Description
Technical Field
[0001] This utility model relates to the field of locking technology, specifically a locking structure. Background Technology
[0002] In fields such as machinery, electronic products, and furniture assembly, the locking structure is a key component for enabling quick connection and separation of parts, and its performance directly affects the safety and convenience of using the equipment.
[0003] Existing locking structures have several drawbacks. In practical applications, such as logistics and transportation, after unlocking the container, operators sometimes do not open it immediately. Instead, they need to ensure the contents remain safe and stable during movement, handling, or other operations to prevent accidental opening of the lid due to touch or shaking, which could lead to items falling, damage, or even accidents. Most existing locking structures use a single locking method, which loses its locking constraint after unlocking. This makes it difficult to meet the requirement of maintaining the container's temporary closure after unlocking, thus hindering reliable protection of the contents.
[0004] Therefore, a locking structure is urgently needed to solve the above problems. Utility Model Content
[0005] Based on the above, the purpose of this utility model is to provide a locking structure to solve the problem that the locking structure cannot meet the constraint requirements after unlocking.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a locking structure, comprising:
[0007] The lower mounting plate has a first slot and a second slot on its side.
[0008] A mounting base is provided on the lower mounting plate;
[0009] The latch assembly includes a first lock body and a button. The first lock body is rotatably mounted on the fixed base. The locking end of the first lock body passes through the first bayonet from the fixed base. Rotating the first lock body can engage or disengage the lower mounting plate.
[0010] The button is spring-loaded onto the mounting base, and the locking end of the button protrudes from the second latch along the spring-loaded direction of the button; compressing the button unlocks the lower mounting plate, and releasing the button locks the lower mounting plate.
[0011] As a preferred embodiment of the locking structure, it further includes an upper mounting plate and a snap plate. The upper mounting plate is disposed on the top of the lower mounting plate. One end of the upper mounting plate near the lower mounting plate extends in a direction away from the lower mounting plate. The snap plate is connected to the fixing base and the upper mounting plate. The fixing base is rotatably connected to both the lower mounting plate and the snap plate.
[0012] As a preferred embodiment of the locking structure, the locking end of the first lock body passes through the fixing seat into the first latch, and the length of the first latch is greater than the length of the locking end of the first lock body and greater than the width of the first latch.
[0013] As a preferred embodiment of the locking structure, the locking end of the button is formed by a second lock body. The button is mounted on the side of the lower mounting plate and has a groove. The inner wall of the groove is symmetrically provided with opposite or opposing locking blocks. One end of the second lock body extends into the groove. The end of the second lock body extending into the groove is symmetrically provided with locking strips. The ends of the symmetrical locking strips are provided with opposite or opposing locking blocks. The locking blocks extend past the front of the locking blocks and are locked on the back of the locking blocks.
[0014] As a preferred embodiment of the locking structure, the other end of the second lock body passes through the second latch, and one end of the second lock body that passes through the second latch protrudes from the second latch. The protruding end of the second lock body protrudes in the direction of the button's rebound. The rebounded button at the protruding end of the second lock body can lock the fixing seat in the second latch, and the compressed button at the protruding end of the second lock body can release the fixing seat from the second latch.
[0015] As a preferred embodiment of the locking structure, the fixed base and the button are connected by an elastic element, which is used for unlocking or locking the fixed base and the lower mounting plate.
[0016] As a preferred embodiment of the locking structure, a pad is provided on the side of the lower mounting plate where the first slot is opened, and the pad is used to support the first lock body.
[0017] As a preferred embodiment of the locking structure, the lower mounting plate has a groove on its back away from the fixing seat, and both the first latch and the second latch are located in the groove.
[0018] As a preferred embodiment of the locking structure, the button has a hole on its side, and a stop block runs through the middle of the hole. The second lock body has a vertical block in the middle of the locking strip, which is symmetrical to the second lock body and is used to cooperate with the stop block.
[0019] As a preferred embodiment of the locking structure, the inner wall of the groove is symmetrically provided with guide blocks, which are arranged parallel to the locking block on the inner wall of the groove.
[0020] The beneficial effects of this utility model are as follows: the dual locking mechanism of the first lock body and the button allows the box to remain temporarily closed after unlocking. The rotary first lock body provides stable basic connection strength through its mechanical structure that tightly engages with the lower mounting plate, effectively resisting shaking and impact during movement and handling; the rebound button, even in the unlocked state, can still use the rebound force of the elastic element to keep the second lock body moderately locked to the fixed seat, forming an auxiliary constraint. This double protection prevents the box lid from opening by accidental contact, providing all-round safety protection for the items inside the box. Attached Figure Description

[0037] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.
