Detailed description of the invention
Below in conjunction with accompanying drawing to the utility model low temperature filling opening sealing ring more changing device be described in further detail.
As shown in Fig. 2～Fig. 9, more changing device of the utility model low temperature filling opening sealing ring, comprising: connecting rod 1, be provided with limit base 2 on the top of connecting rod 1, and on limit base 2, be provided with rotating hole 3; Be provided with chuck 4 in the bottom of connecting rod 1, on chuck 4, be provided with fixed groove 5, and limit base 2, connecting rod 1 and chuck 4 form a tool rack simultaneously.
Fixed groove 5 matches with the profile of low temperature filling opening, in general, fixed groove 5 be shaped as semicircle, together with firmly fixing with the outer wall of low temperature filling opening, be unlikely to come off.
Rotating hole 3, fixed groove 5, filling opening inner chamber and flap 12 are coaxial, and this just means that push rod 6 is balanced through the power of rotating hole 3 downward pressure stretch flaps 12, can deviation.And the internal thread in external screw thread and the rotating hole 3 in push rod 6 outsides matches, push rod 6 can be finely tuned push rod 6 positions own in rising or declining, carry out spacing simultaneously.
And, being provided with rotation hole 7 on the top of push rod 6, crochet hook 8 can insert in rotation hole 7, realizes the rotation of push rod 6.
When use, the first step, unloads circlip for shaft in filling opening with external pliers 15.Second step, the semicircle chuck 4 of tool rack is stuck in the outer step of filling opening, inserts in the rotation hole 7 on push rod 6 tops with crochet hook 8, and the push rod 6 that turns clockwise, backs down filling opening flap downwards.The 3rd step exits crochet hook 8 in rotation hole 7, ticks filling opening pressure ring with needle point 9; The 4th step, ticks sealing ring with needle point 9; Insert in rotation hole 7 and be rotated counterclockwise push rod 6 with crochet hook 8, unload tool rack; The 5th step, is enclosed within new sealing ring 13 on sleeve pipe 11, and sealing ring 13 opening surfaces pack filling opening downwards into.Wherein, the overall diameter of pressure cap 10 coordinates with the diametric clearance of filling opening endoporus, in order to locate pressure cap 10 crush seal circles 13, and the overall diameter matched in clearance of the interior diameter of pressure cap 10 and sleeve pipe 11, be convenient to pressure cap 10 and be inserted in sleeve pipe 11 crush seal circles 13; Meanwhile, the overall diameter of the interior diameter of sleeve pipe 11 and flap 12 installation positions 14 matches, and for locating sleeve 11, prevents that in extrusion process, sealing ring 13 produces deflection; Further, the overall diameter of sleeve pipe 11 is greater than the flap 12 interior diameter of a circles in installation position 14, is convenient to sealing ring 13 and clamp-ons flap 12 installation positions 14, and sealing ring 13 is slipped into by sleeve pipe 11 outsides in the installation position 14 of flap 12, can not damage sealing ring.Then with pressure cap 10, sealing ring 13 is pressed into flap 12, takes out sleeve pipe 11 and pressure cap 10; The 6th step, packs pressure ring into, packs circlip for shaft into external pliers.
