Detailed Description

The present invention will be further described with reference to the accompanying drawings.

A quick release lock assembly as shown in fig. 1 to 5 comprises a first body 10, a second body 11 and a handle 1.

The first body 10 and the second body 11 are tubular parts, the first body 10 and the second body 11 are oppositely arranged at the left and the right, and connecting flanges 19 are respectively formed at the opposite ends. The first body 10 and the second body 11 are hinged at one side and connected at the other side through the handle 1. The hinged ends of the first body 10 and the second body 11 are 180 ° apart from the handle 1. The handle 1 is in a long strip shape, one end of the handle is hinged to the first body 10 through the second rivet 3, the handle 1 can rotate to form detachable connection with the second body 11 around the hinged end of the first body 10, and the second rivet 3 is fixed through the first clamp spring 4. Specifically, a through groove 13, a through hole 20 and a connecting hole 16 are arranged at the middle position of the handle 1, the through hole 20 and the connecting hole 16 are respectively arranged at two ends of the through groove 13, the connecting hole 16 is close to the first body 10, and the through hole 20 is far away from the first body 10. The front end of the ejector rod 9 is fixedly connected into the connecting hole, the through hole 20 is connected with the cylindrical nut 8, and the rear end of the ejector rod 9 is fixedly connected with the cylindrical nut through threads. The ejector rod 9 is connected with a buckle 6 in a sliding mode, and the buckle 6 is arranged in the through groove 13. The buckle 6 can slide along the mandril 9, and the sliding direction is the length direction of the handle 1. The portion of the catch 6 protruding upward out of the through slot 13 forms an operating portion 14, and the portion of the catch 6 protruding downward out of the through slot 13 forms a hooking portion 15. The upper surface of the handle 1 is provided with a circular arc concave surface 18, and the operating part 14 extends into the circular arc concave surface 18. The second body 11 is provided with a locking groove 12 below the through groove 13, and the hooking portion 150 is slidably hooked with the locking groove 12, so that the first body 10 and the second body 11 are relatively fixed. In order to prevent the buckle 6 from being separated from the clamping groove 12, the ejector rod 9 is sleeved with a connecting spring 7, the spring 7 is a compression spring 7, and two ends of the spring 7 are respectively connected with the buckle 6 and the cylindrical nut 8 in a jacking mode.

The ejector rod 9 extends out of the connecting hole 16 to form an abutting end 17. The second body 11 is connected with a first rivet 2, the first rivet 2 is provided with an arc surface and is fixed through a second clamp spring 5; when the handle 1 is hooked with the clamping groove 12, the abutting end 17 is connected with the arc surface of the first rivet 2 in a pressing mode.

The bottom surface a of the hooking portion 15 and the front upper surface B of the engaging groove 12 are both provided with inclined surfaces, and the bottom surface a is approximately parallel to the inclined surfaces B. When the handle 1 is pressed down, the buckle 6 is pressed and moves backwards under the action of the bottom surface A and the inclined surface B to be hooked with the clamping groove 12.

The operating method of the quick-release locking assembly is as follows: when the first body 10 and the second body 11 need to be locked, the handle 1 is rotated around the hinge joint with the first body 10 until the buckle 6 and the clamping groove 12 are separated; when the first body 10 and the second body 11 need to be disassembled, the buckle 6 is moved backwards, and meanwhile, the handle 1 is lifted.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
