[0037] Please refer to Figures 1-5 , the embodiment of the present application provides a bracket anti-falling structure, including: a bracket main body 10, a folding frame 20, and at least one anti-falling mechanism 30; the folding frame 20 is slidably connected to the bracket main body 10. During the process of the folding frame 20 extending and folding, its end slides relative to the bracket main body 10 to realize the rising and falling of the bracket main body 10. The anti-falling mechanism 30 is fixedly arranged on the bracket main body 10. The anti-falling mechanism 30 is provided with a transmission component 31 and a braking component 32. When the bracket main body 10 falls rapidly, the folding frame 20 slides relative to the bracket main body 10 at an accelerated speed. Through the transmission of the transmission component 31, the braking component 32 is triggered to generate resistance to brake the folding frame 20 and the bracket main body 10, thereby preventing the bracket main body 10 from continuing to fall.

[0038] Specifically, the braking assembly 32 is provided with a fixing member 322 fixedly connected to the bracket main body 10, and a braking member 321 that can abut against the fixing member 322 to generate resistance. The folding frame 20 is connected to the driving end of the transmission assembly 31, and the braking member 321 is movably connected to the driving end of the transmission assembly 31. The folding frame 20 slides to drive the transmission assembly 31 to work, thereby driving the braking member 321 to abut against the fixing member 322 to generate resistance, so as to brake the folding frame 20 and the bracket main body 10 to prevent the bracket main body 10 from falling.

[0039] For the anti-falling structure of the bracket provided in the embodiment of the present application, by fixedly arranging the anti-falling mechanism 30 on the bracket main body 10, when the bracket main body 10 rapidly drops, the folding frame 20 rapidly slides relative to the bracket main body 10 to trigger the braking member 321 to abut against the fixing member 322 to generate resistance, so as to brake the folding frame 20 and the bracket main body 10 to prevent the bracket main body 10 from falling and improve the safety performance. Compared with the conventional setting method of arranging the anti-falling mechanism 30 on the folding frame 20 through a rotating shaft and the folding frame 20 driving the anti-falling mechanism 30 to move relative to the bracket main body 10 together, the embodiment of the present application can avoid the folding frame 20 getting stuck during movement caused by the rotation axis deflection that may be caused by the movement of the anti-falling mechanism 30 during the normal extension and folding of the folding frame 20, thereby ensuring the smoothness of the normal ascending and descending of the bracket main body 10 and improving the stability of the folding frame 20 and the bracket main body 10.

[0040] Please refer to Figures 2-5 Furthermore, in some embodiments, the braking assembly 32 further includes a limiting member 323. One end of the limiting member 323 is connected to the driving end of the transmission assembly 31, and the other end is connected to the braking member 321. When the bracket main body 10 is normally ascending and descending, the limiting member 323 provides resistance so that the braking member 321 moves synchronously and uniformly with the driving end of the transmission assembly 31; when the bracket main body 10 rapidly falls, the braking member 321 accelerates to overcome the resistance of the limiting member 323, and then abuts against the fixing member 322 to brake the bracket main body 10. Specifically, the limiting member 323 can be a structure such as a shrapnel or a spring that can elastically deform to generate elastic force, and is not limited thereto.

[0041] Furthermore, in some embodiments, the transmission assembly 31 includes a transmission member 311 and a driven member 312. The transmission member 311 is connected to the folding frame 20 and is driven by the folding frame 20 to slide relative to the bracket main body 10. One end of the driven member 312 is connected to the transmission member 311, and the other end is slidably connected or eccentrically connected to the braking member 321, so that the braking member 321 can accelerate to abut against the fixing member 322 to brake.

