Abstract
The utility model discloses a composite bolt which comprises a bolt body and a twisting-off type fastening head. The bolt body comprises a bolt rod with external threads and a hexagonal stress part arranged at one side end of the bolt rod. The twisting-off type fastening head comprises a connection part provided with a containing cavity, a hexagonal twisting part, and a twisting-off part connected with the hexagonal twisting part and the connection part. The outer diameter of the twisting-off part is smaller than that of the connection part and that of the hexagonal twisting part. The hexagonal stress part is located in the containing cavity of the connection part of the twisting-off type fastening head. The hexagonal twisting part of the twisting-off type fastening head is provided with a round adjusting hole which is arranged with the bolt rod concentrically. The bottom wall of the adjusting hole is arranged in the twisting-off part or the connection part of the twisting-off type fastening head. As adjusting holes of different sizes can be processed, the composite bolt simplifies procedures of manufacturing the composite bolt with different twisting moment, and effectively lowers manufacture cost.
Description
Technical field
The utility model belongs to the fastener constructions design field, is specifically related to a kind of composite bolt.
Background technique
Existing torque nut all is to adopt metallic material to make, and its cost is higher, and because the moment mechanism of twisting into two parts all is discard processing, has caused significant wastage.
The model utility content
The purpose of this utility model provides a kind of composite bolt that difference is twisted into two parts moment of being convenient to make.
The technological scheme that realizes the utility model purpose is: a kind of composite bolt, comprise bolt body and twisted off type fastener head, and this bolt body comprises the hexagonal forced section that is provided with externally threaded screw rod and is arranged on screw rod one side; This twisted off type fastener head comprises that the joint part, the hexagonal that are provided with holding cavity twist section and connect the section of twisting into two parts that hexagonal is twisted section and joint part, twists into two parts the external diameter of section and twists section less than joint and hexagonal; The hexagonal force part is in the holding cavity of twisted off type fastener head joint part; The hexagonal section of twisting of twisted off type fastener head is provided with the circular adjustment hole with the concentric setting of screw rod, and the diapire of this adjustment hole is arranged in the section of twisting into two parts or the joint part of twisted off type fastener head.
In the technique scheme, bolt body adopts metal to make, and the twisted off type fastener head adopts plastics to make.
In the technique scheme, joint part is fixed on by injection molding on the hexagonal forced section of metal bolts body, and perhaps this joint part directly is socketed on the hexagonal forced section of metal bolts body.
In the technique scheme, be equipped with in the adjustment hole be used to the anti-deforming cylinder that prevents twisted off type fastener head stress deformation when twisting.
The utility model is by arranging circular adjustment hole at the twisted off type fastener head, thereby can be by the adjustment holes of the different sizes of processing, simplifies to make and differently twists into two parts the composite bolt of moment, effectively reduces manufacture cost.

Embodiment
(embodiment 1)
Fig. 1 is a kind of structural representation of the utility model the first structure, has shown the first embodiment of the present utility model.
Present embodiment is a kind of composite bolt, comprises the twisted off type fastener head 2 that metal bolts body 1 and plastics are made, and this metal bolts body 1 comprises the hexagonal forced section 12 that is provided with externally threaded screw rod 11 and is arranged on screw rod 11 1 sides; This twisted off type fastener head 2 comprises that the joint part 21, the hexagonal that are provided with holding cavity twist section 22 and connect the section of twisting into two parts 23 that hexagonal is twisted section 22 and joint part 21, twists into two parts the external diameter of section 23 and twists section 22 less than joint and hexagonal; This joint part 21 is fixed on the hexagonal forced section 12 of metal bolts body 1 by injection molding, and hexagonal forced section 12 is arranged in the holding cavity of twisted off type fastener head 2 joint parts 21.
In the present embodiment, the hexagonal of twisted off type fastener head 2 is twisted section 22 and is provided with circular adjustment hole 221 with screw rod 11 concentric settings, and the diapire of this adjustment hole 221 is arranged in the section of twisting into two parts 23 or the joint part 21 of twisted off type fastener head 2.
Present embodiment is to make plastics twisted off type fastener head by injection molding, but in concrete practice, can make on its hexagonal forced section 12 that can directly be connected to metal bolts body 1 by changing the shape of holding cavity, also is feasible.
(embodiment 2)
Fig. 2 is a kind of structural representation of the utility model the second structure, has shown the second embodiment of the present utility model.
Present embodiment is substantially the same manner as Example 1, and difference is: be equipped with in the adjustment hole 221 be used to the anti-deforming cylinder 3 that prevents twisted off type fastener head 2 stress deformation when twisting.
Can draw from above-described embodiment 1 and embodiment 2, the utility model is by arranging circular adjustment hole at the twisted off type fastener head, thereby can be by the adjustment holes of the different sizes of processing, simplifies to make and differently twists into two parts the composite bolt of moment, effectively reduces manufacture cost.
Obviously, above-described embodiment of the present utility model only is for the utility model example clearly is described, and is not to be restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection domain of the present utility model.
