DETAILED DESCRIPTION

[0034] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The detailed description of the following embodiments and the accompanying drawings are used to exemplarily illustrate the principles of the present invention, but cannot be used to limit the scope of the present invention, that is, the present invention is not limited to the described embodiments, and covers any modification, replacement and improvement of parts, components and connection modes without departing from the spirit of the present invention.

[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] According to a first aspect of an embodiment of the present invention, a photography and video platform clamping seat with a double-sided clamping member is provided, such as Figure 1-2 As shown, the first aspect of the present invention provides a photography and video head clamp with a double-sided clamp, comprising a clamp body 1, a first movable clamp 2, a second movable clamp 3, a first locking knob 4, a second locking knob 5, a first connecting rod 6 and a second connecting rod 7;

[0037] The first movable clamp 2 and the second movable clamp 3 are respectively arranged at two ends of the clamp base body 1, and the first locking knob 4 and the second locking knob 5 are arranged on the same side of the clamp base body 1 and are arranged in sections along the same axis;

[0038] The second connecting rod 7 is connected to the clamp seat body 1, the first connecting rod 6 is passed through the second connecting rod 7 and connected to the first movable clamp 2, one end of the first connecting rod 6 is connected to the first locking knob 4, and the second locking knob 5 is sleeved on the second connecting rod 7 and is used to move the second movable clamp 3 axially.

[0039] In the above embodiment, the second connecting rod 7 can be fixedly connected to the clamp seat body 1, or can be a structural form integrally formed with the clamp seat body 1, or can be threadedly connected; in addition, there is no specific limitation on the length of the second connecting rod 7, and it can be longer than the clamp seat body 1 or shorter than the clamp seat body 1.

[0040] Specifically, when the length of the second connecting rod 7 is greater than the clamping seat body 1, the first connecting rod 6 is inserted into the second connecting rod 7, and the second connecting rod 7 penetrates the clamping seat body 1;

[0041] When the length of the second connecting rod 7 is smaller than the clamping seat body 1 , the first connecting rod 6 is sequentially inserted through the second connecting rod 7 and the clamping seat body 1 .

[0042] At the same time, the first connecting rod 6 can be moved or rotated while being driven by the first locking knob 4 .

[0043] Optionally, the second movable clamp 3 is disposed between the second locking knob 5 and the clamp seat body 1, and the second connecting rod 7 is passed through the second movable clamp 3. Specifically, an elastic element (not shown in the figure, specifically a spring) is disposed between the second movable clamp 3 and the clamp seat body 1, and when the second locking knob 5 is turned, the second movable clamp 3 is driven to move toward the clamp seat body 1 accordingly; when the second locking knob 5 is turned in the opposite direction, the second movable clamp 3 will move away from the clamp seat body 1 under the thrust generated by the elastic deformation of the spring.

[0044] Optionally, an elastic element (not shown in the figure, specifically a spring) is provided between the first movable clamp 2 and the clamp seat body 1. When the first locking knob 4 is rotated, the first movable clamp 2 is driven to move toward the clamp seat body 1 accordingly; when the first locking knob 4 is rotated in the opposite direction, the first movable clamp 2 will move away from the clamp seat body 1 under the thrust generated by the elastic deformation of the spring.

[0045] In some optional embodiments, one end of the first connecting rod 6 is threadedly connected to the first locking knob 4, and the other end of the first connecting rod 6 is fixedly connected to the first movable clamp 2; or,

[0046] One end of the first connecting rod 6 is fixedly connected to the first locking knob 4 , and the other end of the first connecting rod 6 is threadedly connected to the first movable clamp 6 .

[0047] In some optional embodiments, one end of the second connecting rod 7 is fixedly connected to the clamping seat body 1, and the other end of the second connecting rod 7 is threadedly connected to the second locking knob 5; or,

[0048] One end of the second connecting rod 7 is threadedly connected to the clamp seat body 1 , and the other end of the second connecting rod 7 is fixedly connected to the second locking knob 5 .

[0049] In the above embodiment, the first locking knob 4 and the second locking knob 5 of the photography and video head clamp with a double-sided clamp can be respectively screwed through the corresponding outer shaft 6 and inner shaft 7, and will not hinder the locking operation of the first movable clamp 2 and the second movable clamp 3.

