Description

Technical Field

[0001] This utility model belongs to the field of cabinet lock technology, and more specifically, it relates to an anti-vibration door lock and cabinet. Background Technology

[0002] In existing technologies, power cabinet structures are relatively simple, especially for cabinets that use single-point locks for door locking. When the cabinet is transported or in a vibrating working environment, the lock plate is easily unlocked due to vibration or shaking. After the lock plate unlocks the cabinet, the door, no longer restrained, springs open, affecting the normal operation of internal electrical components. Furthermore, during transport, the door may collide with surrounding parts, causing deformation or damage. Using multi-point locks for door locking would increase production costs and occupy significant internal space, affecting the rational layout of internal electrical components. Utility Model Content

[0003] The purpose of this utility model is to provide an anti-vibration door lock and cabinet, which aims to solve the problem that when the cabinet door is locked to the cabinet body using a single-point lock in the existing technology, the lock plate is prone to move in unstable environments such as transportation, which leads to the cabinet door being accidentally unlocked, resulting in damage to the cabinet door and exposure of the internal electrical components of the cabinet.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] Firstly, an earthquake-resistant door lock is provided, comprising:

[0006] Drive components for connection to the cabinet door;

[0007] A latch assembly includes a plurality of latches spaced apart sequentially along an inward and outward direction, the plurality of latches being coaxially connected to a drive assembly; and

[0008] The fixing component includes multiple fixing members distributed sequentially in the inward and outward directions. Each of the fixing members is used to connect to the cabinet. The locking tongue is provided in a one-to-one correspondence with the fixing member. The locking tongue has a locked state when it is engaged with the corresponding fixing member and an unlocked state when it is disengaged from the corresponding fixing member. The driving component is used to drive the multiple locking tongues to rotate synchronously so as to switch the locking tongue between the locked state and the unlocked state.

[0009] In conjunction with the first aspect, in one possible implementation, the locking tongue includes:

[0010] A connecting part, connected to the drive assembly; and

[0011] A locking part is connected to the connecting part for locking with the fixing member. The locking part includes a locking piece and a guide flange connected to the locking piece. The guide flange is bent inward. In the locked state, the guide flange is connected to the upper and lower sides of the locking piece, respectively.

[0012] In conjunction with the first aspect, in one possible implementation, the fastener includes:

[0013] Fixing part, used for connection with the cabinet; and

[0014] The limiting part includes a limiting piece connected to the fixing part and an avoidance flange connected to the fixing part. The limiting piece is connected to the fixing part at an angle, and the avoidance flange is bent outward. When the lock tongue switches from the unlocked state to the locked state, the avoidance flange is used to avoid the lock tongue.

[0015] In conjunction with the first aspect, in one possible implementation, the fastener further includes a limiting flange connected to the limiting piece, the limiting flange being bent inward and angled with the limiting piece, and the limiting flange and the abutment flange being located on opposite sides of the limiting piece, the limiting flange being used to limit the rotational distance of the locking tongue.

[0016] In conjunction with the first aspect, in one possible implementation, the locking tongue includes:

[0017] A connecting part, connected to the drive assembly; and

[0018] A locking part is connected to the connecting part and is used to lock with the fixing member. The locking part includes a connecting piece and a locking piece distributed at an angle. The connecting piece is connected to the connecting part, and the connecting part and the locking part form a "Z" shaped structure. The fixing member has a fixing hole. The connecting piece is inserted into the fixing hole, and the locking piece passes through the fixing hole and is located on the inner side of the fixing member.

[0019] In conjunction with the first aspect, in one possible implementation, the fastener includes a locking part, a transition part, and an unlocking part arranged sequentially from top to bottom. The width of the unlocking part is greater than that of the locking part. The transition part forms a smooth transition slope between the locking part and the unlocking part. In the locked state, the latch abuts against the locking part in the inward and outward directions. In the unlocked state, the latch rotates to the side of the unlocking part.

