The two vertical bars of the n-shaped frame 16 are respectively fixedly arranged on the upper ends of the left and right side walls of the box body 1. The n-shaped frame 16 is used to install the top cover 2 described later; A top cover 2 is slidably mounted on the top of the n-shaped frame 16. The top cover 2 is driven to slide by an opening and closing mechanism. The opening and closing mechanism is driven by the first sliding mechanism. The top cover 2 can be opened and closed under the drive of the opening and closing mechanism. The lower ends of the left and right side walls of the box body 1 are respectively slidably mounted with expansion storage boxes 11. The two expansion storage boxes 11 are driven to slide by the second sliding mechanism. The top cover 2 drives the two second sliding mechanisms to work by sliding. The expansion storage boxes 11 are used to place some flat-bottomed collection dishes and are stabilized by the rubber clamp ring described later. The expansion storage boxes 11 are driven by the second sliding mechanism to be unfolded when the device is unfolded. A refrigerator 21 is fixedly installed on the upper end of the bottom wall of the box body 1. The refrigerator 21 is a double-layer structure, divided into an inner box and an outer box.

[0022] The first sliding mechanism comprises an armrest 23 and a first connecting rod 9; The lower end of the crossbar of the n-shaped frame 16 is provided with first rectangular through slots 1602 on both sides near the end, and the first connecting rods 9 are slidably installed in the two first rectangular through slots 1602; An armrest 23 is fixedly installed between the first ends of the two first connecting rods 9; The armrest 23 slides on the outer side of the rear wall of the box body 1; The upper ends of the left and right side walls of the tool storage box 14 are fixedly connected to the lower ends of the two first connecting rods 9 respectively; A cross-shaped partition plate 1401 for isolating instruments is installed in the tool storage box 14, and its function is to separate and isolate multiple collection instruments. Medical staff can place the instruments to be used and the instruments already used in different partitions to distinguish them and avoid mixing them; The two first connecting rods 9 drive the lifting mechanism and the opening and closing mechanism respectively by sliding. The user holds the armrest 23 and pulls it outward. At this time, the two first connecting rods 9 will be pulled outward at the same time as the armrest 23, and at the same time, drive the tool storage box 14 fixedly connected thereto to be pulled outward. The cooperation between the first rectangular through groove 1602 and the first connecting rod 9 ensures the sliding trajectory of the first connecting rod 9 and ensures that it will not deviate and fall off during the sliding process.

[0023] The lifting mechanism comprises an I-shaped slider 19 and a second connecting rod 15; T-shaped slide grooves 102 are respectively provided in the left and right side walls of the box body 1 close to the refrigerator 21; The first horizontal plates of the I-shaped sliders 19 are slidably mounted in the two T-shaped slide grooves 102; The outer walls of the second horizontal plates of the two I-shaped slide blocks 19 are respectively provided with connecting shafts, and the two ends of the test tube rack 17 are respectively fixed between the two connecting shafts; The first ends of the second connecting rods 15 are rotatably mounted on the two connecting shafts, and the second ends of the two second connecting rods 15 are rotatably connected to the second ends of the two first connecting rods 9, respectively. Figure 2 When the two first connecting rods 9 slide to the right, the two second connecting rods 15 begin to deflect upward. During the upward deflection, the two second connecting rods 15 respectively drive the two I-shaped sliders 19 to slide upward along the T-shaped slide grooves 102 on both sides, and drive the test tube rack 17 to slide upward during the sliding process. When the two first connecting rods 9 slide to the left, the two second connecting rods 15 begin to deflect downward. At this time, the test tube rack 17 slides downward and drives the test tubes to be used into the refrigerator 21.

[0024] A plurality of expansion test tube racks 1701 are installed on the rear side of the test tube rack 17, and the plurality of expansion test tube racks 1701 are connected by first connecting columns, and the purpose is to expand the test tube rack 1701 for loading more test tubes; A plurality of extended test tube racks 1701 are movable above the refrigerator 21 .

