Abstract

The invention discloses an expansion swivel nut which comprises a first expansion rib and a second expansion rib. A first clamping tooth is arranged on the first expansion rib. A second clamping tooth is arranged on the second expansion rib. According to the preferred embodiment, the first expansion rib and the second expansion rib are provided with a plurality of grooves, and the first clamping tooth and the second clamping tooth are symmetrical. As the two symmetrical clamping teeth are arranged on the expansion swivel nut, the fixing performance of the expansion swivel nut is greatly improved.

Description

A kind of expansion swivel nut
Technical field
The present invention relates to a kind of articles for daily use, or rather, is a kind of expansion swivel nut.
Background technique
Setscrew in general be metallic expansive screw, setscrew is is fixedly utilize wedge shape gradient to impel expand produce friction bond stress, reach fixed effect.One, screw is screw thread, and one has tapering.Outer bread one iron sheet (having plenty of steel pipe), iron sheet cylinder (steel pipe) half has some otch, they are filled in hole that wall is accomplished fluently together, then split nut, nut pulls outward screw, tapering is drawn in iron sheet cylinder, and iron sheet cylinder is by spreading, so tightly fixing on the wall, be generally used for fastening on the material such as cement, brick such as protective grating, canopy, air-conditioning.But its is fixing very unreliable, if load has comparatively big bang, may getting loose, therefore not recommending for installing ceiling fan etc.
In the using process of swell fixture, situation about much coming off is all because expansion swivel nut can not retaining screw be relevant well.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus provides a kind of expansion swivel nut that effectively can improve setscrew fixed performance.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of expansion swivel nut, comprise one first expansion muscle and one second expansion muscle, the first described expansion muscle is provided with one first latch, and the second described expansion muscle is provided with one second latch.
As preferred embodiment of the present invention, the first described expansion muscle and the second expansion muscle are provided with some grooves.
As preferred embodiment of the present invention, the first described latch and the second latch symmetrical.
Be provided with two symmetrical latches because expanding screw of the present invention puts, thus substantially increase the fixed performance of setscrew.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective view of expansion swivel nut of the present invention;
Fig. 2 is the perspective view of the expansion swivel nut in Fig. 1, is now another visual angle.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The invention provides a kind of expansion swivel nut that effectively can improve setscrew fixed performance.
As shown in Figure 1 and Figure 2, a kind of expansion swivel nut 1, comprise one first expansion muscle 21 and one second expansion muscle 22, the first described expansion muscle 21 is provided with one first latch 31, and the second described expansion muscle 22 is provided with one second latch 32.
As shown in Figure 1 and Figure 2, the first described expansion muscle 21 and the second expansion muscle 22 are provided with some grooves 4.
As shown in Figure 1 and Figure 2, the first described latch 31 and the second latch 32 symmetrical.
The expanding screw of this invention puts and is provided with two symmetrical latches, thus substantially increases the fixed performance of setscrew.
Below only in one embodiment mentality of designing of the present invention is described, when system allows, the present invention can expand to external more function module simultaneously, thus expands its function to greatest extent.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
