Description

Technical Field

[0001] The present application relates to the technical field of supporting parts, and in particular to a clothes drying machine and a spring telescopic rod structure thereof. Background Art

[0002] Clothes drying machines often use telescopic structures to expand the drying range. For example, the telescopic structure is configured in the basic drying rod, the quilt drying rod or the expandable attachment, so that the volume of the drying rod part can be hidden and compressed as much as possible when not in use for easy storage. When in use, it can be fully extended to obtain more drying space. However, the existing telescopic rod structure can achieve longitudinal expansion and contraction, and can also withstand longitudinal tension and pressure to a certain extent, but its radial force is weak, especially when the degree of elongation is large, when it acts as a horizontal telescopic structure, the load-bearing capacity is weak and cannot meet the drying requirements.

[0027] The embodiments of the present application are described below in conjunction with the drawings in the present application. It should be understood that the implementation methods described below in conjunction with the drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application and do not constitute a limitation on the technical solutions of the embodiments of the present application.

[0028] Those skilled in the art will appreciate that, unless expressly stated, the "said" and "the" used herein may also include plural forms. It should be further understood that the term "including" used in the specification of the present application refers to the presence of the features, operations, elements and / or components, but does not exclude the implementation of other features, information, data, steps, operations, elements, components and / or combinations thereof supported by the technical field. The term "and / or" used herein refers to at least one of the items defined by the term, for example, "A and / or B" may be implemented as "A", or as "B", or as "A and B".

[0029] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0030] refer to Figures 1 to 3The spring telescopic rod structure of the present application includes a plug 1, a base 2, and a spring 3 whose two ends are respectively connected to the plug 1 and the base 2. The spring 3 is telescopic under the limitation of the skeleton rod. One possible implementation method is that the skeleton rod includes an inner sleeve 4 sleeved in the inner cavity of the spring 3 and an outer sleeve 5 sleeved on the outer surface of the spring 3. It is obvious that the outer diameter of the inner sleeve 4 is smaller than the inner diameter of the outer sleeve 5. By adjusting the lengths of the inner sleeve 4 and the outer sleeve 5, the inner sleeve 4 can be partially or completely sleeved in the outer sleeve 5. In the embodiment of the present application, the lengths of the inner sleeve 4 and the outer sleeve 5 are respectively greater than half of the length of the spring 3 but less than the total length of the spring 3, so that the inner sleeve 4 and the outer sleeve 5 always have overlapping sections, which can ensure that the longitudinal structure of the spring telescopic rod structure has continuity and will not loosen under normal use. Furthermore, the minimum length of the overlapping section can be limited to ensure the strength of the spring telescopic rod structure and avoid breakage in the overlapping section. In a possible embodiment, the minimum length of the overlapping section is set to be within the range of 1 / 10 to 1 / 8 of the total length of the spring 3.

[0031] In this embodiment, the ends of the inner sleeve 4 and the outer sleeve 5 that are away from each other are translated synchronously with the two ends of the spring 3, so that the inner sleeve 4 and the outer sleeve 5 can be nested with each other following the compression or release of the spring 3, and the nesting makes the length of the overlapping section of the inner sleeve 4 and the outer sleeve 5 change, thereby the linear distance between the ends of the inner sleeve 4 and the outer sleeve 5 that are away from each other changes accordingly, so that the total length of the spring telescopic rod structure changes. When the spring 3 is compressed by an external force, the inner sleeve 4 can be nested inside the outer sleeve 5, thereby shortening the linear distance between the two ends of the outer sleeve 5 and the inner sleeve 4, and shortening the spring telescopic rod structure; when the spring 3 is in a state of evacuating or reducing the external force, the elastic potential energy accumulated by itself is released, and the linear distance between the two ends of the outer sleeve 5 and the inner sleeve 4 is stretched, and the spring telescopic rod structure is extended.

[0032] One possible implementation is that one end of the inner sleeve 4 is fixedly connected to the base 2, and one end of the outer sleeve 5 is fixedly connected to the plug 1, whereby the distance between the plug 1 and the base 2 is the telescopic length of the spring telescopic rod structure of this embodiment, and the maximum extendable length of the spring telescopic rod structure is determined by the minimum length of the overlapping section of the inner sleeve 4 and the outer sleeve 5, and the minimum compressible length of the spring telescopic rod structure is determined by the longer one of the inner sleeve 4 and the outer sleeve 5. Another possible implementation is that one end of the inner sleeve 4 is fixedly connected to the plug 1, and one end of the outer sleeve 5 is fixedly connected to the base 2, and those skilled in the art can make a choice according to the needs of the usage scenario.

[0033] The plug 1 and the base 2 in this embodiment are only used to limit the two ends of the spring telescopic rod structure, and the specific structure should be adjusted according to the usage scenario. In a possible implementation, the plug 1 and the base 2 are respectively provided with a fixing column for fixing the end of the spring 3, which is used to insert into the inner cavity of the spring 3 to achieve fixation, or wrap the body of the spring 3 to achieve fixation. Optionally, such a fixing column can be made of a screw, and the thread on the surface of the screw can increase the friction surface for fixing the spring 3, or the fixing column can be made of a pin column, which is convenient for integral molding with other components, or an axial blind hole or through hole is opened inside the pin column to fix the end of the spring 3. In this embodiment, a screw is set at the plug 1 as a fixing column, and a pin column is set at the base 2 as a fixing column.