[0025] The opening and closing mechanism comprises a third connecting rod 10, a T-shaped slider 18, a T-shaped slide rail 101, a fourth connecting rod 7, a rectangular slider 8, a rack plate 12, and a spur gear 13; Rectangular slide plates 201 are respectively installed at the lower ends of the left and right side walls of the top cover 2, and first rectangular slide grooves 1601 are respectively provided at the upper ends of the two vertical plates of the T-shaped frame 16, and the two rectangular slide plates 201 are respectively slidably arranged in the two first rectangular slide grooves 1601; The first ends of the two first connecting rods 9 are respectively rotatably mounted with the first ends of the third connecting rods 10 via the first rotating shafts; T-shaped slide rails 101 are respectively installed in the middle of the left and right side walls of the box body 1, and the horizontal plates of the T-shaped sliders 18 are slidably installed in the two T-shaped slide rails 101; Second connecting columns are respectively installed on the outer walls of the vertical rods of the two T-shaped sliders 18, and the second ends of the two third connecting rods 10 are respectively rotatably sleeved on the two second connecting columns; The first mounting plates 1801 are fixedly mounted at the ends of the two second connecting columns, respectively, and the third connecting rod 10 located on the same side is arranged between the T-shaped slider 18 and the first mounting plate 1801 located on the same side; Rack plates 12 are fixedly mounted on the front walls of the two first mounting plates 1801, respectively, and spur gears 13 are meshedly mounted on the other sides of the two rack plates 12; Two spur gears 13 are respectively arranged outside the left and right side walls of the box body 1 and are rotatable through the second rotating shaft; The first ends of the fourth connecting rods 7 are fixedly mounted at the ends of the two second rotating shafts, and the two fourth connecting rods 7 are respectively arranged on the outsides of the two spur gears 13; The two fourth connecting rods 7 are respectively provided with second rectangular through slots 701, and rectangular sliding blocks 8 are respectively slidably installed in the two second rectangular through slots 701; The middle of the left and right side walls of the top cover 2 are respectively fixedly mounted with third connecting columns, and the two third connecting columns are respectively rotatably connected to the inner walls of the two rectangular sliders 8; The two second rotating shafts respectively drive the two second sliding mechanisms to work by rotating. Figure 2When the user pulls the armrest 23 to slide to the right, the two first connecting rods 9 start to slide to the right. While sliding to the right, the two first connecting rods 9 pull the third connecting rods 10 on both sides to start to deflect upward. During the upward deflection, the third connecting rods 10 on both sides respectively drive the T-shaped sliders 18 on both sides to start to slide upward along the T-shaped slide rails 101 on both sides. During the upward sliding process, the two T-shaped sliders 18 respectively drive the first mounting plates 1801 to start to slide upward. During the upward sliding process, the two first mounting plates 1801 respectively drive the rack plates 12 on both sides to start to move upward. The rack plates 12 on both sides slide upwards and drive the spur gears 13 meshing therewith to start rotating. The spur gears 13 drive the fourth connecting rods 7 coaxially mounted therewith to start rotating downwards. During the downward rotation of the fourth connecting rods 7 on both sides, the rectangular sliding blocks 8 located in the two second rectangular through grooves 701 start to slide, and drive the top cover 2 to start sliding to the left during the sliding process. At this time, the interior of the box body 1 is completely exposed, and the test tube rack 17 located therein also rises upwards, so that medical staff can easily take out the test tubes to be used for use.

