Description
Technical Field
[0001] This utility model relates to the field of air conditioning exhaust duct technology, specifically a window frame structure for installing air conditioning exhaust ducts. Background Technology
[0002] An air conditioner is a device that can regulate and control parameters such as temperature, humidity, cleanliness, and airflow of ambient air. It is a common household appliance. Air conditioners can be divided into several types according to different installation and usage methods, such as floor-standing air conditioners, wall-mounted air conditioners, and portable air conditioners. Among them, portable air conditioners are more flexible than traditional floor-standing and wall-mounted air conditioners because they are convenient for users to move around.
[0003] However, existing portable air conditioners typically require exhaust ducts to expel hot air outdoors through windows during installation. This necessitates the use of specialized window frame assemblies to install the exhaust ducts on the windows, and a certain degree of airtightness must be maintained during the exhaust process to prevent hot air backflow and outdoor air from entering the room. However, existing window frame structures are not sturdy after installation, easily loosening and falling off, which can lead to leaks, seepage, or exhaust duct detachment and other air leakage problems.
[0004] In addition, existing window frame components have poor versatility and are relatively complicated to install on windows, causing inconvenience to users.
[0005] To address the above shortcomings, we need to develop a window frame structure for installing air conditioning exhaust ducts to meet the needs of a wide range of users. Utility Model Content

The groove opening is located between the third guide rail segment c and the fourth guide rail segment d.
[0012] As described above, in a window frame structure for installing an air conditioning exhaust pipe, the sliding bracket structure extends a first bracket segment g from a position close to the sliding guide rail structure. The first bracket segment g extends a second bracket segment h and a third bracket segment i laterally in the direction of extension. The second bracket segment h and the third bracket segment i are connected to the inner groove of the guide rail of the sliding guide rail structure, and the first bracket segment g is connected to the groove opening of the sliding guide rail structure.
[0013] As described above, a window frame structure for installing an air conditioning exhaust pipe includes a limiting and sealing structure comprising a pad structure for reducing sliding friction and ensuring airtightness, wherein the pad structure is located between the sliding bracket structure and the inner groove of the guide rail.
[0014] As described above, a window frame structure for installing an air conditioning exhaust pipe includes a padding structure comprising a first guide rail padding and a second guide rail padding.

The first bracket structure is slidably connected to the first guide rail structure, and the second bracket structure is slidably connected to the second guide rail structure. The positioning groove structure of the window frame sliding member is located between the first bracket structure and the second bracket structure, and the positioning mating hole of the window frame body is located between the first guide rail structure and the second guide rail structure.
[0017] The beneficial effects of this utility model are as follows:
[0018] 1. This utility model uses a window frame main body and a window frame sliding component to form a window frame assembly installed on a window. The window frame main body is equipped with the window frame sliding component through a sliding guide rail structure, allowing the window frame sliding component to slide directionally along the sliding guide rail structure, thereby adjusting the extension and retraction length of the window frame structure to adapt to different window sizes and achieve good versatility, improving the adaptability and practicality of the window frame structure.

[0024] Figure 6 for Figure 5 BB section view. Detailed Implementation
[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0026] Example 1:
[0027] like Figures 1 to 6 The window frame structure shown includes a window frame body 1 and a window frame slider 2. The window frame body 1 is used to install on a window on a building wall and can be fixed in place on the window after installation. The window frame slider 2 is a sliding adjustment component installed on the window frame body 1 to adjust the extension length. By sliding the window frame slider 2 on the window frame body 1 to adjust the extension distance, it can adapt to window types of different widths and sizes, achieving good adaptability and versatility.
[0028] More specifically, the window frame body 1 includes a mounting hole structure 11 for installing an exhaust pipe and a sliding guide rail structure 12 for installing the window frame sliding member 2. The mounting hole structure 11 is used for detachably connecting the exhaust pipe structure of an air conditioner. After the exhaust pipe is installed in the mounting hole structure 11, the air conditioner can exhaust excess air from the mounting hole structure 11 via the exhaust pipe. The window frame sliding member 2 is mounted on the sliding guide rail structure 12 and can slide directionally back and forth along the length of the sliding guide rail structure 12. The window frame sliding member 2 includes a sliding bracket structure 21 for cooperating with and connecting the sliding guide rail structure 12. The sliding bracket structure 21 can slide directionally on the sliding guide rail structure 12. In use, the window frame sliding member 2 extends the sliding bracket structure 21 into the sliding guide rail structure 12. The sliding rail structure 12 is used in conjunction with the sliding connection. The main body of the window frame 1 is then installed on one of the left and right sides of the window. The sliding window frame sliding member 2 extends out and rests against the other left and right sides of the window, thus adapting to the width of the window. The window frame structure is easy to assemble and disassemble and is easy to operate. On this basis, both the sliding guide rail structure 12 and the sliding bracket structure 21 have a limiting sealing structure 3 for sealing the sliding position. When sliding, the limiting sealing structure 3 seals the sliding gap between the sliding guide rail structure 12 and the sliding bracket structure 21, so that the window frame structure has better sealing performance. By filling the installation gap and sliding gap through the limiting sealing structure 3, the stability of sliding can be guaranteed, the window frame sliding member 2 can be prevented from loosening and falling off, the airtight connection between the inside and outside of the window can be reduced, and the occurrence of air leakage or seepage can be reduced.
