Abstract
The utility model relates to a screw bolt and screw nut assembly, which comprises a connecting plate, wherein a connecting hole used for passing a screw nut is formed on the connecting plate, the cross section of the bottom of the screw nut is greater than the cross section of the head part, the head part of the screw nut is provided with an outward flange, the outline formed by the outer edge of the flange is wider than the outer edge of the connecting hole, and the screw bolt and screw nut assembly also comprises a screw bolt matched with the screw nut. The screw bolt and screw nut assembly has a simple structure. When the screw bolt and screw nut assembly is adopted, the smooth, convenient and fast operation can also be realized on places which can not be reached by the hands of people or a tool, the operation of a worker is convenient in the whole working process, the work load of the worker is reduced, and the working efficiency is improved.
Description
Technical field
The utility model relates to technical field of fastening, specifically, relates to a kind of bolt and nut component, is particularly useful for the blind dress in the small space.
Background technique
Adopting bolt and nut to connect is a kind of common mode that is fastenedly connected, and is used for multiple occasion, can both satisfy fastening needs generally speaking.But in reality, much often the space is narrow and small at the position that need be fastenedly connected, and makes us hand and operation tool and all is difficult to enter, and inconvenient operation has had a strong impact on work efficiency of workers.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of bolt and nut component simple in structure is provided.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of bolt and nut component, comprise connecting plate, described connecting plate is provided with and is used for the attachment hole that nut passes, the cross-section area of described nut bottom is greater than the cross-section area of head, described nut head is provided with outside flange, the profile that described flange outer rim forms is wider than the outer rim of attachment hole, also comprises the bolt with the nut coupling.
It between described nut and the attachment hole Spielpassung.
The outer rim of described flange forms the barb tooth to the bending of nut bottom.
Described connecting plate is provided with at least two attachment holes that lay respectively at the connecting plate two ends.
Repeated hole is reduced at described connecting plate middle part.
The beneficial effects of the utility model are:
1. bolt and nut component of the present utility model, simple in structure, only need are changed a little on prior art and are got final product, and realize being fastenedly connected of small space easily;
2. after connecting plate being stretched into position to be connected, hand does not need to stretch into the inside again, the Bolt Connection in just can carrying out, and the unapproachable place of staff and instrument also can realize operating easily smoothly;
3. in design process, though consider in the small space and stretch into, may have the difficult right problem of bolts and nuts, so the utility model has just designed the Spielpassung between nut and the connecting plate without hand and instrument, can become flexible but do not come off, bigger adjustment space is arranged;
4. the workman is easy to operate in entire work process, has reduced workman's workload, has improved working efficiency.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Embodiment: referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4.
A kind of bolt and nut component, comprise connecting plate 1, described connecting plate 1 is provided with and is used for the attachment hole 3 that nut 2 passes, the cross-section area of described nut 2 bottoms is greater than the cross-section area of head, described nut 2 heads are provided with outside flange 4, the profile that described flange 4 outer rims form is wider than attachment hole 3, also comprises the bolt 5 with nut 2 couplings.The cross-section area of nut 2 bottoms is greater than the cross-section area of head, and the profile that flange 4 outer rims form is wider than attachment hole 3, and such structural design makes the nut that has flange 4 can not come off from connecting plate.
Preferably, be Spielpassung between nut 2 and the attachment hole 3, this makes in assembly process, can carry out certain adjustment between nut 2 and the connecting plate 1.
Preferably, the outer rim of flange 4 forms the barb tooth to the bending of nut 2 bottoms, like this, can make the barb tooth of nut 2 in bolt 5 connection procedures and connecting plate 1 that interlock takes place, and is difficult for rotating.
Adopt the utility model to carry out being fastenedly connected of small space, may further comprise the steps:
The first step penetrates attachment hole 3 on the connecting plate 1 with nut 2 heads, and the cross-section area of described nut 2 bottoms is greater than the cross-section area of head;
Second step, open outside flange 4 at nut 2 heads, the profile that described flange 4 outer rims form is greater than the outer rim of attachment hole 3;
The 3rd step, connecting plate 1 is stretched into small space among Fig. 4, make nut 2 heads aim to be connected attachment hole, perhaps stretch out to be connected attachment hole;
The 4th step buttressed connecting plate 1 outer rim, adopted the bolt 5 that mates with nut 2 that to be connected is fastenedly connected.
Preferably, be Spielpassung between nut 2 and the attachment hole 3, this makes in assembly process, can carry out certain adjustment between nut 2 and the connecting plate 1.
Preferably, the outer rim of flange 4 forms the barb tooth to the bending of nut 2 bottoms, like this, can make the barb tooth of nut 2 in bolt 5 connection procedures and connecting plate 1 that interlock takes place, and is difficult for rotating.
Embodiment two: referring to Fig. 5, and Fig. 6.
Do not give unnecessary details with embodiment one something in common, difference only is,
A kind of bolt and nut component, connecting plate 1 are provided with at least two attachment holes that lay respectively at connecting plate 1 two ends, and two groups of bolt and nuts are fastening;
Embodiment three: referring to Fig. 7.
Basic identical with embodiment two, difference only is that in the present embodiment, repeated hole 6 is reduced at connecting plate 1 middle part, both can economical with materials, can alleviate the weight of connecting plate 1 self again.
