Description

Technical Field

[0001] The utility model belongs to the technical field of containers, in particular to a door lock assembly and a container with the door lock assembly. Background Art

[0002] Containers are widely used in cargo transportation. They have the advantages of being easy to load and unload and not easily damaged. They play an important role in both ocean and land transportation.

[0003] For traditional containers, when opening the door, the operator pulls the door outward, causing the cross braces to compress the flexible element, resulting in an elastic deformation of bending forward. The pair of cross braces move from the rear to the front of the locking mechanism, thus opening the door. When closing the door, the operator pushes the door inward, causing the cross braces to compress the flexible element, resulting in an elastic deformation of bending backward. The pair of cross braces move from the front to the rear of the locking mechanism, and the flexible element returns to its original state, thus closing the door. The flexible element also ensures that the door remains locked under normal conditions.

[0004] However, the flexible elements in the aforementioned traditional container door lock assemblies are made of elastic rubber. After a certain number of opening and closing cycles, the elastic deformation of these elements can lead to plastic deformation, making the door susceptible to accidental opening even when locked. This compromises the container's safety, and environmental factors can accelerate the aging of the flexible elements. Furthermore, the base plate is typically fixed to the crossbeam using welding or threaded fasteners. When the locking mechanism ages and becomes unusable, the entire frame and its attachment to the locking mechanism must be removed and replaced, resulting in low efficiency.

[0005] Therefore, there is an urgent need for a door lock assembly and a container having the door lock assembly that can solve the above problems. Utility Model Content

[0006] To solve the above problems, this utility model proposes a door lock assembly, including a door attachment lock and a frame attachment lock, wherein the door attachment lock is fixedly installed on the front end face of the door body, and the frame attachment lock is fixedly installed on the front end face of the box frame.

[0007] The door attachment lock comprises a longitudinal base column fixedly mounted on the front face of the door body, and both ends of the longitudinal base column are provided with passive locks matching the frame attachment lock;

[0008] The passive locking element comprises a base element coaxially arranged with the longitudinal base column, a pair of parallel horizontal braces are provided on one side of the base element, and a locking groove is formed between the pair of horizontal braces;

[0009] The frame attachment locking device includes a base plate fixedly installed on the front end face of the box frame, and a locking plate extending forward is provided on the front end face of the base plate away from the box frame, wherein an actuating locking device is provided at the front end of the locking plate.

[0010] Among them, the action lock includes a lock body fixedly installed at the front end of the locking plate, and flexible elements are arranged at both the upper and lower ends of the lock body.

[0011] The lock body has configuration slots at both the top and bottom, and the flexible element is slidably installed in the configuration slot. A spring element is installed in the configuration slot, with one end of the spring element connected to the bottom surface of the configuration slot and the other end connected to the bottom surface of the flexible element.

[0012] Furthermore, the flexible element includes a guide portion and an action portion extending from the guide portion in a direction away from the lock body, and the shape and size of the guide portion match the configuration groove.

[0013] The front and rear sides of the functional part are both configured as inclined surfaces.

[0014] Furthermore, the side of the guide section is provided with elastic protrusions;

[0015] The configuration slots are set in a stepped shape, with the end closer to the bottom being a large slot and the end further away from the bottom being a small slot;

[0016] When the elastic protrusion is in its original protruding position, it contacts the side of the large groove, and the size of the guide part matches the small groove.

[0017] Furthermore, the guide section has a through groove, and a pair of elastic protrusions are slidably mounted at both ends of the through groove;

[0018] A spring is installed inside the through groove, and the two ends of the spring are respectively connected to the bottom end face of a pair of elastic protrusions.

[0019] Furthermore, a pair of parallel second cross braces are provided on the other side of the base component, wherein the pair of second cross braces are spaced apart, and the gap between them forms a second locking groove;

[0020] The front end of the base plate, away from the housing frame, is also provided with a forward-extending guide plate.

[0021] Furthermore, the box frame is provided with several notches, and upper and lower mounting plates are fixedly installed at the upper and lower ends of the notches, respectively.

[0022] The hinge assembly includes a hinge body and a pin element. The hinge body includes a door connecting part and a longitudinal post connecting part, and the door connecting part and the longitudinal post connecting part are integrally formed into an L-shape.

[0023] The door connecting part is fixedly installed on the front end face of the door body, and the longitudinal column connecting part is rotatably installed between the upper and lower mounting plates through a pin element.

[0024] Furthermore, both the upper and lower mounting plates are provided with coaxial mounting holes, and the longitudinal column connecting part is provided with a hinged through hole coaxial with the mounting holes.

