Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically to a quick-release structure for heat dissipation of a rain cover. Background Technology

[0002] In applications such as industrial automation, outdoor communication base stations, and new energy equipment, rain covers are key components for equipment protection and must combine waterproofing, dustproofing, and efficient heat dissipation in harsh environments.

[0003] Currently, traditional rain covers mostly use bolts and nuts to fix the heat dissipation components. Disassembly requires tools such as wrenches and screwdrivers, making the operation process cumbersome and time-consuming. Frequent disassembly and assembly can also lead to thread wear, reduce connection reliability, and increase maintenance costs. In addition, this type of fixed structure makes it difficult to quickly replace and modularly upgrade the heat dissipation components, and cannot adapt to the heat dissipation requirements under different operating conditions. For example, in high-temperature or high-dust environments, it is impossible to clean the blocked heat dissipation holes or replace them with high-performance heat dissipation modules in a timely manner, further exacerbating the risk of equipment operation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a quick-release structure for heat dissipation of a rain cover, which solves the problems of low heat dissipation efficiency, cumbersome disassembly and maintenance, poor structural reliability, and difficulty in adapting to different working conditions of traditional rain covers.

[0006] (II) Technical Solution

[0008] Preferably, the outer wall of the heat sink is slidably connected to the inner wall of the cover, the outer wall of the heat sink is in contact with the outer wall of the push plate, and the end of the compression spring away from the push plate is fixedly connected to the inner wall of the cover.

[0009] Preferably, the fixing device includes a turntable, with a pull rod symmetrically rotatably connected to the outer wall of the turntable, a linkage rod rotatably connected to the inner wall of the pull rod, and a ball fixedly connected to the outer wall of the linkage rod. The outer wall of the ball is arranged in a linear array along the outer wall of the linkage rod. In this invention, the turntable rotates to drive the pull rod and linkage rod to move, causing the ball to slide along the inner wall groove of the heat sink, thereby realizing the rapid unlocking and locking of the heat sink device.

[0013] Beneficial effects

[0014] This invention provides a quick-release structure for heat dissipation and drainage of a rain cover. It offers the following advantages:

[0015] This utility model, through the combination of a heat dissipation device and a fixing device, allows the user to rotate the turntable with one hand, causing the lever to move the linkage rod, which in turn causes the ball to slide along a pre-set groove on the inner wall of the heat dissipation plate. When the ball is embedded in a groove at a specific position, the heat dissipation device is locked. Rotating the turntable in the opposite direction causes the ball to disengage from the groove, thus quickly unlocking the device. At the same time, compression springs are arranged in a linear array along the outer wall of the push plate, continuously providing stable elastic support force to ensure that the heat dissipation plate is always tightly fitted to the inner wall of the cover, ensuring airtightness. The linear array design of the ball along the outer wall of the linkage rod ensures that the locking force is evenly distributed on the surface of the heat dissipation plate, effectively avoiding local stress concentration and improving the stability and reliability of the overall structure.

[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 quick-release structure for heat dissipation of a rain cover, comprising:

[0024] The cover 1 has a heat dissipation device 2 slidably connected to its inner wall and a fixing device 3 slidably connected to its outer wall. The fixing device 3 unlocks the heat dissipation device 2 by rotating it, allowing the heat dissipation device 2 to slide along the inner wall of the cover 1 and be fixed by the fixing device 3.

[0025] The heat dissipation device 2 includes a heat dissipation plate 20. A push plate 21 is provided on the outer wall of the heat dissipation plate 20. A compression spring 22 is symmetrically fixedly connected to the end of the push plate 21 away from the heat dissipation plate 20. The compression spring 22 is arranged in a linear array along the outer wall of the push plate 21. The outer wall of the heat dissipation plate 20 is symmetrically slidably connected to the outer wall of the fixing device 3. The outer wall of the heat dissipation plate 20 is slidably connected to the inner wall of the cover 1. The outer wall of the heat dissipation plate 20 is in contact with the outer wall of the push plate 21. The end of the compression spring 22 away from the push plate 21 is fixedly connected to the inner wall of the cover 1. During installation, since the outer wall of the heat dissipation device 2 is slidably connected to the inner wall of the cover 1, the heat dissipation device 2 is pushed into the predetermined position along the slide rail of the inner wall of the cover 1. At this time, the outer wall of the heat dissipation plate 20 is in contact with the push plate 21. The compression spring 22 is compressed and accumulates elastic potential energy, so that the heat dissipation plate 20 fits tightly against the inner wall of the cover 1, which ensures both sealing and enhances heat conduction.

