Abstract
This utility model relates to a kind of Medical gas terminal, comprise base, female connector, spool, ball rack, ball rack spring, ball, overcoat, pressure cap, centring ring, gas plug, submounts connects ball rack by female connector, some row's balls are placed in ball rack, ball rack outside cylinder is connected with female connector inner hole, in female connector endoporus, corresponding ball place has ball hole, and ball rack lower end is provided with boss, is connected with ball rack spring between boss lower surface and base upper surface; Female connector endoporus upper end is fixedly connected with centring ring, removable connection overcoat in the outside cylinder of female connector top, and overcoat lower surface is connected with the boss upper surface aligned contact of the ball rack stretching out female connector, and overcoat outside cylinder and pressure cap are tightly connected.The straight pin that this utility model is used for snap close gas plug changes ball into, and become point cantact from linear contact lay, greatly reduced the frictional force between parts, the size of power when gas plug is inserted reduces greatly.
Description
Technical field
This utility model relates to a kind of Medical gas terminal, particularly relates to a kind of Medical gas terminal meeting DIN13260-2-2004 adopting Cylinder lock with ball buckle structure, high life, convenient for maintaining.
Background technology
Medical gas terminal is the special gas end of a kind of medical field, and the plug of gas equipment (as oxygen inhalation apparatus, negative-pressure suction bottle) can directly insert in Medical gas terminal gets gas.
Traditional Medical gas terminal adopts straight pin as the buckle structure of gas plug, and is rolling friction and the sliding friction of linear contact lay between parts, and frictional force is comparatively large, and the plug of gas plug comparatively has some setbacks.
The service condition of conventional Medical gas terminal is multiplely be connected in parallel on a supply air line, when there being a Medical gas terminal generation problem, need the valve closing on main pipe rail, could keep in repair problematic Medical gas terminal, although although all the other Medical gas terminals be connected in parallel on same steam line do not damage, also cannot use in the problematic Medical gas terminal maintenance period.
Summary of the invention
In order to solve conventional medical gas end Problems existing, this utility model provides a kind of Medical gas terminal, straight pin for snap close gas plug changes ball into, point cantact has been become from linear contact lay, greatly reduce the frictional force between parts, the size of power when gas plug is inserted reduces greatly.
For achieving the above object, the technical solution of the utility model is: a kind of Medical gas terminal, comprise base, female connector, spool, ball rack, ball rack spring, ball, overcoat, pressure cap, centring ring, gas plug, be characterized in: submounts connects ball rack by female connector, some row's balls are placed in ball rack, ball rack outside cylinder is connected with female connector inner hole, in female connector endoporus, corresponding ball place has ball hole, ball rack lower end is provided with boss, is connected with ball rack spring between boss lower surface and base upper surface; Female connector endoporus upper end is fixedly connected with centring ring, removable connection overcoat in the outside cylinder of female connector top, and overcoat lower surface is connected with the boss upper surface aligned contact of the ball rack stretching out female connector, and overcoat outside cylinder and pressure cap are tightly connected.
Be connected with valve seat in base, in valve seat, be connected with spool, above spool, be provided with groove, and between spool and base, valve core spring is housed.
When gas plug inserts after in ball rack, the ball on ball rack enters the groove of gas plug boss both sides, and spool is in closed condition.
When using gas, gas plug inserts to bottom surface in ball rack, and gas plug head face contacts with spool, and spool is in opening.
The beneficial effects of the utility model are:
The straight pin that this utility model is used for snap close gas plug changes ball into, and become point cantact from linear contact lay, greatly reduced the frictional force between parts, the size of power when gas plug is inserted reduces greatly.
Medical gas terminal indoor design of the present utility model has separate valve, when single Medical gas terminal generation problem, only need close the separate valve that inside carries, can keep in repair problematic Medical gas terminal, not affect the normal use of no problem Medical gas terminal.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1: a kind of Medical gas terminal, comprises air inlet pipe 1, base 2, female connector 3, spool 4, valve seat 5, valve core spring 6, ball rack 7, ball rack spring 8, ball 9, overcoat 10, pressure cap 11, centring ring 12, gas plug 13.
Base 2 connects ball rack 7 by female connector 3 above, some row's balls 9 are placed in ball rack 7, ball rack 7 outside cylinder is connected with female connector 3 inner hole, in female connector 3 endoporus, corresponding ball 9 place has ball hole, ball rack 7 lower end is provided with boss, is connected with ball rack spring 8 between boss lower surface and base 2 upper surface; Female connector 3 endoporus upper end is fixedly connected with centring ring 12, removable connection overcoat 10 in the outside cylinder of female connector 3 top, and overcoat 10 lower surface is connected with the boss upper surface aligned contact of the ball rack 7 stretching out female connector 3, and overcoat 10 outside cylinder and pressure cap 11 are tightly connected.Be connected with valve seat 5 in base 2, be connected with spool 4 in valve seat 5, spool 4 is provided with groove above, and between spool 4 and base 2, valve core spring 6 is housed.
As shown in Figure 2, gas plug 13 inserts in this Medical gas terminal, but does not open spool 4, and the gas equipment be now connected on gas plug 13 can provisionally hang on this Medical gas terminal.
As shown in Figure 3, when using gas, gas plug 13 is inserted into penetralia, now spool 4 opens ventilation.
As shown in Figure 4, after gas, pressure cap 11 is pressed downwards, can will extract with gas plug 13.
As shown in Figure 5, when this Medical gas terminal generation problem, available straight screwdriver inserts in the groove of spool 4, is then screwed in base 2.
As shown in Figure 6, when spool 4 is screwed into after in base 2, remaining part can be removed maintenance.
