[0032] The support clamping device and the support with the same according to the embodiments of the utility model will be described below with reference to Figures 1 to 9 .

[0033] According to the support clamping device of the first aspect embodiment of the utility model, the clamping piece 300 is used for clamping the external device, the rotating piece 200 is used for connecting with the main rod 100 outside, and the clamping piece 300 is rotatably connected with the rotating piece 200, forming the structure that the rotating piece 200 can rotate relative to the circumferential direction of the main rod 100.

[0034] For example Figure 2 , Figure 4 and Figure 5 As shown in the description of the utility model, the support clamping device includes rotating piece 200 and clamping piece 300, the rotating piece 200 is used for connecting with the top of the main rod 100, the clamping piece 300 is rotatably connected with the rotating piece 200, and the rotating piece 200 can drive the clamping piece 300 to rotate 360 degrees along the circumferential direction of the main rod 100.For example, the rotating piece 200 can be a bearing structure, the inner ring of the bearing is fixed with the top of the main rod 100, and the outer ring is connected with the clamping piece 300, so that the clamping piece 300 can rotate freely around the axis of the main rod 100.

[0035] The main rod 100 is a columnar structure for providing a support base. The support clamping device can be directly connected with the main rod 100 or indirectly connected with the main rod 100 through the holder 120. The circumferential direction of the main rod 100 is a direction along the cylindrical surface around the axis, that is, a direction around the outer side wall of the main rod 100.

[0036] According to the support clamping device provided in the embodiment of the utility model, the clamping piece 300 is used for clamping a mobile phone or a photographic equipment of a user, the clamping piece 300 is rotationally connected with the main rod 100 through the rotating piece 200, and the user can rotate the clamping piece 300 to rotate the shooting angle of the mobile phone or the photographic equipment, which greatly facilitates the user. The circumferential rotation function enables the clamping device to flexibly adapt to different shooting or fixing requirements. For example, the clamping device can be quickly turned during live broadcast, and the viewing angle can be adjusted around the main body during photography. When in use, the user only needs to rotate the clamping piece 300 to adjust the shooting direction of the equipment, without the need to move the main rod 100, so that the operation is convenient. The support clamping device is especially suitable for scenes requiring frequent change of the direction of the equipment, and the application range of the support is significantly expanded.

[0037] In some specific embodiments of the utility model, the clamping piece 300 comprises an upper clamping part 320, a lower clamping part 330 and an elastic telescopic piece, the two ends of the elastic telescopic piece are respectively connected with the upper clamping part 320 and the lower clamping part 330, and the lower clamping part 330 is rotationally connected with the rotating piece 200. When the upper clamping part 320 and the lower clamping part 330 move away from each other, the elastic telescopic piece is stretched.

[0038] For example Figure 2 and Figure 4 As shown in FIGS. 1, 2 and 3, the clamping piece 300 comprises an upper clamping part 320, a lower clamping part 330 and an elastic telescopic piece. The lower clamping part 330 is connected with the rotating piece 200, for example, fixed on the rotating disc 220 through a bolt.

For example, the elastic telescopic piece can be a spring 342, one end of the spring 342 is connected with the upper clamping part 320, and the other end is connected with the lower clamping part 330. When clamping the equipment, the upper clamping part 320 and the lower clamping part 330 are clamped to the equipment under the action of the spring 342. When the equipment needs to be taken out, an external force is applied to separate the upper clamping part 320 and the lower clamping part 330.

[0039] The arrangement of the elastic telescopic piece enables the clamping piece 300 to adapt to different sizes of equipment. Whether it is a relatively thin mobile phone or a slightly thicker photographic equipment, the elastic telescopic piece can be stretched or contracted to achieve firm clamping, thereby improving the versatility of the clamping device. At the same time, the elastic clamping mode can also reduce damage to the surface of the equipment.

[0040] In some specific embodiments of the utility model, the elastic telescopic piece includes connecting rod 341 and spring 342 which is sleeved on connecting rod 341, one end of connecting rod 341 is connected with lower clamping part 330 and / or upper clamping part 320, and the other end is elastically connected with upper clamping part 320 and / or lower clamping part 330 through spring 342.

