Description

Technical Field

[0001] This utility model relates to the field of home furnishing products, specifically to a lifting mechanism for a clothes drying machine and a clothes drying machine. Background Technology

[0002] In existing technology, the main body of the drying machine uses a motor to wind or unwind the rope to pull the drying items connected by the rope to rise or fall. At the same time, a telescopic frame is used to support the strength of the drying rack. The telescopic frame does not have a corresponding power component installed. It extends and retracts with the rise and fall of the drying items. When the rope breaks due to its service life or other reasons, it falls under the weight of the drying items. The telescopic frame extends to its maximum distance. At this time, the distance between the drying items and the main body of the drying machine is the largest, which can easily cause damage to objects or danger to people. Utility Model Content

The two rotating ends or the two sliding ends are adapted to make the distance between the first object and the second object less than the maximum extension distance of the telescopic frame when they abut against the limiting part.

[0019] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0020] 1. In Scheme 1 and its preferred embodiments, a lifting mechanism for a clothes drying machine is used to be installed on a first object, the first object being the clothes drying machine body or a ceiling, including drying components and a telescopic frame.

[0021] The drying rack is used for drying clothes and other objects. It is suitable for connecting to the drying machine body via a rope and for being driven by the drying machine body to move up and down in the vertical direction. When the drying rack is lowered, it is convenient for users to place items, and when it is raised, it is convenient for drying.

[0022] The telescopic rack includes at least two rotating ends and at least two sliding ends, the rotating ends being rotatably connected to one of the first object and the drying item, and the sliding ends being slidably connected to the other.

[0023] The drying rack is equipped with a limiting part. As the distance between the first object and the drying rack gradually increases, the two rotating ends or two sliding ends gradually approach the limiting part. That is, the limiting part is located on the sliding extension path of the telescopic frame, and the two rotating ends or two sliding ends are adapted to ensure that the distance between the first object and the drying rack is less than the maximum extension distance of the telescopic frame when they abut against the limiting part. This prevents the telescopic frame from extending to its maximum distance due to the weight of the drying rack when the rope breaks, thus avoiding damage to the object or danger to personnel. The two rotating ends or two sliding ends are adapted to lock when they abut against the limiting part, that is, interlocking is achieved through two limiting points, with only one side locked, ensuring that the drying rack will not tilt further when the limiting part is engaged.

[0024] 2. In Scheme 2 and its preferred embodiments, the drying component is provided with a sliding groove, the opening of the sliding groove faces the first object, the sliding end is adapted to slide in the sliding groove, and the drying component is also provided with a limiting part protruding from the groove wall of the sliding groove. The limiting part is located in the sliding groove to achieve concealment, which is more aesthetically pleasing.

[0025] 3. In Scheme 3 and its preferred embodiments, the drying component includes a second frame and two second limiting members. The second frame is provided with a sliding groove, and the second limiting members are connected to the second frame and have limiting parts suitable for extending into the sliding groove. The separate manufacturing facilitates installation and allows the sliding end to be installed in the sliding groove before the second limiting members are installed. Thus, the sliding end will not interfere with the second limiting members during the installation process, which facilitates the installation of the sliding end.

[0026] 4. In Scheme 4 and its preferred embodiments, the second frame is provided with a threaded hole communicating with the sliding groove, and the second limiting member is a fastener that is threadedly connected to the threaded hole. The structure is simple, easy to process, and low in cost.

[0027] 5. In Scheme 5 and its preferred embodiments, the second frame is provided with a threaded hole, and the second limiting member includes a limiting block and a fastener. The fastener is adapted to be threadedly connected to the threaded hole. The fastener can pass through the limiting block and be threadedly connected to the threaded hole to fix the limiting block on the second frame, and the limiting block is provided with a limiting part. The structure is simple, easy to process, and low in cost.

[0028] 6. In Scheme 6 and its preferred embodiments, the second frame is provided with multiple threaded holes arranged along the extension direction of the sliding groove, so that the second limiting member can be connected to different positions of the second frame to change the distance between the first object and the drying piece when the telescopic frame abuts against the limiting part. It can be adjusted according to the floor height and has wider applicability.

[0029] 7. In Scheme 7 and its preferred embodiments, the second frame is provided with a through hole, which is connected to the sliding groove. The second limiting member includes a fastener and a threaded fitting. The fastener is adapted to pass through the through hole and be threadedly connected to the threaded fitting. The fastener and the threaded fitting respectively clamp the surfaces where the two ends of the through hole are located. The structure is simple, easy to process, and low in cost.

