DETAILED DESCRIPTION

[0022] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Examples, such as Figure 1-Figure 4 As shown: The utility model provides a synchronous folding door that is easy to switch, and its structure includes two door leaves 1 and a connecting member 3 that allows the door leaves 1 to be swingably installed on a ground fixed body. The ground fixed body can be a brick wall, a column, a pile, or a door frame, an iron frame, an iron fence, etc. It is only necessary to keep the ground fixed body in a stable position, and the adjacent door leaf 1 in this embodiment is connected to the ground fixed body through a rotating shaft connecting member 3, and in this embodiment, the rotating shaft is vertically arranged and a motor-type driving member 4 is arranged at one end of the door leaf 1 along the rotating shaft to drive the door leaf 1 to actively move, and a hinge 2 is arranged between adjacent door leaves 1 to enable the two to swing relative to each other;

[0024] It should be noted that in this embodiment, the hinge 2 provided between the door leaves 1 is a two-way hinge or a double-opening hinge. Those skilled in the art will know that it includes a middle blade 21 and movable blades 22 connected by hinges on both sides. When closed, it is folded in a Z shape and connected to the door leaf 1 through the movable blades 22 on both sides, thereby allowing one door leaf 1 to move in two directions on another door leaf 1. When moving in different directions, different parts of the hinge parts of the three blades will be activated, which will not be elaborated here.

[0025] At the same time, a folding linkage 5 for making the two door leaves 1 move in linkage is provided between adjacent door leaves 1, so that the other door leaf 1 moves with the active door leaf 1 via the folding linkage 5, and after the motor drives the door leaf 1 to swing inward or outward to open actively, the other door leaf 1 swings inward or outward synchronously to overlap the active door leaf 1, and the folding linkage 5 includes a replaceable part, the replaceable part has two forms and corresponds to the inward folding or outward folding of the door leaf 1 respectively, and the unfolding and storage form of the inward folding or outward folding of the door leaf 1 can be changed by replacing the replaceable part;

[0026] To this end, the folding linkage 5 includes a first linkage 53 connecting the door leaves 1 on both sides, and the first linkage 53 is a replacement part. The first linkage 53 is a rod structure. The first linkage 53 is movably connected to the door leaves 1 on both sides. One end of the second linkage 55 is connected to the first linkage 53. The connection point between the first linkage 53 and the second linkage 55 is the third connection point. The other end of the second linkage 55 is connected to the ground fixed body connected to the door leaf 1. The door leaf 1 is provided with two sliding base members and includes a first sliding base member 51 and a second sliding base member 52. The first linkage 53 has two connection points and is divided into a first connection point and a second connection point in sequence. The first connection point and the second connection point are movably connected to the first sliding base member 51 and the second sliding base member 52 respectively. The two connection points of the first linkage 53 are rotatably connected with a movable slide 54, and the movable slide 54 is slidably connected to the first sliding base member 51 and the second sliding base member 52.

[0027] It should be noted that the movable range of the movable slide 54 on the first sliding base 51 and the second sliding base 52 is limited by the two ends of the first sliding base 51 and the second sliding base 52 to avoid overtravel;

[0028] Specifically, in this embodiment, the first sliding base member 51 and the second sliding base member 52 are slide rails, the movable slide member 54 is a slider, the slider is slidably engaged on the slide rail and retains the freedom to move along the length direction of the slide rail on the slide rail, and the first linkage member 53 is a rod structure, the two connection points on it are connected to the slider by a rotating shaft, and the slider retains the freedom to rotate around the rotating shaft, and the direction of the rotating shaft is vertical, so that a connecting rod slider mechanism is formed between the second linkage member 55 and the first door leaf 1, the first linkage member 53, and the second door leaf 1, thereby allowing the two replacement parts to achieve different guiding functions through the differentiated distribution of the position of the third connection point;

[0029] Subsequently, the first linkage 53 is a replacement part. In order to achieve the purpose of changing the inner and outer folding forms by replacing the first linkage 53, the control of the inner and outer folding is mainly concentrated on the first linkage 53, and it includes two forms to correspond to the two forms of the inner and outer folding, namely, the outer arm link 53a and the inner arm link 53b;

