Description

Technical Field

[0001] The utility model relates to a door and window sealing device, in particular to a pressing type door and window sealing device. Background Art

[0002] The existing door and window structure includes a frame body and a door body (window body) connected to the frame body. In order to enable the door body (window body) to be smoothly installed into the frame body, the size of the door body (window body) is slightly smaller than the inner hole size of the frame body. Since the size of the door body (window body) is slightly smaller than the inner hole size of the frame body, there is a certain gap between the door body (window body) and the frame body when the door body (window body) is closed, resulting in poor sealing performance and sound insulation effect when the door body (window body) is closed. Content of the Utility Model

[0003] The purpose of the utility model is to provide a pressing type door and window sealing device to solve the problem that there is a gap between the door body (window body) and the frame body (or bottom surface) when the existing door body (window body) is closed, resulting in poor sealing performance and sound insulation effect when the door body (window body) is closed.

[0004] The utility model is realized through the following technical solutions:

[0005] A pressing type door and window sealing device includes a housing, a driving member, a telescopic member and a sealing member. The driving member can move forward and backward along the housing to extend out of or retract into the housing. The sealing member can move up and down along the housing to extend out of or retract into the housing. The telescopic member is respectively rotatably connected to the driving member and the sealing member, so that the sealing member moves downward and extends out of the housing when the driving member moves and retracts into the housing, or the sealing member moves upward and retracts into the housing when the driving member moves and extends out of the housing.

[0006] Further, the housing has an assembly cavity, a side through port and a lower through port. The driving member, the telescopic member and the sealing member are accommodated in the assembly cavity. The side through port allows the driving member to extend out of or retract into the housing when moving forward and backward. The lower through port allows the sealing member to extend out of or retract into the housing when moving up and down.

[0007] Further, a reset elastic member is disposed through one end of the driving member away from the side through port. The reset elastic member abuts against the driving member and the housing respectively to make the driving member move in the direction of the side through port and extend out of the housing.

[0008] Further, a buffer elastic member is disposed through one end of the driving member adjacent to the side through port. The buffer elastic member makes the driving member have a movement tendency to move in the direction of the side through port.

[0009] Further, the driving member includes a linkage rod, a pushing member, and a locking member. The linkage rod is slidably connected to the housing and can move back and forth along the housing. The pushing member is movably connected to the linkage rod and can move back and forth relative to the linkage rod. The locking member is inserted through the pushing member to lock and fix the pushing member on the linkage rod.

[0010] Further, the linkage rod has a threaded hole for the pushing member to insert. The pushing member is threadedly connected to the linkage rod in the threaded hole. The locking member includes a nut threadedly connected to the linkage rod and a snap ring provided on one side of the nut.

[0011] Further, the driving member has a transverse guide hole extending in the front-rear direction, and the housing has a transverse guide post slidably engaged with the transverse guide hole; and / or the sealing member has a vertical guide hole extending in the up-down direction, and the housing has a vertical guide post slidably engaged with the vertical guide hole.

[0012] Further, the sealing member includes a base and a sealing strip. The base is slidably connected to the housing and can move up and down along the housing. The sealing strip is detachably and fixedly connected to one side of the base opposite to the lower through port.

[0013] Further, the housing has a positioning hole opposite to the side through port in the front-rear direction. The positioning hole is for the end of the driving member away from the side through port to insert.

[0014] Further, the housing is in a shape of a capital "J"; or the housing has a U-shaped portion and an outer connecting portion provided above the U-shaped portion. A connecting hole is formed on the outer connecting portion. The driving member and the sealing member are slidably connected to the U-shaped portion.

