Description

Technical Field

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

[0002] The current installation method for mesh parts such as filters is generally to set a plug-in on the edge of the mesh part, set a slot on a fixed object such as a middle frame, and use the feature that the mesh part can undergo a certain deformation. During installation, the plug-in is inserted into the slot, and the mesh part is installed through extrusion, deformation, and deformation recovery. However, this method is time-consuming and laborious to disassemble and assemble, and it is easy for the mesh part to be unable to recover to its original shape due to repeated bending. Summary of the invention

[0003] The problem solved by the invention is that the existing installation method of mesh parts has the disadvantages of being time-consuming and labor-intensive, and the mesh parts being damaged.

[0004] In order to solve at least one aspect of the above problems, the present invention provides a turn-lock structure, including: a turn-lock and a turn-lock mating part, the turn-lock mating part is formed with a mating surface suitable for rotationally mating with the turn-lock, the mating surface includes a first mating surface and a second mating surface, and the first mating surface is arranged to protrude from the second mating surface.

[0005] The present invention installs a to-be-fixed part such as a filter screen on a fixed object, or releases the to-be-fixed part from the fixed object, through the rotational cooperation between the turn button and the turn button matching part. The disassembly and assembly method is simple, and the rotational fixing method saves time and effort. The to-be-fixed part is not easy to bend and deform, and the service life of the to-be-fixed part is improved. By setting a first matching surface and a second matching surface with a thickness difference, the force required to overcome when the turn button is matched with the first matching surface is larger, the force required to rotate the turn button is larger, and the turn button feels tighter when rotating. The force required to overcome when the turn button is matched with the second matching surface is smaller, the force required to rotate the turn button is smaller, and the turn button feels looser when rotating. The tightness of the turn button during rotation is adjusted, thereby achieving the effect of saving effort during the rotation of the turn button and firmly fixing the turn button.

[0006] Further, the turn-on fitting part includes a turn-on fitting part body and a protruding rib, the protruding rib is arranged on the side of the turn-on fitting part body away from the turn buckle, and the protruding rib forms the first mating surface and the second mating surface respectively on the side of the turn-on fitting part body away from the turn buckle, and the thickness of the protruding rib at the first mating surface is greater than the thickness of the protruding rib at the second mating surface.

[0007] The present invention changes the thickness of the first mating surface and the second mating surface by arranging the protruding ribs, thereby changing the tightness during the rotation of the turn buckle, and the method is simple and controllable.

[0008] Furthermore, the thickness of the protruding rib formed on the second mating surface decreases gradually from close to the first mating surface to far away from the first mating surface.

[0009] In this way, the turn buckle can be smoothly rotated on the back of the turn buckle fitting part body, avoiding the jamming of the rotation process caused by the uneven back of the turn buckle fitting part body.

[0010] Furthermore, the number of the protruding ribs is two, and the protruding ribs are symmetrically distributed in an arc shape on a side of the turn-lock fitting part body away from the turn-lock.

[0011] In this way, the protruding ribs are symmetrically arranged on the back of the main body of the screw-on fitting part, and the method is simple.

[0012] Furthermore, the thickness of the protruding rib gradually decreases from both ends to the middle portion of the protruding rib.

[0013] In this way, the portion of the protruding rib that cooperates with the buckle forms a first matching surface and a second matching surface, and the thickness of the protruding rib changes smoothly, thereby improving the smoothness of the rotation of the buckle.

[0014] Furthermore, the buckle includes a buckle body and a buckle, the buckle is arranged on the side of the buckle body away from the buckle, and a buckle hole is provided on the buckle matching part body, the buckle is suitable for being inserted into the buckle hole and abutting against the side of the buckle matching part body away from the buckle through the buckle hole.

[0015] In this way, the rotatable connection between the turn buckle and the turn buckle matching part is achieved in a simple manner.

[0016] Furthermore, the screw-on fitting portion further comprises a supporting portion, the supporting portion is located in the clamping hole and is coaxially arranged with the clamping hole, and a rotating groove suitable for the buckle to rotate is formed between the outer wall of the supporting portion and the inner wall of the clamping hole.

