[0002] A cargo strap fastener is a tool used to secure and tie cargo. It usually consists of a strap and an adjustable fastening device. The strap is usually made of high-strength fiber materials such as polyester or nylon. The fastening device can be a metal buckle or button that is used to adjust the tightness of the strap. Cargo strap fasteners are very convenient to use and can adapt to a variety of cargo sizes and shapes. They are widely used in industries such as cargo transportation, logistics, and warehousing. The use of cargo strap fasteners can ensure that the cargo remains stable and secure during transportation and prevent the cargo from moving or being damaged. In the prior art, if the straps are not properly tight, the materials are damaged, or they are used improperly, the cargo may become loose during transportation. In addition, vibrations, bumps, sharp turns, etc. during transportation may also cause the straps to loosen, and loose straps will affect the stability of the cargo.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 , the utility model provides a technical solution:

[0025] A cargo strap fastener comprises a fixed base 1, on which a movable component is provided for adjusting a clamping position;

[0026] The moving component includes a T-slot 2 opened inside the fixed base 1, the inside of the T-slot 2 is rotatably connected to a first screw rod 3, one end of the first screw rod 3 passes through the fixed base 1 and is fixedly connected to a motor 4, the outer side of the first screw rod 3 is threadedly connected to a T-rod 5, the T-rod 5 is slidably connected to the T-slot 2, the upper end of the T-rod 5 is fixedly connected to a limiting frame 6, the limiting frame 6 is slidably connected to the fixed base 1, and a clamping mechanism 8 for fixing the strap is provided on the limiting frame 6.

[0027] The clamping mechanism 8 includes a fixed block 81 fixedly installed on the bottom of the limit frame 6, and two evenly distributed grooves 82 are opened inside the fixed block 81. A moving block 83 is slidably connected inside the limit frame 6. The lower end of the moving block 83 is fixedly connected with two evenly distributed clamping blocks 84, and the lower end of the moving block 83 is fixedly connected with a plurality of evenly distributed pointed blocks 85. The internal thread of the moving block 83 is connected with a second screw 86, and the second screw 86 is rotatably connected to the limit frame 6. The upper end of the second screw 86 is fixedly connected with a rotating disk 87, and the rotating disk 87 is rotatably connected to the limit frame 6. A limiting component 88 for limiting the limiting disk is commonly provided on the limit frame 6 and the rotating disk 87.

[0028] Exemplarily, the rotating disk 87 is rotated, and the rotating disk 87 drives the second screw 86 to rotate, and a threaded motion occurs between the second screw 86 and the moving block 83 to control the moving block 83 to rise or fall. When the moving block 83 falls, the block 84 and the groove 82 cooperate to fix the strap. When the moving block 83 falls, multiple pointed blocks 85 fix the strap at the same time. A pressure sensor is provided at one end of the fixed block 81, and a controller is provided at the lower end of the pressure sensor, which is electrically connected to the pressure sensor and the motor 4 respectively.

[0029] Two latches 84 are adapted to fit into the grooves 82 .

[0030] Exemplarily, the groove 82 receives the block 84 .

[0031] The fixed block 81 and the movable block 83 are both as wide as the interior of the limiting frame 6 .

[0032] Exemplarily, the moving block 83 has the same width as the interior of the limiting frame 6 , so that when the moving block 83 moves, the limiting frame 6 can limit the moving block 83 .

[0033] The limiting assembly 88 includes a plurality of limiting holes 881 distributed in an annular pattern and opened at the upper end of the limiting frame 6. The limiting holes 881 are internally slidably connected to a limiting rod 882. The outer side of the limiting rod 882 is fixedly connected to a moving ring 883. The moving ring 883 is slidably connected to the rotating disk 87. The outer side of the limiting rod 882 is sleeved with a spring 884.

[0034] Exemplarily, the limit rod 882 is pulled out, the spring 884 is compressed, the limit rod 882 moves out of the limit hole 881, and the limit on the rotating disk 87 is released. When the limit rod 882 is released, under the action of the elastic force of the spring 884, the moving ring 883 drives the limit rod 882 to move, and the limit rod 882 is stuck in the limit hole 881 to limit the rotating disk 87.

[0035] The interior of the limiting frame 6 is rotatably connected with a roller 7 , and both ends of the roller 7 are provided with a rotating shaft, which is rotatably connected to the limiting frame 6 .

[0036] Exemplarily, when the binding belt is installed into the limiting frame 6, the roller 7 plays a role of assisting entry.

[0037] Working principle: When the utility model is used, the strap is installed into the limit frame 6, the strap passes through the roller 7 and enters the limit frame 6, the limit rod 882 is pulled out, the spring 884 is compressed, the limit rod 882 moves out of the limit hole 881, and the limit on the rotating disk 87 is released. The rotating disk 87 is rotated, and the rotating disk 87 drives the second screw 86 to rotate. The second screw 86 and the moving block 83 have a threaded movement to control the moving block 83 to rise or fall. When the moving block 83 falls, the block 84 cooperates with the groove 82 to fix the strap. When the moving block 83 falls, multiple pointed blocks 85 fix the strap at the same time, avoiding the problem that the clamping block is set inside the protective shell and is inconvenient to operate. The limit rod 882 is loosened. Under the elastic force of the spring 884, the moving ring 883 drives the limit rod 882 to move, and the limit rod 882 is stuck in the limit hole 881 to limit the rotating disk 87.

[0038] A pressure sensor is provided at one end of the fixed block 81. When the strap is tightened, the strap is separated from the pressure sensor. When the strap is loosened, the strap is pressed on the pressure sensor. The pressure sensor transmits a signal to the controller. The controller controls the motor 4 to turn on. The motor 4 drives the first screw 3 to rotate. A threaded movement occurs between the first screw 3 and the T-bar 5, which controls the T-bar 5 to slide inside the T-slot 2, thereby tightening the strap for a second time.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
