Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to Fig. 1 to Fig. 3, what is provided in figure is a kind of flap valve structure, including flap valve seat 100 and is hinged on flap valve seat The side of door-slapping cover 200 on 100, the hinge joint far from door-slapping cover 200 in the aperture of flap valve seat 100 110 is provided at least One flap valve buffering mechanism 300.Consider the factors such as stable structure, stress balance arrangement, it is separate in the aperture of flap valve seat 100 110 The left and right two small angular positions in the both ends of the side of the hinged end of door-slapping cover 200 i.e. its bottom are respectively arranged flap valve buffering dress Set 300.
Referring to Fig. 4 and combine Fig. 1 to Fig. 3, flap valve buffering mechanism 300 include buffer installation pedestal 310, buffer 320, It is left and right to tune nut 330a, 330b and ram 340.Buffer installation pedestal 310 include base board (not shown) with And it is arranged at intervals on the installation riser 311,312 on base board, it installs and offers an installation through-hole respectively on riser 311,312 311a、312a.Left and right rotation positioning threads 321a, 321b, left and right rotation are provided on the outer surface of the cylinder part of buffer 320 Positioning threads 321a, 321b are to be symmetrically distributed on the outer surface of cylinder part with the center of buffer 320, buffer 320 Cylinder part is supported in installation through-hole 311a, 312a of installation riser 311,312 and its both ends extends respectively to installation riser 311,312 outside.Left and right nut 330a, 330b of tuning is the symmetrical nut of a pair of of left-right rotary, and rotation respectively is located at buffer Left and right rotation positioning threads 321a, 321b of 320 cylinder part are upper and bear against in the lateral surface for installing riser 311,312 On.It rams and 340 is arranged on 322 end of piston rod of buffer 320.In this way, by adjust it is left and right tune a nut 330a, 330b can be adjusted the installation site of buffer 320.
In the present embodiment, for buffer 320 preferably by automatic compensation type oil buffer, automatic compensation type oil pressure is slow The basic functional principle for rushing device is to ram 340 after by the whereabouts of door-slapping cover 200 shock pressure on buffer 320, and piston rod 322 squeezes The hydraulic oil in working chamber (rodless cavity), compression reseting spring 323 are pressed, while hydraulic oil enters shoe cream room from hole (has bar Chamber).After flap valve is opened, the spring 323 that is reset of piston rod 322 is pushed into initial position, completes a working cycles.According to calculating Impact force selects suitable buffer, the cushion stroke of buffer 320 to be selected as the range of 10mm~20mm.
It is at an angle between the axis and horizontal plane of buffer 320 so that when on the piston rod 322 of buffer 320 Ram 340 when being contacted with the inner side end of door-slapping cover 200, the axis of buffer 320 is perpendicular to the inner end of door-slapping cover 200 Face rams 340 on the piston rod 322 to ensure the vertical positive cushion at collision of door-slapping cover 200 320.
One is provided at the position of 340 contacts of raming on piston rod 322 of the door-slapping cover 200 with buffer 320 to ram Gasket 210 ensures that the surface of door-slapping cover 200 is injury-free.
Flap valve seat 100 is towards a rubber water-proof sealing strip 400 is provided on the end face of door-slapping cover 200, when door-slapping cover 200 closes When closing, flap valve buffering mechanism 300 is so that door-slapping cover 200 is not directly contacted with flap valve seat 100, but stops to the rubber on flap valve seat 100 Water retaining and sealing strip 400 possesses certain decrement so that sealing is formed between door-slapping cover 200 and flap valve seat 100.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model Claimed range is defined by the appending claims and its equivalent thereof.