[0017] In this way, the buckle is suitable for rotating in the rotating groove, and the connecting portion abuts against the supporting portion to limit the further movement of the turn buckle toward the turn buckle matching portion, thereby achieving the rotational matching between the turn buckle and the turn buckle matching portion.

[0018] Furthermore, the screw-on fitting portion further includes a limiting portion, one end of which is connected to the outer wall of the supporting portion, and the other end of which is connected to the inner wall of the clamping hole.

[0019] In this way, the rotation of the buckle on the back of the twist-fit portion can be limited.

[0020] Furthermore, the limiting portion includes a first limiting rib and a second limiting rib, and a line connecting the first limiting rib and the second limiting rib intersects with a central axis of the clamping hole.

[0021] In this way, by dividing the rotating groove into the first rotating groove and the second rotating groove, the rotating range of the turn buckle is limited, so that the turn buckle can achieve the purpose of fixing and releasing only by rotating within a certain range.

[0022] Furthermore, a middle groove is provided on a side of the support portion away from the rotary buckle, and the middle groove is coaxially arranged with the clamping hole.

[0023] The setting of the middle groove makes it easy to evenly set the wall thickness of the side wall of the support part to ensure that the injection molding does not shrink.

[0024] Furthermore, the turn-lock fitting part also includes a limiting structure, which is arranged on a side of the turn-lock fitting part body facing the turn buckle, and when the turn buckle is rotationally engaged with the turn-lock fitting part, the limiting structure is suitable for limiting the rotation of the turn buckle along a predetermined path.

[0025] This improves the stability of the turnbuckle rotation process.

[0026] Furthermore, a notch is also provided on the body of the screw-on fitting portion, the opening of the notch faces the clamping hole and the notch is connected to the clamping hole, the notch is suitable for the clamp to be clamped in, and the number of the notches is consistent with the number of the clamps.

[0027] This helps the buckle to be inserted into the buckle hole, and the buckle body is not easily deformed.

[0028] Furthermore, the number of the buckles is at least two, and at least two of the buckles are located on the same circumference of the buckle body on a side away from the buckle.

[0029] In this way, at least two buckles cooperate with the back of the turn buckle fitting part body, which helps to improve the stability of the turn buckle rotation process.

[0030] Furthermore, there are two buckles, and the two buckles are located at two radial ends of the same circle. When the buckles are matched with the clamping hole, the center line of the two buckles intersects with the central axis of the clamping hole.

[0031] In this way, the provision of two buckles can not only ensure the engagement between the buckle and the buckle mating portion, but also avoid assembly difficulties caused by the difficulty in ensuring the strength of the plastic assembly due to too many buckles.

[0032] Furthermore, the turn buckle also includes a connecting portion, which is arranged between the buckle and the turn buckle body and connects the buckle and the turn buckle body.

[0033] In this way, the strength of the buckle is increased, and the overall stability of the buckle and the main body of the screw-on fitting part is improved.

[0034] Furthermore, a receiving groove is provided on a wall surface of the connecting portion connected to the buckle, and when the buckle is rotationally engaged with the buckle engaging portion, the receiving groove is suitable for accommodating at least a portion of the supporting portion.

[0035] In this way, when the turn buckle is matched with the turn buckle matching portion, the support portion is at least partially accommodated in the accommodating groove, thereby reducing the height of the buckle body to improve the strength of the buckle.

[0036] Further, the turn button body includes a first end and a second end, the first end is suitable for being rotatably connected to the turn button fitting portion, and a size of the first end is larger than a size of the second end.

[0037] This makes it easier for the user to operate the turn buckle.

[0038] Furthermore, a protrusion is provided on a side of the second end facing the screw-on fitting portion.

[0039] This makes it easier for users to rotate the knob, improving operational convenience.

[0040] Furthermore, an anti-slip portion is provided on a side of the turn buckle body away from the turn buckle fitting portion.

