Embodiment Construction
[0030] Embodiment 1 of a push-pull locking structure, in Figure 1~9 Among them, including the basic cylinder 1, the outer peripheral surface of the basic cylinder 1 is provided with a fixed ring groove 12, and a C-shaped locking ring 3 is forcibly installed in the fixed ring groove 12, and the C-shaped locking ring 3 has an axial gap 9, the C-shaped ring body, the C-shaped locking ring 3 has radial elasticity, when it is assembled in the fixed ring groove 12, the C-shaped locking ring 3 is stretched and it is placed on the base cylinder due to one end of the base cylinder On the base cylinder, when the C-shaped locking ring moves into the fixing ring groove 12, the C-shaped locking ring 3 shrinks and is fixedly assembled in the fixing ring groove 12. The two ends of the basic cylinder 1 are respectively sleeved with the connecting cylinder 4 and the unlocking sliding sleeve 2. After the assembly is completed, the ends of the C-shaped locking ring 3 extend into the connecting ...

The invention relates to a push-and-pull locking structure. A C-shaped locking ring is forcedly arranged in a fixed ring slot at the outer peripheral surface of a base cylinder of the structure, one end of the base cylinder is sleeved with an unlocking sliding sleeve, a corresponding end of the C-shaped locking ring extends into a port of the unlocking sliding sleeve, the circumferential section of the end part of the C-shaped locking ring extending into the unlocking sliding sleeve is a conical surface section of a flaring end extending to the end surface point, and the inner circumferential surface of the unlocking sliding sleeve is provided with a pushing structure which extrudes the conical surface section of the C-shaped locking ring so as to make the C-shaped locking ring retracted in an inwards convex mode. The other end of the base cylinder is sleeved with a connecting cylinder, the circumferential surface of an inner hole of the connecting cylinder is provided with a locking ring slot, the corresponding end of the C-shaped locking ring is provided with an annular convex edge, an inner end surface of the annular convex edge is matched with a slot wall of the locking ring slot in a movement stop propping mode, the outer end surface of the annular convex edge is the conical surface of a contraction end extending to the end surface point, and the circumferential surface part of the inner hole of the corresponding port of the connecting cylinder is the conical surface coincided and matched with the outer end surface of the annular convex edge to extrude the C-shaped locking ring to be retracted.
Description
technical field [0001] The invention relates to a mechanical locking structure for locking two cylinders together, in particular to a mechanical locking structure that locks the two cylinders when they are pushed together, and separates when the two cylinders are pulled outward. Push-pull locking structure. Background technique [0002] In the field of machinery, it is sometimes necessary to lock two cylinders together. There is a locking structure in the prior art, which is to set a fixed ring groove on the outer peripheral surface of the basic cylinder, and forcefully install it in the fixed ring groove. Put on the locking ring. The two ends of the base cylinder are respectively sleeved with an unlocking sliding sleeve and a connecting cylinder, and the two ends of the locking ring respectively extend into the corresponding ports of the unlocking sliding sleeve and the connecting cylinder. The peripheral surface section of the locking ring extending into the end of the u...
