[0032] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the drawings are exemplary.

[0033] Below, reference is made to Figures 1 - 10 to describe a limiting device for a window according to an embodiment of the present invention.

[0034] As Figures 1 - 10 shown, the limiting device 100 for a window according to the present invention includes: a substrate 10 and a limiting member 20. The substrate 10 is used for being mounted on the first window 200. One end of the limiting member 20 is disposed on the substrate 10, and the other end of the limiting member 20 is away from the substrate 10. The other end of the limiting member 20 is a limiting end 21. The limiting end 21 is used for limiting cooperation with the second window 300. The second window 300 is movable relative to the first window 200. The limiting device 100 for a window further includes: a stopper 30. The stopper 30 is used for being mounted on the second window 300 to perform a stop cooperation with the limiting end 21. Among them, the stopper 30 and the substrate 10 are integrally formed, and the stopper 30 is adapted to be separated from the substrate 10 under an external force.

[0035] It can be understood that the substrate 10 and the limiting member 20 constitute the main structure of the limiting device. The substrate 10 provides an installation position for the limiting member 20, facilitating the installation of the limiting member 20 on the substrate 10. The substrate 10 is disposed in the first window 200, enabling the substrate 10 to be fixed relative to the first window 200. One end of the limiting member 20 is connected to the substrate 10, enabling the limiting member 20 and the substrate 10 to form an integral body, and further facilitating the fixation of both the limiting member 20 and the substrate 10 in the first window 200. The other end of the limiting member 20 is away from the substrate 10, enabling the limiting member 20 to move away from or close to the substrate 10.

[0036] A limiting end 21 is formed at the end of the limiting member 20 away from the substrate 10. The limiting end 21 selectively abuts against the second window 300. This arrangement enables the second window 300 to selectively move relative to the first window 200. When the limiting end 21 moves away from the substrate 10, the limiting end 21 and the second window 300 are in abutting cooperation, enabling the second window 300 to be stationary relative to the first window 200. When the limiting end 21 moves close to the substrate 10, the abutting between the limiting end 21 and the second window 300 is released, enabling the second window 300 to move relative to the first window 200, and further facilitating the opening and closing of the second window 300 relative to the first window 200.

[0037] In addition, the stop member 30 is also one of the main structures of the limiting device. The stop member 30 is installed on the second window 300, enabling the stop member 30 and the second window 300 to be connected as an integral body. The stop member 30 and the limiting end 21 are in stop cooperation. This arrangement enables the first window 200 and the second window 300 to be in stop cooperation through the stop member 30 and the limiting end 21. When the first window 200 and the second window 300 are relatively stationary, the stop member 30 and the limiting end 21 are in stop cooperation. When the second window 300 moves relative to the first window 200, the stop cooperation between the stop member 30 and the limiting end 21 is released, and further facilitating the opening and closing of the second window 300 relative to the first window 200.

[0038] Among them, the stop member 30 and the substrate 10 are integrally formed. This facilitates the manufacture of the limiting device and can also save the space occupied by the transportation of the limiting device, thus facilitating the storage and turnover of the limiting device. The stop member 30 can be separated from the substrate 10 under the action of an external force, facilitating the setting of the substrate 10 in the first window 200 and the stop member 30 in the second window 300. The stop member 30 and the substrate 10 are in stop cooperation, facilitating the opening and closing of the second window 300 relative to the first window 200.

[0039] Thus, by disposing the substrate 10 on the first window 200, disposing the limiting member 20 on the substrate 10, and one end of the limiting member 20 can be away from the substrate 10, so that the limiting member 20 can selectively approach or move away from the first window 200. A limiting end 21 is provided at the end of the limiting member 20 that is not connected to the substrate 10, and the limiting end 21 is in limiting cooperation with the second window 300, so that the second window 300 can selectively move relative to the first window 200. A stop member 30 is provided on the second window 300, and the stop member 30 is in stop cooperation with the limiting end 21, which facilitates the selective movement of the second window 300 relative to the first window 200. Moreover, the stop member 30 and the substrate 10 are integrally formed, which facilitates manufacturing and storage. The stop member 30 and the substrate 10 can be separated by an external force, which facilitates the installation of the substrate 10 on the first window 200 and the installation of the stop member 30 on the second window 300, and further facilitates the relative movement between the first window 200 and the second window 300.