[0042] Further, in some embodiments, the transmission member 311 is provided with a rack 3111 slidably connected to the bracket main body 10. The folding frame 20 is hinged to the rack 3111. The driven member 312 is provided with a driven gear 3121 and a pin shaft 313. The driven gear 3121 is sleeved on the pin shaft 313. One end thereof is in transmission connection with the rack 3111; the other end is connected to the braking member 321. In this setting mode, one end of the limiting member 323 is fixedly connected to the end of the driven gear 3121 away from the rack 3111, and the other end is fixedly connected to the braking member 321, and is used to provide resistance to ensure that the driven gear 3121 drives the braking member 321 to rotate at a uniform speed when the bracket main body 10 is lifting and lowering normally.

[0043] Further, in some embodiments, the driven member 312 is further provided with a turntable 314, and the turntable 314 is arranged inside the fixing member 322. The turntable 314 and the driven gear 3121 are respectively pivotally connected to both ends of the pin shaft 313, and the turntable 314 and the driven gear 3121 are synchronously rotated through the pin shaft 313, and the braking member 321 is movably connected to the turntable 314. In this setting mode, when the bracket main body 10 is lifting and lowering normally, the folding frame 20 drives the rack 3111 to slide along the length direction of the bracket main body 10, and drives the pin shaft 313 to rotate through the driven gear 3121 engaged with the rack 3111, and then drives the turntable 314 and the braking member 321 to rotate together. In some other embodiments, the turntable 314 and the driven gear 3121 are coaxially arranged and fixedly connected to the driven gear 3121. In this setting mode, when the bracket main body 10 is lifting and lowering normally, the driven gear 3121 directly drives the turntable 314 and the braking member 321 to rotate synchronously and at a uniform speed. This transmission structure is simple, and the transmission process is stable and easy to implement.

[0044] It should be noted that the above-mentioned transmission structure is only several preferred setting modes of the transmission assembly 31. In some other embodiments, the driven member 312 may also be a worm and gear structure or other transmission structures, which will not be elaborated here.

[0045] Please refer to Figure 3 and Figure 4 , further, in some embodiments, the turntable 314 is provided with a limiting notch 3141 along the edge. The braking member 321 is arranged at the limiting notch 3141, and one end thereof is rotatably connected to the turntable 314 on one side of the limiting notch 3141 through a rotating shaft. The limiting member 323 abuts against the other end of the braking member 321 to give the braking member 321 a resistance to rotate around the rotating shaft. When the bracket main body 10 is lifting and lowering normally, the braking member 321 and the turntable 314 rotate synchronously and at a uniform speed. When the bracket main body 10 falls rapidly, the braking member 321 rotates around the rotating shaft. After its centrifugal force overcomes the resistance of the limiting member 323, a part protrudes from the edge of the turntable 314 and abuts against the fixing member 322 in the circumferential direction, and the driven member 312 is braked through the braking member 321 to realize the braking of the bracket main body 10.

[0046] In some other embodiments, the turntable is provided with a chute, one end of the braking member is slidably connected to the chute, one end of the limiting member is connected to the turntable, and the other end is connected to the braking member. When the bracket body rapidly drops, the braking member slides away from the axis along the chute against the resistance of the limiting member until it abuts against the fixing member.

[0047] Further, in some embodiments, the inner wall surface of the fixing member 322 is provided with internal ratchet teeth, the braking member 321 is disposed inside the fixing member 322, and external ratchet teeth capable of abutting against the internal ratchet teeth are provided on its edge.

[0048] Please refer to FIGS. 2 and Figure 5 , further, in some embodiments, the bracket body 10 is provided with a slider 13, the slider 13 can slide along the length direction of the bracket body 10, the folding frame 20 is hinged to the slider 13, and the rack 3111 is fixedly connected to the slider 13 parallel to the sliding direction of the slider 13. Preferably, the rack 3111 is integrally formed with the slider 13.

[0049] Further, the anti-falling mechanism 30 is disposed inside or outside the bracket body 10. As an example, the anti-falling structure of the bracket is disposed outside the bracket body 10 to simplify the internal structure of the bracket body 10, thereby avoiding affecting the folding and unfolding of the folding frame 20.

