The second support arm is provided with a second guide groove, which is connected to the connecting groove. The second guide groove is configured to guide the connecting part on the side wall tarpaulin pulled out by the adjacent support member to move closer to the second side and guide the connecting part to connect to the connecting groove.

[0014] In some embodiments, the top tarpaulin is at least partially connected to the top surfaces of the first support arm and the second support arm; the support stands on the bearing plane, and the bottom surfaces of the first support arm and the second support arm at least partially abut against the bearing plane.

[0015] In some embodiments, the dustproof shed further includes a magnetic suction assembly disposed between the connecting groove and the connecting portion that is connected to the connecting groove, the magnetic suction assembly being configured to magnetically connect the connecting groove and the connecting portion.

[0016] In some embodiments, the dustproof shed further includes a limiting structure disposed between the connecting groove and the connecting part that is connected to the connecting groove, the limiting structure being configured to lock and fix the connecting groove and the connecting part in the use state, and to release the locking and fixing of the connecting groove and the connecting part in the non-use state.

[0017] In some embodiments, the limiting structure includes:

[0018] An elastic locking member is movably connected to at least one side wall of the connecting groove. The elastic locking member is configured to retract when pushed by the connecting portion to allow the connecting portion to be inserted into the connecting groove, and to extend after the connecting portion is inserted into the connecting groove to prevent the connecting portion from disengaging from the connecting groove.

[0019] An unlocking component is connected to the elastic locking component, and the unlocking component is configured to cause the elastic locking component to retract when pulled by an external force, so as to release the restriction on the connecting part.

Detailed Implementation

[0040] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the technical solutions of this utility model will be further described in detail below through specific embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0041] Please see Figures 1 to 2 In some embodiments of this application, a quick-assembly and disassembly dustproof shed is provided. The dustproof shed includes at least three support members 1 and a top tarpaulin 2. Each support member 1 has a first axial side connected by a retracting mechanism 3 (e.g., ...). Figure 4 (As shown) is connected to the sidewall tarpaulin 4 (such as Figure 1 As shown in the diagram, the sidewall tarpaulin 4 is configured to be pulled outward or rolled up towards the first side, and the far end of the sidewall tarpaulin 4 away from the first side is provided with a connecting portion 5 (as shown in the diagram). Figure 3 As shown in the diagram). Each support member 1 has an axially extending connecting groove 14 on its axial second side (as shown in the diagram). Figure 3 As shown in the figure, the first side and the second side between two adjacent support members 1 are arranged opposite to each other, and the connecting groove 14 is configured to be detachably connected to the connecting part 5 on the side wall tarpaulin 4 pulled out by the adjacent support member 1.

[0042] The top tarpaulin 2 is detachably connected to the top of all the support members 1, and the top tarpaulin 2, together with all the support members 1 and all the side wall tarpaulins 4, forms a dust-free working space (not shown).

[0043] The main body of the support member 1 can be configured as a polygonal prism structure with at least three side walls. Each side wall of the polygonal prism constitutes one side of the support member 1. The first side and the second side of the support member 1 can be arranged adjacent to each other or spaced apart. The main body of the support member 1 can also be configured as a cylindrical structure with an arc-shaped side wall. The terms "first side" and "second side" are used to distinguish different areas of the arc-shaped side wall of the support member 1.

[0044] The dustproof canopy of this application has at least three support members 1, but may have three or more; this application does not limit this. The first and second sides of adjacent support members 1 are arranged opposite each other. For example, when the total number of support members 1 is three, the three support members 1 are arranged in a triangle on the bearing plane (not shown). Thus, the first side of the first support member 1 is opposite to the second side of the adjacent second support member 1, the first side of the second support member 1 is opposite to the second side of the adjacent third support member 1, and the first side of the third support member 1 is opposite to the second side of the adjacent first support member 1. Figures 1 to 2As shown, when the total number of support members 1 is four, the four support members 1 are arranged in a quadrilateral shape on the bearing plane. Thus, the first side of the first support member 1 is arranged opposite to the second side of the adjacent second support member 1, the first side of the second support member 1 is arranged opposite to the second side of the adjacent third support member 1, the first side of the third support member 1 is arranged opposite to the second side of the adjacent fourth support member 1, and the first side of the fourth support member 1 is arranged opposite to the second side of the adjacent first support member 1.

