[0031] Figure 1A - Figure 1B Assembly schematic diagram and exploded view of the air conditioner box of the present application, where Figure 1A Schematic diagram of the box body with an adjustable seal plate of the present application in the assembled state; Figure 1B is Figure 1A Exploded view of the shown box body.

[0032] Figure 1A - Figure 1B Shows a part of the box body 100. As Figure 1A - Figure 1B shown, in the embodiment of the present application, the box body 100 is the box body of an air conditioner box. Those skilled in the art should understand that the box body can also be the box body used for other industrial products. The box body 100 includes box body panels arranged on the outer sides around the box body, including an upper side panel 112, a lower side panel 114, a left side panel 116, and a right side panel 118. Between the left side panel 116 and the right side panel 118, several horizontally extending slideways 122, 124, 126, 128 are provided for facilitating the installation of the seal plate and the filter to be pushed into and installed on the box body 100 along the extending direction of the slideways.

[0033] Continue as Figure 1A and Figure 1BAs shown, the box body 100 further includes several adjustable sealing plates 102, several fixed sealing plates 104, and several filters 132. The several adjustable sealing plates 102 include three adjustable sealing plates (102-1, 102-2, 102-3), and the several fixed sealing plates 104 include three fixed sealing plates (104-1, 104-2, 104-3). During installation, first install the several fixed sealing plates 104 into the box body 100 along the sliding ways 122, 124, 126, 128, then install each of the several filters 132 into the box body 100 along the sliding ways 122, 124, 126, 128 one by one, and finally install the several adjustable sealing plates 102 into the box body 100 along the sliding ways 122, 124, 126, 128. A sealing cotton 134 is pasted on the surface of each adjustable sealing plate or fixed sealing plate that fits the filter, which is used to play a better sealing role.

[0034] Continue as Figure 1B As shown, each of the several adjustable sealing plates 102 includes a first sealing plate 142, a second sealing plate 144 movably connected to the first sealing plate 142, and a fastening device 146. The fastening device 146 is respectively cooperatively connected with the first sealing plate 142 and the second sealing plate 144, and is used to lock the first sealing plate 142 and the second sealing plate 144 together so that they cannot move relative to each other. The adjustable sealing plate 102 includes a fastening state and a non-fastening state. In the fastening state, the fastening device 146 is tightened so that the second sealing plate 144 is fixedly connected to the first sealing plate 142; in the non-fastening state, the fastening device 146 is not tightened, thus allowing the second sealing plate 144 to be relatively movable with respect to the first sealing plate 142.

[0035] In the embodiment of the present application, the sliding ways are arranged in the horizontal direction. Those skilled in the art should understand that in some other embodiments, the sliding ways can also be arranged in the vertical direction.

[0036] In the embodiment of the present application, since the sliding ways 122, 124, 126, 128 are arranged to extend in the horizontal direction, the first sealing plate 142 and the second sealing plate 144 of each of the several adjustable sealing plates 102 are arranged such that the second sealing plate 144 can be adjusted relative to the first sealing plate 142 in the horizontal direction. Those skilled in the art should understand that in some other embodiments, if the sliding ways are arranged in the vertical direction, the first sealing plate 142 and the second sealing plate 144 can also be arranged such that the second sealing plate 144 can be adjusted relative to the first sealing plate 142 in the vertical direction.

[0037] In the embodiment of the present application, the number of both the adjustable sealing plates and the fixed sealing plates is three. Those skilled in the art should understand that in some other embodiments, the number of the adjustable sealing plates and the fixed sealing plates is not limited to three. According to different box body sizes, the number of the adjustable sealing plates and the fixed sealing plates can also be less than three or more than three.

[0038] Figure 2A - 2B shows the specific structure of the first embodiment of the adjustable sealing plate of the present application, where Figure 2A is a schematic diagram of the first embodiment of the adjustable sealing plate of the present application; Figure 2B is Figure 2A an exploded view of the adjustable sealing plate shown.

