Abstract
The utility model discloses a bolt equipped with a washer, the bolt comprises a bolt body and a soft washer; the bolt body consists of a bolt head and a screw, the bolt head is fixedly connected at one end of the screw; the washer is sleeved at the connection part of the bolt head and the screw, the washer and the bolt body are connected into one piece. The soft washer is integrated into one-piece with the bolt body in the utility model, the washer takes an isolation effect between the bolt head and the surface of the object to be fastened, preventing the surface of the object to be fastened from being damaged because of repeated locking with bolts.
Description
Technical field
The utility model relates to a kind of machanical fastener, relates in particular to a kind of screw with pad.
Background technique
At present, the part of a lot of household appliances all is to adopt metallic screw to connect, the front and rear casing of household electrical appliances for example, and these parts relate to the outward appearance of product, and are very high to surperficial quality requirement, generally all done and sprayed paint or other process of surface treatment.Portioned product before dispatching from the factory often for some reason barrier need repeatedly take housing apart and keep in repair, again housing is locked up again.Existing metallic screw is not provided with the spacer of the fastened body surface of protection; the harder metallic screw head of material directly contacts with part surface; repeatedly lock surface quality of workpieces is damaged, thereby influenced the outward appearance of product, cause damage for each production firm.If when locking part at every turn, all lock the position softer spacer of increase material and protect part surface at screw, can increase production process again and manufacture a finished product, bring inconvenience to production.
The model utility content
The utility model embodiment provides a kind of screw with pad, and the pad and the screw of softwood matter is integrated, has solved fastened thing surface quality and has repeatedly locked the problem that is damaged because of screw.
The utility model embodiment provides a kind of screw with pad, comprises the pad of screw body and softwood matter; Described screw body is made up of screw head and screw rod, and screw head is fixedly connected on an end of screw rod; Described pad is socketed in the joint of described screw head and described screw rod, and described pad and described screw body connect as one.
Further, also be provided with screw thread on the described screw rod, described plastic cement pad is between described screw head and described screw thread.
Implement the utility model, have following beneficial effect:
The screw of the band pad that the utility model embodiment provides, the pad of a softwood matter of socket between screw head and screw thread, and pad and screw is integrated.In the using process of screw, the pad of softwood matter plays the insulation blocking effect between screw head and the fastened thing surface, has avoided fastened thing surface quality to be damaged because of screw repeatedly locks.
Description of drawings
Fig. 1 is an embodiment's the structural representation of the screw of the band pad that provides of the utility model;
Fig. 2 is the structural representation of the screw body that provides of the utility model;
Fig. 3 is the structural representation of the pad that provides of the utility model.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described.
Referring to Fig. 1, be an embodiment's the structural representation of the screw of the band pad that provides of the utility model, described screw comprises the pad of screw body and softwood matter.
As shown in Figure 1, screw body is made up of screw head 1 and screw rod 2, and screw head 1 is fixedly connected on an end of screw rod 2; The pad 3 of softwood matter is socketed in the joint of screw head 1 and screw rod 2, and pad 3 connects as one with screw body.Further, also be provided with screw thread on the screw rod 2, pad 3 is specifically between screw head 1 and screw thread.
Wherein, described pad 3 is made by the material of softwood matter, and the hardness of pad 3 is damaged to avoid fastened thing surface quality less than the hardness on fastened thing surface.Preferably, the utility model can adopt the pad that materials such as plastic cement, leather, fiber are made.
In the screw using process; the pad 3 of softwood matter plays the insulation blocking effect between fastened thing surface and the screw head; avoided the metallic screw head of hard material directly to contact, overcome fastened thing surface quality and repeatedly locked the problem that is damaged because of metallic screw with fastened thing surface.
During concrete enforcement; described pad 3 can be designed to ring washer, the equal diameters of the internal diameter of packing ring and the screw rod of joint 2, and the external diameter of packing ring is more than or equal to the diameter of screw head 1; the assurance packing ring can be isolated metallic screw head and fastened thing surface fully, protects the surface quality of fastened thing.
The screw of the band pad that the utility model provides, an end attachment screw head 1 of screw rod 2, its other end (promptly relative with screw head 1 the other end) is conehead structure or tack structure.Further, screw rod 2 can also be designed to round column structure, is socketed with nut on it.The screw that the utility model provides may be used on tapping screw, machine screw and other the screw that is used for locking product parts, can avoid the product parts surface quality to be damaged because of screw repeatedly locks.
Referring to Fig. 2, be the structural representation of the screw body that provides of the utility model; Referring to Fig. 3, be the structural representation of the pad that provides of the utility model.
The screw that the utility model provides in process of production, behind the good head dummy of screw body pier shown in Figure 2, the pad with softwood matter shown in Figure 3 penetrates in the screw rod again, and pad and screw body are connected as one, carry out threading at last, so just made the screw of band pad shown in Figure 1.The utility model embodiment carries out threading after pad penetrated screw rod again, guarantees that pad holding firmly between screw head and screw thread, connects as one pad and screw.
Optionally, can more firmly connect as one with screw in order to make pad, the utility model can also use bonding Ji or by other treatment process with spacers on screw; Perhaps suitable groove is set, makes the pad holding in groove, thereby pad and screw are firmly connected as one in (the specifically position between screw head and screw thread) on the screw rod.
The screw of the band pad that the utility model embodiment provides, the pad of a softwood matter of socket between screw head and screw thread, and pad and screw is integrated.In the using process of screw, the pad of softwood matter plays the insulation blocking effect between screw head and the fastened thing surface, has avoided fastened thing surface quality to be damaged because of screw repeatedly locks.
The above is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
