[0040] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.
[0041] Please refer to Figure 1-Figure 8 The clothes drying rod end cover connection mechanism 100 and clothes drying machine 1000 provided in the embodiment of the utility model can solve the above-mentioned problems, which will be described in detail below.
[0042] refer to Figure 1-Figure 3 The drying rod end cover connection mechanism 100 is used for a clothes drying machine 1000, and includes a drying rod 110, an end cover 130, an expansion member 140 and a locking member 150; the expansion member 140 is accommodated in the end cover 130, the end cover 130 is connected to one end of the drying rod 110, a part of the end cover 130 and the expansion member 140 are both accommodated in the drying rod 110, the locking member 150 penetrates the expansion member 140 and is spirally matched with the expansion member 140, so that the expansion member 140 is pressed against the end cover 130, and at least two first oblique teeth 1321 are annularly arranged on the end cover 130, and at least two first oblique teeth 1321 are pressed against the locking member 150;
[0043] The end cover 130 is provided with a limiting platform 131 , and the limiting platform 131 abuts against the expansion member 140 to prevent the expansion member 140 from being separated from the end cover 130 .
[0044] When disassembly and packaging is required, the locking member 150 can be rotated out for separate packaging, and the expansion member 140 will not fall into the inner cavity of the drying rod 110 and get stuck due to the support of the limit platform 131, thereby preventing the expansion member 140 from completely separating from the end cover member 130, reducing material waste.
[0045] Furthermore, the locking member 150 is locked by forming the first oblique teeth 1321 , so that the locking member 150 and the expansion member 140 will not be easily reversely loosened when tightened and locked, thereby ensuring locking stability.
[0046] It should be noted that, during the assembly process, the expansion member 140 can be first placed in the end cover member 130, and then the end cover member 130 and the expansion member 140 can be placed together into the inner cavity of the clothes drying rod 110, and then one end of the locking member 150 can be inserted into the end cover member 130 and spirally matched with the expansion member 140.
[0047] In this embodiment, the positions of the locking member 150 and the expansion member 140 that cooperate with each other can be provided with external threads and internal threads respectively, and the two can be screwed together by threaded connection. When an external force is applied to the locking member 150 to drive the locking member 150 to rotate, the threaded connection can be used to convert the rotational motion into the axial movement of the expansion member 140. When the expansion member 140 moves in a direction close to the end cover 130, its outer wall will press against the inner wall of the end cover 130; when the expansion member 140 moves in a direction away from the connecting member 200, its outer wall will be separated from the inner wall of the end cover 130.
[0048] refer to Figure 3 and Figure 4 In order to improve the limiting effect of the limiting platform 131 on the expansion member 140, an anti-dropping buckle 141 can be provided on the expansion member 140, and the anti-dropping buckle 141 cooperates with the limiting platform 131. A guiding inclined surface 1411 is formed on the side of the anti-dropping buckle 141 away from the limiting platform 131, and the guiding inclined surface 1411 is provided to guide the expansion member 140 in the process of placing the end cover 130.
[0049] In addition, the guide slope 1411 has a first end 1411a and a second end 1411b arranged in sequence along the direction close to the end cover 130, the outer diameter of the first end 1411a is smaller than the outer diameter of the second end 1411b and the inner diameter of the limit platform 131, and the outer diameter of the second end 1411b is larger than the inner diameter of the limit platform 131.
[0050] In the present embodiment, the number of the limit platforms 131 and the anti-drop buckles 141 are both two, and the two limit platforms 131 are symmetrically arranged in the circumferential direction of the end cover 130, and the two anti-drop buckles 141 are symmetrically arranged in the circumferential direction of the expansion member 140; of course, in other embodiments of the present invention, from the perspective of improving the limiting stability, the number of the limit platforms 131 and the anti-drop buckles 141 can also be three, four, six groups, etc., and there is no limitation on the specific number of the limit platforms 131 and the anti-drop buckles 141.
