Description

Technical Field

[0001] This utility model relates to the field of computer hardware technology, and in particular to a locking device and a server cover. Background Technology

[0002] With the development of information technology, servers, as the core equipment of data centers, require increasingly frequent maintenance and upgrades. When replacing or maintaining internal server components, it is usually necessary to first remove the cover covering the front or side panels. To ensure security and prevent unauthorized access, most servers are equipped with specially designed cover locking mechanisms. These mechanisms typically use mechanical pins combined with compression springs to achieve locking and unlocking functions.

[0003] However, such locking devices in the prior art have some obvious shortcomings:

[0004] Difficult to operate: Due to the limited range of spring force, users need to precisely control the applied force when opening or closing the latch. If the force is too great, the pin may not be able to spring back properly; conversely, if the force is too small, the pin may not extend fully, causing the mask to loosen or even fall off.

[0005] Potential for damage: After repeated use, the spring may gradually lose its original elasticity, affecting the locking performance. Furthermore, without proper guide structure support during the extension and retraction of the latch, it is prone to misalignment, potentially scratching the server casing or other sensitive components.

[0006] Short lifespan: The above-mentioned problems not only affect the user experience, but also shorten the lifespan of the entire mask system and increase maintenance costs.

[0007] In view of the above shortcomings, it is necessary to develop a new type of locking device and server cover to overcome these problems and improve overall usability. Utility Model Content

[0008] In order to solve the problems existing in the prior art, this utility model proposes an improved locking device and a corresponding server cover.

[0009] The locking device includes a movable plate, a lock sleeve, a lock cylinder, a bolt, a spring, and a sliding switch. The sliding switch is fixedly connected to the movable plate. A pin is installed on the movable plate, and a through hole parallel to the pin is designed on the movable plate. The movable plate is slidably mounted on a guide post through the through hole, and a spring is designed on the guide post to abut against the movable plate. The lock cylinder is installed inside the lock sleeve, and a bolt is installed at one end of the lock cylinder. A locking bar is designed on the bolt. When the lock cylinder rotates, it drives the locking bar to rotate, thereby restricting or releasing the movable plate and the bolt.

[0010] More preferably, one end of the lock cylinder is designed with a groove, requiring a key that matches the groove to rotate the lock cylinder. The other end of the lock cylinder is designed with a lever, and the bolt is designed with a guide hole that matches the lever. When the lock cylinder rotates, the lever drives the bolt's locking bar to rotate.

[0011] Further description of the aforementioned solution: the outer surface of the lock cylinder is designed with threads and is fitted with a nut to facilitate fixing the lock body to the faceplate.

[0012] More preferably, at least two guide posts are provided, and the spring is sleeved on the guide posts and pushes the movable plate to limit the spring from deviating from its center during movement.

[0013] This utility model also discloses a server face shield, which adopts the aforementioned locking device and includes a face shield body. The guide post is fixedly installed on the inner side of one end of the face shield body, and the pin protrudes from one end of the face shield body under the elastic force of a spring. The sliding switch is located on the outer side of the face shield body and is fixedly connected to the movable plate. The locking sleeve is fixed to the face shield body by a nut and is located on one side of the movable plate. When the lock cylinder is rotated on the outer side of the face shield body, the lock cylinder drives the locking strip to rotate, thereby restricting or releasing the movable plate and the pin.

[0014] Further description of the aforementioned solution: a locking pin protruding from the end of the mask body is installed at one end relative to the guide post, in order to cooperate with the pin to fix the mask body to the server.

[0015] Optionally, the mask body is square and has a hollow design.

[0016] Compared with the prior art, the locking device proposed in this utility model has the following significant advantages over traditional designs:

[0017] Improved ease of operation: The new design uses guide posts to guide the movement path of the spring and pin, making the opening and closing process smoother and more controllable. Users do not need to worry about operational difficulties caused by uneven force application.

[0018] Enhanced durability: By effectively constraining the movement trajectory of the pin, uneven pressure distribution on the spring is reduced, helping to keep the spring in good working condition for a long time. It also avoids wear caused by unstable pin movement.

[0019] Reduce accidental injuries: The carefully designed slide system can maintain the relative positional relationship between the components, ensuring that there will be no collisions or scratches even during rapid disassembly and assembly.

[0020] Adaptable to various application scenarios: Thanks to its flexible and adjustable design concept, this type of locking device is not limited to server covers, but can also be widely used in other equipment that requires opening and closing covers.

[0021] The server shield proposed in this invention has the following significant advantages over traditional designs:

[0022] Improved ease of use: Thanks to the improved locking mechanism, the mask can be removed and installed more easily and quickly, reducing the time and difficulty for maintenance personnel.

[0023] The sliding switch is located on the outside of the mask body, making operation more intuitive and improving the user experience.

[0024] The combination of the lock cylinder and the locking strip enhances the security of the mask, ensuring that it can only be unlocked with the correct key, effectively preventing unauthorized access.