[0034] Furthermore, in order to improve the smoothness of the active nesting between the inner sleeve 4 and the outer sleeve 5, it is preferred to set the inner sleeve 4 and the outer sleeve 5 as a tube body with a circular cross section, which, on the one hand, adapts to the cross-sectional profile of the spring 3, and on the other hand, reduces the hard collision between the outer wall of the inner sleeve 4 and the inner wall of the outer sleeve 5. In addition, there is a spring 3 blocking the inner sleeve 4 and the outer sleeve 5, but a certain distance should be maintained between the inner sleeve 4 and the spring 3, and between the outer sleeve 5 and the spring 3, so as to achieve clearance fit, reduce the friction between the inner sleeve 4, the spring 3 and the outer sleeve 5, and reduce the telescopic resistance of the spring telescopic rod structure. In other implementations, the cross-sectional shape of the outer sleeve 5 can be implemented in other ways, but it should meet the principle of clearance fit with the spring 3.

[0035] Another possible implementation is that the skeleton rod includes an outer shell 6 and a fixed rod (not shown) sleeved on the outer surface of the spring 3, and the outer shell 6 can be nested inside the fixed rod so that the outer shell 6 and the fixed rod can slide relative to each other, thereby realizing the extension and retraction of the spring telescopic rod structure. The cross-sectional shapes of the outer shell 6 and the fixed rod can be the same or different, but those skilled in the art can understand that when the cross-sectional shapes of the outer shell 6 and the fixed rod are the same, the degree of tightness of the fit between the two can be higher. When the cross-sectional shapes of the outer shell 6 and the fixed rod are different, different functional structures can be configured on the outer shell 6 and the fixed rod in a targeted manner to improve the versatility of the spring telescopic rod structure of the present application.

[0036] The length of the outer shell 6 and the fixed rod is similar to that of the inner sleeve 4 and the outer sleeve 5. The length of the outer shell 6 and the fixed rod is respectively greater than half of the length of the spring 3 but less than the total length of the spring 3, so that there is an overlap between the outer shell 6 and the fixed rod, ensuring that the connection between the outer shell 6 and the fixed rod is always continuous within the normal telescopic stroke of the spring 3, and the longer one of the outer shell 6 and the fixed rod determines the shortest length of the spring telescopic rod structure after being compressed. The ends of the outer shell 6 and the fixed rod that are far away from each other can also be fixed and assembled using the plug 1 and the base 2.

[0037] Optionally, the spring telescopic rod structure of the embodiment of the present application can be provided with a shell 6 and / or a fixed rod on the basis of configuring the inner sleeve 4 and the outer sleeve 5, and the shell 6 or the fixed rod is sleeved on the outer surface of the outer sleeve 5. The shell 6 and the fixed rod can serve as a protective shell of the spring telescopic rod structure on the one hand, and other accessories can be extended and installed on the basis of the shell 6 and the fixed rod on the other hand, so that the spring telescopic rod structure can cooperate with other mechanical devices.

[0038] In this embodiment, only the outer shell 6 is configured on the basis of the inner sleeve 4 and the outer sleeve 5. The outer shell 6 is a rectangular cross-section tube. One end of the outer shell 6 is fixedly connected to the plug 1. At the same time, the outer sleeve 5 is fixedly connected to the plug 1, and the inner wall of the outer shell 6 and the outer wall of the outer sleeve 5 are kept in a gap without contact. Therefore, the plug 1 simultaneously fixes the spring 3, the outer sleeve 5 and the outer shell 6. Relatively, the base 2 simultaneously fixes the spring 3 and the inner sleeve 4. Further, in order to ensure the stability of the outer shell 6 structure, a gasket 7 is set at the other end of the outer shell 6. Figure 4 In this embodiment, the liner 7 includes two through structures, and the two through structures are connected as a whole by a connecting strip, so that the liner 7 covers the surface of the outer shell 6. Specifically, the liner 7 includes a through hole 71 through structure for the spring 3 (including the inner sleeve 4) to penetrate, which serves as a free end, and also includes a first structural hole 72 through structure for the outer shell 6 to penetrate, which serves as a connecting end. Furthermore, a positioning ring is also provided on the inner side of the free end of the liner 7 for the end of the outer sleeve 5 to abut against, thereby, the length of the outer shell 6 is equal to the length of the outer sleeve 5, and the outer shell 6 moves with the movement of the outer sleeve 5. When the length of the outer sleeve 5 is greater than the length of the inner sleeve 4, the shortest length of the spring telescopic rod structure after being compressed is limited by the length of the outer sleeve 5.

