Description

TECHNICAL FIELD

[0001] The utility model relates to the connection field of furniture board, specifically a connecting piece for honeycomb board. BACKGROUND

[0002] The board connecting piece is a commonly used furniture assembling component, which rotates through the eccentric wheel, drives the connecting rod and the connecting head to move the two boards towards each other and connect them together. At present, honeycomb boards for furniture have appeared in the market, which are favored by manufacturers due to their light weight. However, due to the hollow feature of the honeycomb board, the contact area between the inside of the board and the board connecting piece is small, which cannot meet the requirements of both the strength of the connected board and the connection strength.

[0003] Chinese patent document CN218844769U discloses a furniture board connecting piece for honeycomb board, which realizes the fixation of two boards through the mutual connection of eccentric wheel, connecting rod and fixing component. In this connecting piece, an auxiliary fixation structure of fixing sheet and fixing nail is adopted. However, the inherent hollow feature of the honeycomb board causes the contact area between the fixing nail and the connecting rod and the board to be always small when they are connected, and the threads at the contact position of the board and the fixing nail and the connecting rod are subjected to strong shearing action due to stress, which causes deformation of the connected position of the board or the falling off of the connecting piece. SUMMARY

[0004] The utility model aims at overcoming the deficiencies of the prior art and providing a connecting piece for honeycomb board with reliable connection and good firmness.

[0005] The utility model provides a connecting piece for honeycomb board, which comprises a connecting sleeve, a connecting rod, an eccentric wheel and a connecting head. The connecting sleeve and the connecting head are fixed in board A and board B respectively, and the connecting rod and the eccentric wheel are arranged in the connecting sleeve. The connecting head is located at the outer side of the connecting sleeve and is fixed together with the connecting rod. The side surface of the connecting head is a plane and is in interference fit with board B, and the inner cavity is in threaded connection with the connecting rod.

[0006] Through the improvement of the above structure, the connecting sleeve has a first accommodating cavity and a second accommodating cavity. The eccentric wheel and the connecting rod are arranged in the first accommodating cavity and the second accommodating cavity respectively, and are movably connected together after buckling.

[0007] Through the improvement of the above structure, the connecting head further has a positioning table, which is connected together with the outer side of board B.

[0008] Through the improvement of the above structure, the connecting rod further has a positioning sheet, which is connected together with the outer side of the connecting head.

[0009] Through the further improvement of the above structure, the connecting sleeve further has an anti-skid rib, which is located on the outer side surface of the connecting sleeve.

[0010] The connecting piece for the cellular board has the advantages that, compared with the prior art,

[0011] 1. The connecting head and the plate body B are fixed together in an interference fit mode, which can first avoid the existing threaded connection mode from generating too large shearing stress on the plate body, so that the plate body is not easily deformed after being subjected to external force. Secondly, the interference fit mode can realize seamless connection between the connecting head and the plate body B, the external force borne by the plate body B after being transmitted by the connecting head becomes more stable, in addition to avoiding the two plate bodies from being loose after being assembled, the external force can also be evenly dispersed in the plate body B, avoiding the accumulation of the external force at the contact part of the plate body B and the connecting head, and improving the stability and reliability of the connection between the plate body A and the plate body B.

[0012] 2. The connecting head is provided with a positioning table connected to the outer side of the plate body B, and the connecting rod is provided with a positioning piece connected to the outer side of the connecting head. In addition to forming a positioning structure in the axial direction of the connecting head and the connecting rod, the positioning table and the positioning piece can also effectively transmit the external force between the plate body A and the plate body B, and disperse the external force in the plate body A and the plate body B, so that one of the plate bodies is not deformed due to too large force, and the firmness of the connection between the plate body A and the plate body B is improved.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. The following embodiments are one or several examples capable of realizing the technical solutions of the utility model, obtaining corresponding technical effects and solving corresponding technical problems, and do not mean that the protection scope of the technical solutions only includes the following embodiments.

