The connecting device body 1 is further formed with a stepped hole penetrating from the outer wall to the inner wall of the mounting hole 7, and the locking pin 14 is mounted in the stepped hole. When the locking pin 14 is acted by an inward force, the tail part of the locking pin can extend into the mounting hole 7, and a spring 15 which exerts an outward force on the locking pin 14 is arranged between the head part 14.1 of the locking pin 14 and the bottom surface of the outer side hole 16 of the stepped hole.
The upper part of the pressure head 11 is in clearance fit in the mounting hole 7, and the outer wall of the upper part is provided with a ring-shaped groove 13 corresponding to the position of a locking pin 14 along the circumferential direction.
The locking sleeve 8 is in sliding fit with the outer portion of the connecting device body 1, a stepped hole 17 is formed in the lower end of the locking sleeve 8, the diameter of the stepped hole 17 is larger than the diameter of an inner hole of the locking sleeve 8, and as shown in fig. 4, the diameter difference is 2 x h. The locking sleeve 8 is provided with an L-shaped track groove 6, the track groove 6 consists of a vertical section and a horizontal section, the vertical section extends downwards along a bus of the locking sleeve 8, and the horizontal section is suspended in the circumferential direction of the locking sleeve 8. The track groove 6 is engaged with a track pin 5, and the track pin 5 passes through the track groove 6 and is fixed to the connecting device body 1. The tail end of the horizontal section of the track groove 6 is provided with an arc-shaped self-locking groove 6.1 which is concave upwards.
The outer wall of the middle part of the pressure head 11 is provided with a lower flange 12, the lower flange 12 is tightly attached to the lower end face of the connecting device main body 1, the lower flange 12 and the lower end face of the connecting device main body 1 are provided with corresponding pin holes 10, and the positioning pin 9 penetrates through the pin hole 10 of the lower flange 12 and is in transition fit in the pin hole 10 of the lower end face, so that the pressure head 11 is prevented from rotating relative to the connecting device main body 1.
The working principle of the utility model is as follows:
(1) installing a pressure head:
the upper section of the pressure head 11 is inserted into the mounting hole 7 at the lower end of the connecting device main body 1, and the positioning pin 9 is inserted to prevent the pressure head 11 from rotating circumferentially; as shown in fig. 2 and 4, the locking sleeve 8 is slid downwards so that the track pin 5 reaches the upper end of the vertical section of the track groove 6, the inner wall of the locking sleeve 8 presses against the head 14.1 of the locking pin 14, the locking pin 14 is pushed into the annular groove 13 of the pressure head 11, and the pressure head 11 is locked in the axial direction; then, the locking sleeve 8 is rotated to enable the track pin 5 to reach the horizontal section of the track groove 6, and the pressure head 11 maintains a locking state, as shown in fig. 6, when the track pin 5 reaches the tail end of the horizontal section, the locking sleeve 8 slides downwards for a short distance to enable the track pin 5 to enter the self-locking groove 6.1, the track pin 5 is locked, and the track pin 5 is prevented from sliding back to the vertical section to cause the pressure head 11 to be loosened;
