Abstract
A kind of draft regulator plug-in vacuum table, belongs to draft regulator part device field.There is the defect that cannot rotate adjustment in the vacuum table on existing draft regulator.This utility model comprises vacuum table table body and table bar, vacuum table table body is fixed on table bar upper end, draft regulator main body top is provided with and the hole of showing bar and coordinating, the outer wall of table bar lower end is cylindrical, the hole of main body is unthreaded hole, and the inwall in hole is provided with at least one axis annular groove parallel with centerline hole, in each annular groove, sealing ring is set, sealing ring has ledge with respect to the inwall in described hole, and described table bar coordinates in the hole described in being installed on.This utility model by arranging sealing ring in the hole of draft regulator main body, thereby making to show bar is closely tied in hole, can realize freely rotating of vacuum table, and there is negative pressure in draft regulator bottle, can not produce toward the thrust of extrapolation vacuum table, vacuum table can be stabilized on draft regulator like this, regulates easy to use.
Description
Technical field
This utility model belongs to draft regulator part device field, especially with a kind of draft regulator plug-in vacuum table.
Background technology
Medical draft regulator Main Function is that negative pressure source of the gas is adjusted to required stable negative pressure and carries out flow-control, the upper end of draft regulator arranges vacuum table, thereby observe the negative pressure value regulating in draft regulator bottle by control valve, the table bar of existing vacuum table arranges external screw thread, the top of draft regulator main body arranges the female thread coordinating with this external screw thread, vacuum table by screw-threaded coupling in the top of main body, after vacuum table is locked in draft regulator main body, can only be permanently fixed at an angle, after this cannot carry out again vacuum table to carry out angular adjustment, and the front of vacuum table does not likely have the just main apparent direction facing to draft regulator, if rotation vacuum table, may cause vacuum table gas leakage or vacuum table to damage, therefore very inconvenient in the time regulating the negative pressure value of draft regulator.
Utility model content
The purpose of this utility model is intended to overcome the defect that cannot rotate adjustment that the vacuum table on existing draft regulator exists, and a kind of draft regulator plug-in vacuum table that can carry out to vacuum table multi-angle adjustment is provided.
For this reason, this utility model is by the following technical solutions: a kind of draft regulator plug-in vacuum table, comprise vacuum table table body and table bar, vacuum table table body is fixed on the upper end of table bar, the top of the main body of draft regulator is provided with the hole coordinating with described table bar, it is characterized in that, the outer wall of described table bar lower end is cylindrical, the hole of described main body is unthreaded hole, the inwall in hole is provided with at least one its axis annular groove parallel with centerline hole, in each annular groove, sealing ring is set, sealing ring has ledge with respect to the inwall in described hole, described table bar coordinates in the hole described in being installed on.Annular groove is set on hole wall, sealing ring is set in annular groove, thereby closely cooperate with table bar, having realized table bar can freely rotate, and the interior existence of draft regulator bottle is negative pressure, can not produce his-and-hers watches bar thrust outward, only table bar can be inhaled toward cavity direction in the main body of draft regulator, thereby vacuum table can be stabilized in the main body of draft regulator.
As to technique scheme supplement and perfect, this utility model also comprises following technical characterictic.
The quantity of described annular groove is one.
The quantity of described annular groove is two.
The bottom of described table bar is provided with chamfering, thereby convenient table bar inserts the main body of draft regulator.
The below in described hole is provided with baffle plate, and baffle plate is provided with the through hole connecting with described draft regulator main body inner chamber, thus the degree of depth of can control table bar inserting.
Use this utility model can reach following beneficial effect: this utility model by arranging sealing ring in the hole of draft regulator main body, the head of table bar is arranged cylindrical, thereby making to show bar is closely tied in hole, can realize freely rotating of vacuum table, and the interior existence of draft regulator bottle is negative pressure, can not produce toward the thrust of extrapolation vacuum table, vacuum table can be stabilized in the main body of draft regulator like this, regulates and uses more for convenience.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
Embodiment: as shown in Figure 1, this utility model comprises vacuum table table body 6 and table bar 5, vacuum table table body 6 is fixed on the upper end of table bar 5, the top of the main body 1 of draft regulator is provided with the hole coordinating with described table bar 5, the outer wall of table bar lower end is cylindrical, the bottom of table bar 5 is provided with chamfering, thereby convenient table bar 5 inserts the main body 1 of draft regulator, the hole of described main body 1 is unthreaded hole, the below in hole is provided with baffle plate 2, the inwall in hole is provided with 2 annular grooves 3 that its axis is parallel with centerline hole, the interior sealing ring 4 that arranges of each annular groove 3, sealing ring 4 has ledge with respect to the inwall in described hole, in the hole that described table bar 5 coordinates described in being installed on, annular groove 3 is set on hole wall, the interior sealing ring 4 that arranges of annular groove 3, thereby closely cooperate with table bar 5, having realized table bar 5 can freely rotate, and the interior existence of draft regulator bottle is negative pressure, can not produce his-and-hers watches bar 5 thrust outward, only table bar 5 can be inhaled toward cavity direction in the main body of draft regulator, thereby vacuum table can be stabilized in the main body 1 of draft regulator.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed this utility model.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
