Abstract
The utility model discloses a kind of side seal well lid, comprise well lid and well seat, described well lid is loaded in well seat, sealing ring is provided with between the outer circumference surface of described well lid and well seat inside wall, the inside wall of described well seat is in setting perpendicular with horizontal plane, the outer ring surface that described sealing ring contacts with well seat inside wall is wide at the top and narrow at the bottom being obliquely installed, and the inner ring surface of described sealing ring is provided with the groove that well lid outer circumference surface can be wrapped up completely in the inner.Adopt said structure, the utility model provides a kind of sealing effectiveness better and be convenient to the side seal well lid that well lid opens again.
Description
Technical field
The utility model relates to a kind of well lid.
Background technology
At present, well lid on road surface is connected and composed by well lid and well seat usually, well lid is loaded in well seat, and the sealing between well lid and well seat mainly contains two kinds of modes: a kind of is be arranged on the lower surface of well lid by sealing ring, this sealing means not only waterproof effect is poor, but also easily cause between well lid outer circumference surface and well seat inside wall and leak sandstone, thus cause a large amount of sandstone to be piled up in well seat, it is very inconvenient to clear up; Another kind is middle part sealing ring being flush-mounted in well lid outer circumference surface, although this sealing means can improve waterproof effect greatly, but long-time the laminating completely with well seat inside wall of the outer ring surface of sealing ring contacts, the outer ring surface of sealing ring and well seat inside wall can be caused to be bonded together, thus to cause well lid to be difficult to be turned on again.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of sealing effectiveness better and be convenient to the side seal well lid that well lid opens again.
For achieving the above object, the utility model provides a kind of side seal well lid, comprise well lid and well seat, described well lid is loaded in well seat, sealing ring is provided with between the outer circumference surface of described well lid and well seat inside wall, the inside wall of described well seat is in setting perpendicular with horizontal plane, and the outer ring surface that described sealing ring contacts with well seat inside wall is wide at the top and narrow at the bottom being obliquely installed, and the inner ring surface of described sealing ring is provided with the groove that well lid outer circumference surface can be wrapped up completely in the inner.
The beneficial effects of the utility model are: adopt said structure, because sealing ring is arranged between the outer circumference surface of well lid and well seat inside wall by the utility model, therefore favorable sealing property, simultaneously, because the outer ring surface that described sealing ring contacts with well seat inside wall is wide at the top and narrow at the bottom being obliquely installed, therefore make the outer ring surface of described sealing ring be actually crossing with well seat inside wall to contact, thus also just make described sealing ring outer ring surface only has this joining contact with well seat inside wall, and then also just effectively avoid sealing ring outer ring surface and well seat inside wall to be bonded together, be convenient to well lid again open, and the inner ring surface of described sealing ring is wrapped on well lid outer circumference surface completely, not only can promote the overall sealing performance of well lid further, but also make the handling between sealing ring and well lid also easier, be convenient to change sealing ring when people keep in repair.
The lower surface that the utility model can be set to described well lid further is also fixed with a wear washer, described wear washer is also provided with and extends radially outwardly and form the radial elongated end hidden sealing ring lower axial end face, and on the inside wall of described well seat, correspondence is provided with and can forms with described wear washer lower axial end face the shoulder rank abutted.
Adopt said structure, not only effectively can improve the abrasion resistance of well lid and sealing ring, but also described well lid and sealing ring can be combined more securely.
The utility model also can be set to be fixed by sunk screw between described wear washer and well lid lower surface further, the radial elongated end end face of described wear washer is also provided with the anti-skidding burr that can contact with described sealing ring lower axial end face.
Adopt said structure, the anti-skidding burr set up, relative sliding when can effectively avoid sealing ring to be squeezed, thus sealing ring and wear washer are linked together better.

Detailed description of the invention
Give a kind of side seal well lid as shown in Figure 1, 2, 3, comprise well lid 1 and well seat 2, described well lid 1 is loaded in well seat 2, sealing ring 3 is provided with between the outer circumference surface 11 of described well lid 1 and well seat inside wall 21, the inside wall 21 of described well seat 2 is in setting perpendicular with horizontal plane, the outer ring surface 31 that described sealing ring 3 contacts with well seat inside wall 21 is obliquely installed in wide at the top and narrow at the bottom, the inner ring surface 32 of described sealing ring 3 is provided with the groove 321 that well lid outer circumference surface 11 can be wrapped up completely in the inner.The lower surface of described well lid 1 is also fixed with a wear washer 4, fixed by sunk screw 5 between described wear washer 4 and well lid 1 lower surface, described wear washer 4 is also provided with and extends radially outwardly and form the radial elongated end 41 hidden sealing ring 3 lower axial end face, and radial elongated end 41 end face of described wear washer 4 being also provided with the anti-skidding burr 411 that can contact with described sealing ring 3 lower axial end face, on the inside wall 21 of described well seat 2, correspondence is provided with and can forms with described wear washer 4 lower axial end face the shoulder rank 22 abutted.
Adopt said structure, because sealing ring 3 is arranged between the outer circumference surface 11 of well lid 1 and well seat inside wall 21 by the utility model, therefore favorable sealing property, simultaneously, because the outer ring surface 31 that described sealing ring 3 contacts with well seat inside wall 21 is obliquely installed in wide at the top and narrow at the bottom, therefore make the outer ring surface 31 of described sealing ring 3 be actually to contact with well seat inside wall 21 is crossing, thus also just make described sealing ring outer ring surface 31 only has this joining contact with well seat inside wall 21, and then also just effectively avoid sealing ring outer ring surface 31 and well seat inside wall 21 to be bonded together, be convenient to well lid 1 again open, and the inner ring surface 32 of described sealing ring 3 is wrapped on well lid outer circumference surface 11 completely, not only can promote the overall sealing performance of well lid further, but also make the handling between sealing ring 3 and well lid 1 also easier, be convenient to change sealing ring 3 when people keep in repair.
