Abstract
The utility model relates to a breathing machine and mechanical equipment field specifically, relate to a concentric device of automatic counter shaft of ejector pin. The utility model discloses a concentric device of automatic counter shaft of ejector pin, related structure (1) that includes ejector pin (3) and receive its control aperture or stroke, wherein on related structure (1) and ejector pin (3) interact's the working face, set up a step and kick off the sphere an of groove (5) and ejector pin (3) one end and cooperate. The utility model provides a pair of the centering mode lets the direct centering of the working face of ejector pin and related structure, and the axiality with regard to directly having guaranteed two parts does not need the indirect centering of spring like this, has simplified production line assembling process.
Description
Technical field
The utility model relates to lung ventilator and technical field of mechanical equipment, particularly, relates to a kind of push rod auto-alignment concentric device.
Background technology
A kind of device utilizing push rod or thimble stretching motion to control aperture with its relational structure or stroke often can be used in lung ventilator or mechanical drive; in this device, push rod or thimble directly act on certain face of its relational structure; this just requires that the centering of push rod or thimble and acting surface will be got well, and can not push up and partially can not knock over.
This kind of device mostly is shown in Fig. 1 at present, for convenience of assembling push rod 3, one end that push rod 3 gos deep into pilot hole is made into sphere or circumferentially rounding, the acting surface of its relational structure 1 is a plane, in cavity, relational structure 1 controls by spring 4 with the right alignment of push rod 3, be enclosed within a disc of relational structure 1 by inner ring one end of spring 4, the other end is enclosed within a disc of push rod guide holder 2, with this centering.In fact and the centering problem of unresolved push rod and acting surface such apparatus structure, only ensure that the right alignment of relational structure and push rod guide holder to a certain extent, and push rod and guide holder are owing to doing relative motion, it coordinates for clearance fit, may deflection in motion process, this just causes push rod may push up inclined relational structure acting surface, occurs control deviation.
Utility model content
The utility model, for above fault of construction, improves this apparatus structure, provides a kind of push rod auto-alignment concentric device.
Push rod auto-alignment concentric device of the present utility model, comprise push rod 3 and be subject to it to control the relational structure 1 of aperture or stroke, wherein, described relational structure 1, with on the acting surface of push rod 3 phase effect, arranges a step and opens rounded channels 5 and match with the sphere of push rod 3 one end.
According to push rod auto-alignment concentric device of the present utility model, preferably, described rounded channels 5 cooperatively interacts with the centre of sphere with both spheres of push rod 3 one end.
According to push rod auto-alignment concentric device of the present utility model, described relational structure 1 can be travel switch class formation.
The utility model the acting surface of relational structure Center step and open rounded channels, its size coordinates with push rod front end, during assembling, push rod contacts can fall into rounded channels with the acting surface of relational structure, for this device of the present utility model, contact because push rod remains with the acting surface of relational structure, therefore spring is exactly now odd parts, can omit.
A kind of centering mode that the utility model provides allows the direct centering of the acting surface of push rod and relational structure, so just directly ensure that the right alignment of two parts, does not need spring centering indirectly, simplifies production line assembling process.
Accompanying drawing explanation
Fig. 1 is the centering device schematic diagram of existing push rod and its relational structure.
Fig. 2 is push rod auto-alignment concentric device schematic diagram of the present utility model.
Reference numeral
1, relational structure 2, push rod guide holder 3, push rod 4, adjusting lever
5, rounded channels
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 2, push rod auto-alignment concentric device of the present utility model, comprise push rod 3 and be subject to it to control the relational structure 1 of aperture or stroke, wherein, described relational structure 1, with on the acting surface of push rod 3 phase effect, arranges a step and opens rounded channels 5 and cooperatively interact with the centre of sphere with both spheres of push rod 3 one end.
Rounded channels is opened at the Center step of the acting surface of relational structure, its size coordinates with push rod front end, during assembling, push rod contacts can fall into rounded channels with the acting surface of relational structure, for this device of the present utility model, contact because push rod remains with the acting surface of relational structure, therefore, without the need to spring centering in addition.
Certainly; the utility model can also have various embodiments; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can openly make various corresponding change and modification according to of the present utility model, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the utility model.
Claims (3)
1. a push rod auto-alignment concentric device, comprise push rod (3) and be subject to it to control the relational structure (1) of aperture or stroke, it is characterized in that, on described relational structure (1) with push rod (3) interactional acting surface, a step is set and opens rounded channels (5) and match with the sphere of push rod (3) one end.
2. push rod auto-alignment concentric device according to claim 1, is characterized in that, described rounded channels (5) coordinates with the centre of sphere with the sphere of push rod (3) one end.
