Description

Technical Field

[0001] The present invention relates to the technical field of plugging and unplugging devices, and in particular to a box-type power supply automatic plugging and unplugging device and method. Background Art

[0002] The box-type power automatic plug-in and pull-out device is an automated tool that integrates advanced technology and innovative design. With its excellent precision and high adaptability, it can seamlessly complete the quick and safe plug-in and pull-out actions between the power plug and the socket. The device ensures the accuracy of the plug-in and pull-out operations. At the same time, its durable structure and multiple safety protection mechanisms not only improve work efficiency, but also ensure the safety and reliability of the operation process.

[0003] In the prior art, box-type power supplies often need to be repaired when placed outdoors, which requires frequent plugging and unplugging operations. Long-term and frequent plugging and unplugging will wear the contact surface between the metal sheet and the elastic contact sheet, and will also reduce the elasticity of the elastic contact sheet, causing it to become loose and unable to tightly clamp the metal sheet, resulting in poor contact and affecting use.

[0004] In addition, when the plug and the socket are connected, a gap will appear between each other. Therefore, when the box-type power supply is placed outdoors and it suddenly rains heavily, rainwater will flow into the plug and the socket through the gap, causing a short circuit, which will damage the box-type power supply and cause a fire or electric shock hazard.

DETAILED DESCRIPTION

[0041] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0042] like Figures 1-15 1. A box-type automatic plug-in and pull-out device for a power supply shown in FIG. 1 includes a power supply body 1, a socket 2 being fixedly connected to the right end of the power supply body 1, a mounting groove 12 being provided in the middle of the end of the socket 2 away from the power supply body 1, a placement groove 13 being symmetrically provided at one end of the mounting groove 12, a plug 6 being provided on the inner wall of the mounting groove 12, a conductive plate 15 being symmetrically fixedly connected to the end of the plug 6 close to the power supply body 1, a circular hole 34 being pierced on both conductive plates 15, an elastic delay mechanism, a sealing mechanism, a limiting mechanism, a preliminary abutting mechanism and a secondary abutting mechanism being provided between the plug 6 and the socket 2, the elastic delay mechanism being provided allowing the plug 6 to move again when inserted into the socket 2, the sealing mechanism being provided allowing the gap between the plug 6 and the socket 2 to be sealed, the limiting mechanism being provided allowing the plug 6 to be limited and fixed to avoid being pulled out by external force and to prevent damage, the preliminary abutting mechanism being provided allowing a preliminary conductive connection operation to be performed, and the secondary abutting mechanism being provided allowing the stability of the connection to be enhanced;

[0043] like Figure 2 、 Figure 5 、 Figure 7 、 Figure 11 、 Figure 12As shown, the preliminary abutment mechanism includes first slots 8 opened on both sides of the mounting slot 12 corresponding to the end of the socket 2 away from the power supply body 1, and the two groups of first slots 8 and the placement slot 13 are connected through the second telescopic hole 27. The inner walls of the two second telescopic holes 27 are provided with conductive columns 16, and the two conductive columns 16 are fixedly connected to the first circular column 37 at one end close to each other, and also include first plug-in columns 14. The number of first plug-in columns 14 is the same as the number of first slots 8. The first plug-in columns 14 are inserted into the first slots 8 to squeeze the inclined surface on the conductive column 16 to make it move, and at the same time push the first circular column 37 to be inserted into the circular hole 34, so that the conductive column 16 and the conductive plate 15 are electrically connected.

