Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a protective device for elevator floor doors used in building construction. Background Technology

[0002] Construction is a complex and systematic engineering activity encompassing numerous stages and tasks. It includes the construction, expansion, renovation, and demolition of various buildings and structures. From initial site leveling and earthwork excavation to the erection of the main structure, such as creating a robust framework with reinforced concrete, followed by exterior wall and roof construction, and the laying of internal plumbing, electrical, and heating lines and pipes, the construction process involves collaboration among multiple trades, such as bricklayers, carpenters, and electricians, each with their specific roles. Various mechanical equipment, such as cranes and welding machines, are used to improve efficiency. Simultaneously, strict adherence to building codes is crucial to ensure project quality, worker safety, and successful project delivery.

[0003] During construction, elevator door safety devices are needed to protect elevator doors in buildings and prevent people from falling from unclosed elevator doors and causing injury or death. However, current elevator door safety devices usually cannot adjust the width, making them unsuitable for elevator doors of different widths. Furthermore, current elevator door safety devices usually only have a protective function and are relatively simple in function.

[0004] In response to this technical problem, this application proposes a protective device for elevator floor doors in building construction. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of an elevator floor door protection device for building construction, comprising two vertical rods 8. A horizontal rod 4 is fixedly connected to the top of the left vertical rod 8, and a sliding rod 7 is fixedly connected to the top of the right vertical rod 8. The sliding rod 7 is slidably connected inside the horizontal rod 4. The two vertical rods 8 are connected by a telescopic rod 9. A fixing rod 10 is fixedly connected to the left side of the telescopic rod 9. A shelf 2 for placing items is rotatably connected to the top of the fixing rod 10 and the left vertical rod 8. (See reference...) Figure 3 The slide rod 7 has a groove at its left end, and a round tube 11 is fixedly connected inside the groove. Round rods 12 are slidably connected to both ends of the round tube 11. An insertion rod 13 is fixedly connected to the end of the round rod 12. A slot is provided inside the crossbar 4, and the insertion rod 13 is inserted into the slot. By inserting the insertion rod 13 into the slot, the slide rod 7 is fixed in the crossbar 4. A metal plate 14 is fixedly connected to the outer wall of the insertion rod 13. A spring 15 is sleeved on the outer wall of the round tube 11. The rear end of the spring 15 is connected to the front side of the rear insertion rod 13, and the front end of the spring 15 is connected to the rear side of the front insertion rod 13. The metal plate 14 disengages the insertion rod 13 from the slot, and the spring 15 holds the insertion rod 13 firmly in the slot. (Refer to...) Figure 1 Metal rods 5 are fixedly connected to both the front and rear sides of the right end of the crossbar 4. Insert plates 6 are rotatably connected to the outer wall of the metal rods 5. The outer wall of the slide rod 7 has a slot, and the insert plates 6 are engaged in the slot. The slide rod 7 is further fixed by engaging the insert plates 6 in the slot.

[0028] Reference Figure 4 - Figure 6The front sides of the fixed rod 10 and the left vertical rod 8 are slidably connected to the slide seat 17. The bottom side of the shelf 2 is fixedly connected to two rotating seats 20. The rotating seats 20 and the slide seat 17 are connected by a support rod 16. The top end of the support rod 16 is rotatably connected to the inside of the rotating seat 20, and the bottom end of the support rod 16 is rotatably connected to the inside of the slide seat 17. By sliding the slide seat 17, the support rod 16 is pushed upward and the rotating seat 20 is pushed up, which in turn pushes the shelf 2 up, so that the shelf 2 unfolds. The bottom side of the slide seat 17 is rotatably connected to two limiting rods 18. The outer walls of the fixed rod 10 and the left vertical rod 8 are fixedly connected to two limiting seats 19. The limiting rods 18 are engaged with the limiting seats 19. By rotating the limiting rods 18 and engaging them with the limiting seats 19, the slide seat 17 is fixedly fixed. The top side of the slide rod 7 is equipped with two lighting lamps 3 for lighting. The bottom end of the vertical rod 8 is fixedly connected to a base 1.

[0029] Working principle: First, move the device to the elevator floor door, then pull the insert plate 6 out of the slot, and press the metal plate 14 to disengage the insert rod 13 from the slot. Then, pull the crossbar 4 according to the width of the elevator floor door to adjust the length of the slide rod 7 protruding from the crossbar 4, so that the overall length of the device is adjusted. After adjustment, release the metal plate 14 so that the spring 15 presses the insert rod 13 into the slot, thus initially fixing the slide rod 7. Then, rotate the insert plate 6 to engage it in the slot, thus further fixing the slide rod 7. Then, the shelf 2 can be unfolded as needed to place some items. When the shelf 2 needs to be unfolded, first slide the slide block 17 to slide it upward to lift the rotating block 20, so that the rotating block 20 lifts the shelf 2, thus unfolding the shelf 2. Then, rotate the limiting rod 18 and engage it on the limiting seat 19 to fix it, thus fixing the slide block 17, and thus fixing the shelf 2. Then, items can be placed on the shelf 2.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
