Description
Technical Field
The utility model relates to a nut, in particular to half to tooth self-locking nut.
Background
At present, a wiring device (a cabling rack, a grid, a tail fiber groove and the like) installation program of a machine room fixes a screw rod at the top of the machine room, screws a nut on the screw rod, penetrates two ends of a cross arm of the wiring device into the screw rod, locks the cross arm up and down by the nut, and fixes the wiring device by a fastener through the cross arm. Therefore, the capacity expansion of the wiring equipment (a chute, a grid, a tail fiber groove and the like) of the old communication machine room mainly has the following defects:
1. because the wiring equipment (a wiring rack, a grid, a tail fiber groove and the like) of the communication machine room is fixed on the cross arm, and the connection between the cross arm and the screw rod is vertically fastened by nuts. Therefore, to add a layer of wiring equipment to the original wiring equipment, the original whole wiring equipment must be completely removed, then two nuts are screwed on each screw rod, the added layer of cross arm is locked by the two nuts, meanwhile, the wiring equipment of the added layer is fixed on the newly added cross arm, and finally, the removed original wiring equipment is fixed on the screw rod again. Thus, the workload is large and the method can not be implemented basically.
2. Many facilities use a new piece of wiring equipment. But the cost is higher, the workload is large, and the whole machine room is not beautiful.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to the not enough of prior art, provide a half to tooth self-locking nut.
In order to achieve the above object, the present invention takes the following measures:
a half-paired self-locking nut comprises a flange nut body and a groove nut body which are connected with each other, wherein threaded holes with two through surfaces are formed in the flange nut body and the groove nut body;
the outer part of the half-pair-tooth self-locking nut forms a regular hexagon;
the cross section of the flange is in an L-shaped structure, and the groove is in a corresponding L-shaped structure;
the width of the notch is larger than the diameter of the threaded hole;
a gap is reserved between the flange and the groove;
the groove is of an arc-shaped structure concentric with the threaded hole, and two ends of the groove are communicated with the notch;
the depth of the notch is larger than one half of the distance between two opposite side surfaces of the half-pair-tooth self-locking nut.
The utility model has the advantages that: the novel expansion machine has the advantages of practicality, low production cost, novel structure, safety, firmness, convenience in installation, time and labor conservation for the expansion of the machine room, and saving of a large amount of economic cost.

Detailed Description
A half-pair-tooth self-locking nut comprises a flange nut body 1 and a groove nut body 2 which are connected with each other, wherein the flange nut body 1 and the groove nut body 2 are provided with threaded holes 1-2 with two through surfaces, the inner wall of each threaded hole 1-2 is provided with an internal thread, one surface of the flange nut body 1, which is close to the groove nut body 2, is provided with a flange 1-1 for connecting the flange and the groove nut body, one surface of the groove nut body 2, which is close to the flange nut body 1, is provided with a groove 2-1 for connecting the flange and the groove nut body, the flange 1-1 is connected in the groove 2-1 to realize the connection between the flange nut body 1 and the groove nut body 2, the side surfaces of the flange nut body 1 and the groove nut body 2 are both provided with notches 1-3 communicated with the threaded holes 1-2, and the opening directions of the notches 1-3 on the flange nut body 1 and the groove nut body 2 are reversely arranged.
The outer part of the half-pair-tooth self-locking nut forms a regular hexagon.
The cross section of the flange 1-1 is in an L-shaped structure, and the groove 2-1 is in a corresponding L-shaped structure.
The width of the notch 1-3 is larger than the diameter of the threaded hole 1-2.
A gap is reserved between the flange 1-1 and the groove 2-1. So that the two (the flange nut body 1 and the groove nut body 2) can not be separated and can rotate relatively.
When the screw rod is inserted into the utility model, one (such as the flange nut body 1) can be used for fixing the thread surface. The other (such as the groove nut body 2) is fixed by rotating around the central axis.
The groove 2-1 is in a circular arc structure concentric with the threaded hole 1-2, and two ends of the groove 2-1 are communicated with the notch 1-3.
The depth of the notch 1-3 is larger than one half of the distance between two opposite side surfaces of the half-pair-tooth self-locking nut.
The half-pair-tooth self-locking nut in the scheme is mainly used for expanding the capacity of original wiring equipment (a wiring rack, a grid, a tail fiber groove and the like) of an old communication machine room.
When a new wiring product is added, the half-pair-tooth self-locking nut is used, only the position of a gap 1-3 of the side face of the half-pair-tooth self-locking nut is inserted into a lead screw installed on original wiring equipment, the half-pair-tooth self-locking nut is screwed by a spanner, then a cross arm for placing the wiring equipment is inserted into the lead screw, the upper part of the cross arm is locked by the half-pair-tooth self-locking nut, and finally the wiring equipment is fixed on the cross arm by a fastener.
The utility model discloses the product has solved the problem that exists among the above background art completely when the dilatation of old communication computer lab wiring equipment (chute, net, tail fiber groove etc.) is installed.
