Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic shielding, in particular to a simple assembled electromagnetic shielding room. Background Art

[0002] Against the background of rapid development of the medical device industry, a large number of manufacturers of electromagnetic shielding rooms have emerged across the country. Most of them use the original technology of traditional galvanized steel plate shielding or copper plate welding shielding. The electromagnetic shielding room is an important part of the field of electromagnetic compatibility (EMC). The electromagnetic shielding room is a steel house. Cold-rolled steel plate is its main shielding material, including six-sided shells, doors, windows and other general house elements. It only requires strict electromagnetic sealing performance and corresponding shielding treatment for all inlet and outlet pipelines, thereby blocking the entry and exit of electromagnetic radiation.

[0003] For example, CN210202347U discloses a simple assembled electromagnetic shielding room with a pre-set structure, and the key points of its technical solution are: a shielding room body, the shielding room body includes a floor module, a side panel module, a ceiling module, a column keel and a horizontal keel, the upper and lower ends of each column keel are respectively connected to two horizontal keels through two reinforcement members, the reinforcement member includes a connecting plate, and end seat plates extend from both ends of the connecting plate, the upper end seat plate is fixedly connected to the side wall of the column keel by screws, and the lower end seat plate is fixedly connected to the top wall of the horizontal keel by screws; it can be pre-designed mainly through the arrangement of the overall keel frame, and only simple construction work needs to be carried out on site. The floor module, side panel module and ceiling module used in the electromagnetic shielding room can be predetermined and manufactured according to needs, the adjacent two side panel splices are clamped by the first vertical keel and the second vertical keel, and the adjacent two top panel splices are clamped by the first longitudinal keel and the second longitudinal keel, so that the structure is simple and stable, and the effect is good.

[0004] However, it still has some disadvantages in actual use. For example, the current electromagnetic shielding room is mainly fixed by welding with fixed welds or by screws and mortise and tenon joints between the keels. The use of screws and mortise and tenon joints will increase the difficulty of installing the overall structure and make it difficult to reproduce the structure. At the same time, the mortise and tenon and screw structures will become loose and the screws will be twisted after repeated disassembly and assembly. The welding method makes it impossible to flexibly disassemble and reinstall the entire structure during subsequent disassembly and assembly. Since the welding method is mostly a single fixing effect, destructive disassembly can only be performed during replacement, which is difficult and inefficient. In addition, since the matrix has been deformed after destruction and cannot be reused, the economic value of the overall structure is low and the utilization rate is limited.

[0005] In view of the existing structure and deficiencies, research and improvements are conducted to provide a simple assembled electromagnetic shielding room in order to achieve a more practical purpose. Summary of the invention

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies in the prior art, the utility model provides a simple assembled electromagnetic shielding room, which solves the problem that the electromagnetic shielding room as a whole is mainly fixed by welding with fixed welds, and the whole cannot be flexibly disassembled and reinstalled during subsequent disassembly, assembly and updating. Since the welding method is mostly a single fixing effect, destructive disassembly can only be performed for replacement, which is difficult and inefficient, and the matrix cannot be reused because it has been deformed after destruction.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a simple assembled electromagnetic shielding room, comprising a first fixed side panel, a second fixed side panel is detachably installed on the side of the first fixed side panel, a protective top panel is placed on the top of the first fixed side panel and the second fixed side panel, an arc-shaped side panel is fixedly installed on one side of the second fixed side panel, an arc-shaped slot is opened inside the arc-shaped side panel, an arc-shaped curved surface is seamlessly connected and fixed at one side opening of the arc-shaped slot, a fixed top panel is symmetrically installed on the upper and lower ends of the surface of the first fixed side panel, a fixed turntable is opened inside the fixed top panel, a connecting side panel is rotatably mounted inside the fixed turntable, a fixed shaft matched with the fixed turntable is embedded in one end of the connecting side panel, a clearance fit is adopted between the fixed shaft and the fixed turntable, a tension spring is embedded in the other end of the connecting side panel, and a fixed panel is embedded in the other end of the tension spring.

[0009] Preferably, the other end of the fixed panel is inlaid with a connecting square plate, the side surface of the connecting square plate is inlaid with a semicircle, and the side surface of the connecting square plate is inlaid with a fixed baffle.

[0010] Preferably, a limit head is inlaid and installed at the other end of the fixed baffle, and the overall shape of the limit head is cylindrical, and the side surfaces of the connecting side plate and the fixed insert are inlaid with contacts.

[0011] Preferably, an elastic rope is installed between the contact points on the connecting side plate and the fixed panel, and the elastic rope is made of elastic material.

[0012] Preferably, the surfaces of the semicircle and the limiting head are both smooth, and one end of the limiting head cooperates with one end of the arc-shaped notch.

[0013] Preferably, the tension spring is located at the center of the connecting side plate and the fixed panel, and the surface of the tension spring is evenly coated with a layer of lubricating grease, and the center position of the arc-shaped notch is kept horizontal with the midpoint position of the limit head.

[0014] Preferably, the surface of the arc-shaped curved surface is evenly coated with a layer of lubricating grease, and one end of the arc-shaped curved surface is higher than the horizontal position of the arc-shaped groove, the top end of the arc-shaped side panel is an arc-shaped structure, and there is a gap between the semicircle and the limit head, and the gap range is compatible with the top thickness value range of the arc-shaped side panel.

