[0001] This application relates to the technical field of kitchen appliances, and more particularly, to a range hood. Background Art

[0002] To reduce the assembly complexity of the condensation plate of the range hood, facilitate the operation of the operator, and at the same time facilitate the cleaning and maintenance of the condensation plate, in the related art, the condensation plate is usually installed on the range hood through a quick-release component. However, the quick-release component is usually not installed firmly, with poor reliability, and is easily caused by external collision or vibration to cause accidental detachment of the condensation plate, thereby causing the condensation plate to fail or even be damaged. Utility Model Content

[0003] An embodiment of this application provides a range hood.

[0004] The range hood according to the embodiment of this application includes:

[0005] A main body, the main body includes a first component and a second component;

[0006] A connection component, the connection component includes a support and a bracket, the support and the bracket are detachably rotatably connected, the support is connected to the first component, and the bracket is connected to the second component, so as to detachably rotatably connect the first component and the second component.

[0007] In the range hood according to the embodiment of this application, the first component may be a mounting plate, and the second component may be a condensation plate. By connecting the support to the first component or the mounting plate, and connecting the bracket to the second component or the condensation plate, the first component and the second component or the mounting plate and the condensation plate are quickly and detachably rotatably connected.

[0008] In some embodiments, the connection component includes:

[0009] A support, the support includes a connecting portion, a guiding column, and a locking protrusion, the connecting portion is used for connecting to the first component, the guiding column is connected to the connecting portion, and the locking protrusion is disposed on the side surface of the guiding column;

[0010] A bracket, the bracket includes a mounting portion and a connecting plate, the mounting portion is used for connecting to the second component, the connecting plate is connected to the mounting portion, and the connecting plate is formed with a locking hole that cooperates with the locking protrusion;

[0011] The guiding column is inserted into the locking hole and the locking protrusion passes through the locking hole, so that the connecting plate is limited between the locking protrusion and the connecting portion.

[0012] In this way, by connecting with the first component through the connecting part, the support can be fixed on the first component or the mounting plate. By connecting with the second component through the mounting part, the bracket can be fixed on the second component or the condensation plate. Then, by inserting the guiding column into the locking hole and passing through the locking protrusion, the connecting plate is limited between the locking protrusion and the connecting part, and the first component and the second component, or the mounting plate and the condensation plate, can be quickly and detachably rotationally connected.

[0013] In some embodiments, the locking protrusion includes a first locking protrusion and a second locking protrusion. The first locking protrusion and the second locking protrusion are arranged at intervals along the axial direction of the guiding column on the side surface of the guiding column. The guiding column is inserted into the locking hole, and the first locking protrusion and the second locking protrusion pass through the locking hole in sequence, so that the connecting plate is limited between the second locking protrusion and the connecting part. The orthographic projections of the first locking protrusion and the second locking protrusion on the connecting plate are at least partially staggered.

[0014] In this way, during the rotation of the second component relative to the first component, or the condensation plate relative to the mounting plate, the second locking protrusion cooperates with the locking hole, resulting in the second locking protrusion sliding out of the locking hole. However, since the orthographic projections of the first locking protrusion and the second locking protrusion on the connecting plate are at least partially staggered, at this time, the first locking protrusion is also staggered from the locking hole. Therefore, the connecting plate cannot escape from the first locking protrusion, preventing the second component from falling off the first component during rotation, or the condensation plate from falling off the mounting plate during rotation.

[0015] In some embodiments, the first locking protrusion includes at least two first protrusions, and the two first protrusions are evenly arranged along the circumferential direction of the guiding column; and / or

[0016] The second locking protrusion includes at least two second protrusions, and the two second protrusions are evenly arranged along the circumferential direction of the guiding column.

[0017] In this way, the two first protrusions and the two second protrusions can share the stress, which is beneficial to improving the service life of the first locking protrusion and the second locking protrusion.