[0026] The second sliding mechanism comprises a fifth connecting rod 6, a rotating connecting block 5, a guide rod 4, a sliding rod 3, and a sixth connecting rod 20; The first ends of the fifth connecting rods 6 are respectively fixedly mounted on the two second rotating shafts, and the two fifth connecting rods 6 are respectively arranged perpendicularly to the two fourth connecting rods 7; The two fifth connecting rods 6 are respectively arranged on the inner sides of the two spur gears 13; The lower ends of the left and right side walls of the box body 1 are respectively provided with second rectangular slide grooves, and the two second rectangular slide grooves are respectively provided at the lower ends of the two T-shaped slide rails 101, and the slide bars 3 are respectively slidably installed in the two second rectangular slide grooves; The middle of the outer wall of the two slide bars 3 is respectively installed with a second mounting plate 301, and the upper ends of the two second mounting plates 301 are respectively vertically installed with a guide rod 4; The middle parts of the inner walls of the two fifth connecting rods 6 are respectively rotatably mounted with rotating connecting blocks 5, and the two guide rods 4 are respectively slidably penetrated with the two rotating connecting blocks 5; The rear ends of the two slide bars 3 are respectively rotatably mounted with the first ends of the sixth connecting rods 20, and the second ends of the two sixth connecting rods 20 are respectively rotatably connected to the lower ends of the front walls of the two expansion storage boxes 11, Figure 4When the fourth connecting rods 7 on both sides start to rotate counterclockwise, the fifth connecting rod 6 arranged perpendicular to the fourth connecting rods 7 on both sides also starts to rotate counterclockwise. During the counterclockwise rotation, the fifth connecting rod 6 on both sides respectively drives the rotating connecting blocks 5 rotatably connected thereto to also start to rotate counterclockwise. Since the two rotating connecting blocks 5 have a tendency to move from left to right during the counterclockwise rotation, the guide rod 4 slidingly penetrated by the two rotating connecting blocks 5 will slide to the right side under the drive of the two rotating connecting blocks 5, and the sliding rod 3 fixedly connected to the two guide rods 4 also starts to slide to the right side at this time. While sliding to the right, the two sliding rods 3 drive the sixth connecting rods 20 on both sides to start to deflect outward. During the outward rotation, the two second connecting rods 20 drive the expansion storage boxes 11 on both sides to extend from both sides of the box body 1.

[0027] The fifth connecting rod 6, the guide rod 4 and the slide rod 3 on the same side form a variable strap structure, refer to Figure 1 When the device is in the storage state, the fifth connecting rod 6 is exactly parallel to the extended sliding rod 3. At this time, the sliding rod 4 is exactly located between the front wall of the box body 1 and there is a gap. The medical staff can pass their arms through the gap to carry the device on their backs.

[0028] Several rubber clips for fixing tools are installed in the tool storage box 14 and the expansion storage box 11, the purpose of which is to ensure that the tools or utensils placed therein can be more stable.

[0029] Implementation method of the present invention: When the device is in the initial state, the top cover 2 is in a closed state, and the test tube rack 17 located in the box body 1 is at the bottom of the box body 1. The standby test tubes in the test tube rack 17 are in the refrigerator 21. The user can put the frozen ice cubes into the gap in the refrigerator 21 in advance so that the refrigerator 21 has a cooling effect for a certain period of time. The tool storage box 14 is in a state of being received into the box body 1 and is fixed to the box body 1 by a buckle. The tool storage box 14 contains instruments for collecting samples. The expansion storage box 11 is also in a state of being received into the box body 1. The flat-bottomed collection container is placed in it. When medical staff need to go out for a visit, they can pass their arms through the guide rods 4 on both sides to carry the device on their backs, and then they can move with the device.

[0030] After moving to the target area, the medical staff puts down the equipment, opens the buckle and pulls out the armrest 23 to the outside. At this time, the tool storage box 14 is pulled out, and the doctor can take out the collection tools inside. The top cover 2 at the top of the box body 1 is also opened at this time, and the test tube rack 17 inside is now raised from the cold storage box 21 with a number of test tubes to be used, so that the medical staff can take them at any time. The expansion storage boxes 11 on both sides of the box body 1 also begin to unfold as the top cover 2 is opened.

[0031] The medical staff puts the collected samples into the test tube rack or the expansion storage box 11 respectively, pushes the armrest 23 inward, and the equipment slowly stores them again. At this time, the fifth connecting rod 6, the guide rod 4, and the sliding rod 3 form a shoulder strap structure again, and the medical staff can carry it to the testing room for testing. Since there is a refrigerator 21 in the box body 1, the collected samples can be inserted into the refrigerator for storage when the equipment is in the storage state, thereby coping with a longer period of movement.

[0032] When the test tube rack of the present invention is operated on the handrail, the lifting mechanism starts to work and can be automatically lifted and lowered under the drive of the lifting mechanism. When it is lowered, it can be placed in the refrigerator to refrigerate the collected materials in the test tube. When it is raised, the opening and closing mechanism can open the top cover, so that the test tube rack rises to a position close to the doctor for easy access. At the same time, the expansion storage boxes on both sides of the box body are also unfolded synchronously. When the present invention is in the storage state, the front two sides can form a shoulder strap structure, which is convenient for medical staff to carry it on their back.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