[0020] In conjunction with the first aspect, in one possible implementation, the fixing member further includes a limiting protrusion disposed on the locking portion, wherein in the locked state, the limiting protrusion abuts against the locking tongue in the vertical direction.

[0021] In conjunction with the first aspect, in one possible implementation, the latch assembly further includes an elastic element connected to the latch, the elastic element being configured with a preload force to keep the latch in a locked state.

[0022] In conjunction with the first aspect, in one possible implementation, the driving component includes:

[0023] A connecting shaft is connected to one of the locking tongues;

[0024] A driver, connected to the connecting shaft, for driving the connecting shaft to rotate about its own axis; and

[0025] The controller is communicatively connected to the driver and connected to the operating terminal.

[0026] The beneficial effects of this anti-vibration door lock are as follows: Compared with the prior art, this anti-vibration door lock utilizes the locking of the latch and corresponding fixing parts to lock the cabinet door to the cabinet body. Because multiple latches are set in both the inner and outer directions, and each latch has a corresponding fixing part, when in the locked state, each latch is locked to its corresponding fixing frame. Multiple locking mechanisms ensure the firmness and reliability of the cabinet door and cabinet body locking. When the cabinet body vibrates or shakes, if one or more latches are displaced under force, they will switch to the unlocked state with their corresponding fixing parts, while the other latches remain locked, preventing the cabinet door from separating from the cabinet body after contact with the constraint. This invention not only improves the reliability of the connection between the cabinet door and cabinet body after locking, but is also simpler than a multi-point lock structure, reducing the space occupied inside the cabinet. Furthermore, the drive assembly controls the rotation of multiple latches to switch between the locked and unlocked states, eliminating the need for intermediate transmission components. This simplifies the structure of the anti-vibration door lock and avoids the intermediate transmission components accidentally engaging the latches due to vibration, causing the latches to switch to the unlocked state.

[0027] Secondly, this utility model embodiment also provides a cabinet, including the aforementioned shock-resistant door lock.

[0028] The beneficial effects of the cabinet provided by this utility model are as follows: Compared with the prior art, the aforementioned anti-vibration door lock utilizes the locking tongue and corresponding fixing parts to lock the cabinet door to the cabinet body. Because multiple locking tongues are set in both the inner and outer directions, and each locking tongue has a corresponding fixing part, when in the locked state, each locking tongue is locked with its corresponding fixing frame. Multiple locking mechanisms ensure the firmness and reliability of the lock between the cabinet door and the cabinet body. When the cabinet body vibrates or shakes, if one or more locking tongues are displaced under force, causing them to switch to the unlocked state with their corresponding fixing parts, while the other locking tongues remain locked, this prevents the cabinet door from separating from the cabinet body after contact with the constraint. This utility model not only improves the reliability of the connection between the cabinet door and the cabinet body after locking, but is also simpler than a multi-point lock structure, reducing the space occupied inside the cabinet. Furthermore, the drive component controls the rotation of multiple locking tongues to switch between the locked and unlocked states, eliminating the need for intermediate transmission components. This simplifies the structure of the anti-vibration door lock and avoids the situation where intermediate transmission components accidentally engage the locking tongue due to vibration, causing the locking tongue to switch to the unlocked state.

[0038] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0039] In the claims, description, and accompanying drawings of this utility model, unless otherwise expressly defined, the terms "first," "second," or "third," etc., are used to distinguish different objects, not to describe a specific order. Unless otherwise stated, other directional terms, such as "vertical," "clockwise," and "counterclockwise," indicate orientation or positional relationships based on the orientation and positional relationships shown in the accompanying drawings, and are only for the convenience of describing the utility model and simplifying the description, not to indicate or imply that the referred device or element must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the specific scope of protection of this utility model. In the claims, description, and accompanying drawings of this utility model, unless otherwise expressly defined, the terms "fixed connection" or "fixed connection" should be interpreted broadly, that is, any connection method in which there is no displacement relationship or relative rotation relationship between the two, that is, including non-removable fixed connection, detachable fixed connection, integral connection, and fixed connection through other devices or elements. In the claims, description, and accompanying drawings of this utility model, the terms "comprising," "having," and their variations are intended to mean "including but not limited to."

