Shielding cabinet applying labor-saving technology

Abstract

The application discloses a shielding cabinet applying labor-saving technology, which comprises a cabinet body and a cabinet door. The cabinet body is provided with a containing cavity and a cabinet opening. The cabinet door is hinged to the cabinet body and has a to-be-closed position and a completely closed position based on its rotation. The cabinet body is provided with an elastic conductive structure around the cabinet opening or the cabinet door is provided with the elastic conductive structure corresponding to the periphery of the cabinet opening. The cabinet door is provided with a door lock mechanism which is designed ingeniously. When the cabinet door is rotated to the to-be-closed position, only the rotation of an operating part can continuously complete the rotation of the cabinet door to the completely closed position and the locking operation. The design is not only simple and convenient, but also stable and controllable. On the other hand, the reaction force of the elastic conductive structure on the cabinet door is transmitted to the operating part by the door lock mechanism and is converted into the force impeding the rotation of the operating part. Compared with directly applying a front pushing force to overcome the reaction force of the elastic conductive structure, the rotation of the operating part to overcome the rotation resistance is more labor-saving, so that the force required by a user to close the cabinet door is effectively reduced.

Description

Technical Field

[0001] This invention relates to the field of electromagnetic shielding technology, and in particular to a shielding cabinet that applies labor-saving technology. Background Technology

[0002] Mobile phone shielding cabinets are professional devices that use physical shielding technology to block wireless signals. Their core principle is to attenuate and absorb electromagnetic waves through a shielding space made of metal materials, so that mobile phones inside the cabinet cannot establish communication with base stations.

[0003] To reduce the negative impact of the gap between the cabinet door and the cabinet body on the shielded cabinet, an elastic conductive structure, such as a copper sheet or conductive sponge strip, is usually installed around the edge of the cabinet opening or the corresponding position of the cabinet door. When the cabinet door is fully closed, the elastic conductive structure is squeezed by the cabinet door and the cabinet body, and forms a conductive connection with the two, thereby effectively suppressing signals from entering or leaving the shielded cabinet through this point.

[0004] Because the force required to close an elastic conductive structure increases with the extent of compression, the user must gradually increase the force applied to the door as it rotates, starting from when the elastic conductive structure begins to be compressed by the door and cabinet body. To address this, most existing shielded cabinets install magnets on the cabinet body and / or door, using magnetic attraction to counteract the reaction force of the elastic conductive structure and reduce the force required to close the door. However, this structure presents two unavoidable problems: First, opening the door requires additional force to overcome the magnetic attraction, leading to inconvenience and a negative user experience. Second, closing the door is difficult to control; under the influence of magnetic attraction, the door may suddenly accelerate and impact the cabinet body as it approaches the closed position, producing a loud noise and vibration, resulting in a poor user experience.

[0005] Therefore, the aforementioned existing technologies urgently need improvement. Summary of the Invention

[0006] The purpose of this invention is to provide a shielding cabinet that uses labor-saving technology, which makes opening and closing the cabinet door more convenient and labor-saving while ensuring the shielding effect, thereby improving the user experience.

[0007] To achieve the above objectives, one of the technical solutions adopted by the present invention is as follows:

[0008] A shielding cabinet employing labor-saving technology includes a cabinet body and a cabinet door. The cabinet body has a receiving cavity and a cabinet opening communicating with it. The cabinet door is hinged to the cabinet body and has a pre-closed position and a fully closed position based on its own rotation. An elastic conductive structure is provided on the cabinet body around the cabinet opening or on the cabinet door at a position corresponding to the periphery of the cabinet opening.

[0009] The cabinet door is equipped with a door locking mechanism, which includes a locking element and an operating element. The locking element is rotatable about a first axis parallel to the plane of the cabinet door and includes a first swing arm with the first axis as its swing center. The operating element is located on the front of the cabinet door and is rotatable about a second axis perpendicular to the plane of the cabinet door. The locking element and the operating element are drively connected, and the locking element rotates as the operating element rotates. The door locking mechanism thus has an unlocked state and a locked state.

