[0030] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0031] Example 1: See Figures 1 to 5 As shown, a double-leaf soundproof linkage door installation structure comprises a door frame 1, an inner door 2 and an outer door 3 are installed on the door frame 1, one end of the inner door 2 and the outer door 3 are hingedly connected to one side of the door frame 1, and the inner door 2 is arranged on the inner side of the outer door 3;

[0032] A linkage device 4 is also provided between the inner door 2 and the outer door 3, and the two ends of the linkage device 4 are respectively connected to the inner door 2 and the outer door 3;

[0033] When the inner door 2 is opened or closed, the outer door 3 is driven to open or close synchronously via the linkage device 4;

[0034] When the outer door 3 is opened or closed, the inner door 2 is driven to open or close synchronously via the linkage device 4 .

[0035] In this embodiment, the door frame is installed on the soundproof room, and the middle part of the door frame is a door opening for users to enter and exit. When the inner and outer doors are closed, the door opening is closed, and the user cannot enter and exit from the door opening of the door frame. When the inner and outer doors are opened, the door opening is opened, and the user can enter and exit from the door opening of the door frame. Among them, the inner door and the outer door are set, and there is a certain distance between the inner door and the outer door, so that when the inner and outer doors are opened and closed, the inner and outer doors are given a rotation space to prevent collision and jamming, and ensure that the inner and outer doors can be opened and closed normally and smoothly. Among them, in order to improve the convenience of use, the user only needs to perform one action when opening or closing the door, and a linkage device is set between the inner door and the outer door. In this way, when closing or opening the door, only the inner door or the outer door needs to be grasped to open and close, and the other door can be synchronously driven to follow the action through the linkage device, thereby improving the convenience of use for the user, and there is no need to perform two door opening actions or two door closing actions in sequence each time the door is opened or closed.

[0036] Furthermore, in order to reduce the space occupied, the inner door and the outer door have the same opening direction, and the inner door and the outer door have the same closing direction. Conventional doors all have the mode of opening inward or opening outward. The mode of opening inward is to rotate the door panel (the inner door and the outer door in this embodiment) toward the inside of the door opening, and the mode of opening outward is to rotate the door panel toward the outside of the door opening to open. In the prior art, the conventional double-door structure generally has the following door opening modes: the outer door has an outward door opening structure, and the inner door has an inward door opening structure. In this embodiment, the inner door and the outer door are both outward door opening structures, that is, when the inner door and the outer door are opened, they are rotated toward the outside of the door opening to realize the door opening action.

[0037] See also Figure 2 , 3 As shown, the linkage device 4 includes an inner door reinforcement rib 5, an outer door reinforcement rib 6 and a middle connecting piece. The inner door reinforcement rib 5 is installed on the outer side of the inner door 2, and the outer door reinforcement rib 6 is installed on the inner side of the outer door 3. The two sides of the middle connecting piece are respectively connected to the inner door reinforcement rib 5 and the outer door reinforcement rib 6.

[0038] In this embodiment, the inner door reinforcement ribs and the outer door reinforcement ribs are used to connect the middle connecting piece with the inner door and the outer door. This can prevent the middle connecting piece from directly damaging the inner door and the outer door during the opening and closing process of the inner and outer doors, thereby reducing the maintenance rate and ensuring the sound insulation quality.

[0039] See also Figures 2 to 4As shown, the middle connecting member includes a slide rail 7, a slider 8 and a connecting member 9. The slide rail 7 is installed on the inner door reinforcement rib 5 or the outer door reinforcement rib 6. One end of the connecting member 9 is rotatably connected to the slider 8, and the other end of the connecting member 9 is fixedly connected to the outer door reinforcement rib 6 or the inner door reinforcement rib 5. The slider 8 is slidably connected to the slide rail 7.

[0040] In the present invention, there are two ways of connecting the middle connecting member: the first way: the slide rail 7 is fixedly connected to the outer door reinforcement rib 6, one end of the connecting member 9 is fixedly connected to the inner door reinforcement rib 5, and the other end is rotatably connected or hinged to the slider 8, and the slider 8 is slidably connected to the slide rail 7. That is, the slide rail is connected to the outer door reinforcement rib, and the connecting member is respectively connected to the inner door reinforcement rib and the slider.

[0041] The second type: the slide rail 7 is fixedly connected to the inner door reinforcement rib 5, one end of the connector 9 is fixedly connected to the outer door reinforcement rib 6, and the other end is rotatably connected or hinged to the slider 8, and the slider 8 is slidably connected to the slide rail 7. That is, the slide rail is connected to the inner door reinforcement rib, and the two ends of the connector are respectively connected to the outer door reinforcement rib and the slider. In this embodiment, the connector is a connecting hinge.

[0042] There are two possible connection modes for the middle connecting member. In this embodiment and the accompanying drawings, the first mode is taken as an example, that is, the slide rail and the outer door reinforcement rib are connected. In this embodiment, the left side of the inner door and the outer door are hinged to the door frame.

