Description

Technical Field

[0001] The present application relates to the technical field of clothes drying machines, and in particular to a telescopic rod assembly and a clothes drying machine. Background Art

[0002] Existing clothes drying machines generally use a retractable drying rod structure. When there are many clothes to be dried, the drying rod can be extended to expand the drying space. When the clothes are to be dried, the drying rod can be shortened to realize the compact folding of the clothes drying machine. The retractable drying rod used in the existing clothes drying machine generally includes a main drying rod and two telescopic rods that can be extended and retracted from both ends of the main drying rod. The length of the two telescopic rods is limited by the length of the main drying rod. The sum of the retractable amounts of the two telescopic rods is bound to be less than the length of the main drying rod. Therefore, the existing clothes drying machine has defects: the extendable amount of the drying rod is short, and the expandable drying space is small. Utility Model Content

[0014] Optionally, along a direction perpendicular to the length direction of the fixed rod, the first telescopic rod and the second telescopic rod are staggered so that the first telescopic rod and the second telescopic rod partially overlap in a retracted state.

[0036] In order 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 described embodiments 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 creative work are within the scope of protection of this application.

[0037] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0038] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0039] Existing clothes drying machines generally use a retractable drying rod structure. When there are many clothes to be dried, the drying rod can be extended to expand the drying space. When the clothes are to be dried, the drying rod can be shortened to realize the compact folding of the clothes drying machine. The retractable drying rod used in the existing clothes drying machine generally includes a main drying rod and two telescopic rods that can be extended and retracted from both ends of the main drying rod. The length of the two telescopic rods is limited by the length of the main drying rod. The sum of the retractable amounts of the two telescopic rods is bound to be less than the length of the main drying rod. Therefore, the existing clothes drying machine has defects: the extendable amount of the drying rod is short, and the expandable drying space is small.

[0040] In order to overcome the above technical problems, Figure 1-11 As shown, this embodiment provides a telescopic rod assembly that can be used in a clothes drying machine as a drying rod. When retracting, the telescopic rod assembly can be shortened to reduce the occupied space. When drying clothes, the telescopic rod assembly can be extended to expand the drying space.

[0041] The telescopic rod assembly of this embodiment includes a fixed rod 1, a first telescopic rod 2 and a second telescopic rod 3. The fixed rod 1 includes a first end 11 and a second end 12 opposite to each other. The first telescopic rod 2 is telescopically mounted on the fixed rod 1, and can be telescopically mounted from the first end 11. The second telescopic rod 3 is telescopically mounted on the fixed rod 1, and can be telescopically mounted from the second end 12. In the retracted state, the first telescopic rod 2 and the second telescopic rod 3 partially overlap along the length direction of the fixed rod 1.

[0042] It can be understood that in the retracted state, along the length direction of the fixed rod 1, the first telescopic rod 2 and the second telescopic rod 3 partially overlap, indicating that the sum of the telescopic amounts of the first telescopic rod 2 and the second telescopic rod 3 will be greater than the length of the fixed rod 1. In the existing scheme, the longest case of the two telescopic rods is that the ends of the two telescopic rods are abutted after retraction, and the sum of the telescopic amounts of the two telescopic rods cannot exceed the length of the main drying rod itself. Obviously, when the fixed rod 1 of this scheme is set to be the same length as the existing main drying rod, the first telescopic rod 2 and the second telescopic rod 3 of this scheme can be set longer, and the length of the entire telescopic rod assembly is longer after extension, which can provide a larger drying space.

[0043] During specific implementation, those skilled in the art can set the overlap amount of the first telescopic rod 2 and the second telescopic rod 3 after contraction according to the drying requirements. The greater the overlap amount, the greater the telescopic length of the first telescopic rod 2 and the second telescopic rod 3.

[0044] In summary, based on the telescopic rod assembly structure of the present embodiment, a first telescopic rod 2 and a second telescopic rod 3 which can be telescoped from both ends are arranged in the fixed rod 1, and in the retracted state, the first telescopic rod 2 and the second telescopic rod 3 partially overlap, that is, the sum of the telescopic amounts of the first telescopic rod 2 and the second telescopic rod 3 will be greater than the length of the fixed rod 1 itself. It can be seen that, while keeping the length of the fixed rod 1 unchanged, the final extendable amount of the telescopic rod assembly of the present scheme is greater than that of the existing telescopic drying rod, that is, while maintaining the original compactness, integrity and aesthetics of the contraction, the expandable drying space is increased.

