Detailed Implementation
[0025] 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.
[0026] In practical implementation: such as Figure 1-7 As shown, an easy-to-assemble and use circuit board includes a housing 1 and a circuit board body 2: the circuit board body 2 is located inside the housing 1, a portable assembly mechanism 3 is provided on the side of the circuit board body 2, a support and protection mechanism 4 is provided on the side of the portable assembly mechanism 3, and an auxiliary cooling mechanism 5 is provided on the side of the support and protection mechanism 4.
[0027] The portable assembly mechanism 3 includes a positioning mounting plate 31, a square mounting groove 32, a liner 33, a positioning T-shaped strip 34, and a positioning T-shaped groove 35. The positioning mounting plate 31 is provided on the inner side wall of the housing 1 at the mounting position of the circuit board body 2. The square mounting groove 32 is provided on the outer side wall of the positioning mounting plate 31. The liner 33 is provided on the outer side wall of the circuit board body 2. The size of the liner 33 matches that of the square mounting groove 32. Positioning grooves are symmetrically provided on the outer walls of the liner 33 at the top position. The T-shaped strip 34 and the positioning mounting plate 31 are provided with corresponding positioning T-shaped grooves 35 on the inner walls of both sides of the square mounting groove 32. The positioning T-shaped strip 34 and the positioning T-shaped grooves 35 are slidably installed. The outer side wall of the positioning mounting plate 31 at the positioning T-shaped groove 35 is symmetrically provided with a first threaded groove 36. The outer side wall of the positioning T-shaped strip 34 is provided with two sets of second threaded grooves 37. The first threaded groove 36 and the second threaded groove 37 are threadedly installed with the fastening bolt 38.
[0028] When it is necessary to install the circuit board body 2 into the enclosure 1, refer to the instruction manual. Figure 3 As shown, at this time, the positioning mounting plate 31 needs to be installed on the inner wall of the enclosure 1 using the bolt mounting assembly according to the existing operating techniques. After the positioning mounting plate 31 is installed, the liner 33 only needs to be adjusted to a suitable position and the positioning T-shaped strip 34 on its side is pushed from top to bottom into the corresponding positioning T-shaped groove 35. When the positioning T-shaped strip 34 moves to the position where the second threaded groove 37 coincides with the first threaded groove 36, the fastening bolt 38 is used along the horizontal side to pass through the first threaded groove 36 and screwed to the bottom of the second threaded groove 37 to complete the positioning installation of the liner 33, and thus complete the installation of the circuit board body 2.
[0029] The support and protection mechanism 4 includes a positioning T-block 41 and a support spring 42. The positioning T-block 41 is slidably installed inside the positioning T-groove 35, and the support spring 42 is connected between the bottom outer wall of the positioning T-block 41 and the bottom inner wall of the positioning T-groove 35. Here, due to the sliding friction between the positioning T-block 41 and the positioning T-groove 35, combined with the buffering effect of the support spring 42, a simple damping structure is formed. When the positioning T-strip 34 is pushed into the positioning T-groove 35 too fast, the positioning T-block 41 can be displaced downward to squeeze the support spring 42 to achieve a buffering effect, thus preventing damage to the circuit board body 2 due to excessive insertion speed.
[0030] The overall height of the positioning T-shaped strip 34 and the positioning T-shaped block 41 is less than the depth of the positioning T-shaped groove 35; this design ensures that the installation process of the circuit board body 2 can be carried out smoothly.
[0031] The auxiliary cooling mechanism 5 includes a small axial flow fan 51. The small axial flow fan 51 is installed on the outer side wall of the positioning mounting plate 31. A cylindrical groove is opened through the outer side wall of the housing 1 at the installation position of the small axial flow fan 51. The small axial flow fan 51 passes through the cylindrical groove and is installed outside the housing 1. The air outlet of the small axial flow fan 51 faces the positioning mounting plate 31. A filter screen cover 52 is fitted to the outer side wall of the small axial flow fan 51 at the air inlet position. A threaded mounting ring 53 is provided on the outer side wall of the filter screen cover 52 near the position of the small axial flow fan 51. A corresponding annular threaded groove 54 is opened on the outer side wall of the small axial flow fan 51 at the housing position. The threaded mounting ring 53 and the annular threaded groove 54 are threaded together.
