Abstract
The utility model discloses a sealing structure of an exterior lampshade. The sealing structure of the exterior lampshade comprises an ornamental ring and a bolt. The bolt is sheathed with a sealing gasket; the ornamental ring is provided with a bolt hole for connecting the bolt; the upper part of the bolt hole is provided with a closed hole for embedding the sealing gasket; and the joint of the bolt hole and the closed hole is provided with an extrusion hole used for extruding the sealing gasket. According to the sealing structure of the exterior lampshade disclosed by the utility model, the sealing effect of the sealing gasket is enhanced, and sealing is more reliable.
Description
Technical field
The utility model relates to a kind of outer dress lampshade hermetically-sealed construction, belongs to sealing mounting technology field.
Background technology
At present, screw is externally adorned the sealing that need guarantee screw hole when lampshade carries out fastening installation, anti-sealing enters the situation that causes short circuit in the light fixture and burn out lamp, the sealing of the outer dress lampshade under the prior art adopts the sealing of O RunddichtringO to install more, but adopts the sealing of O RunddichtringO to have the insecure problem of sealing.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, provides a kind of reliable sealing to adorn the lampshade hermetically-sealed construction outward.
The technical scheme that realizes the utility model purpose is: a kind of outer dress lampshade hermetically-sealed construction, it comprises case ring and screw, be set with sealing gasket on the screw, have the screw hole of attachment screw on the case ring, be provided with the closed hole of setting-in sealing gasket on the top of screw hole, be provided with the extruded hole of crush seal pad in the junction of screw hole and closed hole.
Further, be set with plain cushion on the described screw, this plain cushion is between the head of screw of sealing gasket and screw.
Further, described extruded hole is up big and down small taper hole.
After having adopted technique scheme, up big and down small taper hole is the crush seal pad in the downward precession of screw, makes sealing gasket be subjected to inside pressure, thereby is close to screw, has strengthened the sealing effectiveness of sealing gasket, seals more reliable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Content of the present utility model is easier to be expressly understood in order to make, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below,
As shown in Figure 1, a kind of outer dress lampshade hermetically-sealed construction, it comprises case ring 1 and screw 2, be set with sealing gasket 3 on the screw 2, have the screw hole 1-1 of attachment screw 2 on the case ring 1, be provided with the closed hole 1-2 of setting-in sealing gasket 3 on the top of screw hole 1-1, be provided with the extruded hole 1-3 of crush seal pad 3 in the junction of screw hole 1-1 and closed hole 1-2.Be set with plain cushion 4 on the screw 2, this plain cushion 4 is between the head of screw 2-1 of sealing gasket 3 and screw 2.Extruded hole 1-3 is up big and down small taper hole.
Operation principle of the present utility model is as follows:
Up big and down small taper hole is the crush seal pad in the downward precession of screw, makes sealing gasket be subjected to inside pressure, thereby is close to screw, has strengthened the sealing effectiveness of sealing gasket, seals more reliable.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
