Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a buckle structure, a display box installation structure and an air conditioner. Background Art

[0002] In air conditioners, snap-fit ​​structures are widely used to install components. For example, a display box is installed on a panel of the air conditioner through the snap-fit ​​structure. Although the snap-fit ​​structure has a simple structure and is easy to assemble and disassemble, it is prone to deflection and disengagement and has low stability. Summary of the invention

[0003] The problem solved by the present invention is how to design a buckle structure to at least partially solve the problem that the buckle connection is prone to deflection and disengagement and has low stability.

[0004] To solve the above problems, the present invention provides a buckle structure on one hand, including a first buckle and a second buckle, the first buckle including a first buckle body and a limiting protrusion arranged on the first buckle body, the second buckle including a second buckle body, the second buckle body is provided with an opening, the first buckle body is passed through the opening, the limiting protrusion is engaged with the edge of the opening, the side wall of the opening is provided with a limiting groove, the first buckle also includes a limiting structure, and the limiting structure is limitedly matched with the limiting groove.

[0005] Therefore, a limiting groove is provided on the side wall of the opening, and the limiting protrusion passes through the opening and is engaged with the edge of the opening. At this time, the limiting structure and the limiting groove cooperate to achieve the limiting of the first buckle and the second buckle. The first buckle and the second buckle are engaged with each other with high stability, not prone to deflection, high reliability and strong practicality.

[0006] Optionally, the limiting structure is integrally connected to the first buckle body.

[0007] Therefore, by integrally connecting the limiting structure with the first buckle body, the structural rigidity of the first buckle body is enhanced, and the overall structure of the buckle structure is compact, occupies a small space, and is highly practical.

[0008] Optionally, the limiting groove includes a first accommodating groove, the limiting structure includes a limiting column, the limiting column is at least partially accommodated in the first accommodating groove, and the first accommodating groove is used to limit the displacement of the first buckle in the length direction of the limiting protrusion.

[0009] Therefore, the limiting structure includes a limiting column, which limits the displacement of the first buckle in the length direction of the limiting protrusion through the cooperation between the first accommodating groove and the limiting column, and limits the deflection of the first buckle. The first buckle and the second buckle have high stability and strong practicality.

[0010] Optionally, the limiting column is located below the limiting protrusion, and the limiting column and the limiting protrusion are located on the same side of the first buckle body.

[0011] Therefore, the limiting column is located below the limiting protrusion, and when the limiting protrusion passes through the opening, under the deformation of the first buckle body, the limiting protrusion and the limiting column move toward the direction close to the first accommodating groove, the limiting protrusion is engaged with the edge of the opening, the limiting column is partially accommodated in the first accommodating groove, the first buckle and the second buckle are stably connected, the first buckle has a compact structure, high reliability and strong practicality.

[0012] Optionally, the orthographic projection of the limiting protrusion on the cross section of the first buckle body completely covers the orthographic projection of the limiting column on the cross section of the first buckle body.

[0013] As a result, the width of the first accommodating groove can be smaller than the width of the opening, and the first accommodating groove only needs to be arranged on one side wall of the opening. When the first buckle body is deformed and the limiting protrusion is separated from the edge of the opening, the limiting column directly detaches from the first accommodating groove, and the limiting column does not form an obstacle to the movement of the first buckle body. At the same time, the limiting column does not exceed the edge of the limiting protrusion along the protruding direction, ensuring that the limiting protrusion and the edge of the opening have a sufficient clamping surface, ensuring the strength of the clamping connection between the limiting protrusion and the edge of the opening, and having high reliability and strong practicality.

[0014] Optionally, the first accommodating groove and the limiting column are interference fit.

[0015] Therefore, by setting an interference fit between the first accommodating groove and the limiting column, when the first accommodating groove and the limiting column are limitedly fitted, the first accommodating groove has a tendency to hold the limiting column tightly, which can prevent the limiting column and the first buckle body from deformation to a certain extent, thereby improving the connection stability of the buckle structure.

[0016] Optionally, a ratio of a length of the limiting column to a length of the first buckle body is between 1:1 and 1:5.