[0010] The cabinet includes a mating part corresponding to the first swing arm, and the door lock mechanism is mated with the mating part in the following manner:

[0011] When the cabinet door rotates to the position to be closed, the free end of the first swing arm of the door lock mechanism in the unlocked state is further back than the mating part; during the process of the door lock mechanism switching from the unlocked state to the locked state, the first swing arm swings from back to front and presses against the mating part, thereby the mating part applies a force to the cabinet door to help it rotate to the fully closed position; until the door lock mechanism switches to the locked state, the cabinet door reaches the fully closed position, at which time the elastic conductive structure is compressed by the cabinet door and the cabinet body, and the receiving cavity forms a shielding space.

[0012] Based on the above technical solution, when a user needs to close and lock the cabinet door, they only need to rotate the cabinet door to the desired closed position, and then rotate the operating component in the forward direction to switch the door lock mechanism from the unlocked state to the locked state. With the assistance of the first swing arm pressing against the mating part, the cabinet door can then be rotated to the fully closed position, simultaneously pressing the elastic conductive structure. Conversely, when a user needs to release and open the cabinet door, they only need to rotate the operating component in the reverse direction to switch the door lock mechanism from the locked state to the unlocked state, and then rotate the cabinet door.

[0013] The door lock mechanism is ingeniously designed, significantly enhancing the user experience.

[0014] On the one hand, once the cabinet door is rotated to the position to be closed, simply rotating the operating component is sufficient to continuously complete the rotation and locking operations of the cabinet door to the fully closed position. This is not only simple and convenient, but also stable and controllable, and will not cause noise or vibration caused by the cabinet door hitting the cabinet body.

[0015] On the other hand, the door lock mechanism transmits the reaction force of the elastic conductive structure acting on the cabinet door to the operating member through the first swing arm, and converts it into a force that resists the rotation of the operating member. Compared with directly applying a frontal thrust to overcome the reaction force of the elastic conductive structure, overcoming the rotational resistance by rotating the operating member is more effortless, thereby effectively reducing the force required for the user to close the cabinet door.

[0016] In addition, the door lock mechanism is also easy to operate when releasing and opening the cabinet door, and does not have the drawbacks of magnetic technology.

[0017] In the above technical solution, the door lock mechanism further includes a transmission component that drivesly connects the lock and the operating component.

[0018] The transmission assembly includes a rotating component that can rotate about a third axis perpendicular to the plane of the cabinet door. The rotating component is drively connected to the operating component and can rotate as the operating component rotates.

[0019] The rotating component has a guide surface that extends helically around the third axis, and the projected area of ​​the guide surface on a plane perpendicular to the third axis is greater than zero. The locking component further includes a second swing arm with the first axis as its swing center, and the second swing arm is disposed opposite to the guide surface.

[0020] During the process of the door lock mechanism switching from the unlocked state to the locked state, the rotating member rotates in the forward direction, the guide surface pushes the second swing arm to swing in the forward direction, so that the lock member rotates in the forward direction, thereby driving the first swing arm to swing from back to front and press against the mating part.

[0021] Based on the above technical solution, since the guide surface is inclined, the second swing arm can slide smoothly on the guide surface, so the user can easily rotate the operating component to achieve the purpose of closing the cabinet door with less effort.

[0022] In the above technical solution, the transmission component further includes an elastic element, which applies a force between the lock and the cabinet door, such that the second swing arm abuts against the guide surface when the door lock mechanism switches between the unlocked state and the locked state.

[0023] During the process of the door lock mechanism switching from the locked state to the unlocked state, the rotating member rotates in the opposite direction, and the elastic member drives the second swing arm to swing in the opposite direction, causing the lock to rotate in the opposite direction, thereby driving the first swing arm to swing from front to back and separate from the mating part.

[0024] In the above technical solution, the rotating component includes a cylindrical body and a push block disposed on its outer peripheral surface, wherein the center line of the cylindrical body is the third axis. On a plane perpendicular to the third axis, the projection of the push block only partially surrounds the projection of the cylindrical body.

[0025] The push block includes a stop end along the third axis, and the guide surface extends spirally from the stop end around the third axis on the push block. When the door lock mechanism is in the locked state, the second swing arm abuts against the stop end.

