Abstract
The utility model discloses a composite bolt which comprises a metal bolt body and a twist off type fastening head made of plastics. The metal bolt body comprises a screw rod and a hexagonal stressed part, wherein an external thread is placed on the screw rod, and the hexagonal stressed part is arranged at a side end of the screw rod. The twist off type fastening head comprises a linkage part, a hexagonal twisting part and a twist off part, wherein the linage part is provided with a containing cavity, the twist off part is connected with the hexagonal twisting part and the linkage part, and the external diameter of the twist off part is smaller than that of the linkage part and the hexagonal twisting part. The linkage part is fixed on the hexagonal stressed part on the metal bolt body in an injection molding, or the linkage part is directly connected on the hexagonal stressed part on the metal bolt body in a sleeved mode, and the hexagonal stressed part is placed inside the containing cavity of the of the linkage part of the twist off type fastening head. The composite bolt is high in production efficiency and capable of effectively reducing 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 lower-cost composite bolt.
The technological scheme that realizes the utility model purpose is: a kind of composite bolt, comprise the twisted off type fastener head that metal bolts body and plastics are made, and this metal bolts 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; This 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; The hexagonal force part is in the holding cavity of twisted off type fastener head joint part.
In the technique scheme, joint part also forms one by injection molding and is positioned at the hexagonal forced section is twisted section's one side away from hexagonal plastic washer.
The moment mechanism of the utility model by adopting plastics to make composite bolt can obtain and tradition adopts the same technique effect of metal moment bolt, and the manufacturing process comparative maturity, and manufacturing efficiency is higher, effectively reduces manufacture cost.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
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.
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.
Can draw from present embodiment, the moment mechanism of the utility model by adopting plastics to make composite bolt can obtain and tradition adopts the same technique effect of metal moment bolt, and the manufacturing process comparative maturity, manufacturing efficiency is higher, thereby can effectively reduce 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.