[0017] Therefore, by setting different ratios of the length of the limiting column to the length of the first buckle body, the first buckle body can obtain different degrees of elasticity or limiting force. For example, when the length of the limiting column is smaller than the length of the first buckle body, the first buckle body maintains good elasticity and is convenient for snapping. When the length of the limiting column is equal to the length of the first buckle body, the overall rigidity of the connection between the limiting protrusion and the first buckle body is enhanced and the stability is high. In addition, the length of the limiting column will not exceed the length of the first buckle body, thereby avoiding the buckle structure from occupying too much space.

[0018] Optionally, the cross-sectional shape of the limiting column includes any one of a sector shape, a semicircle shape, a rectangle shape and a trapezoid shape.

[0019] Therefore, the cross-sectional shape of the limiting column includes any one of a sector, a semicircle, a rectangle and a trapezoid, the first receiving groove has high limiting reliability for the limiting column, and when the cross-sectional shape of the limiting column includes a sector, a semicircle, a rectangle or a trapezoid, the limiting column has a certain sliding guide when entering the first receiving groove, and the structure is simple and the practicability is strong.

[0020] Optionally, the limiting structure includes a limiting seat, the limiting seat is connected to the first buckle body, the limiting groove includes a second accommodating groove, and the limiting seat is plugged and matched with the second accommodating groove along the direction in which the first buckle body is inserted into the opening.

[0021] The limiting seat and the second accommodating groove are thus provided, and the limiting seat is plugged into and cooperates with the second accommodating groove along the direction in which the first buckle body is inserted into the opening, so as to realize the limitation of the first buckle in any direction within the cross-section of the first buckle body, and the positioning between the first buckle and the second buckle is more reliable, and the first buckle and the second buckle are not prone to deflection, with high reliability and strong practicality.

[0022] Optionally, the limiting seat is a truncated cone structure or a prism structure, and the second accommodating groove matches the limiting seat.

[0023] Therefore, the limit seat is a truncated cone structure or a prism structure, and the inclined surface of the truncated cone structure or the prism structure can guide the insertion of the limit seat into the second accommodating groove, which is convenient for plugging in. Moreover, the inclined surface of the truncated cone structure or the prism structure limits the first buckle body to a certain extent from continuing to move in the direction in which the first buckle body is inserted into the opening, causing the limit protrusion to separate from the edge of the opening.

[0024] On the other hand, the present invention provides a display box installation structure, including any one of the above-mentioned snap-in structures, and also including a panel and a display box, the display box includes a display box body, and the panel includes a panel body; the first snap-in structure of the snap-in structure is arranged on the panel body, and the second snap-in structure of the snap-in structure is arranged on the display box body.

[0025] Therefore, the panel and the display box are connected via the buckle structure, which can not only realize the connection between the panel and the display box, but also limit the deflection of the display box to a certain extent, and is convenient for disassembly and assembly and has high reliability.

[0026] Optionally, the display box further comprises an inserting piece structure, the inserting piece structure is arranged at one end of the display box body, the panel body is provided with a slot structure, and the inserting piece structure is plugged and matched with the slot structure.

[0027] Therefore, the display box is positioned by the insertion cooperation between the inserting piece structure and the slot structure; and the display box and the panel are locked by the buckle structure, so that the assembly is quick and convenient, the number of screws used is reduced, the reliability is high, and the practicability is strong.

[0028] Optionally, the second buckle is arranged at the other end of the display box body, and the limiting protrusion of the first buckle is located on a side of the first buckle body of the first buckle away from the slot structure.

[0029] As a result, the display box is quick and easy to assemble, and the limiting protrusion of the first buckle is located on the side of the first buckle body away from the slot structure, so that when the panel is an arc-shaped structure protruding outward, the limiting protrusion and the opening will not be separated due to the inward pressing force on the panel, and the reliability is high and the practicality is strong.

[0030] Another aspect of the present invention provides an air conditioner, comprising any one of the above-mentioned buckle structures. The beneficial effects of the air conditioner are the same as those of the buckle structure, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] 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.

