[0001] This utility model relates to the field of telescopic rod technology, and in particular to a telescopic rod and its selfie device. Background Technology
[0002] Telescopic poles are a core component of selfie sticks, tripods, and other equipment requiring telescopic functionality. A telescopic pole has multiple extendable joints that connect together, allowing adjustment of the device's height. Due to their wide range of applications, telescopic poles are a very popular accessory in the market.
[0003] Currently, the telescopic mechanism uses a limiting sleeve installed inside one end of the large telescopic component to prevent the smaller telescopic section from detaching from the large telescopic component. However, when the front end of the smaller telescopic section or the clamping mechanism installed on it is fully retracted into the large telescopic component, the front end of the smaller telescopic section or the clamping mechanism installed on it is behind the limiting sleeve. When it extends, it is easy to interfere with the rear end of the limiting sleeve, causing the telescopic rod to not extend or retract smoothly. Utility Model Content

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0033] This utility model embodiment provides a telescopic rod 11, such as Figures 1 to 10 As shown, the telescopic rod 11 includes a large telescopic joint 111, a small telescopic joint 112, and a first limiting sleeve 113. The first limiting sleeve 113 is installed on the inner wall of the front end of the large telescopic joint 111. The small telescopic joint 112 is telescopically inserted into the large telescopic joint 111 and passes through the first limiting sleeve 113. The small telescopic joint 112 can extend out from the front end of the large telescopic joint 111 or be completely retracted into the large telescopic joint 111. When the small telescopic joint 112 is completely retracted into the large telescopic joint 111, the front end of the small telescopic joint 112 is located in the first limiting sleeve 113.
[0034] Furthermore, when the small telescopic joint 112 is completely retracted into the large telescopic joint 111, the space from the front end of the small telescopic joint 112 to the front end of the large telescopic joint 111 within the first limiting sleeve 113 is the storage space 1131, which is used to store the first functional component 12 installed on one end of the telescopic rod 11.
[0035] The telescopic rod 11 of this utility model is provided with a first limiting sleeve 113. The first limiting sleeve 113 is installed on the inner wall of the front end of the large telescopic joint 111. When the telescopic joint is completely retracted into the large telescopic joint 111, the front end of the small telescopic joint 112 is located in the first limiting sleeve 113. The space between the front end of the small telescopic joint 112 and the front end of the large telescopic joint 111 in the first limiting sleeve 113 is left as a storage space 1131. The storage space 1131 can accommodate the first functional component 12 installed on one end of the telescopic rod 11, which facilitates the storage of the first functional component 12 and is conducive to the miniaturization of the equipment. When the small telescopic joint 112 and the first functional component 12 extend, they extend directly from the first limiting sleeve 113, which is not easy to interfere with or block the rear end of the first limiting sleeve 113, and the telescopic rod 11 extends and retracts smoothly.
[0036] Specifically, the telescopic rod 11 of this utility model can be applied to devices such as selfie devices 1, tripods, and telescopic fan rods, and is not specifically limited here. The first functional component 12 can be, for example, a fill light, a camera, a holding device, etc., and is not specifically limited here. The holding device can be, for example, a clamping device for fixing a mobile phone, a magnetic device, etc., and is not specifically limited here.
[0037] Specifically, when the small telescopic joint 112 is completely retracted into the large telescopic joint 111, the front end of the small telescopic joint 112 is located at the rear end within the first limiting sleeve 113. After the small telescopic joint 112 is retracted, the front end of the small telescopic joint 112 is located at the rear end within the first limiting sleeve 113. After the small telescopic joint 112 is retracted, most of the internal space within the first limiting sleeve 113 is freed up. The freed-up internal space can be used to store components installed at one end of the telescopic rod 11, such as clamping mechanisms and supplementary lights, which is beneficial for equipment miniaturization.
[0038] Specifically, the length of the first limiting sleeve 113 is 5cm to 12cm. The first limiting sleeve 113, with a length of 5cm to 12cm, provides sufficient and suitable internal space, preventing the front end of the small telescopic joint 112 from easily detaching from the first limiting sleeve 113 into the large telescopic joint 111. Simultaneously, it provides sufficient internal space to accommodate the first functional component 12 while maintaining the miniaturization of the device. More specifically, the length of the first limiting sleeve 113 is 7cm to 10cm. The first limiting sleeve 113, with a length of 7cm to 10cm, provides sufficient and suitable internal space.
