[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0034] The present invention discloses a locking device for a saddle-type window air conditioner, referring to Figure 1 The saddle-type window air conditioner 600 includes an indoor part 610, an outdoor part 620 and a connecting part 630. The connecting part 630 is used to connect the indoor part 610 and the outdoor part 620 together. The indoor part 610 is located on the indoor side, and the outdoor part 620 is located on the outdoor side. The connecting part 630 separates the indoor part 610 from the outdoor part 620, effectively reducing indoor noise. In addition, the indoor part 610 and the outdoor part 620 are located on the same side of the connecting part 630. When the saddle-type window air conditioner 600 is installed, the connecting part 630 is located on the window, and the indoor part 610 and the outdoor part 620 are respectively located below the window to avoid blocking sunlight and improve user comfort.

[0035] The connection part 630 includes an indoor connection box 631 and an outdoor connection box 632 which are nested with each other. The indoor connection box 631 is connected to the indoor part 610, and the outdoor connection box 632 is connected to the outdoor part 620. A sliding member is provided between the indoor connection box 631 and the outdoor connection box 632. The indoor connection box 631 and the outdoor connection box 632 reciprocate along the sliding member to achieve an adjustable length of the connection part 630 for easy installation. In this embodiment, the sliding member is provided on the left and right sides of the indoor connection box 631 and the outdoor connection box 632. Of course, in other embodiments, the sliding member can also be provided on the upper and lower sides of the indoor connection box 631 and the outdoor connection box 632.

[0036] The indoor connection box 631 can be located on the outside of the outdoor connection box 632, or on the inside of the outdoor connection box 632. As a preferred embodiment, the indoor connection box 631 is arranged on the inside of the outdoor connection box 632. In this way, when the window air conditioner 600 is installed, foreign objects such as dust and flying insects on the outdoor side can be prevented from entering the interior of the connecting part 630 through the gap between the indoor connection box 631 and the outdoor connection box 632.

[0037] In this embodiment, the sliding part adopts a finished slide rail 633 that can be purchased on the market. One side of the slide rail 633 is fixedly connected to the outer wall of the indoor connection box 631, and the other side of the slide rail 633 is fixedly connected to the inner wall of the outdoor connection box 632. By dragging the indoor part 610 or the outdoor part 620, the indoor connection box 631 and the outdoor connection box 632 can be moved relative to each other along the slide rail 633 to adjust the length of the connection part 630.

[0038] The installation steps of the saddle window air conditioner 600 are:

[0039] stretching the connecting portion 630 to its longest dimension;

[0040] The saddle-type window air conditioner 600 is placed on the window, with the connecting portion 630 abutting against the window frame, the indoor portion 610 being located on the indoor side, and the outdoor portion 620 being located on the outdoor side;

[0041] The size of the connecting portion 630 is shortened so that the indoor portion 610 abuts against the indoor wall, and the outdoor portion 620 abuts against the outdoor wall.

[0042] The function of the locking device of this embodiment is: when the saddle-type window air conditioner 600 is installed on the window and the connecting part 630 is adjusted to a length suitable for the window, the locking device is used to lock the connecting part 630 so that the connecting part 630 cannot be extended any further.

[0043] The structural diagram of the locking device is shown in the figure below. Figure 2 , Figure 3 , Figure 4 and Figure 6The locking device includes a lock box assembly 300, a lock column assembly 200 and a paddle assembly 100, wherein the lock box assembly 300 is connected to the indoor connection box 631 or the outdoor connection box 632 located on the inner side; the lock column assembly 200 is connected to the outdoor connection box 632 or the indoor connection box 631 located on the outer side, and includes a lock column 210; the paddle assembly 100 includes a paddle 110 arranged in the lock box assembly 300, and the paddle 110 is provided with a through hole 113, and the lock column 210 is penetrated in the through hole 113. When the lock column 210 contacts the side wall of the through hole 113, friction is generated, and the locking device is in a locked state, specifically a one-way locking state, that is, the lock column 210 can only move in one direction relative to the through hole 113 along its length direction, and at this time, the indoor connection box 631 and the outdoor connection box 632 can only move in one direction, and the connecting portion 630 can only shorten and cannot extend, so as to achieve the locking of the saddle-type window air conditioner 600 after installation. When the lock column 210 does not contact the side wall of the through hole 113, the friction between the lock column 210 and the through hole 113 disappears, the locking of the locking device is released, and the locking device is in a free telescopic state, that is, the lock column 210 can move in two directions relative to the through hole 113 along its length direction, and at this time, the indoor connection box 631 and the outdoor connection box 632 can move toward or away from each other, and the connecting portion 630 can freely extend or shorten.

