Description

Technical Field

[0001] This invention belongs to the field of external connection technology and relates to an external component. The external component acts on a partition, which has at least two parallel inclined surfaces that intersect with the partition surface and are fixed to the partition. A connecting channel is left between two adjacent parallel inclined surfaces to connect the spaces on the inside and outside of the partition surface. As a special case, the partition is an air conditioner air outlet guide plate. Background Technology

[0002] Air conditioners are widely used indoor temperature control appliances. Indoor air is drawn into the air conditioner for cooling or heating before being circulated back into the room. For larger indoor spaces, such as shopping malls, conference rooms, and large office areas, high-power central air conditioning systems are typically used to achieve better cooling or heating effects. These central air conditioning systems have multiple air outlets that supply air into the room. These air outlets are generally equipped with air deflectors. However, some consumers feel that the air outlets have a single airflow angle and that the airflow is too concentrated, which may lead to health problems caused by direct airflow. Therefore, it is necessary to add air deflectors to the air outlets.

[0003] Existing air guiding mechanisms typically use hooks to attach to the air guide plate of the air conditioner vent. The hooks need to be inserted into the inside of the air guide plate and a suitable hooking point needs to be found. The presence of air guide vanes in the air guide plate causes considerable trouble for the above work. Summary of the Invention

[0004] Given the structure of the air vent guide plate of an air conditioner, this invention provides an external connector that acts on a partition. The partition surface of the partition has at least two parallel inclined surfaces that intersect with the partition surface and are fixed relative to the partition. A connecting channel is left between two adjacent parallel inclined surfaces to connect the inner and outer spaces of the partition surface. Along a direction perpendicular to the partition surface, the inclined surface located above the connecting channel is designated as the upper inclined surface, and the inclined surface located below the connecting channel is designated as the lower inclined surface. The end of the lower inclined surface at the bottom of the connecting channel is designated as the bottom end of the lower inclined surface, and the end of the upper inclined surface at the top of the connecting channel is designated as the top end of the upper inclined surface. Similar to the background art, the structure of the partition makes it difficult to use a hook to reach into the partition and hook it. On the one hand, the width of the connecting channel and the angle between the two adjacent parallel inclined surfaces and the partition surface may prevent the hand holding the hook from entering the connecting channel to insert the hook into the partition. On the other hand, the upper and lower inclined surfaces are often made of solid, non-transparent material, which may obstruct the view and make it difficult to find the part for the hook to be hooked. Therefore, the external connector of this invention completely abandons the solution of using hooks to fix it inside the partition. Instead, it includes a functional side extending into the connecting channel. When the projection of the bottom end of the lower inclined surface on the plane of the upper inclined surface along a direction perpendicular to the two adjacent parallel inclined surfaces is below the top end of the upper inclined surface, the functional side includes a first end for abutting the lower inclined surface, a second end for abutting the upper inclined surface, a main segment connecting the first end and the second end, and an external end for attaching a weight or an external force-applying object. When the projection of the bottom end of the lower inclined surface on the plane of the upper inclined surface along a direction perpendicular to the two adjacent parallel inclined surfaces is below the top end of the upper inclined surface... When positioned above, the action edge includes a first end for abutting the lower inclined plane, a second end for abutting the top of the upper inclined plane, a main segment of the action edge connecting the first end and the second end, and an external end for attaching a weight or applying external tension. The length of the main segment of the action edge is greater than the distance between two adjacent parallel inclined planes. When an external force is applied to the action edge through the external end, the second end rotates around the first end toward the bottom of the connecting channel and is blocked by the upper inclined plane or the top of the upper inclined plane, thus being able to withstand the tension of the external end. Typically, the external end is directly connected to the second end or the action edge, but some external ends are indirectly connected to the second end or the main segment of the action edge.

[0005] Users can choose the fixing position of the first end themselves, such as directly choosing the bottom end of the lower slope or a position near the bottom end of the lower slope, which makes it convenient for hand operation. In addition, the fixing position of the first end is not blocked by the slope and is visible to the naked eye. Unlike the prior art, there is no need to find a place for the hook to be hooked. Therefore, the external component described in this invention can greatly facilitate the installation or removal on the partition.

[0076] This section provides a detailed description of the invention.

