Description

Technical Field

[0001] The utility model belongs to the technical field of clothes drying rods, and in particular relates to a telescopic rod and a rounding machine for clothes drying racks. Background Art

[0002] Electric clothes drying racks are now a must-have product for every home. They can be controlled by electricity to drive the clothes drying rod to rise and fall. In order to meet the needs of drying clothes, existing clothes drying rods are all set to be retractable, such as Figure 1 As shown, in order to prevent the inner tube from detaching from the outer tube, a plastic anti-detachment sheet is sleeved on the outer periphery of the inner tube so that the inner tube and the anti-detachment sheet are relatively fixed, and the inner tube is prevented from detaching from the outer tube by restricting the anti-detachment sheet.

[0003] However, in the above solution, since the anti-drop sheet is clamped on the inner tube via the protrusion, the protrusion is easily broken by stress during the use of the inner tube, resulting in failure.

[0004] Therefore, it is necessary to design a telescopic rod and a rounding machine for a clothes drying rack to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a telescopic rod and a rounding machine for a clothes drying rack, so as to solve the technical problems described in the background technology.

[0006] In order to solve the above technical problems, the utility model provides a telescopic rod for a clothes drying rack, which comprises: an outer tube, an extension tube, and a tube cap; wherein one end of the extension tube is slidably arranged in the outer tube; at least one annular protrusion is arranged on the end of the extension tube located in the outer tube; the tube cap is sleeved on the end of the outer tube to block the annular protrusion.

[0007] Furthermore, two annular protrusions are used, and a stable gap is left between the two annular protrusions.

[0008] Furthermore, the outer diameter of the annular protrusion is slidably matched with the inner diameter of the outer tube.

[0009] Furthermore, the pipe cap is provided with an avoidance hole for the extension pipe to pass through.

[0010] Furthermore, the outer diameter of the annular protrusion is greater than the inner diameter of the avoidance hole.

[0011] Furthermore, the annular protrusion is integrally formed with the extension tube.

[0012] The utility model also provides a rounding machine for processing an extension tube, which comprises: a convex rod and a concave wheel; wherein the outer diameter of the convex rod is smaller than the inner diameter of the extension tube, and is used to sleeve the extension tube; the convex rod and the concave wheel are suitable for tightening the extension tube on the convex rod, and forming an annular protrusion on the extension tube by rotation.

[0013] Furthermore, the protruding rod is provided with an annular ridge matched with the annular protrusion; and the concave wheel is provided with an annular groove matched with the annular ridge.

[0014] Furthermore, the rounding machine also includes: a mounting frame; a driving motor for driving the convex rod to rotate is arranged on the mounting frame, and a cylinder for driving the concave wheel to rise and fall is arranged on the mounting frame.

[0015] Furthermore, a support frame is arranged on the mounting frame; the cam wheel is rotatably arranged on the support frame; and the cylinder is suitable for driving the support frame to rise and fall.

[0016] The beneficial effect of the utility model is that the annular protrusion of the telescopic rod of the clothes drying rack is integrally formed with the extension tube, and the annular protrusion is processed into the end of the extension tube by a rounding machine, thereby replacing the existing anti-slip sheet. Since the annular protrusion is integrated with the extension tube, its strength is much greater than that of the anti-slip sheet. At the same time, the annular protrusion is raised all around the extension tube. Compared with the protrusion on half side of the anti-slip sheet, it is more evenly stressed and not easy to be damaged.

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] like Figures 1 to 3 As shown, this embodiment provides a telescopic rod for a clothes drying rack, which includes: an outer tube 1, an extension tube 2, and a tube cap 3; wherein one end of the extension tube 2 is slidably arranged in the outer tube 1; at least one annular protrusion 21 is arranged on the end of the extension tube 2 located in the outer tube 1; the tube cap 3 is sleeved on the end of the outer tube 1 to block the annular protrusion 21.

[0034] In this embodiment, the annular protrusion 21 and the extension tube 2 are formed integrally.

