Detailed Description

For a better understanding of the technical solution of the present utility model, the embodiments provided by the present utility model are described in detail below with reference to the accompanying drawings.

Example 1

As shown in fig. 1, it can be understood that the quick connector provided in this embodiment includes: the pipe head seat 1 is provided with a plurality of raised support seats on the inner side of the pipe head seat 1, and the support seats comprise a first support seat 2 and a second support seat 3; a plurality of first bracket seats 2 are provided with grooves and safety valves 4 matched with the grooves, and one ends of the safety valves 4 are connected with torsion springs 5; a plurality of connecting pieces 6 are arranged on the second support bases 3, one ends of the connecting pieces 6 are fixed on the second support bases 3, and the other ends extend out of the second support bases 3. The first bracket seat 2 is provided with a shaft 8, the torsion spring 5 is sleeved on the shaft 8, and one end of the safety valve 4 is connected with the shaft 8.

The pipe head seat 1 is quick-operation joint's main part, and pipe head seat 1 in this embodiment is the ring shape, two first support seat 2 symmetry sets up, two second support seat 3 sets up on the vertical direction of two first support seat 2 lines, and is the symmetry setting, first support seat 2 and second support seat 3 are the protruding piece of rectangle, set up on the inner wall of pipe head seat 1, and the crookedness is unanimous with pipe head seat 1, relief valve 4 on the first support seat 2 is used for automatic opening when connecting the unblock, prevents the potential safety hazard, one end cover of relief valve 4 is established on torsion spring 5 and be connected with axle 8, promptly the other end of relief valve 4 uses axle 8 as the fulcrum can rotate. The connecting piece 6 on the second bracket seat 3 is used for connecting two joints. In other embodiments, the tube head seat 1 may be provided in a cylindrical shape, etc., and the first and second bracket seats 2 and 3 may be provided in a diamond shape, a circular shape, etc.

The top of the other end of the connecting sheet 6 is provided with a clamping hook 7, and the clamping hook 7 is perpendicular to the connecting sheet 6. The top of the first support seat 2 is provided with a lock hole 9, the top of the second support seat 3 is provided with a lock catch 10, and the lock catch 10 corresponds to the lock hole 9 in size. A spring is arranged below the lock catch 10, one end of the spring is fixedly connected with the lock catch 10, and the other end of the spring is fixedly arranged in the second bracket seat 3. The outside of tube head seat 1 is equipped with unlocking key 11, unlocking key 11 sets up the outside of second frame seat 3 and is connected with hasp 10.

In this embodiment, the specific connection manner of the two quick connectors is as follows: the safety valve comprises a first quick connector and a second quick connector, wherein the directions of the first quick connector and the second quick connector are corresponding to the directions in which the protruding connecting pieces 6 are arranged, one connecting piece 6 of the first quick connector and one connecting piece 6 of the second quick connector are mutually abutted against and pushed into each other, as shown in fig. 2, at the moment, the safety valve 4 of the first quick connector (the second quick connector) can be propped against the connecting piece 6 of the second quick connector (the first quick connector) and folded into a corresponding groove on the first bracket seat 2 by taking the shaft 8 as a fulcrum; the connecting piece 6 of the first quick connector (the second quick connector) is pushed to the bottom of the first bracket seat 2 of the second quick connector (the first quick connector) to start to twist clockwise or anticlockwise (clockwise or anticlockwise according to the specific design condition of the product), at this time, the hook 7 of the first quick connector (the second quick connector) rotates along the bottom of the first bracket seat 2 of the second quick connector (the first quick connector) until the locking is started after the locking is stopped, and in the embodiment, the length of the safety valve 4 is slightly longer than that of the first bracket seat 2, and the safety valve 4 is stopped when rotating to the position.
