fig. 2 is a side view of a body of an elastic flat washer having a locking function;
fig. 3 is a schematic structural diagram of a cushion block of an elastic flat washer with anti-loosening function.
In the figure: 1. a main body; 2. an anti-loosening mechanism; 201. a fixing ring; 202. cushion blocks; 203. a rubber skirt; 204. positioning a groove; 205. a rubber block.
Detailed Description
Referring to fig. 1 to 3, in an embodiment of the present invention, an elastic flat washer with anti-loosening function includes a main body 1 and an anti-loosening mechanism 2, which are disposed on the top and bottom of the main body 1, the anti-loosening mechanism 2 includes a fixing ring 201 and a rubber skirt 203, the fixing ring 201 is connected to the top of the main body 1 by welding, and the rubber skirt 203 is connected to the bottom of the main body 1 by sleeving.
This kind of elasticity plain washer with locking function, when using this device, can install main part 1 at the outer wall of bolt, the bolt will run through to the inside of connecting piece through the screw thread this moment, remove through the pivoted mode, the top and the bottom of main part 1 all receive the extrusion under the turning force effect of bolt, fixed ring 201 on main part 1 top this moment will contact with the bolt surface and receive the extrusion, fixed ring 201 top other locking spare part that moves of mechanism 2 will also take place to warp under the effect of extrusion force, and the rubber shirt rim 203 of main part 1 bottom will also contact with the connecting piece, receive the compressive deformation, the protruding marginal portion in below of constant head tank 204 this moment, will the rebound, take place to deform, further increase the frictional force between main part 1 and the connecting piece.
In fig. 2-3: locking mechanism 2 still includes cushion 202, constant head tank 204, and cushion 202 is through the mode of bonding at the top of solid fixed ring 201, and constant head tank 204 sets up between main part 1 and rubber skirt 203, and the top of cushion 202 is provided with block rubber 205 through mould integrated into one piece.
This kind of elasticity plain washer with locking function, when solid fixed ring 201 receives the external force extrusion, the cushion 202 of solid fixed ring 201 outer wall will also receive external extrusion force, the block rubber 205 on cushion 202 top will take place to warp under the external force effect, block rubber 205 will be close to each other under the inclined plane effect, be the trapezium structure, increase the frictional force between main part 1 and the bolt, and rubber shirt rim 203 receives the extrusion force and will the rebound, the protruding marginal portion in rubber shirt rim 203 below will move to the inboard of constant head tank 204, and deformation also takes place for the whole of rubber shirt rim 203, increase the frictional force between main part 1 and the connecting piece.
In fig. 2-3: the quantity of cushion 202 is provided with a plurality ofly, and a plurality of cushion 202 evenly distributed is at the top of solid fixed ring 201, and the cross section of rubber piece 205, cushion 202 is "concave" style of calligraphy state, and the outer wall of rubber shirt rim 203 is the annular state, and the outer wall of rubber piece 205 is the inclined plane state.
This kind of elasticity plain washer with locking function, when the block rubber 205 received external extrusion force, because the outer wall of block rubber 205 is the inclined plane state, so block rubber 205 will take place deformation under the exogenic action, and two block rubbers 205 will be close to each other, make the transversal trapezium structure of personally submitting of block rubber 205, cushion 202, increase the frictional force between main part 1 and the bolt.