[0038] In one embodiment of this utility model, such as Figure 1-7As shown, a locking structure is provided, including: a lower mounting plate 1, a fixing base 2, and a locking assembly 3. The lower mounting plate 1 has a first latch 101 and a second latch 102 on its side. The fixing base 2 is disposed on the lower mounting plate 1. The locking assembly 3 includes a first lock body 301 and a button 302. The first lock body 301 is rotatably disposed on the fixing base 2, and the locking end of the first lock body 301 passes through the first latch 101 from the fixing base 2. Rotating the first lock body 301 engages or disengages the lower mounting plate 1. The button 302 is spring-loaded and disposed on the fixing base 2. The locking end of the button 302 protrudes from the second latch 102 along the spring-loaded direction of the button 302. Compressing the button 302 unlocks the lower mounting plate 1, and releasing the button 302 locks the lower mounting plate 1.
[0039] The locking structure provided by this utility model, through the dual locking mechanism of the first lock body 301 and the button 302, enables the box to remain temporarily closed after unlocking. The rotary first lock body 301, through its mechanical structure that tightly engages with the lower mounting plate 1, provides a stable basic connection strength, effectively resisting shaking and impact during movement and handling; the rebound button 302, even in the unlocked state, can still use the rebound force of the elastic element 17 to keep the second lock body 13 moderately locked to the fixed seat 2, forming an auxiliary constraint. This double protection prevents the box lid from opening by accidental contact, providing all-round safety protection for the items inside the box.
[0040] In this embodiment, the fixing seat 2 can be directly installed on the lid, and the lower mounting plate 1 can be installed on the box body. When the fixing seat 2 is unlocked and the lower mounting plate 1 is locked, the box can be sealed.
[0041] The locking structure also includes an upper mounting plate 4 and a buckle plate 5. The upper mounting plate 4 is disposed on the top of the lower mounting plate 1. The end of the upper mounting plate 4 near the lower mounting plate 1 extends in a direction away from the lower mounting plate 1. The buckle plate 5 is connected to the fixing base 2 and the upper mounting plate 4. The fixing base 2 is rotatably connected to the lower mounting plate 1 and the buckle plate 5.
[0042] In this embodiment, the lower mounting plate 1 is installed on the box body, and the upper mounting plate 4 is installed on the box cover. The snap plate 5 and the fixing seat 2 form a snap fastener. By unlocking the fixing seat 2, the snap plate 5 can be detached from the upper mounting plate 4. In some embodiments, the box cover can be flipped open at both ends of the box body. Both box covers and the box body can be connected by installing the lower mounting plate 1, the upper mounting plate 4, the fixing seat 2, and the snap plate 5 to achieve a double-opening box method. Alternatively, in other embodiments, direct combination and interchange are also possible. For example, the box cover can be equipped with the lower mounting plate 1, and the box body can be equipped with the upper mounting plate 4.
[0043] Preferably, a pad 6 is provided on the side of the lower mounting plate 1 where the first latch 101 is opened. The pad 6 fills the gap between the locking end of the first lock body 301 and the lower mounting plate 1 caused by manufacturing tolerances or assembly gaps, so that when the first lock body 301 is rotated to the locked position, it can fit tightly against the lower mounting plate 1, thereby achieving effective tensioning of the fixing seat 2 and the lower mounting plate 1.
[0044] Preferably, the lower mounting plate 1 has a groove 7 on its back away from the fixing base 2, and the first latch 101 and the second latch 102 are both located in the groove 7. The groove 7 can hide the first latch 101 and the second latch 102, preventing the latches from being blocked or damaged, ensuring that the locking ends of the first lock body 301 and the button 302 can smoothly cooperate with the latches, and improving the performance and stability of the latch structure.
[0045] Preferably, the locking end of the first lock body 301 passes through the fixing base 2 into the first latch 101, and the length of the first latch 101 is greater than the length of the locking end of the first lock body 301 and greater than the width of the first latch 101. Specifically, the width of the locking end of the first lock body 301 is less than the length of the locking end of the first lock body 301, and the width of the locking end of the first lock body 301 is less than the width of the first latch 101.
[0046] In this embodiment, the first lock body 301 can be configured as a keyhole equipped with a key, according to the user's needs.
