When sealing the sealing cover 3, a fixing structure composed of a butterfly nut 20 and a screw 19 is adopted. Usually, eight of the above fixing structures are arranged on the outer edge of the sealing cover 3. Specifically, one end of the screw 19 is fixed to the upper end of the non-slip base 2, and the other end of the screw 19 passes through the positioning hole opened in the sealing cover 3. When fixing, it is necessary to align the eight positioning holes on the surface of the sealing cover 3 with the screw 19 and insert them for positioning, and then the butterfly nuts 20 are sleeved on the top of the screw 19 one by one and tightened. When the test is finished and disassembled, it is necessary to loosen the butterfly nuts 20 one by one to separate the butterfly nuts 20 from the top of the screw 19 before the sealing cover 3 can be opened. The above operation usually takes a lot of time, which is not conducive to improving the efficiency of the test. Utility Model Content

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] See also Figure 1-Figure 4 The utility model provides a technical solution: a connection structure of a reaction kettle, comprising a kettle body 1 and a cover 3 detachably arranged on the upper end of the kettle body 1, and the bottom of the kettle body 1 has a non-slip base 2;

[0033] like Figure 1 and Figure 2As shown, the connection structure also includes: a bracket 5 connected to the anti-slip base 2; a pressing plate 7 and a lifting component for driving the pressing plate 7 to press the upper end of the cover 3, one end of the lifting component is connected to the bracket 5; in this embodiment, the lifting component is an electric telescopic rod 6, the base of the electric telescopic rod 6 is connected to the bracket 5, and the output end of the electric telescopic rod 6 is connected to the pressing plate 7; the upper end of the pressing plate 7 is provided with a through hole 8 for the feeding port 4 at the upper end of the cover 3 to pass through, and the through hole 8 can be set larger and set to an annular groove structure;

[0034] By adopting the above technical solution, the pressure plate 7 can be used to press the upper end of the cover 3, so as to seal the kettle body 1. The cover 3 is roughly placed at the center of the upper end of the kettle body 1, and the electric telescopic rod 6 is started to drive the pressure plate 7 to move downward until the pressure plate 7 presses the cover 3. The through opening 8 is set to an annular groove structure to ensure that no matter how the angle of the cover 3 changes, the feed port 4 can pass through the through opening 8, so as to facilitate subsequent automatic calibration.

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, the connection structure further includes: a calibration component for calibrating the position of the cover 3 at the upper end of the kettle body 1, the calibration component including at least two calibration parts arranged opposite to each other;

[0036] The above technical solution can ensure that the cover 3 can be placed at the center of the upper end of the kettle body 1 without deviation.

[0037] like Figure 3 and Figure 4 As shown, the calibration unit includes:

[0038] a slide plate 9 slidably connected to the bracket 5; in this embodiment, the bracket 5 is provided with a slide groove 10 adapted to the shape of the slide plate 9, so that the slide plate 9 can slide in the slide groove 10; a calibration plate 11 provided at one end of the slide plate 9; in this embodiment, since the cover 3 is a circular plate structure, the calibration plate 11 is a plate structure with an arc groove;

[0039] The linkage assembly is used to synchronously drive the slide plate 9 to slide toward the cover 3 when the pressing plate 7 presses the cover 3 downward, thereby driving the calibration plate 11 to push the cover 3 to the center of the kettle body 1; in this embodiment, the linkage assembly includes: a fixed block 12 connected to the pressing plate 7, the fixed block 12 is provided with a through slot 13 for the slide plate 9 to pass through; a guide column 14 provided on the side of the slide plate 9, the guide column 14 is slidably matched with a guide slot 15 provided on the side of the fixed block 12;

[0040] The adoption of the above technical scheme can ensure that the position of the cover 3 can be automatically calibrated during the positioning of the cover 3. When the kettle body 1 needs to be sealed, the cover 3 is roughly placed at the center of the upper end of the kettle body 1, and the electric telescopic rod 6 is started to drive the pressure plate 7 to move downward. During the downward movement of the pressure plate 7, the fixed block 12 connected to it will be driven to move downward synchronously, so that the guide groove 15 on the surface of the fixed block 12 is aligned with the guide column 14 on the side of the slide plate 9 and embedded. As the pressure plate 7 continues to move downward, the guide column 14 will be driven to slide along the guide groove 15, thereby driving the slide plate 9 to move toward the cover 3, so that the calibration plate 11 pushes the cover 3 to the center position of the upper end of the kettle body 1. When the cover 3 is located at the center position of the upper end of the kettle body 1, the pressure plate 7 just presses the cover 3, thereby automatically calibrating and fixing the cover 3, and the efficiency is relatively high.

[0041] Further, such as Figure 4 As shown, the linkage assembly further includes: a fixing plate 16 disposed at the upper end of the slide plate 9; a reset member 17 connected to the fixing plate 16 at one end, and the other end of the reset member 17 is connected to the bracket 5; and a limit plate 18 disposed at the lower end of the slide plate 9;

[0042] The adoption of the above technical solution can ensure that the slide plate 9 can automatically reset. When the electric telescopic rod 6 drives the pressure plate 7 to rise and reset to release the lock on the cover 3, due to the provision of the reset member 17, when the guide groove 15 of the fixed block 12 is out of contact with the guide column 14 of the slide plate 9, the reset member 17 can drive the slide plate 9 to slide and reset along the slide groove 10. Moreover, due to the provision of the limit plate 18, it can be ensured that when the limit plate 18 is in contact with the bracket 5, the slide plate 9 stops sliding, so that the guide column 14 is just below the opening of the guide groove 15 for the next positioning.

[0043] Working principle: when the kettle body 1 needs to be sealed, the sealing cover 3 is roughly placed at the center of the upper end of the kettle body 1, and the electric telescopic rod 6 is started to drive the pressing plate 7 to move downward. During the downward movement of the pressing plate 7, the fixed block 12 connected thereto will be driven to move downward synchronously, so that the guide groove 15 on the surface of the fixed block 12 is aligned with the guide column 14 on the side of the slide plate 9 and embedded. As the pressing plate 7 continues to move downward, the guide column 14 will be driven to slide along the guide groove 15, thereby driving the slide plate 9 to move toward the sealing cover 3, so that the calibration plate 11 pushes the sealing cover 3 to the center position of the upper end of the kettle body 1. When the sealing cover 3 is located at the center position of the upper end of the kettle body 1, the pressing plate 7 just presses the sealing cover 3, thereby automatically calibrating and automatically fixing the sealing cover 3, with high efficiency;

[0044] When it is necessary to open the kettle body 1, the electric telescopic rod 6 is started to drive the pressure plate 7 to rise and reset, thereby driving the calibration plate 11 away from the cover 3 and releasing the lock on the cover 3. At this time, the cover 3 can be removed from the upper end of the kettle body 1. Due to the provision of a reset member 17, when the guide groove 15 of the fixed block 12 is out of contact with the guide column 14 of the slide plate 9, the reset member 17 can drive the slide plate 9 to slide and reset along the slide groove 10, and due to the provision of a limit plate 18, it can be ensured that when the limit plate 18 is in contact with the bracket 5, the slide plate 9 stops sliding, so that the guide column 14 is just located directly below the opening of the guide groove 15 for the next positioning.

[0045] Thus, a series of tasks are completed, and the circuits, electronic components and modules involved are all existing technologies, which can be fully implemented by those skilled in the art. Needless to say, the content protected by this utility model does not involve improvements to software and methods.

[0046] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
