Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment connection, and in particular to a multifunctional waterproof and anti-detachment connector for a generator. Background Art

[0002] The generator connector is a device used to connect the generator to the wires. It is mainly plugged into the generator and then connected to other devices through the USB port, type-c port and other interfaces on its surface to achieve power supply to other devices in a manner similar to a socket.

[0003] The waterproof and anti-drop sockets currently on the market mainly achieve the purpose of waterproofing by closing the waterproof box that can be flipped on the outside of the socket after the wire plug is plugged into the socket; and in terms of anti-dropping, an anti-slip pad is usually added to the surface of the socket to improve the stability of the connection between the plug and the socket, or the plug is elastically compressed when the plug is inserted through a fastening structure, which can prevent it from loosening while facilitating plugging and unplugging; however, the waterproof box structure can only protect against small water droplets falling vertically, and has poor protection against splashing and splashing water. When water penetrates into the waterproof box, it will cause the socket to leak electricity; for USB interfaces and type-c interfaces, it is impossible to open holes on their surfaces like plugs, so they are more likely to loosen; the prior art has proposed solutions, such as a waterproof socket with patent publication number CN105896162B; by A water guide groove is provided on the side to guide out water that has seeped into the gap between the cover plate and the enclosure plate to prevent water from entering the functional groove. A threading hole is provided at the bottom of the socket body to communicate with the wire lead-out groove. When the cover plate covers the socket body, the two semicircular holes form a complete circular hole to buckle the wire passing through the threading hole to prevent water from touching the plug board and the wire. Patent publication number CN109687228B is a method for preventing a USB terminal from falling off. A pressing piece connected to a spring through a rotating shaft is provided on the side wall of the overall shell of the USB terminal. When the USB connector is inserted, the connector contacts the pressing piece and the entire pressing piece is lifted up by the bent portion at one end of the pressing piece. After the connector is connected to the outer wall of the terminal, the pressing piece is pressed back due to the elasticity of the spring to realize the function of clamping the connector. In addition, the design of the mounting frame and the rubber frame reduces the impact of the vibration and deformation of the connecting side wall on the USB terminal.

[0004] Although the prior art solves the problem that the waterproof box cannot effectively protect against splashing and water splashing, and the problem that the connector and the socket are prone to loosening, the following problems still exist: when used on a generator, it is necessary to ensure that it has stronger waterproof performance to face the outdoor construction environment, and the generator will vibrate at high frequency when generating electricity. Under the condition of high-frequency vibration, the use of an elastic anti-loosening structure cannot effectively prevent the plug from loosening under high-frequency vibration, so the connector also needs to ensure that it will not loosen under high-frequency vibration conditions. In order to be suitable for common data cables on the market and conditions that require frequent plugging and unplugging, the method of directly locking or modifying the plug is not applicable; under the high-frequency vibration of the generator, the fluidity of water falling on the waterproof cover will increase, and at the same time, under vibration conditions, the static waterproof structure of the waterproof cover will produce a gap, thereby causing water to penetrate into the connection position between the plug and the socket, and once too much water accumulates in the waterproof box and splashes, it will be easier for water to reach the connection position of the plug and socket, thereby causing a safety accident.

[0005] In view of the above situation, in order to overcome the above technical problems, the present invention designs a multifunctional waterproof and anti-detachment connector for a generator. Summary of the invention

[0006] The present invention provides a multifunctional waterproof and anti-detachment connector for a generator, which solves the problem that a plug is loosened and water flows in because of the high-frequency vibration working condition of the generator when the connector is used on the generator. By arranging a driving mechanism, a locking mechanism and a drainage mechanism, when the generator vibrates, the driving mechanism absorbs the vibration and rotates unidirectionally, the rotation of the driving mechanism drives the locking cam to rotate, and the rotation of the locking cam drives the locking arm to push the plug obliquely, thereby completing a dynamic locking process, and the locking cam is an Archimedean cam structure and a lever principle to enable the drainage mechanism to slowly inhale and reset in the lifting section of the locking cam, and quickly apply swirling wind pressure to a position prone to water seepage when the lifting section is switched to the return section, so as to prevent water from infiltrating into the inner cover layer, thereby improving the waterproof performance and anti-loosening performance of the connector.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A multifunctional waterproof and anti-detachment connector for a generator, which is used on the generator and includes a connector body and a waterproof cover; it also includes a driving mechanism, a locking mechanism and a drainage mechanism; the waterproof cover includes an inner cover layer and an outer cover layer; the inner cover layer is connected to the front of the connector body; the outer cover layer is rotatably mounted on the connector body; the driving mechanism is connected to the connector body, and when the generator vibrates, the driving mechanism absorbs the vibration and performs unidirectional rotational movement; the locking mechanism includes a main body locking assembly and a plug locking assembly; the main body locking assembly is connected to the back of the connector body; the plug locking assembly is connected to the front of the connector body, and the driving mechanism rotates to drive the plug locking assembly to perform oblique telescopic movement; the drainage mechanism is connected to the plug locking assembly, and when the plug locking assembly performs oblique telescopic movement, it drives the drainage mechanism to move in the opposite horizontal direction.

