Abstract
Description
Technical Field
[0001] The utility model relates to a double-head butterfly bolt. Background Art
[0002] A butterfly bolt is a bolt composed of a stud and a butterfly head. With the help of the butterfly head, users can tighten or loosen the stud by hand, so that the stud can be screwed into or out of the threaded hole. However, with the widespread use of butterfly bolts, butterfly bolts have begun to be used for temporary clamping between some panels. However, since most of these panels are not provided with threaded holes, butterfly bolts need to be used with nuts, and therefore also require a wrench, which is inconvenient to use.
[0003] Therefore, it is necessary to make further improvements. Utility Model Content
[0004] The utility model aims to overcome the above problems and provides a double-headed butterfly bolt, which has the advantages of being easy to use and not relying on threaded holes.
[0005] To achieve the above-mentioned purpose, the utility model provides a double-headed butterfly bolt, which includes a stud, a butterfly head and a butterfly nut. The butterfly head is fixed on one end of the stud, the butterfly nut is screwed on the stud and arranged opposite to the butterfly head, and a clamping space is formed between the butterfly nut and the butterfly head.
[0006] In one or more embodiments, a first gasket is disposed on the butterfly head, and a second gasket is disposed on the butterfly nut.
[0007] In one or more embodiments, the first gasket is fixed to the butterfly head or the stud by welding, and the second gasket is fixed to the butterfly nut by welding.
[0008] In one or more embodiments, the first gasket and the second gasket have the same circular diameter, and both the first gasket and the second gasket are stainless steel gaskets.
[0009] In one or more embodiments, the butterfly nut includes a nut body and a butterfly portion, the butterfly portion is welded and fixed to the nut body, and the butterfly portion is provided with an escape opening for escaping the stud.
[0010] In one or more embodiments, the outer surface of the nut body is hexagonal or pentagonal.
[0011] In one or more embodiments, the length of the stud is 5CM-30CM.
[0012] In one or more embodiments, the stud, butterfly head and butterfly nut are made of stainless steel or plastic.
[0013] Compared with the background technology, the utility model has the following effects: the double-headed butterfly bolt is composed of a stud, a butterfly head and a butterfly nut. When using, the user only needs to twist the butterfly nut to switch the clamping and loosening states of the double-headed butterfly bolt. It can be used by hand without the aid of tools, and has the advantages of easy operation and convenient use. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 It is a schematic structural diagram of a double-headed butterfly bolt according to an embodiment of the utility model. DETAILED DESCRIPTION
[0015] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.
[0016] Please see attached Figure 1 The present application provides a double-headed butterfly bolt, which includes a stud 1, a butterfly head 2 and a butterfly nut 3. The butterfly head 2 is fixed to one end of the stud 1, and can be fixed by welding. The butterfly nut 3 is screwed on the stud 1 and arranged opposite to the butterfly head. A clamping space is formed between the butterfly nut 3 and the butterfly head 2. When in use, the butterfly nut is first unscrewed, the stud passes through one end of the plate and extends out from the other end of the plate, and then the butterfly nut is re-screwed onto the stud, and the butterfly nut is continuously turned to approach the butterfly head, and finally the plate is clamped and fixed.
[0017] The butterfly head 2 is provided with a first gasket 4, and the butterfly nut 3 is provided with a second gasket 5. The first gasket and the second gasket can protect the plate from direct contact with the butterfly head and the butterfly nut to avoid scratches or wear.
[0018] The first gasket 4 is welded and fixed on the butterfly head 2 or the stud 1, and the second gasket 5 is welded and fixed on the butterfly nut 3, thereby preventing the first gasket and the second gasket from being lost.
[0019] The first gasket 4 and the second gasket 5 have the same circular diameter, and both the first gasket and the second gasket are stainless steel gaskets, which have the advantages of corrosion resistance and good structural strength.
[0020] The butterfly nut 3 includes a nut body 31 and a butterfly portion 32. The butterfly portion is welded and fixed to the nut body, and the butterfly portion is provided with an escape hole for escaping the stud, and the escape hole corresponds to the threaded hole on the nut body. Preferably, the outer surface of the nut body is hexagonal or pentagonal, and when the butterfly portion is damaged and cannot be used, the nut body can be twisted with a wrench.
[0021] The length of the stud 1 is 5CM-30CM, and the specific length is produced according to actual needs to meet the needs of different plate thicknesses and different usage scenarios.
[0022] The stud 1, butterfly head 2 and butterfly nut 3 are made of stainless steel or plastic. The appropriate material is selected according to the actual production needs and application scenarios. For fixing some plastic panels, double-headed butterfly bolts made of plastic can be used. For some panels with higher hardness, double-headed butterfly bolts made of stainless steel can be used.
[0023] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
