AI Technical Summary
The existing electric roller shutter doors and windows are easily pried from the bottom due to the gap between the curtains, and lack effective anti-plitting measures.
An electric roller shutter door and window anti-plitting bottom beam is designed, including the upper part of the bottom beam and the lower part of the bottom beam. The upper part of the bottom beam is equipped with a lock body, a lock bolt, a contact switch and an extension part. The lower part of the bottom beam is equipped with a skid groove and a screw hole, through The extension covers the lower part of the bottom beam and closely cooperates with the anti-skid groove to form a engaging structure to prevent the crowbar from entering.
When the roller shutter doors and windows are closed, the upper part of the bottom beam covers the lower part of the bottom beam to form a tight fit, effectively preventing the crowbar from entering and achieving a good anti-plitting function.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric doors and windows, in particular to an anti-pry bottom beam for electric rolling shutter doors and windows. Background Art
[0002] Electric rolling shutter doors and windows are made of curtain pieces hinged in sequence. They are easy to open and have a small storage space. However, due to the gaps between the curtain pieces of the rolling shutter doors, they can be easily pried open from the bottom. Utility Model Content
[0003] In order to make up for the above shortcomings, the utility model provides an anti-pry bottom beam for electric rolling shutter doors and windows, aiming to improve the problem of "rolling shutter doors being pried open from the bottom" mentioned in the prior art.
[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anti-theft bottom beam for electric rolling shutter doors and windows, including an upper bottom beam portion and a lower bottom beam portion, characterized in that a lock body is arranged at the upper end of the upper bottom beam portion, a lock bolt is arranged at the lower part of the lock body, a contact switch is arranged at the lower middle position of the upper bottom beam portion, an extension portion is arranged at the bottom end of the upper bottom beam portion, the extension portion covers the lower bottom beam portion, a screw hole is arranged at the middle position of the lower bottom beam portion, and a limit strip is arranged at the upper bottom beam portion near the bottom end.
[0005] As a further description of the above technical solution:
[0006] Two anti-pry grooves are symmetrically arranged at the lower part of the bottom beam, the anti-pry grooves are closely matched with the extension part, and wool strip installation grooves are respectively arranged at both ends of the lower part of the bottom beam.
[0007] As a further description of the above technical solution:
[0008] The bottom end of the upper part of the bottom beam and the bottom end of the lower part of the bottom beam are in the same horizontal plane.
[0009] The utility model has the following beneficial effects:
[0010] During the closing process of the rolling shutter door and window, the lower part of the bottom beam stops moving after touching the ground. At this time, the upper part of the bottom beam still moves downward, and the entire upper part of the bottom beam covers the lower part of the bottom beam. After it is fully closed, the outer side of the extended part of the upper part of the bottom beam is just engaged in the prying groove, forming a tight fit. At this time, the crowbar cannot extend into the gap between the upper part of the bottom beam and the lower part of the bottom beam, thereby achieving a good anti-pry function. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a schematic diagram of the structure of the utility model;
[0012] Figure 2 This is a schematic diagram of the structure of the utility model after being fully closed;
[0013] Figure 3 This is another schematic diagram of the structure of the utility model after being completely closed. DETAILED DESCRIPTION
[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1
[0015] Reference Figure 1 , Figure 2 The utility model provides an embodiment: an anti-pry bottom beam for electric rolling shutter doors and windows, comprising an upper bottom beam portion 1 and a lower bottom beam portion 2, characterized in that a lock body 3 is arranged at the upper end of the upper bottom beam portion 1, a lock bolt 4 is arranged at the lower part of the lock body 3, a contact switch 5 is arranged at the lower middle position of the upper bottom beam portion 1, an extension portion 10 is arranged at the bottom end of the upper bottom beam portion 1, the extension portion 10 covers the lower bottom beam portion 2, a screw hole 7 is arranged at the middle position of the lower bottom beam portion 2, a limit strip 9 is arranged near the bottom end of the upper bottom beam portion 1, and two anti-pry grooves 6 are symmetrically arranged at the lower bottom beam portion 2, The anti-pry groove 6 is closely matched with the extension part 10, and the two ends of the lower part 2 of the bottom beam are respectively provided with wool strip installation grooves 8. When the rolling door is closed, the upper part 1 of the bottom beam moves downward due to the weight of the curtain piece. In the process of the top of the lower part 2 of the bottom beam pushing the contact switch 5 upward, the lock bolt 4 pops out to lock the bottom beam on the track, and the bottom edge of the upper part 1 of the bottom beam is hidden in the anti-pry groove 6 to realize the anti-pry of the rolling door. Conversely, when the motor opens the rolling door, the upper part 1 of the bottom beam and the lower part 2 of the bottom beam open a gap, the contact switch 5 returns to its position, and the lock bolt 4 automatically retracts into the bottom beam 1 to realize the opening of the rolling door. Example 2
[0016] Reference Figure 3 The utility model provides an embodiment: an anti-theft bottom beam for an electric rolling shutter door and window, comprising a bottom beam upper part 1 and a bottom beam lower part 2, characterized in that a lock body 3 is arranged at the upper end of the bottom beam upper part 1, a lock bolt 4 is arranged at the lower part of the lock body 3, a contact switch 5 is arranged at the lower middle position of the bottom beam upper part 1, an extension part 10 is arranged at the bottom end of the bottom beam upper part 1, the extension part 10 covers the bottom beam lower part 2, a screw hole 7 is arranged at the middle position of the bottom beam lower part 2, a limiting strip 9 is arranged near the bottom end of the bottom beam upper part 1, the bottom end of the bottom beam upper part 1 and the bottom end of the bottom beam lower part 2 are in the same horizontal plane, and after the entire rolling shutter door and window are completely closed, the bottom beam lower part 2 is hidden inside the bottom beam upper part 1, which is suitable for the rolling shutter window structure, thereby realizing the bottom beam integrated structure.
[0017] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