[0050] Specifically, a slide rail 11 is provided inside the bracket body 10, the slider 13 is slidably disposed in the slide rail 11, a strip-shaped hole 12 is opened along the length direction on the side surface or the bottom of the bracket body 10, and the rack 3111 passes through the strip-shaped hole 12 and protrudes from the bracket body 10. The driven gear 3121 is pivotally connected to the pin shaft 313 and is rotatably disposed outside the bracket body 10. The driven gear 3121 is driven to rotate by the rack 3111 sliding along the strip-shaped hole 12, and then the turntable 314 and the braking member 321 are driven to rotate. It can be understood that the anti-falling structure of the bracket can also be disposed inside the bracket body 10, which will not be elaborated here.

[0051] Preferably, the strip-shaped hole 12 is opened at the bottom of the bracket body 10, the driven gear 3121 is horizontally disposed below the bracket body 10, and the rack 3111 passes through the strip-shaped hole 12 and is in transmission connection with the driven gear 3121. The pin shaft 313 is disposed in the vertical direction. The rack 3111 drives the driven gear 3121 to rotate, and then drives the braking member 321 located at the other end of the pin shaft 313 to rotate in a horizontal plane perpendicular to the pin shaft 313. When the rack 3111 accelerates and slides, the braking member 321 deflects centrifugally in a horizontal plane perpendicular to the pin shaft 313. In this setting manner, the centrifugal deflection plane of the braking member 321 is perpendicular to the folding and unfolding plane of the folding frame 20. This can avoid the influence of gravity on the deflection of the braking member 321 and make the anti-falling mechanism 30 of the bracket more stable.

[0052] Furthermore, in some embodiments, the anti-falling mechanism 30 is further provided with an installation box 33 for supporting the anti-falling mechanism 30 and fixing the anti-falling mechanism 30 to the bracket main body 10. Preferably, the installation box 33 covers the outside of the strip-shaped hole 12, and the pin shaft 313 passes through the bottom of the installation box 33 and is arranged perpendicular to the plane where the strip-shaped hole 12 is located. The driven gear 3121 and the turntable 314 are arranged at both ends of the pin shaft 313 and are located inside and outside the installation box 33 respectively. The fixing member 322 is fixed to the bottom of the installation box 33 and covers the outside of the turntable 314. In this way, the anti-falling mechanism 30 is separated into two independent spaces, that is, the transmission structure formed by the combination of the rack 3111 and the transmission gear is arranged in the first space formed by the enclosure of the installation box 33 and the bracket main body 10, so as to ensure that the transmission of the rack 3111 and the transmission gear is not interfered by the external environment; the braking structure formed by the combination of the braking member 321 and the fixing member 322 is arranged in the second space formed by the enclosure of the fixing member 322 and the installation box 33, so as to ensure that the braking stroke of the braking member 321 and the fixing member 322 is not interfered by the external environment, thereby reducing the interference degree between irrelevant components and improving the stability of the anti-falling mechanism 30.

[0053] Please refer to Figure 1 , this embodiment of the present application further provides a clothes dryer, which is provided with the above-mentioned bracket anti-falling structure, and the bracket main body 10 is driven to rise or fall by a traction rope. When the traction rope suddenly breaks, the bracket main body 10 quickly falls to trigger the braking of the anti-falling mechanism 30, so as to avoid the quick fall of the bracket main body 10 and improve the overall safety performance and stability performance of the clothes dryer.

[0054] Compared with the prior art, the beneficial effects of a bracket anti-falling structure provided by this embodiment of the present application are as follows:

[0055] (1) It is provided with a bracket anti-falling structure, and the bracket anti-falling structure is triggered to work by the folding frame sliding relative to the bracket main body at an accelerated speed to realize the braking of the bracket main body, so as to avoid the quick fall of the bracket main body and improve the overall safety performance and stability performance of the clothes dryer;

[0058] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and the present utility model also intends to include these modifications and variations.