[0041] For example Figure 4 And Figure 5 As shown in the figure, the elastic telescopic piece includes connecting rod 341 and spring 342 which is sleeved on connecting rod 341. Connecting rod 341 is provided with multiple, one end of some connecting rod 341 is connected with lower clamping part 330, and the other end is connected with upper clamping part 320 through spring 342, one end of some connecting rod 341 is connected with upper clamping part 320, and the other end is connected with lower clamping part 330 through spring 342. The arrangement of multiple connecting rod 341 not only ensures the stability of connection, but also makes the distance between upper clamping part 320 and lower clamping part 330 telescopic.

[0042] The specific elastic telescopic piece structure is simple, easy to process and assemble, connecting rod 341 can guide the moving direction of upper clamping part 320, ensure the stability of clamping process, and the elastic force provided by spring 342 can automatically adjust the clamping force according to the thickness of the equipment, which not only ensures the firmness of clamping, but also avoids the damage to the equipment caused by excessive clamping force, improves the practicability and reliability of the clamping device.

[0043] In some specific embodiments of the utility model, rotating piece 200 includes bottom disc 210 and rotating disc 220, bottom disc 210 is used for being connected with main rod 100, rotating disc 220 is rotationally connected with bottom disc 210, clamping piece 300 is connected with rotating disc 220, forming the structure that rotates together with rotating disc 220 relative to bottom disc 210.

[0044] For example Figure 5 And Figure 6 As shown in the figure, rotating piece 200 includes bottom disc 210 and rotating disc 220, bottom disc 210 is connected with main rod 100, and can be fixed on the top of main rod 100 through bolts. Rotating disc 220 is rotationally connected with bottom disc 210, so that rotating disc 220 can rotate flexibly relative to bottom disc 210, and clamping piece 300 is connected with rotating disc 220, and can rotate together with rotating disc 220 along the circumference of bottom disc 210.

[0045] The rotating piece 200 is decomposed into the bottom disc 210 and the rotating disc 220, the bottom disc 210 is stably connected with the main rod 100, and the rotating disc 220 realizes the rotating function, and the structure design makes the rotating process more stable and smooth, can bear certain load, ensures the stability of the clamping piece 300 when rotating, enhances the rotating stability, avoids the shaking of the clamping piece 300, and ensures the stability when fixing the equipment.

[0046] In some embodiments of the utility model, the top surface of the chassis 210 is circumferentially provided with a plurality of limiting grooves 211, the lower clamping part 330 is provided with a plurality of positioning rods 310 matched with the shape of the limiting grooves 211, and the positioning rods 311 are inserted into the limiting grooves 211.

[0047] For example, as shown in Figure 6 , Figure 7 and Figure 9 , the top surface of the chassis 210 is circumferentially provided with a plurality of limiting grooves 211, which can be evenly distributed on the circumference of the chassis 210. The bottom of the clamping part 300 is provided with a plurality of positioning rods 310 matched with the shape of the limiting grooves 211, and the number of positioning rods 310 can be one or more, for example, two positioning rods 310 are provided. The bottom of the positioning rod 310 is inserted into the limiting groove 211, and when the clamping part 300 rotates relative to the chassis 210, the positioning rod 310 will move from one limiting groove 211 to the next limiting groove 211.

[0048] The cooperation of the limiting groove 211 and the positioning rod 310 can position the rotating position of the clamping part 300, and when the device is adjusted to the appropriate angle, the positioning rod 310 is inserted into the limiting groove 211 to prevent the clamping part 300 from rotating freely, ensuring the stability of the device during use. When rotating, the user needs to exert a certain force to make the positioning rod 310 disengage from the limiting groove 211, which is convenient to operate and can ensure accurate positioning.

[0049] Further, the limiting groove 211 and the bottom of the positioning rod 310 are matched with the shape of the hemisphere.

[0050] For example, as shown in Figure 7 and Figure 9 , the limiting groove 211 and the bottom of the positioning rod 310 are matched with the shape of the hemisphere. That is, the bottom of the limiting groove 211 is a hemispherical concave surface, and the bottom of the positioning rod 310 is a hemispherical convex surface, which cooperate with each other.

[0051] The design of the ball makes the positioning rod 310 rotate more flexibly in the limiting groove 211, and when the angle needs to be adjusted, the positioning rod 310 can easily slide from one limiting groove 211 to another limiting groove 211, reducing the frictional resistance in the rotating process. At the same time, the hemispherical structure can also provide a certain positioning force to ensure the stability of the clamping part 300 in the non-rotating state, realizing a good combination of rotating flexibility and positioning stability.

