Description

Technical Field

[0001] This utility model relates to the field of automatic air extraction technology, and in particular to an automatic air extraction device for a vacuum exhaust chamber. Background Technology

[0002] An automatic vacuum pump is a device used to automatically extract gas or air. It typically consists of a pump, control module, and sensors. Its core function is to automatically start and stop through preset programs or real-time monitoring, achieving efficient and precise gas extraction. It is widely used in vacuum systems, industrial processes, laboratories, and medical equipment. Many industrial production processes and scientific experiments require extremely high vacuum stability. Automatic vacuum pumps can monitor and maintain a stable vacuum level in real time, ensuring the accuracy of processes or experiments; therefore, an automatic vacuum exhaust chamber pump is necessary.

[0003] An automatic vacuum exhaust chamber extraction device can automatically and efficiently extract gas from the exhaust chamber, quickly achieving the required vacuum state, improving production or experimental efficiency, reducing manual intervention, and lowering the possibility of human error. In existing extraction devices, the installation of extraction pipes is usually fixed with bolts, which is relatively cumbersome. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic vacuum exhaust chamber pumping device, which aims to improve the problem that the installation of the pumping pipe and the pipe is usually fixed by bolts, which is relatively cumbersome.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic vacuum exhaust chamber pumping device, comprising a support frame and a moving component. A pumping unit is fixedly connected to the inner wall of the support frame, and a support frame is fixedly connected to the outer wall of the pumping unit. An exhaust pipe is disposed inside the pumping unit. The outer wall of the support frame is fixedly connected to the outer wall of the exhaust pipe, and a tube is attached to the outer wall of the exhaust pipe. A cylinder is fixedly connected inside the support frame, and a fixing column is fixedly connected to the output end of the cylinder. A rotating shaft is fixedly connected inside the fixing column. A clamping block is rotatably connected to the outer wall of the rotating shaft. A limit block is fixedly connected to the outer wall of the clamping block, and the outer wall of the limit block is fixedly connected to the inside of the support frame. The outer wall of the clamping block is engaged with the outer wall of the tube. A positioning block is fixedly connected to the outer wall of the exhaust pipe, and the outer wall of the tube is engaged with the inner wall of the positioning block.

[0006] The above technical solution involves aligning and fitting the suction pipe with the tube, then using a drive cylinder to move the fixed column back and forth. The fixed column is connected to the clamping block via a rotating shaft. When the fixed column moves back and forth, the clamping block moves synchronously. Due to the limiting offset effect of the limiting block on the outer side of the clamping block, the inner side of the clamping block rotates during movement, thereby achieving the function of clamping and fixing. This further enables the rapid installation and removal of the tube.

[0007] Preferably, the moving component includes a motor, the outer wall of which is fixedly connected to the inside of the support frame, a lead screw is fixedly provided at the output end of the motor, the outer wall of the lead screw is rotatably connected to the inside of the support frame, a slider is threadedly connected to the outer wall of the support frame, a limit strip is slidably connected to the inner wall of the slider, the lower surface of the limit strip is fixedly connected to the inner wall of the support frame, and the outer wall of the fixing column is fixedly connected to the inside of the slider.

[0008] Preferably, wheels are fixedly connected to the lower surface of the load-bearing frame, and a controller is provided on the upper surface of the vacuum pump body.

[0009] Preferably, a filter plate is slidably connected to the inner wall of the air extraction pipe, and a pull ring is rotatably connected to the inside of the filter plate.

[0010] Preferably, the outer wall of the filter plate is provided with a storage groove, and the outer wall of the pull ring is slidably engaged with the inner wall of the storage groove.

[0011] Preferably, a fixing ring is fixedly connected to the outer wall of the filter plate, a connecting ring is slidably connected to the outer wall of the fixing ring, and the outer wall of the connecting ring is fixedly connected to the inner wall of the suction pipe.

[0012] Preferably, a connecting post is fixedly connected to the outer wall of the fixing ring, and the outer wall of the connecting post is slidably connected to the inside of the connecting ring.

[0013] Preferably, a locking block is fixedly connected inside the connecting ring, and the outer wall of the connecting post is engaged with the inner wall of the locking block.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the driving cylinder, through the cooperation of the fixed column, rotating shaft, clamping block and limiting block, can make the clamping block rotate to clamp the pipe. By clamping the pipe, the suction pipe and the pipe can be tightly fitted together. By rotating the clamping block, the clamping and releasing effects can be achieved, thereby realizing the effect of quick installation and disassembly of the pipe, making the operation more convenient.

[0016] 2. In this utility model, impurities in the gas can be filtered through the filter plate. Through the cooperation between the pull ring, the fixing ring, the connecting column, the connecting ring, and the locking block, the connecting column can be engaged or disengaged from the inside of the locking block, thereby achieving quick disassembly of the filter plate, which is convenient for cleaning or replacement and reduces maintenance time.

