Abstract
Description
Technical Field
[0001] This invention relates to the technical field of power sockets, and more specifically to a waterproof protective door for a socket. Background Technology
[0002] Power sockets are among the most commonly used electrical accessories in daily life, including both fixed and portable sockets. Both types are found in many different living scenarios, such as kitchens, bathrooms, and outdoors. If accidentally submerged in water, splashed with water, or exposed to moisture, they can cause short circuits and electrical leaks. Protective shutters are an essential accessory for sockets, installed inside the socket corresponding to the socket hole to prevent foreign objects from being accidentally inserted and causing electric shock. In my invention patent No. 2026107105721 from the Chinese Patent Office, entitled "A Waterproof Socket," I proposed a socket structure consisting of a front shell, a partition plate, a bottom shell, and a sliding plate sealing mechanism to prevent safety risks when the socket encounters water or water enters its interior. However, this patent does not include a protective shutter structure to prevent foreign objects from being accidentally inserted into the socket. Adding an anti-misinsertion structure combined with the aforementioned sliding plate sealing mechanism to form a protective shutter would allow the socket to prevent both accidental insertion and electric shock, as well as leakage or short circuit risks when exposed to water. Summary of the Invention
[0003] The purpose of this invention is to address the issues of electric shock caused by accidental insertion into sockets and short circuits or leakage caused by water ingress in wet, submerged, or damp environments. This invention provides a simple and practical solution through a waterproof protective door structure for sockets, preventing risks caused by accidental insertion of foreign objects into the sockets during use, and protecting human and animal safety from water ingress that could lead to short circuits or leakage in wet, submerged, or damp environments.
[0004] To achieve the above objectives, the present invention adopts the following technical solution.
[0005] A waterproof protective door for a socket includes a faceplate, a partition, and a protective door closing mechanism.
[0006] The faceplate is installed on the front end of the socket and together with the bottom shell of the socket, it forms the socket outer shell. The faceplate has a socket hole for accommodating the plug prongs. The partition plate, with its front end corresponding to the faceplate and its bottom end corresponding to the bottom shell of the socket, is installed inside the socket. Each socket hole on the faceplate has a prong through hole for the plug prongs to pass through. The live wire and neutral wire sockets for connecting the power cord are located at the bottom end of the partition plate and correspond to the prong through holes on the partition plate. The live wire and neutral wire prongs of the plug must pass through the live wire and neutral wire sockets on the faceplate, and then through the prong through holes on the partition plate, to connect with the live wire and neutral wire sockets.
[0007] The protective door sealing mechanism consists of an upper sliding plate, a lower sliding plate, a sealing spring, and a return spring, installed in the interlayer between the front shell and the partition plate. The upper sliding plate's surface end is attached to the bottom end of the front shell, corresponding to and covering the live and neutral wire sockets of the front shell, preventing water from entering the socket through the sockets. The lower sliding plate's bottom end is attached to the surface end of the partition plate, covering the insertion through-holes of the partition plate corresponding to the live and neutral wire sockets of the front shell, preventing water from entering the bottom end of the partition plate through the insertion through-holes and contacting the live and neutral wire sleeves. The protective door sealing mechanism can activate the locking function when a foreign object is inserted into the live or neutral wire socket of the front shell, preventing the foreign object from accidentally entering the socket and contacting live parts. When the live and neutral wires of the plug are simultaneously inserted into the socket, the sliding insertion rod passes through and connects to the sleeve, separating the live and neutral wires passing through the protective door sealing mechanism, reducing the risk of water leakage or short circuit in the socket after the plug is inserted and connected to the power supply.
