Description

Technical Field

[0001] This utility model relates to the field of hanging devices, and more specifically, to a telescopic rod mechanism and a hanging device. Background Technology

[0002] In related technologies, telescopic rods generally consist of an inner tube and an outer tube, with the outer tube slidably fitted onto the outside of the inner tube. The inner tube can slide relative to the outer tube to extend or retract into it, thereby adjusting the length of the telescopic rod. To prevent the end of the inner tube located inside the outer tube from protruding from the end of the outer tube, an extrusion process is generally used to extrude the end of the outer tube, reducing the inner diameter of one end of the outer tube to be smaller than the outer diameter of the inner tube. However, the extrusion process is complex, has high processing costs, and low production efficiency.

[0003] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for a telescopic rod mechanism.

[0027] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0028] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0030] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0032] According to one embodiment of this application, a telescopic rod mechanism is provided. For example... Figure 1 and Figure 2 As shown, the telescopic rod mechanism includes a tube 1, a rod 2, and a limiting member 3. The tube 1 is fitted around the outer periphery of the rod 2, and the rod 2 is slidable relative to the tube 1. The limiting member 3 is disposed inside the tube 1 and can abut against the first end 22 of the rod 2 to prevent the first end 22 from extending beyond the rod 2.

[0033] In this example, by placing the limiting member 3 inside the tube body 1, the limiting member 3 abuts against the first end 22 of the rod body 2, thereby restricting the first end 22 from extending outside the tube body 1. This structure is simple, easy to assemble, and can improve production efficiency and reduce production costs.

[0034] Figure 1 and Figure 2 As shown, it should be noted that the first end 22 of the rod 2 is one end along the axial direction of the rod 2. The first end 22 extends into the tube 1 and can slide along the axial direction of the tube 1. The limiting member 3 can be fixedly installed inside the tube 1. When the first end 22 slides inside the tube 1 and is about to extend out of the tube 1, it can abut against the limiting member 3, thereby limiting the first end 22 from extending out of the tube 1.

[0035] In this example, tube 1 is a hollow tube structure to facilitate the sliding installation of rod 2 within tube 1. Rod 2 can also be a hollow tube structure, thereby reducing the overall weight of the telescopic rod mechanism and saving materials.

[0036] It should also be noted that the specific dimensions of the tube body 1 and the rod body 2, such as their length and outer diameter, can be determined by those skilled in the art based on the actual situation, and are not specifically limited here.

[0037] It should also be noted that the materials of rod 2 and tube 1 can be stainless steel, carbon steel or aluminum alloy, etc., which can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0038] In one example, such as Figure 1 and Figure 2 As shown, the limiting member 3 includes a limiting ring, the outer wall of which is fitted against the inner wall of the tube body 1.

[0039] like Figure 1 and Figure 2 As shown, in this example, the limiting member 3 can be a limiting ring, that is, the limiting member 3 is a ring-shaped structure. The outer wall of the limiting ring can fit tightly against the inner wall of the tube 1, so that the limiting ring can be fixedly installed inside the tube 1. One end of the limiting ring along the axial direction is suitable for abutting against the first end 22 of the rod 2. By setting the limiting member 3 as a ring-shaped structure, the elastic performance of the limiting member 3 can be improved, so that the limiting member 3 can be compressed more easily, thereby facilitating the assembly of the limiting member 3 into the inside of the tube 1, and also facilitating the insertion of other objects into the inside of the tube 1 through the central opening of the ring structure. The ring structure can be a circular ring structure, a structure with an outer circle and an inner square, or other ring structures.

[0040] In one example, the limiting member 3 is a flexible member. For example, the limiting member 3 can be made of materials such as silicone, rubber, or engineering plastics. By making the limiting member 3 a flexible member, it can be compressed more easily, thereby facilitating the assembly of the limiting member 3 into the interior of the tube body 1. Moreover, there can be greater pressure between the flexible member and the inner wall of the tube body 1, thereby increasing the friction between the flexible member and the inner wall of the tube body 1 and improving the reliability of the limiting member 3 in resisting the rod body 2.

[0041] Of course, the limiting member 3 can also be a rigid part such as metal. The limiting member 3 can be fixed inside the tube body 1 by snap-fit, fastener screw connection, welding, or bonding. Those skilled in the art can determine the method according to the actual situation, and no specific limitation is made here.

[0042] In one example, the limiting member 3 is detachably connected to the tube body 1. When the limiting member 3 is damaged, it can be replaced, thereby improving the overall service life of the telescopic rod mechanism. For example, the limiting member 3 can be made of materials such as silicone, rubber, or engineering plastics. By making the limiting member 3 a flexible component, it can be easily compressed, facilitating its assembly into the tube body 1. The limiting member 3 has a ring-shaped structure; when disassembly is required, it can be pulled out of the tube body 1 by hooking the inner ring of the limiting member 3 with a hook. Alternatively, a large pushing force can be applied to the limiting member 3 by the rod 2 to push it out of the tube body 1.

[0043] In one example, such as Figure 1 and Figure 2 As shown, the outer wall of the rod body 2 is provided with a first protruding ring portion 21, which can contact the inner wall of the tube body 1.

