In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or the solution where A and B are satisfied simultaneously. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0038] In the prior art, for a split air conditioner that facilitates personal installation by users, it uses flexible refrigerant pipes to connect the indoor heat exchanger of the indoor unit of the air conditioner and the outdoor heat exchanger of the outdoor unit of the air conditioner, and injects refrigerant into the refrigerant circuit before the equipment leaves the factory. In this way, when the user installs the equipment by himself / herself, only the indoor unit and the outdoor unit of the air conditioner need to be fixed respectively, without the need to assemble the refrigerant pipes and add refrigerant, thereby reducing the installation difficulty and realizing personal installation by the user.

[0039] The mounting bracket for installing the outdoor unit of the air conditioner generally includes a bolt assembly, a main bracket, and a top wall bracket. One end of the top wall bracket is connected to the main bracket and the other end abuts against the outer wall; one end of the main bracket extends out of the window and is used to support the outdoor unit of the air conditioner, and the other end needs to be installed on the installation position by means of the bolt assembly.

[0040] In the prior art, in order to facilitate the installation of the mounting bracket, the bolt assembly used usually includes a foot seat and a bolt. The free end of the bolt is generally provided with an internal thread to cooperate with the screw on the foot seat, so that the foot seat and the bolt are fixed, and the foot seat is driven to move by the bolt, and then the other end of the main bracket of the mounting bracket is installed on the installation position. Such a bolt processing process is complex and not conducive to production and manufacturing.

[0041] In order to reduce the process difficulty of the bolt, the present utility model proposes a bolt assembly 100.

[0042] Please refer to Figures 1 to 3, in an embodiment of the present utility model, the bolt assembly 100 is used to install the mounting bracket 10. The mounting bracket 10 is provided with a first internal thread hole 214. The bolt assembly 100 includes a stud 110 and a foot seat 120. The stud 110 includes a connected first external thread section 111 and a second external thread section 112. The diameter of the first external thread section 111 is greater than or equal to the diameter of the second external thread section 112. The first external thread section 111 is used to cooperate with the first internal thread hole 214. The foot seat 120 is provided with a second internal thread hole 121, and the second internal thread hole 121 is adapted to the second external thread section 112.

[0043] Specifically, the mounting bracket 10 is provided with a clamping groove 211. The clamping groove 211 has a first groove wall 212 and a second groove wall 213 arranged oppositely. The first internal thread is provided on the first groove wall 212.

[0044] The technical solution of the present utility model is to set a connected first external thread section 111 and a second external thread section 112 on the stud 110. The foot seat 120 is placed in the clamping groove 211. The first external thread section 111 is screwed into the first internal thread hole 214, and the second external thread section 112 is screwed into the second internal thread hole 121 of the foot seat 120. A clamping space 215 is formed between the foot seat 120 and the second groove wall 213. It can be understood that the first external thread section 111 is screwed in the direction close to the second groove wall 213, thereby driving the foot seat 120 to move in the direction close to the second groove wall 213, achieving the effect of reducing the clamping width of the clamping space 215, and then clamping and installing the mounting bracket 10 to the installation position. When it is necessary to disassemble the mounting bracket 10, the first external thread section 111 is screwed out in the direction away from the second groove wall 213, thereby driving the foot seat 120 to move in the direction away from the second groove wall 213, achieving the effect of increasing the clamping width of the clamping space 215, and then disassembling the mounting bracket 10 from the installation position. Generally, the thread section of the stud in the market for cooperating with the foot seat 120 is generally provided with an internal thread. This solution is beneficial to reducing the processing technology difficulty compared with the solution of setting an internal thread on the stud, thus being beneficial to production and manufacturing. Specifically, the stud 110 of this solution is the stud of the bolt in the prior art. It can be seen that this solution is beneficial to reducing the process difficulty of the bolt in the bolt assembly 100.

[0045] It should be noted that the installation position can be a tabletop, a window frame 21, a support frame, etc.

[0046] Secondly, in the first embodiment, the diameter of the first external thread section 111 is greater than the diameter of the second external thread section 112. This can facilitate the formation of a limiting step between the first external thread section 111 and the second external thread section 112, thereby limiting the second external thread section 112, restricting the length of the second external thread section 112 screwed into the second internal thread hole 121, and further avoiding interference between the second external thread section 112 and the installation position.