[0041] This helps to increase the friction between the user's hand and the turn buckle body, making it easier for the user to turn the turn buckle.

[0042] The present invention further provides a shell assembly, comprising a shell and a turn-buckle structure as described in any one of the above items, wherein the turn-buckle structure is installed on the shell, and the turn-buckle structure is suitable for installing a part to be fixed on the shell.

[0043] Furthermore, the part to be fixed includes a filter.

[0044] The present invention also provides an air conditioner, comprising the housing assembly as described above.

[0045] The beneficial effects of the housing assembly and the air conditioner provided by the present invention compared with the prior art are the same as the beneficial effects of the filter rotary buckle structure compared with the prior art, which will not be repeated here.

[0063] 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.

[0064] In addition, the above, below, left, right, front, and back mentioned in the embodiments of the present invention refer to the housing 1 of the present invention being in an adjacent position. Figure 1 The placement position in is the corresponding position of the entire housing 1; wherein, X positive represents "front", X reverse represents "back", Y positive represents "right", Y reverse represents "left", Z positive represents "up", and Z reverse represents "down".

[0065] See also Figure 1-5 As shown, an embodiment of the present invention provides a turn button 1 structure, which is suitable for installing a part to be fixed on a fixed object. The part to be fixed includes a mesh part such as a filter screen, and the fixed object includes a housing, a panel, etc. The turn button 1 structure includes a turn button 1 and a turn button matching part 2. The back of the turn button matching part 2 is formed with a matching surface 20 suitable for rotating with the turn button 1. The matching surface 20 includes a first matching surface 201 and a second matching surface 202. The first matching surface 201 is protruding from the second matching surface 202. The so-called back refers to Figure 1 As shown in the rear side, for the turn buckle 1, the side of the turn buckle 1 facing the turn buckle fitting part 2 is the back side, and the opposite side is the front side of the turn buckle 1. For the turn buckle fitting part 2, the side of the turn buckle fitting part 2 facing the turn buckle 1 is the front side, and the side of the turn buckle fitting part 2 facing away from the turn buckle 1 is the back side of the turn buckle fitting part 2.

[0066] In this embodiment, the turn button fitting part 2 is installed on the fixed object, and the turn button 1 is rotatably connected to the turn button fitting part 2. When installing, the turn button 1 is rotated so that the turn button 1 abuts against the surface of the part to be fixed, so that the part to be fixed can be fixed. When the part to be fixed is disassembled, the turn button 1 is rotated so that the turn button 1 is rotated away from the part to be fixed, so that the part to be fixed can be removed. In this embodiment, the part to be fixed is installed on the fixed object, or the part to be fixed is released from the fixed object through the rotational cooperation between the turn button 1 and the turn button fitting part 2. The disassembly and assembly method is simple, and the rotation fixing method saves time and effort. The part to be fixed is not easy to bend and deform, which increases the service life of the part to be fixed.

[0067] In addition, since the first mating surface 201 is protruding from the second mating surface 202, there is a thickness difference between the first mating surface 201 and the second mating surface 202. The so-called thickness refers to Figure 1 When the turn button 1 is matched with the first matching surface 201, the turn button 1 is in the first position or the second position. At this time, the force to be overcome when the turn button 1 is matched with the first matching surface 201 is large, the force required to rotate the turn button 1 is large, and the turn button 1 feels tight when rotating. Fig.11 ,12 As shown, the turn button 1 is suitable for installing the fixed part on the fixed object. When the turn button 1 is in the second position, as shown in FIG. Fig. 9 , 10 As shown, the turn buckle 1 releases the fixed part from the fixed object. When the buckle 12 is matched with the second matching surface 202, as shown in FIG. Fig.13 As shown, the turn buckle 1 is in a rotation process from the first position to the second position or from the second position to the first position. At this time, the force that needs to be overcome when the turn buckle 1 cooperates with the second mating surface 202 is small, the force required to rotate the turn buckle 1 is small, and the turn buckle 1 feels loose when rotating.