[0008] Preferably, the bottom end of the upper sliding plate has a closed boss surrounding the side, and the upper sliding plate surface end corresponds to the bottom end of the upper sliding plate, with its outer side corresponding to the inner side of the closed boss and fitting into the upper sliding plate. A gap is left between the surface end and the upper sliding plate to allow the two sliding plates to move towards each other. A spring post protruding to the side is provided on the side of the upper sliding plate perpendicular to the line connecting the center points of the live and neutral wire sockets on the front shell. A limiting boss surrounding the upper sliding plate and abutting against the bottom end of the front shell is provided on the side of the partition plate, with a return spring corresponding to the spring post. The two ends of the spring spring abut against the side of the upper sliding plate and the side of the limiting boss corresponding to the spring post, respectively. The upper sliding plate is positioned opposite the side with the spring post and the side with the spring post. One side of the spring post is perpendicular to both sides and corresponds to the inner side of the limiting boss, so that the upper slide plate is positioned and its lateral movement is limited to sliding back and forth to the side of the return spring; the closing spring is located in the middle of the two sockets for the live wire and neutral wire, and its two ends abut against the bottom end of the upper slide plate and the surface end of the lower slide plate respectively, pushing the upper slide plate to close the live wire and neutral wire sockets, and the lower slide plate to close the plug through hole with the partition plate; the upper slide plate has upper through holes on the same side as the live wire and neutral wire sockets. When the upper slide plate moves towards the side of the return spring, the two upper through holes respectively accommodate the live wire and neutral wire of the plug in the live wire and neutral wire sockets. The plug rod passes through the socket. The lower slide plate has two lower through holes corresponding to the upper through holes, also for accommodating the plug rod. At the bottom ends of the upper slide plate perpendicular to the side with the spring post, corresponding to the position of the closing spring, each has a sliding rounded corner. The partition plate has a raised guide slope corresponding to each sliding rounded corner, with the slope facing the direction of the return spring. The closing spring, sliding rounded corner, and guide slope are all located in the middle of the corresponding live and neutral wire sockets. When the plug rod is inserted into the socket from the live and neutral wire sockets, both rods simultaneously abut against and push the upper slide plate surface, causing the upper slide plate to move towards the bottom, deforming the closing spring, and sliding upwards... The sliding rounded corner at the bottom of the plate abuts against the guide slope of the partition plate, causing the upper slide plate to move towards the bottom and the side of the return spring. The closed boss side of the upper slide plate pushes the lower slide plate to slide in the same direction. The return spring is deformed by the thrust. The two slide plates move until the upper and lower through holes correspond to the faceplate insertion holes. The live wire and neutral wire plugs pass through the upper through hole of the upper slide plate, then through the lower through hole of the lower slide plate, and then through the plug through hole of the partition plate to connect to the plug sleeve. The closed spring pushes the upper slide plate against the faceplate again. The elastic force of the return spring pushes the upper slide plate against the plug and positions it. After the plug is pulled out, the return spring pushes the upper and lower slide plates to return to their original positions.
[0009] Preferably, the bottom end of the faceplate has a spring post on one side corresponding to the upper slide plate, and a locking groove is recessed into the bottom end. When an external object is inserted into a hole near the locking groove on the faceplate, the side of the upper slide plate with the spring post is pushed towards the bottom end by the pushing force. The sliding rounded corner of the bottom end abuts against the guide slope. Since the pushing force of the external object corresponds to the slope direction, the upper slide plate pushes the opposite side towards the face end with the guide slope as the fulcrum. Since the opposite side end itself abuts against the faceplate, the upper slide plate cannot move and is locked. When an external object is inserted into another hole on the faceplate, the upper slide plate moves towards the bottom end with the opposite side of the spring post, causing the closing spring to deform. The sliding rounded corner of the bottom end abuts against the guide slope of the partition plate, causing the side of the upper slide plate with the spring post to move towards the face end and the reset spring side. The face end slides into the locking groove, preventing the upper slide plate from moving further and locking it. After the external object is pulled out, the closing spring pushes the upper slide plate to reset.
