DETAILED DESCRIPTION

[0022] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0023] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features. Specific embodiments

[0024] like Figure 1-8As shown, a quick-locking quick-release mechanism comprises an upper support 1, a lower support 3, and a rivet 15. The upper support 1 is placed on the lower support 3, and the rivet 15 is fixed to the bottom of the upper support 1. A ball 7 and a cam structure 16 are installed in the lower support 3. A groove 18 is provided in the middle of the cam structure 16, and the inner wall of the groove 18 constitutes a cam path 10. A downwardly opening slide 17 is provided in the middle of the lower support 3, and the cam structure 16 is embedded in the slide 17 of the lower support 3. The cam structure 16 can rotate along the slide 17, and a plurality of bosses 8 are provided in the middle of the slide 17. All bosses 8 form a circle and extend into the groove 18 on the cam structure 16. A plurality of ball grooves 11 are left between adjacent bosses 8. All balls 7 are placed on the slide 17 inside the lower support 3 and are correspondingly restricted in the ball grooves 11. There is space for the corresponding ball 7 to move radially. A rivet hole a19 is provided in the center of the slide groove 17 of the lower support 3, and a rivet hole b22 is provided in the center of the cam structure 16. A groove 13 is provided in the middle section of the rivet 15, and a cone head 12 with a length of 1-15mm is provided at the bottom. The rivet 15 extends from the top of the lower support 3 through the rivet hole a19 into the rivet hole b22 in the center of the cam structure 16. When the cam structure 16 is rotated forward, the ball 7 is restricted by the cam path 10, and is squeezed against the groove 13 of the rivet 15 to lock the rivet 15. When the cam structure 16 is rotated backward, the ball 7 is freed from the restriction of the cam path 10, and the rivet 15 is released. The cone head 12 at the bottom of the rivet 15 is 1-15mm long and is used to prevent the upper support 1, the lower support 3 and the rivet 15 from being stuck due to installation mismatch caused by manufacturing tolerance.

[0025] The rivet 15 is connected by a connecting piece 20 in a manner of extending from top to bottom through a connecting hole 21. The connecting piece 20 is fixed to the bottom of the upper support 1. The connecting hole 21 is an upward through hole. When the components of the quick-release mechanism do not fit and get stuck due to manufacturing tolerances, they can be removed without violent damage with an impact drill, thereby protecting the components of the quick-release mechanism and saving time and labor costs.

[0026] The lower support 3 is provided with a guide groove 6 , and a handle 4 is fixedly connected to one side of the cam structure 16 , and the handle 4 extends outward from the guide groove 6 .

[0027] A retaining spring 2 is provided at the bottom of the cam structure 16 , and the cam structure 16 is fixed in the lower support 3 by the retaining spring 2 .

[0028] There are three balls 7 in total, and the groove 18 on the cam structure 16 is circular, with three arc grooves 9 evenly distributed on the edge of the groove 18. When the three balls 7 correspond to the arc grooves 9 on the cam structure 16 respectively, the pull nail 15 is loosened, and when the three balls 7 correspond to the three side arc surfaces on the cam structure 16 respectively, the pull nail 15 is locked.

[0029] A positioning bolt 5 is fixed at the bottom of the upper support 1, and a positioning bolt hole 14 used in conjunction with the positioning bolt 5 is provided on the lower support 3. The lower end of the positioning bolt 5 extends into the positioning bolt hole 14 of the lower support 3 to position the upper support 1 and the lower support 3.

[0030] The lower support 3 is a hollow structure, which reduces weight and saves materials. Specific embodiments

[0031] A detection platform is provided with two sets of quick-release mechanisms having a structure similar to that of the specific embodiment 1, except that the upper support 3 is not provided with a positioning bolt 5, and two parallel quick-release mechanisms are provided on the detection platform. The upper supports 1 of the two parallel quick-release mechanisms are integrally formed to prevent rotation, and the combination is suitable for the detection of long pieces.

[0032] Working principle:

[0033] When the rivet 15 extends into the rivet hole 19 of the lower support 3, the ball 7 in the ball groove 11 is squeezed outward. At this time, the ball 7 is located in the arc groove 9 of the cam structure 16. When the handle 4 is rotated forward, the ball 7 is restricted by the cam path 10 and squeezed by the groove 13 in the middle section of the rivet 15, locking the rivet 15. When the handle 4 is rotated backward, the ball 7 is freed from the restriction of the cam path 10, releasing the rivet 15.

[0034] The beneficial effect is that the upper support and the lower support can be quickly connected or disassembled through the cooperation of the rivet and the ball, the cone head 12 at the bottom of the rivet 15 is 1-15mm long, and when the components of the quick-release mechanism are not installed properly due to manufacturing tolerances, the rivet 15 is skewed and is not easy to get stuck. In addition, the rivet 15 is fixed to the bottom of the upper support 1 by a connecting member 20 from top to bottom, and the connecting hole 21 is an upward through hole, which is easy to install. When the rivet 15 is stuck, it can be removed without violently destroying the components with an impact drill, thereby reducing losses. The lower support 3 is a hollow structure, which reduces weight and saves costs.

[0035] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
