The sleeve 1 is hollow cylindrical. The two ends of the sleeve 1 are respectively provided with internal threads. A partition 7 is arranged on the inner side of the sleeve 1, and the partition 7 is located between the two internal threads. The middle of the partition plate 7 is provided with a mounting hole for mounting the sensor 4 or the functional circuit, two sides of the partition plate 7 are respectively provided with an annular convex inclined plane sealing structure 8, the diameter of the outer side surface of each convex inclined plane sealing structure 8 is gradually reduced along the direction far away from the partition plate 7, and the outer side surface of each convex inclined plane sealing structure 8 is a sealing surface.
The protective cover 2 is a semi-closed shell with an opening, and an external thread matched with the internal thread is arranged on the outer side of the opening end of the protective cover 2. An annular concave inclined plane sealing structure 9 is arranged on the inner side of the opening end of the protective cover 2, the diameter of the inner side face of the concave inclined plane sealing structure 9 is gradually reduced along the direction away from the opening, and the inner side face of the concave inclined plane sealing structure 9 is a sealing face. Two protective covers 2 are arranged, the two protective covers 2 are respectively screwed at two ends of the sleeve 1, and after the two protective covers are screwed, the convex inclined plane sealing structure 8 and the concave inclined plane sealing structure 9 are matched to seal a gap between the sleeve 1 and the protective covers 2. In the present embodiment, the protective cover 2 is in the form of a half capsule, and two protective covers 2 and a sleeve 1 constitute a capsule-shaped shell for protecting the sensor 4 and the functional circuit therein.
The mounting plate 3 is circular, and is matched with the mounting holes of the partition plate 7 and the partition plate 7, the edge of the mounting plate 3 is fixed at the edge of the mounting hole of the partition plate 7, and the mounting plate 3 and the partition plate 7 are fixed through screws or gluing.
The sensor 4 is fixed on one side of the mounting plate 3, the functional circuit is fixed on the other side of the mounting plate 3, and the sensor 4 is electrically connected with the functional circuit.
The functional circuit comprises an antenna 6, a main control circuit and a micro battery 5, wherein the antenna 6 is electrically connected with the main control circuit, the main control circuit is electrically connected with the micro battery 5, and the sensor 4 is electrically connected with the main control circuit.
In this embodiment, the sensor 4 and the functional circuit are both prior art or prior art products. Wherein, sensor 4 is detachable with main control circuit and is connected, can change sensor 4 at will according to actual demand, satisfies the demand of different application scenes. In the present embodiment, the main control circuit is integrated with the micro battery 5 into a unitary structure.
The wireless sensor that this embodiment provided, two safety covers 2 are fixed respectively at sleeve pipe 1's both ends, in the fixed process, the medial surface of the concave inclined plane seal structure 9 of safety cover 2 contacts and extrudes with the lateral surface of sleeve pipe 1's convex inclined plane seal structure 8, form seal structure, two safety covers 2 constitute the shell of a completion with sleeve pipe 1, protect inside sensor 4 and functional circuit etc., and effectively dustproof and waterproof, reach effective sealed effect, compare with the sealed seal structure of current utilization sealing washer, the assembly degree of difficulty has been reduced, and the cost of sealing washer has been saved. In addition, in this embodiment, the protective cover 2 and the sleeve 1 are connected by screw threads, so that the assembly is convenient.
In the process of screwing the protective cover 2 into the sleeve 1, the outer side surface of the convex inclined surface sealing structure 8 is in direct contact with the inner side surface of the concave inclined surface sealing structure 9 to form a surface-surface contact sealing mode. If the outer side surface of the convex inclined plane sealing structure 8 and the inner side surface of the concave inclined plane sealing structure 9 form a narrow contact surface, and the narrow contact surface is a narrow surface sealing form, the requirement on the processing precision can be reduced, and the sealing effect is further effectively improved. Therefore, the slopes of the outer side surface of the male bevel seal structure 8 and the inner side surface of the female bevel seal structure 9 are slightly different so that a narrow surface seal is formed when the outer side surface of the male bevel seal structure 8 and the inner side surface of the female bevel seal structure 9 are pressed against each other. For example: the maximum diameter of the outer side surface of the convex inclined surface sealing structure 8 is larger than the maximum diameter of the inner side surface of the concave inclined surface sealing structure 9, and the minimum diameter of the outer side surface of the convex inclined surface sealing structure 8 is smaller than the minimum diameter of the inner side surface of the concave inclined surface sealing structure 9.

Through the two modes, the slopes of the outer side surface of the convex inclined surface sealing structure 8 and the inner side surface of the concave inclined surface sealing structure 9 are different, and after screwing, the contact positions of the concave inclined surfaces and the convex inclined surfaces are mutually extruded and slightly deformed to form narrow surface sealing, so that the sealing effect is improved. Because the outer side surface of the convex bevel sealing structure 8 is matched with the inner side surface of the concave bevel sealing structure 9, the minimum diameter of the outer side surface of the convex bevel sealing structure 8 is smaller than the maximum diameter of the inner side surface of the concave bevel sealing structure 9.
In this embodiment, the two protective covers 2 may be the same size, or may have different lengths, different sizes, and different shapes to accommodate different types of sensors 4 and different functional circuits. The functional circuitry and the location of the sensor 4 can be at either end.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
