The present application is described in further detail below in conjunction with fig. 1-6.
Embodiment one:
the embodiment of the application discloses mechanism of preventing turning over of sofa back, refer to fig. 1, and it includes end connecting rod 1 and connecting piece 2, and end connecting rod 1 is provided with two sets of and is located the both ends of connecting piece 2 respectively, and connecting piece 2 is provided with at least two sets of along the length direction interval of end connecting rod 1, does not have two sets of adjacent connecting piece 2 to all can install a set of sofa to the sofa that the multiunit is connected together. One end of the connecting piece 2 is provided with an extending piece 3, the extending piece 3 is used for increasing the stressed area of one side of the sofa backrest, and the stability of the connecting piece 2 is increased.
Referring to fig. 2, foot pads 4 are detachably connected to the bottoms of the bottom link 1, the connecting member 2 and the extension member 3, and the foot pads 4 are preferably made of an elastic material such as rubber pads. The cross sections of the bottom connecting rod 1, the connecting piece 2 and the extending piece 3 are all L-shaped, and the L-shaped structure can ensure the structural strength of the component and can bear larger load.
Referring to fig. 3, the connection member 2 includes a strip-shaped nail 21 and a groove 22, the strip-shaped nail 21 and the groove 22 are each elongated L-shaped plates, and the strip-shaped nail 21 and the groove 22 are fitted to each other. The connecting nail 211 is fixedly connected with the nail piece 21, and the connecting nail 211 and the nail piece 21 can be fixed through threaded fit or through welding. The grooved piece 22 is provided with a groove in a penetrating manner, the groove comprises an insertion part 222 and a limiting part 221, the insertion part 222 is inclined towards one side, the limiting part 221 faces vertically, and the width of the limiting part 221 is the same as the diameter of the connecting nail 211. During installation, the two ends of the grooved piece 22 are fixed on the bottom connecting rod 1 through the fastening piece, then the connecting nail 211 is inserted into the inserting part 222 and moves to the limiting part 221 to limit, and finally the two ends of the nailed piece 21 are fixed on the bottom connecting rod 1 through the fastening piece. When the connection pins 211 are in the stopper 221, the belt pin 21 and the grooved member 22 are fixed, and the belt pin 21 and the grooved member 22 can be reduced from sliding in the own length direction, thereby increasing the stability of the connection member 2.
Referring to fig. 3 and 4, each set of connecting members 2 corresponds to two extending members 3, one extending member 3 being welded or integrally formed with the nailed member 21, and the other extending member 3 being welded or integrally formed with the grooved member 22.
Referring to fig. 3 and 4, a stabilizer 5 is further disposed between two adjacent sets of connecting members 2, and the stabilizer 5 is also a long plate with an L-shaped cross section. One end of the stabilizing member 5 is detachably connected to the nailed member 21, and the other end of the stabilizing member 5 is detachably connected to an adjacent set of grooved members 22. The stabilizing piece 5 can increase the connection between the adjacent connecting pieces 2, increase the contact area with the ground, and increase the stability between the adjacent connecting pieces 2 while guaranteeing the anti-overturning effect of the extension piece 3.
The implementation principle of the first embodiment is as follows:
the bottom connecting rod 1 and the connecting piece 2 form a stable structure through the fastening piece, the extending piece 3 at one end of the connecting piece 2 can increase the contact area with the ground, and when the center of gravity of the sofa backrest moves backwards, the extending piece 3 can provide the functions of supporting and stabilizing the integral structure. The stabilizing members 5 between adjacent connecting members 2 can further increase the supporting effect of the extension members 3 and enhance the stability between adjacent extension members 3.
Embodiment two:
the difference between this embodiment and the first embodiment is that: the extending piece 3 is movably connected with the connecting piece 2, in particular the extending piece 3 is rotatably connected with the connecting piece 2, and the extending piece 3 can be detached from the connecting piece 2.
Referring to fig. 5, the extension member 3 is provided with a relief groove 31, and the relief groove 31 can reduce interference between the extension member 3 and the bottom link 1 when the extension member 3 rotates. The extension piece 3 is close to the fixed butt portion 32 that is provided with of one end of connecting piece 2, butt portion 32 offsets with connecting piece 2, and when the focus of sofa back moved backward, extension piece 3 was far away from connecting piece 2, and stability is poor more, and butt portion 32 can increase the contact of extension piece 3 and connecting piece 2, can keep preventing the effect of turning over when guaranteeing extension piece 3 atress again can keep original form.
Referring to fig. 6, when the extension member 3 rotates around the rotation axis, a certain included angle is formed between the extension member 3 and the connection member 2, and the included angle a ranges from 0 ° to 60 °, when a is 0 °, the two extension members 3 are attached to each other, the extension member 3 and the connection member 2 are in the same direction, at this time, the extension member 3 extends outwards to the greatest extent, the stability against turning is the best, but the space occupied by the extension member 3 is the greatest. When a is 60 °, the two extension pieces 3 are far away from each other, and the space occupation of the extension pieces 3 is small, but the anti-rollover stability of the extension pieces 3 is poor. When A is 30 degrees, the space occupation of the extension piece 3 is moderate, and the anti-overturning performance of the extension piece 3 is also good.
The implementation principle of the second embodiment is as follows:
the extension piece 3 can adapt to different application scenes by reverse rotation, the smaller the angle between the extension piece 3 and the connecting piece 2 is, the more the extension piece 3 outwards extends, the better the anti-overturning effect is, the larger the angle is, and the smaller the space occupation rate of the extension piece 3 is.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
