The fastening screw is characterized in that a force receiving head is arranged at the other end of the screw body, the screw cap is of a cone-shaped structure, the screw cap is provided with a cone-shaped end face which faces towards the screw body, anti-skidding ribs which are evenly distributed are arranged on the cone-shaped face of the screw body, grooves are formed among the anti-skidding ribs, the outer threads extend to the grooves, and the force receiving groove is of a fix-flower-shaped structure. The fastening screw has the advantages of being high in locking torsion, anti-skidding and labor-saving.
Description
Technical field
The utility model relates to a kind of screw, especially a kind of fastening screw trip bolt of can two tightening that is fixed on timber plate or the sheet metal.
Background technique
Fastening screw trip bolt is generally used for parts are fixed on another support plate, especially is fixed on the support plates such as timber plate, sheet metal, in particular for fixing Volkswagen's wiper assembly position, it can not become flexible in vehicle traveling process.General, fastening screw trip bolt comprises screw body and block, block is positioned at an end of screw body, the other end of screw body has the tip, screw body is provided with outside thread, have certain distance between externally threaded root and the block, it is smooth smooth towards the end face of screw body to block a shot, and the other end of block then is provided with for the stressed cross recess of throw.The fastening screw ailing of said structure is on timber plate or sheet metal the time, at first is that tip by the fastening screw trip bolt body is pressed on and screws out a center hole on wood plank or the sheet metal, rotates into support plate by means of the contiguous outside thread extruding in tip then; Yet when support plate thickness is thicker and material is harder, the tip of fastening screw trip bolt body just is not easy to screw out center hole at support plate, and fastening screw trip bolt that therefore will be by said structure is in the fixing just effort relatively of car body, household freezer, cabinet case; In addition, cross recess on the block when screw-driver is rotated because the moment of torsion that bears is limited, skid easily and cross recess since its become to intersect vertically each other, the easy destroyed wearing and tearing of above-mentioned these orthogonal end faces make it become slick and sly when being subjected to the screw-driver rotation, be more prone to skid, reduce the working life of fastening screw trip bolt.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of torsion height, laborsaving and fastening screw trip bolt of being difficult for skidding of locking.
To achieve these goals, the technical solution adopted in the utility model is: a kind of fastening screw trip bolt, comprise screw body, one end of screw body is provided with screw nail capping, screw body is provided with outside thread, screw nail capping is provided with for the stressed stressed groove of throw, it is characterized in that: the other end of described screw body is provided with the stress head that is six flower-like structures, described block is cone-shaped structure, described block has cone shape end face towards described screw body, and the conical surface of described block is provided with equally distributed anti-skidding muscle, has groove between anti-skidding muscle and the anti-skidding muscle, described outside thread extends to described groove, and described stressed groove is six flower-like structures.
As further setting of the present utility model, described stress head is 3:1-4:1 with the length ratio of described screw body.
As further setting of the present utility model, the height of described anti-skidding muscle is 0.08-0.12mm.
As further setting of the present utility model, the number of described anti-skidding muscle is the even number of 24-36.
Adopt such scheme, when fastening screw trip bolt is screwed on the support plate, its anti-skidding muscle can be embedded into the support plate surface, increase frictional force, play anti-skidding effect, the setting of the conical surface on the block and the outside thread of screw body extend to the setting of the groove between above-mentioned anti-skidding muscle and the anti-skidding muscle, can be located at by the casing pipe sleeve that matches with this stress head shape and tighten this screw on the stress head, because this stress head is six flower-like structures, and on be set in the sleeve pipe, be difficult for skidding, more laborsaving when tightening screw; The stressed groove of last six flower-like structures of block can increase the area of contact of stressed groove and screwing tool in addition, and increase stiction prevents from skidding.This six flower-like structure distributes as six petal-shaped even structure, passes through the arc surface transition between petal and the petal.The utlity model has locking torsion higher, anti-skidding, labour-saving advantage, and screwing tool both can tighten screw by stressed groove, also can tighten screw by stress head, convenient compared with general fastening screw trip bolt.
Below in conjunction with accompanying drawing the utility model is further described.

Accompanying drawing 4 is partial enlarged drawing in the utility model accompanying drawing 1.
Embodiment
Specific embodiment of the utility model is fastening screw trip bolt shown in Fig. 1-4, comprise screw body 1, one end of screw body 1 is provided with screw nail capping 2, screw body 1 is provided with outside thread 11, screw nail capping 2 is provided with for the stressed stressed groove 12 of throw, the other end of screw body 1 is provided with stress head 13, block 2 is cone-shaped structure, block 2 has cone shape end face towards screw body 1, the conical surface 21 of block 2 is provided with equally distributed anti-skidding muscle 22, has groove 23 between anti-skidding muscle 22 and the anti-skidding muscle 22, outside thread 11 on the above-mentioned screw body 1 extends to groove 23 places, this block 2 is provided with continuously arranged arc inner cavity 24 as shown in Figure 4 with the outer circumferential face of conical surface 21 joints, stressed groove 12 be six flower-like structures as shown in Figure 2.
Above-mentioned stress head 13 is 3:1-4:1 with the length ratio of screw body 1.The height of above-mentioned anti-skidding muscle 22 is 0.08-0.12mm.The number of above-mentioned anti-skidding muscle 22 is the even number of 24-36.
Adopt such scheme, when fastening screw trip bolt is screwed on the support plate, its anti-skidding muscle 22 can be embedded into the support plate surface, increase frictional force, play anti-skidding effect, the setting of the conical surface 21 on the block 2 and the outside thread 11 of screw body 1 extend to the setting at groove 23 places between above-mentioned anti-skidding muscle 22 and the anti-skidding muscle 22, more laborsaving easier when making anti-skidding muscle 22 embed support plate, the stress head 13 of screw body 1 end is arranged so that screw body 1 is when cooperating with nut, both can act on the stressed groove 12 screw body 1 and nut screwing clamping by screw-driver, also can be located at stress head 13 outsides by the casing pipe sleeve with the stress head form fit and tighten screw body 1 and nut, the stressed groove 12 of six flower-like structures on the block 2, can increase the area of contact of stressed groove 12 and screwing tool, increase stiction, prevent from skidding.This six flower-like structure distributes as six petal-shaped even structure, passes through the arc surface transition between petal and the petal.The utlity model has the advantage that locking torsion is higher, anti-skidding, laborsaving and can two tighten.