[0044] For the convenience of the following description, this embodiment is described by taking the indoor connection box 631 as being located inside the outdoor connection box 632 as an example. At this time, the lock box assembly 300 is connected to the indoor connection box 631, and the lock column assembly 200 is connected to the outdoor connection box 632. Figure 2 In order to clearly express the structure of the locking device, the upper side walls of the indoor connection box 631 and the outdoor connection box 632 are hidden and not shown.

[0045] The lock box assembly 300 includes an upper box cover 310 and a lower box cover 320. A hollow cavity is formed between the upper box cover 310 and the lower box cover 320. The structural schematic diagram of the upper box cover 310 is shown in FIG. Figure 8 , the structural diagram of the lower box cover 320 is shown in FIG. Fig. 9The upper box cover 310 includes an upper box cover body 311 and an upper box cover side wall 312 arranged around the upper box cover body 311, and the lower box cover 320 is a plate-like structure adapted to the shape of the upper box cover body 311. An upper threaded column 314 is provided on the upper box cover body 311, and a lower threaded column 321 is correspondingly provided on the lower box cover 320. The upper surface of the upper box cover body 311 is tightly attached to the inner surface of the upper side wall of the indoor connection box 631. The screws are simultaneously inserted into the upper side wall, the upper threaded column 314 and the lower threaded column 321 of the indoor connection box 631 to fix the lock box assembly 300 to the indoor connection box 631. In order to make the lock box assembly 300 more reliably and stably connected, the number of the upper threaded column 314 is four, which are arranged at the four corners of the upper box cover body 311, and the number of the lower threaded column 321 is also four, which are arranged at the four corners of the lower box cover 320.

[0046] As a preferred embodiment, in order to facilitate the installation of the lock box assembly 300, a positioning column 322 is provided on the lower box cover 320, and a positioning hole 315 is correspondingly provided on the side of the upper box cover body 311 facing the lower box cover 320. During installation, the positioning column 322 is first inserted into the positioning hole 315, and the positioning column 322 and the positioning hole 315 are interference fit. At this time, the upper box cover 310 and the lower box cover 320 are connected as a whole, and the upper threaded column 314 and the lower threaded column 321 are facing each other. Then the lock box assembly 300 can be fixed to the indoor connection box 631 by screws.

[0047] The paddle assembly 100 includes a paddle 110, a first connecting member 120 and a buckle 130, wherein one end of the first connecting member 120 is connected to the paddle 110, and the other end of the first connecting member 120 is connected to the buckle 130. When the locking function of the locking device needs to be released, the buckle 130 is pulled, and the buckle 130 drives the first connecting member 120 to move, and the first connecting member 120 drives the paddle 110 to move. With the movement of the paddle 110, the lock column 210 and the side wall of the through hole 113 are converted from a contact state to a non-contact state, and the friction between the two disappears.

[0048] As a preferred embodiment, in order to facilitate operation, the handle 130 is arranged on the upper part of the indoor part 610, referring to Figure 1 When the length of the connecting portion 630 needs to be adjusted, the user can simply pull the handle 130 on the indoor side.

[0049] After the buckle 130 is released, the lock column 210 and the side wall of the through hole 113 are converted from a non-contact state to a contact state, and the locking device returns to the locked state. Therefore, when the length of the connecting portion 630 needs to be shortened, the buckle 130 needs to be pulled all the time. In the actual installation operation, since the buckle 130 is provided on the indoor portion 610, the hand can simultaneously pull the buckle 130 while holding and dragging the indoor portion 610 to adjust the length of the connecting portion 630, thereby improving the convenience of operation.

[0050] The first connecting member 120 is a long rod-shaped structure. The end of the first connecting member 120 close to the buckle 130 is a U-shaped bending structure. The lower end of the buckle 130 is provided with a clamping groove 131. The U-shaped bending structure is engaged with the clamping groove 131 by interference fit, so as to realize the fixed connection between the buckle 130 and the first connecting member 120. The structure is simple and easy to install. The end of the first connecting member 120 close to the paddle 110 can be fixedly connected to the paddle 110 by welding, screwing, etc.