[0030] This embodiment includes an implementation in which the first linkage member 53 is an outer arm link 53a, the third connection point and the second connection point form the head and tail ends of the link structure, and the first connection point is located in the middle of the link structure, such as Figure 2 , Figure 3 As shown, the side connected with the second linkage member 55 is set as the inner side of the door, and the opposite side is the outer side of the door. When swinging, the motor drives the first door leaf 1 to swing inward, and the movable slide 54 on the first sliding base member 51 pushes against the end of the first sliding base member 51 close to the other door leaf 1, and is restricted from further sliding. At this time, the first door leaf 1, the first linkage member 53, and the second linkage member 55 form a quadrilateral connecting rod mechanism on the ground fixed body. Therefore, the angle between the door leaf 1 swinging inward and the ground fixed body becomes smaller and smaller, which will make the angle between the part of the first linkage member 53 connected to the second door leaf 1 and the first door leaf 1 smaller and smaller, so that the first linkage member 53 Component 53 drives the second sliding base component 52 and the second door leaf 1 to swing toward the first door leaf 1 through the movable slide 54, so that they are folded and fitted together. As the distance between the two door leaves 1 gradually approaches, and the position of the movable slide 54 on the first sliding base component 51 does not change much, the connection distance margin between the first linkage component 53 and the second door leaf 1 is offset by the movement of the movable slide 54 on the second sliding base component 52, thereby ensuring that the first linkage component 53 drives the second door leaf 1 to swing without interfering with the second door leaf 1 due to the gradual approach and fit of the distance between the two door leaves 1, thereby completing the function of the folding door when opening inwards.

[0031] On this basis, the first linkage member 53 is replaced so that the first linkage member 53 is an inner arm link 53b, the first connection point and the second connection point form the head and tail ends of the link structure, and the third connection point is located in the middle of the link structure, such as Figure 2 , Figure 4As shown, during the swinging, the motor drives the first door leaf 1 to swing outward, and the movable slide 54 on the first sliding base member 51 pushes against the end of the first sliding base member 51 away from the other door leaf 1, and is restricted from further sliding. At this time, the first door leaf 1, the first linkage member 53, and the second linkage member 55 form a quadrilateral linkage mechanism on the ground fixed body. Therefore, the angle between the door leaf 1 swinging outward and the ground fixed body becomes smaller and smaller, which makes the angle between the part of the first linkage member 53 connected to the second door leaf 1 and the first door leaf 1 smaller and smaller, so that the first linkage member 53 drives the second sliding base member 52 and the second door leaf 1 to the first door leaf through the movable slide 54. 1 direction, thereby folding and fitting, and as the distance between the two door leaves 1 gradually approaches, when the position of the movable slide 54 on the first sliding base member 51 does not change much, the connection distance margin between the first linkage member 53 and the second door leaf 1 is offset by the movable slide 54 moving on the second sliding base member 52, thereby ensuring that the first linkage member 53 will not interfere with the second door leaf 1 due to the gradual approach and fitting of the distance between the two door leaves 1 when the second linkage member 53 drives the second door leaf 1 to swing, thereby completing the function of the folding door when opening outwards, and thus achieving the function of allowing the folding door to change its opening direction on a hardware basis by replacing the first linkage member 53.

[0032] Furthermore, the present embodiment adapts to the range of the connecting rod mechanism before and after the replacement part is replaced, and the second connecting member 55 is a connecting rod whose length can be adjusted telescopically, or the part where the second connecting member 55 is connected to the ground fixed body is provided with a telescopically adjustable structure, or both;

[0033] In this embodiment, a second linkage member 55 is provided. At least one end of the second linkage member 55 is provided with a thread, and the portion connected to the external structure engages with the thread to adjust the length. For example, an internal thread is provided in the inner hole of the tubular structure, and then the portion connected to the external structure is in the shape of a bolt to cooperate with the internal thread so that the length can be adjusted by screwing in and out.

[0034] In this embodiment, a second linkage member 55 is provided. The second linkage member 55 is connected to the ground fixed body through a connecting frame protruding from the surface of the ground fixed body, and the connecting frame is provided with a rod member which is telescopically adjusted through a thread to be connected to one end of the second linkage member 55. The connecting frame is a C-shaped frame and the outer end is spaced apart from the surface of the ground fixed body. The portion connected to the second linkage member 55 is in the shape of a bolt to be threadedly matched with the connecting frame so that the length can be adjusted by screwing in and out.

[0035] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
