Detailed Description

As shown in fig. 1 and fig. 2, the chassis frame of the plug-in concrete vibrator of the present invention includes a base 1, a triangular frame type pillar 3, a bearing seat 5, an upper arc-shaped snap ring 7 and a lower arc-shaped snap ring 6. In the utility model, the base 1 is a circular column. The base 1 is provided with an annular groove 2 along the top surface of the circular column. The upper ends of the triangular support posts 3 are jointly rigidly fixed with a bearing seat 5. The lower ends of the three legs 3.1 of the triangular support 3 are respectively connected with a rolling pulley 4 through a pulley seat (see figure 3). The rolling pulleys 4 on the three legs 3.1 are uniformly distributed and seated in the annular groove 2 of the base 1 and are connected with the annular groove 2 in a sliding way. Three minor arc limiting insertion blocks 12 with the same length are arranged in the annular groove 2. The motion-limiting insertion block 12 is inserted into the annular groove 2, and in a use state, the motion-limiting insertion block 12 is inserted into the annular groove 2. Three stop blocks 12 inserted into the annular groove 2 are each placed between two adjacent legs 3.1 and have their ends in abutting connection with the adjacent legs 3.1. The lower snap ring 6 is rigidly fixed on the bearing seat 5. The lower snap ring 6 is connected with a finished bolt 8 and an upper snap ring 7. The bottom of the bearing seat 5 is provided with a support rod 9 at the center of three support legs 3.1 distributed on the circumference. The external thread is arranged on the external wall surface of the lower part of the supporting rod 9.
