Abstract

The utility model discloses a direct-turning wire bending key. Planes of two earring-shaped objects are arranged at the top end of the direct-turning wire bending key from left to right and are correspondingly and linearly unfolded. The upper hole of a circular tubular body is arranged at the lower end of the direct-turning wire bending key and is connected with the lower end of the planes. A convex body is arranged on the external edge of the lower hole of the circular tubular body and extends properly after the convex body is bent outward for a proper angle and is bent downward for a proper angle. Holes penetrating through each other are arranged on the middle planes of the two earring-shaped objects. A straight line formed by connecting the central points of the two holes is perpendicularly intersected with a straight line formed by connecting the central points of the upper hole and the lower hole of the tubular body. The utility model has the advantages that: 1. a conducting wire can be directly coiled and is sheathed on the external surface to ensure that the conducting wire does not get loose and no spark is apt to occur; 2. when in use, the conducting current is large, the conducting resistance is small and the good conductivity can lead to the abandonment of copper connectors; and 3. the structure is simple, the operation is convenient, the performance is stable, the production cost is low and the use effect is good.

Description

Directly revolve the turning guide marking key

Technical field;

This reality is with new type Shibuya and a kind of electric wire connection method, a kind of turning guide marking key that directly revolves.

Background technology;

Present employed electric wire connection method mainly is exactly following several; 1, square pressing plate, 2, plain washer, 3 jack types, 4 bushing types, 5, u shaped connector, 6, welded type.

First three class methods in this type of technology are in use more convenient, are usually used in the low voltage electrical equipment, and the 6th kind of method also often adopts in low voltage electrical equipment, the 5th kind of method often is used in the supply line, more loaded down with trivial details during operation, but result of use is good, is difficult for loosening.Though convenient and time-saving laborsaving during other method wiring, in use owing to expand with heat and contract with cold and factor such as oxidation, the junction is loosening easily, obscission occurs sparkling.Though occur a patent No. in recent years again and be 2008200597807 utility model technology, also exist some not places of person of modern times's meaning in use.

The utility model content

Goal of the invention;

Goal of the invention of the present utility model is exactly in order to overcome above-mentioned defective.

Beneficial effect;

1, make lead be surrounded snare outside bolt reliably, be difficult for loose or dislocation, be difficult for sparkling.

2, conductive current is big during use, and conductive resistance is little, and its excellent conductive capability is enough to abandon copper joint, thereby is saved the copper resource in a large number.

3, the utility model is simple in structure, and dependable performance is easy to use, and production cost is low.

Technical scheme;

The expansion that is in line of two earrings shape object plane correspondences is arranged from left to right directly revolving turning guide marking key top, its lower end has the last aperture of a round tubular body to be connected with its lower end, plane, there is a bossy body outwards to do to do again after the turning of suitable angle to remake suitable extension after the turning of suitable angle under the round tubular body on the outer edge of aperture downwards, porose to wearing on two earrings shape object mid-planes, the straight line that the aperture central point is linked to be about straight line that two central point of hole are linked to be and the tubular body is done right-angle crossing.

 

Porose at the plane of binding post plate proximal portion to wearing, screw thread is arranged in the hole, plain washer on the aperture, spring washer is arranged on the plain washer, three central point of hole coincide up and down, have bolt to seal in from top to bottom in three holes, be screwed in the threaded hole at plane, nearly top place of binding post plate, the lower end mouth of pipe that straight line revolves the turning guide marking key then is enclosed on the bolt head.

The present invention will be described below in conjunction with Figure of description Fig. 1 to Fig. 5

Embodiment

1, concrete type shape structure

The expansion that is in line of two earrings shape object plane correspondences is arranged from left to right directly revolving turning guide marking key top, its lower end has the last aperture of a round tubular body to be connected with its lower end, plane, there is a bossy body outwards to do to do again after the turning of suitable angle to remake suitable extension after the turning of suitable angle under the round tubular body on the outer edge of aperture downwards, porose to wearing on two earrings shape object mid-planes, the straight line that the aperture central point is linked to be about straight line that two central point of hole are linked to be and the tubular body is done right-angle crossing.

2, concrete assembling mode;

On the plane, nearly top of long strip type post plate 5 outside the screwed aperture, put plain washer 4 earlier, put spring washer 3 then, again from top to bottom at two packing rings 3, after sealing in the aperture of bolt 6 to the rectangular post plate 5 nearly planes, top in 4 the hole, screw in this hole, after this aperture, lower end of directly revolving turning guide marking key 1 is enclosed within on the top of bolt 6 again, assembling so far finishes.

The specific implementation effect;

During use the bare wire head is inserted under bossy body 2 inside corners place bolts 6 plain washer outward that directly revolves turning guide marking key 1 lower end, after outside the aperture on the long strip type post 5 on the plane, do rotation counterclockwise directly revolving turning guide marking key 1, make the bare wire head be curved corral behind bolt 6 outsides, take off and directly revolve the turning guide marking key, screw bolt 6 and get final product.

Claims (1)

1. one kind directly revolves the turning guide marking key and it is characterized in that: its top has the expansion that is in line of two earrings shape object plane correspondences from left to right, its lower end has the last aperture of a round tubular articles to be connected with its lower end, plane, there is a bossy body outwards to do to do again after suitable angle is extended suitably to extend after suitable angle is turned under the round tubular body on the outer edge of aperture downwards, porose on the two earrings shape object mid-planes, the aperture central point was done right-angle crossing about two central point of hole were linked to be straight line and tubular body.