[0026] The advantage of this design is that the cut-off end can ensure that the second swing arm remains stable when the door lock mechanism is in the locked state, and avoid the second swing arm from sliding on the guide surface due to the reaction force of the elastic conductive structure and / or other external forces, which would cause the locked state to fail.

[0027] In the above technical solution, the rotating component further includes a thrust surface disposed on the push block and perpendicular to the third axis. Along the positive direction, the thrust surface connects to the end of the guide surface, and is used for the second swing arm to abut against when the door lock mechanism is in the unlocked state.

[0028] On the one hand, the thrust surface can limit the excessive reverse rotation of the lock, thus providing a good limiting effect. On the other hand, the smooth connection between the thrust surface and the guide surface allows the second swing arm to move smoothly onto the guide surface when the door lock mechanism switches from the unlocked state to the locked state, thereby ensuring smooth rotation of the operating component and effectively improving the user's operating experience.

[0029] In the above technical solution, the part of the second swing arm that contacts the guide surface is arc-shaped to improve its sliding performance on the guide surface.

[0030] In the above technical solution, the projections of the first swing arm and the second swing arm onto a plane perpendicular to the first axis point in opposite directions. That is, the first swing arm and the second swing arm are 180° apart.

[0031] The guide surface faces the rear of the cabinet door, and the second swing arm is located behind the guide surface. Along the positive direction, the guide surface extends spirally from back to front.

[0032] When the lock rotates in the forward direction, the second swing arm swings from front to back, and the first swing arm swings from back to front. When the lock rotates in the reverse direction, the second swing arm swings from back to front, and the first swing arm swings from front to back.

[0033] In other technical solutions, the projections of the first swing arm and the second swing arm on a plane perpendicular to the first axis overlap.

[0034] The guide surface faces the front of the cabinet door, and the second swing arm is located on the front of the guide surface. Along the positive direction, the guide surface extends spirally from front to back.

[0035] When the lock rotates in the forward direction, both the first and second swing arms swing from back to front. When the lock rotates in the reverse direction, both the first and second swing arms swing from front to back.

[0036] In the above technical solution, the first axis is parallel to the hinge axis of the cabinet door and is located at the end of the cabinet door away from the hinge axis. That is, the lock is located at the end of the cabinet door away from the hinge axis, which can improve the stability when locking.

[0037] The third axis is located on the side of the first axis closest to the hinge axis and is adjacent to the first axis. That is, the rotating member and the locking member are arranged compactly, which saves installation space.

[0038] In the above technical solution, the locking component further includes a pivot, the center line of which is the first axis. Both the first swing arm and the second swing arm extend and protrude from the pivot.

[0039] The rotating shaft has a certain length. There are at least two first swing arms, with each of the first swing arms positioned near one end of the rotating shaft. The second swing arm is positioned near the middle of the rotating shaft.

[0040] On the one hand, by setting multiple first swing arms, the reliability of the locking component can be effectively improved. On the other hand, the even distribution of the first and second swing arms on the rotating shaft can make the locking component more evenly stressed, thereby reducing the possibility of deformation and damage.

[0041] In the above technical solution, the rotating component includes a limiting block protruding radially therefrom, and the cabinet door includes a first stop and a second stop arranged circumferentially around the rotating component. When the rotating component rotates, the first stop and the second stop restrict the limiting block to swing between themselves.

[0042] When the limiting block abuts against the first stop, the door lock mechanism enters the unlocked state; when the limiting block abuts against the second stop, the door lock mechanism enters the unlocked state.

[0043] In the above technical solution, the limiting block is disposed on the outer peripheral surface of the columnar body.

[0044] In the above technical solution, the third axis coincides with the second axis, and the rotating component is located behind the operating component. The operating component includes a connecting section, which is coaxially connected to the rotating component.

[0045] In the above technical solution, the operating component further includes a polygonal pin connected to the rear end of the connecting segment. The columnar body has a shaft hole extending along the third axis and adapted to the shape of the pin. The pin is inserted into the shaft hole to coaxially connect the connecting segment and the rotating component.

[0046] In the above technical solution, the cabinet door includes a mounting plate, and the lock, the rotating component, and the operating component are all located on the front side of the mounting plate. Specifically, the rotating shaft of the lock is mounted to the mounting plate via a U-shaped bracket, and the operating component, together with the rotating component, is mounted to the mounting plate via a support.

