Description

Technical Field

[0001] This utility model relates to the field of cargo binding technology, and in particular to a safety binding device with protective functions. Background Technology

[0002] Bundling and securing devices are a particularly important tool for securing goods in transportation. Bundling and securing devices, also known as cargo straps, are used to secure goods during transportation, moving freight, or other processes. They are characterized by their locking mechanism, preventing them from falling off, ensuring safety and reliability, being lightweight, easy to operate, and protecting objects from damage. Depending on the type of hook, they are suitable for various environments and are also known as binding devices, fasteners, securing straps, and military binding straps.

[0003] However, existing binding devices still have the following problems during use:

[0004] 1. In existing safety binding devices, the gears of the retractable webbing are generally assembled inside the product. During retraction, due to incorrect assembly methods, the gears often get stuck, which causes the retractable webbing to be unsmooth.

[0005] 2. As a spring used for retraction, its outer cover is fixed by riveting with pins at both ends. This fixing structure is not strong and is costly.

[0006] 3. The outer body of the product is used to assemble various small parts. Many products on the market have an outer body that is a single piece on both the left and right sides. When assembling various parts such as pins, the holes cannot be aligned because the left and right sides are bent, which makes assembly difficult and time-consuming.

[0007] 4. When the webbing retracts, many products on the market cannot retract at a uniform speed. Because the webbing retracts too quickly, it may hit the consumer's hand, creating a safety hazard.

[0008] 5. In existing safety harness products, the spring ends on the handle parts are exposed on the front of the product. When the user pulls the handle, the exposed spring ends can injure the user's hand, creating a safety hazard.

[0009] Therefore, a safety harness device with protective functions is needed for use. Utility Model Content

[0010] To address the above problems, this utility model provides a safety binding device with protective functions, the specific technical solution of which is as follows:

[0011] A safety binding device with protective function includes a left plate and a right plate. Bolts and loosening nuts are provided at the rear ends of the left and right plates. The bolts pass through the left and right plates and the loosening nuts to fix the left and right plates. A left washer and a right washer are respectively provided between the left and right plates. Each of the left and right washers has a groove. A main shaft is provided between the left and right washeres. Each end of the main shaft has a locking block that engages with the groove. A rotating shaft passes through the main shaft, extending from the left plate to the outside of the right plate. A retaining ring is provided on the rotating shaft and engages with the right plate. A protective cover is provided on the right plate, and the protective cover contains... The device has a spring, which is mounted on a rotating shaft at its center and connected to a cover. A left handle cover and a right handle cover are respectively located at the front ends of the left and right plates, and a connecting fixing shaft is located at their rear ends. A handle is located between the left and right handle covers. A left sleeve and a right sleeve are respectively located on the left and right plates. Two shafts are located between the left and right sleeves, with a gap between them. A left gear and a right gear are respectively inserted on the left and right sides of each shaft. Fixing strips are provided at the ends of the two shafts for fixation, and a knob is located on the fixing strip at the position of the right gear.

[0012] Furthermore, the right cover has three circumferentially distributed protruding ports, and the cover is snapped into the three protruding ports.

[0013] Furthermore, a safety buckle fixing block is snapped into place at the middle position of the left and right plates. The left and right plates are respectively provided with sliding grooves, and a safety buckle with sliding fit is provided between the two sliding grooves. A safety buckle spring is provided between the safety buckle fixing block and the safety buckle.

[0014] Furthermore, a pin and a safety buckle pin are riveted between the left and right handle covers.

[0015] Furthermore, both the left and right covers of the handle are provided with sliding grooves, and the two ends of the handle are slidably connected in the two sliding grooves respectively. A handle spring is fixedly connected to the handle, and the handle spring is fixed to the right cover of the handle.

[0016] Furthermore, a protective pad is provided between the left or right gear and the fixing bar.

[0017] Beneficial effects: 1. The gears of the retractable webbing are designed to be located at both ends of the product, making assembly quick. Because they are assembled at the outer end, they are not interfered with by other internal assembly parts, so the gears do not get stuck during rotation, resulting in smooth gear rotation and thus smooth webbing retraction.

[0018] 2. The outer cover of the spring is pressed into the right plate by a protruding port, which secures the cover to the product and ensures stable retraction of the webbing;

[0019] 3. The main body consists of separate left and right panels, which allows for quick assembly and low cost. Because they are separate parts, the holes on the left and right panels are easier to align and assemble, resulting in a high assembly qualification rate.

[0020] 4. The product has a knob at the outer end of the retraction position. By turning this knob, the gear is pressed to generate frictional resistance, so that the webbing retracts at a uniform speed, thus preventing it from hitting the user's hand and ensuring safety and security.

[0021] 5. The handle spring end is a concealed structure. Because the spring end is hidden on the back of the handle, the user can avoid the sharp corner of the spring end when pulling up or down the handle, so as not to hurt the user's hand, making it safe and secure. Attached Figure Description

The two ends of the handle 14 are slidably connected to the two sliding grooves 29 respectively. A handle spring 24 is fixedly connected to the handle 14, and the handle spring 24 is fixed to the right handle cover 12. The sliding grooves 29 allow the handle 14 to slide and be limited when it moves.

[0034] Preferably, a protective pad 25 is provided between the left gear 30 or the right gear 31 and the fixing strip 18; the protective pad 25 creates a gap between the left gear 30 or the right gear 31 and the fixing strip 18.
