Description
Technical field
This utility model is related to Gekko Swinhonis bolt.
Background technology
With the continuous development of urbanization, the reinforcing of building also constantly requires to increase；The fastening of plain screw is not
Can meet and require, there are window Gekko Swinhonis using more at present, window Gekko Swinhonis occur grabbing showing for wall shakiness in use, often
As analyzing its reason is：Installing hole is larger, and shell expansion is limited, and the frictional force between shell and body of wall is less.
The content of the invention
The purpose of this utility model be solve the deficiencies in the prior art, there is provided a kind of Gekko Swinhonis bolt, the Gekko Swinhonis bolt with
Body of wall combines fastening, stablizes.
The technical scheme that this utility model is adopted for achieving the above object for：
A kind of Gekko Swinhonis bolt, including the housing and Gekko Swinhonis bullet core of one end open tubular, Gekko Swinhonis bullet core include the connection of column
Portion and conical head, housing are provided with the expanding end being engaged with conical head and the link slot being engaged with connecting portion, Gekko Swinhonis bullet core
Connecting portion through expanding end insert link slot, expanding end is provided with a plurality of gap, and the outer surface of expanding end is provided with a plurality of parallel
The cannelure of setting, and the depth of cannelure is more than the 1/5 of expanding end thickness.
Preferably, the expanding end is provided with through hole, is provided with and grabs wall nail in through hole.
Further, the expanding end is internally formed the bellmouth being engaged with conical head.
Preferably, the taper of conical head and bellmouth is 1/16.
Further, the end in the gap is provided with circular port.
The beneficial effects of the utility model are：This utility model increases the depth of cannelure, effectively by designing cannelure
Increase the frictional force with body of wall, fastening is combined with body of wall, is stablized.
Description of the drawings
Fig. 1 is a kind of schematic diagram of the present utility model.
Fig. 2 is another kind of schematic diagram of the present utility model.
Reference is：
1 --- housing；2 --- Gekko Swinhonis bullet core；3 --- link slot；4 --- cannelure；5 --- circular port；6 --- seam
Gap；7 --- expanding end；21 --- conical head；22 --- connecting portion；8 --- grab wall nail.
Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is further described.
Embodiment 1：Referring to Fig. 1 to Fig. 2.
A kind of Gekko Swinhonis bolt, including the housing 1 and Gekko Swinhonis bullet core 2 of one end open tubular, Gekko Swinhonis bullet core 2 include the company of column
Socket part 22 and conical head 21, housing 1 are provided with the expanding end 7 being engaged with conical head 21 and the connection being engaged with connecting portion 22
Groove 3, the connecting portion 22 of Gekko Swinhonis bullet core 2 insert link slot 3 through expanding end 7, and expanding end 7 is provided with a plurality of gap 6, and expanding end 7
Outer surface be provided with a plurality of cannelure 4 be arrangeding in parallel, and the depth of cannelure 4 is more than the 1/5 of 7 thickness of expanding end.
The outer surface of expanding end 7 typically adopts latticed groove at present, as groove is than comparatively dense, therefore the depth of groove
It is relatively deep that degree is difficult to do, and when being combined with body of wall, groove can be filled up by wall ash, so as to reduce frictional force.In the technical program,
Design spaced annular groove so that the depth of groove can design relatively deep, so as to avoid being filled, with body of wall it
Between keep larger frictional force.
Preferably, the expanding end 7 is provided with through hole, is provided with and grabs wall nail 8 in through hole.
Gekko Swinhonis bolt when in use, Gekko Swinhonis bullet core 2 is inserted in installing hole, then taps the blind end of housing 1, Gekko Swinhonis
Connecting portion 22 steps into link slot 3, and expanding end 7 also progressively by distending, will gradually grab wall nail 8 and eject, and insert by conical head 21
In body of wall, so as to further increase frictional force.Preferably, through hole is linearly arranged, and grabs the length of wall nail 8 from the inside to the outside gradually
Increase；Can so cause the lateral distance for grabbing the outer face to conical head 21 that wall follows closely 8 equal or suitable.The closing of Gekko Swinhonis bolt
Hold for welding object, such as hook etc..
Further, the expanding end 7 is internally formed the bellmouth being engaged with conical head 21, it is preferable that conical head 21
1/16 is with the taper of bellmouth.
When bellmouth inside the expanding end 7 is engaged in conical head 21, conical head 21 when into expanding end 7, taper
21 are contacted with 7 face of expanding end, and contact area is big, prevents linear contact lay from deforming.Secondly, as conical head 21 deepens continuously, expansion
The rate of change of amount is increasing.For convenience of the insertion of conical head 21, through test, when taper is 1/16, expansion speed can be taken into account
Degree and insertion difficulty.
Further, the end in the gap 6 is provided with circular port 5.
After arranging circular port 5, the rounded setting in end in gap 6 can prevent expanding end 7 in expansion, and housing 1 bears
Larger shearing stress, ruptures in 6 end of gap, causes whole housing 1 to split.
This utility model has been made to explain, it will be understood by those within the art that, can be new to this practicality
The technical scheme of type is modified or equivalent, without deviating from the spirit and scope of technical solutions of the utility model.
