Description

Novel bolt

Technical Field

The utility model relates to a five metals fastener technical field specifically is a novel bolt.

Background

The bolt is composed of a head and a screw (a cylinder with an external thread), is a fastener, is required to be matched with a nut and is used for fastening two parts with through holes, the connection mode is called bolt connection, the nut is screwed off the bolt to separate the two parts, and therefore the bolt connection also belongs to detachable connection.

The bolts are various in types, and the bolts and the gaskets are often used in combination, but now the area of the lower end of the bolt head is small, so that the pressure of the bolt head on the connected object cannot be effectively dispersed, the bolt can be broken in the using process (generally, after the bolt is broken, the broken part is basically a plane or a slightly inclined plane), after the broken part occurs, the broken bolt is difficult to detach from the connected object, and one bolt cannot be screwed or loosened in two ways, so that the bolt is inconvenient to use.

Disclosure of Invention

An object of the utility model is to provide a novel bolt to it is less to provide the lower terminal area who shows now bolt head in solving above-mentioned background art, thereby can not effectual dispersion bolt head to the pressure of quilt thing, and the cracked phenomenon can appear in the bolt in the use, after appearing splitting, hardly dismantle cracked bolt from the quilt thing, and a bolt can not screw up or unscrew with two kinds of modes, the problem of not being convenient for to use.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel bolt, includes the screw rod, the flat pad of upper end fixedly connected with of screw rod, the up end fixedly connected with flange head of flat pad, the cross recess has been seted up to the up end of flange head, the lower extreme laminating of flat pad is connected with the gasket.

Preferably, the screw rod, the flat pad and the flange head are of an integrated structure, threads are tapped on the outer side of the screw rod, the flat pad is circular, the flange head is located in the middle of the upper end face of the flat pad, the cross groove is located in the middle of the upper end face of the flange head, and the cross groove completely penetrates through the screw rod, the flat pad and the flange head.

Preferably, a through groove is formed in the middle of the upper end face of the gasket, the inner diameter of the through groove is slightly larger than the outer diameter of the screw rod, the upper end face of the gasket is a plane, the lower end face of the gasket is arc-shaped, and strip-shaped anti-slip teeth distributed in an annular mode are arranged on the lower end face of the gasket.

Preferably, the lower end face of the gasket is a plane with strip-shaped anti-slip teeth.

Preferably, the lower end face of the gasket is an inclined face with strip-shaped anti-slip teeth.

Compared with the prior art, the beneficial effects of the utility model are that: this novel bolt, cross recess and flange head through setting up, can use the screwdriver of cross head or spanner to screw up or loosen this bolt, and the cross recess runs through the flange head completely, flat pad and screw rod, thereby under the cracked condition of this bolt, still can dismantle this bolt fast through the screwdriver of cross head, flat pad through setting up, can increase this bolt and by the area of contact between the link, thereby can disperse the flange head to the pressure by the link, gasket through the three kinds of shapes that set up, can be applicable to the junction by the link different shapes, and the non slipping spur of terminal surface can be embedded into by the link under the gasket, prevent that the gasket from rotating, friction will take place between flat pad and the gasket of this bolt like this, thereby the sudden change of moment can not appear, and convenient to use.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a novel bolt, includes screw rod 1, flat 2, flange head 3, cross recess 4, gasket 5, leads to groove 6, antiskid tooth 7, and the flat 2 that fills up of upper end fixedly connected with of screw rod 1 fills up, and the up end fixedly connected with flange head 3 of flat 2 that fills up, cross recess 4 has been seted up to the up end of flange head 3, and the lower extreme laminating of flat 2 that fills up is connected with gasket 5.

Further, screw rod 1, flat 2 and flange head 3 structures as an organic whole, the screw thread has been attacked in the outside of screw rod 1, flat 2 of filling up is circular, flange head 3 is located the intermediate position of flat 2 up ends of filling up, cross slot 4 is located the intermediate position of flange head 3 up end, cross slot 4 runs through screw rod 1 completely, flat 2 and flange head 3 fill up, through flat 2 of setting up, increased with gasket 5 or the area of contact by the connector, the pressure of dispersion flange head 3 to the connector, through the cross slot 4 that sets up, this bolt can be screwed up or unscrewed through the screwdriver that can pass through, and under the cracked condition of this bolt, still can dismantle this bolt fast, through the flange head 3 that sets up, can screw up or unscrew this bolt through the spanner, convenient to use.

Furthermore, a through groove 6 is formed in the middle of the upper end face of the gasket 5, the inner diameter of the through groove 6 is slightly larger than the outer diameter of the screw rod 1, the upper end face of the gasket 5 is a plane, the lower end face of the gasket 5 is arc-shaped, strip-shaped anti-slip teeth 7 distributed in an annular mode are arranged on the lower end face of the gasket 5, the joint of the gasket 5 suitable for a connected object is in a spherical shape recessed downwards, the friction force between the bolt and the connected object is increased through the arranged gasket 5, the anti-slip teeth 7 on the lower end face of the gasket 5 can be embedded into the connected object, the gasket 5 is prevented from rotating, the flat cushion 2 of the bolt can be rubbed with the gasket 5, and therefore sudden change of moment cannot occur.

Furthermore, the lower end surface of the gasket 5 is a plane with the strip-shaped anti-slip teeth 7, and the connection position of the gasket 5 suitable for the connected object is a plane.

Furthermore, the lower end surface of the gasket 5 is an inclined surface with a strip-shaped anti-slip tooth 7, and the connecting position of the gasket 5 suitable for the connected object is an inclined surface, so that the connection between the bolt and the connected object is more stable.

The working principle is as follows: firstly, in the using process, firstly, according to the specific shape of the joint of the connected object, selecting a proper gasket 5, enabling a screw 1 of the bolt to penetrate through the gasket 5 to align with the joint of the connected object, then aligning a wrench with the flange head 3 or using a screwdriver with a crosshead to align with the cross slot 4, then screwing the bolt, after screwing, embedding the anti-slip teeth 7 on the lower end surface of the gasket 5 into the connected object to prevent the gasket 5 from rotating, so that friction can occur between the flat pad 2 and the gasket 5 of the bolt, and sudden change of moment can not occur, and meanwhile, the cross slot 4 completely penetrates through the screw 1, the flat pad 2 and the flange head 3, so that the bolt can be rapidly disassembled and is convenient to use under the condition that the bolt is broken.

It should be finally noted that the above only serves to illustrate the technical solution of the present invention, and not to limit the scope of the present invention, and that simple modifications or equivalent replacements performed by those skilled in the art to the technical solution of the present invention do not depart from the spirit and scope of the technical solution of the present invention.
