[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0021] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0022] Example 1

[0023] See Figures 1 to 5 As shown, the push-pull sofa pneumatic storage bracket involved in this embodiment includes a lower connecting crossbar 1 and an upper connecting crossbar 2 located above the lower connecting crossbar. A short support rod 3 near the front end and a gas spring 4 near the rear end are provided between the lower connecting crossbar 1 and the upper connecting crossbar 2. A long support rod 5 with one end hinged to the lower connecting crossbar and the other end hinged to the upper connecting crossbar is provided between the gas spring 4 and the short support rod 3. One end of the short support rod 3 and the gas spring 4 are both hinged to the lower connecting crossbar and the other end is hinged to the upper connecting crossbar. It also includes a slide rail 6 that extends linearly along the length extension direction of the lower connecting crossbar 1. A slide rail groove 7 is provided on the slide rail 6. At least two rollers 8 that roll inside the slide rail groove 7 are rotatably connected to the lower connecting crossbar 1.

[0024] In this embodiment, by adding a long support rod 5 with one end hinged to the lower connecting crossbar and the other end hinged to the upper connecting crossbar between the gas spring 4 and the short support rod 3, the upper connecting crossbar 2 can tilt up or down relative to the lower connecting crossbar 1 while the gas spring 4 is extending and retracting. The long support rod 5 not only provides auxiliary transmission but also plays a role in local support and reinforcement, making the overall stability of the support frame higher.

[0025] Example 2

[0026] See Figures 1 to 5 As shown, the push-pull sofa pneumatic storage bracket involved in this embodiment is further configured based on embodiment 1, wherein the pulley 8 includes a wheel axle 81 and a wheel 82, the wheel 82 is rotatably connected to the wheel axle 81, one end of the wheel axle 81 is fixedly connected to the lower connecting crossbar 1, and the other end is provided with a spherical groove 83;

[0027] The bottom of the slide rail groove 7 is provided with an adjustment groove 71 that matches the pulleys one by one. An adjustment piece 9 for reversible installation is embedded in the adjustment groove 71. A spring hole 91 is provided in the center of the adjustment piece 9. A spring piece 92 is provided in the spring hole 91. A connecting part 93 is provided between the spring piece 92 and the adjustment piece 9 to create a gap between them. A spherical protrusion 94 is pressed on the spring piece 92 and can be fitted into the spherical groove 83.

[0028] Furthermore, the bottom of the adjustment groove 9 is provided with clearance holes 95 for left and right through slide rails, and the clearance holes 95 can also be used for embedding the spherical protrusion 94.

[0029] Furthermore, the same slide rail groove 7 is provided with no less than three pulleys 8, and the distance between two adjacent pulleys 8 is equal.

[0030] In this embodiment, the lower connecting crossbar 1 slides relative to the slide rail 6 in two modes: a stepped adjustment mode with a tactile feedback and a stepless adjustment mode without a tactile feedback. The former involves exposing the spherical protrusion 94 on the spring piece 92 and extending it beyond the opening of the adjustment groove 71. When the pulley 8 moves back and forth, the elastic spherical protrusion 94 engages with the spherical groove 83 at one end of the axle 81, creating an intermittent pause. The latter involves flipping the adjustment piece 9 and hiding it within the adjustment groove 71 until the spherical protrusion 94 is no longer exposed (nor extending beyond the opening of the adjustment groove 71). When the pulley 8 moves back and forth, the spherical protrusion 94 no longer contacts the axle 81, thus eliminating the intermittent pause.

[0031] By opening the clearance hole 95, when the spring piece 92 faces away from the pulley 8, the spherical protrusion 94 is embedded in the clearance hole 95, so as to ensure that the end face of the adjusting piece 9 can still be in contact with the bottom of the adjusting groove 71, and avoid extending out of the groove and interfering with the rolling of the pulley 8.

[0032] Example 3

[0033] See Figures 1 to 5 As shown, the push-pull sofa pneumatic storage bracket involved in this embodiment is further configured, based on embodiment 2, with two adjacent notches 96 spaced at an angle of 180° around the edge of the adjusting piece 9.

[0034] In this embodiment, the notch 96 allows fingers to be inserted to easily remove the adjustment piece 9 from the adjustment groove 71 for flipping or replacement.

[0035] The push-pull sofa pneumatic storage bracket involved in this utility model, through the centrally located long support rod that provides support and transmission, ensures that the upper cabinet panel has a stronger load-bearing capacity and is safer and more stable to use while opening and closing; in addition, the overall bracket structure can move back and forth relative to the slide rail, so that when it is assembled with a high armrest and high back sofa, it avoids interference and allows for freer and more flexible opening and closing; the overall bracket structure can also be adjusted back and forth with stepless or stepped position relative to the slide rail, and both adjustment modes can be selected and used, which is highly adaptable, has complete functions, and is highly practical.
