[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model;
[0026] Referring to Figures 1-7 , the portable elevator water baffle comprises a water baffle 1, the bottom surface of the water baffle 1 is provided with a sealing strip 2, and the side surface of the water baffle 1 is fixedly provided with a gear telescopic module; the gear telescopic module is in extrusion contact with the door frame of the elevator door when working.
[0027] The gear telescopic module comprises a gear box 3 fixed to the side surface of the water baffle 1, a gear 9 rotatably installed in the gear box 3, a crank 6 installed at one end of a rotating shaft extending to the outside of the gear box 3, and a rack 8 meshing and driving the upper and lower sides of the gear 9, respectively; the two racks 8 are slidingly arranged in the gear box 3, and one support arm 4 is fixed to the end of each rack 8 away from the other, and the ends of the two support arms 4 away from each other extend to the outside of the gear box 3.
[0028] The top surface of the rack 8 on the upper side of the gear 9 is fixedly provided with a limit spring 11, and the top surface of the gear box 3 is provided with a plurality of positioning holes 10 at equal intervals, and the positioning holes 10 are matched with the upper end of the limit spring 11.
[0029] The material of the water baffle 1 in the embodiment is PVC, which has a certain flexibility; the height of the water baffle 1 is designed to be 24 cm, and the thickness of the water baffle 1 is determined according to actual needs; wherein the length of the water baffle 1 is determined by investigating the social surface in the early stage, and it is found that the width between the door frame of the current resident building and the shopping mall elevator is about 1.1-1.2 m, so the length of the water baffle 1 in the embodiment is designed to be 1.2 m, so as to meet most use scenarios; for the case that the width of the elevator door frame is between 1.1-1.2 m, the water baffle 1 can be installed and used by being appropriately bent. In other embodiments, the length of the water baffle 1 can be designed to be 1.1 m, 1.13 m, 1.15 m, etc.
[0030] Furthermore, a groove 7 is provided in the middle of each of the two support arms 4, and two guide rods 5 are fixed on the side of the baffle plate 1. The two guide rods 5 correspond to the grooves 7 on the same side, and the guide rods 5 and the grooves 7 slide relative to each other.
[0031] Furthermore, the guide rod 5 has a T-shaped structure, including a rod body fixed to the side of the baffle plate 1, and the rod body slidingly matching the slide groove 7. A limiting disc is fixed to the end of the rod body away from the baffle plate 1, and the diameter of the limiting disc is larger than the width of the slide groove 7. The design of the guide rod 5 and the slide groove 7 can increase the stability of the support arm 4 in sliding relative to the baffle plate 1 and the gearbox 3, and at the same time, it can ensure the support force when supporting the door frame of the elevator door, thereby increasing the overall strength of this application during use.
[0032] Furthermore, the limiting spring 11 is inclinedly disposed inside the gearbox 3. The lower end of the limiting spring 11 is fixed to the top surface of the rack 8 located on the upper side of the gear 9, and a positioning ball is fixed to the upper end of the limiting spring 11, which matches the positioning hole 10. The limiting spring 11 is made of an elastic metal material, such as a thin sheet of stainless steel. The material and structural characteristics make the limiting spring 11 elastic. When the gear 9 and rack 8 are meshed and driven by the crank 6, the limiting spring 11 can be moved to different positions between the positioning holes 10 along the moving direction of the upper rack 8. When the crank 6 is stopped, the limiting spring 11 and the positioning hole 10 cooperate to lock the rack 8 and the support arm 4, thereby preventing the rack 8 and the support arm 4 from accidentally springing back. When it is necessary to remove the baffle plate 1 from the door frame of the elevator door, simply press the limiting spring 11 to make its positioning ball leave the positioning hole 10, thereby canceling the limiting force of the limiting spring 11 on the rack 8 and the support arm 4. This allows the rack 8 and the support arm 4 to be locked and retracted into the gearbox 3, thus canceling the force on the door frame. At this time, the baffle plate 1 can be removed and removed.
[0033] Furthermore, rubber blocks are installed at the ends of the two support arms 4 that are far apart from each other. The use of rubber blocks can increase the tightness and stability of the contact between the support arms 4 and the elevator door frame, ensuring that the water baffle 1 can be stably installed inside the elevator door frame when the gear telescopic module drives the support arms 4, thereby effectively blocking water.
