Description

Technical Field

[0001] The utility model belongs to the technical field of manual rotating mechanisms, and in particular relates to a manual rotating mechanism for a vacuum cavity. Background Art

[0002] The vacuum system includes pumping speed control, air intake filtration, main operation data display, operation protection and remote control interface, etc. It only needs to simply connect the power supply and pipeline on site to form a complete vacuum system. The vacuum system needs to be connected through pipelines during installation. However, when the pipelines are connected, the flange holes on different pipelines are prone to misalignment, which leads to the need to flip the pipeline connection after it is fixed.

[0003] For example, the patent with application number 202320442804.1 discloses a vacuum pipe suitable for a vacuum furnace, including a vacuum pipe body and a connecting pipe, wherein a flange 1 is fixedly installed on the vacuum pipe body, and a spring is fixedly connected to the inner wall of the slide groove so that the spring is compressed by force, and then the user rotates the rotating ring to rotate the two blocks so that the two blocks are respectively movably engaged in the slots. At this time, the two blocks will be misaligned with the two blocks, and the elastic reset action of the spring will be used to reset the two blocks. At this time, the two blocks will be inserted into the grooves, and the two blocks will be blocked by the blocks so that the blocks will not be separated from the slots, thereby completing the connection and fixation between the rotating ring and the connecting ring.

[0004] The above technical solution uses flanges and bolts for connection. However, after one end of the pipe is fixed, the other end of the pipe cannot be rotated during installation due to the fixation, which makes it difficult for the hole on the pipe flange to return to its original position, resulting in low efficiency of flange installation on the pipe.

[0005] (1) Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a manual rotating mechanism for a vacuum chamber, which aims to solve the problem in the prior art that after one end of the pipeline is fixed, the other end of the pipeline cannot be rotated during installation due to the influence of the fixation, which makes it difficult for the hole on the pipeline flange to return to its original position, resulting in low efficiency in the installation of the flange on the pipeline.

[0007] (2) Technical solution

[0008] In order to solve the above technical problems, the utility model provides a manual rotating mechanism for a vacuum chamber, which includes a connecting pipe and an installation box rotatably arranged on the connecting pipe, a fixed flange is installed at one end of the connecting pipe, and an O-ring is fixedly sleeved on the other end of the connecting pipe, and a rotating flange is rotatably sleeved through the O-ring, wherein a worm gear is fixedly sleeved at the center position of the connecting pipe, a worm screw meshing with the worm gear is rotatably arranged in the installation box, and a rotating handwheel for driving the worm screw to rotate is rotatably arranged on the side wall of the installation box.

[0009] When the manual rotation mechanism of the vacuum chamber of the present technical solution is used, a fixing frame and an installation box are rotated on the connecting pipe. After the rotating flange at one end of the connecting pipe is fixed to the sealing pipe through the through hole, the rotating hand wheel and the driving rod are driven to rotate by the handle. During the rotation process, the driving rod drives the connecting pipe and the fixed flange to rotate through the worm and the worm gear, so that the through hole on the uninstalled fixed flange corresponds to the pipe. During the rotation process, the connecting pipe is sealed with the rotating flange through the O-ring, which facilitates the rotation and installation of the connecting pipe, thereby improving the convenience of installation of the rotating pipe.

[0010] Preferably, both ends of the connecting pipe are fixedly sleeved with mounting bearings, a fixing frame is provided between the two mounting bearings, and the bottom end of the mounting box is fixedly connected to the fixing frame.

[0011] Furthermore, a driving rod is rotatably arranged in the installation box, and the worm is fixedly sleeved on the driving rod.