[0032] When the circuit board body 2 becomes hot during normal use and needs to be cooled down, simply turn on the small axial flow fan 51. Once turned on, the small axial flow fan 51 will cool the circuit board body 2 through air cooling. Note that the positioning mounting plate 31 and the liner 33 are both made of heat-conducting material, which allows the heat generated by the circuit board body 2 to be transferred to the side of the small axial flow fan 51 through heat conduction and then cooled by air cooling. The filter screen 52 is designed so that when the small axial flow fan 51 is in the air intake process, the filter screen 52 can isolate the dust particles carried in the airflow to the side of the filter screen 52, thereby achieving a safe protection effect for the small axial flow fan 51 while ensuring the cleanliness of the airflow. When the filter screen 52 becomes clogged due to long-term use, simply rotate the filter screen 52 until the threaded mounting ring 53 on its side is completely disengaged from the annular thread groove 54. Cleaning is completed and installation is done in the same way.
[0033] The filter screen cover 52 consists of a ring combined with a filter screen disc. The inner side wall of the filter screen cover 52 at the position of the ring has an annular mounting groove, and the filter screen disc is snapped into the annular mounting groove. This design can achieve a good dustproof effect while ensuring the stable installation of the filter screen cover 52.
[0034] The outer wall of the casing of the small axial flow fan 51 near the air outlet is provided with ventilation slots at equal intervals for exhaust; the ventilation slots facilitate the exhaust of the air blown out by the small axial flow fan 51, combined with the hot airflow, to the outside of the device.
[0035] When using this utility model, if it is necessary to install the circuit board body 2 into the housing 1, refer to the appendix of the instruction manual. Figure 3 As shown, at this time, the positioning mounting plate 31 needs to be installed on the inner wall of the enclosure 1 using the bolt mounting assembly according to the existing operating techniques. After the positioning mounting plate 31 is installed, the liner 33 only needs to be adjusted to a suitable position and the positioning T-shaped strip 34 on its side is pushed from top to bottom into the corresponding positioning T-shaped groove 35. When the positioning T-shaped strip 34 moves to the position where the second threaded groove 37 coincides with the first threaded groove 36, the fastening bolt 38 is used along the horizontal side to pass through the first threaded groove 36 and screwed to the bottom of the second threaded groove 37 to complete the positioning installation of the liner 33, and thus complete the installation of the circuit board body 2.
[0036] Here, due to the sliding friction between the positioning T-block 41 and the positioning T-groove 35, combined with the buffering effect of the support spring 42, a simple damping structure is formed. When the positioning T-strip 34 is pushed into the positioning T-groove 35 too fast, the positioning T-block 41 can be displaced downward to squeeze the support spring 42 to retract, thus achieving a buffering effect and preventing damage to the circuit board body 2 due to excessive insertion speed.
[0037] When the circuit board body 2 gets hot during normal use and needs to be cooled down, simply turn on the small axial flow fan 51. Once the small axial flow fan 51 is turned on, it will cool the circuit board body 2 through air cooling. It should be noted that the positioning mounting plate 31 and the liner 33 are both made of heat-conducting material, so that the heat generated by the circuit board body 2 can be transferred to the side of the small axial flow fan 51 through heat conduction and then cooled by air cooling. The filter screen 52 is set here so that the small axial flow fan 51 can isolate the dust particles carried in the airflow to the side of the filter screen 52 during the air intake process, thereby achieving the effect of safety protection for the small axial flow fan 51 while ensuring the cleanliness of the airflow.
[0038] It should also be noted that the outer side wall of the small axial flow fan 51 near the positioning mounting plate 31 is also provided with a threaded mounting ring 53, and the outer side wall of the positioning mounting plate 31 is correspondingly provided with an annular threaded groove 54. Therefore, when installing the two, the threaded mounting ring 53 on the side of the small axial flow fan 51 is simply passed through the cylindrical groove inside the housing 1 along the horizontal side and screwed to the bottom of the annular threaded groove 54 of the positioning mounting plate 31 to complete the installation.
[0039] It should be noted that the aforementioned small axial flow fan 51 can be powered by existing conventional operating techniques, whether by using a power supply unit or an external power cord. These are all existing operating techniques in Changchun and will not be described in detail here.
[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
