Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides a technical solution of a multi-cable fixing clip:

the utility model provides a many cable fixing clamp, includes U-shaped hook 1, the one end of U-shaped hook 1 is connected with double-screw bolt 2, the cover is equipped with fixed fork 3, fixed fork set nut 4, sleeve nut 5, sleeve pipe 6 and expansion nut 7 on the double-screw bolt 2 in proper order. In order to prevent the fasteners from loosening, a fixing fork gasket 11 is arranged between the fixing fork 3 and the fixing fork positioning nut 4, and a spring washer 12 and a flat washer 13 are sequentially arranged between the sleeve nut 5 and the sleeve 6. The fixed fork 3 comprises a ring bottom 8 and two triangular abutting pieces 9, wherein the respective vertex angles of the two triangular abutting pieces 9 are fixedly connected with the ring bottom 8, and the two triangular abutting pieces 9 are parallel to each other. Meanwhile, the heights of the tops of the two triangular abutting pieces 9 are the same, so that the fixed cable is perpendicular to the plane of the U-shaped hook 1 and is in a good fixed state. In order to stabilize the parallel relationship of the two triangular abutment pieces 9, a connecting piece 10 is provided between the two triangular abutment pieces 9 at the opening side of the U-shaped hook 1, so as to prevent the two triangular abutment pieces 9 from being forked due to high-strength extrusion. The top height of connecting piece 10 is greater than the top height of triangle butt joint piece 9, makes to form a slot between the opening of U-shaped hook 1 and connecting piece 10, carries out horizontal spacing to fixing the cable in U-shaped hook 1, prevents that the cable from the opening part roll-off of U-shaped hook 1. The inner diameter of the ring bottom 8 is 2mm larger than the diameter of the section of the U-shaped hook 1, the positioning nut 4 of the fixing fork is adjusted to a proper position, and the fixing fork 3 can move in the plane of the U-shaped hook 1 in a small range. When no cable is placed in the U-shaped hook 1, the narrow opening between the opening of the U-shaped hook 1 and the connecting piece 10 can be opened to the maximum, so that the cable can be conveniently placed in the narrow opening, and the narrow opening is gradually reduced as the number of the cables is increased; when putting into last cable, the slot reduces to minimum, carries out tentatively spacing to the cable of placing in the U-shaped hook, and the fixed fork set nut 4 of screwing at last firmly fixes the cable. The fixed fork positioning nut 4 is divided into a hexagon nut and an external thread bolt, the external thread bolt is in limit sleeve fit with the hexagon nut, anti-skid lines are arranged on the surface of the external thread bolt, and the external thread bolt can be directly adjusted by hands.

The utility model discloses a theory of operation and use flow: a drill hole with proper depth is drilled on the surface of a wall where the wire clamp needs to be installed, the wire clamp is inserted into the drill hole, the sleeve nut 5 is rotated towards the wall side, the sleeve 6 moves towards the expansion nut 7 under the pushing of the sleeve nut 5, the expansion nut 7 expands the sleeve 6, and finally the wire clamp is fixed in the drill hole. The fixing fork positioning nut 4 is adjusted to a proper position, and the fixing fork 3 can swing back and forth in a small range in the plane of the U-shaped hook 1. When the cable is not placed in, the narrow opening formed by the U-shaped hook 1 and the connecting piece 10 is opened to the maximum, the narrow opening is gradually reduced along with the gradual placement of the cable, the last cable is placed in, the narrow opening just can pass through one cable, and the cable clamp achieves preliminary limiting on the cable at the moment. And finally, screwing the fixing fork positioning nut 4 to enable the fixing fork 3 and the U-shaped hook 1 to clamp the cable. At the moment, the width of the narrow opening is smaller than the diameter of the cable, and the cable cannot slide out of the narrow opening.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
