[0006] The present invention is further configured such that a connecting part is fixedly installed at the top of the airspeed tube shell, the connecting part is fixedly connected to the dynamic pressure tube, and an anti-slip sleeve is embedded in the outer wall of the connecting part.

[0007] The present invention is further configured such that multiple mounting seats are fixed in a ring array at the bottom of the outer wall of the airspeed tube seat, and fastening holes are provided on the mounting seats.

[0008] The present invention is further configured such that a fastening bolt is provided above the mounting base, and the bottom end of the fastening bolt is slidably inserted into the fastening hole.

[0009] The present invention is further configured such that a mounting hole is provided at the center of the airspeed tube housing, and the dynamic pressure tube is embedded and fixed in the mounting hole.

[0010] The present invention is further configured such that a wire receiving hole is provided at the bottom end of the airspeed tube shell, which is embedded in a first threaded hole, and a through hole corresponding to the wire receiving hole is provided on the inner wall of the first threaded hole.

[0011] The present invention is further configured such that a protruding tube is fixedly installed in the groove at the bottom end of the airspeed tube seat, and the bottom end of the dynamic pressure tube is embedded in the protruding tube.

[0012] In summary, the present invention has the following advantages: The present invention has a connecting part fixed to the airspeed tube housing, and a dynamic pressure tube fixed to the connecting part is embedded in the mounting hole at the center of the airspeed tube housing. The anti-slip sleeve drives the airspeed tube housing and the dynamic pressure tube to rotate synchronously through the connecting part, thereby causing the first threaded part and the second threaded part to be threadedly inserted into the first threaded hole and the second threaded hole respectively. When the dynamic pressure tube extends into the airspeed tube seat, it contacts and locks with the first threaded hole. The thread of the dynamic pressure tube on the airspeed tube housing engages with the thread of the second threaded hole for locking, facilitating the installation and disassembly of the airspeed tube and improving the convenience of airspeed tube installation and disassembly.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] A detachable pitot tube, such as Figure 1-4As shown, it includes an airspeed tube holder 3 and an airspeed tube housing 1 embedded and fixed in the airspeed tube holder 3. A dynamic pressure tube 8 is embedded and fixed in the airspeed tube housing 1, and the outer wall of the airspeed tube housing 1 is provided with a first threaded part 6. The bottom end of the dynamic pressure tube 8 is provided with a second threaded part 9. The top end of the airspeed tube holder 3 is provided with a first threaded hole 16, and the center of the bottom wall of the first threaded part 6 is provided with a second threaded hole 13. The first threaded part 6 is threaded into the first threaded hole 16, and the second threaded part 9 is threaded into the second threaded hole 13.

[0020] A connecting part 2 is fixedly installed at the top of the airspeed tube housing 1. The connecting part 2 is fixedly connected to the dynamic pressure tube 8, and an anti-slip sleeve 5 is embedded in the outer wall of the connecting part 2. Multiple mounting seats 4 are fixed in a ring array at the bottom of the outer wall of the airspeed tube seat 3. Fastening holes 12 are opened on the mounting seats 4, and fastening bolts 14 are provided above the mounting seats 4. The bottom end of the fastening bolts 14 is slidably inserted into the fastening holes 12.