[0018] In some embodiments, a first guiding part is arranged on the side of the first protrusion away from the connecting part; and / or

[0019] A second guiding part is arranged on the side of the second protrusion away from the connecting part.

[0020] In this way, the first guiding part facilitates the insertion and locking of the first protrusion, and the second guiding part facilitates the insertion and locking of the second protrusion, facilitating the use of the quick-release support.

[0021] In some embodiments, the orthographic projection of the end face of the second guiding portion on the connecting plate is located within the orthographic projection of the first protrusion on the connecting plate.

[0022] In this way, after the first locking protrusion passes through the lock hole, the edge of the lock hole will directly fall on the second guiding portion, so that the second guiding portion can directly guide the second locking protrusion through the lock hole without jamming, which is beneficial to further reducing the locking difficulty of the quick-release support.

[0023] In some embodiments, the first locking protrusion is symmetric about a first symmetry line, the second locking protrusion is symmetric about a second symmetry line, the first symmetry line and the second symmetry line extend along the radial direction of the guiding column, and the included angle between the first symmetry line and the second symmetry line is less than 90°.

[0024] In this way, since the first component can only rotate relative to the second component by 90°, if the included angle between the first symmetry line and the second symmetry line is greater than 90°, it will be difficult for the first component and the second component to be quickly disassembled and assembled. Therefore, the included angle between the first symmetry line and the second symmetry line should be less than 90° to facilitate reducing the disassembly and assembly difficulty of the first component and the second component.

[0025] In some embodiments, the interval between the second locking protrusion and the connecting portion is greater than the thickness of the connecting plate and less than 1.2 times the thickness of the connecting plate.

[0026] In this way, while not affecting the rotation of the connecting plate on the guiding column, the movable range of the connecting plate between the second locking protrusion and the connecting portion is restricted, which is beneficial to reducing the possibility of the connecting plate disengaging from the second locking protrusion. At the same time, restricting the movable range of the connecting plate between the second locking protrusion and the connecting portion can also reduce the wear of the connecting plate on the guiding column.

[0027] In some embodiments, the interval between the first locking protrusion and the second locking protrusion along the axial direction of the guiding column is greater than the thickness of the connecting plate and less than 1.2 times the thickness of the connecting plate.

[0028] In this way, while not affecting the rotation of the connecting plate on the guiding column between the first locking protrusion and the second locking protrusion, the movable range of the connecting plate here is restricted, which is beneficial to reducing the possibility of the connecting plate disengaging from the first locking protrusion. At the same time, restricting the movable range of the connecting plate can also reduce the wear of the connecting plate on the guiding column.

[0029] In some embodiments, a third guiding portion is provided on the side of the guiding column away from the connecting plate.

[0030] In this way, the third guiding portion can be used to guide the guiding column to insert into the lock hole, facilitating the disassembly and assembly of the connecting assembly.

[0031] In some embodiments, the connecting portion includes a connected support plate and a fixing plate. The fixing plate is used to connect with the first component, the guiding column is connected with the support plate, and the connecting portion further includes a reinforcing rib. One end of the reinforcing rib is connected with the support plate, and the other end of the reinforcing rib is connected with the fixing plate.

[0032] Thus, it is beneficial to improve the structural strength of the support, beneficial to extend the service life of the support, and reduce the maintenance cost of the support.

[0033] In some embodiments, the number of the lock holes is two, and the two lock holes are arranged at both ends of the connecting plate.

[0034] Thus, both ends of the bracket can be quickly disassembled and assembled with the support, which is beneficial for the bracket to adapt to more installation scenarios.

[0035] In some embodiments, the number of the supports is two, the two supports are arranged at intervals on the first component, the axes of the two guiding columns are located on the same straight line, the number of the brackets is two, the two brackets are arranged at intervals on the second component, and the brackets and the supports are arranged in one-to-one correspondence.

[0036] Thus, the cooperation of the two supports and brackets is beneficial to improve the reliability of the detachable rotational connection between the first component and the second component.

