Description

Technical Field

[0001] This utility model relates to the field of home decoration and furnishing technology, and in particular to a concealed frame installation structure. Background Technology

[0002] In the fields of architecture, interior decoration and furniture manufacturing, frame structure, as the core component for support and connection, has long been a typical design that combines functionality and visibility. Concealed frame structure, as the core supporting technology for achieving a boundless visual effect, is traditionally achieved by adhesive bonding or welding.

[0003] The aforementioned existing technical solutions have the following drawbacks: the adhesive backing is not strong enough to support excessive weight, and the high temperature of welding will damage the frame structure, causing it to deform. Utility Model Content

[0004] The purpose of this invention is to provide a concealed frame installation structure to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A concealed frame mounting structure, comprising,

[0007] A frame, the frame comprising a first support, a second support, and a third support;

[0008] Multiple first brackets are provided. The cross-section of the first bracket is rectangular. The top and bottom right sides of the first bracket are provided with left-right through clearance holes. The top and bottom rear sides of the first bracket are provided with front-back through clearance holes. Multiple through positioning holes are provided around the clearance holes on the right and rear sides of the first bracket.

[0009] The number of the second brackets is the same as the number of the first brackets. The left and right sides of the second brackets are fixedly connected to the first brackets. The bottom left and right sides of the interior of the second brackets are provided with blocks. The cross-section of the second bracket is rectangular. Both the second bracket and the first bracket are hollow inside.

[0010] The number of the third supports is the same as the number of the first supports. The third supports and the second supports have the same structure. The front and rear sides of the third supports are connected to the first supports.

[0011] A fixing module is provided, which is located inside the second and third supports and is used to fix the first, second, and third supports.

[0012] By adopting the above technical solution, the first and second supports and the first and third supports are fixedly connected by a fixed module, which hides the installation marks and can bear a large weight without causing deformation of the first, second and third supports.

[0013] In a further embodiment, the fixing module includes:

[0014] The fixing block has a non-through mounting groove at its right end, and a through mounting hole at the center of its left end. The mounting hole communicates with the mounting groove. Multiple positioning posts corresponding to positioning holes are provided around the mounting hole on the left side of the fixing block. The positioning posts are used to position the first bracket.

[0015] The fixing block has a through hole on the left side of its bottom end, which is connected to the mounting groove. A cylinder is fitted inside the through hole. The bottom end of the cylinder has an integrally formed frustum. The bottom end of the fixing block has a countersunk hole corresponding to the frustum. The countersunk hole is coaxial with the through hole. The cylinder is used to restrict the movement of the second and third supports.

[0016] In a further embodiment, the diameter of the frustum is larger than the diameter of the cylinder.

[0017] In a further embodiment, it also includes,

[0018] A rivet, wherein the bottom end of the rivet passes through the mounting hole and the clearance hole in the mounting groove and is fixedly connected to the first bracket.

[0019] In a further embodiment, the length of the rivet is less than the width of the first bracket.

[0020] In a further embodiment, the cross-section of the fixing block is smaller than the cross-section of the second bracket.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. By setting an integrally formed frustum at the bottom of the cylinder, with the diameter of the frustum being larger than that of the cylinder, the frustum can be inserted into the countersunk hole when the fixing block is inverted, and will not leave the through hole. When the fixing block is restored to its original shape, the stop block will block the cylinder and the frustum.

[0023] 2. By setting the positioning post of the fixing block and the positioning hole on the first bracket, the mounting hole of the fixing block and the clearance hole of the first bracket can be aligned through the positioning post and the positioning hole, so that the rivet can be fixedly connected through the mounting hole and the clearance hole, thus fixing the fixing block and the first bracket.

[0032] Example 1:

[0033] like Figures 1-3As shown, a concealed frame installation structure includes a frame 1 and a fixing module 2. The frame 1 includes a first bracket 11, a second bracket 12, and a third bracket 13, with four of each. The first bracket 11 has a rectangular cross-section. The top and bottom right sides of the first bracket 11 have through-holes, and the top and bottom rear sides of the first bracket 11 have through-holes. Multiple through-holes (two in total) are located around the perimeter of the through-holes on the right and rear sides of the first bracket 11. The positioning holes are located at the top of the through-holes. The second support 12 is fixedly connected to the first support 11 on both the left and right sides by fixing modules 2. The bottom of the second support 12 is provided with blocks 121 on both the left and right sides. The cross-section of the second support 12 is rectangular. Both the second support 12 and the first support 11 are hollow inside. The third support 13 has the same structure as the second support 12. The front and rear sides of the third support 13 are fixedly connected to the first support 11 by fixing modules 2. The fixing modules 2 are located inside the second support 12 and the third support 13. The fixing modules 2 are used to fix the first support 11, the second support 12 and the third support 13.

[0034] The fixing module 2 includes a fixing block 21 and a cylinder 22. The right end of the fixing block 21 has a non-through mounting groove running from right to left. The center of the left end of the fixing block 21 has a through mounting hole that connects to the mounting groove. Around the left side of the mounting hole, there are two positioning posts 211 corresponding to positioning holes. These positioning posts 211 cooperate with the positioning holes to position the first bracket 11. The bottom left side of the fixing block 21 has a through hole that connects to the mounting groove. A cylinder 22 is fitted inside the through hole, and the bottom end of the cylinder 22 has an integrally formed cylindrical... The platform has a countersunk hole at the bottom of the fixing block 21 corresponding to the frustum. The countersunk hole and the through hole are coaxial. The cylinder 22 is used to restrict the movement of the second support 12 and the third support 13. The diameter of the frustum is larger than the diameter of the cylinder 22. A rivet 3 is provided in the mounting groove. The rivet 3 passes through the mounting hole and the clearance hole at the bottom of the mounting groove and is fixedly connected to the first support 11, so that the fixing block 21 and the first support 11 are fixedly connected by the rivet 3. The length of the rivet 3 is less than the width of the first support 11. The cross-section of the fixing block 21 is smaller than the cross-section of the second support 12, so that the fixing block 21 can rotate inside the second support 12.

[0035] Specific implementation process: By aligning the positioning pin 211 of the fixing block 21 with the positioning hole of the first bracket 11, the mounting hole of the fixing block 21 is aligned with the clearance hole of the first bracket 11. Then, the rivet 3 is passed through the mounting hole and clearance hole from the bottom end of the mounting groove and fixedly connected to the first bracket 11, thus fixing the first bracket 11 and the fixing block 21. The first bracket 11 and the fixing block 21 are rotated together by 180°. Under the action of gravity, the frustum at the bottom of the cylinder 22 enters the countersunk hole at the bottom of the fixing block 21. The fixing block 21 is then placed inside the second bracket 12. Since the frustum is located inside the countersunk hole, it will not interfere with the stop block 121 inside the second bracket 12. The first bracket 11 and the fixing block 21 are then rotated. The 180° rotation returns the first bracket 11 and the fixing block 21 to their original positions. Under the influence of gravity, the cylinder 22 and the frustum fitted inside the through hole of the fixing block 21 fall to the end of the second bracket 12 stop block 121 away from the opening. The stop block 121 prevents the fixing block 21 from moving out of the second bracket 12. The second bracket 12 and the first bracket 11 are fixedly connected. The third bracket 13 is installed in the same way as the second bracket 12. The third bracket 13 is fixedly connected to the first bracket 11 through the fixing module 2. The first bracket 11, the second bracket 12 and the third bracket 13 are installed one by one. The four first brackets 11, the four second brackets 12 and the four third brackets 13 together form a frame 1. The frame 1 has no installation marks on its surface.

[0036] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0037] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
