Background

At present, the protection heads are arranged on electrical equipment such as a plug and a line card (the line card has the function of erecting a cable on a wall surface), the purpose of arranging the protection heads is mainly to protect the cable, the material of the protection heads is generally that shown in figure 1, a protection head is connected to a cable connection part of the plug, four rows of grooves (101) are formed in a cylinder body (102), the shape of the grooves (101) is in a 90-degree fan shape, the cylinder body (102) is generally made of bulletproof rubber or jade powder or ampere base plastic powder, the four rows of grooves (101) are in a linear arrangement, the distances between the four rows of grooves (101) are equal, and as each groove (101) is in a 90-degree fan shape and the distances between the four rows of grooves (101) are equal, when the protection heads are required to be folded, the groove wall of each groove (101) cannot be folded, but the protection heads are not provided with the flexibility when the plug and the line card are required to be used in many occasions.

Disclosure of Invention

The invention provides a flexible swivel, a flexible line card and a flexible plug aiming at the problems.

The technical scheme adopted by the invention is as follows:

the utility model provides a flexible swivel, includes the barrel, four rows of recesses have been seted up on the barrel, its characterized in that, the recess is lack the disk type, and one side edge of recess is the linear type, and the opposite side edge of recess is the linear type, and adjacent two rows of recesses interval staggered arrangement together each other.

Because the edge of one side of the groove on the barrel is linear, the edge of the other side of the groove is linear, and the two adjacent rows of grooves are alternately arranged together at intervals, when the barrel needs to be bent, the groove walls on the two sides of the groove can be mutually closed (or far away), and because the groove walls on the two sides of the groove can be mutually closed or far away, the barrel can be smoothly bent, and when the cable is clamped in the barrel, the cable can be smoothly bent.

The groove with the groove walls being close or far away is formed in the barrel, so that the barrel is bendable, and when the barrel is fixed to the line clip or the plug, the cable clamped in the barrel can be bent smoothly.

Optionally, the cylinder is a truncated cone type cylinder.

Optionally, each row of grooves has at least four grooves, and the number of grooves in each row of grooves is equal.

The flexible line card comprises a card body, wherein a clamping groove is formed in the card body and is used for being matched with the wall surface in a clamping manner, and the flexible line card further comprises a flexible rotating head.

Optionally, the card body is internally provided with a through hole, the through hole is the same as a round hole in the cylinder body, and the through hole and the round hole are both cable channels.

Optionally, the card body is the quadrangle card body, the draw-in groove is sharp draw-in groove, and the draw-in groove has a plurality ofly, and the draw-in groove distributes in the four sides of card body.

Optionally, the spring hole is seted up on the both sides cell wall of draw-in groove still includes the kicking block, the kicking block passes through spring movable mounting in the spring hole, the kicking block is used for the tight wall in top.

It should be noted that the present line clip is used for erecting a cable to a wall surface (such as a wall surface of a wall and a wall surface of a three-in-one plate), so that the clamping groove of the clamping body is used for being matched with the wall surface, and when the clamping groove is clamped with the wall surface, the top block on the wall of the clamping groove is tightly propped against the wall surface, so that the matching between the wall surface and the clamping groove is firmer.

The flexible plug comprises a plug end, a flexible rotating head and a connecting rod, wherein the plug end is used for being connected with a socket, and the flexible rotating head is fixedly matched with the plug end.

The plug-in terminal may be a three-phase (electrical) plug-in terminal or a two-phase (electrical) plug-in terminal.

The beneficial effects of the invention are as follows: through set up the recess that the cell wall can draw close or keep away from on the barrel for the barrel has had the bendability, and when the barrel was fixed to ply-yarn drill or plug, the cable of clamp dress in the barrel can buckle smoothly.
