Description

Technical Field

[0001] The utility model belongs to the technical field of camouflage net supports, and particularly relates to a camouflage net support device with adjustable state and a camouflage obstacle avoidance device. Background Technique

[0002] In modern high-tech wars, battlefield detection means are becoming increasingly perfect, and targets are facing extremely severe battlefield survival environment conditions. Using a camouflage net as the most conventional anti-reconnaissance method, its support form greatly affects the camouflage effect. Therefore, the ability of the camouflage net support device to be adjusted according to local conditions when dealing with different terrains is becoming increasingly important.

[0003] The camouflage net support device is used to erect and support the camouflage obstacle surface, change the regular outer contour, and improve the camouflage effect of the obstacle. The support device provided by the prior art has a fixed length and cannot be adjusted. The top is generally an integral sheet structure and needs to be inserted at the top of the support rod for use, which is inconvenient to operate. Moreover, the state of the support device is relatively fixed, and the support height and the net spreading plate are not easy to adjust. With the improvement of the use requirements, a support rod with adjustable height appears, but it does not design the angle adjustment of the net spreading plate, and the designed serrated base is likely to affect the safety of personnel and equipment. The prior art provides a support device with adjustable height, but there are also defects such as the net spreading plate cannot be adjusted separately in angle and impurities are likely to enter the support rod body.

[0004] In the existing support device, the net spreading plate is fixed and cannot be adjusted in multiple levels, and it is not easy to change the shape of the camouflage net at the support position, which affects the camouflage effect. At the same time, the rods at all levels of height adjustment are not limited, and the thin rods are easy to be embedded in or separated from the thick rods. The base is serrated and easy to hurt people, and the base is not provided with an anti-blocking device, and snow, mud, etc. are likely to accumulate in the rod body, affecting the next use.

[0058] The camouflage net support device is used for erecting and supporting the camouflage screen surface, changing the regular contour, and enhancing the camouflage effect of the screen. However, in the existing support device, the net stretching plate is fixed and cannot be adjusted in multiple levels, making it difficult to change the shape of the camouflage net at the support position, which affects the camouflage effect. At the same time, the rods at each level of height adjustment are not limited, and the thin rods are easily inserted into or disengaged from the thick rods. The base is serrated and easy to hurt people, and the base is not equipped with an anti-blocking device, so snow, mud, etc. are easily accumulated in the rod body, affecting the next use.

[0059] To solve the above problems, the present utility model provides a camouflage net support device with adjustable states. The support height and the net stretching plate can be adjusted, it is convenient to use and applicable to various terrains.

[0060] In the first aspect, the present utility model provides a camouflage net support device with adjustable states. Refer to Figure 1 , which includes a support rod 10, a base 11, and a net stretching plate assembly 12; wherein, the support rod 10 is a support rod with adjustable length, and the bottom end of the support rod 10 is coaxially and detachably connected to the base 11;

[0061] Refer to Figure 2 , the net stretching plate assembly 12 includes a top cover 120, a plurality of net stretching plates 121, a switch 123, and a telescopic sleeve 122 is provided corresponding to each net stretching plate 121; wherein, the top cover 120 is coaxially and detachably connected to the top end of the support rod 10, and the plurality of net stretching plates 121 are circumferentially spaced apart along the top cover; each net stretching plate 121 is rotatably connected to the top cover 120; one end of each telescopic sleeve 122 is rotatably connected to the corresponding net stretching plate 121, and the other end of each telescopic sleeve 122 is rotatably connected to the base of the switch 123; the switch 123 can slide axially along the support rod 10 and can be fixed at the preset position after sliding to the preset position; each telescopic sleeve 122 is a telescopic sleeve with adjustable length.

[0062] As an example, one end of the telescopic sleeve is rotatably connected to the net stretching plate by a locking screw; the other end of the telescopic sleeve is rotatably connected to the base by a locking screw.