[0040] Among them, as Figure 6 、 Figure 8 and Figure 9 shown, a through hole 11 is formed in the middle of the substrate 10, one end of the limiting member 20 is connected to one end of the through hole 11, and the limiting member 20 is composed of at least a part of the material of the substrate 10 at the position of the through hole 11.

[0041] It can be understood that a through hole 11 is formed in the middle of the substrate 10, so that the through hole 11 can provide a moving space for the limiting member 20, which further facilitates the selective approach or movement away of the limiting member 20 from the substrate 10. One end of the limiting member 20 is connected to one end of the through hole 11, that is, the limiting member 20 is connected to the substrate 10, so that the limiting member 20 and the through hole 11 can be connected into a whole, which further facilitates the movement of the limiting member 20 relative to the substrate 10.

[0042] Particularly, as Figures 6 - 10 shown, the limiting member 20 is configured as an elastic member bent into a curved shape. Such a setting can make the limiting member 20 have elasticity. When an external force presses the limiting member 20, the limiting end 21 approaches the substrate 10, so that the limiting cooperation between the limiting end 21 and the stop member 30 can be released, so that the second window 300 can move relative to the first window 200, and further the opening requirement of the second window 300 can be met. When there is no external force pressing the limiting member 20, the fiber is short and moves away from the substrate 10, so that the limiting end 21 and the stop member 30 are in limiting cooperation, so that the second window 300 and the first window 200 are relatively stationary.

[0043] Among them, the curved structure can enhance the elasticity of the limiting member 20, so that the limiting member 20 can have a restoring force, which can not only meet the convenience of the opening and closing of the second window 300 relative to the first window 200, but also improve the limiting cooperation degree between the first window 200 and the second window 300. Moreover, the elastic member is easy to manufacture, which can save the cost of the limiting device and facilitate the transportation of the limiting device.

[0044] In addition, as Figure 6 and Figure 9 shown, the limiting member 20 includes: a connecting portion 22, an extending portion 23 and a limiting portion 24. One end of the connecting portion 22 is connected to the substrate 10, the connecting portion 22 is configured as an arc, the extending portion 23 is connected to the other end of the connecting portion 22, the extending portion 23 is configured as an arc or a straight line, the limiting portion 24 is connected to the extending portion 23, the limiting end 21 is arranged on the limiting portion 24, and the limiting portion 24 is configured as an arc or a straight line.

[0045] It can be understood that the connecting extending portion 23 and the limiting portion 24 constitute the main structure of the limiting member 20. One end of the connecting portion 22 is connected to one end of the through hole 11, and the connecting portion 22 is composed of at least a part of the material of the substrate 10 at the position of the through hole 11, so that the limiting member 20 can be connected to the substrate 10. The extending portion 23 is connected to the end of the connecting portion 22 far from the substrate 10, so that the extending portion 23, the connecting portion 22 and the substrate 10 can be connected in sequence. The limiting portion 24 is connected to the end of the extending portion 23 far from the connecting portion 22, so that the limiting portion 24, the extending portion 23, the connecting portion 22 and the substrate 10 can be connected in sequence. Moreover, the limiting portion 24 is provided with the limiting end 21, so that the connecting portion 22, the extending portion 23 and the limiting portion 24 can have elasticity, and the limiting end 21 can be controlled to move away from or close to the substrate 10 through the elastic restoring force, thereby facilitating the selective limiting cooperation between the limiting end 21 and the stopper 30.

[0046] Among them, the connecting portion 22 is configured as an arc, and the extending portion 23 is configured as an arc or a straight line. Such a setting can make the extending portion 23 inclined relative to the horizontal plane of the substrate 10, so that one end of the limiting member 20 can move away from the substrate 10, and thus there can be a rebounding space between the limiting member 20 and the substrate 10. The limiting portion 24 is configured as an arc or a straight line. Such a setting can make the limiting end 21 move away from the substrate 10, and the limiting end 21 is close to the stopper 30, so as to facilitate the stopping cooperation between the limiting end 21 and the stopper 30, and further facilitate the static or movement between the first window 200 and the second window 300.

