[0001] The application belongs to the technical field of sunlight rooms, and particularly relates to an assembled sunlight room. BACKGROUND

[0002] With the improvement of people's requirements for the quality of life, sunlight rooms, as a building form capable of providing natural lighting and leisure space, are increasingly widely used. In order to improve construction efficiency, assembled sunlight rooms become the mainstream direction. There are various assembled sunlight room structures in the prior art. Patent No. CN221664361U, entitled "Assembled aluminum alloy solar sunlight room", discloses a sunlight room.

[0008] Preferably, the upper end of the opening and closing edge extends upward to form a limiting convex part, the limiting convex part is the same height or higher than the abutting part, the edge of the top plate is provided with a limiting edge groove matched with the limiting convex part, when the opening and closing edge is closed and locked, the limiting convex part moves into the limiting edge groove correspondingly to form transverse limiting of the top plate.

[0009] Preferably, the top end of the limiting convex part is provided with a rotatable locking piece through a rotating device, the locking piece is provided with an upper positioning hole, the side of the top plate close to the limiting edge groove is provided with an upper limiting hole, the top surface of the column is provided with an upper locking hole, the upper locking hole is provided with internal threads, when the locking piece is rotated to adhere to the upper surface of the top plate, the upper positioning hole, the upper limiting hole and the upper locking hole are positionally corresponding, and the upper locking part is sequentially inserted through the upper positioning hole and the upper limiting hole and is screwed into the upper locking hole, so as to lock the locking piece and press the top plate to be longitudinally limited in the installation cavity.

[0010] Preferably, the rotating device comprises a rotating end integrally formed at the top end of the limiting convex part and a connecting ear provided at the tail of the locking piece and matched with the rotating end, the rotating end is provided with a rotating groove penetrating through both ends thereof, the connecting ear is provided with a through hole corresponding to the rotating groove, and the locking rod is threadedly matched with the rotating groove, the locking piece can be locked or released by rotating the locking rod to realize limiting of the locking piece.

[0011] Preferably, the clamping groove is provided with a sealing structure covering the bottom wall and the side wall of the clamping groove.

[0012] Preferably, the opening and closing edge is rotationally connected with the column through a rotating shaft structure, the rotating shaft structure is a hinge or a hinge.

[0013] Preferably, the base is provided with four mounting holes matched with the columns, and the mounting holes are provided with locking devices for locking the columns.

[0014] By the technical scheme, the application has the following beneficial effects: four vertical columns are arranged on the four sides of the base, and a clamping groove for clamping the edge of the wallboard is arranged on the two vertical sides adjacent to the columns in the height direction, and one side of the clamping groove is designed as a rotatable opening and closing edge, which can be opened or closed by rotating the opening and closing edge. Specifically, when assembling the wallboard, first, the locking mechanism of the opening and closing edge is released, that is, the hand knob is twisted to make it disengage from the internal threaded hole on the connecting column, then the opening and closing edge is pulled outwards or directly turned outwards by the hand knob, so that the two opening and closing edges on the same side of the two columns are turned outwards relative to each other, and the connecting column in the clamping groove is exposed, then the wallboard is sleeved on the connecting column of the clamping groove through the limiting holes on both sides, at this time, the preliminary fixing of the wallboard is completed, then the opening and closing edge is turned back, so that the inner side of the opening and closing edge closely abuts against the outer surface of the wallboard, and the locking hole on the opening and closing edge is coaxially corresponding with the limiting hole on the wallboard and the internal threaded hole on the connecting column, finally, the threaded part of the hand knob is inserted into the locking hole and the limiting hole and screwed into the internal threaded hole, and the secondary fixing of the wallboard is completed.

[0015] In addition, the product is designed with an independent hand knob locking mechanism for each wallboard. When a specific wallboard needs to be repaired or replaced, only the corresponding hand knob and opening and closing edge on both sides of the board need to be operated, realizing modular independent disassembly. This greatly facilitates later maintenance, reduces maintenance cost, and ensures the stability of the overall structure during local repair, effectively solving the technical problem in the prior art that disassembling any board will affect the adjacent structure due to the internal linkage mechanism, thereby unable to independently disassemble and maintain a single wallboard.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0021] like Figures 1-9 As shown: A prefabricated sunroom includes a base 1, at least four vertical columns 2 arranged around the base 1, wall panels 3 connecting adjacent columns, and a roof 4 covering the top of all columns 2. The base 1 serves as the horizontal load-bearing surface of the entire structure, the four columns 2 form the vertical load-bearing frame and connecting hub of the sunroom, the four wall panels 3 fill the spaces between adjacent columns 2 to form the enclosure facade, at least one wall panel has a door for entering and exiting the sunroom, and the roof 4 serves as the roof of the sunroom. In addition, the wall panels 3 and the roof 4 are made of translucent materials such as tempered glass or polycarbonate panels. On the two adjacent vertical sides of the column 2, there are slots 201 along the height direction for engaging the edge of the wall panel 3. The cross-section of the slot 201 is U-shaped. One side wall of the slot 201 is designed as a movable opening and closing edge 202. The opening and closing edge 202 is rotatably connected to the main body of the column 2 through a pivot structure, which in this embodiment uses a heavy-duty hinge or an internal hinge. This allows it to rotate outward or inward around the vertical axis to open or close. The opening angle is usually greater than 90°, allowing it to be used as a door. When the opening and closing edge 202 is opened outward, the entrance of the slot 201 is fully open, providing a convenient installation channel for inserting the wall panel 3. When the opening and closing edge 202 is closed inward, it forms a complete cavity with the other fixed edge of the slot 201 to hold the edge of the wall panel 3.