[0044] like Figure 6 、 Figure 14 、 Figure 15 As shown, the re-abutment mechanism includes a square hole 25 connected to the placement slot 13, and push blocks 23 are provided on both sides of the inner wall of the square hole 25. A third sliding groove 41 is opened at the end away from each other of the two push blocks 23, and a second circular column 42 is provided on the inner wall of the two third sliding grooves 41. A third spring 40 is fixedly connected between the two groups of second circular columns 42 and the third sliding grooves 41. It also includes a circular groove 39 opened at one end close to each other of the first circular column 37, and a plurality of third telescopic holes 46 are pierced through the inner walls of the two circular grooves 39. An abutment column 38 is provided on the inner wall of each third telescopic hole 46. The second circular column 42 squeezes the inclined surface on the abutment column 38 to make it move and make the abutment column 38 fit tightly against the inner wall of the circular hole 34. When the push block 23 in the square hole 25 is pushed by an external force, it will move in the opposite direction along the inner wall of the square hole 25. The movement of the push block 23 drives the second circular column 42 in the third sliding groove 41 thereon to move together. Since the second circular column 42 is fixedly connected to the third sliding groove 41 by the third spring 40, the third spring 40 will play a role of buffering and resetting during the movement. When the second circular column 42 contacts the abutting column 38 in the circular groove 39 at one end of the first circular column 37, due to the design of its inclined surface, the abutting column 38 will be squeezed and move outward along the inner wall of the third telescopic hole 46. As the abutting column 38 moves The abutting post 38 is movable in the third telescopic hole 46, and they finally fit tightly against the inner wall of the circular hole 34, thereby achieving an abutting effect. The movement and final fit of the abutting post 38 in the third telescopic hole 46 ensures a tight connection between the abutting mechanism and the circular hole 34, preventing looseness or gaps. The presence of the third spring 40 not only provides a buffer for the movement of the push block 23 and the abutting post 38, but also ensures that when the external force disappears, they can automatically return to the initial position to prepare for the next abutting operation. Since the abutting post 38 can move in the third telescopic hole 46, the mechanism can adapt to circular holes 34 of different sizes or shapes, thereby improving its versatility and adaptability.

[0045] like Figure 3 、 Figure 4As shown, the preliminary contact mechanism also includes first slide grooves 19 defined at the upper and lower ends of the second telescopic hole 27. First sliders 18 are slidably connected to the inner walls of both sets of first slide grooves 19. A first spring 17 is fixedly connected between each set of first sliders 18 and the first slide grooves 19. The two sets of first sliders 18 are respectively fixedly connected to the two conductive posts 16. When the conductive posts 16 within the second telescopic hole 27 are subjected to force and move, the conductive posts 16 are fixedly connected to the first sliders 18 via the fixed connection. Therefore, their movement drives the first sliders 18 to slide within the first slide grooves 19. The first springs 17, acting as elastic elements connecting the first sliders 18 and the first slide grooves 19, not only provide an initial preload for the conductive posts 16 but also act as a buffer when the conductive posts 16 are subjected to external forces, preventing damage due to sudden impacts.

[0046] like Figure 2 、 Figure 5 、 Figure 8 As shown, the re-engagement mechanism also includes a second slot 10 provided at the bottom of the end of the socket 2 away from the power supply body 1. The second slot 10 and the square hole 25 are connected by a first telescopic hole 26. A lifting column 20 is provided on the inner wall of the first telescopic hole 26. Connecting rods 22 are rotatably connected to both sides of the top of the lifting column 20. The two connecting rods 22 are rotatably connected to two push blocks 23. An adjustment spring 24 is fixedly connected between the lifting column 20 and the square hole 25. The second plug 21 also includes a second plug 21. When inserted into the second slot 10, the second plug 21 presses against the inclined surface on the lifting column 20, pushing the lifting column 20 upward. The ingenious design of the second slot 10 and the square hole 25 through the first telescopic hole 26 not only achieves structural connectivity but also enhances overall stability during the insertion process. The design of the lifting column 20 incorporates a ramp mechanism, allowing the second plug 21 to automatically adapt to and push the lifting column 20 upward during insertion. As the lifting column 20 rises, the linkage between the connecting rod 22 and the push block 23 causes the push block 23 to move to the sides.

