For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The present invention is described in detail below with reference to the accompanying drawings and in combination with embodiments:

[0029] Example 1

[0030] Since the pyrolytic particle tester is suspended on the ceiling, the lower surface of the tester body is provided with an air inlet, and the air inlet faces downward. The air inlet of the suspended pyrolytic particle tester is more effective for the tester body to inhale test air. Therefore, the current installation process of the pyrolytic particle tester generally uses bolts to fix the pyrolytic particle tester on the ceiling. When the tester needs to be replaced or cleaned, it is necessary to use tools to remove the bolts and take it down. It is very inconvenient to frequently remove the bolts with tools.

[0031] Therefore, the utility model provides a pyrolysis particle tester that is easy to install. When the mounting base 1 is installed on the ceiling, the fixing blocks 4 on both sides of the bottom plate 3 can be movably connected in the groove through the guide grooves 112. The tester body 2 is rotated to the baffle 5, and the tester body 2 is downward to make the fixing blocks 4 engage with the fixing grooves 6. Then, the tester body 2 is engaged with the mounting base 1. The installation process is very convenient and easy to operate.

[0032] Furthermore, the tester body 2 can be removed from the mounting base 1 by pressing the tester body 2 upward and rotating it in the opposite direction, so that the tester body 2 can be easily replaced or cleaned.

[0033] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a pyrolysis particle tester that is easy to install includes a mounting base 1 and a tester body 2 located below the mounting base 1, the mounting base 1 is used to be installed on a suspended ceiling, the mounting base 1 includes an annular fixing portion 11 extending toward the tester body 2, the lower end of the tester body 2 is provided with a bottom plate 3 opposite to the annular fixing portion 11, and the central axis of the bottom plate 3 is the same as the central axis of the annular fixing portion 11, the outer side of the bottom plate 3 is symmetrically provided with a fixing block 4, the upper end of the annular fixing portion 11 is symmetrically provided with a guide groove 112 corresponding to the fixing block 4, the inner side of the annular fixing portion 11 is provided with an annular groove 111 extending circumferentially around the central axis of the annular fixing portion 11, the opening of the annular groove 111 faces the central axis of the annular fixing portion 11, the guide groove 112 is connected to the annular groove 111, and the fixing block 4 is embedded in the guide groove 112 and slides circumferentially in the annular groove 111.

[0034] Preferably, the annular groove 111 includes an upper inner side surface parallel to the bottom plate 3 and a lower inner side surface parallel to the bottom plate 3, the upper inner side surface is located above the lower inner side surface, and the lower inner side surface is provided with a fixing groove 6 which is recessed downward, and the fixing groove 6 is connected to the fixing block 4, and the fixing block 4 is fully embedded in the fixing groove 6.

[0035] Preferably, the horizontal plane where the bottom surface of the fixing groove 6 is located is located above the horizontal plane where the guide groove 112 is located, the inner side of the fixing groove 6 is connected to the lower inner side surface, and the outer side of the fixing groove 6 is connected to the inner side of the annular fixing portion 11.

[0036] Preferably, the outer side of the guide groove 112 is connected to the upper end of the annular fixing portion 11 , the upper end of the annular fixing portion 11 faces the tester body 2 located below, and the inner side of the guide groove 112 is connected to the lower inner side surface.

[0037] Specifically, the fixing groove 6 and the guide groove 112 are both arranged on the side facing the tester body 2. The difference is that the guide groove 112 is intended to allow the fixing block 4 to enter the annular groove 111, so the guide groove 112 is open downward, and the fixing groove 6 is intended to fix the position of the fixing block 4 located in the annular groove 111, so the fixing groove 6 is open upward, so that after the fixing block 4 from below the guide groove 112 enters the annular groove 111 through the guide groove 112, the fixing block 4 then enters downward into the fixing groove 6, but the fixing groove 6 is not open downward, so the fixing block 4 can be placed in the fixing groove 6.

[0038] Preferably, a baffle plate 5 is symmetrically arranged in the annular groove 111 , and two ends of the baffle plate 5 are respectively connected to the upper inner side surface and the lower inner side surface, and the baffle plate 5 is located beside the fixing groove 6 . Specifically, the baffle 5 is used to limit the fixed block 4 and to remind the staff of the installation position of the tester body 2. Therefore, when the fixed block 4 is blocked by the baffle 5 and cannot rotate, it means that the tester body 2 has been rotated to the installation position. Specifically, since the fixed block 4 in this embodiment is rotatably installed and the fixed block 4 is symmetrically arranged, the baffle 5 is also symmetrically arranged as a left baffle 5 and a right baffle 5. The fixing grooves 6 beside the two baffles 5 are respectively on different surfaces. For example, the rear end surface of the left baffle 5 is provided with a fixing groove 6, and the front end surface of the right baffle 5 is provided with a fixing groove 6. Therefore, when rotating clockwise, one fixed block 4 rotates from the front end surface of the left baffle 5 to the front end surface of the right baffle 5, and the other fixed block 4 rotates from the rear end surface of the right baffle 5 to the rear end surface of the left baffle 5, and then is pulled down at the same time, so that the two fixed blocks 4 fall into the corresponding fixing grooves 6 for fixing. Among them, the guide groove 112 is located on the left and right sides of the fixing groove 6.

