Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a card connection structure, an air conditioner indoor unit and an air conditioner. Background Art

[0002] Snap-in connection structures are very common in component connections. For example, they are used to connect the middle frame and base of an air conditioner indoor unit. However, the disassembly method of this connection is relatively simple, such as disassembly by tools. These snap-in connection structures cannot choose different disassembly and assembly methods according to actual conditions, and cannot meet the humanized needs of modern industry. Summary of the invention

[0003] The problem solved by the present invention is how to solve the problem of a single disassembly method of a snap-on connection structure.

[0004] In order to solve the above-mentioned problem, on one hand, the present invention provides a snap-fit ​​connection structure, including a snap-fitting part, a first structure to be snap-fitted and a second structure to be snap-fitted; the first structure to be snap-fitted and the second structure to be snap-fitted are provided with through holes for at least one end of the snap-fitting part to pass through, and the snap-fitting part includes a snap-fitting part body and two clamping columns arranged on the snap-fitting part body; the snap-fitting part body can be rotatably inserted into the through holes, and the two clamping columns are suitable for respectively snapping with the first structure to be snap-fitted and the second structure to be snap-fitted, and the snap-fitting part also includes a tool coupling part and a hand-holding part which are also arranged on the snap-fitting part body.

[0005] Therefore, when disassembling and assembling the clamping part, the clamping part can be rotated by using a tool matching the tool coupling part, or force can be directly applied to the hand-held part to rotate the clamping part, or force can be applied to the hand-held part while using the tool. The clamping part can be disassembled and assembled in various forms, can meet various usage requirements, has high reliability and strong practicality.

[0006] Optionally, the through hole is used for all the clips to pass through.

[0007] Therefore, the positions of the tool coupling portion and the hand-held portion of the clamping member relative to the through hole can be replaced, the clamping member can be inserted into the through hole from the end where the first structure to be clamped or the second structure to be clamped is located, and the clamping member can be detached from the through hole from the end where the first structure to be clamped or the second structure to be clamped is located. The direction in which the clamping member detaches from the through hole can be the same as or opposite to the direction in which the clamping member is inserted into the through hole, thereby realizing reversible clamping, and the disassembly and assembly method of the clamping member can be flexibly changed to better meet usage requirements.

[0008] Optionally, the two clamping columns are respectively clamped with edges at two axial ends of the through hole.

[0009] Therefore, the structure of the snap-fit ​​connection structure is simpler, the processing cost is low, and the practicability is strong.

[0010] Optionally, the hand-held portion and the tool combining portion are respectively located at two ends of the axial direction of the connector body.

[0011] Thus, force can be applied to the clamping member from both axial ends of the through hole, thereby achieving detachment of the clamping member. The clamping member can be detached and assembled in various forms, with high reliability and strong practicality.

[0012] Optionally, the hand-held portion is a knob structure, and the knob structure is arranged to protrude from the axial end surface of the clamp body.

[0013] Therefore, the hand-held part is configured as a knob structure, and the rotating structure is configured to protrude from the axial end surface of the clamp body, which facilitates hand-held force application of the hand-held part, has a simple structure, and is highly practical.

[0014] Optionally, the tool engaging portion is a groove-shaped structure arranged at one axial end of the clamp body.

[0015] Therefore, the groove structure can be combined with some tools, so that force is applied to the clamping part through the tools, which facilitates the disassembly and assembly of the clamping part.

[0016] Optionally, the groove structure is a slot structure, a cross slot structure or a hexagonal slot structure.

[0017] Therefore, the snap-on connection structure can be assembled and disassembled using conventional tools, has a wide range of applications, and is highly practical.

[0018] Optionally, it also includes a plug-in connector and a bayonet structure, wherein the plug-in connector is provided on at least one of the clamping columns, and the bayonet structure is provided on the first structure to be clamped and / or the second structure to be clamped, or the bayonet structure is provided on at least one of the clamping columns, and the plug-in connector is provided on the first structure to be clamped and / or the second structure to be clamped; when the clamping connector is rotated until the clamping connector is respectively clamped with the first structure to be clamped and the second structure to be clamped, the plug-in connector is inserted into the bayonet structure and clamped with the bayonet structure.

