In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0027] The factory fire evacuation indication system disclosed by the utility model is described below in conjunction with the accompanying drawings. Figure 1 , Attachment Figure 2 As shown, it includes a group of evacuation indicator lights 200 arranged under the roof 110 of the factory building 100, a track 300 is arranged under the roof 110 of the factory building 100, a group of sliding blocks 400 are slidably arranged on the track 300, each of the sliding blocks 400 is rotatably provided with a rotating shaft 500 extending in a vertical direction, and the lower end of the rotating shaft 500 is connected to the evacuation indicator light 200.
[0028] When the production line structure in the factory 100 changes, the position of the evacuation indicator light 200 on the track 300 can be adjusted and the direction of the evacuation indicator light 200 can be rotated to quickly adapt to the indication needs of the new fire evacuation passage after the production line layout changes. There is no need to disassemble and install the evacuation indicator light 200, which greatly improves the flexibility and adaptability of the layout.
[0029] As attached Figure 1 , Attachment Figure 3As shown, the track 300 is distributed in a grid shape and includes mutually perpendicular and intersecting transverse tracks 310 and vertical tracks 320. The number of the transverse tracks 310 and vertical tracks 320 can be designed according to needs. For example, the transverse tracks 310 and vertical tracks 320 can be distributed in a cross shape, a field shape, or a well shape, etc., which is not limited here.
[0030] At the same time, in order to facilitate the movement of the sliding block 400 between different tracks 300, the horizontal track 310 and the vertical track 320 are connected slide grooves 330, and the horizontal track 310 and the vertical track 320 can be assembled from multiple slide grooves 330, or can be an integral track 300, and the sliding block 400 can be slidably arranged in the slide groove 330, and the bottom of the slide groove 330 has an avoidance hole 331 for the movement of the rotating shaft 500. In addition, in order to facilitate the fixing of the track 300 to the roof 110, the tops of the side panels on both sides of the horizontal track and the vertical track 320 have a connecting portion 332 bent outward by 90 degrees, and a strip hole 334 is arranged at the connecting portion 332, and the connecting portion is fixed below the roof 110 by screws penetrated at the strip hole.
[0031] Furthermore, in order to enable the sliding block 400 to move smoothly at the intersection of the transverse rail 310 and the vertical rail 320, the top corner 333 of the intersection of the slide groove 330 of the transverse rail 310 and the vertical rail 320 is rounded, the top corner of the intersection of the avoidance hole 331 is rounded, and the four side top corners 410 of the sliding block 400 are rounded.
[0032] As attached Figure 2 As shown, in order to facilitate the movement of the sliding block 400 and avoid wear between the sliding block 400 and the track 300, a polytetrafluoroethylene coating 600 is provided on the bottom surface of the sliding block 400. The polytetrafluoroethylene material itself has lubricity and wear resistance, which can make the sliding block 400 slide more smoothly while reducing wear and noise.
[0033] In order to facilitate the installation of the rotating shaft 500, an installation groove is provided on the sliding block 400, and a planar thrust ball bearing 700 is provided in the installation groove on its step surface. The upper circle of the planar thrust ball bearing 700 protrudes above the top surface of the sliding block 400, and the upper end of the rotating shaft 500 has an end plate 510, and the diameter of the end plate 510 is larger than the aperture of the planar thrust ball bearing 700, so that the rotating shaft 500 passes through the upper hole of the planar thrust ball bearing 700 and its end plate 510 is limited above the upper circle.
[0034] Furthermore, in order to prevent the rotating shaft 500 from rotating randomly, the sliding block 400 is provided with a damping sleeve 800 located below the planar thrust ball bearing 700. The damping sleeve 800 is fixed on the sliding block 400. The damping sleeve 800 is sleeved on the rotating shaft 500. The damping sleeve 800 is a silicone sleeve or a rubber sleeve. The damping sleeve 800 can provide a certain friction resistance to the rotation of the rotating shaft 500, so that it cannot rotate randomly. The rotating shaft 500 can only be rotated when the operator uses sufficient thrust.
[0035] A connecting plate is disposed at the lower end of the rotating shaft 500 and can be screwed to the top of the evacuation indicator light.
[0036] The evacuation indicator light 200 can be a known evacuation indicator light 200 with a built-in battery and can communicate with the outside through a known wireless communication method. Of course, in other embodiments, a center hole extending along its axial direction can also be formed on the rotating shaft 500, and the center hole can be used for wiring, so as to facilitate the power supply of the evacuation indicator light 200. A conductive rail can be set at the inner wall of the corresponding slide 330, and the conductive rail is connected to the power supply. The slide 330 is made of insulating material, and the slider is also made of insulating material. The slider is provided with power-taking shrapnel corresponding to the conductive rails in two directions, and the power-taking shrapnel keeps in contact with the conductive rail to achieve power supply. Of course, in other embodiments, a wired method can also be adopted. In this case, the cable needs to have a sufficient length, or the moving range of each evacuation indicator light 200 can be considered.
[0037] There are many implementation methods of the utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the utility model.
