[0053] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to specific embodiments and drawings.

[0054] The terms used herein are merely used to describe specific embodiments, and are not intended to limit the present application. The terms "include", "contain" and the like used herein indicate the existence of the described features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0055] All terms used herein, including technical and scientific terms, have meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted to have meanings consistent with the context of the present specification, and should not be interpreted in an idealized or overly formal manner.

[0056] In the case of using expressions such as "at least one of A, B, and C", it is generally intended to mean A or B or C or any combination of A, B, and C, e.g. a system having at least one of A, B, and C should be interpreted to include a system having A alone, a system having B alone, a system having C alone, a system having both A and B, a system having both A and C, a system having both B and C, and / or a system having A, B, and C, etc. In the case of using expressions such as "at least one of A, B, or C", it is generally intended to mean A or B or C or any combination of A, B, and C, e.g. a system having at least one of A, B, and C should be interpreted to include a system having A alone, a system having B alone, a system having C alone, a system having both A and B, a system having both A and C, a system having both B and C, and / or a system having A, B, and C, etc.

[0057] Ceiling, i.e. ceiling decoration, includes base pieces (such as keels, etc.) and ceilings, and is suitable for being arranged on the top of home space, commercial space and public space, and has the effects of hiding pipelines, sound insulation, heat insulation and beautifying space, etc. Based on various requirements such as light weight, fireproof, sound absorption, heat insulation and beauty, some ceilings are made of materials with brittle texture (such as gypsum board, etc.) or internal loose texture (such as honeycomb board, etc.).

[0058] For some electrical equipment 1 (such as air conditioning device, projection device, monitoring device, etc.) which needs to be installed on the ceiling, when the electrical equipment 1 is hoisted on the ceiling 2, at present, a fixing piece (such as a screw, a screw and a nut, a bolt and a nut, etc.) is usually used to directly install the mounting part 11 of the electrical equipment 1 on the ceiling 2. When the fixing piece is assembled with the ceiling 2 with brittle texture, the part of the ceiling 2 connected with the fixing piece will be broken into small pieces, so that the inner diameter of the fixing hole 311 assembled with the fixing piece is irregularly widened, and thus effective connection cannot be formed. When the fixing piece is assembled with the ceiling 2 with internal loose texture, since there are many pores (i.e. hollow parts) in the ceiling 2, effective connection with the fixing piece cannot be formed, and thus the installation of the electrical equipment 1 is difficult.

[0059] Therefore, how to provide a hoisting mechanism and air conditioning device which can be used to install electrical equipment 1 regardless of the texture of the ceiling 2 has become a technical problem to be solved.

[0060] Figure 1 is a structure schematic view of the hoisting mechanism and the electrical equipment assembled according to the illustrative embodiment of the utility model.

[0061] The utility model provides a kind of hoisting mechanism, such as Figure 1As shown, the mounting hole 21 is applicable to set the electrical equipment 1 on the ceiling 2. The electrical equipment 1 has a mounting portion 11, which includes but is not limited to a plate-shaped structure configured as an L shape, one end of which is connected to the electrical equipment 1; the other end of which is penetrated downward by the mounting hole 21 and extends to the lower side of the ceiling 2 away from the mounting hole 21, and the part of the mounting portion 11 below the ceiling 2 has the mounting hole 21. Wherein, the mounting hole 21 can be formed on the base member (such as the keel), that is, a certain square area defined by the base member is missing a piece of the ceiling 2 as a whole; or the mounting hole 21 can be formed in the middle of a piece of the ceiling 2, that is, a hollow area is formed on the ceiling 2.

[0062] For the assembly of the above-mentioned electrical equipment 1 and the ceiling 2, the utility model provides a hoisting mechanism, and the hoisting mechanism will be described in the following embodiments.

[0063] Figure 2 It is a perspective view of the lifting appliance according to the illustrative embodiment of the utility model. Figure 3 It is Figure 2 It is a perspective view of the lifting appliance from another angle.

