Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only to represent selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. EMBODIMENT

[0037] In conjunction with Figures 1 to 12 , the present embodiment provides a door limit sliding support for fixing the angle of opening the door, comprising a first swing arm 1, a second swing arm 2 and a limiting structure, wherein the first swing arm 1 and the second swing arm 2 are hingedly arranged and are respectively connected with a door frame 4 and a door body 5, the limiting structure comprises a limiting part 31, a locking piece 32 and an elastic piece 33, the limiting part 31 is installed or formed on one of the swing arms, the locking piece 32 is arranged on the other swing arm and abuts against the elastic piece 33, the locking piece 32 is configured to be clamped with the limiting part 31 when the door body 5 is opened, so as to correspondingly lock the first swing arm 1 and the second swing arm 2, and the locking piece 32 can be driven away from the limiting part 31 in an operable manner to unlock the first swing arm 1 and the second swing arm 2.

[0038] Exemplarily, the door body 5 and the door frame 4 are hingedly connected by hinges, and a first connecting member 11 is hingedly provided on the first swing arm 1, and the first connecting member 11 is used to be fixedly connected to the door frame 4, and a second connecting member 21 is hingedly provided on the second swing arm 2, and the second connecting member 21 is used to be fixedly connected to the door body 5. Preferably, the installation directions of the first connecting member 11 and the second connecting member 21 are perpendicular. The first connecting member 11 is installed on the top of the door frame 4, and the second connecting member 21 is installed on the back of the door body 5, so that the door body 5 can be opened and closed in a horizontal direction. In one embodiment, a fixing member 41 for connecting to the first connecting member 11 can be welded or installed on the top of the door frame 4, and the fixing member 41 protrudes from the door frame 4, which can reduce the space occupied by the threshold sliding support structure on the door frame 4, which is conducive to the application in the aftermarket. Among them, the first connecting member 11 and the second connecting member 21 can be fixed to the door frame 4 and the door body 5 by screws or bolts.

[0039] It should be noted that in this embodiment, by providing a threshold sliding support structure, when the door is opened, the door body 5 drives the swing arm to swing, so that the limiting portion 31 located on one of the swing arms engages with the locking member 32 located on the other swing arm, thereby locking the first swing arm 1 and the second swing arm 2, so that the door body 5 is fixed at the current angle. Among them, the elastic member 33 is arranged in contact with the locking member 32 to ensure the locking force and the reliability of the locked state, prevent the door body 5 from being closed by strong winds or misoperation, and prevent the door body 5 from automatically closing and colliding with a human body or object. When closing the door, it is sufficient to drive the locking member 32 away from the limiting portion 31. The structure is simple and the operation is convenient. It is easy to understand that the angle of the door body 5 can be fixed while the door is opened, which is convenient for the user. In addition, the threshold sliding support structure is installed between the door body 5 and the door frame 4, which can avoid damage to the ground or wall and is also convenient for cleaning.

[0040] In a preferred embodiment, a stopper 31 is formed at one end of the first swing arm 1 and is recessed. A guide surface 311 is angled along one sidewall of the recess. Second swing arms 2 are positioned on either side of the first swing arm 1, forming an installation space between the two second swing arms 2 for mounting the locking member 32. An assembly block 34 is positioned within the installation space, having a mounting groove. An elastic member 33 is received within the groove and abuts against the locking member 32. A movable groove 22 is defined in the second swing arm 2, and the locking member 32 is provided with a toggle portion 321. The toggle portion 321 extends through the movable groove 22 and protrudes outward from the second swing arm 2. For example, the first swing arm 1 and the two second swing arms 2 are hingedly connected by a rotating shaft 6, which can be a bolt or a pin. When the door is opened, the door body 5 drives the second swing arms 2 to swing toward the stopper 31, allowing the locking member 32 to slide along the guide surface 311 into the stopper 31. The inclined guide surface 311 ensures smooth entry of the locking member 32. The width of the groove is set to match the locking member 32 to prevent the locking member 32 from shaking. Specifically, the guide surface 311 abuts the locking member 32 to compress the elastic member 33 (preferably a spring) so that the locking member 32 can slide into the groove and engage and lock. When closing the door, the user applies force to the toggle portion 321 to slide the locking member 32 along the movable groove 22, which causes the locking member 32 to disengage from the groove. At this time, the first swing arm 1 and the second swing arm 2 are unlocked, and the door body 5 can rotate freely to close the door. After the user releases the locking member 32, the locking member 32 is reset under the action of the elastic member 33 to prepare for the next door opening. In this embodiment, the parts for opening the door on the left and the right are the same, and they only need to be distinguished during installation, thereby reducing the cost of parts.

[0041] Preferably, the locking member 32 further includes a positioning portion 322, a guide portion 323, a locking portion 324, and an abutting portion 325. The positioning portion 322 is used to abut against the assembly block 34 for limiting position, the guide portion 323 is inserted into the movable groove 22, the locking portion 324 is used to engage with the limiting portion 31 for limiting position, and the abutting portion 325 is used to abut against the elastic member 33. The guide portions 323 at the top and bottom of the locking member 32 are both inserted into the movable groove 22. On the one hand, they can cooperate with the elastic member 33 to play a limiting role, and on the other hand, they can ensure the smooth movement of the locking member 32, ensuring smooth opening and closing of the door. In one embodiment, the locking member 32 is arranged in a cross shape, but this is not limited to this and is not specifically limited.

[0042] On the basis of the above-mentioned embodiments, in an optional embodiment of the utility model, the rope hole 3211 is arranged on the dialing part 321, the fixed pulley 23 is arranged on the outer wall surface of the second swing arm 2, and the pull rope passes through the rope hole 3211 and hangs down along the fixed pulley 23. The user can pull down the pull rope to drive the dialing part 321 to move, thereby driving the locking part 32 to move synchronously, and realizing the unlocking of the first swing arm 1 and the second swing arm 2. The setting of the pull rope can facilitate the user operation, avoid the problem that the dialing part 321 is too high and inconvenient to operate. The end of the pull rope is provided with a counterweight, so that the pull rope can keep the vertical state. The fixed pulley 23 is arranged in the shell 24, the inlet is arranged on the shell 24, the pull rope passes into the inlet, and is arranged around the groove on the fixed pulley 23, wherein the inner wall of the shell 24 can limit the pull rope, avoiding the pull rope from sliding out of the groove on the fixed pulley 23.

[0043] The above are only preferred embodiments of the utility model, the protection scope of the utility model is not only limited to the above-mentioned embodiments, and all technical schemes under the idea of the utility model belong to the protection scope of the utility model.
