Description

Technical Field

[0001] This application relates to the technical field of latches, and in particular to a latch, lock, and housing structure. Background Technology

[0002] In the design and manufacturing process of the cabinet and door, the precise installation and adjustment of the latches is a crucial step, which requires determining the position of the latches.

[0003] The traditional approach involves first determining the latch's position through precise calculations, then drilling fixing holes at those positions, and finally directly securing the latch to these holes. However, if the calculations are inaccurate or there are errors during installation, the latch's position may be inaccurate, requiring the holes to be re-drilled for correction. Re-drilling not only increases manufacturing costs but may also compromise the structural strength of the door, affecting the overall product quality. Furthermore, even with accurate calculations, the latch's position may still require minor adjustments during actual installation due to various factors.

[0004] While some existing technologies attempt to achieve flexible adjustment of the latch position by installing adjusting nuts to achieve the desired assembly effect, this method brings many inconveniences in practice. Typically, the adjusting nut is located on the inside of the door, requiring frequent hand insertion into the door during adjustment, which is very inconvenient. This is especially true in confined spaces or complex structures, where this adjustment method presents significant difficulties. Furthermore, because the adjusting nut is usually small and concealed, it is prone to slipping or being damaged during operation, further increasing the difficulty and cost of installation.

[0005] In view of the above problems, the industry urgently needs a door latch structure that can simplify the installation process and improve installation accuracy. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this application is to provide a latch, lock and cabinet that can simplify the installation process and improve the installation accuracy to improve the installation efficiency and user experience of the cabinet door latch.

[0007] The above-mentioned objective of this application is achieved through the following technical solution:

[0008] A latch includes: a retaining ring, a second baffle, a first screw post, and a spring. The retaining ring has a bent portion and a first baffle. Both ends of the bent portion are connected to the first baffle. The first baffle has an adjusting threaded hole. The second baffle is fixedly disposed and has a through hole that faces the adjusting threaded hole. The second baffle also has a first through groove. The middle portion of the bent portion passes through the first through groove. The bent portion and the second baffle together form an insertion space. The first screw post passes through the through hole and is threadedly connected to the adjusting threaded hole. The end of the first screw post is located on the outside of a second end plate. The spring surrounds the first screw post, and both ends of the spring abut against the first baffle and the second baffle, respectively.

[0009] The present application is further configured such that the middle part of the second baffle is bent to form a turning part, the first through groove is opened on one side of the turning part, and a sliding groove is opened on the other side of the turning part, and the first baffle can slide into the sliding groove.

[0010] The present application further provides that the first baffle has two recesses opposite to each other, and a sliding part is formed between the two recesses, and the sliding part is disposed in the groove.

[0011] This application is further configured such that the dimensions of both sides of the sliding part are larger than the dimensions of the sliding groove, and the two sides of the sliding part are respectively disposed on both sides of the second baffle.

[0012] The present application further includes a fixing block, on which a countersunk hole and a second through groove are provided, the second through groove and the first through groove are opposite each other, and the middle part of the bent portion passes through the first through groove and the second through groove in sequence.

[0013] This application is further configured such that the countersunk hole and the through hole are directly opposite each other, and the first threaded post passes through the countersunk hole, the through hole and the adjusting threaded hole in sequence, with the countersunk hole forming a limit on the end of the first threaded post.

[0014] This application is further configured to include a second screw post, which is sequentially threadedly connected to the fixing block and the second baffle.

[0015] This application is further configured such that the first screw post and the second screw post are arranged in parallel.

[0016] A lock includes the aforementioned latch, and further includes a locking pin and a driving device, wherein the driving device drives the locking pin to pass through or disengage from the socket space.

[0017] A box structure includes the above-mentioned lock, and further includes a box door and a box body, wherein the latch is installed on the box body, and the lock pin and the drive device are installed on the box door.

[0018] This application further specifies that the housing includes a locking mounting plate, which is fixedly connected to the second baffle.

[0019] In summary, the beneficial technical effects of this application are as follows:

[0020] 1. This application achieves precise and convenient adjustment of the locking position by connecting the first screw post with the threaded hole of the adjustment threaded hole on the first baffle. The operator can directly adjust the first screw post without having to go deep into the inside of the box door to adjust the nut. This greatly simplifies the installation process and improves work efficiency. At the same time, because the adjustment process is intuitive and easy to control, it reduces the skill level required of the operator.

[0021] 2. This application ensures stable contact between the buckle and the second baffle by using a spring, which can effectively prevent loosening caused by vibration or external force even during long-term use.

