Abstract
The invention relates to a retraction device for a shielding net, which comprises a spindle, a transmission chain wheel, a shaft support, a guide rail fixing base and the shielding net, wherein a guide rail is respectively arranged at two sides of the shielding net; the spindle is arranged on the upper end of the guide rail; the transmission chain wheel is arranged on one end of the spindle; the other end of the spindle is fixed on the guide rail through the shaft support; the shielding net is arranged on the spindle; and a plurality of sliding blocks are arranged at two sides of the shielding net. The sliding blocks can slide up and down in the guide rail arranged at two sides of the shielding net, so as to hide important targets and protect the slide blocks. The retraction device provided by the invention has the advantages of simple structure, and high reliability, and is convenient to operate.
Description
Technical field:
The present invention relates to a kind of radiation proof usefulness, can apply to the gauze screen that uses on the hidden apparatus, relate in particular to the gauze screen draw off gear.
Background technology:
At present; go up the needs of maintaining secrecy for some are military; usually use some camouflage nets; protect some military important goals; but these devices can play the effect of some protections for some scoutings; and afield, if the enemy uses radar scanning, these camouflages have not just had the effect of protection.And,, also can cause certain injury to people's health if do not adopt some shieldings to protect in the more intense unit of some radiation sources.
Summary of the invention:
Purpose of the present invention is exactly that a kind of new shielding will be provided, and it can overcome the existing problem of Vintage Product effectively, can the target that some are important stash, thereby plays the purpose of protecting oneself; Also can apply to some needs radiation-resistant place, plays the purpose that prevents radiate source radiation.The object of the present invention is achieved like this, the gauze screen draw off gear, be by main shaft, drive sprocket, shaft stool, the guide rail holder, gauze screen is formed, it is characterized in that: the both sides of gauze screen are provided with guide rail, upper end at guide rail is provided with main shaft, end at main shaft is provided with drive sprocket, one end of main shaft is fixed on the guide rail by shaft stool, described main shaft is provided with gauze screen, gauze screen is provided with several slide blocks on the both sides of net, slide up and down in the guide rail that described slide block can be provided with in the both sides of gauze screen, be provided with the bottom in the lower end of gauze screen and hang down heavy; Be provided with guide rail holder and hand gear at the middle part of a side rails, the stopping means that is respectively arranged with two gauze screens at the top and the middle part of opposite side guide rail; Be provided with dynamical system in the guide rail lower end that is provided with the guide rail holder.
The present invention operates steadily, and is simple in structure, easy to operate, can be electronic, also can be manual, and shielding property is good, the reliability height.
Description of drawings:
Fig. 1 is a gauze screen draw off gear structural representation of the present invention
1, main shaft 2, drive sprocket 3, shaft stool 4, guide rail holder 5, hand gear 6, dynamical system 7, gauze screen 8, guide rail 9, gauze screen stopping means 10, vertical heavy by 11, the vertical great trust frame 12 in bottom, gauze screen stopping means
Embodiment:
The invention will be further described below in conjunction with accompanying drawing
In the embodiment shown in fig. 1, the gauze screen draw off gear, be by main shaft, drive sprocket, shaft stool, the guide rail holder, gauze screen is formed, the dynamical system that is arranged on the guide rail bottom is made up of motor and deceleration device, power after the deceleration is by chain drive, with transmission of power to the drive sprocket of main shaft, drive main axis rotation, twist under gauze screen on the main shaft hangs down heavy action of gravity in the bottom, can be along balanced up and down the moving of guide rail, in the setting of guide rail opposite side, following gauze screen stopping means can be controlled the online position of motion down of shielding effectively.And be arranged on the vertical great trust frame of two sides in the middle part of the main shaft, and its objective is when gauze screen all twists on the main shaft, under preventing that gauze screen from hanging down heavy action of gravity in the bottom, freely glide, and setting.When running into power supply and break down, the gauze screen draw off gear also can manual operation.
