[0029] In the description of this embodiment, unless otherwise explicitly limited, terms such as setting, installing, and connecting should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this embodiment in conjunction with the specific content of the technical solution.
[0030] Reference Figures 1 to 8 This describes the implementation of the double-opening rotary lock 100 and the storage tool 200. It should be noted that... Figure 2 For ease of illustration, the second mounting housing 111 of the mounting base 101 has been removed. Figure 3 In the diagram, the first locking part 102 is shown in the locked position 300. For clarity, the sectional view has been rotated 90° clockwise. Furthermore, only the essential parts are shown in the sectional view; some structural sections are not cut open. Figure 4 For illustrative purposes, the correspondence is not strictly defined. Figure 1 Instead of showing a cross-sectional view, it indicates the unlock position 400. Furthermore, similarly, only the main part is cut out.
[0031] The double-opening rotary lock 100 of the embodiment includes: a mounting base 101, a first locking part 102 and a second locking part 103.
[0032] Main reference Figures 1 to 4 The mounting base 101 is used to install the first lock part 102 and the second lock part 103. In addition, the mounting base 101 is also used to install the double-opening rotary lock 100 as a whole into a storage tool 200 such as a filing cabinet or drawer.
[0033] The first locking part 102 includes a first housing 146, a lock cylinder 104, and a first bolt 105. The first housing 146 has a rotating portion 106 and a locking portion 107 formed on its outer side. The first locking part 102 is mounted to the mounting base 101 via the rotating portion 106. The lock cylinder 104 is housed within the first housing 146 and can rotate relative to the first housing 146 when unlocked using a corresponding key (not shown). The first bolt 105 is located outside the first housing 146 and is connected to the lock cylinder 104. When the lock cylinder 104 is not unlocked, the first bolt 105 is fixed relative to the first housing 146. When the lock cylinder 104 is unlocked, the first bolt 105 can rotate between a locked position 300 and an unlocked position 400 as the lock cylinder 104 rotates. Here, the locked position 300 refers to the position where the double-opening rotary lock 100 restricts the opening of the door 201 (e.g., the door 201 of a filing cabinet) or drawer (e.g., a drawer of a table) of the storage tool 200 when it is installed on the storage tool 200, and the unlocked position 400 refers to the position where the double-opening rotary lock 100 allows the door 201 or drawer of the storage tool 200 to be opened.
[0034] The second locking part 103 includes a driving member 108 and a second locking tongue 109. The second locking tongue 109 is connected to the driving member 108 and can be extended or retracted by the driving member 108. The second locking part 103 is mounted to the mounting base 101 such that the second locking tongue 109 can be opposite to the locking part 107. When the second locking tongue 109 is extended by the driving member 108, the second locking tongue 109 is locked to the locking part 107, and the first locking part 102 is fixed relative to the mounting base 101 (see reference). Figure 3 When the second locking tongue 109 is retracted relative to the locking part 107 by the drive member 108, the first locking part 102 rotates relative to the mounting base 101 via the rotating part 106 (see reference). Figure 4 This allows the first locking tongue 105 to rotate between the locked position 300 and the unlocked position 400.
[0035] The double-locking rotary lock 100 of this embodiment provides additional unlocking methods based on the original mechanical lock, making it convenient for authorized users to unlock. Specifically, the lock cylinder 104 of the first locking part 102 of the double-locking rotary lock 100 can be a known lock cylinder 104 that can be opened with a physical key. When a suitable key is inserted and turned, the lock cylinder 104 can rotate, and the first bolt 105 rotates with the lock cylinder 104, thereby enabling the first locking part 102 to lock or unlock (that is, this is the first unlocking method of the double-locking rotary lock 100 of this embodiment).
[0036] Furthermore, since the first outer shell 146 of the first lock part 102 is mounted to the mounting base 101 via the rotating part 106, and the first outer shell 146 has a locking part 107, when the locking part 107 is locked by the second locking tongue 109 of the second lock part 103, the entire first lock part 102 is fixed on the mounting base 101, and at this time it can only be unlocked by the first unlocking method (i.e., it can only be unlocked by a key).
