In this structure, the elastic plate is pressed and is produced and forms and supply connecting portion 3 to drive buckling portion 2 and stretch into in expanding recess 11 from positive notch and rotate, when rotating in expanding recess 11 and forming vertical spacing to buckling portion 2, the downforce releases, the elastic plate rebound detains in expanding recess 11 positive notch, thereby reach the location and stop the effect of changeing, further retaining member 7 forms driving force and drives connecting portion 3 and form ascending pulling force, pulling force can drive buckling portion 2 to buckle expanding recess 11 and accomplish locking at last, buckling portion 2 can stretch into from expanding recess 11's positive notch and form forward direct mount when the installation, very big improvement the convenience of installation, elastic plate resilience can drive buckling portion 2 and interior expanding recess 11 and hug closely and reach the function of location rotation prevention after rotating, make buckling portion 2 be in the locate state with the help of external force in locking process, the convenience of installation has been improved greatly, and is simple in structure, design benefit.
In this embodiment, the elastic plate is sleeved on the connecting portion 3 and rotates along with the connecting portion 3. In this structure, the elastic plate rotates along with the connecting portion 3, that is, the elastic plate is deformed while being pressed and rotates along with the connecting portion 3, and finally is buckled into the inner expanding groove 11.
In this embodiment, the elastic plate is provided with a mounting hole 48, the mounting hole 48 is provided with a clamping platform 481 at the inner edge, the connecting portion 3 is provided with a clamping groove 33, the elastic plate is mounted on the connecting portion 3 in a sleeved manner, and the clamping platform 481 is in fit and clamping connection with the clamping groove 33. In this structure, through the cooperation joint of clamping platform 481 and draw-in groove 33, realized the fixed relation of elastic plate and connecting portion 3 for the elastic plate can rotate along with connecting portion 3, can receive its downforce to produce deformation again, its simple structure, design benefit.
Example 7:
as shown in fig. 16 and 17, the present invention is applied to a seventh embodiment of a coupling member for an internally expanding grooved tube, which is substantially the same as embodiment 6 except that: in this embodiment, the positioning piece 4 is an elastic plate connected to the connecting portion 3, when the connecting portion 3 is pressed down to rotate, the elastic plate is elastically deformed, and after rotation, the elastic plate rebounds to drive the fastening portion 2 to move upwards through the connecting portion 3 and cling to the inner expanding groove 11 to form vertical and rotary positioning. The elastic plate is pressed to generate and form the connecting part 3 to drive the buckling part 2 to extend into the inner expansion groove 11 from the positive notch to rotate, when the connecting part 2 is vertically limited by the inner expansion groove 11, the downward pressure is relieved, the elastic plate rebounds to drive the buckling part 2 to move upwards to be clung to the inner expansion groove 11 through the connecting part 3, so that the positioning rotation stopping effect is achieved, the buckling part 2 is in a positioning state without external force in the locking process, the installation convenience is greatly improved, and the structure is simple and the design is ingenious.
In this embodiment, the elastic plate is sleeved on the connecting portion 3 and does not rotate along with the connecting portion 3. In this structure, the elastic plate can only receive the connecting portion 3 down force and not receive the rotation torsion of connecting portion 3, can realize receiving its down force deformation equally and kick-back and drive the effect of back-up.
In this embodiment, the elastic plate is provided with a sleeve hole 48, the connecting portion 3 is provided with a pressing table 34, the elastic plate is sleeved on the connecting portion 3, and the pressing table 34 is pressed at the edge of the sleeve hole 48. In the structure, when the connecting part 3 is pressed down, the pressing table 34 presses the edge of the sleeving hole 48, so that the elastic plate is driven to deform, and when the elastic plate rebounds, the sleeving hole 48 of the elastic plate acts on the pressing table 34 reversely, so that the connecting part 3 drives the metal buckle head 23 to move upwards to realize back buckling.
While the invention has been described in terms of preferred embodiments, it is not intended to be limiting. Many possible variations and modifications of the disclosed technology can be made by anyone skilled in the art, or equivalent embodiments with equivalent variations can be made, without departing from the scope of the invention. Therefore, any simple modification, equivalent variation and modification of the above embodiments according to the technical substance of the present invention shall fall within the scope of the technical solution of the present invention.