[0077] As described in the background section, current air guide vanes used as air conditioner vents have a fixed and concentrated airflow direction, requiring additional air guiding mechanisms to disperse or change the airflow direction. These air guiding mechanisms typically use hooks to attach to the inner side of the air guide vane; however, due to the vane's structure, this operation is difficult for the user. This invention discovers that structures similar to air guide vanes are usually partitions separating the inner and outer sides, such as... Figure 1As shown, the partition has at least two parallel inclined surfaces intersecting the partition surface 1. Generally, the at least two parallel inclined surfaces are fixed relative to the partition. If the at least two parallel inclined surfaces can rotate relative to the partition, but can also stop rotating relative to the partition, and can still stably maintain the state of stopping rotating relative to the partition under a certain external force, then the at least two parallel inclined surfaces should also be considered as fixed relative to the partition. The angle between the at least two parallel inclined surfaces and the partition surface can generally be greater than zero degrees and less than or equal to ninety degrees. Such adjacent parallel inclined surfaces leave a connecting channel 4 between the inner and outer sides of the partition surface. Along the direction perpendicular to the partition surface 1, among the two adjacent parallel inclined surfaces, the inclined surface located above the connecting channel 4 is the upper inclined surface 2, and the inclined surface located below the connecting channel 4 is the lower inclined surface 3. The end of the lower inclined surface 3 at the bottom of the connecting channel is the bottom end 6 of the lower inclined surface, and the end of the upper inclined surface 2 at the top of the connecting channel 4 is the top end 5 of the upper inclined surface. Generally speaking, the partitions are divided into two types, the first type being as follows: Figure 2 As shown, in this type of partition, the projection of the bottom end 6 of the lower slope onto the upper slope is 7 below the top end 8 of the upper slope. The second type is as follows... Figure 3 As shown, in this type of partition, the projection of the bottom end 9 of the lower slope onto the upper slope is 10 above the top end 11 of the upper slope. Therefore, the present invention provides two external fittings, see... Figure 4 For the first type of partition, the external connector includes a functional side extending into the connecting channel 4. This functional side includes a first end 12 for abutting the lower inclined surface 3, a second end 15 for abutting the upper inclined surface 2, a main functional side segment 13 connecting the first end 12 and the second end 15, and an external end 14. The length of the main functional side segment 13 is greater than the distance between the upper inclined surface 2 and the lower inclined surface 3. Of course, the external end 14 is oriented outwards... Figure 4 Since the direction of gravity is the same as the direction of the load, a heavy object can be connected to the outer end 14. More commonly, the outer end 14 is connected in a direction different from the direction of gravity. In this case, a force-applying object can be used instead of a heavy object, with the force applied in the same direction as the outer end 14. After the outer end 14 is subjected to force, the second end 15 rotates around the first end 12 in the direction of the force applied to the outer end 14. Because the length of the main segment 13 is greater than the distance between the upper inclined surface 2 and the lower inclined surface 3, the upper inclined surface 3 prevents the second end 15 from rotating around the first end 12, allowing the outer end 14 to withstand external tension or external gravity. See [link / reference]. Figure 5For the second type of partition, the external component includes an action side extending into the connecting channel. The action side includes a first end 16 for abutting against the lower slope, a second end 18 for abutting against the top of the upper slope 11, a main action side segment 17 connecting the first end 16 and the second end 18, and an external end 19. The length of the main action side segment 17 is greater than the distance between the upper slope and the lower slope. After the external end 19 is subjected to force, the second end 18 rotates around the first end 16 in the direction of the force applied to the external end 19. The top of the upper slope 11 blocks the rotation of the second end 18 around the first end 16, so that the external end 19 can withstand external tension or external gravity.

[0078] For most external connectors, the external end is equipped with an external interface, such as a universal interface, to facilitate the connection of heavy objects or objects subject to tension, thereby adapting to various external structures and meeting the needs of connecting the partition to various other structures. Of course, in a few external connectors, the external end and the external structure can also be made as an integral structure. Obviously, compared with the prior art, the process of using the external connector of the present invention is quite simple. The entire operation is carried out within the connecting channel. To facilitate manual operation, the first end can be further placed against or near the bottom of the lower slope.

[0079] During the rotation of the second end around the first end, the first end remains fixed relative to the lower inclined plane, ensuring that the first end does not slip relative to the external end when force is applied. (See...) Figure 6 In some external components, the lower inclined surface 3 of the partition 1 has an extension section 25 extending into the connecting channel 4. The extension section 25 can form a retaining groove with the lower inclined surface 3 for the first end 26 to abut against, ensuring that the first end 26 is always in the retaining groove when the external end 27 is under force. However, in most cases, there is no similar... Figure 6 The abutment groove shown in the invention, in part, is provided by setting the first end as an end face, which fits against at least a portion of the lower inclined surface. On one hand, the end face design increases the contact area between the first end and the lower inclined surface; on the other hand, when the external end is under force, the end face design reduces the pressure exerted by the first end on a unit area of ​​the lower inclined surface that abuts against the first end, thereby increasing the maximum force on the external end. Further, as... Figure 7 As shown, a portion of the end face 22 is provided with an external anti-slip layer 23 and / or an external adhesive layer 24 to prevent relative sliding between the end face and the lower inclined surface 20 due to the force exerted on the external end. In addition, in order to accommodate at least two parallel inclined surfaces that intersect the partition surface at different angles, the end face 22 is rotatably connected to the main segment 21 of the action side. This ensures that the end face and the lower inclined surface that intersect the partition surface at different angles are completely fitted together, further maximizing the contact area between the first end and the lower inclined surface.

