Abstract
The utility model provides a bolt with double screws. The bolt comprises a nut and the screws arranged below the nut, wherein the nut is connected with the two screws through a connecting piece, the screws are separately arranged, the screws are symmetrical right and left, one side at the lower end of each screw is provided with an oblique plane, the outer ring of each screw is provided with screw threads, two sides of the connecting piece is provided with raised blocks, the outer wall of the connecting piece is provided with raised triangular blocks, and the top end of the nut is provided with a groove. The utility model aims to design the bolt with the double screws, the arranged double screws are arranged on an object for preventing the object from shaking back and forth, the stability of the bolt is ensured, the raised blocks arranged on the two sides of the connecting piece prevent the bolt from dropping, and accordingly the service life of the bolt is prolonged.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly a kind of bolt with twin-screw.
Background technique
Fastening piece claims again standard piece, is used for two or more parts are fastenedly connected and form an integral body, and its applied range, this year is along with the develop rapidly of global industrial technology, the continuous increase of industrial requirement, the fastening piece demand gets more and more.
Bolt has hexagon head, round end, square spigot, countersunk head etc., wherein hexagon head is the most frequently used, general countersunk head is used in and requires to connect the smooth place that does not have projection, rear surface, because countersunk head may be screwed in part, round end also can be screwed in part, and the screwing force of square toes can be more greatly, but size is very large.
Bolt face commonly used is smooth, and tensility is poor, intensity a little less than, the phenomenon that usually comes off when fixed object, affect working life of object like this.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of bolt with twin-screw, the setting of twin-screw is fixed on object and is unlikely back and forth and rocks, guaranteed the stability of bolt, be arranged on the projection of link both sides, prevent bolt falling, thereby extend its working life.
The utility model provides a kind of bolt with twin-screw, comprise nut, and the screw rod that is arranged on described nut below, described nut connects two screw rods by link, and described screw rod is a minute groove setting, described screw rod is symmetrical set, one side is provided with inclined-plane in the screw rod lower end, and the screw rod outer ring is provided with screw thread, and the both sides of link are provided with projection, be provided with the corner block of projection on the link outer wall, the nut top is provided with groove.A kind of bolt with twin-screw of the purpose of this utility model design, the setting of twin-screw is fixed on object and is unlikely back and forth and rocks, guaranteed the stability of bolt, be arranged on the projection of link both sides, prevent bolt falling, thereby extend its working life, the intensity that the enhancing bolt is set of corner block, make bolt more durable, make its Applicable scope wider.
The utility model discloses a kind of a kind of improvement of the bolt with twin-screw, described projection is symmetrical set.The setting of this improvement projection, prevent bolt falling, thereby extend its working life.
The utility model discloses a kind of a kind of improvement of the bolt with twin-screw, the length of described screw rod is half of whole bolt length.The length of this improvement screw rod is half of whole bolt length, and such setting makes bolt more attractive in appearance, and durable, user friendly installation.
A kind of bolt with twin-screw of the purpose of this utility model design, the setting of twin-screw is fixed on object and is unlikely back and forth and rocks, guaranteed the stability of bolt, be arranged on the projection of link both sides, prevent bolt falling, thereby extend its working life, the intensity that the enhancing bolt is set of corner block, make bolt more durable, make its Applicable scope wider.