[0022] like Figure 3 as well as Figures 6-9 As shown: At least one connecting post 203 is fixedly provided on one side of the slot 201 relative to the opening / closing edge 202. In this embodiment, two connecting posts 203 are provided, located at the upper and lower ends of the slot 201. The connecting posts 203 are spaced apart along the height direction of the slot 201. The connecting posts 203 are made of metal to increase the strength and stability of the fixation, and an internal threaded hole 204 is machined at the center of their end faces. Correspondingly, limiting holes 301 matching the diameter and position of the connecting posts 203 are provided on the vertical frame on both sides of the wall panel 3. On the opening / closing edge 202, a through locking hole 205 is provided at a position coaxial with each connecting post 203. Additionally, a handle is provided on the opening / closing edge 202 for easy pulling.

[0023] The installation of wall panel 3 is completed by manually turning the door handle 5. The manual door handle 5 consists of a handle and a threaded part. During installation, first, the opening edge 202 is opened outward, and then the wall panel 3 is vertically placed into the slot 201. During this process, the limiting hole 301 on the wall panel 3 will naturally fit into the connecting post 203, achieving initial lateral positioning and preventing the wall panel 3 from moving in the plane. Then, the opening edge 202 is closed inward. At this time, the locking hole 205, the frame of the wall panel 3, and the internal threaded hole 204 of the connecting post 203 automatically align concentrically. Finally, the threaded part of the manual door handle 5 is passed through the locking hole 205, and the handle is rotated by hand to screw its threads into the internal threaded hole 204 of the connecting post 203. As the handle 5 is tightened, the head of the handle exerts strong pressure on the opening and closing edge 202, thereby pressing the frame of the wall panel 3 tightly against the fixed side of the slot 201 through the opening and closing edge 202, forming an extremely secure clamping state. This process can be completed with one hand without any additional tools.

[0024] This installation method changes the traditional approach that relies on complex hidden mechanisms at the bottom or multi-point bolt fixing. It reduces the technical difficulty and physical exertion of installation, allowing even non-professionals to complete assembly efficiently and accurately. Furthermore, the locking of each wall panel unit is completely independent, facilitating subsequent independent maintenance and replacement.

[0025] like Figures 1-3 As shown in Figures 6-9: Each column 2 has an upwardly extending abutment portion 206 at its top. The abutment portion 206 is L-shaped and integrally formed with the column 2. After the four columns 2 are installed, their top abutment portions 206 together form a rectangular mounting cavity 207 that matches the size of the top plate 4, used to accommodate the top plate 4. The upper top surface of the column 2, i.e., the supporting plane inside the abutment portion 206, is used to directly support the corners of the top plate 4, providing the main vertical support.

[0026] like Figures 1-9 As shown: To achieve more reliable fixing of the top plate 4, a linkage locking structure is provided on the opening and closing edge 202. This linkage locking structure includes a limiting protrusion 208 extending upwards from the upper end of the opening and closing edge 202. The limiting protrusion 208 and the opening and closing edge 202 are integrally formed, and its height is flush with or slightly higher than the abutment part 206. A limiting groove 401 matching the cross-section of the limiting protrusion 208 is machined below the edge of the top plate 4. When the wall panel 3 is installed and the opening and closing edge 202 is closed, the limiting protrusion 208 slides horizontally into the limiting groove 401 at the edge of the top plate 4. This fit constitutes a lateral limiting of the top plate 4, effectively preventing any sliding in the horizontal plane. In this embodiment, there are two corresponding sets of limiting protrusions 208, totaling four limiting protrusions 208, and two limiting grooves 401 are respectively provided on both sides of the top plate 4. The combination of these two allows for stable installation of the wall panel 3.

