Problems solved by technology

[0008] 5. It is inconvenient to open the angle of the above-mentioned tripod. It is almost necessary to open the telescopic tubes of each group separately.
[0009] 6. Almost none of the above-mentioned tripods can be simultaneously and quickly opened at any angle within the range of normal use
[0010] 7. The locking of the telescopic tube of the above-mentioned tripod is easy to loosen, and as long as one of the telescopic tubes is loose, it can cause the tripod to be unstable, easy to fall over, and even the equipment on the tripod may be broken
In addition, the weight of the above-mentioned tripod support equipment is also very limited
[0011] 8. The above-mentioned tripod cannot be quickly and synchronously self-locked and fixed after being folded
[0012] 9. The plane stability of the above-mentioned tripod is not enough when it is opened, and it is easy to fall in a certain direction during operation
Also, for example: at the press conference, many reporters will use a tripod camera. Due to the limitation of the size of the venue and the concentration of the front, the tripod cannot be opened larger, otherwise it will not only affect others but also reduce the height. Will affect the stability of the tripod

Embodiment 1

[0057] Embodiment 1: (Tetrapod structure)

[0058] combine Figure 1-11 As shown, take the quadruped as an example: it includes an outer tube 6, an inner tube, a telescopic lock device 8 and a connecting sleeve 9; 6 is also the thickest pipe on the top, the inner pipe includes the lower inner pipe 18 and the upper inner pipe 19, the upper inner pipe 19 is socketed inside the outer pipe 6, the lower inner pipe 18 is socketed inside the upper inner pipe 19, and the upper inner pipe 19 is socketed inside the upper inner pipe 19. The upper part of the pipe 19 and the lower inner pipe 18 is provided with a telescopic lock device 8, and the connecting sleeve 9 is connected to the upper end of the outer pipe 6, and four groups of three-section telescopic pipes are respectively formed; it also includes the main joint 11 and the middle telescopic pipe 16, The connecting sleeve 9 is hinged with the main joint 11, the main joint 11 is sleeved with the middle pipe 13, and the main joint ...

Embodiment 2

[0075] Embodiment 2: (tripod structure)

[0076] The principle is basically the same, the structure difference between the tripod and the tetrapod is not big, combined Figure 12 As shown, on the basis of Embodiment 1, all that is related to the tetrapod is changed to be related to the tripod. Others are basically the same as in Embodiment 1, and will not be repeated here.

Embodiment 3

[0077] Embodiment 3: (another structure of quadruped and tripod telescopic tube)

[0078] On the basis of Embodiment 1, it is changed to: the connecting sleeve 9 is connected to the inner pipe, that is, the thinnest pipe is on the top, and the pull wire 113 is changed to a pressed iron wire or a carbon fiber rod directly pressed against the telescopic lock device 8. This structure is more for simplicity. Others are basically the same as in Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a quadripod or tripod capable of achieving rapid extending, retracting and positioning and convenient to unfold, and belongs to lifting supporting devices. The quadripod or tripod capable of achieving rapid extending, retracting and positioning and convenient to unfold comprises at least three telescopic pipes, wherein each telescopic pipe is composed of an outer pipe, at least one section of inner pipe, at least one extension-retraction lock device and a connecting sleeve. The quadripod or tripod further comprises a main connecting piece and a middle pipe or a middle telescopic pipe. Each connecting sleeve is hinged to the main connecting piece and is connected with the corresponding outer pipe or the inner pipe. The main connecting piece is connected with the middle pipe in a sleeving manner, the main connecting piece or the middle pipe is connected with a pressing piece in a sleeving manner, and a pressing travel space is reserved between the pressing piece and the main connecting piece. Compared with a common tripod, the tripod capable of achieving rapid extending, retracting and positioning and convenient to unfold achieves that when the tripod is unfolded or the telescopic pipes are retracted, repeated unlocking and locking are not needed, a user does not need to bend down and does not need to worry that the tripod possibly topple; the telescopic pipes of the tripod can quickly extend out and be automatically positioned and can quickly retract and be automatically limited, and on the basis, the quadripod with higher stability than the tripod ona plane is realized; and meanwhile, the requirement for use experience feeling of people is met.

Description

technical field [0001] The invention belongs to a lifting support device, and more specifically relates to a four-legged or tripod that can be quickly telescopically positioned and easily opened. Background technique [0002] At present, almost all the tripods on the market are equipped with several telescopic tubes (leg tubes) to expand and contract. It has the characteristics of small size, easy to carry, and convenient to use as a set. It is widely used in various fields and has become a must-have for most people. One of the supplies. Common tripod-supported equipment such as: cameras, measuring instruments, cameras, projectors, displays, astronomical mirrors, cameras, microphones, lighting, audio, display and live broadcasts, and other objects that need to be supported. [0003] Yet above-mentioned existing product or the tripod in the prior art, it has some weak points or exists some serious shortcoming for a long time: [0004] 1. The telescopic tubes of the above-me...