[0035] In this embodiment, specifically, the annular protrusion 21 is integrally formed with the extension tube 2, and the annular protrusion 21 is processed at the end of the extension tube 2 by a rounding machine, thereby replacing the existing anti-slip sheet. Since the annular protrusion 21 is integral with the extension tube 2, its strength is much greater than the anti-slip sheet. At the same time, the annular protrusion 21 is raised all around the extension tube 2. Compared with the protrusion on half of the anti-slip sheet, it is more evenly stressed and not easily damaged.

[0036] like Figure 4 As shown, in this embodiment, two annular protrusions 21 are used, and a stable gap 22 is left between the two annular protrusions 21 .

[0037] In this embodiment, specifically, two annular protrusions 21 are used with a stable gap 22 left therebetween, so that the outer end of the extension tube 2 can maintain stability after being pulled outward, thereby preventing the outer end of the extension tube 2 from tilting downward.

[0038] like Figure 5 , Figure 6 As shown, in this embodiment, the outer diameter D1 of the annular protrusion 21 is slidably matched with the inner diameter of the outer tube 1; the tube cap 3 is provided with an avoidance hole 31 for the extension tube 2 to pass through; the inner diameter of the avoidance hole 31 is slidably matched with the diameter of the extension tube 2;

[0039] In this embodiment, specifically, the sliding fit means that there is a gap between the two, but the gap is very small, so that it can be ensured that the extension tube 2 will not tilt downward significantly after being pulled out.

[0040] In this embodiment, the outer diameter D1 of the annular protrusion 21 is greater than the inner diameter D2 of the avoidance hole 31 .

[0041] like Figure 7 As shown, this embodiment also provides a rolling machine for processing an extension tube, which includes: a profiled convex rod 41 and a profiled concave wheel 42; wherein the outer diameter of the profiled convex rod 41 is smaller than the inner diameter of the extension tube 2, and is used to sleeve the extension tube 2; the profiled convex rod 41 and the profiled concave wheel 42 are suitable for tightening the extension tube 2 on the profiled convex rod 41, and forming an annular protrusion 21 on the extension tube 2 by rotation.

[0042] In this embodiment, specifically, when processing the extension tube 2, the extension tube 2 is sleeved on the protruding rod 41, and then the annular protrusion 21 is formed by the cooperation of the protruding rod 41 and the concave wheel 42.

[0043] In this embodiment, the protruding rod 41 is provided with an annular edge 411 matched with the annular protrusion 21 ; and the concave wheel 42 is provided with an annular groove 421 matched with the annular edge 411 .

[0044] In this embodiment, the rounding machine further comprises: a mounting frame 43; a driving motor 44 for driving the convex rod 41 to rotate is disposed on the mounting frame 43, and a cylinder 45 for driving the concave wheel 42 to rise and fall is disposed on the mounting frame 43.

[0045] In this embodiment, a support frame 46 is disposed on the mounting frame 43; the cam wheel 42 is rotatably disposed on the support frame 46; and the cylinder 45 is suitable for driving the support frame 46 to rise and fall.

[0046] In this embodiment, specifically, after the extension tube 2 is sleeved on the protruding rod 41, the cylinder 45 drives the cam wheel 42 to rise until it contacts the extension tube 2, and then the driving motor 44 drives the protruding rod 41 to rotate. At the same time, the rotation of the protruding rod 41 drives the extension tube 2 to rotate, and the cam wheel 42 also rotates accordingly, thereby forming the annular protrusion 21.

[0047] To sum up, the annular protrusion 21 of the telescopic rod of the clothes drying rack is integrally formed with the extension tube 2, and the annular protrusion 21 is processed at the end of the extension tube 2 by a rounding machine, thereby replacing the existing anti-slip sheet. Since the annular protrusion 21 is integral with the extension tube 2, its strength is much greater than that of the anti-slip sheet. At the same time, the annular protrusion 21 is raised all around the extension tube 2. Compared with the protrusion on half of the anti-slip sheet, it is more evenly stressed and not easily damaged.
