Description

Technical Field

[0001] This utility model relates to an intrinsically safe power supply module, belonging to the field of power supply equipment technology. Background Technology

[0002] Traditional intrinsically safe power modules often rely on bolt assemblies or hinge structures for mounting, which suffers from inherent drawbacks such as cumbersome installation procedures, low maintenance efficiency, and a lack of effective vibration damping design. Under high-frequency vibration or impact loads, the power supply body is prone to performance drift due to mechanical fatigue. Power supply clamping systems often use rigid pressure plates or wedge-shaped fixing structures, which not only have poor specification adaptability and are difficult to be compatible with modules of different sizes, but also severely hinder heat dissipation due to the sealed clamping method. The thermal stress concentration caused by local temperature rise significantly reduces the stability and lifespan of the equipment. Therefore, an intrinsically safe power module is proposed. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide an intrinsically safe power module that not only ensures efficient disassembly and maintenance but also effectively absorbs external impact and vibration energy through double-sided elastic support formed by buffer springs.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: This utility model provides an intrinsically safe power supply module, comprising:

[0005] The outer casing has an opening at its upper end;

[0006] The top plate is located above the outer shell, and side rods are provided on both sides of the top plate. The two side rods are snapped onto the side wall of the outer shell by a snap-fit ​​assembly.

[0012] A movable rod, which is mounted on a side rod and connected to the side rod at its middle section;

[0013] The first locking block is fixed to the lower end of the movable rod and is movably engaged in the first locking slot.

[0014] Preferably, the upper outer wall of the movable rod is provided with anti-slip texture.

[0015] Preferably, the inner housing has a placement slot for placing the power supply body, and the inside of the placement slot is slidably connected by bolts to a clamp for securing the power supply body.

[0016] Preferably, the bottom wall of the placement groove and the lower surface of the clamping plate are both connected with a plurality of spaced protruding ribs, which abut against the side wall of the power supply body.

[0017] Preferably, the power supply body is electrically connected to an electrical plug via a wire, and an annular groove is formed on the side wall of the electrical plug;

[0018] The lower end of the outer casing has an L-shaped opening, and a cover plate is provided on the opening. The cover plate presses the electrical plug into the opening through an annular groove.

[0019] Preferably, guide grooves are provided on both sides of the opening, and guide blocks are provided on both sides of the cover plate;

[0025] 1. This utility model uses a side rod snap-fit ​​fixing method between the top cover and the outer shell, and an inner shell structure with a guide rod sliding sleeve, which not only ensures quick disassembly and maintenance efficiency, but also forms double-sided elastic support through buffer springs, effectively absorbing external impact vibration energy and reducing the risk of performance degradation of the power supply body due to mechanical stress.

[0026] 2. This utility model achieves rapid clamping and release of the power supply body through a bolt-driven clamping plate structure.

[0046] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0047] Example 1

[0049] A buffer spring 7 is provided on the guide rod 6 and on both sides of the inner housing 4 to buffer the inner housing 4.

[0050] When the top plate 2 is fixed to the upper end of the outer shell 1 by the snap-fit ​​assembly 3 on the side rod 201, the inner shell 4 is installed inside the outer shell 1. At this time, the power supply body 5 is fixedly installed inside the outer shell 1, and the buffer spring 7 can buffer the inner shell 4, thus protecting the annular groove of the power supply body 5.

[0051] An electrical plug 501 is electrically connected to the power supply body 5 via a wire, and an annular groove 502 is provided on the side wall of the electrical plug 501.

[0052] The lower end of the outer casing 1 has an L-shaped opening 103. A cover plate 11 is provided on the opening 103. The cover plate 11 presses the electrical plug 501 into the opening 103 through the annular groove 502. When the cover plate 11 is installed inside the opening 103, a ring that matches the annular groove 502 is formed between the end of the cover plate 11 and the side wall of the opening 103. The electrical plug 501 is fixed inside the ring.

[0053] Guide grooves 104 are provided on both sides of the opening 103, and guide blocks 1101 are provided on both sides of the cover plate 11;

[0054] When the cover plate 11 is installed on the opening 103, the guide block 1101 is inserted into the guide groove 104.

[0055] A U-shaped spring piece 12 is fixed on the side wall of the outer shell 1, a second locking block 1201 is fixed on the outer wall of the spring piece 12, and a second locking groove 1102 is provided on the side wall of the cover plate 11.

[0056] When the cover plate 11 is installed on the opening 103, the second locking block 1201 is engaged in the second locking slot 1102.

[0057] The outer casing 1 has heat dissipation holes 105 on its side wall.

[0058] Example 2

[0059] like Figure 3 , Figure 7 and Figure 8 As shown, based on Embodiment 1, in this embodiment, side grooves 101 are provided on both sides of the outer shell 1, and a slot 102 is provided at the lower end of the side groove 101. Two side rods 201 are respectively inserted into the side grooves 101 on the same side.

[0060] The snap-fit ​​assembly 3 includes a movable rod 301, which is mounted on the side rod 201 and connected to the side rod 201 at its middle part. A snap-fit ​​block 302 is fixed to the lower end of the movable rod 301 and is movably snapped into the snap-fit ​​groove 102. Anti-slip texture is provided on the upper outer wall of the movable rod 301.

[0061] During installation, slide the side rod 201 on the top plate 2 into the side groove 101. When the top plate 2 abuts against the upper end of the outer shell 1, the locking block 302 engages inside the locking groove 102. In this way, the top plate 2 can be quickly installed inside the outer shell 1, thus realizing the quick installation of the power supply body 5.

[0062] When it is necessary to remove the power supply body 5 from the outer shell 1, press the upper end of the movable rod 301. At this time, the lower end of the movable rod 301 rotates outward, causing the locking block 302 to disengage from the locking slot 102. In this state, push the top plate 2 upward, and the top plate 2 slides upward. At this time, the power supply body 5 on the inner shell 4 can be removed from the outer shell 1, realizing the quick disassembly of the power supply body 5.

[0063] Example 3

[0064] like Figures 3-5 As shown, based on the above embodiment, in this embodiment, the inner shell 4 is provided with a placement groove 401 for placing the power supply body 5. The inside of the placement groove 401 is slidably connected to a clamping plate 9 for clamping the power supply body 5 by bolts 8. The bolts 8 are engaged with the top of the inner shell 4. The threaded end of the bolts 8 passes through the inner shell 4 and is rotatably connected to the clamping plate 9. When the bolts 8 are rotated, the bolts 8 can drive the clamping plate 9 to slide up or down on the inner shell 4, thereby achieving clamping or loosening of the power supply body 5.

[0065] The bottom wall of the placement slot 401 and the lower surface of the clamping plate 9 are both connected with a number of spaced-apart protrusions 10. The protrusions 10 abut against the side wall of the power supply body 5. The spaced distribution between adjacent protrusions 10 provides space for gas flow, thereby improving the heat dissipation efficiency of the power supply body 5.
