Description

Technical Field

[0001] The utility model belongs to the technical field of frame docking and corner splicing, and particularly relates to a profile frame corner splicing buckle. Background Art

[0002] Various kinds of fasteners such as hardware and plastics are used in the frame splicing of profiles. Generally, hardware parts, plastic parts, etc. are inserted into the inner cavity of the frame, and then locked and fixed with screws, or adhered with glue. However, the above fixing methods have the following defects: 1. Gaps will appear in the assembled frame, and it is difficult to maintain a ninety-degree angle, affecting the appearance; 2. When making the frame splicing, one end of a frame needs to be inserted into a corner fitting first. After locking one screw, the second frame bar is inserted. It is necessary to use tools to align it before locking the second screw. Four corner fittings and eight screws are required for each frame; or glue is applied to the corner fitting and then the frame is installed. The back glued with glue cannot be disassembled. When splicing the frame in the above way, not only the process is cumbersome, time-consuming and consumable, but also the production efficiency is low. Content of the Utility Model

[0003] The purpose of the utility model is to provide a profile frame corner splicing buckle to solve the above technical problems.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a profile frame corner splicing buckle, including a corner splicing buckle body, the corner splicing buckle body is composed of two mirror-symmetrical installation parts, the two installation parts are vertically arranged, installation grooves are respectively opened on the two installation parts, the installation grooves are respectively used for connecting a horizontal profile and a vertical profile, the installation grooves are obliquely opened, a guiding insertion point is formed on the inner edge of the installation groove, and a fixed balance point is arranged on the outer edge of the installation groove.

[0005] Further, ramp-shaped tooth marks are arranged on the outer surfaces around the installation parts, and the ramp-shaped tooth marks are in the shape of barbs.

[0006] Further, the guiding insertion point is in the shape of an inclined sharp angle, and the length of the guiding insertion point is greater than that of the outer fixed balance point.

[0007] Further, the fixed balance point protrudes from the inclined opening of the installation groove, and the inside of the fixed balance point is hollow and communicated with the installation groove.

[0008] Further, an outer angle bevel is opened at the outer angle of the corner splicing buckle body.

[0009] Further, an avoidance space is opened at the inner angle of the corner splicing buckle body.

[0010] Further, the corner splicing buckle body is in a hollow shape inside.

[0011] Through the above technical solution, compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. By setting two mutually perpendicular mounting parts, and opening mounting grooves on the mounting parts, and respectively providing guide insertion points and fixed balance points on the inner and outer sides of the mounting groove, it becomes a convenient and quick corner buckle. When in use, the mounting part on one side of the corner buckle body is inserted into the frame bar through the mounting groove. Since the guide insertion point is longer than the extended side, the guide insertion point can play a guiding role during the insertion process of the mounting part, so that the insertion will not be offset. The above-mentioned plug-in method reduces the cumbersomeness of framing, saves time and effort, and thus improves production efficiency.

[0013] 2. By providing outer corner bevels and avoidance positions at the inner and outer angles of the corner buckle body respectively, gaps in the assembled frame can be avoided, and the angle is difficult to maintain at a 90-degree angle, which affects the appearance of the technical problem. Specifically, the outer corner bevel avoids the right angle of the frame strip after the corners are squeezed tightly, and the profile will not be unable to be assembled in place due to the right angle pressing against the inner corner of the profile during splicing; the inner corner avoidance position avoids the residual edge of the cutting line when the profile is squeezed into place, so that the entire frame is square and seamless after the feet are assembled.

[0014] 3. By providing sloped tooth marks on the outer surface around the installation part, when the corner buckle body is inserted into the profile, the sloped tooth marks will clamp the frame groove and act as a reverse hook, making it difficult to fall off and loosen.

[0025] As Figures 1-3 shown in the first embodiment of the present utility model: a profile frame corner splicing buckle, including a splicing buckle body 1. The splicing buckle body 1 is composed of two mirror-symmetrical installation parts 2. The two installation parts 2 are vertically arranged. Installation grooves 3 are opened on both of the two installation parts 2. The installation grooves 3 are respectively used to connect the horizontal profile and the vertical profile. The installation grooves 3 are inclined openings. A guiding insertion point 101 is formed on the inner edge of the installation groove 3, and a fixed balance point 102 is provided on the outer edge of the installation groove 3.

[0026] By setting two mutually perpendicular mounting parts 2 and opening mounting grooves 3 on both mounting parts 2, the openings of the mounting grooves 3 are inclined. Guide insertion points 101 and fixed balance points 102 are respectively provided on the inner and outer sides of the openings of the mounting grooves 3, making it a convenient and fast corner splicing buckle. When in use, first insert the mounting part 2 on one side of the corner splicing buckle body 1 into the frame bar of the profile through the mounting groove 3. Since the guide insertion point 101 is longer than the outer extension side, the guide insertion point 101 can play a guiding role during the insertion process of the mounting part 2 into the frame bar, ensuring that the insertion does not deviate. Then insert the mounting part 2 on the other side into the frame bar in the same way to complete the vertical fixation of the horizontal profile and the vertical profile. By means of the above plugging method, the complexity of the profile during frame splicing is reduced, saving time and effort and improving the overall production efficiency.

[0027] As Figures 1-3 shown: Slope-shaped tooth marks 201 are provided on the outer surfaces around the mounting part 2. The slope-shaped tooth marks 201 are barbed. By providing slope-shaped tooth marks 201 on the outer surfaces around the mounting part 2, when the corner splicing buckle body 1 is inserted into the profile, the slope-shaped tooth marks 201 will clamp the frame groove of the profile to play a role of a reverse hook, making it not easy to fall off and loosen.

[0028] As Figure 2 shown: The guide insertion point 101 is in the shape of an inclined sharp angle, and the length of the guide insertion point 101 is greater than that of the outer extension fixed balance point 102.

[0029] As Figures 1-2 shown: The fixed balance point 102 protrudes from the inclined opening of the mounting groove 3. The fixed balance point 102 is hollow inside and is connected to the mounting groove 3. The fixed balance point 102 includes an outer extension side and two side edges perpendicular to the outer extension side. The outer extension side and the two side edges enclose a fixed balance frame together. The fixed balance frame is connected to the mounting groove 3, and one end of the other side edge is connected to the inclined notch of the mounting groove 3.

[0030] As Figure 2 shown: An outer angle bevel 4 is provided at the outer angle of the corner splicing buckle body 1. After the frame is assembled, this bevel avoids hitting the inner angle of the profile frame.

[0031] As Figure 2 shown: An avoidance space 5 is provided at the inner angle of the corner splicing buckle body 1. The inner angle avoidance space is used to avoid the burrs remaining after the frame bar is cut when the corner buckle is installed during frame splicing, making the frame assembly deeper and tighter.

[0032] By respectively providing an outer corner bevel 4 and a avoiding space 5 at the inner and outer angles of the corner buckle body 1, it is avoided that there will be gaps in the assembled frame, and the angle is difficult to maintain at a 90-degree angle, which affects the appearance of the technical problem. Specifically, the outer corner bevel 4 avoids the right angle of the frame strip after the corners are squeezed tightly, and the profile will not be unable to be assembled in place due to the right angle pressing against the inner corner of the profile during splicing; the inner corner avoiding space 5 avoids the residual edge of the cutting line when the profile is squeezed into place, so that the entire frame is square and seamless after the feet are assembled.

[0033] The main body 1 of the corner buckle is hollow inside. The main body 1 of the corner buckle is designed according to various profiles. The profiles are hollow inside and have different thicknesses.

[0034] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