[0037] In some embodiments, the guiding columns of the two supports face the same side.

[0038] Thus, it is convenient for the quick disassembly and assembly between the first component and the second component.

[0050] To reduce the assembly complexity of the condensate plate of the range hood, facilitate the operation of the operator, and at the same time facilitate the cleaning and maintenance of the condensate plate, in the related art, the condensate plate is usually installed on the range hood through a quick-release component. However, the quick-release component is usually not installed firmly and has poor reliability. It is very easy for the condensate plate to accidentally come off due to external collision or vibration, which may further lead to the failure or even damage of the condensate plate.

[0051] Please refer to Figure 1 , an embodiment of this application provides a range hood 100. The range hood 100 includes a main body and a connecting component 10. The main body includes a first component 20 and a second component 30; the connecting component 10 includes a support 11 and a bracket 12. The support 11 and the bracket 12 are detachably and rotatably connected. The support 11 is connected to the first component 20, and the bracket 12 is connected to the second component 30, so as to detachably and rotatably connect the first component 20 and the second component 30.

[0052] For the range hood 100 according to the embodiment of this application, the first component 20 may be a mounting plate, and the second component 30 may be a condensate plate. By connecting the support 11 to the first component 20 or to the mounting plate, and connecting the bracket 12 to the second component 30 or to the condensate plate, the first component 20 and the second component 30, or the mounting plate and the condensate plate, are quickly and detachably rotatably connected.

[0053] In other embodiments, the first component 20 may be the condensation plate of the range hood 100, and the second component 30 may be the mounting plate of the range hood 100.

[0054] In some embodiments, the connecting assembly 10 includes a support 11 and a bracket 12. The support 11 includes a connecting portion 111, a guiding column 112, and a locking projection. The connecting portion 111 is used to connect with the first component 20. The guiding column 112 is connected to the connecting portion 111, and the locking projection is arranged on the side surface of the guiding column 112. The bracket 12 includes a mounting portion 121 and a connecting plate 122. The mounting portion 121 is used to connect with the second component 30. The connecting plate 122 is connected to the mounting portion 121, and a locking hole 123 that cooperates with the locking projection is formed in the connecting plate 122. The guiding column 112 is inserted into the locking hole 123 and the locking projection passes through the locking hole 123, so that the connecting plate 122 is limited between the locking projection and the connecting portion 111.

[0055] In this way, the support 11 can be fixed on the first component 20 or the mounting plate by connecting the connecting portion 111 with the first component 20. The bracket 12 can be fixed on the second component 30 or the condensation plate by connecting the mounting portion 121 with the second component 30. Then, by inserting the guiding column 112 into the locking hole 123 and passing through the locking projection to limit the connecting plate 122 between the locking projection and the connecting portion 111, the first component 20 and the second component 30 or the mounting plate and the condensation plate can be quickly and detachably rotationally connected.

[0056] In some embodiments, the locking projection includes a first locking projection 113 and a second locking projection 114. The first locking projection 113 and the second locking projection 114 are arranged at intervals along the axial direction of the guiding column 112 on the side surface of the guiding column 112. The guiding column 112 is inserted into the locking hole 123 and the first locking projection 113 and the second locking projection 114 pass through the locking hole 123 in sequence, so that the connecting plate 122 is limited between the second locking projection 114 and the connecting portion 111. The orthographic projections of the first locking projection 113 and the second locking projection 114 on the connecting plate 122 are at least partially staggered.

[0057] In this way, during the rotation of the second component 30 relative to the first component 20 or the condensation plate relative to the mounting plate, the second locking projection 114 cooperates with the locking hole 123, resulting in the second locking projection 114 sliding out of the locking hole 123. However, since the orthographic projections of the first locking projection 113 and the second locking projection 114 on the connecting plate 122 are at least partially staggered, at this time, the first locking projection 113 is also staggered from the locking hole 123. Therefore, the connecting plate 122 cannot escape from the first locking projection 113, preventing the second component 30 from falling off the first component 20 during rotation, or preventing the condensation plate from falling off the mounting plate during rotation.

