The specific embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined utility model purpose is taked; Below in conjunction with accompanying drawing and preferred embodiment, the specific embodiment and the principle of work of the release valve handling device that proposes according to the utility model is elaborated.
For introducing the utility model difference with the prior art point more intuitively; This part combines accompanying drawing to introduce adopting two kinds of release valve operating mechanisms in the prior art earlier: as shown in Figure 1; In the release valve operating mechanism the earliest; The design of the first release valve pull bar 1 exists other strength to cause and alleviates bad problem because moment arm is shorter during operation; Can know in conjunction with Fig. 1, Fig. 2; The design of the second release valve pull bar 3, layout exist two spaces curved; Exactly because the existence that the space is curved; Generation effect component causes functioning efficiency to reduce, cause alleviating the release valve pull bar to be prone to wipe with near pipe fitting and to bump, move retardance, cause release valve to draw alleviation bad when causing operating.
Fig. 3, Fig. 4 are in the prior art; For improving the improvement project that the first release valve pull bar has been done owing to the short other strength phenomenon that causes of moment arm; Though adopt vertical rocking arm 6 that the release valve pull bar is improved to operating on the alerting ability of release valve 2; But the short phenomenon of release valve pull bar moment arm still exists, and does not also separate the strength of bidding farewell fully and causes the alleviation bad phenomenon; Simultaneously, two spaces of the second release valve pull bar 5 are curved still to be existed, and causes the second release valve pull bar 5 and peripheral pipe fitting to be wiped to bump, move retardance and inefficient phenomenon still to exist.
Below, in conjunction with Fig. 5 to Fig. 7, the release valve handling device that the utility model provides is made concrete introduction.
Release valve handling device as shown in Figure 7, that the utility model provides comprises: release valve pull bar, pivot pin 9, connection lever 10.Wherein, pivot pin 9 is fixed on the car body; Connect lever 10 and be S shape structure, offer the pivot pin mounting hole on the connection lever, through the pivot pin mounting hole; To connect lever 10 and be set on the pivot pin 9, the connection lever after the installation is horizontal layout, and is as shown in the figure; Connect lever 10 and comprise two free ends, an end up, an end is down; An end up is connected with release valve, and an end down is connected with the release valve pull bar.
After having adopted the utility model, being arranged on can both flexible operating apart from release valve 2 release valve pull bars near or far away.As shown in Figure 5; The first release valve pull bar 7 in the present embodiment is arranged in car body one side nearer apart from release valve 2; The second release valve pull bar 8 is arranged in car body one side far away apart from release valve 2, and the first release valve pull bar 7, the second release valve pull bar equal 8 and the same end that is connected lever 10 connect.
Because the connection lever 10 of S shape structure is with having isolated big activity space between release valve pull bar that is attached thereto and the release valve 2; And the first release valve pull bar 7, the second release valve pull bar equal 8 and the same end that is connected lever 10 connect, and make win release valve pull bar 7 and the second release valve pull bar 8 can both place the same side of release valve 2.As shown in Figure 6; Such layout can make the second release valve pull bar 8 be planar structure and arrange; Eliminated the curved structure in space; Make that exist the functioning efficiency that is caused to reduce, cause alleviating the release valve pull bar is prone to wipe with near pipe fitting and bumps, move retardance because of the space is curved, causes release valve to draw the bad problem of alleviation to be solved at all.
For the length that connects lever 10; Preferably; The length that connects lever 10 is arranged to: towards a side of release valve pull bar and the level interval between the release valve pull bar periphery pipe fitting, in operating process, can wiping not take place with further assurance release valve pull bar and bump with peripheral pipe fitting greater than release valve 2.
For the connection mode between each assembly in the utility model; Preferably; With the release valve pull bar be connected between the lever 10, connect between lever 10 and the pivot pin 9, be connected between lever 10 and the release valve 2; All connect, when making it guarantee each assembly flexible operating, strengthen each assembly bonded assembly degree of reliability through spring cotter.
When implementing the link operation, pulling release valve pull bar, connecting lever 10 can rotate around pivot pin 9, thereby to controlling with being connected lever 10 bonded assembly release valves 2, release valve 2 air drafts is alleviated.
It should be noted last that; The above specific embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to instance the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
