Technical Field
[0001] This utility model relates to the field of marine shore power plug technology, and more specifically, to a device for preventing marine shore power plugs from falling off. Background Technology
[0002] Marine shore power plugs are special interface devices used to connect ships to shore power systems when they are docked. They are used to replace the ship's own generator sets to provide power, thereby reducing pollution emissions and noise. However, when the ship is docked, the windows will sway with the waves, so the plugs are prone to falling off due to the swaying of the ship when they are plugged in. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a marine shore power plug anti-detachment device, which has the advantage of maintaining a stable connection and preventing detachment.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a marine shore power plug anti-detachment device, comprising a socket, an insulator fixedly installed inside the socket, a socket hole opened inside the insulator, a plug inserted inside the socket, a plug block fixedly installed inside the plug, the plug block being inserted into the socket hole, a connecting component fixedly installed on the outside of the plug block, and a locking block fixedly installed on the outside of the plug.
[0005] As a preferred technical solution of this utility model, the socket has a positioning groove inside, the locking block is slidably connected to the inside of the positioning groove, a fixing block is fixedly installed on the outside of the socket, a bracket is fixedly installed above the fixing block, a telescopic rod is fixedly installed at the bottom of the bracket, a spring is sleeved on the outside of the telescopic rod, a limit strip is fixedly installed at the bottom of the spring, and an inclined surface is opened at the bottom of the limit strip.
[0006] As a preferred embodiment of this utility model, a limiting block is fixedly installed on the outer side of the limiting strip, the limiting block is located above the first fixing block, and the limiting strip passes through the interior of the first fixing block.
[0007] As a preferred embodiment of this utility model, a fixing block two is fixedly installed on the outside of the socket, a connecting shaft is rotatably connected inside the fixing block two, a connecting block is fixedly installed above the connecting shaft, a flexible tube is fixedly installed on the outside of the connecting block, and a protective plug is fixedly installed on the outside of the flexible tube.
[0008] As a preferred embodiment of this utility model, there are two of each of the card blocks and positioning slots, and the two card blocks and the two positioning slots are slidably connected, with both positioning slots located on the outside of the plug.
[0009] As a preferred embodiment of this utility model, there are two hoses, both of which are fixedly connected to the protective plug, and there are two connecting blocks, with each hose being fixedly connected to one of the two connecting blocks.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This utility model features a bracket fixedly installed above a fixed block, a telescopic rod fixedly installed at the bottom of the bracket, a spring sleeved on the outside of the telescopic rod, and a limit strip fixedly installed at the bottom of the spring. The bottom of the limit strip has an inclined surface. When the locking block is installed along the sliding connection of the positioning groove, the locking block will first contact the limit strip, causing the locking block to press against the inclined surface. At the same time, because the inclined surface is inclined, it will drive the limit strip to move upward, causing the spring to contract, allowing the locking block to smoothly enter the side of the limit strip away from the inclined surface. When the locking block disengages from the bottom of the limit strip, the spring will provide elastic force to push the limit strip downward, thus limiting the position of the locking block and preventing it from resetting. When the hull sways with the waves, the socket and outlet will not fall off, achieving the effect of preventing detachment.

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 marine shore power plug anti-detachment device, including a socket 1, an insulator 2 fixedly installed inside the socket 1, a socket hole 3 opened inside the insulator 2, a plug 4 inserted into the socket 1, a plug block 5 fixedly installed inside the plug 4, the plug block 5 being inserted into the socket hole 3, a connecting component 6 fixedly installed on the outside of the plug block 5, and a locking block 7 fixedly installed on the outside of the plug 4.
[0021] When the boat is moored at the shore, the connecting component 6 is first pulled to the vicinity of the socket 1 by the power cord. Then, the connecting component 6 is aligned with the socket 1, and the plug 5 is inserted into the socket 3. Electricity is then transmitted through the plug 5 to the inside of the connecting component 6, and then through the power cord to the boat. This eliminates the need for the boat to generate its own electricity, thus saving the boat's overall resources.
[0022] The socket 1 has a positioning groove 8 inside, and the locking block 7 is slidably connected to the inside of the positioning groove 8. A fixing block 9 is fixedly installed on the outside of the socket 1. A bracket 10 is fixedly installed above the fixing block 9. A telescopic rod 11 is fixedly installed at the bottom of the bracket 10. A spring 12 is sleeved on the outside of the telescopic rod 11. A limit strip 13 is fixedly installed at the bottom of the spring 12. An inclined surface 14 is opened at the bottom of the limit strip 13.
