Description

Technical Field

[0001] This utility model belongs to the field of telescopic pole technology, and in particular relates to a telescopic pole anti-sway structure. Background Technology

[0002] Telescopic poles are often used as support poles. Because they have telescopic adjustment functions, the relative position of the items supported by the telescopic pole can be adjusted, so they are widely used in daily life and work.

[0003] Telescopic rods consist of a tubular outer rod and a tubular or rod-shaped inner rod. The inner rod is inserted into the outer rod, and the telescopic length is adjusted by relative sliding. Therefore, a gap exists between the outer and inner rods. Existing telescopic rods generally have plastic fasteners at the top of the outer rod to secure the adjusted inner and outer rods. However, a ring-shaped gap still exists between the bottom of the inner rod and the inner circumference of the outer rod. For example, Chinese invention patent CN106089880A discloses a camera holder telescopic rod where a gap exists between the bottom of the inner rod and the outer rod, allowing the bottom of the inner rod to move in any direction, easily causing the entire inner rod to wobble. This wobble is particularly pronounced when a heavy object is supported at the top of the inner rod. Utility Model Content

[0004] The purpose of this invention is to provide an anti-sway structure for telescopic rods, solving the problem of gaps between the inner and outer rods, which allow the bottom of the inner rod to move in any direction and easily cause the entire inner rod to sway. The technical solution adopted by this invention is as follows:

[0005] A telescopic pole anti-sway structure includes an inner pole and an outer pole that are plugged together. The bottom of the inner pole is provided with an anti-sway device, and the outer periphery of the inner pole and the inner periphery of the outer pole abut against each other through the anti-sway device.

[0006] Furthermore, the anti-sway device is a tubular component.

[0007] Furthermore, the anti-sway device and the inner rod are secured with fasteners.

[0008] Furthermore, the anti-sway device is provided with countersunk holes that are compatible with fasteners.

[0009] Furthermore, the fasteners are screws, pins, or rivets.

[0010] Furthermore, the ratio of the height of the outer rod to the height of the anti-sway device is less than or equal to 25:1.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. By installing an anti-sway device between the inner and outer rods, the gap between the bottom of the inner rod and the outer rod can be filled, thereby preventing the bottom of the inner rod from moving arbitrarily and causing the entire inner rod to wobble. This allows the rod to remain stable when supporting heavy objects, providing a good user experience.

[0013] 2. The smaller the height of the anti-sway device, the smaller the contact area between the anti-sway device and the inner and outer rods, resulting in greater local pressure and causing deformation of the outer rod. In severe cases, the paint on the outer rod may peel off. Setting the ratio of the height H of the outer rod to the height h of the anti-sway device to less than or equal to 25:1 and manufacturing the outer rod and anti-sway device according to this ratio can enable the telescopic rod to bear a load of about 30 kg, and the paint on the outer rod will not peel off.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0020] The connections mentioned in this utility model are divided into fixed connections and detachable connections. Fixed connections, also known as non-detachable connections, include but are not limited to conventional fixed connection methods such as folded connections, riveted connections, adhesive connections, and welded connections. Detachable connections include but are not limited to conventional disassembly methods such as bolt connections, snap-fit ​​connections, pin connections, and hinge connections. When a specific connection method is not explicitly defined, it is assumed that at least one existing connection method can be found to achieve this function, and those skilled in the art can choose according to their needs. For example, a welded connection can be chosen for a fixed connection, and a bolted connection can be chosen for a detachable connection.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0022] Example: Figures 1-4 As shown, a telescopic rod anti-sway structure includes an inner rod 2 and an outer rod 1 that are plugged together. The bottom 21 of the inner rod 2 is provided with an anti-sway device 3, and the outer periphery of the inner rod 2 and the inner periphery of the outer rod 1 are abutted by the anti-sway device 3.

[0023] Figure 4 An example of this utility model supporting a heavy object is given. The heavy object is a display device. The lower part of the inner rod 2 is inserted into the outer rod 1. If there is a gap between the outer circumference of the inner rod 2 and the inner circumference of the outer rod 1, the bottom of the inner rod 2 will move arbitrarily, causing the inner rod 2 to shake as a whole.

[0024] By setting an anti-sway device 3 between the inner rod 2 and the outer rod 1, the gap between the bottom of the inner rod 2 and the outer rod 1 can be filled, thereby preventing the bottom of the inner rod 2 from moving arbitrarily and causing the inner rod 2 to shake as a whole. This allows the present invention to remain stable when supporting heavy objects, providing users with a good experience.

[0025] The anti-sway device 3 is a tubular component. In this embodiment, the anti-sway device 3 is located at the bottom 21 of the inner rod 2. After the lower part of the inner rod 2 is inserted into the outer rod 1 for assembly, the anti-sway device 3 is located between the outer periphery of the inner rod 2 and the inner periphery of the outer rod 1, thereby preventing the bottom 21 of the inner rod 2 from moving arbitrarily and causing the entire inner rod 2 to shake. The movement range of the anti-sway device 3 located at the bottom 21 of the inner rod 2 is limited to the height H of the outer rod 1. In addition, the anti-sway device 3 and the inner rod 2 are fixed by fasteners 4.

[0026] The anti-sway device 3 has a countersunk hole 31, which is adapted to the cap of the fastener 4. The purpose is to ensure that the cap of the fastener 4 is within the countersunk hole 31 and does not protrude from the anti-sway device 3, thus avoiding obstruction of assembly. The fastener 4 is a screw, pin, or rivet.

[0027] The ratio of the height of the outer rod 1 to the height of the anti-sway device 3 is less than or equal to 25:1. The smaller the height of the anti-sway device 3, the smaller the contact area between the anti-sway device 3 and the inner rod 2 and the outer rod 1, resulting in greater local pressure, which can cause deformation of the outer rod 1. In severe cases, the paint on the outer rod 1 may peel off. In the study of anti-sway of telescopic poles, researchers found that setting the ratio of the height H of the outer rod 1 to the height h of the anti-sway device 3 to less than or equal to 25:1, and manufacturing the outer rod 1 and the anti-sway device 3 according to this ratio, can enable the telescopic pole to bear a load of about 30 kg, and the outer rod 1 will not deform or peel off.

[0028] The above embodiments are merely illustrative examples of the present utility model and do not limit its scope of protection. Those skilled in the art can make partial changes to it, as long as they do not exceed the spirit and essence of the present utility model, they are all within the scope of protection of the present utility model.