[0047] like Figure 15 As shown, the re-abutment mechanism also includes fourth slots 45 formed at both ends of the third telescopic hole 46. Each set of fourth slots 45 has a fourth slider 44 slidably connected to its inner wall. A fourth spring 43 is fixedly connected between each set of fourth sliders 44 and the fourth slots 45. Each set of fourth sliders 44 is fixedly connected to each abutment post 38. The combination of the fourth slots 45 and the fourth slider 44 provides a stable guide and support for the abutment post 38. This sliding connection not only ensures the linearity of the abutment post 38 during movement, but also maintains the overall stability of the structure through the preload force of the fourth spring 43.

[0048] like Figure 1 、 Figure 8 、 Figure 11As shown, the elastic delay mechanism includes a fixed frame 5 fixedly connected to the outer wall of the plug 6. A plurality of tension springs 4 are fixedly connected to one end of the fixed frame 5 near the socket 2. The other end of the plurality of tension springs 4 is fixedly connected to a movable frame 3. The movable frame 3 is arranged on the outer wall of the plug 6. The second plug 21 is fixedly connected to the movable frame 3. The two first plugs 14 are also fixedly connected to the movable frame 3. The two first plugs 14 are symmetrically distributed about the center line of the movable frame 3. The movable frame 3 is connected to the fixed frame 5 via the tension springs 4. This allows the movable frame 3 and the second plugs 21 and first plugs 14 thereon to maintain a certain degree of flexibility as the plug 6 approaches the socket 2. The stretching and recovery of the tension springs 4 adds a buffer period to the insertion process between the plug 6 and the socket 2, allowing the movable frame 3 to continue moving even after the plug 6 is fully in place.

[0049] like Figure 2 、 Figure 8 、 Figure 11 As shown, the elastic delay mechanism also includes a square slot 7 formed on the outer side of the first slot 8 at the end of the socket 2 away from the power supply body 1. Two electric push rods 28 are fixedly connected to one side of the inner wall of each square slot 7. The telescopic ends of the two electric push rods 28 are fixedly connected to the moving frame 3. The two electric push rods 28 are controlled by a synchronous controller to synchronize their telescopic movement.

[0050] like Figure 11 、 Figure 12 As shown, the sealing mechanism includes a sealing groove 9 defined between the square groove 7 and the first slot 8 at the end of the socket 2 away from the power supply body 1. An airbag 36 is provided on the inner wall of the sealing groove 9. The sealing mechanism also includes a sealing ring 29 fixedly connected between the first plug 14 and the electric push rod 28 at the end of the movable frame 3 close to the socket 2. The sealing ring 29 is inserted into the sealing groove 9 and squeezes the airbag 36, causing it to deform and tightly contact the inner wall of the sealing groove 9. The sealing groove 9 is cleverly designed to be located between the square groove 7 and the first slot 8. This positioning ensures that when the plug 6 is fully plugged into the socket 2, the sealing ring 29 can accurately enter the sealing groove 9. The provision of the airbag 36 further enhances the sealing effect. When the sealing ring 29 squeezes the airbag 36, the airbag 36 deforms and tightly fits the inner wall of the sealing groove 9, forming an effective sealing barrier that prevents external moisture, dust, or other contaminants from entering the interior of the socket 2, thereby protecting the safety and stability of the power connection.

[0051] like Figure 2 、 Figure 9 、 Figure 10 、 Figure 11As shown, the limiting mechanism includes a first through hole 11 passing through the mounting groove 12 and the sealing groove 9. There are two first through holes 11 and they are symmetrical about the center line of the mounting groove 12. Second slide grooves 31 are provided at the front and rear ends of the two first through holes 11. The inner walls of the two groups of second slide grooves 31 are slidably connected with second sliders 32. A second spring 33 is fixedly connected between each group of second sliders 32 and the second slide groove 31. A limiting column 30 is fixedly connected between the two groups of second sliders 32. It also includes limiting grooves 35 provided at the upper and lower ends of the plug 6. The two limiting grooves 35 and the two limiting columns 30 are respectively adapted in shape. The limiting mechanism achieves stable locking and limiting between the plug 6 and the socket 2 through an ingenious combination of the first through hole 11, the second slide groove 31, the second slider 32, the second spring 33 and the limiting column 30. When the plug 6 is fully inserted into the socket 2, the limiting column 30 can accurately slide into the limiting grooves 35 at the upper and lower ends of the plug 6. Since the limiting grooves 35 are adapted to the shape of the limiting columns 30, this design ensures a firm connection between the plug 6 and the socket 2 and effectively prevents the plug 6 from loosening during use.

