Abstract
The utility model relates to a screw connecting piece comprising arc teeth. The cross section of the arc teeth is in an arc shape, and the arc teeth form a screw of the connecting piece. The screw connecting piece can be screwed in an embedded preform with a nut by the arc teeth and can lift the preform. The spacing of screw pitch of the screw formed by the arc teeth is large so as to be beneficial to screwing.
Description
Technical field
The utility model relates to a kind of supplementary equipment for building, is specifically related to a kind of screw mandrel link.
Background technique
Rapid development along with China's economy; Building Trade in China was flourish in recent years; The production of supplementary equipment for building and manufacturing have obtained great achievement, but China does not also form certain codes and standards at the design field of building auxiliary equipment at present, and some supplementary equipment is not also produced in batches; The screw mandrel link that is used to connect fails to see on market because its lines that twines silk is special.
Summary of the invention
The utility model has overcome the deficiency of existing technology, has proposed a kind of screw mandrel link, and said link is provided with the circular arc tooth, can be tightened on securely on the corresponding nut, is beneficial to lifting and application.Said screw mandrel link can be met the need of market.
The technological scheme of the utility model is: a kind of screw mandrel link, comprise the circular arc tooth, and the cross section of said circular arc tooth is circular-arc, and said circular arc tooth constitutes the screw of said link.
Said screw mandrel link comprises screw mandrel cap and screw mandrel rear end.
Said screw mandrel link comprises the screw mandrel head.
The utlity model has following beneficial effect:
1) the utility model can have in the embedded prefabricated component of nut through being tightened on of circular arc tooth, can sling to prefabricated component.
2) the pitch spacing of the screw that is made up of the circular arc tooth of the utility model is big, helps screwing.
3) the utility model is tightened in the prefabricated component through the circular arc tooth, and circular arc tooth silk strength is strong, solid and reliable, can satisfy the demand in market.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the utility model structural representation that has the screw mandrel cap.
Fig. 2 is not for the utility model structural representation of screw mandrel cap.
Fig. 3 is that the utility model combines to use schematic representation with nut shape support.
Among the figure, 1, the screw mandrel cap; 2, screw mandrel rear end; 3, circular arc tooth; 4, screw mandrel head; 5, steel wire twines nut; 6, nut shape support.
Embodiment:
Referring to shown in Figure 1, the utility model comprises circular arc tooth 3, and the cross section of said circular arc tooth 3 is circular-arc, and said circular arc tooth 3 constitutes the screw of the utility model.The utility model has a lot of mutation; Can comprise screw mandrel cap 1 and screw mandrel rear end 2; Screw mandrel rear end 2 forms an integral body with the screw that is made up of circular arc tooth 3, and the utility model also can comprise screw mandrel head 4, and Fig. 1 is exactly the situation that has screw mandrel cap 1, screw mandrel rear end 2, circular arc tooth 3 and screw mandrel head 4.
Referring to shown in Figure 2, the utility model comprises circular arc tooth 3.Be applied in the situation that nut all need be screwed in two ends this moment.
Referring to shown in Figure 3; The utility model can be used in combination with other firmwares, and in this example, the utility model and nut shape support 6 are used; Nut shape support 6 is provided with steel wire and twines nut 5; The screw thread that steel wire twines nut 5 also is a circular arc, and therefore, the screw that circular arc tooth 3 constitutes can be screwed on the nut shape support 6.After nut shape support 6 was embedded in the precoated plate, through the circular arc tooth 3 of the utility model, the nut shape support 6 of screwing was accomplished lifting or other actions to prefabricated component.
The screw of the utility model is made up of the circular arc tooth, and the pitch spacing of screw is big, helps screwing, and solid and reliable, strength is strong, can meet the need of market.
