Abstract

This invention provides a rotating latch and an air conditioner, relating to the field of air conditioning technology. The rotating latch includes a latch body, a latch mounting base, and a rotating connecting rod. The latch body is rotatably mounted on the latch mounting base and engages with a latch hole on the middle frame. One end of the rotating connecting rod is drively connected to the latch body, driving the latch body to rotate relative to the latch mounting base, thereby disengaging the latch body from the latch hole. During disassembly, by moving the rotating connecting rod, the latch body rotates relative to the latch mounting base, disengaging the latch body from the latch hole, and thus allowing the middle frame to detach from the base, achieving disassembly of the middle frame. Compared to existing technologies, the rotating latch provided by this invention allows the latch body to disengage from the latch hole through rotation, enabling the middle frame to detach from the base, facilitating the disassembly of the middle frame.

Description

Technical Field

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

[0002] After long-term use, a lot of dirt accumulates inside the air conditioner, which leads to odor and reduced cooling effect. However, traditional air conditioners are not easy to disassemble for cleaning, so easy-to-disassemble and clean air conditioners are gradually emerging in the market. However, most air conditioners use a latch structure between the middle frame and the base, which requires a certain angle and strong pulling to remove, making it very difficult to disassemble the middle frame and providing a very poor experience. Summary of the invention

[0003] The problem solved by the present invention is how to conveniently disassemble and assemble the middle frame.

[0004] To solve the above problems, the present invention adopts the following technical solutions.

[0005] On the one hand, the present invention provides a rotating buckle, including a buckle body, a buckle mounting seat and a rotating connecting rod. The buckle body is rotatably set on the buckle mounting seat for cooperating with a buckle hole on a middle frame. One end of the rotating connecting rod is transmission-connected with the buckle body for driving the buckle body to rotate relative to the buckle mounting seat so that the buckle body can be disengaged from the buckle hole.

[0006] The present invention provides a rotating buckle, which is arranged on the buckle mounting seat by rotating the buckle body, and one end of the rotating connecting rod is connected to the buckle body by transmission. When assembling, the buckle body is matched with the clamping hole on the middle frame, so that the base and the middle frame can be clamped together. When disassembling, the buckle body is disengaged from the clamping hole by turning the rotating connecting rod, and the buckle body is driven to rotate relative to the buckle mounting seat by the rotating connecting rod, so that the buckle body is disengaged from the clamping hole, and then the middle frame can be disengaged from the base, so as to realize the disassembly of the middle frame. Compared with the prior art, the rotating buckle provided by the present invention can disengage the buckle body from the clamping hole by rotating, so that the middle frame can be disengaged from the base, and the disassembly of the middle frame is convenient.

[0007] Furthermore, the buckle body includes a seat body and a latch tongue. The seat body is rotatably set on the buckle mounting seat. The rotating connecting rod is transmission-connected to the seat body and movably connected to the buckle mounting seat, so as to drive the seat body to rotate relative to the buckle mounting seat. The latch tongue is set on the outer peripheral wall of the seat body and extends outward, so as to cooperate with the buckle.

[0008] The rotatable buckle provided by the present invention achieves cooperation with the buckle hole through the buckle tongue, and the buckle effect is better. The seat body is rotatably set on the buckle mounting seat, and the seat body is driven to rotate by rotating the connecting rod, and the buckle tongue is driven to disengage from the buckle hole, so that the controllability is better.

[0009] Furthermore, the tongue has relative upper and lower surfaces, the lower surface is flush with the lower surface of the seat body close to the snap mounting seat, the upper surface is inclined, and the height of the side of the upper surface away from the seat body relative to the lower surface is lower than the height of the side of the upper surface close to the seat body relative to the lower surface.

[0010] The rotating buckle provided by the present invention sets the upper surface of the tongue into an inclined surface. During assembly, the middle frame is directly pressed down along the upper surface to achieve engagement with the tongue. The upper surface can play a guiding role, facilitating assembly of the middle frame.

[0011] Furthermore, a transmission hole is opened on the seat body, one end of the rotating connecting rod passes through the transmission hole and cooperates with the transmission hole, and the end of the rotating connecting rod passing through the transmission hole is movably connected to the buckle mounting seat.

