[0020] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0021] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0023] An embodiment of this utility model provides a sliding door with a sealing structure, such as... Figure 1-4 As shown, the system includes a left sliding door unit 101 and a right sliding door unit 102. Both the left and right sliding door units 101 and 102 include door leaves 2 and a composite door frame 103 disposed on the outside of the door leaves 2. Each unit of the left and right sliding door units 101 and 102 contains one or more door leaves 2, and each door leaf 2 has a composite door frame 103 on its outside. In this embodiment, the composite door frame 103 mainly refers to the outermost composite door frame 103 of each unit. A first sealing structure 104 is provided between the composite door frame 103 on the right side of the left sliding door unit 101 and the composite door frame 103 on the left side of the right sliding door unit 102. When the left and right sliding door units 101 and 102 are closed, the composite door frames 103 between the two units are interconnected, and the first sealing structure 104 provides a good seal between them. The left sliding door unit 101 and the right sliding door unit 102 are equipped with a composite frame 4 fixed to the wall on their outer sides. The composite frame 4 includes composite vertical frames 401 located on its left and right sides. Since the left sliding door unit 101 and the right sliding door unit 102 are sliding door structures that can slide left and right, a composite frame 4 is provided on the outer side of the whole. The composite door leaf frames 103 on the outer side of the two units are connected to the composite frame 4. A second sealing structure 105 is provided between the composite door leaf frame 103 on the left side of the left sliding door unit 101 and the composite vertical frame 401, and between the composite door leaf frame 103 on the right side of the right sliding door unit 102 and the composite vertical frame 401. The second sealing structure 105 can provide a good sealing effect when the two units are closed with the composite vertical frame 401, preventing air leakage. The sealing structure of this sliding door is simple and has a good sealing effect.

[0024] In some embodiments, such as Figure 1-2As shown, the composite door frame 103 includes a first side frame strip 106 and a second side frame strip 107 connected to each other. A first groove 108 is formed between the first side frame strip 106 and the second side frame strip 107. A first fixing groove 110 is provided opposite to each other on one side of the first groove 108. A sealing strip 111 is provided in the first fixing groove 110. Specifically, the first side frame strip 106 and the second side frame strip 107 are connected by a heat insulation strip. The composite door frame 103 is actually connected to the outside of the door leaf 2. The first fixing groove 110 is opposite to each other. The sealing strip 111 provided in the groove allows the sliding door to form a good seal with other structures when closed in the middle or on both sides.

[0025] Furthermore, such as Figure 1-2 As shown, the first sealing structure 104 includes a door leaf joint strip 112 that is engaged on the composite door leaf frame 103 on the right side of the left sliding door unit 101, and a sealing strip 111 on the composite door leaf frame 103 on the left side of the right sliding door unit 102, which is a first sealing strip 113. When the left sliding door unit 101 and the right sliding door unit 102 are closed, the first sealing strip 113 abuts against the door leaf joint strip 112. Since the left sliding door unit 101 and the right sliding door unit 102 are in contact through the composite door leaf frame 103, the door leaf joint strip 112 added on the composite door leaf frame 103 on the right side of the left sliding door unit 101 allows the first sealing strip 113 in the first groove 108 of the composite door leaf frame 103 on the left side of the right sliding door unit 102 to abut against the door leaf joint strip 112 when the frame is closed, forming a sealed space.

[0026] Furthermore, such as Figure 1-2As shown, the door panel joint strip 112 includes a first inner frame strip 114 protruding to the right and a second inner frame strip 115 disposed on both sides of the first inner frame strip 114. A second fixing groove 116 is formed between the first inner frame strip 114 and the second inner frame strip 115. A second sealing strip 117 is provided in the second fixing groove 116. When the left sliding door unit 101 and the right sliding door unit 102 are closed, the first sealing strip 113 abuts against the first inner frame strip 114, and the first side frame strip 106 and the second side frame strip 107 of the right sliding door unit 102 abut against the second sealing strip 117. Specifically, the first inner frame strip 114 is a protruding frame strip with a cavity. The whole can be a split type as in this embodiment, which facilitates the installation of the door lock structure. The first inner frame strip can also be a one-piece piece, and its side wall is directly used for sliding and sealing with the first sealing strip 113. The second inner frame strip 115 is disposed on both outer sides of the first inner frame strip 114, and the second sealing strip 117 is placed in the second fixing groove 116 formed between them. When the left sliding door unit 101 and the right sliding door unit 102 are closed, the ends of the first side frame strip 106 and the second side frame strip 107 on the right sliding door unit 102 abut against the second sealing strip 117, which has the function of buffering impact and further sealing.

