Description

Technical Field

[0001] This utility model relates to the field of fastener technology, and in particular to a furniture connector. Background Technology

[0002] Currently, people have increasingly higher requirements for the aesthetics of furniture, thus increasing the demand for concealed connectors. During furniture assembly, simply drill holes in the side wall of the cabinet, hammer the concealed connectors into these holes, and drill corresponding grooves on the side of the support plate, aligning the grooves with the connection points of the concealed connectors. Then, push the support plate into the cabinet to complete the installation. This method hides the connection holes, making the furniture appear almost seamless and more natural and aesthetically pleasing. Furthermore, it makes disassembly and assembly much easier.

[0003] However, the hidden connectors and the side wall holes of the cabinet are usually connected by an interference fit. Moreover, furniture is generally made of wood. After long-term use or repeated removal and installation of the tray from the cabinet, the holes on the cabinet may be enlarged, causing the tray to loosen and affecting the user experience.

[0004] The technical problem that this utility model needs to solve is: how to improve the connection stability between the connector and the side wall of the cabinet. Utility Model Content

[0005] The main purpose of this utility model is to provide a furniture connector. By providing an embedding block and setting a column on the embedding block, after drilling a hole in the side wall of the cabinet, the expansion column of the base is inserted into the hole, and then the column of the embedding block is inserted into the through hole of the expansion column, so that the arc-shaped piece of the expansion column opens outward, thereby fixing the arc-shaped piece on the hole of the cabinet, increasing the clamping force between the arc-shaped piece and the hole of the cabinet, thereby improving the connection stability between the connector and the side wall of the cabinet.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A furniture connector includes a base and an insert block; the base has a connecting portion on the side facing the insert block that connects to a groove of an external support plate, the connecting portion having a receiving groove; the base has an expansion column on the side away from the insert block, formed by at least two arc-shaped pieces, the expansion column having a through hole penetrating the base and the expansion column, the through hole extending axially along the axial direction of the expansion column, the through hole gradually decreasing in size in the direction away from the insert block; the insert block is located within the receiving groove, the side of the insert block facing the base has a column, the column being at least partially inserted into the through hole.

[0008] Preferably, the connecting portion consists of two elastic blocks arranged opposite to each other and spaced apart along the width direction of the substrate; the receiving groove is the gap between the two elastic blocks.

[0009] Preferably, both elastic blocks are provided with a first through groove, the length direction of which extends along the arrangement direction of the two elastic blocks; the embedded block is provided with a second through groove, the length direction of which extends along the arrangement direction of the two elastic blocks, the second through groove and the first through groove are directly opposite each other along the arrangement direction of the two elastic blocks, and the second through groove and the first through groove cooperate to allow the peripheral tool to pass through the first through groove and the second through groove to pry open the embedded block.

[0010] Preferably, the outer wall of the elastic block at the end away from the base is provided with a positioning boss, and the side of the positioning boss away from the base is provided with a guide slope.

[0011] Preferably, the embedded block has elastic sheets on both sides along its length direction, the elastic sheets are arranged obliquely along the arrangement direction of the substrate and the embedded block, and the free end of the elastic sheet is in contact with the inner wall of the receiving groove.

[0012] Preferably, the outer surface of the arc-shaped piece is provided with anti-slip teeth.

[0013] Preferably, the end of the column away from the embedded block has a chamfer.

[0014] Preferably, the height of the embedded block is 0.5 to 0.8 times the depth of the receiving groove.

[0015] Compared with existing technologies, this solution has the following advantages:

[0016] The connector in this case features an embedded block with a column on it. After holes are drilled in the side wall of the cabinet, the expansion column of the base is inserted into the holes, and then the column of the embedded block is inserted into the through hole of the expansion column. This causes the arc-shaped piece of the expansion column to open outward, thus fixing the arc-shaped piece to the hole in the cabinet and increasing the clamping force between the arc-shaped piece and the hole in the cabinet, thereby improving the connection stability between the connector and the side wall of the cabinet. Moreover, if the connector becomes loose, the embedded block can simply be hammered in further to increase the opening angle of the arc-shaped piece, thus maintaining the clamping force between the arc-shaped piece and the hole in the cabinet and ensuring the connection stability between the connector and the side wall of the cabinet.

[0017] Secondly, the embedded block is inserted into the expansion column through the column body, and the embedded block is located in the receiving groove, which can enhance the structural strength of the connection part of the base. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application implemented as described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Example 1

[0025] refer to Figure 1-4 A furniture connector includes a base 1 and an insert block 2. The base 1 has a connecting portion 3 on the side facing the insert block 2, which connects to a groove of an external support plate. The connecting portion 3 has a receiving groove 4. The base 1 has an expansion column 5 formed by at least two arc-shaped pieces on the side away from the insert block 2. The expansion column 5 has a through hole 6 that penetrates the base 1 and the expansion column 5. The axial direction of the through hole 6 extends along the axial direction of the expansion column 5, and the through hole 6 gradually decreases in size in the direction away from the insert block 2. The insert block 2 is located in the receiving groove 4. The side of the insert block 2 facing the base 1 has a column 7, which is at least partially inserted into the through hole 6.

[0026] In this embodiment, the connector is mainly used in wardrobes, storage cabinets, and other cabinets. Holes matching the expansion column 5 are made on the side wall of the cabinet, and grooves matching the shape of the connecting part 3 are made on the tray. The tray can then be connected to the cabinet body using this connector. There are three arc-shaped pieces.