[0039] Furthermore, the surface of the first limiting sleeve 113 is provided with a demolding groove 1132. The demolding groove 1132 facilitates the demolding of the first limiting sleeve 113. The first limiting sleeve 113 can be a plastic part, which can be integrally cylindrical or have two semi-arc-shaped pieces facing each other and installed on the inner wall of the large expansion joint 111. Specifically, the surface of the first limiting sleeve 113 has two first limiting grooves 1133 recessed inward in the axial direction. The two first limiting grooves 1133 are arranged opposite each other on the surface of the first limiting sleeve 113. On both sides of each first limiting groove 1133, there are multiple demolding grooves 1132 arranged at intervals along the axial direction of the first limiting sleeve 113. The first limiting grooves 1133 are engaged with the recessed grooves on the large expansion joint 111 to prevent the first limiting sleeve 113 from rotating. The first limiting grooves 1133 are engaged with the first limiting protrusions 1112 protruding along the axial direction on the inner wall of the large expansion joint 111.
[0040] The first limiting sleeve 113 has two opposing first locking protrusions 1134 on its surface. The large telescopic joint 111 has a first locking hole 1111 corresponding to the first locking protrusions 1134. The first locking protrusions 1134 are engaged in the first locking hole 1111 to install the first limiting sleeve 113. The rear end surface of the small telescopic joint 112 is equipped with two semi-circular positioning pieces 114. The semi-circular positioning pieces 114 have circumferentially extending, bulging bulges 1141 on their surfaces. The surfaces of the bulges 1141 abut against the inner wall of the large telescopic joint 111, enabling the small telescopic joint 112 to be positioned at any position during its extension and retraction. When the small telescopic joint 112 extends to its maximum length from the large telescopic joint 111, the semi-circular positioning pieces 114 abut against the rear end of the first limiting sleeve 113 to prevent the small telescopic joint 112 from detaching from the large telescopic joint 111. The inner wall of the semi-circular positioning piece 114 is provided with a second locking protrusion, and the small telescopic joint 112 is provided with a second locking hole corresponding to the second locking protrusion. The second locking protrusion is engaged in the second locking hole to realize the installation of the semi-circular positioning piece 114.
[0041] The front end of the small telescopic joint 112 is equipped with a second limiting sleeve 115. The second limiting sleeve 115 can abut against the semi-circular positioning piece 114 of the next telescopic joint inserted into the small telescopic joint 112, preventing the next telescopic joint from coming out of the small telescopic joint 112. The second limiting sleeve 115 is provided with two opposing third locking protrusions 1151. The front end of the small telescopic joint 112 is provided with a third locking hole 1121 corresponding to the third locking protrusions 1151. The third locking protrusions 1151 are engaged in the third locking hole 1121 to realize the installation of the second limiting sleeve 115.
[0042] like Figure 11 As shown, this utility model also discloses a selfie device 1, which includes the aforementioned telescopic rod 11.
[0043] Specifically, the selfie device 1 includes a first functional component 12, which is installed at one end of the telescopic rod 11. When the small telescopic joint 112 is completely retracted into the large telescopic joint 111, the space within the first limiting sleeve 113 from the front end of the small telescopic joint 112 to the front end of the large telescopic joint 111 is a storage space 1131, in which the first functional component 12 is stored. When the small telescopic joint 112 is completely retracted into the large telescopic joint 111, the space within the first limiting sleeve 113 from the front end of the small telescopic joint 112 to the front end of the large telescopic joint 111 remains as the storage space 1131. The storage space 1131 can accommodate the first functional component 12 installed at one end of the telescopic rod 11, facilitating the storage of the first functional component 12 and contributing to the miniaturization of the device. Specifically, the first functional component 12 can be, for example, a fill light, a camera, a holding device, etc., without specific limitations. The holding device can be, for example, a clamping device for fixing a mobile phone, a magnetic device, etc., without specific limitations.