[0015] The advantages of this technical solution are as follows: By configuring the door and window pressing type sealing device into a housing, a driving member, a telescopic member, and a sealing member, the telescopic member is rotatably connected to the driving member and the sealing member respectively, so that when the driving member moves and retracts into the housing, the sealing member moves downward and extends out of the housing, or when the driving member moves and extends out of the housing, the sealing member moves upward and retracts into the housing. Therefore, when the door and window pressing type sealing device is applied to doors and windows, by opening and closing the doors and windows (door body or window body), the frame body (door frame or window frame) can press the driving member into the housing, causing the sealing member to move out of the housing to fill the gap, or the frame body releases the driving member to make the sealing member reset and retract into the housing. While improving the sealing performance / noise insulation performance of the door and window structure, it avoids the wear caused by the long-term exposure of the sealing member and the friction with the frame body.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0028] Example 1: As Figures 1-6 shown, the push-type sealing device for doors and windows includes a housing 1, a driving member 2, a telescopic member 3, and a sealing member 4. The driving member 2 can move back and forth relative to the housing 1 to extend out of or retract into the housing 1. The sealing member 4 can move up and down relative to the housing 1 to extend out of or retract into the housing 1. The telescopic member 3 is rotatably connected to the driving member 2 and the sealing member 4 respectively, so that the sealing member 4 moves downwards and extends out of the housing 1 when the driving member 2 moves and retracts into the housing 1, or the sealing member 4 moves upwards and retracts into the housing 1 when the driving member 2 moves and extends out of the housing 1.

[0029] Among them, the driving member 2 retracting into the housing 1 should be understood as the driving member 2 completely retracting into the housing 1 or partially retracting into the housing 1, and the driving member 2 extending out of the housing 1 should be understood as the driving member 2 partially extending out of the housing 1.

[0030] Among them, the sealing member 4 extending out of the housing 1 should be understood as the sealing member 4 partially extending out of the housing 1 or completely extending out of the housing 1, and the sealing member 4 retracting into the housing 1 should be understood as the sealing member 4 partially retracting into the housing 1 or completely retracting into the housing 1.

[0031] As Figure 6 shown, when the push-type sealing device 100 for doors and windows is applied to the door body 200, the housing 1 is assembled on the frame of the door body 200, and the side of the housing 1 where the sealing member 4 extends is opposite to the door frame 300 (i.e., the driving member 2 is opposite to the door frame 300). When the door body 200 is closed, the distance between the door body 200 and the door frame 300 is narrowed, so that the driving member 2 that moves close to the door frame 300 along with the door body 200 is pushed into the housing 1 by the door frame 300, thereby driving the sealing member 4 to extend out of the housing 1 and abut against the door frame 300 (or the ground), filling the gap between the door body 200 and the door frame 300 or filling the gap between the door body 200 and the ground, improving the sealing performance and sound insulation of the door body structure; when the door body 200 is opened, the distance between the door body 200 and the door frame 300 is increased to release the driving member 2, so that the sealing member 4 is reset and retracted into the housing 1 and separated from the door frame 300 (or the ground), avoiding wear caused by long-term exposure. In summary, when the push-type sealing device 100 for doors and windows is applied to the door body 200, by using the change in the distance between the door body 200 and the door frame 300 when the door body 200 is opened and closed, the driving member 2 is pushed into the housing 1 to make the sealing member 4 move out of the housing 1 to fill the gap or the driving member 2 is released to make the sealing member 4 reset and retract into the housing 1, improving the sealing performance / sound insulation of the door body structure while avoiding wear caused by the long-term exposure of the sealing member 4.

[0032] As Figure 9As shown, when the pressing type sealing device 100 of the door and window is applied to the window body 400, the housing 1 is assembled on the frame of the window body 400, and the side of the housing 1 where the sealing member 4 extends is opposite to the window frame 500 (that is, the driving member 2 is opposite to the window frame 500). When the window body 400 is closed, the distance between the window body 400 and the window frame 500 is narrowed, so that the driving member 2 that moves close to the window frame 500 along with the window body 400 is pushed into the housing 1 by the window frame 500, thereby driving the sealing member 4 to extend out of the housing 1 and abut against the window frame 500, filling the gap between the window body 400 and the window frame 500, and improving the sealing and sound insulation of the window body structure; when the window body 400 is opened, the distance between the window body 400 and the window frame 500 increases to release the driving member 2, so that the sealing member 4 resets and retracts into the housing 1 and separates from the window frame 500, avoiding wear caused by long-term abutment against the window frame 500. In summary, when the pressing type sealing device 100 of the door and window is applied to the window body 400, by using the change in the distance between the window body 400 and the window frame 500 when the window body 400 is opened and closed, the driving member 2 is pushed into the housing 1 to make the sealing member 4 move out of the housing 1 to fill the gap or the driving member 2 is released to make the sealing member 4 reset and retract into the housing 1, improving the sealing / sound insulation of the door and window structure while avoiding wear caused by long-term exposure of the sealing member 4 to friction with the frame body.

