Abstract

The utility model relates to a screw, which comprises a threaded rod (1). The screw is characterized in that the threaded rod (1) is in an L shape, and an outer screw thread is arranged on the outer wall of at least one supporting arm in two supporting arms of the L-shaped threaded rod. Compared with the prior art, the screw has the advantages that two screws do not need respectively penetrating from different direction for fixation when objects are fixed on different parts of one pipe body through designing the threaded rod into an L shape, the screw can be used conveniently, and can save materials and save more time, the pipe body is more beautiful on appearance after objects are fixed, and the screw is extremely suitable for extension and application.

Description

A kind of screw

Technical field

The utility model relates to a kind of screw.

Background technique

Existing screw generally comprises screw rod and is arranged on the land at screw rod top, and screw rod is the straight cylinder type, on the screw rod outer wall outside thread is set.

When on the different parts that different objects need be fixed on same body, must fix object respectively from different directions with screw, for example: in the time of two articles 1 ', 2 ' need being fixed on the not coplanar of cylindricality body 3 ', as shown in Figure 1, must adopt two screws 4 ', 5 ' pass respectively two articles 1 ', 2 ' and cylindricality body 3 ' on screw, use two nuts 6 ', 7 ' to fix then.

There is bigger narrow limitation in the screw of this structure during use, need many screws at position, many places fixed object.

The model utility content

Technical problem to be solved in the utility model be at above-mentioned prior art provide a kind of on the different parts of a body, need not during fixed object two screws respectively from different directions penetrate fixing, easy to use, economize material timesaving screw.

The utility model solves the problems of the technologies described above the technological scheme that is adopted: this screw, comprise a screw rod, and it is characterized in that: described screw rod is the L type, and has at least the outer wall of a support arm to be provided with outside thread in two support arms of described L type screw rod.

As improvement, the second support arm outer wall of described L type screw rod is provided with outside thread, and is movably set with lock nut on the second support arm outer wall of this described L type screw rod; The top of first support arm of described L type screw rod is provided with the land.

The angle that bends between first support arm of described L type screw rod and second support arm is between 30 °～160 °.

Compared with prior art, advantage of the present utility model is: by screw design being become L type result, need not when making fixed object on the different parts of a body two screws respectively from different directions penetrate fixing, screw is easy to use, economizing material more saves time, body behind the fixed object is more attractive in appearance in appearance, is fit to very much apply.