[0009] Preferably, a mounting groove is provided in the connector body; the driving mechanism includes a vibrating swing arm, a driving ratchet and a pull-back spring; the vibrating swing arm is rotatably mounted in the mounting groove; the driving ratchet is mounted in the mounting groove and cooperates with the vibrating swing arm; one end of the pull-back spring is connected to the vibrating swing arm, and the other end is connected to the mounting groove.

[0010] In the above scheme, since the vibration generated when the generator is working can be absorbed by the vibrating swing arm, the vibration swing arm can be used to drive the driving ratchet to rotate, and when the driving ratchet rotates, it will drive the plug locking assembly and the drainage mechanism to work, and the reset force of the pull-back spring can help the vibrating swing arm to reset, so as to swing again, and the driving ratchet can achieve unidirectional rotation, thereby achieving unidirectional driving of the plug locking assembly and the drainage mechanism, avoiding the drainage mechanism from causing water flow disorder, and achieving the purpose of rapid drainage by utilizing the high-frequency vibration of the generator itself, so that the water entering the outer cover layer can be discharged and avoid entering the inner cover layer.

[0011] Preferably, a counterweight is provided at the unhinged end of the vibrating swing arm.

[0012] In the above scheme, the counterweight block can make the vibration amplitude of the vibrating swing arm larger when the generator vibrates, and can increase the driving force generated by the vibrating swing arm when it vibrates, thereby enhancing the driving effect.

[0013] Preferably, the main body locking assembly includes a snap ring, a snap groove, a snap block and a snap spring; the snap ring is arranged on the back side of the connector body; the snap groove is provided in the snap ring; the snap block is slidably installed in the snap groove, and a connecting groove is provided on the snap block; the snap spring is connected between the snap block and the snap groove, and the connecting groove extends half way out of the snap groove when the snap spring is not stretched or compressed.

[0014] In the above scheme, the connector body and the generator can be clamped together by the clamping ring and the clamping block, thereby avoiding the problem of the connector body falling off due to vibration, and the clamping block can be pressed and contracted for easy disassembly and assembly, and after the outer cover layer is closed, the edge of the outer cover layer will be inserted into the closed groove of the clamping block, and the outer cover layer cannot move horizontally relative to the connector body under vibration, thereby achieving the purpose of horizontally limiting the clamping block, so that the clamping block will not move horizontally under vibration conditions, thereby avoiding the clamping block from falling off between the connector body and the generator due to vibration contraction, and the clamping spring extends half of the connecting groove when it is not stretched or compressed, which can ensure that the inward pulling force of the clamping spring when the outer cover layer is clamped into the connecting groove can apply a clamping force to the outer cover layer, thereby avoiding the outer cover layer from moving under vibration.

[0015] Preferably, the plug locking assembly includes a locking groove, a locking arm, a locking cam and a pre-tensioning spring; the locking groove is provided on the connector body; the locking arm is slidably installed in the locking groove; the locking cam is connected to the driving ratchet; and the pre-tensioning spring is connected between the locking arm and the locking groove.

[0016] In the above scheme, since the locking cam is connected to the driving ratchet, when the driving ratchet rotates, the locking cam will be driven to rotate. When the locking cam rotates, the locking arm will be displaced to increase the locking force on the plug, thereby utilizing vibration to drive the locking arm to lock, and the higher the vibration frequency, the better the locking effect.

[0017] Preferably, the locking groove is an oblique structure, and two locking grooves are symmetrically provided with a V-shaped structure with the tip facing the plug insertion direction; the inner surface of the locking arm is provided with a locking tooth surface.

