Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model technological scheme being carried out detailed description, with purpose, scheme and the effect of further understanding the utility model, but is not the restriction as the utility model accompanying claims protection domain.
Consult the structural drawing of the vacuum sealing device of Fig. 1 the utility model, as shown in the figure, the vacuum sealing device of the utility model comprises housing 10 and places the sealed knot valve body 20 of housing inner chamber 13 slidably.Have on the housing 10 first bleeding point 11 and second bleeding point, 12, the first bleeding points 11 and second bleeding point 12 all with housing inner chamber 13 UNICOMs, and first bleeding point 11 is used to connect vacuum pump, second bleeding point 12 is used to connect the product that need vacuumize.Sealed knot valve body 20 comprises connecting rod 21, spool 22 and rotatable handle 24, and connecting rod 21 has on first connecting end 211 and second connecting end, 212, the second connecting ends 212 and is connected with the shutoff (not shown), and second connecting end 212 is preferable through being threaded with shutoff; Be arranged with elastic element 23 on the spool 22; Spool 22 has first groove part 221, second groove part 222 and bump 223; First connecting end 211 is placed in first groove part 221; A connection piece 25 passes first groove part 221 and with first connecting end 211 connecting rod 21 is connected with spool 22; Rotatable handle 24 has one and connects rod end 241, connect rod end 241 be placed in second groove part 222 and with second groove part, 222 drive fits so that rotatable handle 24 is connected with spool 22, bump 223 is between first groove part 221 and second groove part 222.Preferably; Housing inner chamber 13 is provided with an installation base 26 away from the position of second bleeding point 12; Elastic element 23 and is provided with seal ring 27 between installation base 26 and the housing 10 between installation base 26 and bump 223, so that installation base 26 is tightly connected with housing 10.
