[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 4 As shown, the technical solution adopted by the utility model is as follows: an assembled house support frame, including a plurality of vertically arranged columns 1 and locking pieces, preferably four columns 1 in this embodiment, a connecting plate 4 is horizontally clamped between two adjacent columns 1, and both ends of the connecting plate 4 are connected to the columns 1 through locking pieces. When the four columns 1 are respectively fixedly connected to the ground, and a connecting plate 4 is connected between two adjacent columns 1 through locking pieces, the whole is spliced ​​into a rectangular frame.

[0023] Two support plates are fixedly arranged on the side walls around each column 1 along the height direction thereof. The two support plates are symmetrically provided with a plurality of insertion holes 2 along the height direction thereof. The plurality of insertion holes 2 are arranged in a straight line from top to bottom.

[0024] A plurality of circular holes 3 are provided on the side walls of each column 1 along the height direction thereof, and the circular holes 3 are arranged in a straight line from top to bottom. In addition, the circular holes 3 are located between two supporting plates on the same side of the same column 1. The circular holes 3 between the facing surfaces of two adjacent columns 1 correspond to each other one by one and the openings thereof are opposite to each other.

[0025] Both ends of each connecting plate 4 are provided with connecting holes 5, which correspond to the openings of the sockets 2 on the two uprights 1 adapted to the two ends of the connecting plate 4. Moreover, the connecting holes 5 and the sockets 2 have the same size.

[0026] Insertion rods 6 are fixedly arranged at both ends of each connecting plate 4. The insertion rods 6 are made of an elastic material, specifically stainless steel or copper. The insertion rods 6 at both ends of the connecting plate 4 are plugged into and matched with the round holes 3 on the two columns 1 adapted to the two ends of the connecting plate 4. The initial positioning of the connecting plate 4 is completed by inserting the insertion rods 6 at both ends of the connecting plate 4 into the corresponding round holes 3.

[0027] The locking member includes a plug plate 10, a truncated cone-shaped hole is coaxially provided in the insertion rod 6, and a truncated cone top column 8 is slidably arranged in the truncated cone-shaped hole. The end surface radius of the truncated cone top column 8 close to the connecting plate 4 is larger than the end surface radius of the truncated cone top column 8 away from the connecting plate 4, and the truncated cone-shaped hole matches the truncated cone top column 8. A truncated cone-shaped sliding groove is provided on the connecting plate 4, and the truncated cone-shaped sliding groove is connected with the connecting hole 5. One end of the truncated cone top column 8 close to the connecting plate 4 passes through the truncated cone-shaped sliding groove and extends into the connecting hole 5. In addition, the smallest notch of the truncated cone-shaped sliding groove is larger than the largest longitudinal section of the truncated cone top column 8, so as to facilitate the sliding of the truncated cone top column 8 in the insertion rod 6.

[0028] A plurality of limit grooves 7 are symmetrically provided in the center of the insertion rod 6. The limit grooves 7 are evenly distributed along the circumference of the insertion rod 6 and are all connected to the truncated cone hole. Each limit groove 7 is sealed in the direction close to the connecting plate 4, and each limit groove 7 is open in the direction away from the connecting plate 4. A plurality of limit blocks 9 are fixedly provided on the end of the outer surface of the truncated cone top column 8 away from the connecting plate 4. The limit blocks 9 correspond to the limit grooves 7 one by one and are slidably matched. When the truncated cone top column 8 slides in the truncated cone hole in the direction away from the connecting plate 4, the limit blocks 9 slide in the same direction in the limit grooves 7, so as to expand the end of the insertion rod 6 away from the connecting plate 4, so as to facilitate the close fit between the insertion rod 6 and the inner wall of the circular hole 3, thereby improving the limiting effect on the connecting plate 4.

[0029] At the same time, the blocking setting at one end of the limiting groove 7 can prevent the truncated cone top column 8 from falling into the connecting hole 5 during transportation. The opening setting at one end of the limiting groove 7 is more conducive to the expansion and support of the insertion rod 6.

[0030] The plug plate 10 is slidably arranged in the insertion hole 2 and the connection hole 5. The matching surfaces of the plug plate 10 and the truncated cone top column 8 are both arc surfaces, and the plug plate 10 is interference-fitted with the insertion hole 2 and the connection hole 5. Working principle: When assembling, first fix a column 1 on the ground.

[0031] Then, the insertion rod 6 at one end of one of the connecting plates 4 is inserted into the appropriate circular hole 3 of the column 1 to keep the horizontal state of the connecting plate 4. The insertion rod 6 at the other end of the connecting plate 4 is inserted into the same position of the other column 1, thereby completing the connection between the two columns 1.

[0032] Repeat the above steps to splice the four columns 1 into a rectangular frame.

[0033] When the plug rod 6 is inserted into the round hole 3, the plug hole 2 is aligned with the connecting hole 5. The plug plate 10 is inserted into the plug hole 2 and the connecting hole 5. Since the plug plate 10 is interference fit with the plug hole 2 and the connecting hole 5, an impact tool is required when installing and inserting the plug plate 10.

[0034] After the plug plate 10 is inserted into the connection hole 5, it will contact the truncated cone top column 8 and push the truncated cone top column 8 to slide in the direction away from the connection plate 4. Since the truncated cone hole and the truncated cone top column 8 are matched, the truncated cone top column 8 will gradually expand the insertion rod 6 during the sliding process, so that the insertion rod 6 expands outward and fits tightly with the inner wall of the circular hole 3 until the plug plate 10 is fully inserted and the installation is completed.

[0035] At the same time, during the sliding of the truncated cone top column 8, the limiting block 9 will slide in the limiting groove 7 so as to achieve a better expansion effect of the insertion rod 6.