[0018] In the above scheme, since the locking groove is an oblique structure, it can achieve a guiding effect on the locking arm, so that the force generated by the locking arm during movement can be decomposed into a clamping force on the plug and a force for inserting into the socket hole. The friction force generated by the clamping and the insertion force in the opposite direction of the loosening are used to cooperate with each other to achieve the purpose of preventing the plug from loosening, thereby further improving the anti-loosening effect. The friction between the locking tooth surface and the plug can be increased, and the pushing effect of the plug into the socket can be enhanced.

[0019] Preferably, the drainage mechanism includes a drainage groove, an articulated seat, a drainage piston and a connecting rod; the drainage groove is opened on the inner cover layer; the articulated seat is arranged on the surface of the connector body; the connecting rod is rotatably mounted on the articulated seat, and one end of the connecting rod is connected to the locking arm and the other end is connected to the drainage piston; the locking cam is an Archimedean cam structure.

[0020] In the above scheme, when the locking cam rotates, it will drive the locking arm to move in the horizontal direction, and the locking arm will drive the drainage piston to slide through the connecting rod, and will slowly push the locking arm to compress the plug in the lifting section of the locking cam, and will also slowly pull the drainage piston at this time. At this time, the movement of the drainage piston is an intake movement, and slow intake can avoid sucking in water. When the lifting section enters the return section, since the locking cam is an Archimedean cam, the drainage piston will move quickly during the drainage movement, which can quickly compress the air in the drainage groove outward to achieve the purpose of drainage.

[0021] Preferably, the connection position between the connecting rod and the locking arm is a movable connection that can slide back and forth; the distance between the articulated seat and the axis of the drainage piston is D, the distance between the articulated seat and the axis of the locking arm is S, and D is greater than S.

[0022] In the above scheme, the connection rod and the locking arm can slide back and forth at the connection position to ensure that no movement interference occurs when the locking arm moves obliquely, and the position of the hinged seat can realize short-distance displacement of the locking arm according to the lever principle, while the drainage piston can be displaced over a long distance, thereby increasing the volume of air compressed by the drainage piston during the drainage process.

[0023] Preferably, the drainage trough includes a spiral drainage section and a pressurized waterproof section; the spiral drainage section is connected to the inner cover layer, and the spiral drainage section is an opening structure spiraling downward; the pressurized waterproof section is arranged below the spiral drainage section, and the pressurized waterproof section is an hourglass-shaped structure.

[0024] In the above scheme, the compressed airflow can be made to flow downward in a swirling manner through the spiral drainage section, thereby enhancing the water discharge capacity and being able to drain water without dead angles. When there is no water, the wind pressure can also be used to prevent water from rising into the inner cover layer. The pressurized waterproof section uses the Venturi tube principle (the flow area is greatly reduced and then increased) to increase the flow rate during exhaust, and after passing through the position with a small flow area, the discharged airflow will be in the form of a diffuse jet, thereby enhancing the water discharge effect, and the hourglass-shaped structure itself can hinder the rising movement of water.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. Compared with the existing generator multifunctional connector, the present invention absorbs the vibration of the generator by vibrating the swing arm, and drives the driving ratchet to rotate by the vibrating swing arm, and utilizes the unidirectional rotation movement of the driving ratchet to realize the movement control of the locking arm and the drainage piston. When the driving ratchet rotates, it will drive the locking cam to rotate. When the locking cam is in the lifting section, it will drive the locking arm to clamp the plug along the oblique direction toward the plug insertion direction, and as the vibration frequency and vibration amplitude of the generator increase, the locking arm will dynamically increase the clamping thrust to ensure the locking effect of the plug, thereby preventing the plug from falling off due to the high-frequency vibration of the generator, and the main body locking assembly and the outer cover layer lock the connector body and the generator by mutual clamping, thereby ensuring that the connector body and the generator will not loosen.

[0027] 2. The present invention sets the locking cam as an Archimedean cam structure, which can ensure that the cam is in the lifting section when it rotates one circle from the starting point, and can ensure that the locking force is gradually increased during vibration. The relatively slow movement of this section will drive the drainage piston to perform a slow reset movement. The slow reset of the drainage piston will slowly inhale air, and the slow inhalation can avoid water being sucked into the inner cover layer. During the switching process of the lifting section and the return section, due to the fast switching speed, the drainage piston can be guaranteed to move quickly, and the air in the drainage groove can be quickly compressed outward to achieve the purpose of drainage, thereby improving the waterproof effect.

