Description

Technical Field

[0001] This application relates to the field of photographic light stands, and more particularly, to a photographic light stand with high stability. Background Art

[0002] Skillful photography often relies on the help of a tripod. For example, in night scene photography, macro photography, etc., the main function of the tripod is to stabilize the camera to achieve certain photographic effects. The most common is to use a tripod in long exposure. When a user wants to take a night scene or a picture with a flowing track, the exposure time needs to be increased. At this time, the digital camera cannot shake, and the help of a tripod is required.

[0003] Photographic light stands are used in photography, but the existing photographic light stands do not have a structure with high stability. When the camera shakes during shooting, it cannot be stably shock-absorbed, resulting in an unsatisfactory video, which is not convenient for users to use and reduces the practicality of the photographic light stand.

[0050] The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0051] Refer to Figures 1-5, A photographic light stand with high stability, comprising a support 1, a placement table 2, legs 3, and a clamping device 4; the placement table 2 is arranged on the support 1 for placing a camera, there are three legs 3, one end of each is hinged to the long end of the support 1 respectively, and the other end is hinged to the lower end of the support 1 through a connecting ring 5, the connecting ring 5 is movably sleeved on the support 1, and there are two clamping devices 4 which are symmetrically arranged on the placement table 2 for clamping and fixing the camera. Among them, a fixed cylinder 6 is fixedly arranged at the bottom of the support 1, the interiors of the fixed cylinder 6 and the support 1 are both hollow and communicate with each other, a support rod 7 is arranged through the support 1, and both ends of the support rod 7 are fixedly connected to the connecting ring 5 and can drive the movement of the support rod 7 as the connecting ring 5 moves up and down. A long slot 8 for the up and down movement of the support rod 7 is opened on the support 1, and a stabilizing member is arranged on the support rod 7, and one end of the stabilizing member passes through outside the fixed cylinder 6 and abuts against the ground. When the three legs 3 move outwards respectively, the connecting ring 5 is driven to move from the upper end of the support 1 to the lower end of the support 1 by means of hinge, the connecting ring 5 drives the support rod 7 to move together, the support rod 7 drives the stabilizing member to move downwards, so that the stabilizing member extends out of the fixed cylinder 6 and contacts the ground, thereby improving the stability of the placement of the photographic light stand.

[0052] The stabilizing member includes a connecting rod 9 and a first friction pad 10; the connecting rod 9 is fixedly arranged on the support rod 7, and the first friction pad 10 is fixedly arranged on the connecting rod 9. Under the action of the first friction pad 10, the friction with the ground is increased, and thus the stability of the placement of the photographic light stand is improved.

[0053] First elastic protrusions 11 are arranged at both ends of the first friction pad 10, and second elastic protrusions 12 matched with the first elastic protrusions 11 are arranged on the inner wall of the fixed cylinder 6, and the length of the second elastic protrusions 12 is greater than that of the first elastic protrusions 11. Among them, the opposite surfaces of the first elastic protrusions 11 and the second elastic protrusions 12 are both inclined. When the first friction pad 10 moves from top to bottom and contacts the ground, the first elastic protrusions 11 will squeeze the second elastic protrusions 12, causing the first elastic protrusions 11 and the second elastic protrusions 12 to deform simultaneously until the first elastic protrusions 11 move to the bottom of the second elastic protrusions 12. And because the length of the second elastic protrusions 12 is greater than that of the first elastic protrusions 11, the second elastic protrusions 12 play a limiting role on the first elastic protrusions 11, and at the same time, the bottom surface of the second elastic protrusions 12 is closely attached to the top surface of the first elastic protrusions 11, and the second elastic protrusions 12 play a squeezing role on the first elastic protrusions 11. Thereby ensuring the degree of fit between the first friction pad 10 and the ground and maintaining the friction force.

[0054] The clamping device 4 includes a fixed block 13, a clamping plate 14, and a first spring 15; the fixed block 13 is fixedly arranged on the placement table 2, the clamping plate 14 is movably arranged on the placement table 2, one end of the first spring 15 is connected to the fixed block 13, and the other end is connected to the clamping plate 14; a sliding groove 16 for the clamping plate 14 to move is formed on the placement table 2, and a cavity 17 for installing the first spring 15 is formed in the fixed block 13.

[0055] In order to facilitate the angle adjustment of the fixed camera, the present application further includes a rotating device. The rotating device includes a fixed disk 18 and a rotating disk 19; the fixed disk 18 is fixedly arranged on the bracket 1, the rotating disk 19 is fixedly arranged at the bottom of the placement table 2 and is rotationally matched with the fixed disk 18. Specifically, a groove body 20 is formed on the rotating disk 19, a key 21 is installed in the groove body 20, one end of the key 21 extends outside the groove body 20, a second spring 22 is arranged between the inner wall of the groove body 20 and the key 21, a clamping block 23 is arranged at one end of the key 21, an annular groove 24 is formed on the fixed disk 18, one end of the key 21 is inserted into the annular groove 24, and a plurality of card slots 25 communicated with the annular groove 24 are formed on the fixed disk 18. One end of the clamping block 23 is clamped into the card slot 25. When the camera angle needs to be adjusted, press the key 21, and under the action of the second spring 22, the key 21 moves into the groove body 20, so that the key 21 drives the clamping block 23 to disengage from the card slot 25, and then rotate the rotating disk 19 to make the key 21 move along the annular track of the annular groove 24 until the camera angle is adjusted, and then release the key 21 to make the key 21 drive the clamping block 23 to be inserted into the card slot 25 again.

[0056] A limiting ring 26 is arranged on the rotating disk 19, and a limiting groove 27 for the limiting ring 26 to be inserted is formed on the fixed disk 18.

[0057] A notch 28 for placing the camera is formed on the placement table 2.

[0058] The bracket 1 includes a first support rod 29, a second support rod 30, and a fixing pin 31; the second support rod 30 is movably inserted into the first support rod 29, a plurality of first through holes 32 for the fixing pin 31 to be inserted are formed on the second support rod 30, and a second through hole for the fixing pin 31 to be inserted is formed on the first support rod 29. The fixing pin 31 is inserted into the first through hole 32 and the second through hole at the same time to fix the second support rod 30 on the first support rod 29.

[0059] A second friction pad 33 is arranged on the leg 3, and a damper 34 is installed between the second friction pad 33 and the leg 3.