[0037] When the second latch 109 retracts relative to the locking part 107 by unlocking the second lock part 103, the first lock part 102 can rotate relative to the mounting base 101 via the rotating part 106. At this time, even without using the key of the first lock part 102, when the first lock part 102 is rotated as a whole relative to the mounting base 101, the first latch 105 of the first lock part 102 can switch between the locked position 300 and the unlocked position 400 as the first lock part 102 rotates as a whole, thereby achieving unlocking (that is, this is the second unlocking method of the double-opening rotary latch lock 100 of the embodiment).
[0038] Therefore, in this embodiment of the double-opening rotary lock 100, for example, the second unlocking method can be used as the main unlocking method, and the first unlocking method can be used as a backup unlocking method. The key of the first lock part 102 is handed over to a special custodian for safekeeping. Thus, it is convenient for other users with authorization but without the key of the first lock part 102 to unlock the lock.
[0039] Continue to refer to Figure 7 as well as Figure 8 In this embodiment, the double-opening rotary latch 100 is mounted to, for example, the door 201 of a storage tool 200 via a mounting base 101. For example, a mounting groove (not shown) can be provided in the door 201 of the storage tool 200, and the mounting base 101 of the double-opening rotary latch 100 can be fitted into the mounting groove. The mounting base 101 includes a first mounting housing 110 and a second mounting housing 111 that are mutually captive. The first mounting housing 110 is fitted into the mounting groove from one side of the door 201, and the second mounting housing 111 is fitted into the mounting groove from the other side of the door 201 and caps onto the first mounting housing 110. Then, the first mounting housing 110 and the second mounting housing 111 are locked together from one side of the second mounting housing 111 using screws or the like, thereby fixing the double-opening rotary latch 100 to the door 201 in such a way that the first mounting housing 110 and the second mounting housing 111 together clamp the door 201 of the storage tool 200.
[0040] Continue to refer to Figures 3 to 6The first locking part 102 is installed into the mounting hole 112 of the first mounting housing 110 of the mounting base 101. More specifically, the rotating part 106 of the first outer shell 146 of the first locking part 102 is inserted into the mounting hole 112 of the first mounting housing 110. Without being blocked by the second latch 109 of the second locking part 103, the first locking part 102 can rotate around the mounting hole 112 of the first mounting housing 110. The first outer shell 146 of the first locking part 102 is generally stepped shaft-shaped, and a receiving cavity 113 is formed inside the first outer shell 146, extending axially. The lock cylinder 104 is installed in the receiving cavity 113 using a known mechanical lock mounting method. A knob part 114 with an outer diameter larger than the rotating part 106 is formed at one axial end of the first outer shell 146. The knob part 114 is integrally formed on the first outer shell 146 and serves as a gripping part for rotating the first locking part 102. With the first lock part 102 installed in the mounting base 101, the knob part 114 is located on the outside of the first mounting housing 110. The keyhole 115 of the lock cylinder 104 is located on one side of the knob part 114 of the first housing 146, that is, whether the first lock part 102 is unlocked using a key or the first lock part 102 is turned directly, it is done on one side of the knob part 114. The rotating part 106 is integrally and coaxially formed with the knob part 114 at the other end of the axial direction of the first housing 146. The rotating part 106 is, for example, generally cylindrical. When installed in the mounting hole 112 of the first mounting housing 110, the rotating part 106 at the other end of the axial direction of the first housing 146 is inserted into the mounting base 101, while the knob part 114 at one end of the axial direction of the first housing 146 abuts against the end face of the mounting hole 112, and restricts the first housing 146 from being further inserted into the mounting hole 112 of the mounting base 101 along one end of the axial direction.
