However, most existing locking mechanisms, while ensuring a secure lock, suffer from complex structures and cumbersome operation, resulting in inconvenience and low efficiency when plugged in. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a low-voltage shore power plug locking mechanism, which has the advantages of convenient and quick locking.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a low-voltage shore power plug locking mechanism, comprising a distribution box, a connecting seat fixedly installed on the right side of the distribution box, a socket fixedly installed on the right side of the connecting seat, a socket having an internal insertion hole, a connecting plate fixedly installed on the outer side of the connecting seat, a plug on the right side of the connecting seat, a plug having an internal insertion block fixedly installed inside the plug, the insertion block being inserted into the insertion hole, a connecting rod fixedly installed on the outer side of the plug, a bolt engaging on the outer side of the connecting rod, a pressing block sleeved on the outer side of the bolt, and a pressing handle rotatably connected to the top of the bolt.

[0005] As a preferred embodiment of this utility model, a second connecting plate is fixedly installed on the right side of the connecting seat. A sliding groove is provided inside the second connecting plate, and a slider is slidably connected inside the sliding groove. A connecting block is fixedly installed in front of the slider, and a pressing rod is fixedly installed in front of the connecting block. A fixing rod is fixedly installed in front of the second connecting plate, and a connecting wire is fixedly installed on the right side of the plug.

[0006] As a preferred embodiment of this utility model, a fixing block is fixedly installed above the second connecting plate, and a telescopic rod is fixedly installed at the bottom of the fixing block. A spring is sleeved on the outside of the telescopic rod, and both the telescopic rod and the spring are located above the connecting block and are fixedly connected to the connecting block.

[0007] As a preferred embodiment of this utility model, there are two connecting plates located on the front and rear sides of the socket, and there are two connecting rods, both of which are L-shaped.

[0008] As a preferred embodiment of this utility model, there are two fixing rods, both of which are cylindrical and are located above the extrusion rod.

[0009] As a preferred embodiment of this utility model, there are two bolts, two extrusion blocks, and two extrusion handles, with the two extrusion blocks and the two sliders located above the two connecting plates.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model features a plug on the right side of the connector, with a plug block fixedly installed inside the plug and inserted into the socket. A connecting rod is fixedly installed on the outside of the plug, with a bolt engaged on the outside of the connecting rod. A pressing block is sleeved on the outside of the bolt, and a pressing handle is rotatably connected to the top of the bolt. When power is needed, the plug block is first inserted into the socket to establish the circuit connection. At this time, the plug will be located on the right side of the socket, and the connecting rod will be inserted into the first connecting plate during installation. The bolt is then engaged with both the first connecting plate and the connecting rod, causing the first connecting plate to press the connecting rod, thus fixing the connecting rod. Simultaneously, the pressing handle is rotated to press the pressing block, locking the connecting rod. Since the connecting rod and the plug are fixedly connected, the socket and plug are effectively locked, and the operation is simple, improving installation efficiency.

A connecting wire is fixedly installed on the right side of the plug, positioned above the fixing rod. The pressing rod, through the sliding connection between the slider and the chute, compresses the connecting wire downwards, making it form a horizontal S-shape. When the waves cause the ship to sway, the connecting wire is pulled. The pressing rod then slightly pushes the connecting wire upwards, reducing the pulling force and providing some clearance to prevent excessive tension and breakage due to straight-line pulling. Furthermore, the connecting wire, positioned above the fixing rod, avoids friction with the ground, thus protecting its outer sheath. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] like Figures 1 to 5 As shown, this utility model provides a low-voltage shore power plug locking mechanism, including a distribution box 1. A connecting seat 2 is fixedly installed on the right side of the distribution box 1. A socket 3 is fixedly installed on the right side of the connecting seat 2. A socket 4 is opened inside the socket 3. A connecting plate 5 is fixedly installed on the outside of the connecting seat 2. A plug 6 is provided on the right side of the connecting seat 2. A plug block 7 is fixedly installed inside the plug 6. The plug block 7 is plugged into the socket 4. A connecting rod 8 is fixedly installed on the outside of the plug 6. A bolt 9 is engaged on the outside of the connecting rod 8. A pressing block 10 is sleeved on the outside of the bolt 9. A pressing handle 11 is rotatably connected to the top of the bolt 9.

[0021] When power is needed, first insert the plug 7 into the socket 4 to connect the circuit. At this time, the plug 6 will be located on the right side of the socket 3, and the connecting rod 8 will be inserted into the connecting plate 5 during installation. Then, the bolt 9 will engage with the connecting plate 5 and the connecting rod 8 respectively, so that the connecting plate 5 will press the connecting rod 8, thereby fixing the connecting rod 8. At the same time, rotate the pressing handle 11 to press the pressing block 10, so that the connecting plate 5 will lock the connecting rod 8. Since the connecting rod 8 and the plug 6 are fixedly connected, the socket 3 and the plug 6 are locked, which is simple to operate and improves the installation efficiency.

