Abstract
The invention provides a bolt anti-falling gasket which is mainly characterized in that before a bolt (10) is installed, an anti-falling element head cone-shaped flange (23) is pressed into an upper through hole of a panel (30) through shrinkage of a head slotting (24), the cone-shaped flange (23) is pressed in the other side of the panel through shrinkage of the external diameter of the cone-shaped flange (23), the cone-shaped flange (23) and a tail gasket (21) are used for clamping the panel (30) in a front and back mode, interior barbs (22) are used for clamping the bolt (10), and the panel (30) and a main body (40) are installed. The bolt anti-falling gasket is used for preventing the bolt (10) from loosing in the process of dismantlement or vibration, but the bolt does not fall off from the panel. The bolt anti-falling gasket is simple in structure, two functions that the bolt is anti-falling and the gasket is anti-loosing are achieved, and the bolt anti-falling gasket can be matched with most bolts on the market for use.
Description
Technical field
The present invention relates to the anti-lost pad of a kind of screw, particularly relate to the anti-unloading device of a kind of screw derotation.
Background technique
Using fastening piece, during as screw, making toner screw easily during owing to vibration or dismounting, perhaps entering in other device.Cause screw to lose or disturb the operation of other device, especially in aviation, automobile or electric equipment industry, screw drops and causes other device to destroy or the normal operation of discharge interference.Developing many screw falling-proof apparatus for preventing that screw from dropping, as patent 93243247.6, is the Drop-proof screw device of one group of particular design.This fastening screw trip bolt device comprises screw, it also comprises support column, cutting ferrule and seal ring, one end inside of support column has the tapered sleeve of a band gap, and the tapered sleeve bottom has a recessed edge, and an end of cutting ferrule has a tapered flange, the other end has a cylindrical flange, screw is inserted in described cutting ferrule, and seal ring is inserted in the screw bottom, and cutting ferrule passes fastener and inserts support column.This Drop-proof screw device complex structure, parts are various, and cannot use pad when using the screw falling-proof apparatus.And when this Drop-proof screw device is installed, must form the lofty protuberance of being formed by support column, cutting ferrule and seals and other component in the outside, installation position, and make overall structure become big, be unfavorable for installation.And because above-mentioned loaded down with trivial details and bigger structure, in design, because the difference in space, the structure size that the different fixing parts need design is also obviously different.Therefore the design of this Drop-proof screw device is difficult to realize large batch of standardized production.

Summary of the invention
Based on the defective of prior art, the application provides a kind of project organization simple, anti-lost structure and the design of gasket construction one, and cost is low, and is easy to the anti-lost pad of screw of large-scale standardized production.
The invention provides the anti-lost pad of a kind of screw, anti-lost pad 20 is installed on the panel 30, head flange 23 with anti-lost pad one end toper trough of belt, 24 are pressed into through hole on the panel 30, head flange 23 external diameters shrink and are pressed into the other side of panel, clamp panel 30 with the lug boss front and back of afterbody pad portion 21, and inner hangnail 22 blocks screw 10, panel 30 is installed with main body 40.Afterbody pad portion 21 is along the radially extension of pad portion.
The invention provides a kind ofly be used to the pad that prevents that screw from dropping from installation panel, simple in structure, cost is low, and work is good.When preventing screw in unloading process or vibrations, even screw 10 becomes flexible or gets loose, but do not drop from panel.
Embodiment
One of them embodiment provided by the invention is: anti-lost pad 20 is pressed into through hole on the outer cover plate 30, and the anti-lost spacers of screw is in panel 30, and panel 30 and screw 10 are installed on the body 40.
Further, this pad comprises afterbody pad portion 21, axially extended neck and the head flange 23 that is positioned at neck finish along afterbody pad portion 21, has the through hole with screw fit in described afterbody pad portion 21, neck and the head flange 23, described head flange 23 is tapered, also be provided with at least one groove 24 on it, the inwall of described neck is provided with the anti-lost hangnail 22 of at least one screw.
Further, described at least one groove extends axially along head flange, and extends to neck.
Further, the anti-lost hangnail 22 of described screw is circumferential or axial arranged along the neck inwall.
Further, the anti-lost hangnail 22 of described screw is made of the projection that punching press on neck forms, and described punching press penetrates described neck.
Further, the anti-lost hangnail of described screw extends towards described head flange 23.
Further, the anti-lost hangnail 22 of described screw is one-body molded with described neck.
Further, the anti-lost pad of described screw is made by elastic material.
Further, the hardness of the anti-lost hangnail 22 of described screw is different with the hardness of neck.
Further, the hardness of the hardness ratio neck of the anti-lost hangnail 22 of described screw is little.
Further, the anti-lost pad of described screw is made by elastic metallic or elastomeric plastics.
In addition, can pass through stamped for the anti-lost structure of this screw, also can be by the injection moulding manufacturing.The anti-lost hangnail of screw can also can be manufactured in the neck inboard by additive methods such as welding by one-body molded.
In addition, the neck outside also can arrange projection, and this projection can radially be extended, and also can extend to the direction outside of flange or to the direction outside of pad portion.This protruding forming method also can equally with hangnail be that several different methods forms.
Be enlightenment with above-mentioned foundation desirable embodiment of the present invention, by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