[0045] In one embodiment, the first telescopic rod 2 has a telescopic cavity, and in a retracted state, the second telescopic rod 3 is partially retracted into the telescopic cavity.

[0046] The first telescopic rod 2 and the second telescopic rod 3 of the present solution are arranged in a nested structure. After contraction, the second telescopic rod 3 can be contracted into the telescopic cavity of the first telescopic rod 2, thereby achieving the aforementioned purpose of partial overlap between the first telescopic rod 2 and the second telescopic rod 3.

[0047] By adopting a nested structure, the first telescopic rod 2 and the second telescopic rod 3 can be set to a structure with a cross section tending to be circular or square, so as to avoid the first telescopic rod 2 and the second telescopic rod 3 from being flattened, and ensure the bending resistance of the first telescopic rod 2 and the second telescopic rod 3 in all directions. In addition, when the second telescopic rod 3 is partially retracted into the telescopic cavity, a more stable structure is formed between the first telescopic rod 2 and the second telescopic rod 3, which helps to prevent accidental expansion or damage during transportation or storage.

[0048] In the present application, the first telescopic rod 2 and the second telescopic rod 3 respectively have a telescopic end and an insertion end. The insertion end is the end of the first telescopic rod 2 and the second telescopic rod 3 that is first inserted into the cavity of the fixed rod 1 during installation, and the telescopic end is the end of the first telescopic rod 2 and the second telescopic rod 3 that remains outside the fixed rod 1 after installation. When telescoping, the first telescopic rod 2 and the second telescopic rod 3 can be pushed and pulled to telescope through the telescopic end.

[0049] In one embodiment, referring to Figure 7-8 A conical guide end 5 is installed at the insertion end of the second telescopic rod 3, and the guide end 5 is used to guide the second telescopic rod 3 to retract into the telescopic cavity.

[0050] The guide end 5 is designed to be conical, and this shape can easily guide at the entrance of the telescopic cavity, reducing jamming or damage caused by shape mismatch. The guide end 5 plays a key guiding role in the contraction process, ensuring that the second telescopic rod 3 can be smoothly and accurately contracted into the telescopic cavity of the first telescopic rod 2, thereby optimizing the user's operating experience.

[0051] In one embodiment, a stop block 51 protruding relative to the side wall of the second telescopic rod 3 is provided on one side of the guide end 5, and the stop block 51 is used to limit the insertion end of the second telescopic rod 3 from detaching from the fixed rod 1; an avoidance groove 21 for avoiding the stop block 51 is provided on the side of the first telescopic rod 2 corresponding to the stop block 51.

[0052] This solution utilizes the structure of the guide end 5, and forms a stopper 51 on its side to limit the second telescopic rod 3 from completely separating from the fixed rod 1, so as to ensure the reliability of the telescopic structure. Even under the condition of external force or vibration, it is not easy to accidentally separate. The guide end 5 of this structure has the functions of guiding and limiting, which is conducive to the simplification of the number of parts of the telescopic rod assembly structure. It can be understood that, correspondingly, a structure capable of forming a mutual limit with the stopper 51 needs to be provided at the second end 12 of the fixed rod 1.

[0053] An avoidance groove 21 is provided on one side of the first telescopic rod 2 corresponding to the stop block 51 . When the second telescopic rod 3 is retracted into the telescopic cavity, the avoidance groove 21 provides sufficient activity space for the stop block 51 to avoid collision and friction therebetween.

[0054] In one embodiment, an inner plug 4 is installed at the insertion end of the first telescopic rod 2, and the inner plug 4 is used to limit the insertion end of the first telescopic rod 2 from being separated from the fixed rod 1. The center of the inner plug 4 has an insertion hole 41 that is adapted to the outer dimensions of the second telescopic rod 3, and the second telescopic rod 3 is retracted into the telescopic cavity through the insertion hole 41.

[0055] The design of the inner plug 4 ensures that the first telescopic rod 2 can be stably maintained in the fixed rod 1 during the telescopic process, avoiding safety hazards caused by accidental detachment. Similarly, a structure that can form a mutual limit with the inner plug 4 needs to be provided at the first end 11 of the fixed rod 1.

