The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0027] A sample feeding device, as shown in Figures 1-5 includes a housing, a support plate 5, a plurality of first through holes 51, a plurality of clamping mechanisms 7 and a plurality of limiting mechanisms 8.

[0028] Among them, as shown in Figures 1-2As shown, the shell has side walls and a bottom wall, and is in the shape of a cylinder. Specifically, the shell includes a lower shell 1, a transparent shell 2, and an upper shell 3. The lower shell 1 includes a bottom wall and a side wall. The transparent shell 2 is fixedly connected to the side wall of the lower shell 1, and the upper shell 3 is fixedly connected to the transparent shell 2. The side wall of the shell is formed by the side wall of the lower shell 1, the transparent shell 2, and the upper shell 3, and the bottom wall of the shell is formed by the bottom wall of the lower shell 1.

[0029] like Figures 2-3 As shown, the support plate 5 is disposed inside the housing; specifically, the support plate 5 is disc-shaped and fixedly connected to the inner side of the upper housing 3, and its outer wall is fixedly connected to the inner wall of the upper housing 3; the support plate 5 has a plurality of first through holes 51, second through holes 52 and third through holes 53 arranged in a ring array, the shape of the first through hole 51 is adapted to the shape of the test tube 6; the number of the first through holes 51, second through holes 52 and third through holes 53 is selected according to the number of clamping mechanisms 7 and limiting mechanisms 8, and no limit is imposed on the number here;

[0030] like Figures 3-4 As shown, the clamping mechanism 7 is mounted on the support plate 5 and is used to clamp and fix the test tube 6. Specifically, the clamping mechanism 7 includes two clamping components arranged symmetrically. Each clamping component includes a rotating seat 71 fixedly connected to the support plate 5, a swing arm 72 rotatably connected to the rotating seat 71, and a torsion member between the swing arm 72 and the rotating seat 71. The torsion member is a torsion spring 76, one end of which is fixedly connected to the rotating seat 71 and the other end is fixedly connected to the swing arm 72. A clamping member 73 is fixedly connected to the swing arm 72. The test tube 6 is inserted into the first through hole 51 and clamped and fixed by the clamping members 73 of the two clamping components.

[0031] It is understandable that the operator can insert the test tube 6 containing the sample into the first through hole 51. After the test tube 6 is inserted into the first through hole 51, it continues to be inserted downwards. At this time, the test tube 6 will squeeze the clamping member 73, and the torsion spring 76 will deform. Finally, the test tube 6 will be inserted between the two clamping members 73. The tension generated by the deformation of the torsion spring 76 can make the two clamping members 73 clamp and fix the test tube 6, thereby preventing the test tube 6 from moving on the first through hole 51 during the sample delivery process, which would cause the test tube 6 to break.

[0032] like Figures 4-5As shown, the support plate 5 is provided with a plurality of limiting mechanisms 8 corresponding to the clamping mechanism 7; the limiting mechanism 8 is used to avoid the swing arm 72 from swinging during the sample sending process, so as to cause the clamping piece 73 to not stably clamp the test tube 6; specifically, the limiting mechanism 8 comprises a pressing frame slidingly connected on the support plate 5 and a driving assembly for driving the pressing frame to slide, and the pressing frame blocks the two clamping assemblies, so that the two clamping assemblies cannot rotate outward.

[0033] It can be understood that after the clamping assembly clamps the test tube 6, the operator drives the driving assembly to move the pressing frame to the direction close to the clamping assembly, and the movement of the pressing frame to the direction close to the clamping assembly will block the swing arm 72 of the clamping assembly, so that the swing arm 72 cannot move outward, so that the clamping assembly can sufficiently clamp and fix the test tube 6; on the contrary, the operator can also drive the driving assembly to make the pressing frame no longer block the swing arm 72, so that the operator can take out the test tube 6 from the first through hole 51.

[0034] The pressing frame comprises a sliding piece 82 slidingly connected on the support plate 5 and two blocking pieces 81 provided on both sides of the sliding piece 82, and the two blocking pieces 81 are used to block the two clamping assemblies, so that the two clamping assemblies cannot rotate outward.

[0035] The sliding piece 82 slides in the third through hole 53, and the two blocking pieces 81 are integrally formed with the sliding piece 82, and the blocking piece 81 is used to block the swing arm 72 of the two clamping assemblies, so that the swing arm 72 cannot rotate outward.

[0036] As shown in the figure, Figure 3 The inner side of the clamping piece 73 is provided with a buffer 74, and the buffer 74 is in contact with the test tube 6.

