Description

Technical Field

[0001] This utility model relates to the field of locks, and more specifically, to a locking structure and system. Background Technology

[0002] Locks are devices that serve a sealing function, enabling the locking of two components of a locked device. A switch cabinet is an electrical device where external power lines enter the cabinet to connect to circuit breakers, relays, and various AC contactors. Because the safety of high and low voltage electrical conduction is crucial, a locking device must be installed between the cabinet door and the cabinet body to ensure the safety of the switch cabinet.

[0003] Many existing interlocking devices are electrically operated for unlocking and locking, which are relatively complex in structure, difficult to maintain, and costly. Furthermore, they cannot be used after a power outage, thus affecting the usability of the switch cabinet structure and causing inconvenience. Utility Model Content

[0004] The present invention aims to overcome at least one defect (deficiency) of the prior art and provide a locking structure and system that is low in cost.

[0005] One object of this utility model is to provide a locking structure, comprising:

[0006] A locking element is provided on the first component of the locking device;

[0007] A snap-fit ​​body, disposed on the second component of the locking device, and comprising:

[0008] The base is connected to the second component;

[0009] The sliding block is slidably connected inside the base;

[0010] The elastic mechanism has one end connected to the base and the other end connected to the sliding block. The end of the sliding block away from the elastic mechanism is provided with a locking part. The locking part engages with the locking part to lock the first component and the second component.

[0011] A manual actuation mechanism is connected to a sliding block drive to drive the sliding block to move along a first direction and compress the elastic mechanism, causing the locking part to disengage from the locking member, thereby unlocking the first and second components.

[0012] In this technical solution, when the manual actuation mechanism is subjected to force, it can drive the sliding block to slide along the first direction. After the locking part disengages from the locking member and completes the unlocking, the elastic mechanism changes from the compressed state to the extended state, which will push the sliding block to move along the second direction, which is the opposite direction to the first direction.

[0013] The actuation mechanism in this solution is manual, allowing users to unlock it manually without being affected by power outages, thus ensuring the normal operation of the locked device. In addition, the locking device in this solution has a simple structure, is easy to maintain, and has low cost.

[0014] Furthermore, the locking part includes a locking surface and a locking surface; the locking member is provided with a locking part, and the locking surface locks the locking part to realize the locking of the locking structure; the locking surface is inclined in a first direction, and the locking surface is parallel to the first direction.

[0015] When the locking structure needs to be tightened, the first component is moved, causing the locking member to push and compress the locking surface. The sliding block moves in the first direction, and the elastic mechanism gradually compresses until the locking part disengages from the locking surface. The elastic mechanism then extends and retracts to reset, and the sliding block moves in the second direction. The locking surface then engages the locking part, and the locking structure is tightened. The locking part may or may not be in contact with the locking surface, as long as the locking part can engage the locking part.

[0016] The locking surface is angled to facilitate the locking part pushing and squeezing the locking part, so that when the locking part squeezes the locking surface, the locking part moves in the first direction. If the locking surface is angled in the first direction, it may either hook the locking part and affect unlocking, or the locking may be too loose and easily lead to mis-locking. Therefore, setting the locking surface parallel to the first direction can firmly lock the locking part without affecting the sliding block's sliding unlocking in the first direction.

[0017] Furthermore, the connection between the locking surface and the snap-fit ​​surface is rounded.

[0018] In this technical solution, if the connection between the two surfaces is a sharp corner, the sharp corner is prone to breakage when the locking part pushes and squeezes the locking surface to disengage from it, affecting the degree of locking. Therefore, the connection between the two surfaces is rounded, allowing the locking part to disengage from the locking surface more smoothly.

[0019] Furthermore, the manual actuation mechanism is rotatably connected to the base and is provided with a driving protrusion. The sliding block is provided with a force-receiving protrusion. When the manual actuation mechanism is rotated under force, the driving protrusion pushes the force-receiving protrusion to move along the first direction, so as to realize that the sliding block moves in the first direction.