[0052] In some specific embodiments of the utility model, the rotating disc 220 is arranged between the base disc 210 and the clamping piece 300, the rotating disc 220 is provided with a through hole 221, and the positioning rod 310 passes through the through hole 221 and is inserted into the limiting groove 211.

[0053] For example Figure 5 、 Figure 6 and Figure 8 The rotating disc 220 is arranged between the base disc 210 and the clamping piece 300, the rotating disc 220 is provided with a through hole 221, and the positioning rod 310 at the bottom of the clamping piece 300 passes through the through hole 221 and is inserted into the limiting groove 211 of the base disc 210.

[0054] The rotating disc 220 is arranged between the base disc 210 and the clamping piece 300, the rotating disc 220 is provided with a through hole 221, and the positioning rod 310 at the bottom of the clamping piece 300 passes through the through hole 221 and is inserted into the limiting groove 211 of the base disc 210.

[0055] In some specific embodiments of the utility model, the clamping piece 300 rotates relative to the base disc 210 by at least 360 degrees.

[0056] The clamping piece 300 rotates relative to the base disc 210 by at least 360 degrees, realizing flexible rotation adjustment in multiple dimensions, and the structure is stable and reliable.

[0057] According to the support of the second aspect of the utility model, the support includes a support leg 400, a main rod 100 and the support clamping device of the first aspect of the utility model, one end of the support leg 400 is rotatably connected with the main rod 100, and the main rod 100 is connected with the rotating part 200.

[0060] For example Figure 2 and Figure 3As shown, the rotating member 200 is rotationally connected with the main rod 100, and the rotating shaft direction is the radial direction of the main rod 100. That is, the rotating member 200 can not only rotate along the circumferential direction of the main rod 100, but also rotate in the radial direction of the main rod 100, so as to realize the adjustment of the pitch angle. For example, a horizontal rotating shaft is arranged at the top of the main rod 100, and the rotating member 200 is connected with the main rod 100 through the rotating shaft, so that the rotating member 200 can rotate up and down around the horizontal rotating shaft.

[0061] The rotating shaft direction is the radial direction of the main rod 100, so that the rotating member 200 has the function of rotating in the radial direction, thereby enabling the clamping member 300 to adjust the pitch angle, increasing the angle adjustment dimension of the support clamping device, and enabling the user to adjust the orientation of the equipment in the circumferential and radial directions according to actual needs, thereby further improving the flexibility and applicability of the device and meeting the use requirements in more complex scenes.

[0062] In some specific embodiments of the present application, the top of the main rod 100 is provided with a holder 120 with a rotating hole 111 in the radial direction, and the bottom of the rotating member 200 is provided with a coaxial rotating hole 111 matched with the holder 120, and the rotating holes 111 are hingedly connected with each other.

[0064] The hinged connection mode of the rotating hole 111 is simple in structure and stable in connection, and can ensure the rotating flexibility of the rotating member 200 in the radial direction, and the arrangement of the pin shaft also facilitates the installation and disassembly of the rotating member 200. When the pitch angle needs to be adjusted, the rotating member 200 can easily rotate around the pin shaft, meeting the needs of users for different pitch angles.

[0065] Further, the top of the main rod 100 and the bottom of the rotating member 200 are sequentially provided with a plurality of rotating parts 110 inserted with each other in the radial direction of the main rod 100, and the rotating hole 111 is coaxially arranged on the rotating part 110.

The rotating part 110 can be a protrusion provided on the top of the main rod 100 and a groove provided on the bottom of the rotating piece 200, or vice versa, the protrusion and the groove are inserted into each other to form a stable connection structure. The rotating hole 111 is coaxially arranged on the rotating part 110, that is, the rotating hole 111 on each rotating part 110 is on the same axis, and the hinge is realized by passing the pin shaft through the rotating holes 111.

[0067] The plurality of rotating parts 110 which are inserted into each other increase the contact area between the main rod 100 and the rotating piece 200, improve the stability and structural strength of the connection, and can withstand greater load, while the coaxial arrangement of the rotating hole 111 ensures the smoothness of rotation, makes the rotation of the rotating piece 200 in the radial direction more stable, reduces the shaking in the rotation process, and improves the reliability and durability of the whole support clamping device.
