Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a magnetic valve lock structure. Background Technology

[0002] A magnetic locking valve is a safety device specifically designed to prevent valves from being opened and closed arbitrarily. It is widely used in pipeline systems in industries such as heating, water supply, and gas supply, controlling the opening and closing of the valve through magnetic force. The valve cap and cover of a magnetic locking valve are locked by a magnet. In use, the key is engaged with the valve cap. The upper unlocking magnet in the key and the lower unlocking magnet between the valve cap and cover repel each other magnetically. This repulsive force causes the lower unlocking magnet to exert pressure on a spring, fully retracting into the lower locking hole of the valve cover. This allows the upper valve cover to rotate with the key, which in turn rotates the valve stem, thus opening and closing the valve.

[0003] To enhance the security of magnetic lock valves, existing designs have added combination locks to them. However, combination locks are complex in structure and inconvenient to manufacture, which hinders their widespread use. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to provide a magnetic valve lock structure.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] The lock includes a lock body, a key, an unlocking component, a valve stem, and a valve cover. The lock body has an operating hole and a sliding cavity formed therein, the operating hole communicating with the sliding cavity. The key is disposed in the sliding cavity. The valve cover abuts against the lock body and the valve stem. The valve stem passes through the valve cover and is rotatably connected to the lock body, with a portion of the valve stem located within the sliding cavity. A locking assembly is disposed between the key and the bottom of the sliding cavity. A first unlocking magnet is disposed on the unlocking component. The key has an unlocking groove, and the unlocking component can be inserted into the unlocking groove through the operating hole.

[0007] When the magnetic valve lock structure is in the locked state, the unlocking member disengages from the unlocking groove, and the locking assembly locks the key at the position of the sliding cavity; when the magnetic valve lock structure is in the unlocked state, the unlocking member is located in the unlocking groove, and the first unlocking magnet releases the locking assembly from locking the key, so that the key can slide along the length direction of the sliding cavity, and the key can slide to the position where it engages with the valve stem.

[0008] It is understandable that by locking or unlocking the key through the unlocking mechanism, the security of the magnetic valve lock structure can be guaranteed without the need for an additional combination lock. The structure is simple, easy to process and manufacture, and conducive to its widespread use.

[0009] In one embodiment, the locking assembly includes a spring and a locking pin, the locking pin being connected to the spring. When the magnetic valve lock structure is in the locked state, the locking pin can abut against the key to limit the key; when the magnetic valve lock structure is in the unlocked state, the locking pin can retract under the action of the first unlocking magnet and compress the spring.

[0010] In one embodiment, the unlocking member is provided with a protruding post, and when the unlocking member is located in the unlocking groove, the protruding post extends out of the operating hole.

[0011] Understandably, this design makes it easier for users to push the unlocking mechanism with the protruding post, thus making it more convenient to use.

[0012] In one embodiment, a limiting groove is formed on the key, and a limiting post is formed on the valve stem. The groove wall of the limiting groove can form a limiting engagement with the outer wall of the limiting post, so that the key can drive the valve stem to rotate.

[0013] In one embodiment, a first protrusion and a concave block are formed on the unlocking member, and a second protrusion and a concave block are formed on the bottom of the unlocking groove. The first protrusion and the second protrusion and a concave block are correspondingly arranged so that the unlocking member can abut against the bottom of the unlocking groove.

[0014] Understandably, this design makes it difficult for others to imitate the unlocking mechanism, thus improving the safety and reliability of the magnetic valve lock structure.

[0015] In one embodiment, the magnetic valve lock structure further includes a valve cap, which is disposed on the valve cover. The key is provided with a second unlocking magnet, and a third unlocking magnet is disposed between the valve cover and the valve cap. When the key and the valve stem form a limiting engagement, the third unlocking magnet can generate a repulsive force under the action of the second unlocking magnet, thereby unlocking the valve cover from the valve cap.

[0016] Understandably, the combination of the second and third unlocking magnets creates a dual unlocking mechanism, enhancing security.

[0017] In one embodiment, the lock body has a sealing opening on its side, and the sealing opening communicates with the sliding cavity.

[0018] Understandably, during installation, the key enters the sliding cavity from the seal, making key installation more convenient.

[0019] In one embodiment, a cap is provided at the location of the seal to block the seal.

[0020] In one embodiment, the lock body is further provided with a rotating connection hole, and one end of the valve stem is rotatably connected to the lock body through a connector passing through the rotating connection hole.

[0021] In one embodiment, a seal is provided between the valve stem and the valve cover to form a seal between the valve stem and the valve cover.

[0022] It is understandable that a seal is installed to prevent the medium from seeping in and damaging the magnetic structure.

[0023] The advantages of this utility model:

[0024] This utility model claims a magnetic valve lock structure that, by locking or unlocking the movement of the key through an unlocking component, ensures the security of the magnetic valve lock structure without the need for an additional combination lock. The structure is simple, easy to process and manufacture, and conducive to its widespread use. Attached Figure Description

[0037] Please see Figures 1 to 5 A magnetic valve lock structure 100 provided in one embodiment of the present invention includes a lock head body 10, a valve cover 50, a valve stem 40, a key 20, and an unlocking component 30. The lock head body 10 has a sliding cavity 11 formed inward, and the lock head body 10 also has an operation hole 12, which communicates with the sliding cavity 11. The valve stem 40 passes through the valve cover 50 and is rotatably connected to the lock head body 10, with a portion of the valve stem 40 located inside the sliding cavity 11. The key 20 is limited to the sliding cavity 11, and the key 20 has an unlocking groove 21. A locking component (not shown) is provided between the key 20 and the bottom of the sliding cavity 11. The key 20 can slide along the length direction of the sliding cavity 11 and can be locked by the locking component. The unlocking component 30 is provided with a first unlocking magnet (not shown).

