In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0042] The utility model provides a support leg assembly, which can be applicable to supporting devices such as tripods, but is not limited here.

[0043] Reference Figures 1 to 5 In one embodiment of the utility model, the support leg assembly includes a support leg 100 and a support leg seat 200, one end of at least three support legs 100 are respectively arranged on the support leg seat 200 and can be switched between an extended position and a stored position, and during the switching process, the support legs 100 move in the same plane or curved surface; in the extended position, the other ends of at least three support legs 100 are away from each other; in the stored position, at least three support legs 100 are closed together.

[0044] In this embodiment, the number of support legs 100 is more than 3, preferably 3. One end of some support legs 100 can be rotatably set on the support base 200, or all support legs 100 can be set as a rotatable structure to achieve rotation switching between the deployed position and the stored position.

[0045] It should be noted that, in the storage position, the bottom surfaces of at least three supporting legs 100 are flush, that is, the three bottom surfaces are adjacent to each other to form a plane; or the bottom surfaces of at least three supporting legs 100 are adjacent to each other to form a curved surface, and the bottom surfaces of the supporting legs 100 are all curved structures. In other words, the supporting legs 100 of the present invention can adopt a regular rectangular parallelepiped structure, an arc-shaped rod structure, or an irregular special-shaped structure, which is not limited here.

[0046] It can be understood that the utility model arranges one end of the three supporting legs 100 on the foot seats 200 respectively and can be switched between the deployed position and the stored position, and the movement processes of storage and deployment are all in the same plane or curved surface. The foot assembly occupies less space in the height direction, reducing the overall volume of the foot assembly after storage, making it easier to store and organize, more convenient to carry, more convenient for users to use, reducing the packaging and transportation costs of the foot assembly, and the foot assembly is more beautiful after being stored as a whole.

[0047] like Figures 1 to 3 As shown, in one embodiment, the support base 200 includes a bottom shell 210, a cover plate 220 and a connecting column 230. The bottom shell 210 is arranged at the bottom of the support leg 100, the cover plate 220 is arranged at the top of the support leg 100 and can be fixed to the bottom shell 210 by snap connection, welding or gluing, etc., and the connecting column 230 is fixed to the cover plate 220 and is used to connect the bottom of the tie rod assembly 300 of the support device. In this way, the rotating ends of each support leg 100 can be conveniently connected, and the convenience of assembling the tie rod assembly 300 of the support device and the support base 200 is improved.

[0048] In this embodiment, the connecting column 230 may be provided with an external thread, and a threaded hole adapted thereto may be provided on the cover plate 220 to facilitate assembly. A decorative plate 221 may also be provided on the cover plate 220 to enhance the overall aesthetics of the support leg assembly.

[0049] In order to make the structure of the support leg assembly more compact and to minimize its storage volume, preferably, three support legs 100 are used. Figure 1 The supporting leg 100 is divided into a main supporting leg 111 and two auxiliary supporting legs 112. One end of the main supporting leg 111 is rotatably disposed on the bottom shell 210 or fixed on the bottom shell 210, and one end of the auxiliary supporting leg 112 is rotatably disposed on the bottom shell 210 and is respectively located on both sides of the main supporting leg 111. When in the storage position, the side surfaces of the auxiliary supporting legs 112 are respectively attached to the side surfaces of the main supporting leg 111.

[0050] To ensure that each support leg 100 is in a suitable position after being unfolded and to ensure the stability of its support, as Figure 1 As shown, in one embodiment, a limiting boss 211 is provided on the bottom shell 210, and when in the unfolded position, the side surfaces of the two auxiliary supporting legs 112 respectively abut against the two ends of the limiting boss 211 to limit the maximum unfolding angle of the two auxiliary supporting legs 112. Of course, in some other scenarios, two or more limiting structures can also be provided to respectively limit the rotation angle of the supporting leg 100.

[0051] Main references Figure 1 and Figure 2In one embodiment, the foot support 200 may further include a rotating disk 240, a mounting post 250 and a ball 260. The ball 260 is rollably disposed at the bottom of the mounting post 250 and is suitable for contacting the ground or a tabletop. The rotating disk 240 is rotatably sleeved on the outer circumference of the mounting post 250 and can be rotatably switched between a masking position and an exposed position. When in the masking position, the rotating disk 240 covers the ball 260, so that the rotating disk 240 can be used as a foot pad or the rotating disk 240 can be suspended in the air. When in the exposed position, the ball 260 is exposed, so that the ball 260 can be used as a walking ball. Such a configuration can save time and effort and greatly facilitate the use of the user.

[0052] In this embodiment, the ball bearing 260 may be a steel ball made of stainless steel or other materials, and a proper amount of lubricating oil may be applied to the ball bearing 260 to improve the smoothness of rolling.

[0053] For further information, please refer to Figures 6 to 9 The outer end of the support leg 100 may also be provided with a caster 50 for moving the support leg 100, and the caster 50 may be a universal wheel. This can further enhance the convenience of the movement of the support leg assembly, thereby making the support device more flexible.

[0054] In this embodiment, the outer periphery of the caster 50 may be provided with a wheel sleeve 60, which is rotatably disposed on the support leg 100 and can be rotatably switched between a first position and a second position; Fig. 9 As shown, in the first position, the wheel cover 60 covers the caster 50 so that the wheel cover 60 can be used as a foot pad; Figure 2 As shown, in the second position, the caster 50 is exposed outside the wheel cover 60, so that the caster 50 is used as a walking roller. In addition, the wheel cover 60 can also be used to adjust the support height of the support leg 100 to cater to uneven ground or tabletops, thereby greatly improving the applicability of the support leg assembly.

