Description

Technical Field

[0001] This utility model relates to the field of charger technology, specifically a mining charger with a protective structure. Background Technology

[0002] Mining chargers are commonly used devices for supplying power and charging electrical equipment underground in mines. According to patent authorization announcement number CN219554619U, a mining charger is disclosed, comprising: a body, a handle, a display screen, indicator lights, and a switch. The handle is connected to the top of the body, the display screen is connected to the front of the body, indicator lights are connected to the front of the body near the display screen, and a switch is connected to the front of the body near the indicator lights. When dust protection is required, the dustproof net is moved to the side of the heat dissipation hole and inserted. The dustproof net slides through the heat dissipation hole during insertion, and the sliding motion of the dustproof net moves the locking block. When the locking block moves to the bottom of the locking groove, it pulls the squeezing rod.

[0003] However, existing chargers connect via plugs, but the limited space underground in mines makes the plug interface susceptible to impact damage. Furthermore, the chargers are heavy and difficult to transport underground, resulting in poor portability. Therefore, improvements to the existing technology are needed. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A mining charger with a protective structure includes a body 1. A plug-in interface 3 is fixedly connected to the center of the front of the body 1. A bracket 4 is fixedly connected to the rear of the lower end of the body 1. Two symmetrically distributed casters 5 are mounted on the front of the lower end of the body 1 via bearings. A portable mechanism 6 is provided on the bracket 4. A protective cover 8 is hinged to the center of the front of the body 1. A connecting frame 9 is fixedly connected to the outside of the protective cover 8. A connecting plate 10 is fixedly connected to the front of the body 1. A pull ring rod 11 is slidably connected inside the connecting plate 10. A limit post 12 is fixedly connected to the lower end of the pull ring rod 11. A spring 13 is provided on the outside of the pull ring rod 11.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5A vent grille 7 is fixedly connected to the lower front of the body 1. A display screen 2 is installed on the inclined surface of the upper end of the body 1. The display screen 2 can display the working status of the charger. A protective cover 8 covers the outside of the plug interface 3. The limiting post 12 is slidably connected to the connecting frame 9. The protective cover 8 can protect the plug interface 3. One end of the spring 13 is fixedly connected to the limiting post 12, and the other end of the spring 13 is fixedly connected to the connecting plate 10. The spring 13 can automatically reset the limiting post 12 through its elastic force.

[0025] Please see Figure 2 , Figure 6 , Figure 7 The portable mechanism 6 includes a connecting shaft 61. The connecting shaft 61 is mounted on the back of the bracket 4 via a bearing. A pull frame 62 is fixedly connected to the outer side of the connecting shaft 61. A gear 63 is fixedly connected to the middle of the outer side of the connecting shaft 61. A flip frame 64 is hinged to the lower end of the bracket 4. A slanted snap-fit ​​frame 65 is fixedly connected to the upper end of the flip frame 64. A second spring 66 is provided at the upper end of the flip frame 64. The slanted snap-fit ​​frame 65 can limit the use angle of the pull frame 62 through the gear 63 and the connecting shaft 61. One end of the second spring 66 is fixedly connected to the body 1. The other end of the second spring 66 is fixedly connected to the flip frame 64. The slanted snap-fit ​​frame 65 is snapped with the gear 63. The second spring 66 can support the flip frame 64 through its elasticity.

[0026] The specific implementation process of this utility model is as follows: In use, the deflecting pull frame 62 drives the connecting shaft 61 to rotate. During the rotation of the connecting shaft 61, the gear 63 can rotate. During the rotation of the gear 63, the inclined plate locking frame 65 can move and drive the tilting frame 64 to deflect, and compress the second spring 66. When the pull frame 62 is parallel to the bottom surface of the body 1, the second spring 66 returns to its original position. The second spring 66 can use its elasticity to drive the inclined plate locking frame 65 above the tilting frame 64 to engage with the tooth groove of the gear 63 after adjustment. Then, the body 1 can be moved by the universal wheel 5, which makes the body 1 easier to carry.

[0027] When in use, after flipping open the protective cover 8, insert the plug into the inside of the connector 3, and pull the pull ring rod 11 upward. The pull ring rod 11 moves the limiting post 12 and compresses the spring 13. After the protective cover 8 covers the plug inside, release the pull ring rod 11, and the spring 13 returns to its original position. The spring 13 can use its elasticity to drive the limiting post 12 to slide into the inside of the connecting frame 9, which makes the protective cover 8 more stable and can effectively protect the outside of the connector 3.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
