DETAILED DESCRIPTION
[0040] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.
[0041] In the description of this application, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.
[0043] With the continuous improvement of the quality of life, clothes drying machines are increasingly gaining favor and recognition among consumers. However, with the continuous advancement of clothes drying machine technology, its safety issues are becoming increasingly important. Most clothes drying machines currently on the market use an electric drive system to pull the wire rope, which is connected to the bracket, and the bracket carries the clothes drying rod. In this structure, the wire rope plays a key load-bearing role. However, it is worth noting that once the wire rope breaks accidentally, it will directly cause the bracket and the clothes drying rod on it to fall off, which may cause serious personal injury accidents. Therefore, existing clothes drying machines have the safety hazard that when the wire rope breaks accidentally, the clothes drying rod will fall freely and injure the user.
[0044] In order to overcome the above technical problems, the embodiment of the present application provides an anti-falling mechanism for a clothes drying machine, which can be applied to the clothes drying machine. The clothes drying machine includes a clothes drying main unit, a traction device, a telescopic bracket 1 and a drying rack. The clothes drying main unit can be hoisted under the ceiling, and the traction device is installed in the clothes drying main unit. The traction device extends a steel wire rope 6 that hangs down and connects to the drying rack. The telescopic bracket 1 is connected between the clothes drying main unit and the drying rack. When working, the drying rack can be used to hang clothes. The drying rack is driven to rise and fall by the winch of the traction device. The telescopic bracket 1 can maintain the stability of the drying rack and avoid the problem of the drying rack shaking and swinging during the lifting process. Under normal circumstances, the steel wire rope 6 is the main load-bearing object of the drying rack, and the telescopic bracket 1 does not bear any weight. When the steel wire rope 6 accidentally breaks, the drying rack will fall freely and rapidly under the action of its own gravity, and the falling process will drive the telescopic bracket 1 to extend rapidly. Based on the anti-fall mechanism of this solution, when the wire rope 6 breaks accidentally, the anti-fall mechanism can quickly and automatically lock the telescopic bracket 1, so that the telescopic bracket 1 cannot be extended. Under the restriction of the telescopic bracket 1, the drying rack cannot fall, thereby avoiding the problem of accidental falling of the drying rack.
[0045] In order to achieve the anti-fall function, combined with Figure 1-7 The anti-fall mechanism of this embodiment includes at least a first locking and mating unit 3, a second locking and mating unit 4, and a micro switch 5; the first locking and mating unit 3 is connected to the telescopic bracket 1; the second locking and mating unit 4 is transmission-connected to the wire rope 6; the micro switch 5 includes an elastic member 52, which is transmission-connected to the second locking and mating unit 4;
[0046] In which, the second locking mating unit 4 has a locked state and an unlocked state. When the steel wire rope 6 is in the tensioned state, the second locking mating unit 4 is in the unlocked state, and the telescopic bracket 1 can be freely extended and retracted; when the steel wire rope 6 is in the relaxed state, the elastic member 52 drives the second locking mating unit 4 to switch to the locked state in cooperation with the first locking mating unit 3, and at this time the extension freedom of the telescopic bracket 1 is locked.
[0047] It can be understood that under normal conditions, one end of the steel wire rope 6 is connected to the traction device and the other end is connected to the drying rack. Under the action of the gravity of the drying rack, the steel wire rope 6 will always be in a tensioned state. When the steel wire rope 6 breaks, due to the lack of traction of the drying rack, the steel wire rope 6 will instantly become relaxed. Therefore, the tensioned steel wire rope 6 indicates that its function is normal, while the relaxed steel wire rope 6 indicates that it may break. The second locking mating unit 4 of this scheme is transmission-connected with the wire rope 6 and the elastic member 52, and its locking and unlocking states are controlled by the tightness of the wire rope 6. When the wire rope 6 is tensioned, the second locking mating unit 4 is in the unlocked state, and the elastic member 52 is compressed to store elastic potential energy; when the wire rope 6 is relaxed, the wire rope 6 cannot give the second locking mating unit 4 enough force, and the elastic member 52 releases the elastic potential energy to drive the second locking mating unit 4 to jump to the locked state. In this way, this embodiment uses the wire rope 6 and the elastic member 52 to control the second locking mating unit 4, which can just meet the control requirements that the second locking mating unit 4 remains unlocked when the wire rope 6 is normal, and the second locking mating unit 4 is automatically locked when the wire rope 6 breaks.