[0012] The rotary buckle provided by the present invention has a transmission hole on the seat body, and the rotary connecting rod passes through the transmission hole and cooperates with the transmission hole, so that the rotary connecting rod can rotate synchronously with the seat body, the transmission effect is stable, and slipping or incomplete rotation can be avoided.

[0013] Furthermore, the transmission hole is a hexagonal hole, and the rotating connecting rod is assembled in the transmission hole.

[0014] The rotary buckle provided by the present invention has a transmission hole which is a hexagonal hole, and the shape of the rotary connecting rod matches the transmission hole, so the transmission effect is good.

[0015] Furthermore, the snap-on mounting seat includes a base plate and a limiting plate, the seat body is rotatably connected to the base plate, the rotating connecting rod is movably connected to the base plate, and the limiting plate is arranged on the base plate for limiting the seat body.

[0016] The rotating buckle provided by the present invention can limit the position of the seat body on the bottom plate by setting a limit plate, thereby preventing the seat body from moving around and ensuring that the buckle between the clamping tongue and the clamping hole on the middle frame is firm.

[0017] Furthermore, the cross section of the limiting plate is in a semi-ring shape.

[0018] Furthermore, a plurality of limit spring buckles are arranged on the limit plate, a clamping space is formed between the plurality of limit spring buckles and the bottom plate, the seat body is arranged in the clamping space, and the plurality of limit spring buckles are used to abut against the upper surface of the seat body away from the bottom plate.

[0019] The rotating buckle provided by the present invention further limits the seat body by providing a plurality of limit spring buckles, and the plurality of limit spring buckles are used to abut against the upper surface of the seat body, thereby ensuring that the seat body does not move in the vertical direction and ensuring the fixing effect between the middle frame and the base.

[0020] Furthermore, a plurality of clearance holes are opened on the limit plate, and a plurality of limit spring buckles are arranged in the plurality of clearance holes in a one-to-one correspondence. Each limit spring buckle includes a spring sheet and a limit protrusion protruding from the spring sheet. The spring sheet is fixedly connected to the limit plate, and the limit protrusion is used to abut against the upper surface of the seat body away from the bottom plate.

[0021] The rotary buckle provided by the present invention has a spring sheet and a limiting protrusion, so that the limiting spring buckle has a certain elasticity. When the seat body is installed, the spring sheet can be deformed, which facilitates the installation of the seat body into the clamping space.

[0022] Furthermore, the limiting protrusion has a relative abutting surface and a guiding surface, the abutting surface is used to abut against the seat body, the guiding surface is inclined, and the height of the side of the guiding surface away from the spring sheet relative to the abutting surface is smaller than the height of the side of the guiding surface close to the spring sheet relative to the abutting surface.

[0023] The rotating buckle provided by the present invention, by providing a supporting surface, enables the limiting protrusion to better support on the seat body. At the same time, by providing a guide surface, the seat body can slide down along the guide surface when installed in the seat body, and the spring sheet can be deformed, so that the seat body can be easily installed in the clamping space.

[0024] Furthermore, a plurality of guide protrusions are arranged on the bottom plate, and the plurality of guide protrusions are arranged along the same circumference. A guide ring groove is opened on the lower surface of the seat body close to the bottom plate, and the plurality of guide protrusions are accommodated in the guide ring groove.

[0025] The rotating buckle provided by the present invention is provided with a plurality of guide protrusions and a guide ring groove is opened on the lower surface of the seat body. The cooperation between the guide ring groove and the guide protrusions allows the seat body to rotate only along the circumference where the plurality of guide protrusions are located, thereby guiding the rotation of the seat body and ensuring that the latch tongue can be separated from the latch hole.

[0026] Furthermore, a connecting hole is provided on the bottom plate, and the rotating connecting rod passes through the connecting hole and is rotatably connected to the bottom plate. A supporting piece is also provided at the end of the rotating connecting rod passing through the connecting hole, and the supporting piece is used to support against the bottom plate.

[0028] Furthermore, a rotating handle is provided at one end of the rotating connecting rod away from the buckle mounting seat.

