Description

Anchoring nail for decoration and finishing material

[ technical field ] A method for producing a semiconductor device

The utility model relates to a decoration and finishing technical field, specificly relate to a decoration and finishing is anchor nail for material.

[ background of the invention ]

In the decoration industry, anchor nails are often used. The anchoring nail is a fixing piece connected between the wall body and the heat insulation plate and consists of a galvanized screw, a nylon expansion pipe and a fixing wafer. The insulating layer is divided into a plurality of specifications according to different thicknesses of the insulating layer. Widely used in building decoration. The anchoring nail has the advantages of ageing resistance, temperature shock resistance, corrosion resistance, cold resistance, heat resistance, high bearing capacity, high pressure bearing capacity and good tensile property; the cable is not easy to deform after being loaded, and has moisture resistance, vibration damping, noise absorption, good insulativity and the like. The installation is simple and convenient, and the hammering can, does not need special mounting tool. The high-temperature resistant and fire-resistant anchoring nail used in the cement industry is made of chromium, nickel and titanium.

The existing anchoring nails mainly have the following disadvantages: the anchor nail is not suitable for soft quality decoration and finishing materials, and the hole fixed with the anchor nail can deform after the soft decoration and finishing materials are used for a long time, so that the anchor nail is easy to fall off.

In view of the above, it is desirable to provide an anchor nail for decoration materials to overcome the disadvantages of the prior art.

[ Utility model ] content

The utility model aims at providing an anchoring nail for decoration and finishing materials, wherein the opening crack on the pipe sleeve is cracked and expanded outwards after being extruded by a screw, and the whole hole is full of expansion, and a plurality of barb structures are used for increasing friction force and preventing falling off; after the screw is rotated in the direction and pulled out, the screw can be pulled out together with the pipe sleeve.

In order to achieve the purpose, the utility model provides an anchoring nail for decoration materials, which comprises a pipe sleeve and a screw matched with the pipe sleeve;

a stepped hole is formed in the pipe sleeve, internal threads are formed in the inner wall of the bottom end of the stepped hole, a pair of opening cracks and a plurality of barb structures are formed in the outer surface of the bottom end of the pipe sleeve, the pair of opening cracks are symmetrically arranged, the plurality of barb structures are located between the pair of opening cracks, and an anti-sinking disc is arranged at the top end of the pipe sleeve; the bottom of screw is equipped with the external screw thread, the top of screw is equipped with the plum blossom screw head.

In a preferred embodiment, the outer surface of the upper end of the tube sleeve is provided with a number of tongue structures.

In a preferred embodiment, the top edge of the stepped hole is provided with a bevel structure.

In a preferred embodiment, the pipe sleeve is an ABS resin.

Compared with the prior art, the utility model provides a pair of anchor nail for decoration and finishing material's beneficial effect lies in: the opening crack on the pipe sleeve is extruded by the screw to crack and expand outwards to fill the whole hole, and the plurality of barb structures are used for increasing the friction force and preventing the falling off; after the screw is rotated in the direction and pulled out, the screw can be pulled out together with the pipe sleeve.

[ detailed description ] embodiments

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1, the present invention provides an anchoring nail 100 for decoration materials.

In an embodiment of the present invention, the anchor nail 100 for decoration and finishing material includes a pipe sleeve 10 and a screw 20 used in cooperation with the pipe sleeve 10.

Specifically, referring to fig. 2, a stepped hole 11 is formed inside the pipe sleeve 10, an internal thread 12 is formed on an inner wall of a bottom end of the stepped hole 11, a pair of tension slits 13 and a plurality of barb structures 14 are formed on an outer surface of the bottom end of the pipe sleeve 10, the pair of tension slits 13 are symmetrically arranged, the plurality of barb structures 14 are located between the pair of tension slits 13, and an anti-sinking disc 15 is arranged at a top end of the pipe sleeve 10; the bottom end of the screw 20 is provided with an external thread 21, and the top end of the screw 20 is provided with a plum-blossom screw head 22.

It can be understood that, when in use, the pipe sleeve 10 needs to be inserted into a reserved hole of an inner wall or an outer wall decorative plate, then the front section part of the screw 20 is inserted into the stepped hole 11 of the pipe sleeve 10, then a tool is used for continuously screwing the screw 20 through the plum screw head 22, the expansion crack 13 on the pipe sleeve 10 is extruded by the screw 20 and then cracks and expands outwards to fill the whole hole, and the barb structures 14 are used for increasing friction force and preventing falling off. After the screw 20 is rotated in the direction and pulled out, it can be pulled out together with the sleeve 10. The sink prevention plate 15 prevents the entire anchor nail 100 for decoration and finishing material from entering the prepared hole of the inner wall or the outer wall decoration plate.

Further, the outer surface of the upper end of the pipe housing 10 is provided with a plurality of tongue structures 16. Friction is further enhanced by the plurality of tab structures 16.

Further, the top end edge of the stepped hole 11 is provided with a slope structure 17. The insertion of the screw 20 into the pipe sleeve 10 is facilitated by the ramp structure 17.

Further, the pipe sleeve 10 is ABS resin. ABS resin has higher strength than PS, has very good fluidity during molding, and is a very common material used in the injection molding industry.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
