Abstract
Large-scale manual external sunshade roller shutters comprise a heat preservation shutter plate and a torsion spring. A transmission shaft is arranged in a housing, an inner cavity of the transmission shaft is hollow, the torsion spring is arranged in the inner cavity, and two ends of the torsion spring are respectively connected with two end faces of the transmission shaft. An outer ring of the transmission shaft is arranged into an octagon shape, a shaft sleeve is sleeved on the transmission shaft, and an octagon shape of an inner ring is matched with the outer ring of the transmission shaft. Torsion of the built-in torsion spring is matched with the weight of heat preservation shutter cloth. One end of a spring plate is riveted with the outer ring of the transmission shaft, and the other end of the spring plate is connected with the heat preservation shutter plate. Two ends of the heat preservation shutter plate are provided with lateral buttons, and the lateral buttons are arranged on tracks on two sides. The large-scale manual external sunshade roller shutters can improve indoor installing environment and are small in installing space, simple in installing structure, attractive in appearance and capable of prolonging service life of the heat preservation shutter plate.
Description
Technical field:
The utility model relates to a kind of large-scale manual external sunshade roller shutter.
Background technology:
Present manual external sunshade roller shutter often adopts hand steel wire when area is big, carry out the opening and closing roller shutter through reducer.Because hand steel wire installing space is big, limited by the place, and is not attractive in appearance in the installation room, in the more suitable installation of specific occasions.
Summary of the invention:
The purpose of the utility model will provide a kind of large-scale manual external sunshade roller shutter exactly, and it can overcome the deficiency of above prior art.The purpose of the utility model is achieved in that a kind of large-scale manual external sunshade roller shutter, comprises the heat holding curtain sheet; Torsion spring is characterized in that: be provided with power transmission shaft in the case, its inner chamber is set to hollow; Built-in torsion spring, the two ends of torsion spring are connected with the both ends of the surface of power transmission shaft respectively; Octagon is arranged in the power transmission shaft outer ring, and axle sleeve is enclosed within on the power transmission shaft, and the octagon of its inner ring setting matches with the power transmission shaft outer ring; The torsion of described built-in torsion spring is complementary with insulation cord weight; Spring leaf one end and the riveted joint of power transmission shaft outer ring, the other end is connected with the heat holding curtain sheet; The two ends of described heat holding curtain sheet are provided with the side button, and described side button is arranged in the track of both sides.The utility model can improve indoor installation environment, and installing space is little, and mounting structure is simple, and is specious, can improve the application life of heat holding curtain sheet.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model is installed in the sketch map on the body of wall;
1. case, 2. axle sleeve, 3. torsion spring, 4. power transmission shaft, 5. side button, 6. insulation cord, 7. spring leaf, 8. expansion bolt.
The specific embodiment: the utility model is described further below in conjunction with accompanying drawing;
A kind of large-scale manual external sunshade roller shutter comprises heat holding curtain sheet 6, and torsion spring 3 is characterized in that: be provided with power transmission shaft 4 in the case 1, its inner chamber is set to hollow, built-in torsion spring 3, and the two ends of torsion spring 3 are connected with the both ends of the surface of power transmission shaft 4 respectively; Octagon is arranged in power transmission shaft 4 outer rings, and axle sleeve 2 is enclosed within on the power transmission shaft 4, and the octagon of its inner ring setting matches with the power transmission shaft outer ring; The torsion of described built-in torsion spring 3 is complementary with insulation cord 6 weight; Spring leaf 7 one ends and the riveted joint of power transmission shaft 4 outer rings, the other end is connected with heat holding curtain sheet 6; The two ends of described heat holding curtain sheet 6 are provided with side button 5, and described side button 5 is arranged in the track of both sides.
During practical implementation, as shown in Figure 2, case is installed on the body of wall of right angle face by some expansion bolt M8X25.Described side button adopts the nylon manufacturing, and lubricated and guide effect are played in the two ends that are arranged on the insulation cord.Described sleeve diameter and power transmission shaft outer ring are set to octagon and join work, and the heat holding curtain sheet is arranged on the axle sleeve when rolling, and axle sleeve can play the effect that abates the noise and reduce friction, protects power transmission shaft.Adopt manual belt box to link to each other with anistree axle through belt pulley.Because the balance sysmte that has adopted the weight of torsion spring torsion and heat holding curtain sheet to be complementary only need overcome the frictional resistance that the heat holding curtain sheet is produced so pull the pulling force of belt box in orbital motion.
