Description

Technical Field

[0001] This utility model belongs to the field of logistics equipment technology, and in particular relates to an electronic sealing buckle. Background Technology

[0002] Logistics equipment refers to machinery, tools, or automated facilities used in logistics activities for storage, handling, transportation, sorting, packaging, etc., aiming to improve efficiency, reduce costs, and ensure the safety of goods. Electronic sealing buckles are a new type of logistics equipment. They are smart locks based on Internet of Things (IoT) technology, used to replace traditional physical lead seals, enabling real-time monitoring, tamper-proofing, and data tracking of transport containers. They are widely used, especially in cross-border logistics, high-value cargo transportation, and cold chain logistics.

[0003] An electronic lead seal is disclosed in a document with the existing authorization announcement number CN221899687U, which includes a main housing, a circuit board, a signal transmitting tube and a signal receiving tube fixed on the circuit board, a control motor fixed inside the main housing, and an optical cable passing through the main housing. The optical cable includes a fixed end and a detachable end fixed inside the main housing. A removable clamping component is provided inside the main housing to control the clamping and releasing of the detachable end of the optical cable. The output end of the control motor is connected to the removable clamping component.

[0004] However, it still has the following drawbacks in practical use:

[0005] The aforementioned electronic seal uses a removable clamping component to compress and release the detachable end of the optical cable inside the electronic seal, allowing it to be reused multiple times. However, during transportation, the electronic seal may shake as the transport container moves, causing a collision between the electronic seal and the transport container. This collision can damage the electronic components such as the circuit board inside the electronic seal, thus affecting its service life.

[0006] The aforementioned electronic seal uses a removable clamping component to compress and release the detachable end of the optical cable inside the electronic seal, allowing it to be reused multiple times. However, during use, since the length of the optical cable is fixed, when used on different transport containers, the cable may be too long to completely seal the transport container, potentially resulting in gaps in the transport container.

[0007] To address these issues, we provide an electronic sealing buckle. Utility Model Content

[0008] The purpose of this invention is to provide an electronic sealing buckle that uses an adsorption plate and a first permanent magnet to adsorb the outer shell onto a transport container such as a shipping container, and uses a buffer spring to reduce the impact force on the outer shell, thereby preventing damage to the electronic components inside the outer shell due to shaking. This solves the problem of existing buckles that are inconvenient to transport and cause damage to electronic components due to shaking. At the same time, the outer and inner clamping blocks fix the U-shaped rod and the mounting frame, thereby reducing the connection gap between the U-shaped rod and the transport container through the mounting frame, solving the problem of existing buckles that are inconvenient to reduce the connection gap.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0010] This utility model relates to an electronic sealing buckle, comprising a housing and a U-shaped rod.

A fixing block is fixedly connected to the center of the interior of the mounting frame, and electromagnets are fixedly connected to the centers of the outer walls on both sides of the fixing block. Outer clamping blocks are fixedly connected to both sides of the interior of the mounting frame, and inner clamping blocks are movably connected between adjacent fixing blocks and outer clamping blocks. The outer and inner clamping blocks are respectively engaged with the two sides of the vertical support arm of the U-shaped rod. A second permanent magnet is fixedly connected to the side of each inner clamping block closest to the fixing block.

[0011] A further feature of this invention is that: an equipment box is fixedly connected to the bottom inner side of the outer shell, and interfaces are electrically connected to both sides of the top of the equipment box; the bottom ends of the vertical support arms of the U-shaped rod are electrically connected to the inside of the interfaces.

[0012] A further feature of this invention is that a motor is fixedly connected to one side of the rear end face inside the housing via a mounting bracket, and a threaded rod is fixedly connected to the output shaft of the motor. The end of the threaded rod away from the motor is rotatably connected to the inner wall of one side of the housing. Slider blocks are threadedly connected to both sides of the outer wall of the threaded rod, and movable plates are fixedly connected to the front end faces of the sliders. The sides of the movable plates that are far apart from each other are snapped onto one side of the vertical support arm of the U-shaped rod.

