Fastening nail sleeve assembly of simple board painting

Abstract

The invention discloses a fastening nail sleeve assembly of a simple board painting. The fastening nail sleeve assembly comprises a helical-tooth nail and a helical-tooth expansion sleeve, wherein thehelical-tooth nail comprises a modeling cap and a column body; the column body comprises a smooth section and a helical-tooth section; the helical-tooth section comprises a plurality of ring helicalteeth, and a ring tooth slot is formed between adjacent ring helical teeth; the helical-tooth expansion sleeve comprises a column tube body, and a plurality of layers of elastic helical-tooth groups are distributed on the peripheral surface of the column tube body, and the elastic helical-tooth group at each layer comprises a plurality of elastic helical teeth which are uniformly distributed peripherally; an avoiding hole is formed in the side wall, on the position of each elastic helical tooth, of the column tube body, an elastic helical surface is connected to the side wall of the avoiding hole, and a vertical surface is not connected to the side wall of the avoiding hole. A drawing board hole is directly formed in a simple board drawing board body, and a standard internal sleeve part issleeved by the drawing board hole, so that the drawing board hole is sealed in a matched mode by a drawing board hole inner sleeve. The simple board painting is completely adhered and fixed on a wall, and the ring helical teeth and the helical-tooth expansion sleeve can generate inward sliding pressure, so that a gap is not formed between the simple board painting and a wall body.

Description

technical field [0001] The invention belongs to the technical field of decorative accessories for hanging pictures, and in particular relates to a nail set assembly for fixing simple board paintings. Background technique [0002] Most of the common wall hanging pictures at present have a jagged hook cover on the top of the back side of the picture hanging, and the self-tapping thread is used to fix the hanger cover on the wooden material frame on the back of the drawing board. When installing, you need to smash nails on the wall first, and then use the hook sleeve on the top of the back of the picture to hang on the corresponding nail. This way of hanging pictures will cause the drawing board to not be in full contact with the wall due to the protruding hook sleeve, which will cause problems. There are gaps, and the upper and lower gaps are inconsistent. For paintings with high artistic taste, this mounting method has disadvantages and affects aesthetics. This method of han...

Problems solved by technology

When installing, you need to smash nails on the wall first, and then use the hook sleeve on the top of the back of the picture to hang on the corresponding nail. This way of hanging pictures will cause the drawing board to not be in full contact with the wall due to the protruding hook sleeve, which will cause problems. gap, and the upper and lower gaps are inconsistent. For paintings with high artistic taste, this mounting method has disadvantages that affect aesthetics

This method of hanging pictures is especially not suitable for simple board paintings. Simple board paintings require the picture and drawing board to be simple and simple, with clear and smooth lines and outlines. However, self-tapping threads need to be drilled into the top of the back of the drawing board, so the upper side of the drawing board has a hard border. Usually, the wooden frame is not suitable for many light boards, and the middle part of the drawing board is weak or hollow. Only when the frame is made of hard material and hollow, the part of the picture will be highlighted and not smooth. Therefore, it is necessary to carry out the mounting method of the current simple board painting. Improve

On the other hand, there is blindness in the nailing of the existing hanging pictures. Because the height of the hook sleeves on the back of the skateboard is inconsistent, it is often installed by the user. When positioning and measuring, it is difficult to determine the actual position of the hanging sleeve after the skateboard is attached to the wall. This leads to inaccurate nail positions, and because it is difficult to nail nails on the wall, it is prone to deflection. Once deflection occurs or deflection occurs due to inaccurate measurement, deflection will appear after hanging the picture, which will affect the aesthetic sense

If the nail position of the wall is replaced, the surface of the wall will be damaged due to repeated nailing, and a lot of time and energy will be wasted

The existing way of hanging pictures is safe to stand still, but because children are curious and active, they may easily touch the hanging pictures out of curiosity without supervision, which may cause the hanging pictures to fall accidentally and injure the child
