Description

Technical Field

[0001] This utility model relates to the field of electronic equipment manufacturing technology, specifically to a snap-fit ​​structure for a layered flow-guiding shield. Background Technology

[0002] With the rapid development of electronic information technology, electronic devices are evolving towards miniaturization, integration, and high frequency, making the requirements for electromagnetic shielding and thermal management performance increasingly stringent.

[0003] Currently, the upper and lower layers of the layered shielding cover are mostly connected by screw fastening or welding. Although screw fastening can provide a certain connection strength, the installation and disassembly process is cumbersome, requiring the use of tools such as screwdrivers, which consumes a lot of time and labor costs. Frequent disassembly and assembly can easily lead to thread wear, affecting the reliability of the connection and failing to meet the high-efficiency assembly requirements of automated production lines. Although welding can achieve a stable connection, it is a permanent connection. Once welded, it is difficult to disassemble, which greatly increases the difficulty of later equipment debugging, maintenance and component replacement. If repair is required, there may be a risk of damaging the overall structure. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a snap-fit ​​structure for a layered flow-guiding shield, which solves the problems of inconvenient installation and disassembly, unstable structure, and poor heat dissipation and shielding performance of traditional layered flow-guiding shields.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a snap-fit ​​structure for a layered flow-guiding shield, comprising: a lower shield and an upper shield. The top of the lower shield contacts the outer wall of the upper shield. A quick-release device is fixedly connected to the inner wall of the lower shield. The quick-release device uses elasticity for locking. The quick-release device includes four positioning posts. A compression spring is fixedly connected to the inner wall of each positioning post via a sliding groove. The sliding groove is located on the inner wall of the positioning post. The four positioning posts in the quick-release device, in conjunction with the sliding groove on the inner wall of the upper shield, can quickly guide the upper shield and the lower shield to align accurately during installation, avoiding misalignment and greatly improving assembly efficiency.

[0008] Preferably, the outer wall of the positioning post is fixedly connected to the inner wall of the lower shielding cover, and the outer wall of the positioning post is slidably connected to the inner wall of the upper shielding cover through a sliding groove. The sliding groove is opened on the inner wall of the upper shielding cover. The sliding cooperation between the positioning post and the sliding groove makes the installation process smoother and reduces the difficulty and time cost of manual operation.

[0009] Preferably, a slide rod is fixedly connected to the end of the compression spring away from the positioning post, and a limit ring is slidably connected to the outer wall of the slide rod. Utilizing the elasticity of the compression spring, when the upper shield is installed downwards, the inclined area of ​​the slider contacts and is compressed with the outer wall of the upper shield, and the compression spring contracts to make the slider slide into the positioning post.

[0010] Preferably, the outer wall of the slide rod is slidably connected to the inner wall of the positioning post, and the outer wall of the limiting ring is fixedly connected to the inner wall of the positioning post.

[0011] Preferably, a slider is fixedly connected to the end of the slide rod away from the compression spring. The top of the slider has a sloping area, and the outer wall of the slider is slidably connected to an unlocking groove. By setting the unlocking groove, when it is necessary to disassemble the upper shielding cover for equipment debugging, component replacement, or other maintenance operations, it is only necessary to use a tool to reach into the unlocking groove and push the slider to overcome the elastic force of the compression spring and slide it into the positioning post, thereby releasing the jamming state between the slider and the upper shielding cover and easily removing the upper shielding cover.

[0012] Preferably, the outer wall of the slider is slidably connected to the inner wall of the positioning post, the outer wall of the inclined area is slidably connected to the outer wall of the upper shield, and the unlocking groove is formed in the wall of the upper shield.

[0013] Beneficial effects

[0014] This invention provides a snap-fit ​​structure for a layered flow-guiding shield. It has the following advantages:

[0015] This utility model, by setting four positioning posts in the quick-installation device, can quickly guide the upper and lower shielding covers to accurately align during installation. The sliding cooperation between the positioning posts and the slide groove makes the installation process smoother. Utilizing the elasticity of the compression spring, the inclined area of ​​the slider contacts and is pressed against the outer wall of the upper shielding cover. The compression spring contracts, causing the slider to slide inward into the positioning post, locking into the upper shielding cover and achieving elastic locking. This connection method can provide a stable and reliable mechanical fixing force, ensuring that the upper and lower shielding covers will not loosen or separate due to vibration, external forces, or other factors during equipment operation. By setting an unlocking groove, simply use a tool to push the slider into the unlocking groove, causing it to overcome the elasticity of the compression spring and slide inward into the positioning post, thus releasing the locking state between the slider and the upper shielding cover, and easily removing the upper shielding cover.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] Please see Figure 1-4 This utility model provides a technical solution: a snap-fit ​​structure for a layered flow-guiding shield, comprising:

[0024] The lower shield 1 and the upper shield 2 are connected. The top of the lower shield 1 is in contact with the outer wall of the upper shield 2. The inner wall of the lower shield 1 is fixedly connected with a quick-release device 3. The quick-release device 3 uses elasticity to lock. The lower shield 1, the upper shield 2 and the quick-release device 3 are combined. The quick-release device 3 uses elasticity to quickly fix the lower shield 1 and the upper shield 2.

