Description

Technical Field

[0001] The utility model relates to the technical field of window guard rails, in particular to a preassembled window guard rail with adjustable length. Background Art

[0002] Prefabricated window guardrails refer to the guardrail components that are pre-processed and assembled in the factory and then transported to the construction site for quick installation. The window guardrails mainly play a role of safety protection, preventing people from accidentally falling from high places such as windows or balconies, especially in families with children or the elderly. At the same time, the window guardrails can also play a certain decorative role, improving the overall aesthetics of the building.

[0003] Publication number CN 2221346755 U discloses a pre-assembled window guard rail with adjustable length. Compared with the traditional window guard method, the rail can be customized more flexibly and is convenient for secondary disassembly and utilization. It can not only meet the different installation requirements of users, but also complete most of the assembly work in advance to reduce the difficulty of on-site installation.

[0004] The pre-assembled window guardrail with adjustable length can limit the window guardrail by means of a provided latch. When the window guardrail needs to be disassembled, a worker is required to pull the upper and lower control heads at the same time to disengage the latch from the inside of the window guardrail so that the window guardrail can be disassembled. However, the upper and lower dimensions of the window guardrail are relatively high, so one worker is required to pull the two control heads at the same time while another worker disassembles the window guardrail. It is rather troublesome for two workers to cooperate in the assembly, and thus needs to be improved. Utility Model Content

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] The present utility model provides the following technical solutions:

[0026] Embodiment 1

[0027] Please refer to Figures 1 - 4 , the present utility model provides a technical solution: a prefabricated window guardrail with adjustable length, including a support rod 1, a first window guardrail body 2 is fixedly connected to the top of the support rod 1, a clamping mechanism 4 is arranged at the inner top of the first window guardrail body 2, a disassembly mechanism 3 is arranged at the bottom of the clamping mechanism 4, and a second window guardrail body 5 is arranged on the right side of the first window guardrail body 2;

[0028] The disassembly mechanism 3 includes a connecting plate 31, the connecting plate 31 is arranged at the bottom of the clamping mechanism 4, a bidirectional threaded rod 34 is rotatably connected to the inner side of the connecting plate 31, a rotating disc 36 is rotatably connected to the front of the bidirectional threaded rod 34, a threaded plate 32 is threadedly connected to the periphery of the bidirectional threaded rod 34, a push plate 35 is fixedly connected to the top of the threaded plate 32, a limiting rod 33 is slidably connected to the inside of the threaded plate 32, and the limiting rod 33 is fixedly connected to the inner side of the connecting plate 31.

[0029] Furthermore, a circular hole corresponding to the position of the bidirectional threaded rod 34 is opened on the inner side of the connecting plate 31, and the bidirectional threaded rod 34 is rotatably connected inside the circular hole. Through the opened circular hole, when the rotating disc 36 is rotated by an external force, the bidirectional threaded rod 34 can be driven to rotate.

[0030] Further, there are two threaded plates 32, which are respectively threadedly connected to the periphery of the bidirectional threaded rod 34. The tops of the two threaded plates 32 are respectively fixedly connected with push plates 35. When the bidirectional threaded rod 34 rotates, the push plates 35 can be driven to move through the threaded plates 32, so that the push plates 35 can push the sliding plates 46, and the positions of the sliding plates 46 can be adjusted.

[0031] Embodiment 2

[0032] Please refer to Figures 1 - 4 , and on the basis of Embodiment 1, a clamping mechanism 4 is further obtained. The clamping mechanism 4 includes a fixing plate 43, the fixing plate 43 is fixedly connected to the bottom of the second window guardrail body 5, the fixing plate 43 is fixedly connected to the top of the connecting plate 31, a connecting rod 45 is fixedly connected inside the fixing plate 43, a spring 44 is sleeved on the periphery of the connecting rod 45, a sliding plate 46 is slidably connected to the periphery of the connecting rod 45, a limiting block 41 is fixedly connected to the left side of the sliding plate 46, the limiting block 41 is slidably connected to the periphery of a hollow plate 42, and the hollow plate 42 is fixedly connected to the bottom of the first window guardrail body 2.

[0033] Further, the outer side of the spring 44 is fixedly connected to the inner and outer sides of the hollow plate 42, and the inner side of the spring 44 is fixedly connected to the outer side of the sliding plate 46. The hollow plate 42 squeezes the limiting block 41, so that the limiting block 41 squeezes the spring 44 through the sliding plate 46, so that the two limiting blocks 41 move inward, so that the limiting block 41 can be inserted into the hollow plate 42. When the hollow plate 42 does not squeeze the limiting block 41, the spring 44 can drive the sliding plate 46 and the limiting block 41 to move, so that the limiting block 41 can return to its original position.

[0034] Further, there are two connecting rods 45, the two connecting rods 45 are respectively fixedly connected to the inner side of the fixing plate 43, and the two connecting rods 45 are respectively slidably connected to the inner side of the sliding plate 46. The arranged connecting rods 45 can play a role in limiting the sliding plate 46, so that the sliding plate 46 is more stable during the moving process.

[0035] Further, a rectangular groove corresponding to the size of the sliding plate 46 is opened inside the hollow plate 42, and the sliding plate 46 is slidably connected to the inside of the rectangular groove. Through the opened rectangular groove, the limiting block 41 can be inserted into the hollow plate 42, so that the hollow plate 42 can limit the limiting block 41.

[0036] During the actual operation process, when this device is in use and it is necessary to install the second window guardrail body 5 to the right side of the first window guardrail body 2, the rotating disk 36 drives the bidirectional threaded rod 34 to rotate, causing the threaded plate 32 and the connecting plate 31 to fit together. The limiting block 41 at the bottom of the second window guardrail body 5 is inserted into the hollow plate 42. The hollow plate 42 squeezes the limiting block 41, causing the limiting block 41 to squeeze the spring 44 through the sliding plate 46, making the two limiting blocks 41 move inward so that the limiting block 41 can be inserted into the hollow plate 42. When the hollow plate 42 no longer squeezes the limiting block 41, the spring 44 can drive the sliding plate 46 and the limiting block 41 to move, enabling the limiting block 41 to return to its original position and allowing the hollow plate 42 to limit the limiting block 41, facilitating the installation of the second window guardrail body 5 to the right side of the first window guardrail body 2 by the staff.

[0037] When it is necessary to move the second window guardrail body 5 away from the first window guardrail body 2, the rotating disk 36 drives the bidirectional threaded rod 34 to rotate, causing the bidirectional threaded rod 34 to drive the push plate 35 to move through the threaded plate 32, enabling the push plate 35 to squeeze the sliding plate 46, making the sliding plate 46 drive the limiting block 41 to move, causing the two limiting blocks 41 to move inward, allowing the second window guardrail body 5 to move away from the first window guardrail body 2 and facilitating the disassembly of the second window guardrail body 5 by the staff.