[0029] The rotary buckle provided by the present invention is very convenient because a rotary handle is provided and the rotary handle can be directly turned when rotating.

[0031] The rotary buckle provided by the present invention provides a bracket and fixes the rotary connecting rod through an elastic slot on the bracket to prevent the rotary connecting rod from moving and avoid the rotary connecting rod from tilting to affect the rotation of the buckle body.

[0032] Furthermore, the two sides of the elastic slot are provided with clearance grooves, so that the two side walls of the elastic slot can be deformed to the two sides when the rotating connecting rod is installed.

DETAILED DESCRIPTION

[0046] 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.

[0047] First embodiment

[0048] See also Figures 1 to 4 The present embodiment provides a rotatable buckle 100, which replaces the traditional latch fixing structure between the middle frame 200 and the base by rotating, so that the buckle structure on the base can be rotated. When disassembling, the buckle structure is rotated to disengage it from the middle frame 200, which facilitates the disassembly of the middle frame 200 and is easy to operate.

[0049] The rotating buckle 100 provided in this embodiment includes a buckle body 110, a buckle mounting seat 130 and a rotating connecting rod 150. The buckle body 110 is rotatably set on the buckle mounting seat 130 for cooperating with the buckle hole on the middle frame 200. One end of the rotating connecting rod 150 is transmission-connected to the buckle body 110 for driving the buckle body 110 to rotate relative to the buckle mounting seat 130 so that the buckle body 110 can be disengaged from the buckle hole.

[0050] In this embodiment, the snap-on mounting seat 130 is fixed on the base of the air conditioner, and a snap hole is opened on the middle frame 200. Through the cooperation between the snap-on body 110 and the snap-on hole, the middle frame 200 can be assembled with the base. When disassembling, the connecting rod 150 is turned and rotated, and the snap-on body 110 is driven to rotate relative to the snap-on mounting seat 130 by rotating the connecting rod 150, so that the snap-on body 110 is disengaged from the snap hole, and then the middle frame 200 can be disengaged from the base, thereby realizing the disassembly of the middle frame 200.

[0051] In this embodiment, the rotating connecting rod 150 is a metal rod, and it is accommodated in the base. The end of the rotating connecting rod 150 away from the buckle body 110 passes through the base, which is convenient for direct manipulation by hand. Specifically, the buckle mounting seat 130 is arranged on the top side of the base, and the rotating connecting rod 150 passes through the base and passes through the bottom of the base. In actual use, it is very convenient to manipulate the rotating connecting rod 150 from the bottom of the base.

[0052] In this embodiment, a rotating handle 170 is provided at one end of the rotating connecting rod 150 away from the buckle mounting seat 130. By providing the rotating handle 170, it is very convenient to directly turn the rotating handle 170 when rotating. Specifically, the extending direction of the rotating handle 170 is perpendicular to the extending direction of the rotating connecting rod 150. When the middle frame 200 needs to be disassembled, it is only necessary to hold the rotating handle 170 and rotate it in a clockwise or counterclockwise direction (depending on the installation direction) to disengage the buckle body 110 from the clamping hole, and then the middle frame 200 can be disassembled.

[0053] Furthermore, the rotating buckle 100 further includes a bracket 190, on which an elastic slot 191 is provided, and the elastic slot 191 cooperates with an end of the rotating connecting rod 150 away from the buckle mounting seat 130, and is used to limit the rotating connecting rod 150. By providing the bracket 190 and fixing the rotating connecting rod 150 through the elastic slot 191 on the bracket 190, the rotating connecting rod 150 is prevented from moving, and the rotating connecting rod 150 is prevented from tilting, thereby affecting the rotation of the buckle body 110.

[0054] It should be noted that, in this embodiment, the elastic slot 191 is in a V-shaped structure, and a round hole matching the size of the rotating connecting rod 150 is provided at the bottom of the V-shaped structure, so that a reasonable guiding effect can be achieved through the V-shaped structure.

