[0023] The following is only a preferred embodiment of the present invention, and does not limit the scope of the present invention.

[0024] Embodiment: As shown in Attachments Figure 1 , 2 , 3, 4, 5 and Attachment Figure 6 As shown, a height-adjustable suspended ceiling suspension device includes a frame unit 1 for fixing the suspended ceiling A on the ceiling B, a chute unit 2 arranged on the wall C and used for connecting the frame unit 1, and a stud unit 3 arranged on the chute unit 2 and used for adjusting the vertical position of the frame unit 1 and capable of self-locking.

[0025] In this embodiment, the frame unit 1 is a suspension device built by horizontally and vertically fixing a plurality of keels, generally made of light steel. The light steel keels used in the suspended ceiling keels include load-bearing keels, cladding keels, hanging pieces, hanging parts, plug-in parts, load-bearing keel connectors, cladding keel connectors, and suspenders. The main and secondary keels are light steel keels, and each keel can be easily disassembled and restored. The suspended ceiling keels and accessories are made of galvanized steel sheet as raw materials, and are thin-walled steel sections produced by cold bending process, rolled and formed with a national standard 1.5 mm thick galvanized steel sheet, and hot-dip galvanized on the surface, with a galvanized amount reaching 120 g / m 2 Above. The size deviation of each keel should meet the standard that the bending width should not be less than 5.0 mm and the bending height should not be less than 3.0 mm.

[0026] In addition, the main body of the chute unit 2 is a U-shaped steel, which has the characteristics of large pressure resistance, long support time, easy installation and not easy to deform. The single weight of the chute unit 2 is above 40 kg / m to ensure sufficient strength to support the frame unit 1.

[0027] In addition, the frame unit 1 is also connected to the chute unit 2, and through the adjustment of the stud unit 3 arranged on the chute unit 2, the frame unit 1 can be finely adjusted up and down, so as to adjust the position of the suspended ceiling A.

[0028] The frame unit 1 includes a suspension rod 101 disposed on the suspended ceiling A and connected to the chute unit 2, and an internal thread hole 102 disposed on the suspension rod 101; the chute unit 2 includes a C-shaped groove body 201 for inserting and installing the suspension rod 101, and a clamping groove portion 202 disposed on the inner side surface of the C-shaped groove body 201 for vertically fixing the stud unit 3; the stud unit 3 includes a threaded column 301 disposed on the C-shaped groove body 201 and screwed into the internal thread hole 102, a smooth column portion 302 disposed on the bottom surface of the threaded column 301 for connecting the clamping groove portion 202, and a rotating disk portion 303 disposed on the bottom surface of the smooth column portion 302.

[0029] In this embodiment, the C-shaped groove body 201 is a hot-rolled section steel, and its cross-section perpendicular to the extending direction is in a "C" shape for clamping the suspension rod 101. A threaded clamping device is prefabricated in the C-shaped groove body 201 for fixing the suspension rod 101 thereon and enabling the suspension rod 101 to move up and down inside the C-shaped groove body 201.

[0030] In addition, the threaded column 301 is rotatably disposed in the C-shaped groove body 201. A device similar to a bearing is disposed in the C-shaped groove body 201 to support the threaded column 301. The threaded column 301 is screwed into the internal thread hole 102, and through rotation, the technical effect that the suspension rod 101 realizes a fixed height and can be finely adjusted up and down is achieved.

[0031] In addition, the clamping groove portion 202 supports the smooth column portion 302, thereby supporting the threaded column 301. And the smooth column portion 302 can rotate in the clamping groove portion 202. The rotating disk portion 303 is disposed on the bottom surface of the smooth column portion 302 and facilitates rotating the smooth column portion 302. At the same time, a device is additionally provided in the rotating disk portion 303 for adjusting the clamping manner between the smooth column portion 302 and the clamping groove portion 202, which is convenient for subsequently finely adjusting the height of the suspension rod 101.

[0032] The clamping groove portion 202 includes a cylinder body 202a sleeved on the smooth column portion 302, and an annular groove body 202b disposed on the inner side surface of the cylinder body 202a for supporting the smooth column portion 302; the smooth column portion 302 includes a smooth column body 302a disposed in the cylinder body 202a, and a sliding ring 302b disposed on the smooth column body 302a and clamped in the annular groove body 202b; the rotating disk portion 303 includes a rotating column body 303a disposed on the bottom surface of the smooth column body 302a, and a rotating disk 303b disposed on the bottom surface of the rotating column body 303a.

[0033] In this embodiment, the smooth cylinder 302a can slide freely in the cylinder 202a. However, a single cylinder 202a cannot support the smooth cylinder 302a. Therefore, a sliding ring 302b is provided on the smooth cylinder 302a, which is engaged with a preset annular groove 202b on the inner side surface of the cylinder 202a, so that the smooth cylinder 302a can rotate in the cylinder 202a and can also be kept from falling in the cylinder 202a.

[0034] In addition, a turntable 303b is connected to the smooth cylinder 302a through a rotating cylinder 303a, making it more convenient to rotate the smooth cylinder 302a and facilitating operation.

[0035] The engaging groove portion 202 further includes limiting grooves 202c arranged in an annular array on the inner side surface of the annular groove 202b; the smooth column portion 302 further includes limiting blocks 302c for engaging the limiting grooves 202c, a cavity 302d provided in the smooth cylinder 302a, the rotating cylinder 303a and the rotating disc 303b, a sliding hole 302e provided between the outer ring surface of the sliding ring 302b and the cavity 302d for installing the limiting blocks 302c, and a tension spring 302f provided on the limiting blocks 302c and connected to the inner side surface of the cavity 302d.