[0020] Furthermore, the sliding block is provided with two force-receiving protrusions, and the line connecting the two force-receiving protrusions is perpendicular to the first direction. The manual actuation mechanism is provided with two driving protrusions for driving the two force-receiving protrusions respectively.

[0021] In this technical solution, two force-bearing protrusions are set on both sides of the base, and two driving protrusions correspond to the two force-bearing protrusions respectively. When the user rotates the manual actuation mechanism, it can rotate clockwise, with one driving protrusion driving its corresponding force-bearing protrusion, or it can rotate counterclockwise, with the other driving protrusion driving its corresponding force-bearing protrusion, making unlocking more convenient.

[0022] Furthermore, when the manual actuation mechanism is in a state of waiting to be applied, the driving cam and the applied cam come into contact.

[0023] In this technical solution, the manual actuation mechanism being in a state of waiting to be applied force can be understood as being in a state of not being driven by force. The contact between the driving protrusion and the force-receiving protrusion allows the driving protrusion to immediately drive the force-receiving protrusion once the manual actuation mechanism rotates, thus preventing free spin. For users, this improves unlocking efficiency and optimizes the user experience; for businesses, it enhances the quality of the locking structure, increases sales, and boosts revenue.

[0024] Furthermore, the manual actuation mechanism is a cylinder with a bottom step at one end, which is rotatably connected to the base; the other end has a lock hole groove.

[0025] In this technical solution, the keyhole groove is used with an unlocking tool, such as a key. After the key is inserted into the keyhole groove and rotated, the manual actuation mechanism is rotated under force. The bottom step can save materials and reduce costs.

[0026] Furthermore, one end of the sliding block connecting the spring is provided with a notch, and the spring is connected to the notch.

[0027] In this technical solution, a portion of the spring connected to one end of the sliding block is located within a recess. This prevents the spring from bending during compression, especially when the spring is long, thus allowing the sliding block to rebound normally and ensuring the normal use of the locking structure.

[0028] Another objective of this utility model is to provide a locking system, including a first component and a second component, and further including any of the above-mentioned locking structures, wherein the locking member is connected to the first component and the locking body is connected to the second component.

[0029] Furthermore, the locking system is a switch cabinet, the first component is the cabinet door, and the second component is the cabinet body.

[0030] Compared with the prior art, the advantages of this utility model are as follows: the actuation mechanism of this utility model is manual, and the user can unlock it manually without being affected by power failure, ensuring the normal use of the locked device; in addition, the locking device of this utility model has a simple structure, low maintenance difficulty, and low cost.

[0045] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0046] Example 1

[0047] refer to Figures 1-6 This embodiment provides a locking structure, including:

[0048] The locking component 100 is disposed on the first component 600 of the locking device;

[0049] The snap-fit ​​body 200 is disposed on the second component 700 of the locking device and includes:

[0050] The base 300 is connected to the second component 700;

[0051] Sliding block 400 is slidably connected to base 300;

[0052] The elastic mechanism 410 has one end connected to the base 300 and the other end connected to the sliding block 400. The sliding block 400 has a locking part 420 at the end away from the elastic mechanism 410. The locking member 100 engages with the locking part 420 to lock the first component 600 and the second component 700.

[0053] The manual actuation mechanism 500 is driven to connect with the sliding block 400 to drive the sliding block 400 to move along the first direction A and compress the elastic mechanism 410. The locking part 420 disengages from the locking member 100, thereby unlocking the first component 600 and the second component 700.

[0054] The structure of the base 300 will be described next.

