[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figures 1-4 This utility model provides a mechanically quick-connect mining measurement connector, including a handheld shell 1, a connecting block 2 fixedly connected to one end of the handheld shell 1, a fixing block 3 fixedly installed inside the handheld shell 1, a drill bit connecting assembly fixedly installed on one side of the fixing block 3, four threaded holes 12 equally spaced on the handheld shell 1, four mounting grooves 19 equally spaced on the inner wall of the handheld shell 1, a locking assembly threadedly connected inside the threaded holes 12, a locking assembly lockingly connected to the outside of the locking assembly, a connector assembly fixedly installed at one end of the locking assembly, and a positioning assembly fixedly installed inside the mounting grooves 19.

[0022] Furthermore, the drill bit connection assembly includes an insulating connector 4, which is fixedly installed at one end inside the handheld housing 1. A metal connector 5 is fixedly installed inside the insulating connector 4. A shaped spring 6 is fixedly installed at one end of the metal connector 5, and a copper wire 7 is fixedly installed at the other end of the metal connector 5. One end of the copper wire 7 passes through the fixing block 3, fixing the drill bit inside the insulating connector 4 so that one of its parts contacts the metal connector 5.

[0023] Furthermore, the engaging assembly includes four threaded cylinders 13, which are threadedly connected to the interior of four threaded holes 12. A lead screw 14 is threadedly connected to the interior of each threaded cylinder 13. A knob 15 is fixedly installed on the top of the lead screw 14, and a compression ball 16 is fixedly installed on the bottom of the lead screw 14. Multiple slots are opened at one end of the threaded cylinder 13, and engagement balls 17 are movably connected inside each slot. The compression ball 16 contacts and connects with the corresponding multiple engagement balls 17. The compression ball 16 can only protrude out of the outer wall of the threaded cylinder 13 through the corresponding slot and will not fall out of the threaded cylinder 13.

[0024] Furthermore, the locking assembly includes an end cap 8, which is slidably installed inside the handheld housing 1. Four locking plates 18 are installed on the end cap 8, and the four locking plates 18 are slidably connected to four threaded cylinders 13 respectively. The locking plates 18 are engaged with corresponding locking beads 17. Four locking openings 20 are equidistantly provided on the outer wall of the end cap 8.

[0025] Furthermore, the connector assembly includes a sealing connector 9, which is fixedly installed at one end of the end cap 8. A sealing gasket 10 is installed inside the sealing connector 9, and a probe 11 is fixedly installed between the sealing connector 9 and the sealing gasket 10. One end of the probe 11 passes through the middle of the end cap 8 and is in contact with the copper wire 7. After the drill bit and the end cap 8 are connected to the body, the drill bit makes contact with the metal connector 5 to conduct electricity to the copper wire 7. The probe 11 makes contact with the other end of the copper wire 7 to conduct electricity. Thus, when power is applied for measurement, the electrical connection becomes a circuit. The drill bit performs the measurement, and then the measurement information is transmitted to the probe 11 along the copper wire 7. The probe 11 feeds back the measurement information to the measuring instrument.

[0026] Furthermore, the positioning assembly includes four engaging springs 21, which are respectively fixedly installed inside the four mounting slots 19. One end of each of the four engaging springs 21 is fixedly installed with an engaging block 22. The four engaging blocks 22 are respectively engaged with the four engaging ports 20. The connection between the engaging blocks 22 and the engaging ports 20 does not directly serve a fixing function; a slight force is applied to make contact. The connection between the engaging blocks 22 and the engaging ports 20 only serves to align the locking plate 18 with the threaded cylinder 13.

[0027] In this embodiment, the handheld shell 1 and the sealing connector 9 are designed to be separate. When it is necessary to disconnect them, the knob 15 is turned to drive the lead screw 14 to rise inside the threaded cylinder 13. When the lead screw 14 rises, it drives the bottom compression ball 16 to rise synchronously, releasing the compression ball 16 from the locking bead 17. After the locking bead 17 is no longer compressed, it will release its engagement with the corresponding locking plate 18. Then, by rotating the threaded cylinder 13, it slides away from the locking plate 18 while rising inside the threaded hole 12, no longer limiting the locking plate 18. At this time, the separation between the handheld shell 1 and the end cap 8 is completed. The end cap 8 drives the fixedly connected sealing connector 9 to disconnect from the handheld shell 1, and also drives the probe 11 to disconnect from the copper wire 7. When the end cap 8 is fixedly connected to the handheld shell 1 again, one end of the end cap 8 is slidably installed on one end of the handheld shell 1. When the end cap 8 contacts the fixing block 3 When the probe 11 is blocked, it will also contact and connect with the copper wire 7. At this time, the four locking blocks 22 will be squeezed. The locking blocks 22 will be inside the corresponding mounting groove 19 and the locking spring 21 will be stressed. Then, the end cover 8 will be rotated to align the locking opening 20 with the locking block 22. When the locking opening 20 is aligned with the locking block 22, the locking spring 21 will release the squeezing force, so that the locking block 22 will lock inside the locking opening 20. At this time, the four locking plates 18 will be aligned with the threaded cylinder 13. Rotate the threaded cylinder 13 to drive it down inside the threaded hole 12 and slide it into the locking plate 18 to limit the locking plate 18. Then rotate the knob 15 to drive the screw 14 to drive down inside the threaded cylinder 13. When the screw 14 descends, it drives the bottom squeezing ball 16 to squeeze the locking ball 17, so that it protrudes along the corresponding groove to the outside of the threaded cylinder 13 and locks with the locking plate 18, thus completing the locking between the end cover 8 and the handheld shell 1.