[0064] First embodiment

[0065] The first embodiment of the utility model will be described below, as Figures 1 to 3 As shown, the hoisting mechanism includes a lifting appliance 3 and a fixing member (not shown in the figure, which includes but is not limited to a screw). The lifting appliance 3 is arranged above the ceiling 2 and has adjacent fixing faces 31 and contact faces 32. The fixing faces 31 of the lifting appliance 3 abut against the upper end face of the ceiling 2, and the contact faces 32 of the lifting appliance 3 face the mounting hole 21 and abut against the side of the electrical equipment 1 when the electrical equipment 1 is assembled. The fixing member is penetrated through the mounting hole 21 of the mounting portion 11, the ceiling 2 and the fixing hole 311 of the fixing face 31, and connected to the fixing hole 311 formed by the fixing face 31.

[0066] In an illustrative embodiment, as Figure 2 and Figure 3 As shown, the lifting appliance 3 is configured as a block-shaped structure. In detail, the lifting appliance 3 includes but is not limited to a block-shaped structure configured as a cube (or a roughly cube with rounded corners), which has a top face, a bottom face and four side faces between the top face and the bottom face. Further, the bottom face of the lifting appliance 3 serves as the fixing face 31 of the lifting appliance 3, and when the lifting appliance 3 is assembled on the upper end face of the ceiling 2, the lifting appliance 3 is arranged on the bottom face of the lifting appliance 3 in the vertical direction (such as Figure 2In the projection of the x direction), the projection of the bottom surface of the hanger 3 should at least partially coincide with the projection of the mounting portion 11 of the electrical appliance 1, so that the mounting hole 21 on the mounting portion 11 coincides with the fixing hole 311 on the fixing surface 31. The portion where the mounting hole 21 and the fixing hole 311 coincide is suitable for assembling a fixing member (such as a screw or a bolt, etc.). The fixing member is connected into the fixing hole 311 formed by the hanger 3, and the head (such as a screw head) of the fixing member is pressed against the mounting portion 11, so that the mounting portion 11 is tightly attached to the lower end surface of the ceiling 2.

[0067] In an exemplary embodiment, as shown in Figure 1 The side surface (left end surface) of the cubic structure facing the mounting hole 21 is used as the contact surface 32 of the hanger 3. In detail, when the hanger 3 is assembled to the upper end surface of the ceiling 2, the contact surface 32 should be substantially flush with the edge of the mounting hole 21 formed by the ceiling 2, or slightly protrude from the mounting hole 21 (i.e. in the projection of the vertical direction, the projection of the side edge of the mounting hole 21 coincides with the projection of the contact surface 32). In this way, when the electrical appliance 1 is assembled, the contact surface 32 can be tightly attached to the side portion of the electrical appliance 1, so as to adjust and / or limit the relative position of the electrical appliance 1 and the mounting hole 21.

[0068] In such an embodiment, the mounting portion 11 of the electrical appliance 1 and the fixing surface 31 of the hanger 3 are respectively pressed against the lower end surface and the upper end surface of the ceiling 2. When the fixing member is assembled with the hanger 3, the fixing member is sequentially threaded from bottom to top into the mounting portion 11, the ceiling 2 and the fixing surface 31 (as shown in Figure 1 In this way, the fixing member only passes through the ceiling 2, but does not have an assembly relationship with the ceiling 2, and therefore the texture of the ceiling 2 does not need to be considered. The fixing portion is assembled with the fixing hole 311 formed by the hanger 3, and the mass of the electrical appliance 1 is borne by the cooperation of the hanger 3 and the fixing member, so as to stably fix the electrical appliance 1 to the ceiling 2; and the contact surface 32 is attached to the side portion of the electrical appliance 1, so as to limit the position of the electrical appliance 1 relative to the mounting hole 21, and / or adjust the position of the electrical appliance 1 (or a portion of the electrical appliance 1) relative to the mounting hole 21, so as to facilitate the assembly of the electrical appliance 1 (which will be described in detail in the embodiment of the air conditioning device below). It should be understood that the embodiments of the present application are not limited thereto.

[0069] For example, in other embodiments, the fixing member can be sequentially threaded through the ceiling 2, the mounting portion 11 and the fixing surface 31. In this way, the stacking manner of the ceiling 2, the mounting portion 11 and the fixing surface 31, and the assembly sequence of the fixing member do not affect the mounting function of the hoisting mechanism of the present application.

[0070] Figure 4 is Figure 2 a sectional view of the hanger.

[0071] In an illustrative embodiment, as shown in Figure 4 To achieve the weight reduction of the lifting appliance 3, the lifting appliance 3 of the block structure can be designed as hollow or partially hollow.