[0027] Furthermore, such as Figure 1-2 As shown, the door panel joint strip 112 also includes a third inner frame strip 118 extending above the first fixing groove 110 on the left sliding door unit 101, and the sealing strip 111 on the composite door frame 103 on the right side of the left sliding door unit 101 is a third sealing strip 119. The third inner frame strip 118 allows the door panel joint strip 112 to be snapped onto the composite door frame 103 on the right side of the left sliding door unit 101, facilitating the closing of the left sliding door unit 101 and the right sliding door unit 102. The third sealing strip 119 makes the door panel joint strip 112 more stable and enhances the sealing of the joint of the door panel joint strip 112.

[0028] Furthermore, such as Figure 1-2 As shown, the third sealing strip 119 includes a fixing part 120 fixed in the first fixing groove 110, a V-shaped strip 121 that abuts against the third inner frame strip 118, and a corner strip 122 connected to one right end of the V-shaped strip 121. The corner strip 122 is inserted into the gap formed between the outside of the first fixing groove 110 and the door panel joint strip 112. The V-shaped strip 121 can seal both the third inner frame strip 118 and the upper side of the first fixing groove 110, and can also seal the gap outside the first fixing groove 110 through the extension of the corner strip 122, thus improving the sealing performance.

[0029] Furthermore, such as Figure 1 , 3As shown, the second sealing structure 105 includes a fourth inner frame strip 123 extending towards the composite door frame 103 from the composite vertical frame 401, and a fifth inner frame strip 124 on one side of the fourth inner frame strip 123. A third fixing groove 125 is formed between the fourth inner frame strip 123 and the fifth inner frame strip 124. A second sealing strip 117 is provided in the third fixing groove 125. The sealing strip 111 on the composite door frame 103 is the first sealing strip 113. When the left sliding door unit 101 or the right sliding door unit 102 is closed with the composite vertical frame 401, the first sealing strip 113 abuts against the fourth inner frame strip 123, and the second frame strip 107 abuts against the second sealing strip 117. Because the second sealing structures 105 on the left and right sides are symmetrically arranged, Figure 3 Only one side is shown. Specifically, the second sealing structure 105 is used to seal between the composite vertical frame 401 and the left and right sliding door units 102. Since each of the composite door leaf frames 103 of the left and right sliding door units 102 is provided with a corresponding first sealing strip 113, the composite vertical frame 401 is also provided with a fourth inner frame strip 123 to slide and seal with the first sealing strip 113. The fourth inner frame strip 123 is a protruding frame strip with a cavity. The whole can be a split type as in this embodiment, which facilitates the installation of the door lock structure. The fourth inner frame strip 123 can also be an integral piece. Since the sliding door on one side of the composite vertical frame 401 opens and closes relatively less, the fifth inner frame strip 124 is only set on the outer side to reduce costs. The second frame strip 107 abuts against the second sealing strip 117 therein, which has the function of buffering impact and further sealing.

[0030] Furthermore, such as Figure 1 , 4 As shown, the composite frame 4 includes a composite upper sliding frame 402 located on its upper side. A sixth inner frame strip 403 is provided on the lower side of the composite upper sliding frame 402. The sixth inner frame strip 403 abuts against the sealing strips 111 on the composite door leaf frames 103 on the upper sides of both the left and right sliding door units 101 and 102. The sealing strips 111 on the composite door leaf frames 103 on the upper sides of both the left and right sliding door units 101 and 102 are first sealing strips 113. The upper sides of both the left and right sliding door units 101 and 102 are slidably sealed with the composite frame 4 by the first sealing strip 113, improving the overall sealing performance of the sliding doors.

[0031] Furthermore, such as Figure 1 , 4As shown, the composite frame 4 includes a composite sliding frame 404 located on its lower side. A seventh inner frame strip 405 is provided on the upper side of the composite sliding frame 404. A third groove 407 for placing the pulley assembly 406 is provided in the middle of the seventh inner frame strip 405. The seventh inner frame strip 405 abuts against the sealing strips 111 on the composite door leaf frames 103 on the lower sides of both the left sliding door unit 101 and the right sliding door unit 102. The sealing strips 111 on the composite door leaf frames 103 on the upper sides of both the left sliding door unit 101 and the right sliding door unit 102 are first sealing strips 113. The lower sides of both the left sliding door unit 101 and the right sliding door unit 102 are slidably sealed with the composite frame 4 by the first sealing strip 113, improving the overall sealing performance of the sliding door without affecting the movement of the pulley assembly 406.
