[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] Reference Figures 1 to 6 The utility model provides an air quality sensor fixing bracket, comprising a first bracket 1, a fixing slot 4 is provided on the upper part of one side of the first bracket 1, a second bracket 2 is provided on the lower side of the fixing slot 4, the height of the first bracket 1 is consistent with the height of the second bracket 2 and the fixing slot 4, the lower end of the second bracket 2 is rotatably connected to the lower end of the first bracket 1, that is, a second rotating shaft 6 is provided on the bottom of the first bracket 1 close to the second bracket 2, and the first bracket 1 and the second bracket 2 are rotatably connected via the second rotating shaft 6. In this embodiment, the first bracket 1 and the second bracket 2 can also be connected by a rotatable hinged support, so that the first bracket 1 and the second bracket 2 can rotate relative to each other within a certain range, and the angle between the first bracket 1 and the second bracket 2 can be adjusted while also having a certain supporting force. At this time, the rotating hinged support connection can increase the range of the angle that can be supported between the first bracket 1 and the second bracket 2. When the mass of the air quality sensor 8 is relatively small, it can be supported by only the first bracket 1 and the second bracket 2, and the third bracket 3 rotates together with the second bracket 2 to play the role of base support.

[0026] A third bracket 3 is mounted within the second bracket 2. The centers of both sides of the second bracket 2 are pivotally connected to the third bracket 3. A bump 301 is located on the top of the third bracket 3. A first rotation axis 5 is located within the crossbar of the third bracket 3 on the side opposite the bump 301. The third bracket 3 is pivotally connected to the second bracket 2 via the first rotation axis 5, which is parallel to the second rotation axis 6. The lower portion of the first bracket 1 is provided with a plurality of support holes 101 aligned with the bumps 301. In this embodiment, there are five support holes 101. The second bracket 2 can rotate about the second rotation axis 6 so that an angle is formed between the second bracket 2 and the first bracket 1. The third bracket 3 can rotate about the first rotation axis 5 toward the side of the first bracket 1 so that an angle can be formed between the third bracket 3 and the second bracket 2. The protrusion 301 on the third bracket 3 is inserted into the support hole 101. Inserting different support holes 101 can make the angle between the first bracket 1 and the second bracket 2 different. A stable triangular structure is formed between the first bracket 1, the second bracket 2 and the third bracket 3 to support the installed air quality sensor 8. In this embodiment, the angle formed between the first bracket 1 and the second bracket 2 by inserting the protrusion 301 of the third bracket 3 into the support hole 101 ranges from 30° to 60°. The angle between the first bracket 1 and the second bracket 2 formed between each two adjacent support holes 101 differs by 7.5°. In this embodiment, the middle support hole 101 is preferably used so that the angle formed between the first bracket 1 and the second bracket 2 is 45°.

[0027] In order to better implement this utility model, refer to Figure 3 In one embodiment, the first bracket 1 and the second bracket 2 are connected via a fixing assembly 9. The fixing assembly 9 includes a buckle 901 mounted on the side of the first bracket 1 near the second bracket 2. The buckle 901 engages with a slot 902 provided on the second bracket 2. In this embodiment, the slot 902 is preferably provided at the top of the second bracket 2. When the first bracket 1 and the second bracket 2 do not need to be separated, the slot 902 on the second bracket 2 engages with the buckle 901 on the side of the first bracket 1 near the second bracket 2 to secure the second bracket 2, allowing the second bracket 2 to fit snugly against the first bracket 1, facilitating the subsequent installation of the power plug 11.

[0028] In order to better implement this utility model, refer to Figures 1 to 4In one embodiment, the fixed slot 4 opens downward, and a protruding strip 401 is provided on the inner side of the open end of the fixed slot 4 away from the first bracket 1. The power plug 11 is installed in the fixed slot 4, and the power plug 11 moves upward from the bottom of the fixed slot 4 into the fixed slot 4. The power plug 11 is confined in the fixed slot 4 by the protruding strip 401 provided on the inner side of the fixed slot 4. The thickness of the power plug 11 is consistent with the distance from the side of the first bracket 1 close to the fixed slot 4 to the protruding strip 401. In this embodiment, there is a 0.5mm groove on the power plug 11, which facilitates the protruding strip 401 to fix the power plug on the fixed bracket. When the fixed bracket is folded for use, the fixed bracket equipped with the air quality sensor 8 can be installed on the power socket as a whole through the power plug 11, and it can be plugged in and out when used, without the need for drilling holes in the wall or other installation conditions.