[0036] In this embodiment, the limiting blocks 302c can be engaged in the limiting grooves 202c, so that the sliding ring 302b stops rotating, thereby making the threaded column 301 stop rotating, and finally fixing the suspension rod 101 at a certain height.

[0037] In addition, due to the provision of the tension spring 302f and the contact portion between the end of the limiting block 302c and the limiting groove 202c being an arc structure, by rotating the rotating disc 303b, the limiting block 302c jacks up the tension spring 302f and disengages from the limiting groove 202c, releasing the engagement state of the sliding ring 302b and enabling the threaded column 301 to rotate again.

[0038] The smooth column portion 302 further includes a pulling ring 302g provided on the limiting block 302c and connected to the tension spring 302f, and a fixing ring 302h provided on the inner wall of the cavity 302d and sleeving the limiting block 302c; the rotating disc portion 303 further includes a pulling rope 303c provided on the limiting block 302c.

[0039] In this embodiment, although the limiting block 302c can be disengaged from the limiting groove body 202c by slightly applying an external force under the action of the tension spring 302f, there is still a risk of jamming in this way. Therefore, the pulling rope 303c is provided to play a pulling role behind the limiting block 302c. When it is necessary for the limiting block 302c to be disengaged from the limiting groove body 202c, it can be achieved by pulling the pulling rope 303c.

[0040] In addition, when the pulling rope 303c is released, the limiting block 302c can return to the limiting groove body 202c under the action of the tension spring 302f. The pulling ring 302g and the fixed ring 302h are provided so that the tension spring 302f can be better fixed to the limiting block 302c, making the pulling force of the tension spring 302f on the limiting block 302c more uniform.

[0041] The rotating disk portion 303 further includes a push column hole body 303e provided on the rotating disk 303b and communicating with the cavity 302d, a push column 303f provided in the push column hole body 303e, a pulling plate 303g provided on the bottom surface of the push column 303f and connected to the pulling rope 303c, a mounting hole body 303h provided on the pulling plate 303g, a fixing rod 303j provided on the inner side surface of the cavity 302d and passing through the mounting hole body 303h, and a spring 303k provided between the two fixing rods 303j and jacking up the pulling plate 303g.

[0042] In this embodiment, it is not convenient to operate the rotating disk 303b while pulling the pulling rope 303c. Therefore, the push column 303f is provided to achieve the technical effect of pulling the pulling rope 303c. In this way, it is also convenient to control the rotating disk 303b at the same time. When in use, press down the push column 303f to drive the pulling rope 303c to move downward. By changing the direction of the pulling rope 303c, it becomes a rightward pull on the limiting block 302c.

[0043] In addition, the pulling plate 303g is provided so that the force application direction for pulling the pulling rope 303c is consistent with the extending direction of the pulling rope 303c, and the moving direction of the pulling plate 303g is fixed by the fixing rod 303j. At the same time, an additional spring 303k is provided to jack up the push column 303f to reset it.

[0044] The smooth column part 302 further includes an upper fixed pulley 303m disposed on the inner side surface of the cavity 302d and used for straightening and tensioning the pulling rope 303c, and a lower fixed pulley 303n disposed on the inner side surface of the cavity 302d and used for straightening and tensioning the lower end of the pulling rope 303c.

[0045] In this embodiment, the upper fixed pulley 303m is disposed at the tail of the limiting block 302c, and the lower fixed pulley 303n is disposed above the pulling plate 303g. The cooperation of the upper fixed pulley 303m and the lower fixed pulley 303n enables the pulling rope 303c to be perpendicular to the contact surface when connected to the limiting block 302c and the pulling plate 303g. In this way, there is no component force in the left and right directions during the pulling process of the pulling rope 303c, thereby reducing the wear phenomenon between the limiting block 302c and the pulling plate 303g.

[0046] The smooth column part 302 further includes a middle fixed pulley 303p disposed on the inner side surface of the cavity 302d and used for straightening and tensioning the middle section of the pulling rope 303c.

[0047] In this embodiment, the middle fixed pulley 303p is disposed below the upper fixed pulley 303m and is horizontally tangent to the lower fixed pulley 303n. The middle fixed pulley 303p tensions the pulling rope 303c inside the cavity 302d to prevent it from contacting the inner side surface of the cavity 302d, thus avoiding wear during the movement process.

[0048] The chute unit 2 further includes a support ring 203 disposed on the inner side surface of the C-shaped groove body 201; the stud unit 3 further includes a snap ring 304 disposed on the threaded stud 301 and located above the support ring 203.

[0049] In this embodiment, the support ring 203 supports the snap ring 304 upward, and cooperates with the snap groove portion 202 and the smooth column part 302 to jointly fix the threaded stud 301.

[0050] The frame unit 1 further includes a load-bearing spring 104 disposed on the hanging rod 101 and connected to the ceiling B, and a load-bearing rod 103 disposed between the hanging rod 101 and the suspended ceiling A.

[0051] In this embodiment, it is difficult to support the suspended ceiling A only by the threaded stud 301. Therefore, a plurality of the load-bearing springs 104 are disposed on the hanging rod 101 and connected to the ceiling B to reduce the force on the threaded stud 301, and the load-bearing rod 103 is disposed to facilitate the connection between the hanging rod 101 and the suspended ceiling A.

[0052] The above has made a detailed description of the embodiments of the present invention. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various modifications can be made without departing from the gist of the present invention. These are all non-creative modifications and are protected by the patent law as long as they are within the scope of the claims of the present invention.