[0055] refer to Figures 7 to 9 For example, the base 300 includes a mounting base 310 and a mounting cover 320. The mounting base 310 has an opening, and the mounting cover 320 closes the opening. The two are detachably connected, for example, by a threaded connection, to facilitate maintenance of the internal structure. The elastic mechanism 410 and the sliding block 400 are both located within the mounting base 310. The mounting base 310 and the mounting cover 320 have corresponding positioning holes 311. The manual actuation mechanism 500 passes through the positioning holes 311 and is rotatably connected to the mounting base 310. The mounting base 310 has a locking slot 312, through which the locking member 100 passes and engages with the locking part 420.

[0056] The following describes the relevant structure of the card connector.

[0057] refer to Figure 6 To facilitate locking operations, the locking part 420 includes a locking surface 421 and a locking surface 422 connected together; the locking member 100 is provided with a locking part 110, and the locking surface 422 locks the locking part 110 to achieve locking of the locking structure; the locking surface 421 is inclined to the first direction A, and the locking surface 422 is parallel to the first direction A.

[0058] refer to Figures 1 to 3 and Figure 6 When the locking structure needs to be locked, the first component 600 is moved so that the locking member 100 pushes and compresses the locking surface 421. The sliding block 400 moves in the first direction A, and the elastic mechanism 410 gradually compresses until the locking part 110 disengages from the locking surface 421. The elastic mechanism 410 then extends and retracts to its original position, the sliding block 400 moves in the second direction B, and the locking surface 422 locks the locking part 110, thus locking the structure. This allows the locking device to be locked without the need for other tools, greatly improving convenience. The locking part 110 may or may not be in contact with the locking surface 422, as long as the locking part 420 can lock the locking part 110. The locking surface 421 is inclined to facilitate the locking part 110 pushing and compressing the locking part 420. When the locking part 420 compresses the locking surface 421, the locking part 420 moves in the first direction A. If the engaging surface 422 is inclined to the first direction A, it will either affect unlocking because it hooks onto the locking part 420, or it may cause mis-locking because the engagement is too loose. Therefore, setting the engaging surface 422 parallel to the first direction A can firmly lock the locking part 420 without affecting the sliding block 400 sliding to unlock in the first direction A. Specifically, the angle between the inclined surface and the engaging surface 422 is 40° to 60°.

[0059] refer to Figures 1 to 3 For example, the locking part 420 also includes a locking surface 422, which is also parallel to the first direction A. When the locking part 420 is engaged with the locking member 100, the two locking surfaces 422 of the locking part 420 and the locking part 110 are matched and contacted. In this way, when locked, there will be no gap between the locking part 420 and the locking part 110, and there will be no loosening between them. There will also be no gap between the first component 600 and the second component 700, thereby better protecting the internal structure of the locked device.

[0060] refer to Figure 6 To reduce the probability of damage, the connection between the locking surface 421 and the latching surface 422 is rounded. If the connection between the two surfaces were sharp, the sharp corner would easily break under pressure when the latching part 110 pushes and squeezes the locking surface 421 and then disengages from it, affecting the locking tightness. Therefore, by setting the connection between the two surfaces to a rounded corner, the latching part 110 can disengage from the locking surface 421 more smoothly.

[0061] The following describes the relevant structures of the manual actuation mechanism 500 and the sliding block 400.

[0062] refer to Figure 10 and Figure 11 The manual actuation mechanism 500 is rotatably connected to the base 300 and is provided with a driving protrusion 520. The sliding block 400 is provided with a force-receiving protrusion 430. When the manual actuation mechanism 500 is rotated under force, the driving protrusion 520 pushes the force-receiving protrusion 430 to move along the first direction A, so as to realize that the sliding block 400 moves in the first direction A.

[0063] When the manual actuation mechanism 500 is not driven, the elastic element can be in a fully reset state or in a slightly compressed state. When the elastic element is in the latter state, the driving protrusion 520 also limits the force-bearing protrusion 430 to prevent the sliding block 400 from continuing to slide in the second direction B.

