Abstract
The invention relates to a pull rod for an air vent middle sleeve. The pull rod for the air vent middle sleeve comprises a pull rod, wherein the pull rod is a double-arm parallel pull rod formed by two pull rods; a hanger is arranged at the front end of the double-arm parallel pull rod; fastening bolts are arranged at the tail ends of the two pull rods for adjusting the openness of the hanger at the front end. The pull rod can save the dismounting time by shortening the time for dismounting a middle sleeve from about 40 minutes to about 10 minutes and reduces the pull rod slip phenomenon and potential safety hazards; moreover, damping down caused by the faults of the middle sleeve is shorted, thereby reducing damping down delay and improving the production efficiency.
Description
Technical field
The present invention relates to air port, a kind of stokehold service kit, overlap pull bar in a kind of specifically air port.
Background technology
Being enclosed within the back of breaking down in the air port, stokehold and changing, not having special tool in the past, can only be by little cover pull bar, changes one in cover need 40 minutes, and use little cover pull bar not skid to occurring easily because of size, influence the replacing time.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of prior art, provide a kind of can be convenient for changing seal in the instrument of cover, have the characteristics simple to operate that save time.
In order to solve above technical problem; The present invention provides in a kind of air port and overlaps pull bar, comprises pull bar, and said pull bar is the both arms parallel draw bar that two pull bars constitute; The front end of said both arms parallel draw bar has hook, at the terminal opening and closing degree that holding bolt is installed in order to adjustment front end hook of two pull bars.
The technical scheme that the present invention further limits is: overlap pull bar in the aforesaid air port, the hook direction of the front end of said both arms parallel draw bar is served as reasons, and introversion is outer digs.
The invention has the beneficial effects as follows: adopt the present invention to have saved the take-down time, shorten to about 10 minutes in about 40 minutes by original dismounting one cover needs of merely hitting; And reduced the phenomenon of pull bar slippage, also reduced the appearance of potential safety hazard simultaneously; Shortened because of in the damping down that causes of set of fault, reduced damping down and mistaken, enhance productivity.
Description of drawings
Fig. 1 is intended to for structure iron of the present invention.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Embodiment 1
Overlap pull bar in a kind of air port that present embodiment provides; Structure is as depicted in figs. 1 and 2; Comprise the both arms parallel draw bar that two pull bars 1 constitute, the front end of both arms parallel draw bar has hook 2, at the terminal opening and closing degree that holding bolt 3 is installed in order to adjustment front end hook of two pull bars; The hook direction of the front end of both arms parallel draw bar is served as reasons, and introversion is outer digs.
Present embodiment becomes the both arms parallel draw bar with tuyere small sleeve single armed pull bar optimization design; And install holding bolt additional at two parallel double arm brace ends; Tightening bolt when in pull bar front end hook catches on, overlapping both sides of the edge; The pull bar phenomenon of trying to shirk responsibility the time appears in cover never again in drawing, and the time ratio of cover shortens originally greatly in leaving behind.
Except that the foregoing description, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
