Abstract
A anti- dismounting screw consists of a convex core in center of spiral groove of screw cap which makes the normal screwdriver can not insert in. The matched screwdriver has a concave completely matched in size with the convex of the screw to obtain reliable connection.
Description
Technical field
The present invention relates to a kind of novel anti-dismounting screw, simultaneously, also relate to a kind of swing arm supporting with it.
Background technique
The key position of many instruments, equipment, household electric appliance is not allow layman's dismounting, needs to use some special secure components.Concentrated the parts of refrigerator most critical such as the press chamber of refrigerator, during the back cover of stationary press chamber,, can prevent from that the user from dismantling privately refrigerator is caused unnecessary harm if fix with special screw.When needing repairing, also can only dismantle with special tool by the professional workforce.
Summary of the invention
The object of the present invention is to provide a kind of anti-dismounting screw.Simultaneously, the present invention also aims to provide a kind of and anti-dismounting screw supporting swing arm.
In order to achieve the above object, technical program of the present invention lies in having adopted a kind of anti-dismounting screw, comprise screw rod and nut, the spin slot center of the nut of this screw is provided with a protruding core.
Described protruding core can be cylindrical, conical, rectangular.
Described spin slot can be triangle, quadrilateral, polygonal star.
The center of revolving head of this swing arm is provided with a shrinkage pool.
Described shrinkage pool can be circular hole, conical bore, rectangular hole.
Described revolve the head can be trigonocephalia, square head, polygonal star head.
The center of the spin slot of the nut of anti-dismounting screw of the present invention is provided with a protruding core, and this just makes common swing arm may not insert in the special-shaped grooved screw groove, thereby also just can not dismantle with fastening, can only be dismantled with special-purpose swing arm instrument by the professional workforce.The center of revolving head of swing arm is provided with a shrinkage pool, and the lucky and special-shaped grooved screw groove of the size of this shrinkage pool and degree of depth convex core matches, thereby has realized the connection of this screw and fastening.Use special-shaped grooved screw of the present invention to reach and connect with its supporting swing arm, simple and convenient, connect reliably, can realize manufacturing the special connection request of producer fully.
