Abstract
The utility model relates to a knurled screw convenient to match with a spanner. The knurled screw comprises a stud, a screw head is arranged at the end of the stud, the outer edge of the screw head is of a dodecagon structure, and a plurality of protruding grains are arranged at the outer edge of the screw head; and each three protruding grains are divided into one group, and certain space is reserved between each two adjacent groups of the protruding grains. The knurled screw convenient to match with the spanner has the advantages that the structure of the screw head is changed from roundness to dodecagon so that knurling is facilitated; and the plurality of protruding grains are added to the outer edge of the screw head so that when an installation hole has deviation or the diameter of the installation hole is small, an open spanner can be conveniently used for screwing and adjusting the screw, and work efficiencies are improved.
Description
Technical field
The utility model relates to the improvement of bolt structure, relates in particular to a kind of knurled screw of cooperating with spanner be convenient to.
Background technique
As everyone knows, screw is the threaded fastener with various structure shape heads; In the industry, the existing fixing screw of drier outer panels that is used for, the general knurled screw of round end that adopts is fixed, when panel hole and bracket holes slightly have deviation, single dependence hand is tightened comparatively difficulty, because using round tack can't use interior hexagonal or spanner, this has brought many difficulties also for field maintenance and installation, has caused the reduction of working efficiency.Therefore, for above aspect, need to reasonably improve prior art.
The model utility content
For above defective, the utility model provides a kind of is convenient to adjustment that annular knurl, available open-end wrench carry out degree of tightness, be conducive to improve the knurled screw that cooperates with spanner be convenient to of work efficiency, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of knurled screw of cooperating with spanner be convenient to comprises spiro column, and described spiro column end is provided with screw head, and this screw head outer edge is the dodecagon structure and is positioned at some burrs are set on the outer edge; Per three burrs be between one group and the every two groups of adjacent burrs mutually across a certain distance.
The beneficial effect of being convenient to the knurled screw that cooperates with spanner described in the utility model is: by screw head formation is improved to dodecagon by circle, can be convenient to annular knurl; By the screw head outer edge being set up the texture of some protrusions, when mounting hole has deviation or aperture less than normal, be convenient to tighten adjustment with open-end wrench, improved work efficiency.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the described knurled screw structural representation that cooperates with spanner be convenient to of the utility model embodiment;
Fig. 2 is the screw head formation schematic representation of the described knurled screw of the utility model embodiment.
Among the figure:
1, spiro column; 2, dodecagon screw head; 3, burr.
Embodiment
Shown in Fig. 1-2, the utility model embodiment is described is convenient to the knurled screw that cooperates with spanner, comprise spiro column 1, described spiro column 1 end is provided with dodecagon screw head 2, namely this screw head outer edge is the dodecagon structure and is positioned at some burrs 3 are set on the outer edge, and per three burrs 3 are that the distance between a group and the every adjacent two groups of burrs 3 does not wait.
Above embodiment is more preferably embodiment a kind of of the utility model, and the common variation that those skilled in the art carry out in the technical program scope and replacing should be included in the protection domain of the present utility model.
Claims (2)
1. be convenient to the knurled screw that cooperates with spanner for one kind, comprise spiro column, it is characterized in that: described spiro column end is provided with screw head, and this screw head outer edge is the dodecagon structure and is positioned at some burrs are set on the outer edge.
2. the knurled screw that cooperates with spanner be convenient to according to claim 1 is characterized in that: per three burrs be between one group and the every two groups of adjacent burrs mutually across a certain distance.
