Description

Technical Field

[0001] The invention relates to the field of expansion screws, in particular to an expansion screw for building decoration. Background Art

[0002] Expansion screws generally refer to metal expansion screws. The fixation of expansion screws uses the wedge-shaped slope to promote expansion and generate friction and grip to achieve a fixing effect. One end of the screw is threaded and the other end is taper. It is wrapped with an iron sheet (some are steel pipes), and half of the iron cylinder (steel pipe) has several cuts. They are stuffed together into the holes made in the wall, and then the threads are locked. The threads pull the screws outward and pull the taper into the iron cylinder. The iron cylinder is expanded and then tightly fixed to the wall. It is generally used for fastening guardrails, awnings, air conditioners, etc. on cement, bricks and other materials. Existing expansion screws are not fixed firmly, and when used at a higher place, it is inconvenient for users to operate and easily cause damage to themselves. At the same time, there are safety issues in high-altitude operations. Summary of the invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art and to provide an expansion screw for building decoration.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] An expansion screw for building decoration comprises an expansion screw body, an expansion screw sleeve and an auxiliary rod, wherein the top of the screw body is provided with embedded teeth, the lower end of the screw body is provided with a hook rope, the screw body is provided with threads, the expansion screw sleeve is fixedly installed with a knocking cap, the auxiliary rod is provided with a limit block, a steel rope and a mounting plate, the limit block is arranged at the end of the auxiliary rod, one end of the steel rope is rotatably installed on the mounting plate, and the other end of the steel rope is fixedly installed on the auxiliary rod.

[0006] Preferably, the embedded tooth is in the shape of a fang, the connection between the embedded tooth and the expansion screw body is thicker, and the top of the embedded tooth is thinner.

[0007] Preferably, the auxiliary rod is fixedly mounted with the limit block, and the limit block is provided with a limit block.

[0008] Preferably, there are two mounting plates, and the steel rope is provided between the two mounting plates and the auxiliary rod.

[0009] Preferably, the area of ​​the limiting block is larger than the area of ​​the knocking cap.

[0010] Preferably, the mounting plate and the steel rope are both located between the limiting block and the end of the auxiliary rod.

[0011] The beneficial effects of the present invention are:

[0012] 1. The present invention is provided with an expansion screw body, embedded teeth, threads, an expansion screw sleeve, a striking cap and a hook rope. When the expansion screw body enters into the wall, the embedded nail will first enter into the wall, and at this time the embedded nail will be deformed and embedded into the wall, so that the expansion screw body is firmly fixed and will not loosen after long-term use. The hook rope is used to facilitate hooking things on the expansion screw body. This arrangement increases the function of the expansion screw.

[0013] 2. The present invention arranges the auxiliary rod, the limit block, the mounting plate and the steel rope. When the expansion screw body is used at a high place, the knocking cap is inserted into the limit block, and the expansion screw body can be knocked into the wall by knocking the auxiliary rod. The steel rope can prevent the auxiliary rod from being deformed and bent when being knocked. This arrangement makes it convenient for users to use the expansion screw body at different heights.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-4An expansion screw for building decoration comprises an expansion screw body 1, an expansion screw sleeve 3 and an auxiliary rod 10. The top of the screw body 1 is provided with an embedded tooth 2, the lower end of the screw body 1 is provided with a hook rope 5, the screw body 1 is provided with a thread 4, the expansion screw sleeve 3 is fixedly installed with a knocking cap 6, the auxiliary rod 10 is provided with a limit block 7, a steel rope 8, and a mounting plate 9, the limit block 7 is arranged at the end of the auxiliary rod 10, one end of the steel rope 8 is rotatably installed on the mounting plate 9, and the other end of the steel rope 8 is fixedly installed on the auxiliary rod 10.

[0021] The embedded tooth 2 is in the shape of a fang, and the connection between the embedded tooth 2 and the expansion screw body 1 is thicker, and the top of the embedded tooth 2 is thinner. The auxiliary rod 10 is fixedly installed with a limit block 7, and the limit block 7 has a limit block. There are two mounting plates 9, and steel ropes 8 are provided between the two mounting plates 9 and the auxiliary rod 10. The area of ​​the limit block is larger than the area of ​​the knocking cap 6, and the mounting plate 9 and the steel rope 8 are both located between the limit block 7 and the end of the auxiliary rod 10.

[0022] Working principle: When the present invention is in operation, when the installation position is low, the expansion screw body 1 is made to enter the wall by knocking the knocking cap 6. At this time, the embedded nail 2 will enter the wall first, and the embedded nail 2 will be deformed and embedded in the wall. After the expansion screw body 1 is fully entered, it is locked by the thread 5, so that the expansion screw body 1 is firmly fixed, ensuring that it will not loosen after long-term use. The hook rope 5 is convenient for hooking things on the expansion screw body 1. This setting increases the function of the expansion screw. When the expansion screw body 1 is used at a high place, the knocking cap 6 is inserted into the limit block 7, and the expansion screw body 1 can be knocked into the wall by knocking the auxiliary rod 10. The steel rope 8 can prevent the auxiliary rod 10 from deforming and bending when being knocked. This setting makes it convenient for users to use the expansion screw body 1 at different heights. To save time and labor, the auxiliary rod solves the problems of labor time and efficiency such as not climbing a ladder.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