[0019] Therefore, by providing the plug-in connector and the bayonet structure, the rotational position of the bayonet connector is locked by the bayonet connection between the plug-in connector and the bayonet structure, thereby preventing the bayonet connector from loosening due to vibration. The bayonet connection structure has high stability and strong practicality.

[0020] Optionally, a limiting rib structure is provided on the second structure to be clamped, and the limiting rib structure is located at one end of the second structure to be clamped away from the first structure to be clamped, and the limiting rib structure is used to contact the hand-held part to limit the displacement of the hand-held part along the axial movement of the through hole.

[0021] Thus, by setting the limiting rib structure, when the hand-held part is located near one end of the limiting rib structure, when the hand-held part contacts the limiting rib structure, the clamping part can be rotated to realize the clamping of the clamping part with the first structure to be clamped and the second structure to be clamped respectively. When the clamping part needs to be removed, the limiting rib structure presses the hand-held part to a certain extent, the resistance to disassembly of the clamping part is large, the limiting is reliable, and the stability is high. The clamping part can be removed with the help of a tool, which can be used in applications requiring high stability and high safety; when the tool combination part is located near one end of the limiting rib structure, the limiting rib structure does not contact the clamping part, the resistance to disassembly of the clamping part is relatively small, and the clamping part can be removed by applying force to the hand-held part. This state can be used in occasions without tools, or in occasions such as inspection, maintenance or testing that require repeated disassembly and assembly; the installation method of the clamping part can be selected according to actual usage requirements, which has high reliability and strong practicality.

[0022] Optionally, a limit stopper is further included, wherein the limit stopper is arranged on the first structure to be clamped and / or the second structure to be clamped, the limit stopper is located at the edge of the through hole, and the limit stopper is used to locate the rotation position of the clamping member.

[0023] Therefore, by setting the limit stopper, the rotation position of the clamping member is positioned to avoid the clamping member rotating to a position that is not in place or exceeds the clamping position, which affects the strength and stability of the clamping structure. The device has high reliability and strong practicality.

[0024] Optionally, one of the clamping columns is a second clamping column, the second clamping column and the tool engaging portion are located at the same axial end of the clamping component body, and the height of the limit stopper is greater than or equal to the height of the second clamping column.

[0025] Therefore, by setting the height of the limit stop to be greater than or equal to the height of the second clamping column, the second clamping column will not exceed the height of the limit stop, thereby avoiding the loosening of the clamping component due to rubbing against the second clamping column, and the safety and reliability are high; this situation can meet some special usage requirements, such as occasions with relatively high requirements for safety and stability.

[0026] Optionally, a guide surface structure is further included, which is arranged on the first structure to be clamped, the second structure to be clamped and at least one of the two clamping columns, and the guide surface structure is used to realize the movement guidance of the clamping part to rotate and clamp into the edge of the through hole.

[0027] Therefore, the guide surface structure is used to guide the movement of the clamping member to rotate and snap into the edge of the through hole, which facilitates the rotational snap-in and removal of the clamping member, has a simple structure and is highly practical.

[0028] On the other hand, the present invention also provides an air-conditioning indoor unit, including any one of the above-mentioned snap-in connection structures; and also including a middle frame and a base, the middle frame including a middle frame body, the base including a base body, the first structure to be snap-in of the snap-in connection structure is arranged on the middle frame body, and the second structure to be snap-in of the snap-in connection structure is arranged on the base body.

[0029] Therefore, when disassembling and assembling the clamping part, the clamping part can be rotated by using a tool matching the tool coupling part, or the hand-held part can be directly rotated, or the hand-held part can be rotated while using the tool. The clamping part can be disassembled and assembled in various forms, can meet various usage requirements, has high reliability and strong practicality.

