Description
Technical field
The utility model is related to a kind of screw location structure, particularly a kind of perforation screw with sleeve pipe.
Background technology
Setscrew is a kind of common fastening assembly, and its building block includes screw, expansion sleeve and nut.It
Principle be to promote expansion sleeve to expand using wedge-shaped gradient, with hole wall be in close contact, so as to produce friction bond stress, reach
Fixed effect, is generally used for the fastening on the materials such as cement, brick such as guard rail, canopy, air-conditioning.
Existing setscrew exists below weak point：
When the 1st, installing, expansion sleeve is needed completely into wall (or sheet material), and drilling depth needs to be more than expansion sleeve
Length, it is just inapplicable under the relatively thin usage scenario of sheet material.
2nd, fixed effect is not very reliable, if load has significant shock, it may occur however that release.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of perforation screw with sleeve pipe.It
Solve the problem of existing setscrew is not suitable for compared with being installed on light sheet.
The technical solution of the utility model is：Perforation screw with sleeve pipe, including screw；Screw one end is ailhead, separately
One end is screw rod；It also includes sleeve pipe；Sleeve pipe rear end is provided with more pieces of resilient calvus, per a piece of elastic claw to the outside of sleeve pipe
Bending；Casing pipe sleeve is on screw, and the ailhead of its front end and screw is affixed, and its front end mouth of pipe is inserted in by screw rod one end of screw
Screw.
The further technical scheme of the utility model is：The ailhead of screw includes conical surface section and straight bar section；The two of conical surface section
End is connected with straight bar section and screw rod respectively.
Further technical scheme is the utility model：The conical surface section of sleeve pipe and screw ailhead, which is formed, to be interference fitted.
The utility model further technical scheme is：The maximum outside diameter of screw is located on ailhead, and the maximum of sleeve pipe is outer
Footpath is located on elastic claw；Maximum outside diameter of the sleeve pipe at elastic claw is more than maximum outside diameter of the screw at ailhead.
The utility model further technical scheme is：The screw rod of screw is provided with the plane clamped for spanner.
The utility model further technical scheme is：Elastic claw is integrally formed with sleeve pipe, and with the center of sleeve pipe
It is uniform in a ring centered on line.
The utility model further technical scheme is：It also includes nut and pad；The screw rod rotation of nut and screw
Match somebody with somebody, the screw rod of pad and screw is screwed and is located between nut and sleeve pipe.
The utility model has the following advantages that compared with prior art：
The screw location structure is applied to install on relatively thin sheet material or wall, can be on the screw rod of screw after installing
Other parts are connected, firm and reliable connection of the screw location structure with sheet material or between the walls is difficult to release.
The utility model is further described below in conjunction with figure and embodiment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is a view of the utility model when starting to install；
Fig. 3 is a view of the utility model in installation process；
Fig. 4 is view of the utility model in installation.
Embodiment
Embodiment 1：
As shown in figure 1, the perforation screw with sleeve pipe, including screw 1, sleeve pipe 2, nut 3 and pad 4.
The one end of screw 1 is ailhead, and the other end is screw rod 13.Ailhead includes conical surface section 11 and straight bar section 12, conical surface section 11
Two ends are connected with straight bar section 12 and screw rod 13 respectively.
The maximum outside diameter of screw 1 is located on the straight bar section 12 of ailhead, and the maximum outside diameter of sleeve pipe 2 is located on elastic claw 21.
Maximum outside diameter S of the sleeve pipe 2 at elastic claw 21 is more than maximum outside diameter Z of the screw 1 at ailhead.
The rear end of sleeve pipe 2 is provided with more pieces of resilient calvus 21 (being eight elastic claws in the present embodiment), per a piece of elastic claw
Piece 21 is to the outer lateral bend of sleeve pipe 2.Sleeve pipe 2 is sleeved on screw 1, and its front end mouth of pipe is covered by one end of screw rod 13 of screw 1
Enter screw 1, the conical surface section 11 of its front end and the ailhead of screw 1, which is formed, to be interference fitted, by the principle of conical surface self-locking reach it is locked (i.e.
It is affixed) effect.
The screw rod 13 of nut 3 and screw 1 is screwed.
The screw rod 13 of pad 4 and screw 1 is screwed and positioned between nut 3 and sleeve pipe 2.
It is preferred that, the screw rod 13 of screw 1 is provided with the plane 131 clamped for spanner.
It is preferred that, elastic claw 21 is integrally formed with sleeve pipe 2, and uniform in a ring centered on the center line L of sleeve pipe 2.Tool
Body says that sleeve pipe 2 is that one end is to be processed by sleeve pipe 2 in one end that caliber expand in tubaeform sleeve pipe, elastic claw 21 is extended out
Have formed by multiple breach 22, a piece of elastic claw 21 is formed between adjacent gap 22.
Summary is of the present utility model to be used：As in Figure 2-4, the first holes drilled through 51 on sheet material 5 (or wall), leads to before installing
The aperture in hole 51 should be less than maximum outside diameter S of the sleeve pipe 2 at elastic claw 21, and simultaneously greater than maximum of the screw 1 at ailhead is outer
Footpath Z.
During installation, the ailhead of screw 1 is introduced into through hole 51 (as shown in Figure 2), and sleeve pipe 2 is when by through hole 51, elastic claw
Piece 21 can shrink under the limitation of hole wall to the inner side of sleeve pipe 2, and when sleeve pipe 2 is completely by through hole 51, elastic claw 21 is in elastic force
Reinstatement (as shown in Figure 3) is strutted under effect immediately, the plane 131 on the screw rod 13 of screw 1 is now vised by spanner, is led to
Another spanner rotating nut 3 is crossed, screw 1 is locked on sheet material 5.In the state of complete locking, elastic claw 21 is complete
Open and be close on a side surface of sheet material 5 (as shown in Figure 4).