[0058] Specifically, the connecting portion 111 is provided with fixing holes for connecting with the mounting plate, and the connecting portion 111 is detachably arranged on the mounting plate through fasteners passing through the fixing holes. The mounting portion 121 is also provided with fixing holes, and the mounting portion 121 is detachably arranged on the condensation plate through fasteners passing through the fixing holes.

[0059] The support 11 is an integrally formed one-piece structure, and similarly, the bracket 12 is also an integrally formed one-piece structure.

[0060] In other embodiments, the support 11 and the mounting plate may also be an integrally formed one-piece structure, and similarly, the bracket 12 and the condensation plate are also an integrally formed one-piece structure.

[0061] Please refer to Figure 2 , in some embodiments, the first locking protrusion 113 includes at least two first protrusions 1131, and the two first protrusions 1131 are evenly arranged along the circumferential direction of the guide post 112; and / or the second locking protrusion 114 includes at least two second protrusions 1141, and the two second protrusions 1141 are evenly arranged along the circumferential direction of the guide post 112.

[0062] In this way, the two first protrusions 1131 and the two second protrusions 1141 can share the stress, which is beneficial to improving the service life of the first locking protrusion 113 and the second locking protrusion 114.

[0063] Specifically, in this embodiment, a total of two first protrusions 1131 are provided, and the two first protrusions 1131 are symmetric about the axis of the guide post 112. Similarly, the two second protrusions 1141 are symmetric about the axis of the guide post 112.

[0064] For convenient processing, the first protrusion 1131 and the second protrusion 1141 have exactly the same shape and size. Further, the first protrusion 1131 is columnar, and the side surface of the columnar first protrusion 1131 is connected to the side surface of the guide post 112. In this embodiment, the cross-section of the first protrusion 1131 is a rectangle and a semicircle spliced together.

[0065] Please refer to Figure 2 , in some embodiments, a first guiding portion 1132 is arranged on the side of the first protrusion 1131 away from the connecting portion 111; and / or a second guiding portion 1142 is arranged on the side of the second protrusion 1141 away from the connecting portion 111.

[0066] In this way, the first guiding portion 1132 facilitates the insertion and locking of the first protrusion 1131, and the second guiding portion 1142 facilitates the insertion and locking of the second protrusion 1141, which is convenient for the use of the quick-release support 11.

[0067] Specifically, the first guiding portion 1132 and the second guiding portion 1142 have the same shape. In this embodiment, the first guiding portion 1132 is approximately frustum-shaped. A first guiding surface is provided on the side surface of the first guiding portion 1132. The first guiding surface includes a conical surface and inclined surfaces located on both sides of the conical surface.

[0068] Further, in this embodiment, transition rounded corners are provided at the joints between all surfaces of the first locking protrusion 113.

[0069] Please refer to Figure 3 , in some embodiments, the orthographic projection of the end surface of the second guiding portion 1142 on the connecting plate 122 is located within the orthographic projection of the first protrusion 1131 on the connecting plate 122.

[0070] In this way, after the first locking protrusion 113 passes through the lock hole 123, the edge of the lock hole 123 will directly fall on the second guiding portion 1142. Thus, the second guiding portion 1142 can directly guide the second locking protrusion 114 to pass through the lock hole 123 without jamming, which is beneficial to further reducing the locking difficulty of the quick-release support 11.

[0071] Specifically, when installing the condensation plate, usually the lock hole 123 on the connecting plate 122 is first sleeved on the guiding column 112, and then through translation and rotation, the first locking protrusion 113 and the second locking protrusion 114 pass through the lock hole 123 in sequence. The orthographic projection of the end surface of the second guiding portion 1142 on the connecting plate 122 being located within the orthographic projection of the first protrusion 1131 on the connecting plate 122 allows the operator, when installing the condensation plate, after the first locking protrusion 113 is aligned with the lock hole 123 and translated, the first locking protrusion 113 passes through the lock hole 123. At this time, without rotation, just continue to translate, and the edge of the lock hole 123 will directly fall on the second guiding portion 1142. Under the guiding action of the second guiding portion 1142, the second locking protrusion 114 can easily pass through the lock hole 123.

