Description

Technical Field

[0001] The utility model relates to the technical field of power cabinets, in particular to a shutter and a cabinet. Background Art

[0002] A power chassis is typically a box structure used to house electrical equipment, such as transformers, switchgear, and control panels. Its design must take into account equipment safety, heat dissipation, and environmental adaptability. The design of a power chassis typically incorporates air ducts to dissipate heat from the chassis.

[0003] However, dust or water can easily enter the cabinet through the air outlet duct, damaging the electrical components inside. To prevent dust or water from entering the cabinet, shutters are typically installed in the air outlet duct to block dust or water. However, existing shutters are still relatively ineffective in blocking dust and water, making them difficult to meet the requirements of power boxes and other structures. Utility Model Content

[0004] The main purpose of the present invention is to provide a shutter and a cabinet, so as to at least solve the problem that the shutters in the related art have relatively poor waterproof and dustproof effects.

[0005] According to one aspect of the present invention, a shutter is provided, comprising:

[0006] A bracket, wherein a mounting cavity is provided on the bracket;

[0007] a blade assembly comprising a plurality of blades, the plurality of blades being sequentially spaced apart in the mounting cavity along a height direction of the bracket, with ends of two adjacent blades being nested to enclose and form a curved air guide channel;

[0008] A flow guide component is installed at the bottom of the installation cavity, and the flow guide component is located on a first side of the blade assembly, so as to at least guide dust and / or liquid at the bottom of the installation cavity to a second side of the blade assembly opposite to the first side.

[0009] Furthermore, the blade is bent and surrounded to form a first recessed portion and a second recessed portion, wherein the first recessed portion and the second recessed portion are recessed in opposite directions and are sequentially arranged along the height direction;

[0010] Among the two adjacent blades, the end of the first blade close to the second blade is inserted into the first recessed portion of the second blade, and the end of the second blade close to the first blade is inserted into the second recessed portion of the first blade, so as to form the curved air guide channel between the two adjacent blades.

[0011] Furthermore, the cross-sectional area of the blade is S-shaped.

[0012] Furthermore, the guide component includes a supporting portion and a guide portion, the supporting portion is arranged on a first side of the blade assembly, and the guide portion is arranged on a side of the supporting portion close to the blade assembly to at least guide dust and / or liquid at the bottom of the mounting cavity to the outside of the bracket.

[0013] Further, the support portion includes a support plate, and the support plate is spaced apart from the blade assembly by a predetermined gap.

[0014] Furthermore, the predetermined gap is 20 mm to 40 mm.

[0015] Furthermore, the guide portion includes a first guide member, both ends of which are respectively connected to the bottom end of the support portion and the bottom end of the bracket, and the bottom end of the support portion is higher than the bottom surface of the installation cavity so that the first guide member is tilted.

[0016] Furthermore, the blade located at the bottom of the mounting cavity is a terminal blade, and the guide portion further includes a second guide member, which is connected to a side of the support portion close to the blade assembly and is located above the first guide member, and the second guide member is inclined toward the bottom of the mounting cavity and inserted into the first recessed portion of the terminal blade, and a gap is formed between the second guide member and the inner wall surface of the first recessed portion; and / or,

[0017] The bottom of each blade is provided with an inclined portion, and the inclined portion is inclined toward the bottom of the installation cavity.

[0018] On the other hand, the present application also mentions a cabinet, which includes side panels and shutters, wherein the side panels are provided with mesh holes, the shutters are the above-mentioned shutters, the shutters are installed on the side panels through the brackets, and the blade assembly covers the surface of the mesh holes.

[0019] Furthermore, the cabinet further includes a sealing layer, which is located in the gap between the bracket and the side panel and extends along the outer circumference of the installation cavity.

[0020] In the present invention, the multiple blades of the blade assembly are spaced apart along the height direction of the bracket and can be arranged around to form a curved air guide channel. When the shutters in this application are installed on other structures, such as the side panels of a cabinet, water or other fluids or dust need to bypass the curved air guide channel to enter the interior of the cabinet. In other words, the setting of the curved air guide channel can play a certain role in hindering water or dust, and can prevent water or dust from entering the interior of the cabinet to a certain extent. In addition, the first side of the blade assembly in this application has a guide component. When water or dust accidentally enters the first side of the blade assembly, the guide component can be used to guide the water or dust entering the first side of the blade assembly to the second side of the blade assembly opposite to the first side. In this way, it is convenient to guide the water or dust inside the installation cavity to the outside of the shutter.

