Description

Safety door structure Technical Field The utility model relates to the technical field of product processing safety, in particular to a safety door structure. Background In the field of production and assembly, the safety door is used as an entrance of a safety protection structure, the rationality and the convenience of the safety door can directly influence the production process, and at present, most of workshops adopt a safety door in a hinge turnover type mode, and the opening and closing movement of the safety door is completed by means of opening and closing of a hinge. The safety door with the structure has the most wide application because of simple structure and convenient disassembly and assembly. In addition, a pulley type safety sliding door is adopted, a pulley is arranged at the bottom of the safety door to provide supporting force for the safety door, and a guide pillar and the pulley are arranged to guide the safety door so as to enable the safety door to move and open. But the hinged safety door needs bigger working space, can meet the conditions of interference with other equipment or inconvenient opening, and the like, the installation of the translational pulley moving door is more complex, a guide mechanism is required to be independently designed to ensure on-track movement of the translational pulley moving door, and meanwhile, the translational pulley moving door is easy to be influenced by ground conditions. Disclosure of utility model Accordingly, in order to solve the above-mentioned drawbacks, the present utility model provides a safety door structure comprising: the first sliding rails are provided with two groups, the two groups of the first sliding rails are arranged in parallel up and down, and the two groups of the first sliding rails are fixed on the same plane; The first sliding door is in sliding fit with the two groups of first sliding rails; the second movable door is arranged in a staggered manner corresponding to one side of the first movable door away from the first sliding rail. The utility model adopts the double slide rail structure which is arranged in parallel up and down, and solves the problem of equipment interference caused by the large opening space required by the hinge type safety door. Through the synchronous direction of upper and lower double track to first dodge gate, second dodge gate, overcome vibrations and noise problem that traditional translation door single-point support led to, improve the operational stability. Because whole emergency exit structure is unsettled by double track to the dodge gate to reduced the influence and the ground roughness restriction that ground foreign matter moved the door body, improved and opened and close the reliability, through setting up two sets of dislocation arranged's dodge gate, so that the dodge gate can follow two-way opening, improved the flexibility of use of emergency exit structure. Further, the first movable door and the second movable door are in sliding fit with the first sliding rail through pulleys; The pulley comprises: The first pulley is arranged at the upper part and the lower part of the first sliding door, which are close to the side surface of the first sliding rail; The second pulley is connected with the second sliding door through a connecting plate, and the connecting plate extends from one side, away from the first sliding rail, of the first sliding door to one side, close to the first sliding rail, of the first sliding door by bypassing the upper part or the lower part of the first sliding door. The second pulley is connected with the second movable door by the connecting plate which bypasses the upper part or the lower part, so that the first movable door and the second movable door are ensured to keep the same height, and meanwhile, the movement interference caused by sliding the first movable door or the second movable door is avoided. Further, limiting grooves are formed in the wheel surfaces of the first pulley and the second pulley; The first sliding rail is provided with a guide groove, the second pulley is corresponding to the guide groove, the upper side wall and the lower side wall of the guide groove are respectively provided with a second limiting part and a first limiting part which are protruded downwards, the limiting groove of the second pulley is clamped on the second limiting part, and the limiting groove of the first pulley is clamped on the first limiting part. Through the nested cooperation of the limit part of upper and lower first slide rail and the limit groove of pulley, improve the installation positioning accuracy of dodge gate, simultaneously, limit groove and limit part's joint structure form the motion restriction, the risk of motion skew. Further, an opening is formed in a preset position of the first moving door and/or the second moving door, a third moving door is arranged at the opening position, the third moving door is arranged in a staggered mode