[0051] An embodiment of the present invention provides a buckle structure, including a first buckle 1 and a second buckle 2, wherein the first buckle 1 includes a first buckle body 11 and a limiting protrusion 12 arranged on the first buckle body 11, and the second buckle 2 includes a second buckle body 21, and an opening 211 is arranged on the second buckle body 21, the first buckle body 11 is passed through the opening 211, the limiting protrusion 12 is engaged with the edge of the opening 211, and the side wall of the opening 211 is provided with a limiting groove 212, and the first buckle 1 also includes a limiting structure 13, and the limiting structure 13 is limitedly matched with the limiting groove 212.

[0052] like Figure 1 and Figure 2 As shown, the first buckle body 11 is arranged along the Z-axis direction in the accompanying drawings, and the length direction of the first buckle body 11 is also the Z-axis direction in the accompanying drawings. The limiting protrusion 12 is protruded on the first buckle body 11 along a direction perpendicular to the length direction of the first buckle body 11, that is, the limiting protrusion 12 is protruded on the first buckle body 11 along the Y-axis direction in the accompanying drawings. In some embodiments, the first buckle body 11 can be set as a spring structure.

[0053] The limiting groove 212 is arranged along the length direction of the first buckle body 11, and the length direction of the limiting groove 212 is consistent with the depth direction of the opening 211, both of which are the Z-axis direction in the accompanying drawings. In some embodiments, the limiting groove 212 is arranged as an opening structure at one end close to the first buckle 1, that is, the limiting groove 212 penetrates the second buckle body 21 in the reverse direction along the Z-axis.

[0054] It should be noted that a guide surface structure 121 is provided at one end indicated by the protruding direction of the limiting protrusion 12, for example, the guide surface structure 121 is a guide slope or a guide arc surface; during the process of inserting the first buckle body 11 into the opening 211 in the positive direction along the Z axis, the limiting protrusion 12 is first inserted into the opening 211, and under the guidance of the guide surface structure 121, the first buckle body 11 is deformed by force until the limiting protrusion 12 completely passes through the opening 211, and the first buckle body 11 recovers its deformation, and the limiting protrusion 12 is locked with the edge of the opening 211. Then, at this time, the limiting structure 13 slides into the limiting groove 212, and the side wall of the limiting groove 212 limits the limiting structure 13; the limiting cooperation between the limiting structure 13 and the limiting groove 212 can limit the deflection of the first buckle 1 and the second buckle 2. For example, the limiting structure 13 is set to a columnar structure (shown in the figure), and the columnar structure is set parallel to the first buckle body 11. When the limiting protrusion 12 passes through the opening 211, the columnar structure is inserted into the limiting groove 212 to limit the displacement of the first buckle 1 and the second buckle 2.

[0055] The advantage of such a setting is that a limiting groove 212 is provided on the side wall of the opening 211, and the limiting protrusion 12 passes through the opening 211 and is engaged with the edge of the opening 211. At this time, the limiting structure 13 cooperates with the limiting groove 212 to achieve the limiting of the first buckle 1 and the second buckle 2. The first buckle 1 and the second buckle 2 are engaged with each other with high stability, not prone to deflection, high reliability and strong practicality.

[0056] like Figure 1 , Figure 2 , Figure 6 and Figure 7 , as shown, the limiting structure 13 is integrally connected with the first buckle body 11. For example, the limiting structure 13 and the first buckle body 11 are integrally injection molded or machined.

[0057] The advantage of such a configuration is that the structural rigidity of the first buckle body 11 is enhanced by integrally connecting the limiting structure 13 with the first buckle body 11 , and the overall structure of the buckle structure is compact, occupies little space, and is highly practical.

[0058] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the limiting groove 212 includes a first accommodating groove 2121, and the limiting structure 13 includes a limiting column 131, and the limiting column 131 is at least partially accommodated in the first accommodating groove 2121, and the first accommodating groove 2121 is used to limit the displacement of the first buckle 1 in the length direction of the limiting protrusion 12.