[0022] 3. This application achieves the adjustment of the retaining ring position through the threaded connection between the first screw post and the adjusting threaded hole and the spring, avoiding repeated drilling, reducing costs, and enabling the adjustment of the screw post to quickly correct even minor deviations during installation, thus protecting the structural integrity of the door and extending the product's service life.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] like Figures 1-3 As shown, a latch includes a retaining ring 1, a second baffle 3, a first screw post 5, and a spring 6. The retaining ring 1 has a bent portion 11 and a first baffle 12. Both ends of the bent portion 11 are connected to the first baffle 12. The first baffle 12 has an adjusting threaded hole. The second baffle 3 is fixedly installed and has a through hole 33, which is directly opposite to the adjusting threaded hole. The second baffle 3 also has a first through groove 31, through which the middle of the bent portion 11 passes. The bent portion 11 and the second baffle 3 together form an insertion space. The first screw post passes through the through hole 33 and is threadedly connected to the adjusting threaded hole. The end of the first screw post is located on the outside of the second end plate. The spring 6 surrounds the first screw post 5, and both ends of the spring 6 abut against the first baffle 12 and the second baffle 3, respectively.

[0032] The buckle 1 is designed with a bent portion 11 and a first baffle 12. The two ends of the bent portion 11 are connected to the first baffle 12 by a bending process, forming a U-shaped structure. An adjustment threaded hole is provided on the first baffle 12 for subsequent connection and adjustment with the first screw post 5.

[0033] The second baffle 3 is a fixed component with a through hole 33 opposite to the adjusting threaded hole for the first screw post 5 to pass through. Furthermore, the second baffle 3 also has a first through groove 31, the shape and size of which are designed to allow the middle part of the bent portion 11 to pass through, thus allowing the retaining ring 1 a certain degree of freedom of movement relative to the second baffle 3. The bent portion 11 and the second baffle 3 together form an insertion space for inserting and fixing the locking pin 7 to form a lock.

[0034] The first screw post 5 is a slender rod. One end of the first screw post 5 is located outside the second baffle 3 after being tightened, so that its tightness can be adjusted manually.

[0035] The spring 6 is ring-shaped, with an inner diameter slightly larger than that of the first screw post 5, to ensure that the spring 6 can be securely wrapped around the first screw post 5. The two ends of the spring 6 are respectively tightly attached to the first baffle 12 and the second baffle 3. When the first screw post 5 is tightened, the spring 6 is compressed, providing a certain preload and elastic recovery capability for the latch, which helps to maintain the stability of the latch and adapt to objects of different sizes.

[0036] By adjusting the screw depth of the first screw post 5 in the adjusting threaded hole, the locking force of the lock can be easily adjusted, and the area of ​​the insertion space and the position of the buckle 1 can be adjusted. It is suitable for objects of different sizes and materials, improving the versatility and practicality of the lock.

[0037] The design of spring 6 provides the latch with additional preload and elastic recovery, ensuring that objects remain secure and do not fall off even during prolonged use or in vibrating environments, thus enhancing the reliability and safety of the latch.

[0038] The main components of the latch include a retaining ring 1, a second baffle 3, a first screw post 5, and a spring 6. The structure is simple and clear, easy to manufacture and assemble, reduces production costs, and is also easy to maintain and replace.

[0039] In a preferred embodiment, the middle part of the second baffle 3 is bent to form a turning part 35, the first through groove 31 is opened on one side of the turning part 35, and a sliding groove 32 is opened on the other side of the turning part 35, and the first baffle 12 can slide into the sliding groove 32.

[0040] The second baffle 3 is bent in the middle to form a bend 35. This bend 35 not only enhances the strength of the second baffle 3 but also increases the stability of the latch. On the other side of the bend 35, a groove 32 is formed. The groove 32 allows the first baffle 12 to slide into it and maintain a stable position within it. Through the cooperation of the first baffle 12 and the groove 32, the latch 1 can only move along the direction of the groove 32, limiting its freedom in other directions, thereby increasing the stability of the latch 1 and making the latch more secure and reliable.

[0041] The bend 35 in the middle of the second baffle 3 significantly enhances the overall strength of the latch, making it more robust and durable. At the same time, the groove 32 increases the stability of the retaining ring 1, thereby improving the reliability of the latch when locking objects.

[0042] Furthermore, the included angle between the two sides of the turning part 35 is 90°.

[0043] Furthermore, the first baffle 12 has two recesses 121 opposite to each other, and a sliding part 122 is formed between the two recesses 121. The sliding part 122 is located in the sliding groove 32.

[0044] Furthermore, the dimensions of both sides of the sliding part 122 are larger than the dimensions of the sliding groove 32, and the two sides of the sliding part 122 are respectively located on both sides of the second baffle 3.

