[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Example 1: This Example 1 provides a quick-release device for a disc-lock type full-span support frame. It is a direct improvement on the existing disc-lock design, with a unique structure. Please refer to [link / reference]. Figure 1-4 As shown, it includes a connecting plate 3 set on the upright 1 and a U-shaped connector 4 set on the crossbar 2. The top of the connecting plate 3 is evenly provided with multiple insertion holes 5 along the circumference. The top of the connector 4 is fixedly installed with a fixing cylinder 6. Both horizontal plates of the connector 4 are provided with through holes that are concentric with the fixing cylinder 6. The inside of the fixing cylinder 6 is fitted with a vertically sliding insert rod 9, and the diameter of the insert rod 9 is the same as that of the insertion hole 5.

[0017] The upper end of the insertion rod 9 is fixedly fitted with a ring platform II 8, and the lower end extends into the connector 4 and is concentrically fixedly connected to a connecting rod 21. A frustum I 10 and a frustum II 11 are fitted on the connecting rod 21. A spring II 16 is fitted on the insertion rod 9 between the connector 4 and the ring platform II 8. The frustum I 10 is fixedly connected to the connecting rod 21, and the frustum II 11 is slidably connected to the connecting rod 21. There are multiple ways to fix the frustum I 10 to the connecting rod 21, such as: the frustum I 10 is threaded to the insertion rod 9. In addition, the installation is facilitated by the cooperation of the nut 13 and the round head bolt 14. In the initial state, the bottom surface of the frustum I 10 is flush with the inner top surface of the connector 4, which makes it easy to insert the connecting disc 3 into the connector 4.

[0018] The adjacent ends of frustum I 10 and frustum II 11 are both large ends and have the same diameter as the insertion rod 9. Frustum II 11 is provided with spring I 15 to suspend it above frustum I 10, and there is a certain gap between frustum I 10 and frustum II 11. A mounting groove 17 is radially opened on the side wall of the through hole. A locking tongue 18 is slidably fitted in the mounting groove 17. A spring III 19 is fixedly installed at the end of the locking tongue 18 away from the through hole. The other end of the spring III 19 is fixedly connected to the connector 4.

[0019] The inner side of the top of the fixed cylinder 6 is fixedly fitted with a ring truncated cone I 7, a cone truncated cone I 10, and a cone truncated cone II 11. Multiple countersunk holes 12 are opened on the conical surfaces of the cones I 10 and II 11. The countersunk holes 12 on the two cones correspond one to one. A nut 13 is fixedly fitted in the countersunk hole 12 on the cone II 11. A round head bolt 14 is movably fitted in the countersunk hole 12 on the cone I 10. The round head bolt 14 is threadedly connected to the nut 13. There are multiple springs I 15. The multiple springs I 15 are respectively fitted on the screw of the corresponding round head bolt 14, and the two ends of the springs I 15 extend into the countersunk holes 12 on the adjacent sides. The cone II 11 is suspended on the cone I 10 under the pushing force of the springs I 15.

[0020] The mounting groove 17 has a mounting groove connected to the end away from the through hole. A cover plate 20 is bolted to the mounting groove, and a spring Ⅲ 19 is fixedly connected to the cover plate 20. There are multiple ways to install the latch 18. For example, a limit groove is opened on the side wall of the mounting groove 17, and a slider is slidably installed in the limit groove. The slider is fixedly connected to the latch 18. Through the design of the limit groove and the slider, the latch 18 is prevented from popping out of the mounting groove 17.

[0021] Working principle: When using this device, first align the through hole on the connector 4 with the corresponding insertion hole 5, and then use a steel bar or push rod to drive the insertion rod 9 downward. During the downward movement of the insertion rod 9, the truncated cone I 10 first contacts the inclined surface of the locking tongue 18 and squeezes it into the mounting groove 17. When the truncated cone I 10 moves below the locking tongue 18, the locking tongue 18 will pop out under the action of the spring III 19 and insert into the gap between the truncated cone I 10 and the truncated cone II 11, thereby locking the insertion rod 9 into the insertion hole 5, thus connecting the connector 3 and the connector 4 together.

[0022] When the support frame needs to be removed, simply use the reinforcing bar or push rod to drive the insert rod 9 downwards again, so that the truncated cone II 11 also moves below the locking tongue 18. Then release the insert rod 9, and the insert rod 9 moves upwards under the action of the spring II 16. During the upward movement of the insert rod 9, the conical surface of the truncated cone II 11 first contacts the locking tongue 18. Since the elastic force of the spring I 15 is small, the spring I 15 is compressed at this time, and the distance between the truncated cone I 10 and the truncated cone II 11 will continue to decrease. When the two touch, the truncated cone I 10 will hit the truncated cone II 11. Moreover, since the diameters of the large ends of the two are the same, the locking tongue 18 can be squeezed back into the mounting groove 17. Then, they move simultaneously above the locking tongue 18. At this time, the connecting plate 3 and the connecting head 4 can be separated.

[0023] Example 2: The difference between Example 2 and Example 1 is as follows: Figure 1 As shown, the edges of both the upper and lower ends of the connecting plate 3 are chamfered to facilitate the insertion of the connecting plate 3 into the connector 4.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
