Abstract
The utility model provides a bolt for increasing a friction force. The bolt comprises an arc nut and a screw rod, wherein a connecting piece is arranged between the arc nut and the screw rod, the outer edge of the screw rod is provided with threads, the connecting piece is provided with reinforcing ribs, the reinforcing ribs are in mutual cross arrangement, the lower end of the arc nut is provided with anti-slip teeth, the upper end of the arc nut is provided with a groove, and the groove is a cross groove or a slotted groove. According to the bolt for increasing the friction force, provided by the utility model, when the anti-slip teeth under the arc nut are clamped in a component, the friction force of the bolt and an accessory is increased, and the bolt is not easy to slip.
Description
Technical field
The utility model relates to technical field of fastening, particularly a kind of bolt that improves frictional force.
Background technique
Bolt is needed to cooperate with nut by head and a screw rod class fastening piece dimerous, is used for being fastenedly connected two with zero of through hole, this Connecting format claims bolt to connect, as nut is screwed off from bolt, have to make these two parts separately, be to belong to removably connect therefore bolt connects.
Fastening piece is to be fastenedly connected with and to use very widely class mechanical parts, on various machineries, equipment, vehicle, boats and ships, railway, bridge, building, structure, instrument, instrument, instrument and articles for use etc., can see fastening piece miscellaneous, its feature is that description is various, the performance purposes is different, and standardization, seriation, unitized kind of degree are also high, therefore also have the people that one class fastening piece of existing NBS is called standard fasteners.
Bolt smooth surface commonly used, frictional force is little, and it is firmly inadequate when connecting, and easily comes off, and bolt can not normally be used, and causes the frequent bolt, the waste material, common bolt strength is poor, the phenomenon of fracture usually occurs.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of bolt that improves frictional force, when the slideproof tooth that arranges when circular arc nut below snaps in parts, increased the frictional force of bolt and accessory, make bolt be not easy to skid.
The utility model provides a kind of bolt that improves frictional force, comprise circular arc nut, screw rod, between described circular arc nut and screw rod, be provided with link, described screw rod outer rim is provided with screw thread, be provided with stiffening rib at described link, described stiffening rib is mutually arranged in a crossed manner, is provided with slideproof tooth in circular arc nut lower end, circular arc nut upper end is provided with a groove, and described groove is cross recess or straight groove.A kind of bolt that improves frictional force of the purpose of this utility model design, when the slideproof tooth that arranges when circular arc nut below snaps in parts, increased the frictional force of bolt and accessory, make bolt be not easy to skid, the setting of stiffening rib makes bolt turning to such an extent that be not easy fracture in the process, prolongs the working life of bolt.
The utility model discloses a kind of a kind of improvement that improves the bolt of frictional force, described slideproof tooth is symmetrical set, and described slideproof tooth is at least 3 roads.This improved purpose is the frictional force that increases bolt and surface of contact, prevents that bolt from skidding fixedly the time, improves the installation efficiency of bolt.
The utility model discloses a kind of a kind of improvement that improves the bolt of frictional force, the thickness of described stiffening rib is 3-7mm.The thickness of the utility model stiffening rib is blocked up, the waste material, and thickness is excessively thin, and stablizing effect is relatively poor, and the thickness of stiffening rib is 5mm after tested, and bolt is not easy fracture.
The utility model discloses a kind of a kind of improvement that improves the bolt of frictional force, the radian of described circular arc nut is 20 °-60 °.This improvement can be changed according to client's demand the radian of circular arc nut.
A kind of bolt that improves frictional force of the purpose of this utility model design, when the slideproof tooth that arranges when circular arc nut below snaps in parts, increased the frictional force of bolt and accessory, make bolt be not easy to skid, the setting of stiffening rib makes bolt turning to such an extent that be not easy fracture in the process, prolongs the working life of bolt.
