Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 and 2, the present embodiment provides a quick-assembly sofa support frame, which includes a frame 1, support legs 2 for supporting the frame 1, and first screws 3 for connecting the frame 1 and the support legs 2.

To distribute the supporting pressure exerted by the supporting leg 2. A support plate 4 extending outside the support leg 2 in the horizontal direction is fixedly provided on one side of the support leg 2 near the frame 1. By providing the support plates 4 on the support legs 2, the support area of the frame 1 is increased, and the pressure of the frame 1 to the support legs 2 is more dispersed.

Referring to fig. 2 and 3, at least one first through hole 7 is formed in the support plate 4 or the support leg 2, and a first threaded hole 8 corresponding to the first through hole 7 is formed in the frame 1. When the support leg 2 is connected with the frame 1, the first screw 3 passes through the first through hole 7 to be in threaded connection with the first threaded hole 8, so that the support leg 2 and the support plate 4 are fixedly connected with the frame 1.

However, before fixing the support leg 2 to the frame 1, the first through hole 7 and the first screw hole 8 need to be aligned. In order to ensure the stability of the reinforcement, the number of the first threaded holes 8 is generally four, and the number of the corresponding first through holes 7 is also four. Therefore, the first through holes 7 and the first threaded holes 8 are subjected to hole alignment, so that the number of the holes is large, and the operation and the work are complicated.

In the hole aligning process, if the first through hole 7 and the second threaded hole 8 are in dislocation after hole aligning, when the first screw 3 passes through the first through hole 7 and is in threaded connection with the second threaded hole 8, the inclination angle of the axis of the first screw 3 relative to the axis of the second threaded hole 8 is easy to occur, so that the phenomenon that the first screw 3 is half blocked when being screwed in the screwing process of the first screw 3 occurs.

Please refer to fig. 3 and fig. 4, in order to avoid the above-mentioned technical problems. The utility model provides a fast-assembling sofa support frame, including frame 1 and be used for supporting leg 2 of frame 1, and connect frame 1 and the first screw 3 of supporting leg 2, fixed mounting has the lug 5 (for example triangle-shaped, semi-circular, square, pentagon etc.) that the horizontal cross-section is noncircular on the supporting leg 2, offer on the frame 1 with the recess 6 of lug 5 looks adaptation, when lug 5 inserts recess 6, first through-hole 7 is coaxial with first screw hole 8 that corresponds, first screw 3 passes first through-hole 7 and the tattoo a8 threaded connection that the screw corresponds this moment.

When the support leg 2 and the frame 1 need to be fixedly installed, only the lug 5 needs to be inserted into the groove 6, so that the lug 5 is completely matched with the groove 6, and the lug 5 cannot rotate relative to the groove 6 at this time, namely the support leg 2 cannot rotate relative to the frame 1 because the horizontal section of the lug 5 is non-circular; meanwhile, each first through hole 7 corresponds to the corresponding first threaded hole 8, and at the moment, only the first screw 3 passes through the first through hole 7 to be in threaded connection with the threaded hole 8, and the first through hole 7 and the corresponding threaded hole 8 do not need to be subjected to hole matching operation for many times, so that the assembly efficiency is improved.

Referring to fig. 3, the protrusion 5 is inserted into the recess 6 for convenience. The bump 5 is prismatic.

The metal sofa underframe in the traditional sense is generally formed by combining welding, and the shape of the underframe cannot be automatically adjusted according to the requirements after welding, for example, the length or the width of the underframe is changed.

Please refer to fig. 2, 3 and 5, in order to solve the above-mentioned technical problems. The frame 1 comprises a section bar 11, an adapter 12 for connecting adjacent section bars 11, and a second screw 13 for fixing the adapter 12 and the section bar 11, wherein the adapter 12 comprises a connecting block 121, a plug 122 is fixedly arranged on the side surface of the connecting block 121, and a jack 111 for inserting the plug 122 is formed at one end, close to the adapter 12, of the section bar 11.

The frame 1 is assembled by splicing by the plug 122 on the adapter 12 matching with the jack 111 of the section bar 11. When the shape of the frame 1 needs to be changed, only the adapter 12 and the section bar 11 need to be disassembled, then the section bar 11 with the corresponding required length is replaced, and then a new section bar 11 is spliced into the frame 1 through the adapter 12.

Referring to fig. 3 and 4, the plug 122 is inserted into the jack 111 for convenience. The side of the plug 122 remote from the connection block 121 is provided with a chamfer.

Please refer to fig. 3 and 5, which are views for reinforcing the connection of the adapter 12 to the profile 11. The plug 122 is provided with two second threaded holes 123 along the vertical direction, the profile is provided with second through holes 112 corresponding to the second threaded holes along the vertical direction, when the plug 122 is completely inserted into the jack 111, the second threaded holes 123 and the second through holes 112 are coaxial, and the second screws 13 penetrate through the second through holes 112 and are in threaded connection with the second threaded holes 123.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
