Description
Technical field
The utility model relates to a kind of fastening piece, particularly relates to a kind of catch bolt device.
Background technique
It is form common in anatomical connectivity that bolt connects, and is usually used in the position of structure or the maintenance of equipment needs.Bolt connection is generally demountable structure and takes the bolt/nut of standard to be connected with base, its Problems existing needs two pieces instrument when being and installing, one end is fixed, the other end is tightened, due to the restriction in path and space during practical set, usually at one end can only use instrument, cause structure disassembling operations difficulty.
Therefore, need to provide a kind of new technological scheme to solve the problems referred to above.
Model utility content
The utility model technical issues that need to address are to provide a kind of catch bolt device of easy accessibility.
For solving technical problem of the present utility model, the technical solution adopted in the utility model is:
A kind of catch bolt device, it comprises dogbolt, nut, packing ring, demountable structure, base, standard bolt assembly and base and to be connected auricle, the bolt head end face of described dogbolt is with U-type groove, after dogbolt inserted base and demountable structure, standard bolt assembly is stuck in the U-type groove of dogbolt, and be connected and fixed with the base auricle that is connected, described dogbolt and base connect as one, and described dogbolt afterbody installs packing ring and nut.
Further, described base is connected on auricle and has stop attachment hole.
The beneficial effects of the utility model: catch bolt device of the present utility model, there is dogbolt, its bolt head end face is with U-type groove, matching standard bolt uses, need design stop attachment hole on base is connected auricle, dogbolt is existing prevents axial rotation function, prevents the function that slides axially again, can be used for bolt one end and the bad position of path is installed, improve the maintainability of structure.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Following examples, only for illustration of the utility model, are not used for limiting protection domain of the present utility model.
As shown in Figure 1, a kind of catch bolt device of the present utility model, it comprises dogbolt 1, nut 2, packing ring 3, demountable structure 4, base 5, standard bolt assembly 6 and base and to be connected auricle 7, the bolt head end face of dogbolt 1 is with U-type groove 8, after dogbolt 1 inserted base 5 and demountable structure 4, standard bolt assembly 6 is stuck in the U-type groove 8 of dogbolt 1, and be connected and fixed with the base auricle 7 that is connected, dogbolt 1 and base 5 connect as one, and dogbolt 1 afterbody installs packing ring 3 and nut 2.Because standard bolt assembly 6 can apply moment of flexure and axial direction applied thrust in dogbolt 1 radial direction, Anti-fall function when namely realizing dogbolt 1 anti-rotation and dismounting.
The bolt head end face of dogbolt 1 is with U-type groove 8, and matching standard bolt uses, and need have stop attachment hole 9 on base is connected auricle 7.
Above-mentioned demountable structure 4 is the component connected together with base 5.Demountable structure 4 and base 5 can according to using needs, carry out splitting or being linked to be entirety, when dismounting is subject to the restriction in path and space, dogbolt 1 matching standard bolt assembly 6 of the present utility model is arranged on base 5, dismounting packing ring 3 and nut 2 can realize the dismounting of demountable structure 4, very convenient.
As shown in Figure 1, this kind of dogbolt 1, its bolt head end face is with U-type groove 8, and matching standard bolt assembly 6 uses, and need design stop attachment hole 9 on base is connected auricle 7.Dogbolt 1 is existing prevents axial rotation function, prevents the function that slides axially again, can be used for bolt one end and installs the bad position of path, improve the maintainability of structure.
Dogbolt is installed first: by dogbolt 1 inserted base 5, standard bolt assembly 6 is inserted at base auricle 7 through hole that is connected, and be stuck in the U-type groove 8 of dogbolt 1, standard bolt assembly 6 is fixed on base to be connected auricle 7, load demountable structure 4, finally load the installation that namely packing ring 3, nut 2 complete dogbolt 1.
Dogbolt 1 is dismantled: only need with tool ejector nut 2, packing ring 3, then dismantles demountable structure 4 and namely completes dismounting.
Claims (2)
1. a catch bolt device, it is characterized in that: it comprises dogbolt, nut, packing ring, demountable structure, base, standard bolt assembly and base and to be connected auricle, the bolt head end face of described dogbolt is with U-type groove, after dogbolt inserted base and demountable structure, standard bolt assembly is stuck in the U-type groove of dogbolt, and be connected and fixed with the base auricle that is connected, described dogbolt and base connect as one, and described dogbolt afterbody installs packing ring and nut.
2. a kind of catch bolt device according to claim 1, is characterized in that: described base is connected on auricle and has stop attachment hole.
