[0036] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0038] It should also be understood that the terms used in the present application specification are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the present application specification and the appended claims, the singular forms "a", "an" and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0039] It should be further understood that the term "and / or" as used in the present application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0040] Please refer to Figures 1 to 12 The present application discloses a lock catch device, which comprises a lock catch 1, a mounting groove 2 and a clamping groove 3. The lock catch 1 comprises a rotating part 11 and a clamping part 12, which are fixedly connected. The lock catch 1 is movably installed in the mounting groove 2. Rotating the rotating part 11 can make the clamping part 12 rotate into the clamping groove 3 from the mounting groove 2, or rotate into the mounting groove 2 from the clamping groove 3.

[0041] Specifically, the rotating part 11 is a part of the lock 1, designed as a structure that can rotate relative to a certain fixed point or axis. In this embodiment, the rotating part 11 is fixedly connected with the clamping part 12, meaning that they rotate as a whole. The clamping part 12 is another part of the lock 1, fixedly connected with the rotating part 11. The clamping part 12 is designed to match the profile of the clamping groove 3, so as to be able to clamp into the clamping groove 3 when rotated to a certain position. The mounting groove 2 is a fixed structure in the lock device, usually located on one of the two components that need to be connected by the lock 1. The shape and size of the mounting groove 2 match the lock 1 (including the rotating part 11 and the clamping part 12), allowing the lock 1 to rotate freely within the mounting groove 2, but limiting its movement in other directions. The clamping groove 3 is another key structure in the lock device, usually located on the other component adjacent or opposite to the mounting groove 2. The shape and size of the clamping groove 3 match the clamping part 12 of the lock 1, which can clamp into the clamping groove 3 when the lock 1 is rotated to a certain position, thereby achieving the fixed connection of the two components. Due to the fixed connection of the rotating part 11 and the clamping part 12, the overall structure of the lock 1 is more concise, reducing the number of parts and assembly complexity; and through a simple rotating action, the connection and disconnection of the lock 1 can be achieved, which is intuitive and easy to master, greatly improving the convenience of use.

[0042] Further, the operating principle of the lock device is as follows: when two components need to be connected, first put the lock 1 (including the rotating part 11 and the clamping part 12) into the mounting groove 2. Then, rotate the rotating part 11 to make the clamping part 12 rotate out of the mounting groove 2 and clamp into the adjacent clamping groove 3. In this way, the two components are firmly connected together. When disconnection is needed, simply rotate the rotating part 11 in the opposite direction to make the clamping part 12 rotate out of the clamping groove 3 and re-enter the mounting groove 2. At this time, the two components can be easily separated.

[0043] As shown in Figure 2 , the rotating part 11 is composed of a rotating shaft 111 and a rotating piece 112, which are respectively arranged on both sides of the clamping part 12 and fixedly connected with the clamping part 12.

[0044] Specifically, the rotating shaft 111 is a key component in the lock device, which provides the axis of rotation for the lock 1. The rotating shaft 111 is designed as a cylindrical or other suitable shape for rotation. The rotating part 112 is another part of the lock 1 connected with the rotating shaft 111, which is fixedly connected with the clamping part 12. The design of the rotating part 112 depends on the specific shape and functional requirements of the lock 1, which contains a hole or groove matching the rotating shaft 111, so as to pass through and fix the rotating shaft 111 therein. In this embodiment, the rotating shaft 111 and the rotating part 112 are respectively arranged on both sides of the clamping part 12 and are fixedly connected with the clamping part 12. This means that the clamping part 12 is clamped between the rotating shaft 111 and the rotating part 112, forming a stable overall structure, thereby helping to enhance the structural strength of the lock 1, enabling it to withstand greater external forces.

[0045] Specifically, in this embodiment, the rotating part 112 is a rotating rib, which is usually a strip structure with a specific shape and size designed to provide rotational motion in the mechanism. The rotating rib usually has good rotation performance, which can reduce friction and resistance, making the lock device more smooth and stable during rotation. In this embodiment, the rotating rib as the rotating part 112 is installed in the rotating hole or connected with the rotating shaft 111, so as to rotate when needed. The rotating rib is made of metal, plastic or other suitable materials, and its shape and size are determined according to specific application requirements. For example, it can have a flat, circular or other irregular shape to adapt to different installation space and motion requirements.