[0041] The locking portion 107 of the first outer casing 146 can be formed on the outer peripheral surface of the rotating portion 106. For example, the locking portion 107 can be a groove 116 formed on the outer peripheral surface of the rotating portion 106. The shape of the groove 116 is not particularly limited, and can be, for example, a circular shape, a square shape, an elliptical shape, etc. Furthermore, the groove 116 can penetrate the first outer casing 146 radially along the rotating portion 106. When the groove 116 penetrates the first outer casing 146, it can also be regarded as the first outer casing 146 having two grooves 116, one located on one radial side of the rotating portion 106 and the other located on the other radial side of the rotating portion 106. By forming two grooves 116 on the rotating portion 106, the double-opening rotary latch 100 can be appropriately adjusted according to the unlocking scenario. For example, when the first locking tongue 105 rotates clockwise from the locked position 300 to the unlocked position 400, one of the slots 116 can be used to restrict the first locking part 102 circumferentially; when the first locking tongue 105 rotates counterclockwise from the locked position 300 to the unlocked position 400, the other slot 116 can be used to restrict the first locking part 102 circumferentially.
[0042] The first housing 146 may have a limiting portion 117 formed on its outer side, with the limiting portion 117 and the locking portion 107 distributed circumferentially around the first housing 146. When the second latch 109 is extended and the first locking portion 102 is in the unlocked position 400, the second latch 109 abuts against the limiting portion 117 to hold the first locking portion 102 in the unlocked position 400. The limiting portion 117 temporarily restricts the first locking portion 102, preventing it from swinging freely around the mounting base 101 when it is in the unlocked position 400. The limiting portion 117 may also be a limiting groove 118 formed on the outer peripheral surface of the rotating portion 106, for example, formed at a 90° circumferential interval from the locking groove 116. Furthermore, two limiting grooves 118 may be provided and distributed approximately 180° circumferentially around the rotating portion 106. The depth of the limiting groove 118, which serves as a temporary restriction function, is shallower than the depth of the slot 116. Furthermore, guide surfaces 119 can be formed on both sides of the limiting groove 118 along the circumference of the rotating part 106. When the second latch 109 is inserted into the limiting groove 118, as the first housing 146 rotates, the second latch 109 abuts against the guide surface 119 and retracts as the first housing 146 rotates further, thereby releasing the restriction on the rotation of the first housing 146.
[0043] The first latch 105 of the first lock part 102 can be a long, strip-shaped sheet metal part. One end of the first latch 105 is connected to the lock cylinder 104 at the rotating part 106 of the first housing 146. That is, when the mounting base 101 is installed on the door 201, the knob part 114 (one side of the keyhole 115) of the first lock part 102 is located on the outside of the door 201 (the open side), and the first latch 105 is located on the inside of the door 201 (the closed side). The first lock part 102 can also have a connecting shaft 120. One end of the connecting shaft 120 is inserted into the first housing 146 and connected to the lock cylinder 104, and the other end of the connecting shaft 120 is located on the outside of the first housing 146 and connected to the first latch 105. In other words, the first latch 105 can be connected to the lock cylinder 104 via the connecting shaft 120.
[0044] The connecting shaft 120 is a hollow shaft-shaped component. One axial end of the connecting shaft 120 has a countersunk hole 121 for a screw to pass through, and the other axial end has an internally threaded hole 122 for mounting a screw. For example, the countersunk hole 121 can be machined on the connecting shaft 120 first, and then the large-diameter end of the countersunk hole 121 can be tapped to form the internally threaded hole 122. The end of the connecting shaft 120 with the countersunk hole 121 is used to fix the connecting shaft 120 to the lock cylinder 104 using, for example, an internal hexagon head screw. The other end of the connecting shaft 120 with the internally threaded hole 122 is used to lock the first locking tongue 105 onto the connecting shaft 120 using, for example, an internal hexagon head screw. Both ends of the connecting shaft 120 in the axial direction can be formed with various known flat fit structures. Through such flat fit structures, it is ensured that when the connecting shaft 120 is connected to the lock cylinder 104 or when the first lock tongue 105 is installed, the first lock tongue 105 will not be offset circumferentially relative to the lock cylinder 104 due to loose screws, etc.
