Description

Technical Field

[0001] This utility model relates to the technical field of strap tension testing devices, and in particular to a strap load-bearing tension testing device. Background Technology

[0002] Bundles, also known as cargo straps, are used to secure goods during transportation, movement, loading, or warehousing. They are locking, will not come loose, are safe and reliable, lightweight, easy to operate, and protect objects from damage. During the production process, bundles need to undergo tensile testing to ensure their load-bearing capacity, thus guaranteeing the quality of subsequent products.

[0003] Currently, existing tensile testing devices lack a quick-fixing connection mechanism for both ends of the binding strap during actual use. This means that before conducting tensile tests, staff need to connect the ends of the binding strap to the pulling end of the tensile testing device by repeatedly wrapping and knotting the strap. However, the wrapping and knotting connection method is too cumbersome and the connection stability is poor. Utility Model Content

[0004] This utility model discloses a load-bearing tensile testing device for binding straps, which aims to solve the technical problem of inconvenience in connecting binding straps in existing binding strap tensile testing devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A strap load-bearing tensile testing device includes a frame, a hydraulic press body is embedded at the right end of the frame, the telescopic end of the hydraulic press body extends into the interior of the frame and a movable block is fixedly installed thereon, a fixed block corresponding to the movable block is provided inside the left side of the frame, a strap connection mechanism is provided between the movable block and the fixed block, and a tensile testing mechanism is provided between the fixed block and the frame.

[0007] The strap connection mechanism includes two mounting plates that are fixedly installed on the front and back of the moving block and the fixed block, respectively. Two symmetrical resistance rods are fixedly installed between the two mounting plates. The upper surfaces of the moving block and the fixed block are provided with locking grooves. The inside of the locking grooves is rotatably connected to a pressure plate through a rotating shaft. The lower surface of the pressure plate is provided with limit teeth.

[0008] In a preferred embodiment, the tensile testing mechanism includes a T-shaped cavity formed on the inner wall of the left side of the frame, a T-shaped transmission rod disposed inside the T-shaped cavity, the right end of the T-shaped transmission rod being fixedly connected to the left side of the fixing block, a pressure sensor being embedded in the inner wall of the T-shaped cavity, and the surface of one end of the T-shaped transmission rod located inside the T-shaped cavity overlapping the detection end of the pressure sensor.

[0009] In a preferred embodiment, the inner wall of the locking groove is provided with a limiting groove corresponding to the position of the pressure plate, a limiting plate is provided inside the limiting groove, and a spring is fixedly installed on the inner wall of the limiting groove. The end of the spring away from the inner wall of the limiting groove is fixedly connected to the surface of the limiting plate.

[0010] In a preferred embodiment, the limiting plate is provided with guide sliders on both the front and back sides, and the inner front wall and inner rear wall of the limiting groove are provided with guide grooves for the guide sliders to slide. The limiting plate slides in a directional manner inside the limiting groove through the guide sliders and guide grooves.

[0011] In a preferred embodiment, both the lower surface of the pressure plate and the upper surface of the limiting abutment are provided with chamfers.

[0012] By setting the chamfer, the resistance when the pressure plate contacts the limiting plate can be reduced.

[0013] In a preferred embodiment, two symmetrical mounting slide frames are fixedly installed on the upper surface of the frame, and protective baffles are slidably connected inside the two mounting slide frames via slide rails.

[0014] The protective baffle can provide protection during tensile testing.

[0015] In a preferred embodiment, the protective baffle is made of transparent PC plastic material, and a handle is fixedly installed on the upper surface of the protective baffle.

[0016] In a preferred embodiment, both the moving block and the fixed block have mounting slots extending through the limiting groove on their upper surfaces, and a push plate is fixedly connected to the upper surface of the limiting abutment through the mounting slots.

[0017] As can be seen from the above, the binding strap load-bearing tensile testing device provided by this utility model has the following technical effects.

[0018] Firstly, the end of the binding strap body is passed through the two resistance rods and placed in the locking groove. Then, the pressure plate is rotated to drive the limiting teeth to abut against the surface of the binding strap body. Under the action of the spring, the limiting plate is pushed out of the limiting groove. The end of the limiting plate that extends out of the limiting groove overlaps the top of the pressure plate, restricting the pressure plate. This completes the connection of the binding strap body. The installation is simple, and the tension of the binding strap body increases the fixing strength of the pressure plate and the limiting teeth to the end of the binding strap body, resulting in strong stability.

[0019] Secondly, the pulling force drives the fixing block and T-shaped transmission rod to apply pressure to the pressure sensor. Under the action of the pressure sensor, the pulling force generated during the pulling test is detected to achieve the effect of detecting the load-bearing capacity of the strap. The protective baffle can play a protective role during the pulling test, avoiding the sudden breakage of the strap and causing injury to external equipment and personnel, thus further improving the practicality of the device.

