[0014] An elevator door slider comprises the above-mentioned fixing structure.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The clamping plate is clamped in the installation groove opened on the elevator door, so as to preliminarily fix and install the entire device, and then the hexagon socket bolt is sleeved in the installation hole through the installation hole opened on the installation plate and the threaded end is threadedly connected with the elevator door, so as to fix the installation plate on the elevator door. At this time, the limit plate is inserted between the fixed plates, and the clamping column plates fixedly connected on both sides are slidably inserted into the non-threaded ends of the hexagon socket bolts, and at the same time, the iron column fixedly connected to one side of the limit plate is inserted into the magnetic attraction ring in the limit hole, and the magnetic attraction ring magnetically attracts the iron column to limit it, so as to preliminarily fix the limit plate, so that the clamping column plate preliminarily limits the hexagon socket bolt, and then the anti-loosening bolt is sleeved in the limit plate, and the friction block and the spring plate ring are sleeved on the non-threaded end of the anti-loosening bolt, and the anti-loosening bolt is twisted to make it first threadedly connected with the installation plate, and then threadedly connected with the connection hole reserved for the elevator door, so as to fix the limit plate, and further limit the clamping column plate to the hexagon socket bolt.

[0017] 2. In the process of twisting the anti-loosening bolt, the friction block will be pressed, and the friction block will squeeze the spring leaf ring, which will be deformed by force, and then the spring leaf ring will produce reverse elastic force, which will reversely support the anti-loosening bolt, so that the connection between the anti-loosening bolt and the mounting plate is tighter. The friction block can increase the friction between the anti-loosening bolt and the anti-loosening bolt, thereby preventing the anti-loosening bolt from loosening, making the installation of the limit plate more stable, and then the column plate can fix and limit the hexagon socket bolt, thereby avoiding loosening of the connection and reducing safety hazards.

[0018] 3. The slider is fixedly installed on the connecting steel plate. The strength of the connecting steel plate is high, which can avoid the deformation of the door slider and the lower part of the door panel as much as possible, causing the door slider to fall out, affecting the safety of elevator operation and causing safety hazards. At the same time, a fixed shaft is fixed in the connecting steel plate, and rollers are rotatably connected at both ends of the fixed shaft. The rollers facilitate the auxiliary sliding of the slider during the sliding process, which is conducive to the smooth opening and closing of the elevator door. BRIEF DESCRIPTION OF THE DRAWINGS