[0047] The mounting plate is provided with a cutout to avoid the locking member and the rotating member. The cutout includes a fan-shaped area that provides swing space for the limiting block. One edge of the fan-shaped area is the first stop portion, and the other edge is the second stop portion.

[0048] In the above technical solution, due to the restriction of the first stop and the second stop, the rotational stroke of the rotating member corresponding to the door lock mechanism switching between the unlocked state and the locked state is 0~90°.

[0049] In the above technical solution, the operating component is an L-shaped door handle, which also includes a lever connected to the connecting section. When the door lock mechanism is in the unlocked state, the lever is vertically downward; when the door lock mechanism is in the locked state, the lever is horizontal.

[0050] Therefore, the operating component has a leverage effect, making it easier to operate. Moreover, when closing and locking the cabinet door, pulling the door handle upwards is more conducive to exerting force and also conforms to people's operating habits.

[0051] In the above technical solution, the rotational stroke of the lock component corresponding to the door lock mechanism switching between the unlocked state and the locked state is 0~α, 20°≤α≤60°.

[0052] With a fixed rotational stroke of the rotating component, the value of α is related to the slope of the guide surface. The greater the slope of the guide surface, the greater the value of α; the greater the slope of the guide surface, the smaller the value of α.

[0053] If α < 20°, the rotational stroke of the lock is insufficient to cause a significant positional change in the first swing arm, making it difficult to simultaneously satisfy the following conditions: when the door lock mechanism is in the unlocked state, the first swing arm will not interfere with the mating part; when the door lock mechanism is in the locked state, the first swing arm can stably press against the mating part. If α > 60°, there is functional redundancy, and the slope of the guide surface will be too large, resulting in an excessively large rotating component that is difficult to install. Therefore, 20° ≤ α ≤ 60° is a more suitable range.

[0054] In the above technical solution, when the door lock mechanism is in the locked state, the first swing arm is parallel to the plane of the cabinet door. That is, the first swing arm acts like a bolt, blocking the rear side of the mating part, which can effectively improve the stability and reliability of the lock when it is locked.

[0055] In the above technical solution, the elastic element is a tension spring, which is located on the rear side of the mounting plate. One end of the tension spring is connected to the mounting plate by a pin, and the other end is connected to the first swing arm.

[0056] In the above technical solution, the cabinet includes a hook corresponding to the first swing arm, and the straight part formed by bending the end of the hook is parallel to the plane where the cabinet opening is located, which is the mating part.

[0057] The lock and the transmission assembly are located inside the cabinet door, and the back of the cabinet door has an opening for the hook to enter and exit, corresponding to the position of the hook.

[0058] In the above technical solution, the folding hook is located on the front of the cabinet.

[0059] On the one hand, most of the components of the door lock mechanism are located inside the cabinet door, thereby improving the aesthetics of the shielding cabinet and reducing the probability of damage to the components. On the other hand, the mating part protrudes from the cabinet body in the form of a hook, which facilitates the first straight arm to press against it.

[0060] Compared with the prior art, the shielding cabinet provided by the present invention has at least the following beneficial effects:

[0061] Firstly, when closing the cabinet door, after rotating the cabinet door to the closed position, simply rotating the operating component is sufficient to continuously complete the rotation and locking operation of the cabinet door to the fully closed position. This is not only simple and convenient, but also stable and controllable, and will not cause noise or vibration caused by the cabinet door hitting the cabinet body.

[0062] Secondly, the door lock mechanism transmits the reaction force exerted on the cabinet door by the elastic conductive structure to the operating component through the first swing arm, and converts it into a force that resists the rotation of the operating component. Compared with directly applying a frontal thrust to overcome the reaction force of the elastic conductive structure, overcoming the rotational resistance by rotating the operating component is more effortless, thus effectively reducing the force required for the user to close the cabinet door.