[0048] Furthermore, the inventors discovered during their experiments that, in actual use, wire rope 6 slack is not caused only by a break in the clothes drying rack. During the descent process, if the rack encounters an obstruction below and cannot continue to descend, the unfurled wire rope 6 can also slack. Furthermore, wire rope 6 generally only breaks in extreme circumstances, and this is more likely to occur when the rack encounters an obstruction during descent. Normally, when the rack encounters an obstruction during descent, wire rope 6 needs to be reversed and reeled in to raise the rack to prevent it from losing balance. In this embodiment, first, in the locked state, the extension freedom of the telescopic bracket 1 is locked, but its retraction freedom is not. That is, if wire rope 6 breaks or if the rack encounters an obstruction during descent, the extension freedom of the telescopic bracket 1 is locked, thus limiting the rack's descent. Importantly, the retraction freedom of the telescopic bracket 1 is not locked. If an obstruction is detected during descent, the wire rope 6 is reversed and the rack is lifted. Furthermore, the telescopic bracket 1 can be squeezed and retracted normally during the rise of the rack. Secondly, the micro switch 5 provided in this scheme can indirectly sense the tightness of the wire rope 6 through the second locking matching unit 4. For example, when the wire rope 6 is normally suspending the drying rack, the wire rope 6 is tensioned, and the transmission component 42 controls the micro switch 5 to remain in the triggered or disconnected state; when the wire rope 6 is loose (it may be that the drying rack encounters resistance when descending), the transmission component 42 switches the position state, and the micro switch 5 switches to the disconnected or triggered state, thus realizing the function of automatically detecting resistance of the drying rack; wherein, the micro switch 5 is connected to the control system signal of the clothes drying machine, and the control system can be automatically controlled according to the signal of the micro switch 5. When resistance is detected, it can automatically reverse the operation to raise the drying rack to maintain the problem of the drying rack, that is, the function of automatic lifting when resistance is encountered is realized.
[0049] In summary, the anti-fall mechanism of the clothes drying machine based on this embodiment includes a first locking cooperation unit 3 and a second locking cooperation unit 4 that can cooperate with each other to lock. The first locking cooperation is connected to the telescopic bracket 1, and the second locking cooperation unit 4 is connected to the wire rope 6. Under normal circumstances, the wire rope 6 is always in a tensioned state. Under the action of the wire rope 6, the second locking cooperation unit 4 is in an unlocked state, and the telescopic bracket 1 can be freely extended and retracted without affecting the lifting function of the clothes drying rack; when an accident occurs in which the wire rope 6 breaks, the wire rope 6 is in a relaxed state after breaking. At this time, the elastic part 52 of the micro switch 5 can push the second locking cooperation unit 4 to jump to the locked state to lock the first cooperation locking part. After the first cooperation locking part is locked, the extension freedom of the telescopic bracket 1 is locked. Since the telescopic bracket 1 cannot continue to extend, the clothes drying rack connected below cannot continue to descend, thereby avoiding the problem of the clothes drying rack falling freely after losing the traction of the wire rope 6 and causing accidents.
[0050] In addition, since the wire rope 6 will also become loose when the drying rack encounters resistance during its descent process, the micro switch 5 can also transmit the signal of the loose wire rope 6 to the control system of the clothes drying machine. Therefore, when the system learns that the wire rope 6 is loose and the drying rack may encounter resistance, it can control the reverse winding of the wire rope 6 to lift the drying rack to maintain the stability of the drying rack.
[0051] In summary, this solution, through a simple structure, not only realizes the function of preventing the drying rack from accidentally falling, but also realizes the function of automatically lifting the drying rack when encountering obstacles. It has the advantages of simple structure, low cost, high safety and rich functions.
[0052] In some embodiments, referring to Figure 2 The second locking fitting unit 4 includes a locking fitting 41 and a transmission assembly 42; the locking fitting 41 is used to cooperate with the first locking fitting unit 3 to form a lock, and it is installed on the transmission assembly 42; the transmission assembly 42 transmits and connects the steel wire rope 6 and the elastic member 52.
[0053] Specifically, when the wire rope 6 is tensioned, the transmission assembly 42 is stable, and the locking member 41 is spaced away from the first locking member 3 to maintain the unlocked state. At this time, the elastic member 52 is squeezed by the transmission assembly 42 to maintain the stored elastic potential energy. When the wire rope 6 slackens, the transmission assembly 42 can quickly respond and drive the locking member 41 toward the first locking member 3, achieving rapid locking and effectively preventing the drying rack from falling. The design of the fit between the locking member 41 and the first locking member 3 ensures sufficient strength and stability in the locked state, preventing accidental unlocking. Furthermore, this design can adapt to clothes drying racks of different specifications and types, as the transmission frame 421 and the locking member 41 can be adjusted and optimized as needed.