[0068] In one embodiment, Figure 3 , 4 As shown, the turn-on fitting part 2 includes a turn-on fitting part body 21 and a protruding rib 27. The protruding rib 27 is arranged on the back of the turn-on fitting part body 21 and forms a first mating surface 201 and a second mating surface 202 on the back of the turn-on fitting part body 21 respectively. The thickness of the protruding rib 27 at the first mating surface 201 is greater than the thickness of the protruding rib 27 at the second mating surface 202.

[0069] By setting a protruding rib 27 on the back of the turn-lock mating part body 21, the thickness of the first mating surface 201 and the second mating surface 202 can be changed, thereby changing the tightness of the turn-lock 1 during rotation. This setting method is simple, and the thickness difference between the first mating surface 201 and the second mating surface 202 can be controlled by changing the thickness of the protruding rib 27, and it has strong controllability.

[0070] Preferably, the thickness of the protruding rib 27 formed on the second mating surface 202 decreases gradually from close to the first mating surface 201 to far away from the first mating surface 201. In this way, the turn buckle 1 can rotate smoothly on the back of the turn buckle fitting body 21, avoiding the rotation process jamming caused by the uneven back of the turn buckle fitting body 21.

[0071] like Figure 6-8 As shown, the turn buckle 1 includes a turn buckle body 11 and a buckle 12. The buckle 12 is arranged on the back of the turn buckle body 11 and is suitable for matching with the turn buckle matching part 2. The turn buckle matching part body 21 is provided with a clamping hole 22. The central axis of the clamping hole 22 is consistent with the central line of the turn buckle matching part body 21. The buckle 12 is suitable for being inserted into the clamping hole 22 and abutting against the back of the turn buckle matching part body 21 through the clamping hole 22. In this way, the buckle 12 is clamped with the clamping hole 22, so that the turn buckle 1 and the turn buckle matching part 2 are rotatably connected.

[0072] The number of buckles 12 is at least two, and at least two buckles 12 are located on the same circumference of the back of the buckle body 11. Figure 7As shown, there are two buckles 12, and the two buckles 12 are located at the two ends of the same radial direction. When the buckles 12 are matched with the clamping hole 22, the center line of the two buckles 12 intersects with the central axis of the clamping hole 22. Providing two buckles 12 can not only ensure the clamping connection between the turn buckle 1 and the turn buckle matching part 2, but also avoid assembly difficulties caused by the difficulty in ensuring the strength of the plastic assembly due to too many buckles 12.

[0073] Furthermore, if Figure 8 As shown, the turn buckle 1 further includes a connecting portion 13, which is disposed between the buckle 12 and the turn buckle body 11 and connects the buckle 12 and the turn buckle body 11. The arrangement of the connecting portion 13 helps to increase the strength of the buckle 12 and improve the overall stability of the buckle 12 and the turn buckle mating portion body 21.

[0074] Furthermore, if Figure 2 As shown, the screw-on fitting portion 2 further includes a support portion 23, which is located in the clamping hole 22 and is coaxially arranged with the clamping hole 22. A rotation groove 24 suitable for the buckle 12 to rotate is formed between the outer wall of the support portion 23 and the inner wall of the clamping hole 22. Figure 8 As shown, the buckle 12 includes a buckle body 121 and a hook 122, one end of the buckle body 121 is connected to the connecting portion 13, and the other end of the buckle body 121 is connected to the hook 122. In this way, when the turn button 1 and the turn button matching portion 2 are rotated and matched, the hook 122 passes through the rotation groove 24 and the side of the hook 122 facing the connecting portion 13 abuts against the back of the turn button matching portion body 21, the buckle body 121 rotates in the rotation groove 24, and the connecting portion 13 abuts against the support portion 23 to limit the turn button 1 from moving further toward the turn button matching portion 2, so that the turn button 1 and the turn button matching portion 2 are rotated and matched.

