Abstract

The utility model relates to a cable clip used for matching oil well underground cables. In the utility model, an outer body of the cable clip is a circular butted ring-shaped body of which the inner layer is an elastic metal body of which the outer layer is rubber protecting layer; the inner periphery of the ring-shaped body is provided with a cambered groove and a semicircular groove which match cables; a locking mechanism is positioned on the commissure of the outer body of the cable clip. The cable clip adopting the scheme can resist radial pressure and simultaneously increase bonding force with cables by the rubber layer on the outer layer, can effectively prevent the abrasion and the upper and lower movement of cables and has the advantages of simple structure, convenient operation and repeatable use.

Description

Plug-in type electromagnetic cable protection clamp

One, technical field: the utility model relates to a kind of strain relief clamp that is used with the oil well downhole cable.

Two, background technology: oil well is in production operation, and the down-hole need be provided with various cables such as service cable, communication cable or the like.The mode that adopts is to utilize steel band or cable protection piece that cable is fixed on oil pipe or other instruments at present.Though steel band is simple, easily cable is caused damage; The cable protection piece is cable to be fixed by bolt locking by two clamps, its complex structure, and it is big to take up room, poor practicability.

Three, summary of the invention: the purpose of this utility model is exactly at the problems referred to above, provides a kind of practicality good cable protection clamp.Its technical scheme is: the clamp ectosome is the ring bodies of a circular butt joint, its internal layer is the rubber-like metallic object, skin is the rubber sheath, is provided with the deep-slotted chip breaker and the semi-circular groove that cooperate with cable on the inner rim of ring bodies, and locking mechanism is positioned at the joint of clamp ectosome.Locking mechanism comprises that clamp locking chamber and clamp insert tongue, clamp locking chamber is positioned at an end face of clamp ectosome joint, and there is an arc-shaped slot centre, is provided with the gingival cyst of mucous gland in the newborn tooth on the face of slotted eye, in the outdoor open hole of radially offering of clamp locking, insertion instrument and the effect of gingival cyst of mucous gland in the newborn tooth in the open hole; Clamp inserts tongue and is connected on another end face, and ledge is processed with serrated slot, behind the slotted eye of insertion clamp locking chamber, with the mutual interlock of the teeth on the slotted eye.

Adopt the strain relief clamp of such scheme to have: the outer field rubber layer of clamp can resist the pressure from radially, increase simultaneously and cable between adhesion, can effectively prevent the wearing and tearing of cable and play up and down; Simple in structure, easy to operate, can reuse.

Four, description of drawings:

Fig. 1 is a deployed condition structure chart of the present utility model;

Fig. 2 is a lock-out state structure chart of the present utility model.

Five, embodiment:

With reference to attached Fig. 1 and 2, clamp ectosome 1 is the ring bodies of a circular butt joint, and its internal layer is the rubber-like metallic object, and skin is the rubber sheath.On the inner rim of ring bodies, be provided with the deep-slotted chip breaker 3, elastic groove 7 and the semi-circular groove 4 that cooperate with cable.Locking mechanism is positioned at the joint of clamp ectosome, comprises that clamp locking chamber 5 and clamp insert tongue 6.Clamp locking chamber 5 is positioned at an end face of clamp ectosome joint, and there is an arc-shaped slot centre, is provided with the gingival cyst of mucous gland in the newborn tooth on the face of slotted eye.Clamp inserts tongue 6 and is connected on another end face, and ledge is processed with serrated slot, and the gingival cyst of mucous gland in the newborn teeth size of the size of serrated slot and clamp locking chamber 5 is suitable.After clamp inserts the slotted eye of tongue insertion clamp locking chambers 56, with the mutual interlock of the teeth on the slotted eye.In the outdoor open hole 2 of radially offering of clamp locking, insertion instrument and the effect of gingival cyst of mucous gland in the newborn tooth in the open hole 2.

During use, after clamp inserted tongue 6 and insert clamps locking chambers 5, utilize the tight clamp ectosome 1 of clamp clamp, make clamp insert the gingival cyst of mucous gland in the newborn tooth locking of tongue 6 and clamp locking chamber 5.When unlocking, insert open hole 2 with pin, shrink in the gingival cyst of mucous gland in the newborn teeth directional of extruding clamp locking chamber 5, the serrated slot that gingival cyst of mucous gland in the newborn tooth and clamp insert tongue 6 breaks away from, and unlocks.