[0054] In some embodiments, referring to Figure 4 The locking fitting 41 is a ratchet bar extending along the movable direction of the first locking fitting unit 3, and a plurality of ratchet grooves 411 are spaced apart on the ratchet bar. The first locking fitting unit 3 is provided with a latching tooth 311 for cooperating with the ratchet groove 411; in the locked state, the latching tooth 311 is inserted into the ratchet groove 411, and the ratchet groove 411 locks the latching tooth 311 in one direction.
[0055] The first locking mating unit 3 is installed on the telescopic bracket 1, so the first locking mating unit 3 will be driven to move during the extension and retraction of the telescopic bracket 1 (it may be up and down movement, or it may be left and right movement, which is determined by the specific installation position of the first locking mating unit 3 on the telescopic bracket 1). The ratchet bar is a form of locking mating part 41, which extends along the movement direction of the first locking mating unit 3, which means that the length direction of the ratchet bar is consistent with the movement direction of the first locking mating unit 3. There are multiple ratchet grooves 411 spaced apart on the ratchet bar, and these ratchet grooves 411 are specially designed to cooperate with the latch teeth 311 on the first locking mating unit 3 to achieve the locking function. The first locking mating unit 3 is provided with latch teeth 311, which are used to cooperate with the ratchet grooves 411 on the ratchet bar. The shape and size of the latch teeth 311 usually match the ratchet grooves 411 to ensure that they can fit tightly together. In the locked state, the latch tooth 311 of the first locking mating unit 3 will be locked into the ratchet groove 411 on the ratchet bar. The ratchet groove 411 realizes a one-way locking of the latch tooth 311. After locking, the first locking mating unit 3 cannot be driven to move by the extended telescopic bracket 1, thereby limiting the extension of the telescopic bracket 1; however, the locked first locking mating unit 3 can be driven to move by the retracted telescopic bracket 1, so the telescopic bracket 1 can retract normally.
[0056] In some embodiments, the first locking and fitting unit 3 includes a ratchet 31 rotatably connected to the telescopic bracket 1 , and the latch teeth 311 are disposed on a periphery of the ratchet 31 .
[0057] The first locking mating unit 3 is provided with a ratchet 31, so that, in the locked state, the steel wire rope 6 drives the drying rack to rise, and during the process of the telescopic bracket 1 being squeezed and contracted, the ratchet 31 can roll along the ratchet bar to separate the latch teeth 311 from the ratchet groove 411, thereby avoiding the problem of the latch teeth 311 jumping relative to the ratchet bar, and improving the smoothness and stability of the contraction process of the telescopic bracket 1.
[0058] In some embodiments, referring to Figure 6The transmission component 42 can be installed in a liftable manner in the clothes drying main unit. The transmission component 42 includes a connected transmission shaft 423 and a transmission frame 421. The locking fitting 41 is installed on the transmission frame 421. The transmission shaft 423 is connected to the steel wire rope 6 and the elastic member 52. The transmission shaft 423 can be pressed down by the tensioned steel wire rope 6 to make the locking fitting 41 move away from the first locking fitting unit 3; and the transmission shaft 423 can be lifted up by the elastic member 52 to make the locking fitting 41 close to the first locking fitting unit 3 for mating and locking.
[0059] The transmission frame 421 can provide a stable and reliable installation space for the locking fitting 41. The transmission shaft 423 can cooperate with the wire rope 6 and the elastic part 52 to transmit the force of the wire rope 6 and the elastic part 52 to the transmission frame 421, thereby transmitting the force of the wire rope 6 and the elastic part 52 to the locking fitting 41, thereby achieving the purpose of using the wire rope 6 to transmit and control the locking fitting 41.
[0060] In specific applications, the transmission assembly 42 is appropriately installed according to the installation position of the anti-fall mechanism of this embodiment. It can be installed in the clothes drying main unit or on the clothes drying rack.
[0061] In some embodiments, the transmission assembly 42 further includes a pulley 424 rotatably mounted on the transmission shaft 423 , the wire rope 6 passes around the pulley 424 , and the tensioned wire rope 6 presses down the transmission shaft 423 through the pulley 424 .