[0026] The fixing device 3 includes a turntable 30. A pull rod 31 is symmetrically rotatably connected to the outer wall of the turntable 30. A linkage rod 32 is rotatably connected to the inner wall of the pull rod 31. A ball 33 is fixedly connected to the outer wall of the linkage rod 32. The outer walls of the balls 33 are arranged in a linear array along the outer wall of the linkage rod 32. The outer wall of the turntable 30 is rotatably connected to the outer wall of the cover 1. The linkage rod 32 is slidably connected to the outer wall of the cover 1. The outer wall of the balls 33 is slidably connected to the inner wall of the cover 1 via a groove, and the groove is located on the inner wall of the cover 1. The outer wall of the balls 33 is slidably connected to the curved surface of the outer wall of the heat sink 20. Furthermore, it is slidably connected to the inner wall of the heat sink 20 through a sliding groove. The sliding groove is opened on the inner wall of the heat sink 20. Then, the turntable 30 is rotated. Since the outer wall of the turntable 30 is symmetrically connected to the right pull rod 31, the pull rod 31 on its outer wall drives the linkage rod 32 to slide in the sliding groove of the cover 1. Since the outer wall of the linkage rod 32 is fixedly connected to the ball 33, the ball 33 arranged in a linear array on the linkage rod 32 moves along the arc-shaped sliding groove on the inner wall of the heat sink 20. When the turntable 30 rotates to the set angle, the ball 33 is embedded in the locking groove of the heat sink 20, forming a locking structure with multiple points of uniform force.

[0027] The inner wall of the turntable 30 is slidably connected with a pin 34, and the outer wall of the pin 34 is slidably connected with a pin hole 35. The outer wall of the pin 34 is slidably connected to the inner wall of the cover 1, and the pin hole 35 is opened in the inner wall of the cover 1. At the same time, the pin 34 is inserted into the pin hole 35 in the inner wall of the cover 1 to complete the secondary locking and ensure the structural stability under working conditions such as vibration and wind pressure.

[0028] When in use, the heat dissipation device 2 is slid along the inner wall of the cover 1 and fixed by the fixing device 3;

[0029] During installation, since the outer wall of the heat dissipation device 2 is slidably connected to the inner wall of the cover 1, the heat dissipation device 2 is pushed into the predetermined position along the slide rail on the inner wall of the cover 1. At this time, the outer wall of the heat dissipation plate 20 is in contact with the push plate 21, the compression spring 22 is compressed and accumulates elastic potential energy, so that the heat dissipation plate 20 is tightly attached to the inner wall of the cover 1, which ensures both sealing and heat conduction.

[0030] Then, the turntable 30 is rotated. Since the outer wall of the turntable 30 is symmetrically connected to the right pull rod 31, the pull rod 31 on its outer wall drives the linkage rod 32 to slide in the groove of the cover 1. Since the outer wall of the linkage rod 32 is fixedly connected to the ball 33, the ball 33 arranged in a linear array on the linkage rod 32 moves along the arc-shaped groove on the inner wall of the heat sink 20. When the turntable 30 rotates to the set angle, the ball 33 is embedded in the locking groove of the heat sink 20, forming a locking structure with multiple points of uniform force.

[0031] At the same time, the pin 34 is inserted into the pin hole 35 on the inner wall of the cover 1 to complete the secondary locking and ensure the structural stability under working conditions such as vibration and wind pressure.

[0032] During maintenance, first pull out the pin 34 to release the secondary limit, then rotate the turntable 30 in the opposite direction. The ball 33 disengages from the locking groove along the arc-shaped slide. After losing the limiting effect of the ball 33, the compressed spring 22 releases its elastic potential energy, pushing the push plate 21 and the heat sink 20 outward. The user can then easily pull the heat sink 2 out of the cover 1, completing the disassembly process. The entire operation requires no tools and can be completed by one person in a short time.