[0045] A flange 123 is formed at the axial center of the connecting shaft 120. The outer diameter of the flange 123 is larger than the outer diameter of the rotating part 106 of the first housing 146, and also larger than the inner diameter of the mounting hole 112. When the first locking part 102 is installed onto the mounting base 101, the connecting shaft 120 is connected to the lock cylinder 104 from the other axial end of the first housing 146 (i.e., the end opposite to the knob part 114), and the first locking part 102 is installed onto the mounting base 101 such that the connecting shaft 120 and the knob part 114 of the first housing 146 jointly clamp the mounting base 101. Specifically, the first locking part 102 is mounted to the mounting base 101 by clamping the mounting base 101 together with the flange part 123 of the connecting shaft 120 and the knob part 114 of the first housing 146. Thus, the first locking part 102 is axially restricted relative to the mounting base 101. However, the first locking part 102 can rotate relative to the mounting base 101 about the mounting hole 112 without being restricted by the second locking tongue 109 of the second locking part 103. Furthermore, it should be noted that in order to allow the first locking tongue 105 to rotate smoothly, there can be a certain axial gap between the flange part 123 of the connecting shaft 120, the knob part 114 of the first housing 146, and the mounting base 101 (the first mounting housing 110).
[0046] Continue to refer to Figure 5 as well as Figure 6 and supplementary reference Figure 2 Additionally, a first protrusion 124 protruding radially may be formed on the circumferential edge of the flange portion 123 of the connecting shaft 120. Correspondingly, a second protrusion 125 may be formed on the mounting base 101 (e.g., the first mounting housing 110) at a position corresponding to the flange portion 123 of the connecting shaft 120. The second protrusion 125 may include two locations, one located on one radial side of the mounting hole 112 in the mounting base 101, and the other located on the other radial side of the mounting hole 112. When the connecting shaft 120 rotates relative to the first housing 146 or the first locking part 102 rotates entirely relative to the mounting base 101, the first protrusion 124 abuts against one of the second protrusions 125, thereby limiting the rotation angle of the connecting shaft 120. That is, the position where the first protrusion 124 abuts against the second protrusion 125 is the locked position 300 of the first locking part 102.
[0047] Continue to refer to Figure 3 as well as Figure 4 and supplementary reference Figure 6 The first locking part 102 can be installed into the mounting base 101 in the following manner, for example.
[0048] First, without the connecting shaft 120 and the first locking tongue 105 installed, insert one end of the rotating part 106 of the first housing 146 into the mounting hole 112 of the first housing 110 from one side of the first mounting housing 110 of the mounting base 101.
[0049] Then, the end of the connecting shaft 120 with the countersunk hole 121 formed from the rotating part 106 of the first housing 146 is inserted into the receiving cavity 113 of the first housing 146.
[0050] Next, insert the hex socket head cap screw into the end of the connecting shaft 120 with the internal threaded hole 122 until it reaches the countersunk hole 121. Then, align the flat structure of the connecting shaft 120 with the flat structure of the lock cylinder 104, and tighten the hex socket head cap screw into the lock cylinder 104 using an Allen wrench. Thus, the connecting shaft 120 is fixed to the lock cylinder 104. At this time, the flange portion 123 of the connecting shaft 120 and the knob portion 114 of the first housing 146 together clamp the first mounting housing 110, thereby preventing the first locking part 102 from falling off axially.
[0051] Next, the second mounting housing 111 is locked to the first mounting housing 110 such that one end of the connecting shaft 120 with the internal threaded hole 122 protrudes through the second mounting housing 111. To allow the connecting shaft 120 to protrude through the second mounting housing 111, a clearance hole (not marked in the attached drawing) may be provided on the second mounting housing 111.
[0052] Then, on the outer shell of the second mounting housing 111, the first locking tongue 105 is aligned with the end of the connecting shaft 120 that has an internal threaded hole 122, and then the first locking tongue 105 is locked.
[0053] Thus, the installation of the first lock part 102 can be completed.