[0028] 3. The present invention designs the drainage trough as a combination of a spiral drainage section and a pressurized waterproof section, so that the air compressed by the drainage piston can flow downward in a swirling manner, ensuring that the air can be compressed in areas prone to water seepage without dead ends, thereby ensuring that the water retained in this position can be discharged, and when there is no water, the wind pressure can also be used to prevent the water from rising into the inner cover layer. The pressurized waterproof section uses the Venturi tube principle to increase the flow rate during exhaust when the flow area changes from large to small, and will make the exhausted airflow in a diffuse jet shape when the flow area changes from small to large, thereby enhancing the water discharge effect, and the hourglass-shaped structure itself can hinder the rising movement of water, thereby improving the waterproof effect.

DETAILED DESCRIPTION

[0039] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] See also Figures 1 to 8 The present invention provides a multifunctional waterproof and anti-detachment connector for a generator, and the technical solution is as follows:

[0041] As a specific embodiment of the present invention, refer to Figure 1 , Figure 2 and Figure 3; A multifunctional waterproof and anti-detachment connector for a generator, which is plugged into a generator 1 and includes a connector body 2 and a waterproof cover 3; it also includes a driving mechanism 4, a locking mechanism 5 and a drainage mechanism 6; the waterproof cover 3 includes an inner cover layer 31 and an outer cover layer 32; the inner cover layer 31 is connected to the front of the connector body 2; the outer cover layer 32 is rotatably mounted on the connector body 2; the driving mechanism 4 is connected to the connector body 2, and when the generator 1 vibrates, the driving mechanism 4 absorbs the vibration and performs unidirectional rotational movement; the locking mechanism 5 includes a main body locking assembly 51 and a plug locking assembly 52; the main body locking assembly 51 is connected to the back of the connector body 2; the plug locking assembly 52 is connected to the front of the connector body 2, and the driving mechanism 4 rotates to drive the plug locking assembly 52 to perform oblique telescopic movement; the drainage mechanism 6 is connected to the plug locking assembly 52, and when the plug locking assembly 52 performs oblique telescopic movement, it drives the drainage mechanism 6 to move in the opposite horizontal direction.

[0042] As a specific embodiment of the present invention, refer to Figure 3 ; A mounting groove 21 is provided in the connector body 2; the driving mechanism 4 includes a vibrating swing arm 41, a driving ratchet 42 and a pull-back spring 43; the vibrating swing arm 41 is rotatably mounted in the mounting groove 21; the driving ratchet 42 is mounted in the mounting groove 21 and cooperates with the vibrating swing arm 41; one end of the pull-back spring 43 is connected to the vibrating swing arm 41, and the other end is connected to the mounting groove 21. At this time, the vibration swing arm 41 is similar to a cantilever beam structure, so the vibration generated when the generator 1 is working can be absorbed by the vibration swing arm 41, so as to achieve the purpose of using the vibration swing arm 41 to drive the driving ratchet 42 to rotate, and when the driving ratchet 42 rotates, it will drive the plug locking assembly 52 and the drainage mechanism 6 to work, and the reset force of the pull-back spring 43 can help the vibration swing arm 41 to reset, so as to swing the next time, and the driving ratchet 42 can achieve unidirectional rotation, so as to achieve unidirectional driving of the plug locking assembly 52 and the drainage mechanism 6, so as to avoid the drainage mechanism 6 causing the water flow to flow in a disorderly manner, and achieve the purpose of using the high-frequency vibration of the generator 1 itself to achieve the purpose of rapid drainage, so that the water entering the outer cover layer 32 can be discharged and avoid entering the inner cover layer 31. The non-hinged end of the vibration swing arm 41 is provided with a counterweight 411. The counterweight 411 can make the vibration amplitude of the vibration swing arm 41 larger when the generator 1 vibrates, and can increase the driving force generated when the vibration swing arm 41 vibrates, so as to enhance the driving effect.