[0030] 8. In Scheme 8 and its preferred embodiments, the through hole is an elongated hole extending along the sliding direction of the sliding groove, so that the second limiting member can be connected to different positions of the second frame to change the distance between the first object and the drying piece when the telescopic frame abuts against the limiting part. It can be adjusted according to the floor height and has wider applicability.

[0031] 9. In Scheme 9 and its preferred embodiments, the sliding groove and the limiting part are integrally made, eliminating the need for installation.

[0032] 10. In Scheme 10 and its preferred embodiments, a clothes drying machine includes a first object, a second object, and a telescopic frame. One of the first object and the second object is the clothes drying machine body, and the other is a clothes drying component for drying clothes and other objects. The clothes drying machine body is adapted to drive the clothes drying component to rise and fall vertically via a rope. When the clothes drying component is lowered, it is convenient for the user to place items, and when it is raised, it is convenient for drying.

[0033] The telescopic frame includes at least two rotating ends and at least two sliding ends. The rotating ends are rotatably connected to a first object, and the sliding ends are slidably connected to a second object. When the distance between the first object and the second object changes (due to the extension and retraction of the rope), the frame is driven by the drying rack, thereby changing the length of the telescopic frame in the vertical direction without causing the drying rack to move in the horizontal direction or affecting the lifting and lowering of the drying rack.

[0034] The first or second object is equipped with a limiting part. As the distance between the first and second objects gradually increases, the two rotating ends or two sliding ends gradually approach the limiting part. That is, the limiting part is located on the sliding extension path of the telescopic frame. The telescopic frame is adapted to ensure that the distance between the first and second objects is less than the maximum extension distance of the telescopic frame when it abuts against the limiting part. This prevents the telescopic frame from extending to its maximum distance due to the weight of the clothesline when the rope breaks, thus avoiding damage to the clothesline or danger to personnel. The two rotating ends or two sliding ends are adapted to lock when they abut against the limiting part, that is, interlocking is achieved through two limiting points, with only one side locked, ensuring that the clothesline will not tilt further when it is limited.

[0049] In the claims, description and accompanying drawings of this utility model, the terms "comprising", "having", and variations thereof are used to mean "including but not limited to".

[0050] refer to Figures 1-3 A clothes drying machine includes a first object 1, a second object, and a telescopic frame 3. One of the first object 1 and the second object is the drying machine body, and the other is a drying component 2. The drying machine body is adapted to drive the drying component 2 to rise and fall vertically via a rope, i.e., the rope is controlled by a motor to raise and lower, thereby pulling the drying component 2 vertically relative to the drying machine body. In this embodiment, the first object 1 is the drying machine body, and the second object is the drying component 2. The drying component 2 is adapted to be connected to the drying machine body via a rope and is adapted to be driven by the drying machine body to rise and fall vertically. The drying component 2 and the telescopic frame 3 constitute the lifting mechanism of the drying machine.

[0051] The telescopic frame 3 includes two rotating ends 31 and two sliding ends 32. The rotating ends 31 are rotatably connected to the first object 1, and the sliding ends 32 are slidably connected to the second object. When the distance between the first object 1 and the second object changes, the frame is moved by the drying rack 2, thereby changing the vertical length of the telescopic frame 3 without causing the drying rack 2 to move horizontally or affecting its lifting and lowering. In this embodiment, the telescopic frame 3 is a multi-stage scissor mechanism. In other embodiments, the first object can be the ceiling, and the two ends of the telescopic frame 3 are connected to the ceiling and the drying rack 2, respectively.

[0052] The first object 1 or the second object is provided with a limiting part 21. In this embodiment, there are two limiting parts 21, which are spaced apart. In other embodiments, only one limiting part may be provided. As the distance between the first object 1 and the second object gradually increases, the two rotating ends 31 or the two sliding ends 32 of the telescopic frame 3 gradually approach the two limiting parts 21. The two rotating ends 31 or the two sliding ends 32 of the telescopic frame 3 are adapted to make the distance between the first object 1 and the second object less than the maximum extension distance of the telescopic frame 3 when they abut against the two limiting parts 21. This prevents the second object from falling and causing the distance between the first object 1 and the second object to reach the maximum extension distance of the telescopic frame 3, thus preventing damage or danger.

