Description

Technical Field

[0001] This utility model belongs to the technical field of dormitory living tools, and in particular relates to a hidden frame snap-fit ​​connection mechanism for a steel structure dormitory bed. Background Technology

[0002] As a fundamental infrastructure of campus life, the safety, stability, durability, and space utilization efficiency of student dormitory beds are of paramount importance. Currently, mainstream student dormitory beds generally use cold-rolled thin-walled steel, represented by square and rectangular steel tubes, as the bed frame material. In terms of structural connection methods, the industry widely relies on a traditional snap-fit ​​connection method, which is characterized by: specific holes being made above the vertical posts, and special snap-fit ​​plates being welded to the ends of the horizontal beams. The bed frame is assembled and fixed by inserting the snap-fits into the holes in the posts.

[0003] While this technical solution achieves basic load-bearing functionality to a certain extent, its inherent design flaws are also quite prominent. The connection structure is completely exposed after assembly, which not only detracts from the overall aesthetics of the bed, giving it a rough and rudimentary appearance, but also poses safety risks. Its "hook-on" connection principle results in weak resistance to pull-out and torsion, posing a risk of loosening under long-term use or sudden loads. Furthermore, the insufficient rigidity of the connection point easily causes the bed to wobble and make abnormal noises under stress, affecting its stability. The welded clips themselves may also become structural weak points due to welding quality or stress concentration, limiting the overall durability and lifespan of the product. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a concealed frame snap-fit ​​connection mechanism for steel structure dormitory beds, thereby solving the technical problems of aesthetic, safety, and stability defects caused by exposed connection structures.

[0005] The objective of this utility model can be achieved through the following technical solutions: A concealed frame snap-fit ​​connection mechanism for a steel structure dormitory bed includes a first crossbar, a second crossbar, and a column. The mechanism also includes a first snap-fit ​​part and a second snap-fit ​​part. The first snap-fit ​​part is located at the end of the first crossbar, and the cross-section of the first snap-fit ​​part is U-shaped. The column has a sleeve hole through which the first snap-fit ​​part extends into the column. The second snap-fit ​​part is located at the end of the second crossbar, and the second snap-fit ​​part consists of two sets of strip-shaped structures. The column has two sliding grooves through which the second snap-fit ​​part extends into the column. The strip-shaped structure of the second snap-fit ​​part has two sets of slots, which fit onto the vertical surface of the first snap-fit ​​part.

[0006] As a preferred embodiment of the above technical solution, the length of the groove is greater than the width of the strip structure on the second locking part, and the second locking part moves along the length direction of the groove.

[0007] As a preferred embodiment of the above technical solution, the end faces of both the first and second crossbars abut against the outer surface of the column.

[0008] As a preferred embodiment of the above technical solution, the first snap-fit ​​part is provided with two sets of symmetrical limiting plates. The two sets of symmetrical limiting plates respectively restrict the two sets of strip structures on the second snap-fit ​​part. The strip structures are snapped between the two symmetrical limiting plates. The top of the limiting plate is provided with an arc portion, and the bottom of the slot is provided with an oblique opening.

[0009] As a preferred embodiment of the above technical solution, the column is provided with baffle one, baffle two and baffle three respectively. Baffle one and baffle two are used to restrict the movement of the locking part two toward the horizontal bar one, and baffle three is used to restrict the movement of the locking part one toward the horizontal bar two.

[0010] As a preferred embodiment of the above technical solution, a locking component is installed at the slide groove. The locking component includes a connecting plate and two wedge-shaped extrusion plates. The extrusion plates are disposed on one side of the connecting plate. The extrusion plates pass through the slide groove and are used to fill the exposed part of the slide groove. The bottom of the extrusion plates abuts against the top of the crossbar.

[0011] The beneficial effects of this utility model are as follows: 1. In this utility model, the snap-on connection structure is hidden in the column. Through cross-shaped snap-fit, it can achieve quick and firm tool-free disassembly and assembly, while ensuring high structural strength and good stability of the connection point. Most importantly, it can completely or mostly hide the connection structure inside the profile or under the connection surface, completely eliminating the aesthetic and safety problems caused by exposed fasteners, and improving the overall quality and user experience of the dormitory bed. 2. In this utility model, the mutual restriction between the vertical surface of the first snap-fit ​​part and the strip structure of the second snap-fit ​​part enables the first snap-fit ​​part and the second snap-fit ​​part to be fixed to each other, thereby improving the stability of the first snap-fit ​​part and the second snap-fit ​​part after assembly; furthermore, the movement of the second snap-fit ​​part is restricted by the first baffle and the movement of the first snap-fit ​​part is restricted by the third baffle, thereby further improving the stability of the first snap-fit ​​part and the second snap-fit ​​part after assembly. 3. In this utility model, after assembling the first and second snap-fit ​​parts, the locking member is placed in the slide groove, so that the two extrusion plates are respectively inserted into the two sets of slide grooves. Then the connecting plate is hammered to fill the exposed part of the slide groove with the extrusion plate, and the bottom of the extrusion plate abuts against the top of the second crossbar. This can further improve the stability of the first and second snap-fit ​​parts after assembly. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1-4 As shown, a hidden frame snap-fit ​​connection mechanism for a steel structure dormitory bed includes a first crossbar 1, a second crossbar 3, and a column 5. The mechanism also includes a first snap-fit ​​part 2 and a second snap-fit ​​part 4. The end of the first crossbar 1 is provided with a first snap-fit ​​part 2, which has a U-shaped cross section. The column 5 has a sleeve hole 51, through which the first snap-fit ​​part 2 extends into the column 5. The end of the second crossbar 3 is provided with a second snap-fit ​​part 4, which consists of two sets of strip-shaped structures. The column 5 has two sliding grooves 52, through which the second snap-fit ​​part 4 extends into the column 5. The strip-shaped structure of the second snap-fit ​​part 4 has two sets of slots 41, which fit onto the vertical surface of the first snap-fit ​​part 2.