[0054] Continue to refer to Figure 3 , Figure 4 And supplementary reference Figure 2 The second locking part 103 is installed into the receiving groove 126 of the first mounting housing 110, and the mounting hole 112 communicates with the receiving groove 126. With the second latch 109 of the second locking part 103 extended and the first locking part 102 in the locked position 300, the second latch 109 is inserted into the slot 116. That is, by inserting the second latch 109 into the slot 116 of the first locking part 102, the second locking part 103 keeps the first locking part 102 in the locked position 300 when unlocking without a key.
[0055] The second locking part 103 can be installed as a separate component into the storage slot 126, or each component can be installed separately into the storage slot 126. While the unlocking method of the second locking part 103 is not particularly limited, it is preferable that the second locking part 103 uses a different unlocking method than the first locking part 102. For example, since the first locking part 102 uses a physical key, the second locking part 103 can be unlocked using a non-physical unlocking method. The driving component 108 of the second locking part 103 can be a motor 127. The unlocking part 128 of the second locking part 103 is electrically connected to the motor 127, causing the motor 127 to operate, thereby driving the second locking tongue 109 to extend or retract.
[0056] As a non-physical unlocking method that causes the motor 127 to operate, thereby extending or retracting the second latch 109, methods such as facial recognition, iris recognition, fingerprint recognition, password input, NFC recognition, and Bluetooth recognition can be listed. To unlock using these non-physical unlocking components, the unlocking unit 128 may include at least one of a feature recognition unit, a password recognition unit, an NFC recognition unit, and a Bluetooth recognition unit. As a feature recognition unit, examples include those used to recognize features such as a user's face, iris, or fingerprint. As a password recognition unit, examples include those that recognize a fixed password entered on the unlocking panel 129, or a fixed password or random password obtained by the user through scanning a QR code with a mobile phone. As an NFC (Near Field Communication) recognition unit, an RFID recognition function unit can be mounted on the second lock unit 103, and correspondingly, an RFID recognition function unit for unlocking can be mounted on a mobile phone or similar device. As a Bluetooth recognition unit, for example, authorized users can use Bluetooth wireless technology to connect to the locked Bluetooth recognition unit via a mobile phone or similar device to unlock the door. These identification units are mounted on, for example, the unlocking panel 129, and the unlocking panel 129 is embedded in the first mounting housing 110, thereby facilitating authorized users to operate and unlock the second lock unit 103. Any of these feature identification units, password identification units, NFC identification units, and Bluetooth identification units as unlocking methods are existing technologies and will not be described in detail here.
[0057] In the double-opening rotary lock 100 of the embodiment, by using the second lock part 103 with this non-physical unlocking method to lock the first lock part 102, more unlocking methods can be provided, and more unlocking methods can be provided for other legitimate users. In addition, since the key of the first lock part 102 is kept by a dedicated custodian, the double-opening rotary lock 100 can be opened in emergency situations (such as when the second lock part 103 is powered off).
[0058] The second locking unit 103 generally includes a main body 130, an unlocking unit 128, and a battery 131. The unlocking unit 128 of the second locking unit 103 includes an unlocking panel 129 and a control panel (not shown). The unlocking panel 129 is located on one side of the knob 114 and is embedded in the first mounting housing 110, while the control panel is housed in a storage slot 126. In a specific example, the unlocking panel 129 has a digital password input button as a password recognition unit and / or a fingerprint input glass piece as a feature recognition unit. By using such a digital password input button and / or fingerprint input button, the double-opening rotary lock 100 can be made more compact and less expensive, making it particularly suitable for applications such as filing cabinets or desks (office desks) used in office spaces. The control panel and battery 131 are also housed in the storage slot 126. The unlocking panel 129, motor 127, battery 131, etc., are electrically connected to the control board, so that when the correct password or fingerprint is entered from the unlocking panel 129, the motor 127 of the main body 130 can be controlled to work, thereby driving the second bolt 109 to extend or retract. As for the connection method and control logic of the unlocking panel 129, motor 127, battery 131, etc. and the control board, the connection method and control logic of known electronic locks can be used, and will not be described in detail here.