[0053] The position of the surfaces of the two limiting portions 21 that abut against the two rotating ends 31 or the two sliding ends 32 is related to the position of the two rotating ends 31 or the two sliding ends 32 relative to the two limiting portions 21. Taking the abutment of the two sliding ends 32 against the two limiting portions 21 as an example, in some embodiments, when the two sliding ends 32 slide between the two limiting portions 21 to achieve extension and retraction, if the distance between the first object 1 and the second object gradually increases, the two sliding ends 32 gradually approach the two limiting portions 21, and then the two sliding ends 32 abut against the opposite surfaces of the two limiting portions 21 to achieve stopping. In some embodiments, when the two sliding ends 32 slide outside the two limiting portions 21 to achieve extension and retraction, if the distance between the first object 1 and the second object gradually increases, the two sliding ends 32 gradually approach the two limiting portions 21, and then the two sliding ends 32 abut against the mutually opposite surfaces of the two limiting portions 21 to achieve stopping (in this embodiment, only one limiting portion 21 may be provided).

[0054] Specifically, the following example will be taken with the second object (drying piece 2) having a limiting part 21:

[0055] Preferably, the second object is provided with a sliding groove 22, the opening of the sliding groove 22 faces the first object 1, the sliding end 32 is adapted to slide in the sliding groove 22, and the second object is also provided with two limiting parts 21 protruding from the groove wall of the sliding groove 22. The greater the distance between the two limiting parts 21, the smaller the falling distance of the drying piece 2 when the rope breaks.

[0056] The following are some specific solutions to this problem:

[0057] 1. The sliding groove 22 and the limiting part 21 are integrally formed.

[0058] 2. The sliding groove 22 and the limiting part 21 are made separately. The second object includes a second frame 23 and two second limiting members 24. The second frame 23 is provided with a sliding groove 22. The second limiting members 24 are detachably connected to the second frame 23 and have a limiting part 21 suitable for extending into the sliding groove 22.

[0059] There are several types:

[0060] ①Reference Figures 1-3 The second frame 23 is provided with a threaded hole 231 communicating with the sliding groove 22. The second limiting member 24 is a fastener 242, which is threadedly connected to the threaded hole 231 to achieve a detachable connection. The threaded portion or nut portion of the second limiting member 24 can be located inside the sliding groove 22 to form a limiting part 21. In this embodiment, the threaded hole 231 penetrates the groove wall of the sliding groove 22 in the vertical direction. However, it should be understood that in other embodiments, it can penetrate the groove wall of the sliding groove 22 in the horizontal direction, such as the horizontal direction being perpendicular to the sliding direction and the vertical direction of the sliding groove 22, or along the vertical direction.

[0061] Preferably, the second frame 23 is provided with a plurality of threaded holes 231 arranged along the extension direction of the sliding groove 22, so as to allow the second limiting member 24 to select a fixed position, thereby changing the distance between the two limiting parts 21, thereby changing the distance between the first object 1 and the second object when the telescopic frame 3 abuts against the limiting part 21.

[0062] ②Reference Figures 4-6 The second frame 23 is provided with a threaded hole 231. The second limiting member 24 includes a limiting block 241 and a fastener 242. The fastener 242 is adapted to be threadedly connected to the threaded hole 231 and to fix the limiting block 241 on the second frame 23. Furthermore, the fastener 242 can pass through the limiting block and be threadedly connected to the threaded hole 231, and the limiting block 241 is provided with a limiting part 21.

[0063] Preferably, the second frame 23 is provided with a plurality of threaded holes 231 along the extension direction of the sliding groove 22, so as to allow the second limiting member 24 to select a fixed position, thereby changing the distance between the two limiting parts 21, thereby changing the distance between the first object 1 and the second object when the telescopic frame 3 abuts against the limiting part 21.

[0064] ③ The second frame 23 has a through hole that communicates with the sliding groove 22. The second limiting member 24 includes a fastener 242 and a threaded fitting. The fastener 242 is adapted to pass through the through hole and be threadedly connected to the threaded fitting. The fastener 242 and the threaded fitting respectively clamp the surfaces of the two ends of the through hole. Similarly, the direction in which the through hole passes through the groove wall of the sliding groove 22 is not restricted. The threaded fitting can be a nut.

[0065] Preferably, the through hole is an elongated hole extending along the sliding direction of the sliding groove 22, so as to allow the second limiting member 24 to select a fixed position, thereby changing the position of the limiting part 21, thereby changing the distance between the first object 1 and the second object when the telescopic frame 3 abuts against the limiting part 21.

