Description

Technical Field

[0001] This utility model relates to the field of steel door technology, specifically an auxiliary device for steel door installation. Background Technology

[0002] Steel doors on the market look very similar to security doors. In terms of security performance, standard security doors have thicker steel plates, stronger impact resistance, and comply with national mandatory standards; while steel doors comply with the standards of each company. Steel doors are widely used in the interior and exterior of various buildings.

[0003] A search revealed a Chinese patent with publication number CN217380309U, which discloses an auxiliary device for installing fire doors. During installation, the fire door is placed on a slider, and the frame can then be pushed to move it to the desired installation position. The height of the support platform can be adjusted by rotating the lifting wheel, and simultaneously, the adjusting wheel can be rotated to move the slider and the fire door together, adjusting it to the pre-installation point. This bidirectional adjustment makes installation more convenient and faster.

[0004] While the above solutions can move the fire door along with the slider to adjust it to the pre-installation position, the installation auxiliary device in the above patent is difficult to clamp the steel door, causing positional deviation during installation and affecting the door's sealing and service life. Therefore, we provide an auxiliary device for installing steel doors to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 As shown, this utility model provides a technical solution for an auxiliary device for installing steel doors, including a fixed frame 1. An electric telescopic rod 3 is hinged to one side of the fixed frame 1. The end of the electric telescopic rod 3 away from the mounting frame 201 is hinged to the lower surface of the fixing block 207. The electric telescopic rod 3 is installed on one side of the fixed frame 1, and the other side of the electric telescopic rod 3 is installed on the fixing rod 208. Under the action of the electric telescopic rod 3, the clamping mechanism 2 can be rotated, which facilitates the placement of the steel door body 13 in the device. The fixed frame 1 is provided with a clamping mechanism 2 that can clamp the steel door. The clamping mechanism 2 includes a mounting frame 201 that is hinged to the inside of the fixed frame 1.

[0027] like Figure 4A base 4 is fixedly connected to the lower surface of the mounting bracket 201, and a mounting block 5 is fixedly connected to the upper surface of the base 4. A groove 6 is provided inside the mounting block 5, and a limit plate 8 is slidably connected inside the groove 6. The mounting block 5 is mounted on the base 4. The groove 6 inside the mounting block 5 allows the limit plate 8 to slide inside it, thus playing a limiting role. A buffer 10 is fixedly connected to the lower surface of the limit plate 8. The lower end of the buffer 10 is fixedly connected to the upper surface of the base 4. The buffer 10 is mounted on the limit plate 8 and can automatically adjust the support height according to the weight of the steel door body 13. The other end of the buffer 10 is mounted on the base 4, thus playing a fixing role.

[0028] like Figure 5 As shown, a spring 7 is fixedly connected to the lower surface of the limiting plate 8. The lower surface of the spring 7 away from the limiting plate 8 is fixedly connected to the upper surface of the base 4. The spring 7 is installed on the limiting plate 8 and can support the limiting plate 8 to prevent the limiting plate 8 from failing to automatically reset inside the mounting block 5. The other end of the spring 7 is installed on the base 4 for fixing. A support column 9 is fixedly connected to the upper surface of the limiting plate 8. The upper surface of the support column 9 is engaged with the lower surface of the steel door body 13. The support column 9 is installed on the limiting plate 8 and can push the support column 9 to adjust up and down. The support column 9 can support the steel door body 13 to prevent the steel door body 13 from loosening when moving.

[0029] like Figure 2 As shown, a fixing post 11 is fixedly connected to the upper surface of the base 4, and a mounting plate 12 is fixedly connected to the upper end of the fixing post 11. The fixing posts 11 on both sides are installed on the base 4 for fixing. The mounting plate 12 is installed on the fixing posts 11 on both sides. The clamping mechanism 2 can be fixed by the mounting plate 12 for fixing. A fixing block 207 is fixedly connected inside the mounting frame 201. The telescopic post 203 passes through the fixing block 207 and is slidably connected to the fixing block 207. One side of the mounting frame 201 is fixedly connected to one side of the fixing plate 206. The fixing block 207 is installed inside the mounting frame 201. The telescopic post 203 is installed inside the fixing block 207. When the telescopic post 203 extends or retracts, the telescopic post 203 can be fixed by the fixing block 207 for fixing. The fixing plate 206 is installed on the mounting frame 201 and can guide the clamping frame 205.

[0030] like Figure 3As shown, an electric telescopic cylinder 202 is fixedly connected inside the mounting frame 201. A telescopic column 203 is slidably connected inside the electric telescopic cylinder 202. A fixed rod 208 is fixedly connected to one end of the telescopic column 203 away from the electric telescopic cylinder 202. A movable rod 204 is rotatably connected to one end of the fixed rod 208. A clamping frame 205 is rotatably connected to one end of the movable rod 204 away from the fixed rod 208. A fixed plate 206 is slidably connected to the outer surface of the clamping frame 205. The steel door body 13 is clamped inside the clamping frame 205. When the steel door body 13 is placed on the device, the clamping mechanism 2 is reset under the action of the electric telescopic rod 3. Then, the telescopic column 203 is pushed to extend and retract by the electric telescopic cylinder 202. When the telescopic column 203 extends and retracts, it can push the movable rod 204 and the clamping frame 205 to slide, thereby clamping the steel door body 13. Shaking may occur when the steel door body 13 is moved.

[0031] The electric telescopic cylinder 202, telescopic column 203, electric telescopic rod 3, buffer 10 and steel door body 13 in this application are all common electrical devices in the prior art, and their models or specific structures will not be described in detail in this application.

[0032] Working principle: First, the steel door body 13 is placed on the device. After the steel door body 13 is placed, the bottom surface of the steel door body 13 can be supported by the support column 9. Under the joint action of the spring 7 and the buffer 10, the limiting plate 8 and the support column 9 can be supported, thereby allowing the height of the steel door body 13 to be adjusted. Under the action of the electric telescopic rod 3, the clamping mechanism 2 can be rotated, making it easier for the steel door body 13 to be placed in the device. Then, the electric telescopic rod 3 drives the clamping mechanism 2 to reset. After the clamping mechanism 2 is reset, the electric telescopic cylinder 202 can push the telescopic column 203 to extend and retract. When the telescopic column 203 extends and retracts, it can drive the movable rods 204 on both sides to move. When the movable rods 204 on both sides move, the clamping frames 205 on both sides can clamp each other, thereby clamping the steel door body 13 and preventing the steel door body 13 from loosening during movement, thus achieving clamping of the steel door.
