Abstract
The utility model discloses a solid -state waterproof seal structure of safety light curtain end cover, including light curtain main part and end cover, its characterized in that: the last cover of lock screw has respectively, and interference fit is in in the first mounting hole with the second mounting hole in the sealing ring, the sealing ring by the sealing ring upper portion that is loudspeaker forms with be cylindric sealing ring lower part and constitute, sealing ring upper portion extrusion deformation be in between second mounting hole and the lock screw head, the sealing ring lower part extrusion deformation be in between the first mounting hole and the lock screw body of rod, lock screw with sealing ring interference fit. When lock screw attack, deformation was given birth to in the environment -development of lock screw head crush seal, and sealing ring upper portion warp and becomes flat form laminating lock screw head. Adopt this kind of structure can solve the waterproof sealing problem of end cover screw department, and easily disassemble the change.
Description
Technical field
The utility model relates to the solid-state hermetic water-proof structure of a kind of safe light curtain end cap, relates in particular to a kind of good water-proof effect, the solid-state hermetic water-proof structure of safe light curtain end cap easy to use.
Background technology
Safe light curtain product needed reaches IP67, the waterproof requirements such as IP69K, and the sealing at end cap screw hole place is key position. Existing technique adopts the sealing technology such as sealing ring, screw thread glue more, exists in process of production sealing effectiveness poor, complex process, and inconvenience is disassembled, and cannot reach the drawbacks such as IP67 classification of waterproof. 1) adopt sealing ring mode, when screw is in the time shooting end cap, because screw-down torque is difficult to control, cause the excessive deformation of sealing ring, occur that sealing ring turns up, local damage, is out of shape inhomogeneously etc., causes seal failure. 2) adopt screw thread glue mode, when screw is in the time shooting end cap, due to rotation, screw thread glue skewness in screwed hole, especially, in the situation that being subject to variations in temperature, is prone to seal failure. And this technique, is unfavorable for doing over again and maintenance. Complex process. 3) gasket seal or the packing ring of employing ordinary construction, the gap between screw and screw hole is difficult to realize sealing, easily occurs seal failure.
Utility model content
Technical problem to be solved in the utility model is to provide the solid-state hermetic water-proof structure of a kind of safe light curtain end cap, has good water-proof effect, feature easy to use.
For solving the problems of the technologies described above, the technical solution of the utility model is: the solid-state hermetic water-proof structure of a kind of safe light curtain end cap, comprise light curtain main body and the end cap being connected by lock screw with described light curtain main body, in described light curtain main body and on described end cap, be respectively arranged with the first installing hole and the second installing hole that pass for described lock screw, described the first installing hole is screwed hole, described the second installing hole is shoulder hole, its innovative point is: on described lock screw, cover has and is interference fitted in respectively described the first installing hole and neutralizes the sealing ring in the second installing hole, described sealing ring is by being trumpet-shaped sealing ring top and cylindrical sealing ring bottom forms, described sealing ring upper compressive is out of shape between described the second installing hole and lock screw head, the bottom crimp of described sealing ring is between described the first installing hole and the lock screw body of rod, described lock screw and described sealing ring interference fit.
Preferably, the section ovalize on described sealing ring top, and on described section the angle between transverse direction and sealing ring central axis at 30-60 degree.
Preferably, on described sealing ring bottom, be provided with and be embedded in the seal convexity in respective threaded groove on described the first installing hole.
Preferably, described sealing ring top and described sealing ring bottom smooth transition.
Preferably, in described the second installing hole, after described lock screw screws, embed and have waterproof stopper.
Preferably, on described waterproof stopper, be provided with the handle for pulling.
The utility model has the advantage of: adopt said structure, in the time that lock screw is shot, the raw deformation of lock screw head crush seal environment-development, sealing ring upper deformation becomes flat-shaped laminating lock screw head, after the deformation of sealing ring bottom, be pressed in the first installing hole, extrusion modling, between the lock screw body of rod and the first installing hole, forms one deck sealed solid layer. Adopt this kind of structure can solve the waterproof sealing problem at end cap screw place, and be easy to disassemble replacing.

Detailed description of the invention
The solid-state hermetic water-proof structure of a kind of safe light curtain end cap 2 of the present utility model, comprise light curtain main body 1 and the end cap 2 being connected by lock screw 3 with light curtain main body 1, in light curtain main body 1 and on end cap 2, be respectively arranged with the first installing hole 4 and the second installing hole 5 that pass for lock screw 3, the first installing hole 4 is screwed hole, and the second installing hole 5 is shoulder hole. On lock screw 3, cover has and is interference fitted in respectively the first installing hole 4 and neutralizes the sealing ring 6 in the second installing hole 5, sealing ring 6 is by being trumpet-shaped sealing ring top 61 and cylindrical sealing ring bottom 62 forms, 61 crimps of sealing ring top are between the second installing hole 5 and lock screw head, 62 crimps of sealing ring bottom between the first installing hole 4 and the lock screw body of rod, lock screw 3 and sealing ring 6 interference fit. Adopt said structure, in the time that lock screw 3 is shot, there is deformation in lock screw 3 head crush seal rings 6, sealing ring top 61 is deformed into flat-shaped laminating lock screw head, after 62 deformation of sealing ring bottom, be pressed in the first installing hole 4, extrusion modling, between the lock screw body of rod and the first installing hole 4, forms one deck sealed solid layer. Adopt this kind of structure can solve the waterproof sealing problem at end cap 2 screw places, and be easy to disassemble replacing.
The section ovalize on above-mentioned sealing ring top 61, and on section the angle between transverse direction and sealing ring 6 central axis at 30-60 degree. Section adopts the design with the above-mentioned angle of sealing ring 6 central axis, while lock screw 3 being tightened make sealing ring top 61 that deformation occur, sealing ring top 61 after distortion can tie up the cavity forming between locking nut head and the second installing hole 5, thereby ensures to greatest extent sealing property.
In order to play to greatest extent the effect of waterproof sealing, on sealing ring bottom 62, be provided with and be embedded in the seal convexity 7 in respective threaded groove on the first installing hole 4, in order to ensure the smooth of junction, sealing ring top 61 and sealing ring bottom 62 smooth transition. In order to prevent that extraneous steam corrosion lock screw 3 heads from playing waterproof action simultaneously, in the second installing hole 5, after lock screw 3 screws, embed and have waterproof stopper 8, for the ease of pulling waterproof stopper 8, on waterproof stopper 8, be provided with the handle 9 for pulling.
Finally it should be noted that, above embodiment is the non-limiting technical scheme in order to technical scheme of the present invention to be described only, those of ordinary skill in the art is to be understood that, those are modified or are equal to replacement technical scheme of the present invention, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present invention.