[0062] Since the wire rope 6 needs to be frequently hoisted during operation, if the wire rope 6 is directly brought into contact with the drive shaft 423 to apply pressure, the sliding friction between the wire rope 6 and the drive shaft 423 will cause the wire rope 6 to wear quickly and easily generate noise; after a rotatable pulley 424 is provided, the pulley 424 is used as a transmission medium, thereby achieving the purpose of indirectly controlling the drive shaft 423 by the wire rope 6, and during operation, the wire rope 6 and the pulley 424 are in rolling friction, thereby effectively reducing the wear speed of the wire rope 6 and avoiding the problem of wear noise.
[0063] In specific application, the clothes drying host includes a main body case, the main body case includes a case frame, the case frame includes two left and right side panels and two front and rear case fixing parts 2, optionally, each case fixing part 2 is respectively installed with a transmission component 42, specifically, the axle is installed in a liftable manner on the case fixing part 2; the traction device provided in the clothes drying host extends two steel ropes 6 from the front and back respectively, and the two steel ropes 6 respectively pass around the two front and rear pulleys 424 and then hang down and connect to the drying rack. Therefore, in this structure, the transmission component 42 can not only control the tightness of the steel rope 6 to transmit the locking fitting 41, but also be used to provide support and steering for the steel rope 6, so that the steel rope 6 can be connected to the front and rear ends of the drying rack respectively, thereby providing a stable pulling force for the drying rack.
[0064] In some embodiments, referring to Figure 5 The transmission assembly 42 also includes two support plates 425 located on both sides of the rope pulley 424. The support plates 425 are fixed in the clothes drying machine. A long hole 4251 is provided on the support plate 425. The transmission shaft 423 passes through the long hole 4251 and the rope pulley 424. The transmission shaft 423 and the rope pulley 424 can slide up and down along the long hole 4251.
[0065] Specifically, the transmission shaft 423 passes through the elongated hole 4251 and supports the rope pulley 424 located between the two support plates 425, thereby enabling the rope pulley 424 to be rotatably installed. A flat portion is provided on the transmission shaft 423 to limit the rotation of the transmission shaft 423; the transmission shaft 423 can slide up and down along the elongated hole 4251. Then, when the wire rope 6 is tensioned, under the action of the gravity of the drying rack, the rope pulley 424 and the transmission shaft 423 are pressed downward, driving the locking fitting 41 downward away from the first locking fitting unit 3 above, at which time the telescopic bracket 1 can normally extend and retract; when the wire rope 6 is relaxed, the elastic member 52 pushes the transmission shaft 423 upward along the elongated hole 4251, driving the locking fitting 41 upward toward the first locking fitting 41, and cooperating with the locking fitting 41 to lock the extension of the telescopic bracket 1. This structure can achieve stable and reliable installation of the transmission assembly 42, while also providing reliable support and steering for the wire rope 6.
[0066] Optionally, the support plate 425 and the box fixing member 2 are an integral structure.
[0067] In some embodiments, the micro switch 5 is fixed in the clothes drying machine and is located between the rope pulley 424 and the transmission frame 421 .
[0068] The micro switch 5 is arranged between the rope pulley 424 and the transmission frame 421, and can lift the transmission shaft 423 from the middle. This position can provide a better balanced thrust to achieve stable lifting of the second locking matching unit 4.
[0069] In some embodiments, referring to Figure 6 The transmission assembly 42 also includes a guide member 422 fixed in the clothes drying machine, and the transmission frame 421 is slidably connected to the guide member 422, and the guide member 422 guides the lifting of the transmission frame 421.
[0070] The main function of the guide member 422 is to provide a stable path or direction to guide the transmission assembly 42 to move in a predetermined manner, ensure that the locking fitting 41 on the transmission frame 421 can be stably locked with the first locking fitting unit 3, and ensure the stability of the locking fitting 41.
[0071] In some embodiments, referring to Figure 1-2 The telescopic bracket 1 includes a bracket body 11 and a bracket guide rail. A sliding connection part 111 is respectively provided at the upper and lower ends of the bracket body 11. The sliding connection part 111 is slidably connected to the bracket guide rail, and the horizontal sliding of the sliding connection part 111 is guided by the bracket guide rail; the first locking matching unit 3 is connected to the sliding connection part 111. In the locked state, the second locking matching unit 4 locks the horizontal sliding of the first locking matching unit 3 to lock the extension freedom of the telescopic bracket 1.
[0072] Specifically, the bracket body 11 is a scissors bracket, and its upper and lower ends are respectively slidably connected to the bracket guide rails through sliding connection parts 111. During the upward and downward extension of the bracket body 11, the sliding connection part 111 will slide horizontally along the bracket guide rail. Therefore, by locking the horizontal sliding freedom of the sliding connection part 111, the extension and retraction of the bracket body 11 can be locked.