[0013] A further feature of this invention is that multiple snap-fit ​​holes are equally spaced on one side of the vertical support arm of the U-shaped rod, and snap-fit ​​posts are fitted inside the snap-fit ​​holes with clearance. The end of the snap-fit ​​post located outside the snap-fit ​​hole is fixedly connected to the movable plate.

[0014] A further feature of this invention is that damping cylinders are fixedly connected to all four sides of the rear end face of the mounting plate, and piston shafts pass through the rear ends of the damping cylinders. A piston plate is fixedly connected to one end of the piston shaft located inside the damping cylinder, and a connecting plate is fixedly connected to one end of the piston shaft located outside the damping cylinder. The rear end face of the connecting plate is fixedly connected to all four sides of the front end face of the adsorption plate.

[0015] A further feature of this invention is that: a first ear seat is welded to the upper part of both outer walls of the outer shell, and a second ear seat is welded to both outer walls of the mounting frame. A limiting rod is fixedly connected to the bottom of each second ear seat, and the bottom end of the limiting rod passes through the first ear seat and is fixedly connected to a limiting plate.

[0016] A further feature of this invention is that: sliding rods are fixedly connected to the front and rear ends of the outer walls on both sides of the fixing block; the end of the sliding rod away from the fixing block passes through the inner clamping block and is fixedly connected to the outer clamping block; a return spring is sleeved on the outer side of the sliding rod; and the two ends of the return spring are fixedly connected to the fixing frame and the inner clamping block, respectively.

[0017] A further feature of this invention is that multiple positioning holes are equally spaced on one side of the vertical support arm of the U-shaped rod, and a positioning post is fitted inside one of the positioning holes with a gap. The end of the positioning post located outside the positioning hole is fixedly connected to the outer wall of the inner clamping block near the outer clamping block.

[0018] This utility model has the following beneficial effects:

[0019] This invention utilizes an anti-sway component, which seals the transport container with a lead seal using the outer shell and a U-shaped rod, and magnetically attaches a first permanent magnet to the transport container. This fixes the outer shell, preventing it from shaking. Furthermore, when the outer shell vibrates due to the transport container, the damping fluid in the buffer spring and damping cylinder work together to reduce the vibration, protecting the internal electronic components and preventing damage during transport caused by the outer shell shaking. This extends the product's lifespan.

[0020] This invention, by setting auxiliary components, moves the mounting frame to a specified height and connects the power supply to the electromagnet, causing the electromagnet's magnetism to be opposite to that of the second permanent magnet. Under the mutual repulsion of the electromagnet and the second permanent magnet, the inner clamping block moves towards the outer clamping block, thereby engaging the U-shaped rod with the mounting frame through the outer and inner clamping blocks. This allows for adjustment of the gap between the U-shaped rod and the transport container, preventing the transport container from failing to seal completely due to excessive gaps, facilitating sealing of the transport container, and improving safety.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The mounting frame 401 is designed to reduce the connection gap between the U-shaped rod 2 and the transport container, thereby preventing the transport container from failing to seal due to excessive gap. The fixing block 402 is designed to install the electromagnet 402c. The electromagnet 402c, together with the second permanent magnet 404a, drives the inner clamping block 404 to move. The outer clamping block 403 and the inner clamping block 404 are designed to snap the mounting frame 401 onto the U-shaped rod 2.

The two ends of the return spring 402b are fixedly connected to the fixed frame and the inner clamping block 404 respectively.

[0047] Multiple positioning holes 202 are equally spaced on one side of the vertical support arm of the U-shaped rod 2.

[0048] The rest of the structure is the same as in Example 1.

[0049] The operation process of this embodiment is as follows: the mounting frame 401 is moved to a specified height, and the power supply of the electromagnet 402c is turned on, so that the magnetism of the electromagnet 402c is opposite to that of the second permanent magnet 404a. At this time, under the mutual repulsion of the electromagnet 402c and the second permanent magnet 404a, the inner clamping block 404 moves towards the outer clamping block 403, thereby engaging the U-shaped rod 2 with the mounting frame 401 through the outer clamping block 403 and the inner clamping block 404, thus realizing the adjustment of the connection gap between the U-shaped rod 2 and the transport container.
