 951 is driven to rotate, and the worm 951 drives the two worm wheels 952 to rotate in opposite directions, thereby achieving the effect of driving the two rotating shafts 91 to rotate in opposite directions.

[0057] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
