Abstract

The utility model relates to a screw bolt connecting piece used for fastening frames, particularly a fastening anti-loosing connecting device being suitable to be used between two endpoints or between one point and multiple points. The utility model is mainly composed of a screw bolt and a screw nut frame. The screw bolt is a hook-shaped screw bolt, one end forms a hook shape, the other end is provided with an external thread, the screw nut frame is a polygon, and an internal screw thread hole matched with the external screw thread of the hook-shaped screw bolt is opened on each side. The connecting piece has a simple structure and is suitable for multiple directions, and the tightness can be adjusted at random.

Description

A kind of clamping bolt coupling

The utility model relates to the bolt connection part that a kind of fastening framework is used, and is particularly useful between two end points or a bit and the fastening locking coupling arrangement of using between the multiple spot.

The fastening connection piece that uses in the prior art generally is made up of bolt and nut, and fastening by nut, adjustment range is little; Chinese patent application discloses a kind of tightening nut, and the patent No. is 93230311.0, and it is a kind of hook-type nut, one end is a hook-type, and an end is an internal thread, is connected with the bolt of fixing by internal thread, with the object tension of installing, its defective is the fastening connection that only is applicable on some directions.

The purpose of this utility model is to overcome defective of the prior art and the suitable multi-faceted and fastening unit that can arbitrarily adjust degree of tightness that designs.

Accompanying drawing 1 is a structural representation of the present utility model;

The purpose of this utility model is achieved in that it by the screw bolt and nut system framework, and bolt is One hook bolt, 2, one ends are hook-type, and the other end is provided with external screw thread; Nut framework 1 is a polygon, and is every All have the internal thread hole that matches with the hook bolt external screw thread on the individual limit, when mounted, can be with hook-type Bolt 2 is installed on the fixing bolt 3, and hooking with the hook end of hook bolt 2 needs fastening thing Part is installed in hook bolt 2 on the nut framework 2 again, adjusts hook bolt 2 on nut framework 1 Advance and retreat position in the internal thread hole, object that just can need are fastening is strained or is loosened.

Advantage of the present utility model: simple in structure, easy operating is specially adapted to point-to-point transmission or is the fastening of link between the multiple spot more than 2, and can arbitrarily adjust its tightness, and is applied widely.

The utility model will be further described below in conjunction with accompanying drawing:

The utility model is made up of hook bolt 2 and nut framework 1, one end of hook bolt 2 is a hook-type, the other end is an outside thread, nut framework 1 can be a quadrilateral, on its four limits, all have the interior threaded hole that matches with the outside thread of hook bolt, hook bolt 2 can be installed on the nut framework 1, when needs carry out being fastenedly connected on three directions, one side of hook bolt 2 can be connected with the bolt of fixing 3, three objects that need are fastening hang on three hooks of hook bolt 2, turning hook bolt 2 can strain the fastening piece on three directions, during fastening coupling between as 2 o'clock, the iron wire of using as fastening extension curtain, two nut frameworks 1 can be separately fixed on the fixing bolt 3 of two-end-point, iron wire be hung on the hook of hook bolt 2, turn the advance and retreat of hook bolt 2 on nut framework 1, can or loosen the iron wire tension, make the more neat of Curtain suspension device.

Nut framework of the present utility model can be made into triangle, three limits all can have interior threaded hole and match with the outside thread of hook bolt, when triangle nut framework connected fastening piece as the centre, three tapped holes can cooperate adjustment with three hook bolts, the link of three different direction; If link to each other with a fixing bolt 3 on one side, two holes can be adjusted in addition, and other both direction connects the degree of tightness of object.

Claims

1, a kind of clamping bolt coupling is made up of the screw bolt and nut framework, it is characterized in that bolt is a hook bolt (2), and an end is a hook-type, and the other end is provided with outside thread; The nut framework is a polygonal, all has the interior threaded hole that matches with the hook bolt outside thread on each limit.

2, clamping bolt coupling according to claim 1 is characterized in that the nut framework can be quadrilateral or triangle, all has the interior threaded hole that matches with the hook bolt outside thread on its each limit.