[0046] As shown in Figures 3-8 , the two sides of the installation groove 2 are respectively provided with a rotating groove 21 and a rotating hole, the rotating shaft 111 is movably installed in the rotating groove 21, and the rotating part 112 is installed in the rotating hole.

[0047] Specifically, the rotating groove 21 is usually designed as a long strip or arc shape to provide enough space for the rotating shaft 111 to rotate. The shape and size of the rotating groove 21 should match the cross section of the rotating shaft 111 to ensure that the rotating shaft 111 can rotate smoothly therein. The rotating hole is usually designed as a circular or other suitable shape and size for the rotating part 112. The position of the rotating hole should correspond to the rotating groove 21, so that when the rotating shaft 111 passes through the rotating groove 21, the rotating part 112 can be installed and fixed in the rotating hole. By movably installing the rotating shaft 111 in the rotating groove 21 and installing the rotating part 112 in the rotating hole, the lock 1 can maintain a smooth motion trajectory during rotation. This helps to reduce friction and wear, improving the service life of the lock 1.

[0048] As shown in Figures 3-8As shown, the end of the rotating shaft 111 away from the clamping portion 12 is provided with a limiting member 113, the rotating shaft 111 between the clamping portion 12 and the limiting member 113 is embedded in the rotating groove 21, and the limiting member 113 limits the movement of the rotating shaft 111.

[0049] Specifically, the limiting member 113 is a component fixed at the end of the rotating shaft 111. In this embodiment, the limiting member 113 is a shaft cap, which should match the shape and size of the end of the rotating groove 21, so that when the rotating shaft 111 rotates to a certain position, the limiting member 113 can abut against the end of the rotating groove 21, thereby limiting the further movement of the rotating shaft 111. The limiting member 113 can be fixed on the rotating shaft 111 by welding, threaded connection, pin connection, etc. The rotating shaft 111 is embedded in the rotating groove 21, which means that the cross-sectional shape and size of the rotating shaft 111 should match the shape and size of the rotating groove 21. In this way, the rotating shaft 111 can rotate smoothly in the rotating groove 21 without excessive friction or resistance. When the rotating shaft 111 rotates, the limiting member 113 will rotate with it, and the limiting member 113 abutting against the end of the rotating groove 21 will limit the further movement of the rotating shaft 111. This design can ensure that the limiting member 113 can be firmly retained at the end of the rotating shaft 111 during the rotation of the lock catch 1, and will not fall off or loosen.

[0050] As shown, Figures 3-8 the clamping portion 12 is a clamping plate, one side of the clamping portion 12 is provided with a limiting protrusion 121, and the mounting groove 2 is also provided with a limiting hole 22. When the clamping portion 12 is screwed into the mounting groove 2, the limiting protrusion 121 is engaged with the limiting hole 22.

[0051] Specifically, the limiting protrusion 121 is a structure protruding from the side of the clamping plate, which should match the shape and size of the limiting hole 22 on the mounting groove 2. The design of the limiting protrusion 121 can ensure that it can be smoothly engaged with the limiting hole 22 when the clamping plate is screwed into the mounting groove 2. By engaging the limiting protrusion 121 with the limiting hole 22, the lock catch device can maintain high stability during connection. This design prevents accidental movement or falling of the clamping plate in the mounting groove 2, thereby ensuring the reliability of the connection of the lock catch 1.

[0052] In an alternative embodiment, the rotating shaft 111 is a flexible rotating shaft.

[0053] Specifically, the design of the elastic rotating shaft allows the locking device to better adapt to different installation spaces and movement requirements. It can deform when subjected to external forces, thus adapting to different rotation angles and force requirements. Secondly, the design of the elastic rotating shaft helps to reduce wear and fatigue damage during rotation. It can deform and absorb energy when subjected to external forces, thus reducing the impact and wear on the rotating shaft 111 and related components. This helps to prolong the service life of the locking device and improve its reliability.

