Abstract
The invention relates to a roller shutter limiting mechanism, comprising a threaded rod, a positioning link stopper and a baffle plate, wherein, the threaded rod is fixedly connected with a curtain bracket; the positioning link stopper provided with a protruded link stopper is in threaded connection with the threaded rod and is in horizontal sliding connection with a roller shutter winding drum; and the baffle plate is arranged at the inner side of the end head of the threaded rod. The roller shutter limiting mechanism is characterized in that a rotary seat is arranged at the inner side of the end head of the threaded rod in a threaded spinning mode; a torsion spring is fixedly connected between the rotary seat and the end head of the threaded rod; and the baffle plate is arranged at the inner side of the rotary seat. Compared with the prior art, the roller shutter limiting mechanism can effectively prevent the positioning link stopper and the baffle plate from being physically damaged, and has the advantages of reliable running and high durability.
Description
Technical field:
The present invention relates to a kind of curtain mechanism.
Background technology:
Existing control roller shutter opens/and the roller shutter limiting mechanism such as the patent 200820044961.2 of the amplitude of rolling is disclosed; Be by with Curtain rod 1 having of being fixed together externally threaded cover 8, be threaded on the cover 8 and constitute (as shown in Figure 3) with the position block 9 that has protrusion block 9a that roller shutter reel 5 links together, be provided with baffle plate 12 in the inboard, termination of cover.During use; Through preestablishing the length that position block 9 is confirmed the reel rolling in the position of cover on 8 or discharged curtain, and be issued to automatically the length with setting perhaps discharges with curtain the curtain rolling from reel purpose in the cooperation of other mechanism (like clutch and one-directional rotation mechanism etc.) of roller shutter.This kind roller shutter limiting mechanism is because the protrusion block 9a of position block 9 is hard the contact with 12 on baffle plate; And no matter be that the curtain rolling perhaps discharges curtain from reel; The impact force that running is accumulated all concentrates on the protrusion block 8a of position block 8 and the moment that baffle plate 12 is collided at last; Make the protrusion block 9a and the baffle plate 12 of position block 9 all receive very big impact force; Under frequent impact, the protrusion block 9a and the baffle plate 12 of position block 9 must receive the damage of physics, thereby cause the damage of roller shutter limiting mechanism.
Summary of the invention:
Goal of the invention of the present invention is to provide a kind of position block and baffle plate of effectively preventing to receive roller shutter limiting mechanism damage, reliable, durable of physics.
The present invention realizes like this; Comprise the screw rod that is fixed together with Curtain rod, be threaded on the screw rod and laterally be slidingly connected having the position block that protrudes block, be arranged on the inboard baffle plate of screw end head together with the roller shutter reel; Its special feature is to be connected with rotation seat at the screw end head inside thread; Between rotation seat and screw end head, be fixedly connected with torque spring, baffle plate is arranged on the inboard of rotation seat.During work; Through preestablishing the length that the position of position block on screw rod confirmed the reel rolling or discharged curtain; And under the cooperation of other mechanism (like clutch and one-directional rotation mechanism etc.) of roller shutter with the length set with the curtain rolling or curtain is discharged from reel; When the protrusion block of position block leans against on the baffle plate; The impact force removal that torque spring is accumulated running realizes that the protrusion block of position block contacts with baffle plate is soft, thus avoid the protrusion block of position block to contact firmly effectively with baffle plate and the very big impact force that produces to both injury; Prevent that effectively position block and baffle plate from receiving the damage of physics, improved the operational reliability and the durability of device.
Compared with present technology the present invention has and can prevent effectively that position block and baffle plate from receiving advantage damage, reliable, durable of physics.

Fig. 1 is the structural representation of the embodiment of the invention 1;
Fig. 2 is the structural representation of the embodiment of the invention 2;
Fig. 3 is the structural representation of prior art.
The specific embodiment:
Combine accompanying drawing and embodiment that the present invention is described in further detail at present:
Embodiment 1: as shown in Figure 1; The present invention includes the stay cord rotating disk box 2 that is fixed on the Curtain rod 1, rotate the stay cord rotating disk 4 that is wound with stay cord 3 that is arranged in stay cord rotating disk box 2 sons, rotate curtain reel 5 on the spool shaft 14 that is arranged on stay cord rotating disk box 2, be arranged on one-way clutch 6 formations of curtain reel 5 and 4 of stay cord rotating disks; Stay cord rotating disk 4 and 2 in stay cord rotating disk box are provided with backrush spring 7; One screw rod 8 is set in curtain reel 5, and screw rod 8 links together with stay cord rotating disk box 2, be threaded on the screw rod 8 one have a protrusion block 9a position block 9; Position block 9 laterally is slidingly connected in the curtain reel 5; Be connected with rotation seat 10 at screw rod 8 termination inside threads, between rotation seat 10 and screw rod 8 terminations, be fixedly connected with torque spring 11, be provided with baffle plate 12 in rotation seat 10 inboards.Connect one at the clutch end 6a of one-way clutch 6 and have the driving shaft 13 that drives connection 13a, drive connection 13a and be connected with curtain reel 5, screw rod 8 is shell-like and turning set is connected on the driving shaft 13.During work; The screw rod 8 that links together with stay cord rotating disk box 2 can not rotate; And the driving shaft 13 that is connected with curtain reel 5, position block 9 are to rotate with the rotation of curtain reel 5, and stay cord rotating disk 4 drives curtain reels 5 and rotates through one-way clutch 6, driving shaft 13, make curtain reel 5 make the rolling curtain according to designing requirement or discharge the work of curtain; 12 rotations along with curtain reel 5 of position block move forward and backward; Protrusion block 9a on position block 9 leans against 12 last times of baffle plate, and the impact force removal that torque spring 11 is accumulated running is realized the protrusion block 9a and baffle plate 12 soft contacts of position block 9.
Embodiment 2: as shown in Figure 2; The present invention includes screw rod 8, be threaded on the screw rod 8 and with roller shutter reel 5 laterally be slidingly connected together the position block 9 that has protrusion block 9a, be arranged on the inboard baffle plate 12 in screw rod 8 terminations, be embedded in the reel pedestal 14 of roller shutter reel 5 ends; Screw rod 8 rotates cross-under on reel pedestal 14 bracing frames 16; Bracing frame 16 is connected with roller shutter reel 5; Its special feature is to be connected with rotation seat 10 at screw rod 8 termination inside threads, between rotation seat 10 and screw rod 8 terminations, is fixedly connected with torque spring 11, and baffle plate 12 is arranged on the inboard of rotation seat 10.During use; Can be connected with Curtain rod 1 through a screw rod governor motion 15; Like this, can pass through screw rod governor motion 15 rotating screw bolts, to regulate the position of position block 9 on screw rod; Thereby confirm the number of turns that roller shutter reel 5 can rotate by the rotation direction of setting, confirm curtain rolling or the length that discharges then.The turn 11a at torque spring 11 middle parts is separated from each other, so that rotation seat 10 can dwindle around torque spring 11 when rotating toward torque spring 11, so that rotation seat 10 can be along screw rod 8 threads turn.
