Abstract
A strengthened expansion nail comprises a body with a deep hole at the center. A plurality of convex fins are disposed on the outer wall of the middle of the body so as to form a supporting deforming structure, and an axial breakage groove is disposed in the middle of the tail end of the main body so as to form an outwards expanding and splitting structure. The strengthened expansion nail is reasonable in structure, after the body is punched into pre-drilled holes of a wall, the convex fins are squeezed by the hole wall to deform and can be supported in the holes quite reliably, simultaneously the tail ends of the convex fins can be expanded outwards and split to deform when squeezed by screws screwed in the convex fins, connection strength between the strengthened expansion nail and a wall is extremely high, and accordingly the strengthened expansion nail can bear extremely large force and meet special installation requirements.
Description
Technical field: the utility model relates to a kind of expandable nail that is used for fixing attachment screw.
Background technique: generally on wall, during fastening piece such as mounting screw, all need to install earlier the tie point of expandable nail as screw.Common expandable nail all is that plastics are made, and only is provided with hangnail at outer wall, and join strength is not very high, requires bigger place for some join strengths, is not suitable for using.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of join strength big reinforced expandable nail.
The utility model comprises that the center is provided with the main body of deep hole, is provided with some evagination fins at the middle part of main body outer wall and constitutes the supporting deformation structure, then is provided with axial breaking groove in the middle of the end of main body and constitutes outer expansion fork structure.
Of the present utility model rational in infrastructure, after main body is driven into the wall pre-drilled, each evagination fin is subjected to the extrusion-deformation of hole wall, can be supported on very reliably in the hole, terminal simultaneously expansion fork distortion outside the meeting under the screw extruding that is screwed into, the intensity that is connected with wall is very big, can bear very high dynamics, satisfies the special mounting requirement.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is embodiment's a main structure schematic representation.
Fig. 2 is the left view of Fig. 1.
SpecificallyMode of execution: as shown in the figure, main body 1 center is provided with deep hole 2, is provided with some evagination fins 3 at the middle part of main body 1 outer wall and constitutes the supporting deformation structure, and the terminal middle axial breaking groove 4 that then is provided with of main body 1 constitutes outer expansion fork structure.During use, earlier main body 1 is squeezed in the pre-drilled of wall, be screwed into screw from deep hole 2 again, each evagination fin 3 extrusion of main body 1, firmly be supported in the pre-drilled, the end of main body 1 can be out of shape by expansion fork outside breaking groove 4 under the screw extruding that is screwed into simultaneously, and the intensity that is connected with wall is very big, can bear very high dynamics.
Each the evagination fin 3 of present embodiment and the middle part outer wall of main body 1 structure that is formed in one, rational in infrastructure, convenient for production.The end of main body 1 is the ladder cone table shape, and the external wall of upper portion of main body 1 then is provided with barb 5, can further strengthen like this supporting in squeezing into wall hole.In fact, for the thin partition wall of wall thickness, pre-drilled can be penetrated, main body 1 penetrates the back under the screw-driving extruding, end expansion fork outside breaking groove 4, and each evagination fin 3 is because through the wall rear, can be out of shape more that evagination is buckled in the wall rear, can fix equally, application area is wider.
Claims (3)
1. reinforced expandable nail, comprise that the center is provided with the main body of deep hole, it is characterized by: the middle part outer wall in main body (1) is provided with some evagination fins (3) formation supporting deformation structure, and the terminal middle axial breaking groove (4) that then is provided with of main body (1) constitutes outer expansion fork structure.
2. reinforced expandable nail according to claim 1 is characterized by: the middle part outer wall of each evagination fin (3) and main body (1) structure that is formed in one.