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1:

[0027] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides an automatic vacuum exhaust chamber extraction device, comprising a support frame 1 and a moving component 14. The inner wall of the support frame 1 is fixedly connected to an extraction machine body 3, and the outer wall of the extraction machine body 3 is fixedly connected to a support frame 6. An extraction pipe 4 is provided inside the extraction machine body 3. The outer wall of the support frame 6 is fixedly connected to the outer wall of the extraction pipe 4. A pipe 5 is attached to the outer wall of the extraction pipe 4. A cylinder 7 is fixedly connected inside the support frame 6. A fixed column 8 is fixedly connected to the output end of the cylinder 7. A rotating shaft 9 is fixedly connected inside the fixed column 8. A clamping block 10 is rotatably connected to the outer wall of the rotating shaft 9. A limiting block 13 is fixedly connected to the outer wall of the clamping block 10. The outer wall of the limiting block 13 is fixedly connected to the inside of the support frame 6. The outer wall of the clamping block 10 is engaged with the outer wall of the pipe 5. A positioning block 11 is fixedly connected to the outer wall of the extraction pipe 4. The outer wall of the pipe 5 is engaged with the inner wall of the positioning block 11.

[0028] Specifically, the load-bearing frame 1 provides fixed support for the vacuum pump body 3. The vacuum pump body 3 is existing technology and can perform vacuuming operations. The vacuum pump body 3 also provides fixed support for the vacuum pipe 4, fixing the pipe 5 to the exhaust chamber that needs to be vacuumed. The vacuum pipe 4 can be connected to the pipe 5, allowing gas to be drawn outwards through the pipe. A sealing ring is provided at the connection between the vacuum pipe 4 and the pipe 5 to ensure airtightness. The vacuum pump body 3 also provides fixed support for the support frame 6, which provides support and fixes the cylinder 7, ensuring its stability. Driving the cylinder 7 causes the fixed column 8 to move back and forth. The fixed column 8 fixes the rotating shaft 9 and is connected to the clamping block 10 via the rotating shaft 9. When the fixed column 8 moves, it drives the clamping block 10 to move simultaneously. Since the clamping block 10 is irregularly shaped, and its outer outer wall is connected to the inner wall of the limiting block 13... The outer side walls roughly match, so when the clamping block 10 moves, the limiting block 13 will limit and offset the outer side of the clamping block 10, thereby allowing the clamping block 10 to rotate near the inner side of the outer wall of the suction pipe 4. By rotating the inner side of the clamping block 10 outward, the outer wall of the pipe 5 can be placed on the inner wall of the positioning block 11. The positioning block 11 provides support and limits the offset of the pipe 5, making it easier to connect the suction pipe 4 and the pipe 5. By driving the fixed column 8 to retract and move through the cylinder 7, the inner side of the clamping block 10 can rotate inward, thereby clamping and fixing the outer wall of the pipe 5. Since the front outer wall of the support frame 6 is close to the outer wall of the suction pipe 4, when the clamping block 10 clamps and fixes the pipe 5, it will cooperate with the support frame 6 to make the suction pipe 4 and the pipe 5 fit tightly together, thereby ensuring the stability of the clamping. Through the clamping action of the clamping block 10, it is easier to install and disassemble the suction pipe 4 and the pipe 5.

[0029] Example 2:

[0030] Reference Figure 2 , Figure 3 and Figure 4 The moving component 14 includes a motor 1401, the outer wall of which is fixedly connected to the inside of the support frame 6. A lead screw 1402 is fixedly provided at the output end of the motor 1401. The outer wall of the lead screw 1402 is rotatably connected to the inside of the support frame 6. A slider 1403 is threadedly connected to the outer wall of the support frame 6. A limit strip 1404 is slidably connected to the inner wall of the slider 1403. The lower surface of the limit strip 1404 is fixedly connected to the inner wall of the support frame 6. The outer wall of the fixing column 8 is fixedly connected to the inside of the slider 1403.

[0031] Specifically, in this embodiment, the support frame 6 has a fixing function for the motor 1401 and a supporting function for the lead screw 1402. The drive motor 1401 can drive the lead screw 1402 to rotate. The lead screw 1402 has a supporting function for the slider 1403. When the lead screw 1402 rotates, it will cause the slider 1403 to move through the thread action. The limiting strip 1404 has a supporting and limiting offset function for the slider 1403, so that the slider 1403 can only move back and forth on the outer wall of the limiting strip 1404. The movement of the slider 1403 will drive the fixing column 8 to move back and forth, thereby enabling the clamping block 10 to achieve the clamping function of the tube 5, which facilitates quick disassembly.