[0045] The bearing surface is used to support the dustproof shed. It is generally a flat ground, but it can also be a platform or other supporting structure. This application does not limit it in this regard.

[0046] The connecting part 5 and the connecting groove 14 can be connected by a snap-fit ​​method, or they can be connected detachably by other connection methods. This application does not limit this, as long as the connecting part 5 can be detachably connected to the connecting groove 14.

[0047] The number of support components 1 and the length of the side wall tarpaulin 4 on each support component 1 pulled outward to the first side can be set according to the overall shape of the dustproof shed, or selected according to the actual site conditions, so that the size and shape of the dustproof shed can be adjusted as needed to adapt to different work scenarios.

[0048] To ensure that the top tarpaulin 2, the bearing plane and the upper and lower sides of the side wall tarpaulin 4 are in tight contact after assembly, and to prevent dust from entering the cleanroom through the gaps between the top tarpaulin 2, the bearing plane and the side wall tarpaulin 4, the height of the part of the side wall tarpaulin 4 pulled out in the axial direction of the support member 1 is preferably consistent with the axial length of the support member 1.

[0049] The dustproof shed provided in this application has a side wall tarpaulin 4 connected to the first axial side of the support member 1 via a winding mechanism 3, so that the side wall tarpaulin 4 can be pulled out or rolled up towards the first axial side of the support member 1. The far end of the side wall tarpaulin 4 away from the first side is provided with a connecting part 5, and the second axial side of the support member 1 is provided with a connecting groove 14. The first side and the second side between adjacent support members 1 are arranged opposite to each other, so that the connecting groove 14 can be detachably connected to the connecting part 5 on the side wall tarpaulin 4 pulled out by the adjacent support member 1.

[0050] In actual use, the user manually pulls out the side wall tarpaulin 4 connected to the first axial side of one of the support members 1, and pulls the connecting part 5 at the far end of the side wall tarpaulin 4 to the connecting groove 14 of the other support member 1. The side wall tarpaulin 4 is connected between the two adjacent support members 1 through the connection of the connecting part 5 and the connecting groove 14, thus constructing one side wall of the dustproof shed. This process is repeated until all the side wall tarpaulins 4 pulled out from the first axial side of all the support members 1 are connected to the connecting groove 14 on the adjacent support members 1 through the connecting part 5, thereby enclosing the entire side wall of the dustproof shed through all the support members 1 and the side wall tarpaulins 4. Then, the top tarpaulin 2 is installed on top of all the support members 1, creating a dust-free working space between the top tarpaulin 2 and all the support members 1 and the side wall tarpaulins 4.

[0051] After use, the user can manually separate the connecting part 5 from the connecting groove 14, enabling quick assembly and disassembly between the side wall tarpaulin 4 and the adjacent support member 1, and between the support member 1 and the top tarpaulin 2. This simplifies the installation process of the dustproof shed and saves time during installation and disassembly. After disassembly, the side wall tarpaulin 4 is rolled up towards the first side of the support member 1 by the winding mechanism 3. This reduces the space occupied by storing the side wall tarpaulin 4 separately and avoids problems such as loss or surface dust accumulation caused by separate storage. It saves space, facilitates storage and carrying, and allows for quick assembly and disassembly of the dustproof shed for the next use, improving assembly and disassembly efficiency.