[0021] According to Figures 1 to 6 As shown in the utility model discloses a connecting piece for honeycomb plate mainly comprises connecting sleeve 1, connecting rod 2, eccentric wheel 3 and connecting head 4. Among them, connecting sleeve 1 is inserted in plate body A01, and is fixed together with plate body A01. Connecting head 4 is inserted in plate body B02, and is fixed together with plate body B02, and plate body A01 and plate body B02 are all hollow honeycomb plate. Connecting rod 2 is fixed together with connecting head 4, so that connecting head 4 and plate body B02 can be moved simultaneously when connecting rod 2 moves. Connecting head 4 and plate body B02 are connected in an interference fit, and the side surface of connecting head 4 is connected with the inner wall of plate body B02, which can be a plane or a slightly convex arc surface, to avoid the side surface of connecting head 4 from forming a shearing action on the inner wall of plate body B02. In fact, in the existing plate connecting piece structure, in order to increase the friction between the connecting head 4 and the inner wall of the plate, or to enable the connecting head 4 to be inverted on the inner wall of the plate, the side of the connecting head 4 is generally provided with a continuous tooth structure, which exactly forms a shearing action between the connecting head 4 and the inner wall of the hollow plate. Connecting rod 2 and the inner cavity of connecting head 4 are fixed together by threaded connection, so that connecting head 4 and plate body B02 can be moved simultaneously when connecting rod 2 moves. In the utility model, the outer side of eccentric wheel 3 can also be provided with a cover 5, and a plug hole 31 can be formed in the end face of eccentric wheel 3, and a plug 51 matched with the plug hole 31 can be arranged on the cover 5. After the plug 51 is installed in the plug hole 31, the cover 5 can cover the eccentric wheel 3 to avoid its exposure.

[0022] In one embodiment of the utility model, the connecting sleeve 1 has a first accommodating cavity 11 and a second accommodating cavity 12. The first accommodating cavity 11 and the second accommodating cavity 12 can be directly machined on the connecting sleeve 1, and the axes of the two are perpendicular to each other. The eccentric wheel 3 and the connecting rod 2 are arranged in the first accommodating cavity 11 and the second accommodating cavity 12 respectively, and the eccentric wheel 3 can rotate around the shaft in the first accommodating cavity 11. The eccentric wheel 3 and the connecting rod 2 are connected movably by buckling, so that the connecting rod 2 receives a pulling force away from the plate body B02 when the eccentric wheel 3 rotates, thereby realizing the mutual approach of the plate body A01 and the plate body B02. The connection principle and connection relationship of the connecting rod 2 and the eccentric wheel 3 can be referred to the description in Chinese patent document CN218844769U, which will not be repeated here.

[0023] In another embodiment of the utility model, the connecting head 4 is further provided with a positioning table 41. The positioning table 41 is located at the outer edge of the end surface of the connecting head 4 close to the plate body A01, and is integrally formed with the connecting head 4. The positioning table 41 is connected to the outer side of the plate body B02 to limit the positioning table 41 along its axis.

[0024] In another embodiment of the utility model, the connecting rod 2 is further provided with a positioning sheet 21. The positioning sheet 21 is located at the outer edge of the side of the connecting rod 2 close to the connecting head 4, and is integrally formed with the connecting rod 2. The positioning sheet 21 can be pressed against the outer side of the connecting head 4, specifically the end surface of the connecting head 4, during the connecting process of the connecting rod 2 and the connecting head 4, to control the installation depth between the connecting rod 2 and the connecting head 4.

[0025] In another embodiment of the utility model, the connecting sleeve 1 is further provided with an anti-skid rib 13. The anti-skid rib 13 is located on the outer side of the connecting sleeve 1, and can be integrally formed with the connecting sleeve 1 to increase the friction between the connecting sleeve 1 and the inner wall of the plate body A01.

[0026] When the connecting piece of the utility model is installed, first, mounting holes are processed on the plate body A01 and the plate body B02 respectively, 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, and the connecting head 4 can stop applying pressure when the positioning table 41 contacts the outer surface of the plate body B02. Then the connecting rod 2 is inserted and connected on the connecting head 4 and rotated, the connecting rod 2 is fixed while rotating and contacting the connecting head 4, and stops when the positioning sheet 21 contacts the end surface of the connecting head 4. Then the eccentric wheel 3 is inserted and connected in the first accommodating cavity 11, and the connecting rod 2 is inserted into the second accommodating cavity 12 and the head of the eccentric wheel 3 and the connecting rod 2 are buckled with each other. Finally, the eccentric wheel 3 is rotated, and the plate body A01 and the plate body B02 are fixedly connected.

[0027] The above specific embodiments are only the implementation modes of the utility model with better technical effects, and any structure identical or equivalent to the connecting piece for honeycomb plates within the protection scope of the utility model.