[0021] Compared with existing Venetian blinds, the Venetian blinds of the present application can solve the problem of poor waterproof and dustproof effects of Venetian blinds in related technologies by forming a curved air guide channel in the installation cavity and setting a guide component at the bottom of the installation cavity.

It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0031] See also Figures 1 to 3 As shown, according to an embodiment of the present invention, a shutter is provided, which includes a bracket 10, a blade assembly 20 and a flow guide component 30.

[0032] The bracket 10 is provided with a mounting cavity 11. The blade assembly 20 includes a plurality of blades 21, which are sequentially spaced apart in the mounting cavity 11 along the height direction of the bracket 10. The ends of two adjacent blades 21 are nested to enclose a curved air guide channel 50. A flow guide component 30 is installed at the bottom of the mounting cavity 11. The flow guide component 30 is located on a first side of the blade assembly 20 (the first side specifically refers to the side of the blade assembly 20 facing away from the side panel 40 after the blinds are installed on other structures, such as the side panel 40), so as to at least guide dust and / or liquid at the bottom of the mounting cavity 11 to a second side of the blade assembly 20 opposite to the first side.

[0033] In the present invention, the bracket 10 can be formed by connecting multiple plates or directly from a single plate through a process such as stamping. The blade assembly 20 can be composed of two blades 21, or two, three, or more blades 21. In this embodiment, the bracket 10 is formed by welding multiple plates, and the blade assembly 20 is composed of five blades 21.

[0034] In the present application, the multiple blades 21 of the blade assembly 20 are spaced apart along the height direction of the bracket 10 and can enclose a curved air guide channel 50. When the shutter of this embodiment is installed on other structures, such as the side panels 40 of a cabinet, water or other fluids or dust must bypass the curved air guide channel 50 to enter the interior of the cabinet. In other words, the provision of the curved air guide channel 50 can provide a certain barrier to water or dust, thereby preventing water or dust from entering the cabinet. In addition, the first side of the blade assembly 20 of this embodiment (the side facing away from the side panels 40) has a guide member 30. If water or dust accidentally enters the first side of the blade assembly 20, the guide member 30 can guide the water or dust entering the first side of the blade assembly 20 to the second side of the blade assembly 20 (i.e., the side closer to the side panels 40), thereby conveniently guiding the water or dust inside the installation cavity 11 to the exterior of the shutter.

[0035] That is to say, compared with the existing Venetian blinds, the Venetian blinds of the present application can solve the problem of poor waterproof and dustproof effects of the Venetian blinds in the related art by forming a curved air guide channel 50 in the installation cavity 11 and at the same time providing a guide component 30 at the bottom of the installation cavity 11.

[0036] Further, see Figure 1 and Figure 2 As shown, in order to form a curved air guide channel 50, the blades 21 in this embodiment are bent to form a first recessed portion 211 and a second recessed portion 212. The first recessed portion 211 and the second recessed portion 212 are recessed in opposite directions and are arranged sequentially along the height direction. In two adjacent blades 21, the end of the first blade 21 close to the second blade 21 is inserted into the first recessed portion 211 of the second blade 21, and the end of the second blade 21 close to the first blade 21 is inserted into the second recessed portion 212 of the first blade 21. In this way, a curved air guide channel 50 can be formed between the two adjacent blades 21, thereby preventing water or dust from entering the first side of the blade assembly 20 to a certain extent.

[0037] Specifically, the cross-sectional area of the blade 21 in this embodiment is S-shaped. It can be understood that the cross-sectional area refers to the cross-sectional area obtained by cutting the blade 21 along the height direction of the bracket 10. In the present application, the cross-sectional area of the blade 21 can be an angular S-shape or a smooth S-shape.

