[0002] Airborne bacteria refer to microorganisms such as bacteria and fungi suspended in the air. Their quantity and quality are directly related to air cleanliness and human health. Traditional methods for detecting airborne bacteria mostly involve manual collection and microscopic counting, which are not only cumbersome and time-consuming, but also easily affected by human factors, leading to inaccurate test results. Therefore, automated detection instruments have been developed to detect airborne bacteria.

[0003] Existing automatic airborne bacteria testers are inconvenient to install and adjust, and lack flexibility. Therefore, a new automatic airborne bacteria tester is needed. Utility Model Content

[0006] Preferably, the mounting plate forms a rotating structure with the base via a damping bearing, and the damping bearing has a range of motion of 360°.

[0007] Preferably, the adjusting block forms a rotating structure between the knob and the mounting plate, and the knob and the mounting plate are threaded together.

[0009] Preferably, the spring is installed inside the mounting plate at the connection point with the slide rod, and the slide rod forms a lifting structure with the mounting plate through the spring.

[0010] Preferably, the clamp forms a transmission structure through the movable shaft, the slide rod and the adjusting block, the clamp forms a rotation structure through the fixed shaft and the mounting plate, and the mounting base forms a detachable structure through the clamp and the mounting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting up a locking mechanism, the damping bearing can be flexibly adjusted in angle to easily adapt to different usage angle requirements. It can also be stably connected to the mounting plate and the mounting base through the locking mechanism for clamping and fixing.

[0019] 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.

[0020] Example 1

[0021] like Figure 1-4 As shown in the figure, an automatic tester for airborne bacteria includes a base 1, a damping bearing 2 mounted on the top of the base 1, a mounting plate 3 mounted on the outer side of the damping bearing 2, an adjusting block 4 mounted on the outer side of the mounting plate 3, a knob 5 fixed in the middle of the adjusting block 4, a locking mechanism 6 arranged in a ring around the periphery of the mounting plate 3, a mounting seat 7 mounted on the front side of the mounting plate 3, a test box 8 fixed on the front side of the mounting seat 7, and magnetic suction pieces 9 symmetrically fixed on both sides of the base 1. A connecting bolt 10 passes through the middle of the magnetic suction piece 9 and is fixed to the outer side of the base 1 by the connecting bolt 10.

[0022] The mounting plate 3 forms a rotating structure with the base 1 through the damping bearing 2, and the damping bearing 2 has a range of motion of 360°, which can flexibly adjust the use angle of the equipment to adapt to the installation and use in different positions.

[0023] The adjusting block 4 forms a rotating structure with the mounting plate 3 via the knob 5, and the knob 5 and the mounting plate 3 are threaded together. Rotating the knob 5 on the rear side causes the adjusting block 4 to rotate. The adjusting block 4 adopts an uneven radius setting, which can change the radius of contact with the slide rod 604 as it rotates, thereby pushing the slide rod 604 inward.

[0024] The locking mechanism 6 includes a fixed shaft 601 fixedly disposed with the mounting plate 3. A clip 602 is rotatably connected to the outer side of the fixed shaft 601. A movable shaft 603 extends laterally through the tail end of the clip 602. The top end of a slide rod 604 is rotatably connected to the middle of the movable shaft 603. A spring 605 extends through the outer side of the slide rod 604.

[0025] Spring 605 is installed inside the mounting plate 3 and connected to slide rod 604. Slide rod 604 forms a lifting structure with mounting plate 3 through spring 605. Slide rod 604 can automatically reset through spring 605 to maintain the relaxed state after the clip 602 is released.

[0026] The clamp 602 forms a transmission structure with the movable shaft 603, the slide rod 604 and the adjusting block 4. The clamp 602 forms a rotation structure with the mounting plate 3 with the fixed shaft 601. The mounting base 7 forms a detachable structure with the mounting plate 3 with the clamp 602. In this way, the mounting base 7 installed in the middle of the mounting plate 3 is stably clamped and fixed, and the test box 8 and the mounting plate 3 can be assembled flexibly and quickly. Disassembly does not require the use of tools.

[0027] Working principle: First, the test box 8 can be connected and installed to the mounting plate 3 via the mounting base 7. Rotate the knob 5 on the rear side to make the adjusting block 4 rotate. The adjusting block 4 adopts an uneven radius setting, which can change the radius of contact with the slide rod 604 as it rotates, thereby pushing the slide rod 604 inward. At this time, the movable shaft 603 drives the lifting clamp 602 to lock inward around the fixed shaft 601, thereby stably clamping and fixing the mounting base 7 installed in the middle of the mounting plate 3, and assembling the test box 8 and the mounting plate 3 flexibly and quickly.

[0028] Next, the magnetic absorbing piece 9 is installed on both sides of the base 1 through the connecting bolt 10, which can stably fix the magnetic absorbing piece 9 on the base 1. The base 1 can be fixedly installed on the plane of the detection point by further adding the connecting bolt 10, or the magnetic absorbing piece 9 made of magnetic material can be directly adsorbed onto a suitable iron plane as needed.
