[0027] Specifically, the front side upper portion between two first support columns 1 is detachably fixedly installed with a door blocking plate 5, which is used for blocking the prying force from above the roller shutter door, preventing illegal persons from inserting tools to pry the roller shutter door from the gap between the top of the roller shutter door and the support frame, and the bottom between two first support columns 1 is detachably fixedly installed with a pick-resistant plate 6, which is embedded into the ground, and the upper edge thereof is higher than the ground, and the pick-resistant plate 6 can effectively resist the door prying behavior from the bottom, such as Figure 2 , 3As shown, the rear middle part between the two first support columns 1 is detachably fixedly installed with a support plate 7, the support plate 7 is fixedly installed with an extension piece 8 through bolts, the extension piece adopts an electric push rod, a gas cylinder or a hydraulic cylinder, and is preferably an electric push rod, the specific structure and circuit control of the electric push rod are not within the protection scope of the present application, and will not be described here again, the extension end of the extension piece 8 is fixedly connected with the lower part of the rear side of the roller shutter door body 3 through bolts, and the extension of the extension piece 8 can drive the roller shutter door body 3 to move up and down, which can not only ensure the stable lifting of the roller shutter door body 3, but also provide a certain supporting force for the entire door body; the top end of the first support column 1 and the end of the second support column 2 are detachably fixedly connected with a first reinforcing piece 9, and the bottom end of the first support column 1 and the end of the anti-prying plate 6 are detachably fixedly connected with a second reinforcing piece 10; the above-mentioned door blocking plate 5, support plate 7, first reinforcing piece 9 and second reinforcing piece 10 are detachably fixedly connected between the locking groove 4 of the support frame through the locking piece 11, which ensures that the components are tightly connected and will not loosen due to external force, and further protects the prying performance of the roller shutter door.

[0028] Specifically, the upper surface of the anti-prying plate 6 is provided with a transverse limiting groove 15, and the lower end of the roller shutter door body 3 can extend into the limiting groove 15, so that when the roller shutter door body 3 is closed, the bottom of the door body is clamped by the limiting groove 15, and even if the bottom is subjected to upward prying force, it is also difficult to be pried up, forming double protection for the bottom of the roller shutter door.

[0029] Specifically, as shown in Figure 4 The locking groove 4 adopts a T-shaped groove, which makes the locking piece 11 matched therewith not easy to come out after installation, increases the reliability of the connection, and can better resist external force pulling from all directions compared with ordinary straight grooves, and prevents the components from loosening.

[0030] Specifically, the locking piece 11 is composed of a locking block 12 and a locking bolt 13 threadedly connected with the locking block 12, the locking block 12 is slidingly connected in the locking groove 4, and the two ends of the locking block 12 are integrally provided with locking portions 14 extending outward, the width between the two locking portions 14 is greater than the width of one side of the opening of the locking groove 4, when installing, the locking block 12 is slid into the locking groove 4, due to the design of the locking portions 14, the locking block 12 cannot come out from the slot, and then by tightening the locking bolt 13, the components to be fixed can be tightly pressed on the support frame, which is simple to operate and has excellent fixing effect.

[0031] Example 2:

[0032] As shown in Figure 1As shown, this utility model discloses another technical solution, a roller shutter door anti-pry mechanism, which differs from embodiment 1 in that the upper two ends of the above-mentioned door blocking plate 5 are fixedly connected to the second support column 2 by locking member 11, and the lower two ends of the door blocking plate 5 are fixedly connected to the first support column 1 on both sides by locking member 11. The multi-point fixing method makes the door blocking plate 5 and the support frame form a solid whole, which can effectively block the prying from above and ensure the safety of the top of the roller shutter door body 3.

[0033] Example 3:

[0034] like Figure 1 , 2 As shown, this utility model discloses another technical solution, a roller shutter door anti-pry mechanism, which differs from embodiment 1 in that the first reinforcing member 9 adopts a right-angled triangular plate structure, and the two right-angled sides are fixedly connected to the first support column 1 and the second support column 2 by locking member 11 respectively. By utilizing the stability principle of triangle, the first support column 1 and the second support column 2 are firmly fixed, which enhances the deformation resistance of the top of the support frame and can maintain structural stability even when subjected to large external impact.

[0035] Example 4:

[0036] like Figure 1 , 2 As shown, this utility model discloses another technical solution, a roller shutter door anti-pry mechanism, which differs from embodiment 1 in that the second reinforcing member 10 adopts a right-angled triangular block structure. One side of it is fixedly connected to the first support column 1 through the locking member 11, and the other side is fixedly connected to the anti-pry plate 6 through bolts. Based on the stability of the triangle, the connection between the bottom of the support frame and the anti-pry plate 6 is strengthened, so that the anti-pry plate 6 will not separate from the support frame due to the force when resisting the bottom prying force, thus ensuring the protective effect of the bottom of the roller shutter door body 3.

[0037] Specifically, the anti-pry plate 6 adopts an "I" shaped structure. The bottom front and rear sides of the first support column 1 are fixedly connected to the anti-pry plate 6 through the second reinforcing member 10. The anti-pry plate 6 with the "I" shaped structure has high bending strength and load-bearing capacity, and can evenly distribute the prying force from the bottom. Combined with the second reinforcing member 10 on both sides, it forms a stable bottom protection system, which effectively prevents the bottom of the roller shutter door from being pried up.

[0038] The roll-up door anti-prying mechanism provided by the utility model, through the setting of locking groove 4 and locking part 11, makes the door blocking plate 5, support plate 7, anti-prying plate 6, first reinforcing part 9 and second reinforcing part 10 be firmly fixed on the support frame, improves the stability and security of the whole anti-prying mechanism, through the setting of door blocking plate 5, anti-prying plate 6, support plate 7 and matched telescopic part 8, a comprehensive protection system is formed, the door blocking plate 5 resists prying from above, the anti-prying plate 6 protects the bottom, the support plate 7 and telescopic part 8 guarantee the stable lifting of the door body and provide support, the components work cooperatively, the security of the whole roll-up door is greatly improved, effectively responding to the attempt to pry the door from different directions, through the setting of locking groove 4 around the first support column 1 and second support column 2 of the support frame, and the sliding connection of the roll-up door body 3 in the locking groove 4, the connection stability of the roll-up door body 3 and the support frame is greatly enhanced, effectively preventing the door body from being pried from the side, compared with the traditional roll-up door structure, the prying performance is greatly improved, the triangular stable structure formed by the first reinforcing part 9 and second reinforcing part 10 enhances the mechanical properties of the support frame, so that it can withstand greater external force impact without being easily deformed, whether in accidental collision in daily use or in violent prying of the door, the structure can remain complete, ensuring the normal protection function of the roll-up door, through the setting of T-shaped locking groove 4 and the matched locking part 11, not only convenient to install, but also firm and reliable in connection, effectively avoiding the loosening of the components under long-term use or external force, further ensuring the stability and reliability of the roll-up door anti-prying mechanism, reducing the maintenance cost and prolonging the service life.