[0080] like Figure 8Other solutions involve adding a telescopic section 30 to the first end 29, extending downwards towards the bottom of the downward-sloping surface 28. This telescopic section 30 has a clamping groove 31 to hold the bottom of the downward-sloping surface, allowing the first end 29 to be fixed to the downward-sloping surface 28. Alternatively, a telescopic section extending downwards towards the top of the downward-sloping surface can be added to the first end, with a clamping groove to hold the top of the downward-sloping surface, allowing the first end to be fixed to the downward-sloping surface. Some solutions also employ different technical means for the two types of partitions, such as... Figure 9 For the first type of partition, the first end 29 includes a telescopic section 30 that extends and retracts towards the top of the downward inclined surface 28. The telescopic section 30 is provided with a stop block 32 that passes through the plane of the downward inclined surface 28 and blocks the top of the downward inclined surface. When the external end is subjected to force, the stop block 32 can prevent the first end 28 from sliding towards the bottom of the downward inclined surface 28. For the second type of partition, the first end includes a telescopic section that extends and retracts towards the bottom of the downward inclined surface. The telescopic section is provided with a stop block that passes through the plane of the downward inclined surface and blocks the bottom of the downward inclined surface. When the external end is subjected to force, the stop block can prevent the first end from sliding towards the top of the downward inclined surface.

[0081] For the second end, no improvement is usually required. However, for the first type of partition, some external components still use an end face design for the second end, where the second end is an end face that fits against at least part of the upper inclined surface. On the one hand, the end face design increases the contact area between the second end and the upper inclined surface. On the other hand, when the external end is under force, the end face design reduces the pressure exerted by the second end on the unit area of ​​the upper inclined surface that abuts against the second end, thereby increasing the maximum force on the external end. Furthermore, some end faces are provided with an external anti-slip layer and / or an external adhesive layer to prevent relative sliding between the end face and the upper inclined surface due to the force on the external end when the end face abuts against the upper inclined surface. In addition, to accommodate at least two parallel inclined surfaces that intersect the partition surface at different angles, the end face is rotatably connected to the main segment of the action side. This ensures that the end face and the upper inclined surfaces that intersect the partition surface at different angles are fully fitted, further maximizing the contact area between the second end and the upper inclined surface. For the second type of partition, the second end of some external components is provided with a stop block that abuts against the top of the upper inclined surface. When the external end is subjected to force, the stop block can prevent the second end from rotating around the first end in the direction of the force applied to the external end.

[0082] The external end can be directly or indirectly connected to the main segment of the action side. As a special case, the external end and the main segment of the action side are an integral structure. More commonly, the external end is directly connected to the main segment of the action side. In some external components, part of the main segment of the action side is provided with a slide rail for the end of the external end to slide on the action side, changing the position of the external end relative to the main segment of the action side. This is quite practical. For example, when the user connects the external weight or external tensioning object to the external end and finds that the position of the external weight or external tensioning object is not appropriate, the position of the external end sliding on the slide rail can be adjusted to make the position of the external weight or external tensioning object optimal. A further improvement is to add a first fastening member to fasten or loosen the end and the slide rail. After the position of the external end sliding on the slide rail is determined, the first fastening member can be used to fasten the end and the slide rail together. Other external components also have similar functions. The external ends of these external components are rotatably connected to the main segment of the action side. When the user finds that the angle between the external weight or the external tensioning object and the main segment of the action side is not right, the external end can be rotated relative to the main segment of the action side to obtain a satisfactory angle. As an example, the external end can even be rotatably connected to a second end. In order to make similar functions more powerful, a better solution is to improve the end of the external end. The improved end of the external end includes a sliding part that slides on the slide rail and a main body part that is rotatably connected around the sliding part. In this way, the position of the external weight or the external tensioning object relative to the main segment of the action side will have a greater degree of freedom.

[0083] For connecting channels of different widths, using the same external connector may not ensure that the length of the main segment of the active side is greater than the distance between two adjacent parallel inclined planes, making the external connector unusable. Therefore, in the external connector described in this invention, part of the main segment of the active side is a telescopic segment, so that it can be applied to partitions with connecting channels of different widths.

