[0026] The embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] According to an embodiment of the present invention, a support device for adding floors to a house includes a support structure (reference numeral 1) and a connecting structure (reference numeral 2). The support structure (reference numeral 1) includes a fixed support plate 100, a movable support plate 110, and a telescopic support plate 120. The fixed support plate 100, the movable support plate 110, and the telescopic support plate 120 form a triangular structure. The fixed support plate 100 and the movable support plate 110 are pivotally connected by a fixing member 140 to change the included angle between them. The two ends of the telescopic support plate 120 are pivotally connected to the fixed support plate 100 and the movable support plate 110 by mounting seats 150. A locking mechanism 160 is provided on the fixing member 140 for... The included angle between the fixed movable support plate 110 and the fixed support plate 100 is fixed. Positioning holes 170 are respectively provided on the movable support plate 110 and the fixed support plate 100 for the support bolts 160 to pass through. The support bolts 160 connect the movable support plate 110 and the fixed support plate 100 to the house. The connecting structure 2 is arranged between the two support structures (reference numeral: 1) and is detachably connected to the support structures (reference numeral: 1). The connecting structure 2 includes a connecting plate 200 and a connecting frame 210. The connecting frame 210 is arranged on the side of the fixed support plate 100 of the support structure (reference numeral: 1). The two ends of the connecting plate 200 are respectively inserted into the connecting frame 210 on the side of the fixed support plate 100 to fix the support structure (reference numeral: 1). There can be multiple positioning holes 170 on the fixed support plate 100 and the movable support plate 110. The support bolts 160 correspond one-to-one with the positioning holes 170. When the support bolts 160 enter the positioning holes 170, the fixed support plate 100 and the movable support plate 110 can be fixed to the wall of the house. Rotating the movable support plate 110 can change the included angle between the fixed support plate 100 and the movable support plate 110, and adjust the shape of the triangular structure to adapt to the wall of the house. The locking mechanism 160 is used to restrict the rotation of the movable support plate 110 and maintain the stability of the triangular structure. The length of the telescopic support plate 120 can be adjusted. As the movable support plate 110 rotates, the length of the telescopic support plate 120 changes to meet the changes of the triangular structure. The connecting structure 2 is used to connect the two support structures (see attached figure 1) to form a whole, which can improve the overall support effect and stability.

[0028] In some embodiments, the movable support plate 110 includes a first support plate 111 and a second support plate 112. A transmission mechanism 130 is provided on the first support plate 111. The second support plate 112 is slidably connected to the first support plate 111. The second support plate 112 is connected to the transmission mechanism 130 and moves relative to the first support plate 111 under the drive of the transmission mechanism 130.

[0029] Specifically, the movable support plate 110 is formed by the combination of the first support plate 111 and the second support plate 112. The overall length of the movable support plate 110 is adjusted by changing the distance between the two. The transmission mechanism 130 is used to drive the second support plate 112 to move. The transmission mechanism 130 can be a linear drive mechanism such as a cylinder or an electric push rod. The transmission mechanism 130 is fixed on the first support plate 111 to push the second support plate 112 to move relative to the first support plate 111.

[0030] In some embodiments, the transmission mechanism 130 includes a threaded rod 131, a knob 132, and a threaded plate 133. The threaded rod 131 is arranged in the first support plate 111. The first end of the threaded rod 131 is provided with a knob 132. The first support plate 111 has a hole corresponding to the knob 132 for turning the knob 132 to drive the threaded rod 131 to rotate. The second end of the threaded rod 131 is pivotally connected to the first support plate 111. The threaded plate 133 is threadedly connected to the threaded rod 131. One end of the threaded plate 133 passes through the guide groove 1110 on the side of the first support plate 111 and is connected to the second support plate 112. As the threaded rod 131 rotates, the threaded plate 133 slides along the guide groove 1110 and drives the second support plate 112 to move relative to the first support plate 111.