[0027] like Figures 1-9 As shown: The top of the limiting protrusion 208 is provided with a rotatable locking plate 6 via a rotating device. The locking plate 6 has an upper positioning hole 601. The top plate 4 has an upper limit positioning hole 402 on the side near the limiting side groove 401. The top surface of the column 2 has an upper locking hole 209 with an internal thread. Rotating the locking plate 6 can control the locking plate 6 to switch between the upright storage state and the flat working state and lock it in position. When the locking plate 6 rotates to fit the upper surface of the top plate 4, the upper positioning hole 601, the upper limit positioning hole 402 and the upper locking hole 209 are in corresponding positions. It also includes an upper locking member 7. The upper locking member 7 passes through the upper positioning hole 601 and the upper limit positioning hole 402 in sequence and screws into the upper locking hole 209, thereby locking the locking plate 6 and pressing the top plate 4, so that its longitudinal position is limited within the mounting cavity 207. When installing the top plate 4, it is first hoisted into the mounting cavity 207 and supported by the four corners. Close all opening and closing edges 202 to complete the lateral limiting. Then, rotate the locking pieces 6 at each corner from the vertical position to the horizontal position, so that they are flat against the upper surface of the top plate 4. At this time, the upper positioning hole 601, the upper limit hole 402, and the upper locking hole 209 are coaxial. Finally, use the upper locking piece 7, such as a bolt, to pass through the three holes in sequence and screw it into the upper locking hole 209. Tighten the upper locking piece 7, and the locking piece 6 will press down on the top plate 4 to complete the longitudinal locking. The specific operation is as follows: By providing upwardly extending abutment portions 206 at the top of all columns 2, these abutment portions 206 together form an installation cavity 207 for placing the top plate 4, and the top surface of each column 2 is used to abut the four corners of the top plate 4 respectively, this design can ensure that the top plate 4 can be accurately installed above the columns 2 and maintain a stable state. At the same time, a limiting protrusion 208 is provided above the opening and closing edge 202. The limiting protrusion 208 is generally flush with the height of the top plate 4 installed in the installation cavity 207, and a rotatable locking piece 6 is provided on the limiting protrusion 208. In addition, the edge of the top plate 4 is provided with a limiting side groove 401 that cooperates with the limiting protrusion 208. The limiting side groove 401 and the slot 201 are correspondingly provided, and the top plate 4 can be double-limited in both the lateral and longitudinal directions when it is fixed. Specifically, when installing the top plate 4, first place the top plate 4 into the installation cavity 207 to ensure that the upper surface of the top plate 4 is flush with the top of the abutment part 206. At this time, the positioning of the abutment parts 206 at the four corners makes each limiting groove 401 of the top plate 4 correspond to each slot 201. Then, rotate the opening and closing edge 202 inward so that the opening and closing edge 202 is engaged in the corresponding limiting protrusion 208 in the slot 201 and engaged in the limiting groove 401 to complete the lateral limiting of the top plate 4. Then, rotate the locking piece 6 until it is attached to the upper surface of the top plate 4 so that the upper positioning hole 601 on it is coaxially corresponding with the upper limit hole 402 on the top plate 4 and the upper locking hole 209 on the top surface of the column 2. Then, lock it with a locking piece 7 to achieve the longitudinal limiting of the top plate 4. This method can ensure the stability of the connection of the top plate 4. With the above structure, when the top plate 4 needs to be disassembled separately, simply release the locking piece 7, flip the locking piece 6 to the vertical position, and then lift the top plate 4 from the top to take it out. This process will not affect the stability of the connection relationship of other wall panels 3.

[0028] like Figure 6 As shown: The rotating device includes a rotating end integrally formed on the top of the limiting protrusion 208, and a connecting ear provided at the tail of the locking piece 6 and cooperating with the rotating end. The rotating end is provided with a rotating groove passing through both ends of it, and the connecting ear is provided with a through hole corresponding to the rotating groove. It also includes a locking rod, which is threadedly engaged with the rotating groove. By rotating the locking rod, the locking piece 6 can be locked or released to limit the locking piece 6.

[0029] The slot 201 is equipped with a sealing structure. In this embodiment, the sealing structure is a rubber sealing strip. The sealing structure covers the bottom wall and side wall of the slot 201. When the wall panel 3 is pressed, the sealing strip is deformed by pressure, forming a continuous and reliable sealing line on the contact surface, which significantly improves the waterproof, airtight and heat insulation and sound insulation performance of the sunroom.

[0030] like Figure 4As shown: The base 1 is provided with four mounting holes 101 that match the column 2. After the lower end of the column 2 is inserted, it can be fastened by the locking device preset in the mounting hole 101. In this embodiment, the locking device is such as a lateral screw or a pre-embedded nut in combination with a bolt, to ensure the verticality of the column and the firmness of the root, and to provide a stable foundation for the upper structure.

