[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model embodiment discloses a novel stair railing for a transformer substation.

[0024] Reference Figure 1-3 A new type of stair railing for a substation includes a stair body 3 and a railing body 1. The railing body 1 is arranged above the stair body 3. A plurality of mounting rods 2 are fixedly arranged on one side of the railing body 1 close to the stair body 3. A plurality of mounting plates 4 are pre-embedded inside the stair body 3. Both sides of the lower surface of the mounting plate 4 are fixedly provided with "J"-shaped rods 9, which can improve the stability of the connection between the mounting plate 4 and the stair body 3. A mounting tube 5 is fixedly arranged on the upper side of the mounting plate 4. The lower end of the mounting rod 2 is plugged into the corresponding mounting tube 5. Through grooves are provided on both sides of the mounting tube 5. A card block 8 is slidably provided inside the through groove. Card slots are provided on both sides of the lower end of the mounting rod 2. One end of the card block 8 is carded with the corresponding card slot, and a groove is provided at the bottom of the through groove.

[0025] Reference Figure 1-3 A limiting mechanism for limiting the block 8 is arranged on the outer side of the mounting tube 5, and the limiting mechanism includes an internal thread ring 7 and a limiting ring 6. A thread is provided on the outer wall of the mounting tube 5, and the internal thread ring 7 is threadedly sleeved on the outer wall of the mounting tube 5. The limiting ring 6 is fixedly arranged on the lower side of the internal thread ring 7. The limiting rings 6 are arranged to abut against the outer sides of the blocks 8 on both sides. A slope is provided on the side of the block 8 close to the limiting ring 6, so that the limiting ring 6 can squeeze the block 8 toward the inner side of the slot.

[0026] Reference Figure 1-3 A reset mechanism for driving the block 8 to reset is arranged inside the groove, and the reset mechanism includes a slider 10 and a spring 12. A slide rod 11 is fixedly arranged inside the groove, and the slider 10 is movably sleeved on the rod wall of the slide rod 11, and the spring 12 is movably sleeved on the rod wall of the slide rod 11. One end of the spring 12 is fixedly connected to the side of the slider 10 away from the limit ring 6, and the other end of the spring 12 is fixedly connected to the inner wall of the groove. Both sides of the slider 10 are in conflict with the inner wall of the slide groove, so that the slider 10 cannot rotate, that is, it can slide stably.

[0027] The inner threaded ring 7 is then rotated to drive the limiting ring 6 to move downward until the limiting ring 6 blocks the outer sides of the blocking blocks 8 on both sides, that is, the blocking blocks 8 can be limited, and the installation of the railing body 1 is completed. The operation is convenient, time-saving and labor-saving. The inner threaded ring 7 is rotated in the opposite direction to make the limiting ring 6 move away from the outer sides of the blocking blocks 8. At this time, the elastic force of the spring 12 pushes the slider 10 to reset, that is, the blocking block 8 moves and resets, that is, the blocking block 8 is separated from the slot, that is, the limit between the mounting rod 2 and the mounting tube 5 is released, and the mounting rod 2 can be pulled out of the mounting tube 5, that is, the disassembly of the railing body 1 is completed, and the maintenance and repair of the railing body 1 is convenient.

[0028] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