[0038] This application Figures 1 to 3The shape of the blade 21 with distinct edges and corners is shown in FIG. Specifically, the blade 21 includes a first vertical section 214, a second vertical section 215, a first bent section 216, a second bent section 217, and an inclined portion 213. The first vertical section 214 and the second vertical section 215 both extend in the height direction of the bracket 10. The upper end of the first vertical section 214 is provided with a first bent section 216. The angle between the first bent section 216 and the first vertical section 214 can be an acute angle, a right angle, or an obtuse angle. This embodiment shows that the angle between the first bent section 216 of the blade 21 located at the top of the mounting cavity 11 and the first vertical section 214 is a right angle, while the angles between the first bent sections 216 and the first vertical sections 214 of the remaining blades 21 are acute angles. The lower end of the first vertical section 214 is provided with a second bent section 217. The angle between the second bent section 217 and the first vertical section 214 can be acute, right, or obtuse. This embodiment shows a case where the angle between the second bent section 217 and the first vertical section 214 of the blade 21 is obtuse. The upper end of the second bent section 217 is connected to the lower end of the first vertical section 214. The lower end of the second bent section 217 is provided with a second vertical section 215. The lower end of the second bent section 217 is connected to the upper end of the second vertical section 215, and the angle between the second bent section 217 and the second vertical section 215 is obtuse. The lower end of the second vertical section 215 is provided with an inclined portion 213. The upper end of the inclined portion 213 is connected to the lower end of the second vertical section 215, and the angle between the inclined portion 213 and the second vertical section 215 is obtuse. The first bent section 216, the first vertical section 214, and the second bent section 217 enclose a second recessed portion 212, while the second bent section 217, the second vertical section 215, and the inclined portion 213 enclose a first recessed portion 211. The first and second recessed portions 211 and 212 are recessed in opposite directions and are arranged sequentially along the height direction. The first recessed portion 211 is located below the second recessed portion 212. Furthermore, the opening of the first recessed portion 211 faces the first side of the blade assembly 20, while the opening of the second recessed portion 212 faces away from the first side of the blade assembly 20. The blades 21 having the above-described characteristics are nested and spaced apart along the height direction of the bracket 10. Adjacent blades 21 must meet the following requirements: starting from the bottom of the mounting cavity 11, the first bent section 216 of the first blade 21 is partially inserted into the first recessed portion 211 of the second blade 21, and the inclined portion 213 of the second blade 21 is partially inserted into the second recessed portion 212 of the first blade 21. Adjacent blades 21 are arranged along the height direction of the bracket 10 from the bottom of the installation cavity 11 to the top of the installation cavity 11 in the above manner, so that a curved air guide channel 50 can be formed between two adjacent blades 21.

[0039] Further, see Figure 1As shown, the guide component 30 includes a support portion 31 and a guide portion 32, the support portion 31 is arranged on a first side of the blade assembly 20, and the guide portion 32 is arranged on a side of the support portion 31 close to the blade assembly 20 to at least guide dust and / or liquid at the bottom of the blind to a second side of the blade assembly 20 opposite to the first side.

[0040] For example, the support portion 31 and the guide portion 32 can be integrally formed or separately formed. When the support portion 31 and the guide portion 32 are integrally formed, the support portion 31 and the guide portion 32 can be turned from a single piece of material, or can be formed using a processing method such as injection molding and stamping. When the support portion 31 and the guide portion 32 are separately formed, the support portion 31 and the guide portion 32 can be processed separately, and then the support portion 31 and the guide portion 32 can be connected and fixed together, and the connection between the support portion 31 and the guide portion 32 can be connected by bonding, welding, snap-fit connection, etc.

[0041] Further, see Figure 1 As shown, the support portion 31 includes a support plate 311, and a predetermined gap 312 is set between the support plate 311 and the blade assembly 20. The support plate 311 can be a flat plate, or a regular or irregular plate such as an arc-shaped plate. This embodiment shows the situation when the support plate 311 is a flat plate. The present application sets a predetermined gap 312 between the support plate 311 and the blade assembly 20. In this way, dust or water entering from the second side of the blade assembly 20 to the first side will fall onto the guide component 30 at the bottom of the installation cavity 11 under the action of its own gravity during the transmission process within the predetermined gap 312, and will eventually be discharged from the blinds by being diverted to the second side of the blade assembly 20 opposite to the first side.

