Detailed description of the invention
Buckle as shown in Figures 2 and 3, is formed by single metal wire bending, such as iron wire, copper wire or its B alloy wire, including
Form the base 3 of annular, base 3 the top shoulder radially extended to the ring heart along helical buckling by the first end 5 wiry
4, shoulder 4 cervical region 2 formed after upwardly extending, cervical region 2 form the resilient head 1 of tool after bending；It is connected with head 1
Second end 5 is bending after-contraction in cervical region 6 position.
Spiral on base 3 radially extends to the ring heart to turn back on backward and is formed and for limiting the U-shaped bayonet socket 7 of sealing strip,
It is connected restraining position ring block limit 8 between this U-shaped bayonet socket 7 with shoulder 4.
In the present embodiment, U-shaped bayonet socket 7 has the first longitudinal edge 10 and the second longitudinal edge 11 setting up and down, and connects
Axial limit 12 between two longitudinal edges, this axial limit 12 is positioned at the axial line (being equivalent to the axis through the ring heart) of base 3
On.Wherein, the first longitudinal edge 10 is formed after the ring heart radially extends by base spiral, and axial limit 12 is by the first longitudinal edge 10 upwards
Being bent to form, the second longitudinal edge 11 is bent outwardly by axial limit 12 after turning back and is formed.Spacing ring limit 8 connects the second longitudinal edge 11 He
Shoulder 4, is specially the arc limit obtained by the second longitudinal edge 11 to shoulder 4 bending extension, and the radius on this arc limit is equal to the half of base 3
Footpath.
As shown in Figure 4, after base 3 screws in sealing strip 4, the entry of stab wound on sealing strip 4 is made to be set at U-shaped bayonet socket,
Thermal insulation layer and wire netting are positioned at upper and lower two longitudinal edges, utilize the spacing ring limit 8 arranged, the head of buckle can be avoided to drop into
In thermal insulation layer and wire netting, if the buckle installing hole simultaneously on baking box exists burr, it can also protect sealing strip not by burr
Scratch.It addition, for make the screw-in of base 3 easily facilitate operation, make the first end 5 tilt the bottom at base；And first end 5
There is the tip being beneficial to thrust, it is simple to thrust in sealing strip.
Flush with shoulder 4 after opposite shoulder 4 back-flexing at neck location of second end 6, and bending so that the second end
End 6, under the stop on shoulder and spacing ring limit, can avoid its thermal insulation layer of scratch sealing strip when loading sealing strip.
In the present embodiment, on the extension line of shoulder 4 longitudinal edge above, i.e. bending shape after bent 180 degree of spacing ring spring
Become shoulder 4 so that shoulder and radially above limit, from two opposite sides position limiting sealed bar, have the effect more preferably protecting sealing strip.
Plane residing for head 1 is perpendicular to base 3, and the cervical region 2 being connected with head 1 is axially extending along the base 3 ring heart.Head
The tinsel bending of position is tetragon, and a diagonal of this tetragon is positioned on the axial line of base, is on diagonal
The insertion end that angle 9 is head 1 in portion, makes tetragon deformation, upon full insertion by two limits at extruding angle 9 in insertion process
Recovering to be fixed in installing hole, other one jiao on diagonal is connected with cervical region 2.
The foregoing is only preferable implementation example of the present utility model, be not limited to this utility model, all in this reality
Within novel spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in guarantor of the present utility model
Within the scope of protecting.
