Description

Technical Field

[0001] The utility model relates to a connecting component of a furniture plate body, in particular to a connecting piece for a hollow plate. 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, and the two panels are connected and fixed together. However, with the emergence of hollow panels, the structure of traditional furniture panel connectors cannot meet the needs of both panel strength and connection firmness.

[0003] Chinese patent document CN218844769U discloses a furniture panel connector for honeycomb panels, which is a combination structure of an eccentric wheel located in a shell, a connecting rod, and a fixing component located on the panel B, to achieve the fixation and connection of panel A and panel B. Although this structure meets the requirements of both panel strength and connection firmness to a certain extent, the connector still has technical defects in actual use. In this connector structure, a combination structure of a fixing plate and a fixing nail is adopted. However, the honeycomb panel has the characteristic of being hollow, and the contact area between the fixing nail and the panel is small. Moreover, as the panel is moved and loaded, the connection between the panel and the fixing nail will be deformed outward. In addition to causing deformation of the panel connection, the above deformation may also cause the connector to fall off in severe cases. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a connecting piece for hollow plates which is stable, reliable and firm.

[0005] The utility model provides a connecting piece for a hollow plate, which is mainly composed of an eccentric wheel, a connecting rod, a connecting sleeve and a connecting head. The connecting sleeve is installed in a plate body A by plugging, the connecting rod and the eccentric wheel are both arranged in the connecting sleeve, one end of the connecting head is arranged in a plate body B, and the other end is located at the end of the connecting rod exposed in the connecting sleeve, and is connected to the connecting rod by a threaded connection, and the connecting head is opened outward after connection and buckled in the plate body B.

[0006] By improving the above structure, a first accommodating chamber and a second accommodating chamber are provided in the connecting sleeve. The axes of the first accommodating chamber and the second accommodating chamber intersect vertically and are used to accommodate the eccentric wheel and the connecting rod respectively, so as to realize the buckling connection between the eccentric wheel and the connecting rod in the connecting sleeve.

[0007] By further improving the above structure, the connector is further provided with a positioning platform, which is located at one side where the connector is connected to the connecting sleeve and is matched and connected with the inner wall of the second accommodating cavity to realize radial positioning of the connector on the connecting sleeve.

[0008] By further improving the above structure, the connecting rod is further provided with a positioning piece, which can be pressed against the positioning platform when the connecting head is inserted into the connecting sleeve to achieve axial positioning between the connecting rod and the connecting head.

[0009] By improving the above structure, the connector further has an inclined portion, which is integrally formed with the connector, extends along the axial direction of the connector, and corresponds to the position of the connecting rod.

[0010] Compared with the prior art, the hollow plate connector of the utility model utilizes the connection between the eccentric wheel and the connecting rod, so that the connecting sleeve and the connecting head respectively drive the plate body A and the plate body B to form a fixed connection structure. Its beneficial effects are:

[0011] First, the engagement of the eccentric wheel and the connecting rod can make the plate A and plate B gradually approach and finally connect together under the action of the opposite pulling force. The connector can be connected to the plate B with the least number of openings on the plate B, and the outward expansion of the connector can realize the filling-type connection between the openings and the interior of the plate B. This connection method can prevent the loosening or detachment of the connector due to the deformation of the plate body under force, and ensure the stability and reliability of the connection between the plate body A and the plate body B.

[0012] Secondly, a positioning platform is provided on the connector, and the positioning platform is matched and connected with the inner wall of the second accommodating cavity. The positioning platform can produce a radial positioning effect between the connector and the connecting sleeve, so as to prevent the connector from shaking on the connecting sleeve due to force after the plate body A and the plate body B are connected, thereby enhancing the reliability of the connection between the plate body A and the plate body B.

DETAILED DESCRIPTION

[0020] 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 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.

[0021] according to Figures 1 to 6 As shown, the connector for hollow plate materials of the utility model is mainly composed of a connecting sleeve 1, a connecting rod 2, an eccentric wheel 3 and a connecting head 4. The connecting sleeve 1 is inserted into the plate body A01, and the connecting head 4 is inserted into the plate body B02. Both the plate body A01 and the plate body B02 are hollow plates. The connecting rod 2 and the eccentric wheel 3 are arranged in the connecting sleeve 1, and the two are buckled and connected together. The rotation of the eccentric wheel 3 generates a centripetal pulling force on the connecting rod 2, so that the plate body A01 and the plate body B02 are close to each other and finally connected. The other end of the connecting rod 2 extends out of the connecting sleeve 1 and is connected to the connecting head 4. In the process of connecting the connecting rod 2 and the connecting head 4, the connecting head 4 will open outward after being subjected to force, and be buckled on the inner side of the plate body B02.