[0047] In the second embodiment, the diameter of the first external thread segment 111 is equal to the diameter of the second external thread segment 112. Compared with the solution in which the diameter of the first external thread segment 111 is larger than the diameter of the second external thread segment 112, the processing steps can be reduced and the process difficulty can be reduced, thereby achieving the effect of improving production efficiency.

[0048] Furthermore, the diameter of the first external thread section 111 ranges from 6 mm to 9 mm, and the diameter of the second external thread section 112 ranges from 4 mm to 7 mm, which can ensure the strength of the stud 110 while reducing the volume of the stud 110 .

[0049] In this embodiment, the diameter of the first external thread section 111 is 8 mm, and the diameter of the second external thread section 112 is 6 mm, which can further ensure the strength of the stud 110 while reducing the volume of the stud 110.

[0050] Furthermore, a hand-tightening portion 113 is provided at one end of the first external thread section 111 away from the second external thread section 112. The provision of the hand-tightening portion 113 facilitates the user to rotate the stud 110, making the rotation of the stud 110 more labor-saving. Of course, the present solution is not limited thereto, and in other embodiments, the hand-tightening portion 113 may not be provided, and when the stud 110 needs to be rotated or tightened, the stud 110 may be tightened with the aid of an external tool, such as but not limited to a pliers.

[0051] Among them, the hand-tightening part 113 includes two screw rods extending crosswise, and the extension directions of the two screw rods are respectively perpendicular to the stud 110; or, the hand-tightening part 113 is configured as a plum blossom handle; or the hand-tightening part 113 is configured as a butterfly handle; there is no restriction on the specific shape of the handle part, as long as it can drive the stud 110.

[0052] Reference Figure 6 Furthermore, the length of the second external thread segment 112 is less than or equal to the depth of the second internal thread hole 121; this can prevent the second external thread segment 112 from interfering with the installation position or even damaging the installation position.

[0053] Optionally, glue is provided between the first external thread section 111 and the first internal thread hole 214. It can be understood that when the stud 110 and the mounting bracket 10 are in a fastened state, glue is provided between the first external thread section 111 and the first internal thread hole 214, which can reduce the probability of the first external thread section 111 rotating relative to the first internal thread hole 214, thereby increasing the anti-loosening force of the bolt assembly 100.

[0054] Optionally, an adhesive is provided between the second external thread section 112 and the second internal thread hole 121. It can be understood that when the stud 110 and the mounting bracket 10 are in a fastened state, providing an adhesive between the second external thread section 112 and the second internal thread hole 121 can reduce the probability of the second external thread section 112 rotating relative to the second internal thread hole 121, thereby increasing the anti-loosening force of the bolt assembly 100.

[0055] Optionally, an adhesive is provided between the first external thread section 111 and the first internal thread hole 214, and an adhesive is also provided between the second external thread section 112 and the second internal thread hole. This can further increase the anti-loosening force of the bolt assembly 100.

[0056] Among them, the adhesive is configured as anaerobic glue. This is because anaerobic glue has excellent bonding strength after curing, can withstand large tensile and compressive forces, and its performance is very stable. If a user tries to twist it by hand, it is simply impossible to break the anti-loosening force of the anaerobic glue. Tools must be used, so its anti-loosening effect is very obvious. Moreover, anaerobic glue can still maintain stable performance in a high-temperature environment. Thus, even if the mounting bracket 10 is in a sun-exposed environment, it can still maintain excellent bonding strength. Of course, this solution is not limited to this. In other embodiments, the adhesive can also be configured as epoxy glue.

[0057] Referring to Figure 4 and Figure 5 , optionally, the bolt assembly 100 further includes an elastic pad 130, and the elastic pad 130 is provided on the side of the foot seat 120 away from the stud 110; the elastic pad 130 can buffer the vibration transmitted from the operation of the instrument on the mounting bracket 10 to between the bolt assembly 100 and the mounting position, and at the same time can also prevent material damage to the mounting position caused by the bolt assembly 100 being too tight. Of course, this solution is not limited to this. In other embodiments, the elastic pad 130 may not be provided.

