DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] Please refer to the attached Figure 1-3 , an embodiment of the present application provides a sealing locking cover, which can be installed on the device body of a mechanical device (including containers and mechanical devices such as boxes, vehicles, etc.), and can be used to seal and cover the opening of a cavity for containing liquid on the device body, such as a fuel tank opening. The sealing locking cover includes an end cover 6 and a lock body assembly. The end cover 6 and the device body can be connected in an openable and closable manner, such as by a threaded connection or by a connecting piece such as a hinge shaft or a hinge, and can also be slidably connected by a sliding structure, for sealing or opening the opening of the cavity. At the same time, a first sealing member 5 is provided on the inner side of the end cover 6 that contacts the device body, so that the opening of the cavity can be sealed and covered, ensuring the sealing of the cavity, and having good dustproof and waterproof properties.

[0033] The lock body assembly includes a lock body and a dedicated unlocking piece. The lock body is connected and fixed to the end cover 6, and can be locked with the device body to lock the end cover 6. The dedicated unlocking piece is used to release the locking function of the lock body to unlock the end cover 6. The lock body is fixed to the end cover 6. When the lock connection between the lock body and the device body is released by a dedicated unlocking piece such as a key or a password input piece, the end cover 6 can be opened, and the lock body moves with the end cover 6 to reveal the cavity opening of the cavity without covering the cavity opening; when locking is required, the end cover 6 returns to cover the cavity opening, and the lock body also moves with the end cover 6 to a position where it can be locked, and then locking can be performed, locking the end cover 6, so that people who do not have the dedicated unlocking piece cannot open it.

[0034] For example Figure 1As shown, the cavity opening of the cavity is in the shape of a tube body 3, or in other words, a tube body 3 is provided, and the tube opening of the tube body 3 is the cavity opening of the cavity. The end cover 6 can be threadedly connected to the tube body 3, and the lock body is fixed on the end cover 6. When the end cover 6 is connected to the device body to cover the cavity opening, the lock body extends into the tube body 3. When unlocking, the lock body is pulled out of the tube body 3 with the movement of the end cover 6. Of course, the end cover 6 can also be rotatably connected to the device body through a hinge or other connecting parts. The length of the lock body extending into the cavity needs to be small, and the structural setting of moving out of the cavity opening with the rotation of the end cover 6 can be satisfied. Alternatively, the end cover 6 is slidably connected to the device body through a sliding structure, and the lock body is located outside the cavity opening of the cavity. A lock seat can be protruded on one side of the cavity opening, and a lock groove is provided on the lock seat. The end cover 6 slides along the radial direction of the cavity opening, away from or close to the lock seat, to close or open the cover. With such arrangement, after the cavity opening is sealed with the end cover 6, the lock body and the device body are locked and connected, so that the end cover 6 can be locked or locked, and the end cover 6 cannot be opened without using a dedicated unlocking piece to unlock it; and when the end cover 6 needs to be opened to expose the cavity opening of the cavity, the lock body and the device body are separated by using a dedicated unlocking piece to unlock it, thereby releasing the locking / locking effect on the end cover 6, and the end cover 6 can be opened to expose the cavity opening of the cavity, so as to perform operations such as fluid replenishment.

[0035] It can be seen that the sealed locking cover provided by the present application can not only seal the cavity opening of the cavity to prevent impurities from entering and has dust and water proof effects, but also can lock the cover on the device body through the setting of the lock body. It can only be opened by using a dedicated unlocking component such as a remote control switch or a key or a password input component, which effectively prevents other people from maliciously opening the cover or performing malicious damage, and can also prevent the cover from accidentally loosening and falling, causing safety hazards such as contamination or leakage of the liquid in the cavity, significantly improving the protection effect and safety performance, and is particularly suitable for engineering machinery such as automobiles or vehicles, such as the cover of the fuel tank opening.

[0036] Specifically, the first sealing member 5 may be a sealing ring or a sealing gasket. Figure 1 As shown, if the cavity opening is in the shape of a tube body 3, and the end cover 6 is covered on the tube body 3, the end cover 6 is in the shape of a cap, which can be threadedly connected to the tube body 3, and the first sealing member 5 can be a sealing ring, which is embedded on the inner side surface of the end cover 6 where the thread is set. When the end cover 6 is screwed onto the cover body, the first sealing member 5 is squeezed to seal the connection between the end cover 6 and the tube body 3.

