[0036] Example 1

[0037] See also Figure 1-5 , an embodiment provided by the present utility model is as follows:

[0038] An anti-slip rotatable and translational emergency evacuation automatic door comprises a top frame 3 and a bottom frame 1 which are parallel to each other and sandwich a door panel 4.

[0039] Support piles 2 are vertically arranged on both sides of the top of the bottom frame 1. The top of the support piles 2 is connected to the top frame 3 parallel to the bottom frame 1. The bottom surface of the top frame 3 is abutted against a number of door panels 4. The support piles 2 are directly provided with a number of door panels 4.

[0040] The upper and lower ends of the door panels 4 are provided with fixing plates 5 for connecting the door panels to the top frame 3 or the bottom frame 1. A positioning ring 6 is connected to one side of the upper or lower end surface of the fixing plate 5. A vertical cylindrical connecting rod 8 is sleeved in the positioning ring 6. A fixing screw 7 is arranged horizontally through the positioning ring 6 and the connecting rod 8. A connecting rod 8 is sleeved on the outer wall of one end of the fixing screw 7. The connecting rod 8 is movably connected to a bearing 9 at one end facing upward. A limiting slider 10 is connected to the upper end of the bearing 9. The limiting slider 10 is slidably set in the groove of the top frame 3 to form a bearing slider combination structure; this bearing slider combination structure can drive the door panel 4 at the lower end to slide or rotate as needed, so that the door panel 4 can slide in the groove of the top frame 3 through the limiting slider 10 without falling off, and when the door panel 4 needs to rotate, the bearing 9 is used to make the door panel 4 drive the connecting rod 8 to rotate without affecting the limiting slider 10.

[0041] The slide groove of the top frame 3 is set as a flat groove with a straight profile ( Figure 4 ) and L-shaped corner grooves that are perpendicular to each other ( Figure 3 ), the flat groove is set in the middle of the length direction, and corner grooves are set at both ends of the length direction. One end of the outer notch of the corner groove is blocked) to prevent the limit slider 10 from driving the door panel 4 to fall off.

[0042] The chute of the bottom frame 1 is similar to the chute of the top frame 3, except that the notch is upwardly facing. Thus, the door panel can rotate through the bearing 9 and be simultaneously constrained in the chute of the bottom frame 1 and the top frame 3.

[0043] The internal material of the door panel 4 is existing technology and can be purchased on the market. It is not a technical protection point of this application, so no further explanation will be made.

[0044] Furthermore, the positioning ring 6 is sleeved on one side of the outer surface of the vertically arranged connecting rod 8, and four groups of door panels 4 are provided and inserted between the base frame 1 and the top frame 3, so that the upper and lower ends of the door panels 4 can be positioned through the base frame 1 and the top frame 3.

[0045] Furthermore, a through hole is opened on the surface of the positioning ring 6, and a threaded hole is opened on the horizontal side of the connecting rod 8. The through hole and the threaded hole are arranged on the same straight line. One end of the fixing screw 7 passes through the through hole opened in the positioning ring 6 and is rotatably connected to the inside of the threaded hole opened in the connecting rod 8, thereby realizing the limiting effect between the positioning ring 6 and the connecting rod 8 through the fixing screw 7.

[0046] Furthermore, the bottom frame 1 and the top frame 3 each have a sliding groove on one side facing the door panel, and the limit slider 10 is inserted into the sliding groove of the bottom frame 1 and the top frame 3 and is slidably connected thereto, thereby realizing movement and limiting of the limit slider 10 through the sliding groove of the bottom frame 1 and the top frame 3.

[0047] like Figure 5As shown, movable grooves are set at the positions corresponding to the supporting piles 2 at both ends of the top frame 3 in the length direction, and an adjusting screw 11 is inserted into the vertical wall on one side of the grooved part of the movable groove along the thickness direction of the door panel 4. A supporting spring 12 is connected to the inside of one end of the adjusting screw 11, and a limiting rod 13 is connected to the outer wall of the bottom end of the limiting rod 13. The rubber pad 14 is fixed to the vertical wall on the other side of the grooved part of the top frame 3, thereby realizing the assembly between the supporting pile 2 and the top frame 3 through the limiting rod 13, and the height of the top frame 3 and the bottom can be adjusted by adjusting the installation height of the limiting rod 13, so as to realize the installation of door panels 4 of different heights.

[0048] The top of the support pile 2 is inserted into the movable groove opened on the side of the top frame 3. The support pile 2 is an L-shaped composite plate. The top plane of the L-shaped composite plate of the support pile 2 is parallel to the bottom of the movable groove opened on the top frame 3. The vertical pile plate of the side of the L-shaped composite plate extends vertically downward adjacent to the vertical surface of one side of the movable groove. A plurality of groups of spaced limiting thread grooves are opened on the vertical surface of the vertical surface facing away from the movable groove. Rubber pads 14 are set on the surface at the entrance of each limiting thread groove to achieve a buffering effect between the support pile 2 and the adjusting screw 11 through the rubber pads 14. Different settings of the limiting thread grooves can achieve different support heights of the support pile 2 on the top frame 3 and the bottom frame 4.

[0049] Furthermore, a threaded groove is opened on one side of the vertical inner wall of the movable groove of the top frame 3, and the adjusting screw 11 is rotatably connected to the inside of the threaded groove opened in the top frame 3. A groove is opened on the surface of one end of the adjusting screw 11, and one end of the support spring 12 is connected to one side of the inner wall of the groove opened by the adjusting screw 11, so that one end of the support spring 12 is limited by the groove opened by the adjusting screw 11, so that the support spring 12 supports one end of the limiting rod 13 to be inserted into the limiting groove opened by the support pile 2.

[0050] Working principle: When the sliding emergency evacuation automatic door is prevented from falling off, the positioning ring 6 is sleeved on the outer wall of one side of the connecting rod 8 to position the fixed plate 5 and the connecting rod 8, and then one end of the fixing screw 7 is passed through the through hole opened in the positioning ring 6 and rotated to be connected to the inside of the threaded hole opened in the connecting rod 8, so as to connect and fix the door panel 4 and the connecting rod 8, and the limit slider 10 is used to limit the movement of the door panel 4, and when the door panel 4 needs to be rotated, the bearing 9 is used to ensure that the door panel 4 drives the connecting rod 8 to rotate without affecting the limit slider 10, and the shape of the limit slider 10 reduces friction to avoid rotation difficulties, thereby preventing the door panel 4 from falling off and making the switch smoother.

[0051] When adjusting the anti-slip sliding emergency evacuation automatic door, the top of the supporting pile 2 is inserted into the movable groove opened in the top frame 3, and then the adjusting screw 11 is rotated to make it move inside the threaded groove opened in the top frame 3, so that the support spring 12 supports one end of the limiting rod 13 to be inserted into the limiting groove opened in the supporting pile 2, and the rubber pad 14 is used to auxiliary support the bottom end of the limiting rod 13, and the rubber pad 14 is used to buffer the space between the adjusting screw 11 and the supporting pile 2, thereby protecting both of them and limiting the space between the top frame 3 and the supporting pile 2. At the same time, door panels 4 of different heights can be installed by adjusting the spacing.

[0052] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