[0059] like Figure 2 , Figure 4 and Figure 6 As shown, it should be noted that the length direction of the limiting protrusion 12 and the width direction of the first buckle body 11 are both the X-axis direction in the accompanying drawings. When the limiting column 131 is accommodated in the first accommodating groove 2121, the side wall of the first accommodating groove 2121 along the length direction of the limiting protrusion 12 contacts the limiting column 131, thereby limiting the displacement of the buckle 1 in the length direction of the limiting protrusion 12.

[0060] The advantage of such a setting is that the limiting structure 13 includes a limiting column 131, and the cooperation between the first accommodating groove 2121 and the limiting column 131 limits the displacement of the first buckle 1 in the length direction of the limiting protrusion 12, thereby limiting the deflection of the first buckle 1. The connection between the first buckle 1 and the second buckle 2 is highly stable and practical.

[0061] like Figure 2 , Figure 4 and Figure 6 As shown, the limiting column 131 is located below the limiting protrusion 12 , and the limiting column 131 and the limiting protrusion 12 are located on the same side of the first buckle body 11 .

[0062] At this time, the limiting column 131 is at least partially located directly below the limiting protrusion 12. Here, the limiting column 131 and the limiting protrusion 12 are both located on the first buckle body 11 on the positive side of the Y axis. Compared with the limiting column 131 being arranged in other directions of the first buckle body 11, the limiting column 131 is less likely to affect the deformation of the first buckle body 11, and will not hinder the locking of the limiting protrusion 12 with the edge of the opening 211. It is highly practical.

[0063] The advantage of such a configuration is that the limiting column 131 is located below the limiting protrusion 12, and when the limiting protrusion 12 passes through the opening 211, the limiting protrusion 12 and the limiting column 131 move toward the direction close to the first receiving groove 2121, the limiting protrusion 12 is engaged with the edge of the opening 211, and the limiting column 131 slides into the first receiving groove 2121, the first buckle 1 and the second buckle 2 are stably connected, the first buckle 1 has a compact structure, high reliability, and strong practicality.

[0064] It should be noted that, in some embodiments, both ends along the length direction of the first buckle body 11 are set as open structures, and the limiting column 131 can be connected to the limiting protrusion 12, so that the strength of the limiting protrusion 12 can be strengthened. Of course, in order to ensure that the limiting protrusion 12 has a sufficiently large contact surface with the edge of the opening 211, the thickness of the end of the limiting column 131 connected to the limiting protrusion 12 can be smaller than the thickness at other positions; at this time, when the first buckle body 11 is inserted into the opening 211 and the limiting protrusion 12 begins to contact the edge of the opening 211, the limiting column 131 slides into the first accommodating groove 2121, and the first accommodating groove 2121 limits the displacement of the limiting column 131 along the width direction of the first buckle body 11; of course, the limiting column 131 can also be set at a preset distance from the limiting protrusion 12, which is not described in detail here.

[0065] like Figure 2 , Figure 4 and Figure 6 As shown, in the above embodiment, the orthographic projection of the limiting protrusion 12 on the cross section of the first buckle body 11 completely covers the orthographic projection of the limiting column 131 on the cross section of the first buckle body 11 .

[0066] It should be noted that the cross section of the first buckle body 11 is parallel to the XY plane. At this time, the limiting column 131 is located directly below the limiting protrusion 12, and the length of the limiting protrusion 12 is less than or equal to the width of the opening 211, so the width of the first accommodating groove 2121 is less than the width of the opening 211, that is, at this time, the first accommodating groove 2121 is arranged on the side wall of the opening 211 pointed by the protruding direction of the limiting protrusion 12, that is, it is arranged on the side wall along the positive direction of the Y axis, and is connected with the opening 211 along the Y axis direction.

[0067] The advantage of such a setting is that the width of the first accommodating groove 2121 can be smaller than the width of the opening 211, and the first accommodating groove 2121 only needs to be set on one side wall of the opening 211. When the first buckle body 11 is deformed and the limiting protrusion 12 is separated from the edge of the opening 211, the limiting column 131 directly detaches from the first accommodating groove 2121, and the limiting column 131 does not form a movement obstacle to the first buckle body 11. At the same time, the limiting column 131 does not exceed the edge of the limiting protrusion 12 along the protruding direction, ensuring that the limiting protrusion 12 and the edge of the opening 211 have a sufficient clamping surface, ensuring the strength of the clamping of the limiting protrusion 12 and the edge of the opening 211, and having high reliability and strong practicality.