[0059] Continue to refer to Figure 7 And supplementary reference Figure 3 as well as Figure 4 In the embodiment of the double-locking rotary lock 100, the main body 130 of the second locking part 103 is configured according to the first locking part 102 to keep the first locking part 102 in the locked position 300, or to release the restriction on the first locking part 102 so that the first locking part 102 can be rotated as a whole to the unlocked position 400.
[0060] In a specific example, the main body 130 of the second locking part 103 includes a second housing 132, through which the main body 130 of the second locking part 103 is fixed to the mounting base 101. The second housing 132 is generally cylindrical and has a circular mounting chamber 133. One axial end of the second housing 132 has a non-circular connecting hole 134, which connects to and communicates with the mounting chamber 133 to the outside. The other axial end of the second housing 132 is through-hole, thereby facilitating the installation of the second locking tongue 109 and the motor 127, etc. Specifically, in addition to the second locking tongue 109 and the motor 127, the main body 130 also includes a drive sleeve 135 and an elastic member 136. After housing the second locking tongue 109, drive sleeve 135, elastic element 136 and motor 127, the mounting chamber 133 of the second housing 132 is covered by a cover plate 137 at the other axial end of the second housing 132 to prevent these components from falling out.
[0061] Overall, within the mounting chamber 133 of the second housing 132, the motor 127 is connected to the second locking tongue 109 via the drive sleeve 135. When the drive sleeve 135 is rotated by the motor 127, the second locking tongue 109 extends or retracts relative to the drive sleeve 135.
[0062] As described above, a non-circular connecting hole 134 is formed on the second housing 132. This connecting hole 134 is used for the second latch 109 to pass through. In addition, the connecting hole 134 also restricts the rotation of the second latch 109, so that the rotational motion of the motor 127 can be converted into the linear motion of the second latch 109. The output shaft of the motor 127 is connected to the second latch 109 via a drive sleeve 135. A cam structure 138 is formed between one axial end of the drive sleeve 135 and the second latch 109. When driven by the rotation of the motor 127, the drive sleeve 135 rotates around the mounting chamber 133. The shape of the other axial end of the second latch 109 is adapted to the connecting hole 134 and extends out of the second housing 132 through the connecting hole 134.
[0063] Specifically, the second latch 109 is generally axial, and a cylindrical portion 139 is formed at one axial end of the second latch 109. A radially extending pin 140 is provided on the cylindrical portion 139 of the second latch 109. For example, a pin hole (not marked in the figure) can be opened on the cylindrical portion 139 of the second latch 109, and then the pin 140 can be inserted into the pin hole.
[0064] An insertion hole 141 is formed at one axial end of the drive sleeve 135. The insertion hole 141 allows the cylindrical portion 139 of the second locking tongue 109 to be inserted, and the cylindrical portion 139 of the second locking tongue 109 can rotate freely within the insertion hole 141. A cam groove 142 is formed on the wall of the drive sleeve 135, extending circumferentially along the wall of the drive sleeve 135. The cam groove 142 has a cam surface 143, which is formed to extend circumferentially along the wall of the drive sleeve 135 and extend axially toward the insertion hole 141. Furthermore, the cam groove 142 has a limiting surface 144 located on the other axial side of the cam surface 143, and the limiting surface 144 is substantially parallel to the end face of the drive sleeve 135. Thus, the cam groove 142 is formed such that while it extends circumferentially along the wall of the drive sleeve 135, the width of the groove along the axial direction of the drive sleeve 135 gradually increases. The other axial end of the drive sleeve 135 is connected to the output shaft of the motor 127. The cylindrical portion 139 of one axial end of the second locking tongue 109 is inserted into the drive sleeve 135, and the pin 140 is inserted into the cam groove 142.
[0065] The elastic element 136 can be a compression type helical spring. The elastic element 136 is housed in the drive sleeve 135 and applies force to the second locking tongue 109 in the direction that causes the second locking tongue 109 to extend relative to the drive sleeve 135. That is, the elastic element 136 is housed in the insertion hole 141 of the drive sleeve 135, with one end abutting against the end of the drive sleeve 135 connected to the output shaft of the motor 127, and the other end abutting against the cylindrical portion 139 of the second locking tongue 109, thereby causing the pin-shaped member 140 on the second locking tongue 109 to abut against the cam surface 143 of the cam groove 142.
