[0013] Beneficial effects of the utility model:

[0014] The utility model discloses a basement top plate large plate arm structure. The utility model can place the arm plate at the junction of the top plate and the support column, align the first positioning block with the horizontal insertion hole, align the second positioning block with the longitudinal insertion hole, push one side of the arm plate so that the first positioning block is completely inserted into the horizontal insertion hole, and then hold the reinforcing rod to push it to rotate along the rotation axis. When the reinforcing rod is deflected by a certain angle, its top will contact the interference groove, and exert a vertical action on the inner wall of the interference groove, so that the second positioning block can enter the longitudinal insertion hole. When the second positioning block is completely inserted into the longitudinal insertion hole, The limiting groove arranged at one end of the reinforcing rod can just be deflected to the side of the positioning pin, and the strong magnet built into the limiting groove sucks the positioning pin into the limiting groove, thereby locking the position of the reinforcing rod and the second positioning block. This state can be shown in the figure with reference to the figure, so that the installation of the armpit structure can be completed quickly. The connection between the armpit plate and the reinforcing rod forms a triangle, which has high stability. At the same time, after the installation of the armpit plate, the inner side thereof has a large cavity, which can accommodate the installation requirements of various types of pipelines, fully ensuring the utilization rate of the space, and the overall installation process is simple, and the construction period is effectively shortened.

[0015] The utility model discloses a basement top plate large plate armpit structure. When the reinforcing rod is deflected, the steel ball rotates together with the synchronous sleeve, that is, the steel ball has a tendency to move from the R end to the L end, so that the steel ball exerts a certain pulling force on the steel rope. The pulling force directly drives the extrusion block to slide on the positioning rod, and the sliding direction is toward the end face of the first positioning block. At this time, the extrusion block deflects the extrusion limit plate until the outer wall of the limit plate is close to the inner wall of the conical groove. In this way, the lateral position of the first positioning block relative to the lateral plug hole can be locked, thereby further increasing the overall armpit firmness of the utility model.

An axle plate 1 is placed at the junction of the basement top plate and the support column. The cross section of the axle plate 1 is L-shaped. An axle seat 2 is welded to the bottom of the short side of the axle plate 1. A rotating shaft 3 is arranged in the built-in center position of the axle seat 2. A synchronous sleeve 4 is sleeved on the outer wall of the rotating shaft 3. A reinforcing rod 5 is welded to the outer wall of the synchronous sleeve 4. A first positioning block 14 is welded to the side wall of the short side of the axle plate 1, and The first positioning block 14 is inserted into the transverse insertion hole 12, a through hole 13 is provided inside the long side of the axilla plate 1, and a second positioning block 15 is inserted into the through hole 13, and the blind end of the second positioning block 15 is inserted into the longitudinal insertion hole 11, and a resistance groove 16 is provided at the head of the second positioning block 15, and a positioning pin 17 is inserted at the center of the inner wall of the resistance groove 16, and the positioning pin 17 is magnetic, and a limiting groove 51 is provided at the head position of the reinforcing rod 5, and the shape and size of the limiting groove 51 are the same as The cross-section of the positioning pins 17 is the same, and a strong magnet is embedded in the inner wall of the limiting groove 51. During specific operation, the armpit plate 1 is placed at the junction of the top plate and the support column, and the first positioning block 14 is aligned with the horizontal insertion hole 12, and the second positioning block 15 is aligned with the longitudinal insertion hole 11. Push one side of the armpit plate 1 so that the first positioning block 14 is completely inserted into the horizontal insertion hole 12, and then hold the reinforcing rod 5 and push it to rotate along the rotating axis 3. When the reinforcing rod 5 is deflected by a certain angle, its top will contact the interference groove 16, and the inner wall of the interference groove 16 is exerted in the vertical direction, so that the second positioning block 15 can enter the longitudinal insertion hole 11. When the second positioning block 15 is completely inserted into the longitudinal insertion hole 11, the limiting groove 51 set at one end of the reinforcing rod 5 can just be deflected to the side of the positioning pin 17, and the strong magnet built into the limiting groove 51 sucks the positioning pin 17 into the limiting groove 51, and the positions of the reinforcing rod 5 and the second positioning block 15 are locked. This state can be referred to Figure 4 As shown, the installation of the axil structure can be completed quickly. The axil plate 1 and the reinforcing rod 5 are connected to form a triangle, which has high stability. At the same time, after the axil plate 1 is installed, the inner side thereof has a large cavity, which can accommodate the installation requirements of various types of pipelines, fully ensuring the utilization rate of the space, and the overall installation process is simple, and the construction period is effectively shortened;

When the reinforcing rod 5 is not installed, the initial position of the steel ball 146 is located at Figure 3 Near the middle R end, when the reinforcing rod 5 is deflected, the steel ball 146 rotates together with the synchronous sleeve 4, that is, the steel ball 146 has a tendency to move from the R end to the L end, so that the steel ball 146 exerts a certain pulling force on the steel rope 145, and the pulling force directly drives the extrusion block 142 to slide on the positioning rod 141, and the sliding direction is toward the end face of the first positioning block 14. At this time, the extrusion block 142 deflects the extrusion limit plate 143 until the outer wall of the limit plate 143 is close to the inner wall of the tapered groove 121, so that the lateral position of the first positioning block 14 relative to the lateral plug hole 12 can be locked, further increasing the overall armpit firmness of the utility model.