[0030] Another aspect of the present invention provides an air conditioner, comprising any one of the above-mentioned snap-fit ​​connection structures and / or any one of the above-mentioned air conditioner indoor units. The beneficial effects of the air conditioner are the same as those of the snap-fit ​​connection structure and / or the air conditioner indoor unit, and will not be described in detail here.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0045] The drawings of this specification are provided with an XYZ coordinate system, wherein the positive direction of the X axis represents the right, the reverse direction of the X axis represents the left, the positive direction of the Y axis represents the front, the reverse direction of the Y axis represents the back, the positive direction of the Z axis represents the top, and the reverse direction of the Z axis represents the bottom, wherein "front", "back", "left", "right", "up" and "down" do not constitute limitations on specific structures, but are only based on the positions in the drawings. In this specification, unless otherwise clearly specified and limited, the up and down directions are consistent with the axial direction of the clamping member.

[0046] In addition, all directions or positional relationships mentioned in the embodiments of this specification are based on the positional relationships in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not imply or suggest that the referred device or element must have a specific orientation, and should not be understood as a limitation on the present invention.

[0047] like Figure 1 and Figure 5 As shown, an embodiment of the present invention provides a snap-on connection structure, comprising a snap-on component 1, a first structure to be snap-on 2 and a second structure to be snap-on 3; a through hole 21 for at least one end of the snap-on component 1 to pass through is provided on the first structure to be snap-on 2 and the second structure to be snap-on 3; the snap-on component 1 comprises a snap-on component body 11 and two clamping columns arranged on the snap-on component body 11; the snap-on component body 11 is rotatably inserted into the through hole 21, and the two clamping columns are suitable for respectively snapping with the first structure to be snap-on 2 and the second structure to be snap-on 3, and the snap-on component 1 also comprises a tool coupling portion 14 and a hand-holding portion 15 which are also arranged on the snap-on component body 11.

[0048] Exemplarily, the tool combining portion 14 is used to be combined with tools such as a flat-head screwdriver, a Phillips screwdriver, an external hexagonal wrench and a coin, and the hand-held portion 15 is used to apply force by hand, and force is applied to the clamping component 1 by means of tools and / or hand-held means, so as to realize the clamping connection of the clamping component 1 with the first structure to be clamped 2 and the second structure to be clamped 3, respectively, or to release the clamping state of the clamping component 1.

[0049] like Figure 1 and Figure 5As shown, exemplarily, the first structure to be clamped 2 and the second structure to be clamped 3 are provided with a clamping groove for clamping with the clamping column, and the clamping groove is opened on the side wall of the through hole 21. The clamping member 1 passes through the through hole 21, and the two clamping columns are respectively clamped with the second structure to be clamped 3 and the first structure to be clamped 2 by rotating.

[0050] In this description, the content of the present invention is described by taking the two clamping columns as the first clamping column 12 and the second clamping column 13, which are respectively clamped with the edges at both ends of the through hole 21 in the axial direction as an example. It should be understood that when the two clamping columns are respectively clamped with the edges at both ends of the through hole 21 in the axial direction, the structure of the clamping connection structure is simpler, the processing cost is low, and the practicality is strong.

[0051] It should be noted that the specific positions of the hand-held portion 15 and the tool coupling portion 14 are not limited as long as it is convenient to apply force. The hand-held portion 15 and the tool coupling portion 14 can be located at the same end or different ends of the clamping member 1. Exemplarily, the hand-held portion 15 and the tool coupling portion 14 are both located at the end where the first clamping column 12 / or the second clamping column 13 is located (not shown in the figure).

[0052] It should be noted that the clamp body 11 is rotatably inserted into the through hole 21 , and there is no restriction on the rotation angle of the clamp body 11 . Its rotation can realize the clamping with the first structure to be clamped 2 and the second structure to be clamped 3 respectively, which will not be described in detail here.

[0053] The advantage of such a configuration is that when disassembling and assembling the clamping component 1, the clamping component 1 can be rotated using a tool that matches the tool coupling portion 14, or force can be directly applied to the hand-held portion 15 to rotate the clamping component 1, or the hand-held portion 15 can be rotated while using a tool. The clamping component 1 can be disassembled and assembled in various forms, can meet a variety of usage requirements, has high reliability, and is strong in practicality.

[0054] like Figure 1 and Figure 5 As shown, the hand-held portion 15 and the tool-engaging portion 14 are respectively located at two ends of the axial direction of the clamp body 11. For example, the hand-held portion 15 and the tool-engaging portion 14 are respectively located at two ends of the axial direction of the through hole 21.