[0066] As described above, the shape of the connecting hole 134 is non-circular. Specifically, as long as the connecting hole 134 can restrict the rotation of the second latch 109, its shape is not particularly limited. For example, it can be a square shape, an elliptical shape, a tangent circle shape, or various other shapes. Correspondingly, the other end of the second latch 109 in the axial direction also has a corresponding shape. For example, the other end of the second latch 109 in the axial direction has a columnar portion 145 with a square cross-section.
[0067] Continue to refer to Figure 7 The main body 130 of the second lock part 103 can be assembled, for example, in the following manner. It should be noted that the installation sequence is only an example, and various installation sequences can be changed as long as they do not contradict each other.
[0068] First, insert the elastic element 136 into the insertion hole 141 of the drive sleeve 135.
[0069] Next, the cylindrical portion 139 of the second locking tongue 109 is inserted into the insertion hole 141 of the drive sleeve 135 while compressing the elastic member 136, and the pin hole of the cylindrical portion 139 of the second locking tongue 109 is exposed in the cam groove 142 of the drive sleeve 135.
[0070] Then, the pin 140 is inserted into the pin hole. At this time, due to the rebound force of the elastic member 136, the pin 140 abuts against the cam surface 143 of the cam groove 142. Furthermore, when the second latch 109 is pressed from one end of the columnar portion 145, the second latch 109 will retract relative to the drive sleeve 135.
[0071] Next, the drive sleeve 135 is inserted into the mounting chamber 133 from the open end of the second housing 132, aligning the columnar portion 145 of the second latch 109 with the communicating hole 134 of the mounting chamber 133, so that the columnar portion 145 of the second latch 109 passes through the communicating hole 134 of the mounting chamber 133.
[0072] Then, the motor 127 is placed into the mounting chamber 133, and the output shaft of the motor 127 (e.g., a shaft with a cross-shaped cross section) is connected to the other end of the drive sleeve 135 in the axial direction (e.g., a cross-shaped connection hole is formed at the other end of the drive sleeve 135 in the axial direction).
[0073] Finally, the second outer casing 132 is closed by the cover plate 137. Thus, the installation of the main body 130 of the second lock part 103 is completed.
[0074] After the main body 130 is installed, when a command to operate the motor 127 is input through the unlocking panel 129 of the unlocking unit 128, the motor 127 rotates, thereby driving the drive sleeve 135 to rotate. Furthermore, through the cam structure 138 provided between the drive sleeve 135 and the second latch 109, and the structure (non-circular cross-section structure) in which the second latch 109 and the connecting hole 134 cooperate, the rotational motion of the drive sleeve 135 is converted into the linear motion of the second latch 109. Additionally, it should be noted that, for ease of subsequent installation, the initial state of the second latch 109 can be such that it extends relative to the second outer casing 132.
[0075] Furthermore, the main body 130 of the second lock part 103 can be installed into the mounting base 101, for example, in the following manner.
[0076] First, rotate the knob 114 of the first locking part 102 as a whole, so that the first locking part 102 is rotated to a position where the slot 116 formed in the rotating part 106 of the first housing 146 and the main body 130 of the mounting base 101 that houses the second locking part 103 are opposite each other (e.g.) Figure 3 (Position). At this time, the first protrusion 124 formed by the flange portion 123 of the connecting shaft 120 of the first lock portion 102 abuts against the second protrusion 125 formed by the mounting base 101.
[0077] Next, the second locking tongue 109 of the main body 130 of the second locking part 103 is inserted into the slot 116 of the first locking part 102, and then the main body 130 is locked by screws.
[0078] Thus, the installation of the main body 130 of the second lock part 103 is completed.
