To solve these problems, a new type of building sling is proposed, which improves the efficiency and safety of lifting through its innovative design. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a building sling to facilitate the lifting of items during the building process.

[0006] The brackets are U-shaped, the brackets are arranged vertically and horizontally, there are two brackets, the upper and lower parts of the two brackets are respectively fixedly connected by connecting plates, the connecting plates are L-shaped, the middle parts of the two brackets are respectively rotatably connected to both ends of a transverse shaft, both ends of the transverse shaft are respectively fixedly connected to one ends of swing arms, the swing arms are L-shaped, and one ends of the two swing arms are respectively connected to a driving assembly;

[0007] The other ends of the swing arms are respectively connected to a first limiting component, the lower ends of the brackets are connected to a second limiting component, and the first limiting component and the second limiting component cooperate with each other.

[0008] As a further limitation of this technical solution, the first limiting component includes a top plate, symmetric triangular connecting blocks are fixedly arranged on one side of the top plate, one side of each triangular connecting block is respectively attached to the other side of the corresponding swing arm end, bolts pass through the triangular connecting blocks and the other ends of the swing arms, and the bolts are threadedly connected to nuts. A group of evenly arranged clamping blocks are fixedly arranged on the other side of the top plate, and the clamping blocks are triangular plate-shaped.

[0009] As a further limitation of this technical solution, the second limiting component includes a fixed shaft, both ends of the fixed shaft are respectively fixedly arranged at the lower side ends of the brackets, a plurality of evenly arranged annular clamping grooves are arranged on the circumferential wall surface of the fixed shaft, the annular clamping grooves correspond to the clamping blocks one by one, and the clamping blocks can be clamped into the annular clamping grooves.

[0010] As a further limitation of the present technical solution, the driving assembly includes a connecting belt, the connecting belt is a flexible structure, the connecting belt bypasses a support shaft, both ends of the support shaft are respectively fixedly connected to both ends of a swing rod, the other end of each swing arm is respectively fixedly connected to one end of the swing rod, the included angle between the swing rod and the swing arm is 150 - 175 degrees, one side of the connecting belt contacts the arc wall surface of an auxiliary shaft, and both ends of the auxiliary shaft are respectively rotatably connected to the outer ends of the upper side of the bracket.

[0011] As a further limitation of the present technical solution, both ends of the connecting belt are fixedly connected to the movable end of a lifting mechanism.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are:

[0013] Through the design of symmetrical U-shaped brackets and L-shaped connecting plates, the overall stability of the lifting tool is enhanced. When the object is lifted by the connecting belt, under the action of gravity, the buckle can be snapped into the annular card slot. The heavier the object to be lifted, the deeper the buckle snaps into the annular card slot.

[0015] When the connecting belt is connected to the movable end of the lifting mechanism, the connecting belt drives the swing rod and the swing arm to swing. Due to the shearing force and the swinging action of the swing arm, the swing arm drives the top plate to move, and the block on the top plate snaps into the annular card slot. When the object to be lifted is heavier, the greater the gravity, the greater the tension on the connecting belt, and the deeper the block snaps into the annular card slot, making the connection more secure.

[0016] The connecting belt can be selected as high-elastic Oxford cloth or nylon rope according to needs to adapt to different usage environments and load-bearing requirements. BRIEF DESCRIPTION OF THE DRAWINGS
