Description
[technical field]
The utility model relates to a kind of sealing-locking device, relates in particular to the sealing-locking device of connection cable in a kind of communication equipment and other Electric Appliance Cabinet.
[background technology]
In existing technology, cable passes through communication equipment and the easier method of the general employing of other Electric Appliance Cabinet, for example, after cable passes cabinet or rack, cable is beaten a knot in case pull out; Or on cabinet or rack, be packed with an elastic ring that internal diameter is less, only depend on the elastic force of elastic ring inboard that cable is fixed; Or fixation clip is set on cabinet or rack fixes the cable that enters in cabinet or the rack.Above-mentioned method can play the effect of fixed cable substantially, but all has easily frayed or twisting and breaking of cable; Communication equipment and other Electric Appliance Cabinet poor sealing performance; The aperture that cable passes through cabinet or rack such as can not change flexibly at defective.
Existing a kind of sealing-locking device can be consulted Chinese patent No. 98803819.6, this denomination of invention is an angle of 90 degrees sealing nut, this disclosure of the Invention the close accessory of a kind of liquid, it can be installed on the housing of an electric or mechanical device, comprise one near the one end and from the housing outwardly directed grip portion.More particularly, accessory can comprise sealing nut, and sealing nut comprises a base; Base has one and extends and its size and dimension makes its passage of the grip portion of receiving connector separably along this base longitudinal axis.Sealing nut also comprises a lid, it is rotatably connected on the base, thereby make this lid can be between enable possition and off-position movable, when the enable possition, lid fully exposes the passage of base, so that cable is with the cardinal principle linear state and roughly pass sealing nut abreast with the longitudinal axis of base; When off-position, the passage in the lid covering base, pilot cable is crooked within it loosely to make lid.A maintaining body is set, so that lid is maintained in its closed position.The pawl of a gland of a plurality of encirclements is set on grip portion, thereby firmly grasps the adjacent part of cable with the close and release types of liquid.Yet above-mentioned an angle of 90 degrees sealing nut complex structure.
[summary of the invention]
It is a kind of simple in structure that the purpose of this utility model is to provide, reliable waterproof, and long service life, and can change the sealing-locking device that cable passes through the aperture within the specific limits.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of sealing-locking device is provided, it comprises the tie down screw that is hollow cylindrical, the two ends outer surface of this tie down screw all is provided with external screw thread, one end external screw thread of this tie down screw is provided with nut and sealing ring, the other end external screw thread of this tie down screw is provided with the locking swivel nut, an end that is provided with the locking swivel nut of this tie down screw is provided with the strip elastic card claw that a circle is connected with the end, this strip elastic card claw is built-in with conduit, two faces between adjacent of this strip elastic card claw are one to favour the inclined-plane of this tie down screw circular arc tangential line, respectively the end of this strip elastic card claw is provided with aduncate hook-like, and inboard one end of this locking swivel nut is provided with outwards gradually little smooth surface of internal diameter.
The beneficial effects of the utility model are, sealing-locking device of the present utility model is coupled owing to be provided with a locking swivel nut on an end external screw thread of tie down screw tool strip elastic card claw, inboard one end of locking swivel nut is provided with outwards gradually little smooth surface of internal diameter, therefore when tightening the locking swivel nut, strip elastic card claw one end be subjected to close in the restriction gradually of curved surface be subjected to tight, the internal diameter that is the sealing locking device diminishes gradually, force conduit to compress cable, thereby make and be in good sealing state between sealing locking device and cable, therefore sealing-locking device of the present utility model is simple in structure, reliable waterproof, long service life, and can change cable within the specific limits and pass through the aperture.
