Abstract
The utility model relates to a spring energy storage type roll shutter which is composed of a support frame, a winding drum and a positioning seat. The inner cavity of the winding drum is provided with a spring energy storage mechanism. A buckled seat fixed with the winding drum is connected with a speed change mechanism. One end of the spring is fixed with a positioning sleeve A which is fixed with the support frame and the positioning seat through a main shaft. The other end of the spring is fixed on a positioning sleeve B tightly matched with the winding drum. The positioning sleeve B can rotate following the winding drum to drive one end of the spring to rotate and to store the energy. The utility model utilizes the spring energy storage mechanism and a gear speed change mechanism to cause the roll shutter to flexibly and stablyrun upward and downwards. The product has the advantages of reliable performance, simple structure, small size and low cost.
Description
The utility model relates to a kind of spring energy-storage roller shutter, is a kind of lifting gear of roller shutter.
The roller shutter of Xiao Shouing is divided into catapult formula and bead type in the market, and is lighter because of the gravity relation when drop-down with the door and window that this structure is made, but very hard when last drawing, so bring many inconvenience for the opening of roller shutter.In order to overcome the defective of prior art, the roller blind device of different structure and form successively comes out.The patent No. " 89210699 ", " the automatic rolling up curtains box of spring ", the patent No. is " 952111456 ", " a kind of automatic curtain device ", the patent No. " 94226599 ", " automatic metal roll-type window or door " or the like, all utilize the release of spring torsional deflection energy, solve the defective that traditional roller shutter exists, the former, structure is very simple, but only be applicable to the curtain that the room is commonly used, middle a kind of roller blind device, except that spring storage mechanism is housed, ratchet lock mechanism also is housed, also only be suitable for the curtain in general room, the latter's automatic metal roll-type window or door, adopt the common mode that drives of spring drive and motor driver to realize the keying of roller shutter, though performance is good, cost is higher relatively.
The purpose of this utility model is at the defective of prior art, provides a kind of new varieties of spring energy-storage roller shutter to society, to satisfy the demand of society.
Task of the present utility model is achieved in that the positioning seat that this spring energy-storage roller shutter fixes by support, reel, with support is formed, a spring energy agency is housed in reel, with gear of connection on the mutually friction tight Button Block of reel one end, spring in the spring energy agency, one end and positioning sleeve A fix, this positioning sleeve A fixes by main shaft and positioning seat and support, the other end of spring be fixed on the friction tight positioning sleeve B of reel on, positioning sleeve B can tighten or reply with the reel rotating band spring of moving; Spring in the spring energy agency is between interior cover of spring and the spring overcoat, and the length of spring overcoat is greater than the drift of spring; Described gear is by sprocket wheel, planetary gear, pinion stand and gearcase are formed, be entrenched in uniform several planetary gears of fixing on the pinion stand on the Button Block, its periphery all is meshed with the internal tooth of rack-mount gearcase, all be meshed in the middle of it, cloudy Buddhist nun's sheet is housed between planetary gear and the sprocket wheel with the master gear of sprocket wheel.
The utility model is separately fixed at spring two ends on the positioning sleeve A and the positioning sleeve B by the reel driven rotary that remains static, an end that makes spring can be with reel rotation and the storage and the release of energy are carried out in torsional deflection, increased the turning power of roller shutter, improved the folding performance of roller shutter, place respectively on the internal and external circumferential of spring simultaneously that cover and spring overcoat twist when rotated to avoid spring in the spring, improved reliability of products like this.Moreover, adopt gear shift to drive the reel rotation, it is more steady that roller shutter is moved up and down, reliable, improved sensitivity, saves cost again, reduces cost.
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Shown in the accompanying drawing, the support 1 of two limit symmetries, 1 ', be fixed on the body of wall that needs the dress roller shutter, one end of support 1 is fixed a positioning seat with screw, the below of positioning seat 2 is provided with a movable buckle 3, positioning sleeve A5 and main shaft 6 tight fits, and be fixed on the positioning seat 2 by movable buckle 3, one end of spring 8 and positioning sleeve A5 hook, place cover 7 in the spring in the spring 8, spring overcoat 10 is sleeved on spring 8 peripheries, and the length of this spring overcoat 10 is greater than the drift of spring 8, when mounted, as long as pull-off spring 8 hooks together its other end on positioning sleeve B9.Reel 11 is a hollow tube-shape, in establish three the card keys, these three the card key respectively with bearing support 4, positioning sleeve B9, Button Block 12 fastens, one side of pinion stand 13 and Button Block 12 tablings, pinion stand 13 is provided with three uniform convexes, fixes a planetary gear 15 on each convex, and the periphery of planetary gear 15 is provided with gearcase 14, the internal tooth of this gearcase 14 is meshed with planetary gear 15, and a side and the mounting bracket 1 ' of gearcase 14 fix.The centre of three planetary gears 15 is meshed with the master gear of sprocket wheel 17, sprocket wheel 17 is installed on the support 1 ' by sprocket spindle, between planetary gear 15 and sprocket wheel 17, damping fin 16 is housed, to limit the velocity of rotation of planetary gear 15, cord twists on the periphery wall of reel 11, bead links to each other with sprocket wheel 17 by backguy, the pulling bead, sprocket wheel 17 is rotated, the master gear of sprocket wheel 17 drives planetary gear 15 rotations, thereby make pinion stand 13 rotations, drive Button Block 12 and reel 11 rotations, the positioning sleeve B9 that connects spring 8 one ends is also rotated with reel, make spring 8 tighten storage power, cord slowly descends.If the opposite side pulling bead at sprocket wheel 17 makes reel 11 opposite spins, and is because the restoring force of spring 8 in like manner makes cord scroll up, not only laborsaving but also flexible like this.
If when needing to take out reel 11,, skid off left end reel 11 as long as open bayonet socket 3, extract right-hand member out, can successfully take out reel, dismounting is very convenient.