[0025] The quick-installation device 3 includes four positioning posts 30. The inner wall of the positioning post 30 is fixedly connected to the compression spring 31 through a sliding groove, and the sliding groove is opened on the inner wall of the positioning post 30. The outer wall of the positioning post 30 is fixedly connected to the inner wall of the lower shield 1. The outer wall of the positioning post 30 is slidably connected to the inner wall of the upper shield 2 through a sliding groove, and the sliding groove is opened on the inner wall of the upper shield 2. When installing the upper and lower shields 1, the outer wall of the positioning post 30 is fixedly connected to the inner wall of the lower shield 1. The sliding groove opened on the outer wall of the positioning post 30 and the inner wall of the upper shield 2 cooperate with each other, which can quickly and accurately guide the upper shield 2 and the lower shield 1 to align, avoid misalignment, and significantly improve assembly efficiency.

[0026] A slide rod 32 is fixedly connected to the end of the compression spring 31 away from the positioning post 30. A limit ring 33 is slidably connected to the outer wall of the slide rod 32. The outer wall of the slide rod 32 is slidably connected to the inner wall of the positioning post 30. The outer wall of the limit ring 33 is fixedly connected to the inner wall of the positioning post 30. When the upper shield 2 slides down along the positioning post 30, the top of the inclined area 35 is slidably connected to the outer wall of the upper shield 2, and the inclined area 35 at the top of the slider 34 contacts the outer wall of the upper shield 2. As the upper shield 2 continues to move down, the inclined area 35 is compressed, causing the slider 34 to overcome the elastic force of the compression spring 31 and drive the slide rod 32 into the positioning post 30. When the slider 34 moves to a specific position aligned with the unlocking groove 36 in the wall of the upper shield 2, the elastic potential energy of the compression spring 31 is released, pushing the slider 34 to reset and pop out. The slider 34 is precisely locked into the unlocking groove 36, thereby achieving elastic locking of the upper and lower shields 1. This locking method based on the elasticity of the compression spring 31 can provide a stable and reliable mechanical fixing force for the upper and lower shields 1. Even if the equipment is subjected to vibration, external impact or other situations during operation, the upper and lower shields 1 will not easily loosen or separate, effectively ensuring the stability of the overall structure of the shield.

[0027] A slider 34 is fixedly connected to the end of the slide rod 32 away from the compression spring 31. A sloped area 35 is formed at the top of the slider 34. An unlocking groove 36 is slidably connected to the outer wall of the slider 34. The outer wall of the slider 34 is slidably connected to the inner wall of the positioning post 30. The outer wall of the sloped area 35 is slidably connected to the outer wall of the upper shield 2. The unlocking groove 36 is located within the wall of the upper shield 2. When the equipment needs to be replaced, a tool such as a thin rod is inserted into the unlocking groove 36 to apply external force to the slider 34. Under this external force, the slider 34... 4. Overcoming the elastic force of the compression spring 31, the slide rod 32 is driven to slide into the positioning post 30 again. The slider 34 disengages from the unlocking groove 36, releasing the snap-fit ​​state with the upper shield 2. Due to the constraint of the limiting ring 33, the slide rod 32 is prevented from popping out of the positioning post 30. At this time, the upper shield 2 loses the snap-fit ​​constraint and can be easily removed, thereby maintaining the equipment inside the shield. This disassembly method does not require complicated tools, is simple and convenient to operate, greatly reduces the maintenance difficulty, and shortens the maintenance time.

[0028] In use, it consists of a lower shield 1, an upper shield 2 and a quick-release device 3. The quick-release device 3 uses elasticity to quickly fix the lower shield 1 and the upper shield 2.

[0029] During the installation of the upper and lower shielding covers 1, the outer wall of the positioning post 30 is fixedly connected to the inner wall of the lower shielding cover 1, and its outer wall cooperates with the sliding groove opened on the inner wall of the upper shielding cover 2. This can quickly and accurately guide the upper shielding cover 2 and the lower shielding cover 1 to align, avoid misalignment, and significantly improve assembly efficiency.

[0030] As the upper shield 2 slides down along the positioning post 30, the top of the inclined area 35 slides and connects with the outer wall of the upper shield 2. The inclined area 35 at the top of the slider 34 contacts the outer wall of the upper shield 2. As the upper shield 2 continues to move down, the inclined area 35 is compressed, causing the slider 34 to overcome the elastic force of the compression spring 31 and drive the slide rod 32 to slide into the positioning post 30. The compression spring 31 is compressed. When the slider 34 moves to a specific position aligned with the unlocking groove 36 in the wall of the upper shield 2, the elastic potential energy of the compression spring 31 is released, pushing the slider 34 to reset and pop out. The slider 34 is precisely locked into the unlocking groove 36, thereby achieving elastic locking of the upper and lower shields 1. This locking method based on the elasticity of the compression spring 31 can provide a stable and reliable mechanical fixing force for the upper and lower shields 1. Even if the equipment is subjected to vibration, external impact, etc. during operation, the upper and lower shields 1 will not easily loosen or separate, effectively ensuring the stability of the overall structure of the shield.

[0031] When equipment needs to be replaced, a tool such as a thin rod is inserted into the unlocking slot 36 to apply external force to the slider 34. Under the action of this external force, the slider 34 overcomes the elastic force of the compression spring 31 and drives the slide rod 32 to slide into the positioning post 30 again. The slider 34 disengages from the unlocking slot 36 and releases the locking state with the upper shield 2. Due to the constraint of the limiting ring 33, the slide rod 32 is prevented from popping out of the positioning post 30. At this time, the upper shield 2 loses the locking constraint and can be easily removed, thereby maintaining the equipment inside the shield. This disassembly method does not require complicated tools, is simple and convenient to operate, greatly reduces the maintenance difficulty, and shortens the maintenance time.