[0072] Based on the above embodiments, as shown in Figure 2 and Figure 4 The lifting appliance 3 provided by the utility model needs to have adjacent fixing faces 31 and contact faces 32. In the longitudinal view of the lifting appliance 3 of the cubic structure, the extension directions of the fixing faces 31 and the contact faces 32 are substantially orthogonal. That is to say, in the lifting appliance 3 of the block structure, the surface facing the fixing faces 31 and / or the contact faces 32 can be omitted. Therefore, the weight reduction design of the lifting appliance 3 can be further achieved on the basis that the lifting appliance 3 has the fixing faces 31 and the contact faces 32.

[0073] For example, in another illustrative embodiment, not shown in the drawings, the lifting appliance 3 is configured as a plate structure with a bent middle part.

[0074] In an illustrative embodiment, not shown in the drawings, the lifting appliance 3 can be configured as a plate structure similar to an angle iron shape, that is, in the cross section along the width direction of the lifting appliance 3, the lifting appliance 3 can form a substantially L-shaped cross section. Further, the part of the plate structure forming the fixing hole 311 should have a certain thickness, so that this part can meet the structural requirements (such as the depth of the fixing hole 311, the structural strength, etc.) of the formed fixing hole 311. In this way, it is beneficial to achieve the weight reduction design of the lifting appliance 3. It should be understood that the embodiments of the utility model are not limited thereto.

[0075] For example, the lifting appliance 3 can also be configured as a "concave" structure with a through slot formed in the upper part.

[0076] Or, for example, the lifting appliance 3 can also be configured as a hollow square tube structure.

[0077] In addition, the lifting appliance 3 can also be configured as other polyhedral structures having the fixing faces 31 and the contact faces 32.

[0078] According to the embodiments of the utility model, as shown in Figure 4 The lifting appliance 3 is also provided with a cylindrical part. The cylindrical part is formed in the fixing face 31, and the fixing hole 311 extends from the fixing face 31 into the cylindrical part.

[0079] According to the embodiments of the utility model, as shown in Figure 4 The height (as shown in Figure 4 X3) of the cylindrical part is configured to be greater than 2 times the diameter (as shown in Figure 4 X4) of the fixing hole 311.

[0080] For the block structure, the square tube structure, the plate structure of the lifting appliance 3, based on the hollow or partially hollow design, in order to realize the assembly with the fixing part, the corresponding cylindrical part needs to be configured in the inside. Further, through the parameter design of the cylindrical part, it is beneficial to maintain the structural strength between the lifting appliance 3 and the fixing part (such as a screw). It should be understood that the embodiments of the present application are not limited to this.

[0081] For example, the ratio of the height of the cylindrical part to the diameter of the fixing hole 311 can also be configured as 1:1, 3:1, 4:1 and other arbitrary sizes, and the specific size should be appropriate to meet the assembly requirements of the fixing part.

[0082] Second embodiment

[0083] The second embodiment of the present application will be described below. The second embodiment has similar structures to the first embodiment, and the effects produced based on the structures will not be described here. For the convenience of describing the second embodiment and the following description, the lifting appliance 3 configured as a cubic structure will be described illustratively, unless otherwise stated. However, the lifting appliance 3 in the second embodiment and the following embodiments can also adopt the plate structure as in the first embodiment, or adopt a hollow or partially hollow design.

[0084] According to the embodiments of the present application, the lifting appliance 3 has a first end 33 and a second end 34 away from each other, and a fixing surface 31 and a contact surface 32 are defined between the first end 33 and the second end 34. The fixing surface 31 has a first edge 37 engaged with the contact surface 32, and a second edge 38 away from the contact surface 32.

[0085] According to the embodiments of the present application, the lifting appliance 3 is provided with a limiting part 35. The limiting part 35 is protruded from the contact surface 32.

[0086] In an illustrative embodiment, the two ends of the lifting appliance 3 configured as a substantially cubic structure are used as the first end 33 and the second end 34. In detail, the limiting part 35 is provided at the first end 33 (or a portion close to the first end 33) of the lifting appliance 3 and protrudes from the contact surface 32. That is, in the orthographic projection along the longitudinal direction of the lifting appliance 3, the projection of the limiting part 35 is exposed outside the projection of the lifting appliance 3.