[0031] Specifically, the transmission mechanism 130, through the threaded engagement of the threaded rod 131 and the threaded plate 133, can drive the threaded plate 133 to move more precisely and stably, achieving precise control over the overall length of the moving support plate 110. The knob 132 is fixedly connected to the threaded rod 131. During use, the threaded rod 131 can be rotated using a belt, transmission chain, or manually. As the threaded rod 131 rotates, the threaded plate 133 moves relative to it. A cavity is provided within the first support plate 111 to accommodate the helical rod. A hole is provided on the surface corresponding to the knob 132 for easy rotation of the knob 132. A threaded plate 133 is arranged in the cavity. A portion of the threaded plate 133 extends out of the first support plate 111 through a guide groove 1110 and connects to the second support plate 112. The guide groove 1110 extends along the length direction of the first support plate 111. The threaded plate 133 slides along the guide groove 1110. The second support plate 112 is fixedly connected to the threaded plate 133 and moves along the length direction of the first support plate 111 as the threaded plate 133 moves, changing the overall length of the movable support plate 110.

[0032] In some embodiments, the transmission mechanism 130 further includes guide rods 134, a plurality of guide rods 134 being arranged alongside the threaded rod 131 along the extending direction of the first support plate 111, the guide rods 134 passing through the threaded plate 133 and being slidably connected to the threaded plate 133.

[0033] Specifically, guide rods 134 are arranged within the cavity of the first support plate 111. The guide rods 134 are parallel to the axial direction of the threaded rod 131. The guide rods 134 pass through the threaded plate 133, guiding it and preventing it from tilting or jamming within the cavity. Multiple guide rods 134 better constrain the movement path of the threaded plate 133, resulting in smoother movement of the second support plate 112. Furthermore, the multiple guide rods 134, in conjunction with the threaded rod 131, support the cavity inside the first support plate 111, thus ensuring the structural strength of the first support plate 111 to a certain extent.

[0034] In some embodiments, the second support plate 112 has a sliding groove 1120, the width of the groove 1120 being adapted to the width of the second end of the first support plate 111, and at least a portion of the first support plate 111 entering the sliding groove 1120.

[0035] Specifically, the sliding groove 1120 of the second support plate 112 is used to cooperate with the first support plate 111. The second end of the first support plate 111 enters the sliding groove 1120 and is slidably connected to the second support plate 112. The opening of the guide groove 1110 is directly opposite the groove wall of the sliding groove 1120. The threaded plate 133 extends out of the guide groove 1110 and is connected to the groove wall of the sliding groove 1120. The threaded plate 133 drives the second support plate 112 to move. Optionally, the two guide grooves 1110 are arranged on both sides of the first support plate 111. The two ends of the threaded plate 133 extend out of the guide groove 1110 and are respectively connected to the two side groove walls of the sliding groove 1120, which improves the stability of the connection between the first support plate 111 and the second support plate 112.

[0036] In some embodiments, the telescopic support plate 120 includes an outer support plate 121 and an inner support plate 122. At least a portion of the inner support plate 122 is slidably located inside the outer support plate 121. A limiting slide 123 is provided on the side of the outer support plate 121. A limiting slider 124 is slidably provided on the limiting slide 123. The limiting slider 124 is connected to the inner support plate 122.

[0037] Specifically, the outer support plate 121 of the telescopic support plate 120 has a guide hole, a portion of the inner support plate 122 enters the guide hole and slides relative to the outer support plate 121, the limiting slide 123 is connected to the guide hole, the limiting slider 124 is fixedly connected to the inner support plate 122, the limiting slide 123 extends along the length direction of the outer support plate 121, the limiting slider 124 slides along the limiting slide 123, which can drive the inner support plate 122 to move relative to the outer support plate 121, the limiting slide 123 constrains the limiting slider 124, which can prevent the inner support plate 122 from coming off the outer support plate 121, the limiting slide 123 guides the limiting slider 124 to move, so that the inner support plate 122 moves smoothly, the telescopic support plate 120 adapts to the angle and length changes between the moving support plate 110 and the fixed support plate 100 through the cooperation of the inner support plate 122 and the outer support plate 121, and maintains the stability of the triangular structure.