[0045] Two recesses 121 are symmetrically arranged on both sides of the first baffle 12, forming a sliding portion 122 between them. The sliding portion 122 is tightly and stably embedded in the groove 32 of the second baffle 3.

[0046] It is worth noting that the dimensions of both sides of the sliding part 122 are larger than the dimensions of the groove 32. This design ensures that when the sliding part 122 extends into the groove 32, it creates a certain interference fit within the groove 32, thereby increasing the connection stability between the first baffle 12 and the second baffle 3. Simultaneously, since the sliding part 122 is located on both sides of the second baffle 3, this design also helps prevent the first baffle 12 from wobbling left and right within the groove 32, further enhancing the overall stability of the latch.

[0047] In a preferred embodiment, the latch further includes a fixing block 2, on which a countersunk hole 21 and a second through groove 22 are provided. The second through groove 22 and the first through groove 31 are directly opposite each other, and the middle part of the bent portion 11 passes through the first through groove 31 and the second through groove 22 in sequence.

[0048] Furthermore, the countersunk hole 21 and the through hole 33 are aligned, and the first threaded post sequentially passes through the countersunk hole 21, the through hole 33, and the adjusting threaded hole. The countersunk hole 21 forms a limit on the end of the first threaded post. Since the positions of the fixing block 2 and the second baffle 3 are relatively fixed, the end of the first threaded post is restricted by the countersunk hole 21 during the engagement of the first threaded post with the adjusting threaded hole, thereby preventing the first threaded post from being over-screwed or loosened.

[0049] Furthermore, the latch also includes a second screw post 4, which is sequentially threaded to the first fixing threaded hole 23 on the fixing block 2 and the second fixing threaded hole 34 on the second baffle 3.

[0050] Thus, the fixing block 2 and the second baffle 3 are fixed, and the countersunk hole 21 limits the end of the first screw post 5. Since the first screw post 5 is threadedly connected to the adjusting threaded hole, rotating the first screw post 5 will cause the distance between the first baffle 12 and the second baffle 3 to change. Meanwhile, the positions of the fixing block 2 and the second baffle 3 are relatively fixed. At this time, the position of the retaining ring 1 is changed, thereby changing the area of ​​the insertion space, and finally adjusting the locking position and locking force.

[0051] It is worth noting that the first screw post 5 and the second screw post 4 are arranged in parallel. For example... Figure 2As shown, the first screw post 5 and the second screw post 4 are located on both sides of the latch. This parallel arrangement not only enhances the overall stability of the latch, but also allows the latch to better distribute stress when subjected to force, preventing damage caused by excessive force at a single point.

[0052] It should be noted that the direction in which the slide 32 extends is consistent with the direction in which the spring 6 extends and retracts.

[0053] Specifically, the slide groove 32 is formed on one side of the second baffle 3, and its extension direction follows the extension path of the spring 6. When the spring 6 is in a compressed state, the spring 6 applies an outward thrust to the latch, and the direction of this thrust matches the extension direction of the slide groove 32. Therefore, when the first screw post 5 rotates, the latch will move smoothly along the slide groove 32 under the thrust of the spring 6.

[0054] like Figures 4-5 As shown, a lock is provided, including the aforementioned latch, a locking pin 7, and a driving device 8, wherein the driving device 8 drives the locking pin 7 to pass through or disengage from the insertion space.

[0055] The locking pin 7 is a slender, cylindrical component designed to penetrate or disengage from the socket space of the retaining ring 1 under the drive of the drive device 8. The diameter of the locking pin 7 is carefully designed to ensure that it can be tightly inserted into the socket space, thereby providing a reliable locking effect.

[0056] The driving device 8 is a mechanism capable of generating linear or rotary motion to drive the movement of the locking pin 7. In this embodiment, the driving device 8 can be an electric motor, a pneumatic device, or a manually operated mechanism, depending on the application scenario and user requirements of the lock. The driving device 8 is connected to the locking pin 7 via a connector, such as a linkage or gear. When the driving device 8 is activated, it pushes or pulls the locking pin 7, causing it to pass through or disengage from the insertion space.

[0057] In actual operation, when a user needs to lock an object, the drive device 8 is activated, pushing the locking pin 7 through the slot space of the latch ring 1. Due to the tight fit between the locking pin 7 and the slot space, the lock is locked. When it is necessary to release the lock, the drive device 8 is activated again, but this time it pulls the locking pin 7, causing it to disengage from the slot space, thereby unlocking the lock.

[0058] Preferably, the drive device 8 includes a connector and a turntable. The connector connects the door handle and the turntable. When in use, the user twists the door handle to cause the turntable to rotate, which in turn drives the locking pin 7 connected to the edge of the turntable to move, so as to realize the locking and unlocking functions.

