Description

Technical Field

[0001] The utility model relates to the technical field of home decoration, in particular to a keel leveling and fixing structure. Background Art

[0002] When dry-hanging wall panels are installed on indoor walls, it is necessary to first fix the keel to the wall with a number of expansion screws, and then insert a number of inclined wedges between the keel and the wall from both sides to level the keel. During the leveling process, it is necessary to repeatedly adjust the depth of the expansion screws locked into the wall. This leveling method not only has a very low leveling efficiency, but also the repeated rotation of the expansion screws can easily reduce the reliability of the connection with the wall. In addition, the inclined wedges below are also easy to fall off during use, thereby affecting the stability of the wall panel installation structure. Utility Model Content

[0003] The utility model aims to provide a keel leveling and fixing structure which is easy to level and has high reliability.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A keel leveling and fixing structure comprises a keel and a plurality of wall nails for fixing the keel to a wall surface; the keel has a through hole for the wall nail to pass through, the wall nail comprises a cylindrical body, the front section of the body is a tapped section, and the rear section of the body is a threaded section passing through the through hole, the rear end surface of the body has a rotating portion, and also comprises two nuts that cooperate with the threaded section and are respectively located on the inner and outer sides of the keel.

[0006] In a preferred embodiment, the threads of the threaded section extend to a rear end edge of the body.

[0007] In a preferred embodiment, the outer side surface of the keel away from the wall has a groove along its length direction, the through hole is arranged in the groove, and the outer end surfaces of the wall nail and the nut do not exceed the outer side surface of the keel.

[0008] In a preferred embodiment, washers are provided on one side of the two nuts close to the keel.

[0009] In a preferred embodiment, the rotating portion is a hexagonal socket.

[0010] The beneficial effect of this solution is that during installation, firstly, the through-hole position of each wall nail corresponding to the keel is locked on the wall surface, then one of its nuts is matched with the threaded section, and then the through-hole of the keel is inserted into each wall nail, and then the other nut is matched with the threaded section. At this time, the flatness of the keel can be adjusted by rotating one of its nuts, and after leveling, the keel can be locked by rotating the other nut. Compared with the existing keel leveling and fixing structure, this solution does not need to repeatedly adjust the depth of the wall nail locked into the wall during the leveling process, so it will not affect the reliability of the combination of the wall nail and the wall surface, and there is no need to insert a large number of wedges for leveling, which not only simplifies the structure, but also significantly improves the installation efficiency, and there is no risk of the wedge falling off, and the reliability is higher. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0012] Figure 1 It is a schematic cross-sectional structure diagram of the keel leveling and fixing structure in the embodiment. DETAILED DESCRIPTION

[0013] The utility model is further described below in conjunction with the accompanying drawings:

[0014] refer to Figure 1 A keel leveling fixing structure of the present embodiment includes a keel 1 and a plurality of wall nails 2 for fixing the keel 1 to a wall surface; the keel 1 has a through hole 11 for the wall nail 2 to pass through, the wall nail 2 includes a cylindrical body, the front section of the body is a tapping section 21, and the rear section of the body is a threaded section 22 passing through the through hole 11, the rear end surface of the body has a rotating portion 23, the rotating portion 23 of the present embodiment is preferably a hexagonal socket, and also includes two nuts 3 that cooperate with the threaded section 22 and are respectively located on the inner and outer sides of the keel 1.

[0015] During installation, firstly, each wall nail 2 is locked to the wall surface at the position corresponding to the through hole 11 of the keel 1, and then one of its nuts 3 is matched with the threaded section 22, and then the through hole 11 of the keel 1 is inserted into each wall nail 2, and then the other nut 3 is matched with the threaded section 22. At this time, the flatness of the keel 1 can be adjusted by rotating one of its nuts 3. After leveling, the keel 1 can be locked by rotating the other nut 3. Compared with the existing keel 1 leveling and fixing structure, this solution does not need to repeatedly adjust the depth of the wall nail 2 locked into the wall surface during the leveling process, so it will not affect the reliability of the combination of the wall nail 2 and the wall surface, and there is no need to insert a large number of wedges for leveling, which not only simplifies the structure, but also significantly improves the installation efficiency, and there is no risk of the wedge falling off, and the reliability is higher.

[0016] In a preferred embodiment, the threads of the threaded section 22 of this embodiment extend to the rear edge of the body. On the one hand, it is convenient for the nut 3 to penetrate the wall stud 2 from the rear end for threaded engagement, and on the other hand, the rear end face of the wall stud 2 does not exceed the end face of the outer nut 3, so as to reduce the thickness of the keel 1 during installation.

[0017] In a preferred embodiment, the outer side of the keel 1 away from the wall surface has a groove 12 along its length direction, the through hole 11 is arranged in the groove 12, and the outer end faces of the wall nail 2 and the nut 3 do not exceed the outer side of the keel 1. The keel 1 is provided with the groove 12, which can not only be used to fix with the wallboard through the connecting buckle, but also can make the wall nail 2 and the nut 3 not exceed its outer side, so as to facilitate the wallboard to be fitted and fixed to the outer side of the keel 1.

[0018] In a preferred embodiment, washers 31 are provided on one side of the two nuts 3 of this embodiment close to the keel 1. The washers 31 can prevent the nuts 3 from loosening and improve the reliability of installation.

[0019] The above description does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