[0043] As a specific embodiment of the present invention, refer to Figure 2 and Figure 4; The main body locking assembly 51 includes a snap ring 511, a snap groove 512, a snap block 513 and a snap spring 514; the snap ring 511 is arranged on the back side of the connector body 2; the snap groove 512 is provided in the snap ring 511; the snap block 513 is slidably installed in the snap groove 512, and a connecting groove 5131 is provided on the snap block 513; the snap spring 514 is connected between the snap block 513 and the snap groove 512, and the connecting groove 5131 extends out half of the snap groove 512 when the snap spring 514 is not stretched or compressed. The connector body 2 and the generator 1 can be clamped together by the clamping ring 511 and the clamping block 513, thereby avoiding the problem of the connector body 2 falling off due to vibration, and the clamping block 513 can be pressed and contracted for easy disassembly and assembly, and after the outer cover layer 32 is closed, the edge of the outer cover layer 32 will be inserted into the closed groove of the clamping block 513, and the outer cover layer 32 cannot move horizontally relative to the connector body 2 under vibration, thereby achieving the purpose of horizontally limiting the clamping block 513, so that the clamping block 513 will not move horizontally under vibration conditions, thereby avoiding the clamping block 513 from falling off between the connector body 2 and the generator 1 due to vibration contraction, and the clamping spring 514 extends half of the connecting groove 5131 when it is not stretched or compressed, which can ensure that when the outer cover layer 32 is clamped into the connecting groove 5131, the inward pulling force of the clamping spring 514 can apply a clamping force to the outer cover layer 32, thereby avoiding the outer cover layer 32 from moving under vibration.

[0044] As a specific embodiment of the present invention, refer to Figure 3 , Figure 5 and Figure 6 The plug locking assembly 52 includes a locking groove 521, a locking arm 522, a locking cam 523 and a preload spring 524. The locking groove 521 is provided on the connector body 2. The locking arm 522 is slidably mounted in the locking groove 521. The locking cam 523 is connected to the driving ratchet 42. The preload spring 524 is connected between the locking arm 522 and the locking groove 521. Since the locking cam 523 is connected to the driving ratchet 42, when the driving ratchet 42 rotates, the locking cam 523 will be driven to rotate. When the locking cam 523 rotates, the locking arm 522 will be displaced to increase the locking force on the plug, thereby realizing the use of vibration to drive the locking arm 522 to lock, and the higher the vibration frequency, the better the locking effect. Moreover, the locking arm 522 can still be pressed against the plug at the lowest position of the lifting section of the locking cam 523.

[0045] As a specific embodiment of the present invention, refer to Figure 5; The locking groove 521 is an oblique structure, and the locking groove 521 is symmetrically provided with two V-shaped structure tips facing the plug insertion direction; the inner surface of the locking arm 522 is provided with a locking tooth surface 5221; Since the locking groove 521 is an oblique structure, it can achieve a guiding effect on the locking arm 522, so that the force generated by the locking arm 522 during movement can be decomposed into a clamping force on the plug and a force for inserting into the socket hole, and the friction force generated by the clamping and the insertion force opposite to the loosening direction are used to cooperate to achieve the purpose of preventing the plug from loosening, and further improve the anti-loosening effect; the friction between the plug and the locking tooth surface 5221 can be increased, and the pushing effect of the plug into the socket can be enhanced. The locking tooth surface 5221 can be set to a nano-scale tooth surface. During the locking process, the locking tooth surface 5221 can be embedded in the surface of the plug, thereby enhancing the clamping effect and not causing damage to the internal structure of the plug.

[0046] As a specific embodiment of the present invention, refer to Figure 6 and Figure 7 The drainage mechanism 6 includes a drainage groove 61, an articulated seat 62, a drainage piston 63 and a connecting rod 64; the drainage groove 61 is provided on the inner cover layer 31; the articulated seat 62 is provided on the surface of the connector body 2; the connecting rod 64 is rotatably mounted on the articulated seat 62, and one end of the connecting rod 64 is connected to the locking arm 522 and the other end is connected to the drainage piston 63; the locking cam 523 is an Archimedean cam structure. When the locking cam 523 rotates, it will drive the locking arm 522 to move in the horizontal direction, and the locking arm 522 will drive the drainage piston 63 to slide through the connecting rod 64, and will slowly push the locking arm 522 to compress the plug during the lifting section of the locking cam 523, and will also slowly pull the drainage piston 63 at this time. At this time, the movement of the drainage piston 63 is an air intake movement, and the slow air intake can avoid the intake of water. When the lifting section enters the return section, since the locking cam 523 is an Archimedean cam, the drainage piston 63 will move quickly during the drainage movement, which can quickly compress the air in the drainage groove 61 outward to achieve the purpose of drainage.

