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.

[0031] As attached Figure 1-6 As shown, an embodiment of the utility model is provided: a rolling door steel belt unwinding guide device, including a mounting plate 1, the left and right sides of the mounting plate 1 are fixedly connected with an outer tube 2, the inner side of the outer tube 2 is slidably connected with an adjusting column 3, the left and right sides of the outer tube 2 are provided with a plurality of hole grooves 4, the inner side of one end of the adjusting column 3 is provided with a mounting groove 5, the inner side of the mounting groove 5 is provided with a spring 1 6, both ends of the spring 1 6 are fixedly connected with a clamping block 7, the other end of the adjusting column 3 is fixedly connected with a mounting shell 8, the inner middle part of the mounting shell 8 is rotatably connected with a bidirectional screw rod 9, the upper and lower ends of the bidirectional screw rod 9 are threadedly connected with a clamping block 10, A plurality of circular grooves 11 are provided at the top of the mounting shell 8, a knob 12 is fixedly connected to the other end of the bidirectional screw rod 9, a fixing plate 15 is fixedly connected to the rear side of the knob 12, a clamping rod 13 passes through the middle of the fixing plate 15, a spring 2 14 is fixedly connected to the top of the clamping rod 13, and the other end of the spring 2 14 is fixedly connected to the top of the fixing plate 15, and the circular groove 11 is arranged in an annular shape, which is convenient for clamping the mounting rod for mounting the reel, so that the guide device is fixed on the mounting rod in the rolling door, so that when the steel belt in the rolling door is repaired and replaced, there is no need to remove the reel, thereby reducing the difficulty of repairing the steel belt.

[0032] As attached Figure 5 As shown, the top of the mounting plate 1 is fixedly connected to a fixed frame 16, and slide grooves 17 are provided on both sides of the top of the fixed frame 16, and multiple square grooves 26 are provided on both sides of the top of the fixed frame 16. The setting of the slide groove 17 facilitates the guide column 18 to drive the rotating roller 19, which can be flexibly adjusted according to the width of the steel belt, thereby improving the adaptability to the steel belt.

[0033] As attached Figure 1 As shown, the inner side of the slide groove 17 is slidably connected to a guide column 18, the outer side of the guide column 18 is rotatably connected to a rotating roller 19, and the top of the guide column 18 is fixedly connected to a fixing box 20. The rotating roller 19 facilitates the movement of the auxiliary steel belt, and the fixing box 20 facilitates the installation of a stabilizing block 21.

[0034] As attached Figure 6As shown, the inner side of the fixed box 20 is slidably connected with a stabilizing block 21, the top of the stabilizing block 21 is fixedly connected with a connecting rod 22, the top of the stabilizing block 21 is fixedly connected with a pushing spring 23, and the other end of the connecting rod 22 is fixedly connected with a pulling block 24, which is convenient for fixing the position of the guide column 18 after the movement, thereby preventing the guide column 18 from being offset and reducing the guiding effect.

[0035] As attached Figure 2 As shown, a plurality of anti-slip strips 27 are provided on the inner side of the clamping block 10, and cleaning brushes 25 are fixedly connected to the upper and lower ends of the rear side of the fixed frame 16. The provision of the anti-slip strips 27 is conducive to enhancing the stability of the clamping of the mounting rod in the rolling door, and the provision of the cleaning brush 25 is conducive to cleaning the dust on both sides of the steel belt, thereby reducing the corrosion of the steel belt by dust.

[0036] Working principle: when the guide device needs to be installed in the rod for installing the reel, the multiple clamping blocks 10 in the guide device are placed on the upper and lower sides of the rolling door rod, so that the rolling door rod is placed in the middle of the multiple clamping blocks 10, and then the clamping rods 13 on both sides are pulled apart, so that when the clamping rod 13 pulls the spring 2 14, it disengages from the inner side of the corresponding circular groove 11, and then the knob 12 is rotated, so that the knob 12 drives the two-way screw rod 9 to rotate, and the two-way screw rod 9 drives the clamping blocks 10 on the upper and lower sides to approach each other, so that the two clamping blocks 10 clamp and fix the mounting rod of the rolling door, and then the clamping rod 13 is released, so that the clamping rod 13 rebounds to the inside of the corresponding circular groove 11 under the action of the spring 2 14, thereby fixing the rotated knob 12, making it easier to install the guide device in the mounting rod of the rolling door, thereby reducing the difficulty of working when unwinding the steel belt, and then when rewinding the steel belt When unwinding, the steel belt in the reel is pulled out and passed through the inside of the fixed frame 16, and then the pull blocks 24 on both sides are pulled, so that the pull blocks 24 drive the connecting rod 22 to be pulled, thereby pulling to the stabilizing block 21, and the stabilizing block 21 is pulled out from the inner side of the corresponding square groove 26, thereby squeezing the pushing spring 23, and then the guide columns 18 on both sides are moved, so that the guide columns 18 drive the rotating roller 19 to move, thereby adjusting according to the width of the steel belt. After adjustment, the pull blocks 24 are released, so that the stabilizing block 21 is pushed down by the rebound of the pushing spring 23 and the stabilizing block 21 is pushed to the inside of the corresponding square groove 26, thereby fixing the position of the rotating roller 19, so that when the steel belt is pulled, the rotating roller 19 provides a limiting auxiliary function, and the steel belt passes through the middle of the two cleaning brushes 25, which is conducive to cleaning the dust on both sides of the steel belt when the steel belt is pulled, thereby reducing the accumulation of dust.