[0010] Preferably, the bottom end of the upper slide plate is located between the two upper through holes and is provided with a dividing boss connecting the two opposing sides of the sealing boss, thus separating the two upper through holes. The lower slide plate is provided with a dividing groove corresponding to the dividing boss and fits into it. Furthermore, there is a gap between the bottom ends of the dividing boss and the dividing groove, allowing the upper and lower slide plates to move towards each other. The fitting of the inner side of the bottom boss of the upper slide plate with the outer side of the lower slide plate, along with the upper slide plate surface end fitting the bottom end of the shell and the lower slide plate bottom end fitting the dividing plate surface end, seals the live wire and neutral wire plugs passing through the through holes of the upper and lower slide plates, separating them from the outside of the protective door sealing mechanism. In addition, the fitting of the upper slide plate dividing boss and the lower slide plate dividing groove separates the live wire and neutral wire plugs inside the protective door sealing mechanism.
[0011] This invention utilizes a protective door sealing mechanism comprised of an upper sliding plate, a lower sliding plate, a sealing spring, and a return spring, installed in the space between the front panel and the partition plate. The upper sliding plate seals the live and neutral wire sockets on the front panel from inside the socket, preventing water from entering the socket through these sockets. The lower sliding plate seals the insertion holes on the partition plate corresponding to the live and neutral wire sockets, preventing water from entering the socket through the insertion holes on the partition plate and contacting the live and neutral wire sockets at the bottom. When no plug is inserted into the socket, the two layers of protection prevent water ingress and potential leakage or short circuits. The protective door sealing mechanism also... The device locks and prevents foreign objects from being accidentally inserted into the socket and coming into contact with live parts, thus preventing electric shock. When a plug is inserted into the socket, the inner side of the closed protrusion of the upper slide plate engages with the outer side of the lower slide plate, cutting off the connection between the live and neutral wires and the outside of the protective door sealing mechanism. In addition, the partition protrusion and partition groove between the upper and lower slide plates form an engaging structure that cuts off the connection between the live and neutral wires that pass through the protective door sealing mechanism, reducing the risk of leakage or short circuit of the live and neutral wires inside the socket when water enters the socket.

Detailed Implementation
[0028] The present invention will be further described below using a five-hole socket as an example, in conjunction with the accompanying drawings and specific embodiments. The present invention is also applicable to sockets with two-pole or three-pole sockets. It should be understood that the following description of the embodiments is merely illustrative and does not constitute a specific limitation of the present invention.
[0029] Reference Figures 1 to 11 This embodiment is a socket assembly with a five-hole socket, which is composed of a two-pole socket and a three-pole socket combined. The ground wire socket 103 of the three-pole socket is located in the middle of the two-pole socket. The five-hole socket can freely accept either a two-pole plug or a three-pole plug. It includes a front shell 1, a partition plate 5, and a protective door closing mechanism. The front end of the front shell 1 has a live wire socket 101, a neutral wire socket 102, and a ground wire socket 103 for inserting a plug. The partition plate 5 is located inside the socket corresponding to the bottom end of the front shell 1. Each socket on the front shell 1 has a corresponding... A plug-in through hole 501 is provided to accommodate the plug prongs. The bottom end of the partition plate 5 corresponds to the bottom shell of the socket, and the live wire and neutral wire socket sleeves of the socket are located at the bottom end of the partition plate. The protective door closing mechanism is installed in the interlayer between the partition plate 5 and the front shell 1, and consists of a two-pole closing mechanism corresponding to the two-pole socket and an oblique hole closing mechanism corresponding to the live wire and neutral wire sockets in the three-pole socket. The live wire and neutral wire prongs of the two-pole or three-pole plug need to pass through the socket holes of the front shell 1, then through the protective door closing mechanism, and then through the plug-in through hole 501 of the partition plate 5 before connecting to the socket sleeves.
