DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1-5 An operating frame for extraction experiments shown in the figure includes a base 1 and an extraction gun 2. A U-shaped mounting plate 3 is fixedly installed on the top of the base 1. A lifting block 4 is slidably installed in the U-shaped mounting plate 3 through a lifting assembly. An electric telescopic rod 7 is arranged on the side of the lifting block 4. Two arc-shaped clamping blocks 8 are fixedly arranged on the output end of the electric telescopic rod 7 through a clamping assembly. A circular groove is provided on the top of the base 1. A rotating motor 13 is fixedly installed on the inner wall of the bottom end of the circular groove. An adjusting circular plate 14 is fixedly installed on the output shaft of the rotating motor 13. A plurality of placement grooves are provided on the top of the adjusting circular plate 14. A placement circular plate 18 is rotatably installed on the top of the U-shaped mounting plate 3 through a linkage assembly. A plurality of storage grooves are arranged on the placement circular plate 18. A retaining ring 22 adapted to the storage groove is fixedly installed on the outer wall of the circumferential side of the extraction gun 2. Limiting assemblies are arranged on the relative inner walls of the plurality of storage grooves.

[0024] By means of the above structure, when in use, firstly, a plurality of extraction liquids are placed in a plurality of placement grooves in a clockwise manner, and a plurality of extraction guns are placed in a plurality of storage grooves in a counterclockwise manner, and then the lifting block 4 is driven to rise to the top by the lifting assembly, and the two arc-shaped clamping blocks 8 are driven to move toward each other under the action of the electric telescopic rod 7 and the clamping assembly, and one of the extraction guns 2 is clamped and fixed, and then it is driven to move horizontally, and is moved out of the storage groove by the squeezing action of the limiting assembly, and then lowered to a suitable position for extraction. When the extraction gun needs to be replaced, the extraction gun 2 is first reset, and the extraction gun 2 can be limited in the storage groove under the joint action of the clamping ring 22 and the limiting assembly, and then the clamping of the extraction gun 2 is released, and the rotating motor 13 is started to drive the adjusting circular plate 14 and the placing circular plate 18 to rotate synchronously toward each other, so as to facilitate the synchronous movement of the adapted extraction gun 2 and the extraction liquid to a suitable position, and then the above steps are repeated to perform the extraction operation. Such a setting can facilitate the use of different extraction guns to perform extraction operations on the extraction liquid, facilitate replacement and placement, and is more practical.

[0025] like Figure 3 As shown, the lifting assembly includes a screw rod 5, the top end of the screw rod 5 is rotatably mounted on the top inner wall of the U-shaped mounting plate 3, the bottom end of the screw rod 5 is rotatably mounted on the top of the base 1, the lifting block 4 is threadedly mounted on the screw rod 5, and a motor slot is provided at the top of the base 1, in which a lifting motor 6 is fixedly installed, and the output shaft of the lifting motor 6 is connected to the end of the screw rod 5. The advantage of such a setting is that the lifting block 4 can be driven by the screw rod 5 to realize lifting movement.

[0026] Specifically, the lifting motor 6 is started to drive the screw 5 to rotate, and then the lifting block 4 can be driven to achieve lifting movement under the action of the thread, so that the lifting block 4 can drive the electric lifting rod 7, the clamping assembly, and the extraction gun 2 to a suitable position for operation.

[0027] like Figure 3 As shown, the clamping assembly includes a rectangular block 9, which is fixedly mounted on the output end of the electric telescopic rod 7. A transmission groove is provided on the side of the rectangular block 9, and a bidirectional screw rod 10 is installed on the relative inner walls of the transmission groove for common rotation. A device groove is provided on the side inner wall of the transmission groove, and a clamping motor 11 is fixedly installed in the device groove. The output shaft of the clamping motor 11 is connected to the end of the bidirectional screw rod 10, and two connecting rods 12 are threadedly mounted on the bidirectional screw rod 10. The two connecting rods 12 are respectively fixedly connected to the two arc-shaped clamping blocks 8. The advantage of such a setting is that the two connecting rods 12 and the two arc-shaped clamping blocks 8 are driven by the bidirectional screw rod 10 to move toward each other, so that the clamping and fixing function of the extraction gun 2 can be realized.