[0063] Third, the door lock mechanism is equally convenient to operate when releasing and opening the cabinet door, and there are no drawbacks associated with magnetic technology. Attached Figure Description

Detailed Implementation

[0086] The present invention will now be described in more detail with reference to specific embodiments. Those skilled in the art should understand that these descriptions merely illustrate some specific embodiments of the invention and do not limit the scope of the invention in any way.

[0087] To facilitate the description of the positional relationships between the components in the accompanying drawings, this document will use spatial relative orientation terms such as "front," "rear," "front end," and "rear end." It should be understood that spatial relative orientation not only covers the directions shown in the drawings but also includes various possible orientations in actual use and operation of the embodiments. For example, when the device in the drawings is inverted, a component originally described as being "in front" of other components will be reoriented to be "rear" of those components. Furthermore, the structures shown in the accompanying drawings are for illustrative purposes only and do not represent the actual structure of the invention, nor do they limit the scope of protection of the invention.

[0088] Furthermore, terms such as "first" and "second" in this document are not intended to emphasize the quantity, order, or importance of the components referred to. Unless otherwise stated, terms such as "installed," "connected," and "linked" in this document should be interpreted broadly. For example, they can refer to fixed connections, integral connections, or detachable connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art should understand the specific meaning of the above terms in this document according to the specific circumstances. In addition, terms such as "greater than," "less than," and "exceeding" in this document are understood to exclude the stated number; terms such as "above," "below," and "within" are understood to include the stated number; and "multiple" means two or more.

[0089] See Figures 1 to 3 This embodiment provides a shielded cabinet for storing electronic products with communication functions, such as mobile phones, tablets, and laptops. The shielded cabinet includes a cabinet body 100 and a cabinet door 200. The cabinet body 100 has a receiving cavity 101 and a cabinet opening connected thereto. The cabinet door 200 is hinged to the cabinet body 100 and has a partially closed position and a fully closed position based on its own rotation. An elastic conductive structure 300 is provided on the cabinet door 200 at a position corresponding to the periphery of the cabinet opening.

[0090] The fully closed position refers to the position of the cabinet door 200 when the plane containing the cabinet door 200 is parallel or nearly parallel to the plane containing the cabinet opening. At this point, the cabinet door 200 has completely closed the cabinet opening.

[0091] The "to be closed" position refers to the position of the cabinet door 200 when the plane of the cabinet door 200 is nearly parallel to the plane of the cabinet opening, but there is still an angle of 0.5 to 6 degrees. At this time, the cabinet door 200 is close to closing the cabinet opening, and the part of the elastic conductive structure 300 near the hinge axis of the cabinet door 200, or even the entire elastic conductive structure 300, has begun to be squeezed by the cabinet door 200 and the cabinet body 100. However, in the area far from the hinge axis of the cabinet door 200, there is still a slight gap between the cabinet door 200 and the cabinet body 100, or the elastic conductive structure 300 has only just been squeezed.

[0092] like Figures 1 to 13 As shown, the cabinet door 200 is equipped with a door lock mechanism, which includes a lock element 1, an operating element 2, and a transmission assembly. The lock element 1 is rotatable about a first axis 400 parallel to the plane of the cabinet door 200, and includes a first swing arm 11 with the first axis 400 as its swing center. The operating element 2 is located on the front of the cabinet door 200 and is rotatable about a second axis 500 perpendicular to the plane of the cabinet door 200. The transmission assembly connects the lock element 1 and the operating element 2, so that the lock element 1 can rotate as the operating element 2 rotates. Based on the positional change caused by the operating element 2 driving the lock element 1, the door lock mechanism has an unlocked state and a locked state.

[0093] The cabinet 100 includes a hook 8 corresponding to the first swing arm 11, which is located on the front of the cabinet 100. The straight portion formed by bending the end of the hook 8, parallel to the plane of the cabinet opening, is the mating part 81. The door lock mechanism and the mating part 81 are mated as follows:

[0094] When the cabinet door 200 rotates to the position to be closed, the free end of the first swing arm 11 of the door lock mechanism, which is in the unlocked state, is further back than the mating part 81. During the process of the door lock mechanism switching from the unlocked state to the locked state, the first swing arm 11 swings from back to front and presses against the mating part 81, thereby applying a force to the cabinet door 200 to help it rotate to the fully closed position. Until the door lock mechanism switches to the locked state, the cabinet door 200 reaches the fully closed position. At this time, the elastic conductive structure 300 is compressed by the cabinet door 200 and the cabinet body 100, and the receiving cavity 101 forms a shielded space.