[0027] The specific usage process of this connector is as follows: Insert the expansion column 5 of the base 1 into the hole in the side wall of the cabinet, and make the bottom of the base 1 fit against the side wall of the cabinet. Then insert the column 7 of the embedded block 2 into the through hole 6 of the expansion column 5. As the column 7 is continuously inserted, the arc-shaped piece will gradually open and press against the hole in the side wall of the cabinet, thereby fixing the connector to the side wall of the cabinet. Then, align the groove of the tray with the connecting part 3, put the groove into the connecting part 3, and push the tray into the cabinet. The connecting part 3 supports the tray, thereby completing the installation of the cabinet.

[0028] It should be noted that during the initial installation of the connector, the size of the hole on the side wall of the cabinet needs to be controlled so that only half of the column 7 needs to be inserted into the through hole 6 of the expansion column 5 to press the arc-shaped piece against the hole on the side wall of the cabinet. This allows for the subsequent insertion of more columns 7 to maintain the arc-shaped piece pressing against the hole on the side wall of the cabinet. At the same time, the embedded block 2 needs to be ensured to be in the receiving groove 4 to prevent the tray from being unable to be pushed into the cabinet.

[0029] Preferably, the connecting part 3 consists of two elastic blocks arranged opposite to each other and spaced apart along the width direction of the base 1; the receiving groove 4 is the gap between the two elastic blocks.

[0030] In this embodiment, by setting two elastic blocks arranged opposite to each other, after the elastic blocks are inserted into the groove of the tray, the elastic blocks press against the groove of the tray through elastic deformation, so that after the tray is installed, the connecting part 3 fits more closely to the inner wall of the groove, reducing the risk of the tray shaking.

[0031] It should be noted that both the base 1 and the connecting part 3 are located within the groove of the tray during installation, in order to enhance the support strength of the connector and prevent the connector from protruding from the cabinet and affecting the aesthetics.

[0032] Preferably, both elastic blocks are provided with a first through groove 8, the length direction of the first through groove 8 extending along the arrangement direction of the two elastic blocks; the embedded block 2 is provided with a second through groove 9, the length direction of the second through groove 9 extending along the arrangement direction of the two elastic blocks, the second through groove 9 and the first through groove 8 being directly opposite each other along the arrangement direction of the two elastic blocks, the second through groove 9 and the first through groove 8 cooperating to allow the external tool to pass through the first through groove 8 and the second through groove 9 to pry open the embedded block 2.

[0033] In this embodiment, by setting the first through groove 8 and the second through groove 9, when it is necessary to remove the connector from the side wall of the cabinet, it is only necessary to use a screwdriver or pry bar to insert from the first through groove 8 of one of the elastic blocks into the second through groove 9, thereby removing the embedded block 2 from the base 1. At this time, the arc-shaped piece will return to its initial state, and then the connector can be easily removed from the side wall of the cabinet.

[0034] Preferably, the outer wall of the end of the elastic block away from the base 1 is provided with a positioning boss 10, and the side of the positioning boss 10 away from the base 1 is provided with a guide slope 11.

[0035] In this embodiment, the groove of the tray is provided with a part that matches the positioning boss 10. By providing the positioning boss 10, the elastic block can fit better with the groove of the tray, thus preventing the tray from shifting left or right after installation.

[0036] Secondly, the connectors can also be used on solid wood grilles used for decorative background walls. Solid wood grilles consist of a panel and grille strips. Corresponding holes are pre-drilled in the panel, and the connectors are then installed on the panel using the same method as those used for cabinet installation. Corresponding grooves are pre-drilled in the grille strips; these grooves are then aligned with the connector 3, and the grille strips are pressed firmly to connect them to the connector, thus fixing the grille strips to the panel. The guide slope 11 facilitates the installation of the grille strips onto the connectors.

[0037] Preferably, the embedded block 2 is provided with elastic sheets 12 on both sides along its length direction. The elastic sheets 12 are arranged obliquely along the arrangement direction of the base 1 and the embedded block 2, and the free end of the elastic sheet 12 is in contact with the inner wall of the receiving groove 4.

[0038] In this embodiment, the elastic sheet 12 is obliquely upwardly disposed on the embedded block 2. By disposing of the elastic sheet 12 and the inner wall of the receiving groove 4 on both sides of the embedded block 2, the support strength of the connecting part 3 on the tray can be increased. Moreover, when the elastic sheet 12 is placed in the receiving groove 4, it will undergo elastic deformation, causing the elastic sheet 12 to press against the inner wall of the receiving groove 4, thereby making the connecting part 3 and the tray fit more closely.

[0039] Preferably, the outer surface of the arc-shaped piece is provided with anti-slip teeth 13. By providing anti-slip teeth 13, the friction between the expansion column 5 and the hole in the side wall of the cabinet is increased, reducing the probability of the connector becoming loose.

[0040] Preferably, the end of the column 7 away from the embedding block 2 is provided with a chamfer 14. By providing the chamfer 14, it is easier for the column 7 to be inserted into the through hole 6.

[0041] Preferably, the height of the embedded block 2 is 0.5 to 0.8 times the depth of the receiving groove 4.

[0042] In this embodiment, the height of the embedded block 2 is 0.5 times the depth of the receiving groove 4. Since the column 7 is half inserted into the through hole 6 when it is first inserted, this setting can ensure that the embedded block 2 can be in the receiving groove 4.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
