Description

Technical Field

[0001] The utility model relates to a fixed or movable closing device used for openings of buildings, vehicles, fences or similar surrounding objects, in particular to a shutter and an electrical cabin using the shutter. Background Art

[0002] In the prior art, the ventilation windows of energy storage cabins and prefabricated cabins used in energy storage power stations and substations are usually sheet metal welded structures. When assembling the ventilation windows, the louver blades of the ventilation windows usually need to be manually positioned and then welded, which results in low processing efficiency and high labor intensity. When assembling the ventilation windows by snap-fitting, the louver blades may slide in the slots, thereby affecting the structural stability of the entire ventilation window.

[0003] In the invention patent with authorization announcement number AT405077B, if Figure 1 As shown, the ventilation window is assembled in a snap-fit ​​manner, including a column unit 2, which includes a column 1, and the column has an extension portion 3. The louver blades 6 are snapped into the slots 5 provided on the column 1, and then an L-shaped profile 4 with a groove 8 that can be matched with the slot 5 is used to fix the louver blades 6 on the column 1. At the same time, the buckle 7 on the L-shaped profile 4 is snapped into the buckle 7 on the column 1, thereby fixing the L-shaped profile 4 on the column 1, thus completing the assembly of the entire shutter. However, during use, the louver blades 6 are prone to slide between the slots 5 and the grooves 8, causing the L-shaped profile 4 to deform at its slot 5, and then causing one end of the louver blade 6 to fall out of the column 1, affecting the overall structure of the shutter. Utility Model Content

[0004] The purpose of the present utility model is to provide a shutter to solve the technical problem of poor structural stability of existing shutters; at the same time, the purpose of the present utility model is also to provide an electrical cabin using the shutter to solve the technical problem of safety accidents caused by damage to the shutter in the existing electrical cabin.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions for a shutter:

[0006] A Venetian blind comprises a window frame and blades, wherein the window frame comprises left and right columns, the columns comprise a core column and a gusset plate fastened to the outside of the core column, the two ends of the blades are inserted into mounting grooves provided in the core column in an oblique downward direction, the gusset plate closes the notch of the mounting groove through the inner side surface of the corresponding side, and a clearance opening is provided on the inner side of the gusset plate for circumventing the blades.

[0007] The beneficial effect of the above technical solution is that the technical solution of the shutter of the present invention is an element-changing invention. Specifically, since the assembly of the shutter structure by welding requires manual positioning, the assembly efficiency is low and the labor intensity is high. The present invention inserts the blades into the mounting grooves on the core column in an oblique downward direction by insertion. After the blades and the core column are assembled by insertion, the core column is wrapped with a buckle plate. At this time, the inner surface of the corresponding side of the buckle plate can close the notch of the mounting groove, so that the blades can be stably placed in the mounting groove on the core column. Even if the blades are affected by external factors during use and have a tendency to move toward the notch of the mounting groove, since the inner surface of the buckle plate closes the notch of the mounting groove and has higher strength, the blades will not fall out of the notch of the mounting groove due to the blocking of the buckle plate, thereby greatly improving the structural stability of the entire shutter.

[0008] Furthermore, the gusset plate is divided into at least two sections along its length, and adjacent sections are detachably connected. Advantageous Effect: The gusset plate is divided into at least two sections along its length, and adjacent sections are detachably connected. When a single blade is damaged, the detachable connection between the adjacent sections of the gusset plate facilitates the removal of the gusset plate, thereby facilitating the replacement of the damaged blade.

[0009] Furthermore, the ends of the gusset plates of the two columns are connected through corresponding cross beams of the window frame.

[0010] Beneficial effect: Using a crossbeam to connect the ends of the gusset plates of the two columns can further increase the structural strength of the shutter and improve the structural stability of the shutter.

[0011] Furthermore, adjacent ends of adjacent sections of the gusset plate are respectively provided with outer flanges, and are detachably connected by cooperating with corresponding fasteners through the outer flanges.

[0012] Beneficial effect: Providing outer flanges at adjacent ends of adjacent sections of the gusset plate can provide installation space for fasteners and facilitate the disassembly and assembly of the gusset plate.

[0013] Furthermore, the blades are inserted into corresponding mounting grooves through protruding lugs provided at their ends.

[0014] Beneficial effect: The blade is inserted into the installation slot through the ear plate provided at the end rather than directly through the end of the blade, so that the end surface of the part of the blade end where the ear plate is not provided can be blocked by the core column, preventing the blade from sliding between the two core columns along the length direction of the blade, thereby ensuring the stability of the blade after installation.

[0015] Furthermore, the ear plates of at least a portion of the blades are provided with folded edges that engage with the outer side surfaces of the corresponding core columns along the length direction of the blades.