[0052] Please see Figure 4 In some embodiments, each support member 1 has an axially extending storage cavity 13; the winding mechanism 3 includes a roller 31 and a coil spring 32. The roller 31 can be configured as a cylindrical structure and is axially rotatably connected to the storage cavity 13 of the support member 1, so that the roller 31 can rotate relative to the support member 1 about its own central axis. The proximal end of the side wall tarpaulin 4 facing away from the connecting part 5 is fixedly connected to the roller 31, so that the roller 31 can roll up the side wall tarpaulin 4 by rotation. The coil spring 32 can be a spiral spring, elastically connected between the roller 31 and the storage cavity 13. The coil spring 32 is configured to automatically drive the roller 31 to rotate forward to roll up the side wall tarpaulin 4. When the user pulls the side wall tarpaulin 4 outward through the connecting part 5, it drives the roller 31 to rotate in the opposite direction, thereby causing the roller 31 to act on the coil spring 32 to undergo pre-tension deformation and store force. After use, the connecting part 5 separates from the connecting groove 14 to release the restriction on the side wall tarpaulin 4. At this time, the coil spring 32 releases the stored elastic potential energy and generates torque to automatically drive the roller 31 to rotate in the forward direction, thereby winding the side wall tarpaulin 4 into the storage cavity 13 through the roller 31, realizing the automatic winding of the side wall tarpaulin 4.

[0053] The structure of the winding mechanism 3 in this application is relatively simple and low in cost, and it realizes the automatic winding of the side wall tarpaulin 4, which facilitates the disassembly and assembly of the dustproof shed.

[0054] Preferably, the side wall tarpaulins 4 on each support member 1 are pulled outwards at the same length, so that each support member 1 of the dustproof shed is distributed in a regular polygon in space. This increases the effective volume of the dust-free working space and also helps to maintain the uniform tension of the side wall tarpaulins 4 on each support member 1, thereby extending the service life of the dustproof shed.

[0055] Please see Figure 3 In some embodiments, each support member 1 further includes a first support arm 11 and a second support arm 12. Two first support arms 11 may be provided, extending radially outward from the upper and lower ends of the axial direction of the first side of the support member 1, respectively. The two first support arms 11 are provided with corresponding first guide grooves 111. The first guide grooves 111 are configured to guide the sidewall tarpaulin 4 to be pulled outward or rolled up towards the first side of the support member 1. The connecting part 5 is configured to stop at the proximal end of the first guide groove 111 near the first side.

[0056] Two second support arms 12 can be provided, extending radially outward from the upper and lower ends of the axial direction of the second side of the support member 1, respectively. The two second support arms 12 are provided with corresponding second guide grooves 121. The second guide grooves 121 are connected to the connecting grooves 14. The second guide grooves 121 are configured to guide the connecting part 5 on the side wall tarpaulin 4 pulled out by the adjacent support member 1 to move closer to the second side of the support member 1 and guide the connecting part 5 to connect to the connecting grooves 14.

[0057] The first support arm 11 and the second support arm 12 provided on the support member 1 guide the side wall tarpaulin 4 to be pulled outward or rolled inward through the first guide groove 111, and guide the connecting part 5 on the side wall tarpaulin 4 pulled out by the adjacent support member 1 to move closer to the second side of the support member 1 through the second guide groove 121, and guide the connecting part 5 to connect to the connecting groove 14. This can prevent the side wall tarpaulin 4 from shifting in the pulling direction, and ensure that the upper and lower sides of the side wall tarpaulin 4 can be tightly fitted with the top tarpaulin 2 and the bearing plane respectively, thus ensuring the dust-free operation space. It also facilitates the quick and accurate connection between the side wall tarpaulin 4 pulled out by the adjacent support member 1 and the connecting groove 14 on the second side of the support member 1, further improving the disassembly and assembly efficiency of the dustproof shed.

[0058] In addition, the connecting part 5 is configured to stop at the proximal end of the first guide groove 111 near the first side, and can form a limiting effect on the far end of the side wall tarpaulin 4 through the connecting part 5 and the first support arm 11, preventing the side wall tarpaulin 4 from being completely rolled into the storage cavity 13 under the action of the winding mechanism 3, so that the side wall tarpaulin 4 can be pulled outward through the connecting part 5 when used next time.

