Description

Technical Field

[0001] The utility model relates to the field of furniture, and particularly to a furniture splicing cylinder. Background Art

[0002] In furniture production, multiple wooden sticks or strips are often used to surround and fit together to form a cylinder. However, for the cylinder produced by this splicing method, due to thermal expansion and contraction during use, the wooden sticks or strips are likely to move away from each other, resulting in cracking of the cylinder.

[0003] In view of this, the inventor of this case conducted in-depth research on the above problems, and thus this case was born. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a furniture splicing cylinder that can avoid cracking of the cylinder.

[0005] In order to achieve the above purpose, the utility model adopts such a technical solution:

[0006] A furniture splicing cylinder includes a plurality of splicing rods. One end of each splicing rod is provided with a splicing groove, and the other end of each splicing rod has a splicing portion that matches the splicing groove. The splicing rods are sequentially connected end to end to form a cylinder.

[0007] Preferably, the horizontal cross-section of the splicing groove is triangular.

[0008] Preferably, the width of the splicing groove on the side away from the center of the cylinder is greater than the width on the side close to the center of the cylinder.

[0009] Preferably, the length of the splicing rod on the side close to the center of the cylinder is greater than the length on the side away from the center of the cylinder.

[0010] Preferably, a deformation portion is provided at a position of the splicing rod corresponding to the splicing groove close to the center of the cylinder.

[0011] Preferably, a fixing glue layer is provided between the splicing groove and the splicing portion.

[0012] By adopting the foregoing design scheme, the beneficial effect of the utility model is as follows: The splicing groove and the splicing portion are used in cooperation to splice a plurality of splicing rods into a cylinder. On the one hand, it can ensure that the splicing rods are closely fitted. On the other hand, even if the splicing rods expand or contract thermally, the splicing groove and the splicing portion also expand or contract accordingly, making the connection between the splicing rods closer and not separating, effectively solving the problem of cracking of the splicing cylinder.

[0017] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0018] As Figure 1 - Figure 2 shown, a furniture splicing cylinder includes a plurality of splicing rods 10. One end of each splicing rod 10 is provided with a splicing groove 11, and the other end of each splicing rod 10 has a splicing part 12 that matches the splicing groove 11. The splicing rods 10 are sequentially connected end to end to form a cylinder.

[0019] In this embodiment, the cross-section of the splicing rod 10 without the splicing groove 11 is rectangular. A splicing groove 11 is opened at one end in the length direction of the splicing rod 10, and the other end in the length direction of the splicing rod 10 is directly used as the splicing part 12 for cooperation with the splicing groove 11, so that only one end of the splicing rod 10 needs to be processed, improving the processing efficiency and saving labor costs.

[0020] In this embodiment, the horizontal cross-section of the splicing groove 11 is triangular, and the width of the splicing groove 11 on the side away from the center of the cylinder is greater than the width on the side close to the center of the cylinder. The length of the splicing rod 10 on the side close to the center of the cylinder is greater than the length on the side away from the center of the cylinder. The horizontal cross-section of the splicing groove 11 is set to be triangular to increase the contact surface between the splicing rods 10, and the structural force of the triangle is greater than that of the plane structure, making the splicing more firm and avoiding cracking during the splicing process.

[0021] In this embodiment, a deformation part 13 is provided at the position of the splicing rod 10 corresponding to the splicing groove 11 close to the center of the cylinder. By providing the deformation part 13, when the splicing rods 10 expand and contract due to heat or cold during splicing or subsequent use, the internal angle of the cylinder is too sharp and explodes, ensuring the overall firmness of the splicing cylinder.

[0022] As a preferred method of this embodiment, a fixing glue layer (not shown in the figure) is provided between the splicing groove 11 and the splicing part 12. The fixing glue layer refers to applying conventional glue on the splicing groove 11 and / or the splicing part 12 to increase the fixation of the splicing rods 10.

[0023] In summary, by using the splicing groove 11 and the splicing portion 12 to cooperate with each other to splice a plurality of splicing rods 10 into a cylinder, on the one hand, it can ensure that the splicing rods 10 are closely fitted, and on the other hand, even if the splicing rods 10 expand or contract due to heat or cold, the splicing groove 11 and the splicing portion 12 will also expand or contract accordingly, making the connection between the splicing rods 10 tighter and not separating, effectively solving the problem of cracking of the spliced cylinder.

[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