[0016] Furthermore, the blades with folded edges on the ear plates and the blades without folded edges on the ear plates are alternately arranged along the length direction of the column.

[0017] Furthermore, the gusset plate is an L-shaped gusset plate, and the outer side surface of the core column is fixedly connected to the corresponding gusset plate.

[0018] Furthermore, the gusset plate and the core column are fixedly connected by fasteners.

[0019] Beneficial effect: The gusset plate and the core column are connected using fasteners, which further increases the structural strength and stability of the entire shutter.

[0020] To achieve the above purpose, the electrical compartment of the present utility model adopts the following technical solutions:

[0022] The beneficial effect of the above technical solution is that the utility model is an invention based on the element change of the technical solution of the existing electrical cabin. Specifically, the shutters used in the existing electrical cabin are completed by welding. The assembly of the shutter structure requires manual positioning, and the assembly efficiency is low and the labor intensity is high. The shutters used in the electrical cabin of the utility model are inserted into the installation grooves on the core column in an insertion manner. After the blades and the core column are inserted and combined, the core column is wrapped with a buckle plate. At this time, the inner surface of the corresponding side of the buckle plate can close the notch of the installation groove, so that the blades can be stably placed in the installation groove on the core column. Even if the blades are affected by external factors during use and have a tendency to move toward the notch of the installation groove, since the inner surface of the buckle plate closes the notch of the installation groove and has higher strength, the blades will not fall out of the notch of the installation groove due to the blocking of the buckle plate, which greatly improves the structural stability of the entire shutter and avoids safety accidents caused by easy damage to the shutters in the electrical cabin.

[0023] Furthermore, the gusset plate is divided into at least two sections along its length, and adjacent sections are detachably connected. Advantageous Effect: The gusset plate is divided into at least two sections along its length, and adjacent sections are detachably connected. When a single blade is damaged, the detachable connection between the adjacent sections of the gusset plate facilitates the removal of the gusset plate, thereby facilitating the replacement of the damaged blade.

[0024] Furthermore, the ends of the gusset plates of the two columns are connected through corresponding cross beams of the window frame.

[0026] Furthermore, adjacent ends of adjacent sections of the gusset plate are respectively provided with outer flanges, and are detachably connected by cooperating with corresponding fasteners through the outer flanges.

[0027] Beneficial effect: Providing outer flanges at adjacent ends of adjacent sections of the gusset plate can provide installation space for fasteners and facilitate the disassembly and assembly of the gusset plate.

[0028] Furthermore, the blades are inserted into corresponding mounting grooves through protruding lugs provided at their ends.

DETAILED DESCRIPTION

[0049] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0050] The technical concept of the shutter of the present utility model is as follows:

[0051] In the prior art, when assembling blinds, welding is used to assemble blades and window frames, which requires manual positioning, is time-consuming and labor-intensive. However, when plugging blades and window frames into one assembly, new problems arise. For example, the blades are easily displaced in the window frame during use, thereby affecting the overall structural strength and stability of the blinds. When this blind structure is installed on the body of the electrical compartment, safety accidents may occur due to damage to the blind structure.

[0052] Therefore, the present invention inserts the blades into the mounting grooves on the core column in an obliquely downward direction by means of insertion. After the blades and the core column are assembled, a buckle plate is used to wrap the core column. At this time, the inner side surface of the corresponding side of the buckle plate can close the notch of the mounting groove, so that the blades can be stably placed in the mounting grooves on the core column. Even if the blades are affected by external factors during use and tend to move toward the notch of the mounting groove, since the inner side surface of the buckle plate closes the notch of the mounting groove, and compared with the structure in the background technology that the profile blocks the blades through its opening, the inner side surface of the buckle plate has higher strength and a different force angle. The blades are blocked by the buckle plate and will not fall out of the notch of the mounting groove, thereby greatly improving the structural stability of the entire blinds.

[0053] Based on the above technical concept, the embodiments of the shutters described in the present invention are as follows:

[0054] like Figure 2-8 As shown, the shutter includes a window frame, which includes a crossbeam 16 and columns on the left and right sides. The left column includes a left core column 12, and the right column includes a right core column 11. The cross-sections of the left core column 12 and the right core column 11 are both T-shaped. A plurality of oblique mounting grooves 20 and a plurality of fastener mounting holes are provided on the inner bent plates 30 of the left core column 12 and the right core column 11. The outer bent plates 31 of the left core column 12 and the right core column 11 can be assembled with the crossbeam 16 to form the frame structure of the shutter; the window frame also includes a buckle plate 15, which is buckled on the inner bent plate 30, and the ends of the two buckle plates 15 buckled on the left core column 12 and the right core column 11 are connected by the crossbeam 16, so that the crossbeam 16 and the two buckle plates 15 form a U-shaped structure as a whole.