[0059] Please see Figure 1In some embodiments, the top tarpaulin 2 is at least partially connected to the top surfaces of the first support arm 11 and the second support arm 12 located at the upper end. The support member 1 stands on the bearing plane, and the bottom surfaces of the first support arm 11 and the second support arm 12 located at the lower end at least partially abut against the bearing plane.

[0060] The first support arm 11 and the second support arm 12 provided on the support member 1 of this application can stably support the support member 1 on the bearing plane through the first support arm 11 and the second support arm 12 located at the lower end, which significantly increases the contact area between the support member 1 and the bearing plane, and improves the stability and reliability of the support member 1 standing on the bearing plane; it can also stably connect the top tarpaulin 2 to the top of the support member 1 through the first support arm 11 and the second support arm 12 located at the upper end, which significantly increases the fixed connection area between the top tarpaulin 2 and the top surface of the support member 1, and improves the stability and reliability of the top tarpaulin 2 fixed on the top surface of the support member 1, thereby significantly improving the overall structural stability and reliability of the dustproof shed after assembly, and reducing the risk of structural instability of the dustproof shed during use.

[0061] The length of the connecting part 5 in the axial direction of the support member 1 is preferably the same as the height of the far end of the side wall tarpaulin 4 in the axial direction of the support member 1. On the one hand, this allows the connecting part 5 to provide support for the far end of the side wall tarpaulin 4 in the entire height direction. With the guidance and direction limitation of the first guide groove 111 and the second guide groove 121, the twisting in the height direction of the side wall tarpaulin 4 after it is pulled out can be effectively avoided. On the other hand, it also allows the connecting part 5 to connect with the connecting groove 14 on the second side of the adjacent support member 1 with the maximum contact area, which improves the connection stability and reliability between the connecting part 5 and the connecting groove 14.

[0062] Please see Figure 2 In some embodiments, at least one sidewall tarpaulin 4 is provided with an inlet / outlet 41, which is configured to allow personnel to enter and exit the cleanroom work space. The inlet / outlet 41 can be directly opened on the sidewall tarpaulin 4, and preferably, at least one dust curtain 42 is detachably connected to the inlet / outlet 41. The dust curtain 42 is configured to cover the inlet / outlet 41. As an additional dustproof component of the dustproof shed, the dust curtain 42 can further prevent external dust and other contaminants from entering the cleanroom work space through the inlet / outlet 41, ensuring that the cleanliness inside the dustproof shed is not affected.

[0063] Preferably, the entrance / exit 41 is provided with two dust curtains 42, which are arranged side by side on the left and right along the length of the side wall tarpaulin 4, and the two dust curtains 42 overlap at least partially at their intersection, so that the two dust curtains 42 are closed more tightly, providing maximum dust protection and facilitating passage.

[0064] The dust curtain 42 is preferably connected to the inlet / outlet 41 by magnetic attraction to facilitate its installation and removal. Furthermore, the overlapping portion of the two dust curtains 42 can also be connected magnetically to ensure that the two dust curtains 42 fit tightly together when closed, forming an effective dust barrier.

[0065] Please see Figures 1 to 2 In some embodiments, the top tarpaulin 2 and the support member 1 can be detachably connected via Velcro (not shown). The Velcro includes a matte, adhesive portion 61 (e.g., ...). Figure 2 (as shown) and hook portion 62 (as shown) Figure 1 As shown in the diagram, the two are respectively disposed on the top tarpaulin 2 and the support member 1. For example, when the rough surface part 61 is disposed at the bottom corner of the top tarpaulin 2, the hook surface part 62 is disposed on the top surface of the support member 1; when the rough surface part 61 is disposed on the top surface of the support member 1, the hook surface part 62 is disposed at the bottom corner of the top tarpaulin 2.