[0066] ④ The above-mentioned threaded connection is used to achieve the detachable connection of the second frame 23 and the second limiting member 24. In other embodiments, it can also be an interference fit, snap-fit, or other methods.

[0067] Of course, in other embodiments, the second limiting member 24 is not detachably connected to the second frame 23, such as by welding, glue fixation or other methods.

[0068] The following example uses the first object 1 having a limiting part 21:

[0069] The first object 1 includes a first frame and two first limiting members. The first frame is rotatably connected to the rotating end 31, and the first limiting members are detachably connected to the first frame and are provided with limiting parts 21. Preferably, the first limiting members can be connected to different positions of the first frame to change the distance between the first object 1 and the second object when the telescopic frame 3 abuts against the limiting parts 21.

[0070] Of course, in other embodiments, the first frame may be directly provided with a limiting part 21. The first limiting part and the first frame can be detachably connected in the same way as the detachable connection method described above, so as to achieve the same effect.

[0071] When using, Figure 1 and Figure 4 state and Figure 7 In contrast, when the rope breaks, the drying item 2 falls and causes the telescopic frame 3 to extend. The two rotating ends 31 or the two sliding ends 32 gradually approach the two limiting parts 21 until the two rotating ends 31 or the two sliding ends 32 abut against the two limiting parts 21, and the drying item 2 stops falling. At this time, the distance between the first object 1 and the second object is less than the maximum extension distance of the telescopic frame 3, thereby preventing the second object from falling and causing the distance between the first object 1 and the second object to reach the maximum extension distance of the telescopic frame 3 and impacting the object when the rope breaks.

[0072] Compared with the prior art, this embodiment has the following beneficial effects:

[0073] A lifting mechanism for a clothes drying machine is used for mounting on a first object 1, which is the clothes drying machine body or a ceiling, and includes a drying component 2 and a telescopic frame.

[0074] The drying rack 2 is used for drying clothes and other objects. The drying rack 2 is suitable for being connected to the drying machine body via a rope and is suitable for being driven by the drying machine body to rise and fall in the vertical direction. When the drying rack 2 is lowered, it is convenient for the user to place items, and when it is raised, it is convenient for drying.

[0075] The telescopic frame 3 includes at least two rotating ends 31 and at least two sliding ends 32. The rotating ends 31 are rotatably connected to one of the first object 1 and the drying piece 2, and the sliding ends 32 are slidably connected to the other.

[0076] The drying rack 2 is equipped with a limiting part 21. As the distance between the first object 1 and the drying rack 2 gradually increases, the two rotating ends 31 or the two sliding ends 32 gradually approach the limiting part 21. That is, the limiting part 21 is located on the sliding extension path of the telescopic frame 3, and the two rotating ends 31 or the two sliding ends 32 are adapted to ensure that the distance between the first object 1 and the drying rack 2 is less than the maximum extension distance of the telescopic frame 3 when they abut against the limiting part 21. This prevents the telescopic frame 3 from extending to its maximum distance due to the gravity of the drying rack 2 when the rope breaks, thus avoiding damage to the object or danger to personnel. The two rotating ends 31 or the two sliding ends 32 are adapted to lock against the limiting part 21, that is, interlocking is achieved through two limiting points, with only one side locked, ensuring that the drying rack 2 will not tilt further when the limiting part is engaged.

[0077] In one exemplary embodiment, the second object is provided with a sliding groove 22, the opening of the sliding groove 22 faces the first object 1, the sliding end 32 is adapted to slide in the sliding groove 22, and the second object is also provided with a limiting part 21 protruding from the groove wall of the sliding groove 22. The limiting part 21 is located in the sliding groove 22 and is hidden, which is more aesthetically pleasing.

[0078] In one exemplary embodiment, the second object includes a second frame 23 and two second limiting members 24. The second frame 23 is provided with a sliding groove 22. The second limiting members 24 are connected to the second frame 23 and have a limiting part 21 suitable for extending into the sliding groove 22. The separate manufacturing facilitates installation and allows the second limiting members 24 to be installed after the sliding end 32 is installed in the sliding groove 22. Thus, the sliding end 32 will not interfere with the second limiting members 24 during the installation process, which facilitates the installation of the sliding end 32.

[0079] In one exemplary embodiment, the second frame 23 is provided with a threaded hole 231 communicating with the sliding groove 22, and the second limiting member 24 is a fastener 242, which is threadedly connected to the threaded hole 231. The structure is simple, easy to process, and low in cost.