[0087] In an illustrative embodiment, the limiting part 35 includes but is not limited to a sheet-like, block-like or other structure. Further, the limiting part 35 includes but is not limited to being formed integrally with the lifting appliance 3, or can be assembled with the lifting appliance 3 by bolting, riveting, welding or any other form. It should be understood that the embodiments of the present application are not limited to this.

[0088] For example, in addition to being provided at the first end 33, the limiting part 35 can also be provided at a portion of the contact surface 32 close to the first end 33.

[0089] In such an embodiment, when the installer (or user) installs the electrical equipment 1 through the hoisting mechanism, the hoist 3 is first placed above the ceiling 2 from the installation hole 21, and then the electrical equipment 1 is placed above the ceiling 2.

[0090] At this time, the relative position of the installation part 11 of the electrical equipment 1 and the fixing surface 31 of the hoist 3 needs to be adjusted, especially the positions of the installation hole 21 on the installation part 11 and the fixing hole 311 on the fixing surface 31 need to be adjusted to ensure that the positions correspond in the vertical direction. However, since the fixing surface 31 of the hoist 3 is blocked by the ceiling 2, the installer (or user) cannot observe the position of the fixing hole 311, and it is difficult to adjust the electrical equipment 1 to the appropriate position for fixing (i.e. assembling the fixing part). On this basis, the limiting part 35 can be used by the installer (or user) for blind installation (i.e. installation without visualizing the state of the hoist 3).

[0091] Specifically, when the installer (or user) performs blind installation, the installer can hold the hoist 3 on the ceiling 2 with one hand, and hold the electrical equipment 1 (or a part of the electrical equipment 1, which will be described in detail in the embodiment of the air conditioning device below) with the other hand. When adjusting the relative position of the hoist 3 and the electrical equipment 1, the installer (or user) can make the contact surface 32 of the hoist 3 closely adhere to the engagement position of the electrical equipment 1, and adjust the relative position of the hoist 3 and the electrical equipment 1 along the longitudinal direction of the hoist 3 (i.e. from the first end 33 to the second end 34, or from the second end 34 to the first end 33), until the limiting part 35 abuts against the electrical equipment 1. It can be considered that the hoist 3 and the electrical equipment 1 are assembled in place, i.e. the installation hole 21 and the fixing hole 311 correspond in the vertical direction. Thus, the blind installation operation of the installer (or user) can be realized.

[0092] It should be noted that in the above-mentioned second embodiment, the distance between the fixing hole 311 and the first end 33 (which can be considered as the limiting part 35), and the distance between the installation hole 21 and the side of the electrical equipment 1 should be configured to be substantially the same. It should be understood that the embodiments of the present application are not limited thereto.

[0093] For example, in some other embodiments, when there is no pre-set installation hole 21 and / or fixing hole 311 on the installation part 11 of the electrical equipment 1, the limiting part 35 is then used to assist the installer (or user) to estimate the relative position of the fixing hole 311 of the hoist 3 and the installation part 11 exposed below the ceiling 2, so that the installer (or user) can screw the fixing part (such as a quick screw) onto the fixing surface 31 of the hoist 3 without visualizing.

[0094] Third embodiment

[0095] The third embodiment of the utility model is described below. The third embodiment has similar structures to the first embodiment and / or the second embodiment, and the effects produced based on the structures are not described again here.

[0096] According to the embodiment of the utility model, as shown in Figure 2 The hoist 3 is also provided with a positioning portion 36. The positioning portion 36 is arranged on the contact surface 32 and protrudes from the contact surface 32. The electrical equipment 1 has a positioning hole 131 suitable for assembling with the positioning portion 36.

[0097] According to the embodiment of the utility model, as shown in Figure 2 The positioning portion 36 includes a first protrusion 361. In the projection of the first protrusion 361 along the vertical direction, the projection of the first protrusion 361 has a first distance (X1 as shown in Figure 2 The projection of the fixing hole 311 has a second distance (X2 as shown in Figure 2 from the first end 33. In detail, the second distance can be configured to be less than or equal to one half of the first distance.

[0098] In an illustrative embodiment, the contact surface 32 of the hoist 3 is provided with at least one positioning portion 36. In detail, the positioning portion 36 includes but is not limited to a first protrusion 361 configured to protrude outwardly from the contact surface 32. Further, the surface of the electrical equipment 1 facing the contact surface 32 is correspondingly provided with a positioning hole 131 suitable for being fitted with the positioning portion 36 (i.e. the first protrusion 361).