[0047] In addition, as Figure 9 and Figure 10As shown, the limiting device 100 for a window further includes: a weakening connecting member 40, which is connected between the substrate 10 and the stopper 30, and the weakening connecting member 40 is integrally formed with the substrate 10 and the stopper 30 respectively.

[0048] It can be understood that one end of the weakening connecting member 40 is connected to the substrate 10, and the other end is connected to the stopper 30. Such a setting can enable the weakening connecting member 40 to connect the substrate 10 and the stopper 30, so that the stopper 30 and the substrate 10 can be connected into a whole, which is convenient for the integral molding of the substrate 10 and the stopper 30, convenient for the manufacturing of the stopper 30 and the substrate 10, and can also save the space occupied by the transportation of the stopper 30 and the substrate 10, thus facilitating the storage and turnover of the stopper 30 and the substrate 10.

[0049] Moreover, the weakening connecting member 40 is easy to disassemble with the assistance of an external force, so that the stopper 30 can be separated from the substrate 10 under the action of an external force, thus facilitating the setting of the substrate 10 on the first window 200 and the stopper 30 on the second window 300, and the stopper 30 and the substrate 10 are in a stopper cooperation, so as to facilitate the opening and closing of the second window 300 relative to the first window 200.

[0050] In particular, as Figure 9 and Figure 10 shown, the thickness of the weakening connecting member 40 is less than the thickness of the substrate 10; the thickness of the weakening connecting member 40 is less than the thickness of the stopper 30.

[0051] It can be understood that the thickness of the weakening connecting member 40 is smaller than the thickness of the substrate 10. This can not only distinguish the boundary between the stopper 30 and the substrate 10, but also ensure that the weakening connecting member 40 disconnects from the substrate 10 after being subjected to an external force, so as to ensure the convenience of manufacturing and transportation of the limiting device, and also facilitate the setting of the substrate 10 on the first window 200 after the weakening connecting member 40 is separated from the substrate 10.

[0052] Similarly, the thickness of the weakening connecting member 40 is smaller than the thickness of the stopper 30. This can not only distinguish the boundary between the stopper 30 and the substrate 10, but also ensure that the weakening connecting member 40 disconnects from the stopper 30 after being subjected to an external force, so as to ensure the convenience of manufacturing and transportation of the limiting device, and also facilitate the setting of the stopper 30 on the second window 300 after the weakening connecting member 40 is separated from the stopper 30.

[0053] Such a setting enables the integrally formed stopper 30, weakened connecting member 40, and substrate 10, which facilitates the manufacture of the limiting device and can also save the space occupied by the transportation of the limiting device, thereby facilitating the storage and turnover of the limiting device. Under the action of an external force, the stopper 30 can be separated from the substrate 10, thereby facilitating the arrangement of the substrate 10 in the first window 200 and the stopper 30 in the second window 300. The stopper 30 and the substrate 10 are in a stop fit, thereby facilitating the opening and closing of the second window 300 relative to the first window 200.

[0054] Among them, as Figure 9 and Figure 10 shown, the weakened connecting member 40 includes: a plurality of connecting arms 41, the connecting arms 41 being connected between the substrate 10 and the stopper 30, and the plurality of connecting arms 41 being spaced apart in the length direction of the stopper 30.

[0055] It can be understood that the plurality of connecting arms 41 are arranged at intervals along the width direction of the substrate 10 and at intervals in the length direction of the stopper 30. Such a setting can make the connecting arms 41 located between the substrate 10 and the stopper 30, which can not only distinguish the boundaries between the stopper 30 and the substrate 10, but also, after being subjected to an external force, cause the weakened connecting member 40 to disconnect from the stopper 30, thereby ensuring the convenience of the manufacture and transportation of the limiting device, and also facilitating the arrangement of the substrate 10 in the first window 200 and the stopper 30 in the second window 300 after the weakened connecting member 40 is separated from the stopper 30.

