Abstract
The invention discloses a bucket body and bucket cover sealing device for a sprayer. The bucket body and bucket cover sealing device comprises a bucket body and a bucket cover, wherein a connecting ring is arranged in the bucket cover; and an internal thread is formed in the connecting ring, and is connected with an external thread of the mouth part of the bucket body. The bucket body and bucket cover sealing device is characterized in that: the outer wall of the mouth part of the bucket body is provided with a concave ring; an O-shaped ring is arranged in the concave ring; the inner wall of the connecting ring of the bucket cover is provided with an inclined plane; and the inclined plane is contacted with the O-shaped ring. When the bucket cover is screwed downwardly to a larger extent, the O-shaped ring is extruded more tightly along with the reduction in the diameter of the inclined plane and is flattened slightly, so that the contact area between the O-shaped ring and the inclined plane is increased, and a good sealing effect is achieved; and meanwhile, when air pressure exists in a bucket, the O-shaped ring on the outer side of a bucket mouth can be better contacted with the sealing surface of the bucket cover even though the bucket mouth is deformed and expands outwards. During cover opening, the bucket cover is rotated upwards, so that the O-shaped ring slowly returns to an original state slowly, the contact area between the O-shaped ring and the inclined plane is reduced gradually, and the cover is opened easily in a labor-saving way.
Description
Technical field
The present invention relates to sprayer, particularly relate to a kind of sprayer staving and bung sealing device.
Background technology
Sprayer is when work, and will keep-up pressure in the staving just to make agricultural chemicals be able to outside injection, therefore guarantees that the sealing of sprayer is crucial.The staving and the sealing device between the bung of existing sprayer mostly are through being shaped on the sealing ring mounting groove in the bung lower end; It is the sealing ring on plane that the lower surface is installed in mounting groove, and after bung and staving were tightened, sealing ring contacted with the upper surface of staving oral area and reaches sealing purpose; But this class formation; Often big because of sealing ring and staving oral area contact area, the locking of bung or unscrew all very painstakingly, effect is bad; A kind of in addition is on the outer wall of staving oral area, sealing ring to be installed, and sealing ring contacts with the inwall of bung installing ring, and this sealing structure circle and bung contact-making surface are little, and it is poor to produce sealing effectiveness; Also have and a kind ofly be shaped on the conical surface in the inboard of bung exactly; Relevant position at bung is equipped with sealing ring, adopts the conical surface seal of sealing ring and bung, but for the plastics staving of blowing; The plastics staving of reservoir pressure in the bucket particularly; Often after the pressurization, the slight deformation of bung, expansion make seal failure.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming that prior art exists, even provide the big more sealing effectiveness of a kind of bung compressive deformation good more, and the locking of bung, outward winding all easily, a kind of sprayer staving in labour-saving and bung sealing device.
The technical scheme of a kind of sprayer staving of the present invention and bung sealing device is: comprise staving and bung; In bung, be shaped on connecting ring, connecting ring is shaped on internal thread, and internal thread is connected with the external screw thread of staving oral area; It is characterized in that said staving oral area outer wall is shaped on scrobicular ring; O shape circle is installed in the scrobicular ring, is shaped on the inclined-plane at the connecting ring inwall of bung, the inclined-plane encloses with O shape and contacts.
The invention discloses a kind of sprayer staving and bung sealing device,, O shape circle is installed in the scrobicular ring through being shaped on scrobicular ring at staving oral area outer wall; Connecting ring inwall at bung is shaped on the inclined-plane, and when bung was rotated down with the staving screwed, the inclined-plane contacted with O shape circle downwards and reaches sealing; When bung is tightened more downwards; Along with dwindling of inclined-plane diameter, more and more tighter to the extruding of O shape circle, O shape circle is flattened slightly; Thereby increased the contact area of O shape circle, reached good sealing effectiveness with the inclined-plane; Simultaneously in bucket when air pressure is arranged,, only can make also that the O shape circle in the bung outside is better to contact with sealing surface bung even the bung distortion is outwards expanded.When uncapping, bung rotates up, and makes O shape circle slowly reply former state, and O shape circle reduces with the contact area on inclined-plane gradually, and it is light, laborsaving to uncap.
Description of drawings
Fig. 1 is the structural representation of a kind of sprayer staving of the present invention and bung sealing device;
Fig. 2 is the local enlarged diagram in A place of Fig. 1.
The specific embodiment
The present invention relates to a kind of sprayer staving and bung sealing device,, comprise staving 1 and bung 2 like Fig. 1-shown in Figure 2; In bung, be shaped on connecting ring 21, connecting ring is shaped on internal thread, and internal thread is connected with the external screw thread of staving 1 oral area; It is characterized in that said staving 1 oral area outer wall is shaped on scrobicular ring 11; O shape circle 5 is installed in the scrobicular ring, is shaped on inclined-plane 22 at connecting ring 21 inwalls of bung 2, the inclined-plane encloses with O shape and contacts.Through being shaped on scrobicular ring 11 at staving 1 oral area outer wall, O shape circle 5 is installed in the scrobicular ring, be shaped on inclined-plane 22 at connecting ring 21 inwalls of bung 2; When bung 2 was rotated down with staving 1 screwed, inclined-plane 22 contacted with O shape circle 5 downwards and reaches sealing, when bung is tightened more downwards; Along with dwindling of inclined-plane diameter, more and more tighter to the extruding of O shape circle, O shape circle 5 is flattened slightly; Thereby increased the contact area of O shape circle, reached good sealing effectiveness with the inclined-plane; When in the bucket air pressure being arranged,, also only can make the O shape circle 5 better sealing surfaces in the bung outside contact simultaneously with bung 2 even the bung distortion is outwards expanded.When uncapping, bung 2 rotates up, and makes O shape circle 5 slowly reply former state, and O shape circle reduces with the contact area on inclined-plane 22 gradually, and it is light, laborsaving to uncap.
