Description

Technical Field

[0001] This utility model relates to the field of nitrogen and oxygen analyzer technology, and in particular to a nickel bladder clamping device for a nitrogen and oxygen analyzer. Background Technology

[0002] A nickel bladder clamping device for a nitrogen and oxygen analyzer is an auxiliary device specifically designed to securely clamp the nickel bladder during nitrogen and oxygen analysis. This device achieves precise positioning and clamping of the nickel bladder through a mechanical structure, ensuring its stability during analysis and thus improving the accuracy and reliability of nitrogen and oxygen analysis.

[0003] In existing technologies, the fixing and clamping of the nickel bladder is typically done manually. The operator needs to place the nickel bladder in a specific position on the analyzer and then secure it by tightening the nut or manually pressing down the clamping block. The specific operating steps are as follows: First, place the nickel bladder on the analyzer's mounting base; next, manually tighten the nut or press down the clamping block to clamp the nickel bladder; finally, begin nitrogen and oxygen analysis. After the analysis is complete, the operator needs to manually loosen the nut or clamping block and remove the nickel bladder.

[0004] Existing manual clamping techniques have limited precision, making it difficult to guarantee consistent force and accuracy in tightening the nickel bladder each time. This can lead to loosening of the bladder during analysis, affecting the accuracy of the results. Furthermore, manual clamping is susceptible to human error, especially during prolonged continuous operation, where operator fatigue further increases the probability of errors. Therefore, this paper proposes a nickel bladder clamping device for nitrogen and oxygen analyzers to address these issues. Utility Model Content

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

[0026] Reference Figure 1 , Figure 2This utility model provides an embodiment of a nickel bladder clamping device for a nitrogen and oxygen analyzer, comprising a base frame 1, which serves as the basic support structure for the entire device, providing a stable mounting platform for the placement plate 2 and other components, ensuring the stability of the entire device. The top of the base frame 1 is fixedly connected to the placement plate 2, which supports the base 7 and the support plate 3, serving as an intermediate connection and support. The top of the placement plate 2 is fixedly connected to the base 7, and the top of the base 7 is fixedly connected to a fixing block 6. The top of the base 7 contacts a pressing block 5. The top of the placement plate 2 is fixedly connected to the support plate 3, which is used to install a cylinder 4 for gas... Cylinder 4 provides stable support to ensure that cylinder 4 can work normally. Cylinder 4 is fixedly connected to the front of support plate 3. Through the extension and retraction of cylinder push rod, the extrusion block 5 is moved to realize the pressing and releasing operation of nickel bag. Cylinder push rod is slidably connected to the inner wall of cylinder 4. The end of cylinder push rod is fixedly connected to the left side of extrusion block 5. A semi-circular protrusion is fixedly connected to the right side of extrusion block 5. A semi-circular groove is opened on the left side of fixed block 6. The semi-circular protrusion is adapted to the semi-circular groove. A semi-circular protrusion is fixedly connected to the right side of extrusion block 5 to cooperate with the semi-circular groove of fixed block 6 to realize the pressing of nickel bag.

[0027] Reference Figure 3 - Figure 5 The fixing block 6 is equipped with a positioning structure, which includes a rotating rod 11. An extension plate A13 and an extension plate B14 are fixedly connected to the right side of the fixing block 6, providing support and a mounting base for the rotating rod 11 to ensure stable rotation. The bottom end of the rotating rod 11 penetrates the top of the extension plate B14 and extends downwards. The surface of the rotating rod 11 is rotatably connected to the inner wall of the extension plate B14. A knob 10 is fixedly connected to the top end of the rotating rod 11. By rotating the knob 10, the winding wheel 12 can be controlled to rewind. Rope 17 is released, which causes the arc-shaped positioning plate 15 to slide within the arc-shaped groove 16, thereby achieving the positioning and release of the nickel bag. A winding wheel 12 is fixedly connected to the surface of the rotating rod 11, and rope 17 is wound around and fixedly connected to the surface of the winding wheel 12. An arc-shaped groove 16 is provided on the left side of the fixing block 6. The inner wall of the arc-shaped groove 16 contacts two arc-shaped positioning plates 15 respectively. By rotating the rotating rod 11, the winding wheel 12 can wind up and unwind rope 17, thereby causing the arc-shaped positioning plate 15 to slide within the arc-shaped groove 16.