[0030] Reference Figures 5 to 13The two-pole sealing mechanism includes an upper two-pole sliding plate 21, a lower two-pole sliding plate 41, a two-pole sealing spring 31, and a return spring 33. The lower two-pole sliding plate 41 corresponds to the two-pole socket position in the five-hole socket of the front shell 1, with its bottom end abutting the front end of the partition plate 5, covering and sealing the through holes 501 of the live and neutral wire sockets in the two-pole socket. Similarly, the upper two-pole sliding plate 21 corresponds to the two-pole socket position in the five-hole socket of the front shell 1, with its front end abutting the bottom end of the front shell 1, covering and sealing the live wire socket 101 and neutral wire socket 102 in the two-pole socket. Its bottom end corresponds to the front end of the lower two-pole sliding plate 41, leaving a gap between them to allow the two sliding plates to move towards each other. The bottom of the upper two-pole slide plate 21 is also provided with a two-pole closed protrusion 216 surrounding the side, and the inner side of the protrusion is fitted into the outer side of the lower two-pole slide plate 41. On the side of the upper two-pole slide plate 21 perpendicular to the line connecting the center points of the live wire socket 101 and the neutral wire socket 102 of the two-pole connector, there is a two-pole spring post 213 protruding to the side. The return spring 33 is installed corresponding to the two-pole spring post 213, and the two ends of the spring force abut against the side of the upper two-pole slide plate 21 and the side of the limiting protrusion 503 on the partition plate 5, respectively. The upper two-pole slide plate 21 has three parallel two-pole through holes 211. The middle two-pole through hole 211 corresponds to the ground wire socket 103 of the faceplate 1 and is used to accommodate the three-pole plug. The ground wire probe passes through, and the diode upper vias 211 on both sides are adjacent to the live wire socket 101 and the neutral wire socket 102 on the same side, respectively. When the diode upper slide plate 21 slides towards the return spring 33, the diode upper vias 211 on both sides move with it and correspond to the live wire socket 101 and the neutral wire socket 102, respectively, allowing the live and neutral wire probes of the plug to pass through. The diode lower slide plate 41 also has three diode lower vias 411, corresponding to the three diode upper vias 211 on the diode upper slide plate 21, also for accommodating the probes to pass through. The two ends of the diode closing spring 31 abut against the bottom end of the diode upper slide plate 21 and the top end of the diode lower slide plate 41, respectively, corresponding to the diode upper vias 211. The middle through hole position in hole 211 and diode lower through hole 411 pushes the diode upper slide plate 21 to fit against the shell 1 and close the live wire socket 101 and neutral wire socket 102, and pushes the diode lower slide plate 41 to fit against the partition plate 5 and close the corresponding live wire and neutral wire socket through hole 501. In addition, the middle of the diode sealing spring 31 can accommodate the ground wire plug through. The bottom ends of the diode upper slide plate 21 and the side with the diode spring post 213 are perpendicular to each other. Corresponding to the position of the diode sealing spring 31, each of them is provided with a diode sliding rounded corner 214. The side end of the partition plate 5 is provided with a raised guide slope 502 corresponding to the diode sliding rounded corner 214. The slope direction faces the reset spring 33.When the two-pole plug prongs are inserted into the socket through the live and neutral wire sockets, both prongs simultaneously abut against and push the upper plate 21 of the two-pole connector. The upper plate 21 moves towards the bottom, causing the two-pole sealing spring 31 to deform. The bottom sliding rounded corner 214 of the two-pole connector abuts against the guide slope 502 of the partition plate 5, causing the upper plate 21 to move towards the side of the return spring 33 and towards the bottom. The side of the two-pole sealing boss 216 pushes the lower plate 41 of the two-pole connector to slide in the same direction. The return spring 33 is deformed by the thrust, and the two-pole connectors on both sides... Hole 211 and diode lower via 411 move to correspond with the live and neutral wire sockets of the faceplate 1, respectively, allowing the insertion rod to pass through. Diode sealing spring 31 pushes diode upper slide plate 21 back to abut against faceplate 1. Diode upper via 211 and diode lower via 411 corresponding to ground wire socket 103 respectively abut against the bottom end of faceplate 1 and the front end of partition plate 5 and are closed. Return spring 33 pushes diode upper slide plate 21 to abut against the insertion rod and position it. After the plug is pulled out, return spring 33 pushes diode upper slide plate 21 to drive diode lower slide plate 41 to return to its original position.
