[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] In this embodiment, to address the problem of industrial steel doors easily tipping over during installation and use, causing personal injury and property damage, the following technical solution is provided: Figure 1-6 As shown, an anti-tipping device for a swing door includes a top support 1 installed above the door frame 6 of the swing door. One side of the door leaf 3 is connected to the door frame 6 via multiple hinges 5. The top support 1 and the hinges 5 are vertically aligned. A horizontally rotatable connecting piece 16 is provided on the top support 1. A door leaf support 4 is installed on the upper part of the door leaf 3 on the side corresponding to the top support 1. A pull rod 2 has one end hinged to the connecting piece 16 and the other end hinged to the door leaf support 4. When the door leaf 3 with the door leaf support 4 is rotated open, the pull rod 2 and the connecting piece 16 rotate together with the door leaf 3. By providing a pull rod 2 and a connecting piece 16 that can rotate with the door leaf, the upper part of the door leaf always has a safety protection structure, thus preventing the door leaf from tipping over.

[0022] Specifically, the anti-tipping device in this embodiment needs to be installed before the swing door is installed. For example, first install the door frame 6 of the swing door, then install the top support 1 on the wall above the door frame 6, connect the upper end of the pull rod 2 to the connector 16, and then install the door leaf support 4 on the corresponding door leaf. At this time, the door leaf 3 is not yet connected to the door frame 6. Stand the door leaf 3 upright and connect the lower end of the pull rod 2 to the door leaf support 4. In this way, the upper part of the door leaf 3 forms a safety protection. Since both ends of the pull rod 2 are hinged, the door leaf 3 can move freely within a certain range. At this time, it is safer and more reliable to connect the door leaf 3 to the door frame through the hinge 5.

[0023] After the door leaf 3 is installed, the pull rod 2 remains connected to the door leaf support 4 and the top support 1. Since the connecting piece 16 can rotate horizontally, the pull rod 2 will not affect the normal opening and closing of the door leaf. Therefore, the anti-tipping device in this embodiment can play a safety protection role during the installation and use of the swing door, solving the safety problem that has been difficult to solve in the installation and use of industrial steel doors.

[0024] In this embodiment, as Figure 2 As shown, the top support 1 includes a first mounting pad 14 and an upper tie rod connecting seat 12 mounted on the first mounting pad 14. A support rotating shaft 17 is vertically passed through the middle of the upper tie rod connecting seat 12. The connecting member 16 is sleeved on the support rotating shaft 17. The structure is simple. The rotation of the connecting member 16 can be supported by the support rotating shaft 17, which is safe and reliable.

[0025] In this embodiment, as Figure 2-3 shown, the tie rod 2 includes an upper tie rod 22 and a lower tie rod 23. The upper tie rod 22 and the lower tie rod 23 are connected by an adjustable connecting sleeve 21. The upper end of the upper tie rod 22 is hinged to the connecting member 16, and the lower end of the lower tie rod 23 is hinged to the door leaf support 4. The length of the tie rod 2 can be adjusted according to the height of the door leaf 3, improving the versatility of the anti-overturning device. Specifically, by rotating the adjustable connecting sleeve 21, the upper tie rod 22 and the lower tie rod 23 can move axially relative to or towards each other, thereby adjusting the length of the entire tie rod 2.

[0026] In this embodiment, as Figure 3 shown, a pair of connecting plates 24 are arranged side by side at the upper end of the upper tie rod 22. A first connecting shaft 25 connected to the connecting member 16 is installed between the connecting plates 24. The connection is firm and has sufficient strength.

[0027] In this embodiment, the door leaf support 4 includes a second mounting pad 43 mounted on the door leaf and a lower tie rod connecting seat 41 mounted on the second mounting pad 43. The lower end of the tie rod 2 is connected to one side wall of the lower tie rod connecting seat 41 through a second connecting shaft 42. The structure is simple and the installation is convenient.

[0028] Among them, as Figure 2-6 shown, both the upper tie rod connecting seat 12 and the lower tie rod connecting seat 41 are in a "C" shape. The opening of the upper tie rod connecting seat 12 faces forward, and rotating shaft mounting holes 13 are provided on both its upper and lower side walls. The opening of the lower tie rod connecting seat 41 faces one side. The lower end of the tie rod 2 is connected to the front side wall of the lower tie rod connecting seat 41, facilitating the installation and connection of the support rotating shaft 17 and the first connecting shaft 42. The upper tie rod connecting seat 12 is welded to the first mounting pad 14, and the lower tie rod connecting seat 41 and the second mounting pad 43 are welded together. The connection is reliable and firm.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0030] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