[0084] During the use of the external connector, unstable forces on the external end may affect the stability of the working side installed between the upper and lower inclined surfaces, specifically manifested as wobbling, or even the first and second ends sliding off the lower and upper inclined surfaces respectively. The external connector described in this invention also adds a stabilizing structure, wherein the external end is an external vertical rod, and the external connector also includes a stop block and a nut sleeve threadedly connected to the external vertical rod. The stop block has a through hole for the external vertical rod to pass through, and the diameter of the nut sleeve is larger than the diameter of the through hole. By screwing it into the external vertical rod, the stop block abuts against the bottom end of the connecting channel. When the stop block abuts against the bottom end of the connecting channel, the stop block pulls the external vertical rod through the nut sleeve, thereby making the first and second ends firmly abut against the lower and upper inclined surfaces respectively, without wobbling or falling off.

[0085] After the external component is used, it can usually be removed from the connecting channel. However, the present invention further reduces the volume of the external component when it is not in use. For example, in some external components, the main segment of the function side is provided with a space to accommodate part of the external end when the main segment of the function side and the external end rotate and approach each other. In other external components, the external end is provided with a space to accommodate part of the main segment of the function side when the main segment of the function side and the external end rotate and approach each other. The space can accommodate the part of the external end and the main segment of the function side that overlap when they rotate and approach each other, thereby reducing the overall volume of the external component.

[0086] As mentioned above, the external terminal can also be indirectly connected to the main segment of the action side. The following describes the external connector that indirectly connects the external terminal to the main segment of the action side.

[0087] See Figure 13 The external components listed in this invention also include a horizontal edge 49 and a pull edge 48. The main functional segment 47, the horizontal edge 49, and the pull edge 48 are interconnected to form an external triangle, creating a more stable structure. The external end 50 is connected to the horizontal edge 49. Specifically, the main functional segment 47, the horizontal edge 49, and the pull edge 48 can be interconnected by rotation or sliding to adjust the shape of the external triangle, so that the adjusted external triangle satisfies, for example, keeping the force direction of the horizontal edge 49 and the external end 50 perpendicular to each other or making the external end reach a specific position, etc.

[0088] Specifically, in some external components, one end of the horizontal edge is rotatably or slidably connected to a portion of the functional edge on one side of the first end. When one end of the horizontal edge is slidably connected to a portion of the functional edge on one side of the first end, the main segment of the portion of the functional edge on one side of the first end is provided with a slide rail. Through the slide rail, the main segment of the portion of the functional edge on one side of the first end is slidably connected to the end of the horizontal edge.

[0089] In some external components, the other end of the horizontal edge is rotatably or slidably connected to the other end of the pull edge. When the other end of the horizontal edge is slidably connected to the other end of the pull edge, the other end of the horizontal edge is provided with a slide rail, through which the other end of the horizontal edge is slidably connected to the end of the pull edge; or, the pull edge is provided with a slide rail, through which the pull edge is slidably connected to the end of the other end of the horizontal edge.

[0090] In some external components, the other end of the pull edge is rotatably or slidably connected to the main section of the partial functional edge on one side of the second end. When the other end of the pull edge is slidably connected to the main section of the partial functional edge on one side of the second end, the main section of the partial functional edge on one side of the second end is provided with a slide rail. Through the slide rail, the main section of the partial functional edge on one side of the second end is slidably connected to the end of the other end of the pull edge.

[0091] The connection between the external end and the horizontal edge can also be a rotating connection or a sliding connection. In some external components, the horizontal edge is provided with a slide rail for the end of the external end to slide on the working edge, changing the position of the external end relative to the horizontal edge. This is quite practical. For example, when the user connects the external weight or external tensioning object to the external end and finds that the position of the external weight or external tensioning object is not appropriate, the position of the external end sliding on the slide rail can be adjusted to make the position of the external weight or external tensioning object optimal. A further improvement is to add a fastening element to fasten or loosen the end and the slide rail. After the position of the external end sliding on the slide rail is determined, the fastening element can be used to fasten the end and the slide rail together. Other external components also have similar functions. The external ends of these components are rotatably connected to the horizontal edge. When the user finds that the angle between the external weight or the external tensioning object and the main segment of the working edge is not right, the external end can be rotated relative to the horizontal edge to obtain a satisfactory angle. To make similar functions more powerful, a better solution is to improve the end of the external end. The improved end of the external end includes a sliding part that slides on the slide rail and a main body part that rotates around the sliding part. In this way, the position of the external weight or the external tensioning object relative to the horizontal edge will have a greater degree of freedom.

