Description
Technical Field
[0001] This utility model relates to the field of medical device box technology, and in particular to a novel press-type lock for sterilization boxes. Background Technology
[0002] Existing sterilization boxes typically employ a locking structure to ensure a tight closure between the lid and the box body. For example, patent CN206295380U discloses a field surgical medical instrument box whose locking mechanism consists of a base plate, an upper locking plate, a lower locking plate, and a lower lever, installed via riveting or welding. This locking structure has the following drawbacks: it is complex, cumbersome to operate, and requires multiple steps to open and close; it relies on hinges and pins, which are prone to wear after long-term use, leading to lock failure; it requires high processing precision, and installation and removal require specialized tools or equipment, making maintenance inconvenient; and it has many friction points, easily causing wear and shortening the lifespan of the sterilization box. Therefore, an improved locking structure is needed to improve the opening method of small sterilization boxes and optimize their stability during transportation and sterilization. Utility Model Content
[0003] To address the problems of complex structures, cumbersome operation, and inconvenient installation and disassembly in existing locking mechanisms, this utility model provides a novel press-type locking mechanism for sterilization boxes. The press-type locking mechanism with built-in spring clips locks the box body and lid, has a simple structure, is easy to operate, eliminates long-term wear, and can be installed and removed without the need for machinery.
[0004] This utility model provides a novel press-type lock for a sterilization box. The sterilization box includes a box body and a lid. The press-type lock includes a lock body and a latch. The lock body is mounted on the box body and can rotate relative to the box body. One end of the latch is rotatably connected to the lock body and limited by an elastic element, while the other end cooperates with the lid to lock the lid to the box body. The built-in elastic element sets the latch on the lock body, allowing it to be pressed and deformed, and released to return to its original position, thereby completing the engagement, disengagement, and locking of the latch with the lid.
[0005] Furthermore, the box body has a mounting groove to accommodate a push-button lock, with the outer side of the lock body flush with the outer side of the box body. This embedded design not only reduces space usage and makes the instrument box more aesthetically pleasing, but also prevents accidental activation of the lock mechanism, thus improving safety.
[0006] Furthermore, a locking channel is provided at the bottom of the lock body, with post-shaped pins at both ends. A spring connecting the post-shaped pins is installed in the locking groove, and mounting holes that mate with the post-shaped pins are opened on both sides of the mounting groove. This makes the lock installation simple, allowing for installation and removal from the box without the need for machinery.
[0007] Furthermore, a limiting hole is provided in the middle of the lock body, and a limiting boss that matches the limiting hole is provided in the mounting groove. The cooperation between the limiting hole and the limiting boss can effectively prevent unnecessary rotation of the lock body during use, thereby enhancing the stability of the lock.
[0008] Furthermore, the bolt is rotatably connected to the lock body via a pin, and the elastic element is a Z-shaped spring, which vertically limits the bolt to the lock body. Pressing the bolt triggers the deformation of the spring, thereby achieving rapid separation or locking of the bolt from the cover.
[0009] Furthermore, the upper edge of the mounting groove is provided with a notch to accommodate the bolt, and a limiting block is provided at the upper end of the lock body. The limiting block abuts against the notch, so that a space is formed between the bolt and the notch for the bolt to be pressed down. Through the cooperation of the limiting block and the notch, the lock body is further fixed, and space is reserved for pressing the bolt.
[0010] Furthermore, the bolt tip is equipped with an upwardly bent hook, and the cover has a lock hole into which the hook can engage. In the locked state, the hook engages in the lock hole; to unlock, press the bolt to separate the hook from the lock hole.
[0011] Furthermore, the box body has an opening into which the lid can extend, and a groove is provided along the upper edge of the box body to accommodate the lid. A push-button latch is provided at the opening end of the box body. The lid is inserted from the opening end and fixed in the groove, and the latch structure completes the locking.
[0012] The beneficial effects of this utility model are as follows: This utility model provides a novel press-type lock for sterilization boxes. The press-type lock structure with a built-in spring ensures the lock's release and locking upon resetting. The lock tongue inserts into the lock hole of the lid for limiting movement, eliminating long-term friction and preventing failure caused by prolonged friction, thus extending the lifespan of the sterilization box. The overall structure of the lock is simple and easy to install, requiring no machinery for installation and removal. The lock adopts an embedded design, flush with the end face of the box, which not only improves the overall aesthetics but also enhances safety, effectively preventing accidental opening of the locking structure and affecting its use.

[0014] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0015] A sterilization box is used to hold medical devices and includes a box body 1 and a lid 2. The box body 1 and lid 2 are locked together by a locking mechanism. To simplify the locking structure and optimize the stability of the sterilization box during transportation and sterilization, a novel press-type locking mechanism for the sterilization box is designed, such as... Figure 1 As shown, the device includes a lock body 3 and a latch 4. The lock body 3 is mounted on the box body 1 and can rotate relative to the box body 1. One end of the latch 4 is rotatably connected to the lock body 3 and limited by an elastic element 5. The other end cooperates with the box cover 2 to lock the box cover 2 and the box body 1. Under the action of the elastic element 5, the latch 4 can rotate and reset around the lock body 3. After being pressed down, the latch 4 can be placed under the box cover 2. After resetting, it is inserted into the corresponding lock hole 21 on the box cover 2 to complete the locking. The latch 4 is inserted into the sterilization box cover 2 for limiting, eliminating long-term friction. The overall structure is simple, easy to open and close, and the built-in elastic element 5 ensures that the latch resets.