[0051] refer to Figure 4An expansion slope 142 is formed on the outer wall of the expansion member 140 . The expansion slope 142 is staggered with the anti-drop buckle 141 . The expansion slope 142 is used to abut against the inner wall of the end cover 130 .
[0052] Specifically, the expansion slope 142 is an inclined surface, so that the expansion member 140 has a conical structure, and the small diameter end of the cone is closer to the connecting member 200 than the large diameter end.
[0053] Furthermore, by misaligning the expansion slope 142 and the anti-drop buckle 141, the expansion member 140 can be flexibly switched between two states: abutting against the end cover member 130 and detaching from the end cover member 130 through the anti-drop buckle 141 and cooperating with the limit platform 131, so that the two will not interfere with each other.
[0054] Furthermore, there are at least two expansion slopes 142 , and avoidance grooves 143 are formed between adjacent expansion slopes 142 . The avoidance grooves 143 and the anti-trip buckles 141 are correspondingly arranged in the circumferential direction of the expansion member 140 . The limit platform 131 is accommodated in the avoidance grooves 143 and abuts against the side walls of the avoidance grooves 143 .
[0055] When the expansion slope 142 abuts against the end cover 130, the expansion member 140 will move toward the connecting member 200, thereby causing the anti-drop buckle 141 and the limit platform 131 to move away from each other. The setting of the avoidance groove 143 can accommodate the limit platform 131 therein, which can avoid abutting interference with the limit platform 131 and can also prevent the expansion member 140 from rotating by cooperating with the limit platform 131 through the side wall of the avoidance groove 143.
[0056] refer to Figure 1 and Figure 2 A guide ring 132 is provided on the inner side of the end cover 130 , and the locking member 150 is accommodated in the guide ring 132 . The end surface of the guide ring 132 close to the connecting member 200 is provided with at least two first oblique teeth 1321 in an annular shape, and the first oblique teeth 1321 abut against the locking member 150 .
[0057] During the assembly process, the guide ring 132 can be provided to guide and position the locking member 150, thereby preventing the locking member 150 from deflecting relative to the end cover member 130 when penetrating the connecting member 200, so that the locking member 150 can cooperate with the expansion member 140 more quickly during installation.
[0058] Furthermore, because the locking member 150 and the expansion joint are spirally matched, when the locking member 150 rotates in the first direction, the connection depth with the expansion member 140 can become deeper, and when the locking member 150 rotates in the second direction, the connection depth with the expansion member 140 can become shallower until the locking member 150 is separated from the expansion member 140. By setting the first bevel tooth 1321, the direction from the low point to the high point of the first bevel tooth 1321 is the first direction, which facilitates the locking member 150 and the expansion member 140 to be tightened, and the high point to the low point of the first bevel tooth 1321 is the second direction, thereby preventing the locking member 150 from easily rotating in the second direction and loosening the connection with the expansion member 140.
[0059] refer to Figure 1 and Figure 6 In order to improve the positioning accuracy and connection reliability of the drying rod 110 and the end cover 130, a positioning hole 111 can be opened on the side wall of the drying rod 110, and a positioning buckle 133 is formed on the outer wall of the end cover 130, and the positioning buckle 133 is accommodated in the positioning hole 111.
[0060] In the present embodiment, the number of positioning holes 111 and positioning buckles 133 are both two groups, the two positioning holes 111 are symmetrically opened on the drying rod 110, and the two positioning buckles 133 are symmetrically arranged on the end cover 130; of course, in other embodiments of the present invention, the number of positioning holes 111 and positioning buckles 133 can also be one, three, five, etc., and there is no limitation on the specific number of groups of the two.
[0061] refer to Figure 1 and Figure 5 The locking member 150 can be a single-head extension structure. The locking member 150 includes a locking portion 151, a self-locking portion 152 and a first locking rod portion 153 connected in sequence. The locking portion 151 is abutted against the connecting member 200. The first self-locking portion 152 passes through the connecting member 200. The end surface of the first self-locking portion 152 away from the locking portion 151 is annularly provided with at least two second oblique teeth 1521. The second oblique teeth 1521 cooperate with the first oblique teeth 1321. The first locking rod portion 153 is accommodated in the guide ring 132 and spirally cooperates with the expansion member 140.
