Abstract
The utility model relates to an air chamber sealer for a link, which comprises an air chamber body, a link and a through hole. The utility model is characterized in that the link is positioned in the through hole which is arranged on the air chamber body; a diaphragm is sheathed on the link; the outer margins of the diaphragm are fixed in a sinking groove positioned on the air chamber body; by pressing plates; the upper and the lower surfaces of the inner margins of the diaphragm are fixed on the link by the two pressing plates; the diaphragm is elastic materials. Outer rings of two pressing plates which are fixed on the link are provided with a wedge surface; the center of the diaphragm, corresponding to the wedge surface of the pressing plates, is provided with a corresponding trapezoid circular table. The utility model has the advantages that the utility model has the functions of sealing, and the motion of the link can not be influenced.
Description
Technical field
The utility model relates to a kind of seal arrangement, particularly a kind of air chamber seal arrangement that is used for connecting rod.
Background technique
Order is the use of water pump for convenience in the water pump manufacturing industry, a lot of water pumps carries vacuum pump so that when water pump is brought into use the air in the water pump is discharged, and the power of vacuum pump is directed to the main shaft of water pump, usually utilize a cover bent axle connecting rod means that a reciprocal straight line power is taken out in the rotation of the main shaft of water pump, utilize connecting rod to promote vacuum pump, therefore just there is the problem of a sealing connecting rod in air chamber, but existing sealing configuration more complicated, and the structure that has has strengthened sealing the motion that has still hindered connecting rod, needing to be resolved hurrily to seal connecting rod, can guarantee the reciprocating air chamber seal arrangement that is used for connecting rod of connecting rod again.
Summary of the invention
The purpose of this utility model is to solve to seal the existing the problems referred to above of connecting rod in the prior art in air chamber, provides a kind of and can seal connecting rod, can guarantee the reciprocating air chamber seal arrangement that is used for connecting rod of connecting rod again.A kind of air chamber seal arrangement that is used for connecting rod of the utility model design, comprise air chamber body, connecting rod, through hole, it is characterized in that: connecting rod is arranged in the through hole on the air chamber body, one diaphragm case is arranged on connecting rod, the outward edge of barrier film is fixed in the deep gouge on the air chamber body by pressing plate, and the upper and lower surface of the inward flange of barrier film is fixed on by two pressing plates that barrier film is an elastic material on the connecting rod.Face is carved in the outer ring that is fixed on two pressing plates on the connecting rod, with respect to the central authorities of the face of the carving barrier film of pressing plate corresponding trapezoidal round platform is arranged.The utility model has the advantages that the effect that can play sealing does not influence link motion again.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
Embodiment
Comprise air chamber body 1, connecting rod 2, through hole 3 among the figure, it is characterized in that: connecting rod 2 is arranged in the through hole 3 on the air chamber body 1, there is a barrier film 4 to be enclosed within on the connecting rod 2, the outward edge of barrier film 4 is fixed in the deep gouge 6 on the air chamber body 1 by pressing plate 5, the upper and lower surface of the inward flange of barrier film 4 is fixed on the connecting rod 2 by two pressing plates 7,8, and barrier film 4 is an elastic material.Face 9 is carved in the outer ring that is fixed on two pressing plates 7,8 on the connecting rod 2, and with respect to the face of carving 9 of pressing plate 7,8, there is corresponding trapezoidal round platform 10 in the central authorities of barrier film 4.Because the outer ledge of barrier film 4 is clamped on the deep gouge 6 of air chamber body 1 by the pressing plate 5 of rigidity, and inboard central authorities are fixedlyed connected with connecting rod 2 by pressing plate 7,8 clampings of two rigidity, simultaneously there is the face of carving 9 outer ring of two pressing plates 7,8 and there is corresponding trapezoidal round platform 10 in the central authorities of barrier film 4, therefore can guarantee to be connected firmly after stepping up, because the elasticity of barrier film 4 is bigger, when the inboard central authorities of fixedlying connected with connecting rod 2 move reciprocatingly along with connecting rod 2, outer ledge can maintain static, and the effect that can play sealing does not influence connecting rod 2 motions again.
Claims (3)
1, a kind of air chamber seal arrangement that is used for connecting rod, comprise air chamber body, connecting rod, through hole, it is characterized in that: connecting rod is arranged in the through hole on the air chamber body, one diaphragm case is arranged on connecting rod, the outward edge of barrier film is fixed in the deep gouge on the air chamber body by pressing plate, and the upper and lower surface of the inward flange of barrier film is fixed on the connecting rod by two pressing plates
