Description

Technical Field

[0001] This utility model relates to the field of table leg technology, and in particular to a table frame. Background Technology

[0002] In traditional furniture, table legs and crossbeams are key components of the supporting and load-bearing structure. Currently, the common method of connecting table legs and crossbeams mainly uses connecting brackets, which are directly connected to the table legs with screws. Screw holes are drilled in the table legs or connecting brackets, and the screws are used to fasten the two together. However, drilling screw holes in the table legs or connecting brackets requires precise machining and positioning, increasing the manufacturing difficulty and affecting the aesthetics. Furthermore, the drilling of screw holes may weaken the structural strength of the table legs or connecting brackets, affecting the overall load-bearing capacity. Therefore, it is necessary to improve the existing technology to solve these problems. Utility Model Content

[0003] The purpose of this utility model is to provide a table frame that solves the problem in the prior art where the connecting brackets and table legs are directly connected by screws, which increases the processing difficulty and affects the overall load-bearing capacity.

[0004] To achieve the above objectives, this utility model provides a table frame, including a connecting bracket, table legs, an outer support assembly, and a crossbeam. The table legs are provided with through cavities. The connecting bracket includes a table leg connecting section and a crossbeam connecting section that are connected together and form an L-shape. The table leg connecting section is inserted into the through cavity, and the end of the crossbeam connecting section is connected to the crossbeam. The table leg connecting section is provided with two outer support blocks, and a sliding groove is formed between the two outer support blocks. The sliding groove includes a narrowing section that narrows towards the end of the table leg connecting section. The outer support assembly includes a sliding support block that is slidably connected in the sliding groove and a feeding structure that moves the sliding support block. When the feeding structure moves the sliding support block towards the end of the table leg connecting section within the narrowing section, the sliding support block pushes the two outer support blocks outward, thereby fixing the table legs to the table leg connecting section of the connecting bracket.

[0005] Furthermore, the external support assembly includes a feed screw, and the sliding support block is provided with a threaded through hole. After the feed screw extends into the sliding groove, it is threadedly connected to the threaded through hole, and the screw head of the feed screw is always pushed against by the end of the table leg connecting section.

[0006] Furthermore, the outer support assembly also includes a limiting washer, which is fitted onto the feed screw and located between the screw head of the feed screw and the outer support block.

[0007] Furthermore, the sliding support block is cylindrical.

[0008] Furthermore, a deformation through hole is provided at one end of the outer support block near the crossbeam connection section, and the orientation of the deformation through hole is perpendicular to the outer support direction of the outer support block.

[0009] Furthermore, a groove is provided at the end of the outer support block away from the crossbeam connection section, and the direction of the groove is parallel to the outer support direction of the outer support block.

[0010] Furthermore, the table frame includes connecting screws, a connecting screw hole at the end of the crossbeam connecting section, a through hole in the crossbeam, a connecting washer between the screw head of the connecting screw and the crossbeam, and the connecting screw is threaded into the connecting screw hole after passing through the through hole; the crossbeam connecting section is provided with a positioning protrusion that fits into the through hole, and the positioning protrusion is provided with a guide bevel.

[0011] Furthermore, the table leg connecting section includes a support end near one end of the crossbeam connecting section. The cross section of the support end matches the cross section of the through cavity, so that after the table leg connecting section is inserted into the through cavity, the support end can support the table leg to prevent the table leg from wobbling at the support end.

[0012] Furthermore, the table frame includes foot covers, which are installed on the bottom of the table legs. The foot covers are provided with mounting blocks that fit into the through cavity. The mounting blocks are inserted into the through cavity, and the foot covers are threadedly connected with adjusting pads.

[0013] Furthermore, this type of table frame includes two table legs, both of which are connected to the crossbeam by means of connecting brackets and external support components, and the two table legs are distributed in a V-shape.

[0014] The table frame provided by this utility model, compared with the prior art, can quickly fix and disassemble the table legs by moving the sliding support block in the sliding groove, without the need to open screw holes on the table legs or connecting brackets, which greatly simplifies the processing process, reduces the processing difficulty, improves the aesthetics of the overall structure, and effectively improves the load-bearing capacity and stability of the overall structure.

[0022] The present invention will be described in detail below with reference to specific embodiments.

[0023] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0024] This utility model provides a table frame, such as Figures 1 to 5As shown, it includes a connecting code 1, table legs 2, an outer support assembly 3, and a crossbeam 4. The table legs 2 are provided with a through cavity 21. The connecting code 1 includes a table leg connecting section 11 and a crossbeam connecting section 10 that are connected together and form an L-shape. The table leg connecting section 11 is inserted into the through cavity 21, and the end of the crossbeam connecting section 10 is connected to the crossbeam 4. The table leg connecting section 11 is provided with two outer support blocks 111, and a sliding groove 112 is formed between the two outer support blocks 111. The sliding groove 112 includes a narrowing section 1121 that gets narrower closer to the end of the table leg connecting section 11. The outer support assembly 3 includes a sliding support block 32 that is slidably connected in the sliding groove 112 and a feeding structure that moves the sliding support block 32. When the feeding structure moves the sliding support block 32 towards the end of the table leg connecting section 11 in the narrowing section 1121, the sliding support block 32 pushes the two outer support blocks 111 outward so that the table legs 2 are fixed to the table leg connecting section 11 of the connecting code 1. Based on the above structural design, the table leg 2 can be quickly fixed and disassembled by moving the sliding support block 32 within the sliding groove 112. There is no need to drill screw holes on the table leg 2 or the connecting bracket 1, which greatly simplifies the processing process, reduces the processing difficulty, and also improves the aesthetics of the overall structure, effectively improving the load-bearing capacity and stability of the overall structure.

