Description

Technical Field

[0001] The utility model relates to the field of guardrails, in particular to a building lifting guardrail. Background Art

[0002] Guardrail is a kind of railing structure used to isolate and limit the range of movement of people, vehicles or objects to reduce certain risks. It restricts the movement of people and vehicles through stable structural form, high-strength materials and reasonable design, thereby protecting the lives of the public. Guardrail has multiple functions in different occasions, including safety protection, guidance, warning, anti-collision, decoration, environmental protection, management and control, etc.

[0003] Currently, most construction guardrails lack the function of lifting. When the guardrails need to be temporarily adjusted to allow external vehicles or personnel to enter the construction area, the guardrails lacking the lifting function may become an obstacle. Workers are also required to manually remove or reassemble the installed guardrails, which takes a lot of manpower and time and lacks flexibility. Utility Model Content

[0004] In order to make up for the deficiency of the prior art, that is, the problem that the guardrail lacks the lifting function, the utility model proposes a building lifting guardrail.

[0005] The utility model solves the technical problem by adopting the following technical solution: a building lifting guardrail, comprising two guardrails, a guard plate is arranged between the two guardrails, and a U-shaped connecting plate is fixedly connected to one side wall of the guardrail;

[0006] An unfolding assembly is arranged on the surface of the fence post, an adjusting assembly is arranged on one side of the fence post, a limited position guiding assembly is arranged between the guard plate and the fence post, and a lifting assembly is arranged inside one of the fence posts.

[0007] Preferably, the unfolding assembly comprises unfolding plates respectively rotated on both sides of the surface of the fence post, and a side block is fixedly connected to one side wall of the unfolding plate.

[0008] Preferably, the adjustment assembly comprises a U-shaped fixing plate fixed to one side wall of the railing, the inner wall of the U-shaped fixing plate being rotatably connected to a threaded rod 1, one end of the threaded rod 1 movably passes through the surface of the U-shaped fixing plate and is fixedly connected to a knob.

[0009] Preferably, a movable block is threadedly sleeved on the surface of the threaded rod 1, and both side walls of the movable block are rotatably connected to side plates, and the two side plates are respectively rotatably connected to the surfaces of two side blocks on the same side.

[0010] Preferably, the limiting guide assembly includes limiting plates respectively fixed on both sides of the guard plate surface, the tops of the two railings are provided with limiting grooves, the two limiting plates are respectively slidably connected to the inner cavities of the two limiting grooves, and a through hole is provided on the surface of one of the limiting plates.

[0011] Preferably, the lifting assembly comprises a built-in groove opened inside one of the fence posts, and a driving part is installed in the inner cavity of the built-in groove.

[0012] Preferably, the output shaft of the driving part is transmission-connected with a second threaded rod, one end of which movably penetrates the inner wall of the built-in groove, and the thread penetrates the surface of the limiting plate and is placed in the inner cavity of the through hole.

[0013] The utility model is beneficial in that:

[0014] The utility model uses a driving part arranged inside the fence post. When the guard plate at that location needs to be lifted or lowered, the driving part is controlled to rotate the threaded rod 2, so that the guard plate moves upward under the action of the limiting plate and the limiting groove, and finally a gap is formed between the two fence posts for people and vehicles to enter and exit, thereby realizing the lifting and lowering control of the guard plate, saving time and labor, and improving the flexibility and practicality of the device in actual use.

[0015] The utility model is provided with an unfolding plate, and when the device is installed, the threaded rod one is rotated to make the movable block move downward on the threaded rod one, so that the two side plates make the two U-shaped fixing plates rotate relatively and present an unfolded state, thereby increasing the contact area between the device and the ground, thereby ensuring its stability after installation. The foldable design also facilitates the transportation and storage of the device. BRIEF DESCRIPTION OF THE DRAWINGS