[0047] In this embodiment, this dimensional design allows the locking end of the first lock body 301 to rotate and engage within the first latch 101. The length of the first latch 101 is greater than the length of the locking end of the first lock body 301, providing sufficient space for the locking end of the first lock body 301 to enter and exit; the length of the locking end of the first lock body 301 is greater than the width of the first latch 101, enabling rotational locking of the locking end; the width of the locking end of the first lock body 301 is less than its length, and the width of the locking end of the first lock body 301 is less than the width of the first latch 101. This ensures that the locking end can smoothly insert into and exit the first latch 101.
[0048] Preferably, the locking end of the button 302 is formed by a second lock body 13. The button 302 is mounted on the side of the lower mounting plate 1 and has a groove 8. Symmetrically arranged opposite or back-to-back locking blocks 9 are provided on the inner wall of the groove 8. One end of the second lock body 13 extends into the groove 8, and symmetrically arranged locking strips 10 are provided at the end of the second lock body 13 extending into the groove 8. The ends of the symmetrical locking strips 10 have back-to-back or oppositely extending locking blocks 11, which extend past the front of the locking block 9 and engage with the back of the locking block 9. Through the cooperation of the locking block 9 and the locking block 11, a reliable connection between the second lock body 13 and the button 302 is achieved. This structure allows the second lock body 13 to move with the pressing and rebounding action of the button 302. Simultaneously, the engagement of the locking block 11 and the locking block 9 prevents the second lock body 13 from disengaging during the operation of the button 302, ensuring the normal functioning of the button 302 and improving the stability and reliability of the latch structure.
[0049] Preferably, guide blocks 12 are symmetrically provided on the inner wall of the groove 8, and the guide blocks 12 are arranged parallel to the locking block 11 on the inner wall of the groove 8. The guide blocks 12 can guide the second lock body 13 when it is inserted into and withdrawn from the groove 8, so that the second lock body 13 can move smoothly along the guide block 12, thereby realizing the quick installation of the second lock body 13 and the button 302.
[0050] Preferably, one end of the second lock body 13 passes through the second latch 102, and the end of the second lock body 13 passing through the second latch 102 protrudes from the second latch 102. The protruding end of the second lock body 13 protrudes in the direction of the rebound of the button 302. The rebounding button 302 at the protruding end of the second lock body 13 can lock the fixing seat 2 into the second latch 102, and the compressed button 302 at the protruding end of the second lock body 13 can release the fixing seat 2 from the second latch 102. The protruding end of the second lock body 13 allows the button 302 to lock and unlock the fixing seat 2 through simple pressing and rebounding operations. When rebounding, the protruding end is locked into the second latch 102, achieving locking; when compressed, the protruding end disengages from the second latch 102, achieving unlocking. This is convenient and quick to operate, improving the efficiency of the locking structure.
[0051] Preferably, the button 302 has a hole 14 on its side, and a stop 15 passes through the middle of the hole 14. The second lock body 13 has a vertical block 16 in the middle of the symmetrical locking strip 10, which is used to cooperate with the stop 15. The cooperation between the stop 15 and the vertical block 16 ensures the structural stability of the second lock body 13, allowing the second lock body 13 to be tightly installed on the button 302. This improves the stability of unlocking or locking when the button 302 is pressed.
[0052] Preferably, the fixing base 2 and the button 302 are connected by an elastic element 17, which can be made of a spring. The elastic element 17 can provide a restoring force to the button 302, so that the button 302 can automatically rebound after being pressed, realizing a quick locking function.
[0053] The unlocking or locking steps in this embodiment are as follows: rotate the first lock body 301 so that its locking end rotates within the first latch 101, thereby releasing or locking the first lock body 301 from the engagement or disengagement state of the fixed seat 2 and the lower mounting plate 1.
[0054] In this embodiment, after unlocking, the steps for opening or sealing the box according to actual needs are as follows: compress or release button 302, button 302 drives the second lock body 13 to overcome the rebound force of elastic member 17, or release elastic member 17, so that the second lock body 13 slides along the second bayonet 102, and the protruding end of the second lock body 13 disengages from or is stuck in the second bayonet 102.
[0055] In this embodiment, after unlocking, the step of opening the box according to actual needs is as follows: compress button 302, button 302 drives the second lock body 13 to overcome the rebound force of elastic element 17, so that the second lock body 13 slides along the second bayonet 102, and the protruding end of the second lock body 13 disengages from the second bayonet 102, thus completing the unlocking operation of the fixed seat 2.
[0056] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
