Problems solved by technology

[0002] In order to prop up the mesh surface of the camouflage net, a net tensioner is usually installed on the top of the support rod. The current net tensioner is generally a whole piece structure, which is used by plugging in the top of the support rod through a jack; this kind of net tensioner is rigid. Large, small elasticity, easy to break after propping up the camouflage net, and easy to damage the camouflage net

Embodiment Construction

[0010] combine figure 1 and figure 2 As shown, the present invention provides a spiral net tensioner, including a fixed column 1 and a support bar 2, the support bar 2 is in the shape of a spiral line, the center of the bottom of the support bar 2 is provided with an installation hole 2a, and the support bar 2 passes through the installation hole 2a Connected with the top of the fixed column 1, the outer end of the support bar 2 is provided with a ring 3, and the second circle of the support bar 2 from the outside to the inside is formed to cooperate with the ring 3; Mating socket 1a.

[0011] The support bar 2 in the shape of a spiral is used as the main body of the camouflage net. Under the pressure of the camouflage net, the support bar 2 deforms downward, which can support the camouflage net and is not easy to break and damage; the ring 3 On the one hand, it plays the role of closing the support bar 2 to prevent the net from hanging; on the other hand, the ring 3 can sl...

Abstract

The invention discloses a spiral net unfolding device. The spiral net unfolding device comprises a fixing column and a supporting strip. The supporting strip is in a spiral line shape. An installation hole is formed in the center of the bottom of the supporting strip. The supporting strip is connected with the top end of the fixing column through the installation hole. A circular ring is arranged at the outer end of the supporting strip. The supporting strip is matched with the circular ring through a second circle from outside to inside. An insertion hole is formed in the bottom of the fixing column, and a supporting rod is inserted into the insertion hole in a matched mode. The supporting strip which is in the spiral line shape is used as a main body for supporting a camouflage net and deforms downwards under the pressure of the camouflage net so that the camouflage net can be supported, and the camouflage net is not prone to breakage or damage; on one hand, the circular ring is used for closing the supporting strip, so that the camouflage net is prevented from being hooked; and on the other hand, the circular ring can slide freely along the second circle of the supporting strip from outside to inside, so that the effect that the supporting strip can reliably deform and restore on the premise that the outer end is sealed is guaranteed.

Description

technical field [0001] The invention relates to the technical field of camouflage, in particular to a spiral net tensioner. Background technique [0002] In order to prop up the mesh surface of the camouflage net, a net tensioner is usually installed on the top of the support rod. The current net tensioner is generally a whole piece structure, which is used by plugging in the top of the support rod through a jack; this kind of net tensioner is rigid. Large and small in elasticity, it is easy to break after propping up the camouflage net, and it is also easy to damage the camouflage net. Contents of the invention [0003] The object of the present invention is to provide a spiral net tensioner, which has a certain degree of elasticity, can be deformed with external pressure, is not easy to be damaged, and can avoid the phenomenon of hanging nets between the camouflage net and will not Causes damage to camouflage nets. [0004] The technical solution adopted by the present...