[0031] Reference Figures 5 to 15 The bottom end of the faceplate 1 has a side edge of the two-pole spring post 213 corresponding to the two-pole upper slide plate 21, with a locking groove 104 recessed into the bottom end. When an external object is inserted into the insertion hole of the two-pole socket near the locking groove 104, the side of the two-pole upper slide plate 21 corresponding to the return spring 33 is pushed towards the bottom end by the pushing force. The bottom end of the two-pole sliding rounded corner 214 abuts against the guide slope 502. The pushing force of the external object corresponds to the slope direction, causing the two-pole upper slide plate 21 to push the opposite side towards the face end with the guide slope 502 as the fulcrum. Since the opposite side end itself abuts against the faceplate 1, the two-pole upper slide plate... 21 cannot move and is locked; when a foreign object is inserted into another hole in the two-pole socket, the upper plate of the two-pole plate 21 is pushed to move to the bottom end on the side opposite to the two-pole spring post 213, so that the two-pole closing spring 31 is deformed, and the bottom end two-pole sliding rounded corner 214 abuts against the guide slope 502 of the partition plate 5, so that the upper plate of the two-pole plate 21 moves to the face end and the side of the return spring 33 on the side corresponding to the return spring 33. The face end slides into the locking groove 104, preventing the upper plate of the two-pole plate 21 from continuing to move and locking it. After the foreign object is pulled out, the two-pole closing spring 31 pushes the upper plate of the two-pole plate 21 to reset.
[0032] Reference Figures 5 to 11At the bottom end of the upper plate 21, between the upper plate 31 and the upper plate through hole 211 on one side, there is a two-pole separating boss 215 connecting the two opposing sides of the two-pole sealing boss 216. The lower plate 41 has a two-pole separating groove 412 with a concave end that corresponds to the two-pole separating boss 215, dividing the overlapping surface of the two plates into two areas to separate the live wire and neutral wire plugs passing through the two-pole sealing mechanism. Furthermore, there is a gap between the bottom ends of the two-pole separating boss 215 and the two-pole separating groove 412, allowing the two plates to move towards each other. The outer side of the lower plate 41 is fitted with the inner side of the two-pole sealing boss 216 of the upper plate 21, cutting off the connection between the live wire and neutral wire plugs inserted into the socket and the outside of the two-pole sealing mechanism. The fitting of the two-pole separating boss 215 and the two-pole separating groove 412 cuts off the connection between the live wire and neutral wire plugs, reducing the possibility of leakage and short circuit when the live plugs inside the socket come into contact with water.
[0033] The lower two-pole slide plate 41 has a protruding two-pole buckle 413 on its end, and the upper two-pole slide plate 21 has a recessed two-pole groove 212 on its end, which corresponds to the two-pole buckle 413, so that the two slide plates and the two-pole closed spring 31 can be assembled into a component and then installed on the end of the partition plate 5 to improve the convenience of assembly.