[0072] In this embodiment, the orthographic projection of one side edge of the first guiding surface on the connecting plate 122 should exactly fall within the orthographic projection of the second guiding surface.

[0073] In some embodiments, the first locking protrusion 113 is symmetric about a first symmetry line, the second locking protrusion 114 is symmetric about a second symmetry line. The first symmetry line and the second symmetry line extend along the radial direction of the guiding column 112 and the included angle between the first symmetry line and the second symmetry line is less than 90°.

[0074] Thus, since the first component 20 can only rotate 90° relative to the second component 30, if the angle between the first symmetry line and the second symmetry line is greater than 90°, it will be difficult to quickly disassemble and assemble the first component 20 and the second component 30. Therefore, the angle between the first symmetry line and the second symmetry line should be less than 90° to facilitate reducing the disassembly and assembly difficulty of the first component 20 and the second component 30.

[0075] Specifically, in this embodiment, the condensation plate can usually only rotate about 90° during use. When there is only one first protrusion 1131 and one second protrusion 1141, if the first symmetry line and the second symmetry line extend along the radial direction of the guiding post 112 and the angle between the first symmetry line and the second symmetry line is greater than 90°, the condensation plate cannot be installed due to the fact that the condensation plate can only rotate 90°. Therefore, when there is only one first protrusion 1131 and one second protrusion 1141, the first symmetry line and the second symmetry line extend along the radial direction of the guiding post 112 and the angle between the first symmetry line and the second symmetry line should be less than 90°.

[0076] When the number of the first protrusions 1131 and the second protrusions 1141 exceeds one and multiple first protrusions 1131 and second protrusions 1141 are evenly circumferentially distributed on the side surface of the guiding post 112, due to the increase in the number, only the minimum angle should be less than 90°. And when the number of the first protrusions 1131 and the second protrusions 1141 exceeds two, the maximum of the minimum angle will not exceed 90°. Therefore, at this time, there is no need to consider the size of the angle.

[0077] Please refer to Figure 2 , in some embodiments, the interval between the second locking protrusion 114 and the connecting portion 111 is greater than the thickness of the connecting plate 122 and less than 1.2 times the thickness of the connecting plate 122.

[0078] Thus, while not affecting the rotation of the connecting plate 122 on the guiding post 112, the movable range of the connecting plate 122 between the second locking protrusion 114 and the connecting portion 111 is restricted, which is beneficial to reducing the possibility of the connecting plate 122 disengaging from the second locking protrusion 114. At the same time, restricting the movable range of the connecting plate 122 between the second locking protrusion 114 and the connecting portion 111 can also reduce the wear of the connecting plate 122 on the guiding post 112.

[0079] Specifically, since after normal installation, the connecting plate 122 should be rotatably arranged between the second locking protrusion 114 and the connecting portion 111 in a detachable manner, there should be sufficient distance between the second locking protrusion 114 and the connecting portion 111 for the connecting plate 122 to rotate without being hindered. Therefore, the interval between the second locking protrusion 114 and the connecting portion 111 is greater than the thickness of the connecting plate 122 and less than 1.2 times the thickness of the connecting plate 122.

[0080] In this embodiment, the interval between the second locking projection 114 and the connecting portion 111 should be slightly larger than the thickness of the connecting plate 122. Further, to reduce the friction between the connecting plate 122 and the guiding column 112, grease can be applied between the guiding column 112 and the connecting plate 122.