[0058] Among them, the material of the elastic pad 130 is rubber. This is because a rubber pad can maintain stable performance within a wide temperature range and is not affected by extreme temperatures. This can make the elastic pad 130 less affected by the ambient temperature, which is beneficial to improving the service life of the elastic pad 130. More importantly, rubber has excellent elastic properties, which is beneficial to increasing the elastic force of the elastic pad 130, thereby improving the buffering force of the elastic pad 130. Of course, this solution is not limited to this. In other embodiments, the material of the elastic pad 130 can also be silicone or polyurethane.

[0059] Optionally, the footrest 120 is configured as a flange nut. Since the installation and disassembly of the flange nut are relatively simple, a large amount of time and labor costs can be saved. When repairing and replacing equipment components, the flange nut can be limited by external tools, such as but not limited to a hex wrench, so as to improve the installation efficiency of the mounting bracket 10. Of course, this solution is not limited to this. In other embodiments, the footrest 120 can also be configured as a columnar footrest 120, and an internal threaded hole is provided on the columnar footrest 120.

[0060] Referring to Figure 6 , further, the elastic pad 130 is sleeved on the flange ring 122 of the flange nut. Such an installation method is simple and is convenient for improving the installation efficiency of the bolt assembly 100.

[0061] Further, the elastic pad 130 is provided with an avoidance hole corresponding to the second internal threaded hole 121, so as to avoid the second external threaded section 112 from damaging the elastic pad 130.

[0062] Referring to Figure 1 and Figure 2 , the present utility model further provides a mounting bracket 10 for mounting an air conditioner outdoor unit 30. The mounting bracket 10 includes a bolt assembly 100, a main bracket 200, and a support bracket 300. The main bracket 200 includes a window mounting bracket 210 and a load-bearing bracket 220 that are connected. The window mounting bracket 210 is provided with a clamping groove 211. The clamping groove 211 has a first groove wall 212 and a second groove wall 213 that are oppositely arranged. The footrest 120 of the bolt assembly 100 is arranged in the clamping groove 211. The first internal threaded hole 121 is arranged on the first groove wall 212. A clamping space 215 is formed between the footrest 120 and the second groove wall 213. The clamping space 215 is used to clamp the window frame 21 on the window. The load-bearing bracket 220 extends to the outside of the window along the first direction. The air conditioner outdoor unit 30 is arranged on the upper side of the load-bearing bracket 220; the support bracket 300 is connected to the load-bearing bracket 220 and can adjust the connection position along the first direction to abut against the outer wall surface 20 and / or the window sill.

[0063] It should be noted that when fixing the mounting bracket 10, the first external threaded section 111 is screwed in the direction close to the second groove wall 213, so as to drive the footrest 120 to move in the direction close to the second groove wall 213, achieving the effect of reducing the clamping width of the clamping space 215, and further clamping and installing the mounting bracket 10 on the window frame 21. When it is necessary to disassemble the mounting bracket 10, the first external threaded section 111 is screwed out in the direction away from the second groove wall 213, so as to drive the footrest 120 to move in the direction away from the second groove wall 213, achieving the effect of increasing the clamping width of the clamping space 215, and further disassembling the mounting bracket 10 from the window frame 21.

[0064] Specifically, the first direction refers to a direction parallel or nearly parallel to the central axis of the window, and the window ledge width refers to the distance between the window frame 21 and the outer wall surface 20 in the first direction, as Figure 1 shown by the distance L in. It can be understood that the window ledge width is related to the thickness of the wall where the window is located and the installation position of the window frame 21 on the window. Therefore, the window ledge width may vary due to different buildings, resulting in the inability of the mounting bracket 10 with a fixed size specification to be well adapted to different window ledge widths.

[0065] In the technical solution of the present utility model, since the support bracket 300 can adjust its installation position on the main bracket 200 in the first direction, the position of the abutting end surface of the support bracket 300 relative to the window mounting bracket 210 is adjustable. That is, the distance between the abutting end surface of the support bracket 300 and the window mounting bracket 210 is adjustable, and this adjustable distance can be adapted to window ledges with different width dimensions. In this way, it is convenient for the user to adjust the installation position of the support bracket 300 on the main bracket 200 so that the support bracket 300 can abut well against the outer wall surface 20 and / or the window ledge, and the mounting bracket 10 can be well adapted to different window ledge widths.