[0023] After the locking block 7 is installed along the sliding connection of the positioning groove 8, the locking block 7 will first contact the limiting strip 13, causing the locking block 7 to press against the inclined surface 14. At the same time, since the inclined surface 14 is inclined, the inclined surface 14 will drive the limiting strip 13 to move upward, causing the spring 12 to contract, so that the locking block 7 will smoothly enter the side of the limiting strip 13 away from the inclined surface 14. When the locking block 7 is separated from the bottom of the limiting strip 13, the spring 12 will provide elastic force to push the limiting strip 13 further downward, so that the limiting strip 13 limits the position of the locking block 7, so that the locking block 7 will not reset. When the hull sways with the waves, the socket 1 and the plug 3 will not fall off, achieving the effect of preventing falling off.
[0024] Among them, a limiting block 15 is fixedly installed on the outer side of the limiting strip 13, the limiting block 15 is located above the fixing block 9, and the limiting strip 13 passes through the inside of the fixing block 9.
[0025] The main function of the limiting block 15 is to limit the limiting strip 13, so that after the limiting strip 13 passes through the inside of the fixed block 9, its position is fixed under the elastic force of the spring 12, thereby improving the overall stability.
[0026] Among them, a fixing block 16 is fixedly installed on the outside of the socket 1, a connecting shaft 17 is rotatably connected inside the fixing block 16, a connecting block 18 is fixedly installed above the connecting shaft 17, a flexible hose 19 is fixedly installed on the outside of the connecting block 18, and a protective plug 20 is fixedly installed on the outside of the flexible hose 19.
[0027] When the hull does not need to be charged, the protective plug 20, through the connection of the hose 19, causes the connecting block 18 to move through the rotational connection between the connecting shaft 17 and the fixed block 16, so that the protective plug 20 will be inserted into the inside of the socket 1, thereby keeping the inside of the socket 1 sealed and preventing water vapor corrosion caused by the high humidity at the seaside, thus providing effective protection for the socket 1.
[0028] There are two of each of the two locking blocks 7 and two positioning slots 8. The two locking blocks 7 and the two positioning slots 8 are slidably connected, and the two positioning slots 8 are located on the outside of the plug 4.
[0029] The two locking blocks 7 facilitate alignment when the socket 1 and plug 4 are inserted and mated, thereby improving the efficiency of the insertion.
[0030] There are two hoses 19, both of which are fixedly connected to the protective plug 20. There are also two connecting blocks 18, with the two hoses 19 being fixedly connected to the two connecting blocks 18 respectively.
[0031] The two hoses 19 are fixedly connected to the protective plug 20, so that when the protective plug 20 is not in use, it can be hung on the outside of the socket 1 by the fixing effect of the two hoses 19 and the connecting block 18, so as to prevent it from being lost.
[0032] Working principle and usage process of this utility model:
[0033] First, a plug block 5 is fixedly installed inside the plug 4 and plugs into the socket 3. At the same time, a connecting component 6 is fixedly installed on the outside of the plug block 5 and a locking block 7 is fixedly installed on the outside of the plug 4. When the ship is moored on the shore, the connecting component 6 is first pulled to the vicinity of the socket 1 by the power cord. Then, the connecting component 6 is aligned with the socket 1, so that the plug block 5 is plugged into the socket 3. Thus, electricity is transmitted through the plug block 5 to the inside of the connecting component 6, and then transmitted to the ship through the power cord. This way, the ship does not need to generate its own electricity, thus saving the overall resources of the ship.
[0034] Secondly, a bracket 10 is fixedly installed above the fixed block 9, and a telescopic rod 11 is fixedly installed at the bottom of the bracket 10. A spring 12 is sleeved on the outside of the telescopic rod 11, and a limit strip 13 is fixedly installed at the bottom of the spring 12. The bottom of the limit strip 13 has an inclined surface 14. When the locking block 7 is installed along the sliding connection of the positioning groove 8, the locking block 7 will first contact the limit strip 13, causing the locking block 7 to press against the inclined surface 14. At the same time, because the inclined surface 14 is inclined... When tilted, the tilted surface 14 will move the limiting bar 13 upward, causing the spring 12 to contract, allowing the locking block 7 to smoothly enter the side of the limiting bar 13 away from the tilted surface 14. When the locking block 7 disengages from the bottom of the limiting bar 13, the spring 12 will provide elastic force to push the limiting bar 13 downward, so that the limiting bar 13 limits the position of the locking block 7, thus preventing the locking block 7 from resetting. When the hull sways with the waves, the socket 1 and the plug 3 will not fall off.
[0035] Finally, a connecting shaft 17 is rotatably connected inside the fixed block 16, a connecting block 18 is fixedly installed above the connecting shaft 17, a flexible hose 19 is fixedly installed on the outside of the connecting block 18, and a protective plug 20 is fixedly installed on the outside of the flexible hose 19. When the hull does not need to be charged, the protective plug 20, through the connection of the flexible hose 19, causes the connecting block 18 to move through the rotatable connection between the connecting shaft 17 and the fixed block 16, so that the protective plug 20 will be inserted into the inside of the socket 1, thereby keeping the inside of the socket 1 sealed and preventing water vapor corrosion caused by the high humidity at the seaside, thus providing effective protection for the socket 1.
