DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The protective system used in the automated production environment usually adopts single-sided sliding doors and double-sided sliding doors. The double-sided sliding door is a symmetrical design of the single-sided sliding door. In this embodiment, one side sliding door of the double-sided sliding door is used for illustration, and the other side sliding door is a completely symmetrical design.

[0028] like Figures 1 to 3 As shown, the upper frame profile 1, the lower frame profile 2 and the side frame profile 3 are enclosed to form a rectangular door frame, and the door panel 4 is horizontally translated in the door frame through the upper track assembly and the lower track assembly. In this embodiment, it is a double-sided sliding door structure, and the two sides of the double-sided sliding door are completely symmetrically designed. The two door panels 4 can be independently translated in their respective tracks. This embodiment is described with one side of the double-sided sliding door, and the completely symmetrical structure of the other side is not described in detail.

[0029] like Figure 3 and Fig.10 As shown, the upper track assembly includes an upper track profile 5, an upper guide bar 6 and an upper door panel connecting piece 7. The lower end of the upper frame profile 1 is fixedly connected to the upper end of the upper track profile 5. The upper track profile 5 is provided with an upper guide bar 6. The upper end of the upper door panel connecting piece 7 is matched and connected with the upper guide bar 6. The lower end of the upper door panel connecting piece 7 is fixedly connected to the upper end of the door panel 4. The length direction of the upper guide bar 6 is horizontal. The upper guide bar 6 cooperates with the upper end of the upper door panel connecting piece 7 to guide the horizontal movement of the door panel 4. The track assembly includes a lower track profile 8, a pulley 9 and a lower door panel connecting member 10. The lower end of the lower track profile 8 is fixedly connected to the upper end of the lower frame profile 2, the lower end of the door panel 4 is fixedly connected to the upper end of the lower door panel connecting member 10, and the lower end of the lower door panel connecting member 10 is freely connected to a pulley 9 through an axis. There can be several pulleys 9, and the pulley 9 is a vertical pulley 9 that can rotate freely in the vertical direction. The lower end of the pulley 9 abuts against the upper end of the lower track profile 8 and slides horizontally in the lower track profile 8.

[0030] In some embodiments, Figures 4 to 6 As shown, the upper track profile 5 has a first opening portion 501 facing downward, and a guide bar accommodating portion 5011 opening downward is provided in the first opening portion. The upper end of the upper guide bar 6 is arranged in the guide bar accommodating portion 5011, and the upper end of the upper door panel connecting member 7 is a groove portion 701 opening upward, and the lower end of the upper guide bar 6 is placed in the groove portion 701. The upper guide bar 6 and the groove portion 701 cooperate with each other to play an auxiliary guiding role, thereby preventing the door panel 4 from being forced out of the track during horizontal movement. The upper end portion of the upper door panel connecting member 7 is also placed in the first opening portion 501, and the upper guide bar 6 and the groove portion 701 are covered on both sides to prevent dust and debris in the environment from entering between the upper guide bar 6 and the groove portion 701.

[0031] In some embodiments, Figures 4 to 7 As shown, the upper rail bar 6 includes a connecting portion 601 at the upper end and an upper rail portion 602 at the lower end, the connecting portion 601 and the upper rail portion 602 are connected in sequence, the shape of the connecting portion 601 matches the shape of the rail bar accommodating portion 5011, the connecting portion 601 can be inserted into the rail bar accommodating portion 5011 along its length direction, and is limited in the rail bar accommodating portion 5011, that is, the upper rail bar 6 and the upper track profile 5 can be connected without additional connecting parts, the installation is simple, and the upper rail bar 6 can be replaced without removing the door panel 4. The upper rail portion 602 is placed in the first opening portion 501 and partially placed in the groove portion 701, and cooperates with the groove portion 701 to play a guiding role, and at the same time, the first opening portion 501 and the internal upper rail portion 602 and the groove portion 701 play a dust protection role.

[0032] In some embodiments, Figures 9 and 10 As shown, the upper surface of the lower track profile 8 has an upward second opening portion 801, and an upwardly protruding lower guide rail portion 8011 is provided in the second opening portion 801, and the top of the lower guide rail portion 8011 is an arc-shaped protrusion, and the circumference of the pulley 9 has an inwardly recessed pulley groove 901, and the pulley groove 901 abuts against the lower guide rail portion 8011, and rolling friction is performed between the lower guide rail portion 8011, thereby improving the smoothness of the horizontal movement of the door panel 4, and the lower end of the pulley 9 is placed in the second opening portion 801, and the second opening portion 801 has a covering effect on the lower end of the pulley 9 and both sides of the lower guide rail portion 8011, thereby preventing dust and debris in the environment from entering between the upper pulley 9 and the lower guide rail portion 8011.

[0033] In some embodiments, Figures 4 to 8 As shown, dustproof strips 11 are provided on both sides of the upper door panel connecting piece 7. The dustproof strips 11 are made of soft PVC material. The dustproof strips 11 on both sides are respectively abutted against the inner walls on both sides of the first opening portion 501, thereby further forming a closed environment between the upper guide rail strip 6 in the first opening portion 501 and the groove portion 701 of the upper door panel connecting piece 7, thereby achieving a further dustproof effect.

[0034] In some embodiments, Figures 4 to 8 As shown, the dust strip 11 includes an abutting portion 1101 and a clamping portion 1102 which are connected in sequence. The clamping portion 1102 can be docked and clamped with the preset clamping hole at the upper door panel connecting member 7 on the corresponding side. The abutting portion 1101 abuts against the inner walls of both sides of the first opening portion 501 outward relative to the upper door panel connecting member 7. The abutting portion 1101 is an arc surface, so that the abutting surface and the inner wall of the first opening portion 501 are connected by a line, which reduces the contact area and thus reduces the friction, thereby improving the smoothness of the translation, and the dust strip 11 is easy to disassemble and replace due to the clamping connection.

[0035] In some embodiments, Figures 4 to 7 As shown, the upper guide rail portion 602 and the groove portion 701 are arranged at intervals. During the normal horizontal movement of the door panel 4, there is no contact between the upper guide rail portion 602 and the inner wall of the groove portion 701. The upper guide rail portion 602 serves to guide the door panel 4 when the door panel 4 tilts, that is, when there is a tendency to deviate. During the normal horizontal movement, the dustproof strip 11 is guided by the contact between the inner wall of the first opening portion 501, which effectively prevents friction between the upper guide rail portion 602 and the upper door panel connector 7, prevents dust from being generated, and is suitable for a clean environment.

[0036] During the installation process of the present application, first fix the upper track profile 5 and the lower track profile 8 to the corresponding upper frame profile 1 and the lower frame profile 2 respectively, fix the upper door panel connecting piece 7 and the lower door panel connecting piece 10 to the upper and lower ends of the door panel 4 respectively, then insert the upper guide rail 6 into the upper track profile 5, lift the door panel 4 and slightly tilt the groove portion 701 of the upper door panel connecting piece 7 to face the upper guide rail 6, then slightly lift and erect the door panel 4, finally face the pulley 9 at the lower door panel connecting piece 10 to face the lower guide rail portion 8011, and the installation is completed.