[0028] Specifically, when the extraction gun 2 needs to be clamped, the clamping motor 11 is started to drive the bidirectional screw 10 to rotate, and the two connecting rods 12 and the two arc-shaped clamping blocks 8 are driven to move synchronously toward each other, so as to clamp and fix the extraction gun 2, and the clamping effect is more stable.

[0029] like Figure 1 and Figure 2 As shown, the linkage assembly includes a rotating shaft 15, a connecting groove connected to the circular groove is opened in the base 1, and the rotating shaft 15 is rotatably installed at the bottom of the connecting groove. The top end of the rotating shaft 15 extends to the outside of the U-shaped mounting plate 3 and is fixedly connected to the bottom end of the placed circular plate 18. The rotating shaft 15 is connected to the rotating motor 13 through a transmission unit. The advantage of this arrangement is that through the arrangement of the rotating shaft 15, the placed circular plate 18 can realize the rotation function.

[0030] Specifically, by arranging the placement circular plate 18 at the top of the rotating shaft 15, when the rotating motor 13 is working, the rotating shaft 15 and the placement circular plate 18 can be driven to rotate synchronously in opposite directions under the action of the transmission unit.

[0031] like Figure 4 As shown, the transmission unit includes two sprockets 16, and the two sprockets 16 are fixedly sleeved on the rotating shaft 15 and the output shaft of the rotating motor 13 respectively. A chain 17 is installed on the two sprockets 16 in meshing relationship. The advantage of such an arrangement is that, through the arrangement of the two sprockets 16 and the chain 17, the rotating shaft 15 can be driven to rotate synchronously by rotating the output shaft of the rotating motor 13.

[0032] Specifically, when the rotating motor 13 is working, it drives one of the sprockets 16 to rotate, and then drives the other sprocket 16 and the rotating shaft 15 to rotate synchronously under the meshing action of the sprocket 16 and the chain 17, without the need to set up an additional driving power supply, and the linkage effect is better.

[0033] like Figure 5 As shown, the limit assembly includes two limit blocks 19, and the relative inner walls of the storage slot are provided with sliding grooves. The two limit blocks 19 are respectively slidably installed in the two sliding grooves. The sides of the two limit blocks 19 are provided with compression units, and the compression unit includes a compression spring 21. The side of the limit block 19 is provided with a guide groove, and a guide shaft 20 is fixedly installed on the side inner wall of the sliding groove. The other end of the guide shaft 20 is slidably installed in the guide groove, and the compression spring 21 is sleeved on the guide shaft 20. One end of the compression spring 21 is fixedly installed on the side inner wall of the sliding groove, and the other end of the compression spring 21 is fixedly installed on the side of the limit block 19. The advantage of such an arrangement is that, through the arrangement of the two limit blocks 19, when the extraction gun 2 is placed in the storage slot, it can be limited by the two limit blocks 19 to prevent it from falling off during rotation.

[0034] Specifically, when the extraction gun 2 moves horizontally in the storage tank, the two limit blocks 19 can be driven to move synchronously in opposite directions under the extrusion effect, thereby squeezing the two compression springs 21 to facilitate their horizontal movement, and when the squeezing effect on the two limit blocks 19 disappears, the two limit blocks 19 can be driven to reset under the elastic action of the two compression springs 21, thereby realizing the limiting function.

[0035] like Figure 1 As shown, a plurality of suction cups 23 are fixedly installed on the bottom of the base 1. The advantage of such an arrangement is that, through the arrangement of the plurality of suction cups 23, the base 1 can be made more stable when placed.

[0036] Specifically, when the base 1 is placed on a desktop, gravity drives the plurality of suction cups 23 to form a negative pressure state, thereby improving the stability performance through adsorption.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