[0055] The advantage of this arrangement is that force can be applied to the clamping component 1 from both axial ends of the through hole 21, thereby achieving axial force application from both ends of the through hole 21 to disassemble and assemble the clamping component 1. The clamping component 1 can be disassembled and assembled in various forms, with high reliability and strong practicality.

[0056] In this specification, the present invention is described by taking the example that the hand-held portion 15 and the first clamping column 12 are located at one axial end of the through hole 21 , and the tool coupling portion 14 and the second clamping column 13 are located at the other axial end of the through hole 21 .

[0057] like Figure 5 and Figure 6 As shown, in one embodiment, the through hole 21 includes a through hole body 211 and a through groove 212 arranged on the side wall of the through hole body 211, the clamping member body 11 is rotatably penetrated in the through hole body 211, and the through groove 212 is used for the passage of the end where the first clamping column 12 is located on the clamping member 1. At this time, the first clamping column 12 and the hand-held part 15 can pass through the through groove 212; after the end where the first clamping column 12 on the clamping member 1 passes through the through hole 21, the clamping member 1 is rotated so that the first clamping column 12 and the second clamping column 13 are respectively clamped with the edges at the axial ends of the through hole body 211, so that the clamping member 1 is respectively clamped with the second structure to be clamped 3 and the first structure to be clamped 2. Here, the cross-sectional shape of the connector body 11 can be rectangular, elliptical, etc., which is not a limitation, as long as the connector body 11 can pass through the through-hole body 211 and rotate in the through-hole body 211. Of course, the cross-sectional shape of the connector body 11 is preferably circular, and the through-hole body 211 can match the connector body 11.

[0058] like Figure 5 and Figure 6 As shown, it should be noted that the through hole 21 is composed of through hole structures respectively arranged on the first structure to be clamped 2 and the second structure to be clamped 3, that is, the through hole body 211 and the through slot 212 are both assembled structures. For example, the through hole body 211 includes a first through hole body 2111 and a second through hole body 2112, and the first through hole body 2111 and the second through hole body 2112 are respectively arranged on the first structure to be clamped 2 and the second structure to be clamped 3; the through slot 212 includes a first through slot 2121 and a second through slot 2122, and the first through slot 2121 and the second through slot 2122 are respectively arranged on the first structure to be clamped 2 and the second structure to be clamped 3; accordingly, the first through slot 2121 is arranged on the side wall of the first through hole body 2111, and the second through slot 2122 is arranged on the side wall of the second through hole body 2112. It should be noted that the cross-sectional shapes of the first through hole body 2111 and the second through hole body 2112 do not have to be exactly the same, and the cross-sectional shapes of the first through groove 2121 and the second through groove 2122 do not have to be exactly the same. The combined through hole structure only needs to be able to allow at least one end of the clip 1 to pass through, which will not be described in detail here.

[0059] In an embodiment of the present invention, Figure 1 and Figure 3 As shown, the hand-held portion 15 is a knob structure, and the knob structure is arranged to protrude from the axial end surface of the clamp body 11. For example, the knob structure is a rectangular plate or a semicircular plate.

[0060] It should be noted that when one end of the hand-held portion 15 needs to pass through the through hole 21, the cross-sectional area of ​​the hand-held portion 15 should be smaller than the cross-sectional area of ​​the through hole 21; Figure 1 and Figure 3 As shown, in one embodiment, the superposition of the orthographic projections of the connector body 11 and the first connector column 12 on the cross section of the connector 1 completely covers the orthographic projection of the hand-held portion 15 on the cross section of the connector 1, and the hand-held portion 15 is integrally connected to the first connector column 12. In this way, the hand-held portion 15 has a simple structure, high force stability, and strong practicality.

[0061] The advantage of such a configuration is that the hand-held portion 15 is configured as a knob structure, and the rotating structure is configured to protrude from the axial end surface of the clamp body 11 , which facilitates the hand-held force application of the hand-held portion 15 , has a simple structure, and is highly practical.

[0062] In an embodiment of the present invention, the tool engaging portion 14 is a groove-shaped structure provided at one axial end of the clamp body 11. For example, the groove-shaped structure may be recessed in the clamp body 11, or a boss may be provided at the end of the clamp body 11, and the groove-shaped structure is provided on the boss.