[0055] In this embodiment, the two sides of the elastic slot 191 are provided with clearance grooves 193, so that the two side walls of the elastic slot 191 can be deformed to the two sides when the rotating connecting rod 150 is installed. Specifically, by providing the clearance grooves 193, the two side walls of the elastic slot 191 constitute elastic ribs, which can be deformed to the two sides, and the two side walls of the elastic slot 191 can be deformed to the two sides when the rotating connecting rod 150 is installed, so that the rotating connecting rod 150 can be easily installed in the elastic slot 191.

[0056] See also Figure 5 and Figure 6The buckle body 110 includes a seat body 111 and a latch 113. The seat body 111 is rotatably arranged on the buckle mounting seat 130. The rotating connecting rod 150 is transmission-connected with the seat body 111 and movably connected with the buckle mounting seat 130, and is used to drive the seat body 111 to rotate relative to the buckle mounting seat 130. The latch 113 is arranged on the outer peripheral wall of the seat body 111 and extends outward, and is used to cooperate with the buckle. Specifically, the size of the latch 113 is smaller than the size of the clamping hole, so that there is a certain rotation gap between the latch 113 and the side wall of the clamping hole, which facilitates the latch 113 to rotate out of the clamping hole. The latching effect is better by realizing the cooperation with the clamping hole through the latch 113, and the seat body 111 is rotatably arranged on the buckle mounting seat 130, and the seat body 111 is driven to rotate by the rotating connecting rod 150, and the latch 113 is driven to escape from the clamping hole, so that the controllability is better.

[0057] In this embodiment, the seat body 111 is cylindrical and can rotate driven by the rotating connecting rod 150. Of course, the seat body 111 can also be other shapes, such as a semi-cylindrical or fan-shaped column, etc., which is not specifically limited here.

[0058] In this embodiment, the latch tongue 113 has an upper side surface and a lower side surface relative to each other, the lower side surface is flush with the lower surface of the base body 111 close to the buckle mounting seat 130, the upper side surface is in an inclined shape, and the height of the side of the upper side surface away from the base body 111 relative to the lower side surface is lower than the height of the side of the upper side surface close to the base body 111 relative to the lower side surface. The upper side surface of the latch tongue 113 is set to be in an inclined shape, and the middle frame 200 is directly pressed down along the upper side surface during assembly to achieve buckling with the latch tongue 113. The upper side surface can play a guiding role, which facilitates the assembly of the middle frame 200.

[0059] In this embodiment, the lower surface of the tongue 113 is flush with the horizontal plane and the lower surface of the base 111, so that the base 111 and the tongue 113 can fit on the installation plane of the buckle mounting seat 130, and the tongue 113 extends outward in the radial direction of the base 111, so that the middle frame 200 is not easy to fall off after installation. At the same time, the upper surface of the tongue 113 is inclined at an angle of 45° compared to the lower surface, presenting a slope structure, which is easy to install when matched with the middle frame 200.

[0060] The seat body 111 is provided with a transmission hole 115, one end of the rotating connecting rod 150 passes through the transmission hole 115 and matches with the transmission hole 115, and one end of the rotating connecting rod 150 passing through the transmission hole 115 is movably connected to the buckle mounting seat 130. By providing the transmission hole 115 on the seat body 111, and the rotating connecting rod 150 passing through the transmission hole 115 and matching with the transmission hole 115, the rotating connecting rod 150 can rotate synchronously with the seat body 111, the transmission effect is stable, and the situation of slipping or not rotating in place can be avoided.

[0061] In this embodiment, the transmission hole 115 is a hexagonal hole, and the rotating connecting rod is assembled in the transmission hole 115. The shape of the rotating connecting rod matches the transmission hole 115, and the transmission effect is good. Specifically, the part of the rotating connecting rod that is assembled with the transmission hole 115 is an outer hexagonal column structure, so that it can match the transmission hole 115 with an inner hexagonal structure.

[0062] See also Figures 7 to 9 The buckle mounting seat 130 includes a bottom plate 131 and a limiting plate 133. The seat body 111 is rotatably connected to the bottom plate 131. The rotating connecting rod 150 is movably connected to the bottom plate 131. The limiting plate 133 is arranged on the bottom plate 131 to limit the seat body 111. By setting the limiting plate 133, the seat body 111 can be limitedly arranged on the bottom plate 131 to prevent the seat body 111 from running around, and ensure that the buckle between the locking tongue 113 and the locking hole on the middle frame 200 is firm.