[0042] Further, see Figure 1 As shown, the width D of the predetermined gap 312 is 20 mm to 40 mm. If the width D of the predetermined gap 312 is greater than 40 mm, the overall size of the shutter will be larger. The shutter of the present application is installed inside the cabinet, so it will occupy too much space inside the cabinet, thereby reducing the available space inside the cabinet, which is not conducive to the installation of other components inside the cabinet (not shown). If the width D of the predetermined gap 312 is set to less than 20 mm, it will be difficult for the guide component 30 to collect dust and / or liquid that enters the cabinet through each air guide channel 50. The dust and / or liquid that enters the cabinet through each air guide channel 50 will affect the normal operation of the cabinet. Even when too much dust and / or liquid enters the cabinet, it will damage other components inside the cabinet. In serious cases, it may cause a fire, which is not conducive to protecting people's lives and property safety.

[0043] Further, see Figure 1 As shown, the guide portion 32 includes a first guide member 321, the two ends of which are respectively connected to the bottom end of the support portion 31 and the bottom end of the bracket 10, and the bottom end of the support portion 31 is higher than the bottom surface of the installation cavity 11 so that the first guide member 321 is tilted.

[0044] Exemplarily, the first air guide 321 can be a flat plate, or a regular or irregular plate such as an arc-shaped plate. This embodiment illustrates the case where the first air guide 321 is a flat plate. In the present application, the bottom end of the support portion 31 is higher than the bottom surface of the mounting cavity 11, so that the first air guide 321 is tilted. The tilted configuration of the first air guide 321 can facilitate the discharge of dust and / or liquid that enters the cabinet through the various air guide channels 50 to the exterior of the bracket 10. If the bottom end of the support portion 31 is lower than or parallel to the bottom surface of the mounting cavity 11, dust and / or liquid that enters the cabinet through the various air guide channels 50 will accumulate on the first air guide 321. In severe cases, the air guide channels 50 located at the bottom of the mounting cavity 11 may be blocked. If excessive dust and / or liquid accumulates, they may enter the cabinet where other components are mounted, thereby affecting the normal operation of the cabinet.

[0045] Further, see Figure 1 As shown, the blade 21 located at the bottom of the installation cavity 11 is the end blade 21a, and the guide portion 32 also includes a second guide member 322, which is connected to the side of the support portion 31 close to the blade assembly 20 and is located above the first guide member 321, and the second guide member 322 is inclined toward the bottom of the installation cavity 11 and inserted into the first recessed portion 211 of the end blade 21a, and there is a gap 323 between the second guide member 322 and the inner wall surface of the first recessed portion 211; and / or, an inclined portion 213 is provided at the bottom of each blade 21, and the inclined portion 213 is inclined toward the bottom of the installation space.

[0046] For example, the second flow guide 322 and the support portion 31 can be integrally formed or separately formed. When the second flow guide 322 and the support portion 31 are integrally formed, the second flow guide 322 and the support portion 31 can be turned from a single piece of material, or can be formed using a processing method such as injection molding or stamping. When the second flow guide 322 and the support portion 31 are separately formed, the second flow guide 322 and the support portion 31 can be processed separately, and then the second flow guide 322 can be connected and fixed to the upper end of the support portion 31 and on a side close to the blade assembly 20. The connection between the second flow guide 322 and the support portion 31 can be achieved by bonding, welding, snap-fit connection, or other connection methods. This embodiment illustrates a case where the second flow guide 322 and the support portion 31 are separately formed and connected by welding. The second guide member 322 is primarily designed to prevent dust and / or liquid from entering the cabinet through the air guide channel 50 at the bottom of the mounting cavity 11 during operation, thereby affecting the normal operation of the cabinet. The second guide member 322 effectively blocks dust and / or liquid, thereby effectively protecting the components within the cabinet (not shown). Furthermore, the second guide member 322 is configured as described above, and the cooperation between the end blades 21a and the second guide member 322 not only blocks dust and / or liquid, but also directs dust and / or liquid that enters the cabinet through the various air guide channels 50 to the exterior of the bracket 10. It should be noted that: when the second air guide member 322 is partially inserted into the first recessed portion 211 of the end blade 21a, it is necessary to ensure that there is a gap 323 between the lower end portion of the second air guide member 322 and the inner wall surface of the first recessed portion 211. The setting of the gap 323 can not only allow the air guide channel 50 at the bottom of the installation cavity 11 to pass through, but also further prevent dust and / or liquid from entering the air guide channel 50 at the bottom of the installation cavity 11 to the location where the remaining components are installed in the cabinet. Therefore, the gap 323 can further protect the remaining components in the cabinet.

