Description

Technical Field

[0001] The utility model relates to a connection and installation component for furniture plates, in particular to a tensioning type furniture layer plate support. Background Art

[0002] A shelf support is a type of sheet material connector, which is mainly used to install two panels with installation angles. Chinese patent document CN216788904U discloses a multi-point positioning snap-fit ​​furniture shelf support, which uses a sliding connection between a slider and a slide groove to achieve the fixation between the two panels. However, the shelf support of this structure still has technical defects.

[0003] First, in the above-mentioned layer support structure, the connector forms a sliding connection with the connecting seat through the slide groove provided therein and the slider provided on the connecting seat, so the relative position of the connector and the connecting seat in the axial direction is fixed. However, since there is a certain span between the plate bodies when installing the layer support, the processing error of the layer support itself and the distance between the two layer supports will form an axial tensile torque. This tensile torque will cause the connector and the connecting seat to be pulled continuously, which will not only cause gaps between the plates, but also cause the connector and the connecting seat to be separated or broken in serious cases.

[0004] Secondly, the plate itself also has processing errors and dimensional errors. The relatively fixed connector and connector seat cannot adjust the installation position, which will hinder the normal installation of the plate. Summary of the invention

[0005] The utility model aims to overcome the deficiencies of the prior art and provide a tensioning furniture shelf support which is easy to install and has good reliability.

[0006] The utility model provides a tensioning furniture layer support, which mainly includes a connecting rod and a connecting seat. The connecting rod is fixedly arranged on the plate body A, and the connecting seat is fixed on the plate body B. The positions of the connecting rod and the connecting seat correspond to each other, so that the two can realize the connection between the plate body A and the plate body B while being connected. An accommodating cavity is provided inside the connecting seat, and the connecting rod is also provided with a buckle joint, which can be extended into the accommodating cavity. An eccentric wheel is also installed in the accommodating cavity, and the eccentric wheel can rotate around the axis in the accommodating cavity and buckle with the buckle joint.

[0007] By optimizing the above structure, the accommodating cavity is further provided with a positioning platform, which can be integrally formed on the connecting seat. The eccentric wheel is further provided with a positioning block, which can also be integrally formed with the eccentric wheel and can be pressed against the positioning platform when the eccentric wheel is installed in the accommodating cavity to achieve axial positioning between the eccentric wheel and the connecting seat.

[0008] By optimizing the above structure, an undercut tooth is further provided on the outer side of the connection seat. The undercut tooth is processed in an integrally formed manner with the connection seat and is buckled on the inner side of the plate body B when the connection seat is connected to the plate body B.

[0009] By further improving the above structure, the connecting seat is also provided with a cover. The cover can shield the eccentric wheel in the accommodating cavity to prevent the eccentric wheel from being exposed. A positioning hole is also provided on the connecting seat, and a positioning column is also provided on the cover. The positioning hole and the positioning column are matched and connected to realize the fixed connection between the cover and the connecting seat.

[0010] The beneficial effects of the tensioning furniture shelf support of the utility model are:

[0011] 1. The layer support of the utility model adopts a buckling structure of a buckle joint and an eccentric wheel. First, due to the buckling effect between the eccentric wheel and the buckle joint, the buckle joint will drive the connecting rod to move axially when the eccentric wheel rotates, and the plate body A and the plate body B will gradually approach and fit tightly. This structure can effectively improve the reliability of the connection between the plate body A and the plate body B, and prevent the situation where the layer support cannot be installed normally due to the processing error and dimensional error of the plate body. Secondly, during the buckling process of the eccentric wheel and the buckle joint, the tightness of the connection between the plate body A and the plate body B can be adjusted according to the tightness of the rotation of the eccentric wheel, so as to avoid the tensile torque of the plate body after installation, thereby improving the stability of the layer support connection.

[0012] 2. In the layer support structure of the utility model, a positioning platform is also provided in the accommodating cavity, and a positioning block that can be pressed on the positioning platform is provided on the eccentric wheel. The cooperation between the positioning platform and the positioning block can realize the axial positioning of the eccentric wheel in the connecting seat, avoid axial deviation when the eccentric wheel and the connecting rod are assembled, and ensure the reliability of the buckling of the two.