[0025] In this embodiment, the outer support assembly 3 includes a feed screw 31 and a sliding support block 32 with a threaded through hole 321. The feed screw 31 extends into the sliding groove 112 and is threaded into the threaded through hole 321. The screw head of the feed screw 31 is always pushed against the end of the table leg connecting section 11. During installation, the table leg 2 is first put onto the table leg connecting section 11, and then the feed screw 31 is turned (of course, since the table leg 2 is relatively long, a special extended screwdriver is needed to pass through the table leg 2 to reach the feed screw 31). At the same time, the sliding support block 32 moves towards the end of the table leg connecting section 11, spreading the two outer support blocks 111 outward, thus fixing the table leg 2 onto the table leg connecting section 11, thereby forming a stable mechanical lock, effectively preventing relative movement between the table leg 2 and the table leg connecting section 11, and improving the connection stability.

[0026] In this embodiment, the table leg connecting section 11 includes a support end 115 near the crossbeam connecting section 10 and an outer support end 116 away from the crossbeam connecting section 10. The cross section of the support end 115 matches the cross section of the through cavity 21 so that after the table leg connecting section 11 is inserted into the through cavity 21, the support end 115 can support the table leg 2 to prevent the table leg 2 from wobbling at the support end 115, thus achieving a more stable connection between the table leg connecting section 11 and the table leg 2. The cross section of the outer support end 116 is not larger than the cross section of the through cavity 21. More preferably, the cross section of the outer support end 116 is smaller than the cross section of the through cavity 21 so that the table leg connecting section 11 can be more easily inserted into the through cavity 21.

[0027] In this embodiment, the outer support assembly 3 further includes a limiting washer 33, which is sleeved on the feed screw 31 and located between the screw head of the feed screw 31 and the outer support block 111. The limiting washer 33 can increase the contact area between the screw head of the feed screw 31 and the outer support block 111, thereby dispersing the concentrated pressure of the feed screw 31 on the outer support block 111, and at the same time preventing the screw head of the feed screw 31 from entering the sliding groove 112, ensuring the stability of the sliding support block 32 during the sliding process.

[0028] In this embodiment, the sliding support block 32 is cylindrical, which helps to reduce friction and wear during the sliding process, extend the service life of the sliding support block 32, and also ensures stability during the sliding process.

[0029] In this embodiment, a deformation through hole 113 is provided at one end of the outer support block 111 near the crossbeam connecting section 10, and the orientation of the deformation through hole 113 is perpendicular to the outward support direction of the outer support block 111. The provision of the deformation through hole 113 makes the outer support block 111 more prone to deformation, thereby making it easier for the end of the outer support block 111 to be pushed outward.

[0030] In this embodiment, a groove 114 is provided at the end of the outer support block 111 away from the crossbeam connecting section 10, and the direction of the groove 114 is parallel to the outward support direction of the outer support block 111. The groove 114 reduces the amount of material used in the outer support block 111, while ensuring that the outer support block 111 has sufficient contact area to cooperate with the sliding support block 32, and also ensures that the outer support block 111 provides sufficient supporting force to the table leg 2 when it is outwardly supported, ensuring that it is sufficiently strong after assembly; it also achieves the weight reduction of the outer support block 111, effectively reducing production costs.

[0031] In this embodiment, the table frame also includes connecting screws 5, a connecting screw hole 12 is provided at the end of the crossbeam connecting section 10, a through hole 41 is provided on the crossbeam 4, a connecting washer 51 is provided between the screw head of the connecting screw 5 and the crossbeam 4, and the connecting screw 5 passes through the through hole 41 and is threaded into the connecting screw hole 12. Through the above structural design, a stable connection between the connecting screw 1 and the crossbeam 4 is achieved, ensuring the stability and reliability of the connection.

[0032] In this embodiment, the crossbeam connecting section 10 is provided with a positioning protrusion 13 that fits into the through hole 41, and the positioning protrusion 13 is provided with a guide slope 14. Through the above structural design, the crossbeam 4 can be installed quickly and accurately, reducing assembly errors and improving assembly efficiency.

[0033] In this embodiment, the table frame also includes foot covers 6, which are provided with mounting blocks 61 that fit into the through cavity 21, and adjustable feet 62 are threadedly connected to the foot covers 6. By adjusting the height of the feet 62, the tabletop can be kept level, reducing tabletop wobbling or tilting caused by uneven ground.

[0034] In this embodiment, the table frame includes two table legs 2, both of which are connected to the crossbeam 4 by means of connecting brackets 1 and external support components 3, and the two table legs 2 are distributed in a V-shape.

[0035] In summary, this type of table frame can solve the problem of the existing technology where the connecting brackets and table legs are directly connected by screws, which increases the processing difficulty and affects the overall load-bearing capacity.

[0036] Where there is no conflict, the above embodiments and features can be combined with each other.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