[0044] like Figure 1 and Figure 2 As shown, in this example, the outer wall of the rod 2 protrudes radially outward with a first protruding ring 21. The first protruding ring 21 can contact the inner wall of the tube 1, and when the rod 2 moves axially along the tube 1, the first protruding ring 21 can slide along the inner wall of the tube 1. By providing the first protruding ring 21 on the outer wall of the rod 2, the contact area between the rod 2 and the tube 1 can be reduced, thereby reducing the friction between the rod 2 and the tube 1, so that the rod 2 can slide more smoothly relative to the tube 1. Furthermore, by having the first protruding ring 21 contact the inner wall of the tube 1, the rod 2 can be prevented from tilting relative to the tube 1, which would result in insufficient contact between the first end 22 and the limiting member 3. For example, the first end 22 may have point contact with the limiting member 3, which would cause uneven force on the limiting member 3, making it easy for the rod 2 to push and affecting the stability of the telescopic rod mechanism. It is understandable that the rod 2 contacts the inner wall of the tube 1 through the first protruding ring 21, which makes the coaxiality of the rod 2 and the tube 1 higher. Therefore, when the first end 22 presses the limiting member 3, the first end 22 can contact the limiting member 3 with its entire end face, thereby improving the limiting stability of the limiting member 3 on the rod 2.

[0045] In this example, multiple first protruding ring portions 21 can be provided at intervals along the axial direction of the rod body 2. For example, two, three, or four first protruding ring portions 21 can be provided at intervals. Those skilled in the art can determine this according to the actual situation, and no specific limitation is made here.

[0046] It should be noted that the first protruding ring portion 21 can be integrally formed with the rod body 2. For example, the outer wall of the rod body 2 can be compressed and protrude outward to form the first protruding ring portion 21. Alternatively, the first protruding ring portion 21 can be sleeved on the rod body 2 and fixedly connected to the rod body 2 by welding or bonding. Those skilled in the art can determine the specific method according to the actual situation, and no specific limitation is made here.

[0047] In one example, the inner wall of the tube 1 is provided with a second protruding ring portion that protrudes inward. The second protruding ring portion is adapted to abut against the first protruding ring portion 21, and the first protruding ring portion 21 is located between the second protruding ring portion and the limiting member 3.

[0048] In this example, the tube 1 has a second protruding ring portion that protrudes radially inward on the side away from the limiting member 3. The first protruding ring portion 21 is located between the second protruding ring portion and the limiting member 3. The second protruding ring portion is adapted to abut against the side of the first protruding ring portion 21 away from the first end 22, thereby preventing the rod 2 from detaching from the tube 1.

[0049] It should be noted that after the rod 2 is slidably connected to the tube 1, the second convex ring can be integrally formed by pressing the tube 1 inward, or the second convex ring can also be set inside the tube 1 and fixedly connected to the inner wall of the tube 1 by welding or bonding. Those skilled in the art can decide according to the actual situation, and no specific limitation is made here.

[0050] According to another embodiment of this utility model, a hanging device is provided. For example... Figures 3 to 5 As shown, the hanging device includes the telescopic rod mechanism described in the above embodiment. The telescopic rod mechanism includes a tube 1, a rod 2, and a limiting member 3. The tube 1 is fitted around the outer periphery of the rod 2, and the rod 2 can slide relative to the tube 1. The limiting member 3 is disposed inside the tube 1, and the limiting member 3 can abut against the first end 22 of the rod 2 to restrict the first end 22 from extending beyond the tube 1. By placing the limiting member 3 inside the tube 1 and using the limiting member 3 to abut against the first end 22 of the rod 2 to restrict the first end 22 from extending beyond the tube 1, this structure is simple, easy to assemble, and can improve production efficiency and reduce production costs.

[0051] In one example, such as Figures 3 to 5 As shown, the hanging device also includes a hook 4, which is connected to the end of the telescopic rod mechanism.

[0052] like Figures 3 to 5As shown, there can be two hooks 4, each connected to one end of the telescopic rod mechanism along the axial direction. That is, one hook 4 can be located at one end of the tube body 1, and the other hook 4 can be located at one end of the rod body 2. The hooks 4 can be hung on supporting structures such as walls or doors. The telescopic rod mechanism can be used to hang items, such as clothes hangers, clothes, scarves, etc. Those skilled in the art can determine the appropriate method based on the actual situation, and no specific limitation is made here.

[0053] In one example, such as Figure 3 and Figure 4 As shown, the hanging device also includes a first connector 5, which is rotatably connected to the end of the telescopic rod mechanism, and the hook 4 is movably connected to the first connector 5.

[0054] like Figure 3 and Figure 4 As shown, in this example, the first connecting member 5 can be rotatably connected to the telescopic rod mechanism via the second connecting member 6. That is, the second connecting member 6 can be an end cap, which can be sleeved on the end of the telescopic rod mechanism. For example, the end cap can be detachably sleeved on the end of the tube body 1. The tube body 1 can be provided with a mounting hole, and the end cap is provided with a corresponding mating hole 61. When the end cap is sleeved on the end of the tube body 1, the mating hole 61 corresponds to the mounting hole. At this time, by inserting fasteners 7 such as rivets through the mating hole 61 and the mounting hole, the end cap can be securely connected to the end of the tube body 1. At this time, the fasteners 7 are located between the limiting member 3 and the end of the tube body 1. Therefore, the fasteners 7 can also prevent the limiting member 3 from detaching from the tube body 1, further improving the limiting stability of the limiting member 3 on the rod body 2. In addition, the first connecting member 5 can be rotatably connected to the second connecting member 6 by means of rivet connection or other methods.

[0055] like Figure 3 As shown, it should be noted that the first connecting member 5 is provided with a through hole, through which the rod of the hook 4 can be movably inserted. After the rod of the hook 4 is movably inserted through the through hole, a first stop 41 is provided at one end of the rod of the hook 4, and a second stop 42 is provided at one end of the hook portion of the hook 4. The second stop 42 is detachably installed at one end of the hook portion of the hook 4. The outer diameter of the first stop 41 and the second stop 42 is larger than the inner diameter of the through hole, thereby preventing the hook 4 from detaching from the first connecting member 5.

[0056] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.

[0057] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