[0040] It should be noted that "inner side" refers to the direction of the opening in the server rack, closer to the inside of the rack, while the opposite is "outer side".

[0041] Please refer to the following: Figures 1 to 7The shock-resistant door lock and cabinet provided by this utility model are described below. The shock-resistant door lock includes a drive assembly 3, a latch assembly, and a fixing assembly. The drive assembly 3 is used to connect to the cabinet door. The latch assembly includes multiple latches 2 arranged sequentially at intervals along the inside and outside directions, and the multiple latches 2 are coaxially connected to the drive assembly 3. The fixing assembly includes multiple fixing members 1 arranged sequentially along the inside and outside directions, and the multiple fixing members 1 are all used to connect to the cabinet body. The latches 2 are arranged in a one-to-one correspondence with the fixing members 1. The latches 2 have a locked state when locked with the corresponding fixing member 1 and an unlocked state when separated from the corresponding fixing member 1. The drive assembly 3 is used to drive the multiple latches 2 to rotate synchronously so as to switch the latches 2 between the locked state and the unlocked state.

[0042] Compared with existing technologies, the anti-vibration door lock provided by this utility model utilizes a latch 2 to lock the cabinet door to the cabinet body by engaging with a corresponding fixing member 1. Because multiple latches 2 are provided in both the inner and outer directions, and each latch 2 is equipped with a corresponding fixing member 1, when in the locked state, each latch 2 is engaged with its corresponding fixing member, ensuring the firmness and reliability of the cabinet door and cabinet body lock through multiple locking mechanisms. When the cabinet body vibrates or shakes, if one or more latches 2 are displaced under force, they will switch to the unlocked state with their corresponding fixing member 1, while the other latches 2 remain locked, preventing the cabinet door from separating from the cabinet body after contact with the restraint. This utility model not only improves the reliability of the connection between the cabinet door and cabinet body after locking, but also is simpler than a multi-point lock structure, reducing the space occupied inside the cabinet. In addition, the drive component 3 controls the rotation of multiple latches 2 to switch between the locked and unlocked states. This eliminates the need for intermediate transmission components, simplifying the structure of the anti-vibration door lock and preventing the intermediate transmission components from accidentally touching the latches 2 due to vibration, which would cause the latches 2 to switch to the unlocked state.

[0043] Specifically, when the cabinet door is opened, it rotates outwards from the cabinet body. In the locked state, the locking tongue 2 is located inside the fixing member 1.

[0044] As a specific embodiment of the drive assembly 3, the drive assembly 3 includes a drive shaft connected to a plurality of latches 2 and an operating member connected to the outside of the drive shaft. The operating member is located on the outside of the cabinet door. By rotating the operating member, the drive shaft is driven to rotate, thereby realizing the rotation of the plurality of latches 2.

[0045] Optionally, the operating component has a keyhole, into which a key is inserted and rotated to rotate the operating component.

[0046] It should be noted that the structures of multiple locking tongues 2 can be the same or different. The structures of multiple fasteners 1 can also be the same or different, and no limitation is made here.

[0047] In some embodiments, please refer to Figure 2 and Figure 3 The locking tongue 2 includes a connecting part 201 and a locking part 202. The connecting part 201 is connected to the drive assembly 3. The locking part 202 is connected to the connecting part 201 and is used to lock with the fixing member 1. The locking part 202 includes a locking piece 2023 and a guide flange 2024 connected to the locking piece 2023. The guide flange 2024 is bent inward. In the locked state, the upper and lower sides of the locking piece 2023 are respectively connected to the guide flange 2024.

[0048] Guide flanges 2024 are provided on the upper and lower sides of the locking piece 2023. When the locking piece 2023 switches between the locked and unlocked states, the guide flanges 2024 bend outwards, thereby playing a guiding role. This guides the locking piece 2023 to contact the fixing member 1 at the connection between the locking piece 2023 and the guide flanges 2024. In this embodiment, the resistance generated between the locking piece 2023 and the fixing member 1 when switching between the locked and unlocked states is reduced, avoiding any sense of obstruction caused by the edge of the locking piece 2023 contacting the fixing member 1, which would affect the normal rotation of the locking piece 2023.