[0025] The pin shaft element is sequentially installed through the upper mounting plate, the longitudinal column connection part, and the lower mounting plate.

[0026] This utility model also provides a container, including a container frame and the aforementioned door lock assembly installed on the front end face of the container frame;

[0027] The box frame includes crossbeams and longitudinal columns, and the frame is fixedly installed on the front end face of the crossbeams with a lock attached, and the door is hinged to the front end face of the longitudinal columns via a hinge assembly.

[0028] When the door is closed, the front face of the door is flush with the front face of the crossbeam.

[0029] Furthermore, the door body includes a left door body and a right door body, with the left door body hinged to the left longitudinal column and the right door body hinged to the right longitudinal column.

[0030] Furthermore, several gaps are created in the longitudinal columns.

[0031] Compared with the prior art, the advantages of the present invention are:

[0032] 1. The flexible element uses the action of the spring element to produce "movement deformation". The reliability and durability of the spring element are higher than the traditional flexible element made of elastic rubber material, thereby increasing the service life of the action lock, preventing the door from being accidentally opened when locked, and improving the safety of the container.

[0033] 2. The lock body at the small groove forms an inner protrusion, which limits the elastic protrusion to ensure that the flexible element is always partially located in the configuration groove under normal conditions, preventing the flexible element from escaping from the lock body.

[0034] 3. When the spring element in the action lock degrades and becomes unusable, simply remove the flexible element to replace it, then push the flexible element back into the slot. This eliminates the need to completely remove the frame-attached lock for replacement, saving costs. Furthermore, there's no need to re-weld the frame-attached lock or remove and install threaded fasteners, making replacement more efficient.

[0035] 4. The utility model forms a hidden installation of the pin element, and the pin element does not protrude from the longitudinal column, which saves installation space and prevents foreign objects from hitting the pin element during the transportation of the container, greatly improving the service life of the hinge assembly.

DETAILED DESCRIPTION

[0047] To make the objectives, technical solutions, and advantages of this application clearer, the application is described and illustrated below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. All other embodiments obtained by those skilled in the art based on the embodiments provided in this application without inventive effort are within the scope of protection of this application.

[0048] like Figure 1-9 As shown, this embodiment provides a container, including a container frame 100 and a door lock assembly 200 mounted on the front end face of the container frame 100. Specifically, the door lock assembly 200 includes a door 210 and a hinge assembly 300, so that the door 210 is hingedly mounted to the front end face of the container frame 100 via the hinge assembly 300; the door lock assembly 200 also includes a door attachment lock 400 and a frame attachment lock 500, so as to ensure that the door 210 can be locked to the container frame 100.

[0049] It is understood that the door attachment lock 400 is fixedly installed on the front end face of the door body 210, and the frame attachment lock 500 is fixedly installed on the front end face of the container frame 100, and the door attachment lock 400 and the frame attachment lock 500 are matched. In other words, the container frame 100 of this embodiment includes a crossbeam 110 and a longitudinal column 120, wherein the frame attachment lock 500 is fixedly installed on the front end face of the crossbeam 110, and the door body 210 is hinged to the front end face of the longitudinal column 120 through a hinge assembly 300. When the door body 210 is in the closed state, the front end face of the door body 210 is flush with the front end face of the crossbeam 110. Preferably, the container of this embodiment adopts a double-door configuration, with the door body 210 including a left door body 211 and a right door body 212, and the left door body 211 is hinged to the left longitudinal column 120, and the right door body 212 is hinged to the right longitudinal column 120.

[0050] It should be noted that the crossbeam 110 includes an upper crossbeam and a lower crossbeam, and the front end face of both the upper and lower crossbeams is equipped with a frame attachment lock 500 that matches the door attachment lock 400, so as to improve the stability of the door 210 in the locked state.

[0051] In this embodiment, the door attachment lock 400 includes a longitudinal base post 410 fixedly installed on the front end face of the door body 210, with the upper end of the longitudinal base post 410 extending upward to the upper end face of the door body 210 and the lower end of the longitudinal base post 410 extending downward to the lower end face of the door body 210. Both ends of the longitudinal base post 410 are provided with passive locks 420 that match the frame attachment lock 500.