[0099] In an illustrative embodiment, the first protrusion 361 includes but is not limited to a structure configured as a substantially cylindrical structure, which can be a circular cylinder, an elliptical cylinder, a polygonal cylinder, or any other cylindrical structure. Further, the positioning hole 131 formed on the electrical equipment 1 should be configured to have a shape substantially the same as the cross section of the above-mentioned cylindrical structure, so as to be assembled with the first protrusion 361.

[0100] In such an embodiment, when the installer (or user) installs the electrical equipment 1 through the hoisting mechanism, the hoist 3 needs to be placed above the ceiling 2 from the mounting hole 21, and then the electrical equipment 1 is placed above the ceiling 2.

[0101] At this time, the relative position of the mounting portion 11 of the electrical equipment 1 and the fixing surface 31 of the lifting appliance 3 needs to be adjusted, especially the positions of the mounting hole 21 on the mounting portion 11 and the fixing hole 311 on the fixing surface 31 need to be adjusted to ensure that the positions in the vertical direction correspond. However, the fixing surface 31 of the lifting appliance 3 is blocked by the ceiling 2, so the position of the fixing hole 311 cannot be observed by the installer or the user, and it is difficult to adjust the electrical equipment 1 to a suitable position for fixing (i.e., assembling the fixing member). Since the positioning portion 36 is arranged on the contact surface 32, the installer (or the user) can see or touch (e.g., touch) the positioning portion 36 through the mounting hole 21 arranged on the ceiling 2. Therefore, the installer (or the user) can adjust the relative positions of the electrical equipment 1 and the lifting appliance 3 according to the assembly state of the positioning hole 131 and the positioning portion 36 when installing the electrical equipment 1.

[0102] When the positioning hole 131 of the electrical equipment 1 is not engaged with the positioning portion 36, the positioning portion 36 protruding from the contact surface 32 interferes with the side wall of the electrical equipment 1, that is, the electrical equipment 1 cannot be closely attached to the contact surface 32. At this time, the installer (or the user) can observe or touch the position of the positioning portion 36, and adjust the relative positions of the electrical equipment 1 and the lifting appliance 3 accordingly until the positioning hole 131 of the electrical equipment 1 is engaged with the positioning portion 36 of the lifting appliance 3. Therefore, it can be considered that the lifting appliance 3 and the electrical equipment 1 are assembled in place, that is, the positions of the mounting hole 21 and the fixing hole 311 in the vertical direction correspond, and the installer (or the user) can perform blind assembly.

[0103] Further, when the positioning hole 131 of the electrical equipment 1 is engaged with the positioning portion 36 (the positioning portion 36 can be regarded as a fulcrum), the electrical equipment 1 can be regarded as a lever. For example, the distance between the positioning portion 36 and the first end 33 is less than half of the distance between the fixing hole and the first end 33 (and the limiting portion), which may, during installation, cause the lifting appliance 3 to deviate relative to the electrical equipment 1 (e.g., the second end 34 of the lifting appliance 3 tilts towards the second side 38). Therefore, by setting the distance between the positioning portion 36 and the first end 33 to be greater than or equal to half of the distance between the fixing hole 311 and the first end 33, the lifting appliance 3 can be adjusted to a position where the fixing hole 311 and the mounting hole 21 are aligned, so that the electrical equipment (e.g., a connector) can be subsequently fixed to the ceiling.

[0104] According to an embodiment of the present application, the positioning portion 36 further comprises a second protrusion 362. The second protrusion 362 is arranged in a spaced manner with the first protrusion 361.

[0105] According to an embodiment of the present application, the second protrusion 362 is located between the first protrusion 361 and the first end 33.

[0106] Based on the deficiency of the above-mentioned embodiment in which the positioning portion 36 has only one first protrusion 361, the positioning portion 36 can also be configured with a second protrusion 362.

[0107] In an exemplary embodiment, the second protrusion 362 can be configured as a column structure similar to the first protrusion 361. Further, the second protrusion 362 can be arranged at a position on the line between the first protrusion 361 and the first end 33.

