Description

Technical Field

[0001] The present invention relates to the technical field of oxygen analyzers, in particular to an oxygen analyzer. Background Art

[0002] The oxygen analyzer is an industrial online process analysis instrument that is widely used to detect the oxygen concentration in mixed gases in heating furnaces, chemical reaction vessels, ground wells, industrial nitrogen production, and other occasions. In industrial production, the oxygen analyzer can be used to monitor and control the oxygen concentration in reactors, combustion systems, air separation oxygen production, chemical processes, etc. in real time to ensure production safety and product quality. In chemical processes, monitoring oxygen concentration can prevent explosions or other safety accidents.

[0003] Existing oxygen analyzers need to connect the oxygen supply pipe to the oxygen analyzer, and the interface of the oxygen analyzer is set on the outer shell of the device. It is easy to cause damage to the device interface during the use of the oxygen analyzer, which can easily cause gas to leak from the interface of the oxygen analyzer, which will cause errors in the detection results. After the oxygen supply pipe is connected, it is necessary to maintain a stable connection between the device and the pipe. However, the existing oxygen analyzer fixes the pipe through the interface, and the interface of the device is prone to loosening after long-term use, which will cause gas leakage at the interface and affect the analysis results.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1-Figure 7 As shown, the oxygen analyzer of the present invention includes a chassis 1, a protective component 2 is provided on the outer wall of the chassis 1, a clamping component 3 is provided inside the protective component 2, a fixing component 4 is provided on the surface of the chassis 1, and a shielding component 5 is provided inside the protective component 2;

[0028] The protection component 2 includes two card blocks 21, which are symmetrically fixedly connected to the outer walls of the chassis 1 on both sides. A U-shaped rod 23 is clamped on the outer wall of the chassis 1, and sliding grooves 22 are provided at both ends of the U-shaped rod 23. The two card blocks 21 are correspondingly slidably connected inside the two sliding grooves 22, and positioning grooves 24 are provided at both ends of the U-shaped rod 23. An opening 25 is provided on one side inner wall of the two positioning grooves 24. Fixed blocks 26 are fixedly connected to the side walls of the chassis 1 on both sides, a cover plate 27 is fixedly connected to the inner wall of the U-shaped rod 23, and grooves 28 are provided on the side walls of both ends of the U-shaped rod 23. Card blocks 29 are fixedly connected to the outer walls of the chassis 1 on both sides, and the two card blocks 29 match the two grooves 28. A connecting groove 210 is provided on the outer wall of the chassis 1, and the connecting groove 2 The U-shaped rod 23 is pulled and slid along the direction of the sliding groove 22, so that the fixing block 26 slides in the positioning groove 24 to a position corresponding to the opening 25, and then the U-shaped rod 23 is pushed and rotated upward around the clamping block 21, and the cover plate 27 is driven to rotate upward by the U-shaped rod 23, so that the cover plate 27 is removed from the surface of the chassis 1, and then the U-shaped rod 23 is pushed and one end of the chassis 1 is lifted up, so that the clamping block 29 is clamped in the groove 28 to fix the U-shaped rod 23, and the bottom of one end of the chassis 1 is supported by the U-shaped rod 23, so that the connecting groove 210 on the chassis 1 is tilted. This makes it convenient to connect the oxygen supply pipe to the tilted joint 211, and the connecting groove 210 is protected by the cover plate 27 to prevent the joint 211 from being damaged.

[0029] The card assembly 3 includes two card interfaces 31, which are symmetrically arranged on the surface of the cover plate 27. The inner side walls of the card interfaces 31 on the side away from each other are fixedly connected with fixed clips 32. The inner side walls of the card interfaces 31 on the side close to each other are each provided with a clip groove 33. The inner walls of the two clip grooves 33 are provided with the same through hole 34. Two push rods 35 are clamped inside the through hole 34. The ends of the two push rods 35 close to the card interfaces 31 are fixedly connected with connecting blocks 36. The ends of the two connecting blocks 36 away from the push rods 35 are fixedly connected with sliding clips 37. The two sliding clips 37 are clamped in the two clip grooves 33. Push blocks 38 are fixedly connected to the surface of the push rods 35. The push block 38 is slidably connected to the inside of the two slide grooves 39. The slide groove 39 is opened on the inner wall of the same through hole 34. The slide groove 39 is connected to the outer wall of the cover plate 27. The two connecting blocks 36 push the two sliding clips 37 to clamp the surface of the oxygen supply pipe. When the cover plate 27 is stuck on the surface of the chassis 1, the sliding clips 37 are driven to move by the cover plate 27. The oxygen supply pipe is fixed to the joint 211 through the sliding clips 37 and the fixed clips 32, and then the cover plate 27 is fixed by the L-shaped plate 43. The force between the oxygen supply pipe and the joint 211 is borne by the U-shaped rod 23. This can ensure that the joint 211 remains sealed to prevent damage to the joint 211 and gas leakage.