[0029] As another embodiment 101 of embodiment 1, the limiting sealing structure 3 can be integrally formed on the sliding guide rail structure 12 and / or the sliding bracket structure 21.
[0030] As another embodiment 101 of embodiment 1, the limiting sealing structure 3 is installed on the sliding guide structure 12 and / or the sliding bracket structure 21 in a detachable connection (such as pasting, fastening, etc.).
[0031] Example 2:
[0032] like Figure 6 As shown, either the sliding guide rail structure 12 or the sliding bracket structure 21 has a limiting sealing structure 3 for sealing the sliding position. In this embodiment, the limiting sealing structure 3 is disposed on the sliding guide rail structure 12. When sliding, the limiting sealing structure 3 seals the sliding gap between the sliding guide rail structure 12 and the sliding bracket structure 21, so that the window frame structure has better sealing performance.
[0033] More specifically, the limiting sealing structure 3 of this embodiment includes a pad structure for reducing sliding friction and ensuring airtightness. The pad structure is located between the sliding bracket structure 21 and the inner slide groove 121 of the guide rail. The pad structure includes a first guide rail pad 31 and a second guide rail pad 32. The first guide rail pad 31 is located on the sliding guide rail structure 12 to limit the sliding position of the sliding bracket structure 21 in the first direction n. The second guide rail pad 32 is located on the sliding guide rail structure 12 to limit the sliding position of the sliding bracket structure 21 in the second direction s.
[0034] Example 3:
[0035] like Figure 6 As shown, either the sliding guide rail structure 12 or the sliding bracket structure 21 has a limiting sealing structure 3 for sealing the sliding position. In this embodiment, the limiting sealing structure 3 is disposed on the sliding bracket structure 21. When sliding, the limiting sealing structure 3 seals the sliding gap between the sliding guide rail structure 12 and the sliding bracket structure 21, so that the window frame structure has better sealing performance.
[0036] More specifically, the limiting sealing structure 3 of this embodiment includes a pad structure for reducing sliding friction and ensuring airtightness. The pad structure is located between the sliding bracket structure 21 and the inner slide groove 121 of the guide rail. The pad structure includes a first bracket pad 33 and a second bracket pad 34. The first bracket pad 33 is located on the sliding bracket structure 21 to limit the sliding position of the sliding bracket structure 21 in the third direction w. The second bracket pad 34 is located on the sliding bracket structure 21 to limit the sliding position of the sliding bracket structure 21 in the fourth direction e.
[0037] Example 4:
[0038] To solve the positioning problem of the window frame sliding component 2 on the window frame body 1 during the sliding process, such as Figure 6 The window frame structure shown includes a positioning fastener 4 for restricting the sliding position of the window frame sliding member 2. The positioning fastener 4 is installed in the positioning mating hole 13 of the window frame body 1. The positioning fastener 4 can move directionally along the central axis of the positioning mating hole 13. When the positioning fastener 4 moves toward the window frame sliding member 2 and presses against the surface of the window frame sliding member 2, the friction generated by the pressing against the surface of the window frame sliding member 2 restricts the movement position of the window frame sliding member 2, realizing the positioning of the window frame sliding member 2 after sliding extension adjustment. When the positioning fastener 4 moves away from the window frame sliding member 2, the positioning fastener 4 disengages from the surface of the window frame sliding member 2, and the window frame sliding member 2 resumes its smooth reciprocating sliding function, realizing the effect of sliding adjustment or disassembly.
[0039] As another embodiment 401 of embodiment 4, such as Figure 6 The diagram illustrates a window frame structure for installing an air conditioning exhaust duct. The positioning fastener 4 is a wing bolt with a wing-shaped handle 41 for easy tightening. The positioning fastener 4 is threaded into the positioning mating hole 13 and moves axially. The window frame sliding member 2 includes a positioning groove structure 22 for engaging the positioning fastener 4. The positioning fastener 4 can press against the positioning groove structure 22 to limit the sliding position of the window frame sliding member 2. The wing-shaped handle 41 of the wing bolt is integrally formed at the tightening position of the wing bolt, facilitating user grip and tightening. Without the need for additional tightening tools (such as screwdrivers or wrenches), the wing bolt can be axially moved in the positioning mating hole 13 by directly tightening it with the wing handle 41. When the wing bolt is tightened in the forward direction, it moves against the positioning slide groove structure 22, and the self-locking of the thread and the spiral top pressure can achieve stable top pressure friction to limit the sliding position of the window frame sliding member 2. When the wing bolt is tightened in the reverse direction, it can easily disengage from the surface of the positioning slide groove structure 22, achieve contact with the window frame sliding member 2 to limit it and restore the sliding function. It is convenient to operate and easy for users to use.