[0075] Furthermore, if Figure 7 As shown, a receiving groove 14 is provided on the wall surface of the connecting portion 13 connected to the buckle 12, and the receiving groove 14 is suitable for receiving at least part of the supporting portion 23. Thus, when the turn buckle 1 is matched with the turn buckle matching portion 2, the supporting portion 23 is at least partly received in the receiving groove 14, thereby reducing the height of the buckle body 121 to improve the strength of the buckle 12. The height of the buckle body 121 refers to the distance between the two ends of the buckle body 121.

[0076] Furthermore, if Figure 2 , 3As shown, the screw-on fitting part 2 also includes a limiting part 28, one end of which is connected to the outer wall of the support part 23, and the other end of which is connected to the inner wall of the clamping hole 22. The limiting part 28 is used to limit the rotation of the buckle 12 on the back of the screw-on fitting part 2. In one embodiment, the limiting part 28 includes a first limiting rib 281 and a second limiting rib 282, and the connecting line between the first limiting rib 281 and the second limiting rib 282 intersects with the central axis of the clamping hole 22, that is, the first limiting rib 281 and the second limiting rib 282 are in the radial direction of the same circumference, so that the rotation groove 24 is divided into a first rotation groove 241 and a second rotation groove 242. The buckle body 121 rotates in the first rotation groove 241 and the second rotation groove 242 respectively, and stops rotating under the limiting action of the first limiting rib 281 and the second limiting rib 282.

[0077] In a specific embodiment, there are two buckles 12, which are respectively a first buckle 123 and a second buckle 124 for the sake of convenience. The first buckle 123 includes a first buckle body and a first hook, and the second buckle 124 includes a second buckle body and a second hook. Fig. 9 The state in counterclockwise rotation to Fig.11 In the state of the first buckle body 121 rotating in the first rotation groove 241, the second buckle body 121 rotating in the second rotation groove 242, the first limiting rib 281 restricts the first hook 122 from continuing to rotate counterclockwise, and the second limiting rib 282 restricts the second hook 122 from continuing to rotate counterclockwise. The rotation direction mentioned here refers to the clockwise and reverse directions when looking at the front of the buckle 1, that is, Fig. 9 The arrow direction shown in is counterclockwise. It should be understood that the first hook 122 and the second hook 122 are arranged in a manner similar to the embodiment of the present invention. Fig.10 and 12 Rotates clockwise in the state shown in .

[0078] Preferably, the number of the protruding ribs 27 is two, and the protruding ribs 27 are symmetrically distributed on the back of the turn-lock fitting body 21 in an arc shape, and the two protruding ribs 27 are located on both sides of the line between the first limiting rib 281 and the second limiting rib 282. The protruding rib 27 starts at the position corresponding to the first limiting rib 281 on the back of the turn-lock fitting body 21, and ends at the position corresponding to the second limiting rib 282 on the back of the turn-lock fitting body 21. For the convenience of description, the position corresponding to the first limiting rib 281 on the back of the turn-lock fitting body 21 is called the starting position, and the position corresponding to the second limiting rib 282 on the back of the turn-lock fitting body 21 is called the ending position. One of the two protruding ribs 27 extends from the starting position to the ending position in the clockwise direction along the circumference, and the other of the two protruding ribs 27 extends from the starting position to the ending position in the counterclockwise direction along the circumference. Of course, the number of the protruding rib 27 can also be one, in which case a circle of ribs is provided on the back of the turn-lock fitting part 2.