[0043] The slide rail may be a T-shaped slide rail, and the slider has a T-shaped slide groove, so that the slider can only move relative to the slide rail, and the slider cannot move away from the slide rail, thereby preventing the slider from detaching from the slide rail. Alternatively, a slide groove is provided on the slide rail, and one end of the slider is slidably connected to the slide groove, and the slide groove is used to limit the slider from detaching from the slide rail. Alternatively, a slide groove is provided on the slider, and the inner end of the slide rail is slidably connected to the slide groove of the slider, and the slide groove is used to limit the slider from detaching from the slide rail.

[0044] When the inner and outer doors are opened and closed, taking the case where the operator stands outside the outer door to open the door as an example, the right end of the outer door is pulled outward by a pulling force, which will drive the right end of the outer door to move outward, that is, the left end of the outer door rotates around the door frame. In the process of the right end of the outer door moving outward, the slide rail will also move outward away from the door frame. When the slider moves, it will simultaneously give the slider an outward pulling force, and synchronously drive the slider to move outward following the slide rail. Since the left end of the inner door is hinged to the door frame, when the inner door is opened, the relative lateral positions of the inner door reinforcement ribs connected to the connecting piece and the slide rail will change, and the inner door reinforcement ribs will move to the left relative to the slider. Therefore, the slider and the slide rail are slidably connected. In the process of opening the outer door, the slider will move to the left along the slide rail. Since the two ends of the connecting piece are respectively connected to the slider and the inner door reinforcement rib (one end of the connecting piece is fixedly installed on the inner door reinforcement rib, and the other end is rotatably connected or hinged to the slider), an outward pulling force will be given to the inner door through the slider and the connecting piece, thereby pulling the inner door to rotate at the same time. When closing the door, if the outer door is used to push the door, since the connection position of the connecting piece and the inner door reinforcement rib is fixed, when the slide rail moves inward, it will push the inner door through the slider and the connecting piece, so that the inner door will also follow the closing of the door. When the inner door moves inward, it will pull the slider through the connecting piece. Due to the change in the position of the inner door and the outer door, the inner door reinforcement rib moves to the right relative to the outer door reinforcement rib, so the slider will also move to the right along the slide rail, thereby achieving synchronous closing of the door. Similarly, whether the door is opened from the inside of the inner door or closed from the outside of the outer door, the slider will move left and right on the slide rail to achieve synchronous opening and closing of the inner door and the outer door. Among them, limit stops can also be set on both sides of the slide rail to limit the movement of the slider on the slide rail to prevent the slider from detaching from the slide rail (in this embodiment, there is no need to set limit stops, because one end of the connecting piece is fixedly connected to the inner door reinforcement rib. When opening and closing the door, the relative displacement distance between the inner door reinforcement rib and the outer door reinforcement rib is short and will not exceed the limit of the movement distance of the slider on the slider). At the same time, the two ends of the connecting piece are respectively fixedly connected to the inner door reinforcement ribs and rotatably connected to the slider, which can ensure that the position and angle between the slider and the inner door are adjusted during the rotation of the inner door and the movement of the slider, thereby ensuring the normal rotation and opening and closing of the inner door and the outer door.

[0045] See also Figure 5 As shown, an inner magnetic sealing strip 10 is provided at the outer edge of the inner end surface of the inner door 2;

[0046] An outer magnetic sealing strip 11 is provided at the outer edge of the inner end surface of the outer door 3; wherein, in this embodiment, the width and height of the outer door are greater than the width and height of the inner door.

[0047] When the inner door 2 and the outer door 3 are in a closed state, the inner magnetic sealing strip 10 and the outer magnetic sealing strip 11 are respectively attached to the door frame 1 .

[0048] By providing an inner magnetic sealing strip and an outer magnetic sealing strip, when the door is closed, the inner magnetic sealing strip and the outer magnetic sealing strip will fit tightly against the door frame, so that there is no gap at the contact between the door frame and the inner and outer doors, and no sound leakage occurs, thereby ensuring the sound insulation effect. Moreover, it is double sound insulation, and the sound insulation effect is stronger.

[0049] See also Figure 5 As shown, the door frame 1 is provided with an inner frame surface 12 and an outer frame surface 13, the inner frame surface 12 is arranged on the inner side of the outer frame surface 13, and when the inner door 2 and the outer door 3 are closed, the inner magnetic sealing strip 10 is attached to the inner frame surface 12, and the outer magnetic sealing strip 11 is attached to the outer frame surface 13. The arrangement of the inner frame surface and the outer frame surface enables the inner magnetic sealing strip and the outer magnetic sealing strip to be attached to the inner frame surface and the outer frame surface of the door frame respectively, thereby ensuring the sealing effect.

[0050] In order to facilitate the opening and closing of the inner door and the outer door, an inner handle 14 is provided on the inner end surface of the inner door 2. An outer handle is provided on the outer end surface of the outer door. With the existence of the inner handle and the outer handle, the operator can directly grasp the corresponding handle when opening and closing the inner door and the outer door, thereby improving the convenience of operation.