[0034] Reference Figures 5 to 13The oblique hole sealing mechanism includes an upper oblique hole sliding plate 22, a lower oblique hole sliding plate 42, an oblique hole sealing spring 32, and a return spring 33. The bottom end of the lower oblique hole sliding plate 42 is attached to the front end of the partition plate 5, covering and sealing the through holes 501 of the live and neutral wire sockets in the three-pole socket. The front end of the upper oblique hole sliding plate 22 is attached to the bottom end of the shell 1, covering and sealing the live wire socket 101 and neutral wire socket 102 in the three-pole socket. Its bottom end corresponds to the front end of the lower oblique hole sliding plate 42, and a gap is left between them, allowing the two sliding plates to move towards each other. The bottom of the upper slide plate 22 is also provided with a slanted hole sealing boss 226 around the side, and the inner side of the slanted hole sealing boss 226 is correspondingly fitted with the outer side of the slanted hole lower slide plate 42; the slanted hole upper slide plate 22 and the two-pole upper slide plate 21 are provided with two-pole spring posts 213 on the same side, and are provided with slanted hole spring posts 223 protruding to the side, and the return spring 33 is installed corresponding to the slanted hole spring posts 223, with the two ends of the spring force abutting against the side of the slanted hole upper slide plate 22 and the side of the limiting boss 503 provided on the partition plate 5 respectively; the slanted hole upper slide plate 22 is adjacent to the live wire socket 101 and the neutral wire socket 102 on the same side. The upper slide plate 222 is provided with two oblique holes 221. When the upper slide plate 22 slides towards the return spring 33, the two oblique holes 221 move with it and correspond to the live wire socket 101 and the neutral wire socket 102 respectively, allowing the live wire and neutral wire plugs of the plug to pass through. The lower slide plate 42 is also provided with two oblique holes 421, corresponding to the upper slide plates 221 respectively, and is also used to accommodate the plugs to pass through. The two ends of the oblique hole closing spring 32 abut against the bottom end of the upper slide plate 22 and the top end of the lower slide plate 42 respectively, corresponding to the live wire and neutral wire on the surface. At the middle position of the socket, the upper sliding plate 22 of the inclined hole is pushed to fit against the shell 1 and close the live wire socket 101 and the neutral wire socket 102, and the lower sliding plate 42 of the inclined hole is pushed to fit against the partition plate 5 and close the corresponding live wire and neutral wire socket through hole 501; the two bottom ends of the upper sliding plate 22 of the inclined hole perpendicular to the side with the inclined hole spring post 223 are provided with inclined hole sliding round corners 224 corresponding to the position of the inclined hole closing spring 32, and the side end of the partition plate 5 is provided with protruding guide slopes 502 corresponding to the inclined hole sliding round corners 224, and the slope direction faces the reset spring 33;When the three-pole plug is inserted into the socket, the ground wire prong is inserted into the ground wire socket 103, and then passes through the upper two-pole through hole 211, the two-pole sealing spring 31, and the lower two-pole through hole 411 in the two-pole sealing mechanism. After the live wire and neutral wire prongs are inserted into the live wire and neutral wire sockets, they simultaneously abut against the end of the inclined hole upper sliding plate 22. The inclined hole upper sliding plate 22 moves towards the bottom, pushing the inclined hole sealing spring 32 to deform. The sliding rounded corner 224 at the bottom abuts against the guide slope 502 of the partition plate 5, causing the inclined hole upper sliding plate 22 to move towards the return spring 33 and... Moving towards the bottom, the oblique hole sealing boss 226 pushes the oblique hole lower slide plate 42 to slide in the same direction. The return spring 33 deforms under the thrust, and the oblique hole upper through hole 221 and oblique hole lower through hole 421 move to correspond with the live wire and neutral wire sockets of the faceplate 1, respectively, allowing the plug to pass through. The oblique hole sealing spring 32 pushes the oblique hole upper slide plate 22 to abut against the faceplate 1 again. The return spring 33 pushes the oblique hole upper slide plate 22 to abut against the plug and position it. After the plug is pulled out, the return spring 33 pushes the oblique hole upper slide plate 22 to drive the oblique hole lower slide plate 42 to return to its original position.
