[0027] The present invention will be further described in detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0028] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0029] This embodiment provides a rotary quick locker, comprising a connecting block 6;

[0030] like Figure 1 As shown, two insertion holes are formed through the side wall of the connection block 6, and the insertion holes are used to insert the steel pipe 11, and the diameter of the insertion holes can be φ20;

[0031] The top and bottom ends of the connection block 6 are both provided with mounting holes, and the two mounting holes are respectively connected to the two insertion holes;

[0032] like Figure 2-4As shown, a body 5 of a cylindrical structure is installed in the installation hole, and a connecting shaft 2, a rectangular spring 7, a spiral spring 8, a contact pin 9, and an annular gasket 10 are arranged in the body 5;

[0033] An annular step 15 is coaxially fixed on the inner wall of the body 5 near the insertion hole, the contact pin 9 includes a guide portion 91 and a pressing portion 92, the pressing portion 92 is slidably sleeved on the inner side of the annular step 15, the guide portion 91 is fixed on the side of the pressing portion 92 away from the insertion hole, a limit plate 14 is installed on the end of the guide portion 91 away from the pressing portion 92 through a screw 13, the limit plate 14 is fixedly sleeved on the outside of the screw 13, the annular gasket 10 is coaxially sleeved on the outside of the guide portion 91, the annular gasket 10 is located between the limit plate 14 and the pressing portion 92, and the outer diameter of the limit plate 14 is larger than the inner diameter of the annular gasket 10;

[0034] The rectangular spring 7 is coaxially sleeved on the outside of the guide portion 91, and the two ends of the rectangular spring 7 are respectively abutted against the pressing portion 92 and the annular gasket 10, and the coil spring 8 is coaxially sleeved on the outside of the rectangular spring 7, and the two ends of the coil spring 8 are respectively abutted against the annular step 15 and the annular gasket 10;

[0035] The connecting shaft 2 is coaxially sleeved inside the body 5, and the end of the connecting shaft 2 close to the insertion hole is a cylindrical structure, and the inner diameter is larger than the outer diameter of the limit plate 14, and the end of the connecting shaft 2 close to the insertion hole abuts against the annular gasket 10;

[0036] A through hole is formed on the side wall of the connecting shaft 2, and a transmission pin 3 is inserted into the through hole. Figure 6 As shown, two symmetrical spiral grooves 16 are provided on the side wall of the body 5 , and the spiral grooves 16 extend spirally up and down. The two ends of the transmission pin 3 are respectively inserted into the two spiral grooves 16 . When the connecting shaft 2 is rotated, the transmission pin 3 can move along the spiral grooves 16 .

[0037] In the loose state, the connecting shaft 2 pre-compresses the coil spring 8 through the annular gasket 10, and the rectangular spring 7 is not compressed and has no spring force. The coil spring 8 can transmit the spring force to the screw 13 through the annular gasket 10 and the limit plate 14, thereby generating a reverse force on the contact pin 9, so that the pressing portion 92 is away from the insertion hole and maintains the loose state. At this time, the pressing portion 92 does not enter the insertion hole. Figure 3 As shown, the steel pipe can freely pass through the insertion hole. When the steel pipe is needed to build the fixture plate, the steel pipe is inserted into the insertion hole, and then the connecting shaft 2 is rotated, the driving pin 3 moves along the spiral groove 16, and the connecting shaft 2 gradually approaches the insertion hole. Figure 4 As shown, the connecting shaft 2 presses down the annular gasket 10, the rectangular spring 7 and the coil spring 8 are compressed, and the rectangular spring 7 exerts downward pressure on the pressing portion 92, so that the pressing portion 92 enters the insertion hole and abuts against the side wall of the steel pipe 11, thereby achieving a locking state.

[0038] Similarly, when the connecting shaft 2 is rotated in the opposite direction, the connecting shaft 2 gradually moves away from the insertion hole. Due to the action of the coil spring 8, the annular gasket 10 gradually moves away from the insertion hole along with the connecting shaft 2. Finally, the pressing portion 92 breaks away from contact with the steel pipe 11, and the steel pipe 11 can be removed.

[0039] In summary, the rotary quick locker provided in this embodiment adopts a double spring structure to achieve quick locking. The stable spring force of the rectangular spring 7 ensures manual feedback during locking, which is more labor-saving and efficient. The friction between the contact pin 9 and the product contact surface can also be guaranteed to achieve a high sliding load and a high holding torque. No tools are required, and the locking can be completed quickly with one click manually. It is easy to assemble and operate, and the work efficiency is greatly improved. It has low cost and can be widely used in the field of automation industry.

[0040] In this embodiment, a handle 1 is installed at one end of the connecting shaft 2 away from the guide portion 91. The arrangement of the handle 1 facilitates the staff to quickly rotate the connecting shaft 2.

[0041] The handle 1 is fixedly connected to the connecting shaft 2 by screws, so that assembly or disassembly is very convenient.

[0042] The handle 1 is an umbrella-shaped structure, which can protect the driving pin 3 and the spiral groove 16 inside to avoid external interference.

[0043] like Figure 1 , 5 As shown, the handle 1 and the outer wall of the body 5 are both provided with identification lines 12. When manually locking, the identification lines can be observed by naked eyes to see whether they are consistent and by the vibration feedback on the hand to ensure complete locking.

[0044] Please refer again Figure 4 In this embodiment, a bushing 4 is sleeved on the outer side of the end of the driving pin 3, and the bushing 4 is adapted to the spiral groove 16. The provision of the bushing 4 makes the gap between the driving pin 3 and the spiral groove 16 smaller and more precise, thereby ensuring that the driving pin 3 slides smoothly in the spiral groove 16.

[0045] The mechanisms, components and parts not specifically described in the present invention are all existing structures in the prior art and can be directly purchased from the market.
