Description

Technical Field

[0001] The utility model relates to the technical field of expansion nails, in particular to a wall expansion nail. Background Art

[0002] Expansion nails are generally used to fasten guardrails, awnings, air conditioners, etc. on cement, bricks and other materials. However, its fixation is not very reliable. If the load has a large vibration, it may become loose or fall off.

[0003] Although the existing expansion nails can be fixed to the wall, there are still some problems. First, the current expansion nails often expand the expansion tube by screwing bolts into the expansion tube. The installation process of this expansion nail needs to rely on bolts and the installation process is cumbersome. Second, after the bolts of the current expansion nails are removed, the fixation between the expansion nails and the wall fails. Therefore, a wall expansion nail is needed to solve the above problems. Utility Model Content

[0004] The main purpose of the utility model is to provide a wall expansion nail, aiming to solve the following problems: the existing expansion nail installation process needs to rely on bolts and the fixation of the expansion nail and the wall fails after the bolts are removed.

[0005] The utility model is implemented as follows: a wall expansion nail comprises: a nail barrel, one side of the nail barrel is recessed inwardly, the nail barrel is provided with a three-pronged opening, the three-pronged opening is provided with three, a bullet head is arranged in the nail barrel, and the bullet head can slide along the inner wall of the nail barrel; a push rod, which can be inserted into the nail barrel, and is used to push the bullet head to move to the recessed position of the nail barrel to make one end of the nail barrel expand outwardly.

[0006] Preferably, the nail barrel is provided with an oblique hole, and the oblique hole is used to increase the friction between the nail barrel and the wall.

[0007] Preferably, the nail barrel is made of 304 stainless steel.

[0008] The wall expansion nail provided by the utility model can not only be installed with the wall, but also the push rod can be taken out to fix other expansion nails and the wall, so that the push rod can be reused, the installation efficiency of the expansion nail is improved, the operation is simple, and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 2 This is a schematic diagram of the interior of the wall expansion nail.

[0011] In the attached figure: 1-nail tube, 2-bullet head, 3-push rod, 4-three-fork, 5-oblique hole. DETAILED DESCRIPTION

[0012] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and do not limit the utility model.

[0013] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0014] See also Figure 1 and Figure 2 The utility model provides a wall expansion nail, the wall expansion nail comprising:

[0015] A nail barrel 1, one side of which is concave inwardly, is provided with a three-pronged opening 4, and three three-pronged openings 4 are provided. A bullet head 2 is arranged in the nail barrel 1, and the bullet head 2 can slide along the inner wall of the nail barrel 1; a push rod 3 can be inserted into the nail barrel 1, and is used to push the bullet head 2 to move to the concave position of the nail barrel 1 so that one end of the nail barrel 1 expands outwardly.

[0016] In this embodiment, the provision of the three-pronged opening 4 can allow the nail tube 1 to expand in three different directions, so that the fixation of the nail tube 1 and the wall is more secure.

[0017] When using the wall expansion nail, first put the nail tube 1 into the hole opened in advance in the wall, then insert the push rod 3 into the nail tube 1, knock the push rod 3, and under the push of the push rod 3, the bullet head 2 slides in the nail tube 1. When the bullet head 2 slides to the recessed part of the nail tube 1, the bullet head 2 can squeeze the nail tube 1 to expand outward, thereby realizing the expansion of the nail tube 1, and the nail tube 1 can be fixed to the wall.

[0018] like Figure 1 As shown, as a preferred embodiment of the utility model, the nail tube 1 is provided with an inclined hole 5, and the inclined hole 5 is used to increase the friction between the nail tube 1 and the wall.

[0019] The provision of the inclined hole 5 can increase the friction between the nail tube 1 and the wall, making the fixation between the nail tube 1 and the wall more secure.

[0020] like Figure 1 As shown, as a preferred embodiment of the present utility model, the material of the nail tube 1 is 304 stainless steel.

[0021] Selecting stainless steel as the material can prevent the nail barrel 1 from rusting during use, thereby extending the service life of the nail barrel 1, and at the same time make the nail barrel 1 have good ductility, ensuring that the nail barrel 1 can expand outward smoothly.

[0022] The nail tube 1 of the utility model is made of 304 stainless steel, and is provided with an oblique hole 5. A three-pronged opening 4 is provided at the bottom of the nail tube 1, and the middle of the three-pronged opening 4 is concave inwardly. It is generally used for the reinforcement of the exterior wall of a tile wall and for the invisible tile wall. A hole is opened on the tile surface, and the nail tube 1 is inserted into the wall. A stainless steel bullet head 2 is provided inside the nail tube 1. A push rod 3 is inserted into the nail tube 1 and the push rod 3 is knocked to make the three-pronged opening 4 of the nail tube 1 expand outwardly. The top of the nail tube 1 can be repaired with a tile repair paste according to the color of the tile to hide the nail tube 1 inside the tile.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