[0092] Similarly, in some external components, the parts where the horizontal edge, the pull edge, and the main segment of the action edge are slidably connected to each other are also equipped with the function of mutual rotation, so that the specific shape of the external triangle formed by the horizontal edge, the pull edge, and the main segment of the action edge can be arbitrarily adjusted. Specifically, the end that slides on the slide rail is at least divided into a sliding part that slides on the slide rail and a main body part that rotates and connects around the sliding part.

[0093] Furthermore, some external components also include a first tensioning member that fastens or loosens the end to the slide rail. Once the position of the end sliding on the slide rail is determined, the first tensioning member can be used to fasten the end to the slide rail.

[0094] Any existing structure that can position the end on the slide rail can be used as the first tensioning element described in this invention. To facilitate rapid implementation by technicians, this invention lists two types of first tensioning elements. The first type includes a tensioning post passing through the slide rail and the end, and two clamping blocks disposed at both ends of the tensioning post for clamping the slide rail and the end, respectively. At least one clamping block is threadedly connected to the tensioning post to control the distance between the two clamping blocks, thereby tightening or loosening the slide rail and the end. See [link to relevant documentation]. Figure 10The second type of first tensioning component includes a tensioning post 33 threadedly connected to the end 37. One end of the tensioning post 33 passes through the end 37 and abuts against the slide rail 36. The tensioning post 33 is used to widen the gap 34 between the slide rail 36 and the end 37. A portion of the end is provided with a stop surface 35 that abuts against the slide rail 36. When the tensioning post 33 is tightened, the portion of the end abuts against the slide rail 36 through the stop surface 35, preventing the end 37 from moving relative to the slide rail 36.

[0095] For connecting channels of varying widths, using the same external connector may not ensure that the length of the main segment of the active side is greater than the distance between two adjacent parallel inclined planes, rendering the external connector unusable. Therefore, in the external connector described in this invention, in addition to a portion of the main segment of the active side being a telescopic segment, a portion of the horizontal side is also a telescopic segment. This telescopic portion of the horizontal side can increase the length of the horizontal side, increasing the sliding range of the external connector on the horizontal side. Furthermore, the telescopic portion of the horizontal side can also shorten the length of the horizontal side, even to a length less than the width of the connecting channel, thus allowing it to be completely placed within the connecting channel without being exposed outside. Similarly, a portion of the pull side is a telescopic segment, and this telescopic portion of the pull side further increases the adjustable degree of freedom of the external connector's position.

[0096] Any existing telescopic segment structure can be used as the telescopic segment described in this invention. To facilitate rapid implementation by technicians, this invention provides a first type of telescopic segment, which includes a fixed segment, a movable segment that moves relative to the fixed segment in the telescopic direction of the telescopic segment, and a second tensioning member that fastens or loosens the movable segment and the fixed segment. When a specific length of telescopic segment is required, the movable segment slides on the fixed segment. When the required length is reached, the second tensioning member is fastened. When a telescopic segment of other length is required, the second tensioning member is loosened, and then the second tensioning member is fastened again when the required length is reached.

[0097] Any existing structure that can fasten or loosen the movable segment and the fixed segment can be used as the second fastening element of this invention. To facilitate rapid implementation by technicians, this invention further provides three specific second fastening elements. The first type of second fastening element includes a fastening post passing through the fixed segment and the movable segment, and two clamping blocks disposed at both ends of the fastening post for clamping the fixed segment and the movable segment respectively. At least one clamping block is threadedly connected to the fastening post to control the distance between the two clamping blocks, thereby fastening or loosening the movable segment and the fixed segment. See [link to relevant documentation]. Figure 11The second type of second tightening component includes a tightening post 38 threadedly connected to the movable segment 42. One end of the tightening post 38 passes through the movable segment 42 and abuts against the fixed segment 41. The tightening post 38 is used to widen the gap 39 between the fixed segment 41 and the movable segment 42. Part of the movable segment is provided with a stop surface 40 that abuts against the fixed segment 41. When the tightening post 38 is tightened, the part of the movable segment abuts tightly against the fixed segment 41 through the stop surface 40, preventing the movable segment 42 from moving relative to the fixed segment 41. The third type of second tightening component includes an inner ring sleeve and an outer ring sleeve that is fitted on the inner ring sleeve and threadedly connected to the inner ring sleeve. One end of the inner ring sleeve is fixedly connected to the fixed segment, and the other end is provided with a compression ring fitted on the movable segment. The compression ring has a compression gap. When the outer ring sleeve is tightened towards the inner ring sleeve, the inner surface of the outer ring sleeve compresses the compression ring. By reducing the compression gap, the diameter of the compression ring is reduced, thereby compressing the movable segment and preventing the movable segment from moving relative to the fixed segment.