[0063] The advantage of such a configuration is that the groove structure can be combined with some tools, so that force can be applied to the clamping member 1 through the tools, thereby facilitating the assembly and disassembly of the clamping member 1.

[0064] In an embodiment of the present invention, Figure 1 and Figure 3 As shown, the slot structure is a slot structure, a cross slot structure or a hexagonal slot structure. The widths of the two slots of the cross slot structure can be different, and can be combined with a coin and / or a cross screwdriver.

[0065] The advantage of such a configuration is that the clamping member 1 can be assembled and disassembled using relatively conventional tools, and has a wide range of applications and strong practicality.

[0066] like Figure 1 and Figure 3 As shown, in the embodiment of the present invention, the through hole 21 is used for the entire passage of the clamping member 1 .

[0067] That is to say, by inserting either end of the clamping member 1 into the through hole 21 and rotating the clamping member 1, the clamping member 1 can be respectively clamped with the first structure to be clamped 2 and the second structure to be clamped 3 (for example, the first clamping column 12 and the second clamping column 13 are respectively clamped with the edges at the axial ends of the through hole 21); when the clamping member 1 needs to be removed, the clamping member 1 is rotated in the opposite direction, and then force is applied through the tool coupling portion 14 and / or the hand-held portion 15 to make the clamping member 1 move toward either axial end of the through hole 21 to remove the clamping member 1.

[0068] The advantage of such a configuration is that the positions of the tool coupling portion 14 and the hand-held portion 15 of the clamping component 1 relative to the through hole 21 can be replaced, the clamping component 1 can be inserted into the through hole 21 from the end where the first structure to be clamped 2 or the second structure to be clamped 3 is located, and the clamping component 1 can be detached from the through hole 21 from the end where the first structure to be clamped 2 or the second structure to be clamped 3 is located, and the direction in which the clamping component 1 is detached from the through hole 21 can be the same as or opposite to the direction in which the clamping component 1 is inserted into the through hole 21, thereby realizing reversing clamping, and the disassembly and assembly method of the clamping component 1 can be flexibly changed to better meet usage requirements.

[0069] like Figure 1 and Figure 3 As shown, in an embodiment of the present invention, the first clamping column 12 and the second clamping column 13 may be the same or different. Exemplarily, the first clamping column 12 and the second clamping column 13 are respectively located at two ends of the axial direction of the clamp body 11, and the outer contour of the projection of the first clamping column 12 on the cross section of the clamp body 11 is the same as the outer contour of the projection of the second clamping column 13 on the cross section of the clamp body 11.

[0070] In one embodiment, the projection of the first clamping column 12 on the cross section of the clamping body 11 coincides with the projection of the second clamping column 13 on the cross section of the clamping body 11. At this time, the cross-sectional shape of the through groove 212 can be the same as the cross-sectional shape of the second clamping column 13, that is, the cross-sectional shapes of the first through groove 2121 and the second through groove 2122 are the same as the cross-sectional shape of the second clamping column 13. In this way, the through hole 21 of the first structure 2 to be clamped and the second structure 3 to be clamped has a simple structure, convenient processing, and strong practicality. The cross section here is the XY plane in the accompanying drawings.

[0071] The advantage of such a configuration is that both the first clamping column 12 and the second clamping column 13 can pass through the through hole 21, and the clamping component 1 can be inserted into the through hole 21 at either axial end of the through hole 21, and can also be detached from the through hole 21 at either axial end of the through hole 21, so that the disassembly and assembly methods of the clamping component 1 can be flexibly changed, and the structure of the clamping component 1 is simple, compact, and highly practical.

[0072] like Figure 1 and Figure 8 As shown, in an embodiment of the present invention, it also includes a guide surface structure 3112, and the guide surface structure 3112 is arranged on at least one of the first clamping column 12, the second clamping column 13, the first structure to be clamped 2 and the second structure to be clamped 3, and the guide surface structure 3112 is used to realize the movement guidance of the clamping component 1 to rotate and clamp into the edge of the through hole 21.

