[0024] The present application provides a telescopic leg, which is applicable to a holder or the like, particularly a holder for supporting a load device such as a camera, a mobile phone or a tablet computer, but is not limited thereto.

[0025] 1 to 5, in an embodiment of the present application, the telescopic leg includes a support handle 10, a telescopic arm assembly 20, and a friction assembly 30, the support handle 10 is provided with a storage cavity 10a, the telescopic arm assembly 20 includes at least a first telescopic arm, the first telescopic arm is provided in the storage cavity 10a so as to be slidably switchable between a closed position and an open position, the friction assembly 30 is provided at a sliding end of the first telescopic arm and elastically abuts against a cavity wall of the storage cavity 10a to provide a sliding friction force, when in the closed position at least a portion of the first telescopic arm is stored in the storage cavity 10a, and when in the open position the first telescopic arm extends out of the storage cavity 10a.

[0026] In this embodiment, the support handle 10 may be rod-shaped, and its cross section may be circular, square, polygonal, etc. The support handle 10 may be manufactured by integral molding or may be a separate assembly structure, and is not particularly limited here.

[0027] The telescopic arm assembly 20 may include a first telescopic arm that is extendable and scalable from the support handle 10, or a second telescopic arm that is extendable and scalable from the first telescopic arm, and may also include a third telescopic arm or more support arms, with the latter telescopic arm being extendable and scalable from the former. That is, the telescopic leg of the present application may have a two-stage, three-stage or multi-stage telescopic structure, which can suit more terrains and meet the usage needs of more applications.

[0028] Here, the first telescopic arm may be a single member, or may be assembled from two or more members, and is not particularly limited here.

[0029] The friction assembly 30 may include at least one friction block, which may be made of a plastic or metal part with relatively high wear resistance. The surface of the friction block may be smoothed or may be coated with lubricant, thereby improving the smoothness of sliding of the first telescopic arm.

[0030] In the technical solution of the present application, the telescopic leg includes a support handle 10, a telescopic arm assembly 20, and a friction assembly 30. The support handle 10 is provided with a storage cavity 10a. The telescopic arm assembly 20 includes at least a first telescopic arm. The first telescopic arm is slidably disposed within the storage cavity 10a when in a closed position or an open position. The friction assembly 30 is provided at the sliding end of the first telescopic arm and elastically abuts against the cavity wall of the storage cavity 10a to provide a sliding friction force. When in the closed position, the first telescopic arm is stored within the storage cavity 10a, and when in the open position, the first telescopic arm extends out of the storage cavity 10a. In this way, the support length of the telescopic legs can be adjusted, and the size of the support surface can be adjusted (the support surface of the holder is formed by the end connecting lines of three or more telescopic legs at its bottom), thereby adapting to more usage terrains and improving applicability.

[0031] Referring primarily to FIG. 5 , a friction assembly 30 is provided at the sliding end of the first telescopic arm, and the friction assembly 30 elastically abuts against the cavity wall of the receiving cavity 10a. During sliding, the friction assembly 30 constantly presses against the cavity wall of the receiving cavity 10a of the support handle 10 due to the action of elastic force, providing a sliding friction force. This allows the first telescopic arm to slide smoothly and stably, avoiding direct contact of the first telescopic arm with the receiving cavity 10a, reducing wear on the sliding end of the first telescopic arm, and extending the service life of the first telescopic arm.

[0032] In order to improve assembly convenience, save materials, and reduce manufacturing costs, referring to FIGS. 3 to 5, in one embodiment, the first telescopic arm may include a leg base 21, a first telescopic rod 22, and a second telescopic rod 23 arranged opposite the first telescopic rod 22, with one end of the first telescopic rod 22 and the second telescopic rod 23 fixed to the leg base 21, and the other end of the first telescopic rod 22 and the second telescopic rod 23 slidably arranged within the receiving cavity 10a via a friction assembly 30.

[0033] Here, the middle of the first telescopic arm is hollow, which can save materials and reduce manufacturing costs.

[0034] In this embodiment, the number of the accommodating cavities 10a may be two, and both of the accommodating cavities 10a are arranged along the longitudinal direction of the bottom cover 12. The width of each accommodating cavity 10a can be adapted to the width of the corresponding telescopic rod to prevent the telescopic rods from shifting position during the process of sliding and extending, thereby improving the smoothness and stability of the sliding.

[0035] 4 and 5, in one embodiment, in order to further improve the stability and smoothness of the sliding of the first telescopic arm and to avoid wear of its sliding end, the friction assembly 30 may include a first friction block 31, a second friction block 32, and a first elastic member 33, and sinking bases 201 are provided on both sides of the sliding end of the first telescopic arm, and through holes are drilled in the sinking bases 201 for passing through connecting members, the first friction block 31 and the second friction block 32 are respectively attached to the two sinking bases 201 and fixedly connected via connecting members, and the first elastic member 33 is provided between the first friction block 31 and the second friction block 32. Here, the connecting members may be screws, bolts, etc., and are not limited herein.

[0036] In this embodiment, the first elastic member 33 may be a spring or other member having a certain elasticity, and is not limited here.

[0039] 6 to 11, in another embodiment, the telescopic leg may further include a lock assembly 40, which is provided on the support handle 10 and is used to restrict the sliding of the first telescopic arm when the first telescopic arm is in the open position. In this way, the stability of the telescopic leg when supporting an object can be improved, and the telescopic arm can be prevented from automatically sliding.

[0040] 9 to 11, in this embodiment, the lock assembly 40 may include a button 41 and a second elastic member 42, a button hole is provided in the support handle 10, the button 41 is attached to the button hole and abuts against the inner wall of the support handle 10 via the second elastic member 42, a sliding edge 211 is provided on both the first telescopic rod 22 and the second telescopic rod 23 of the first telescopic arm, an engagement position 212 connected to the sliding edge 211 is provided on the first telescopic arm or the friction assembly 30, an insertion end of the button 41 is provided on the sliding edge 211, and an engagement block 411 is provided on the button 41 to engage with the engagement position 212, and when the engagement block 411 is engaged in the engagement position 212, the sliding of the first telescopic arm is restricted.

[0041] In this embodiment, when the first telescopic arm is pulled to the fully extended position, the engagement block 411 of the button 41 is engaged in the engagement position 212, and the first telescopic rod 22 and the second telescopic rod 23 of the first telescopic arm are locked and cannot continue to slide, thus keeping it in a stable open position. When the button 41 is pressed, the engagement block 411 of the button 41 is disengaged from the engagement position 212 and the lock is released, and the first telescopic rod 22 and the second telescopic rod 23 of the first telescopic arm are released from the locked state, allowing the first telescopic arm to be adjusted to the closed position.

[0042] The number of engagement positions 212 may be one or more. In order to provide the telescopic legs with multiple stable open positions, multiple or multiple pairs of engagement positions 212 may be relatively installed along the longitudinal direction of the sliding edges 211 of the first telescopic rod 22 and the second telescopic rod 23 of the first telescopic arm. The locking position of the first telescopic arm can be adjusted by pressing the button 41, and the extension length can be adjusted to meet the needs of different application scenarios.

[0043] More specifically, as shown in FIGS. 12 and 13, the sliding edges 211 of the first telescopic rod 22 and the second telescopic rod 23 are provided with multiple pairs of teeth 2111 that correspond to each other along the longitudinal direction of the support handle 10, thereby forming multiple sets of engagement positions 212. Engagement blocks 411 are provided on both sides of the insertion end of the button 41, and when the two engagement blocks 411 are engaged with one pair of teeth 2111, the sliding of the first telescopic arm is restricted.
