Abstract
The utility model discloses an embedded screw sleeve, which comprises a head and a tail which are connected with each other, wherein the tail is a boss; the head is internally provided with an internal thread; and the internal and external walls in the joint of the head are provided with a chamfer respectively. The embedded screw sleeve has the advantages that the positions of the screw sleeve inserted into a thin plate and a thin-wall tubular product can be controlled by the boss of the tail; the connection strength and reliability can be ensured by the internal thread of the head; and furthermore, due to the chamfers in the joint of the head, the screw sleeve can be inserted in the preset holes of the thin plate and the thin-wall tubular product conveniently and a fastener can be screwed into the screw sleeve conveniently. The embedded screw sleeve has the effects of simplicity in operation, practicality and safety, and reliability in connection.
Description
Technical field
The utility model relates to link, particularly a kind of embedded swivel nut.
Background technique
General traditional thin plate, Placement between the thin-wall pipes has following several: a kind of is to thicken at the fixed end place, the tapping of holing again, with screw the thin-walled material of thin-wall pipes and fixed end is fixed, this mode in the fixed end thickening is only applicable to large caliber pipe mouth, then unavailable for slender pipe, pipe external upset (EU) tapping, long spiro nail is fixed, and screw is not easy docking when assembling; A kind of is to add welded nut at fixed end, and its shortcoming also is that screw is not easy to aim at when assembling; A kind of is to fix with bolt, nut docking, although this method is convenient, be under the enclosed structure at fixed end, or the material platform is thin, and this mode just can't have been accomplished.Therefore provide a kind of simple to operate, easy to use, connect safe and reliable embedded swivel nut.
The model utility content
The purpose of this utility model is that a kind of embedded swivel nut easy to connect, simple to operate will be provided.
According to an aspect of the present utility model, the embedded swivel nut that provides, it comprises: interconnective head and afterbody, afterbody is a boss, the diameter of head is less than the diameter of described afterbody, its beneficial effect is, can well control swivel nut by the boss of afterbody and insert relevant position on the thin-wall pipes, and head diameter is in order to make things convenient for swivel nut to insert in the hole on the thin-wall pipes greater than tail diameter.
In some embodiments, comprise that also head is provided with internal thread, its beneficial effect is, head is the attachment portion of swivel nut and fastening piece, and internal thread is the key position that connects.
In some embodiments, comprise that also reach equals 1.2 times of major diameter of thread, its beneficial effect is that the intensity that makes screw thread have enough length assurances to connect is unlikely to again the convenience that long impact is used.
In some embodiments, comprise also that swivel nut is inner and be hollow cylindrical, its beneficial effect is, namely guaranteed swivel nut intensity, saved again material.
In some embodiments, also comprise the diameter of hollow cylinder greater than the large footpath of internal thread, its beneficial effect is, screws at fastening piece not to be subjected to stopping of inwall when passing internal thread, guaranteed the safety of swivel nut itself and fastening piece.
In some embodiments, head and afterbody are provided with continuous internal thread, and its beneficial effect is to increase the thickness of connection part, safety and reliability that assurance connects.
In some embodiments, comprise that also all there is chamfering on head jointing inside and outside wall limit, its beneficial effect is that hole and the fastening piece that can more make things convenient for swivel nut to insert on the thin-wall pipes screw in the swivel nut.
