DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model 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 in 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.

[0020] The utility model discloses a sofa bottom locking mechanism. Figure 1-4 A sofa bottom locking mechanism is used for a first sofa 1 and a second sofa 2. A first shell 3 is fixedly connected to the left side of the bottom of the first sofa 1, and a squeezing mechanism 4 is arranged inside the first shell 3. A second shell 5 is fixedly connected to the right side of the bottom of the second sofa 2. The right side of the second shell 5 is in contact with the left side of the first shell 3, and a locking mechanism 6 used in conjunction with the squeezing mechanism 4 is arranged inside the second shell 5.

[0021] The locking mechanism 6 includes two locking blocks 601, two connecting rods 602, a pull plate 603 and two springs 604. The two locking blocks 601 are inserted into the interior of the second shell 5. The two connecting rods 602 are respectively fixedly connected to the bottom ends of the corresponding locking blocks 601, and the bottom ends of the connecting rods 602 pass through the second shell 5. The pull plate 603 is fixedly connected to the bottom ends of the two connecting rods 602. The two springs 604 are respectively sleeved on the outside of the corresponding connecting rods 602, and the two ends of the spring 604 are respectively connected to the second shell 5 and the pull plate 603.

[0022] Reference Figure 2 and Figure 4 The extrusion mechanism 4 includes a threaded rod 401, a movable plate 402 and two extrusion blocks 403. The threaded rod 401 is threadedly connected to the first shell 3, and the left end of the threaded rod 401 penetrates into the interior of the first shell 3. The movable plate 402 is slidably connected to the interior of the first shell 3, and the right side of the movable plate 402 is rotatably connected to the left end of the threaded rod 401. The two extrusion blocks 403 are both penetrated and connected to the left side of the movable plate 402; a locking port 7 for use with a locking block 601 is opened at the bottom end of the extrusion block 403, and the top end of the locking block 601 penetrates into the locking port 7.

[0023] By adopting the above technical solution, after the threaded rod 401 is rotated to move the extruding block 403 into the interior of the second housing 5, the locking block 601 can be inserted into the locking opening 7 on the extruding block 403 through the spring 604, so that the extruding block 403 can be locked, and the first sofa 1 and the second sofa 2 are more stable when used together, and are not easily separated by external force.

[0024] Reference Figure 3 A plurality of sockets 8 for use with the extrusion block 403 are provided on the side where the first shell 3 and the second shell 5 are close to each other, and the left end of the extrusion block 403 penetrates into the interior of the second shell 5 through the socket 8.

[0025] By adopting the above technical solution, the extrusion block 403 can be easily inserted into the second housing 5 when it moves to the left through the socket 8, so that the first sofa 1 and the second sofa 2 can be locked easily.

[0026] Reference Figure 2 and Figure 3 The bottom end of the extrusion block 403 and the upper end of the locking block 601 are in a slope shape that cooperate with each other.

[0027] By adopting the above technical solution, when the extrusion block 403 contacts the locking block 601 , the locking block 601 can be squeezed to drive it to move downward, and the spring 604 can be stretched to facilitate the subsequent locking of the extrusion block 403 .

[0028] Reference Figure 1 The bottoms of the first sofa 1 and the second sofa 2 are both fixedly connected with a plurality of supporting legs 9 .

[0029] By adopting the above technical solution, the first sofa 1 and the second sofa 2 are made more stable when in use by the supporting legs 9 .

[0030] Working principle: When the utility model is in use, when the first sofa 1 and the second sofa 2 need to be used together, the threaded rod 401 only needs to be rotated to push the moving plate 402 to move leftward. The moving plate 402 moves leftward and pushes the extrusion block 403 to move leftward, so that the extrusion block 403 is inserted into the interior of the second shell 5 through the socket 8 and squeezes the locking block 601. When the locking block 601 is squeezed, the pulling plate 603 is driven downward through the connecting rod 602. When the pulling plate 603 moves downward, the spring 604 is stretched. When the moving plate 402 contacts the left inner wall of the first shell 3, the threaded rod 401 is stopped from rotating. At this time, the locking block 601 is just located on the extrusion block 403. The locking opening 7 and the extrusion force on the locking block 601 disappear, so that the elastic force of the spring 604 can drive the locking block 601 to move up and insert into the locking opening 7, and then the extrusion block 403 can be locked, so that the first sofa 1 and the second sofa 2 are more stable when used together, and it is not easy to separate the first sofa 1 and the second sofa 2 under the action of external force. When the first sofa 1 and the second sofa 2 need to be used separately, it is only necessary to pull the pull plate 603 to move the locking block 601 out of the first sofa 1, and then rotate the threaded rod 401 in the opposite direction to move the extrusion block 403 back into the first shell 3, so that the first sofa 1 and the second sofa 2 can be used separately.

[0031] When the utility model is used, when the first sofa 1 and the second sofa 2 are used together, the first sofa 1 and the second sofa 2 can be locked, so that the first sofa 1 and the second sofa 2 are not easily separated under the action of external force during the combined use period, thereby ensuring the use effect of the first sofa 1 and the second sofa 2 when used together.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
