Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Please refer to fig. 1-4, a sensor protection sleeve, which comprises a protection sleeve 1, a T-shaped groove 2 is formed in the middle of the protection sleeve 1, a sensor 3 is fixedly mounted in the middle of the protection sleeve 1 through the T-shaped groove 2, a fastening thread 4 is formed on the outer surface of a flange in the middle of the sensor 3, a sealing thread 5 is formed on the outer surface of an induction core at the bottom of the sensor 3, a pressing thread 6 is formed on the outer surface of the protection sleeve 1, a chamfer 7 is formed on the outer surface at the bottom of the protection sleeve 1, a nut 8 is installed on the outer surface of the protection sleeve 1 through the pressing thread 6, and an air outlet 9 is formed in the upper.

Wherein, partial pressure groove 10 has been seted up to the internal surface of T type groove 2, and partial pressure groove 10 has four, and evenly distributed is at the internal surface of T type groove 2, through the partial pressure groove 10 of seting up, separates sensor 3 and the negative pressure between the lag 1 for when lag 1 leaks gas, lag 1 can not separate with sensor 3 immediately, has guaranteed lag 1 to sensor 3's guard time, has promoted sensor 3's life.

Wherein, the bottom diameter of chamfer 7 and the internal diameter cooperation of nut 8, the internal diameter of nut 8 is less than lag 1's external diameter, nut 8 upwards screw in from bottom to top, through the chamfer 7 of seting up for screw in that nut 8 can be more relaxed to lag 1's surface, nut 8 that the diameter is little can extrude lag 1, make the air between lag 1 and the sensor 3 pass through venthole 9 and discharge, guarantee that lag 1 can wrap up tight sensor 3, and the protective effect is better.

Wherein, elastic hole 11 is seted up to the inside of lag 1, and elastic hole 11 arrays are seted up, through the elastic hole 11 of seting up for lag 1 is the fretwork design, can promote the elasticity of lag 1 itself, thereby improves the anti striking ability of lag 1, promotes lag 1 to the guard effect of sensor 3.

Wherein, venthole 9 is the form of buckling, and the gas outlet direction is perpendicular with nut 8's diametric (al) direction, through the venthole 9 of buckling for nut 8 is rotatory behind the upper portion of lag 1, and extrusion lag 1 makes venthole 9 closed, thereby prevents that the air from passing through venthole 9 and re-entering lag 1 and sensor 3's gap, guarantees the negative pressure effect, has guaranteed lag 1 and has acted on sensor 3's parcel, prevents that sensor 3 from rocking and damaging.

The working principle of the invention is as follows:

the sensor 3 is sleeved into a T-shaped groove 2 in the middle of a protective sleeve 1, the sensor 3 is rotated, a fastening thread 4 is fixedly matched with the upper part of the T-shaped groove 2, a sealing thread 5 on the lower part of the sensor 3 is sealed with a bottom thread of the protective sleeve 1, a sealed space is formed between the protective sleeve 1 and the sensor 3 after matching, a nut 8 is screwed from bottom to top through a compression thread 6, air between the protective sleeve 1 and the sensor 3 is discharged through an air outlet hole 9 under the displacement of the nut 8 to form a negative pressure state, the nut 8 stays at the upper part of the protective sleeve 1 and can extrude the air outlet hole 9 to prevent air from flowing in, the negative pressure disappears, a pressure dividing groove 10 which is arranged in a separating way can divide the negative pressure into sections, when air leakage fails, all the air cannot fail, and meanwhile, an elastic hole 11 which is arranged can improve the buffering effect of the protective sleeve 1 when the air leakage, the impact force applied to the sensor 3 is reduced, and the service life of the sensor 3 is prolonged.
