The invention relates to the technical field of cement nails, in particular to a galvanized cement nail with an expansion cavity.
Background
At present, in the use process of the cement nail, although the cement nail can be nailed into a wall body, along with the prolonging of the use time, the cement nail can often loose and easily slide out of the inside of the wall body, so that the connection is failed, and then the possibility of damage to hung objects is caused.
Disclosure of Invention
The invention aims to solve the technical problems and provides a galvanized cement nail with an expansion cavity, wherein the expansion cavity is arranged on one side inside a main nail body, the main nail body is firstly knocked and embedded into a wall body, then the distance between an auxiliary nail body and the expansion cavity is adjusted, and then the auxiliary nail body is knocked again, so that the expansion cavity is deformed, the contact area between the main nail body and the wall body is increased, the firmness between the cement nail and the wall body is improved, and the problem that the conventional cement nail is easy to loosen after being used for a period of time is solved.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows: comprises a main nail body; one end of the main nail body is provided with a conical tip; an expansion cavity is arranged on one side of the inner part of the main nail body; and an arc-shaped through groove is uniformly formed in the periphery of one end of the expansion cavity.
Further optimize this technical scheme, evenly be provided with multiunit triangular barb on the external surface periphery of main nail between toper pointed end and the inflation chamber.
Further optimizing the technical scheme, the inside of the expansion cavity is provided with an auxiliary nail body; the auxiliary nail body is in threaded connection with the expansion cavity.
Further optimizing the technical scheme, one end of the upper part of the auxiliary nail body is provided with a step; the other end of the auxiliary nail body is provided with a working surface; a hexagonal slotted hole is formed in the middle of the upper part of the working surface; a plurality of groups of weight ports are uniformly arranged on the periphery of the hexagonal groove hole; and scale holes are uniformly formed in the axial direction of the upper part of the auxiliary nail body.
Compared with the prior art, the invention has the following advantages: 1. a plurality of groups of triangular barbs are uniformly arranged on the periphery of the outer surface of the main nail body between the conical tip and the expansion cavity, so that the structure is favorable for improving the firmness between the cement nail and the wall body; 2. a hexagonal slotted hole is formed in the middle of the upper portion of the working face, and the structure is favorable for adjusting the distance between the expansion cavity and the auxiliary nail body; 3. a plurality of groups of weight ports are uniformly arranged on the periphery of the hexagonal groove holes, so that the structure is favorable for reducing the overall weight of the cement nail; 4. the scale holes are uniformly formed in the axial direction of the upper portion of the auxiliary nail body, and the structure beneficially embodies the distance between the auxiliary nail body and the expansion cavity.

Fig. 2 is a cross-sectional view showing the overall structure of a galvanized cement nail having an expansion chamber.
Fig. 3 is a schematic view of a secondary nail body structure of a galvanized cement nail with an expansion cavity.
In the figure: 1. a main nail body; 2. a secondary nail body; 101. a tapered tip; 102. an expansion chamber; 103. an arc-shaped through groove; 104. three-edged barb; 201. a landing; 202. a working surface; 203. a hexagonal slotted hole; 204. a weight port; 205. and (4) a calibration hole.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The specific implementation mode is as follows: shown in combination with fig. 1-3, comprises a main nail body 1; one end of the main nail body 1 is provided with a conical tip 101; an expansion cavity 102 is arranged on one side inside the main nail body 1; arc-shaped through grooves 103 are uniformly formed in the circumference of one end of the expansion cavity 102; a plurality of groups of triangular barbs 104 are uniformly arranged on the outer surface of the main nail body 1 at the periphery between the conical tip 101 and the expansion cavity 102; the expansion cavity 102 is internally provided with an auxiliary nail body 2; the auxiliary nail body 2 is in threaded connection with the expansion cavity 102; one end of the upper part of the auxiliary nail body 2 is provided with a step 201; the other end of the auxiliary nail body 2 is provided with a working surface 202; a hexagonal slotted hole 203 is formed in the central position of the upper part of the working surface 202; a plurality of groups of weight holes 204 are uniformly arranged on the periphery of the hexagonal slotted hole 203; the upper part of the auxiliary nail body 2 is evenly provided with scale holes 205 in the axial direction.
In use, as shown in fig. 1-3, when a user uses the cement nail manufactured by the present invention, firstly, the auxiliary nail body 2 is screwed into the expansion cavity 102, the step 201 of the auxiliary nail body 2 is in contact with the main nail body 1 in the expansion cavity 102, then the tapered tip 101 of the main nail body 1 is aligned with the wall body by one hand, the hammer is operated by the other hand to strike the working surface 202 of the auxiliary nail body 2, the cement nail is driven into the wall body by the hammer, when about one fifth of the length of the main nail body 1 remains, the striking of the working surface 202 is stopped at this moment, then the hexagonal wrench is matched with the hexagonal slot 203, so as to rotate the auxiliary nail body 2, the screwing-out length of the auxiliary nail body 2 is observed by observing the scale hole 205 at the upper part of the auxiliary nail body 2, after the appropriate size is screwed out, the rotation of the auxiliary nail body 2 is stopped at this moment, a certain gap is generated between the step 201 and the main nail body 1, and the hammer is again struck on the working surface 202, because of there is the clearance inside the inflation chamber 102, arc logical groove 103 department begins atress deformation at this moment, thereby outside expansion, and then increased with the wall body between area of contact, and main nail body 1 outside periphery still evenly is provided with three-edged barb 104, thereby further increased the frictional force between cement nail and the wall body, avoided the cement nail after using a period, very easily follow the inside slippage's of wall body the condition, and for reducing the holistic weight of cement nail, under the condition of guaranteeing cement nail bulk strength, through evenly opening at auxiliary nail body 2's working face 202 upper portion periphery there is the weight hole 204, be used for lightening the whole weight of cement nail.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