[0108] In such an embodiment, when the electric appliance 1 is assembled on the lifting appliance 3, the positioning portion 36 has two protrusions (i.e., the first protrusion 361 and the second protrusion 362). Since two points can determine a straight line, therefore, compared with the above-mentioned embodiment in which only the first protrusion 361 is arranged, the generation of the deviation problem can be effectively prevented. It should be understood that the embodiments of the present application are not limited thereto.

[0109] For example, a plurality of second protrusions 362 can also be arranged on the contact surface 32, and of course the side portion of the electric appliance 1 should also be provided with positioning holes 131 corresponding to the number and position of the second protrusions 362.

[0110] As described with reference to the second and third embodiments, the positioning portion 36 and the limiting portion 35 have similar functions, i.e., can be suitable for solving the problem that the installer (or user) assembles the electric appliance 1 on the lifting appliance 3 blindly. Therefore, based on this problem, the limiting portion 35 and the positioning portion 36 can be selectively arranged on the lifting appliance 3.

[0111] However, the above-mentioned positioning portion 36 and limiting portion 35 also have differences in function. For example, the limiting portion 35 is suitable for limiting the relative position of the lifting appliance 3 and the electric appliance 1 along the length direction of the lifting appliance 3, while the positioning portion 36 can limit the relative position of the lifting appliance 3 and the electric appliance 1 along the height direction of the lifting appliance 3. Therefore, the positioning portion 36 and the limiting portion 35 can also be arranged on the lifting appliance 3 at the same time, and specifically should be appropriate to meet the assembly requirements of the electric appliance 1.

[0112] Fourth Embodiment

[0113] The fourth embodiment of the present application will be described below, which has similar structures to the first embodiment and / or the second embodiment and / or the third embodiment, and the effects generated based on the structures will not be described herein.

[0114] According to the embodiments of the present application, as shown in Figure 4 The lifting appliance 3 also has a guide portion (which can be regarded as the contact surface 32 as shown in Figure 4 The upper portion of the guide portion is configured to extend to the mounting hole 21, and in the projection in the vertical direction, the projection of the guide portion protrudes from the first edge 37.

[0115] The upper portion of the guide portion is configured to extend toward the mounting hole 21, and the lower portion of the guide portion is configured to be substantially flush with the edge of the mounting hole 21. In a projection in the vertical direction, a projection of the guide portion protrudes from the first edge 37.

[0116] According to the embodiment of the present application, the surface of the guide portion facing the mounting hole 21 serves as the contact surface 32.

[0117] According to the embodiment of the present application, the contact surface 32 is an inclined surface inclined to the vertical direction.

[0118] In an exemplary embodiment, as shown in Figure 4 the upper portion of the guide portion extends toward the mounting hole 21, and the lower portion of the guide portion is substantially flush with the edge of the mounting hole 21. That is, when the lifting tool 3 is installed on the ceiling 2, the upper portion of the guide portion protrudes more than the lower portion toward the mounting hole 21. Further, the inclined direction of the guide portion can be configured to be continuous and gradual, so that the contact surface 32 forms a continuous inclined surface. It should be understood that the embodiments of the present application are not limited thereto.

[0119] For example, the upper portion and the lower portion of the guide portion can be spaced apart, and the upper portion of the guide portion forms a protruding portion.

[0120] Further, a plurality of protruding portions can be formed between the upper portion and the lower portion of the guide portion, and the size of the plurality of protruding portions protruding from the edge of the mounting hole 21 should be configured to gradually increase from the lower portion to the upper portion, so that the positions of the protruding portions abutting against the electrical appliance 1 form non-continuous contact surfaces 32.

[0121] In such an embodiment, the guide portion provided by the lifting tool 3 is suitable for application in the installation scenario of the electrical appliance 1 having at least two components.

[0122] For example, the electrical appliance 1 has a basket 12 (i.e., a first component) and a connector 13 (i.e., a second component) which are independent of each other. The connector 13 is configured as a plate-shaped structure, the lower portion of which is suitable for abutting against the contact surface 32 of the lifting tool 3, and the upper portion of which is suitable for being assembled with the basket 12 (the specific structures of the basket 12 and the connector 13 will be described in detail in the embodiments of the air conditioning device below).