[0055] The utility model can be used as a foot pad by arranging a wheel cover 60 that can be manually rotated to adjust the height position, thereby ensuring the stability of the object supported by the support leg assembly and making the caster 50 exposed to achieve rapid movement.

[0056] Specifically, when in use, when it is necessary to move the supporting device having the supporting assembly, the wheel sleeve 60 can be rotated to expose the caster 50 and the caster 50 can be placed on the ground, and the rotating disk 240 can be adjusted to expose the ball 260 (in the scenario where the rotating disk 240 is not suspended), so that the ball 260 and the caster 50 cooperate to form a walking structure of the supporting device; when it is necessary to put the supporting device in a stable supporting state, the wheel sleeve 60 can be rotated in the opposite direction to lower it, so that the caster 50 is covered by the wheel sleeve 60. At this time, the bottom end of the wheel sleeve 60 touches the ground as a foot pad to maintain the stability of the entire supporting device and the objects thereon.

[0057] Please refer to Figures 3 to 6 In one embodiment, the support leg 100 includes an outer rod 10, an inner rod 20, a friction assembly 30 and an adjusting member 40; the inner rod 20 is telescopically arranged in the outer rod 10; the friction assembly 30 is arranged on one end of the inner rod 20 inserted into the outer rod 10 and abuts against the inner wall of the outer rod 10 to reduce the shaking amplitude of the inner rod 20 when it is telescopically extended; the adjusting member 40 is arranged on the friction assembly 30 to adjust the friction force between the friction assembly 30 and the inner wall of the outer rod 10.

[0058] In this embodiment, the outer rod 10 and the inner rod 20 can be in the shape of a round tube, a square tube, etc., which is not limited here.

[0059] The friction assembly 30 is a structure such as a friction block or sleeve whose position can be adjusted by the adjusting member 40. That is, the contact area and the extrusion force between the friction assembly 30 and the inner wall of the outer rod 10 are changed by changing the position, thereby adjusting the friction force between the friction assembly 30 and the inner wall of the outer rod 10. The specific structure of the friction assembly 30 and the adjusting member 40 is not limited here.

[0060] It can be understood that the utility model, by providing the friction assembly 30, helps to make the relative sliding friction resistance between the inner rod 20 and the outer rod 10 at an appropriate size, which can reduce the shaking amplitude of the inner rod 20 when it is extended and retracted, and the friction resistance can be adjusted by the adjustment member 40 during early assembly or later maintenance. In some application scenarios, the user can also adjust the friction resistance by himself, so as to improve the supporting stability of the tripod while meeting the requirements of different users for the telescopic feel.

[0061] Main reference Figure 6 In one embodiment, the friction assembly 30 may include a friction seat 31 and a plurality of steel balls 32. The friction seat 31 is disposed on the end of the inner rod 20 and is provided with a plurality of receiving holes. The plurality of steel balls 32 are received in the plurality of receiving holes one by one and abut against the inner wall of the outer rod 10. In this way, the smoothness of the inner rod 20 during extension and retraction can be improved, and the inner rod 20 can be kept to slide stably, extend and retract without shaking, and the support is more reliable.

[0062] In order to achieve the movement of the friction assembly 30 in the direction close to or away from the inner wall of the outer rod 10 to adjust the contact area between the steel ball 32 and the inner wall of the outer rod 10, further, mainly referring to Figure 6A friction block 21 that is in sliding contact with the inner wall of the outer rod 10 can be fixed on one end of the inner rod 20 inserted into the outer rod 10. The friction block 21 is provided with a groove, and the bottom of the groove is provided with an inclined surface. The friction seat 31 is arranged in the groove; a matching surface that matches the inclined surface is provided at the position of the friction seat 31 that contacts the inclined surface, or an adjusting inclined block 41 is provided between the friction seat 31 and the inclined surface of the friction block 21, and a contact surface that matches the inclined surface is provided at the position of the adjusting inclined block 41 that contacts the inclined surface; the adjusting member 40 connects the friction seat 31 and the friction block 21 and is used to adjust the relative position of the inclined surface and the matching surface or the contact surface to adjust the contact area between the steel ball 32 and the inner wall of the outer rod 10.

[0063] In this embodiment, the friction block 21 has two opposite surfaces, both of which are provided with grooves. The friction seat 31 includes a connecting arm connected to the friction block 21 through an adjusting member 40 and two mounting arms respectively connected to the two sides of the connecting arm. The two mounting arms are respectively arranged in two grooves and are both provided with accommodating holes.

[0064] The adjusting member 40 may be a manual adjusting member such as an adjusting bolt or an adjusting screw. Of course, an automatic adjusting mechanism may also be used to drive the friction seat 31 to move through a driving member such as a motor, which is not limited here.

[0065] Reference Figures 3 to 5 The utility model also proposes a supporting device, which includes a support leg assembly. The specific structure of the support leg assembly refers to the above embodiment. Since the supporting device proposed by the utility model includes all schemes of all embodiments of the above-mentioned support leg assembly, it has at least the same technical effect as the support leg assembly, which will not be elaborated here one by one.

[0066] In one embodiment, the support device may also include a rod assembly 300 and a support platform 400 disposed on the rod assembly 300 , the support platform 400 is used to connect objects such as a mobile phone or a camera, and one end of the rod assembly 300 away from the support platform 400 is fixed on the support base 200 .

[0067] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
