The utility model aims at providing an off-line proportion obstruction device standardizes stifled pipe operation, facilitates the use.

In order to achieve the purpose, the utility model adopts the following technical proposal to realize:

the utility model discloses an off-line proportion blocking device, shell including the tube-shape, be equipped with connecting portion in the middle of the shell top surface, the shell top surface is equipped with four along circumference and blocks the piece, it is 1/4 circular to block the piece, the radius border that blocks the piece is equipped with the pivot, pivot inner rotates connecting portion, the shell lateral wall is run through to the pivot outer end, the pivot is rotated and is connected the shell, the articulated block key of pivot outer end, the shell lateral wall is equipped with the block groove, block groove adaptation block key, be equipped with the wind spring between pivot and the shell, shell bottom internal surface is equipped with the screw thread, the seal section is connected to the shell bottom, the seal section is the tube-shape with the coaxial setting of shell, the material of seal section is elastic material.

Preferably, the rotation shaft is integrally manufactured with the blocking piece.

Preferably, the sealing section is made of silica gel.

Preferably, the shell and the blocking sheet are both made of plastic materials.

Preferably, the inner wall of the shell is circumferentially provided with a plurality of limiting protrusions, and the distance from the limiting protrusions to the top surface of the shell is larger than or equal to the radius of the blocking sheet.

The utility model has the advantages that:

1. the utility model discloses can realize accurate stifled pipe effect, reduce because of the off-line failure risk that the nonstandard operation leads to.

2. The utility model discloses simple structure facilitates the use.

FIG. 1 is a schematic view of the present invention in use;

FIG. 2 is a schematic view of a first embodiment of position A in FIG. 1;

FIG. 3 is a schematic diagram of the second embodiment at position A in FIG. 1.

In the figure: the respirator comprises a shell 1, a connecting part 2, a blocking sheet 3, a rotating shaft 4, a clamping key 5, a clamping groove 6, a sealing section 7 and a respirator tee joint 8.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, in an embodiment, the housing includes a cylindrical housing 1, a connecting portion 2 is disposed in the middle of the top surface of the housing 1, four blocking pieces 3 are circumferentially disposed on the top surface of the housing 1, the housing 1 and the blocking pieces 3 are made of plastic, the blocking pieces 3 are 1/4 circular, a rotating shaft 4 is disposed on a radius edge of the blocking pieces 3, the rotating shaft 4 and the blocking pieces 3 are integrally manufactured, the connecting portion 2 is rotated at an inner end of the rotating shaft 4, an outer end of the rotating shaft 4 penetrates through a side wall of the housing 1, the rotating shaft 4 is rotatably connected with the housing 1, an outer end of the rotating shaft 4 is hinged to a clamping key 5, a side wall of the housing 1 is provided with a clamping groove 6, the clamping groove 6 is adapted to the clamping key 5, a coil spring is disposed between the rotating shaft 4 and the housing 1, when the clamping key 5 is separated from the clamping groove 6, the coil spring makes the blocking pieces 3 perpendicular to the top surface of the housing 1, and a thread is disposed on an inner surface of the bottom of the housing 1.

In order to prevent the blocking piece 3 from contacting the pipeline of the respirator and further leading the blocking piece 3 to be incapable of being perpendicular to the top surface of the shell 1, and causing the nonstandard blocking pipe, a plurality of limiting protrusions are arranged on the inner wall of the shell 1 along the circumferential direction, and the distance from the limiting protrusions to the top surface of the shell 1 is larger than or equal to the radius of the blocking piece 3.

As shown in fig. 1 and 3, the difference between the second embodiment and the first embodiment is that the bottom end of the housing 1 is connected with the sealing section 7, the sealing section 7 is in a cylindrical shape coaxially arranged with the housing 1, the sealing section 7 is made of an elastic material, the sealing section 7 is made of silica gel, and the sealing section 7 is used for reducing a gap between the bottom end of the housing 1 and the three-way pipe 8 of the respirator when pipe plugging is performed, so that air leakage is reduced, and an accurate pipe plugging effect is achieved.

During actual use, the shell 1 is screwed on the respirator tee joint 8 through threads on the inner wall of the shell 1, the sealing section 7 is sleeved on the respirator tee joint 8, the four blocking pieces 3 are perpendicular to the top surface of the shell 1 in an initial state, when pipe blocking is started, the clamping key 5 is fixed in the clamping groove 6 after the clamping key 5 is rotated, the blocking pieces 3 play a pipe blocking role, steps of pipe blocking 1/4 and 1/2 are sequentially completed, and finally, all pipe blocking is achieved, namely, the state shown in the figure is achieved, and off-line operation of a patient is achieved.

Of course, the present invention may have other embodiments, and those skilled in the art may make various corresponding changes and modifications according to the present invention without departing from the spirit and the essence of the present invention, and these corresponding changes and modifications should fall within the protection scope of the appended claims.
