Detailed Description
For a better understanding and appreciation of the invention, reference will now be made to specific embodiments thereof in which the invention is illustrated in detail; the illustrated embodiments are merely illustrative of the present invention and are not intended to limit the scope of the invention.
As shown in figure 1, the quick joint device for the water cooling pipe in the ejector rod capable of transferring the axial force comprises an inner joint body 1, a clamping plate 2, a sealing ring 3, a split pin 4, a rotary pin shaft 5 and an outer joint body 6; the front end of the outer joint body 6 is provided with a guide taper hole and a cylindrical sealing surface, the front end of the inner joint body 1 is provided with a guide taper and a cylindrical sealing surface, so that the quick installation and the effective sealing are convenient, and the guide taper hole of the outer joint body 6 is matched with the guide taper of the inner joint body 1; the clamping plates 2 are three, and the sealing rings 3 are placed on the cylindrical sealing surfaces of the outer joint body 6 and the inner joint body 1 for effective sealing; the three clamping plates 2 are connected with the outer joint body 6 into a whole through the rotating shaft 5, the rotating shaft 5 is provided with a cotter pin 4, and the cotter pin 4 is used for preventing the rotating shaft 5 from falling off; the circular arc boss of the clamping plate 2 is tightly clamped with the inner joint body 1 by utilizing the fixing of the cylindrical hole in the ejector rod, so that the three clamping plates 2 are connected and can transfer the axial force; the quick connector device axially slides in the ejector rod hole, so that the ejector head removing and locking functions are realized.
According to the quick joint device for the water cooling pipe in the ejector rod capable of transmitting the axial force, when the ejector rod is disassembled (as shown in figure 2), the rod 8 leaves the shaft head 7 of the trolley, and the three clamping plates 2 are not fixed through cylindrical holes and automatically open under the action of self weight; the ejector rod water pipe can be automatically separated, and quick disassembly is realized; when the clamping plate is opened, the maximum diameter of the head inclined guide is smaller than the diameter of the inner hole of the ejector rod; when a new ejector rod is installed (as shown in figure 3), the inner joint body 1 can conveniently enter the outer joint body 6 under the guidance of the front cone, the arc groove of the inner joint body 1 reaches the boss position of the clamping plate 2, the cylindrical hole of the ejector rod properly reaches the head of the clamping plate 2 for oblique guidance, and the ejector rod can be smoothly installed into the head of the trolley shaft, so that the quick installation is realized.
