[0001] This utility model relates to the technical field of furniture accessories, specifically, to an elastic snap fastener with a clip. Background Technology

[0002] In furniture, the connection between shelves is usually achieved using elastic connectors and female bases. For example, Chinese patent document CN218151829U discloses a concealed connector for cabinet shelves, which includes a mounting cylinder embedded in the side of the shelf. The mounting cylinder has a hollow interior with a mounting cavity. The port of the mounting cavity is closed by a top cover. A connecting rod is built into the mounting cavity and can slide left and right along the mounting cavity. It also includes a connecting seat embedded in the inner side wall of the cabinet. The connecting seat has a movable groove formed through its body. The connecting rod extends into the movable groove and is fastened to the fastening groove at the lower end of the movable groove, thereby connecting the shelf to the cabinet.

[0003] However, in the aforementioned existing technology, the mounting cylinder structure requires applying glue to the holes on the side of the shelf during actual installation, or applying glue to the surface of the mounting cylinder before embedding it into the shelf, making the mounting cylinder more secure. This increases the glue smell associated with the furniture and is not environmentally friendly. Utility Model Content

[0004] In order to overcome the defects of the existing technology, this utility model provides an elastic connector for an assembled plate structure to solve the problems in the existing technology.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an elastic snap fastener with a ferrule, including an expansion kit and a plate elastic connector. The expansion kit includes an expansion sleeve with a hollow cavity inside. Movable expansion pieces are provided on both sides of the expansion sleeve. The plate elastic connector is positioned and inserted into the expansion kit so that the expansion pieces are in an open state.

[0006] In the above-mentioned elastic snap fastener with a ferrule, a gap is provided between the expansion sleeve and the expansion piece, the outer surface of the expansion piece is raised relative to the outer surface of the expansion sleeve, and a protrusion is provided on the outer wall of the expansion piece, the surface of the protrusion being inclined.

[0007] In the aforementioned elastic snap fastener with a retainer, the inner wall of the expansion piece is provided with a retaining block, and the outer wall of the elastic connector of the sheet metal is provided with a positioning hole corresponding to the retaining block.

[0008] In the aforementioned elastic snap fastener with a ferrule, the elastic connecting piece of the sheet metal includes a main body, which is inserted into a hollow cavity. The positioning hole is located on the outer wall of the main body, and a retractable connecting rod is provided at one end of the main body.

[0009] In the aforementioned elastic snap fastener with a ferrule, the main body includes a base and a cover seat. Both the base and the cover seat have spring cavities. A stud is provided on the base. The inner wall of the cover seat near the stud end has an internal thread. The stud is threadedly connected to the internal thread. The connecting rod is inserted into the base. A spring is installed in the spring cavity, and one end of the spring abuts against the connecting rod.

[0010] In the aforementioned elastic snap fastener with a ferrule, the positioning hole is formed on the outer wall of the cover seat, and a limiting ring is provided on the outer wall of the base away from the cover seat, the diameter of the limiting ring being larger than the hollow cavity.

[0011] The beneficial effects of this utility model are that, after the expansion kit is embedded in the shelf, the elastic connector of the board is inserted into the expansion sleeve, so that the expansion piece is expanded, thereby making the expansion sleeve firmly installed in the shelf. At the same time, the elastic connector of the board is positioned and installed in the expansion sleeve, so that the entire elastic snap fastener is more firmly installed in the shelf. No glue is needed during the installation process, which is more environmentally friendly during assembly and can also reduce the glue smell of furniture. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] Combination Figures 1 to 5 The illustrated elastic snap fastener with a retainer includes an expansion kit 1 and a board elastic connector 2. The expansion kit 1 includes an expansion sleeve 3 with a hollow cavity 6 inside. Movable expansion tabs 4 are provided on both sides of the expansion sleeve 3. The board elastic connector 2 is positioned and inserted into the expansion kit 1, causing the expansion tabs 4 to be in an expanded state. In this embodiment, after the expansion kit 1 is embedded into the shelf, the board elastic connector 2 is inserted into the expansion sleeve 3, causing the expansion tabs 4 to expand, thereby making the expansion sleeve 3 firmly installed in the shelf. At the same time, the board elastic connector 2 is positioned and installed in the expansion sleeve 3, making the entire elastic snap fastener more secure in the shelf. The installation process does not require the use of glue, making the assembly more environmentally friendly and reducing the glue smell of the furniture.

[0020] In this embodiment, a gap 5 is provided between the expansion sleeve 3 and the expansion piece 4. The outer surface of the expansion piece 4 is raised relative to the outer surface of the expansion sleeve 3. A protrusion 7 is provided on the outer wall of the expansion piece 4. The surface of the protrusion 7 is inclined. The inclined surface is inclined from the insertion direction of the plate elastic connector 2 to the opposite direction, so that after the expansion sleeve 3 is inserted into the mounting hole of the layer plate, it can prevent the expansion sleeve 3 from detaching in the opposite direction. One end of the expansion piece 4 is connected to the expansion sleeve 3, and a part of the edge of the other end forms a gap 5 with the expansion sleeve 3, so that the expansion piece 4 can swing away from the connection part with the expansion sleeve 3. Specifically, after inserting the plate elastic connector 2, the expansion piece 4 swings outward and expands.

[0021] In this embodiment, the inner wall of the expansion piece 4 is provided with a locking block 8, and the outer wall of the plate elastic connector 2 is provided with a positioning hole 10 corresponding to the locking block 8. After the plate elastic connector 2 is inserted into the expansion sleeve 3, the expansion piece 4 also has the function of pressing the plate elastic connector 2 in the opposite direction. At the same time, after the locking block 8 is engaged in the positioning hole 10, the plate elastic connector 2 is firmly engaged in the expansion sleeve 3, which can prevent the plate elastic connector 2 from falling off, making the whole more solid.

[0022] Specifically, the elastic connector 2 of the sheet metal in this embodiment includes a main body 9, which is inserted into the hollow cavity 6. The positioning hole 10 is provided on the outer wall of the main body 9. One end of the main body 9 is provided with a telescopic connecting rod 12. The main body 9 includes a base 13 and a cover seat 14. Both the base 13 and the cover seat 14 are provided with spring cavities 16. The base 13 is provided with a stud 15. The inner wall of the cover seat 14 near the stud 15 is provided with an internal thread. The stud 15 is threadedly connected to the internal thread. The connecting rod 12 is inserted into the base 13. A spring is installed in the spring cavity 16, and one end of the spring abuts against the connecting rod 12. This allows the main body 9 to be assembled by threaded connection between the base 13 and the cover seat 14, which facilitates the replacement of the internal spring or assembly.

[0023] It is worth noting that in this embodiment, the positioning hole 10 is opened on the outer wall of the cover seat 14, and a limiting ring 11 is provided on the outer wall of the base 13 away from the cover seat 14. The diameter of the limiting ring 11 is larger than that of the hollow cavity 6. This makes the installation more convenient and does not require glue fixation.

[0024] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
