Description

Technical Field

[0001] The utility model relates to a connecting component of a furniture plate, in particular to an axially positionable furniture plate connecting piece. Background Art

[0002] Panel connectors are commonly used components in furniture production and assembly. They are generally composed of three parts: an eccentric wheel, a connecting rod, and a connecting head. The working principle of traditional panel connectors is that the eccentric wheel rotates to drive the connecting rod and the connecting head to move in the direction where the two panels meet, thereby connecting and fixing the two panels together.

[0003] Chinese patent document CN217842248U discloses a connector and a furniture plate connecting structure, wherein a first plate and a second plate are fixed to each other by sliding and plugging a positioning member in a body. During installation, a tool is used to insert the notch of the installation section of the body, and the end of the connecting section of the body is inserted along the thickness direction of the first plate. An external force is applied to rotate the connector so that it is completely inserted into the first plate, and the thread of the outer wall of the body is firmly connected to the first plate, and the bite portion is also firmly connected to the first plate. However, the connector still has technical defects in actual use. First, since the body is connected to the inner wall of the first plate through the thread of the outer wall, a positioning member cannot be set in the axial direction of the body. The reason is that the outer circumference of the axial positioning member of the body is larger than the body itself. When the positioning member is located on the side of the body, it will continuously scrape the inner cavity of the plate during the rotation of the body; when the positioning member is located on the end face between the body and the plate, it will continuously scrape the surface of the plate when the body is close to the plate, which seriously affects the normal connection between the body and the plate. Secondly, since the main body cannot be provided with a positioning component, multiple main bodies installed on the same plate will have inconsistent installation depths. This will not only cause bending stress to be generated after the positioning component and the main body are plugged in because the buckling positions are not on the same horizontal plane, but in serious cases, part of the positioning component will be separated from the main body, resulting in the inability to connect the two plates smoothly. Summary of the invention

[0004] The utility model aims to overcome the shortcomings of the prior art and provide a furniture plate connecting piece which has reliable connection and can be positioned in the axial direction.

[0005] The utility model provides an axially positionable furniture panel connector, which is mainly composed of a connecting rod and a connecting sleeve. The connecting rod is fixed on the panel B, and the connecting sleeve is fixed in the panel A. The connecting rod and the connecting sleeve are movably connected, and the panel A and the panel B are connected together during the mutual movement. The connecting sleeve has an expansion portion at one end located in the panel A, and a buckle joint is provided on the connecting rod. When the connecting rod slides in the connecting sleeve, the buckle joint can be buckled with the expansion portion. The side wall of the connecting sleeve also has an outward expansion portion, which can be snapped on the side of the panel A to prevent the connecting sleeve from retreating from the panel A. The end of the connecting sleeve also has a positioning piece, which can be pressed against the panel A to achieve axial positioning of the connecting sleeve.

[0006] By optimizing the above structure, the expansion part is composed of at least two expansion pieces, which are evenly distributed on the end of the connecting sleeve, and the expansion pieces are inclined to the inner side of the connecting sleeve in a frustum shape. The end of the expansion part is also provided with an undercut block, which can be expanded outward when the expansion piece moves radially along the connecting sleeve and is buckled on the inner wall of the plate body A.

[0007] By further optimizing the above structure, the diameter of the buckle joint is larger than the minimum diameter of the cone formed by the expansion piece and smaller than the inner diameter of the connecting sleeve.

[0008] By further optimizing the above structure, the buckle joint has a cone-shaped structure, the bottom diameter of which is larger than the minimum diameter of the cone formed by the expansion sheet and smaller than the inner diameter of the connecting sleeve, so that the expansion sheet can be spread open and inverted on the expansion sheet when the buckle joint passes through the cone.

[0009] According to further optimization of the above structure, the outwardly extending portion is fixed to the side of the connecting sleeve and is inclined along the direction in which the connecting sleeve is inserted into the plate body A, so that the connecting sleeve can be smoothly inserted into the plate body A.

[0010] According to further optimization of the above structure, a fixing part is further provided between the connecting rod and the plate body B. The fixing part includes a connecting head arranged in the plate body B and a rod body threadedly connected to the connecting head.

[0011] Compared with the prior art, the axially positionable furniture plate connector of the utility model has a connection sleeve fixed to the plate body A through an outwardly extending portion, and a positioning piece is arranged at the end of the connection sleeve. The beneficial effects are:

[0012] First, an undercut structure is formed between the outer part and the plate body A. After the connecting sleeve is installed in the plate body A, the outer part is undercut on the inner wall of the plate body A to prevent the connecting sleeve from being forced out of the plate body A, thereby ensuring the stability of the connection between the plate body A and the plate body B. At the same time, the connecting sleeve can be installed into the plate body A by simply applying pressure, without the assistance of additional tools, making the installation of the connector more convenient.

[0013] Secondly, the positioning piece can be pressed against the plate body A when the connecting sleeve is installed. This structure realizes the axial positioning of the connecting sleeve, ensures that the depths of multiple connecting sleeves installed on the plate body A are consistent, and avoids the situation where the plate body is subjected to flexural stress.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The applicant hereby emphasizes that the following embodiments are one or several examples that can realize the new technical solutions of the utility model, obtain corresponding technical effects, and solve corresponding technical problems, and do not mean that the protection scope of the technical solution only includes the following embodiments.

