As shown in Figs. 1-5, embodiment 1 provides a kind of wireless sensor comprising casing 1, protective cover 2, mounting plate 3,
Sensor 4 and functional circuit.
Casing 1 is in hollow cylindrical.Internal screw thread is respectively arranged at the both ends of casing 1.Partition is equipped in the inside of casing 1
7, and partition 7 is located between two internal screw threads.The installation for installing sensor 4 or functional circuit is equipped in the centre of partition 7
Hole is respectively provided with an annular convex inclined plane sealing structure 8, the lateral surface diameter edge of convex inclined plane sealing structure 8 in the two sides of partition 7
Direction far from partition 7 gradually becomes smaller, and wherein the lateral surface of convex inclined plane sealing structure 8 is sealing surface.
Protective cover 2 is the semi-closed casings equipped with opening, is equipped with and screw-internal thread fit on the outside of the open end of protective cover 2
External screw thread.The surface seal structure 9 that concaves of annular, the medial surface for the surface seal structure 9 that concaves are equipped on the inside of the open end of protective cover 2
Diameter gradually becomes smaller along the direction far from opening, wherein the medial surface for the surface seal structure 9 that concaves is sealing surface.Protective cover 2 is equipped with
Two, two protective covers 2 are screwed together in the both ends of casing 1 respectively, convex inclined plane sealing structure 8 are made after screwing togather and the surface seal structure that concaves
9 cooperations are with the gap between sealing sleeve pipe 1 and protective cover 2.In the present embodiment, protective cover 2 is in half capsule shape, two protective covers
2 and casing 1 form the shell of a capsule shape, protect internal sensor 4 and functional circuit etc..
Mounting plate 3 is rounded, matches with the mounting hole of partition 7 and partition 7, and the edge of mounting plate 3 is fixed on partition 7
The edge of mounting hole, mounting plate 3 are fixed with partition 7 by screw or gluing.
Sensor 4 is fixed on the side of mounting plate 3, and functional circuit is fixed on the other side of mounting plate 3, sensor 4 and function
It can circuit electrical connection.
Functional circuit includes antenna 6, governor circuit and minicell 5, and antenna 6 is electrically connected with governor circuit, governor circuit
It is electrically connected with minicell 5, sensor 4 is electrically connected with governor circuit.
In the present embodiment, sensor 4 and functional circuit are the prior art or existing product.Wherein, sensor 4 and master
Control circuit is detachable connection, can according to actual needs, and arbitrarily more emat sensor 4, meets the needs of different application scene.
In the present embodiment, governor circuit and minicell 5 become one structure.
Wireless sensor provided in this embodiment, two protective covers 2 are separately fixed at the both ends of casing 1, in fixation procedure,
The medial surface of the surface seal structure 9 that concaves of protective cover 2 is in contact and squeezes with the lateral surface of the convex inclined plane sealing structure 8 of casing 1,
Sealing structure is formed, two protective covers 2 and casing 1 form the shell of a completion, protect internal sensor 4 and functional circuit
Deng, and can effective dust waterproof, achieve the effect that effectively to seal, with it is existing using sealing ring sealing sealing structure compared with,
Assembly difficulty is reduced, and saves the cost of sealing ring.In addition, protective cover 2 and casing 1 are connected using screw thread in the present embodiment
It connects, it is convenient for assembly.
During protective cover 2 is screwed together in casing 1, the lateral surface of convex inclined plane sealing structure 8 and the surface seal structure 9 that concaves
Medial surface directly contact the seal form for forming plane-plane contact.If keeping the lateral surface of convex inclined plane sealing structure 8 and the face of concaving close
The medial surface of seal structure 9 forms a relatively narrow contact surface, and relatively narrow contact surface is leptoprosopy seal form, then can reduce pair
The requirement of machining accuracy, and then effectively improve sealing effect.Therefore, the lateral surface of convex inclined plane sealing structure 8 and the face sealing that concaves
The slope of the medial surface of structure 9 is slightly different, to make the lateral surface of convex inclined plane sealing structure 8 and the surface seal structure 9 that concaves
Leptoprosopy sealing is formed when medial surface mutual extrusion.Such as: it is close that the lateral surface maximum gauge of convex inclined plane sealing structure 8 is greater than the face that concaves
The lateral surface minimum diameter of the maximum gauge of the medial surface of seal structure 9, convex inclined plane sealing structure 8 is less than the surface seal structure 9 that concaves
Medial surface minimum diameter.Alternatively, the lateral surface maximum gauge of convex inclined plane sealing structure 8 is less than the surface seal structure 9 that concaves
The maximum gauge of medial surface, the lateral surface minimum diameter of convex inclined plane sealing structure 8 are greater than the medial surface for the surface seal structure 9 that concaves
Minimum diameter.By above-mentioned two ways, the lateral surface of convex inclined plane sealing structure 8 can be made and the surface seal structure 9 that concaves
The slope of medial surface is different, and after screwing togather, slight deformation occurs for the local mutual extrusion of concave-convex contact of incline plane, and it is close to form leptoprosopy
Envelope, to improve sealing effect.Wherein, due to the medial surface of the lateral surface of convex inclined plane sealing structure 8 and the surface seal structure 9 that concaves
It matches, therefore, the lateral surface minimum diameter of convex inclined plane sealing structure 8 is less than the maximum of the medial surface for the surface seal structure 9 that concaves
Diameter.
In the present embodiment, the size of two protective covers 2 can be identical, it is possible to have different length, different sizes,
Different shape, to be adapted to the functional circuit of different types of sensor 4 and different function.The position of functional circuit and sensor 4
It can be in any end.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention are fallen within the scope of the claimed invention.
