Embodiment 1

[0031] refer to Figure 1 to Figure 7 , the embodiment of the present invention provides an automatic locking and fastening device for leg tubes, including a guide switch 3 and a guide slant column 6, such as Figure 4 As shown, the guide switch 3 is a hollow cylinder lacking a bottom surface, and the guide slant column 6 is a circular platform shape, and the guide nail 4 is installed on the inner bottom surface of the guide switch 3, and the lower end surface of the guide nail 4 is a spherical surface. There is a guide groove 61 suitable for the guide nail 4, the guide groove 61 is provided with a continuous gradient from deep to shallow, the guide nail 4 and the guide groove 6 constitute a set of transmission mechanism, when the guide nail 4 slides along the guide groove 61, the guide nail 4 The horizontal position of the lower end surface can move up and down, that is, when the guide nail 4 moves relatively along the guide groove 61 , the guide switch 3 can move up and down...

Embodiment 2

[0041] This embodiment differs from Embodiment 1 in that, as Figure 5 As shown, the guide groove 61 in Embodiment 1 is canceled, the upper surface of the guide inclined column 6 is provided with a guide slope 62, and the inner bottom surface of the guide switch 3 is provided with a mating surface 63 that conflicts with the guide slope 62, and the guide slope 62 and the mating surface 63 That is to constitute a set of transmission mechanism, when the slant guide column 6 and the guide switch 3 rotate mutually, the mating surface 63 can move up and down along the guide slope 62, so that the guide switch 3 can move up and down along the column slope of the guide slant column 6.

[0042] Using the automatic locking and fastening device for leg tubes provided by the embodiments of the present invention, for photography tripods, monopods and crutches, etc., which are composed of multi-section tubes, grasping one section of tube can quickly switch between the loose and locked state, ...

Abstract

The invention provides a leg tube automatic locking device which comprises a guide switch and a guide inclined column which is matched with the guide switch for use, wherein the guide switch is a hollow cylinder without the bottom surface, the guide inclined column is in a circular truncated cone shape, through holes are evenly formed in the side surface of the guide switch, and the through holes are provided with locking shafts in a matched mode. A transmission mechanism is arranged between the guide switch and the guide inclined column, so that when the guide switch and the guide inclined column rotate mutually, the guide switch vertically moves along the inclined cylinder surface of the guide inclined column and drives the locking shafts to move along the guide inclined column. The invention further provides a photography tripod, a unipod and a crutch. According to the leg tube automatic locking device, the photography tripod, the unipod and the crutch, using convenience is achieved, locking force is enhanced, leg tubes can be rapidly regulated to be loosened and locked, loosening and locking can be regulated in a single-section or integral mode, and automatic locking at any position can be conducted in a locking state.

Description

technical field [0001] The invention relates to an automatic locking and fastening device for leg tubes, a photographic tripod, a monopod and a crutch. Background technique [0002] It is inevitable to encounter shaking when taking pictures or videos in daily life. A photography tripod can provide support for the photographer and is an essential photographic equipment for taking good photos. Because the leg tubes of tripods are generally long and inconvenient to carry, there are many tripods with retractable fastening design for the leg tubes on the market. The length of the leg tubes can be adjusted according to the photographer's needs to adjust the height of the tripod. [0003] The inventor found that the existing technology has the following disadvantages: the adjustment of the length of the leg usually requires external fastening parts to fasten, which is inconvenient to adjust the length of the leg, and the locking force is limited. Buckle squeeze lock. Contents of...