[0020] according to Figures 1 to 4As shown, the axially positionable furniture panel connector of the utility model is mainly composed of a connecting sleeve 2 and a connecting rod 1. The connecting rod 1 is fixed on the panel B02, and the connecting sleeve 2 is fixed in the panel A01. The connecting sleeve 2 adopts a hollow structure, and the connecting rod 1 is inserted in the connecting sleeve 2, and the connection between the panel A01 and the panel B02 is achieved by the mutual movement of the two in the axial direction. The connecting sleeve 2 also has an expansion part, which is located at one end of the connecting sleeve 2 on the inner side of the panel A01. The expansion part can be processed in an integral molding manner with the connecting sleeve 2, so that the expansion part and the connecting sleeve 2 form an integral connection effect. The connecting rod 1 has a buckle joint 11, and the buckle joint 11 can also be integrally processed on the connecting rod 1, so that when the connecting rod 1 moves in the connecting sleeve 2, the buckle joint 11 and the expansion part can be ensured to move relative to each other synchronously. The connecting sleeve 2 of the utility model also has an outward expansion portion 23, which is located on the side wall of the connecting sleeve 2. The outward expansion portion 23 is processed in an integral manner with the connecting sleeve 2, and can be clamped on the inner side of the plate body A01 after the connecting sleeve 2 enters the inside of the plate body A01 to prevent the connecting sleeve 2 from moving in the opposite direction after being connected to the plate body A01. In addition, the connecting sleeve 2 also has a positioning member 24. The positioning member 24 is located at one end of the connecting sleeve 2 away from the plate body A01, and is processed in an integral manner with the connecting sleeve 2, and can be pressed against the plate body A01 when the connecting sleeve 2 is inserted into the plate body A01 to achieve the axial positioning of the connecting sleeve 2.

[0021] In one of the embodiments of the utility model, the expansion portion is composed of at least two expansion sheets 21, and are evenly distributed on the outer periphery of the end of the connecting sleeve 2, so that the inner side of the expansion portion can be evenly opened when force is applied. The expansion sheet 21 is inclined toward the inner side of the connecting sleeve 2 to form an inwardly retracted cone-shaped structure, and the diameter of the cone-shaped structure gradually decreases in the direction away from the connecting sleeve 2. The expansion sheet 21 also has an undercut portion 22 at one end away from the connecting sleeve 2. The undercut portion 22 and the expansion sheet 21 can also be processed in an integral molding manner, and can be buckled on the inner side of the plate body A01 when the expansion sheet 21 is extended outward. In this embodiment, the minimum diameter of the cone-shaped structure is smaller than the diameter of the connecting sleeve 2, and after the structure wraps the connecting rod 1, it can ensure that the undercut portion 22 is pressed against the inner side of the plate body A01.

[0022] In another embodiment of the utility model, according to the actual connection requirements of the connecting rod 1 and the connecting sleeve 2, the user can also set the buckle joint 11 to be a frustum, and the inclination direction of the frustum is opposite to the frustum structure formed by the expansion sheet 21. The diameter of the buckle joint 11 is larger than the minimum diameter of the frustum formed by the expansion sheet 21, and smaller than the inner diameter of the connecting sleeve 2. This is to achieve that the buckle joint 11 is stretched open when passing through the expansion sheet 21, and after passing through the expansion sheet 21, the expansion sheet 21 is wrapped around the connecting rod 1 under the action of the elastic restoring force.

[0023] In another embodiment of the utility model, the outer expansion portion 23 is a sheet-like structure, and gradually tilts outward along the plugging direction of the connecting sleeve 2 in the plate body A01. The sheet-like structure enables the outer expansion portion 23 to form an obtuse angle with the insertion direction of the connecting sleeve 2, ensuring the smoothness of the connecting sleeve 2 entering the plate body A01. The outer expansion portion 23 forms an acute angle with the retreat direction of the connecting sleeve 2, ensuring that once the connecting sleeve 2 retreats, the outer expansion portion 23 can be clamped on the inner side of the plate body A01 to prevent the connecting sleeve 2 from falling out.

[0024] In another embodiment of the utility model, there is a fixing part between the connecting rod 1 and the plate body B02. The fixing part is composed of a connector 12 and a rod body 13, wherein the connector 12 is located inside the plate body B02 and is a hollow structure. The rod body 13 is coaxially integrally formed with the connecting rod 1 and is threadedly connected to the connector 12. When the rod body 13 rotates continuously, it penetrates into the connector 12 and opens the connector 12 to be buckled on the inner side of the plate body B02.

[0025] When installing the connector of the utility model, firstly, two coaxial blind holes are processed in the plate body A01 and the plate body B02 respectively, and then pressure is applied at the end of the connecting sleeve 2 to make it enter the blind hole of the plate body A01, and the positioning member 24 is pressed against the plate body A01. Then, the connecting head 12 is inserted into the plate body B02, and the connecting head 12 is expanded outward by rotating the rod body 13 to achieve the fixation of the connecting rod 1 and the plate body B02. Finally, the end of the connecting rod 1 exposed outside the plate body B02 is inserted into the connecting sleeve 2. When the connecting head 12 passes through the expansion sheet 21 and generates an undercut tension, the fixed connection between the plate body A01 and the plate body B02 can be achieved.

[0026] The above-mentioned specific embodiments are only implementation methods with better technical effects of the present utility model. Any structure that is the same or equivalent to the axially positionable furniture panel connector of the present utility model is within the protection scope of the present utility model.