[0068] In the above embodiment, the first receiving groove 2121 and the limiting column 131 are interference fit.

[0069] That is to say, when the first receiving groove 2121 and the limiting column 131 are in limiting cooperation, the first receiving groove 2121 has a tendency to hug the limiting column 131. At this time, the opening of the first receiving groove 2121 may have a certain elasticity, or a damping protrusion is provided at the opening of the first receiving groove 2121. In some embodiments, the opening width of the first receiving groove 2121 is smaller than the width of the limiting column 131. Here, when the limiting column 131 is located directly below the limiting protrusion 12, the width direction of the opening of the first receiving groove 2121 and the width direction of the limiting column 131 are both consistent with the X-axis direction in the accompanying drawings. For example, when the cross-sectional shape of the limiting column 131 is circular, the cross-sectional shape of the first receiving groove 2121 may be a sector with a central angle greater than 180 degrees, such as a sector with a central angle of 185 degrees.

[0070] The advantage of such a configuration is that, by arranging an interference fit between the first accommodating groove 2121 and the limiting column 131, when the first accommodating groove 2121 and the limiting column 131 are limitedly fitted, the first accommodating groove 2121 has a tendency to hold the limiting column 131 tightly, which can prevent the limiting column 131 and the first buckle body 11 from deformation to a certain extent, thereby improving the connection stability of the buckle structure.

[0071] In the above embodiment, the ratio of the length of the limiting column 131 to the length of the first buckle body 11 is between 1:1 and 1:5. For example, the ratio of the length of the limiting column 131 to the length of the first buckle body 11 is 1:4, 1:3 or 1:2.

[0072] That is to say, the length of the limiting column 131 is less than or equal to the length of the first buckle body 11. It should be noted that the length direction of the limiting column 131 is consistent with the length direction of the first buckle body 11, and the limiting column 131 is connected to the first buckle body 11. When the length of the limiting column 131 is less than the length of the first buckle body 11, the limiting column 131 plays a role of limiting cooperation with the first accommodating groove 2121. The position of the limiting column 131 in the length direction of the first buckle body 11 is not limited. It can be located at the end where the limiting protrusion 12 is located, for example, connected to the limiting protrusion 12; it can also be located at the end of the first buckle body 11 in the length direction away from the limiting protrusion 12; it can also be set in the middle of the first buckle body 11 in the length direction. When the length of the limiting column 131 is equal to the length of the first buckle body 11 , the limiting column 131 can also be connected to the limiting protrusion 12 , so as to enhance the overall structural rigidity of the limiting protrusion 12 and the first buckle body 11 and provide high stability.

[0073] The advantage of such a setting is that by setting different ratios of the length of the limiting column 131 to the length of the first buckle body 11, the first buckle body 11 can obtain different degrees of elasticity or limiting force. For example, when the length of the limiting column 131 is less than the length of the first buckle body 11, the first buckle body 11 maintains good elasticity and is convenient for snapping; when the length of the limiting column 131 is equal to the length of the first buckle body 11, the overall rigidity of the connection between the limiting protrusion 12 and the first buckle body 11 is enhanced, and the stability is high; and the length of the limiting column 131 will not exceed the length of the first buckle body 11, and the space occupied by the buckle structure is overall small, and the practicality is strong.

[0074] In the above embodiment, the cross-sectional shape of the limiting column 131 includes any one of a sector shape, a semicircle shape, a rectangle shape and a trapezoid shape.

[0075] The arc of the sector and the semicircle is located on the side of the limiting column 131 away from the buckle body 11, that is, on the side located in the positive direction of the Y axis in the figure; the upper bottom edge of the trapezoid is located on the side of the limiting column 131 away from the buckle body 11, so that it is convenient for the limiting column 131 to enter the first receiving groove 2121 along the height direction of the limiting protrusion 12. The contour of the first receiving groove 2121 matches the contour of the limiting column 131.