[0056] Reference Figure 7 The insertion hole 41 at the center of the inner plug 4 is adapted to the outer dimensions of the second telescopic rod 3. This design not only ensures that the second telescopic rod 3 can smoothly enter the telescopic cavity, but also avoids jamming or damage caused by size mismatch. In addition, after contraction, the inner diameter of the telescopic cavity of the first telescopic rod 2 can be set to be larger than the outer diameter of the second telescopic rod 3, and the inner plug 4 is used to provide support for the second telescopic rod 3 to avoid the problem of direct contact and friction between the first telescopic rod 2 and the second telescopic rod 3 during the telescopic process.

[0057] In one embodiment, referring to Figure 7 and Fig.10 The inner plug 4 has an inner retaining ring 42 that abuts against the end surface of the first telescopic rod 2, and the insertion end of the first telescopic rod 2 is restricted in the fixed rod 1 by the inner retaining ring 42; and the outer dimensions of the inner retaining ring 42 are adapted to the inner cavity of the fixed rod 1 to guide the insertion end of the first telescopic rod 2 to move linearly in the fixed rod 1.

[0058] The outer dimensions of the inner retaining ring 42 are adapted to the inner cavity of the fixed rod 1. This adaptability not only ensures that the inner retaining ring 42 can move smoothly in the fixed rod 1, but also provides support and guidance for guiding the linear movement of the first telescopic rod 2. In specific settings, the outer dimensions of the first telescopic rod 2 can be set to be smaller than the inner cavity dimensions of the fixed rod 1. After installation, based on the support of the inner retaining ring 42, the first telescopic rod 2 will not contact the inner wall surface of the fixed rod 1, which can ensure that the first telescopic rod 2 and the fixed rod 1 will not rub during the entire telescopic process, thereby avoiding problems such as telescopic jamming, wear, and noise caused by the friction between the first telescopic rod 2 and the fixed rod 1.

[0059] In another embodiment, along a direction perpendicular to the length direction of the fixed rod 1, the first telescopic rod 2 and the second telescopic rod 3 are staggered so that the first telescopic rod 2 and the second telescopic rod 3 partially overlap in the retracted state.

[0060] This mode is different from the aforementioned nested arrangement of the first telescopic rod 2 and the second telescopic rod 3. In this mode, the first telescopic rod 2 and the second telescopic rod 3 are staggered, which can also make them avoid each other when they are retracted, so that they can partially overlap. In specific arrangement, the staggered arrangement of the first telescopic rod 2 and the second telescopic rod 3 can be in the form of up-down staggered arrangement or front-back staggered arrangement.

[0061] In one embodiment, a guide sleeve 6 is installed on the first end 11 and the second end 12 respectively. The guide sleeve 6 installed on the first end 11 guides the linear extension and retraction of the first telescopic rod 2, and the guide sleeve 6 installed on the second end 12 guides the linear extension and retraction of the second telescopic rod 3.

[0062] Specifically, a guide sleeve 6 is respectively provided at the first end portion 11 and the second end portion 12 of the fixed rod 1 to guide the linear extension and retraction of the first telescopic rod 2 and the second telescopic rod 3, thereby ensuring the smoothness of the extension and retraction process of the first telescopic rod 2 and the second telescopic rod 3, and at the same time providing reliable support for the extension of the first telescopic rod 2 and the second telescopic rod 3, thereby reducing the inclination of the first telescopic rod 2 and the second telescopic rod 3 after extension.

[0063] It can be understood that in the guide sleeve 6 installed at the first end 11, the size of the guide hole at the center thereof is adapted to the outer dimensions of the first telescopic rod 2, preferably a clearance fit; in the guide sleeve 6 installed at the second end 12, the size of the guide hole at the center thereof is adapted to the outer dimensions of the second telescopic rod 3, preferably a clearance fit.

[0064] In one embodiment, the guide sleeve 6 includes a connected sleeve portion 61 and an outer retaining ring, the sleeve portion 61 extends into the fixed rod 1, and the outer retaining ring abuts against the end surface of the fixed rod 1. The sleeve portions 61 located at both ends can respectively limit the insertion ends of the first telescopic rod 2 and the second telescopic rod 3 from detaching from the fixed rod 1.

[0065] Based on the structure of the guide sleeve 6, the guide sleeve 6 is used as a plug structure that can limit the first telescopic rod 2 and the second telescopic rod 3 from completely separating from the fixed rod 1, that is, it can cooperate with the aforementioned internal plug 4 and the stop block 51 to form a limit, thereby achieving the purpose of maintaining the stability of the telescopic rod assembly structure and avoiding damage or danger caused by accidental separation.

[0066] In one embodiment, referring to Fig.11A plurality of supporting ribs 611 are convexly formed on the outer wall surface of the sleeve portion 61 , and the supporting ribs 611 are closely attached to the inner wall surface of the fixing rod 1 .