[0022] Among them, a connecting plate 12 is fixedly installed on the right side of the connecting seat 2. A sliding groove 13 is opened inside the connecting plate 12. A slider 14 is slidably connected inside the sliding groove 13. A connecting block 15 is fixedly installed in front of the slider 14. A pressing rod 16 is fixedly installed in front of the connecting block 15. A fixing rod 17 is fixedly installed in front of the connecting plate 12. A connecting wire 21 is fixedly installed on the right side of the plug 6.

[0023] The connecting line 21 is located above the fixed rod 17. At the same time, the squeezing rod 16, through the sliding connection between the slider 14 and the groove 13, squeezes the connecting line 21 downward, making the connecting line 21 into a horizontal S-shape. When the waves cause the hull to sway, the connecting line 21 will be pulled. At this time, the connecting line 21 will move slightly upward through the squeezing action of the squeezing rod 16, reducing the pulling force of the connecting line 21 and giving the connecting line 21 a certain amount of slack space to prevent the connecting line 21 from being pulled too much and breaking due to straight pulling. At the same time, the connecting line 21 is placed above the fixed rod 17 and will not rub against the ground, thus protecting the outer skin of the connecting line 21.

[0024] Among them, a fixing block 18 is fixedly installed on the top of the connecting plate 12, and a telescopic rod 19 is fixedly installed on the bottom of the fixing block 18. A spring 20 is sleeved on the outside of the telescopic rod 19. The telescopic rod 19 and the spring 20 are both located above the connecting block 15 and are fixedly connected to the connecting block 15.

[0025] The connecting block 15 is always provided with elastic force by the spring 20 and moves downward through the sliding connection between the slider 14 and the groove 13, so that the extrusion rod 16 always extrudes the connecting line 21, keeping the connecting line 21 in a state of excess space.

[0026] Among them, there are two connecting plates 5, which are located on the front and rear sides of the socket 3 respectively, and there are two connecting rods 8, both of which are L-shaped.

[0027] The two connecting rods 8 are inserted into the two bolts 9 respectively, so that the insertion hole 4 and the insertion block 7 are aligned when they are inserted.

[0028] There are two fixing rods 17, both of which are cylindrical and are located above the extrusion rod 16.

[0029] The main function of the two fixing rods 17 is to support the connecting line 21 and prevent the connecting line 21 from touching the ground.

[0030] There are two bolts 9, two extrusion blocks 10 and two extrusion handles 11. The two extrusion blocks 10 and the two sliders 14 are located above the two connecting plates 5 respectively.

[0031] The two compression handles 11 are rotatably connected by two bolts 9, so that the bottom of the two compression handles 11 presses the two compression blocks 10 respectively, thereby fixing the two connecting plates 5 to the two connecting rods 8 respectively, achieving a quick locking effect.

[0032] Working principle and usage process of this utility model:

[0033] Firstly, because a plug 6 is provided on the right side of the connector 2, a plug block 7 is fixedly installed inside the plug 6 and plug block 7 is inserted into the socket 4. At the same time, a connecting rod 8 is fixedly installed on the outside of the plug 6, a bolt 9 is engaged on the outside of the connecting rod 8, a pressing block 10 is sleeved on the outside of the bolt 9, and a pressing handle 11 is rotatably connected to the top of the bolt 9. When it is necessary to plug in the power, the plug block 7 is first inserted into the socket 4 to realize the circuit connection. At this time, the plug 6 will be located on the right side of the socket 3, and the connecting rod 8 will be inserted into the inside of the connecting plate 5 during the installation process. Then, the bolt 9 is engaged with the connecting plate 5 and the connecting rod 8 respectively, so that the connecting plate 5 presses the connecting rod 8, thereby fixing the connecting rod 8.

[0034] At the same time, the squeezing handle 11 is rotated to squeeze the squeezing block 10, so that the connecting plate 15 drives the connecting rod 8 to be locked. Since the connecting rod 8 and the plug 6 are fixedly connected, the socket 3 and the plug 6 are locked, and the operation is simple, which improves the installation efficiency.

[0035] Secondly, a slider 14 is slidably connected inside the slide groove 13. A connecting block 15 is fixedly installed in front of the slider 14, and a pressing rod 16 is fixedly installed in front of the connecting block 15. A fixing rod 17 is fixedly installed in front of the connecting plate 12. A connecting line 21 is fixedly installed on the right side of the plug 6, and the connecting line 21 is located above the fixing rod 17. Simultaneously, the pressing rod 16, through the sliding connection between the slider 14 and the slide groove 13, causes the connecting line 21 to be pressed downwards, making the connecting line 21 form a horizontal S-shape. When the waves cause the hull to sway, the connecting line 21 will be pulled. At this time, the connecting line 21 will move slightly upwards due to the pressing action of the pressing rod 16, reducing the pulling force of the connecting line 21 and providing a certain amount of clearance to prevent the connecting line 21 from breaking due to excessive pulling force caused by straight-line pulling.

[0036] Finally, since the connecting wire 21 is placed above the fixing rod 17, it will not rub against the ground, thus protecting the outer sheath of the connecting wire 21.
