Abstract
A kind of U-shaped expansion hook hitch, including U bolt (1), nut (2), expansion sleeve (3) and conic (4), U bolt (1) bipod has screw thread (5), nut (2) is cased on screw thread (5), the end of screw thread is connected with conic (4)；Two expansion sleeves (3) are inserted in respectively in U bolt (1) bipod.The drawbacks of it is U-loop that U bolt (1) both ends, which are among screw thread (5), and the one-piece type connection of ring, bolt increases overall construction intensity, and there is no axial-rotations, cannot directly remove and can play the role of anti-loose, tamper.The bolt at both ends is anchored at one entirety of formation in concrete or wall simultaneously, increases radial shearing force and the stability by impact force and when shaking.
Description
Technical field
The utility model is related to the pin being anchored in wall or similarity piece combined with expansion set or other devices, by by its
It is inserted into fastening, espespecially a kind of U-shaped expansion hook hitch in the cinclides made thus.
Background technology
The U-shaped expansion hook hitch of the prior art is made of U-shaped ring 21, connection sheet 23 and expansion bolt 22 as shown in Figure 2, U-shaped
Ring 21 is connect with connection sheet 23, and connection sheet 23 is connect with two expansion bolts 22, and this structure can not bear larger radial shear
Power, safety coefficient is relatively low when being given a shock or impacting, this is its disadvantage.
Invention content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of U-shaped expansion hook hitchs.It is intended to improve U
Shape expansion hook hitch bears the intensity of radial shear power, improves safety coefficient.
Technical solution adopted by the utility model to solve its technical problems is：A kind of U-shaped expansion hook hitch, including U are provided
Shape bolt, nut, expansion sleeve and conic, the U bolt bipod have screw thread, nut are cased on screw thread, screw thread
End is connected with conic；Two expansion sleeves are inserted in respectively in U bolt bipod.
When the rotation of the nut on both sides pushes out expansion tube, expansion tube laterally expands under the taper effect of conic
, to be anchored in the concrete top having openning hole in advance or wall outer side face, U-bolt can not be rotated and be moved after installation is complete
Dynamic, U-bolt is still anchored in concrete or wall after even unclamping hex nut.
The utility model has the beneficial effects that：The intensity that U-shaped expansion hook hitch bears radial shear power is improved, safety system is improved
Number.
Description of the drawings
The utility model will be further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the U-shaped expansion hook hitch structural schematic diagram of the prior art.
In figure：1 it is U bolt, 2 be nut, 3 be expansion sleeve, 4 be conic, 5 is screw thread；
21 be U-shaped ring, 22 be expansion bolt, 23 is connection sheet.
Specific implementation mode
Referring to attached drawing, a kind of U-shaped expansion hook hitch of the utility model, it is characterised in that：Including U bolt 1, nut 2, expansion
Casing 3 and conic 4,1 bipod of the U bolt have screw thread 5, and nut 2 is cased on screw thread 5, and the end of screw thread is connected with
Conic 4；Two expansion sleeves 3 are inserted in respectively in 1 bipod of U bolt.
It is U-loop that 1 both ends of U bolt, which are among screw thread, and the one-piece type connection of ring, bolt increases overall construction intensity, and
The drawbacks of there is no axial-rotations cannot directly remove and can play the role of anti-loose, tamper.The bolt at both ends is anchored at simultaneously
An entirety is formed in concrete or wall, increases radial shearing force and the stability by impact force and when shaking.
