Description

Technical Field

[0001] The utility model relates to the field of table and chair furniture, in particular to a supporting frame module structure. Background Art

[0002] In order to accommodate more tables and chairs in classrooms, conference rooms and other places, tables and chairs are generally integrated into one setting, especially in spaces with stepped structures (of course, this is not limited to flat spaces).

[0003] However, the existing integrated table and chair structure has the problem of being difficult to install. For example, although the integrated table top simplifies the installation of the table top, some of them are long, which increases both the production cost and the transportation cost.

[0004] Of course, there are also single-individual table and chair integrated structures, such as Chinese patent 202320568402.6, which can realize seat integration, but its supporting structure is large in volume, so the transportation cost is high during transportation, and it is not suitable for the structure of folding chairs;

[0005] At the same time, the base area of ​​the supporting structure is relatively large. After the actual installation, a large blind spot for hygiene is likely to appear, which affects cleaning (it also occupies a large space). At the same time, it is also more troublesome to install the seat surface. Utility Model Content

[0006] The main purpose of the utility model is to propose a support frame module structure, aiming to improve the structure of the support frame so that both the chair surface and the desktop can be installed, and the installation is simple, and the body volume is small, easy to install, and good stability.

[0007] To achieve the above-mentioned purpose, the utility model proposes a support frame module structure, comprising an integrally formed foot portion, a connecting portion extending obliquely backward from the foot portion, a supporting portion extending upward from the connecting portion, and an armrest portion extending horizontally between the connecting portion and the supporting portion, wherein a positioning portion is provided between the foot portion and the connecting portion;

[0008] The support frame is a hollow structure.

[0009] The one-piece formed foot, connection part, armrest part and support part can effectively ensure the solidity of the structure. At the same time, the overall structure is small in size, which is convenient for transportation and installation. At the same time, the interference of the frame is effectively avoided during the installation process, and the blind spots of the installation are avoided. At the same time, it is light in weight, which effectively saves the physical strength of the installers during installation. The backrest board is installed between the support parts, the chair board is installed on the positioning part, and the table board is installed on the rear wall of the support part. The installation is simple, which effectively improves the installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0017] In addition, if there are descriptions involving "first" or "second" etc. in the embodiments of the utility model, the descriptions of "first" or "second" etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0018] like Figures 1 to 4As shown, a support frame module structure includes an integrally formed foot portion 11, a connecting portion 12 extending obliquely backward from the foot portion 11, a supporting portion 13 extending upward from the connecting portion 12, and an armrest portion 14 extending horizontally between the connecting portion 12 and the supporting portion 13, wherein a positioning portion 2 is provided between the foot portion 11 and the connecting portion 12;

[0019] The support frame 1 is a hollow structure.

[0020] The solidity of the structure can be effectively ensured by the one-piece formed foot 11, connecting part 12, armrest part 14 and supporting part 13. At the same time, the overall structure is small in size, which is convenient for transportation and installation. At the same time, the interference of the frame is effectively avoided during the installation process, and the blind spots of the installation are avoided. At the same time, it is light in weight, which effectively saves the physical strength of the installer during installation. The backrest board is installed between the supporting parts 13, the chair board is installed on the positioning part 2, and the table board is installed on the rear wall of the supporting part 13. The installation is simple, which effectively improves the installation efficiency.

[0021] Specifically, the positioning portion 2 is fixedly installed between the foot 11 and the connecting portion 12 or pivotally installed between the foot 11 and the positioning portion 2. According to the requirements of the chair board, the chair board can be set to a flip structure or a fixed structure.

[0022] Specifically, the hollow part is installed with a template or a decorative plate, so that the table and chair are more beautiful and can be combined with the wood grain color of the table and chair.

[0023] In the embodiment of the utility model, the foot portion 11, the connecting portion 12, the armrest portion 14 and the supporting portion 13 are respectively provided with a first hollow groove 31, a second hollow groove 32, a third hollow groove 33 and a fourth hollow groove 34. Among them, the fourth hollow groove is used for the backrest board to be inserted and installed, thereby facilitating the stability of the installation.

[0024] Furthermore, a support surface 35 is provided at the lower end of the foot 11, and the foot 11 is gradually reduced in diameter from the lower end upwards, thereby forming a good curvature and having good support.

[0025] In the embodiment of the utility model, the support frame 1 is integrally molded by mold injection molding, integrally welded molding, or integrally extruded aluminum. Aluminum extrusion molding is preferred, which is similar to the process of tube molding, has higher firmness and durability, and the production cost is lower than that of welding and casting.

[0026] Specifically, the foot portion is bent forward, and the connecting portion 12 is bent backward, so as to improve the structural aesthetics. Of course, in actual design, improvements can also be made according to actual needs.

[0027] In the embodiment of the utility model, when the positioning portion 2 is pivotally installed between the foot 11 and the positioning portion 2, a pivot hole 21 is provided between the foot 11 and the positioning portion, and the positioning portion is provided with a rotating portion matched with the pivot hole.

[0028] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
