In addition, the terms “first” and “second” are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance. 
     The present invention discloses an auxiliary mounting device for a saddle-type window air conditioner, applied to a mounting process of a saddle-type window air conditioner. With reference to  FIG. 1 , a saddle-type window air conditioner  20  includes an indoor part  21 , an outdoor part  23  and a connecting part  22 . The indoor part  21  is located on an indoor side and below a window. The outdoor part  23  is located on an outdoor side and below the window. The connecting part  22  is configured to connect the indoor part  21  and the outdoor part  23 , and the overall appearance of the window air conditioner is in an inverted U-shaped structure. The connecting part  22  is available in two forms: retractable and non-retractable. When the retractable mode is used, the connecting part  22  has an adjustable length to adapt to windows of different sizes. After the saddle-type window air conditioner  20  is mounted to the window, the connecting part  22  is located on the window, and the indoor part  21  and the outdoor part  23  are both located below the window, which can prevent the window air conditioner from blocking sunlight. In this embodiment, preferably, the connecting part  22  is in a retractable mode. When mounting the saddle-type window air conditioner  20 , first, the length of the connecting part  22  is stretched, and the stretched saddle-type window air conditioner  20  is moved onto the window such that the indoor part  21  is located on the indoor side and the outdoor part  23  is located on the outdoor side; then the saddle-type window air conditioner  20  is made to fall down such that the connecting part  22  is located on the window; and finally, the length of the connecting part  22  is adjusted to adapt to the corresponding window size. 
     With reference to  FIG. 2  to  FIG. 5 , the auxiliary mounting device  10  for the saddle-type window air conditioner includes a base  11  and a bolt  12 . The base  11  is located below the connecting part  22 , and a certain distance d is formed between the base  11  and the connecting part  22 . One end of the bolt  12  is connected to the base  11 , and the other end of the bolt  12  runs through the connecting part  22  and is screwed with the connecting part  22 . At the time of mounting and use, the auxiliary mounting device  10  is fixedly mounted onto the saddle-type window air conditioner  20 , the distance d is formed between the base  11  and a lower surface of the connecting part  22 , and a lower surface of the base  11  is on the same plane or nearly on the same plane as a lower surface of the indoor part  21  and a lower surface of the outdoor part  23 . The saddle-type window air conditioner  20  together with the auxiliary mounting device  10  is moved onto the window, and the base  11  is placed on the window, such that the indoor part  21  is located on the indoor side and the outdoor part  23  is located on the outdoor side. At this time, the bolt  12  is equivalent to an ejector rod, such that the connecting part  22  of the saddle-type window air conditioner  20  is kept at a height d from the base  11 , that is, the saddle-type window air conditioner  20  is kept at a certain height from the window. The bolt  12  is screwed, such that the bolt  12  is screwed out of the connecting part  22 , and the base  11  moves together with the bolt  12 . As the screw-out movement of the bolt  12 , the bolt  12  and the connecting part  22  move towards each other, and the connecting part  22  is gradually moves towards the direction close to the base  11 , that is, the distance d between the base  11  and the lower surface of the connecting part  22  gradually decreases, so as to realize the slow falling of the saddle-type window air conditioner  20 . The auxiliary mounting device  10  is simple in structure and convenient for operation. 
     In order to realize retractability of the connecting part  22 , the connecting part  22  includes an indoor connecting box  221  and an outdoor connecting box  222 . One end of the indoor connecting box  221  is fixedly connected to the indoor part  21  by means of screws, buckles or the like, and one end of the outdoor connecting box  222  is fixedly connected to the outdoor part  23  by means of screws, buckles or the like. As a preferred embodiment, the outdoor connecting box  222  is located on a periphery of the indoor connecting box  221 , to prevent outside dust, foreign matters and the like from entering the indoor through a gap between the indoor connecting box  221  and the outdoor connecting box  222 , and meanwhile to make the product more beautiful. One end of the bolt  12  runs through the connecting part  22 , that is, one end of the bolt  12  runs through and is disposed in the indoor connecting box  221  and the outdoor connecting box  222  at the same time. As a preferred embodiment, an upper side wall and a lower side wall of the indoor connecting box  221  are respectively provided with a first through hole  225  for the bolt  12  to run through. An upper side wall and a lower side wall of the outdoor connecting box  222  are respectively provided with an elongated hole  226  for the bolt  12  to run through, the elongated hole  226  extends and is arranged along a length direction L of the outdoor connecting box  222 , and the bolt  12  runs through and is disposed in the first through hole  225  and the elongated hole  226  at the same time. In this embodiment, when the connecting part  22  is extended and retracted to adjust the length dimension, a relative movement is generated between the indoor connecting box  221  and the outdoor connecting box  222 , to drive the bolt  12  to make a linear motion along the elongated hole  226 . The elongated hole  226  ensures that the bolt  12  can run through the connecting part  22 , and meanwhile can also prevent the bolt  12  from affecting the relative movement between the indoor connecting box  221  and the outdoor connecting box  222 , so as to realize that the length of the connecting part  22  can be adjusted. In the meanwhile, the fit between the bolt  12  and the elongated hole  226  also performs a certain guiding function on the relative movement between the indoor connecting box  221  and the outdoor connecting box  222 . 