[0098] To facilitate rapid implementation by technicians, the present invention also provides a second type of telescopic segment, which includes a fixed segment and a movable segment that moves relative to the fixed segment in the telescopic direction. The fixed segment and the movable segment are connected by a spring that extends and retracts in the telescopic direction. Different lengths of telescopic segments can be obtained by applying different external forces to the spring.

[0099] To facilitate rapid implementation by technicians, this invention also provides a third type of telescopic section. The telescopic section includes a fixed segment and a movable segment that moves relative to the fixed segment in the telescopic direction. The movable segment and the fixed segment are connected by threads, and the threading direction of the movable segment and the fixed segment is the same as the telescopic direction of the telescopic section. Those skilled in the art know that a threaded connection refers to a method where a tubular object with internal threads is connected to a cylindrical object with external threads via internal and external threads. This type of telescopic section adjusts its telescopic length by rotating the movable segment relative to the fixed segment. The relative rotation of the movable segment will cause the structure connected to the movable segment to rotate. To avoid rotation of the structure connected to the movable segment, in some embodiments, the movable segment includes a rotating part threadedly connected to the fixed segment and a fixed part stationary relative to the rotating part. The rotating part rotates relative to the fixed part around the axis of the telescopic section. Rotating the rotating part enables the telescopic section to extend or retract, while the fixed part can be connected to other structures of the external component described in this invention without causing those structures to rotate with the movable segment during the telescopic section's extension or retraction. A further improvement is to make the rotating part and the fixed part in this embodiment also threadedly connected. Before the improvement, it was assumed that rotating the rotating part once would lengthen or shorten the telescopic section by one unit. After the improvement, since the rotating part and the fixed part are also threadedly connected, rotating the rotating part once would lengthen or shorten the telescopic section by two units, thus making the adjustment of the length of the telescopic section faster.

[0100] To facilitate rapid implementation by technicians, this invention provides a fourth type of telescopic segment, which includes a fixed segment and a movable segment that moves relative to the fixed segment in the telescopic direction of the telescopic segment. At least two locking positions are provided between the fixed segment and the movable segment to engage the fixed segment and the movable segment in the telescopic direction of the telescopic segment. By selecting different locking positions to engage the fixed segment and the movable segment, telescopic segments with different telescopic lengths can be obtained.

[0101] After use, external components are typically removed from the connecting channel. However, this invention further reduces the volume of the external component when not in use. For example, in some external components, the main segment of the functional side has a receiving space. When the horizontal side and the pull side rotate relative to the functional side and move closer to it, the receiving space can accommodate at least a portion of the horizontal side and / or a portion of the pull side. That is, the receiving space can accommodate the portion where the horizontal side and the main segment of the functional side and / or the pull side overlap with the main segment of the functional side when the horizontal side and the pull side rotate relative to the functional side and move closer to it, thereby reducing the overall volume of the external component. Similarly, in some external components, the horizontal side has a receiving space. When the functional side and the pull side rotate relative to the horizontal side and move closer to it, the receiving space can accommodate at least a portion of the functional side and / or a portion of the pull side. That is, the receiving space can accommodate the portion where the functional side and the pull side overlap with the horizontal side and / or the pull side overlap with the horizontal side when the functional side and the pull side rotate relative to the horizontal side and move closer to it, thereby reducing the overall volume of the external component. For example, in some external components, the pull edge is provided with a receiving space. When the active edge and the horizontal edge rotate relative to the pull edge and approach the pull edge, the receiving space can at least accommodate part of the active edge and / or part of the horizontal edge. That is, the receiving space can accommodate the part where the active edge and the pull edge and / or the horizontal edge and the pull edge overlap when the active edge and the horizontal edge rotate relative to the pull edge and approach the pull edge, thereby reducing the overall volume of the external component.

[0102] For the zipper pull, some external fittings can further reduce the volume when the zipper pull is not in use. These external fittings have folded sections in the zipper pull, see... Figure 12 The entire edge is a folded section, but some edges are only partially folded. Each folded section includes a first segment 45 and a second segment 46, which are rotatably connected. The first segment 45 has a accommodating space. When the folded section is folded, the first segment 45 and the second segment 46 rotate towards each other, and the accommodating space accommodates a portion of the second segment 46. Figure 12 The first segment 45 and the second segment 46 are folded toward the connection point of the active side 44 and the horizontal side 43, or they can be folded away from the connection point of the active side 44 and the horizontal side 43.