[0015] The utility model provides a simple assembled electromagnetic shielding room, which has the following beneficial effects:

[0016] (1) The utility model provides an arc-shaped side plate and an arc-shaped notch as well as a fixed panel and a stretching spring, and utilizes the mutual cooperation of the plurality of them. The operator gradually drives the stretching spring to perform a stretching operation by the fixed panel. During the stretching process, the connecting side plate at the other end of the stretching spring will be adapted and rotated inside the fixed rotating port through the fixed rotating shaft at its tail end to ensure the flexible rotation of the fixed panel during the stretching, until the limit head at one end of the fixed panel slides and fits onto the arc-shaped surface. At this time, the limit head is inside the arc-shaped notch, thereby releasing the fixed panel. At this time, the fixed panel gradually slides along the surface of the arc-shaped surface and is embedded into the fixed panel under the reverse force of the stretching spring at its tail end. The depth of the arc-shaped notch completes the fixing effect between the fixed panel and the arc-shaped side panel, thereby connecting and fixing the first fixed side panel and the second fixed side panel at both ends thereof. When disassembling and assembling later, it is only necessary to hold the fixed panel in the opposite direction and stretch and slide it toward the outer opening of the arc-shaped notch to separate the fixed panel and the arc-shaped side panel, thereby completing the disassembly work between the first fixed side panel and the second fixed side panel. This process will not affect the overall structural strength of the first fixed side panel and the second fixed side panel, and the purpose of non-destructive disassembly and assembly can be achieved. Later, the location can be changed for reciprocating disassembly and installation, thereby improving the practicality and economic benefits of the overall structure.

[0017] (2) The utility model provides a tension spring and a fixed panel, and connects the side panels and an elastic rope. The elastic rope is made of an elastic material. When the connecting side panels and the fixed panel pull the tension spring against each other, the stability of the left and right ends of the connecting side panels and the fixed panel can be effectively ensured, thereby assisting the tension spring in the middle to maintain a horizontal tension effect, making it less likely to deviate and twist.

[0026] The other end of the fixed panel 12 is inlaid with a connecting square plate 13, the side of the connecting square plate 13 is inlaid with a semicircle 14, the side of the connecting square plate 13 is inlaid with a fixed baffle 15, the other end of the fixed baffle 15 is inlaid with a limit head 16, the overall shape of the limit head 16 is cylindrical, the sides of the connecting side plate 10 and the fixed panel 12 are inlaid with contacts 17, the surfaces of the semicircle 14 and the limit head 16 are smooth, and one end of the limit head 16 cooperates with one end of the arc-shaped notch 5, the tension spring 11 is located at the center of the connecting side plate 10 and the fixed panel 12, and the surface of the tension spring 11 is evenly coated with a layer of lubricating grease, and the center position of the arc-shaped notch 5 is kept horizontal with the midpoint position of the limit head 16.

[0027] For details, please refer to the attached manual Figure 2-4 An elastic rope 18 is installed between the connecting side plate 10 and the contact 17 on the fixed panel 12. The elastic rope 18 is made of elastic material. The surface of the arc surface 6 is evenly coated with a layer of lubricating grease, and one end of the arc surface 6 is higher than the horizontal position of the arc groove 5. The top of the arc side plate 4 is an arc-shaped structure. There is a gap between the semicircle 14 and the limit head 16, and the gap range is compatible with the top thickness value range of the arc side plate 4.

[0028] The specific implementation method is: the elastic rope 18 is made of elastic material as a whole, so that when the side panel 10 and the fixed panel 12 are connected to pull the tension spring 11 against each other, the stability of the left and right ends of the side panel 10 and the fixed panel 12 can be effectively guaranteed, thereby assisting the middle tension spring 11 to maintain a horizontal tension effect, making it less likely to have the problem of displacement and distortion.

[0029] The working principle of this utility model:

[0030] Step 1: First, the operator assembles the various components of the device normally, and then starts the device normally.

[0031] Step 2: First, the operator gradually drives the tension spring 11 with the fixed panel 12 to perform the tensioning operation. During the tensioning process, the connecting side plate 10 at the other end of the tension spring 11 will be adapted and rotated inside the fixed rotating port 8 through the fixed rotating shaft 9 at its tail end to ensure the flexible rotation of the fixed panel 12 during the tensioning, until the limit head 16 at one end of the fixed panel 12 slides and fits onto the arc surface 6. At this time, the limit head 16 is inside the arc notch 5, thereby releasing the fixed panel 12. At this time, the fixed panel 12 gradually slides along the surface of the arc surface 6 and is embedded into the depth of the arc notch 5 under the reverse force of the tension spring 11 at its tail end, thereby completing the tensioning operation. The fixing effect between the fixed panel 12 and the arc-shaped side panel 4 is achieved, so that the first fixed side panel 1 and the second fixed side panel 2 at both ends are connected and fixed. When disassembling and assembling laterally, it is only necessary to hold the fixed panel 12 in the opposite direction and stretch it to slide outward from the outer opening of the arc-shaped notch 5, so as to separate the fixed panel 12 and the arc-shaped side panel 4, and then complete the disassembly work between the first fixed side panel 1 and the second fixed side panel 2. This process will not affect the overall structural strength of the first fixed side panel 1 and the second fixed side panel 2, and can achieve the purpose of non-destructive disassembly and assembly. Later, the location can be changed for reciprocating disassembly and installation, thereby improving the practicality and economic benefits of its overall structure.

[0032] Step 3: First, the operator shuts down the device normally, then checks whether the fixation between the various components of the device is normal, and then replaces and repairs the aging and severely worn parts inside the device.