[0064] To facilitate unlocking, the sliding block 400 is provided with two force-receiving protrusions 430. Specifically, the line connecting the two force-receiving protrusions 430 is perpendicular to the first direction A. The manual actuation mechanism 500 is provided with two driving protrusions 520, which are used to drive the two force-receiving protrusions 430 respectively. It can be understood that the two force-receiving protrusions 430 are located on both sides of the sliding block 400, and the two driving protrusions 520 correspond to the two force-receiving protrusions 430 respectively. Thus, when the user rotates the manual actuation mechanism 500, it can rotate clockwise, causing one driving protrusion 520 to drive its corresponding force-receiving protrusion 430, or it can rotate counterclockwise, causing the other driving protrusion 520 to drive its corresponding force-receiving protrusion 430, making unlocking more convenient.

[0065] To further facilitate unlocking, when the manual actuation mechanism 500 is in a ready-to-be-forced state, the driving protrusion 520 and the force-receiving protrusion 430 are in contact. The ready-to-be-forced state of the manual actuation mechanism 500 can be understood as a state where it is not being driven by force. The contact between the driving protrusion 520 and the force-receiving protrusion 430 ensures that once the manual actuation mechanism 500 rotates, the driving protrusion 520 can immediately drive the force-receiving protrusion 430, thus preventing free-spinning. For users, this improves unlocking efficiency and optimizes the user experience; for businesses, it enhances the quality of the locking structure, increases sales, and boosts revenue.

[0066] Specifically, the manual actuation mechanism 500 is a cylinder with a bottom step 510, which is rotatably connected to the mounting base 310. The other end has a top step and a keyhole groove 530, with the top step rotatably connected to the mounting cover 320. Both the bottom step 510 and the top step are cylindrical, facilitating the rotation of the manual actuation mechanism 500. The keyhole groove 530 is used with an unlocking tool, such as a key. Inserting the key into the keyhole groove 530 causes rotation, thus rotating the manual actuation mechanism 500. More specifically, the sliding block 400 has a movable area 450 in the middle, through which the manual actuation mechanism 500 passes and is connected to the mounting base 310 via the bottom step 510.

[0067] refer to Figure 11 To improve the sliding stability of the sliding block 400, a notch 440 is provided at one end of the sliding block 400 connected to the spring, and the spring is connected within the notch 440. A portion of the spring connected to the sliding block 400 is located within the notch 440. This prevents the spring from bending during compression, especially when the spring is long, thus allowing the sliding block 400 to rebound normally and ensuring the normal use of the locking structure.

[0068] The working principle of the locking structure in this embodiment is:

[0069] refer to Figures 1 to 3 When locking is required, the first component 600 is moved, causing the locking part 110 to push and compress the locking surface 421. The locking part 110 drives the entire sliding block 400 to slide in the first direction A. The elastic mechanism 410 is gradually compressed until the locking part 110 disengages from the locking surface 421. The elastic mechanism 410 extends and resets, and the locking part 420 moves in the second direction B. The locking surface 422 locks the locking part 420, thus locking the first component 600 and the second component 700.

[0070] When unlocking is required, the user inserts a lock-picking tool into the lock slot 530 and rotates it to make the manual actuation mechanism 500 rotate, driving the protrusion 520 to push the force-receiving protrusion 430. The force-receiving protrusion 430 drives the entire sliding block 400 to slide in the first direction A, the locking part 420 moves in the first direction A, the elastic mechanism 410 is compressed, and the locking part 110 disengages from the locking surface 422, thereby unlocking the first component 600 and the second component 700.

[0071] Example 2

[0072] refer to Figure 12 and Figure 13 This embodiment provides a locking system, including a first component 600, a second component 700, and a locking structure provided in Embodiment 1. The locking member 100 is connected to the first component 600, and the locking body 200 is connected to the second component 700.

[0073] For example, the locking system is a switch cabinet, the first component 600 is the cabinet door, the second component 700 is the cabinet body, and the first component 600 and the second component 700 are hinged together by a hinge 610.
