Abstract
A kind of fastener is the utility model is related to, more particularly to a kind of reinforced clamping screw.The utility model provides following technical scheme：A kind of reinforced clamping screw, the screw thread body of rod for including cap body and being connected with cap body, cap body relative to be connected with the screw thread body of rod offered at the other end of one end it is some along cap body and the screw thread body of rod axial direction reinforced holes, the bracing piece being adapted to reinforced hole is inserted with each reinforced hole respectively, support member is provided between bracing piece and the inwall of reinforced hole, and expanding foam solution is filled between the gap of each support member.Using above-mentioned technical proposal, there is provided it is a kind of be unlikely to deform, reinforced clamping screw simple in construction.
Description
Technical field
A kind of fastener is the utility model is related to, more particularly to a kind of reinforced clamping screw.
Background technology
Clamping screw is a kind of fastener, and it can be supported the use with nut.Traditional clamping screw mainly by screw rod and with
The nut composition of linking, for the less bolt of diameter, there is foreign matter in using extruding or hole of the process by external force
When it is yielding, its stress intensity is small.
The content of the invention
In view of the deficienciess of the prior art, the utility model provides and a kind of be unlikely to deform, be simple in construction reinforced
Clamping screw.
To achieve the above object, the utility model provides following technical scheme：A kind of reinforced clamping screw, includes
Cap body and the screw thread body of rod being connected with cap body, it is characterised in that：Described cap body is connected the another of one end relative to the screw thread body of rod
End offers some reinforced holes axial along cap body and the screw thread body of rod, is inserted with each reinforced hole and is adapted to reinforced hole respectively
Bracing piece, support member is provided between bracing piece and the inwall of reinforced hole, and expanding foam solution is filled between the gap of each support member.
Using above-mentioned technical proposal, by setting reinforced hole in cap body and the screw thread body of rod, and set in reinforced hole
Bracing piece, make that not only there is more preferable connecting between cap body and the screw thread body of rod, while the screw thread body of rod is strengthened by foreign object
Stress intensity, the situation that will not be deformed or bend in use, the setting of expanding foam solution can promote bracing piece will not be by
Come off in reinforced hole.
The utility model is further arranged to：Bracing piece is column, and support member, which includes, to be distributed on bracing piece side face
Boss and on reinforced hole inwall and between each boss clearance fit extension projection.
Wherein, boss and extension projection are respectively cross section in fan-shaped blocks.
Using above-mentioned technical proposal, such setting structure is simple, easy to process, and compactedness is good, stability under loading.
The utility model is further arranged to：Cap body and the joining place of the screw thread body of rod have annular recess, and the ring-type is recessed
There is nickel dam on groove inwall.
Using above-mentioned technical proposal, the stress that can reduce the screw thread body of rod is so set, prevents the screw thread body of rod from deforming.
The utility model is further described below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment；
Fig. 2 is Fig. 1 A-A diagrammatic cross-sections.
Embodiment
A kind of reinforced clamping screw as shown in Figure 1 and Figure 2, include cap body 1 and the screw thread body of rod being connected with cap body 1
2, cap body 1 relative to be connected with the screw thread body of rod 2 offered at the other end of one end it is some along cap body 1 and the axial direction of the screw thread body of rod 2
Reinforced hole 3, is inserted with the bracing piece 4 being adapted to reinforced hole 3 in each reinforced hole 3 respectively, the inwall of bracing piece 4 and reinforced hole 3 it
Between be provided with support member 5, and expanding foam solution is filled between the gap of each support member 5.In such scheme, by cap body 1 and screw thread
Reinforced hole 3 is set on the body of rod 2, and bracing piece 4 is set in reinforced hole 3, makes not only to have between cap body 1 and the screw thread body of rod 2
More preferable connecting, while strengthen by foreign object the stress intensity of the screw thread body of rod 2, will not deform in use or
The situation of bending, the setting of expanding foam solution can promote bracing piece 4 will not be by being come off in reinforced hole 3.
In the utility model embodiment, bracing piece 4 is column, and support member 5, which includes, to be distributed on the side face of bracing piece 4
Boss 51 and on the inwall of reinforced hole 3 and between each boss 51 clearance fit extension projection 52.Certainly, it is necessary to
Illustrate, also can be by boss on the inwall of reinforced hole 3, and extension projection is arranged on the side face of bracing piece 4, and
Feasible.Boss 51 and extension projection 52 are respectively cross section in fan-shaped blocks.Or triangular shape or square certainly,
Shape, all it is feasible.
For the force stability of the further strengthened thread body of rod 2, prevent it from deforming in use.Cap body 1
There is annular recess 6 with the joining place of the screw thread body of rod 2, there is nickel dam 61 on the inwall of annular recess 6.
Claims (4)