[0049] In some embodiments, please refer to Figure 4 The fastener 1 includes a fixing part 101 and a limiting part 102. The fixing part 101 is used to connect with the cabinet. The limiting part 102 includes a limiting piece 1021 connected to the fixing part 101 and an avoidance flange 1022 connected to the fixing part 101. The limiting piece 1021 is connected to the fixing part 101 at an angle. The avoidance flange 1022 bends outward. When the latch 2 switches from the unlocked state to the locked state, the avoidance flange 1022 is used to avoid the latch 2.

[0050] The setting of the avoidance flange 1022 can guide and avoid the rotation of the latch 2, prevent the edge of the limiting piece 1021 from resisting the latch 2 when it comes into contact with the latch 2, and affect the locking or unlocking of the latch 2, thereby reducing the resistance during the locking process.

[0051] In some embodiments, please refer to Figure 5 The fastener 1 also includes a limiting flange 103 connected to the limiting piece 1021. The limiting flange 103 is bent inward and is distributed at an angle with the limiting piece 1021. The limiting flange 103 and the clearance flange 1022 are located on opposite sides of the limiting piece 1021. The limiting flange 103 is used to limit the rotation path of the locking tongue 2.

[0052] After the latch 2 is engaged with the fixing member 1, they abut against each other in the inward and outward directions. However, during the engagement process, if the driving component 3 applies improper force, it may cause the latch 2 to rotate too much, resulting in the latch 2 failing to engage with the fixing member 1. The limiting flange 103 can limit the rotation angle of the latch 2 to prevent the latch 2 from rotating too much. In addition, if subjected to vibration, the latch 2 may also rotate upward, causing it to unlock. In this case, the limiting flange 103 limits the latch 2, keeping the latch 2 in the locked state.

[0053] In some embodiments, please refer to Figure 2 and Figure 6 The locking tongue 2 includes a connecting part 201 and a locking part 202. The connecting part 201 is connected to the drive assembly 3. The locking part 202 is connected to the connecting part 201 and is used to lock with the fixing member 1. The locking part 202 includes a connecting piece 2021 and a locking piece 2022 distributed at an angle. The connecting piece 2021 is connected to the connecting part 201, and the connecting part 201 and the locking part 202 form a "Z" shaped structure. The fixing member 1 has a fixing hole 104. The connecting piece 2021 is inserted into the fixing hole 104, and the locking piece 2022 passes through the fixing hole 104 and is located on the inner side of the fixing member 1.

[0054] In this embodiment, the locking tongue 2 has higher strength than the corresponding straight plate structure, is less prone to deformation, and can effectively resist external forces, increasing the reliability of the locking state. Furthermore, this structure can avoid interference between adjacent locking tongues 2. Since the locking plate 2022 passes through the fixing hole 104 and is located inside the fixing member 1, and the connecting plate 2021 is inserted into the fixing hole 104, the fixing hole 104 can limit the rotation path of the connecting plate 2021, preventing excessive rotation angle of the connecting plate 2021 from affecting the locking of the locking plate 2022 and the fixing member 1.

[0055] Optionally, the fixing hole 104 includes a locking area 1041, a transition area 1042, and an unlocking area 1043 distributed from top to bottom. The locking area 1041 is adapted to the connecting piece 2021, allowing the connecting piece 2021 to rotate only towards the side closer to the transition area 1042. Because the transition area 1042 and the unlocking area 1043 are relatively wide, the locking piece 2022 remains locked when it rotates to the transition area 1042. Therefore, even after being subjected to vibration, even if the latch 2 rotates to the transition area 1042, it can still remain locked, preventing the cabinet door from opening.

