[0045] The utility model provides an adjustable sensor bracket for sensor installation. The utility model does not limit the type of sensor, but the structure of the adjustable sensor bracket is particularly suitable for smart home and Internet of Things detection.

[0046] In general, the adjustable sensor bracket proposed in the utility model mainly includes a central shaft 3, a double-ended threaded rod 2, a thrust ball bearing 8, a compression spring 7 and a threaded sleeve 1. Figure 1 , which shows the arrangement relationship among the central shaft 3, the double-start threaded rod 2, the thrust ball bearing 8, the compression spring 7 and the threaded sleeve 1.

[0047] In order to achieve the purpose of flexibly and accurately adjusting the installation position of the sensor, the problem in the background technology that not all modular sensors in smart homes can meet the home design and the position of the sensor cannot be adjusted according to the specific needs of the home environment, resulting in the detection accuracy or range of the sensor being limited; in addition, the Internet of Things detection should also be easy to install and adjust, but the existing sensor bracket cannot achieve flexible adjustability. For this reason, in the technical solution provided in this embodiment, the central axis 3, the double-headed threaded rod 2, and the threaded sleeve 1 are mutually fitted and matched, and the central axis 3 moves in the double-headed threaded rod 2 to achieve coarse control of the sensor distance, and the relative distance with the double-headed threaded rod 2 is accurately adjusted by rotating the threaded sleeve 1, thereby achieving the effect of effectively controlling the installation position of the sensor by using the bracket, and the installation is simple, the control is fine, and it is convenient to observe.

[0048] Combined with Figure 1 and Figure 2 As shown, the central axis 3 is arranged horizontally, and one axial end, that is, the front end 34, is used to install the sensor, and the part of the central axis 3 close to the sensor is sleeved in the double-headed threaded rod 2. When in use, the central axis 3 moves axially along the through hole in the double-headed threaded rod 2 to adjust the position of the sensor installed at the front end 34, thereby achieving the purpose of coarse adjustment of the sensor installation position.

[0049] On this basis, in order to ensure the stability of the central axis 3 during its movement and the consistency of direction, on the one hand, the central axis 3 is provided with a structure including a tail end 31, a limit end 32, a guide end 33 and a front end 34 arranged in sequence along the axial direction, and a front end threaded hole 35 is preset on the side of the front end 34 facing the guide end 33 corresponding to the installation of the sensor, and correspondingly, a limit groove 36 for installing the sensor is also provided on the outer circumference of the front end 34, wherein the front end 34 is used to install the sensor, and the guide end 33 is used to be installed and moved in the double-headed threaded rod 2, wherein the outer diameter of the limit end 32 is much larger than the outer diameters of the tail end 31 and the guide end 33 in order to cooperate with the setting of the thrust ball bearing 8, and also to prevent the central axis 3 from excessively moving, exceeding the moving range set inside the double-headed threaded rod 2, and preventing the sensor from moving beyond the position of the threaded sleeve 1;

[0050] On this basis, the thrust ball bearing 8 is sleeved on the side of the central shaft 3 and the double-headed threaded rod 2 away from the front end 34 of the central shaft 3. The setting of the thrust ball bearing can reduce friction, so that the central shaft 3 can achieve stable and high-speed operation while bearing axial load; similarly, a compression spring 7 is sleeved between the thrust ball bearing 8 and the inner ring 24 of the double-headed threaded rod 2. When the central shaft 3 is subjected to external thrust or vibration, the compression spring 7 can absorb the impact energy and reduce vibration. The buffering effect helps to protect the stability and reliability of the entire bracket;

[0051] On the other hand, it should be specifically explained that, in consideration of the stable movement of the coordinated central shaft 3, the thrust ball bearing 8 and the compression spring 7, the double-threaded rod 2 provided in this embodiment is provided with a structure in which a large diameter section 21 and a small diameter section 22 are integrally provided along the direction close to the sensor. In order to provide an abutment area for the compression spring 7, an inner ring 24 is sleeved inside the small diameter section 22, and the end of the inner ring 24 close to the sensor is flush with the small diameter section 22; in addition, a groove 23 for mounting the nut 4 is provided on the outer circumference of the large diameter section 21. When the nut 4 is tightened on the double-threaded rod 2, the distance between the double-threaded rods 2 can be compressed, thereby limiting the moving position of the central shaft 3 and achieving the purpose of fixed coarse adjustment;

[0052] In terms of the internal structure, a large diameter hole 25 is provided in the large diameter section 21 to facilitate the axial movement of the thrust ball bearing 8 along the inner wall of the large diameter hole 25. A small diameter hole 26 is provided in the small diameter section 22, and one end of the small diameter hole 26 extends into the large diameter section 21, so that the compression spring 7 can be set between the large diameter hole 25 and the small diameter hole 26.

[0053] As mentioned above, a threaded sleeve 1 is threadedly installed on the outer side of the double-threaded rod 2 near the front end 34 of the central axis 3, and the threaded sleeve 1 can achieve fine adjustment of the distance between it and the double-threaded rod 2, that is, fine adjustment of the installation position of the sensor. Therefore, in terms of structure, the threaded sleeve 1 is integrally provided with a threaded installation end 11, a transition end 12 and a protective cover 13 with increasing outer diameters in sequence along the axial direction. During installation, the threaded installation end 11 is provided with an internal thread and installed on the small diameter section 22 of the double-threaded rod 2, but the outer diameter of the threaded installation end 11 is smaller than that of the large diameter section 21. The outer diameter can prevent the installation position from being offset due to excessive rotation, and the protective cover 13 is arranged on the outside of the sensor; when in use, since the length of the threaded sleeve 1 is much larger than the length of the small diameter section 22 of the double-headed threaded rod 2, it can also ensure that the sensor is protected in the threaded sleeve 1. In addition, corresponding to the circumference of the sensor, annular notches 14 arranged at equal intervals are arranged on the protective cover 13, and the width of the notches 14 is larger than the radius of the protective cover 13. The notches 14 can be used to conveniently observe the real-time status of the sensor, and it can also be conveniently cleaned after a period of use.

[0054] Preferably, an outer knurling 15 is integrally extended on the outer circumference of the threaded mounting end 11, and the knurling 15 can cooperate with a rotating tool to achieve high-speed rotation adjustment, or even automatic adjustment, to avoid slippage.

[0055] like Figure 1 and 2 As shown, a gasket 5 and a C-shaped elastic retaining ring 6 are sequentially arranged on one side of the double-ended threaded rod 2 near the front end 34 where the sensor is installed to fill the tiny gap between the connecting parts and form a tightening effect, making the connection of the sensor more firm and stable.

[0056] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