[0039] Another possible implementation is that the plug 1 simultaneously fixes the spring 3, the inner sleeve 4 and the outer shell 6, and correspondingly, the base 2 simultaneously fixes the spring 3 and the outer sleeve 5. In this case, the free end of the liner 7 needs to be provided with a through hole 71 through which the outer sleeve 5 passes, and the inner side of the free end does not need to be provided with a structure for positioning the spring 3 or the inner sleeve 4, and the connecting end is provided with a first structural hole 72 through which the outer shell 6 passes. Thus, the outer shell 6 moves with the movement of the inner sleeve 4. At this time, the shortest length of the spring telescopic rod structure after being compressed is limited by the longest one of the inner sleeve 4, the outer sleeve 5 and the outer shell 6. When the length of the inner sleeve 4 is greater than the length of the outer shell 6, or when the length of the outer sleeve 5 is greater than the outer shell 6, the outer shell 6 cannot completely cover the outer sleeve 5 when the compression degree of the spring telescopic rod structure is the largest. When the length of the outer shell 6 is greater than the length of the inner sleeve 4 and the length of the outer sleeve 5, respectively, the shortest length of the spring telescopic rod structure compressed is limited by the outer shell 6, and the outer sleeve 5 and the inner sleeve 4 do not reach the shortest compression degree.

[0040] The shortest compressed dimension of the spring telescopic rod structure can be set by setting the lengths of the inner sleeve 4 , the outer sleeve 5 and the outer shell 6 to meet actual application requirements.

[0041] Furthermore, the through structure of the gasket 7 is defined by a structural wall. Optionally, the connecting end of the gasket 7 forms a first structural hole 72 consistent with the contour of the shell 6 through the structural wall. Further, the free end of the gasket 7 is added with a structural wall having a circular hole at the very end on the basis of the first structural hole 72, and the diameter of the circular hole is adapted to the spring 3 or the outer sleeve 5.

[0042] refer to Figure 5 Furthermore, a sleeve 8 is disposed adjacent to the front end of the connecting end of the gasket 7 for positioning and protecting the gasket 7. A possible implementation method is that the sleeve 8 includes a second structural hole 81 adapted to the outer shell 6. The second structural hole 81 is formed by a structural wall to be consistent with the contour of the outer shell 6, that is, the shape of the second structural hole 81 is the same as or similar to the shape of the first structural hole 72. Furthermore, a fixing plate 82 is extended from the edge of the second structural hole 81 for limiting or serving as a connecting structure. The extension direction and specific structure of the fixing plate 82 can be set according to actual needs. Assuming that the plug 1 is defined as the front end and the base 2 is defined as the rear end, the sleeve 8 is disposed at the front end of the gasket 7, which can resist the external force from the front end or the compression displacement from the plug 1 to the base 2, and avoid direct force damage to the bushing. The sleeve 8 can also be used as a limiting member to define the lower limit of compression. The cooperation between the sleeve 8 and the liner 7 can protect the overlapping section of the inner sleeve 4 and the outer sleeve 5. In one embodiment, the length of the liner 7 matches the shortest state of the overlapping section. Furthermore, a supporting structure can be provided under the liner 7 to facilitate supporting the entire spring telescopic rod structure.

[0043] Accessories or accessory connectors may also be adaptively arranged at other positions of the housing 6 to match the application of the spring telescopic rod structure. Further, the cross-sectional profile of the housing 6 may also be replaced with other shapes, such as a profile with grooves or convex strips, and correspondingly, the shapes of the first structural hole 72 and the second structural hole 81 need to be adaptively adjusted.

[0044] The specific structure of the fixed rod can also adapt to the application scenario, but it needs to be adapted to the shell 6. At least, the fixed rod has an inner cavity for the shell 6 with the liner 7 and the over sleeve 8 to be embedded, the liner 7 and the over sleeve 8 can be fixed in the fixed rod, and the shell 6 can penetrate the liner 7 and the over sleeve 8 to achieve the compression and extension of the spring telescopic rod. In other embodiments, the fixed rod can be an independent rod structure, or a longitudinal cavity structure in other non-rod structures.

[0045] The application implementation of the spring telescopic rod structure of the present application includes application to a clothes drying machine, which includes a main machine and a clothes drying rod assembly. The clothes drying rod assembly includes a main clothes drying rod, a quilt drying rod and a clothes drying net according to its functions, wherein at least one of the main clothes drying rod, the quilt drying rod and the clothes drying net can adopt the spring telescopic rod structure of the present application.

[0046] In summary, a spring telescopic rod structure of the present application includes a plug, a base, and a spring whose two ends are respectively connected to the plug and the base, and the inside and / or outside of the spring are provided with skeleton rods that are mutually nested in the length direction to limit the telescopic direction of the spring. The spring telescopic rod structure of the present application utilizes an inner sleeve and an outer sleeve, or an outer shell and a fixed rod as a guide structure for the spring to be telescopic, and also serves as a supporting skeleton, which can strengthen the upper limit of radial force, and is conducive to increasing the upper limit of the weight of the drying rod.