[0051] The lock column assembly 200 includes a lock column 210 and a second connecting member 220. The second connecting member 220 is disposed at one end of the lock column 210. The second connecting member 220 is connected to the outdoor connection box 632 or the indoor connection box 631 located outside. In this embodiment, the indoor connection box 631 is located inside the outdoor connection box 632 as an example. At this time, the second connecting member 220 is fixedly connected to the outdoor connection box 632 to fix the lock column assembly 200 to the outdoor connection box 632. Specifically, the second connecting member 220 is a U-shaped bending structure, including a first bending section, a second bending section and a third bending section connected in sequence. The first bending section is fixedly connected to one end of the lock column 210 by screws, and the third bending section is fixedly connected to the upper side wall of the outdoor connection box 632 by screws.

[0052] The structural diagram of the paddle 110 is shown in FIG. Figure 7 The paddle 110 is a two-stage type, including a first paddle 111 and a second paddle 112. The first connecting member 120 is fixedly connected to the first paddle 111, and a through hole 113 is provided on the second paddle 112. The edge size of the through hole 113 is larger than the edge size of the lock column 210. When the second paddle 112 is tilted relative to the lock column 210, the lock column 210 contacts the side wall of the through hole 113, and the lock column 210 is locked by the contact friction between the two, that is, the locking device is locked. When the buckle 130 is pulled, the second paddle 112 moves under the linkage action of the first connecting member 120 until the through hole 113 is no longer in contact with the lock column 210. At this time, the friction between the two disappears, and the lock column 210 can move freely, that is, the locking of the locking device is released.

[0053] For the sake of convenience, the end of the second paddle 112 close to the first paddle 111 is defined as the second paddle first end E, and the end of the second paddle 112 away from the first paddle 111 is defined as the second paddle second end F. The above “the second paddle 112 is inclined relative to the lock cylinder 210” should be understood as the distance between the second paddle first end E and the indoor part 610 is not equal to the distance between the second paddle second end F and the indoor part 610. In this embodiment, refer to Figure 6 , the first end E of the second paddle is farther away from the indoor part 610 than the second end F of the second paddle.

[0054] As a preferred embodiment, in order to increase the friction between the lock column 210 and the through hole 113 and make the locking function of the locking device more effective and reliable, the lock column 210 is configured as a flat structure, and the through hole 113 is also correspondingly configured as a flat through hole. When the second paddle 112 is tilted relative to the lock column 210, the left and right side walls of the lock column 210 and the left and right side walls of the through hole 113 generate a sufficiently large friction force through line contact, so that relative movement cannot occur between the lock column 210 and the through hole 113, thereby achieving the locking of the locking device.

[0055] In order to further increase the contact friction between the locking column 210 and the through hole 113, refer to Figure 5 The lock column 210 is set to be an "I"-shaped structure with a flat middle and wide sides. Figure 7 The through hole 113 is also set to an "I"-shaped structure with a flat middle and wide sides, which can increase the contact linear length between the left and right side walls of the lock column 210 and the left and right side walls of the through hole 113, thereby increasing the contact friction between the two.

[0056] The lock box assembly 300 is further provided with a spring 400, one end of which is in contact with the second paddle 112, and the spring 400 is in a compressed state. The second paddle 112 is kept in an inclined state with respect to the lock column 210 under the elastic force of the spring 400, that is, the locking device is in a locked state. Figure 6The spring 400 is located on the side of the second paddle 112 close to the indoor part 610 and is arranged on the left and right sides of the lock column 210. One end of the spring 400 is fixedly mounted on the upper cover 310, and the other end of the spring 400 is in contact with or fixedly connected to the second paddle 112, that is, one spring 400 is in contact with or fixedly connected to the first end E of the second paddle, and the other spring 400 is in contact with or fixedly connected to the second end F of the second paddle. When the buckle 130 is not subjected to force, the second paddle 112 is tilted relative to the lock column 210, and the left and right side walls of the through hole 113 contact the left and right side walls of the lock column 210 to generate friction. At this time, the spring 400 is in a compressed state, and the spring 400 gives the second paddle 112 a force in the direction away from the indoor part 610, so that the second paddle 112 can always maintain an inclined state with the lock column 210, that is, the locking device is always in a locked state. The two separate springs 400 make the friction force between the second paddle 112 and the lock column 210 more uniform. When the buckle 130 is stressed, the buckle 130 drives the first connecting member 120 to move toward the indoor part 610, and the paddle 110 also moves toward the indoor part 610 under the action of the first connecting member 120, so that the second paddle 112 and the lock column 210 are transformed from an inclined state to a vertical state. At this time, the side wall of the through hole 113 and the side wall of the lock column 210 are not in contact, and the friction between the two disappears. The lock column 210 can reciprocate and telescope relative to the through hole 113 to facilitate the length adjustment of the connecting part 630. Here, "vertical state" should be understood as the distance between the first end E of the second paddle and the indoor part 610 and the distance between the second end F of the second paddle and the indoor part 610 are equal.

