Abstract
The invention discloses a screw washer. The screw washer comprises a washer body. A central hole is formed in the center of the washer body. An inward-concave circular arc groove is formed in the washer body. A friction protrusion is embedded in the upper surface of the washer body. The periphery of the washer body is fixedly connected with a flange. A friction protrusion is embedded in the lower surface of the washer body. The thickness of the flange is one second of the thickness of the washer body. The screw washer is simple in structure and reasonable in design, and the inward-concave circular arc groove is formed in the washer body so that the elasticity of the washer can be improved; the friction protrusions are embedded in the upper surface and the lower surface of the washer body, and friction force of the washer and the object surface is increased, so that positioning is easy; and the periphery of the washer body is fixedly connected with the flange, and the thickness of the flange is one second of the thickness of the washer body, so that the washer is easy to take on the smooth object surface.
Description
Technical field
The present invention relates to machinery five metals component technology field, particularly relate to a kind of screw washer.
Background technology
When some waste and old electric engineering goods are keeped in repair, substantial amounts of screw washer can be used, in the prior art, screw washer is typically the round-meshed thin slice of Intermediate Gray, edge is arrived basically identical in the middle of screw washer, but when existing pad is placed on more smooth body surface, owing to light weight, thin being not easy of thickness are taken.If pad endoporus is relatively big, and screw rod is less, then be also not easy location at smooth surface.
Summary of the invention
The present invention seeks to the disadvantages mentioned above overcoming prior art to exist, it is provided that a kind of accurate positioning, the screw washer easily taken.
For achieving the above object, the technology used in the present invention means are: a kind of screw washer, including shim body, shim body center offers a centre bore, offering indent arc groove in shim body, the upper surface of shim body is embedded with friction protrusion, and shim body periphery fixes flange connector.
Further, the lower surface of shim body is embedded with friction protrusion.
Further, thickness of flange is 1/2nd of shim body thickness.
The invention has the beneficial effects as follows: simple in construction, reasonable in design, shim body offers indent arc groove, so can increase the elasticity of pad；All it is embedded with friction protrusion on two surfaces up and down of shim body, increases the frictional force of pad and body surface, easily position；Shim body periphery fixes flange connector, and thickness of flange is 1/2nd of the second body thickness, easily takes at more smooth body surface.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the side view of the present invention.
In figure: 1, shim body, 2, centre bore, 3, friction protrusion, 4, flange, 5, indent arc groove.
Detailed description of the invention
A kind of screw washer as depicted in figs. 1 and 2, including shim body 1, shim body 1 center offers a centre bore 2, shim body 1 offers indent arc groove 5, the upper surface of shim body 1 is embedded with friction protrusion 3, and shim body 1 periphery fixes flange connector 4.
The lower surface of described shim body 1 is embedded with friction protrusion 3.
Described flange 4 thickness is 1/2nd of shim body 1 thickness.
Present configuration is simple, reasonable in design, shim body offers indent arc groove, so can increase the elasticity of pad；All it is embedded with friction protrusion on two surfaces up and down of shim body, increases the frictional force of pad and body surface, easily position；Shim body periphery fixes flange connector, and thickness of flange is 1/2nd of the second body thickness, easily takes at more smooth body surface.
The above, the only detailed description of the invention of the present invention, it is not limited to this, any those familiar with the art, in the technical scope that the invention discloses, can readily occur in change or replace, should contain within protection scope of the present invention.
Claims (3)