[0052] Specifically, the passive locking member 420 includes a base member 421 coaxially arranged with the longitudinal base column 410, and a pair of parallel cross braces 422 are provided on one side of the base member 421, wherein the pair of cross braces 422 are spaced apart, and the gap between them forms a locking groove 423; correspondingly, the frame attachment locking member 500 includes a base plate 510 fixedly installed on the front end face of the cross beam 110, and a forward-extending locking plate 520 is provided on the front end face of the base plate 510 away from the cross beam 110, wherein an actuating locking member 530 is provided at the front end of the locking plate 520.

[0053] Understandably, the longitudinal width of the locking plate 520 matches the width of the locking groove 423 so that the locking plate 520 can enter the gap between a pair of cross braces 422; the actuating locking member 530 includes a locking member body 531 fixedly installed at the front end of the locking plate 520, and flexible elements 532 extend from both the upper and lower ends of the locking member body 531. The locking member body 531 and the flexible elements 532 are both matched with the width of the locking groove 423 so that a pair of cross braces 422 can move from one side of the actuating locking member 530 to the other side.

[0054] In other words, the longitudinal width of the locking plate 520 and the locking body 531 is smaller than the width of the locking groove 423, so that when the door 210 is in the locked state, a pair of cross braces 422 can be located on the rear side of the actuating locking member 530; the conventional flexible element 532 is elastic and is integrally formed with the locking body 531, so that when a pair of cross braces 422 move from the front (or rear) side of the actuating locking member 530 to the rear (or front) side, the flexible element 532 produces elastic deformation in the same direction as the movement of the cross braces 422 under the pressure of the cross braces 422, and the cross braces 422 can move from one side of the actuating locking member 530 to the other side. After the movement is completed, the flexible element 532 returns to its original state.

[0055] Therefore, when the container door is opened, the operator pulls the door 210 outward, the longitudinal base column 410 drives the passive locking member 420 to move from the rear to the front of the actuating locking member 530, the cross brace 422 compresses the flexible element 532 to produce an elastic deformation in a bending state, and the pair of cross braces 422 move from the rear to the front of the actuating locking member 530, thus opening the door; when the container door is closed, the operator pushes the door 210 inward, the longitudinal base column 410 drives the passive locking member 420 to move from the front to the rear of the actuating locking member 530, the cross brace 422 compresses the flexible element 532 to produce an elastic deformation in a bending state, and the pair of cross braces 422 move from the front to the rear of the actuating locking member 530, the flexible element 532 returns to its original state, thus closing the door, and the flexible element 532 can ensure that the door 210 is locked under normal conditions.

[0056] However, in the aforementioned traditional container door lock assembly, the flexible element 532 is made of elastic rubber. After a certain number of opening and closing cycles, the elastic deformation of the flexible element 532 can cause plastic deformation, making the door 210 easily opened accidentally when locked, affecting the safety of the container. This is especially true as environmental factors accelerate the aging of the flexible element 532. Furthermore, the base plate 510 is typically fixed to the crossbeam 110 using welding or threaded fasteners. When the locking mechanism 530 ages and becomes unusable, the entire frame-attached locking mechanism 500 needs to be removed and replaced, which is inefficient.

[0057] To eliminate the above-mentioned defects, in this embodiment, the door lock assembly 200 has a configuration slot 533 at both the upper and lower ends of the lock body 531, and the flexible element 532 is slidably installed in the configuration slot 533. A spring element 534 is installed in the configuration slot 533, and one end of the spring element 534 is connected to the bottom surface of the configuration slot 533, and the other end is connected to the bottom surface of the flexible element 532.

[0058] Thus, when a pair of cross braces 422 move from the front (or rear) side of the actuating lock 530 to the rear (or front) side, under the pressure of the cross braces 422, the flexible element 532 will overcome the elastic force of the spring element 534 and retract into the configuration slot 533. The cross braces 422 can move from one side of the actuating lock 530 to the other side. After the movement is completed, the flexible element 532 returns to its original state under the elastic force of the spring element 534.

[0059] Through the above configuration, the flexible element 532 utilizes the action of the spring element 534 to generate "movement deformation." The reliability and durability of the spring element 534 are higher than those of the traditional flexible element 532, which uses elastic rubber material. This improves the service life of the locking mechanism 530, prevents the door 210 from being accidentally opened when locked, and enhances the safety of the container. Preferably, both the front and rear sides of the flexible element 532 are configured as inclined surfaces 535 so that the force exerted by the cross brace 422 on the flexible element 532 can generate a vertical component force.

[0060] Specifically, the flexible element 532 includes a guide portion 536 and an action portion 537 extending from the guide portion 536 in a direction away from the lock body 531. The shape and size of the guide portion 536 match the configuration groove 533 so that the flexible element 532 can be slidably installed in the configuration groove 533. The front and rear sides of the action portion 537 are both configured as inclined surfaces 535.