[0076] The advantage of such a configuration is that the cross-sectional shape of the limiting column 131 includes any one of a sector, a semicircle, a rectangle and a trapezoid, the first receiving groove 2121 has high reliability in limiting the limiting column 131, and when the cross-sectional shape of the limiting column 131 includes a sector, a semicircle, a rectangle or a trapezoid, the limiting column 131 has a certain sliding guide when entering the first receiving groove 2121, and has a simple structure and strong practicality.

[0077] It should be noted that the limiting column 131 and the first buckle body 11 are connected as one body, and in some embodiments, the limiting column 131 and the first buckle body 11 are a columnar structure, such as a cylindrical structure, so that the structure is simple, the processing and molding are convenient, and the use requirements can be met, and the practicability is strong.

[0078] like Figure 7 and Figure 8 As shown, in the above embodiment, the limiting structure 13 includes a limiting seat 132, the limiting seat 132 is connected to the first buckle body 11, the limiting groove 212 includes a second accommodating groove 2122, and the limiting seat 132 is plugged and matched with the second accommodating groove 2122 along the direction in which the first buckle body 11 is inserted into the opening 211.

[0079] It should be noted that the limiting seat 132 is located at one end of the first buckle body 11 in the length direction away from the limiting protrusion 12, or at the end of one end away from the limiting protrusion 12. In this way, the first buckle 1 has a simple structure and is easy to form. At this time, the limiting seat 132 can be a cylindrical structure or a prismatic structure, which is not a limitation.

[0080] The second accommodating groove 2122 is arranged as an open structure at one end close to the first buckle 1, that is, the limiting groove 212 penetrates the second buckle body 21 in the reverse direction along the Z axis. In the present embodiment, the second accommodating groove 2122 is arranged circumferentially along the opening 211, that is, the contour line of the cross section of the second accommodating groove 2122 is arranged around the contour line of the cross section of the opening 211; the side wall of the second accommodating groove 2122 is in contact with the circumferential surface of the limiting seat 132.

[0081] It should be noted that in order to ensure that the limiting protrusion 12 can smoothly pass through the opening 211 and engage with the edge of the opening 211, a sufficient distance should be maintained between the limiting seat 132 and the limiting protrusion 12 along the length direction of the first buckle body 11, so that the first buckle body 11 can undergo a certain degree of deformation, thereby facilitating the insertion of the limiting protrusion 12 into the opening 211.

[0082] The advantage of such a configuration is that the limiting seat 132 and the second accommodating groove 2122 are provided, and the limiting seat 132 is plugged into and cooperates with the second accommodating groove 2122 along the direction in which the first buckle body 11 is inserted into the opening 211, so as to realize the limiting of the first buckle 1 in any direction within the cross section of the first buckle body 11, and the positioning between the first buckle 1 and the second buckle 2 is more reliable, and the first buckle 1 and the second buckle 2 are not prone to deflection, with high reliability and strong practicality.

[0083] like Figure 7 and Figure 8 As shown, in some embodiments, the limiting seat 132 is a truncated cone structure or a prism structure, and the second receiving groove 2122 matches the limiting seat 132 .

[0084] It should be noted that the large end of the truncated cone structure or the prism structure is located at an end of the first buckle body 11 away from the limiting protrusion 12, that is, the end located in the Z-axis direction in the drawings.

[0085] The advantage of such a setting is that the limit seat 132 is a truncated cone or a prism-shaped structure, and the inclined surface of the truncated cone or the prism-shaped structure can guide the limit seat 132 to be inserted into the second accommodating groove 2122, which is convenient for plugging in. In addition, the inclined surface of the truncated cone or the prism-shaped structure can limit the first buckle body 11 to a certain extent from continuing to move in the direction in which the first buckle body 11 is inserted into the opening 211, causing the limit protrusion 12 to separate from the edge of the opening 211.

[0086] In some embodiments, the second receiving groove 2122 is connected to the first receiving groove 2121, and at this time, the limiting seat 132 can be connected to the limiting column 131, and the projection of the limiting column 131 in the cross section of the first buckle body 11 is completely covered by the projection of the limiting seat 132 in the cross section of the first buckle body 11. At this time, the second receiving groove 2122 positions the first buckle 1 as a whole, and the first receiving groove 2121 positions the first buckle body 11 along the width direction and strengthens the bending resistance of the first buckle body 11. The structure of the first buckle 1 and the second buckle 2 is stable and highly reliable.