[0056] In some embodiments, please refer to Figure 7The fastener 1 includes a locking part 105, a transition part 106 and an unlocking part 107 arranged sequentially from top to bottom. The width of the unlocking part 107 is greater than that of the locking part 105. The transition part 106 forms a smooth transition slope between the locking part 105 and the unlocking part 107. In the locked state, the latch 2 abuts against the locking part 105 in the inward and outward directions. In the unlocked state, the latch 2 rotates to the side of the unlocking part 107.

[0057] Upon being subjected to vibration, the latch 2 rotates. If the latch 2 rotates to the transition section 106, due to the large width of the transition section 106 and the unlocking section 107, the locking plate 2022 remains locked when it rotates to the transition section 106. Therefore, even if the latch 2 rotates to the transition section 106 after being subjected to vibration, it can still remain locked, preventing the cabinet door from opening. In the unlocked state, the latch 2 rotates until it is completely separated from the fixing member 1 and is located on one side of the unlocking section 107.

[0058] In some embodiments, please refer to Figure 7 The fixing member 1 also includes a limiting protrusion 108 provided on the locking part 105. In the locked state, the limiting protrusion 108 abuts against the locking tongue 2 in the vertical direction.

[0059] The limiting protrusion 108 abuts against the locking tongue 2, thereby limiting the rotation of the locking tongue 2 to the side away from the transition part 106, improving the locking stability of the locking and fixing member 1.

[0060] In some embodiments, not shown in the figures, the latch assembly further includes an elastic element connected to the latch 2, the elastic element being configured with a preload to keep the latch 2 in a locked state.

[0061] The latch 2 remains locked under the action of the elastic element, reducing the probability of the latch 2 being passively switched to the unlocked state after being subjected to vibration, thus improving the stability and reliability of the cabinet door and cabinet body locking. When it is necessary to switch the latch 2 to the unlocked state, the drive component 3 controls the latch 2 to overcome the elastic force and switch to the unlocked state.

[0062] Optionally, the elastic element can be a spring or a torsion spring.

[0063] In some embodiments, not shown in the figures, the drive assembly 3 includes a connecting shaft, a driver, and a controller. The connecting shaft is connected to a plurality of locking tongues 2. The driver is connected to the connecting shaft and is used to drive the connecting shaft to rotate around its own axis. The controller is communicatively connected to the driver and is connected to an operating terminal.

[0064] The operator sends commands to the driver via the terminal, which in turn drives the connecting shaft to rotate, thereby controlling the locking tongue 2 to switch between locked and unlocked states. This embodiment requires no manual force and is easy to operate.

[0065] Optionally, the operating terminal can be a mobile phone or access card, or an operating panel. The operating panel can issue commands to the controller using fingerprints or seals.

[0066] Based on the same inventive concept, this utility model also provides a server rack. The server rack includes the aforementioned shock-resistant door lock.

[0067] The cabinet provided by this utility model adopts the aforementioned anti-vibration door lock, which uses the locking tongue 2 to lock the cabinet door to the cabinet body by engaging with the corresponding fixing part 1. Since multiple locking tongues 2 are provided in both the inner and outer directions, and each locking tongue 2 is equipped with a corresponding fixing part 1, when in the locked state, each locking tongue 2 is engaged with the corresponding fixing frame. Multiple locking mechanisms ensure the firmness and reliability of the cabinet door and cabinet body locking. When the cabinet body vibrates or shakes, if one or more locking tongues 2 are displaced under force, they will switch to the unlocked state with the corresponding fixing part 1, while the other locking tongues 2 remain locked, preventing the cabinet door from separating from the cabinet body after contact with the constraint. This utility model not only improves the reliability of the connection between the cabinet door and cabinet body after locking, but is also simpler than a multi-point lock structure, reducing the space occupied inside the cabinet. Furthermore, the drive component 3 controls the rotation of multiple locking tongues 2 to switch between the locked and unlocked states, eliminating the need for intermediate transmission components. This simplifies the structure of the anti-vibration door lock and avoids the intermediate transmission components accidentally engaging the locking tongues 2 due to vibration, causing the locking tongues 2 to switch to the unlocked state.

[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
