[0039] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0040] like Figure 1-3 As shown, a sample tube supporting device comprises:

[0041] Base 1;

[0042] Two guide rails 2, the two guide rails 2 are arranged in parallel on the base 1;

[0043] A pair of sliding support seats 3, the pair of sliding support seats 3 are slidably mounted on the guide rail 2, and the sliding support seats 3 are provided with V-shaped support grooves;

[0044] A plurality of rollers 4 are rotatably arranged in a V-shaped support groove, and the V-shaped support groove is suitable for placing a sample tube.

[0045] In this embodiment, if Figure 1 As shown, first, the length of the sample tube is adapted by adjusting the position of a pair of sliding support seats 3 on the guide rail 2. After the adjustment is completed, the sample tube is placed in the V-shaped support groove on the sliding support seat 3. With the cooperation of the roller 4, the sample tube placed in the V-shaped support groove can be easily rotated, so that the sample tube can be conveniently inspected in all directions. In some embodiments, the number of guide rails 2 is not limited to two, and can be set according to specific needs.

[0046] Specifically, Figure 1 As shown, the sample tube support device also includes a sliding support seat movement driving mechanism suitable for driving the sliding support seat 3 to move. The sliding support seat movement driving mechanism can be the following structure, including:

[0047] A driving source 51, wherein the driving source 51 is fixed on the base 1;

[0048] A bidirectional screw rod 52, the bidirectional screw rod 52 is rotatably mounted on the base 1, and the bidirectional screw rod 52 is connected to the driving source 51;

[0049] A pair of nuts, the pair of nuts are respectively threadedly connected to the threads at both ends of the bidirectional screw rod 52, and are respectively fixedly connected to the corresponding sliding support seats 3;

[0050] The driving source 51 is suitable for driving the bidirectional screw rod 52 to rotate, so as to drive a corresponding pair of sliding support seats 3 to move relative to or away from each other through a pair of nuts.

[0051] In this embodiment, if Figure 1 As shown, the function of the sliding support seat moving driving mechanism is to drive the two sliding support seats 3 to move toward or away from each other on the guide rail 2, thereby adjusting the distance between the two sliding support seats 3 to accommodate sample tubes of different lengths.

[0052] The driving source 51 drives the bidirectional screw rod 52 connected thereto to rotate, and the bidirectional screw rod 52 is threadedly connected to the corresponding nut. When the bidirectional screw rod 52 rotates, the two nuts move toward or away from each other on the bidirectional screw rod 52, thereby driving the two sliding support seats 3 to move toward or away from each other on the guide rail 2. The driving source 51 can be a motor.

[0053] In addition, in some embodiments, two one-way screws can be used instead of the two-way screws. Each one-way screw is driven to rotate by a driving source 51. The sliding support seat 3 is connected to the corresponding one-way screw through a corresponding nut. The two driving sources 51 respectively drive the two one-way screws to rotate, thereby driving the two sliding support seats 3 to move toward or away from each other.

[0054] Specifically, Figure 1 As shown, sliding limiting blocks 21 are also provided at both ends of the guide rail 2.

[0055] In this embodiment, if Figure 1 As shown, the function of the sliding limiting block 21 is to limit the sliding range of the sliding support seat 3 on the guide rail 2 to prevent the sliding support seat 3 from sliding off from both ends of the guide rail 2.

[0056] The sliding limit block 21 is located at both ends of the guide rail 2. When the sliding support seat 3 moves to the end of the guide rail 2, it will resist the sliding support seat 3 and limit its further movement. In this way, the sliding support seat 3 can be ensured to slide safely within the specified range of the guide rail 2 to avoid accidental falling off. The sliding limit block 21 can reliably block the sliding support seat 3 without affecting the sliding of the sliding support seat 3 within the normal range.

[0057] Specifically, Figure 1-2 As shown, the sample tube supporting device further includes a frame 6 , which is mounted on the base 1 .

[0058] Specifically, Figure 1-2 As shown, the frame 6 includes a lower support frame 61 and a telescopic frame 62;

[0060] A height adjustment mechanism is also provided between the lower support frame 61 and the telescopic frame 62;

[0061] The height adjustment mechanism is suitable for driving the telescopic frame 62 and the base 1 to move up and down on the lower support frame 61 .