[0039] As Figure 2A - 2B shown, each component of several adjustable sealing plates 102 includes a first sealing plate 142, a second sealing plate 144, and a fastening device 146 as described above, and further includes a distance adjusting device 212. The distance adjusting device 212 includes a telescopic structure, such as a jacking screw mechanism. The elongation and shortening of the telescopic structure can actuate the second sealing plate 144 to move relative to the first sealing plate 142, thereby adjusting the size of the adjustable sealing plate 102. Specifically, the telescopic structure of the distance adjusting device 212 includes a fixed end 202 and an adjusting end 204. The fixed end 202 is fixedly arranged on the first sealing plate 142. The adjusting end 204 is movably connected to the fixed end 202, and the adjusting end 204 is actuably connected to the second sealing plate 144, that is, the movement of the adjusting end 204 can actuate the second sealing plate 144 to move relative to the first sealing plate 142, thereby adjusting the size of the adjustable sealing plate 102.

[0040] In the embodiment of the present application, the fixed end 202 includes a fixed nut 242 fixedly installed thereon. The adjusting end 204 includes an adjusting screw 244. The rotation of the adjusting screw 244 relative to the fixed nut 242 can cause the adjusting screw 244 to move axially relative to the fixed nut 242, and the adjusting screw 244 is arranged to be actuably connected to the second sealing plate 144.

[0041] Those skilled in the art should understand that in some other embodiments, the fixed end 202 and the adjusting end 204 can also be set as follows: the fixed end 202 includes a fixed screw fixedly installed thereon, the adjusting end 204 includes an adjusting nut, the rotation of the adjusting nut relative to the fixed screw can cause it to move axially along the fixed screw, and the adjusting nut is arranged to be actuably connected to the second sealing plate 144.

[0042] Continuing as Figure 2A - 2B shown, each of the first sealing plate 142 and the second sealing plate 144 includes an L-shaped structure. The L-shaped structure provides an installation space for the distance adjusting device 212. For example, the distance adjusting device 212 can be arranged inside the L-shaped structure of the first sealing plate 142. As Figure 2AAs shown, in the installed state, a part of the first sealing plate 142 and the second sealing plate 144 overlap each other, which enables the first sealing plate 142 and the second sealing plate 144 to have a certain area of mutually contacting surface parts, thereby achieving a better sealing effect between the first sealing plate 142 and the second sealing plate 144.

[0043] As Figure 2B shown, the first sealing plate 142 has a first sealing plate side wall 252 and a first sealing plate front wall 254, and the first sealing plate side wall 252 and the first sealing plate front wall 254 are connected to each other to form an L-shaped structure; the second sealing plate 144 has a second sealing plate side wall 262 and a second sealing plate front wall 264, and the second sealing plate side wall 262 and the second sealing plate front wall 264 are connected to each other to form an L-shaped structure. A first hole 222 is provided on the first sealing plate front wall 254, and a second hole 224 is provided on the second sealing plate front wall 264. The fastening device 146 passes through the first hole 222 and the second hole 224 along a first direction, and this first direction is the direction perpendicular to the sealing plate surface of the adjustable sealing plate 102 and facing inwards. A space allowing the fastening device 146 to move along a second direction is provided on the first hole 222, and this second direction is the size adjustment direction of the adjustable sealing plate 102, that is, the horizontal direction, and the second direction is perpendicular to the first direction. In the non-fastening state of the adjustable sealing plate 102, the fastening device 146 can move along the second direction in the first hole 222. In the embodiments of the present application, the first hole 222 is an oblong hole. Those skilled in the art should understand that in some other embodiments, the first hole may also be a rectangular hole or other holes or grooves allowing the fastening device 146 to translate therein. The second hole 224 is a round hole, so the fastening device 146 cannot translate along the second direction in the second hole 224.

[0044] Those skilled in the art should understand that in some other embodiments, the second hole 224 may also be provided on the first sealing plate 142, and the first hole 222 may be provided on the second sealing plate 144.

[0045] Continuing as Figure 2B shown, the fixed end 202 and its fixing nut 242 are fixedly installed on the first sealing plate side wall 252 and protrude from the first sealing plate side wall 252. The fixed end 202 further includes a fixed end cavity (not shown in the figure) that can accommodate one end of the adjusting screw 244, so that the adjusting screw 244 can be telescoped relative to the fixed end 202 by rotation in the fixed end cavity.

