Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of formaldehyde detection auxiliary equipment, specifically an auxiliary device for measuring indoor formaldehyde content. Background Technology
[0002] As living standards improve, people are paying more attention to air quality. Formaldehyde is a harmful gas that poses a serious threat to human health. After renovations and decorations are carried out in homes, offices, and other areas, it is necessary to test the formaldehyde concentration in these areas to ensure the normal living and working conditions of the users.
[0003] While traditional portable formaldehyde detectors can detect formaldehyde, they are inconvenient to use because they are operated by hand and it is difficult to detect high places or narrow, hard-to-reach locations. Therefore, this application proposes an auxiliary device for measuring indoor formaldehyde content. Utility Model Content

[0013] (III) Beneficial Effects
[0014] This utility model provides an auxiliary device for measuring indoor formaldehyde content, which has the following beneficial effects:
[0015] 1. In this utility model, the formaldehyde detector can be placed inside the storage frame and locked with bolts. Then, by rotating the drive rod, the driving gear can be rotated, and the driven gear and screw can be rotated synchronously. The screw drives the inner column to move in the vertical direction, thereby adjusting the height of the formaldehyde detector, which is convenient for formaldehyde detection in high places and narrow, hard-to-reach places.
[0016] 2. In this invention, the lower end of the positioning rod can also be threaded into the base, with the base supporting the entire device. This frees up the hands, allowing the device to be placed on the ground for formaldehyde detection in the air. This reduces operator fatigue, especially during prolonged testing. The base provides excellent support, making the device more stable during operation. This avoids errors caused by unstable handling or improper device placement, improving the accuracy of the test results. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Please see Figures 1 to 5 This utility model provides a technical solution: an auxiliary device for measuring indoor formaldehyde content, including an outer rod 1 and a slot 101 opened inside the outer rod 1. The slot 101 is arranged vertically and has an open top. An inner column 7 is slidably inserted inside the slot 101. The top view of the slot 101 is a rectangular structure, which is to limit and guide the inner column 7, ensuring that the inner column 7 can only move vertically. A storage frame 11 is fixedly connected to the upper end of the inner column 7. The storage frame 11 is used to place the formaldehyde detector. A bolt 6 is threaded into the side wall of the storage frame 11. By rotating the bolt 6, the end of the bolt 6 comes into contact with the formaldehyde detector, thereby locking the formaldehyde detector. A screw 4 is rotatably inserted into the bottom wall of the slot 101, and the bottom of the inner column 7 is threaded onto the top of the screw 4.
[0025] A driven gear 5 is coaxially fixedly connected to the screw 4 near the bottom of the slot 101. A through lower opening 102 is opened at the bottom of the slot 101. A support 10 is fixedly connected to the side wall of the outer sleeve 1. A drive rod 9 is rotatably inserted into the support 10. A drive gear 8 is fixedly connected to the lower end of the drive rod 9. The drive gear 8 is meshed with the driven gear 5.
[0026] The formaldehyde detector can be placed inside the storage box 11 and locked with bolt 6. Then, by rotating the drive rod 9, the driving gear 8 will rotate, and the driven gear 5 and screw 4 will rotate synchronously. The screw 4 will drive the inner column 7 to move in the vertical direction, thereby adjusting the height of the formaldehyde detector, making it convenient to detect formaldehyde in high places and narrow, hard-to-reach places.
[0027] An upper opening 103 is provided on the side wall of the outer sleeve rod 1 above the lower opening 102, which facilitates hand operation of the top of the drive rod 9 and increases the operating space.
[0028] It also includes a base 3, and a positioning rod 2 is fixedly connected to the bottom of the outer sleeve rod 1. The lower end of the positioning rod 2 is threaded into the interior of the base 3.
[0029] Alternatively, the lower end of the positioning rod 2 can be threaded into the base 3, which supports the entire device. This frees up the hands, allowing the device to be placed on the ground for formaldehyde detection in the air. This reduces operator fatigue, especially during prolonged testing. The base 3 provides excellent support, making the device more stable during operation. This avoids errors caused by unstable handling or improper device placement, improving the accuracy of the test results.