[0025] Enhanced heat dissipation: The square shape and hollow design of the faceplate provide excellent heat dissipation, helping to maintain stable internal server temperatures, extend server lifespan, and enhance the aesthetics of the faceplate, meeting the requirements of modern data centers for equipment appearance.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0038] Example 1

[0039] This embodiment discloses a locking device, such as... Figures 1 to 3 As shown, the lock assembly includes a movable plate 1, a lock sleeve 43, a lock cylinder 4, a bolt 5, a spring 3, and a sliding switch 2. The sliding switch 2 is fixedly connected to the movable plate 1. A pin 11 is installed on the movable plate 1, and a through hole parallel to the pin 11 is designed on the movable plate 1. The movable plate 1 is slidably mounted on a guide post 12 through the through hole, and a spring 3 is designed on the guide post 12 to abut against the movable plate 1. The lock cylinder 4 is installed inside the lock sleeve 43. A bolt 5 is installed at one end of the lock cylinder 4, and a retaining strip 51 is designed on the bolt 5. When the lock cylinder 4 rotates, it drives the retaining strip 51 to rotate, thereby restricting or releasing the movable plate 1 and the pin 11. A groove 42 is designed at one end of the lock cylinder 4, requiring a key that matches the groove 42 to rotate the lock cylinder 4. A lever 41 is designed at the other end of the lock cylinder 4, and a guide hole 52 that matches the lever 41 is designed on the bolt 5. When the lock cylinder 4 rotates, the lever 41 drives the retaining strip 51 of the bolt 5 to rotate.

[0040] In this embodiment, the outer surface of the lock cylinder 4 is designed with threads and is fitted with a nut 7 to facilitate fixing the lock body to the mask body 8.

[0041] In this embodiment, two guide posts 12 are provided, and the spring 3 is sleeved on the guide posts 12 and pushes the movable plate 1 to limit the spring 3 from deviating from its concentricity during the movement.

[0042] Example 2

[0043] This utility model also discloses a server cover, which adopts the locking device of Embodiment 1, such as... Figures 4 to 8 As shown, the server also includes a face mask body 8, a guide post 12 fixedly installed on the inner side of one end of the face mask body 8, a pin 11 protruding from one end of the face mask body 8 under the elastic force of the spring 3, a sliding switch 2 located on the outer side of the face mask body 8 and fixedly connected to the movable plate 1; a locking sleeve 43 is fixed to the face mask body 8 by a nut 7 and located on one side of the movable plate 1. When the lock cylinder 4 is rotated on the outer side of the face mask body 8, the lock cylinder 4 drives the locking strip 51 to rotate, thereby restricting or releasing the movable plate 1 and the pin 11. Figure 8 As shown, a locking post protruding from the end of the mask body 8 is also installed on one side of the guide post 12 to cooperate with the pin 11 to fix the mask body 8 to the server. In this embodiment, the mask body 8 is square and adopts a hollow design. In other embodiments, different shapes and different hollow textures can be adopted.

[0044] To gain a more thorough and comprehensive understanding of the disclosure of this utility model, its principles will be further explained below in conjunction with its usage.

[0045] like Figures 4 to 8 As shown, when installing the locking device on the mask body 8, at least two guide posts 12 need to be installed on the inner side of one end of the mask body 8, and a through hole for the pin 11 to pass through is opened at the end of the mask body 8. The movable plate 1 is fitted onto the guide post 12, allowing the movable plate 1 to move on the guide post 12. At the same time, the pin 11 moves within the through hole, achieving the directional installation of the movable plate 1. Next, a spring 3 is installed on the guide post 12, and the elastic force of the spring 3 abuts the movable plate 1 against the end of the mask body 8.

[0046] A sliding switch 2 is installed on the outside of the mask body 8, and the sliding switch 2 is connected to the movable plate 1 by screws 6. Then, the lock sleeve 43 with lock cylinder 4 and lock tongue 5 is fixed to the mask body 8 by nuts 7.

[0047] like Figure 5 As shown, when the lock cylinder 4 is rotated to the locked state by the key, the locking bar 51 of the lock tongue 5 abuts against the abutment part 13 of the movable plate 1. At this time, there is no response when the sliding switch 2 is turned, and the pin 11 cannot be retracted into the mask body 8. Therefore, the mask body 8 cannot be removed from the server, which effectively protects the server data security.

[0048] like Figure 6As shown, when the lock cylinder 4 is rotated to the unlocked state using the key, the locking bar 51 of the bolt 5 rotates to the other side. At this time, the sliding switch 2 is activated, which drives the movable plate 1 and the pin 11, allowing the mask body 8 to be removed from the server.

[0049] The movable plate 1 adopts the directional design of guide post 12 and pin 11, and with the vertical positioning of sliding switch 2, it effectively ensures the stability and reliability of movable plate 1 during use.