[0081] In some embodiments, the interval between the first locking projection 113 and the second locking projection 114 along the axial direction of the guiding column 112 is greater than the thickness of the connecting plate 122 and less than 1.2 times the thickness of the connecting plate 122.

[0082] In this way, while not affecting the rotation of the connecting plate 122 on the guiding column 112 between the first locking projection 113 and the second locking projection 114, the movable range of the connecting plate 122 here is restricted, which is beneficial to reducing the possibility of the connecting plate 122 disengaging from the first locking projection 113. At the same time, restricting the movable range of the connecting plate 122 can also reduce the wear of the connecting plate 122 on the guiding column 112.

[0083] Specifically, when the condensation plate is subjected to an external force such that the second locking projection 114 disengages from the locking hole 123, due to the blocking of the first locking projection 113, the connecting plate 122 can be rotated and arranged between the first locking projection 113 and the second locking projection 114. Therefore, in order to enable the condensation plate to still be used normally when the connecting plate 122 is rotated and arranged between the first locking projection 113 and the second locking projection 114, the interval between the first locking projection 113 and the second locking projection 114 along the axial direction of the guiding column 112 is greater than the thickness of the connecting plate 122.

[0084] In this embodiment, the interval between the first locking projection 113 and the second locking projection 114 along the axial direction of the guiding column 112 is slightly larger than the thickness of the connecting plate 122. Further, to reduce the friction between the connecting plate 122 and the guiding column 112, grease can be applied between the guiding column 112 and the connecting plate 122.

[0085] Please refer to Figure 2 , in some embodiments, a third guiding portion 1121 is provided on the side of the guiding column 112 away from the connecting plate 122.

[0086] In this way, the third guiding portion 1121 can be used to guide the guiding column 112 to be inserted into the locking hole 123, facilitating the disassembly and assembly of the connecting component 10.

[0087] Specifically, the side of the guiding column 112 away from the connecting plate 122 is the free end, and the third guiding portion 1121 is provided on the free end.

[0088] The third guiding part 1121 is frustum-shaped. Further, a transition fillet is provided at the connection between the top surface and the side surface of the third guiding part 1121, and a transition fillet is also provided at the edge corner of the connection between the third guiding part 1121 and the guiding column 112.

[0089] In some embodiments, the connecting part 111 includes a connected support plate 1111 and a fixing plate 1112. The fixing plate 1112 is used to connect with the first component 20. The guiding column 112 is connected with the support plate 1111. The connecting part 111 further includes a reinforcing rib 1113. One end of the reinforcing rib 1113 is connected with the support plate 1111, and the other end of the reinforcing rib 1113 is connected with the fixing plate 1112.

[0090] In this way, it is beneficial to improve the structural strength of the support 11, beneficial to improve the service life of the support 11, and reduce the maintenance cost of the support 11.

[0091] Specifically, the support plate 1111 is arranged at one side edge of the fixing plate 1112. The support plate 1111 is perpendicular to the fixing plate 1112, and the guiding column 112 is perpendicular to the support plate 1111. In this embodiment, the reinforcing rib 1113 is right-angled triangle-shaped. One right-angled side of the reinforcing rib 1113 is connected with the support plate 1111, and the other right-angled side of the reinforcing rib 1113 is connected with the fixing plate 1112. Transition fillets are provided at the edges and corners of the support plate 1111 and the fixing plate 1112.

[0092] Further, a long slot is formed on the mounting plate. The width of the long slot is slightly larger than the thickness of the fixing plate 1112, and the length of the long slot is slightly larger than the length of the fixing plate 1112. During installation, the fixing plate 1112 passes through the long slot and is fixed on the back surface of the mounting plate.

[0093] Limit parts are also provided on both sides of the connection between the support plate 1111 and the fixing plate 1112. Both ends of the limit parts abut against both ends of the long slot to prevent the support plate 1111 from sliding in the long slot.