[0057] The locking device of this embodiment realizes one-way locking, and the locking column 210 can only move in one direction relative to the through hole 113 along its length direction, that is, only one-way movement can be generated between the indoor connection box 631 and the outdoor connection box 632, which is specifically reflected in that the connecting part 630 can only be shortened and cannot be extended. When the saddle-type window air conditioner 600 is installed on the window, since the indoor part 610 and the outdoor part 620 are respectively placed on the inner and outer sides of the wall below the window, although the connecting part 630 can be shortened, it cannot be shortened under the blocking effect of the wall, that is, the window air conditioner 600 is locked. Corresponding to "the connecting part 630 can only be shortened and cannot be extended", it is reflected in the locking device that when the position of the through hole 113 is not moved, the locking device, under the action of the spring force, the locking column 210 can only move toward the direction close to the indoor part 610, but cannot move toward the direction close to the outdoor part 620.

[0058] To facilitate the installation of spring 400, refer to Figure 8A spring installation cavity 313 is provided on the upper box cover body 311, and the spring 400 is limited between the spring installation cavity 313 and the second paddle 112, and is not easy to fall off. At the same time, the spring installation cavity 313 also plays a certain guiding role in the telescopic movement of the spring 400.

[0059] In order to prevent the spring 400 from sagging under the action of gravity and affecting the reliability of the entire locking device, a column 324 is provided on the lower box cover 320. The column 324 is located directly below the spring 400. The free end of the column 324 abuts against the spring 400, playing a certain supporting role for the spring 400.

[0060] Reference Figure 6 The lock box assembly 300 is also provided with a stop pin 500, which abuts against the second paddle 112. The stop pin 500 and the spring 400 are respectively arranged on both sides of the second paddle 112. Specifically, the stop pin 500 is arranged on one side of the second paddle 112 close to the outdoor portion 620 and located at the second end F of the second paddle. The lower box cover 320 is provided with a stop pin installation hole 323, referring to Fig. 9 , the stop pin 500 is inserted into the stop pin installation hole 323 with interference fit. When the buckle 130 is not subjected to force, the second paddle 112 is tilted relative to the lock column 210, and the spring 400 compresses and gives the second paddle 112 a force in a direction away from the indoor part 610. The first end E of the second paddle can remain motionless under the action of the first connecting member 120 and the buckle 130. In order to maintain the tilted state of the second paddle 112 relative to the lock column 210, the second end F of the second paddle needs to be able to remain motionless under the action of the spring force. The stop pin 500 is hereby used to prevent the second paddle 112 from being displaced under the action of the spring force, thereby maintaining the tilted state of the second paddle 112 relative to the lock column 210. When the buckle 130 is subjected to force, the paddle 110 moves toward the direction close to the indoor part 610 under the action of the first connecting member 120. At this time, the first end E of the second paddle moves toward the direction close to the indoor part 610 under the linkage action of the first connecting member 120, and the second end F of the second paddle rotates with the stop pin 500 as the rotation point until the second paddle 112 rotates until the friction between the through hole 113 and the lock column 210 disappears.

[0061] The upper cover side wall 312 is provided with a first opening 316, a second opening 317 and a third opening 318, and the second opening 317 and the third opening 318 are arranged opposite to each other. When the locking device is assembled, the paddle 110 is inserted into the first opening 316, specifically, the first paddle 111 is inserted into the first opening 316, and the lock column 210 is inserted into the second opening 317 and the third opening 318 at the same time.

[0062] The present invention further discloses a saddle-type window air conditioner 600, in which the locking device disclosed in this embodiment is provided.