[0033] In summary, the present embodiment provides a pressing type sealing device for doors and windows to solve the problem that when the existing door body (window body) is closed, there is a gap between the door body (window body) and the frame body (or bottom surface), resulting in poor sealing and sound insulation effects when the door body (window body) is closed. The main solution is to configure the pressing type sealing device for doors and windows as the housing 1, the driving member 2, the telescopic member 3 and the sealing member 4. The telescopic member 3 is rotatably connected to the driving member 2 and the sealing member 4 respectively, so that the sealing member 4 moves downward and extends out of the housing 1 when the driving member 2 moves and retracts into the housing 1, or the sealing member 4 moves upward and retracts into the housing 1 when the driving member 2 moves and extends out of the housing 1. Therefore, when the pressing type sealing device for doors and windows is applied to doors and windows, by opening and closing the doors and windows (door body or window body), the frame body (door frame or window frame) can push the driving member 2 into the housing 1, making the sealing member 4 move out of the housing 1 to fill the gap or making the frame body release the driving member 2 to make the sealing member 4 reset and retract into the housing 1, improving the sealing / sound insulation of the door and window structure while avoiding wear caused by long-term exposure of the sealing member 4 to friction with the frame body.

[0034] In the embodiment of the present utility model, the housing 1 has an assembly cavity 101, a side through port 102 and a lower through port 103. The driving member 2, the telescopic member 3 and the sealing member 4 are accommodated in the assembly cavity 101. The side through port 102 allows the driving member 2 to extend out of or retract into the housing 1 when moving back and forth, and the lower through port 103 allows the sealing member 4 to extend out of or retract into the housing 1 when moving up and down. The above settings configure the assembly cavity 101 for accommodating the driving member 2, the telescopic member 3 and the sealing member 4, the side through port 102 for the driving member 2 to extend out of or retract into the housing 1, and the lower through port 103 for the sealing member 4 to extend out of or retract into the housing 1 on the housing 1, making the overall structure of the pressing type sealing device for doors and windows compact and reasonable, and having good assembly sealing performance.

[0035] In the embodiment of the present utility model, a reset elastic member 6 is disposed through one end of the driving member 2 away from the side through port 102. The reset elastic member 6 abuts against the driving member 2 and the housing 1 respectively to move the driving member 2 in the direction of the side through port 102 and extend out of the housing 1. Specifically, the reset elastic member 6 is a spring. The above setting configures the reset elastic member 6 that moves the driving member 2 to extend out of the housing 1 at one end of the driving member 2 away from the side through port 102, so that the driving member 2 can automatically reset (move in the direction of the side through port 102 and extend out of the housing 1) after the external force is removed. The reset driving structure is simple and easy to implement.

[0036] In the embodiment of the present utility model, a buffer elastic member 5 is disposed through one end of the driving member 2 adjacent to the side through port 102. The buffer elastic member 5 is located in the assembly cavity 101 to move the driving member 2 in the direction of the side through port 102. Specifically, the buffer elastic member 5 is a spring, and the buffer elastic member 5 plays a buffering role when the driving member 2 retracts into the housing 1. The above setting configures the buffer elastic member 5 at one end of the driving member 2 adjacent to the side through port 102, so that the driving member 2 can be buffered by the buffer elastic member 5 when it moves and retracts into the housing 1.

[0037] In the embodiment of the present utility model, the driving member 2 includes a linkage rod 201, a pushing member 202, and a locking member 203. The linkage rod 201 is slidably connected to the housing 1 and can move back and forth along the housing 1. The pushing member 202 is movably connected to the linkage rod 201 and can move back and forth relative to the linkage rod 201. The locking member 203 is disposed through the pushing member 202 to lock and fix the pushing member 202 on the linkage rod 201. The pushing member 202 moves out of or retracts into the housing 1 when the linkage rod 201 moves back and forth along the linkage rod 201.