[0029] The entire fixing bracket can be made of aluminum alloy, stainless steel or reinforced plastic to resist daily wear and tear and extend its service life; or it can be formed by 3D printing to adapt to power plugs 11 of different sizes in actual use.

[0030] In order to better implement this utility model, refer to Figures 1 to 4 In one embodiment, a through hole 102 is provided on the first bracket 1 within the fixing slot 4. Through hole 102 allows passage of the power cord, facilitating a smooth electrical connection between the power plug 11 and the air quality sensor 8. To accommodate different air quality sensors 8, the number and size of through holes 102 can be adjusted as needed.

[0031] In order to better implement this utility model, refer to Figure 5 In one embodiment, a mounting groove 201 is provided on the upper cross bar of the second bracket 2 , and the mounting groove 201 is close to one side of the first bracket 1 , and the mounting groove 201 is used to accommodate the protrusion 301 .

[0032] In order to better implement this utility model, refer to Figures 1 to 3 In one embodiment, the width of the first bracket 1 is consistent with the width of the second bracket 2 .

[0033] In order to better implement this utility model, refer to Figures 1 to 4 In one embodiment, the first bracket 1 is provided with at least three fixing holes 7 for mounting bolts. A base 10 is mounted on the side of the first bracket 1 away from the fixing slot 4. The base 10 is mounted on the first bracket 1 via bolts installed in the fixing holes 7. The air quality sensor 8 is mounted on the side of the mounting base 10 away from the first bracket 1. The small holes in the first bracket 1 are used to reduce the contact area between the first bracket 1 and the mounting base 10, facilitating heat dissipation of the air quality sensor 8 during use.

[0034] In order to better implement this utility model, refer to Figure 5In one embodiment, a groove is provided on the side of the second bracket 2 away from the mounting groove 201. The groove can be adapted to the protrusion on the placement plane when the fixed bracket is unfolded, thereby preventing the fixed bracket from sliding on the placement plane, thereby affecting the measurement data.

[0035] In order to prevent the fixed bracket from sliding on the placement plane when used in the unfolded state, a layer of anti-slip material is provided on the side of the second bracket 2 away from the mounting groove 201. The anti-slip material can be a silicone pad to increase the friction of the contact surface. At the same time, it is necessary to ensure that the second bracket 2 has sufficient weight during production to prevent the fixed bracket from tipping over.

[0036] In order to improve the stability of the fixed bracket, the contact area between the second bracket 2 and the placement plane can also be increased. Specifically, the second bracket 2 is set as a complete plate surface, and only an inner cavity that can accommodate the third bracket 3 is hollowed out inside without affecting the rotation of the third bracket 3.

[0037] Regardless of whether grooves are provided on the second bracket 2 or anti-slip materials are provided or the contact surface is increased, these three methods can be combined with each other to improve the stability of the fixed bracket.

[0038] Based on the above-mentioned air quality sensor fixing bracket, its working principle is as follows:

[0039] When the fixed bracket is in the closed state, the base 10 of the air quality sensor 8 is installed on the side of the first bracket 1 away from the second bracket 2 through the bolts installed in the fixing hole 7. The buckle 901 cooperates with the slot 902 to make the second bracket 2 fit with the first bracket 1. At this time, the protrusion 301 of the third bracket 3 is in the installation slot 201 of the second bracket 2. Move the power plug 11 from the lower side of the fixed slot 4 upward into the fixed slot 4, and insert the power plug 11 into the power socket to achieve the installation of the air quality sensor 8.

[0040] When the fixed bracket is in the unfolded state, the bottom of the air quality sensor 8 needs to be flush with the bottom of the first bracket 1 during installation. The second bracket 2 is rotated along the second rotation axis 6 to form an angle between the second bracket 2 and the first bracket 1. The third bracket 3 is rotated around the first rotation axis 5, and the protrusion 301 on the third bracket 3 is placed into the support hole 101. According to actual needs, the position of the support hole 101 where the protrusion 301 is placed is adjusted to adjust the inclination of the first bracket 1. Similarly, the air quality sensor 8 is installed on the surface of the first bracket 1. The power plug 11 is directly connected to the power socket. The power plug 11 and the air quality sensor 8 are electrically connected. The unfolded fixed bracket is placed on the plane of the position to be measured.

[0041] While the present invention has been described with reference to preferred embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist. The present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
