Technical Field

[0001] The utility model relates to the technical field of lifting belts, in particular to a highly adaptable annular lifting belt which is convenient for adjusting the length. Background Art

[0002] During storage and transportation, lifting belts are often used to move goods, such as machinery, equipment, steel and other bulk items. They can withstand heavy weights and reduce the labor intensity of manual handling.

[0003] Lifting operations involve a wide variety of cargo types, sizes, and weights. Therefore, the length of the lifting strap must be adjustable to suit the specific cargo to ensure a safe and stable lifting process. Adjusting the length of the lifting strap allows it to better adapt to the size and shape of the cargo. However, some length adjustment mechanisms can be complex to operate or require tools, impacting work efficiency and wasting time.

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.

[0024] The utility model provides Figure 1-6 The highly adaptable, loop-shaped sling with easy length adjustment shown in the figure comprises an outer adjustment frame 2 located outside the sling 101 and the sling 2 102, and inner adjustment frames 4 located on both sides of the sling 101. Locking assemblies 3 capable of driving the inner adjustment frame 4 to slide toward one side of the outer adjustment frame 2 are provided on both sides of the outer adjustment frame 2. Adjustment plates 405 for engaging the locking assemblies 3 are provided on both sides of the inner adjustment frame 4. Sliding clamping columns 402 capable of synchronously sliding inward or outward are provided inside the inner adjustment frame 4. The sliding clamping columns 402 are capable of clamping the sling 101.

[0025] When the inner adjustment frame 4 slides toward the side of the outer adjustment frame 2, the sliding clamping column 402 clamps the sling 101. When the inner adjustment frame 4 slides toward the side of the outer adjustment frame 2, the extension block 403 slides downward along the inclined guide groove 201, and the sliding clamping column 402 slides inward synchronously along the horizontal guide groove 404. In the process of clamping the sling 101 and the sling 2 102, the sliding clamping columns 402 on both sides clamp the sling 101 through the fixed connecting shaft 407. While completing the length adjustment, the position of the adjustment device can be locked to make it more firm, thereby ensuring the locking effect of the length adjustment device of the sling belt and avoiding displacement errors during the lifting process.

[0026] The inner adjustment frame 4 includes side panels 401 located on either side of the sling 101 and fixed connecting shafts 407 located in the middle of the side panels 401. The fixed connecting shafts 407 are located on the inner side of the sling 101. Two horizontal guide grooves 404 are defined on the end surfaces of the side panels 401. The sliding clamping columns 402 are slidably disposed within the horizontal guide grooves 404. The sliding clamping columns 402 are located on the outer side of the sling 101. The end surfaces of the sliding clamping columns 402 can be configured as flat surfaces to increase friction, or can be provided with friction-enhancing patterns to prevent slipping.

[0027] The outer adjustment frame 2 is provided with inclined guide slots 201 on either side. Extension blocks 403 are provided at both ends of the sliding clamping column 402. These extension blocks 403 extend into the inclined guide slots 201 and form a sliding connection. The combination of the inclined guide slots 201 and the longitudinal slide slots 202 controls the sliding direction of the inner adjustment frame 4, preventing it from tilting during adjustment and ensuring a secure lock after length adjustment.

[0028] The outer adjustment frame 2 is also provided with rotating connection blocks 203 on both sides. Mounting holes 204 are defined within these rotating connection blocks 203 for the locking assembly 3 to rotate. The locking assembly 3 includes a rotating connection shaft 301 that can rotate about the mounting holes 204. A threaded rod 302 is provided on the outer sidewall of the rotating connection shaft 301. The rotating connection blocks 203 can also be positioned within the outer adjustment frame 2 to prevent the rotating connection blocks 203 from breaking or separating from the outer adjustment frame 2, which could cause the outer adjustment frame 2 to fail.

[0029] The outer side of the threaded rod 302 is threadedly connected to a wing nut 303 for clamping and fixing. The adjustment plate 405 defines a slot 406 for receiving the threaded rod 302. When the threaded rod 302 is rotated to a vertical position, the threaded rod 302 is located within the slot 406, and the wing nut 303 is located at the top of the adjustment plate 405. The wing nut 303 is located at the top of the adjustment plate 405. By pressing the inner adjustment frame 4, the wing nut 303 can be quickly rotated, thereby fixing the inner adjustment frame 4 in a specified position and improving the locking effect.

[0030] The outer adjustment frame 2 is further provided with a longitudinal slot 202 for the adjustment plate 405 to slide in the vertical direction, and the adjustment plate 405 extends to the outside of the outer adjustment frame 2. The adjustment plate 405 is arranged on the outside of the outer adjustment frame 2 to facilitate the rotation of the butterfly nut 303 and reduce the difficulty of operation.

[0031] The utility model is a highly adaptable annular sling with easy length adjustment. When the length of the sling needs to be adjusted, the butterfly nut 303 is loosened and the threaded rod 302 is rotated to separate the threaded rod 302 from the adjusting plate 405, so that the inner adjustment frame 4 can slide outward quickly, driving the sliding clamping column 402 to slide outward, loosening the sling 101, and achieving the purpose of quick loosening, thereby improving the speed of quickly adjusting the sling length. If slow loosening is required, the butterfly nut 303 is controlled to rotate around the nut rod to make it slide outward slowly, thereby reducing the loosening speed, which is convenient for use in the process of precise lifting. By controlling the rotation speed of loosening the butterfly nut 303 or controlling the rotation of the threaded rod 302, it can be applied to various lifting environments and provide product adaptability. After the length adjustment is completed, After completion, by controlling the rotation of the butterfly nut 303, the extension block 403 slides downward along the inclined guide groove 201, driving the inner adjustment frame 4 to slide toward the side of the outer adjustment frame 2, which can drive the sling 101 and the sling 2 102 to squeeze and clamp each other, reducing the shaking of the sling during the lifting process, and improving the stability of clamping and fixation, thereby avoiding the relative displacement of the two directions during the lifting process, affecting the lifting effect. At the same time, the extension block 403 drives the sliding clamping columns 402 on both sides to slide inward synchronously, clamping the sling 101, ensuring that the sling will not fall off or slide due to external force, so as to prevent accidents with the sling during the lifting process. The butterfly nut 303 and the threaded rod 302 can be manually rotated, which is convenient for quickly adjusting the length of the sling under low load conditions, thereby improving the working speed.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
