Description

Technical Field

[0001] This utility model relates to the field of lock technology, and more specifically, to a container lock with a quick-connect structure. Background Technology

[0002] Container locks are a key component for ensuring the safety of cargo transportation and are widely used in multimodal transport scenarios such as road, rail, and sea transport. Their core function is to achieve a stable connection between containers and transport carriers such as trucks, container ships, and railway flatcars, preventing cargo from shifting due to bumps and swaying during transportation.

[0003] Existing publication number CN205150774U discloses a container lock that is simple to operate and highly secure. It includes a key and a lock. The key includes a key bar with a key head at one end. The lock includes a lock block and a locking element that cooperates with the lock block. A groove is formed on the lock block, and a through hole is formed at the bottom of the groove. The groove opening is elongated, and when viewed along the extension direction of the groove opening, the cross-section of the groove space surrounded by the groove forms a convex shape. The locking element includes a cylindrical lock rod and a locking head located at one end of the lock rod. An operating head, operated by the key head, is formed at the other end of the lock rod. The locking head can be inserted into the groove space from the groove opening of the lock block and locked inside the groove. A locking flange, spaced apart from the locking head, is installed on the lock rod. In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: Existing container locks are obviously cumbersome in daily use. Some models require the external protective parts to be removed first, and then the core structure to be loosened with special tools. The operation steps are numerous and labor-intensive, which can easily delay the overall transportation time, especially when stopping for inspection during road transport. Therefore, a container lock with a quick-connect structure is proposed to address the above problems. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a container lock with a quick-connect structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a container lock with a quick-connect structure, comprising a container body, wherein multiple hinges are installed on the top of the container body; bolts are threadedly connected to the top of the hinges; a container door is installed at the bottom of the hinges; the container door is located in the middle of the container body; multiple locking components are installed on the surface of the container door; a limit component is provided on the top of the container body; and a sealing component is provided in the middle of a pair of the container doors.

[0006] Preferably, a limiting plate is fixedly attached to the surface of the container door; one end of the limiting plate is located at the top of the container body.

[0007] Preferably, the locking component includes a connecting box; the connecting box has multiple limiting holes in its center; a first mounting block is provided on the top of the connecting box; a first rotating shaft is installed in the center of the first mounting block; the first rotating shaft rotates in a preset hole groove in the center of the first mounting block; a connecting plate is fixedly connected to the surface of the first rotating shaft; multiple limiting rods are fixedly connected to one side of the connecting plate; the limiting rods slide in the center of the limiting holes.

[0008] Preferably, a first magnetic block is fixedly connected to the end of the limiting rod; a second magnetic block is fixedly connected to the inner wall of the limiting hole.

[0009] Preferably, the limiting component includes a second mounting block; a second rotating shaft is provided in the middle of the second mounting block; the second rotating shaft rotates in a preset hole groove in the middle of the second mounting block; a telescopic rod is fixedly connected to the surface of the second rotating shaft; a limiting block is fixedly connected to the top of the container body; a sliding groove is provided in the middle of the limiting block; the telescopic rod slides in the middle of the sliding groove; and a slot is provided on the surface of the connecting box.

[0010] Preferably, a handrail is fixedly connected to the end of the telescopic rod; the surface of the handrail is provided with multiple anti-slip textures.

[0011] Preferably, the sealing assembly includes a magnetic strip and a rubber pad; the magnetic strip is located at the end of the door; and the rubber pad is located at the bottom of the magnetic strip.

[0012] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this container lock with a quick-connect structure solves the problem of cumbersome use of existing locks by using the quick-lock design of the locking component and the leverage operation of the handrail, combined with the convenient positioning of the second mounting block's sliding groove. It does not require disassembling external protective components; simply operate the handrail to extend the telescopic rod, allowing it to slide in the sliding groove and engage with the slot for positioning. When activating the locking component, only the first rotating shaft needs to be rotated to drive the connecting plate, causing the limiting rod to slide in the limiting hole and engage with the first and second magnetic blocks for magnetic locking. No special tools are required throughout the process. During inspections in road transport, the simplified operation steps significantly shorten adjustment time, avoiding delays caused by disassembling protective components and searching for tools. This makes lock adjustment more efficient and labor-saving, meeting the needs of high-frequency turnover scenarios.

[0013] Compared to existing technologies, this container lock with a quick-connect structure achieves integrated lock adjustment and sealing by combining real-time limiting of the limiting plate with synchronous sealing of the sealing components, along with the coordinated operation of the locking and limiting components. Existing technologies require separate handling of lock locking and position calibration. During operation, the limiting plate moves with the container door in real-time, eliminating the need for additional adjustments. The magnetic attraction of the magnetic strip and the sealing of the rubber gasket in the sealing component are completed simultaneously, avoiding separate sealing issues later. Furthermore, the locking of the locking component and the positioning of the limiting component do not require separate operations, significantly reducing operational steps. This not only eliminates the need for special tools and disassembly of protective components but also achieves locking, positioning, and sealing, further improving the efficiency of highway inspections and reducing the risk of transportation delays.

Example 2

[0022] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details: In a preferred embodiment, a limiting plate 2 is fixedly attached to the surface of the container door 13; when the container door 13 closes toward the container body 1, the limiting plate 2 moves synchronously with the container door 13, and when the container door 13 is close to the closed position, the limiting plate 2 contacts the top of the container body 1; one end of the limiting plate 2 is located at the top of the container body 1; the limiting plate 2 restricts the excessive displacement of the container door 13 by physical blocking, ensuring that the container door 13 is accurately connected with the container body 1, and at the same time helps to maintain the stable posture of the container door 13 after it is closed, so as to prevent the container door 13 from shifting due to transportation bumps.