[0046] Continuing as Figure 2BAs shown, the fastening device 146 includes a fastening bolt 232 and a fastening nut 234. The fastening bolt 232 passes through the first hole 222 and the second hole 224. In the unfastened state, the fastening bolt 232 is received in the first hole 222 and can move in the second direction. The adjustable sealing plate 102 further includes a mating device. In the embodiment of the present application, the mating device is a mating nut 246, which is used to assist in keeping the adjustment end 204 and the fastening device 146 in a butting state. Specifically, the mating nut 246 is disposed at the other end of the adjusting screw 244 relative to the fixed end 202. The adjusting screw 244 can extend into the mating nut in the second direction, and the fastening bolt 232 of the fastening device 146 can pass through the mating nut 246 in the first direction. Those skilled in the art should understand that the mating device is not limited to the structure of the mating nut, and other structures for holding the adjusting screw and the fastening bolt can also be used.

[0047] Figure 3A - 3B A schematic diagram showing the cooperation between the adjusting screw and the fastening bolt is shown, in which, Figure 3A is Figure 2A a schematic diagram of the mating nut installed between the adjusting screw and the fastening bolt in the adjustable sealing plate shown; Figure 3B is Figure 2A a schematic diagram showing the cooperation between the adjusting screw and the fastening bolt through the mating nut in the adjustable sealing plate shown.

[0048] As Figure 3A shown, the mating nut 246 has a central hole 302 axially penetrating therethrough, and a screw receiving hole 304 provided on its side surface. The screw receiving hole 304 can be arranged to communicate with the space of the central hole 302, or arranged in the form of a counterbore. No thread is provided in the screw receiving hole 304, and the screw receiving hole 304 and the adjusting screw 244 are in clearance fit, so that the adjusting screw 244 can freely perform axial movement or rotation relative to the screw receiving hole 304.

[0049] As Figure 3BAs shown, in the installed state, the fastening bolt 232 passes through the central hole 302 of the mating nut 246, and the adjusting screw 244 extends into the screw receiving hole 304 and abuts against the fastening bolt 232 in the screw receiving hole 304 or abuts against the bottom of the counterbore of the screw receiving hole 304. When the adjusting screw 244 extends relative to the fixed end 202 in the second direction, the above-mentioned abutting action can actuate the fastening bolt 232 and the mating nut 246 to move in the same direction as the extending direction of the adjusting screw 244 (i.e., the second direction). Since the fastening bolt 232 passes through the second hole 224 in the second sealing plate 144 in the first direction, the movement of the fastening bolt 232 in the second direction can drive the second sealing plate 144 to move in the second direction at the same time, so that the second sealing plate 144 extends a distance relative to the first sealing plate 142. When the adjusting screw 244 retracts relative to the fixed end 202 in the second direction, the above-mentioned abutting action disappears, and a distance is spaced between the adjusting screw 244 and the fastening bolt 232 and the mating nut 246, so that the fastening bolt 232 and the mating nut 246 can move a corresponding distance in the direction of retraction of the adjusting screw 244, thereby driving the second sealing plate 144 to move a corresponding distance relative to the first sealing plate 142.

[0050] Figure 4A - 5B The figure shows a schematic diagram of the adjustment process of the adjustable sealing plate, where, Figure 4A is Figure 2A a top view of the adjustable sealing plate shown in the shortened state; Figure 4B is Figure 4A a perspective view of the adjustable sealing plate shown in the shortened state from the inner side view; Figure 5A is Figure 2A a top view of the adjustable sealing plate shown in the extended state; Figure 5B is Figure 5A a perspective view of the adjustable sealing plate shown in the extended state from the inner side view.

[0051] As Figure 4A - 4B shown, it shows the shortened state of the telescopic structure of the adjustable sealing plate 102. In the shortened state, the adjusting screw 244 of the distance adjusting device 212 is in the left position in the figure relative to the fixed end 202, that is, the retracted position, and the fastening device 146 and the mating nut 246 are also in the left position in the figure accordingly. The fastening bolt 232 of the fastening device 146 is also in the left position of the hole in the first hole 222 (slotted hole). At this time, the second sealing plate 144 is in the left position in the figure relative to the first sealing plate 142, the fastening device 146 is not tightened, and the adjustable sealing plate 102 is in the unfastened state, so it can be freely adjusted. At this time, the length of the adjustable sealing plate is D1.

