Abstract
The utility model discloses a connector box sealing ring limiting sleeve, which belongs to the technical field of cable joint box sealing. In order to adapt to the requirement for improving the sealing effect in assembly of a screw-extrusion joint box cable fast-sealing component, the connector box sealing ring limiting sleeve is formed by butt jointing of a limiting casing and a sealing ring casing, the cavity of the limiting casing is provided with internal threads near the port of one end, a limiting part is arranged on one side of the internal threads, the inner side of the cross section of the limiting part is a polygon, the side wall of the other end of the limiting casing is provided with bayonets, one end of the sealing ring casing is inserted into the open end of the limiting sleeve, the outer circular surface of the sealing ring casing is provided with bulges corresponding to the bayonets, and a step shoulder is arranged in the sealing ring casing. According to the utility model, the sealing effect of cable joint boxes is effectively improved, and sealing ring rotation and deformation in sealing component assembly is avoided.
Description
Technical field
The utility model belongs to cable joint box technical field of sealing technology, especially relevant with a kind of connector box O-ring seal stop collar.
Background technology
Existing cable splice closure is generally provided with many optical cable inlet/outlet pipes on box body, the sealing of optical cable inlet/outlet pipe can adopt mechanical seal mode to seal conventionally, conventional mechanical seal mode is extrusion mechanical sealing at present, being about to block is set on optical cable inlet/outlet pipe, between block and optical cable inlet/outlet pipe, be provided with O-ring seal, cable is through the through hole of O-ring seal, block is rotated and is threaded with optical cable inlet/outlet pipe, block plays squeezing action to O-ring seal, O-ring seal is realized and be radially expanded realization sealing, but the spread configuration of many optical cable inlet/outlet pipe comparatively denses is on a wherein side of cable splice closure box body, it is not very convenient installing, during operation, easily the optical cable to side exerts an influence, and block easily make when being threaded between optical cable inlet/outlet pipe screws tight O-ring seal in company with together with rotational deformation, it is not fine making sealing effectiveness.For this reason, the inventor has developed a kind of good sealing effect, has operated again the connector box cable fast sealing assembly of convenient and spiral squeezing type, for adapting to the needs of sealing assembly and guaranteeing sealing effectiveness and avoid O-ring seal rotational deformation when assembling, design connector box O-ring seal stop collar O-ring seal has been played to position-limiting action when assembling, prevented O-ring seal rotational deformation.
Utility model content
The purpose of this utility model is exactly to adapt to spiral squeezing type mechanically-sealing apparatus can improve sealing effectiveness and easy to operate needs when assembling, and a kind of easy to operate, connector box O-ring seal stop collar of effectively improving sealing effectiveness is provided.
For this reason, the utility model is by the following technical solutions: connector box O-ring seal stop collar, it is characterized in that, described stop collar is formed by limit casing and the docking of O-ring seal sleeve pipe, limit casing inner chamber is provided with internal thread near port, one end, internal thread one side is provided with limiting section, the inner side, transversal section of limiting section is polygon, the sidewall of the described limit casing other end is provided with bayonet socket, described O-ring seal sleeve pipe one end is plugged in described stop collar opening one end, on the periphery of O-ring seal sleeve pipe, be provided with the projection corresponding with described bayonet socket, in described O-ring seal sleeve pipe, be provided with step shoulder.
As to technique scheme supplement and perfect, the utility model also comprises technical characterictic.
The inner side, transversal section of described limiting section is hexagon.
Described bayonet socket is evenly provided with 4 along the circumferencial direction of described limit casing, on the periphery of described O-ring seal sleeve pipe, be provided with the quantity corresponding with described bayonet socket and position, when limit casing and O-ring seal sleeve pipe docking assembling, each bayonet socket and projection cooperatively interact and clamp, and realize between the two radially spacing of limit casing and O-ring seal sleeve pipe.
Use the utility model can reach following beneficial effect: by polygonal limiting section is set in limit casing, when being coordinated with O-ring seal and assembly thereof, plays stop collar position-limiting action, avoid connector box cable fast sealing assembly to make O-ring seal rotate distortion when screw extrusion is assembled, affect sealing effectiveness.
