DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figures 1 to 4 In an embodiment of the utility model, a drill bit quick-release connector 100 includes: a drill rig connection sleeve 10, a drill bit connection sleeve 20 and a locking mechanism 30. The drill rig connection sleeve 10 is used to connect the output shaft of the drill rig. The drill bit connection sleeve 20 is used to connect the drill bit. The locking mechanism 30 is used to lock the drill rig connection sleeve 10 and the drill bit connection sleeve 20. The drill bit connection sleeve 20 can be detachably inserted into the drill rig connection sleeve 10. The drill rig connection sleeve 10 is formed with a hollow hole 11. The drill bit connection sleeve 20 is formed with a center hole 21. The center hole 21 is used for water conduction. The center hole 21 is connected to the hollow hole 11. The drill bit connection sleeve 20 includes: a sealing section 201, an external spline transmission section 202, a locking section 203 and an installation section 204. The installation section 204 is used to install the drill bit. The sealing section 201, the external spline transmission section 202, the locking section 203 and the installation section 204 are arranged in sequence. An O-ring 22 is provided between the sealing section 201 and the drilling rig connection sleeve 10. The external spline transmission section 202 is spline-connected to the drilling rig connection sleeve 10 to transmit torque. The locking section 203 is provided with an annular groove 2031.
[0025] The locking mechanism 30 includes: a sliding sleeve 31, a compression spring 32, a slider 33 and a stopper 34. The drilling rig connection sleeve 10 is formed with a sliding groove 12. The sliding groove 12 guides the slider 33 to slide. The stopper 34 is installed on the drilling rig connection sleeve 10. The compression spring 32 is arranged between the stopper 34 and the sliding sleeve 31. The sliding sleeve 31 is slidably installed on the drilling rig connection sleeve 10. The sliding sleeve 31 has a locking position and an unlocking position relative to the drilling rig connection sleeve 10. The compression spring 32 applies a force to the sliding sleeve 31 to move from the unlocking position to the locking position.
[0026] The sliding sleeve 31 is provided with an escape groove 311 for the slider 33 to enter. When the sliding sleeve 31 is in the unlocking position, the escape groove 311 is aligned with the slide groove 12 so that the slider 33 can slide out of the annular groove 2031. When the sliding sleeve 31 is in the locking position, the escape groove 311 is offset from the slide groove 12, and the inner wall surface of the sliding sleeve 31 blocks the slide groove 12 to prevent the slider 33 from sliding out of the annular groove 2031.
[0027] Specifically, the O-ring 22 can achieve sealing and prevent water leakage. The external spline transmission section 202 is connected to the drilling rig connection sleeve 10 through a spline to transmit torque, and the transmission stability is high.
[0028] As a specific implementation, the groove wall of the annular groove 2031 is an arc surface. Both ends of the slider 33 are set to be hemispherical.
[0029] As a specific implementation, the limiting member 34 is a retaining spring.
[0030] As a specific implementation, the installation section 204 is provided with a first external thread structure and a first internal thread structure. The first external thread structure is used to connect the drill bit.
[0031] As a specific implementation, a second internal thread structure is provided on the inner wall surface of the hollow hole 11. The second internal thread structure is used to connect the output shaft of the drilling rig.
[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