[0052] After the adjustable sealing plate 102 is installed in the box body 100, the filter needs to be compressed and sealed, and the length of the adjustable sealing plate needs to be adjusted to compensate for the installation tolerance of the sealing plate. When the adjustable sealing plate 102 is not tightened, the adjusting screw 244 is rotated relative to the fixing nut 242 of the fixed end 202, so that the adjusting screw 244 extends in the second direction relative to the fixed end 202, thereby actuating the fastening device 146 and the matching nut 246 to move in the second direction, and at the same time driving the second sealing plate 144 to move in the same direction relative to the first sealing plate 142. After the adjustable sealing plate 102 has compressed the filter and compensated for the installation tolerance of the sealing plate, the adjustable sealing plate 102 is in a position such as Figure 5A - 5B Status shown.

[0053] like Figure 5A - 5B As shown, the extended state of the telescopic structure of the adjustable sealing plate 102 is shown. In the extended state, the adjusting screw 244 of the distance adjustment device 212 is in the right position in the figure relative to the fixed end 202, that is, the extended position, the fastening device 146 and the matching nut 246 are also in the right position in the figure accordingly, the fastening bolt 232 of the fastening device 146 is also in the right position of the hole in the first hole 222 (waist hole), and the second sealing plate 144 is in the right position in the figure relative to the first sealing plate 142. At this time, the length of the adjustable sealing plate is D2, and D2 is greater than D1. In this state, the fastening nut 234 is turned to tighten the fastening device 146, thereby locking the first sealing plate 142 and the second sealing plate 144 together, and the adjustable sealing plate 102 is in a fastened state.

[0054] Continue as Figure 5A - 5B As shown, the distance adjustment device 212 also includes an adjustment device fastening nut 272, which is used to turn the adjustment screw 244, and can also fix the adjustment screw 244 at a specific position relative to the fixed end 202. The adjustment device fastening nut 272 can have a double nut structure, or a structure with more than two nuts, which is connected to the adjustment screw 244 by threaded matching. Before tightening the fastening nut 234, the adjustment device fastening nut 272 can be tightened first, specifically tightening the adjustment device fastening nut 272 in the direction of the fixed nut 242 and squeezing and fitting it, so as to lock the adjustment screw 244 at the length extended relative to the fixed end 202 at this time. After the length of the adjustment screw 244 is locked, the fastening nut 234 is tightened again, so that the adjustable sealing plate 102 is kept in a tightened state. Under the dual tightening action of the adjustment device fastening nut 272 and the fastening nut 234, the adjustable sealing plate 102 is less likely to loosen, and a better tightening effect can be achieved.

[0055] Figure 6Schematic diagram of the second embodiment of the adjustable sealing plate of the present application. The difference between the second embodiment of the adjustable sealing plate and the first embodiment is that the second embodiment does not have a fastening device, but rivets the second sealing plate and the first sealing plate together by a relatively slidable manner.

[0056] As Figure 6 shown, the adjustable sealing plate 602 includes a first sealing plate 632, a second sealing plate 634, and a distance adjustment device 612. Similar to the first embodiment, the first sealing plate 632 is an L-shaped structure, including a first sealing plate side wall 652, and the distance adjustment device 612 is installed on the first sealing plate side wall 652. This L-shaped structure provides an installation space for the distance adjustment device 612. For example, the distance adjustment device 612 can be arranged inside the L-shaped structure of the first sealing plate 632. Different from the first embodiment, the second sealing plate 634 is a concave structure, and this concave structure includes a second sealing plate side wall 662 close to the first sealing plate 632, which is used to connect with the distance adjustment device 612 so that the distance adjustment device 212 is connected between the first sealing plate 632 and the second sealing plate 634. The distance adjustment device 212 includes a telescopic structure, such as a jacking screw mechanism. The elongation and shortening of this telescopic structure can actuate the second sealing plate 634 to move relative to the first sealing plate 632, so that the second sealing plate 634 and the first sealing plate 632 are movably connected, thereby adjusting the size of the adjustable sealing plate 602. The telescopic structure of the distance adjustment device 612 includes a fixed end 642 and an adjustment end 644, and the adjustment end 644 is movably connected to the fixed end 642. In this second embodiment, the fixed end 642 is a bolt or a screw rod, and the adjustment end 644 is a nut assembly installed on the bolt or the screw rod. This nut assembly includes a first nut 644-1 arranged on the left side of the second sealing plate side wall 662 and a second nut 644-2 arranged on the right side of the second sealing plate side wall 662. The fixed end 642 is installed on the first sealing plate side wall 652 of the first sealing plate 632 and passes through a hole (not shown in the figure) reserved on the second sealing plate side wall 662, and the first nut 644-1 and the second nut 644-2 are respectively attached to both sides of the hole reserved on the second sealing plate side wall 662.