[0095] It is understandable that when the door lock mechanism is in the unlocked state, the first swing arm 11 does not interfere with the mating part 81 during the rotation of the cabinet door 200, so as to ensure that the cabinet door 200 rotates smoothly.

[0096] Based on the above technical solution, when a user needs to close and lock the cabinet door 200, they only need to rotate the cabinet door 200 to the closed position, and then rotate the operating member 2 in the forward direction to switch the door lock mechanism from the unlocked state to the locked state. With the assistance of the first swing arm 11 pressing against the mating part 81, the cabinet door 200 can be rotated to the fully closed position, while simultaneously pressing the elastic conductive structure 300. Conversely, when a user needs to release and open the cabinet door 200, they only need to rotate the operating member 2 in the reverse direction to switch the door lock mechanism from the locked state to the unlocked state, and then rotate the cabinet door 200.

[0097] This door lock mechanism is ingeniously designed, significantly enhancing the user experience. Firstly, once the cabinet door 200 is rotated to the closed position, simply rotating the operating component 2 is sufficient to continuously rotate and lock the door 200 to the fully closed position. This is not only simple and convenient but also stable and controllable, preventing noise and vibration caused by the cabinet door 200 impacting the cabinet body 100. Secondly, the door lock mechanism transmits the reaction force exerted on the cabinet door 200 by the elastic conductive structure 300 to the operating component 2 via the first swing arm 11, converting it into a force that resists the rotation of the operating component 2. Compared to directly applying a frontal thrust to overcome the reaction force of the elastic conductive structure 300, overcoming the rotational resistance by rotating the operating component 2 requires less effort, effectively reducing the force required for the user to close the cabinet door 200. Furthermore, this door lock mechanism is equally convenient to operate when releasing and opening the cabinet door 200, eliminating the drawbacks of magnetic technology.

[0098] like Figures 3 to 6 As shown, the lock 1 and transmission assembly are located inside the cabinet door 200. An opening 202 for the hook 8 to enter and exit is provided on the back of the cabinet door 200 corresponding to the position of the hook 8. On one hand, the fact that most of the components of the door lock mechanism are located inside the cabinet door 200 improves the aesthetics of the shielding cabinet and reduces the probability of damage to each component. On the other hand, the mating part 81 protrudes from the cabinet body 100 in the form of a hook 8, which facilitates the first straight arm's contact with it.

[0099] like Figures 6 to 18 As shown, the transmission assembly includes a rotating component 3, which can rotate about a third axis 600 perpendicular to the plane where the cabinet door 200 is located. The rotating component 3 is connected to the operating component 2 and can rotate as the operating component 2 rotates.

[0100] The rotating component 3 includes a cylindrical body 31 and a pusher block 32 disposed on its outer peripheral surface. The center line of the cylindrical body 31 is the third axis 600. On a plane perpendicular to the third axis 600, the projection of the pusher block 32 only partially surrounds the projection of the cylindrical body 31.

[0101] The push block 32 has a guide surface 321, the projected area of ​​which on a plane perpendicular to the third axis 600 is greater than zero. The guide surface 321 faces the rear side of the cabinet door 200 and extends spirally from the rear end of the push block 32 around the third axis 600 in a positive direction.

[0102] The locking component 1 also includes a second swing arm 12 with the first axis 400 as the swing center, and the second swing arm 12 is disposed opposite to the guide surface 321.

[0103] The transmission assembly also includes an elastic element that applies a force between the lock 1 and the cabinet door 200, causing the second swing arm 12 to abut against the guide surface 321 when the door lock mechanism switches between the unlocked and locked states.

[0104] During the process of switching the door lock mechanism from the unlocked state to the locked state, the rotating part 3 rotates in the forward direction, and the guide surface 321 pushes the second swing arm 12 to swing in the forward direction, so that the lock part 1 rotates in the forward direction, thereby driving the first swing arm 11 to swing from back to front and press against the mating part 81.