[0073] like Figure 8 and Fig. 9 As shown, taking the guide surface structure 3112 being provided on the second structure to be clamped 3 as an example, the guide surface structure 3112 is located at the edge of the second through hole body 2112 on the second structure to be clamped 3, and the second structure to be clamped 3 is located in the screw-in direction of the clamping member 1. Here, the screw-in direction refers to the rotation direction of the clamping member 1 so that the clamping member 1 is clamped with the axial edge of the through hole 21. For example, Figure 8 As shown, the guide surface structure 3112 may be a guide slope and / or a guide arc surface disposed at the opening of the second through slot 2122. The guide surface structure 3112 is connected to the side wall of the second through slot 2122.

[0074] The advantage of such a configuration is that the guide surface structure 3112 can be used to guide the movement of the clamping member 1 to rotate and snap into the edge of the through hole 21, thereby facilitating the rotational snap-in and removal of the clamping member 1 , and the structure is simple and practical.

[0075] In an embodiment of the present invention, Figure 1 , Figure 2 and Figure 6 As shown, the clamping connection structure further includes a limit stopper 22, which is disposed on the first structure to be clamped 2, and is located at the edge of the through hole 21, and is used to position the rotation position of the clamping member 1.

[0076] For example, Figure 6As shown, the limit stop block 22 is arranged on the edge of the first through hole body 2111 on the first structure to be clamped 2 away from one end of the second through hole body 2112, and the limit stop block 22 is located in the screw-in direction of the clamping member 1. When the clamping member 1 is rotated until the limit stop block 22 is in contact with the first clamping column 12 or the second clamping column 13, the clamping member 1 is rotated into place, and the clamping member 1 is in a state of being respectively clamped with the first structure to be clamped 2 and the second structure to be clamped 3.

[0077] like Figure 6 As shown, in one embodiment, a receiving groove 23 is provided on the first structure to be clamped 2, and the receiving groove 23 is used to receive the first clamping column 12 or the second clamping column 13, and the limit stopper 22 is provided on the bottom wall of the receiving groove 23. Figure 1 and Figure 2 As shown, in another embodiment, the limit stopper 22 is a retaining rib arranged on the first structure to be clamped 2. Of course, the limit stopper 22 can also be arranged on the second structure to be clamped 3, which will not be described in detail here.

[0078] The advantage of such a setting is that by setting the limit stop block 22, the rotation position of the clamping member 1 can be positioned to prevent the clamping member 1 from rotating out of position or exceeding the clamping position, which would affect the strength and stability of the clamping structure. It has high reliability and strong practicality.

[0079] like Figure 1 , Figure 2 and Figure 6 As shown, in an embodiment of the present invention, the second clamping column 13 and the tool engaging portion 14 are located at the same axial end of the clamping component body 11 , and the height of the limit stopper 22 is greater than or equal to the height of the second clamping column 13 .

[0080] like Figure 1 , Figure 2 and Figure 6 As shown, it should be noted that the height direction of the limit stopper 22 is consistent with the axial direction of the through hole 21, and the height direction of the second clamping column 13 is consistent with the axial direction of the clamping component body 11. Figure 6 At this time, along the axial direction of the through hole 21, the second clamping column 13 will not protrude from the limit stopper 22, and the end where the second clamping column 13 is located can only be disassembled and assembled using a tool that matches the tool coupling portion 14.

[0081] The advantage of such a setting is that, by setting the height of the limit stopper 22 to be greater than or equal to the height of the second clamping column 13, the second clamping column 13 will not exceed the height of the limit stopper 22, thereby preventing the clamping member 1 from loosening due to rubbing against the second clamping column 13, and having high safety and reliability. This situation can meet some special use requirements, such as occasions with relatively high requirements for safety and stability.

[0082] like Figure 3 , Figure 7 and Fig. 9 As shown, in an embodiment of the present invention, the snap-on connection structure also includes a plug-in connector 221 and a bayonet structure 101, the bayonet structure 101 is provided on the first clamping column 12 and / or the second clamping column 13, and the plug-in connector 221 is provided on the first structure to be clamped 2 and / or the second structure to be clamped 3; when the clamping component 1 is rotated until the clamping component 1 is respectively clamped with the first structure to be clamped 2 and the second structure to be clamped 3, the plug-in connector 221 is inserted into the bayonet structure 101 and clamped with the bayonet structure 101.

