[0038] With reference to Figure 2 , Figure 3 and Figure 4The utility model provides an embodiment: the outer wall left side fixed connection of left guide rail 13 has the sliding cover 14, the top fixed connection of guide rail 13 has the dust cover 21, the top fixed connection of dust cover 21 has a plurality of connecting blocks 22, the outer wall of a plurality of connecting blocks 22 all is equipped with bolt hole 23, the bottom fixed connection of roll up door panel 19 has the engaging strip 24, the left side of engaging strip 24 is equipped with recess two 25,

[0039] Specifically, on the left side of the device, the outer wall left side of guide rail 13 is fixedly connected with a sliding cover 14, which can control block 203 to be free from the influence of external factors, and the top of guide rail 13 is fixedly connected with a dust cover 21, which can effectively prevent dust and other impurities from falling into the device, thereby ensuring normal operation thereof. The top of dust cover 21 is fixedly connected with a plurality of connecting blocks 22, the outer walls of which are all provided with bolt holes 23 for facilitating connection and fixation with a wall body. The bottom of roll up door panel 19 is fixedly connected with an engaging strip 24, which can be engaged with guide rail 13, thereby ensuring the stability of roll up door panel 19.

[0040] Working principle: when the device is contracted, the roller 1 first starts to rotate, thereby driving roll up door panel 19 to be wound on the roller 1. Since the gear 4 is fixed on the outer wall of roller 1 and is in meshing connection with the rack 3, when roller 1 rotates, the support arm 5 will be moved forward and backward. When roll up door panel 19 is completely wound on the outer wall of roller 1, the support arm 5 slides to the most front end. At this time, the sliding block two 11 controlled by spring one 10 penetrates the square hole 12 and is engaged in the recess one 7 formed in the sliding block one 6, thereby controlling the support arm 5 from moving forward any more. When roller 1 releases roll up door panel 19 wound thereon, the support arm 5 slides backward. Since one side of sliding block two 11 has a curvature, the support arm 5 will not be hindered when sliding backward by relying on sliding block one 6. Thus, roll up door panel 19 can keep consistent with the position of guide rail 13 when being contracted and released;

[0041] Furthermore, when roll up door panel 19 is contracted upward, the clamping block 205 will touch the outer wall of roll up door panel 19 and be slightly turned upward. At the same time, spring two 206 will exert a downward pressure, so that the clamping block 205 will not be separated from roll up door panel 19. When roll up door panel 19 is maximally contracted and placed on roller 1, the clamping block 205 will penetrate the limiting hole 207 and be engaged with the recess two 25 formed in the engaging strip 24, thereby controlling roll up door panel 19 from falling off. When roll up door panel 19 is released downward, the telescopic rod 202 will slide the control block 203 backward, so that the clamping block 205 is separated from the limiting hole 207 and no longer adheres to roll up door panel 19. Thus, the clamping block 205 can stably control roll up door panel 19 when being contracted, and will not affect the normal release of roll up door panel 19.

[0042] It should be pointed out finally that: the above only for the preferred embodiments of the utility model have, and do not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. that is made within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