[0040] As another embodiment 402 of embodiment 4, the positioning fastener 4 can also be an elastic deformable part (including springs or spring sheets, etc.) that elastically presses against the surface of the positioning slide groove structure 22, and uses elastic pressing contact to achieve stable pressing friction, so as to limit the sliding position of the window frame sliding part 2.
[0041] Example 5:
[0042] like Figure 3 and Figure 4 The window frame structure shown is used for installing air conditioning exhaust pipes. The sliding guide rail structure 12 includes an inner guide rail groove 121 for limiting the sliding direction of the sliding bracket structure 21. The inner guide rail groove 121 has a groove opening 122 for limiting the installation gap of the sliding bracket structure 21.
[0043] More specifically, the inner slide groove 121 of the guide rail protrudes from the inner side u of the window frame body 1 toward the outside and extends vertically to form a first guide rail segment a. The first guide rail segment a extends toward the middle of the inner side u to form a second guide rail segment b. The second guide rail segment b is parallel to the inner side u. The second guide rail segment b extends toward the inner side u to form a third guide rail segment c. The inner slide groove 121 of the guide rail extends from the inner side u of the window frame body 1 toward the third guide rail segment c to form a fourth guide rail segment d. The first guide rail segment a, the second guide rail segment b, the third guide rail segment c, and the fourth guide rail segment d enclose the inner slide groove 121 to form a sliding space for the sliding bracket structure 21 to move. The groove opening 122 is located between the third guide rail segment c and the fourth guide rail segment d. The sliding bracket structure 21 extends into the sliding space and moves back and forth in a directional manner along the guide rail direction of the sliding space. Under smooth and stable sliding conditions, it can ensure good airtightness and is not prone to air leakage, making it convenient for users.
[0044] As another embodiment 501 of embodiment 5, the limiting sealing structure 3 includes a pad structure for reducing sliding friction and ensuring airtightness. The pad structure is located in the inner groove 121 of the guide rail. The pad structure includes a first guide rail pad 31 and a second guide rail pad 32. The first guide rail pad 31 is located at the end of the third guide rail segment c near the groove opening 122 to limit the installation position of the sliding support structure 21 in the first direction n of the inner groove 121 of the guide rail. The second guide rail pad 32 is located at the end of the fourth guide rail segment d near the groove opening 122 to limit the installation position of the sliding support structure 21 in the second direction s of the inner groove 121 of the guide rail. The sliding support structure 21 is restricted within the range of the groove opening 122 from opposite directions, thereby enhancing the stability of sliding and the airtightness of the connection.
[0045] Example 6:
[0046] like Figure 3 and Figure 4 The diagram illustrates a window frame structure for installing an air conditioning exhaust duct. The sliding bracket structure 21 extends a first bracket segment g from a position near the sliding guide rail structure 12. The first bracket segment g extends laterally in the direction of extension into a second bracket segment h and a third bracket segment i. The second bracket segment h and the third bracket segment i are connected to the inner sliding groove 121 of the sliding guide rail structure 12. The first bracket segment g is connected to the opening 122 of the sliding groove in the sliding guide rail structure 12. The second bracket segment h and the third bracket segment i extend into the sliding space and move back and forth directionally along the guide rail direction of the sliding space. Under smooth and stable sliding conditions, good airtightness is ensured, preventing air leakage and facilitating user operation.
[0047] As another embodiment 601 of embodiment 6, the limiting sealing structure 3 includes a pad structure for reducing sliding friction and ensuring airtightness. The pad structure is located in the sliding bracket structure 21. The pad structure includes a first bracket pad 33 and a second bracket pad 34. The first bracket pad 33 is located on the side of the sliding bracket structure 21 near the first guide rail section a to limit the installation position of the sliding bracket structure 21 in the third direction w of the guide rail groove 121. The second bracket pad 34 is located on the side of the sliding bracket structure 21 near the third guide rail section c to limit the installation position of the sliding bracket structure 21 in the fourth direction w of the guide rail groove 121. The sliding bracket structure 21 is restricted within the range of the groove opening 122 from opposite directions to enhance the stability of sliding and the airtightness of the connection.
[0048] Example 7:
[0049] Based on Example 1, such as Figures 1 to 6 The diagram illustrates a window frame structure for installing an air conditioning exhaust duct. The sliding guide rail structure 12 includes a first guide rail structure 101 and a second guide rail structure 102 arranged along the sliding direction. The sliding bracket structure 21 includes a first bracket structure 201 and a second bracket structure 202 arranged along the sliding direction. The first bracket structure 201 is slidably connected to the first guide rail structure 101, and the second bracket structure 202 is slidably connected to the second guide rail structure 102. The positioning groove structure 22 of the window frame sliding member 2 is located between the first bracket structure 201 and the second bracket structure 202. The positioning mating hole 13 of the window frame body 1 is located between the first guide rail structure 101 and the second guide rail structure 102. The double guide rail structure design can enhance the balanced force of the window frame sliding member 2 during movement, improve the sliding stability of the window frame sliding member 2 during movement, and facilitate user use.