[0038] In some embodiments, the fixing member 140 includes a rotating shaft 141 and at least two fixing blocks 142. The fixing blocks 142 are arranged at the first end of the fixed support plate 100 and are symmetrically arranged about the fixed support plate 100. The first end of the first support plate 111 is provided with a hole for the rotating shaft 141 to pass through. The rotating shaft 141 passes through the fixing blocks 142 and the first support plate 111.

[0039] Specifically, the two fixing blocks 142 of the fixing member 140 are arranged on both sides of the fixed support plate 100, the rotating shaft 141 passes through the first support plate 111, and the two ends of the rotating shaft 141 respectively enter the fixing blocks 142 on both sides of the fixed support plate 100. The fixed support plate 100 is fixed to the wall of the house. The rotating shaft 141 is used to cooperate with the first support plate 111 of the movable support plate 110 to rotate. The fixing member 140 is arranged on both sides of the first support plate 111 to protect the first support plate 111 and the second support plate 112.

[0040] In some embodiments, an arc-shaped slide 143 is provided on the fixing block 142, and the locking mechanism 160 includes a locking rod and a locking nut 162. The locking rod 161 enters the first support plate 111 through the arc-shaped slide 143. At least a portion of the locking rod 161 is located outside the fixing block 142 and is threadedly connected to the locking nut 162. The locking nut 162 abuts against the fixing block 142 to lock the first support plate 111 and the locking rod 161.

[0041] Specifically, the locking rod can move within the arc-shaped slide 143. The locking rod passes through the first support plate 111. As the first support plate 111 rotates relative to the fixed support plate 100, the locking rod moves within the arc-shaped slide 143. The two ends of the locking rod 161 are located outside the fixed block 142. It can be understood that the length of the locking rod 161 is greater than the width of the first support plate 111. The two ends of the locking rod 161 are threaded. The locking nut 162 is threadedly connected to the locking rod 161. The locking nut 162 is rotated until it abuts against the fixed block 142 and then stops. The static friction between the locking nut 162 and the fixed block 142 prevents the locking rod 161 from moving relative to the arc-shaped slide 143.

[0042] In some embodiments, the connecting structure 2 further includes an operation plate 220 and a connecting locking rod 230. The connecting locking rod 230 is located inside the connecting frame 210 and at least part of the connecting locking rod 230 passes through the connecting frame 210 and is connected to the operation plate 220. Inner plates 240 are provided at both ends of the connecting plate 200. Locking holes 241 are provided on the inner plates 240. Part of the connecting locking rod 230 enters the locking holes 241 to lock the inner plates 240.

[0043] Specifically, the connecting locking rod 230 is arranged inside the connecting frame 210. One end of the connecting frame 210 extends out of the connecting frame 210 and is connected to the operating plate 220 outside the connecting frame 210. Pulling the operating plate 220 can change the position of the connecting locking rod 230 relative to the connecting frame 210. The inner plate 240 is arranged at both ends of the connecting plate 200, and the length and width of the inner plate 240 are smaller than those of the connecting plate 200. The shape of the inner plate 240 matches the connecting frame 210. After the inner plate 240 enters the connecting frame 210, the connecting locking rod 230 enters the lock hole 241 to lock the inner plate 240. Thus, the connecting frame 210 and the connecting plate 200 are fixed, and the two support structures (see attached drawing 1) can be formed into a whole through the connecting plate 200.

[0044] In some embodiments, a spring is provided between the operation plate 220 and the connecting frame 210, the spring is sleeved on the connecting locking rod 230 and the two ends of the spring are respectively connected to the operation plate 220 and the connecting frame 210.

[0045] Specifically, the spring is fitted onto the connecting locking rod 230. When in use, pulling the operating plate 220 causes the connecting locking rod 230 to move outward from the connecting frame 210. The spring stretches and undergoes elastic deformation. After the inner plate 240 enters the connecting frame 210, the operating plate 220 is released. The spring returns to its original deformation and causes the operating plate 220 to reset. The connecting locking rod 230 enters the locking hole 241 of the inner plate 240 and completes the locking. This enables the automatic reset and locking of the connecting locking rod 230.