[0052] A method for automatically plugging and unplugging a box-type power supply comprises the following steps:

[0053] Step 1: Insert the plug 6 into the installation slot 12 through the elastic delay mechanism, and insert the conductive plate 15 into the placement slot 13. Insert the first plug post 14 into the first slot 8 to press the inclined surface of the conductive post 16. The conductive post 16 pushes the first circular post 37 into the circular hole 34 to complete the initial contact operation.

[0054] Step 2: At the same time, the abutment mechanism is used to fix the position again, and the sealing mechanism is used to seal the gap between the plug 6 and the socket 2 to prevent moisture from penetrating;

[0055] Step 3: At the same time, the plug 6 is limited and fixed by the limiting mechanism to avoid shaking during use.

[0056] Working principle: When power connection is required, first start the electric push rod 28 to move the moving frame 3 toward the socket 2, so as to push the plug 6 smoothly into the installation slot 12 of the socket 2. At this time, the conductive plate 15 on the plug 6 also enters the placement slot 13. As the plug 6 goes deeper, the first plug post 14 fixedly connected to the moving frame 3 gradually enters the first slot 8 on the socket 2. At this time, the entry of the first plug post 14 will squeeze the inclined surface of the conductive post 16 set in the second telescopic hole 27. This squeezing causes the conductive post 16 to move toward the placement slot 13 and push the first circular post 37 into the circular hole 34 on the conductive plate 15. At this time, the contact between the conductive post 16 and the conductive plate 15 establishes a preliminary electrical connection. At the same time, due to the setting of the first slide groove 19, the first slider 18 and the first spring 17, the conductive post 16 can have a certain elastic restoring force after being squeezed, ensuring the stability and reliability of the connection.

[0057] When the lifting column 20 moves upward, the pushing block 23 in the square hole 25 is driven to move to both sides by the connecting rod 22. At this time, the second circular column 42 on the pushing block 23 moves and squeezes the inclined surface of the abutting column 38 set in the third telescopic hole 46, so that the abutting column 38 moves outward and fits tightly against the inner wall of the circular hole 34, thereby further enhancing the connection stability between the plug 6 and the socket 2 and avoiding wear between the elastic sheet in the plug 6 and the metal sheet on the socket 2, thereby extending the service life. At the same time, due to the arrangement of the fourth slide groove 45, the fourth slider 44 and the fourth spring 43, the abutting column 38 can have a certain elastic restoring force after being squeezed, ensuring its close contact with the inner wall of the circular hole 34;

[0058] At the same time, when the plug 6 is inserted into the socket 2, the sealing ring 29 fixedly connected to the movable frame 3 will gradually enter the sealing groove 9 on the socket 2. The entry of the sealing ring 29 will squeeze the airbag 36 set in the sealing groove 9, causing it to deform and come into close contact with the inner wall of the sealing groove 9, thereby forming an effective waterproof barrier to prevent moisture from penetrating through the gap and improving the sealing performance. Moreover, when the sealing ring 29 is inserted into the sealing groove 9, the sealing ring 29 will squeeze the inclined surface of the limiting column 30 set in the first through hole 11, causing the limiting column 30 to move in the direction close to the plug 6, thereby being inserted into the limiting groove 35. The cooperation between the limiting column 30 and the limiting groove 35 limits and fixes the plug 6, thereby preventing it from shaking or falling off during use.

[0059] When the plug 6 needs to be pulled out, the extension and retraction of the electric push rod 28 can drive the movable frame 3 and the plug 6 to move outward together, thereby realizing automatic plugging and unplugging.
