Abstract
The utility model relates to a casting type cable protector. The casting type cable protector comprises a snap body and a snap ring. The snap body and the snap ring are hinged together through a hinge pin at one side. The other side of the snap body is installed with a spindle, and the spindle is connected with a bolt which intersects with the spindle vertically. The other side of the snap ring is provided with a step groove which is matched with the bolt. The casting type cable protector is characterized in that the shoulder surface of the step groove is provided with a limit raised portion near the outer edge position, and the inner circular surface of the snap ring is provided with a slippage prevention type rasied portion. The limit raised portion which is arranged on the shoulder surface of the snap ring can be used to avoid the bolt from slipping out of the outer edge portion of the step groove in the installation process of the snap body and the snap ring, so advantages of easy installation, shortened installation time and improved installation efficiency are realized; and the slippage prevention type raised portion which is arranged on the inner circular surface of the snap ring can be used to increase the friction force between the cable protector and an oil pipe, improve the firmness of the connection of the cable protector and the oil pipe, and avoid the up and down endplay of the cable protector in the descending or raising process due to the collision with the sleeve.
Description
Technical field
The utility model relates on the oil well oil pipe and to be used for protective device fixing and the protection pipeline, particularly a kind ofly is convenient to install, install firmly cast moulding electric cable protector.
Background technology
Electric cable protector be a kind of be installed on the oil pipe or the position such as adjacent oil distributing pipe box cupling be used for protective device fixing and protection cable and data wire.At present, common electric cable protector is the cast moulding electric cable protector, and it is made of card, one or two snap ring, and the inner ring of card is provided with wire casing.Card and snap ring docking form closing structure.The card opposite side is equipped with rotating shaft, is connected with perpendicular crossing bolt in the described rotating shaft, and the opposite side of snap ring is provided with the step trough that matches with bolt.Concrete, when card and snap ring were in closed and locked state, bolt passed step trough, and the head of bolt is pressed on the circular bead surface of step trough.Card and snap ring adopt above-mentioned syndeton, when Fast Installation, the problem that bolt skids off from the step trough outer rim position of snap ring can occur, thereby reduce installation effectiveness.In addition; above-mentioned electric cable protector go into the well or in the well process; the phenomenon that electric cable protector collides internal surface of sleeve pipe can appear; this collision has reduced the firmness that electric cable protector is connected with oil pipe; large or collide more frequently in the situation at impulsive contact force, the phenomenon that electric cable protector jumps up and down along oil pipe can appear.
Summary of the invention
The utility model provides a kind of cast moulding electric cable protector for solving the technical problem that exists in the known technology, and this electric cable protector has made things convenient on the one hand installation, reduced the set-up time and improved installation effectiveness; Improve on the other hand the firmness that is connected with oil pipe, avoided it to jump up and down along oil pipe.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of cast moulding electric cable protector, comprise card and snap ring, described card and snap ring are hinged by bearing pin in a side, the card opposite side is equipped with rotating shaft, be connected with perpendicular crossing bolt in the described rotating shaft, the opposite side of snap ring is provided with the step trough that matches with bolt, it is characterized in that: be provided with spacing preiection near outer peripheral position on the circular bead surface of described step trough; The inner headed face of described snap ring is provided with anti-skidding projection.
The technical scheme that the utility model can also be taked is:
Described spacing preiection is the semi-cylindrical projection.
Described anti-skidding projection is equally distributed round point shape projection.
Advantage and the good effect that the utlity model has are:
The above-mentioned spacing preiection that is arranged on the snap ring circular bead surface has avoided card and snap ring when Fast Installation, and bolt skids off from the outer rim position of step trough, thereby has made things convenient for installation, reduced the set-up time and improved installation effectiveness; The above-mentioned anti-skidding projection that is arranged on the snap ring inner surface has increased the frictional force of electric cable protector and oil pipe, has improved the firmness that electric cable protector is connected with oil pipe, has avoided electric cable protector going into the well or carrying in the well process because colliding sleeve pipe and jumping up and down.
Description of drawings
Fig. 1 is structural representation Fig. 1 of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is structural representation Fig. 2 of the present utility model.
Among the figure: 1, card; 2, snap ring; 2-1, step trough; 2-2, spacing preiection; 2-3, anti-skidding projection; 3, bolt; 4, rotating shaft.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1-3, a kind of cast moulding electric cable protector comprises card 1 and snap ring 2, and described card and snap ring are hinged by bearing pin in a side.The card opposite side is equipped with rotating shaft 4, is connected with perpendicular crossing bolt 3 in the described rotating shaft, and the opposite side of snap ring is provided with the step trough 2-1 that matches with bolt.Be equipped with spacing preiection 2-2 near outer peripheral position on the circular bead surface of described step trough, the inner headed face of described snap ring is provided with anti-skidding protruding 2-3.
In the technique scheme; Described spacing preiection further adopts the semi-cylindrical projection.Described anti-skidding projection further adopts equally distributed round point shape projection.
The above only is the better example of executing of the present utility model, is not to limit practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all fall into technical scope of the present utility model.