[0035] Reference Figures 5 to 15 The bottom end of the faceplate 1 has a side edge with a spring post 223 on one side corresponding to the inclined hole upper slide plate 22. A locking groove 104 is recessed into the bottom end. When an external object is inserted into the live and neutral wire sockets of the three-pole socket, near the locking groove 104, the side of the inclined hole upper slide plate 22 corresponding to the return spring 33 is pushed towards the bottom. The inclined hole sliding radius 224 at the bottom end abuts against the guide slope 502. The external object's pushing force corresponds to one side of the slope, causing the inclined hole upper slide plate 22 to move towards the face end with the guide slope 502 as a fulcrum. Since the opposite side end itself abuts against the faceplate 1, the inclined hole upper slide plate... 22 cannot move and is locked; when a foreign object is inserted into another socket of the live wire and neutral wire socket of the three-pole socket, the inclined hole upper slide plate 22 is pushed to move to the bottom end on the side opposite to the inclined hole spring post 223, so that the inclined hole closing spring 32 is deformed, and the bottom inclined hole sliding round corner 224 abuts against the guide slope 502 of the partition plate 5, so that the inclined hole upper slide plate 22 moves to the face end and the face end of the reset spring 33 on the side corresponding to the reset spring 33. The face end slides into the locking groove 104, preventing the inclined hole upper slide plate 22 from continuing to move and locking it. After the foreign object is pulled out, the inclined hole closing spring 32 pushes the inclined hole upper slide plate 22 to reset.
[0036] Reference Figures 5 to 11At the bottom end of the inclined hole upper slide plate 22, located between the inclined hole closing spring 32 and the inclined hole upper through hole 221 on one side, there is an inclined hole separating boss 225 connecting the two opposing sides of the inclined hole closing boss 226. The inclined hole lower slide plate 42 has an inclined hole separating groove 422 with a concave end that is fitted into the inclined hole separating boss 225, dividing the overlapping surface of the two slide plates into two areas to separate the live wire and neutral wire plugs passing through the inclined hole closing mechanism. Furthermore, there is a gap between the bottom ends of the inclined hole separating boss 225 and the inclined hole separating groove 422, allowing the two slide plates to move towards each other. The outer side of the inclined hole lower slide plate 42 is fitted into the inner side of the inclined hole closing boss 226 of the inclined hole upper slide plate 22, cutting off the connection between the live wire and neutral wire plugs inserted into the socket and the outside of the inclined hole closing mechanism. The fitting of the inclined hole separating boss 225 and the inclined hole separating groove 422 cuts off the connection between the live wire and neutral wire plugs, reducing the possibility of leakage and short circuit when the live plugs inside the socket come into contact with water.
[0037] The lower sliding plate 42 with the oblique hole has a protruding oblique hole buckle 423 on its end, and the upper sliding plate 22 with the oblique hole has a recessed oblique hole groove 222 that corresponds to the oblique hole buckle 423, so that the two sliding plates and the oblique hole closing spring 32 can be assembled into a component and then installed on the end of the partition plate 5 to improve the convenience of assembly.
[0038] Reference Figures 5 to 11 The return springs 33 of the two-pole sealing mechanism and the inclined hole sealing mechanism are mounted side by side in the same direction on the end of the partition plate 5. The bottom end of the two-pole sliding rounded corner 214 and the inclined hole sliding rounded corner 224 are aligned with the corresponding guide inclined surface 502 and are attached to each other on both sides. The end of the partition plate 5 is provided with a protrusion that abuts against the bottom end of the shell 1 and surrounds the limiting boss 503 of the two-pole sealing mechanism and the inclined hole sealing mechanism. One side of the limiting boss 503 abuts against the return springs 33 of the two-pole sealing mechanism and the inclined hole sealing mechanism respectively. The two-pole sealing mechanism and the inclined hole sealing mechanism abut against the inner side of the limiting boss 503 on the side opposite to the return spring 33 and the opposite sides of the two mechanisms respectively, so that the two-pole sealing mechanism and the inclined hole sealing mechanism can only slide back and forth in the direction of the return spring 33.

It should be understood that any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