[0038] like Figure 1 As shown, when the magnetic valve lock structure 100 is in the locked state, the unlocking member 30 disengages from the unlocking groove 21, and the locking component locks the key 20 in the position of the sliding cavity 11. At this time, the key 20 is stuck by the locking component and cannot be pushed. The key 20 is separated from the valve stem 40, and the lock head body 10 can rotate freely around the valve stem 40.

[0039] like Figure 3 and Figure 4 As shown, when the magnetic valve lock structure 100 is in the unlocked state, the unlocking component 30 is located in the unlocking groove 21. The first unlocking magnet releases the locking component from the key 20, so that the key 20 can slide along the length direction of the sliding cavity 11, and the key 20 can slide to the position where it engages with the valve stem 40. After the key 20 and the valve stem 40 form a limit, the lock head body 10 no longer spins freely. The valve stem 40 can be turned by rotating the lock head body 10, thereby opening the valve.

[0040] Thus, by locking the key 30 or moving the key 20, the security of the magnetic valve lock structure can be guaranteed without setting an additional combination lock. The structure is simple, easy to process and manufacture, and conducive to its widespread use.

[0041] In one embodiment, the locking assembly includes a spring and a locking pin. The locking pin is connected to the spring and can abut against the key 20 to limit the key 20. The locking pin can also retract and compress the spring under the drive of the first unlocking magnet, thereby locking the key within the sliding cavity. The locking assembly is located at the bottom of the sliding cavity 11.

[0042] In one embodiment, the unlocking member 30 is provided with a protrusion 31. When the unlocking member 30 is located in the unlocking groove 21, the protrusion 31 extends out of the operating hole 12. This arrangement makes it easier for the user to push the unlocking member 30 through the protrusion 31, thus making it more convenient to use. The user pushes the unlocking member 30 to move through the protrusion 31, thereby pushing the key 20 to slide in the sliding cavity 11. The lock body 10 is also provided with a sliding groove 13, which is connected and communicates with the operating hole 12. The protrusion 31 can slide and engage with the groove wall of the sliding groove 13.

[0043] In one embodiment, a limiting groove 22 is formed on the key 20, and a limiting post 41 is formed on the valve stem 40. The groove wall of the limiting groove 22 can form a limiting engagement with the outer wall of the limiting post 41, so that the key 20 can drive the valve stem 40 to rotate, controlling the valve to open or close. The limiting post 41 is flat in shape, and the groove wall of the limiting groove 22 is clamped in the limiting post 41, thereby forming a limiting engagement between the key 20 and the valve stem 40.

[0044] In one embodiment, a first protrusion 32 is formed on the unlocking member 30, and a second protrusion 23 is formed on the bottom of the unlocking groove 21. The first protrusion 32 and the second protrusion 23 are correspondingly arranged so that the unlocking member 30 can abut against the bottom of the unlocking groove 21. This arrangement makes it difficult for others to imitate the unlocking member 30, improving the security and reliability of the magnetic valve lock structure 100. The first protrusion 32 and the second protrusion 23 cooperate with each other, increasing the variation of the unlocking member 30 and the key 20. If the protrusion shapes of the first protrusion 32 and the second protrusion 23 do not match, the unlocking member 30 cannot abut against the bottom of the unlocking groove 21, and the unlocking member 30 will be stuck by the lock body 10, preventing the key 20 from being pushed smoothly.

[0045] Specifically, the first raised block 32 and the second raised block 23 are Chinese characters or radicals of Chinese characters. Of course, the first raised block 32 and the second raised block 23 can also be designed as other patterns, shapes or characters.

[0046] In one embodiment, the magnetic valve lock structure 100 further includes a valve cap (not shown), which is disposed on the valve cover 50. A second unlocking magnet is provided on the key 20, and a third unlocking magnet is disposed between the valve cover 50 and the valve cap. When the key 20 and the valve stem 40 form a limiting engagement, the third unlocking magnet can generate a repulsive force under the action of the second unlocking magnet, thereby unlocking the valve cover 50 from the valve cap. Thus, through the cooperation of the second and third unlocking magnets, double unlocking is achieved, enhancing security. Before unlocking, the valve cap and valve cover 50 are physically interlocked by the third unlocking magnet. After unlocking, the valve cap can rotate freely, thereby driving the valve stem 40 to rotate, thus opening and closing the valve. The valve cap, valve cover 50, and second unlocking magnet are prior art and will not be described in detail here.

[0047] In one embodiment, a sealing opening 14 is provided on the side of the lock body 10, and the sealing opening 14 communicates with the sliding cavity 11. During installation, the key 20 enters the sliding cavity 11 through the sealing opening, making the installation of the key 20 more convenient.

[0048] Furthermore, a cap is provided at the location of the seal 14 to seal the seal 14.

[0049] In one embodiment, the lock body 10 is further provided with a rotating connection hole 15. One end of the valve stem 40 is rotatably connected to the lock body 10 through a connector passing through the rotating connection hole 15, thereby realizing the rotatable connection between the valve stem 40 and the lock body 10. In this way, when the magnetic valve lock structure 100 is in the locked state, the lock body 10 rotates freely around the valve stem 40. The connector can be a bolt, screw, or pin, etc.

[0050] like Figure 5 As shown, in one embodiment, a sealing element is provided between the valve stem 40 and the valve cover 50 to form a seal between them. A sealing groove 42 is provided on the valve stem 40, and the sealing element is installed within the sealing groove 42. The sealing element is provided to prevent media from seeping in and damaging the magnetic structure.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the patent protection scope of this utility model should be determined by the appended claims.