[0054] Please refer to Figures 1-12 Another specific embodiment of the utility model also discloses a cold fan, including fuselage 4, water tank 5 and the locking device of above-mentioned embodiment, locking device is built-in in fuselage 4, water tank 5 is located below fuselage 4.

[0055] Specifically, the fuselage 4 is the main part of the cold fan, which usually has one or more air inlets and outlets for air circulation and cooling. The fuselage 4 also contains key components such as fans, refrigeration elements (such as ice or refrigeration pieces) inside. The water tank 5 is used to store and supply cooling medium (such as water or ice water). The water tank 5 is usually located below the fuselage 4 so that the cooling medium can be easily added or replaced when needed. The shape, size and capacity of the water tank 5 may vary depending on the specific model and application requirements of the cold fan. In this embodiment, the water tank 5 is connected to the fuselage 4 through the locking device to ensure its stability and reliability. As in the above embodiment, the locking device includes rotating shaft 111, clamping part 12 (such as clamping plate), limiting convex point 121, mounting groove 2 and limiting hole 22 and other key components. These components work together to achieve quick and reliable connection and fixation between the water tank 5 and the fuselage 4. In this embodiment, the locking device is built-in in the fuselage 4, and users can easily fix or release the water tank 5 by operating the rotating part 112 (such as rotating rib) of the locking device. This design not only improves the ease of use of the cold fan, but also ensures its stability and safety.

[0056] As Figures 9 to 10 shown, the bottom of the fuselage 4 is provided with a fixed groove 41, and the water tank 5 is installed in the fixed groove 41.

[0057] Specifically, the bottom of the fuselage 4 of the cold fan is provided with a fixed groove 41. This fixed groove 41 is specially designed for the installation of the water tank 5, and its shape, size and depth are matched with the water tank 5 to ensure that the water tank 5 can be stably and firmly installed in the fixed groove 41.

[0058] As Figures 9-12 shown, the mounting groove 2 is located at the bottom of the fuselage 4, and the clamping groove 3 is located at the top of the water tank 5. The position of the mounting groove 2 corresponds to the position of the water tank 5.

[0059] Specifically, the top of the water tank 5 is designed with a clamping groove 3, which corresponds to the locking device in the mounting groove 2. The shape, size and position of the clamping groove 3 are determined according to the design of the locking device to ensure that they can perfectly match together. When the water tank 5 is placed on the body 4, the clamping groove 3 at the top of the water tank 5 will be in contact with the locking device, and the locking and unlocking of the water tank 5 will be completed through the rotation or movement of the locking device.

[0060] Further, the surface of the body 4 is provided with an indication mark. When the water tank 5 is in the locked state, the indication mark is a lock symbol, and when the water tank 5 is in the unlocked state, the indication mark is an unlock symbol.

[0061] Specifically, the surface of the body 4 (arranged at a position easily observed by the user) is designed with an indication mark area. This area can be presented by printing, carving, LED display or other means. The indication mark includes two symbols: a lock symbol and an unlock symbol. The lock symbol usually represents a closed lock or similar graphics, while the unlock symbol may represent an open lock, an arrow or other graphics indicating release or movement. The cold fan is internally provided with a state detection mechanism for detecting the locking or unlocking state of the water tank 5. This mechanism can be realized by sensors, switches or other detection means. When the water tank 5 is properly locked, the sensor will send a signal to the indication system; when the water tank 5 is unlocked or not properly locked, the sensor will send another signal. After receiving the signal, the indication system will display the corresponding symbol in the indication mark area according to the signal content. The user can intuitively understand the current state of the water tank 5 by observing the indication mark on the surface of the body 4. If the indication mark displays the lock symbol, the user knows that the water tank 5 has been locked and can safely use the cold fan. If the indication mark displays the unlock symbol, the user knows that the water tank 5 is not locked or has been unlocked, and needs to take appropriate action (such as relocking the water tank 5).

[0062] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
