Abstract
The utility model discloses a vibration-damping screw nail, which belongs to a threaded connecting part and mainly resolves problems that the existing screw nail is easy to deform and drop in influence of external vibration. The vibration-damping screw nail comprises a nail head and a nail body, and the nail body is provided with thread. The vibration-damping screw nail is characterized in that the threaded outer surface of the nail body is tightly attached with a rubber layer, a rubber ring is disposed on a surface of the nail head which is connected with the nail body, and the nail body extends from a hollow portion of the rubber ring. The rubber layer and the rubber ring not only have a vibration-damping function, but also have a certain sealing function, enlarge friction force, and effectively reduce vibration influence to fixed screw nails. The vibration-damping screw nail is particularly adaptable to occasions with vibrating mechanical equipment and the like.
Description
Technical field
The utility model relates to a kind of threaded connector, specifically is a kind of damping screw that can prevent effectively that set screw from getting loose voluntarily under the influence of vibrations.
Background technique
Existing threaded connector all is to fix by self-locking, screw is widely used on various machinery, these equipment all can produce vibration in running, screw will get loose under the influence of vibrations voluntarily, if the staff can not check for the screw connection portion position and adjust timely, be easy to have an accident, people adopt various measures to prevent that screw from getting loose at present, but still screw itself is not improved, make it fundamentally avoid the phenomenon that gets loose voluntarily.
The model utility content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of damping screw, and this screw alleviates the influence of vibrations to set screw effectively.
The technological scheme that its technical problem that solves the utility model adopts is: this kind damping screw, comprise ailhead and nail body, and the nail body is provided with screw thread, it is characterized in that thread outer surface closely is pasted with a rubber layer on the described nail body; Described ailhead is provided with a rubber ring with the face that the nail body is connected, and the nail body stretches out from the hollow space of rubber ring.
The beneficial effects of the utility model are: simple in structure, cost is low, is provided with the effect that rubber layer and rubber ring not only can play bumper and absorbing shock, also plays certain seal action, has increased frictional force, alleviates the influence of vibrations to set screw effectively.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is a cross-sectional view of the present utility model.
Among the figure: 1 ailhead, 2 nail bodies, 3 rubber layers, 4 rubber rings.
Embodiment
As shown in Figure 1, the damping screw comprises ailhead 1 and nail body 2, and nail body 2 is provided with screw thread, and thread outer surface closely is pasted with a rubber layer 3 on the described nail body 2; Described ailhead 1 is provided with a rubber ring 4 with the face that nail body 2 is connected, and nail body 2 stretches out from the hollow space of rubber ring 4.
During use, rubber layer 3 and rubber ring 4 not only can play the effect of bumper and absorbing shock, also play certain seal action, have increased frictional force, alleviate the influence of vibrations to set screw effectively.The utility model is particularly suitable to be used in the occasion that there are vibrations in machinery, computer main etc.