[0087] like Figure 8 As shown, in the above embodiment, in order to reduce the mass of the limiting seat 132, the limiting seat 132 can be set as a hollow structure, and a reinforcing structure such as reinforcing ribs can be set inside the hollow structure, which will not be described in detail here.

[0088] like Fig. 9As shown, the snap structure further includes a limiting member 3, which is detachably connected to the first snap body 11 and the second snap 2 respectively. The limiting member 3 is used to limit the separation of the limiting protrusion 12 from the opening 211.

[0089] It should be noted that the limiting member 3 is detachably connected to the first snap body 11 and the second snap 2 respectively, and it can be any one of snap connection, plug connection or screw connection. The limiting member 3 is used to limit the movement of the limiting protrusion 12 along the side opposite to the protruding direction of the limiting protrusion 12. The protruding direction is the positive direction of the Y-axis in the drawing, and the limiting member 3 is used to limit the movement of the limiting protrusion 12 along the reverse direction of the Y-axis.

[0090] As Fig. 9 、 Fig.10 、 Fig.11 and Fig.12 As shown in [relevant figures], in some embodiments, one end of the limiting member 3 is rotatably connected to the first snap body 11, and the other end of the limiting member 3 is snap-connected to the second snap 2.

[0091] At this time, the limiting member 3 is rotatably connected to the end of the first snap body 11 where the limiting protrusion 12 is located. The second snap 2 includes a limiting portion 22, which is arranged on the second snap body 21. The limiting portion 22 is snap-connected to the limiting member 3. In this specification, the case where the limiting portion 22 is located in the reverse direction of the Y-axis of the opening 211 is taken as an example for illustration, but it can also be arranged in another direction.

[0092] In this embodiment, after the limiting protrusion 12 is snap-connected to the edge of the opening 211, rotate the limiting member 3 in the YZ plane so that the limiting member 3 is snap-connected to the limiting portion 22, thereby restricting the limiting protrusion 12 from disengaging from the opening 211; rotate the limiting member 3 in the reverse direction. After the limiting member 3 is separated from the limiting portion 22, the limiting protrusion 12 and the opening 211 may be separated. The limiting member 3 can realize the locking of the snap connection between the limiting protrusion 12 and the edge of the opening 211.

[0093] As Fig. 9 As shown in [relevant figure], in some embodiments, the limiting member 3 has a C-shaped structure, or in other words, a U-shaped structure 311. The two ends of the U-shaped structure 311 are the two opposite sides of the U-shaped structure 311 respectively. One end of the U-shaped structure 311 is rotatably connected to the first snap body 11, and the other end of the U-shaped structure 311 is snap-connected to the limiting portion 22. For example, the second snap body 21 is provided with a mounting hole along the width direction, and one end of the U-shaped structure 311 is inserted into the mounting hole and rotatably connected to the mounting hole.

[0094] As Fig.13 As shown, in some embodiments, the limiting member 3 may include two U-shaped structures 311, and the two U-shaped structures 311 are respectively located on both sides of the first snap body 11 in the width direction; a frame structure 31 with an opening may be further integrally formed between the two U-shaped structures 311. At this time, the limiting member 3 can also be used as a pull ring to pull the limiting protrusion 12, with high reliability and strong practicability.

[0095] Of course, the connection method of the limiting member 3 can also be that one end of the limiting member 3 is snap-connected to the first snap body 11, and the other end of the limiting member 3 is rotatably connected to the second snap 2, which will not be elaborated here.

[0096] The advantage of such a setting is that the limiting member 3 is detachably connected to the first snap body 11 and the second snap 2 respectively. The limiting member 3 is used to limit the separation of the limiting protrusion 12 from the opening 211. Only when the limiting member 3 releases the restriction on the limiting protrusion 12 can the limiting protrusion 12 be separated from the edge of the opening 211. The first snap 1 and the second snap 2 are not easily disengaged, with high stability and strong practicability.