[0083] like Figure 7 and Fig. 9 As shown, in one embodiment, the connector 221 is arranged on the limit block 22, and the connector 221 is arranged as a hook structure. When the connector 1 rotates along the screw-in direction, the first clamping column 12 and the second clamping column 13 are respectively engaged with the edges at both axial ends of the through hole 21, and the hook structure is inserted into the bayonet structure 101 and engaged with the bayonet structure 101 to lock the rotational position of the connector 1; the connector 221 rotates in the opposite direction, and the hook structure is separated from the bayonet structure 101.

[0084] like Figure 3 As shown, it should be noted that when the bayonet structure 101 is provided on the first clamping column 12 and the second clamping column 13, and the plug-in component 221 is provided on the first structure to be clamped 2 and the second structure to be clamped 3; when the first clamping column 12 needs to be able to clamp with the first structure to be clamped 2 and needs to be able to change direction to clamp with the second structure to be clamped 3, the opening directions of the bayonet structure 101 on the first clamping column 12 and the second clamping column 13 should be opposite.

[0085] It should be noted that the connector 221 may also be disposed on the first clamping column 12 and / or the second clamping column 13, and correspondingly, the bayonet structure 101 may also be disposed on the first structure to be clamped 2 and / or the second structure to be clamped 3, which will not be described in detail here.

[0086] The advantage of such a configuration is that, by providing the plug-in connector 221 and the bayonet structure 101, the rotational position of the bayonet connector 1 is locked through the bayonet connection between the plug-in connector 221 and the bayonet structure 101, thereby preventing the bayonet connector 1 from loosening due to vibration, and the bayonet connection structure has high stability and strong practicality.

[0087] like Figure 2 and Figure 8 As shown, in an embodiment of the present invention, when the hand-held portion 15 and the tool coupling portion 14 are respectively located at two ends of the axial direction of the clamp body 11, a limiting rib structure 32 is provided on the second structure to be clamped 3, and the limiting rib structure 32 is located on the end of the second structure to be clamped 3 away from the first structure to be clamped 2, and the limiting rib structure 32 is used to contact the hand-held portion 15 to limit the displacement of the hand-held portion 15 along the axial movement of the through hole 21.

[0088] like Figure 2 and Figure 8 As shown, it should be noted that, in one embodiment, the second structure to be clamped 3 includes the second structure to be clamped body 31 and the limiting rib structure 32, and the limiting rib structure 32 is integrally connected to the second structure to be clamped body 31. When the hand-held portion 15 and the first clamping column 12 pass through the through hole 21 from the end where the first structure to be clamped 2 is located, and the hand-held portion 15 begins to contact the limiting rib structure 32, the clamping member 1 is rotated along the screw-in direction, and the first clamping column 12 and the hand-held portion 15 are gradually clamped between the edge of the through hole 21 and the limiting rib structure 32. As the clamping member 1 rotates, the first clamping column 12 and the hand-held portion 15 are respectively in contact with the edge of the through hole 21 and the limiting rib structure 32. The resistance to disassembly of the clamping member 1 is greater, the limiting is reliable, and the stability is high. The clamping part 1 can be disassembled with the help of tools. This state can be used in applications that require high stability and high safety. When the tool coupling part 14 and the second clamping column 13 pass through the through hole 21 from the end where the first structure to be clamped 2 is located, and the second clamping column 13 is clamped with the edge of the through hole 21, the limiting rib structure 32 does not contact the clamping part 1. At this time, the resistance to disassembly of the clamping part 1 is relatively small. The clamping part 1 can be disassembled by applying force to the hand-held part 15. This state can be used in occasions without tools, or in occasions that require repeated disassembly and assembly, such as inspection, maintenance or testing. Of course, the part of the limiting rib structure 32 that contacts the hand-held part 15 can be set as an elastic structure to enhance the resistance to disassembly and assembly of the clamping part 1, which will not be described in detail here.

