Description

Technical Field

[0001] The utility model relates to the technical field of push-pull hangar doors, in particular to a push-pull hangar door anti-derailment structure and a push-pull hangar door. Background Art

[0002] Given the particularity of the height and area of ​​the hangar door, the wind pressure challenge it faces is particularly severe. Although the traditional sliding hangar door is equipped with a "wind-resistant column" to enhance its wind resistance, the non-rigid connection design between the lower profile of the hangar door leaf and the guide rail is particularly fragile in extreme weather. Under the action of strong winds, the hangar door leaf and the "wind-resistant column" are prone to significant deflection, forming an arc, which greatly increases the risk of the running wheel derailing, which not only affects the normal use of the hangar door, but also brings great inconvenience and cost to the subsequent maintenance work.

[0003] Therefore, it is necessary to develop a new push-pull hangar door anti-derail structure and a push-pull hangar door. Utility Model Content

[0004] The utility model aims to provide a push-pull hangar door anti-derailment structure and a push-pull hangar door, which can effectively reduce the deformation of the hangar door leaf in a strong wind environment to avoid the separation of the running wheel from the guide rail and the rigid deformation of the running wheel.

[0005] In the first aspect, the utility model provides a push-pull type hangar door anti-derailment structure, comprising:

[0006] The lower end profile of the door leaf is fixedly arranged at the lower end of the hangar door leaf;

[0007] An anti-slip limiter assembly, the upper end of which is fixedly mounted on the lower end profile of the door leaf, and the lower end of the anti-slip limiter assembly is provided with a limit opening, which is used to form a stable connection with the guide rail;

[0008] The guide rail is installed in the outer frame of the hangar door. The upper end of the guide rail is provided with a step, which extends into and is locked in the limit opening.

[0009] Optionally, the anti-drop limit assembly includes two oppositely arranged pull hooks, each of which is J-shaped as a whole, and its upper end is fixedly mounted on the lower end profile of the door leaf, and the lower end of the pull hook has a pair of hooks protruding toward the guide rail side, and the hooks of the two pull hooks together form the limit opening, and the hooks are hung on the lower edge of the step and tightly against the two sides of the guide rail, so as to prevent the hangar door leaf from derailing in strong winds or abnormal conditions.

[0010] Optionally, the upper end of the draw hook is fixedly mounted on the lower end profile of the door leaf through a mounting block, the mounting block is provided with two mounting notches, and the upper ends of the two draw hooks are respectively inserted into the two mounting notches and locked and fixed on the mounting block. The fixed mounting method between the draw hook and the mounting block has the advantages of stable structure, convenient installation, easy maintenance, strong adaptability and high safety.

[0011] Optionally, the fixing mode between the mounting block and the lower end profile of the door leaf is a detachable connection, so as to facilitate the installation, maintenance or replacement of the anti-drop limit assembly.

[0012] Optionally, the hook surface of the pull hook is made of wear-resistant material to increase its service life and reduce friction and wear between the pull hook and the guide rail.

[0013] In a second aspect, a push-pull type hangar door described in the utility model adopts the push-pull type hangar door anti-derailment structure described in the utility model.

[0014] The beneficial effects of the utility model are as follows: without increasing the thickness and strength of the hangar door leaf and the "wind-resistant column" material, the utility model adds an anti-slip limit assembly at the lower end of the sliding hangar door. This can effectively reduce the deformation of the hangar door leaf in a strong wind environment, avoid the detachment of the walking wheels from the guide rails, and prevent the walking wheels from producing rigid deformation, without affecting other performances of the sliding hangar door.

The upper end of the anti-slip limit assembly is fixedly mounted on the door leaf lower end profile 1, and the lower end of the anti-slip limit assembly is provided with a limit opening, which is used to form a stable connection with the guide rail 4. The guide rail 4 is installed in the outer frame 5 of the hangar door, and the upper end of the guide rail 4 has a step 41, which extends into and locks in the limit opening.

[0019] like Figure 1 As shown, in a possible embodiment, the anti-dropping limit assembly includes two oppositely arranged pull hooks 6, each pull hook 6 is J-shaped as a whole, and its upper end is fixedly mounted on the lower end profile 1 of the door leaf, and the lower end of the pull hook 6 has a pair of hooks protruding toward the side of the guide rail 4, and the hooks of the two pull hooks 6 together form a limit opening, and the hooks are hung on the lower edge of the step and tightly against the two sides of the guide rail 4. This prevents the hangar door leaf 2 from derailing in strong winds or abnormal conditions.

[0020] like Figure 2 As shown, in a possible embodiment, the upper end of the hook 6 is fixedly mounted on the lower end profile 1 of the door leaf through the mounting block 3, and two mounting notches 31 are provided on the mounting block 3. The upper ends of the two hooks 6 are respectively inserted into the two mounting notches 31 in a one-to-one correspondence and locked and fixed on the mounting block 3. The fixed installation method between the hook 6 and the mounting block 3 has the advantages of stable structure, convenient installation, easy maintenance, strong adaptability and high safety.
