[0002] There is a type of sofa currently on the market, whose main frame is made of metal, and whose side panels are formed by arranging and assembling stop bars on both sides. The stop bars of the existing sofa are fixed by screws, and the screws are exposed, which makes the installation complicated and the production efficiency low. In addition, the screws are easily touched during use, resulting in a bad user experience. Utility Model Content

[0003] The purpose of the utility model is to provide a sofa with a hidden screw structure to solve the above technical problems.

[0004] To achieve the above-mentioned purpose, the specific technical solution of a sofa with a hidden screw structure of the present invention is as follows:

[0005] A sofa with a hidden screw structure includes a side frame, a leg connecting tube, and a plurality of stop bars, wherein the stop bars are mounted on the side frames, and the leg connecting tube is mounted at the bottom of the side frame. The sofa also includes an L-shaped positioning piece, wherein the inner sides of both sides of the side frame have a card slot, and the L-shaped positioning piece is fixedly connected to both sides of the lower end of the stop bar. The plurality of stop bars are pushed into the card slot in sequence, and the second stop bar is limited by the L-shaped positioning piece of the first stop bar. After the last stop bar is assembled, the leg connecting tube is fixedly mounted at the bottom of the side frame, below the last stop bar.

[0006] Furthermore, the L-shaped positioning piece is a plastic piece.

[0007] Furthermore, the side frame includes a side frame and a transverse frame, and the upper ends of the two side frames are connected by the transverse frame.

[0008] Furthermore, the side frame is an integrated structure.

[0009] The sofa with a hidden screw structure according to claim 1 is characterized in that the slot is arranged on the inner side of the side frame, and the width of the slot matches the width of the stop bar and the L-shaped positioning piece after connection, so that the L-shaped positioning piece can be hidden in the slot.

[0010] Furthermore, the L-shaped positioning member includes a connecting end and a limiting end, the connecting end is arranged on one side of the upper end of the limiting end, the connecting end and the limiting end form an L shape, and the connecting end has one or more fixing holes. The fastener passes through the fixing holes to fix the L-shaped positioning member on both sides of the block bar. After the fixing is completed, the limiting end protrudes from the lower end of the block bar and is used to limit the next block bar so that there is a gap between the block bars.

[0011] Furthermore, the two ends of the foot connecting tube have connecting parts, and the connecting parts have connecting holes. Fasteners pass through the connecting holes to fix the foot connecting tube to the bottom of the side frame.

[0012] Furthermore, it also includes a square positioning piece, which is pressed against the lower end of the stop bar by a fastener to fix it on the inner side of the side frame.

[0013] The sofa with a hidden screw structure according to the claim or the description is characterized in that the fasteners are screws.

[0014] The sofa with a hidden screw structure of the present invention has the following advantages: the present invention slots the side frame, then fixes the L-shaped positioning piece to the stop bar, and then pushes the stop bar into the slot. The stop bar is fixed by the limiting action of the square positioning piece, which optimizes the assembly method of the stop bar, makes the production process simpler, makes the workshop assembly operation more convenient, and shortens the time for locking screws; the external structure is simple, the screws will not be touched, and the customer experience is enhanced.

[0021] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a sofa with a hidden screw structure of the present invention in conjunction with the accompanying drawings.

[0022] like Figure 1-5As shown, a sofa with a hidden screw structure of the present invention includes a side frame 1, a foot connecting tube 2, a stop bar 3, an L-shaped positioning piece 4 and a square positioning piece 5. The stop bar 3 is installed on the side frame 1, and the foot connecting tube 2 is installed at the bottom of the side frame 1. The inner sides of both sides of the side frame 1 are provided with a slot 111, and the L-shaped positioning piece 4 is fixed to both sides of the lower end of the stop bar 3 by fasteners 6. Then, multiple stop bars 3 are pushed into the slot 111 in sequence, and the second stop bar 3 is limited by the L-shaped positioning piece 4 of the first stop bar 3. When the last stop bar 3 is assembled, a square positioning piece 5 is pressed against the lower end of the stop bar 3 by the fastener 6 to fix it to the inner side of the side frame 1 to prevent the stop bar 3 from falling. Finally, the foot connecting tube 2 is fixedly installed at the bottom of the side frame 1, and the last stop bar 3 is assembled below to achieve the screw concealing effect.

[0023] Preferably, the L-shaped positioning member 4 and the square positioning member 5 are plastic members, and the fastener 6 is a screw.

[0024] The side frame 1 includes a side frame 11 and a horizontal frame 12. The upper ends of the two side frames 11 are connected by the horizontal frame 12. The side frame 1 is preferably an integrated structure. The card slot 111 is arranged on the inner side of the side frame 11. The width of the card slot 111 matches the width after the block bar 3 and the L-shaped positioning member 4 are connected, so that the L-shaped positioning member 4 can be hidden in the card slot 111.

[0025] The L-shaped positioning member 4 includes a connecting end 41 and a limiting end 42. The connecting end 41 is located on one side of the upper end of the limiting end 42, forming an L-shape with the limiting end 42. The connecting end 41 has one or more fixing holes 411. The fasteners 6 pass through the fixing holes 411 to fix the L-shaped positioning member 4 to the two sides of the stop bar 3. After the fixation is completed, the limiting end 42 protrudes from the lower end of the stop bar 3, which is used to limit the position of the next stop bar 3, so that there is a gap between the stop bars 3.

[0026] The foot connecting tube 2 has connecting portions 21 at both ends, each with connecting holes 211 therein, for connecting to the side frame 1. After the last block bar 3 is installed, the square positioning piece 5 is inserted into the square notch 22 of the foot connecting tube 2. Then, the fastener 6 is inserted through the connecting holes 211 to secure the foot connecting tube 2 to the bottom of the side frame 1.

[0027] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