[0063] In this embodiment, the cross section of the limiting plate 133 is in a semi-ring shape. Specifically, the limiting plate 133 is in a semi-cylindrical shape as a whole, and is integrally formed with the bottom plate 131, and the bottom plate 131 is fixedly arranged on the base. Of course, in other preferred embodiments, the limiting plate 133 can also be in other shapes such as a rectangular cylinder or a V-shaped cylinder, which is not specifically limited here.

[0064] It should be noted that, in the present embodiment, the right end face of the limit plate 133 is flush with the end face of the base plate 131, and the left end face is located on the upper side face of the base plate 131, so that when the buckle body 110 rotates, the latch tongue 113 rotates toward the left, and a clearance space is formed at the left end face of the limit plate 133 for accommodating the latch tongue 113 to avoid interference with the rotation of the latch tongue 113.

[0065] In this embodiment, a plurality of limiting spring buckles 135 are provided on the limiting plate 133, a clamping space is formed between the plurality of limiting spring buckles 135 and the bottom plate 131, the base 111 is provided in the clamping space, and the plurality of limiting spring buckles 135 are used to abut against the upper surface of the base 111 away from the bottom plate 131. By providing a plurality of limiting spring buckles 135, and the plurality of limiting spring buckles 135 are used to abut against the upper surface of the base 111, the base 111 is further limited, ensuring that the base 111 does not move in the vertical direction, and ensuring the fixing effect between the middle frame 200 and the base.

[0066] The limiting plate 133 is provided with a plurality of clearance holes 137, and a plurality of limiting spring buckles 135 are arranged in the plurality of clearance holes 137 in a one-to-one correspondence. Each limiting spring buckle 135 includes a spring piece 1351 and a limiting protrusion 1353 protruding from the spring piece 1351. The spring piece 1351 is fixedly connected to the limiting plate 133, and the limiting protrusion 1353 is used to abut against the upper surface of the seat body 111 away from the bottom plate 131. By providing the spring piece 1351 and the limiting protrusion 1353, the limiting spring buckle 135 has a certain elasticity. When the seat body 111 is installed, the spring piece 1351 can be deformed, so that the seat body 111 can be easily installed into the clamping space.

[0067] In this embodiment, there are three clearance holes 137 and three limiting spring buckles 135. The three clearance holes 137 are distributed in a triangular shape on the side wall of the limiting plate 133, and the three limiting spring buckles 135 are distributed in the three clearance holes 137, thereby forming a triangular structure, which makes the supporting and limiting effects better.

[0068] In this embodiment, the limiting protrusion 1353 has a relative abutting surface and a guiding surface, the abutting surface is used to abut against the seat body 111, the guiding surface is in the shape of an inclined surface, and the height of the side of the guiding surface away from the elastic sheet 1351 relative to the abutting surface is less than the height of the side of the guiding surface close to the elastic sheet 1351 relative to the abutting surface. By providing the abutting surface, the limiting protrusion 1353 can be better abutted against the seat body 111, and by providing the guiding surface, when the seat body 111 is installed, the seat body 111 can slide down along the guiding surface, and the elastic sheet 1351 is deformed, so that the seat body 111 is conveniently installed in the clamping space.

[0069] It should be noted that, in this embodiment, the supporting surface is parallel to the upper side surface of the base plate 131, and the distance between the supporting surface and the upper side surface of the base plate 131 is slightly larger than the thickness of the seat body 111, so that the seat body 111 can rotate freely in the clamping space, and can also be limited. Specifically, the supporting surface cooperates with the upper surface of the seat body 111 to form a dead lock, so that the seat body 111 is fixed more firmly in the vertical direction and is not easy to move.

[0070] It should also be noted that in this embodiment, the supporting surface is parallel to the horizontal plane, and the inclination angle of the guide surface relative to the horizontal plane is 60°, which facilitates the installation of the seat body 111.

