Description

Technical Field

[0001] The utility model relates to the technical field of gas analysis equipment, and more specifically, the utility model relates to a combined gas analysis device. Background Art

[0002] Gas analysis is an analytical method for determining the composition of a mixed gas by utilizing the differences in the physical and chemical properties of various gases. According to the measurement principle, it can be divided into two categories: chemical and physical methods, and there are corresponding test instruments. Staff often use a combined gas analysis device to analyze and detect gases. Although the existing gas analysis device can facilitate the staff's gas analysis work, however, in actual use, a dehumidification plate is generally provided inside the existing gas analysis device to remove moisture in the gas. However, the dehumidification plate is generally fixedly installed inside the gas analysis device by bolts. When the dehumidification plate needs to be replaced after long-term use, the staff often needs to disassemble the outer shell of the gas analysis device and then remove the bolts fixing the dehumidification plate before it can be replaced. This method is cumbersome to operate and has low replacement efficiency. Therefore, it needs to be improved. Content of the Utility Model

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figures 1 to 5 shown, the present utility model provides a combined gas analysis device, including:

[0028] An analyzer 1, and an air inlet pipe 2 is fixedly installed in the middle of the right end of the analyzer 1;

[0029] A limiting mechanism, which is arranged above the air inlet pipe 2;

[0030] A protection mechanism, which is arranged behind the analyzer 1;

[0031] Among them, the limiting mechanism includes a fixed block 5, which is fixedly installed at the right end of the top of the intake pipe 2. The left side of the top end of the inner wall of the fixed block 5 is rotatably connected to a round shaft 6. The left end of the round shaft 6 is fixedly installed with a stop block 7. An arc-shaped groove 8 is formed in the front of the round shaft 6. The inner wall of the fixed block 5 is movably sleeved with a latch 9 located on the right side of the round shaft 6. The outer surface of the latch 9 is fixedly connected with a slider 10 located inside the arc-shaped groove 8. The top of the latch 9 is fixedly connected with a pull handle 11. The top of the outer surface of the latch 9 is movably sleeved with a spring 12, and the two ends of the spring 12 are respectively fixedly connected to the outer surfaces of the fixed block 5 and the pull handle 11. The latch 9 driving the slider 10 to move upward can cause the round shaft 6 to drive the stop block 7 to rotate.

[0032] By setting the spring 12 in a stretched state, the latch 9 has a tendency to move downward. By pulling the pull handle 11 upward to make the latch 9 move upward and stretch the spring 12, the slider 10 can be made to move upward, thereby being able to squeeze the inner wall of the arc-shaped groove 8, and further enabling the round shaft 6 to drive the stop block 7 to rotate.

[0033] Among them, it includes:

[0034] A protection mechanism, which is composed of a first magnet 13, a second magnet 14 and a baffle 15;

[0035] The first magnet 13 is fixedly installed at the top of the back of the analyzer 1. The baffle 15 is hinged in the middle of the back of the analyzer 1. The second magnet 14 is fixedly installed on the inner wall of the baffle 15. The magnetic attraction between the first magnet 13 and the second magnet 14 can keep the baffle 15 at the top of the back of the analyzer 1.

[0036] Through the design of opposite magnetic poles between the first magnet 13 and the second magnet 14, a magnetic adsorption effect can be generated between the first magnet 13 and the second magnet 14, so as to stably keep the baffle 15 at the top of the back of the analyzer 1.

[0037] Among them, heat dissipation holes 16 are formed in the middle of the back of the analyzer 1, and the heat dissipation holes 16 are evenly distributed in the middle of the back of the analyzer 1.

[0038] Through the design of the heat dissipation holes 16, the internal electronic components of the analyzer 1 can dissipate heat well during operation, thus avoiding overheating from affecting normal operation.

[0039] Among them, a handle 17 is fixedly installed in the middle of the top of the analyzer 1, and the appearance of the handle 17 is a semi-circular ring.

[0040] Through the design of the handle 17, it is convenient for the staff to carry the entire analyzer 1.

[0041] Among them, a sheath 18 is fixedly sleeved on the outer surface of the handle 17, and the sheath 18 is made of rubber.

[0042] The soft nature of rubber can make the worker feel more comfortable when holding the sheath 18 and lifting the handle 17 .

[0043] Brackets 19 are fixedly installed on both sides of the bottom of the analyzer 1 , and an anti-slip pad 20 is fixedly connected to the bottom of the bracket 19 .

[0044] The design of the anti-slip pad 20 can effectively prevent the analyzer 1 from slipping when the analyzer 1 is placed on an inclined surface with a small inclination angle.

[0045] Among them, a dehumidification plate body 3 is movably installed in the middle of the inner wall of the air inlet pipe 2, the top of the dehumidification plate body 3 penetrates the air inlet pipe 2 and is fixedly connected with a block 4, and the top of the block 4 is movably connected to the bottom end of the block 7.

[0046] Through the design of the dehumidification plate body 3, moisture in the gas can be effectively removed, thereby improving the analysis and detection accuracy.

[0047] The working principle and use process of this utility model:

[0048] When the analyzer 1 is running, the staff can rotate the second magnet 14 and the baffle 15 to the back of the first magnet 13. Due to the magnetic attraction between the second magnet 14 and the first magnet 13, the baffle 15 will remain on the top of the back of the analyzer 1, and the analyzer 1 dissipates heat outwards through the heat dissipation holes 16. When the analyzer 1 is idle, the staff can rotate the baffle 15 so that the baffle 15 covers the heat dissipation holes 16, thereby protecting the analyzer 1 and preventing external dust from entering the analyzer 1 through the heat dissipation holes 16 and affecting the heat dissipation of the electronic equipment in the analyzer 1.

[0049] When the staff needs to replace the dehumidifier plate body 3, they can first pull the handle 11 upwards to make the pin 9 move upwards and stretch the spring 12, so that the slider 10 can move upwards and squeeze the inner wall of the arc groove 8, and then the circular shaft 6 can drive the block 7 to rotate. When the block 7 rotates ninety degrees, the limiting effect on the block 4 is released, and the staff can pull the block 4 to extract the dehumidifier plate body 3 from the inside of the air inlet pipe 2 for replacement, which ultimately improves the efficiency of replacing the dehumidifier plate body 3 and makes it convenient for the staff to use.