[0105] During the process of switching the door lock mechanism from the locked state to the unlocked state, the rotating part 3 rotates in the opposite direction, and the elastic part drives the second swing arm 12 to swing in the opposite direction, causing the lock part 1 to rotate in the opposite direction, which in turn drives the first swing arm 11 to swing from front to back and separate from the mating part 81.

[0106] Based on the above technical solution, since the guide surface 321 is an inclined surface, the second swing arm 12 can slide smoothly on the guide surface 321, so the user can easily rotate the operating part 2 to achieve the purpose of closing the cabinet door 200 with effort.

[0107] In this embodiment, the part of the second swing arm 12 that contacts the guide surface 321 is arc-shaped to improve its sliding performance on the guide surface 321.

[0108] like Figures 11 to 15 As shown, the rear end of the push block 32 is a stop end. When the door lock mechanism is in the locked state, the second swing arm 12 abuts against this stop end. The advantage of this design is that the stop end can ensure that the second swing arm 12 remains stable when the door lock mechanism is in the locked state, and prevent the second swing arm 12 from sliding on the guide surface 321 due to the reaction force of the elastic conductive structure 300 and / or other external forces, which would cause the locking state to fail.

[0109] The push block 32 also has a thrust surface 322 perpendicular to the third axis 600. In the positive direction, the thrust surface 322 connects to the end of the guide surface 321. When the door lock mechanism is in the unlocked state, the second swing arm 12 abuts against the thrust surface 322.

[0110] On the one hand, the thrust surface 322 can limit the excessive reverse rotation of the lock element 1 under the force of the elastic element, thus achieving a good limiting effect. On the other hand, the smooth connection between the thrust surface 322 and the guide surface 321 allows the second swing arm 12 to move smoothly onto the guide surface 321 when the door lock mechanism switches from the unlocked state to the locked state, thereby ensuring that the rotation of the operating element 2 is smooth and effectively improving the user's operating experience.

[0111] like Figures 9 to 17 As shown, the projections of the first swing arm 11 and the second swing arm 12 onto a plane perpendicular to the first axis 400 point in opposite directions. That is, the first swing arm 11 and the second swing arm 12 are 180° apart.

[0112] When the locking element 1 rotates in the forward direction, the second swing arm 12 swings from front to back, and the first swing arm 11 swings from back to front. When the locking element 1 rotates in the reverse direction, the second swing arm 12 swings from back to front, and the first swing arm 11 swings from front to back.

[0113] like Figures 9 to 17 As shown, the lock 1 also includes a pivot 13 of a certain length, the center line of which is the first axis 400. Both the first swing arm 11 and the second swing arm 12 extend and protrude from the pivot 13. There are two first swing arms 11, each positioned near one end of the pivot 13. The second swing arm 12 is positioned near the middle of the pivot 13.

[0114] On the one hand, by setting multiple first swing arms 11, the reliability of the lock 1 can be effectively improved. On the other hand, the first swing arms 11 and the second swing arms 12 are evenly distributed on the rotating shaft 13, which can make the lock 1 more evenly stressed, thereby reducing the possibility of deformation and damage.

[0115] like Figures 1 to 3 As shown, the first axis 400 is parallel to the hinge axis of the cabinet door 200 and is located at the end of the cabinet door 200 away from its hinge axis. That is, the locking element 1 is located at the end of the cabinet door 200 away from the hinge axis, which can improve the stability when locking. The third axis 600 is located on the side of the first axis 400 close to the hinge axis and is adjacent to the first axis 400. That is, the rotating element 3 and the locking element 1 are arranged compactly, which can save installation space.

[0116] like Figure 9 , Figure 10 , Figure 14 , Figure 15 , Figure 18 As shown, the third axis 600 coincides with the second axis 500, and the rotating component 3 is located behind the operating component 2. The operating component 2 includes a connecting section 21, which is coaxially connected to the rotating component 3.

[0117] The operating component 2 also includes a polygonal pin 22 connected to the rear end of the connecting section 21. The cylindrical body 31 of the rotating component 3 is provided with a shaft hole 311 extending along the third axis 600 and adapted to the shape of the pin 22. The pin 22 is inserted into the shaft hole 311 to coaxially connect the connecting section 21 and the rotating component 3.

