Further, the outer end of the mounting head is provided with a polygonal counter bore.

The beneficial effects of the utility model are as follows:

1. The convex tooth structure can form larger friction force in the structure, so that the installation is firmer and the safety is high.

2. The bolt matched with the depth of the internal thread of the nut head can be used, so that the bolt is less exposed, the occupied installation space is avoided, and the applicability is strong.

Detailed Description

The utility model relates to a pre-buried nut component, which is described in detail below with reference to specific embodiments.

As shown in fig. 1, 2 and 3, an embedded nut member comprises a rod body 1 and a nut head 2 at the end of the rod body 1, wherein an anti-falling member is arranged on the rod body 1, the anti-falling member is a protruding portion at the outer side of the rod body 1, and an internal thread is arranged at the end of the nut head 2.

As shown in fig. 6, when the device is used, the device is used as an embedded part to be embedded into structures such as a wall body and a prefabricated part according to design requirements, and when an article is installed or the structures are connected, a structure to be connected is fixed on the nut head 2 by using bolts. When the nut is embedded, the nut head 2 can be completely embedded into the screw hole according to design requirements, and the nut head 2 can be exposed. The protruding part can be firmly locked in the structure, so that the large torsion and bearing force can be borne, and the falling and loosening situations are avoided.

When the component is required to be applied to a wall-penetrating scene, nut heads can be arranged at two ends of the rod body.

The shape of the rod body can be round, square, trapezoid or other irregular shapes. The middle part of the rod body 1 is provided with a through hole communicated with screw holes in the nut heads 2 at two ends so as to be suitable for threading, water passing and other scenes.

As shown in fig. 7, the nut head 2 may be integrally constructed with the rod body 1.

The bolt matched with the depth of the internal thread of the nut head 2 is used, so that the threaded part of the bolt can completely enter the nut head 2, and the installation accuracy is improved in the case of dry hanging operation of some scenes such as curtain walls, heat insulation boards and the like due to the fact that the exposed part of the installation bolt is less, the occupied installation space is avoided.

As shown in fig. 1 and 2, the protruding part is a protruding tooth 3 evenly distributed around the outer wall of the rod body 1. The structure of the convex teeth 3 can form larger friction force in the structure, so that the installation is firmer.

As shown in fig. 3, the protruding part is a limiting side plate 4 on the outer wall of the rod body 1, and can also bear the effect of larger torsion and bearing capacity.

As shown in fig. 1, when the structure is a concrete structure, the nut head 2 is in a frustum shape, so that stress can be effectively dispersed to a wider area, and the damage risk of concrete at the connecting part is reduced. In addition, the constructor can more easily observe and judge the position and direction of the nut head 2, thereby ensuring the accuracy and reliability of the connection. In other embodiments, as shown in fig. 2, the nut head 2 is square, but may be circular, elliptical, or the like in other embodiments.

As shown in fig. 4 and 5, the nut head further comprises a mounting head 5, external threads matched with the nut head 2 are arranged on the outer side of the mounting head 5, and a limit gasket 6 is arranged on the outer side of the mounting head 5. The mounting head 5 is used for a transition adapter, so that the transition adapter is suitable for some scenes requiring external mounting of bolts. The position of the limit gasket 6 is matched with the depth of the internal thread in the nut head 2, so as to remind constructors of installing the nut in place.

The outer end of the mounting head 5 is provided with a polygonal counter bore 7 so that constructors can screw the mounting head 5 on the nut head 2.