     The elongated hole  226  has a first end and a second end. The end of the elongated hole  226  close to the indoor part  21  is defined as the elongated hole first end  2261 , and the end close to the outdoor part  23  is defined as the elongated hole second end  2262 . In order to further ensure that the bolt  12  does not affect the relative movement between the indoor connecting box  221  and the outdoor connecting box  222 , the elongated hole first end  2261  is set to be through with a side edge of the outdoor connecting box  222 . The “side edge of the outdoor connecting box  222 ” here refers to the side edge of the outdoor connecting box  222  close to the indoor part  21 . With reference to  FIG. 6  and  FIG. 7 , when the indoor connecting box  221  and the outdoor connecting box  222  move towards each other until the bolt  12  abuts against the elongated hole second end  2262 , the connecting part  22  has the smallest length at this time. When the indoor connecting box  221  and the outdoor connecting box  222  move away from each other, the bolt  12  moves from the elongated hole second end  2262  towards the direction of the elongated hole first end  2261 , and the length of the connecting part  22  is gradually stretched and lengthened. Since the elongated hole first end  2261  is through with the side edge of the outdoor connecting box  222  close to the indoor part  21 , the movement away from each other between the indoor connecting box  221  and the outdoor connecting box  222  is not affected by the length of the elongated hole  226 . 
     The first through hole  225  is provided with a first shaft sleeve  224  facing an inside of the indoor connecting box  221 , the first shaft sleeve  224  has an internal thread, and the bolt  12  is screwed with the internal thread, so as to realize screw connection between the bolt  12  and the connecting part  22 . The first shaft sleeve  224  is disposed inside the indoor connecting box  221 , which may also prevent the first shaft sleeve  224  from affecting the relative movement between the indoor connecting box  221  and the outdoor connecting box  222 . 
     In order to make the product beautiful, in this embodiment, the connecting part  22  further includes a decorative hood  223 . The decorative hood  223  is disposed on a periphery of the outdoor connecting box  222  to block a connecting structure between the indoor connecting box  221  and the outdoor connecting box  222 . The bolt  12  runs through and is disposed in the indoor connecting box  221  and the outdoor connecting box  222 , and meanwhile also runs through and is disposed in the decorative hood  223 . The decorative hood  223  is provided with a is second through hole  227  corresponding to the first through hole  225 , and the bolt  12  runs through the second through hole  227 . When the indoor connecting box  221  and the outdoor connecting box  222  move relatively to adjust the length, the decorative hood  223  may further block the elongated hole  226 . In order to facilitate the expression of the connecting structure between the bolt  12  and the indoor connecting box  221  and the outdoor connecting box  222 , the decorative hood  223  is omitted in  FIG. 6  and  FIG. 7 . 
     The second through hole  227  located in an upper part of the decorative hood  223  is detachably provided with a cover (not shown in figures). When the bolt  12  is screwed out and demounted from the connecting part  22 , the cover seals the second through hole  227 , so as to prevent outside dust, foreign matters and the like from entering the inside of the connecting part  22  through the second through hole  227 . The cover is an elastic rubber cover, and the rubber cover is connected to the second through hole  227  by way of interference fit, and thus, the rubber cover is simple in structure and convenient for mounting and demounting. 
     One side of the base  11  facing the connecting part  22  is provided with a second shaft sleeve  111 , that is, an upper surface of the base  11  is provided with the second shaft sleeve  111 , the second shaft sleeve  111  is an elastic rubber member, and the lower end of the bolt  12  is connected to the second shaft sleeve  111  by way of interference fit. When the bolt  12  runs into the connecting part  22  from top to bottom, the lower end of the bolt  12  moves downward to be inserted into the second shaft sleeve  111 , so as to realize the fixed connection between the bolt  12  and the base  11 . When the bolt  12  is screwed out from bottom to top, the base  11  moves upward along with the bolt  12 . When the base  11  moves along with the bolt  12  to abut against the lower surface of the connecting part  22 , the second shaft sleeve  111  is sequentially inserted into the second through hole  227 , the elongated hole  226  and the first through hole  225  located in a lower part of the connecting part, and then is screwed upward out of the bolt  12 . The lower end of the bolt  12  is separated and extracted from the second shaft sleeve  111  until the bolt  12  is completely separated from the connecting part  22 . 
