[0017] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] The existing window frames of portable air conditioners are mainly installed and fixed using separate bolts and nuts. This fixing method has the following drawbacks: the bolts, nuts and other connecting parts are small in size and are very easy to fall apart and lose during disassembly and assembly. Moreover, it is necessary to use tools to tighten or loosen multiple bolts one by one, which is cumbersome, time-consuming and laborious. Once the bolts are tightened, the position of the window frame is fixed, which cannot adapt to window frames with different installation requirements, resulting in poor versatility. This utility model creatively provides a window frame assembly for a portable air conditioner; a first window frame is fixedly mounted on a window frame, and a second window frame is movably mounted on the first window frame; the locking mechanism includes an abutment, an elastic member, and a top member, the abutment being disposed near the second window frame, and the elastic member being disposed near the first window frame; in the direction of movement of the top member, one end of the top member is connected to the abutment, and the other end extends away from the abutment. The locking mechanism is configured such that: when the end of the top member away from the abutment member is not under force, the abutment member abuts against the second window frame under the action of the elastic member, thereby locking the second window frame to the first window frame; when the end of the top member away from the abutment member is under force and the top member drives the abutment member to disengage from the second window frame, the second window frame can move relative to the first window frame. The locking mechanism enables quick, tool-free locking and unlocking, effectively preventing parts loss and improving operational convenience. It also provides convenient position adjustment capabilities and enhances versatility.

[0022] like Figures 1 to 8b As shown, this embodiment provides a window frame assembly for a portable air conditioner; the portable air conditioner includes an exhaust duct, which is installed at the window via the window frame assembly, and the exhaust duct connects the interior and exterior of the portable air conditioner for exhausting air from the portable air conditioner to the exterior; the window frame assembly includes: First window frame 1 and second window frame 2, the first window frame 1 is fixedly installed on the window frame, and the second window frame 2 is movably installed on the first window frame 1; The locking mechanism 3 includes an abutment 31, an elastic element 32, and a top element 33. Both the abutment 31 and the elastic element 32 are disposed between the first window frame 1 and the second window frame 2, with the abutment 31 positioned closer to the second window frame 2 and the elastic element 32 positioned closer to the first window frame 1. Specifically, from the first window frame 1 to the second window frame 2, the elastic element 32 and the abutment 31 are sequentially arranged. The elastic element 32 applies an elastic force to the abutment 31, causing the abutment 31 to abut against the second window frame 2. The top element 33 can be controlled to move, and the direction of movement of the top element 33 is parallel to the direction of the elastic force of the elastic element 32. In the direction of movement of the top element 33, one end of the top element 33 is fixedly connected to the abutment 31 without relative movement (specifically, a fixed connection), and the other end extends away from the abutment 31. The locking mechanism 3 has a locked state in which the second window frame 2 is locked to the first window frame 1, and an unlocked state in which the second window frame 2 can move relative to the first window frame 1; the locking mechanism 3 is configured as follows: When the top member 33 is not subjected to force at the end away from the abutting member 31 in the direction of the elastic force of the elastic member 32, the abutting member 31 abuts against the second window frame 2 under the action of the elastic member 32, the locking mechanism 3 is in the locked state, and the second window frame 2 cannot move relative to the first window frame 1. In the direction of the elastic force of the elastic member 32, when the end of the top member 33 away from the abutment member 31 is subjected to force and the top member 33 drives the abutment member 31 to disengage from the second window frame 2, the locking mechanism 3 is in the loose state, and the second window frame 2 can move relative to the first window frame 1; the position of the second window frame 2 relative to the first window frame 1 can be adjusted according to actual installation requirements; specifically, in the direction of the elastic force of the elastic member 32, when the end of the top member 33 away from the abutment member 31 is subjected to force and the force is greater than or equal to the elastic force of the elastic member 32, the top member 33 drives the abutment member 31 to not abut or move away from the second window frame 2, and the locking mechanism 3 is in the loose state.

[0023] Thus, through the coordinated action of the elastic element 32, the abutment element 31, and the top element 33, the user only needs to perform a simple operation on the top element 33 to switch the locking mechanism 3 between the locked and unlocked states, thereby locking or unlocking the second window frame 2, which greatly simplifies the installation and disassembly process of the window frame and improves the efficiency of installation and disassembly; the locking mechanism 3 is set on the window frame as an integral mechanism and is not easy to lose.

