[0038] The following will further describe the present application in detail with reference to the attached Figures 1 to 7 drawings.

[0039] The present application provides a support base, including: a fixed base 1, a tie rod joint 2, and a support base body 3.

[0040] Specifically, as Figure 1 shown, the fixed base 1 includes a bottom positioning plate, a top joint, and a plurality of side ribs 103 disposed between the bottom positioning plate and the top joint. Among them, the bottom positioning plate is fixed on the second floor through a connecting member; a top joint connection hole 102 is provided on the top joint, and the top of the top joint has an upper top surface 104; the plurality of side ribs 103 include a first side rib, a second side rib, a third side rib, and a fourth side rib. The first side rib and the third side rib are symmetrically arranged, the second side rib and the fourth side rib are symmetrically arranged, and a side joint is provided on the second side rib.

[0041] In a preferred embodiment of the present application, four positioning plate connection holes 101 are provided on the bottom positioning plate, and the four positioning plate connection holes 101 of the bottom positioning plate are fixed on the second floor through bolts. The bottom positioning plate adopts a rectangular structure, and a weight reduction hole is provided at its central position. Preferably, a side joint connection hole 105 is provided on the side joint for connecting the fixed base 1 with other structures.

[0042] As Figure 2As shown, the tie rod joint 2 includes a tie rod joint head, on which a tie rod joint connection hole 201 is provided. The tie rod joint head is located on one side close to the fourth side rib, and the tie rod joint connection hole 201 is aligned with the top joint connection hole 102.

[0043] In a preferred embodiment of the present application, the tie rod joint 2 includes two tie rod joint heads, on which tie rod joint connection holes 201 are provided. The two tie rod joint heads are sleeved on the fourth side rib, and the tie rod joint connection holes 201 are aligned with the top joint connection holes 102. When connecting, the tie rod joint connection holes 201 and the top joint connection holes 102 are concentrically connected.

[0044] As Figure 3 shown, the support base body 3 includes two symmetrically arranged support arms and an inner rib 306 connecting the two support arms. Support arm long circular holes 301 are provided on both support arms. Straight clamping legs 304 and bent clamping legs 305 are provided at the bottoms of the two support arms, and the bent clamping legs 305 are located on the side close to the side joint. A support base lower groove 302 is formed between the straight clamping leg 304 and the bent clamping leg 305.

[0045] In a preferred embodiment of the present application, the support base body 3 is U-shaped, and the top of the support base body 3 has a support surface for supporting the upper floor. In this embodiment, it is preferred to provide an inner rib connection hole on the inner rib 306. In addition, the length of the straight clamping leg 304 is greater than the length of the bent clamping leg 305.

[0046] For the support base of the present application, the fixed base 1, the tie rod joint 2, and the support base body 3 are hinged by a rotating shaft passing through the top joint connection hole 102, the tie rod joint connection hole 201, and the support arm long circular hole 301. As Figures 4 - 5 shown, in the working state, the lower bottom surface 303 of the inner rib 306 is pressed against the upper top surface 104 of the top joint, and the support base lower grooves 302 of the two support arms are respectively clamped on the first side rib and the third side rib. As Figures 6 - 7 shown, in the non-working state, the support base body 3 is pulled up until the center of the lower part of the support arm long circular hole 301 is concentric with the tie rod joint connection hole 201, and the support base body 3 is rotated around the rotating shaft towards the side close to the side joint until the side surface of the inner rib 306 abuts against the side joint.

[0047] When the support base of the present application is adjusted from the working state to the non - working state, the support base body 3 needs to be pulled upward until the center of the lower part of the long circular hole 301 of the support arm is concentric with the connection hole 201 of the pull rod joint. Then, the support base body 3 is rotated around the rotating shaft towards the side close to the side joint. Since the lengths of the straight clamping leg 304 and the bent clamping leg 305 of the support base body 3 are different, the straight clamping leg 304 restricts the rotation direction of the support base body 3, and the support base body 3 can only rotate towards the direction of the bent clamping leg 305 until the side surface of the inner rib 306 of the support base body 3 contacts the edge of the side joint. In the non - working state, the support base can provide space for the normal use of the pull rod joint 2.

[0048] The present application provides a support base, aiming to provide a support when multiple - layer floors are stacked, to prevent the upper - layer floor from pressing on the pull rod joint 2 of the lower - layer floor and causing the pull rod joint 2 to break. Among them, the support base includes: a fixed base 1, a pull rod joint 2, and a support base body 3. The bottom positioning plate of the fixed support 1 is fixed on the second - layer floor, and the fixed base 1, the pull rod joint 2, and the support base body 3 are connected together through a rotating shaft. When multiple - layer floors are stacked, the pull rod joint 2 is biased to one side, the support base body 3 straddles the fixed base 1, and the upper - layer floor is press - connected to the support surface at the top of the support base body 3, protecting the pull rod joint 2 from damage; in the working state of the second - layer floor, the support base body 3 is lifted and biased to one side, providing a working space for the pull rod joint 2 to stand up without affecting the normal use of the pull rod joint 2.

[0049] The above - mentioned is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the technical field within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