[0030] Specifically, the fixing component 4 includes a threaded column 41 and a slot 44. The threaded column 41 is fixedly connected to the upper surface of the chassis 1. A nut 42 is threadedly connected to the threaded surface of the threaded column 41. An L-shaped plate 43 is sleeved on the threaded surface of the threaded column 41. The slot 44 is opened at the upper end of the cover 27. One end of the L-shaped plate 43 is clamped in the inside of the slot 44. The nut 42 is rotated on the surface of the threaded column 41 to move the nut 42 upward, and then the L-shaped plate 43 is pushed up and removed from the slot 44 to release the fixation of the cover 27.

[0031] Specifically, the shielding assembly 5 includes two shielding plates 51 and two slots 54. The shielding plates 51 are correspondingly connected to the inside of the two card interfaces 31. The lower end of the shielding plate 51 is fixedly connected to a fixing bar 52. Both ends of the fixing bar 52 are fixedly connected to an insertion rod 53. The slots 54 are opened at the lower ends of the side walls at both ends of the cover plate 27. The insertion rod 53 is inserted into the two slots 54. Pulling the fixing bar 52 drives the insertion rod 53 to move out of the slot 54, so that the shielding plate 51 is moved out of the card interface 31.

[0032] Specifically, the cover plate 27 corresponds to the connection slot 210 , and the card interface 31 on the cover plate 27 corresponds to the connector 211 . The cover plate 27 protects the connection slot 210 to prevent the connector 211 from being damaged.

[0033] Specifically, the length of the sliding groove 22 is the same as that of the positioning groove 24, and the opening 25 on the positioning groove 24 is in the opposite direction to the groove 28, so that the sliding of the U-shaped rod 23 is restricted by the sliding groove 2 and the positioning groove 24 and remains stable, and when the U-shaped rod 23 rotates upward, it will drive the groove 28 to be stuck on the clamping block 29.

[0034] Specifically, the distance between the clamping block 21 and the clamping block 29 is the same as the distance between the sliding slot 22 and the groove 28 , so that the rotating U-shaped rod 23 drives the groove 28 to be accurately clamped on the clamping block 29 .

[0035] Specifically, the fixed clip 32 corresponds to the sliding clip 37 , and the sliding clip 37 is provided with a concave surface. The fixed clip 32 and the sliding clip 37 can clamp the pipe connected to the joint 211 .

[0036] The U-shaped rod 23 is then pulled up to rotate around the block 21, and the cover 27 is driven to rotate upward by the U-shaped rod 23, so that the cover 27 is removed from the surface of the chassis 1. Then, the U-shaped rod 23 is pushed and one end of the chassis 1 is lifted up, so that the clamping block 29 is clamped in the groove 28 to fix the U-shaped rod 23. The bottom of one end of the chassis 1 is supported by the U-shaped rod 23, so that the connecting groove 210 on the chassis 1 is tilted. This makes it convenient to connect the oxygen supply pipe to the tilted joint 211. The strip 52 drives the insertion rod 53 to move out of the slot 54, so that the baffle 51 is moved out of the card interface 31, and then pushes the U-shaped rod 23 back to make the card interface 31 clamped on the oxygen supply pipe, pushing the two push blocks 38 to drive the two push rods 35 to move, and the two push rods 35 drive the two connecting blocks 36 to move, and the two connecting blocks 36 push the two sliding clips 37 to clamp on the surface of the oxygen supply pipe. When the cover plate 27 is stuck on the surface of the chassis 1, the sliding clip 37 is driven to move by the cover plate 27, and the oxygen supply pipe is fixed to the joint 211 by the sliding clip 37 and the fixed clip 32, and then the cover plate 27 is fixed by the L-shaped plate 43, and the force between the oxygen supply pipe and the joint 211 is borne by the U-shaped rod 23, so that the joint 211 can be kept sealed, thereby preventing the joint 211 from being damaged and causing gas leakage, so that the analysis results can be kept accurate.