DETAILED DESCRIPTION

[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 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 5 As shown, the tensioning furniture layer support of the utility model is mainly composed of a connecting rod 1, a connecting seat 2, a buckle joint 11 and an eccentric wheel 3. The connecting rod 1 is fixed on the plate body A01, and it can be fixed to the plate body A01 by threaded connection or snap connection. The threaded connection is adopted in the utility model. The connecting seat 2 is arranged on the plate body B02, and it can be directly embedded in the inside of the plate body B02 by plugging. The positions of the connecting rod 1 and the connecting seat 2 correspond to each other, so that the plate body A01 and the plate body B02 can be fixed to each other by the connection between the two. A receiving chamber 21 is provided in the connecting seat 2, which is used to accommodate the eccentric wheel 3. The receiving chamber 21 can be integrally processed inside the connecting seat 2 and communicated with the outside of the connecting seat 2. In the utility model, the receiving chamber 21 passes through the connecting seat 2 front and back along the axial direction of the eccentric wheel 3, so that the eccentric wheel 3 can be installed from the end away from the outside of the plate body B02 through the connecting seat 2. The connecting rod 1 has a snap joint 11, which is located at one end of the connecting rod 1 away from the plate body A01 and is processed in an integral manner with the connecting rod 1. The snap joint 11 can extend into the accommodating chamber 21 through the connecting seat 2. The eccentric wheel 3 is located in the accommodating chamber 21, which is arranged by plugging and can rotate around the axis of the eccentric wheel 3. The opening of the eccentric wheel 3 corresponds to the position of the snap joint 11, so that when the eccentric wheel 3 rotates, it can continuously pull the connecting rod 1 to make axial movement after being snapped and connected with the snap joint 11. Regarding the specific structure of the eccentric wheel 3, those skilled in the art can refer to the eccentric wheel 3 structure of Chinese patent documents CN203516320U and CN205559464U, which will not be repeated here.

[0021] In one embodiment of the utility model, a positioning platform 22 is provided in the accommodating cavity 21, and a positioning block 31 is provided on the eccentric wheel 3. The positioning block 31 and the positioning block 31 can be processed in an integrally formed manner in the connecting seat 2 and the outer side of the eccentric wheel 3, respectively, and the positions of the two are corresponding, so that after the eccentric wheel 3 is inserted into the accommodating cavity 21, the axial positioning of the eccentric wheel 3 is realized through the mutual pressing action of the positioning platform 22 and the positioning block 31, so as to avoid the misalignment of the eccentric wheel 3 and the buckle joint 11 during installation.

[0022] In another embodiment of the utility model, the outer side of the connection seat 2 is further provided with an undercut tooth 23. The undercut tooth 23 is used to be undercut on the inner side of the plate body B02 after the connection seat 2 is connected to the plate body B02 to prevent the connection seat 2 from being forced back. The undercut tooth 23 and the connection seat 2 can also be processed in an integral molding manner to improve the integrity of the connection between the connection seat 2 and the plate body B02.

[0023] In another embodiment, a cover 4 is further provided on the connection seat 2. The cover 4 is fixed to the connection seat 2 and is used to shield the eccentric wheel 3 exposed to the connection seat 2 to prevent dust and debris from the outside from entering the accommodating chamber 21 and accumulating together. In this embodiment, a positioning hole 24 is provided on the connection seat 2, and a positioning column 41 is integrally formed on the cover 4. The positioning hole 24 and the positioning column 41 can be matched and plugged to achieve the fixation of the cover 4 on the connection seat 2. In order to make the fixing effect of the two better, the positioning hole 24 on the upper part of the connection seat 2 is circular, and the positioning hole 24 on the lower part is square, and the positioning column 41 on the cover 4 is also circular on the upper part and square on the lower part. The positioning column 41 at the lower part of the cover 4 also has a guiding inclined surface 42 to make the installation of the cover 4 on the connection seat 2 smoother.

[0024] When installing the furniture layer support of the utility model, firstly, assembly holes for accommodating the connecting rod 1 and the connecting seat 2 are respectively opened on the plate body A01 and the plate body B02. Then the connecting rod 1 is rotated and screwed into the plate body A01 under the action of the threaded connection. The eccentric wheel 3 is inserted into the accommodating cavity 21 from the rear of the connecting seat 2, and axial positioning is performed by the positioning platform 22 and the positioning block 31. Then the connecting seat 2 is inserted into the plate body B02, so that the buckle joint 11 and the eccentric wheel 3 are buckled together, and the eccentric wheel 3 is rotated to connect the plate body A01 and the plate body B02 together. Finally, the cover 4 is fixed to the connecting seat 2, and the fixing of the plate body A01 and the plate body B02 can be completed. When it is found that the connection between the plate body A01 and the plate body B02 is too tight to generate extrusion stress, the tensile torque generated by the connecting rod 1 on the plate body A01 and the plate body B02 can be eliminated by simply rotating the eccentric wheel 3.

[0025] The above-mentioned specific embodiments are only implementation methods with better technical effects of the utility model. Any structure that is the same or equivalent to the tensioning furniture shelf support of the utility model is within the protection scope of the utility model.
