The bracket of the present application is made of steel material, which has good load-bearing capacity. The load-bearing capacity of the field test exceeds 75KG.

[0033] The frame 3 includes a column and a frame, the two frames are arranged one above the other, there is a gap between the two frames, the two frames are connected as a whole by the columns, and the columns are located at the four corners of the frames. The frame 3 is used to support and fix the first table 1 and the second table 2.

[0034] Specifically, the frame located at the upper part is arranged at the top of the column and is used to install the first table top 1; the frame located at the lower part is arranged at the middle part of the column and is used to install the second table top 2.

[0035] Specifically, the frame includes connecting cross beams and connecting longitudinal beams, and the connecting cross beams and connecting longitudinal beams are sequentially connected end to end to form a quadrilateral frame.

[0036] Specifically, a reinforcement beam is arranged between the bottoms of the two columns connecting the two ends of the cross beam, so as to improve the stability of the lower end of the frame 3.

[0037] Among them, universal wheels are installed at the four corners of the bottom end of the frame body 3. The operator pushes the bracket to move on the ground, which is convenient for moving the bracket.

[0038] Wherein, rubber pads are arranged on the inner walls of the first positioning hole 4 and the second positioning hole 5 to avoid hard friction between the sampling bottle and the positioning hole, thereby preventing the surface of the sampling bottle from being scratched.

[0039] The first table top 1 and the second table top 2 are quadrilaterals.

[0040] The first positioning hole 4 and the second positioning hole 5 are coaxial. The first positioning hole 4 and the second positioning hole 5 are coaxially arranged, which facilitates the placement of the sampling bottle on the second positioning hole 5 through the first positioning hole 4, facilitates the installation of the sampling bottle, and avoids hard friction between the sampling bottle and the positioning hole due to the misalignment of the positioning holes during the installation process.

[0041] The center of the first positioning hole 4 is concentric with the geometric center of the first table 1; the center of the second positioning hole 5 is concentric with the geometric center of the second table 2. The first positioning hole 4 is set at the geometric center of the first table 1, and the second positioning hole 5 is set at the geometric center of the second table 2, so that when the sampling bottle is placed on the bracket, it is prevented from sinking and reducing the overall stability.

The fixed table 101 is fixed to the top of the frame 3, and the sliding table 102 is slidably connected to the top of the frame 3. Through the setting of the sliding table 102, when installing the sampling bottle, the sliding table 102 moves to the side away from the fixed table 101. After the sampling bottle is installed, the sliding table 102 moves to the side close to the fixed table 101 to clamp the sampling bottle; when removing the sampling bottle, the sliding table 102 moves to the side away from the fixed table 101. After the sampling bottle is removed, the sliding table 102 moves to the side close to the fixed table 101 until it fits with the fixed table 101; it is restored to facilitate the installation and removal of the sampling bottle, and can also adapt to different types of sampling bottles, thereby increasing the use range of the bracket and making it more versatile.

Through the arrangement of the sliders 11 and the slide grooves 12, the sliding table 102 moves along the prescribed motion trajectory during the movement process, ensuring that the sliding table 102 does not deviate during the movement process.

[0045] Among them, the pad beam 13 and the slide groove 12 are arranged on two parallel connecting beams, or the pad beam 13 and the slide groove 12 are arranged on two parallel connecting longitudinal beams; each connecting beam or each connecting longitudinal beam is provided with a pad beam 13 and a slide groove 12, and the pad beam 13 is butt-jointed with the end of the slide groove 12, and the pad beam 13 is used to ensure that the upper surfaces of the fixed table top 101 and the sliding table top 102 are flush.

[0046] The cross-sectional shape of the slide groove 12 includes a dovetail shape, a T shape or a rectangle.

[0047] The frame 3 is provided with a transmission assembly, which is connected to the sliding table 102 and is used to drive the sliding table 102 to move toward or away from the fixed table 101. The transmission assembly is used to transmit power to the sliding table 102 to drive the sliding table 102 to move, so that the movement of the sliding table 102 is more stable.

[0048] A connecting beam 6 is provided between the two slide grooves 12, a first bearing seat 7 is provided on the connecting beam 6, a second bearing seat 14 is provided on the top of the frame body 3, and the transmission assembly is installed on the first bearing seat 7 and the second bearing seat 14.

When the piston rod of the electric push rod or hydraulic cylinder is extended, the sliding table 102 moves toward the fixed table 101; when the piston rod of the electric push rod or hydraulic cylinder is retracted into the cylinder body, the sliding table 102 moves along the side away from the fixed table 101.

[0052] A driving member 10 is provided at the end of the lead screw 8 .

[0053] In this embodiment, the driving member 10 is a turntable, and the operator manually rotates the turntable to provide driving force, so that the lead screw 8 rotates in a first direction, so as to drive the sliding table 102 to move along the end away from the fixed table 101 through the transmission component, and the operator manually rotates the turntable to provide driving force, so that the lead screw 8 rotates in a second direction, so as to drive the sliding table 102 to move toward the fixed table 101 through the transmission component. The first direction is opposite to the second direction. The manual control method has the advantage of simple operation.

[0054] When the driving member 10 is a turntable, a perforated extension plate is provided on the outer side of the connecting longitudinal beam on one side of the sliding table 102, a small hole is provided in the lead screw 8 near the end of the turntable, and the screw passes through the small hole on the lead screw 8 and the hole on the perforated extension plate in sequence to prevent the lead screw 8 from rotating under the action of external force, so that the position of the sliding table 102 after moving remains unchanged during the experiment and the sampling bottle cannot be stably clamped.

[0055] When it is necessary to rotate the lead screw 8 along the first direction or the second direction, the screw can be pulled out from the hole.

[0056] In other embodiments, the driving member 10 may also be a motor, which is a servo motor or an asynchronous motor. At this time, the driving member 10 is fixed on the frame 3, and the output shaft of the driving member 10 is connected to the screw 8. The motor provides a driving force so that the screw 8 rotates in a first direction to drive the sliding table 102 to move away from the fixed table 101 through the transmission component; the motor provides a driving force so that the screw 8 rotates in a second direction to drive the sliding table 102 to move toward the fixed table 101 through the transmission component, and the first direction is opposite to the second direction. Automatic control of the sliding table 102 is achieved, the installation and disassembly time of the sampling bottle is reduced, and the experimental efficiency is improved.