[0031] The specific assembly method of this invention is as follows: First, insert the lower ends of the four uprights 2 into the four mounting holes 101 of the base 1, and fix them vertically using a locking device. Then, install the wall panels 3. For any two adjacent uprights 2, the operator first flips outward to open the opening edges 202 on both uprights 2, fully opening the slot 201 entrance. Next, lift one wall panel 3 vertically, aligning the limiting holes 301 on both sides with the connecting post 203 in the slot 201, and then insert it downward, allowing the connecting post 203 to pass through the limiting holes 301, completing the initial positioning of the wall panel 3. Afterward, flip inward to close the opening edges 202 on both sides. At this time, the locking holes 205 on the opening edges 202 will automatically align with the limiting holes 301 of the wall panel 3 and the internal threaded holes 204 of the connecting post 203. Finally, remove the hand-tightened door handle 5, pass its threaded part through the locking hole 205 and the limiting hole 301 in sequence, and screw it into the internal threaded hole 204 of the connecting column 203. Tighten it by hand to lock the opening and closing edge 202 and firmly press the wall panel 3 into the slot 201. Repeat this step to complete the installation of all four wall panels 3. Finally, install the top panel 4. Hoist or lift the top panel 4 and place it smoothly into the installation cavity 207 formed by the abutment part 206 at the top of the four columns 2, ensuring that its corners are supported. At this time, close all the opening and closing edges 202, and the limiting protrusions 208 on them will automatically embed into the limiting edge grooves 401 on the edge of the top panel 4 to achieve lateral limiting. Next, rotate the locking pieces 6 at each corner from a vertical position to a horizontal position, so that they are flat against the upper surface of the top plate 4, ensuring that the upper positioning hole 601 on the locking piece 6, the upper limit positioning hole 402 on the top plate 4, and the upper locking hole 209 on the top surface of the column 2 are coaxial. Finally, use the upper locking component 7, such as a bolt, to pass through the upper positioning hole 601 and the upper limit positioning hole 402 in sequence, and screw it into the upper locking hole 209 to tighten it, thereby pressing the top plate 4 downward through the locking pieces 6, completing the longitudinal fixation.

[0032] like Figure 3The independent disassembly method of the wall panel shown is as follows: The advantage of this design is that a single wall panel 3 can be repaired or replaced independently. Specifically, there are two situations: 1. Remove the wall panel with the locking plate 6 in the locked state. When it is necessary to replace or repair a wall panel 3, if the locking plate 6 of the top plate 4 above that position is in the locked state, the operator first needs to use a tool to loosen the corresponding upper locking pieces 7 on both sides of the wall panel 3, and flip the locking plate 6 upward to a vertical position to release it from the pressure on the top plate 4. Then, rotate it in the opposite direction by hand and remove the hand-tightened door handle 5. At this time, the locking of the opening and closing edge 202 is released. Pull it by hand or use a tool to flip it outward to open the opening and closing edges 202 on both sides, and the wall panel 3 can be lifted vertically upward to disengage its limiting hole 301 from the connecting column 203, thereby completely removing it. This process only affects the local locking of the target wall panel 3 and the top plate 4 directly above it, and does not affect the structural stability of other parts of the sunroom. 2. Remove the wall panel with the locking plate 6 in the open position. If the locking plate 6 on the top plate 4 above the target wall panel 3 is already in the open position, disassembly is even simpler. The operator can directly rotate the handle 5 in the opposite direction by hand to remove it, release the locking of the opening and closing edges 202, and then flip the two opening and closing edges 202 outward to open them, allowing the wall panel 3 to be lifted vertically upward. This method fully realizes the independent modular disassembly and assembly of the wall panel 3.

[0033] like Figure 2 The disassembly method for the top plate is as follows: When it is necessary to disassemble the top plate 4, firstly, operate the four corners in sequence, using tools to loosen and remove all four upper locking pieces 7. Then, flip all four locking pieces 6 upwards to a vertical position, so that they are completely detached from the upper surface of the top plate 4. At this time, the longitudinal clamping force of the top plate 4 is completely released. Subsequently, the operator can slightly flip any one or both opening edges 202 outwards one by one. When the opening edge 202 moves outwards, the limiting protrusion 208 on it will disengage from the limiting edge groove 401 of the top plate 4, thereby releasing the lateral limiting of the top plate 4. Finally, the operator can smoothly lift the top plate 4 upwards and remove it from the mounting cavity 207. The entire disassembly process does not require touching the fixing mechanism of the wall panel 3, ensuring the integrity of the wall structure.