[0039] Preferably, the length of the fixing block 4 extends circumferentially around the central axis of the base plate 3, the width of the fixing block 4 extends horizontally toward the outside of the base plate 3, the length of the guide groove 112 extends circumferentially around the central axis of the annular fixing portion 11, the width of the guide groove 112 extends horizontally toward the outside of the annular fixing portion 11, the length of the fixing block 4 is less than or equal to the length of the guide groove 112, and the width of the fixing block 4 is less than or equal to the width of the guide groove 112.

[0040] Preferably, the depth of the annular groove 111 in the horizontal direction is greater than or equal to the width of the fixing block 4 , and the height of the annular groove 111 in the vertical direction is greater than or equal to the height of the fixing block 4 .

[0041] Preferably, the mounting base 1 further comprises a base 12, which is fixedly connected to the lower end of the annular fixing portion 11, and the base 12 is used to install the mounting base 1 on the ceiling. The mounting base 1 does not need to be disassembled, and only the tester body 2 needs to be disassembled.

[0042] Preferably, the base 12 is provided with a sleeve 121 extending toward the tester body 2, the central axis of the sleeve 121 is the same as the central axis of the annular fixing portion 11, and the bottom plate 3 is provided with a guide portion 7 corresponding to the sleeve 121, the guide portion 7 is embedded in the sleeve 121, and the sleeve 121 is filled with an elastic soft block.

[0043] Preferably, the horizontal plane where the upper end of the sleeve 121 is located is above the horizontal plane where the upper end of the annular fixing portion 11 is located, and the height of the guide portion 7 is greater than the height of the sleeve 121. Specifically, the sleeve 121 does not exceed the height of the annular fixing portion 11, and the height of the guide portion 7 can be greater than the height of the sleeve 121. In addition, in order to reduce the effect of vibration on the tester body 2, the utility model can also fill an elastic soft block in the sleeve 121. The elastic soft block can be compressed when the guide portion 7 is inserted into the sleeve 121, and the elastic soft block can also rebound when the guide portion 7 moves downward out of the sleeve 121, so that the elastic soft block is connected to the guide portion 7, which can not only increase the connectivity between the mounting base 1 and the tester body 2, but also play a role in shock absorbing the tester body 2. Among them, the elastic soft block can be a silicone block.

[0044] The specific working principle is as follows: the mounting base 1 is fixedly mounted on the ceiling, and the fixing block 4 of the tester body 2 is aligned with the guide hole according to the guide groove 112 set at the upper end of the mounting base 1, and the tester body 2 is pressed upward to embed the tester body 2 into the mounting base 1. The fixing block 4 is accommodated in the annular groove 111 through the corresponding guide hole, and through the corresponding relationship between the guide portion 7 and the sleeve 121, while the tester body 2 is pressed upward, the guide portion 7 is also squeezed upward into the sleeve 121, and the elastic soft block in the sleeve 121 is compressed, such as Figure 5 shown.

[0045] Then, rotate the tester body 2 in the positive direction to the installation position, that is, when the fixing block 4 is rotated close to the baffle 5, the position of the baffle 5 is the installation position, and then pull the tester body 2 downward to make the fixing block 4 of the tester body 2 embedded in the fixing groove 6. Since the fixing groove 6 and the fixing block 4 are the same size, the fixing block 4 can be stably fixed in the fixing groove 6, and while pulling the tester body downward, the guide portion 7 moves downward out of the sleeve 121, but part of the guide portion 7 is still located in the sleeve 121, then the elastic soft block in the sleeve 121 will generate a rebound force, and the rebound force will generate a downward thrust on the fixing block 4, and the thrust can stably fix the fixing block 4 in the fixing groove 6. Figure 6 shown.

[0046] Then, by pressing upward to push the fixing block 4 out of the fixing groove 6, the tester body 2 is rotated in the opposite direction, so that the fixing block 4 can be turned to the corresponding position of the guide groove 112, and then the tester body 2 can be pulled downward to remove the tester body 2 from the mounting base 1. The installation and disassembly processes do not require too many complicated steps, and can be achieved by simply rotating, pushing and pulling, which is convenient for the staff to replace or clean the tester body 2.

[0047] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