[0066] Velcro has a simple structure, low cost, and good adhesion and durability. This application uses Velcro to achieve a detachable connection between the top tarpaulin 2 and the support member 1, which improves the ease of installation and removal of the top tarpaulin 2, reduces costs, and ensures that the top tarpaulin 2 is firmly connected to the support member 1, preventing the top tarpaulin 2 from falling off or loosening.

[0067] In some other embodiments, the top tarpaulin 2 and the support member 1 can also be detachably connected by magnetic attraction, snap-fit, adhesive bonding, threaded connection, etc. This application does not limit this, as long as a detachable connection between the top tarpaulin 2 and the support member 1 can be achieved.

[0068] In some embodiments, both the first guide groove 111 and the second guide groove 121 extend perpendicularly to the axial direction of the support member 1, and the angle between the first guide groove 111 and the second guide groove 121 on the horizontal plane is preferably equal to the ratio of 360° to the total number of support members 1. For example, when there are three support members 1, the three support members 1 are arranged in a triangle on the bearing plane, so that the angle between the first guide groove 111 and the second guide groove 121 on each support member 1 on the horizontal plane is equal to 120°. Figure 3As shown, when the total number of support members 1 is four, the four support members 1 are arranged in a quadrilateral shape on the bearing plane. Thus, the angle between the first guide groove 111 and the second guide groove 121 on each support member 1 on the horizontal plane is equal to 90°. By limiting the angle between the first guide groove 111 and the second guide groove 121 on the horizontal plane, this application ensures that the direction in which the side wall tarpaulin 4 is pulled outward matches the total number of support members 1, and ensures that the connecting part 5 at the far end of the side wall tarpaulin 4 can be stably connected to the connecting groove 14 on the second side of the adjacent support member 1 in the correct direction.

[0069] In some embodiments, the dustproof shed of this application further includes a magnetic suction component (not shown), which is disposed between the connecting groove 14 and the connecting portion 5 that is connected to the connecting groove 14. The magnetic suction component is configured to magnetically connect the connecting groove 14 and the connecting portion 5.

[0070] This application achieves a magnetic connection between the connecting groove 14 and the connecting part 5 through a magnetic suction component, which ensures the reliability of the connection between the connecting groove 14 and the connecting part 5, while significantly improving the ease of disassembly and assembly of the connecting groove 14 and the connecting part 5, and improving the efficiency of dustproof shed disassembly and assembly.

[0071] Please see Figure 3 In some embodiments, the magnetic attraction assembly includes at least one first magnetic element 71 and at least one second magnetic element 72 that magnetically attracts the first magnetic element 71. The first magnetic element 71 and the second magnetic element 72 are respectively disposed between the surfaces of the connecting groove 14 and the connecting portion 5. At least one of the first magnetic element 71 and the second magnetic element 72 is a magnet or an electromagnet. For example, when the first magnetic element 71 is a magnet or an electromagnet, the second magnetic element 72 can be a magnet or electromagnet with opposite magnetic poles to the first magnetic element 71; the second magnetic element 72 can also be a magnetic metal part that magnetically attracts the first magnetic element 71, and this application does not limit this.

[0072] Please see Figure 3 In some embodiments, the connecting groove 14 can be configured as a square groove structure extending along the axial direction of the support member 1, and the connecting portion 5 can be configured as a square column structure that at least partially matches the connecting groove 14. The magnetic attraction assembly includes a plurality of first magnetic elements 71 and a plurality of second magnetic elements 72 that magnetically attract each of the first magnetic elements 71. The plurality of first magnetic elements 71 can be disposed on the bottom wall of the connecting groove 14 facing the connecting portion 5, and the bottom wall of the connecting groove 14 is parallel to the second side of the support member 1. Preferably, the plurality of first magnetic elements 71 are evenly distributed at equal intervals along the axial direction of the support member 1.

