PREFERRED EMBODIMENT

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Example 1

[0024] In this embodiment, as Figures 1-5 As shown, an auxiliary tool for installing a security door includes a support crossbar 10. A second mounting hole is provided in the middle of the support crossbar 10, and a threaded rod 11 is threaded into the second mounting hole. An adjustment component 20 is provided at the bottom of the threaded rod 11 to facilitate adjusting the position of the door frame. The adjustment component 20 can firmly hook onto the door frame, facilitating subsequent adjustments. A rotating component 30 is provided at the top of the threaded rod 11 to adjust the distance between the door frame and the wall. By adjusting the rotating component 30, the device can be adapted to adjust door frames tilted at different distances from the wall, improving the applicability of the auxiliary tool for security door installation. Third mounting holes are provided at both ends of the support crossbar 10, and a fixing component 40 for leveling with the wall is provided at the third mounting hole. The fixing component 40 ensures that the support crossbar 10 is flush with the wall, eliminating the need for repeated adjustments after leveling. This allows for quick wall leveling during use, improving work efficiency.

[0025] Among them, such as Figures 1-3 As shown, the adjustment component 20 includes a fixing block 21, which is rotatably connected to the threaded rod 11. The fixing block 21 is connected to the bottom of the threaded rod 11 via a pressure bearing 24 to prevent the threaded rod 11 from rotating and causing the fixing block 21 to rotate. At the same time, the pressure bearing 24 reduces the resistance when the threaded rod 11 rotates, making it easier for workers to adjust the door frame angle. A first hook 22 and a second hook 23 are fixedly provided on the fixing block 21. The first hook 22 and the second hook 23 can contact the door frame of the security door, thereby hooking the door frame and making the installation operation more stable, ensuring that the auxiliary tool can hook the door frame.

[0026] Among them, such as Figures 1-3 As shown, the rotating assembly 30 includes a rotating rod 31. The top end of the threaded rod 11 has a first mounting hole 32. One end of the rotating rod 31 passes through the first mounting hole 32 and is fixedly connected to the threaded rod 11. The rotating rod 31 allows the threaded rod 11 to be rotated more effortlessly, making it easier to adjust the position of the security door frame.

[0027] Among them, such as Figure 1 , Figure 2 and Figure 4As shown, the fixing component 40 includes a bolt 41, which is threadedly connected to the support crossbar 10 through a third mounting hole. Rotating the bolt 41 can adjust the distance between the fixing plate 43 and the wall. A nut 42 is threaded onto the bolt 41, which can clamp the fixing plate 43 with the bolt 41, restricting the movement of the fixing plate 43 and facilitating disassembly and replacement. The fixing plate 43 is sleeved on the bolt 41 and is located below the nut 42. The fixing plate 43 can increase the contact area with the wall, making it easier to level the wall. Example 2

[0028] Among them, such as Figure 1 As shown, the rotating rod 31 is equipped with a handle for easy gripping, which facilitates the rotation of the threaded rod 11, thereby moving the security door and adjusting its position.

[0029] Among them, such as Figure 1 As shown, the support crossbar 10 has several openings 12, which can reduce the weight of the device itself, make it easier to use and carry, and increase its overall practicality.

[0030] Among them, such as Figure 1 As shown, two third mounting holes are symmetrically arranged on both sides of the second mounting hole to improve the stability of the device and facilitate the leveling of the wall surface.

[0031] Among them, such as Figure 1 As shown, bolt 41 is detachably connected to the third mounting hole. When not in use, bolt 41 can be removed for convenient storage and carrying.

[0032] In use, the worker holds the support bar 10 and hooks it onto the door frame to be adjusted using the first hook 22 and the second hook 23. Then, the worker rotates the bolt 41 to make the fixing plate 43 close to the wall. The worker continues to adjust the bolts 41 on both sides to ensure that the support bar 10 is flush with the wall. After leveling, no repeated adjustments are needed, which is convenient and quick. The worker only needs to hold the handle and rotate the rotating rod 31 to rotate the threaded rod 11, which in turn drives the fixing block 21 to hook the door frame and move it outward until it is flush with the wall. After the door frame is leveled, the worker does not need to support the door frame, which reduces the amount of labor and the probability of danger during the installation of the door frame.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