[0123] Based on the above-mentioned electrical appliance 1 having the basket 12 and the connector 13, when installing, the installer (or user) can first install the connector 13 with the lifting tool 3. The connector 13 is configured as a plate-shaped structure and is provided with a mounting portion 11 (the specific structure of the mounting portion 11 is similar to that of the first embodiment, the second embodiment and the third embodiment described above, and will not be described here).

[0124] After the installation personnel (or user) assembles the mounting portion 11 of the connector 13 with the hanger 3 through the fixing member, the guide portion of the hanger 3 abuts against the connector 13. Since the contact surface 32 forms the guide portion inclined to the vertical direction and the upper portion is more protruded from the mounting hole 21 than the lower portion, the connector 13 abutting against the contact surface 32 also forms the trend of the upper portion inclined to the mounting hole 21. When further assembling the basket 12 with the connector 13, the installation personnel (or user) only needs to push the basket 12 upward in the state of abutting the lower portion of the connector 13 (the surface of the connector 13 away from the guide portion), so as to realize the assembly of the basket 12 and the connector 13, thereby facilitating the installation of the electrical equipment 1. The assembly mode of the basket 12 and the connector 13 includes but is not limited to the clamping mode, for example, one of the basket 12 and the connector 13 is provided with a clamping block, and the other of the basket 12 and the connector 13 is provided with a clamping head suitable for clamping with the clamping block.

[0125] Fifth embodiment

[0126] The fifth embodiment of the utility model is described below. The fifth embodiment has similar structures to the first embodiment and / or the second embodiment and / or the third embodiment and / or the fourth embodiment, and the effects generated based on the structures will not be described again here.

[0127] According to the embodiments of the utility model, as shown in Figure 3 and Figure 4 , the hanger 3 includes but is not limited to a block-shaped structure. Specifically, it can be configured as a block-shaped structure of a substantially cubic body as in the first embodiment or the second embodiment. The hanger 3 configured as a block-shaped structure is also provided with an error prevention portion 39, which is protruded from the surface away from the fixing surface 31 and / or the contact surface 32.

[0128] According to the embodiments of the utility model, as shown in Figure 3 and Figure 4 , the outer edge of the error prevention portion 39 is configured as an arc shape.

[0129] In an illustrative embodiment, as shown in Figure 3 and Figure 4 , the error prevention portion 39 includes but is not limited to a protruding rib.

[0130] The hanger 3 is provided with at least one protruding rib. In detail, the protruding rib is protruded from the surface of the hanger 3 away from the contact surface 32 and the surface away from the fixing surface 31. Further, the part of the protruding rib protruding from the two surfaces of the hanger 3 forms a continuous arc structure.

[0131] In another illustrative embodiment, as shown in Figure 3 and Figure 4As shown, the lifting tool 3 is provided with at least two protruding ribs. In detail, the two (or more) protruding ribs are arranged along the length direction of the lifting tool 3. At least one protruding rib is protruded by the surface away from the contact surface 32, and at least another protruding rib is protruded by the surface away from the fixing surface 31. It should be understood that the embodiments of the present application are not limited thereto.

[0132] For example, the outer edge of the protruding rib can also be configured as a triangle, a tooth shape, a polygon, or any other shape.

[0133] In such an embodiment, the anti-error part 39 (such as the protruding rib) protruded outwardly by the surface other than the fixing surface 31 and the contact surface 32 of the lifting tool 3 is actually an anti-error design, which can also be called a fool-proof design. Since the lifting tool 3 is arranged above the ceiling 2, it is generally higher than the visual angle of the installer (or user) during installation, and thus it is difficult to be visually confirmed. Moreover, since the lifting tool 3 is configured as a substantially cuboid structure, it is also difficult for the installer (or user) to identify the difference between the fixing surface 31 and the contact surface 32 and other surfaces by touch. Therefore, there is a possibility that the installation direction of the lifting tool 3 is reversed, which further leads to the misinstallation of the electrical appliance 1. The anti-error part 39 (such as the protruding rib) protruded outwardly by the surface other than the fixing surface 31 and the contact surface 32 of the lifting tool 3, on the one hand, forms a difference in shape, which is conducive to the installer (or user) confirming the correct installation direction by touch; on the other hand, since the outer edge of the anti-error part 39 is configured as an arc shape, even if the installer (or user) does not identify the correct installation direction, when the outer edge of the anti-error part 39 is configured to face the upper end surface of the ceiling 2 and / or the electrical appliance 1, it cannot form a stable abutting form with the ceiling 2 and the electrical appliance 1. Therefore, the anti-error part 39 can further play an anti-error role. Thus, the installer (or user) can confirm the installation direction of the lifting tool 3 without visual inspection, so as to facilitate installation and improve installation efficiency.