[0071] In this embodiment, a plurality of guide protrusions 139 are further provided on the bottom plate 131, and the plurality of guide protrusions 139 are provided along the same circumference. A guide ring groove is provided on the lower surface of the seat body 111 close to the bottom plate 131, and the plurality of guide protrusions 139 are accommodated in the guide ring groove. By providing a plurality of guide protrusions 139 and providing a guide ring groove on the lower surface of the seat body 111, the seat body 111 can only rotate along the circumference where the plurality of guide protrusions 139 are located through the cooperation between the guide ring groove and the guide protrusions 139, thereby guiding the rotation of the seat body 111 and ensuring that the latch tongue 113 can be separated from the latch hole.

[0072] In this embodiment, there are three guide protrusions 139, and the guide ring groove is set on the lower surface of the seat body 111. The three guide protrusions 139 form a triangular structure, which makes the guiding effect better. It is worth noting that the guide protrusions 139 here are rectangular blocks, and their size is small, which will not cause a large obstruction to the rotation of the seat body 111. In other preferred embodiments, the guide protrusions 139 can be round protrusions, which further reduce the friction between the seat body 111 and the guide protrusions 139.

[0073] The bottom plate 131 is also provided with a connection hole 138, through which the rotation connecting rod 150 passes and is rotationally connected to the bottom plate 131, and a supporting member 151 is provided at the end of the rotation connecting rod 150 passing through the connection hole 138, and the supporting member 151 is used to support the bottom plate 131. The bottom plate 131 is provided with a connection hole 138, through which the rotation connecting rod 150 passes and is rotationally connected to the bottom plate 131, and is supported by the supporting member 151 on the bottom plate 131, which can ensure that the rotation connecting rod 150 and the bottom plate 131 can rotate freely while preventing the rotation connecting rod 150 from coming out of the connection hole 138.

[0074] In this embodiment, the abutment 151 is a nut, and the end of the rotating connecting rod 150 is provided with an external thread, and the rotating connecting rod 150 is limited by the nut to prevent the rotating connecting rod 150 from being separated from the bottom plate 131. Of course, other types of abutment 151 may also be used here, such as a nut or a pin, and the abutment 151 and the rotating connecting rod 150 may also be connected in other detachable forms such as a snap connection or a plug connection, which is not specifically limited here.

[0075] In summary, the present embodiment provides a rotating buckle 100, which connects the buckle body 110 on the base with the buckle hole on the middle frame 200 through a rotating connection. When the middle frame 200 needs to be disassembled, it is only necessary to rotate the buckle body 110 and disengage it from the buckle hole, which is very convenient. During actual assembly, since the upper surface of the tongue 113 is in an inclined shape, the buckle hole on the middle frame 200 can be easily matched with the buckle body 110. During actual disassembly, the rotating handle 170 is held and rotated, and the buckle body 110 also rotates, and the tongue 113 is disengaged from the buckle hole, and the middle frame 200 is completely separated from the base, and there is no motion interference between the two. The middle frame 200 can be easily taken out, which greatly facilitates the disassembly of the middle frame 200.

[0076] Second embodiment

[0077] The present embodiment provides an air conditioner, including a middle frame 200, a base and a rotatable buckle 100, wherein the basic structure and principle of the rotatable buckle 100 and the technical effect produced are the same as those of the first embodiment. For the sake of brief description, for parts not mentioned in this embodiment, reference may be made to the corresponding contents in the first embodiment.

[0078] The rotating buckle 100 includes a buckle body 110, a buckle mounting seat 130 and a rotating connecting rod 150. The buckle body 110 is rotatably set on the buckle mounting seat 130 for cooperating with the buckle hole on the middle frame 200. One end of the rotating connecting rod 150 is transmission-connected to the buckle body 110 for driving the buckle body 110 to rotate relative to the buckle mounting seat 130 so that the buckle body 110 can be disengaged from the buckle hole.

[0079] In this embodiment, the snap-on mounting seat 130 is fixed on the base of the air conditioner, and a snap hole is opened on the middle frame 200. Through the cooperation between the snap-on body 110 and the snap-on hole, the middle frame 200 can be assembled with the base.
