Abstract
A kind of rotary self-locking bolt, casing is hollow to be equipped with screw hole, and screw rod matches with screw hole, and sleeve edge is equipped with fricting strip, and barrier tape made of the multiple strip slot intervals of casing other side integrally connected, barrier tape connector sleeve point, set is sharp to be equipped with screw hole to casing side.Barrier tape rotation is driven by rotary screw using the present apparatus, forms pretightning force, it is easy to operate.
Description
[technical field]
The utility model relates to a kind of bolts, and in particular to one kind is convenient for must fastener across wall or other objects
The rotary self-locking bolt of fastening.
[background technique]
Bolt is applied to the every field such as industrial daily life.And expansion bolt is to consolidate pipeline branch/hang/bracket or equipment
A kind of fixed special thread connector on the wall, on floor, used on column.In use, first electric impact drill (hammer) must be used in fixation
The hole of corresponding size is drilled out on body, then in bolt, tube expansion load hole, tightening nut can make bolt, tube expansion, installation part and consolidate
Determine swelling between body to be integrally formed.Dilatable after tightening, bolt tail has a major part, and the outer surface cover one of bolt compares bolt
Slightly larger round tube of diameter, the tail portion road part You Ji opening, after bolt is tightened, the tail portion of major part is just brought to opening
Inside pipe, pipe is rushed greatly, achievees the purpose that expansion, and then bolt is fixed on ground or wall, reaches the mesh taken root
's.
Pretightning force generated in existing expansion bolt use, the rigidities shadow such as the wall installed, floor, door pillar
It rings, if fixed body autologous density is lower, tube expansion is easy for being detached from fixed body, therefore falls off together with installation part, influences actually to make
Use effect；Fixed body must drill out the hole with tube expansion corresponding size simultaneously, otherwise can not form pretightning force.
[utility model content]
In order to overcome the shortcomings of existing technology, the utility model provides a kind of rotary self-locking bolt, its own is passed through
Fixed body is not influenced by fixed body autologous density, without generating pretightning force between tube expansion and fixed body, is obstructed by rotary screw
Band clamping fixed body, it is easy to operate not easily to fall off.
The technical scheme adopted by the utility model is a kind of rotary self-locking bolt, casing is hollow to be equipped with screw hole, spiral shell
Bar matches with screw hole, and sleeve edge is equipped with fricting strip, obstructs made of the multiple strip slot intervals of casing other side integrally connected
Band, barrier tape connector sleeve point, set point are equipped with screw hole to casing side.
Preferably, a kind of rotary self-locking bolt, casing, fricting strip, barrier tape and set point be metal or
Person's plastics.
Preferably, a kind of rotary self-locking bolt, fricting strip uniformly increases from casing one end to sharp side is covered
Increase to middle part at high or both ends.
The utility model is the utility model has the advantages that drive barrier tape rotation, formation pretightning force, behaviour by rotary screw using the present apparatus
Make simple.
To make the feature for being further understood that the utility model and technology contents, it is detailed in the utility model attached drawing and embodiment party
Formula, however institute's accompanying drawings it is only for reference with illustrate to use, be not to be limited to the utility model.
[Detailed description of the invention]
Fig. 1 is the utility model structure chart；
Fig. 2 is the utility model use state diagram；
1- screw rod in figure；2- casing；3- set point；4- fricting strip；5- screw hole；6- strip slot interval；7- barrier tape.
[specific embodiment]
The utility model is described further with reference to the accompanying drawings and examples:
Embodiment 1, a kind of rotary self-locking bolt, casing is hollow to be equipped with screw hole, and screw rod matches with screw hole, covers tube edge
Edge is equipped with fricting strip, barrier tape made of the multiple strip slot intervals of casing other side integrally connected, barrier tape connector sleeve point, set point
Screw hole is equipped with to casing side.
Embodiment 2, a kind of rotary self-locking bolt, casing is hollow to be equipped with screw hole, and screw rod matches with screw hole, covers tube edge
Edge is equipped with fricting strip, barrier tape made of the multiple strip slot intervals of casing other side integrally connected, barrier tape connector sleeve point, set point
It is equipped with screw hole to casing side, casing, fricting strip, barrier tape and set point are metal or plastics.
Embodiment 3, a kind of rotary self-locking bolt, casing is hollow to be equipped with screw hole, and screw rod matches with screw hole, covers tube edge
Edge is equipped with fricting strip, barrier tape made of the multiple strip slot intervals of casing other side integrally connected, barrier tape connector sleeve point, set point
Screw hole is equipped with to casing side.Its fricting strip uniformly increases from casing one end to sharp side is covered.
Embodiment 4, a kind of rotary self-locking bolt, casing is hollow to be equipped with screw hole, and screw rod matches with screw hole, covers tube edge
Edge is equipped with fricting strip, barrier tape made of the multiple strip slot intervals of casing other side integrally connected, barrier tape connector sleeve point, set point
Screw hole is equipped with to casing side.Increase to middle part at its fricting strip both ends.
The present apparatus use of time, runs through fixed body using boring device, and casing is embedded in aperture, four wall friction item of casing with
Pretightning force is formed between fixed body, is inserted in fixed body using screw rod, and rotary screw is until screw tip is rotated to set point, rotation
Screw rod drives set point rotation, covers point rotation and drives connection barrier tape rotation in conjunction, barrier tape one end is fixed with casing, relatively
The barrier tape of rotation drives set point rotation in screw rod, and set point is moved to fixed body, barrier tape rotation twist, until set point compresses resistance
Pretightning force is formed between band and fixed body.
Barrier tape rotation is driven by rotary screw using the present apparatus, forms pretightning force, it is easy to operate.
However the above-mentioned preferably feasible embodiment of only the utility model, non-therefore limitation the utility model protect model
It encloses, according to the made various modifications of above-described embodiment or applies within this technical solution protection scope.