[0037] The lock body assembly can be any one of a password lock, a mortise lock or a remote control lock. For example, the lock body can be provided with a password lock structure, a mortise lock structure or a remote control lock structure. The password lock structure refers to a structure provided on the lock body for locking or unlocking by a password. The mortise lock structure refers to a lock body provided with a lock core 8 that cooperates with a key, and the key is inserted into the lock body and acts on the lock core 8 to lock or unlock. The remote control lock structure refers to a lock tongue 2 on the lock body that is controlled to extend and retract by a remote control switch to lock or unlock, such as an electromagnetic lock, or a lock in which the lock tongue 2 is controlled by a power part such as a motor, and the power part is controlled by a remote control switch. The exclusive unlocking part is a part that releases the lock body locking connection, such as a password input part, a remote control switch or a key. The lock body can only be unlocked under the action of the exclusive unlocking part.

[0038] When the lock body is provided with a password lock structure, the password lock structure may be an electronic password lock structure, such as including a processor and a power member that drives the lock tongue of the lock body to move, and the exclusive unlocking member is a password input member such as a password input screen / password input button. The correct password is input through the password input member, and after the processor receives the correct password signal, it will start the power member to retract the lock tongue 2 so that the lock body and the device body are separated, and the end cover 6 can be unlocked, and then the end cover 6 can be opened to reveal the cavity. The locking signal is input through the password input member or the end cover is returned to the locking position to generate a locking signal. After receiving the locking signal, the processing area starts the power member to extend the lock tongue 2 into the lock slot of the device body and lock the end cover 6. Alternatively, the password lock structure may be a mechanical password lock structure, such as including a rotating shaft, a lock tongue 2, etc., and the exclusive unlocking member is a password wheel set that is sleeved on the rotating shaft and connected to the rotating shaft, and the extension and retraction of the lock tongue 2 is controlled by the password wheel set.

[0039] When the lock body is provided with a mortise lock structure, the exclusive unlocking part is a key. When the lock body is provided with a remote control lock structure, the exclusive unlocking part can be a remote control switch.

[0040] The present application also provides a specific embodiment in which the lock body is provided with a mortise lock structure, and its specific structure is different from the mortise lock in the prior art.

[0041] The lock body assembly includes a lock body and a dedicated unlocking member such as a key that can be separated from the lock body. The lock body includes a base 11, a lock tongue 2, a lock core 8, and a reset member 1 that drives the lock tongue 2 to reset. Figure 1 The lock tongue 2, lock core 8 and reset member 1 are all fixed on the base 11, and the base 11 is connected to the end cover 6, so that the entire lock body is fixed on the end cover 6. When the lock tongue 2 is retracted and separated from the device body and is in the unlocked state, the end cover 6 is opened, and the lock body moves with the end cover 6 to reveal the covered cavity.

[0042] The locking tongue 2 is arranged on the base 11 and is telescopically arranged relative to the base 11 so as to be inserted into or removed from the device body.

[0043] The lock core 8 is rotatably arranged on the base 11, and is provided with a structure 18 for pushing the lock tongue 2. After the exclusive unlocking piece is inserted into the lock core 8 or connected to the lock core 8, it drives the lock core 8 to rotate so that the structure 18 pushes the lock tongue 2 into the device body to achieve locking. After locking, the exclusive unlocking piece and the lock core 8 are separated, and the lock core 8 is maintained in the locked position, pushing the lock tongue 2 to ensure a stable locked state. When unlocking is required, the exclusive unlocking piece drives the lock core 8 to reverse, and the structure 18 no longer pushes the lock tongue 2 and rotates back to the initial position, and the lock tongue 2 retracts and resets under the drive of the reset piece 1, and is separated from the device body to achieve unlocking.

[0044] With such arrangement, the lock tongue 2 can be stably extended and retracted, quickly retracted and has a simple structure. Only a structure 18 that can push the lock tongue 2 as it rotates needs to be arranged on the lock core 8, and the lock tongue 2 can be automatically reset with only a reset member 1. The structure of the entire lock body is simple and easy to arrange, which is beneficial to reducing production costs, and the simple structure is convenient for maintenance.

[0045] The locking tongue 2 can be directly connected to the base 11, or the base 11 is provided with a connecting seat 17, and the locking tongue 2 is arranged on the connecting seat 17, for example Figure 1 As shown, the connecting seat 17 is provided with a through hole arranged along the radial direction of the lock core 8, the lock tongue 2 is located in the through hole, and the reset member 1 can be a spring, which can be arranged in the through hole and between the connecting seat 17 and the lock tongue 2.