[0062] In this embodiment, if Figure 1-2 As shown, the function of the frame 6 and the height adjustment mechanism is to enable the height of the entire sample tube supporting device to be adjusted in the vertical direction.

[0063] In some embodiments, the height adjustment mechanism may also use a hydraulic cylinder to drive the telescopic frame 62 to move up and down.

[0064] Specifically, Figure 1-2 As shown, a cross bar is provided on the lower support frame 61;

[0065] The height adjustment mechanism may have the following structure, including:

[0066] The screw rod 71 is vertically installed below the base 1 and passes through the cross bar;

[0067] An adjusting nut, wherein the adjusting nut is threadedly connected to the lead screw;

[0068] The adjusting nut is rotatably connected to the cross bar, and the adjusting nut is suitable for being rotated to drive the screw rod 71 to move up and down, thereby driving the telescopic frame 62 and the base 1 to move up and down.

[0069] In this embodiment, if Figure 1-2 As shown, the screw rod 71 is vertically installed below the base 1 and passes through a crossbar on the lower support frame 61. The thread of the adjusting nut is threadedly connected to the screw rod 71. When the adjusting nut is manually rotated, the adjusting nut drives the screw rod 71 to perform a lifting linear motion, thereby driving the entire telescopic frame 62 and the base 1 and other components mounted thereon to lift together.

[0070] Specifically, Figure 2 As shown, the height adjustment mechanism further includes a manual rotating handle 73, and the manual rotating handle 73 is fixedly connected to the adjustment nut.

[0071] In this embodiment, if Figure 2 As shown, the user can hold the manual rotating handle 73 and turn it vigorously, thereby driving the adjusting nut to rotate. The setting of the manual rotating handle 73 makes manual height adjustment more labor-saving and convenient.

[0072] Specifically, Figure 1-2 As shown, a plurality of fixing threaded holes 63 are also provided at the bottom of the frame 6 .

[0073] In this embodiment, if Figure 1-2 As shown, the function of the multiple fixing threaded holes 63 arranged at the bottom of the frame 6 is to facilitate the entire sample tube supporting device to be firmly fixed and installed on the ground.

[0074] These threaded holes 63 are provided at the bottom of the lower support frame 61 of the frame 6. During use, the bottom of the device can be aligned with the pre-opened hole of the installation position, and then the bolts are passed through and screwed into the threaded holes 63, and the device can be tightened and fixed.

[0075] The threaded hole fixing method is not only reliable and firm, but also easy to remove and reinstall to other locations. Only a few bolts are needed to complete the fixing or removal.

[0076] Specifically, Figure 1 and Figure 3 As shown, the sample tube support device also includes a sample tube upper limit mechanism, and the sample tube upper limit mechanism can be the following structure, including:

[0077] The limiting frame 81 is detachably and slidably mounted on the sliding support seat 3. The limiting frame 81 and the corresponding sliding support seat 3 form a sample tube groove for accommodating the sample tube. A threaded hole is provided on the top of the limiting frame 81;

[0078] A limiting abutment member 82, wherein the limiting abutment member 82 is threadedly connected to the threaded hole of the limiting frame 81, and the lower end portion of the limiting abutment member 82 is a limiting abutment surface;

[0079] The limiting abutment member 82 is suitable for being rotated and then raised and lowered on the limiting frame 81 to abut against the sample tube on the V-shaped support groove of the sliding support seat 3 .

[0080] In this embodiment, if Figure 1 and Figure 3 As shown, the function of the sample tube upper limit mechanism is to adjust and limit the upper limit position of the sample tube in the V-shaped support groove of the sliding support seat to prevent the sample tube from escaping from the V-shaped support groove.

[0081] When in use, first slide the limiting frame 81 to a suitable position of the sliding support seat 3, and then rotate the limiting abutment member 82 to move up and down in the limiting frame 81 until the abutment surface touches the sample tube placed in the V-shaped support groove. In this way, the sample tube is limited at a certain position.