[0073] Correspondingly, a plurality of second magnetic elements 72 are disposed on the outer end face of the connecting part 5 facing the bottom wall of the connecting groove 14. The positions of the plurality of second magnetic elements 72 on the outer end face of the connecting part 5 are directly opposite to the positions of the first magnetic elements 71, so as to ensure that when the connecting groove 14 and the connecting part 5 are connected by multiple sets of cooperating magnetic attraction of the first magnetic elements 71 and the second magnetic elements 72, the connecting part 5 is at least partially matched with the connecting groove 14, and the connecting part 5 and the connecting groove 14 will not be misaligned in the axial direction of the support member 1, ensuring that the connecting part 5 is connected to the connecting groove 14 in the correct position, and preventing the side wall tarpaulin 4 from shifting in the axial direction of the support member 1.

[0074] When assembling the dustproof shed, the user pulls out the side wall tarpaulin 4 on the first side of the support member 1 through the connecting part 5. Guided by the second guide groove 121 of the adjacent support member 1, the user slides the connecting part 5 at the far end of the side wall tarpaulin 4 to the connecting groove 14 close to the second side of the adjacent support member 1. When the connecting part 5 and the connecting groove 14 are close to the magnetic field range of the first magnetic component 71 and the second magnetic component 72, the connecting part 5 and the connecting groove 14 can be quickly connected by magnetic attraction. When disassembling the dustproof shed, the user can separate the connecting part 5 from the connecting groove 14 by applying an external force greater than the magnetic attraction force of the magnetic component to the connecting part 5, thereby realizing the quick disassembly of the dustproof shed, improving the efficiency of dustproof shed assembly and disassembly, saving assembly and disassembly time, and reducing labor input costs.

[0075] In some embodiments, the dustproof shed of this application further includes a limiting structure (not shown), which is disposed between the connecting groove 14 and the connecting part 5 that is connected to the connecting groove 14. The limiting structure is configured to lock and fix the connecting groove 14 and the connecting part 5 in the use state and to release the locking and fixing of the connecting groove 14 and the connecting part 5 in the non-use state.

[0076] This application uses a limiting structure to lock and fix the connecting groove 14 and the connecting part 5 in use, ensuring the stability and reliability of the connection between the connecting groove 14 and the connecting part 5 during use. This allows the various support components 1 and the side wall tarpaulin 4 of the dustproof shed to be firmly connected, enabling the dustproof shed as a whole to withstand greater tensile and shear forces. This further improves the overall structural stability of the dustproof shed and avoids structural instability caused by loose connections between components during use.

[0077] Please see Figure 5 In some embodiments, the limiting structure includes an elastic locking member 81 and an unlocking member 82. The elastic locking member 81 is movably connected to at least one side wall of the connecting groove 14. The elastic locking member 81 is configured to retract when pushed by the connecting part 5 to allow the connecting part 5 to be inserted into the connecting groove 14, and to extend after the connecting part 5 is inserted into the connecting groove 14 to prevent the connecting part 5 from disengaging from the connecting groove 14.

[0078] The unlocking member 82 is connected to the elastic locking member 81. The unlocking member 82 is configured to cause the elastic locking member 81 to retract when pulled by an external force, so as to release the restriction on the connecting part 5.