[0103] Although some of the external components listed in this invention have an external triangular structure, which can effectively resist unstable external forces that the external end may receive and has considerable stability, those skilled in the art can still refer to the stable structure described in this invention. That is, the external end is an external vertical rod, and the external component also includes a stop block and a nut sleeve that is threadedly connected to the external vertical rod. The stop block has a through hole for the external vertical rod to pass through, and the diameter of the nut sleeve is larger than the diameter of the through hole. By screwing it into the external vertical rod, the stop block abuts against the bottom end of the connecting channel. When the stop block abuts against the bottom end of the connecting channel, the stop block pulls the external vertical rod through the nut sleeve, so that the first end and the second end are respectively firmly abutted against the lower slope and the upper slope, without shaking or falling off.

[0104] The external component described in this invention can be installed in any connecting channel with the partition described in this invention. However, as described in the background section, such partitions are commonly found in air conditioning vent guide plates. Therefore, the preferred application of the external component described in this invention is an air conditioning vent guide plate. Such guide plates have parallel guide vanes that intersect with the plane of the guide plate. The weight or pulling force can be a baffle or a fan to disperse the air conditioning air coming out of the guide plate or change the direction of the air conditioning air coming out.

[0105] This invention also provides a method for installing an external connector. This is partly because incorrect installation methods increase the number of steps involved in installing the external connector described in this invention. For example, if the first end is first inserted into the connecting channel and pressed against the lower slope, and the length of the active side is greater than the width of the connecting channel, then the second end will not be able to be inserted into the connecting channel and pressed against the upper slope. Therefore, the preferred method for installing the external connector includes: a) inserting the second end into the connecting channel; b) firmly pressing the first end against the lower slope; c) pulling the external end or the main segment of the active side so that the second end is firmly blocked by the upper slope. Before step a, the method further includes d) checking whether the length of the main segment of the active side is greater than the width of the connecting channel (i.e., the distance between the upper and lower slopes). If it is less than the width of the connecting channel, the length of the main segment of the active side should be adjusted to be greater than the width of the connecting channel. Of course, step d can also be arranged between steps a and b, but the operation of adjusting the length of the main segment of the active side will have to be performed within the connecting channel. Due to the obstruction of the operating space by the upper and lower slopes, the overall adjustment process is relatively cumbersome.

[0106] Example 1

[0107] See Figure 14This embodiment provides an external connector that acts on a partition 52. The partition 52 has multiple inclined surfaces, including an upper inclined surface 59 and a lower inclined surface 53. The upper inclined surface 59 and the lower inclined surface 53 are parallel to each other, and a connecting channel 51 is provided between the upper inclined surface 59 and the lower inclined surface 53. The connecting channel 51 connects the inner and outer spaces of the partition 52. The external connector includes an action side, a stop block 60, and a nut sleeve 62. The action side includes a first end 55 that abuts against the lower inclined surface 53, a second end that abuts against the upper inclined surface 59, a main section 56 connecting the first end and the second end, and an external vertical rod 58 connected to the main section 56 via a rotating shaft. The bottom end of the lower inclined surface 53 has an extension section extending into the connecting channel 51. The extension section is connected to the bottom of the lower inclined surface 53. The first end 55 abuts against the groove 54. The abutting block 60 is provided with a through hole 61 for the external vertical rod 58 to pass through. The external vertical rod 58 is connected by a nut sleeve thread. During installation, the second end 57 is first inserted into the connecting channel 51, and then the first end 55 abuts against the groove 54. Pulling the external vertical rod 58 will cause the second end 57 to automatically abut against the upper inclined surface 59. Finally, the external vertical rod 58 is passed through the through hole 61 of the abutting block. By tightening the nut sleeve 62, the abutting block 60 can be firmly abutted against the bottom of the connecting channel 51, and the external vertical rod 58 can have a stable downward pulling force on the main section. This ensures that the first end and the second end of this embodiment firmly abut against the lower and upper inclined surfaces respectively, without shaking or falling off.

[0108] Figure 15 This is an improvement on the external vertical rod 58. The improved external vertical rod 58 includes an end 63 connected to the rotating shaft of the main section of the working side and an external vertical rod body. The end 63 has various universal interfaces for connecting with the external vertical rod. For example, in this embodiment, the end 63 is provided with a locking hole 64, and the external vertical rod body is provided with a locking head 65. After the external vertical rod body is inserted into the end 63, the locking head 65 is engaged with the locking hole 64, thus completing the firm connection between the end 63 and the external vertical rod body.