[0050] According to a second aspect of an embodiment of the present invention, a photography and videography platform is provided, such as Figure 3-5As shown, it includes the above-mentioned photography and video head clamp base with double-sided clamps and a driving body, and the driving body is provided with a guide rail 804 that is compatible with the shape of the first movable clamp 2 or the second movable clamp 3; the clamp base body 1 is slidably connected to the driving body.

[0051] Specifically, Figure 3 As shown, the guide rail 804 can be set as a dovetail rail to enable the first movable clamping member 2 and the second movable clamping member 3 to slide along the driving body.

[0052] The driving body 8 can be fixed to other brackets below the first movable clamp 2 and the second movable clamp 3 , or can be fixed to the equipment above the first movable clamp 2 and the second movable clamp 3 .

[0053] In some optional embodiments, such as Figure 3-5 As shown, the driving body includes a first crank 801, a second crank 802 and a transmission mechanism. The first crank 801 and the second crank 802 are respectively fixed at two ends of the transmission mechanism, and the fixed positions of the first crank 801 and the second crank 802 differ by 180°; the transmission mechanism is used to drive the clamping base body 1 to slide under the action of the first crank 801 and the second crank 802.

[0054] In the above embodiment, the specific structure of the transmission mechanism is not limited, as long as the first crank 801 and the second crank 802 can be used to drive the clamping seat body 1 to translate. Regardless of whether the transmission structure adopts a screw structure, a gear-rack structure, a chain-gear structure, or a belt-pulley structure, this method can be used to achieve stable and sustainable sliding.

[0055] When one of the handles moves up, the other handle moves down, which not only makes the operator's force more even, but also makes the force of the entire supporting system including the tripod more balanced, thereby making the shooting equipment run more smoothly.

[0056] Specifically, the rotation axes of the first crank 801 and the second crank 802 are on the same straight line (ie, coaxially arranged). Such an arrangement can make the forces applied by the two cranks more balanced.

[0057] In some optional embodiments, such as Figure 4-5 As shown, the transmission mechanism is a screw rod 803 , and the clamping seat body 1 is provided with a screw sleeve 101 matched with the screw rod 803 , which is used to realize the sliding connection between the driving body and the clamping seat body 1 .

[0058] The above embodiment provides another specific form of the transmission mechanism. Through the mutual cooperation between the screw 103 and the screw sleeve 102, the first crank handle 801 and the second crank handle 802 at both ends of the screw 803 are respectively shaken to drive the screw 803 to rotate, thereby driving the screw sleeve 101 sleeved on the screw 803 to move, and finally realizing the sliding of the functional body 2.

[0059] In some optional embodiments, such as Figure 4-5 As shown, the screw sleeve 101 has an incomplete thread. Such a setting is intended to avoid fluctuations in a direction perpendicular to the direction of movement due to machining errors during the movement.

[0060] According to a second aspect of an embodiment of the present invention, another photography and videography platform is provided, Figure 6 As shown, it includes the above-mentioned photography and video head clamp base with double-sided clamps and a guide rail body 9. The clamp base body 1 is provided with a handle 10 and a transmission mechanism. The handle 10 is used to drive the transmission mechanism to realize the movement of the clamp base body 1 relative to the guide rail body 9.

[0061] In some optional embodiments, the transmission mechanism is a gear 102 , and the guide rail body 9 is provided with a rack 901 that matches the gear 102 , so as to realize the sliding connection between the guide rail body 9 and the clamp seat body 1 .

[0062] In some optional embodiments, the rack 901 is arranged along the length direction of the clamp seat body 1 , and the gear 102 is meshed with the rack 901 .

[0063] The above embodiment provides a second specific form of the transmission mechanism, in which the transmission mechanism and the clamp seat body 1 are set as an integrated structure. Through the mutual cooperation between the gear 102 and the rack 901, one or two handles 10 set at the end of the gear 102 are used to drive the gear 102 to move on the rack 901 that is meshed with it, and finally realize the relative sliding of the functional clamp seat body 1 on the guide rail body 9.

[0064] In some optional embodiments, the clamping seat body 1 is further provided with any one of a dovetail track, a clamping seat or a screw hole, wherein the dovetail track, the clamping seat or the screw hole is used to clamp other equipment or be clamped by other equipment.

The present invention is not limited to the specific steps and structures described above and shown in the figures. In addition, for the sake of brevity, a detailed description of known methods and technologies is omitted here.

[0066] The above are only embodiments of the present application and are not limited to the present application. For those skilled in the art, the present application may have various changes and variations without departing from the scope of the present invention. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
