Abstract
The utility model discloses a screw coupling. The screw coupling comprises a nut, a screw bolt or a screw which is cooperated with the nut. A straight-line slot, a cross slot or an inner hexagon slot which is used for fixation is arranged on the tail end face of the screw bolt or the screw; so one end of the screw coupling which can be sheathed with the nut is fixed by the tool, the space which is caused by the clamping of the screw bolt or the screw can be omitted, and more compact structure can be realized.
Description
The utility model is relevant with thread connector, is specifically related to the structure of the terminal surface of the bolt that matches with nut or screw.
In connecting operation, nut cooperates with bolt, turns nut, and bolt (or screw) and then rotates.Fastening in order to connect, with instruments such as wrench bolt (or screw) is clamped usually, turn nut again.Existing bolt (or screw) all has can be for the head of clamping.Head has multiple structure: hexagon, square, circular; Head end also has multiple structure: straight groove, cross recess, interior hexagonal.But, all do not supply the structure of tool holding at the terminal surface of all bolts, screw.In following occasion, head and head end structure for clamping are only arranged, and have for the fixing terminal surface structure of usefulness, it is quite difficult connecting operation: one, the head of bolt (or screw) is in the narrow and small position that is not easy to the instrument of putting to good use, as in slit, the chamber, at the bottom of the support etc.; Two, coupled more roomy, as wallboard, dish cabinet etc., worker's both hands can't be taken into account the two ends of the bolt that is spaced (screw) simultaneously, need two people operation simultaneously this moment.
The purpose of this utility model is to improve the structure of bolt, tip of screw face, provides a kind of thread connector of being convenient to connect operation to the public.
The utility model provides from accompanying drawing and embodiment.
This coupling is made up of nut (1) and bolt or screw (2).Bolt or screw (2) are divided into head (3), screw rod (4) and terminal surface (5) again.Terminal surface (5) has straight groove (6) or cross recess (7) or interior hexagonal (8) according to the size of standard piece, and impact briquetting during fabrication.
Description of drawings:
The schematic representation of Fig. 1 thread connector
Fig. 2 thread connector terminal surface has the schematic representation (being first kind of left view of Fig. 1) of straight groove
Fig. 3 thread connector terminal surface has cross recessed schematic representation (being second kind of left view of Fig. 1)
The schematic representation (being the third left view of Fig. 1) of hexagonal in Fig. 4 thread connector terminal surface has
This connector has two big advantages: the available instrument of an end that one is inserted in nut is fixed; It two can save the space that is generally grip bolt (or screw) and stays, and makes equipment more compact.
Claims (1)
1, thread connector, form by bolt that matches with nut (1) or screw (2), the head of bolt or screw (2) can be hexagon, square, circular, can open hexagonal in straight groove, the cross recess on the end face of head, it is characterized in that, on the terminal surface (5) of bolt or screw (2), have straight groove (6), or cross recess (7), or interior hexagonal (8).
