Embodiment 1

[0022] Embodiment 1: see figure 1 , figure 2 and Figure 4 , The protective guide rail 2 for the rolling door is located on both sides of the doorway or the outer wall (or inner wall) of the window, including a fixed rail 4 and a guide rail 5 .

[0023] The fixed rail 4 includes a fixed surface 41 against the wall and a vertical surface 42 . The installation hole provided on the fixed surface 41 of the fixed rail 4 is a horizontal strip hole 43, and the fixed surface is directly fixed on the wall 8 by using the expansion screw 6 (or ordinary screw). During the installation process, the wall may need to be drilled. The verticality of the fixed rail can be adjusted through the strip hole 43 . The fixing surface 41 and the wall body 8 can be installed in various ways, and can be arbitrarily fixed according to the actual installation situation of the user. The wall body 8 can be a brick wall, a concrete wall or a metal wall, etc. The vertical surface 42 of the fixed rail 4 i...

Embodiment 2

[0027] Example 2: see figure 1 and image 3 , the content is basically the same as that of Embodiment 1, the difference is that no hook is provided at the joint between the fixed surface of the fixed rail and the outer facade of the guide rail protection groove described in the guide rail protection groove.

Embodiment 3

[0028] Embodiment 3: The accompanying drawings are not drawn, and the content is basically the same as that of Embodiment 1. The difference is that no grooves may be provided on the facade of the guide rail. .

Abstract

The invention discloses a protection guide rail used for a rolling door. The protection guide rail used for the rolling door comprises a fixed rail and a guide rail. A fixed face of the fixed rail is directly fixed on a wall body. A vertical face of the guide rail and a vertical face of the fixed rail are fixed together through screws or rivets. A guide rail protective groove completely seals the fixed rail. A door plate enables all the screws to be hidden in the inner portion after a guide rail sliding groove operates and is closed, the whole structure is stable and reliable, protective performance is good, and the appearance is clean and beautiful. The method of arranging hanging hooks between the fixed rail and the guide rail enables the fixed rail and the guide rail to be tightly clocked, and safety is further improved. A groove in the vertical face of the guide rail enables cap heads of the screws toe be hidden in the inner portion, a curtain slice is enabled to conveniently move up and down, the rolling door freely moves up and down, and no touch phenomenon appears.

Description

Technical field: [0001] The invention relates to the technical field of rolling door guide rails, in particular to a protective guide rail for rolling shutter doors. Background technique: [0002] At present, in the field of rolling door technology, most of the rolling door guide rails are usually fixed on the wall outside the door or window to prevent theft. The existing fixed connection between the guide rail of the rolling shutter door and the outer wall generally takes the following forms: (1) The outer frame of the guide rail is directly welded (or an integral casting), that is, as Figure 5 As shown, there is a fixing piece 59 with a fixing hole, and the guide rail is fixed on the body of wall by screws. (2) Use widened fixed guide rail 9 (closed fixed slot), such as Figure 6 As shown, install holes on the outer side of the fixed guide rail, and use screws to directly fix the fixed guide rail on the wall to achieve guide rail fixation. (3) The widened fixed guide ra...