[0057] Similar to the first embodiment, a first hole 622 is provided on the first sealing plate 632, and a second hole 624 is provided on the second sealing plate 634. The movable rivet 672 passes through the first hole 622 and the second hole 624 along the first direction. The first hole 622 is a waist-shaped hole, a rectangular hole, or other holes or grooves that allow the movable rivet 672 to translate along the second direction therein, and the second hole 624 is a round hole. Therefore, the movable rivet 672 cannot translate along the second direction in the second hole 624. The first sealing plate 632 and the second sealing plate 634 are movably riveted in the above manner, so that the second sealing plate 634 can only slide relative to the first sealing plate 632 along the second direction, and cannot move relative to the first sealing plate 632 in a direction other than the second direction.

[0058] During the process of extending the adjustable seal plate 602, the second nut 644-2 can be rotated to a loosening position relatively to the right of the fixed end 642. By rotating the first nut 644-1, the second seal plate side wall 662 is actuated to move to the right, so as to extend the adjustable seal plate 602 to the target length. Then, the second nut 644-2 is rotated to the left and fixed on the right side of the second seal plate side wall 662, so as to lock the first seal plate 632 and the second seal plate 634 at the target length, thereby adjusting the adjustable seal plate 602 to the target size. During the process of shortening the adjustable seal plate 602, the first nut 644-1 can be rotated to a loosening position relatively to the left of the fixed end 642. By rotating the second nut 644-2, the second seal plate side wall 662 is actuated to move, so as to shorten the adjustable seal plate 602 to the target length. Then, the first nut 644-1 is rotated to the right and fixed on the left side of the second seal plate side wall 662, so as to lock the first seal plate 632 and the second seal plate 634 at the target length, thereby adjusting the adjustable seal plate 602 to the target size.

[0059] Those skilled in the art should understand that in some other embodiments, the second hole 624 can also be arranged on the first seal plate 632, and the first hole 622 can be arranged on the second seal plate 634. The fixed end 642 can also be a nut assembly, and the adjusting end 644 is correspondingly a bolt or a lead screw.

[0060] The inventor of the present application has found through long-term experiments and research that in the existing air-conditioning box body, the box body panels on the outer sides around the box body are closed, and the size of the box body cannot be adjusted. There are manufacturing errors in the manufacturing of the filter and the seal plate, and there are assembly errors during assembly, so that in the installed state, the filter and the seal plate cannot be closely matched. Especially after the unit is transported, since the filter is not pressed by the seal plate, there is a negative tolerance, and the filter will have different degrees of displacement, resulting in its being serpentine (wavy), making the box body not tightly sealed and the filtering efficiency poor. When there is a positive tolerance, the assembly of the filter and the seal plate is more difficult, resulting in high installation strength and low installation efficiency.

[0061] The inventor of the present application has found through long-term experiments and research that the seal plate can be designed to have an adjustable structure, so as to facilitate the tolerance control at the design end and there is no need to consider manufacturing and assembly tolerances. Therefore, the adjustable seal plate of the present application has the following advantages:

[0062] First, it reduces the manufacturing difficulty of the supplier, can bend the sheet metal according to the normal process, improves the processing efficiency, and reduces the cost;

[0063] Second, it is convenient for installation on the production line. There is no need to forcibly press in the seal plate, so that the sealing cotton will not be damaged, and there is no need to make up for the insufficient size by pasting cotton;

[0064] Third, the sealing will not be damaged during transportation, reducing bypass leakage and having no impact on the filtration efficiency of the filter.

[0065] Fourth, during maintenance, simply loosen the pressing device to quickly remove the filter, avoiding damage to the filter frame and sealing cotton caused by forced manual removal. The operation is simple.

[0066] Fifth, the adjustable sealing plate structure of the present application is simple and convenient for production and manufacturing.