[0047] Further, see Figure 2 As shown, the present application also provides a cabinet, which includes a side panel 40 and a shutter, and a mesh 41 is provided on the side panel 40. The shutter is the shutter in the above embodiment. The shutter is installed on the side panel 40 through a bracket 10, and the blade assembly 20 covers the surface of the mesh 41.

[0048] Exemplarily, the mesh 41 and the side panel 40 can be an integrally formed arrangement or a separately formed arrangement. This embodiment shows a case where the mesh 41 and the side panel 40 are integrally formed. In other embodiments of the present application, a worker can set the mesh 41 on a single plate, and then install the plate provided with the mesh 41 at a position where ventilation and heat dissipation vents are provided on the side panel 40. The arrangement of the mesh 41 can first block dust and / or liquids in the first step, and the dust and / or liquids that the mesh 41 fails to block can be blocked in the second step by the louvers installed on the side panel 40, so that the cabinet can be well protected. The connection between the louvers and the side panel 40 of the cabinet can be by welding, bonding, bolting, or other connection methods. This embodiment shows a case where the louvers are fixed to the side panel 40 of the cabinet by bolting.

[0049] Further, see Figure 2 As shown, the cabinet further includes a sealant layer (not shown) located within the gap between the bracket 10 and the side panel 40 and extending along the outer periphery of the mounting cavity 11. The sealant layer is provided to prevent dust and / or liquid from entering the cabinet through the gap at the connection between the bracket 10 and the side panel 40 and into the locations where other components are mounted, thereby further protecting the cabinet.

[0050] From the above statements, it can be known that the present application can solve the problem of poor waterproof and dustproof effects of the shutters in the related art by providing a shutter and a cabinet composed of a bracket 10, a blade assembly 20, a guide component 30 and a cabinet. During assembly, first, a plurality of bracket plates are used to enclose a mounting cavity 11, and the bracket plates are connected and fixed by welding to form a bracket 10. Secondly, the five blades 21 are arranged in the mounting cavity 11 in sequence along the height direction of the bracket 10. Starting from the bottom of the mounting cavity 11, the first bent section 216 of the first blade 21 is partially inserted into the first recessed portion 211 of the second blade 21, and the inclined portion 213 of the second blade 21 is partially inserted into the second recessed portion 212 of the first blade 21. Adjacent blades 21 are arranged in the above manner along the height direction of the bracket 10 from the bottom of the mounting cavity 11 to the top of the mounting cavity 11, thereby forming a curved air guide channel 50 between two adjacent blades 21, and each blade 21 is mounted and fixed to the bracket 10. Then, the air guide component 30 is installed at the bottom of the mounting cavity 11 from the first side of the blade assembly 20, and the second air guide member 322 of the air guide component 30 is partially inserted into the first recessed portion 211 of the terminal blade 21, ensuring that a gap 323 is formed between the lower end of the second air guide member 322 and the inner wall surface of the first recessed portion 211. The gap 323 is configured to allow the air guide channel 50 at the bottom of the mounting cavity 11 to pass through and further prevent dust and / or liquid from entering the location where other components are installed in the cabinet through the air guide channel 50 at the bottom of the mounting cavity 11. Finally, the assembled shutters are installed on the side panels 40 of the cabinet at the positions where the ventilation holes are provided. The ventilation holes are provided with mesh holes 41 to perform the first step of blocking dust and / or liquid. The shutters then perform the second step of blocking the dust and / or liquid that the mesh holes 41 fail to block. The dust and / or liquid that enters the cabinet from the ventilation holes can be guided to the bottom of the shutters through the shutters, and the dust and / or liquid at the bottom of the shutters can eventually be guided to the outside of the cabinet through the guide component 30.

[0051] It can be seen that the shutters and cabinets of the present application are designed by optimizing the structure of the shutters on the basis of the existing technology, and a guide component 30 is provided at the bottom of the installation cavity 11 and close to the first side of the blade assembly 20. The guide component 30 can guide the dust and / or liquid at the bottom of the shutters to the outside of the cabinet, thereby solving the problem of poor waterproof and dustproof effects of the shutters in the related art.

[0052] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0053] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