[0028] Reference Figure 3 - Figure 5A limiting block 20 is fixedly connected to one side of the arc-shaped positioning plate 15. A limiting groove 21 is formed on the inner wall of the arc-shaped groove 16. The outer wall of the limiting block 20 is slidably connected to the inner wall of the limiting groove 21 to limit the sliding direction of the arc-shaped positioning plate 15, ensuring that the arc-shaped positioning plate 15 slides smoothly in the arc-shaped groove 16 and preventing the arc-shaped positioning plate 15 from shifting or shaking during the sliding process. The end of the rope 17 moves through the right side of the fixing block 6 and is fixedly connected to the outer wall of the two arc-shaped positioning plates 15 respectively. The end of the rope 17 is Y-shaped. Through the winding and unwinding of the winding wheel 12, the rope 17 drives the arc-shaped positioning plate 15 to slide in the arc-shaped groove 16. To achieve the positioning and release of the nickel bag, two fixed pulleys 18 are fixedly connected to the inner wall of the fixing block 6. The surface of the fixed pulleys 18 contacts the surface of the rope 17 to change the direction of movement of the rope 17, ensuring that the rope 17 can move smoothly when pulling the arc-shaped positioning plate 15, avoiding direct friction between the rope 17 and the inner wall of the fixing block 6, and extending the service life of the rope 17. The outer walls of the two arc-shaped positioning plates 15 are elastically connected by springs 19. The elastic force of the springs 19 brings the two arc-shaped positioning plates 15 closer to each other, thereby clamping and positioning the nickel bag. The two ends of the springs 19 are fixedly connected to the outer walls of the two arc-shaped positioning plates 15 respectively.

[0029] Reference Figure 2 The top of the base 7 has two arc-shaped guide grooves 8, which are used to cooperate with the balls 9 at the bottom of the extrusion block 5 to guide the extrusion block 5 to move smoothly and prevent the extrusion block 5 from shaking or deviating during the movement. The bottom of the extrusion block 5 is fixedly connected to two balls 9, which play the role of rolling support and guidance, reduce the friction between the extrusion block 5 and the base 7, and ensure that the extrusion block 5 moves smoothly. The balls 9 at the bottom of the extrusion block 5 are slidably connected to the inner wall of the arc-shaped guide grooves 8.

[0030] Working principle: First, turn knob 10, which drives the rotating rod 11 to rotate. The winding wheel 12 on the surface of the rotating rod 11 rotates accordingly. The winding wheel 12 takes up or releases the rope 17. Since the end of the rope 17 is Y-shaped and is fixedly connected to the outer wall of the two arc-shaped positioning plates 15 respectively, the movement of the rope 17 will cause the two arc-shaped positioning plates 15 to slide on the inner wall of the arc-shaped groove 16. A limit block 20 is fixedly connected to one side of the arc-shaped positioning plate 15. The outer wall of the limit block 20 is slidably connected to the limit groove 21 on the inner wall of the arc-shaped groove 16. This makes the arc-shaped positioning plate 15 always stable during the sliding process. By adjusting knob 10, the two arc-shaped positioning plates 15 are moved away from each other, freeing up space for the nickel pouch.

[0031] Placement and initial positioning of the nickel bladder: Place the nickel bladder in the semi-circular groove of the fixing block 6. At this time, release the knob 10. The two arc-shaped positioning plates 15 approach each other under the elastic force of the spring 19. The two ends of the spring 19 are fixedly connected to the outer walls of the two arc-shaped positioning plates 15 respectively, thus providing stable elastic force to the arc-shaped positioning plates 15. The inner wall of the arc-shaped positioning plate 15 contacts the nickel bladder, thereby initially positioning the nickel bladder and ensuring that the nickel bladder will not shift during the subsequent pressing process.

[0032] Nickel bladder compression: The cylinder 4 is activated, and the cylinder push rod, slidably connected to the inner wall of the cylinder 4, begins to move. The end of the cylinder push rod is fixedly connected to the left side of the extrusion block 5. Therefore, the movement of the cylinder push rod will cause the extrusion block 5 to move to the right. A semi-circular protrusion is fixedly connected to the right side of the extrusion block 5. A semi-circular groove is opened on the left side of the fixed block 6, and the semi-circular protrusion matches the semi-circular groove. When the extrusion block 5 moves to the right, the semi-circular protrusion gradually enters the semi-circular groove, applying pressure to the nickel bladder. Two ball bearings 9 are fixedly connected to the bottom of the extrusion block 5, and two arc-shaped guide grooves 8 are respectively opened on the top of the base 7. The ball bearings 9 are slidably connected to the inner wall of the arc-shaped guide grooves 8. The ball bearings 9 slide within the arc-shaped guide grooves 8, ensuring that the extrusion block 5 remains stable during movement, avoiding uneven compression of the nickel bladder due to the shaking of the extrusion block 5. Finally, through the push of the cylinder push rod, the extrusion block 5 compresses the nickel bladder, thereby expelling the air from the nickel bladder and completing the nickel bladder compression operation.

[0033] Testing and subsequent operations: After the nickel bladder is compressed, the nitrogen and oxygen analyzer can be used for testing. After the test is completed, the above steps are reversed. First, the compression block 5 is released from the nickel bladder by retracting the cylinder push rod. Then, the arc-shaped positioning plates 15 are moved away from each other by rotating the knob 10. The nickel bladder is then removed, and the entire usage process is completed.

[0034] 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.
