As shown in fig. 3 and 4, the utility model discloses a ball 25 in quick locking device's the second tapered end 2 can block into the draw-in groove 121 of reference column 12 in the first tapered end 1, thereby realize the locking of first tapered end 1 and second tapered end 2, through pressing the press head 21, can compress spring 24, make relative movement take place between inner tube 22 and the urceolus 23, because the bell mouth 2311 has been seted up to the second end of urceolus 23, the ball 25 that is locked originally can be to keeping away from the central one side removal of inner tube 22, the locking state that makes ball 25 and draw-in groove 121 is relieved, thereby realize the unblock of first tapered end 1 and second tapered end 2. As shown in fig. 1, when the first component 100 and the second component 200 need to be locked, they are stacked together and drilled, the positioning column 12 passes through the first component 100 and the second component 200, and then the first locking head 1 is locked with the second locking head 2, i.e. the first component 100 and the second component 200 can be locked.

The utility model discloses a quick locking device simple structure, convenient to use can show the speed that improves the installation and dismantle, shortens installation time to save the cost of labor.

When the pressing head 21 is pressed by a palm, a finger can be placed on the flange 232, so that the relative movement between the inner cylinder 22 and the outer cylinder 23 is convenient to realize, the human engineering is met, and the use by an operator is convenient.

As shown in fig. 2, the diameter of the positioning hole 221 on the side away from the outer cylinder 23 is smaller than the diameter of the ball 25, and the diameter of the positioning hole 221 on the side close to the outer cylinder 23 is larger than the diameter of the ball 25. Therefore, the balls 25 do not fall into the inner cylinder 22, but the balls 25 can move to a side away from the center of the inner cylinder 22 and abut against the hole wall of the tapered hole 2311, so that the positioning column 12 can be smoothly inserted into the inner cylinder 22. When the tapered hole 2311 is formed, attention needs to be paid to the size of the ball 25 so that the outer cylinder 23 can prevent the ball 25 from falling out from between the outer cylinder 23 and the inner cylinder 22.

As shown in fig. 2, a stepped hole is provided in the outer cylinder 23, and an end surface of the end of the inner cylinder 22 connected to the pressing head 21 can abut against a stepped surface 2312 of the stepped hole. When the pressing head 21 is not pressed, the pressing head 21 and the outer cylinder 23 are separated from each other by the elastic force of the spring 24, the inner cylinder 22 is fixedly connected with the pressing head 21, and the step surface 2312 is arranged, so that the end surface of the inner cylinder 22 is abutted to the step surface 2312, a limiting effect can be achieved, the spring 25 is prevented from being continuously deformed, and therefore, when the first lock head 1 and the second lock head 2 are locked, the inner cylinder 22 and the outer cylinder 23 are kept relatively static and cannot move.

As shown in fig. 2, a mounting groove 211 is formed in the pressing head 21, the mounting groove 211 has a ring shape, and one end of the spring 24 is disposed in the mounting groove 211. The mounting groove 211 plays a limiting role in the spring 24, so that the spring 24 is kept in a stable form, the spring is not easy to twist in the radial direction, and the reliability of the spring 24 is improved.

Furthermore, one end of the spring 24, which is far away from the mounting groove 211, is sleeved on the surface of the outer cylinder 23, so that the outer cylinder 23 also has a limiting effect on the spring 24, and the reliability of the spring 24 is further improved.

As shown in fig. 2, the pressing head 21 is provided with a stepped structure 212, and as shown in fig. 3, the end surface of the first end of the outer cylinder 23 can abut against the stepped structure 212. In the locking process of first tapered end 1 and second tapered end 2, spring 24 is compressed, and the terminal surface of the first end of urceolus 23 plays limiting displacement through the butt with stair structure 212, avoids letting spring 24 itself play limiting displacement. The spring 24 has a relatively stable limit only when it is compressed to the limit, which adversely affects the service life of the spring 24. The end surface of the first end of the outer cylinder 23 is abutted against the step structure 212, so that the limiting effect is more reliable and stable, and the spring 24 is prevented from being excessively compressed.

In the embodiment, the end surface of the pressing head 21 far from the end of the inner cylinder 22 is a spherical crown surface, which is more in line with human engineering, so that the operator can press the pressing head 21 with the palm more comfortably and the use experience is good.

As shown in fig. 1, 3 and 4, one end of the positioning column 12 away from the bottom plate 11 is in a truncated cone shape. The small end of the positioning column 12 can be firstly inserted into the inner cylinder 22, and after the ball 24 contacts with the positioning column 12, the first lock head 1 and the second lock head 2 can be automatically centered, so that the operation is convenient for personnel.

In this embodiment, the inner cylinder 22 is clearance-fitted with the outer cylinder 23. In the process of locking or unlocking the first lock head 1 and the second lock head 2, the inner cylinder 22 and the outer cylinder 23 move relatively, and the inner cylinder 22 and the outer cylinder 23 are in clearance fit, so that the friction force generated when the inner cylinder 22 and the outer cylinder 23 move relatively is small, the use by personnel is more convenient, the abrasion between the inner cylinder 22 and the outer cylinder 23 can be reduced, and the long service life is realized.