[0024] The following further explains the configuration of the top member 33: the first window frame 1 has a through hole 111; the top member 33 is movably inserted into the through hole 111, and an operating member 34 is provided at the end of the top member 33 away from the abutment member 31; by operating the operating member 34 in a direction away from the second window frame 2, the top member 33 can be moved away from the second window frame 2, and the locking mechanism 3 can be switched from the locked state to the released state; without the need for manual assembly of the first window frame 1 and the second window frame 2, the second window frame 2 can be locked when the operating member 34 is not operated; when the operating member 34 is operated, the second window frame 2 can be released, realizing quick locking and unlocking of the second window frame 2 and adjustment of the position of the second window frame 2 relative to the first window frame 1. Furthermore, the top member 33 has a through hole 331 at the end away from the abutting member 31; the operating member 34 is a pull ring, a hook, or a pin, which is inserted into the through hole 331; by pulling the pull ring, hook, or pin away from the abutting member 31, the top member 33 can cause the abutting member 31 to not abut against or move away from the second window frame 2. Preferably, the operating element 34 is a pull ring; it is aesthetically pleasing and easy and labor-saving to operate.

[0025] Thus, the combination of elastic element 32, abutment element 31 and operating element 34 enables the second window frame 2 to be quickly locked. Users do not need to assemble it themselves; they only need to operate the operating element 34 to complete the locking operation. This not only simplifies the process of locking and unlocking the second window frame 2 and adjusting the position of the second window frame 2 relative to the first window frame 1, improving the efficiency of disassembly and assembly, but also avoids assembly problems caused by improper operation by users, significantly improving the reliability of the product and the user experience.

[0026] The following describes the contact force between the abutting member 31 and the second window frame 2. The abutting member 31 is provided with an anti-slip structure 311 on the side near the second window frame 2. The anti-slip structure 311 abuts against the second window frame 2, so that the second window frame 2 is locked to the first window frame 1. Specifically, the anti-slip structure 311 is an anti-slip rib, and there are multiple anti-slip ribs. The multiple anti-slip ribs are arranged sequentially on the abutting member 31. The extension direction of the anti-slip ribs intersects with or is spatially staggered with the movement direction of the second window frame 2 relative to the first window frame 1, so that when the locking mechanism 3 is in the locked state, the second window frame 2 can be firmly locked to the first window frame 1.

[0027] It should be noted that the anti-slip structure 311 is not necessary. The abutment part 31 can be designed without the anti-slip structure 311 according to actual needs.

[0028] The connection method between the first window frame 1 and the second window frame 2 is described below. The second window frame 2 is slidably mounted on the first window frame 1. By adjusting the position of the second window frame 2 relative to the first window frame 1, the window frame assembly can be adapted to window frames with different installation requirements. Wherein, the sliding direction of the second window frame 2 is parallel to the length direction of the second window frame 2, and the extension direction of the anti-slip rib is perpendicular to the sliding direction of the second window frame 2; Operate the operating component 34 to make the abutting component 31 not abut against or move away from the second window frame 2, adjust the position of the second window frame 2 relative to the first window frame 1, and make the second window frame 2 to a suitable position; release the operating component 34, and under the action of the elastic component 32, the abutting component 31 abuts against the second window frame 2, and the second window frame 2 can be locked to the first window frame 1.

[0029] Furthermore, the first window frame 1 and the second window frame 2 together form an installation cavity 4, and the installation cavity 4 is provided with an abutment member 31 and an elastic member 32; The first window frame 1 has a first sliding structure 114 in the mounting cavity 4, and the second window frame 2 has a second sliding structure 213 in the mounting cavity 4. The first sliding structure 114 and the second sliding structure 213 are interlocked and slide in cooperation. The extension direction of the first sliding structure 114 is parallel to the length direction of the first window frame 1, and the extension direction of the second sliding structure 213 is parallel to the length direction of the second window frame 2. Through the cooperation of the first sliding structure 114 and the second sliding structure 213, the second window frame 2 is limited, so that the locking mechanism 3 can quickly and stably switch between the locked state and the unlocked state.

[0030] Preferably, there are two first sliding structures 114; the two first sliding structures 114 are arranged opposite to each other on both sides of the abutment 31 in the width direction of the first window frame 1; Two second sliding structures 213 are provided; the two second sliding structures 213 are arranged opposite to each other on both sides of the abutment 31 in the width direction of the second window frame 2; The two first sliding structures 114 and the two second sliding structures 213 are matched in a one-to-one correspondence.