[0047] As a specific embodiment of the present invention, refer to Figure 6 , Figure 7 and Figure 8; The connection position between the connecting rod 64 and the locking arm 522 is a movable connection that can slide back and forth, and the groove on the connecting rod 64 that is connected to the locking arm 522 can cooperate with the rotational movement of the connecting rod 64 to avoid movement interference. The connection position between the connecting rod 64 and the drain piston 63 also allows the connecting rod 64 to slide up and down relative to the drain piston 63; the distance between the articulated seat 62 and the axis of the drain piston 63 is D, and the distance between the articulated seat 62 and the axis of the locking arm 522 is S, and D is greater than S. The connection position between the connecting rod 64 and the locking arm 522 can slide back and forth to ensure that no movement interference occurs when the locking arm 522 moves obliquely. The position of the hinged seat 62 can realize a short-distance displacement of the locking arm 522 according to the lever principle, while the drain piston 63 can be displaced over a long distance, thereby increasing the volume of air compressed by the drain piston 63 during the drainage process. The position of the hinged seat 62 can be adjusted according to the specific size, so that the distance D between the hinged seat 62 and the axis of the drain piston 63 is proportional to the distance S between the hinged seat 62 and the axis of the locking arm 522, thereby balancing the compression effect and the exhaust effect.

[0048] As a specific embodiment of the present invention, refer to Figure 7 The drainage groove 61 includes a spiral drainage section 611 and a pressurized waterproof section 612; the spiral drainage section 611 is connected to the inner cover layer 31, and a spiral downward opening structure is provided on the spiral drainage section 611, and the opening is in the middle of the inner wall of the spiral drainage section 611, so as to ensure that the compressed gas can still swirl along the inner wall of the spiral drainage section 611; the pressurized waterproof section 612 is arranged below the spiral drainage section 611, and the pressurized waterproof section 612 is an hourglass-shaped structure. The compressed airflow can be swirled downward through the spiral drainage section 611, thereby enhancing the water discharge capacity, and can drain water without dead angles, and can prevent water from rising into the inner cover layer 31 through wind pressure when there is no water; and the pressurized waterproof section 612 uses the Venturi tube principle to increase the flow rate during exhaust, and after passing through the small flow area position, the discharged airflow will be in a diffuse jet shape, thereby enhancing the water discharge effect, and the hourglass-shaped structure itself can achieve an obstructive effect on the rising movement of water.

[0049] Working process: press the engaging block 513, insert the connector body 2 into the generator 1, release the engaging block 513, after the engaging block 513 is engaged with the generator 1, insert the plug into the socket on the surface of the connector body 2, and then rotate the outer cover layer 32 and engage it into the connecting groove 5131. When the generator 1 vibrates during operation, the vibrating swing arm 41 swings to drive the driving ratchet 42 to rotate in one direction, and provides power to the plug locking assembly 52 and the drainage mechanism 6 through the driving ratchet 42, so that the locking arm 522 dynamically locks the plug inserted into the socket, and the drainage piston 63 will press out the water that reaches the part prone to water seepage through the exhaust movement, thereby improving the waterproof effect.

[0050] Specifically, press the engaging block 513, insert the connector body 2 onto the generator 1, release the engaging block 513, and after the engaging block 513 is engaged with the generator 1, insert the plug into the socket on the surface of the connector body 2, and then rotate the outer cover layer 32 and engage it into the connecting groove 5131. At this time, the connection is completed and the generator 1 can be started to work; when the generator 1 vibrates during operation, the vibrating swing arm 41 is a cantilever beam structure and a counterweight block 411 is not fixed at one end. When the generator 1 vibrates, the vibrating swing arm 41 will swing, thereby driving the driving ratchet 42 to rotate unidirectionally. When the driving ratchet 42 rotates unidirectionally, it will drive the locking cam 523 to rotate, and when the locking cam 523 rotates in the lifting section, it will push the locking arm 522 to squeeze the plug obliquely, thereby preventing the plug from loosening, and in this process The middle connecting rod 64 will drive the drainage piston 63 to perform a reset action, and in this process, the movement of the drainage piston 63 is slow, thereby ensuring that the drainage piston 63 will not suck water into the inner cover layer 31 when performing the reset action; when the locking cam 523 switches from the lift section to the return section, it will quickly drive the drainage piston 63 to perform an exhaust action. In this process, the drainage piston 63 will discharge the gas from the spiral drainage section 611. At this time, the gas will form a downward vortex motion, thereby draining water without dead ends, and when there is no water, the wind pressure can also prevent water from rising into the inner cover layer 31. The flow area of ​​the pressurized waterproof section 612 is from large to small and then to large. On the one hand, the structure can prevent water from penetrating, and on the other hand, the discharged airflow can be in the form of a diffuse jet, thereby enhancing the barrier effect against water and preventing water from penetrating into the inner cover layer 31.
