Detailed Description

The invention will be further described with reference to the following figures and examples:

as shown, the present invention provides a connector and a pipe plug, which comprises a connector 1 and a pipe plug 2, wherein the connector 1 is inserted into the pipe plug 2. The connector 1 comprises a connecting seat 12 and a connecting taper rod 11, wherein the connecting seat 12 and the connecting taper rod 11 are of an integral structure. A circle of groove 13 is arranged at the joint of the connecting conical rod 11 and the connecting seat 12. The upper part of the connecting taper rod 11 is in a conical structure, the lower part of the connecting taper rod 11 is in a multi-prismatic structure 112, and two salient points 111 are arranged on the outer ring of the upper opening of the connecting taper rod 11. The pipe plug 2 comprises a plug body 21, a locking button 22, a button rotating shaft 23 and a reset spring piece 24, wherein the locking button 22 is arranged on one corner of the end part of the plug body through the button rotating shaft 23. The inner side of the reset spring piece 24 is clamped in the spring groove 25 of the plug body 21, the outer end of the reset spring piece is propped against the locking button 22, and the locking hook 28 of the locking button 22 is hooked in the groove 13.

The corner of the plug body end is provided with a locking groove 27, and the locking button 22 is arranged in the locking groove 27 on the corner of the plug body end. The cock body of locking groove 27 both sides on respectively be equipped with a pair of bayonet socket, be first bayonet socket and 26 second bayonet sockets respectively, first bayonet socket 26 and second bayonet socket symmetry, locking button 22 on be equipped with the shaft hole, locking button 22 pass through the shaft hole cover on button rotation axis 23, button rotation axis 23 two ends block respectively in calorie in first bayonet socket 26 and second bayonet socket. The multi-prismatic structure 112 is an octagonal structure. The salient points 111 are arc salient points.

The length of the connecting conical rod 11 is slightly longer than that of the pipe plug 2. In the clamping state of the connector 1 after being inserted into the pipe plug 2, the convex point 111 on the connecting conical rod 11 is clamped on the upper edge 29 of the pipe orifice of the pipe plug 2.

The utility model discloses a connection method is: the plug 21 is first pressed into the end of the square metal tube 3 having the mounting groove 31 by pressure, and the plug 21 is locked in the square metal tube 3 by the protrusions 211 on the plug. Then the connecting taper rod 11 is inserted into the pipe plug 2, so that the two salient points 111 on the outer ring of the upper opening of the connecting taper rod 11 are clamped on the upper edge 29 of the pipe opening of the pipe plug 2, and the conical structure on the upper part of the connecting taper rod 11 is in seamless fit with the inner conical cavity of the pipe plug 2.