[0031] In addition, the first window frame 1 is also provided with a third sliding structure 115, and there are two third sliding structures 115; the two third sliding structures 115 are arranged opposite to each other on both sides of the mounting cavity 4 in the width direction of the first window frame 1, and the two third sliding structures 115 are respectively arranged close to the two edges in the width direction of the first window frame 1. The second window frame 2 is also provided with a fourth sliding structure 214, and there are two fourth sliding structures 214; the two fourth sliding structures 214 are arranged opposite to each other on both sides of the mounting cavity 4 in the width direction of the second window frame 2, and the two fourth sliding structures 214 are respectively arranged close to the two edges in the width direction of the second window frame 2. The two third sliding structures 115 and the two fourth sliding structures 214 are in a one-to-one correspondence and mutually embedded sliding fit; the extension direction of the third sliding structure 115 is parallel to the length direction of the first window frame 1, and the extension direction of the fourth sliding structure 214 is parallel to the length direction of the second window frame 2. Thus, the first sliding structure 114 and the second sliding structure 213 are fitted together, and the third sliding structure 115 and the fourth sliding structure 214 are fitted together; this enhances the overall stability of the first window frame 1 and the second window frame 2, and allows the sliding structures to fit tightly during installation, avoiding the problem of reduced sealing performance caused by loose fitting structures in traditional designs.

[0032] Specifically, the abutting member 31 is an abutting block, the elastic member 32 is a spiral spring, and the top member 33 is a top rod; one end of the top member 33 near the abutting member 31 passes through the elastic member 32; the first window frame 1 protrudes in a direction away from the second window frame 2 to form a first recess 112, and the second window frame 2 protrudes in a direction away from the first window frame 1 to form a second recess 211. The first recess 112 and the second recess 211 are positioned correspondingly to form the mounting cavity 4; the first sliding structure 114 and the third sliding structure 115 are both sliding grooves, and the second sliding structure 213 and the fourth sliding structure 214 are both sliding rails; The first cavity 112 includes a first cavity bottom wall and a first cavity side wall. The first cavity bottom wall is located away from the second cavity 211. There are two first cavity side walls. In the width direction of the first window frame 1, the two first cavity side walls are arranged opposite to each other on both sides of the first cavity bottom wall. The first cavity side wall is provided with a limiting rib 113. The limiting rib 113 and the first cavity bottom wall together form a first sliding structure 114. The second cavity 211 includes a second cavity bottom wall and a second cavity side wall. The second cavity bottom wall is disposed away from the first cavity 112. There are two second cavity side walls, which are disposed opposite to each other on both sides of the second cavity bottom wall in the width direction of the second window frame 2. The second cavity side wall is provided with a support member 212, which extends into the first cavity 112 and forms a second sliding structure 213 in the first cavity 112. Preferably, the support member 212 and the second sliding structure 213 form an inverted T-shaped structure, and the third sliding structure 115 and the fourth sliding structure 214 are both cylindrical or both are inverted T-shaped structures.

[0033] The following describes the overall structure of the first window frame 1 and the second window frame 2. The first window frame 1 includes a first window panel 11. The first window panel 11 has a first bending structure 12 on each of its two edges in the width direction. The first bending structure 12 bends away from the second window frame 2. The second window frame 2 includes a second window panel 21. The second window panel 21 has a second bending structure 22 on each of its two edges in the width direction. The second bending structure 22 bends away from the first window frame 1. The second window panel 21 is movably disposed on the first window panel 11, and the elastic member 32 and the abutting member 31 are disposed between the first window panel 11 and the second window panel 21.

[0034] Thus, the first bending structure 12 and the second bending structure 22 are independently opposite and unwrapped. This design can eliminate the step difference on both sides of the width direction of the first window frame 1, so that the window can be sealed without the need for additional sponge on both sides, thereby improving the sealing performance of the product.

[0035] In summary, the locking mechanism 3 enables rapid locking and unlocking of the second window frame 2 and adjustment of its position relative to the first window frame 1, solving the problems of difficult assembly and disassembly, low efficiency, and narrow applicability of existing window frame components. In the middle of the first window frame 1 and the second window frame 2, the first sliding structure 114 and the second sliding structure 213 are embedded and cooperate, as are the third sliding structure 115 and the fourth sliding structure 214. On both sides of the first window frame 1 and the second window frame 2 in the width direction, the first bending structure 12 and the second bending structure 22 are independently opposite and unencased, avoiding the height difference problem on both sides of the first window frame 1 and the second window frame 2 in the width direction in traditional designs. This design not only improves the sealing performance of the window but also reduces the need for additional sealing materials (such as sponge) due to height differences, lowering material costs and maintenance difficulty. Simultaneously, it enhances the product's aesthetics, reliability, sealing performance, and economy, improving the user experience.

[0036] This embodiment also provides a portable air conditioner, including an exhaust pipe and the window frame assembly described above; the second window frame 2 is provided with a mounting hole, and the exhaust pipe passes through the mounting hole for connecting the portable air conditioner and the outside.