[0134] Figure 5 is a schematic view of an air conditioning device according to an exemplary embodiment of the present application. Figure 6 is Figure 5 is a use state diagram of a joint of the exemplary embodiment shown.

[0135] Based on an overall concept, as Figure 5 and Figure 6 shown, the present application also provides an air conditioning device, which comprises a hoisting mechanism and an electrical appliance 1, and the electrical appliance 1 is assembled to the contact surface 32 of the hoisting mechanism.

[0136] According to an embodiment of the present application, as Figure 5As shown, the electric appliance 1 comprises a housing 12 and a connector 13. The housing 12 has a vent 14. The connector 13 is assembled to the vent 14 to communicate the external air environment with the housing 12. Wherein, the connector 13 is mounted to the contact surface 32 of the hoisting mechanism.

[0137] In an exemplary embodiment, as shown in Figure 5 and Figure 6 the electric appliance 1 comprises a housing 12 and a connector 13. When the electric appliance 1 is installed to the ceiling 2, an installation hole 21 (such as a square hole) is needed to be opened on the ceiling 2 to assemble the connector 13 and the housing 12 to the ceiling 2 through the installation hole 21. In order to make the electric appliance 1 coordinate with the external environment and be more beautiful in visual effect, the installation hole 21 provided on the ceiling 2 should be as small as possible on the basis of meeting the installation conditions of the electric appliance 1. For this purpose, the housing 12 and the connector 13 of the electric appliance 1 can be configured as a split structure.

[0138] Based on the split structure, as shown in Figure 5 and Figure 6 when the electric appliance 1 is installed, the connector 13 can be assembled to the ceiling 2 through the installation hole 21 first, and then the housing 12 is assembled to the connector 13 through the installation hole 21. In this way, the size of the installation hole 21 only needs to meet the requirement of accommodating the housing 12 to pass through (the size of the connector 13 is smaller than that of the housing 12, so it can also pass through), so it can be set smaller.

[0139] In some exemplary embodiments, as shown in Figure 5 and Figure 6 the housing 12 forms the installation basis of the electric appliance 1. In detail, the housing 12 comprises but is not limited to a box-like structure, having opposite top and bottom surfaces and four side surfaces between the top and bottom surfaces. Further, the bottom surface and the side surfaces of the housing 12 are provided with openings, wherein the openings on the bottom surface face the installation hole 21 of the ceiling 2 and are used as air inlets; the openings on the side surfaces face the connector 13 and are used as air outlets. It should be noted that the housing 12 of the electric appliance 1 is also provided with a blower unit (such as a volute, a motor and a fan blade) and other functional units, which are not the focus of protection of the present utility model, and any functional unit that can be assembled in the housing 12 to enable the electric appliance 1 to exchange gas with the external air environment can be selected and applied. Therefore, it will not be described here.

[0140] For the electrical appliance 1 with the housing 12 and the joint 13, the installer (or user) can install the electrical appliance 1 on the ceiling 2 by any one of the hoisting mechanisms in the first embodiment, the second embodiment, the third embodiment, the fourth embodiment and the fifth embodiment to form an air conditioning device. The contact surface 32 of the hoist 3 is adapted to abut against the side surface of the joint 13 (e.g. the joint 13 plate) to fix the joint 13 on the ceiling 2 prior to the housing 12. Then, the housing 12 can be further pushed into the mounting hole 21 of the ceiling 2 and quickly assembled with the joint 13 according to the mounting method of the fourth embodiment. It should be understood that the embodiments of the present application are not limited thereto.

[0141] For example, in another illustrative embodiment, the electrical appliance 1 can be in one piece (i.e. can be considered as the joint 13 and the housing 12 integrally formed, or pre-assembled together before being placed above the ceiling 2).

[0142] For example, in another illustrative embodiment, the electrical appliance 1 can be in one piece (i.e. can be considered as the joint 13 and the housing 12 integrally formed, or pre-assembled together before being placed above the ceiling 2).