[0038] When the door and window pressing type sealing device is applied to a door body or a push-open window, the longer the length of the driving member 2 extending out of the housing 1, the larger the angle between the door body (window) and the frame when the driving member 2 contacts the frame (that is, the farther the door body is from the frame). When the driving member 2 contacts the frame at a larger angle between the door body (window) and the frame, it will cause the sealing member 4 to extend out of the housing 1 and contact the frame (or the ground) prematurely, which will increase the closing resistance of the door body (window) and make it difficult to close. The above setting makes the length of the driving member 2 extending out of the housing 1 adjustable by configuring the pushing member 202 to be movable back and forth relative to the linkage rod 201, avoiding the situation that the length of the driving member 2 extending out of the housing 1 is too long and causing the sealing member 4 to extend out of the housing 1 prematurely, and increasing the difficulty of closing the door and window.

[0039] In the embodiment of the present utility model, the linkage rod 201 has a threaded hole 204 for the pusher 202 to insert. The pusher 202 is threadedly connected to the linkage rod 201 in the threaded hole 204. The locking member 203 includes a nut threadedly connected to the linkage rod 201 and a snap ring provided on one side of the nut away from the side port 102. The above setting configures the connection method between the linkage rod 201 and the pusher 202 as a threaded connection, enabling the pusher 202 to move relative to the linkage rod 201. The connection structure is simple and the operation is convenient.

[0040] In the embodiment of the present utility model, the driving member 2 has a transverse guide hole 205 extending in the front and rear directions, and the housing 1 has a transverse guide post 104 slidably engaged with the transverse guide hole 205. More preferably, both the transverse guide hole 205 and the transverse guide post 104 are two and correspond to each other one by one, and the two transverse guide holes 205 are spaced apart in the front and rear directions. The above setting configures a transverse guide hole 205 extending in the front and rear directions on the driving member 2 and a transverse guide post 104 slidably engaged with the transverse guide hole 205 on the housing 1, enabling the driving member 2 to move back and forth along the housing 1. The connection structure is simple and the implementation is convenient.

[0041] In the embodiment of the present utility model, the seal 4 has a vertical guide hole 401 extending in the up and down directions, and the housing 1 has a vertical guide post 105 slidably engaged with the vertical guide hole 401. The above setting configures a vertical guide hole 401 extending in the up and down directions on the seal 4 and a vertical guide post 105 slidably engaged with the vertical guide hole 401 on the housing 1, enabling the seal 4 to move up and down along the housing 1. The connection structure is simple and the implementation is convenient.

[0042] In the embodiment of the present utility model, the seal 4 includes a base 402 and a sealing strip 403. The base 402 is slidably connected to the housing 1 and can move up and down along the housing 1. The sealing strip 403 is detachably and fixedly connected to one side of the base 402 opposite to the lower port 103. The above setting configures the seal 4 as a base 402 slidably connected to the housing 1 and a sealing strip 403 detachably and fixedly connected to the base 402, so that the sealing strip 403 can be replaced in time when it is damaged.

[0043] In the embodiment of the present utility model, the housing 1 has a positioning hole (not marked in the figure) opposite to the side port 102 in the front and rear directions. The positioning hole is for the end of the driving member 2 away from the side port 102 to insert. The above setting configures a positioning hole on the housing 1 for the end of the driving member 2 away from the side port 102 to insert, enabling the driving member 2 to be stably assembled with the housing 1.

[0044] In the embodiment of the present utility model, the housing 1 is in a shape of "J". Since the housing 1 is in a shape of "J", it is convenient for the positioning and assembly of the door and window push-press sealing device when it is installed in the door body.

[0045] Embodiment 2: As Figures 7-9As shown, the difference from Embodiment 1 is that the housing 1 has a U-shaped portion 106 and an external connection portion 107 provided above the U-shaped portion 106. A connection hole 108 is formed on the external connection portion 107, and the driving member and the sealing member are slidably connected to the U-shaped portion 106. Since the housing 1 has a U-shaped portion 106 and an external connection portion 107, and the external connection portion 107 has a connection hole 108, it is convenient to assemble the window and door press-type sealing device on the window frame.
