Description
Technical Field
The invention relates to a sliding door fitting, in particular to a magnet section bar fastening structure of an electric door of a sliding door, belonging to the manufacturing technology of architectural decoration hardware fittings.
Background
The existing automatic opening sliding door is opened by adopting transmission components such as chains, has large noise and high failure rate, so that the automatic door driven by the linear motor appears in the market. In the existing linear motor automatic door, the magnets are driven by electromagnetic blocks to obtain power, but a plurality of magnets are adhered to a fixed plate by glue. However, on the one hand, the fixing strength of the glue bond itself is insufficient, and as the service time increases, the glue ages, resulting in a further decrease in the bonding strength between the magnet and the plate, and a gap between the magnet and the fixing plate. In addition, the in-process that the door body was slided, magnet can rock, further influences other adjacent magnet, and the magnetic field intensity that the synergism of a plurality of magnets will be along with the decline, and the sensor that appears the door senses when needs to open the door, the door nevertheless is not opened or the condition of stopping midway, therefore just need frequent re-bonding repair, and when bonding repair, repair when a certain magnet, still need to go down simultaneously adjacent several magnet, it is laborious to waste time, the cost is very high, very inconvenient. On the other hand, when the plurality of magnets are bonded by using the glue, the bonding work per se is complex, the glue is firstly coated on the fixed plate or/and each adjacent magnet, and then the plurality of magnets are sequentially bonded on the fixed plate, and as the mechanical structure of the linear motor has higher requirements on the mounting height of the plurality of magnets and the close contact between the adjacent magnets, the common worker is generally difficult to be qualified; in addition, when the bonding exists, glue can penetrate into between two adjacent magnets more or less, gaps exist between the adjacent magnets, the existence of the gaps can cause the synergistic effect of a plurality of magnets, the strength of a formed magnetic field is reduced, and accordingly driving force to a door is affected.

Unlike traditional paste magnet through glue on the fixed plate, this application is through utilizing the fastener to press from both sides tight between fixed plate and press wall with a row of magnet to can directly be with magnet to the fixed plate on, wholly adopt mechanical fixed connection, the installation is more firm, and is more convenient, adjacent because need not to need not glue between magnet and the fixed plate, also not have the problem that the collaborative magnetic field intensity that leads to because of glue descends between the adjacent magnet.
Further, the thickness of the fixing plate is greater than or equal to 1.5mm. The fixed plate with the thickness being greater than 1.5mm can form a synergistic effect by a plurality of magnets, and the magnetic flux formed by the magnets for many times is increased, so that when the linear motor mechanical structure drives the door leaf to move, the power is stronger, larger power can be obtained by smaller electric energy input, and the device is more energy-saving and environment-friendly.
Further, the thickness of the fixing plate is 2.5mm. When the plate thickness is 2.5mm, the magnet and the plurality of magnets form the best synergistic effect.
Further, the fixing plate is an iron plate.
Further, the pressing wall is formed by bending two side walls of the magnet row accommodating groove towards the middle. The press wall is integrally formed with the main body, so that the assembly of parts can be reduced.
Further, the bottom of the magnet row accommodating groove is provided with an opening through which the fastening piece passes, and in the fastening state, the fastening piece passes through the opening to be abutted with the fixing plate. The fastener is matched with the open hole, and the fastener is directly abutted to the fixed plate, so that the magnet row can be effectively clamped between the fixed plate and the press wall by the fastener.
Further, a step part is arranged on the outer side of the magnet in the magnet row, and the step part is matched with the press wall. The design of the magnet step part ensures that the magnet is accurately positioned in the magnet row accommodating groove, thereby limiting the movement of the magnet in the width direction of the accommodating groove and avoiding the phenomenon that the magnet is separated from the position.
Further, the fastener is a threaded fastener. The fastening piece gradually enhances the abutting force to the fixed plate by rotating the threaded fastening piece, so that the magnet row is gradually clamped between the press wall and the fixed plate.
Further, the bottom of the magnet row accommodating groove is also provided with a fastener anti-loosening structure. The loosening structure avoids loosening of the fastener after the magnet is fixed.
Further, the middle part of the main body is hollow, and the other side of the main body is also provided with a slot for installing an end cover. The openings at the two ends of the groove are closed by the end covers, so that the fastening effect of the magnet can be guaranteed, the magnet is prevented from shaking in the length direction of the groove, and the magnet and the pressing wall are provided with mutually matched steps, so that the installation can be facilitated, and the fixing effect can be improved.
