Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Specific embodiment described herein is only in order to explain the utility model, and is not used in restriction the utility model.In addition,, in each mode of execution of described the utility model, involved technical characteristics just can combine mutually as long as do not form each other conflict.
Schematic diagram when being respectively the utility model sealing and connecting as Fig. 1 and Fig. 2, the utility model comprises press base 1, the fixed base 3 that an inside is provided with cavity is installed in press base 1, in the cavity of fixed base 3, be provided with one and mate the sliding sleeve 4 that close contact can slide in its inside with it, between the cavity of sliding sleeve 4 and fixed base 3, be provided with an O-ring seal 18, can between sliding sleeve 4 and fixed base 3 inwalls, form good sealed environment.The center of sliding sleeve 4 is provided with a bearing pin 5 being connected with fixed base 3 bottom thread, and bearing pin 5 middle parts are provided with an annular inner sealing mechanism, and this inner sealing mechanism is made up of annular flange flange 11, plane sealing packing ring 12 and baffle plate 13.Annular flange flange 11 is fixed on the excircle of bearing pin 5, and plane sealing packing ring 12 is coated in annular flange flange 11, and the lower end surface of annular flange flange 11 is protruded in the bottom of plane sealing packing ring 12.Baffle plate 13 is fixed on plane sealing packing ring 12 by a bolt 14, plane sealing packing ring 12 and annular flange flange 11 is compressed, and give a downward support force to plane sealing packing ring 12, prevents that plane sealing packing ring 12 is out of shape and loses seal action.Bearing pin 5 has a Returnning spring 9 in 11 times square sets of annular flange flange, and sliding sleeve 4 inwalls are provided with and protrude the annular boss 10 being connected between plane sealing packing ring 12 lower end surfaces and Returnning spring 9 upper-end surfaces to center, and they form a good seal space each other.Top at sliding sleeve 4 is fixed with top sealing mechanism, and top sealing mechanism is made up of the gland 15 and the lip seal packing ring 16 that are arranged on sliding sleeve 4 tops.The top inner wall of sliding sleeve 4 is provided with an annular draw-in groove 17, and lip seal packing ring 16 is arranged in draw-in groove 17.Lip seal packing ring 16, between gland 15 and the top inner wall of sliding sleeve 4, forms good seal space between.The upper-end surface of the upper-end surface of gland 15 and sliding sleeve 4 maintains an equal level, and the top of lip seal packing ring 16 protrudes from the upper-end surface of gland 15, and the upper-end surface level height of gland 15 is higher than the upper-end surface of press base 1.Be provided with a suction port 6 communicating with sliding sleeve 4 cavitys in the bottom of fixed base 1, gland 15 centers are provided with an air outlet 8 communicating with sliding sleeve 4 cavitys.
Working principle of the present utility model is as follows: before press work, and annular boss 10 and plane sealing packing ring 12 lower end surfaces and Returnning spring 9 upper-end surface close contacts, lower contact is closed state.In the time starting working, shuttle table 2 moves to working position, i.e. the top of press base 1, and the jack-up cylinder of shuttle table 2 falls, its lower end surface is by the lip seal packing ring 16 of protrusion and press base 1 upper-end surface to pressing down, and lip seal packing ring 16 drives sliding sleeve 4 to move downward.Annular boss 10 lower end surfaces on sliding sleeve 4 by Returnning spring 9 to pressing down, the upper-end surface of annular boss 10 separates with plane sealing packing ring 12, between suction port 6 and air outlet 8, be communicated with, gas enters into press inside by the press suction port 7 being positioned on shuttle table 2 being connected with air outlet 8 on press base 1, and press is started working.After press work is complete, shuttle table 2 is by jack-up, its lower plane separates with the upper-end surface of press base 1, Returnning spring 9 promotes sliding sleeve 4 and is moved upwards up to origin-location, annular boss 10 and plane sealing packing ring 12 lower end surfaces and Returnning spring 9 upper-end surface close contacts, continue to form a good seal space, no longer conducting between suction port 6 and air outlet 8, lower contact, again in closed state, is waited for the use of next time working.
The above; be only embodiment of the present utility model, it should be pointed out that any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.