[0118] like Figures 19 to 21 As shown, the cabinet door 200 includes a mounting plate 201, and a lock 1, a rotating component 3, and an operating component 2 are all located on the front side of the mounting plate 201. The rotating shaft 13 of the lock 1 is mounted on the mounting plate 201 via a U-shaped bracket 4, and the operating component 2, along with the rotating component 3, is mounted on the mounting plate 201 via a bracket 5. The mounting plate 201 has a cutout 2011 to allow the lock 1 and the rotating component 3 to pass through.

[0119] like Figures 16 to 21 As shown, the rotating member 3 also includes a limiting block 33 protruding radially therefrom, which is disposed on the outer peripheral surface of the columnar body 31. The cutout 2011 includes a fan-shaped region 2012 that provides swing space for the limiting block 33. One edge of the fan-shaped region 2012 is a first stop 2013, and the other edge is a second stop 2014. That is, the first stop 2013 and the second stop 2014 are arranged circumferentially around the rotating member 3. When the rotating member 3 rotates, the first stop 2013 and the second stop 2014 restrict the limiting block 33 to swing between them. When the limiting block 33 abuts against the first stop 2013, the door lock mechanism enters the unlocked state; when the limiting block 33 abuts against the second stop 2014, the door lock mechanism enters the unlocked state.

[0120] like Figure 9 , Figure 10 , Figure 14 as well as Figure 15 As shown, due to the restriction of the first stop 2013 and the second stop 2014, the rotational stroke of the rotating member 3 corresponding to the door lock mechanism switching between the unlocked and locked states is 0~90°. Correspondingly, the rotational stroke of the operating member 2 is also 0~90°.

[0121] like Figures 9 to 18 As shown, the operating component 2 is an L-shaped door handle, which also includes a handle 23 connected to the connecting section 21. When the door lock mechanism is in the unlocked state, the handle 23 is vertically downward; when the door lock mechanism is in the locked state, the handle 23 is horizontal.

[0122] Based on this, the operating component 2 has a lever effect, making it easier to operate. Moreover, when closing and locking the cabinet door 200, pulling the door handle upwards is more conducive to exerting force and also conforms to people's operating habits.

[0123] by Figure 1 and Figure 2For example, if the vertically downward operating member 2 of the lever 23 is rotated 90° counterclockwise so that the lever 23 is horizontal, the door lock mechanism will change from the unlocked state to the locked state; if the horizontally horizontal operating member 2 of the lever 23 is rotated 90° clockwise so that the lever 23 is vertically downward, the door lock mechanism will change from the locked state to the unlocked state.

[0124] In this embodiment, the rotational stroke of the lock component 1 corresponding to the door lock mechanism switching between the unlocked and locked states is 0~40°. This stroke range can simultaneously satisfy the following: when the door lock mechanism is in the unlocked state, the first swing arm 11 will not interfere with the mating part 81; when the door lock mechanism is in the locked state, the first swing arm 11 can stably press against the mating part 81. Furthermore, it will not result in an excessively large slope of the guide surface 321, ensuring that the rotating component 3 has an appropriate size and is easy to install.

[0125] In this embodiment, when the door lock mechanism is in the locked state, the first swing arm 11 is parallel to the plane of the cabinet door 200. That is, the first swing arm 11 acts like a bolt, blocking the rear side of the mating part 81, which can effectively improve the stability and reliability of the lock 1 when it is locked.

[0126] like Figure 21 As shown, the elastic element is a tension spring 6, which is located on the rear side of the mounting plate 201. One end of the tension spring 6 is connected to the mounting plate 201 via a pin 7, and the other end is connected to the first swing arm 11.

[0127] It should be noted that in this embodiment, regardless of the position of the cabinet door 200, the front side of the cabinet door 200 refers to the side facing it, and the rear side of the cabinet door 200 refers to the side facing it.

[0128] The above description is for illustrative purposes only and is not intended to limit the invention. It should be noted that those skilled in the art can make various improvements, modifications, and variations to the invention, but such improvements, modifications, and variations should all be considered to fall within the protection scope of the invention without departing from its spirit.