[0032] Reference Figure 1 Wheels 2 are fixedly connected to the lower surface of the load-bearing frame 1, and a controller 12 is provided on the upper surface of the air extraction machine body 3.

[0033] Specifically, the wheels 2 are installed below the load-bearing frame 1, which makes the load-bearing frame 1 easy to move. At the same time, the wheels 2 have a self-locking function to prevent slippage during the air extraction operation. The air extraction operation can be set through the air extraction machine body 3.

[0034] Reference Figure 1 , Figure 5 and Figure 6 A filter plate 15 is slidably connected to the inner wall of the suction pipe 4, and a pull ring 16 is rotatably connected to the inside of the filter plate 15. A storage groove 17 is opened on the outer wall of the filter plate 15, and the outer wall of the pull ring 16 is slidably engaged with the inner wall of the storage groove 17. A fixing ring 18 is fixedly connected to the outer wall of the filter plate 15, and a connecting ring 20 is slidably connected to the outer wall of the fixing ring 18. The outer wall of the connecting ring 20 is fixedly connected to the inner wall of the suction pipe 4. A connecting post 19 is fixedly connected to the outer wall of the fixing ring 18, and the outer wall of the connecting post 19 is slidably connected to the inside of the connecting ring 20. A locking block 21 is fixedly connected to the inside of the connecting ring 20, and the outer wall of the connecting post 19 is engaged with the inner wall of the locking block 21.

[0035] Specifically, the filter plate 15 can filter impurities during the suction process, preventing them from entering the interior of the suction unit 3 and causing damage. The filter plate 15 supports the pull ring 16, and the storage groove 17 on the outer wall of the filter plate 15 can hold the pull ring 16, making the pull ring 16 stable inside the storage groove 17. At the same time, the storage groove 17 is also provided with a semi-circular groove to facilitate pulling up the pull ring 16. The pull ring 16 can drive the filter plate 15 to rotate or pull out the filter plate 15. The fixing ring 18 is fixed to the outer wall of the filter plate 15, and the connecting ring 20 is fixed to the inner wall of the suction pipe 4. The outer wall of the fixing ring 18 can hold... The fixing ring 18 is placed in the slot of the connecting ring 20 and has a fixing effect on the connecting post 19. After the fixing ring 18 and the connecting post 19 are placed into the inner wall of the connecting ring 20, the filter plate 15 is rotated by the pull ring 16, which will cause the fixing ring 18 and the connecting post 19 to slide inside the connecting ring 20. The connecting ring 20 is provided with a locking block 21, and the outer wall of the locking block 21 is provided with a locking groove. By locking the connecting post 19 inside the locking block 21, the fixing ring 18 and the connecting ring 20 can be stably connected. By locking the fixing ring 18 and the connecting ring 20, the filter plate 15 can be quickly installed and removed.

[0036] Working principle: When the device is needed, cylinder 7 is activated. The output end of cylinder 7 moves outward, causing the fixed column 8 to move inside the support frame 6. The movement of the fixed column 8 causes the rotating shaft 9 to move the clamping block 10. Since the clamping block 10 is irregularly shaped, when the clamping block 10 moves upward, the lower side of the clamping block 10 is obstructed by the limiting block 13, causing the upper side of the clamping block 10 to rotate, placing the tube 5 on the inner wall of the positioning block 11 and making the tube 5 fit against the suction pipe 4. At this time, the support... When the output end of the support 6 moves inward, the upper side of the clamping block 10 rotates downward to clamp the tube 5, making the tube 5 fit tightly with the suction pipe 4. At the same time, it is easier to disassemble the tube 5. Similarly, by starting the motor 1401, the lead screw 1402 is rotated. When the lead screw 1402 rotates, it will drive the slider 1403 to move. When the slider 1403 moves, it will drive the fixed column 8 to move, thereby achieving the function of clamping the tube 5 with the clamping block 10.

[0037] When the filter plate 15 needs to be replaced, the filter plate 15 is rotated by pulling the pull ring 16. The rotation of the filter plate 15 will drive the fixing ring 18 to rotate and also cause the connecting column 19 to rotate. The rotating connecting column 19 will disengage from the slot of the locking block 21. At this time, pulling the pull ring 16 outward can remove the filter plate 15 for cleaning and replacement. Conversely, rotating the filter plate 15 will cause the connecting column 19 to be locked in the inner wall of the locking block 21, which can achieve the effect of starting the installation of the filter plate 15. This device can not only quickly install and disassemble the air extraction pipe 4 and the pipe 5 without the need for tools, making it more convenient and time-saving, and reducing the workload of traditional bolt timed retightening, but also quickly disassemble and install the filter plate 15, greatly shortening the maintenance time. In addition, by replacing the filter plate 15 with different media, it can adapt to the usage requirements of different environments.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