[0055] like Figure 4-6As shown, the shutters also include blades, the ends of which are provided with ear plates 28 extending and protruding along the length direction of the blades, so that the blades can be inserted into the oblique mounting grooves 20 provided on the left core column 12 and the right core column 11 through the ear plates 28 in an oblique downward direction. The blades include a first blade 13 and a second blade 14. The end of the second blade 14 is not only protruding with an ear plate 28, but also a folded edge 29 is provided at the end of the ear plate 28 away from the blade body. The second blade 14 can be stopped and matched with the outer side surface of the inner bending plate 30 of the left core column 12 and the right core column 11 along the length direction of the blade through the folded edge 29, so that the second blade 14 is not easy to fall out of the left core column 12 and the right core column 11 along the length direction of the blade; and when inserting the blades, the first blade 13 and the second blade 14 are alternately arranged along the length direction of the left core column 12 and the right core column 11.

[0056] like Figure 8-10 As shown, each gusset plate 15 is divided into two sections along its length direction, and adjacent ends of adjacent sections are respectively provided with outer flanges 17, and fastener mounting holes are provided on the outer flanges 17, which are specifically pin holes. The two adjacent sections are fixedly connected by the pin holes provided on the outer flanges 17 and the use of pin shafts, and the inner side of the gusset plate 15 is also provided with a avoidance opening for avoiding the blades; when the gusset plate 15 is buckled on the inner bent plate 30, the gusset plate 15 can close the notch of the mounting groove 20 on the inner bent plate 30 through the inner side surface of its corresponding side, that is, the gusset plate 15 can seal the blade inserted in the mounting groove 20 in the mounting groove 20 through the inner side surface of its corresponding side, thereby preventing the blade from falling out of the notch of the mounting groove 20 during the use of the blinds.

[0057] Of course, as a preferred embodiment, the single buckle plate 15 can also be a whole, buckled on the inner bending plate 30; the buckle plate 15 can also be divided into multiple sections along its length, and adjacent sections are fixedly connected to the pin shaft through the pin holes set on the outer flange 17.

[0058] like Figure 8-10 As shown, the cross-section of the gusset plate 15 is L-shaped, and the gusset plate 15 is also provided with a plurality of fastener mounting holes along its length direction. When the gusset plate is buckled onto the inner bent plate, the fastener mounting holes on the gusset plate correspond one-to-one to the fastener mounting holes on the inner bent plate, and then the corresponding fasteners are used to fix the gusset plate and the inner bent plate through the fastener mounting holes. In this embodiment, the fasteners are specifically blind rivets, and the fastener mounting holes are rivet holes 19; of course, in other embodiments, the fasteners can also be screws, bolts, etc., and the fastener mounting holes are threaded holes.

[0059] like Figure 8 、 10As shown, the crossbeam 16 includes an upper crossbeam and a lower crossbeam. A latch mounting hole 18 is provided on the outer end face of the upper crossbeam, and a spring latch 21 is installed in the latch mounting hole 18; a threaded hole is also provided at the lower end of the gusset plate 15, and a bolt 22 passes through the threaded hole and is then fixed to the lower end of the gusset plate by a nut 23.

[0060] The embodiment of the electrical compartment described in the utility model is:

[0061] like Figure 11-13 As shown, the electrical cabin 32 includes a cabin body, on which a ventilation window 33 is provided. The ventilation window 33 includes a mounting plate 24 and a waterproof plate 25. The mounting plate 24 and the waterproof plate 25 are welded to form a shutter mounting frame; pin shaft fixing frame plates 26 are symmetrically provided on both sides of the upper end of the waterproof plate 25, and waist-shaped pin shaft through holes are provided on the pin shaft fixing frame plates 26; rotating base plates 27 are symmetrically provided on both sides of the lower end of the waterproof plate 25, and oblique waist-shaped through holes are provided on the rotating base plates 27.

[0062] like Figure 12 、 13 As shown, the bolts 22 on both sides of the lower end of the shutter are inserted into the waist-shaped oblique through holes of the rotating base plate 27 at the lower end of the shutter mounting frame, and the spring latch 21 is pulled to make it penetrate into the waist-shaped pin shaft through holes of the pin shaft fixing frame plate 26 at the upper end of the shutter mounting frame, and the shutter can be installed on the electrical compartment body. When the shutter is installed on the electrical compartment 32, filter cotton is filled between adjacent blades; when the filter cotton needs to be replaced, the spring latch 21 is pulled to cancel the limit, and the shutter is pulled outward, and the oblique waist-shaped hole stroke characteristics on the rotating base plate 27 are used to rotate the shutter to open, and the filter cotton can be installed and replaced.

[0063] It should be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction.