[0023] In a preferred embodiment, the locking assembly 14 includes a connecting box 3; the connecting box 3 has multiple limiting holes 31 in its middle; when the first rotating shaft 33 is rotated, it drives the fixed connecting plate 34 to move; a first mounting block 32 is provided on the top of the connecting box 3; the first rotating shaft 33 is installed in the middle of the first mounting block 32; the first rotating shaft 33 rotates in a preset slot in the middle of the first mounting block 32; the connecting plate 34 is fixedly connected to the surface of the first rotating shaft 33; the connecting plate 34 then pulls the limiting rod 35 to slide in the limiting hole 31 of the connecting box 3, so that the limiting rod 35 extends or retracts; multiple limiting rods 35 are fixedly connected to one side of the connecting plate 34; when the connecting plate 34 extends, it can be locked into the corresponding structure, and when it retracts, it unlocks the limiting rod 35 sliding in the middle of the limiting hole 31; wherein the limiting hole 31 guides the limiting rod 35 to ensure accurate sliding and avoid deviation.

[0024] In a preferred embodiment, a first magnetic block 4 is fixedly connected to the end of the limiting rod 35; when the limiting rod 35 slides out in the limiting hole 31, the first magnetic block 4 moves synchronously with the limiting rod 35 until it is precisely aligned with the second magnetic block 41; the second magnetic block 41 is fixedly connected to the inner wall of the limiting hole 31; the two are tightly attracted by magnetic attraction, forming a double fixation.

[0025] In a preferred embodiment, the limiting component 15 includes a second mounting block 5; the end of the limiting block 53 is first stretched to elongate it; a second rotating shaft 51 is provided in the middle of the second mounting block 5; the telescopic rod 52 gradually enters the middle of the sliding groove 54 opened in the limiting block 53; the second rotating shaft 51 rotates in the preset hole groove in the middle of the second mounting block 5; the telescopic rod 52 is fixedly connected to the surface of the second rotating shaft 51; during this process, the surface of the telescopic rod 52 precisely engages with the middle of the slot 55 to form a double positioning; the top of the container body 1 is fixedly connected to the limiting block 53; the telescopic rod 52 achieves its own position fixation by stretching in the sliding groove 54, and the position of the connecting box 3 is limited and constrained by the engagement structure of the telescopic rod 52 and the slot 55; the limiting block 53 has a sliding groove 54 in the middle; the telescopic rod 52 slides in the middle of the sliding groove 54; the surface of the connecting box 3 has a slot 55; this setting prevents the connecting box 3 from shifting during subsequent operation or transportation, and indirectly guides the box door 13 to accurately engage with the closed position of the container body 1.

[0026] In a preferred embodiment, a handrail 6 is fixedly connected to the end of the telescopic rod 52; the handrail 6 is the core lever for stretching the telescopic rod 52; the surface of the handrail 6 is provided with multiple anti-slip textures 61; when it is necessary to adjust the position of the telescopic rod 52, the operator holds the handrail 6 and applies pulling or pushing force, and the force is transmitted to the telescopic rod 52 through the handrail 6, which directly drives the telescopic rod 52 to slide in the groove 54 of the limiting block 53, thereby realizing the stretching and resetting of the telescopic rod 52, and then cooperating with the slot 55 to complete the positioning or limit the connection box 3.

[0027] In a preferred embodiment, the sealing assembly 16 includes a magnetic strip 7 and a rubber pad 8; the rubber pad 8 is correspondingly disposed at the fitting gap between the container body 1 and the door 13; the magnetic strip 7 is located at the end of the door 13; the rubber pad 8 is located at the bottom of the magnetic strip 7; when the door 13 closes to the container body 1, the magnetic strip 7 attracts the corresponding part of the container body 1 by means of magnetic attraction, pulling the door 13 to precisely fit the container body 1, while the rubber pad 8 is squeezed between the container body 1 and the door 13, filling the gap and forming an elastic sealing layer, blocking the external airflow and moisture passage.

[0028] In this embodiment, the magnetic strip 7, telescopic rod 52, etc. are all commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, and we will not go into detail here.

[0029] The working process of this utility model is as follows: First, operate the locking component 14. Under the action of the rotation of the first rotating shaft 33, the connecting plate 34 drives the limiting rod 35 to move, so that the first magnetic block 4 at the end of the limiting rod 35 magnetically engages with the second magnetic block 41 on the inner side wall of the connecting box 3. At the same time, the limiting rod 35 is inserted into the limiting hole 31 of the connecting box 3 and the box door 13, which enhances the locking stability. Then, the handle 6 with anti-slip texture 61 can be pulled forward. At this time, the telescopic rod 52 extends until the end of the telescopic rod 52 passes through the middle of the slide groove 54. At this time, the surface of the telescopic rod 52 is stuck in the middle of the slot 55, which limits the connecting plate 34. This can realize the quick locking and unlocking of the box door 13 and the container body 1. When it is no longer needed, push the handle 6 to retract the telescopic rod 52, which can unlock and store the connecting box 3.

[0030] When the container door 13 is closed, the sealing component 16 plays a key role. The magnetic strip 7 cooperates with the rubber pad 8. The magnetic strip 7 magnetically assists the container door 13 to close in place. At this time, the rubber pads 8 are in close contact with each other, which plays a sealing and buffering role and improves the sealing performance. In addition, the limiting plate 2 limits the container door 13, and the hinge 11 and bolt 12 ensure the basic stability of the connection between the container door 13 and the container body 1. The above is the working principle of this container lock with quick-connect structure.