[0094] The fixing holes are arranged on the fixing plate 1112. The number of the fixing holes is two. When the mounting plate is installed with the condensation plate, the distance between the fixing hole farther from the condensation plate and the support plate 1111 is greater than the distance between the fixing hole closer to the condensation plate and the support plate 1111.

[0095] In other embodiments, to avoid stress concentration, the reinforcing rib 1113 can also be set as trapezoid-shaped. The two side edges of the reinforcing rib 1113 are perpendicular. One side edge of the reinforcing rib 1113 is connected with the support plate 1111, and the other side edge of the reinforcing rib 1113 is connected with the fixing plate 1112.

[0096] Please refer to Figure 4 , in some embodiments, the number of the lock holes 123 is two, and the two lock holes 123 are arranged at both ends of the connecting plate 122.

[0097] In this way, both ends of the bracket 12 can be quickly disassembled and assembled with the support 11, which is beneficial for the bracket 12 to adapt to more installation scenarios.

[0098] Specifically, the connecting plate 122 is connected to one side edge of the installation part 121. Two locking holes 123 are arranged at both ends of the connecting plate 122, and the two locking holes 123 are symmetric about the midline of the installation part 121. In this way, when the bracket 12 is connected to the condensation plate, the bracket 12 located on the left edge of the condensation plate can set the installation part 121 on the right side of the connecting plate 122 to be connected to the condensation plate, and the bracket 12 located on the right edge of the condensation plate can set the installation part 121 on the left side of the connecting plate 122 to be connected to the condensation plate, so that the bracket 12 can adapt to more different installation scenarios.

[0099] In some embodiments, the number of supports 11 is two. The two supports 11 are arranged at intervals on the first component 20. The axes of the two guide columns 112 are on the same straight line. The number of brackets 12 is two. The two brackets 12 are arranged at intervals on the second component 30. The brackets 12 and the supports 11 are arranged in one-to-one correspondence.

[0100] In this way, the cooperation of the two supports 11 and the brackets 12 is beneficial to improving the reliability of the detachable rotational connection between the first component 20 and the second component 30.

[0101] Specifically, in this embodiment, the two brackets 12 are respectively arranged at two side edges of the condensation plate. The two supports 11 respectively cooperate with the two brackets 12 and are arranged in one-to-one correspondence. The guide column 112 serves as the rotation axis of the condensation plate. To ensure that the condensation plate can rotate normally, the axes of the two guide columns 112 are on the same straight line, so that the condensation plate has only one rotation axis.

[0102] In other embodiments, other numbers of supports 11 can also be set. The axes of the guide columns 112 of all brackets 12 should be on the same straight line. The number of brackets 12 is the same as that of supports 11. The brackets 12 and the supports 11 are arranged in one-to-one correspondence.

[0103] Please refer to Figure 1 , in some embodiments, the guide columns 112 of the two supports 11 face the same side.

[0104] In this way, it is convenient for the quick disassembly and assembly between the first component 20 and the second component 30.

[0105] Specifically, the two supports 11 are exactly the same in terms of model size, shape, etc. The guide columns 112 of the two supports 11 face the same side. During installation, the two connecting plates 122 on the condensation plate are respectively sleeved onto the guide columns 112 from the same direction, and through rotation and translation, so that the two connecting plates 122 can be detachably and rotationally arranged between the second locking protrusion 114 and the connecting part 111.

[0106] In other embodiments, the two guide posts 112 can also be arranged in opposite directions. At this time, the distance from the end of one guide post 112 to the root of the other guide post 112 should be slightly less than the distance between the two connecting plates 122, and the first locking protrusion 113 of any one guide post 112 should face the same direction as the second locking protrusion 114 of the other guide post 112. During installation, the connecting plate 122 on one side should be locked between the second locking protrusion 114 and the connecting portion 111 first, and then the guide post 112 on the other side should be inserted into the connecting plate 122 on the other side. By rotating and translating, the connecting plates 122 on both sides can be detachably and rotatably arranged between the first locking protrusion 113 and the second locking protrusion 114.