[0061] In this embodiment, to ensure that the flexible element 532 remains at least partially within the configuration slot 533, a resilient protrusion 538 is provided on the side of the guide portion 536. Accordingly, the configuration slot 533 is configured in a stepped manner, with a large slot 539 at the end closest to the bottom and a small slot 540 at the end further from the bottom. When in its original protruding position, the resilient protrusion 538 contacts the side of the large slot 539, and the dimensions of the guide portion 536 match those of the small slot 540.

[0062] Thus, the locking body 531 at the small groove 540 forms an inner protrusion 541. By limiting the elastic protrusion 538 through the inner protrusion 541, the flexible element 532 is always partially located in the configuration groove 533 under normal conditions, which prevents the flexible element 532 from detaching from the locking body 531.

[0063] It is worth noting that while the lock element 530, which utilizes the spring element 534, has a long service life, it may still require replacement. In the door lock assembly 200 of this embodiment, when the performance of the spring element 534 deteriorates to the point where replacement is necessary, the flexible element 532 can be simply pulled outward. The inner protrusion 541 retracts the elastic protrusion 538, allowing the flexible element 532 to be removed for replacement. After replacement, the flexible element 532 can then be pushed back into the configuration slot 533.

[0064] With this arrangement, when the spring element 534 in the action lock 530 degrades and becomes unusable, the user only needs to remove the flexible element 532 to replace the spring element 534. After the replacement is complete, the flexible element 532 can be pushed back into the configuration slot 533. This eliminates the need to completely remove the frame attachment lock 500 for replacement, saving costs. Furthermore, there's no need to re-weld the frame attachment lock 500 or remove and install threaded fasteners, making replacement more efficient.

[0065] Specifically, the guide portion 536 defines a through-slot 542, and a pair of elastic protrusions 538 are slidably mounted at either end of the through-slot 542. A spring 543 is also mounted within the through-slot 542, with both ends of the spring connected to the bottom end surfaces of the pair of elastic protrusions 538. Consequently, under the action of the spring 543, the pair of elastic protrusions 538 are in their original protruding position, cooperating with the inner protrusion 541 to prevent the flexible element 532 from disengaging the configuration slot 533. When the spring element 534 needs to be replaced and an external force is applied to the flexible element 532, the pair of elastic protrusions 538 can overcome the elastic force of the spring 543 and retract into the through-slot 542.

[0066] In this embodiment, a pair of parallel second cross braces 424 are provided on the other side of the base member 421, wherein the pair of second cross braces 424 are spaced apart, and the gap between them forms a second locking groove 425; correspondingly, a forward-extending guide plate 550 is also provided on the front end face of the base plate 510 away from the crossbeam 110.

[0067] Understandably, the longitudinal width of the guide plate 550 matches the width of the second locking groove 425 so that the guide plate 550 can enter the gap between a pair of second cross braces 424, thereby improving the stability of the door attachment lock 400 relative to the frame attachment lock 500 when opening or closing the door.

[0068] In this embodiment, the longitudinal column 120 is provided with a plurality of notches 121, and the upper and lower ends of the notches 121 are respectively fixedly provided with an upper mounting horizontal plate 122 and a lower mounting horizontal plate 123; the hinge assembly 300 includes a hinge body 310 and a pin element 320, wherein the hinge body 310 includes a door connecting portion 311 and a longitudinal column connecting portion 312, and the door connecting portion 311 and the longitudinal column connecting portion 312 are integrally formed to form an L-shaped body, the door connecting portion 311 is fixedly installed on the front end surface of the door body 210, and the longitudinal column connecting portion 312 is rotatably installed between the upper mounting horizontal plate 122 and the lower mounting horizontal plate 123 through the pin element 320.

[0069] The above configuration results in a concealed installation of the pin element 320, which does not protrude from the longitudinal column 120, saving installation space and preventing external objects from bumping into the pin element 320 during container transportation, thus greatly improving the service life of the hinge assembly 300.

[0070] Specifically, both the upper mounting plate 122 and the lower mounting plate 123 are provided with coaxial mounting holes (not shown), and the longitudinal column connecting part 312 is provided with a hinge through hole (not shown) coaxial with the mounting holes. Thus, the pin element 320 passes through the upper mounting plate 122, the longitudinal column connecting part 312 and the lower mounting plate 123 in sequence to realize the hinge connection between the hinge body 310 and the longitudinal column 120.

[0071] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
