Embodiment Construction

[0041] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0042] see Figure 1-2 , this embodiment provides a screw-in back bolt with a stress-free function, which is not only suitable for the connection of thin veneer panels such as stone veneer panels, glass veneer panels, ceramic veneer panels, and tile veneer panels with pendants, but also It is suitable for installing various devices on various walls, and can also be applied to the assembly of toys, including screw rod 110, outer cylinder 120 and movable block 130;

[0043] The screw 110 is provided with an external thread, and the inner wall of the outer cylinder 120 is provided with an internal thread adapted to the external thread of the screw 110;

[0044] The side wall of the outer cylinder 120 is provided with one or more sliding...

Abstract

The invention relates to a screw-in back bolt with a stress-free function. The screw-in back bolt comprises a screw, an outer cylinder and one or more movable blocks; an external thread is arranged onthe screw, and an internal thread matched with the external thread of the screw is arranged on the inner wall of the outer cylinder; one or more sliding grooves are formed in the side wall of the outer cylinder, and the sliding grooves comprise matching points and matching positions; one ends of the movable blocks are provided with shaft parts, and the other ends of the movable blocks are provided with convex block parts; the shaft parts of the movable blocks are arranged in the matching points, and the convex block parts are movably arranged in the matching positions; and after the screw isused for being screwed into the outer cylinder, and the convex block parts of the movable blocks are limited to enable parts or all of the convex block parts to be protruded out of the surface of theouter cylinder. The back bolt and a veneer are very reliably connected, sliding of the movable blocks does not generate stress on the veneer, does not damage the veneer and meanwhile does not generateexternal resistance to rotation of the screw, and thus the screw is more conveniently and more rapidly screwed into the outer cylinder.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to a screw-in back bolt with a stress-free function. Background technique [0002] With the development of construction engineering technology and economic level, the decoration of the surface of the building wall has changed from the traditional use of cement lime mortar, painting to imitation porcelain, and now it has the functions of beauty, environmental protection, easy cleaning, sound insulation, heat insulation and so on. Decorative panels such as wall coverings, diatom mud, porcelain panels, marble and granite panels. Especially in some high-end and high-end homes and hotels, meeting rooms, offices and commercial buildings, marble and granite slabs are mostly used as veneer panels to decorate the walls. While the veneer panel decorates the wall, the veneer panel needs to be fixed on the wall through the pendant, and the connection between the pendant and the veneer panel ...