[0109] Example 2

[0110] See Figure 16 This embodiment is basically the same as Embodiment 1, except that the partition is an air conditioning outlet guide plate, and the main functional section is a telescopic section, including a fixed section 64 and a movable section 65. The fixed section 64 and the movable section 65 are threaded together. In addition, a fan 63 is connected to the lower end of the external vertical rod, and the rotating fan 63 can disperse the air conditioning air coming out of the connecting channel. The telescopic section can also adopt other structural forms, for example, see Figure 17The telescopic section includes a fixed segment 67 and a movable segment 66 that moves relative to the fixed segment 67 in the telescopic direction. Four engaging positions are provided between the fixed segment 67 and the movable segment 66 in the telescopic direction to engage the fixed segment 67 and the movable segment 66. In this embodiment, each engaging position has a different locking hole 68 but shares a common locking head 70. Alternatively, each engaging position can have its own set of locking holes and locking heads. The locking head 70 is disposed within the fixed segment 67, which has locking head holes 69 for the locking head 70 to protrude outwards. As the movable segment 66 moves along the telescopic direction, the locking head 70 enters different locking holes 68 through the locking head holes 69, resulting in different lengths for the telescopic section. For example, see... Figure 18 The telescopic section includes a fixed segment 76, a movable segment 71 that moves relative to the fixed segment 76 in the telescopic direction, and a tensioning element that fastens or loosens the movable segment 71 and the fixed segment 76. The tensioning element includes an inner ring sleeve and an outer ring sleeve 72 that is fitted onto the inner ring sleeve and threadedly connected to it. One end 75 of the inner ring sleeve is fixedly connected to the fixed segment 76, and the other end is provided with a compression ring 74 fitted onto the movable segment 71. The compression ring 74 has a compression gap 73. When the outer ring sleeve 72 moves towards the inner ring sleeve... When tightened, the inner surface of the outer ring 72 presses against the compression ring 74, reducing the diameter of the compression ring by narrowing the compression gap 73, thereby compressing the movable segment 71 and preventing the movable segment 71 from moving relative to the fixed segment 88. In practical use, adjust the telescopic length of the telescopic section to a suitable length, and then tighten the outer ring 72. When it is necessary to readjust the telescopic length of the telescopic section, rotate the outer ring 72 in the opposite direction to keep the outer ring 72 and the inner ring loose. After obtaining a suitable telescopic length, tighten the outer ring 72 again. For example, see... Figure 19 The telescopic section includes a fixed segment 77 and a movable segment that moves relative to the fixed segment 77 in the telescopic direction. The movable segment includes a rotating part 78 that is threadedly connected to the fixed segment 77 and a fixed part 79 that is stationary relative to the rotating part 78. The rotating part 78 rotates relative to the fixed part 79 around the axis of the telescopic section, thereby realizing the telescopic extension and contraction of the telescopic section. In this telescopic section, the rotating part 78 is threadedly connected to the fixed part 79, so that when the rotating part 78 rotates, the distance between the fixed segment 77 and the fixed part 79 in the movable segment is doubled or shortened.

[0111] Example 3

[0112] See Figure 20An external connector acts on a partition. The partition has multiple inclined surfaces, including an upper inclined surface 86 and a lower inclined surface 80. The upper inclined surface 86 and the lower inclined surface 80 are parallel to each other, and a connecting channel is provided between the upper inclined surface 86 and the lower inclined surface 80, connecting the inner and outer spaces of the partition. The external connector includes an external triangle formed by an action side, a horizontal side 88, and a pull side 87, and an external vertical rod 89. The action side includes a first end 81 that abuts against the lower inclined surface 80, a second end 85 that abuts against the upper inclined surface 86, and a main segment connecting the first end 81 and the second end 85. The side of the main segment near the first end 81 is connected to one end of the horizontal side 88 via a rotating shaft, and the side of the main segment near the second end 85 is connected to one end of the pull side 87 via a rotating shaft. The other end of 88 is connected to the other end of the pull edge 87 via a rotating shaft. The other end of the external vertical rod 89 is connected to the other end of the horizontal edge 88 via a rotating shaft. Both the main section of the action side and the horizontal edge 88 are provided with telescopic sections. Taking the telescopic section of the main section of the action side as an example, the telescopic section includes a fixed section 84, a movable section 82, a tensioning column passing through the fixed section 84 and the movable section 82, and a fixed clamping block 90 and a movable clamping block 83 located at both ends of the tensioning column. The movable clamping block 83 is threadedly connected to the tensioning column and is used to control the distance between the two clamping blocks, so that the movable section 82 and the fixed section 84 are fastened or loosened to each other, thereby achieving the purpose of controlling the telescopic length of the telescopic section. The connection relationship between the other main section of the action side, the horizontal edge, the pull edge, and the external vertical rod can be referred to the specific implementation method section.