[0056] Moreover, the stopper 30, the plurality of connecting arms 41, and the substrate 10 are integrally formed, which facilitates the manufacture of the limiting device and can also save the space occupied by the transportation of the limiting device, thereby facilitating the storage and turnover of the limiting device. Under the action of an external force, the stopper 30 can be separated from the substrate 10, thereby facilitating the arrangement of the substrate 10 in the first window 200 and the stopper 30 in the second window 300. The stopper 30 and the substrate 10 are in a stop fit, thereby facilitating the opening and closing of the second window 300 relative to the first window 200.

[0057] In addition, as Figure 6 、 Figure 8 and Figure 9 shown, a first bonding portion 12 is provided on the back surface of the substrate 10, and the first bonding portion 12 is used for bonding with the first window 200; a second bonding portion 31 is provided on the back surface of the stopper 30, and the second bonding portion 31 is used for bonding with the second window 300; the stopper 30 is provided with a mounting hole 32 for a fastener to pass through, and the mounting hole 32 is a circular hole or a long strip hole.

[0058] It can be understood that the limiting end 21 is located on one side of the substrate 10, and the first bonding portion 12 is located on the side of the substrate 10 away from the limiting end 21, that is, the first bonding portion 12 is located on the back surface of the substrate 10. Such a setting can make the first bonding portion 12 located between the substrate 10 and the first window 200, so that the substrate 10 can be bonded to the first window 200, and the substrate 10 and the first window 200 can be made more firm.

[0059] When the stopper 30, the weakening connecting member 40 and the substrate 10 are integrally formed, the first bonding portion 12 and the second bonding portion 31 are respectively arranged on the same side of the substrate 10 and the stopper 30. Such a setting can make the second bonding portion 31 located between the stopper 30 and the second window 300, so that the stopper 30 can be bonded to the second window 300, and the stopper 30 and the second window 300 can be made more firm.

[0060] A plurality of mounting holes 32 are arranged on the stopper 30, and the plurality of mounting holes 32 are arranged at intervals along the length direction of the stopper 30. Such a setting facilitates the fastener to pass through the mounting hole 32 and the second window 300, so that the stopper 30 can be fixed to the second window 300. Moreover, the mounting hole 32 is a circular hole or a long strip hole, so that the edge of the circular hole or the long strip hole can be in a stop fit with the edge of the fastener, so that the mounting hole 32 can limit the fastener, and the fastener can be more firmly connected to the stopper 30 and the second window 300.

[0061] In addition, as Figure 6 and Figure 9 shown, an annular convex edge 33 protruding toward one side in the thickness direction is arranged on the edge of the stopper 30. Such a setting can make the annular convex edge 33 away from the second window 300, so that the annular convex edge 33 can protect the fastener, and can also prevent the fastener from accidentally touching the user, and further can ensure the firmness between the stopper 30 and the second window 300, and can also improve the safety of the limiting device.

[0062] The limiting device 100 for a window according to the present invention includes: a substrate 10 and a limiting member 20. The substrate 10 is used for being installed on the first window 200. One end of the limiting member 20 is arranged on the substrate 10, and the other end of the limiting member 20 is away from the substrate 10. The other end of the limiting member 20 is a limiting end 21, and the limiting end 21 is used for being in a limiting fit with the second window 300. The second window 300 is movable relative to the first window 200. The limiting device 100 for a window further includes: a stopper 30, and the stopper 30 is used for being installed on the second window 300 to be in a stop fit with the limiting end 21.

[0063] By disposing the substrate 10 on the first window 200, disposing the limiting member 20 on the substrate 10, and one end of the limiting member 20 can be away from the substrate 10, so that the limiting member 20 can selectively approach or move away from the first window 200. A limiting end 21 is provided at the end of the limiting member 20 that is not connected to the substrate 10, and the limiting end 21 is in limiting cooperation with the second window 300, so that the second window 300 can selectively move relative to the first window 200. A stop member 30 is provided on the second window 300, and the stop member 30 is in stop cooperation with the limiting end 21, so as to facilitate the selective movement of the second window 300 relative to the first window 200. Moreover, the stop member 30 and the substrate 10 are integrally formed, which is convenient for manufacturing and storage. The stop member 30 and the substrate 10 can be separated by an external force, so as to facilitate the installation of the substrate 10 on the first window 200 and the installation of the stop member 30 on the second window 300, and further facilitate the relative movement between the first window 200 and the second window 300.