[0097] As Figure 1 As shown, in another embodiment of the present invention, a display box installation structure is provided, including any one of the above-mentioned snap structures, and further including a panel 4 and a display box 5. The panel 4 includes a panel body 41, and the display box 5 includes a display box body 51; the first snap 1 of the snap structure is provided on the panel body 41, and the second snap 2 of the snap structure is provided on the display box body 51.

[0098] It should be noted that the first snap 1 is provided on the inner side of the panel body 41, that is, on the positive side of the Z axis in the drawing. The number and position of the snap structures can be determined according to actual installation requirements, and can also cooperate with other structures to realize the connection between the display box 5 and the panel 4.

[0099] The advantage of such a setting is that the connection between the panel 4 and the display box 5 is realized through the snap structure, which can not only realize the connection between the panel 4 and the display box 5, but also limit the deflection of the display box 5 to a certain extent, with convenient disassembly and high reliability.

[0100] As Figure 1 As shown, in some embodiments, the display box 5 further includes an insertion piece structure 6. The insertion piece structure 6 is provided at one end of the display box body 51, and the panel body 41 is provided with a slot structure 7. The insertion piece structure 6 is inserted and matched with the slot structure 7.

[0101] Here, the slot structure 7 is located at the inner side of the panel body 41, and the direction in which the inserting piece structure 6 is inserted into the slot structure 7 is perpendicular to the direction in which the first buckle body 11 is inserted into the opening 211, and the direction in which the inserting piece structure 6 is inserted into the slot structure 7 is opposite to the Y-axis direction in the figure. When installing the display box 5, first insert the inserting piece structure 6 into the slot structure 7 to position the display box 5, and then press the display box 5, so that the limiting protrusion passes through the opening 211 and engages with the edge of the opening 211, so that the display box 5 is reliably installed.

[0102] The advantage of such a configuration is that the display box 5 is positioned by the insertion cooperation between the insert structure 6 and the slot structure 7; and the display box 5 and the panel 4 are locked by the buckle structure, so that the assembly is quick and convenient, the number of screws used is reduced, the reliability is high, and the practicability is strong.

[0103] like Figure 1 As shown, the second buckle 2 is disposed at the other end of the display box body 51 , and the limiting protrusion 12 of the first buckle 1 is located at an end of the first buckle body 11 of the first buckle 1 away from the slot structure 7 .

[0104] It should be noted that if Figure 5 As shown, for the sake of aesthetic design or space requirements, the panel 4 is configured as an outwardly protruding arc structure, so when assembling, if the panel 4 is subjected to a pressing force, the distance between the first buckle 1 and the slot structure 7 may increase, and the first buckle 1 may be disengaged. When installing the display box 5, first insert the insert structure 6 into the slot structure 7, and then press the end of the display box 5 where the second buckle 2 is located, so that the first buckle 1 and the second buckle 2 are clamped.

[0105] The advantage of such a configuration is that the display box can be assembled quickly and conveniently, and the limiting protrusion 12 of the first buckle 1 is located on the side of the first buckle body 11 away from the slot structure 7, so that when the panel 4 is an arc-shaped structure protruding outward, the limiting protrusion 12 and the opening 211 will not be separated due to the inward pressing force on the panel 4, which has high reliability and strong practicality.

[0106] It should be noted that in the above embodiment, the display box 5 and the panel 4 can be further locked by screws. For example, a threaded hole structure 411 is provided on the panel body 41, and a through hole structure 511 is provided on the display box body 51. The display box mounting structure also includes a fastener, and the fastener passes through the through hole structure 511 and is threadedly connected to the threaded hole structure 411. Here, the position of the through hole structure 511 is not limited, and it can be located at the end where the second buckle 2 is located. The advantage of such a setting is that by providing the fastener, the stability and reliability of the connection between the display box 5 and the panel 4 are higher.

[0107] Another embodiment of the present invention provides an air conditioner, the air conditioner comprising any one of the above-mentioned buckle structures. The air conditioner has the beneficial effects of the buckle structure, which will not be described in detail here.

[0108] 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.