[0046] The structure 18 on the lock core 8 may be a cam structure, having an outer arc surface for pushing the lock tongue 2, and the distance between the outer arc surface and the rotation center line is greater than the distance between other wheel surface areas and the rotation center line, or in other words, the diameter of the outer arc surface is greater than the diameter of other wheel surface areas. When the structure 18 rotates with the lock core 8 until the outer arc surface pushes the lock tongue 2, the lock tongue 2 can be pushed out of the lock body and inserted into the device body, such as Figure 3 When the outer arc surface moves away, the lock tongue 2 retracts and resets under the action of the spring.

[0047] The lock body can be detachably connected to the end cover 6. If a connection hole is provided on the end cover 6, the lock body is inserted into the connection hole for fixing, and can be threadedly connected to the end cover 6, or connected by fasteners such as screws. Or, in some embodiments, such as Figure 1 As shown, the connection seat 17 is detachably connected to the base 11, the lock body is inserted into the connection hole and is provided with a boss that abuts against the end cover 6, the connection seat 17 and the boss clamp the end cover 6 on both sides of the end cover 6 to detachably fix the lock body to the end cover 6. The connection seat 17 and the base 11 can be threaded or connected by fasteners such as screws. In this way, the lock tongue 2 and the reset member 1 are arranged on the connection seat 17, and the connection seat 17 is detachably connected to the base 11, and cooperates with the boss on the base 11 to detachably fix the base 11 to the end cover 6, which is not only convenient for split processing, but also convenient for assembly, and also convenient for maintenance and replacement of parts in the later stage.

[0048] The lock body is detachably connected to the end cover 6. To enhance the overall sealing of the end cover 6, in some embodiments, a second seal 7 is provided between the lock body and the end cover 6. The second seal 7 is used to seal the connection and ensure the sealing of the end cover 6 to the cavity.

[0049] like Figure 1 As shown, the second sealing member 7 may be an annular sealing gasket, which is disposed between the boss on the base 11 and the end cover 6 to seal the insertion point between the base 11 and the end cover 6 .

[0050] As the ambient temperature changes, the pressure in the cavity will change. To prevent the pressure in the cavity from being too high and affecting the use or causing danger, a one-way exhaust valve is also provided on the end cover 6. The one-way exhaust valve is a one-way valve structure, which only allows gas to be discharged from the cavity to the outside, and does not allow external gas to enter. In this way, when the pressure in the cavity is high, the gas can be exhausted to the outside to relieve the pressure, thereby ensuring the safety of the cavity, and the sealing of the cavity can be ensured, so that it will not communicate with the outside.

[0051] like Figure 2 As shown, the valve body of the one-way exhaust valve is inserted into the end cover 6, the valve hole is connected to the cavity, and the valve core of the exhaust valve is installed in the valve hole. In some embodiments, the valve hole of the one-way exhaust valve is not a straight hole structure, and the valve hole includes a mounting hole section near the exhaust hole and a flared hole section near the inside of the cavity. The flared hole section is an flared hole structure, and the aperture of the section gradually increases along the gas outlet direction. The valve core of the exhaust valve includes a ball 16 and an elastic member 15. The elastic member 15 is arranged in the mounting hole section, one end of which is against the part at the exhaust hole, and the other end presses the ball 16, pressing the ball 16 in the flared hole section and blocking the hole of the flared hole section to achieve the blocking of the valve block. When the pressure in the cavity is too high, the ball 16 will be pushed upward, so that the flared hole section is opened, and the gas can leak out. When the pressure in the cavity is weakened, the ball 16 will re-block the flared hole section under the action of the elastic member 15 to ensure the one-way exhaust performance.

[0052] In some embodiments, a sealing gasket 14 covering the exhaust port is provided at the exhaust port of the valve hole, such as Figure 2As shown, a retaining ring 13 or a convex edge is provided at the exhaust port of the valve hole, and the inner hole of the retaining ring 13 or the convex edge forms the exhaust port of the one-way exhaust valve, and a sealing gasket 14 is laid on the inner side of the retaining ring 13 or the convex edge. One end of the spring presses the sealing gasket against the retaining ring 13 or the convex edge to fix the sealing gasket 14, and the other end presses the ball 16 against the expansion section. A plurality of air holes are distributed on the sealing gasket 14, such as having a microporous structure, so that it has air permeability, such as a sponge pad. Such an arrangement can enhance the sealing covering of the exhaust port of the valve hole, and prevent dust and other impurities from entering the cavity from the valve hole and contaminating the liquid in the cavity. For engineering machinery, there are many impurities such as dust in the working environment, and the oil in the oil tank needs to be kept clean. The sealing locking cover provided by the present application is very suitable for being set on engineering machinery, and has both firm sealing and stable connection, and high sealing and dustproof performance.