[0031] Reference Figures 1-5 A strap load-bearing tensile testing device includes a frame 1, a hydraulic press body 2 embedded at the right end of the frame 1, a telescopic end of the hydraulic press body 2 extending into the interior of the frame 1 and a movable block 3 fixedly installed thereon, a fixed block 4 corresponding to the movable block 3 being provided inside the left side of the frame 1, a strap connection mechanism being provided between the movable block 3 and the fixed block 4, and a tensile testing mechanism being provided between the fixed block 4 and the frame 1.

[0032] The strap connection mechanism includes two mounting plates 5 that are fixedly installed on the front and back of the movable block 3 and the fixed block 4 respectively. Two symmetrical resistance rods 6 are fixedly installed between the two mounting plates 5. The upper surfaces of the movable block 3 and the fixed block 4 are provided with locking grooves. The inside of the locking grooves is rotatably connected to a pressure plate 7 through a rotating shaft. The lower surface of the pressure plate 7 is provided with limit teeth 8.

[0033] The inner wall of the locking groove is provided with a limiting groove corresponding to the position of the pressure plate 7. A limiting plate 9 is provided inside the limiting groove. A spring 10 is fixedly installed on the inner wall of the limiting groove. The end of the spring 10 away from the inner wall of the limiting groove is fixedly connected to the surface of the limiting plate 9. The upper surfaces of the moving block 3 and the fixed block 4 are provided with an installation slot that extends into the limiting groove. A push plate 11 is fixedly connected to the upper surface of the limiting plate 9 through the installation slot.

[0034] The tensile testing mechanism includes a T-shaped cavity on the inner left side of the frame 1. A T-shaped transmission rod 12 is installed inside the T-shaped cavity. The right end of the T-shaped transmission rod 12 is fixedly connected to the left side of the fixing block 4. A pressure sensor 13 is embedded in the inner wall of the T-shaped cavity. The surface of one end of the T-shaped transmission rod 12 inside the T-shaped cavity overlaps with the detection end of the pressure sensor 13. Both the hydraulic press body 2 and the pressure sensor 13 are electrically connected to the external test management system.

[0035] The front and back of the limiting plate 9 are provided with guide sliders 14, and the inner front wall and inner rear wall of the limiting groove are provided with guide grooves for the guide sliders 14 to slide. The limiting plate 9 slides in a directional manner inside the limiting groove through the guide sliders 14 and the guide grooves.

[0036] Both the lower surface of the pressure plate 7 and the upper surface of the limiting plate 9 are provided with chamfers 15. By setting the chamfers 15, the resistance when the pressure plate 7 and the limiting plate 9 come into contact can be reduced.

[0037] Reference Figure 1 and Figure 2 In a preferred embodiment, two symmetrical mounting slide frames 16 are fixedly installed on the upper surface of the frame 1. The interior of the two mounting slide frames 16 is slidably connected to a protective baffle 17 via a slide rail. The protective baffle 17 is made of transparent PC plastic material, and a handle is fixedly installed on the upper surface of the protective baffle 17. The protective baffle 17 can provide protection during tensile testing.

[0038] Working principle: When a tensile test is required to connect the binding strap body 18, the end of the binding strap body 18 is passed through the two resistance rods 6 and placed in the locking groove. Then, the pressure plate 7 is rotated, causing the limiting teeth 8 to abut against the surface of the binding strap body 18. At the same time, under the action of the spring 10, the limiting abutment 9 is pushed out of the limiting groove. The end of the limiting abutment 9 extending out of the limiting groove overlaps the pressure plate 7, restricting the pressure plate 7. This completes the connection of the binding strap body 18. The installation is simple, and as the binding strap body 18 is pulled, the fixing strength of the pressure plate 7 and the limiting teeth 8 to the end of the binding strap body 18 increases. During the tensile test, the protective... The baffle 17 moves above the frame 1 via two mounting slide frames 16 until the frame 1 is closed. At this time, the operation of the hydraulic press body 2 drives the moving block 3 to move to the right, and performs a tension test on the binding strap body 18 fixed between the moving block 3 and the fixed block 4. During this period, the tension force drives the fixed block 4 and the T-shaped transmission rod 12 to apply pressure to the pressure sensor 13. Under the action of the pressure sensor 13, the tension generated during the tension test is detected to achieve the effect of detecting the load-bearing capacity of the binding strap. The protective baffle 17 can play a protective role during the tension test, avoiding the sudden breakage of the binding strap and causing injury to external equipment and personnel.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions.
