The outer wall of the second threaded post 8 is threadedly connected with a limiting sleeve 10, and the bottom of the limiting sleeve 10 is in contact with the top of the rotating shaft 5.
[0024] The effect achieved by the whole embodiment 1 is that the rotating shaft 5 with the two bearing barrels 6 is placed in the placing groove 7, since the first threaded column 3 is installed at the bottom of the inner wall of the two installation grooves 2, then the installation block 4 installed at both ends of the rotating shaft 5 is sleeved on the two first threaded columns 3, and at this time the rotating shaft 5 is also sleeved on the second threaded column 8 installed at the bottom of the inner wall of the placing groove 7, then through the action of the two nuts 9, it is rotated downward along the two first threaded columns 3 until the bottom of the two nuts 9 is in contact with the top of the two installation blocks 4, so as to limit the two installation blocks 4 in the two installation grooves 2, and limit the rotating shaft 5 and the two bearing barrels 6 on the corner bearing seat 1, at the same time, the limiting cylinder 10 is screwed on the second threaded column 8 and the bottom of the limiting cylinder 10 is in contact with the top of the rotating shaft 5, which reinforces the stability of the rotating shaft 5 and the two bearing barrels 6 installed on the corner bearing seat 1, and when one of the barrels is damaged or both of the barrels are damaged, the whole double-shaft double-hole corner bearing does not need to be discarded, which reduces the problem of resource waste, thereby improving the practicability of the double-shaft double-hole corner bearing.
[0025] Embodiment 2: as shown in Figures 2-4 The top of the corner bearing seat 1 is provided with two strip-shaped grooves 11, the inner wall of the two strip-shaped grooves 11 is fixedly installed with a spring 12 on one side, the outer wall of the two springs 12 is fixedly installed with a T-shaped plug block 13 on one side, and the outer surface wall of the two T-shaped plug blocks 13 is movably embedded in the inside of the two strip-shaped grooves 11, the top of the two T-shaped plug blocks 13 is fixedly installed with a shielding plate 14, the top of the corner bearing seat 1 is provided with two positioning grooves 15, the inner surface wall of the two positioning grooves 15 is movably inserted with a positioning strip 16, the top of the two positioning strips 16 is fixedly installed with a dustproof plate 17, the bottom of the two dustproof plates 17 is fixedly installed with a rectangular block 18, the outer wall of the two rectangular blocks 18 is provided with a limiting insertion hole 19 on one side, and the outer surface wall of the two T-shaped plug blocks 13 is movably inserted in the inside of the two limiting insertion holes 19.
[0026] The effect achieved by the whole embodiment 2 is that when the rotating shaft 5 and the two bearing barrels 6 are installed on the corner bearing seat 1, the two T-shaped plugs 13 are moved by the two shielding plates 14, and at the same time, the two T-shaped plugs 13 press the springs 12 installed inside the two strip-shaped grooves 11. When the two T-shaped plugs 13 move a distance, the two dustproof plates 17 are placed in the corresponding position through the action of the two positioning grooves 15 and the two positioning strips 16, and the rectangular blocks 18 installed at the bottom of the two dustproof plates 17 can be inserted inside the two strip-shaped grooves 11. Since the outer wall of the two rectangular blocks 18 is provided with a limiting insertion hole 19 on one side, then the two shielding plates 14 are loosened, and under the action of the two springs 12, the two T-shaped plugs 13 pass through the two limiting insertion holes 19 and are inserted inside the corner bearing seat 1, thereby installing the two dustproof plates 17 above the two installation grooves 2, effectively preventing dust or foreign matter from accumulating on the two first threaded columns 3 and the two nuts 9, and improving the smoothness of subsequent disassembly and assembly.

[0027] Working principle: first, the rotating shaft 5 is sleeved on the second threaded column 8 installed in the placement groove 7, and at this time, the mounting blocks 4 installed at both ends of the rotating shaft 5 are sleeved on the two first threaded columns 3, and then the two nuts 9 are threadedly connected to the two first threaded columns 3, and at the same time, the limiting cylinder 10 is threadedly connected to the second threaded column 8, thereby limiting the rotating shaft 5 and the two bearing barrels 6 in the two installation grooves 2, the placement groove 7 and the corner bearing seat 1. Then, the two T-shaped plugs 13 are moved by the two shielding plates 14 to press the two springs 12, and then under the action of the two positioning grooves 15 and the two positioning strips 16, the two dustproof plates 17 are located in the corresponding position, and the two rectangular blocks 18 installed at the bottom thereof are inserted into the two strip-shaped grooves 11. At this time, the two shielding plates 14 are loosened, and under the action of the two springs 12, the two T-shaped plugs 13 pass through the limiting insertion holes 19 on the two rectangular blocks 18 and are inserted into the corner bearing seat 1, thereby limiting the two dustproof plates 17 above the two installation grooves 2, avoiding dust or foreign matter from falling into the installation grooves 2 and affecting the smoothness of subsequent disassembly and assembly. In general, by facilitating the disassembly and assembly of the rotating shaft 5 and the two bearing barrels 6, when one barrel is damaged or both barrels are damaged, the entire double-shaft double-hole corner bearing does not need to be discarded, which increases the recycling of resources and reduces the problem of resource waste, thereby improving the practicality of the double-shaft double-hole corner bearing.