[0016] The length of the groove 52 is greater than the width of the strip structure on the second snap-fit ​​part 4, and the second snap-fit ​​part 4 moves along the length direction of the groove 52.

[0017] The end faces of both crossbar 1 and crossbar 2 abut against the outer surface of column 5.

[0018] The first snap-fit ​​part 2 is provided with two sets of symmetrical limiting plates 21. The two sets of symmetrical limiting plates 21 respectively restrict the two sets of strip structures on the second snap-fit ​​part 4. The strip structures are snapped between the two symmetrical limiting plates 21. The top of the limiting plate 21 is provided with an arc part 211, and the bottom of the slot 41 is provided with a bevel 411.

[0019] In practical application, the first crossbar 1 serves as the load-bearing bar at the head and foot of the bed, while the second crossbar 3 serves as the load-bearing bar at the front and rear of the bed. During installation, the first snap-fit ​​part 2 at the end of the first crossbar 1 is inserted into the upright 5 through the sleeve hole 51. Then, the second snap-fit ​​part 4 at the end of the second crossbar 3 is inserted into the upright 5 through two sets of sliding grooves 52. Next, the second crossbar 3 is moved down, causing the second snap-fit ​​part 4 to move down as well. This allows the slot 41 on the second snap-fit ​​part 4 to snap onto the vertical surface of the first snap-fit ​​part 2, and the second snap-fit ​​part 4 is restrained by two sets of symmetrical limiting plates 21, thus completing the assembly of the first crossbar 1, the second crossbar 3, and the upright 5. The entire assembly process requires no welding or bolt connections, and the snap-fit ​​structure is hidden inside the upright 5. While meeting the safety and functional requirements of the dormitory bed, this simplifies the assembly process, improves installation efficiency, and enhances the appearance of the bed. The locking parts 1 and 2, through their overlapping and mutual support design, form a mechanical self-locking structure after insertion, which has good tensile and shear resistance, ensuring the stability and safety of the dormitory bed during use; at the same time, the end faces of the crossbars 1 and 2 abut against the outer surface of the upright 5, thereby further improving the stability and strength of the locking parts 1 and 2. The cooperation between the arc portion 211 and the beveled opening 411 allows the second snap-fit ​​portion 4 to be smoothly snapped onto the first snap-fit ​​portion 2 and into the limiting plate 21, thereby further improving installation efficiency.

[0020] Furthermore, the column 5 is provided with baffle 1 53, baffle 2 54 and baffle 3 55 respectively. Baffle 1 53 and baffle 2 54 are used to restrict the movement of the locking part 2 4 towards the horizontal bar 1, and baffle 3 55 is used to restrict the movement of the locking part 2 towards the horizontal bar 2 3.

[0021] In practical application, this embodiment uses the mutual constraint between the vertical surface of the first snap-fit ​​part 2 and the strip structure of the second snap-fit ​​part 4 to fix the first snap-fit ​​part 2 and the second snap-fit ​​part 4 to each other, thereby improving the stability of the assembled first snap-fit ​​part 2 and the second snap-fit ​​part 4; furthermore, the movement of the second snap-fit ​​part 4 is restricted by the first baffle 53 and the second baffle 54, and the movement of the first snap-fit ​​part 2 is restricted by the third baffle 55, thereby further improving the stability of the assembled first snap-fit ​​part 2 and the second snap-fit ​​part 4.

[0022] Furthermore, a locking element 6 is installed at the slide groove 52. The locking element 6 includes a connecting plate 61 and two wedge-shaped extrusion plates 62. The extrusion plates 62 are disposed on one side of the connecting plate 61. The extrusion plates 62 pass through the slide groove 52 and are used to fill the exposed part of the slide groove 52. The bottom of the extrusion plates 62 abuts against the top of the crossbar 2 3.

[0023] In practical application, after assembling the first snap-fit ​​part 2 and the second snap-fit ​​part 4, the locking member 6 is placed at the slide groove 52, so that the two extrusion plates 62 extend into the two sets of slide grooves 52 respectively. Then, the connecting plate 61 is hammered to fill the exposed part of the slide groove 52 with the extrusion plates 62, and the bottom of the extrusion plates 62 abuts against the top of the crossbar 3. This can further improve the stability of the first snap-fit ​​part 2 and the second snap-fit ​​part 4 after assembly.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