[0066] Optionally, the support bracket 300 includes a first support portion 310 that connects to the load-bearing bracket 220 and extends downward, and the first support portion 310 can abut against the outer side surface of the window ledge. Specifically, the window ledge usually extends outward with a protruding window sill, and the widths of the protruding window sills of different buildings also vary in the first direction. At this time, the first support portion 310 can be used to abut against the outer end surface of the protruding window sill (i.e., the outer side surface of the window ledge) to achieve the installation and fixation of the support bracket 300.

[0067] In some other embodiments, in addition to the first support portion 310, the support bracket 300 further includes a second support portion 320. One end of the second support portion 320 is connected to the first support portion 310 and the other end can abut against the outer wall surface 20. At this time, the second support portion 320 can be used to abut against the outer wall surface 20 to achieve the installation and fixation of the support bracket 300, as Figure 1 and Figure 2 shown. Of course, in other embodiments, only the first support portion 310 can be provided without the second support portion 320; further optionally, the first support portion 310 directly extends downward obliquely in the direction close to the window mounting bracket 210, and its lower end can directly abut against the outer wall surface 20. At this time, either the side surface of the first support portion 310 can be used to abut against the outer side surface of the window ledge with a larger width, or the lower end portion of the first support portion 310 can be used to abut against the outer wall surface 20.

[0068] In some other embodiments, optionally, the first support portion 310 and the second support portion 320 are detachably connected. In this way, the user can flexibly adjust the structural form of the support bracket 300 according to the actual situation of the window ledge, that is, choose to use the first support portion 310 to abut against the window ledge, or choose the second support portion 320 to abut against the outer wall surface 20, so as to better and more conveniently adapt to different forms of window ledges. Of course, in other embodiments, the first support portion 310 and the second support portion 320 may also be fixedly connected to each other; or, the first support portion 310 and the second support portion 320 are integrally formed.

[0069] The present utility model further provides an air conditioner, which includes an outdoor unit 30 of the air conditioner and a mounting bracket 10. The specific structure of the mounting bracket 10 refers to the above embodiments. Since this air conditioner adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one. Among them, the outdoor unit 30 of the air conditioner is arranged on the upper side of the load-bearing bracket 220 of the mounting bracket 10.

[0070] Optionally, the air conditioner includes an indoor unit of the air conditioner and an outdoor unit 30 of the air conditioner. The mounting bracket 10 is used for installing the outdoor unit 30 of the air conditioner; the indoor unit of the air conditioner and the outdoor unit 30 are connected by a refrigerant hose assembly, and the refrigerant hose assembly is pre-filled with refrigerant; it can be understood that this air conditioner is a split-type air conditioner that is convenient for users to install personally. It uses a refrigerant hose assembly to connect the indoor-side heat exchanger of the indoor unit of the air conditioner and the outdoor-side heat exchanger of the outdoor unit 30 of the air conditioner, and injects refrigerant into the refrigerant circuit before the equipment leaves the factory. In this way, when the user installs the equipment by himself, he only needs to fix the indoor unit of the air conditioner and the outdoor unit 30 respectively, without the need to assemble the refrigerant pipes and fill the refrigerant, thereby reducing the installation difficulty and realizing personal installation by the user. However, this design is not limited thereto. In other embodiments, the air conditioner of the present utility model may also be an ordinary split-type air conditioner.

[0071] Among them, the refrigerant hose assembly may be a flexible refrigerant pipe and a sleeve sleeving the flexible refrigerant pipe, or may include any two of a refrigerant pipe, a drain pipe, and an energized wire, and a sleeve sleeving the two at the same time, or may be a sleeve sleeving the refrigerant pipe, the drain pipe, the energized wire, and the three at the same time, for convenient connection.

[0072] Further, the compressor of the air conditioner is arranged in the indoor unit of the air conditioner, which can reduce the weight of the outdoor unit, thus facilitating the installation of the outdoor unit.

[0073] Optionally, the air conditioner is provided with a noise reduction structure corresponding to the compressor, so as to reduce the noise of the compressor installed in the indoor unit of the air conditioner.

[0074] The above are only exemplary embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