[0022] In one embodiment of the utility model, a first accommodating chamber 11 and a second accommodating chamber 12 are provided in the connecting sleeve 1. The first accommodating chamber 11 and the second accommodating chamber 12 can be integrally processed in the connecting sleeve 1, arranged in a manner that the axes intersect vertically, and are used to accommodate the eccentric wheel 3 and the connecting rod 2, respectively. The eccentric wheel 3 can rotate in the first accommodating chamber 11, and the connecting rod 2 can move along its axial direction in the second accommodating chamber 12. The provision of the first accommodating chamber 11 and the second accommodating chamber 12 can ensure the stability of the fastening between the eccentric wheel 3 and the connecting rod 2, and the connecting rod 2 is not only subjected to axial tension, but also radially affected by the lateral positioning stress of the eccentric wheel 3. Therefore, after the connection, the connecting rod 2 will not gradually deviate in the direction away from the eccentric wheel 3 due to load-bearing, force, etc., thereby ensuring the reliability of the fastening between the eccentric wheel 3 and the connecting rod 2. In fact, an anti-skid groove 31 can be provided on the outer side of the eccentric wheel 3, and the anti-skid groove 31 can increase the friction between the outer surface of the eccentric wheel 3 and the inner wall of the first accommodating chamber 11, so as to prevent the eccentric wheel 3 from rotating due to the force applied to the plate body. In addition, an anti-skid boss 32 can be provided on the side of the eccentric wheel 3, and the anti-skid boss 32 is processed in an integrally formed manner with the eccentric wheel 3 and protrudes from the side of the eccentric wheel 3, so as to further prevent the eccentric wheel 3 from rotating due to the force applied, and further enhance the stability of the connection between the plate body A01 and the plate body B02.

[0023] In another embodiment of the utility model, the connector 4 is further provided with a positioning platform 41. The positioning platform 41 and the connector 4 are processed in an integrally formed manner, and the side of the positioning platform 41 can be matched and connected with the inner wall of the second accommodating chamber 12. When the eccentric wheel 3 rotates and pulls the plate body B02 through the connecting rod 2, the rotation of the eccentric wheel 3 causes the connecting rod 2 to be subjected to radial positioning stress in addition to the axial tension. The positioning stress will form a radial moment acting on the connector 4 under the action of the force arm formed in the length direction of the connecting rod 2, causing the connector 4 to tilt radially when the plate body is subjected to force. The connection between the positioning platform 41 and the second accommodating chamber 12 can form radial positioning at both ends of the connecting rod 2, thereby avoiding the influence of the positioning stress on the position stability of the connector 4.

[0024] In another embodiment of the utility model, the connecting rod 2 is further provided with a positioning piece 21. The positioning piece 21 and the connecting rod 2 can also be processed in an integrally formed manner, and can be pressed against the positioning platform 41. The connection between the plate body A01 and the plate body B02 is achieved by the pulling effect of the connecting rod 2 caused by the rotation of the eccentric wheel 3. When the eccentric wheel 3 rotates excessively, the connection between the plate body A01 and the plate body B02 will become too tight, and at this time, a reverse stress opposite to the installation direction will appear between the connecting sleeve 1 and the connecting head 4. The existence of this reverse stress will cause the plate body A01 and the plate body B02 to have a tendency to separate when the plate body is subjected to force, thereby reducing the stability of the connection between the two plate bodies. The connection between the positioning piece 21 and the positioning platform 41 can form an axial movement positioning for the positioning platform 41 to avoid excessive rotation of the eccentric wheel 3 during installation.

[0025] In another embodiment of the utility model, the connector 4 also has an inclined portion 42. The inclined portion 42 can be directly processed on the connector 4, and extends along the axial direction of the connector 4, and gradually closes the connector 4 in the direction away from the eccentric wheel 3. At the same time, the position of the inclined portion 42 corresponds to that of the connecting rod 2. When the connecting rod 2 is threadedly connected to the connector 4, its end gradually enters the connector 4 along the inclined portion 42 and forms a threaded connection with the inclined portion 42. As the connecting rod 2 continues to enter, it is tilted and supported by force, and gradually buckled inside the plate body B02 to improve the reliability of the connection between it and the plate body B02. The connector 4 also has a positioning flange 43, an undercut tooth 44 and a reinforcing rib 45, and the positioning flange 43, the undercut tooth 44 and the reinforcing rib 45 are all integrally formed with the connector 4. The positioning flange 43 is located between the connector 4 and the positioning platform 41, which can control the depth of the connector 4 entering the plate body B02, so that the connector 4 is axially positioned in the plate body B02. The undercut teeth 44 are located at the side of the connector 4, which can play an undercut role after being connected to the plate body B02. The reinforcing ribs 45 are located at the side of the undercut teeth 44, which can strengthen the overall strength of the connector 4 when it is stretched out, and prevent the connector 4 from being deformed and falling out of the plate body B02 when the plate body B02 is loaded or stressed.

[0026] When installing the connector of the utility model, firstly, mounting holes are processed on the plate body A01 and the plate body B02 respectively, and then the connecting sleeve 1 and the connecting head 4 are respectively installed in the plate body A01 and the plate body B02 by applying pressure. Then the connecting rod 2 is inserted into the connecting head 4 and rotated, and the connecting rod 2 taps the inclined portion 42 while rotating, and stops when the positioning piece 21 is connected to the positioning platform 41. Then, the eccentric wheel 3 is installed in the first accommodating chamber 11, and then the connecting rod 2 is inserted into the second accommodating chamber 12, and the eccentric wheel 3 and the head of the connecting rod 2 are interlocked. Finally, the eccentric wheel 3 is rotated to achieve the fixed connection between the plate body A01 and the plate body B02.

[0027] As for the connection principle and connection relationship between the connecting rod 2 and the eccentric wheel 3 in the present invention, reference can be made to the description in the Chinese patent document CN218844769U, which will not be repeated here. The above specific embodiments are only implementation methods with better technical effects of the present invention, and all structures that are the same or equivalent to the hollow plate connector of the present invention are within the protection scope of the present invention.