[0080] In one exemplary embodiment, the second frame 23 is provided with a threaded hole 231, and the second limiting member 24 includes a limiting block 241 and a fastener 242. The fastener 242 is adapted to be threadedly connected to the threaded hole 231. The fastener 242 can pass through the limiting block 241 and be threadedly connected to the threaded hole 231 to fix the limiting block 241 on the second frame 23. The limiting block 241 is provided with a limiting portion 21. The structure is simple, easy to process, and low in cost.

[0081] In one exemplary embodiment, the second frame 23 is provided with a plurality of threaded holes 231 arranged along the sliding extension direction of the sliding groove 22, so that the second limiting member 24 can be connected to different positions of the second frame 23 to change the distance between the first object 1 and the second object when the telescopic frame 3 abuts against the limiting part 21, which can be adjusted according to the floor height and has wider applicability.

[0082] In one exemplary embodiment, the second frame 23 is provided with a through hole, which communicates with the sliding groove 22. The second limiting member 24 includes a fastener 242 and a threaded mating member. The fastener 242 is adapted to pass through the through hole and be threadedly connected to the threaded mating member. The fastener 242 and the threaded mating member respectively clamp the surfaces where the two ends of the through hole are located. The structure is simple, easy to process, and low in cost.

[0083] In one exemplary embodiment, the through hole is an elongated hole extending along the sliding direction of the sliding groove 22, so that the second limiting member 24 can be connected to different positions of the second frame 23 to change the distance between the first object 1 and the second object when the telescopic frame 3 abuts against the limiting part 21. This can be adjusted according to the floor height and has wider applicability.

[0084] In one exemplary embodiment, the sliding groove 22 and the limiting part 21 are integrally formed, eliminating the need for installation.

[0085] In one exemplary embodiment, the first object 1 includes a first frame and two first limiting members. The first limiting members are detachably connected to the first frame and are provided with limiting portions 21. The first limiting members can be connected to different positions on the first frame to change the distance between the first object 1 and the second object when the telescopic frame 3 abuts against the limiting portion 21. Separate manufacturing facilitates processing and allows the first limiting members to be installed after the rotating end 31 is installed with the first frame, thus preventing interference with the first limiting members during the installation of the rotating end 31 and facilitating its installation. Furthermore, the first limiting members can be connected to different positions on the first frame to change the distance between the first object 1 and the second object when the telescopic frame 3 abuts against the limiting portion 21, allowing for adjustment according to floor height and wider applicability.

[0086] In one exemplary embodiment, a clothes drying machine includes a first object 1, a second object, and a telescopic frame 3. One of the first object 1 and the second object is the clothes drying machine body, and the other is a clothes drying component 2, which is used for drying clothes and other objects. The clothes drying machine body is adapted to drive the clothes drying component 2 to rise and fall in the vertical direction via a rope. When the clothes drying component 2 falls, it is convenient for the user to place items, and when it rises, it is convenient for drying.

[0087] The telescopic frame 3 includes at least two rotating ends 31 and at least two sliding ends 32. The rotating ends 31 are rotatably connected to the first object 1, and the sliding ends 32 are slidably connected to the second object. When the distance between the first object 1 and the second object changes (due to the extension and retraction of the rope), the frame is driven by the drying component 2, thereby changing the length of the telescopic frame 3 in the vertical direction, without causing the drying component 2 to move in the horizontal direction, and without affecting the lifting and lowering of the drying component 2.

[0088] The first object 1 or the second object is provided with a limiting part 21. As the distance between the first object 1 and the second object gradually increases, the two rotating ends 31 or the two sliding ends 32 gradually approach the limiting part 21. That is, the limiting part 21 is located on the sliding extension path of the telescopic frame 3. The telescopic frame 3 is adapted to make the distance between the first object 1 and the second object less than the maximum extension distance of the telescopic frame 3 when it abuts against the limiting part 21. This prevents the telescopic frame 3 from extending to the maximum distance due to the gravity of the drying item 2 when the rope breaks, thus avoiding damage to the object or danger to personnel. The two rotating ends 31 or the two sliding ends 32 are adapted to lock when they abut against the two limiting parts 21. That is, interlocking is achieved through two limiting points, with only one side locked, ensuring that the drying item 2 will not tilt further when the limiting part is in place.

[0089] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
