Abstract
The invention discloses a telescopic fastening bolt. The telescopic fastening bolt comprises a bolt body of which one end is provided with screw threads; the other end, opposite to the screw threads, of the bolt body is provided with a sliding chute; a cone is arranged inside the sliding chute; a telescopic rod is clamped at the outer side of the sliding chute; the tail end of the telescopic rod is in an oblique shape matched with the cone; a pre-tightening hole is formed in the center of the bolt body; the left end of the pre-tightening hole is close to the cone. According to the telescopic fastening bolt disclosed by the invention, the telescopic rod is pushed out by leftward movement of the cone inside the bolt body and is inserted into a wall body in order to prevent the bolt body from falling off and realize fastened installation.
Description
Technical field
The present invention relates to a kind of securing member, be specifically related to a kind of telescopic fastening bolt.
Background technology
In construction and decoration and mechanical erection field, commonly used to expansion bolt, but traditional expansion bolt,
Its structure is the conehead in screw rod one end with tension, and outer cover has the thin walled cylinder body of opening, installs
Shi Yaoxian is inserted in pre-drilled hole, by clamp sleeve after nut of screwing on, by the conehead on screw rod to
Outer movement, makes the opening of sleeve deform generation tension, and such structure the most often goes out
Existing tension force is inadequate, the situation of pretensioning effect difference, causes fastening effect poor, the caducous problem of bolt, and one
Secondary fastening nut is also not fully complete prefastened fixed pattern and needs secondary fastening nut, can cause bolt failure or scrap.
Summary of the invention
It is an object of the invention to: a kind of telescopic fastening bolt is provided, to solve the existence of conventional expanded bolt
Tension force inadequate, pretensioning effect is poor, the problem of inefficacy easy to fall off.
It is an object of the invention to realize by following technical solution:
A kind of telescopic fastening bolt, sets threaded bolt body including one end, on described bolt body with
The other end that screw thread is relative has chute, is provided with cone in chute, is installed with expansion link outside chute, flexible
Bar end is match with cone skewed, and bolt body center has pre-tieholen, this pre-tieholen left end with
Cone is adjacent.
Stopper slot is had, this stopper slot geomery and expansion link ends match in described cone.
Described expansion link end is provided with limited block.
Described expansion link has four.
The invention has the beneficial effects as follows:
Compared with prior art, the telescopic fastening bolt that the present invention provides, by the cone within bolt body
Body moves to left and is ejected by expansion link and insert it in body of wall, can prevent coming off of bolt body, it is achieved fastening
Install；And it being provided with stopper slot at cone outer wall, this stopper slot locks mutually with expansion link, prevents cone from moving
While be avoided that expansion link is to contract so that it is persistently maintain support effect, improve slip-off preventing further
Performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
In figure: 1-bolt body, the pre-tieholen of 2-, 3-cone, 4-barb, 5-chute, 6-nut, 7-packing ring,
8-body of wall, 9-stopper slot.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme is described further, but required protection domain is also
It is not limited to described；
As it is shown in figure 1, the telescopic fastening bolt that the present invention provides, set threaded bolt body including one end
1, on described bolt body 1, the other end relative with screw thread has chute 5, is provided with cone 3, chute in chute 5
Being installed with expansion link 4 outside 5, expansion link 4 end is skewed with what cone 3 matched, bolt body 1 center
Having pre-tieholen 2, this pre-tieholen 2 left end is adjacent with cone 3.
In order to prevent cone 3 to be subjected to displacement so that expansion link resilience, described cone 3 has stopper slot 9, should
Stopper slot 9 geomery and expansion link 4 ends match.
In order to prevent expansion link 4 from coming off from bolt body 1, described expansion link 4 end is provided with limited block 10.
In order to strengthen fastening effect, described expansion link 4 has four.
During use, first bolt body 1 is inserted and be opened in the installing hole on body of wall 8, then packing ring 7 is socketed
On bolt body 1, then nut 6 is tightened on the thread segment on bolt body 1, then in pre-tieholen 2
Placing a cement nail, ailhead is internal towards body of wall 8, taps cement nail and makes it move to left and contact with cone 3,
Continuing to tap cement nail, cement nail drives cone 3 to translate to body of wall 8 depths, along with the movement of cone 3, flexible
Bar 4 is displaced outwardly, and when expansion link 4 end snaps in the stopper slot 9 in cone 3, expansion link 4 is real with cone 3
Lock the most mutually, prevent cone 3 from moving to right and preventing expansion link 4 resilience, tightening nut 6 again, i.e. complete this
The installation of invention and fixing.