     As a preferred embodiment, the first shaft sleeve  224  is only disposed on an inner side of the upper side wall of the indoor connecting box  221 , so that the second shaft sleeve  111  can be smoothly inserted into the lower part of the connecting part  22 , so as to make the base  11  and the lower surface of the connecting part  22  attached to each other tightly and to make the saddle-type window air conditioner  20  more stable after being located on the window. At the same time, the inserted second shaft sleeve  111  also seals the second through hole  227 , the elongated hole  226  and the first through hole  225 , thereby preventing outside dust, foreign matters and the like from entering the inside of the connecting part  22 . 
     When the second shaft sleeve  111  is inserted into the connecting part  22 , as a preferred embodiment, an upper end surface of the second shaft sleeve  111  abuts against a lower end surface of the first shaft sleeve  224 , which can further prevent outside dust, foreign matters and the like from entering the inside of the connecting part  22 , and meanwhile can also prevent operating noise of the saddle-type window air conditioner  20  from coming out through middle holes of the first shaft sleeve  224  and the second shaft sleeve  111 , thereby being beneficial to reducing the operating noise. 
     A back plate of the indoor part  22  and a back plate of the outdoor part  23  are respectively provided with a limit piece (not shown in the figures) to limit the base  11 . When the bolt  12  is screwed in from top to bottom, the base  11  moves downward along with the bolt  12 . When the base  11  moves downward to abut against the limit piece, the base  11  moves into place. At this time, the screw-in action of the bolt  12  may be stopped, and the auxiliary mounting device  10  is mounted in place. 
     After the auxiliary mounting device  10  is fixedly mounted to the saddle-type window air conditioner  20 , the lower surface of the base  12  is retracted into the lower surface of the indoor part  21  and the lower surface of the outdoor part  23 . Thus, an inverted U-shaped structure with a smaller height is formed between the base  12  and the indoor part  21  and the outdoor part  23 . When the saddle-type window air conditioner  20  together with the auxiliary mounting device  10  is placed onto the window, the inverted U-shaped structure with a smaller height performs functions of locating and clamping to some extent, that is, the saddle-type window air conditioner  20  is preliminarily located and clamped onto the window. Therefore, when the saddle-type window air conditioner  20  slowly moves downward, it may be ensured that the indoor part  21  after falling down is located on the indoor side without generating movement interference with the window, and that the outdoor part  23  is located on the outdoor side without generating movement interference with the window. 
     This embodiment further discloses a mounting and use method of the is auxiliary mounting device for the saddle-type window air conditioner, including: 
     The bolt  12  is screwed into the connecting part  22  from top to bottom such that the lower end of the bolt  12  is connected to the base  11 , the upper end of the bolt  12  is screwed with the connecting part  22 , and a certain distance d is formed between the base  11  and the connecting part  22 . The base  11  gradually moves downward along with the screw-in movement of the bolt  12 , and the distance d between the base  11  and the connecting part  22  gradually increases, with reference to  FIG. 2 . 
     The saddle-type window air conditioner  20  together with the auxiliary mounting device  10  is moved onto a window, and the base  11  is located on the window such that the indoor part  21  is located on the indoor side and the outdoor part  23  is located on the outdoor side. 
     The bolt  12  is screwed out of the connecting part  22  from bottom to top, and the connecting part  22  gradually moves towards the direction close to the base  11  along with the screw-out movement of the bolt  12 . In other words, the connecting part  22  gradually moves downward along with the screw-out movement of the bolt  12 , that is, the overall saddle-type window air conditioner  20  gradually moves downward, and the distance d between the base  11  and the connecting part  22  gradually decreases, with reference to  FIG. 3 . 
     When the connecting part  22  moves downward to abut against the upper surface of the base  11 , the saddle-type window air conditioner  20  is mounted in place, and then, the bolt  12  is screwed out and demounted from the connecting part  22 , with reference to  FIG. 4 . 
     As a preferred embodiment, the mounting and use method further includes: 
     The cover is inserted into the second through hole  227  located in the upper part of the decorative hood  223 . 
     It should be illustrated finally that, the above embodiments are only used for illustrating the technical solutions of the present invention, and are not intended to limit the present invention. Although the present invention is illustrated in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that, modifications may still be made on the technical solutions recited in the foregoing embodiments, or equivalent replacements are made on part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions break away from the spirit and scope of the technical solution of the various embodiments of is the present invention.
