Description
[technical field]
The utility model relates to the technical field of expansion bolt, the technology of especially a kind of dropproof expansion bolt of pattern pressing type
Field.
[background technique]
Expansion bolt is usually to be made of components such as screw rod cylinder, expansion-head, expansion sleeve, nut, washer and gaskets,
Nut external and the built-in expansion bolt of nut can be divided into according to the location of nut.Nut external expansion bolt refers to
Nut is exposed to the form of outside, and turning nut fastens expansion bolt；The built-in expansion bolt of nut refers to that nut (expands
Head) it is buried enter the connectors such as wall or concrete interior form of getting into the cave, the screw head for turning screw rod cylindrical end portions makes expansion bolt
Fastening.
Current expansion bolt is got into the cave to bore during the installation process and can not be bored deeply shallowly, once it bores deeply, in nut
For setting formula expansion bolt, it is easy to fall nut (i.e. expansion-head) in getting into the cave, especially when screw rod cylinder is screwed into again
It can be easier to occur, to put to no little inconvenience, and when turning, bolt (screw rod cylinder) and nut are easy to rotate together hair
The phenomenon that life cannot fasten influences the use of expansion bolt.In addition, if the material of ground or wall is than more loose or beat
The bit diameter in hole is bigger than normal, causes to form clearance fit between preset holes and expansion sleeve, during tightening screw rod, occurs
The problem of transfer that casing is rotated with bolt rotation, built on the sand so as to cause device installation.
[utility model content]
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of dropproof expanding screw of pattern pressing type
Bolt, sleeve body are hexagonal cylindricality and top with embossing, after being inserted into preset holes can effective rotation stop, avoid and expansion nut one
It rises as bolt rotates in hole, ensure that the tightness of expansion bolt, by the way that several second grooves are arranged on card, make
Card can fix the expansion nut of different height after bending, the spreading of adjustable casing while avoiding expansion nut from falling
Degree.
To achieve the above object, the utility model proposes a kind of dropproof expansion bolts of pattern pressing type, including bolt, set
Pipe, gasket, spring washer and expansion nut, described sleeve pipe include that center is equipped with the sleeve body of through-hole and is located at sleeve body bottom
Several cards in portion, the top of described sleeve pipe ontology are equipped with embossing, and the outer wall of described sleeve pipe ontology is equipped with several therefrom
Centre extends to the first groove through tube wall of bottom end, and the expansion nut is truncated cone-shaped and center is equipped with threaded hole, the card
Piece is inclined at the bottom of sleeve body and forms a flaring, and the tilt angle and expansion nut of the card are adapted,
Inner wall of the card close to bottom end is equipped with several second grooves and can bend inwards to form a sky along the second groove
For chamber to which expansion nut is fixed on inside, the bolt includes hexagonal screw head and with externally threaded screw rod, the screw rod from
Spring washer, gasket, casing and expansion nut are sequentially passed through under.
Preferably, described sleeve pipe ontology and card are structure as a whole.
Preferably, described sleeve pipe ontology is hexagonal cylindricality.
Preferably, the embossing is twill embossing or straight grain embossing, the length of the embossing is sleeve body length
1/4~1/3.
Preferably, the quantity at least two of second groove and by card along lowermost end the second groove to
Card bottom end spacing is greater than the diameter of screw rod after inner bending.
Preferably, the card and the first groove are distributed along the axis misalignment of casing.
The utility model has the beneficial effects that the sleeve body of the utility model is hexagonal cylindricality and top has embossing, when
Be inserted into preset holes after can effective rotation stop, avoid rotating in hole together with expansion nut with bolt, ensure that expansion bolt
Tightness makes card that can fix the expansion nut of different height after bending by the way that several second grooves are arranged on card,
The spreading degree of adjustable casing while avoiding expansion nut from falling.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