[0067] A plurality of supporting ribs 611 are convexly arranged on the outer wall of the sleeve portion 61. The supporting ribs 611 cooperate with the inner cavity of the fixing rod 1 to reduce the contact area between the sleeve portion 61 and the inner wall of the fixing rod 1, so that the sleeve portion 61 can be installed in the fixing rod 1 by interference fit, so that the sleeve portion 61 and the fixing rod 1 can be tightly connected after installation, avoiding the risk of the guide sleeve 6 shaking or even detaching from the fixing rod 1. Preferably, the insertion end of each supporting rib 611 is set in a wedge shape to facilitate the guide to be installed in the fixing rod 1.

[0068] In one embodiment, the sleeve portion 61 is provided with two spaced-apart avoidance holes 612, and an elastically deformable elastic deformation portion 613 is formed on the sleeve portion 61 between the two avoidance holes 612. A limiting buckle 614 is provided on the outer wall surface of the elastic deformation portion 613, and the first end portion 11 and the second end portion 12 are respectively provided with limiting holes 13 cooperating with the limiting buckle 614, and the limiting buckle 614 is buckled with the limiting hole 13 to limit the guide sleeve 6 from being separated from the fixing rod 1.

[0069] An avoidance hole 612 is opened on the sleeve portion 61 to form an elastic deformation portion 613 that can be deformed independently, and a limit buckle 614 is set on the elastic deformation portion 613. During installation, the limit buckle 614 can squeeze the elastic deformation portion 613 inwardly due to the squeezing of the fixed rod 1. When the limit buckle 614 is installed to the position of the limit hole 13, the elastic deformation portion 613 returns to its original state, and the limit buckle 614 is buckled with the limit hole 13. A mutually buckled mechanical hard limit structure is formed between the sleeve portion 61 and the fixed rod 1, which can effectively enhance the reliability of the installation of the guide sleeve 6.

[0070] In summary, this solution enhances the reliability of the installation of the guide sleeve 6 without destroying the guiding function of the guide sleeve 6, while maintaining the advantage of the guide sleeve 6 being easy to install.

[0071] It can be understood that the formation of the escape holes 612 on the sleeve portion 61 to form the elastic deformation portion 613 is not limited to the formation of only two escape holes 612 at intervals, and more escape holes 612 may also be formed. Fig.11 The form shown is to open two spaced air-avoiding holes 612 separately. In other forms, a third air-avoiding hole 612 may be opened at the ends of the two air-avoiding holes 612 to connect the two air-avoiding holes 612. In this case, the hole position connected by the three air-avoiding holes 612 is a U-shaped hole structure, which should also be understood to be included in the protection scope of this application.

[0072] In one embodiment, a first gear locking member for locking the extension of the first telescopic rod 2 is provided between the first telescopic rod 2 and the fixed rod 1, and a second gear locking member for locking the extension of the second telescopic rod 3 is provided between the second telescopic rod 3 and the fixed rod 1.

[0073] The first gear locking member and the second gear locking member are respectively provided to lock the extension length of the first telescopic rod 2 and the second telescopic rod 3, so that the user can conveniently lock the first telescopic rod 2 and the second telescopic rod 3 at the required extension length according to the use requirements.

[0074] When specifically configured, the first gear locking member and the second gear locking member may be in the form of, but not limited to, magnetic locking, spring buckle locking, etc. Taking the first gear locking member as an example, a spring buckle may be provided on the guide sleeve 6 installed at the first end 11, and a plurality of buckle holes cooperating with the spring buckle may be provided at intervals along the length of the first telescopic rod 2. When the first telescopic rod 2 is extended to the point where any buckle hole is aligned with the spring buckle, the extended length of the first telescopic rod 2 is locked. A first magnetic block may also be provided on the guide sleeve 6 installed at the first end 11, and a plurality of second magnetic blocks may be provided at intervals along the length of the first telescopic rod 2. When the first telescopic rod 2 is extended to the point where any second magnetic block is aligned with the first magnetic block, the extended length of the first telescopic rod 2 is locked.

[0075] On the other hand, a clothes drying machine is provided, comprising the telescopic rod assembly mentioned above.

[0076] By using the telescopic rod assembly of the present embodiment as the drying rod of the clothes drying machine, the drying space can be further expanded and the drying amount can be increased while maintaining the original compactness of the clothes drying machine.
