Abstract
The utility model relates to a screw-type installed clamping nail which comprises a head part and a tail part. The head part is provided with a clamping buckle structure, and the tail part is matched with an installing column head; the tail part comprises two opposite protruding structures, each protruding structure comprises a smooth curved surface segment, the two protruding structures are opposite end to end so as to form a screw shape, and a gap is arranged between the two protruding structures. As the screw-type clamping buckle protruding structure of the clamping nail can be installed by adopting the self-tapping method, a matching clamping buckle thread can be formed on a plastic piece without the thread. By adopting the above matching, the clamping nail can be more firmly and tightly installed on the column head plastic piece, so as to ensure firm installation of the clamping nail, and avoid the easily-incurred loosening as well as shedding of the clamping nail due to fatigue utilization.
Description
Technical field
The utility model relates to a kind of bail structure, particularly relates to a kind ofly being applicable to that being installed in immovable point is spiral installation bail on the column cap form working of plastics.
Background technique
Common metal bail links to each other with the attachment hole that matches by head 10, usually adopt the mode that directly advances to install, as shown in Figure 1, the multi-disc raised structures are adopted in general metal bail bottom 20, utilization be that interference fit between raised structures and the working of plastics column cap realizes fixing of bail.In the process that advances, bail can destroy the working of plastics column cap, and therefore under bigger withdrawal force effect, bail can be deviate from from the working of plastics column cap.And because the working of plastics column cap is worn and torn by the bail scraping, under certain tired service condition, bail can become flexible, and radially can rock, and finally causes bail and column cap to get loose.Therefore, the project organization of this bail need improve.
The model utility content
The purpose of this utility model is, overcomes the defective of above-mentioned prior art and a kind of spiral installation bail that can improve bail and working of plastics connection reliability and can improve the installation reliability of final working of plastics is provided.
For achieving the above object, the utility model is taked following design proposal:
A kind of spiral installation bail, comprise head that is provided with buckle structure and the afterbody that matches with the installation column cap, described afterbody comprises two relative raised structures, each sheet in described two raised structures all comprises a level and smooth curved sections, two raised structures head and the tail form helical relatively, and are provided with the space between described two raised structures.
Preferably, the size in described space is less than the external diameter of described installation column cap.Described space is of a size of 6-6.5mm.
Preferably, described installation column cap is the working of plastics column cap.Described installation bail is made by metallic material.
The utility model has the advantages that:, thereby do not having to form cooperation buckle screw thread on the threaded plastic part because the spiral helicine snap projection structure of the utility model can adopt the mode of self tapping to install.This kind cooperation can guarantee that the installation of bail is firm with more firm the snugly fitting on the column cap working of plastics of bail, has also avoided the loosening and phenomenon that gets loose of bail that is easy to generate under tired service condition simultaneously.

Fig. 2 is a structural representation of the present utility model;
Fig. 3 installs preceding schematic representation for the utility model;
Fig. 4 is the schematic representation of the utility model after installing;
Longitudinal section sectional view after Fig. 5 the utility model is installed.
Embodiment
Referring to Fig. 2～Fig. 5, the preferred embodiment of a kind of spiral installation bail of the utility model shown in it, comprise head 1 that is provided with buckle structure and the afterbody 2 that matches with installation column cap 5, comprise two relative raised structures 3 at the afterbody described in the utility model 2, each sheet in described two raised structures 3 all comprises a level and smooth curved sections, as shown in Figure 2, described curved sections is preferably not one section helix structure at grade, and its thickness reduces on the direction of extending to afterbody 2 centers gradually, make two raised structures, 3 head and the tail form helical relatively, and be provided with space 4 between described two raised structures 3, just formed a spiral helicine sharpener buckle structure thus, and preferably, the size in described space 4 is less than the external diameter of described installation column cap, and described in the present embodiment space 4 is of a size of 6-6.5mm, described installation column cap is the working of plastics column cap, and its external diameter is of a size of 7-7.3mm, therefore, being preferably the installation bail that metallic material makes can adopt the mode of self tapping will not have the installation column cap 5 working of plastics column caps of screw thread to screw fixing from the periphery buckle in the process of installing.
When mounted, only need fixed installation column cap 5 working of plasticss on frock clamping, bail is screwed on the working of plastics column cap get final product.Usually use the special device of related domain to finish.
Referring to Fig. 5, the cross section after bail shown in it is installed, as can be seen from Figure 5 by spiral installation, being installed in that bail will be more firm installed on the column cap working of plastics, thereby, guarantee that finally the installation of working of plastics is firm.
Obviously, those of ordinary skill in the art can constitute various types of bail structures with a kind of spiral installation bail of the present utility model.
The foregoing description is only for the usefulness that the utility model is described; and be not to be to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the utility model scope; can also make various variations and modification; therefore all technological schemes that are equal to also should belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