[0053] In some other embodiments, in order to prevent dust and other impurities from entering the cavity, the sealed locking cover is also provided with a dust cover 9 for covering the end cover 6. The dust cover 9 is connected to the end cover 6 in an openable and closable manner, for example, by threaded connection, rotational connection through a hinge shaft, or sliding connection through a sliding structure, at least covering the lock body, and when a one-way exhaust hole is provided on the end cover 6, the exhaust port of the one-way exhaust hole can also be covered. At the same time, the area on the dust cover 9 for covering the exhaust port has a breathable structure or is provided with a breathable member, which can ensure the smoothness of exhaust. In this way, without affecting the normal use of locking and exhaust, the sealing of the connection between the lock body and the end cover 6, the dust protection of the lock body, and the dust protection of the exhaust port can be enhanced, and impurities can be effectively prevented from entering the cavity or blocking the lock core 8 and the exhaust valve hole, thereby improving protection and safety.

[0054] like Figure 2 As shown, a first breathable cover pad 12 is provided at a position corresponding to the exhaust port on the inner side of the dust cover 9, and the first breathable cover pad 12 has air holes, such as a microporous structure. In this way, after the dust cover 9 is closed, the exhaust performance of the one-way exhaust valve will not be affected, and dust and other impurities can be effectively prevented from entering the valve hole to block the valve hole or pollute the oil in the cavity.

[0055] Similarly, a second breathable cover pad 10 may also be provided on the inner side of the dust cover 9 at a position corresponding to the lock core 8 , and the second breathable cover pad 10 has breathable holes, such as a microporous structure.

[0056] like Figure 1 As shown, in some embodiments, a sealing sleeve assembly 4 is sleeved on the section of the lock body protruding from the inner side of the end cover 6 and located in the cavity, so as to enhance the sealing of the cavity opening and also enhance the protection of the lock body.

[0057] The sealing sleeve assembly 4 includes an inner sleeve and a rubber sleeve sleeved outside the inner sleeve, and the inner sleeve can be a rigid member. The connecting seat 17 on the base 11 for fixing the locking tongue 2 at least partially protrudes radially from the base 11, and the protruding part resists the sealing sleeve assembly 4, fixes the sealing sleeve assembly 4 between the connecting seat 17 and the end cover 6, and prevents the sealing sleeve assembly 4 from sliding off the base 11.

[0058] The embodiment of the present application further provides a mechanical device, which includes a device body, a cavity is provided on the device body, and a sealing and locking cover is provided on the cavity opening of the cavity, and the sealing and locking cover is the sealing and locking cover as described in any of the above embodiments. Then the cavity on the mechanical device has high sealing performance, high locking performance, high dust and water resistance, high protection performance, and high safety performance. The derivation process of its beneficial effects is basically the same as the derivation process of the beneficial effects of the sealing and locking cover in the above embodiments, and will not be repeated here.

[0059] In some specific embodiments, the cavity on the device body of the mechanical equipment is used to hold oil, and a tube body 3 is provided at the cavity opening of the cavity, a sealing lock cover is provided on the tube body 3, the lock body extends into the tube body 3, and an annular lock groove extending in the circumferential direction is provided on the tube wall of the tube body 3. Figure 1 As shown, the end cap 6 can be threadedly connected to the tube body 3, the section of the lock body protruding from the inner side of the end cap 6 extends into the tube body 3, and the sealing sleeve assembly 4 is located between the inner wall of the tube body 3 and the base 11, thereby enhancing the sealing performance of the cavity opening. At the same time, there is an exhaust passage between the sealing sleeve assembly 4 and the inner wall of the tube body 3, which is connected to the one-way vent valve, to ensure smooth exhaust and pressure relief.

[0060] Specifically, a spiral through groove can be provided on the rubber sleeve of the sealing sleeve assembly 4. In this way, when the sealing locking cover is connected to the tube body 3 and the space between the lock body and the tube body 3 is blocked by the sealing sleeve assembly 4, the spiral through groove forms the above-mentioned exhaust channel, ensuring that the gas in the cavity can flow from the exhaust channel to the one-way exhaust valve to leak out, thereby ensuring that the pressure in the cavity is stable and safe.