[0089] The advantage of such a configuration is that, by setting the limiting rib structure 32, the limiting rib structure 32 is used to abut against the end of the hand-held portion 15 away from the tool coupling portion 14. When the hand-held portion 15 abuts against the limiting rib structure 32, the resistance to disassembly of the clip 1 is large, the limiting is reliable, and the stability is high. The clip 1 can be disassembled with the aid of a tool, and can be used in applications requiring high stability and high safety; when the tool coupling portion 14 is located at one end close to the limiting rib structure 32, the limiting rib structure 32 does not contact the clip 1, and the resistance to disassembly of the clip 1 is relatively small. The clip 1 can be disassembled by applying force to the hand-held portion 15. This state can be used in occasions without tools, or in occasions such as inspection, maintenance or testing that require repeated disassembly and assembly; the installation method of the clip 1 can be selected according to actual usage requirements, with high reliability and strong practicality.

[0090] like Figure 2 As shown, in another embodiment, the limiting rib structure 32 is detachably connected to the second structure body 31 to be clamped, for example, the limiting rib structure 32 is threadedly connected to the second structure body 31 to be clamped, the limiting rib structure 32 includes a base 321 and a limiting rib 322, the base 321 is threadedly connected to the second structure body 31 to be clamped, the limiting rib 322 is located on the base 321 at an end away from the first structure 2 to be clamped, and the limiting rib 322 is used to abut against the hand-held portion 15. In other embodiments, the base 321 can also be clamped with the second structure body 31 to be clamped, and the clamping direction of the base 321 and the second structure body 31 to be clamped can be perpendicular to the axial direction of the through hole 21.

[0091] The advantage of such a configuration is that when the limiting rib structure 32 abuts against the hand-held portion 15, when it is inconvenient to use the tool coupling portion 14 to disassemble the clip 1, the limiting rib structure 32 can be removed to expose the hand-held portion 15, and the clip 1 can be removed by applying force to the hand-held portion 15. This can not only meet the use requirements of different disassembly and assembly resistances of the clip 1, but also maintain a variety of disassembly and assembly methods, with high reliability and strong practicality.

[0092] like Figure 4 , Figure 5 and Figure 8 As shown, another embodiment of the present invention provides an air-conditioning indoor unit, including the snap-in connection structure described in any one of the above items; and also including a middle frame 4 and a base 5, the middle frame 4 includes a middle frame body 41, the base 5 includes a base body 51, the first structure to be snap-in 2 of the snap-in connection structure is arranged on the middle frame body 41, and the second structure to be snap-in 3 of the snap-in connection structure is arranged on the base body 51.

[0093] The advantage of such a configuration is that when disassembling and assembling the clamping component 1, the clamping component 1 can be rotated using a tool that matches the tool coupling portion 14, or the hand-held portion 15 can be directly rotated, or the hand-held portion 15 can be rotated while using the tool. The clamping component 1 can be disassembled and assembled in various forms, can meet various usage requirements, has high reliability, and is strong in practicality.

[0094] like Figure 8 As shown, in an embodiment of the present invention, the through hole 21 is used for the entire passage of the clamping member 1. When a limiting rib structure 32 is provided on the second structure to be clamped 3, the clamping member 1 can be used in various ways. For example, in one embodiment, during the debugging and assembly process in the factory, the hand-held portion 15 is located at the end where the middle frame 4 is located, which is convenient for repeated disassembly and assembly that may occur; when it is necessary to be transported out of the factory, the tool coupling portion 14 is located at the end where the middle frame 4 is located, so as to prevent the clamping member 1 from loosening during transportation and the air-conditioning indoor unit from falling apart. In one embodiment, according to whether the user has tools or the type of tools, or according to the user's needs, the user is provided with an air-conditioning indoor unit in which the hand-held portion 15 is located at the end where the middle frame 4 is located, or an air-conditioning indoor unit in which the tool coupling portion 14 is located at the end where the middle frame 4 is located.

[0095] Another embodiment of the present invention provides an air conditioner, the air conditioner comprising any one of the above-mentioned snap-in connection structures and / or any one of the above-mentioned air conditioner indoor units. The air conditioner has the beneficial effects of the snap-in connection structure, which will not be described in detail here.

[0096] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