[0079] like Figure 4 As shown, the thickness of the protruding rib 27 gradually decreases from the two ends to the middle part of the protruding rib 27. That is, the thickness of the middle part of the protruding rib 27 is less than the thickness of the two ends of the protruding rib 27. In this way, from one end to the other end of the protruding rib 27, the thickness of the protruding rib 27 changes from high to low and then to high. The so-called thickness of the protruding rib 27 refers to the thickness of the protruding rib 27 protruding from the back of the main body 21 of the screw-on fitting part. The areas where the two ends of the protruding rib 27 cooperate with the hook 122 form a first mating surface 201, and the areas on the protruding rib 27 with a thickness lower than the thickness of the two ends of the protruding rib 27 form a second mating surface 202. In a specific embodiment, the thickness of the first mating surface 201 is 0.5 mm. From the first mating surface 201 to the second mating surface 202, the thickness of the protruding rib 27 gradually decreases to 0, that is, the thickness of the protruding rib 27 transitions from 0.5 mm to 0 from one end to the other end, and then from 0 to 0.5 mm. When the buckle 12 is matched with the first matching surface 201, the turn buckle 1 is in the first position or the second position, and the turn buckle 1 and the turn buckle matching part 2 are in a tightened state, which increases the force of the turn buckle 1 on the fixed part to be fixed firmly, or after the fixed part is released, the turn buckle 1 is not easy to rotate automatically. When the buckle 12 is matched with the second matching surface 202, the turn buckle 1 is in a rotation process from the first position to the second position or from the second position to the first position, and the turn buckle 1 and the turn buckle matching part 2 are in a loosened state, making the turn buckle 1 easier to rotate, saving time and effort.

[0080] Furthermore, if Figure 2As shown, a notch 25 is also provided on the body 21 of the screw-on fitting part. The opening of the notch 25 faces the clamping hole 22 and the notch 25 is connected with the clamping hole 22. The notch 25 is suitable for the clamping of the buckle 12, and the number of the notches 25 is consistent with the number of the buckles 12. In the prior art, the rotational clamping method of the buckle 12 and the clamping hole 22 is generally that when the buckle 12 is inserted into the clamping hole 22, the buckle 12 is squeezed by the inner wall of the clamping hole 22 and moves toward each other. After the buckle 12 passes through the clamping hole 22, the buckle 12 returns to the initial position, thereby realizing the connection between the buckle 12 and the clamping hole 22. However, in this way, the buckle 12 needs to be squeezed and deformed. After long-term use, the strength of the clamping of the buckle 12 and the clamping hole 22 is reduced. The provision of the notch 25 in this embodiment helps the buckle 12 to be clamped into the clamping hole 22, and the buckle body 121 is not easy to deform.

[0081] As shown in the figure, the buckle 12 is inserted into the clamping hole 22 through the notch 25. At this time, the buckle 1 is in a horizontal state. The buckle 1 is rotated 90° counterclockwise and is in a vertical state. During the rotation of the buckle 1, the hook 122 abuts against the protruding rib 27, and as the buckle 12 rotates, the abutting force between the hook 122 and the protruding rib 27 changes from large to small and then to large. Therefore, when the buckle 1 is in the horizontal and vertical states, the hand feels tighter, and the buckle 1 feels looser during the rotation.

[0082] Furthermore, if Figure 3 As shown, the back of the support portion 23 is provided with a middle groove 29, and the middle groove 29 is coaxially arranged with the clamping hole 22. In this way, the wall thickness of the side wall of the support portion 23 can be uniform, ensuring that the injection molding does not shrink.

[0083] Furthermore, the turn-lock fitting part 2 further includes a limiting structure 26, which is disposed on the front surface of the turn-lock fitting part body 21. When the turn-lock 1 and the turn-lock fitting part 2 rotate and fit, the limiting structure 26 is adapted to limit the turn-lock 1 from rotating along a predetermined path, thereby improving the stability of the turn-lock 1 during rotation. As shown in the figure, the limiting structure 26 is an arc-shaped rib, and the curvature of the arc-shaped rib matches the outer edge of the second end 112.

[0084] Furthermore, if Figure 6As shown, the turn button body 11 includes a first end 111 and a second end 112, the first end 111 is suitable for being rotatably connected with the turn button matching part 2, and the second end 112 is suitable for bearing the applied force to realize the rotation of the turn button 1, and the size of the first end 111 is larger than the size of the second end 112, so that the turn button body 11 is in a shape with one end larger and the other end smaller. This is convenient for users to distinguish and also convenient for users to rotate the second end 112.
