An anti-rotation optical fiber clamp is shown in fig. 1 and 2, and specifically comprises a support 1, a stud 2, a compression nut 3 and at least two clamp blocks 4.
On one hand, the bracket 1 is provided with a mounting hole 11 matched with the stud 2 so as to fix the stud 2; on the other hand, the bracket 1 is also used for fixing to other members, such as a wall surface or a metal section bar by bolts, and in this embodiment, a locking screw hole 12 is provided on the bracket 1 and fixed to the wall surface or the metal section bar by a locking screw 5, such as a hand screw.
In this embodiment, at least two clamping blocks 4 are provided, and each clamping block 4 is provided with a through hole 5 so that the clamping blocks 4 can be sleeved on the stud 2 in a stacked manner. Threading grooves 6 are formed in the lamination surface (the surface through which the stud 2 passes) of the clamping blocks 4, so that the threading grooves 6 of two adjacent clamping blocks 4 form a wire clamping hole 7 for fixing the optical fiber cable after being butted. It will be understood that the threading grooves 6 and in particular the thread trapping holes 7 formed after butt-joint are all parallel to each other.
And the compression nut 3 is screwed on the stud 2, so that the processing clamping block 4 is clamped and fixed between the bracket 1 and the compression nut 3.
In this embodiment, be provided with protruding stupefied 10 on the surface that support 1 and clamp splice 4 contacted, this stupefied 10 shape and size all with the threading recess 6 looks adaptation on the clamp splice 4, so set up for clamp splice 4 is compressing tightly the back on support 1 by gland nut 3, and clamp splice 4 can't rotate around double-screw bolt 2, thereby can avoid gland nut 3 to take place not hard up the condition and appear, can effectually maintain the normal use of fastener.
It can be understood that, in order to increase the number of the optical fiber cables that can be fixed, threading grooves 6 are provided on two opposite stacking surfaces of the clamping blocks 4, so that a threading hole 7 for fixing the optical fiber cable can be formed between any two adjacent clamping blocks 4, and when the threading grooves 6 provided on the two opposite stacking surfaces of the clamping blocks 4 are the same (the diameter size is the same), the cable clamp of the present invention can be used for fixing the optical fiber cables with the same diameter, wherein, the threading groove 6 can be more than one so as to fix more optical fiber cables; or,
