Description

Technical Field

[0001] This utility model relates to the technical field of profile assembly, and in particular to a planar snap fastener. Background Technology

[0002] In the field of architectural decoration, traditional keel systems (such as ceilings and partitions) widely rely on various flat clips (such as straight-insertion, rotary locking, and side-sliding) to connect the decorative panels to the keel.

[0003] However, these traditional clips generally have significant drawbacks: the assembly process is cumbersome and inefficient, often requiring multiple people or specific tools; the processing and installation precision requirements for the keel and the plate are stringent, and the tolerance for error is poor; disassembly and maintenance are extremely difficult, often requiring destructive operations or disassembly of large areas of unrelated parts, which is particularly unfavorable for the inspection of concealed works; the reliability of the connection is easily affected by fatigue of elastic elements, inadequate locking or vibration, and there is a risk of loosening; operation in confined spaces is particularly inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a planar snap fastener, which aims to solve the problems in the prior art.

[0005] This utility model is implemented by including a buckle structure installed on the surface of the keel profile, wherein the four corners of the keel profile are recessed to form buckle grooves;

[0006] The snap-fit ​​structure consists of a first snap-fit ​​plate and a second snap-fit ​​plate:

[0007] The first card plate is straight, with one end bent to form a first hook and snapped into a slot, and the other end is provided with a first flange. A first locking hole is opened on the surface of the first card plate near the first flange.

[0008] The second card plate is L-shaped, with a second hook at one end that snaps into the opposite latching groove, and a second flange with a second locking hole at the other end;

[0009] The first flange and the second flange are parallel and fitted together, the hexagonal nut is limited to the second flange, and the bolt passes through the first locking hole and the second locking hole in sequence and is tightened with the hexagonal nut.

[0010] Preferably, the second card plate has two sets of limiting protrusions on one end surface near the second hook, and the distance between the two limiting protrusions is greater than the head of the hexagonal nut.

[0011] Preferably, the first keyhole is an elliptical hole, and the second keyhole is a circular hole.

[0012] Preferably, the inner angle of the bent portion of the second card plate is greater than 90°.

[0013] Preferably, the length of the parallel bonding portion of the first card plate is greater than the length of the parallel bonding portion of the second card plate.

[0014] The beneficial effects of the planar buckle disclosed in this utility model are: the planar buckle structure of this solution is simple and easy to install, which can effectively fix the keel profile. There is no need to limit the hexagonal nut during assembly, only the bolt needs to be tightened separately. In addition, it can limit the rotation of the hexagonal nut under strong vibration, which improves the reliability of locking, and improves assembly efficiency and stability.

[0027] The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] In this embodiment:

[0029] Reference Figs. 1-3 The diagram shows a preferred embodiment of the present invention.

[0030] A planar buckle of this embodiment includes a buckle structure 1 installed on the surface of a keel profile 2, wherein the four corners of the keel profile 2 are recessed to form buckle grooves 21;

[0031] The buckle structure 1 is composed of a first locking plate 11 and a second locking plate 12:

[0032] The first card plate 11 is straight, with one end bent to form a first hook 111 and snapped into the buckle groove 21, and the other end is provided with a first flange 112. A first locking hole 113 is opened on the side surface of the first card plate 11 near the first flange 112.

[0033] The second card plate 12 is L-shaped, with a second hook 121 at one end that snaps into the opposite buckle groove 21, and a second flange 122 with a second locking hole 123 at the other end;

[0034] The first flange 112 and the second flange 122 are parallel and fitted together. The hexagonal nut 131 is limited to the second flange 122. The bolt 13 passes through the first locking hole 113 and the second locking hole 123 in sequence and is tightened with the hexagonal nut 131.

[0035] The second card plate 12 has two sets of limiting protrusions 124 on one end surface near the second hook 121. The distance between the two limiting protrusions 124 is greater than the nut head of the hexagonal nut 131. The limiting protrusions 124 and the second flange 122 form a locking cavity for the hexagonal nut 131, which can be locked by a single person.

[0036] The first locking hole 113 is an elliptical hole, and the second locking hole 123 is a circular hole. This allows the first locking hole 113 with the elliptical hole to have a certain amount of redundant space when the two plates are fixed by the hexagonal nut 131 and the bolt 13, so as to avoid the locking holes of the two plates not being able to correspond due to the different specifications of the keel profile 2.

[0037] Furthermore, the inner angle of the bent portion of the second card plate 12 is greater than 90°, and the length of the parallel fitting portion of the first card plate 11 is greater than the length of the parallel fitting portion of the second card plate 12. During installation, the first card plate 11 and the second card plate 12 can more flexibly adapt to the specifications and installation position of the keel profile 2, thereby improving the convenience and applicability of installation.

[0038] During installation, the first hook 111 of the first clip 11 and the second hook 121 of the second clip 12 are first snapped into the slots 21 of the keel profile 2. Then, the sections of the first clip 11 and the second clip 12 close to the first flange 112 and the second flange 122 are made to fit parallel to each other. Next, the hexagonal nut 131 is confined within the second flange 122, and the bolt 13 is passed through the first locking hole 113 and the second locking hole 123 in sequence and tightened to the hexagonal nut 131 to complete the installation of the clip. This planar clip structure 1 is simple and easy to install. It can effectively fix the keel profile 2. There is no need to limit the hexagonal nut 131 during assembly. Only the bolt 13 needs to be tightened separately. In the event of strong vibration, the rotation of the hexagonal nut 131 is limited, which improves the reliability of locking and improves the assembly efficiency and stability.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