[0079] Please see Figure 5 In some embodiments, the support member 1 is provided with a receiving cavity 141 for accommodating the elastic locking member 81. The receiving cavity 141 is preferably arranged perpendicular to the axial direction of the support member 1, and it communicates with the connecting groove 14 and the external space. The elastic locking member 81 includes a locking tongue 811 movably connected to the receiving cavity 141 and a helical spring 812 elastically connected between the locking tongue 811 and the inner wall of the receiving cavity 141. One end of the locking tongue 811 extends movably into the connecting groove 14, and the other end extends movably out of the support member 1. The unlocking member 82 is fixedly connected to the other end of the locking tongue 811 extending out of the support member 1, so as to facilitate pulling by the user. When the unlocking member 82 is not subjected to force, the helical spring 812, under its own elastic force, drives one end of the locking tongue 811 to extend into the connecting groove 14. The locking tongue 811 has an inclined guide surface (not shown) at one end that abuts against the connecting part 5. During assembly, when the connecting part 5 is inserted into the connecting groove 14 along the pull-out direction of the side wall tarpaulin 4, the connecting part 5 at least partially abuts against the inclined guide surface. Under the action of the inclined guide surface, one end of the locking tongue 811 overcomes the elastic force of the coil spring 812 and retracts into the receiving cavity 141, thus allowing the connecting part 5 to be inserted into the connecting groove 14. After the connecting part 5 is inserted into the connecting groove 14, the connecting part 5 separates from the inclined guide surface of the locking tongue 811. At this time, the locking tongue 811 automatically extends under the elastic force of the coil spring 812 to form a stop on the connecting part 5, preventing the connecting part 5 from disengaging from the connecting groove 14 along the roll-up direction of the side wall tarpaulin 4, thus achieving locking of the connecting part 5 and the connecting groove 14 in the use state. Throughout the process, no external force is required to drive the elastic locking member 81 to move, enabling rapid connection between the connecting part 5 and the connecting groove 14.

[0080] When the dustproof shed needs to be disassembled after use, the user only needs to pull the unlocking piece 82 outward to overcome the elasticity of the coil spring 812, which will cause one end of the locking tongue 811 to retract into the receiving cavity 141, thereby releasing the restriction on the connecting part 5. Then, the user can easily pull the connecting part 5 out of the connecting groove 14 by applying an external force greater than the magnetic attraction force of the magnetic component, thus separating the connecting part 5 from the connecting groove 14. The operation is simple and convenient, improving the efficiency of dustproof shed assembly and disassembly.

[0081] Please see Figure 1 , Figure 3 and Figure 6 In some embodiments, the limiting structure includes a first fixing hole 142 (e.g., Figure 6 (as shown in the image), second fixing hole 51 (as shown in the image) Figure 3 As shown), threaded fastener 83 (as shown) Figure 1As shown in the diagram, the first fixing hole 142 penetrates at least one side wall of the connecting groove 14 along the first direction.

[0082] The second fixing hole 51 penetrates the connecting part 5 along a first direction, which is perpendicular to the direction in which the connecting part 5 is inserted into the connecting groove 14. After the connecting part 5 is inserted into the connecting groove 14, the second fixing hole 51 and the first fixing hole 142 are coaxially aligned.

[0083] The threaded fastener 83 locks and fixes the connecting part 5 to the connecting groove 14 through the first fixing hole 142 and the second fixing hole 51.

[0084] In use, the threaded fastener 83 limits the connecting part 5 in the connecting groove 14 through the first fixing hole 142 and the second fixing hole 51, ensuring the stability and reliability of the connection between the connecting groove 14 and the connecting part 5 during use. This allows the various supporting parts 1 and the side wall tarpaulin 4 of the dustproof shed to be firmly connected, enabling the dustproof shed as a whole to withstand greater tensile and shear forces. This further improves the overall structural stability of the dustproof shed and avoids structural instability caused by loose connections between components during use.

[0085] The threaded fastener 83 can be a screw or a bolt. When the threaded fastener 83 is a screw, the first fixing hole 142 and the second fixing hole 51 can be set as screw holes that mate with the screw. When the threaded fastener 83 is a bolt, the first fixing hole 142 and the second fixing hole 51 can be set as through holes that mate with the bolt, and the first fixing hole 142 penetrates through both sides of the connecting groove 14 so that the bolt thread penetrates through the connecting groove 14.