[0059] Specifically, the door handle is a component that a user can grip and twist. The turntable is a circular or nearly circular component, with its central part connected to the door handle via a connector, and its edge connected to the lock pin 7 via connectors. The connector can be a linkage, which is coaxial with both the door handle and the turntable, with its two ends connected to the door handle and the turntable, respectively.

[0060] In practice, when a user needs to lock an object, they grasp the door handle and turn it clockwise or counterclockwise, depending on the lock's design. This causes the turntable to rotate. The locking pin 7, connected to the edge of the turntable, moves with the turntable, gradually approaching and eventually penetrating the slot of the latch ring 1. Due to the tight fit between the locking pin 7 and the slot, the object is securely locked within the latch.

[0061] When the user needs to unlock the object, they grasp the door handle again and twist it in the opposite direction, which will cause the dial to rotate in the opposite direction. As the dial rotates, the locking pin 7 on the edge of the dial gradually disengages from the socket space, thereby releasing the object.

[0062] To ensure the reliability and security of the lock, we have also designed a variety of safety mechanisms. For example, a limiting mechanism can be set between the turntable and the locking pin 7 to prevent the locking pin 7 from moving excessively during locking or unlocking. In addition, a return spring 6 can be set between the door handle and the turntable so that the turntable can automatically return to its initial position after the user releases the door handle.

[0063] like Figure 6 A box structure includes the above-mentioned lock, and also includes a box door 10 and a box body, with a latch installed on the box body, and a locking pin 7 and a driving device 8 installed on the box door 10.

[0064] Furthermore, the housing includes a locking mounting plate 9, which is fixedly connected to the second baffle 3.

[0065] Specifically, the fixing plate and the second baffle 3 are located on both sides of the locking mounting plate 9. The fixing plate and the second baffle 3 clamp the locking mounting plate 9, and the second screw post 4 fastens the fixing plate and the second baffle 3 to achieve stable clamping of the locking mounting plate 9 by the fixing plate and the second baffle 3. More preferably, the second screw post 4 connects the fixing plate, the locking mounting plate 9 and the second baffle 3 in sequence to achieve stable connection of the fixing plate, the locking mounting plate 9 and the second baffle 3, thereby fixing the position of the fixing plate and the second baffle 3.

[0066] The case is a structure with internal space for storing items. An opening is provided on one side or end face of the case to allow the user to access the items inside. To close this opening, a door 10 is fitted. The door 10 is a panel that can be opened and closed, and its size and shape match the opening of the case. When the door 10 is closed, it fits tightly against the opening of the case to prevent items from being lost or damaged.

[0067] The latch is installed on the edge of the opening of the enclosure, specifically through the latch mounting plate 9. The enclosure includes the latch mounting plate 9, which is used to securely fix the latch to the enclosure. The latch mounting plate 9 is connected to the edge of the opening of the enclosure, which can be achieved by welding, bolting, or other fixing methods.

[0068] The fixing plate and the second baffle 3 are respectively located on both sides of the latch mounting plate 9, and together they clamp the latch mounting plate 9 to ensure stable installation of the latch. To enhance this clamping effect, a second screw post 4 is used to fasten the fixing plate and the second baffle 3. The second screw post 4 passes through corresponding holes on the fixing plate, the latch mounting plate 9, and the second baffle 3 in sequence, and is firmly fixed together by a threaded connection. This design not only achieves stable clamping of the latch mounting plate 9 by the fixing plate and the second baffle 3, but also ensures the fixed position of the fixing plate and the second baffle 3, thereby improving the stability and reliability of the entire lock structure.

[0069] Locking pin 7 and drive mechanism 8 are mounted on the door 10. Locking pin 7 is connected to drive mechanism 8. When a user needs to open the door 10, they operate drive mechanism 8, such as by turning the door handle, which causes drive mechanism 8 to move locking pin 7. Locking pin 7 gradually disengages from the latch's slot, thereby releasing the door 10 and allowing it to be opened. When a user needs to close the door 10, they push the door 10 back to the closed position and operate drive mechanism 8 to re-enter the latch's slot, thereby locking the door 10.

[0070] By introducing a combination of a fixing plate and a second baffle 3, and using a second screw post 4 to securely fasten them to the latch mounting plate 9, we have significantly enhanced the stability and reliability of the lock structure. This design makes the latch more stable during installation and use, and less susceptible to external interference or damage.

[0071] The mounting positions of the locking pin 7 and the drive unit 8 allow users to easily operate the lock, completing locking and unlocking operations without additional tools or force. This greatly improves the ease of use of the lock's structure.

[0072] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