[0016] like Figure 2 and 3As shown, to improve the overall aesthetics, the box body 1 has an installation groove 11 for accommodating the push-button lock. The outer side of the lock body 3, placed in the installation groove 11, is flush with the outer side of the box body 1. After installation, the disinfection box has no protruding parts, which reduces the risk of accidental opening or damage to the lock structure due to external collisions, and improves the safety and stability of the locking mechanism.
[0017] like Figure 6 and 7 As shown, for ease of installation and removal, a locking channel 31 is provided at the bottom of the lock body 3. A columnar pin 32 is provided at both ends of the locking channel 31. A spring 33 connecting the two columnar pins 32 is provided inside the locking channel 31. Mounting holes 12 that mate with the columnar pins 32 are provided on both sides of the mounting groove 11. A stop block is provided at the tail end of the columnar pin 32, which is placed inside the locking channel 31. The stop block has a spherical head that extends out of the locking channel 31 to better engage with the mounting holes 12 for installation, or to be removed from the mounting holes 12 for disassembly.
[0018] like Figure 1 As shown, in order to initially position the lock body 3, a limiting hole 34 is provided in the middle of the lock body 3, and a limiting boss 13 that matches the limiting hole 34 is provided in the mounting groove 11. During the closing process of the cover 2, the lock body 3 is first flipped so that it fits onto the limiting boss 13 through the limiting hole 34. At this time, the entire lock body 3 is in a vertical state, and the bolt 4, which is perpendicular to the lock body 3, is in a horizontal state, which facilitates operation and cooperation with the lock hole 21 on the cover 2.
[0019] like Figure 8 and 9 As shown, to ensure the rapid reset of the latch 4, the latch 4 is rotatably connected to the lock body 3 via a pin 41. The elastic element 5 is a Z-shaped spring, and the latch 4 is vertically limited to the lock body 3 by the Z-shaped spring. To ensure connection and rebound stability, two Z-shaped springs are provided. The upper part of the lock body 3 has a first spring hole 51, and the connection part between the latch 4 and the lock body 3 has a second spring hole 52. One end of the Z-shaped spring passes through the first spring hole 51 and is fixed to the bottom of the latch 4, while the other end of the Z-shaped spring is fixed in the second spring hole 52. The elastic element 5 can be fixed by strong adhesive or welding depending on the lock buckle material.
[0020] like Figure 4 and 5As shown, to further position the lock body 3, a notch 14 is provided along the upper edge of the mounting groove 11 to accommodate the bolt 4. A limiting block 35 is provided at the upper end of the lock body 3, which abuts against the notch 14, creating a space between the bolt 4 and the notch 14 for the bolt 4 to be pressed down. When the lock body 3 is flipped so that the limiting hole 34 is fitted onto the limiting boss 13, the limiting block 35 at the upper part of the lock body 3 is precisely abutted against the notch 14, thereby effectively fixing the lock body 3. After fixing, there is still space between the bolt 4 of the latch and the notch 14 for the pressing operation of the bolt 4.
[0021] To facilitate cooperation with the lid 2, the end of the latch 4 is provided with an upwardly bent latch 42, and the lid 2 has a lock hole 21 for the latch 42 to be engaged. After being pressed, the latch 44, which returns to its original position under the action of the elastic element 5, is precisely placed into the lock hole 21 of the lid 2 and locked in place, providing good stability.
[0022] like Figure 2 and 3 As shown, to facilitate the installation of the lid 2, the box body 1 has an opening into which the lid 2 can be inserted. The upper edge of the box body 1 is provided with a sliding groove 15 to accommodate the lid 2. A push-button latch is provided at the opening end of the box body 1. In use, the push-button latch is pressed into the mounting groove 11, so that the columnar pin 32 at the bottom of the lock body 3 abuts into the mounting holes 12 on both sides of the mounting groove 11. Then, the lid 2 is horizontally placed into the sliding groove 15 from the opening end of the box body 1 to complete the closing. Then, the lock body 3 is flipped to a vertical position, and the latch 4 is pressed so that the locking hook 42 at its end abuts against the bottom of the lid 2. At this time, the pressing force on the latch 4 is released, and the locking hook 42 is reset under the action of the elastic element 5 and abuts into the corresponding locking hole 21 on the lid 2, thus completing the locking of the box body 1 and the lid 2.
[0023] The above description is illustrative only and not restrictive of this utility model. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the appended claims, and all such modifications, variations or equivalents will fall within the protection scope of this utility model.