[0037] The buffer 74 is fixedly connected to the inner side of the clamping piece 73, and the buffer 74 is made of flexible material, preferably rubber or silicone material, and through the arrangement of the buffer 74, when the clamping piece 73 clamps the test tube 6, the rigid contact of the clamping piece 73 to the test tube 6 can be avoided, so as to cause the test tube 6 to be damaged.

[0038] As shown in the figure, Figure 4 The end of the blocking piece 81 close to the side of the clamping assembly is a bevel 83, and the bevel 83 is used to extrude the swing arm 72 of the blocking piece 81.

[0039] It can be understood that the blocking piece 81 moves to the direction close to the swing arm 72, and the swing arm 72 is extruded through the bevel 83, so that the swing arm 72 further swings to the direction of the test tube 6, and at this time, the buffer 74 is more closely in contact with the test tube 6, and further fixes the test tube 6.

[0040] As Figure 5 shown, the drive assembly includes a magnetic sheet 84 arranged on the extrusion frame, and an electromagnet 85 arranged on the support plate 5, the electromagnet 85 is magnetically attracted to the magnetic sheet 84; the support plate 5 is provided with a switch 86 near the opening of the shell, the switch 86 is used to control the start of all drive assemblies electromagnet 85.

[0041] Among them, the magnetic sheet 84 is fixed on the extrusion frame, the electromagnet 85 is fixedly connected on the support plate 5, and the switch 86 is also fixedly connected on the support plate 5; it can be understood that pressing the switch 86 once, the electromagnet 85 will obtain the same magnetic pole as the magnetic sheet 84, at this time the electromagnet 85 will attract the magnetic sheet 84 to move the magnetic sheet 84 to the direction of the electromagnet 85, the magnetic sheet 84 drives the extrusion frame to move, thereby the extrusion frame no longer extrudes the swing arm 72; press the switch 86 again, at this time the electromagnet 85 generates a magnetic pole opposite to the magnetic sheet 84, which drives the magnetic sheet 84 to move to the direction close to the swing arm 72, so that the extrusion frame extrudes the swing arm 72.

[0042] As Figure 3 shown, the swing arm 72 of the two clamping assemblies is provided with a swing rod 75, the swing rod 75 passes through the support plate 5 and is exposed on the upper part of the support plate 5.

[0043] Among them, the swing rod 75 is fixedly connected on the swing arm 72, and the swing rod 75 passes through a part of the second through hole 52 and is located above the support plate 5; when the operator needs to take out the test tube 6 from the first through hole 51, the operator can fold the two swing rods 75, at this time the swing arm 72 rotates outward, and the clamping piece 73 no longer clamps the test tube 6, at this time the test tube 6 can be taken out from the first through hole 51.

[0044] As Figure 3 shown, a plurality of grooves 11 corresponding to the first through hole 51 are formed on the inner bottom wall of the shell, and a protection pad 12 is arranged in the groove 11.

[0045] It can be understood that a plurality of grooves 11 are formed on the inner side of the lower shell 1, when the test tube 6 passes through the first through hole 51 and finally inserts into the groove 11, by fixedly connecting the protection pad 12 in the groove 11, the test tube 6 can be protected, the material of the protection pad 12 is preferably rubber or silica gel, so as to avoid the lower part of the test tube 6 and the side wall of the groove 11 rigidly contact, causing damage.

[0046] As Figure 1 and Figure 2 shown, a transparent part is arranged on the side wall of the shell, through which the test tube 6 in the shell can be viewed.

[0047] It can be understood that the transparent part is also the transparent shell 2, through the transparent shell 2, the operator can view the situation of the test tube 6 in the shell, avoiding sending the empty test tube 6 into the laboratory.

[0048] As shown in the drawings, the opening of the shell is provided with a closure cover 4. Figure 1

[0049] It can be understood that the closure cover 4 includes the closure cover 4, which is threadedly connected with the opening of the shell, and of course in other embodiments, the closure cover 4 can be connected with the opening of the shell through a zipper, and a handle 42 is arranged in the top wall of the closure cover 4, through which the whole sample sending device can be held in the hand, achieving the effect of convenient carrying.

[0050] As described above, the tension generated by the torsion spring 76 can make the two clamping members 73 clamp and fix the test tube 6, thereby avoiding the movement of the test tube 6 on the first through hole 51 during the sample sending process, causing the test tube 6 to be damaged; and by starting the driving assembly, the pressing frame moves towards the clamping assembly, which blocks the swing arm 72 of the clamping assembly, so that the swing arm 72 cannot move outward, so that the clamping assembly can fully clamp and fix the test tube 6, avoiding the shaking of the test tube 6 during the sample sending process.