[0062] In this embodiment, the outer diameter of the locking head portion 151 is larger than the outer diameter of the first self-locking portion 152 and larger than the outer diameter of the first locking rod portion 153, so that the connecting member 200 can be provided with a connecting hole 210, and the connecting hole 210 is a countersunk hole. The locking head portion 151 is accommodated in the large diameter section of the countersunk hole, and the first locking rod portion 153 is used to be accommodated in the guide ring 132 and spirally cooperate with the expansion member 140. The self-locking portion 152 is convenient for cooperation with the first bevel tooth 1321 by setting the second bevel tooth 1521, thereby improving the self-locking performance of the locking member 150 and the expansion member 140.
[0063] refer to Figure 6 and Figure 7The locking member 150 can also be a double-headed extension structure. The locking member 150 includes a second locking rod portion 154, a self-locking portion 152 and a first locking rod portion 153 connected in sequence. The second locking rod portion 154 passes through the connecting member 200. The self-locking portion 152 is annularly provided with at least two second bevel teeth 1521 on the end surface near the first locking rod portion 153. The second bevel teeth 1521 cooperate with the first bevel teeth 1321. The first locking rod portion 153 is accommodated in the guide ring 132 and is spirally matched with the expansion member 140.
[0064] In this embodiment, the outer diameters of the second locking rod 154 and the first locking rod 153 can be consistent, and the outer diameter of the self-locking portion 152 is larger than the outer diameters of the second locking rod 154 and the first locking rod 153. The second locking rod 154 can be interference fit with the connector 200 or threaded connection.
[0065] Furthermore, because the clothes-drying rod 110 has a certain extension length, which is significantly longer than the extension length of the connecting member 200 in the axial direction of the clothes-drying rod 110, the extension length of the second locking rod portion 154 in the outer cover 300 can be shorter than the extension length of the first locking rod portion 153 in the clothes-drying rod 110, thereby ensuring that the clothes-drying rod 110 accommodating the first locking rod portion 153 has sufficient supporting strength.
[0066] refer to Figure 8 The embodiment of the utility model further provides a clothes drying machine 1000, comprising a connecting member 200, an outer cover 300 and a clothes drying rod end cover connecting mechanism 100, wherein the connecting member 200 is installed on the outer cover 300. The clothes drying machine 1000 may also include a host, wherein a telescopic driving member and a drying driving member are disposed in the host, and the two cooperate to realize the clothes drying operation. Both ends of the connecting member 200 cooperate with the clothes drying rod 110, and the outer cover 300 is covered on the outside of the high part of the connecting member 200. The clothes drying machine 1000 includes a clothes drying rod end cover connecting mechanism 100, which has all the functions of the clothes drying rod end cover connecting mechanism 100.
[0067] In summary, the clothes drying rod end cover connection mechanism 100 and clothes drying machine 1000 provided by the embodiments of the present utility model have at least the following advantages:
[0068] (1) When it is necessary to disassemble and pack, the locking member 150 can be rotated out for separate packing, and the expansion member 140 will not fall into the inner cavity of the drying rod 110 and get stuck due to the support of the limit platform 131, thereby preventing the expansion member 140 from completely separating from the end cover 130, thereby reducing material waste.
[0069] (2) By providing the matching first bevel teeth 1321 and second bevel teeth 1521, the guide ring 132 can cooperate with the self-locking portion 152 to achieve a self-locking function, so that the locking member 150 can be tightened in the forward direction while avoiding the phenomenon of loosening in the reverse direction.
[0070] (3) When using a double-headed locking member 150, by limiting the relationship between the extension lengths of the second locking rod portion 154 and the first locking rod portion 153, better support strength can be provided for a longer drying rod 110 to prevent the drying rod 110 from bending and deforming due to being too long.
[0071] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