[0086] When the dustproof shed needs to be disassembled after use, the user only needs to remove the threaded fastener 83 to release the restriction on the connecting part 5. At this time, the user can easily pull the connecting part 5 out of the connecting groove 14 by applying an external force greater than the magnetic attraction force of the magnetic component to the connecting part 5, thereby realizing the separation of the connecting part 5 from the connecting groove 14. The operation is simple and convenient, which improves the efficiency of dustproof shed assembly and disassembly.

[0087] The limiting structure may include an elastic locking element 81, an unlocking element 82, a first fixing hole 142, a second fixing hole 51, and a threaded fastener 83. Alternatively, the limiting structure may include only the elastic locking element 81 and the unlocking element 82, or only the first fixing hole 142, the second fixing hole 51, and the threaded fastener 83. This application does not limit the choice of the limiting structure, and the appropriate option can be selected according to the actual needs of use.

[0088] Please see Figure 1 In some embodiments, each support member 1 further includes a fixing part 15 and a suction cup 16 (e.g., Figure 2As shown in the diagram, the anchor 17 and the fixing part 15 are axially fixedly connected to the third side of the support 1, with the third side facing away from the first and second sides. A suction cup 16 is disposed at the bottom of the fixing part 15 for adsorbing and fixing the support 1 onto the bearing plane. The anchor 17 is adjustablely connected to the fixing part 15 and is configured to move axially and / or circumferentially relative to the fixing part 15 to anchor the support 1 onto the bearing plane.

[0089] When a dustproof shed is arranged on a smooth or flat bearing surface, the support member 1 can be firmly adsorbed and fixed to the bearing surface by the suction cup 16 provided at the bottom of the fixing part 15. This improves the stability and reliability of the fixed connection between the support member 1 and the smooth or flat bearing surface, further improves the overall structural stability and reliability of the dustproof shed after assembly, and greatly reduces the risk of structural instability of the dustproof shed during use.

[0090] The anchor 17 can move axially and / or circumferentially relative to the fixing part 15. That is, the anchor 17 can reciprocate axially relative to the fixing part 15 to adjust the axial height of the anchor 17, and the anchor 17 can also reciprocate circumferentially relative to the fixing part 15 to adjust the circumferential position of the anchor 17. When arranging the dustproof canopy, if the bearing plane is not suitable for fixing the anchor 17, the anchor 17 can be moved axially upward to disengage from the bearing plane to prevent interference between the anchor 17 and the bearing plane.

[0091] When a dustproof shed is arranged on a bearing plane with a steel grating or other bearing plane that can be connected to the anchor 17, the anchor 17 can be adjusted to a suitable position axially and / or circumferentially relative to the fixing part 15 so as to fix the anchor 17 to the steel grating or other structures and thus fix the support 1.

[0092] The anchor 17 can be configured as a hook-like structure or as other suitable structures that can be detachably connected to the bearing plane or a structure such as a steel grating on the bearing plane. This application does not limit this.

[0093] The suction cup 16 and the anchor 17 can be used simultaneously to fix the support 1 on the bearing plane. Alternatively, the suction cup 16 and the anchor 17 can be used separately to fix the support 1 on the bearing plane. In actual use, the user can choose according to the actual site conditions. This application does not limit this choice.

[0094] Please see Figure 1In some embodiments, each support member 1 further includes a vacuum pump 18, which is fixedly connected to the fixing part 15 and forms an air passage communication with the suction cup 16. The vacuum pump 18 is used to extract air between the suction cup 16 and the bearing surface. By extracting air between the suction cup 16 and the bearing surface using the vacuum pump 18, compared with the non-powered suction cup 16, the air pressure between the suction cup 16 and the bearing surface can be further reduced, which significantly improves the stability and reliability of the fixed connection between the suction cup 16 and the bearing surface.

[0095] Please see Figure 1 In some embodiments, a movable part 19 that can be adjusted axially is movably connected to the fixed part 15. The movable part 19 is rotatably connected to the anchor 17 via a damping shaft to achieve position adjustment of the anchor 17 relative to the fixed part 15 in the axial and / or circumferential directions.