[0079] In a specific example, refer to Figure 3 In this installed state, the first latch 105 of the first locking part 102 extends to the right, that is, the position where the first latch 105 extends to the right is the locked position 300. Furthermore, in this installed state, the first protrusion 124 of the first locking part 102 abuts against the second protrusion 125 on the right side of the mounting base 101. In addition, since the second latch 109 is inserted into the slot 116, the first locking part 102 is thus fixed entirely within the mounting base 101.
[0080] Reference Figure 8 When a key is inserted into the keyhole 115 of the first lock part 102 and the lock cylinder 104 is driven, the first bolt 105 of the first lock part 102 rotates counterclockwise relative to the first outer shell 146, so that the first bolt 105 is in the upward extension position, that is, the position where the first bolt 105 extends upward is the unlock position 400 (i.e. the first unlocking method).
[0081] Additionally, when the key to the first locking part 102 is not used, and it is necessary to switch the first locking bolt 105 from the locked position 300 to the unlocked position 400, firstly, a password is entered through the unlocking part 128 to activate the motor 127 of the second locking part 103. At this time, the motor 127 rotates, and through the cam structure 138 between the second locking bolt 109 and the drive sleeve 135, the second locking bolt 109 retracts and disengages from the slot 116 (see reference). Figure 4 ).
[0082] Continue to refer to Figure 4 After the second latch 109 disengages from the slot 116, the counterclockwise rotation of the first lock part 102 relative to the mounting base 101 is released (because the first protrusion 124 abuts against the second protrusion 125, the first lock part 102 cannot rotate clockwise). When the knob part 114 of the first housing 146 of the first lock part 102 is rotated counterclockwise (refer to...), Figure 4 (The rotating arrow in the image) The first outer shell 146 drives the first locking part 102 to rotate counterclockwise around the mounting hole 112 of the mounting base 101. At the same time, the first locking tongue 105 of the first locking part 102 rotates together with the first outer shell 146, thereby switching to the unlock position 400 (i.e., the second unlocking method).
[0083] In addition, in the second unlocking method, after the first locking part 102 rotates counterclockwise, the motor 127 can be operated appropriately to make the second locking tongue 109 extend slightly relative to the second housing 132 and abut against the rotating part 106 of the first housing 146. When the motor 127 continues to drive, the rotating part 106 of the first housing 146 presses the second locking tongue 109 in the direction that causes the second locking tongue 109 to retract, causing the pin 140 mounted on the second locking tongue 109 and the cam surface 143 of the cam groove 142 of the drive sleeve 135 to disengage.
[0084] When the first housing 146 rotates to a position where the limiting groove 118 formed in the rotating part 106 is opposite to the second locking tongue 109, since the rotating part 106 no longer presses against the second locking tongue 109, under the force of the elastic member 136, the second locking tongue 109 is driven towards the cam surface 143 of the cam groove 142. At this time, the second locking tongue 109 extends into the limiting groove 118, thereby temporarily restricting the first locking part 102 and keeping the first locking part 102 in the unlocked position 400. In addition, when the second locking tongue 109 extends into the limiting groove 118, it will impact the limiting groove 118, thereby creating a tactile sensation similar to a "click".
[0085] In the second unlocking method, when it is necessary to switch the first locking part 102 to the locked position 300, for example, the knob part 114 can be directly rotated clockwise. Since the depth of the limiting groove 118 is shallow and a guide surface 119 is formed, the first housing 146 can directly push the second locking tongue 109 to retract, thereby allowing the first locking part 102 to rotate to the position where the slot 116 and the second locking tongue 109 are opposite (i.e., the locked position 300). At this time, due to the force of the elastic element 136, the second locking tongue 109 is pushed out by the elastic element 136 and inserted into the slot 116, thus locking the entire first locking part 102. It should be noted that in this method, when it is necessary to switch the first locking part 102 to the locked position 300, the second locking tongue 109 can also be retracted by the motor 127.
[0086] In the double-opening rotary lock 100 of the embodiment, by rotatably mounting the first locking part 102, which is a mechanical lock, into the mounting base 101, and locking or unlocking the first locking part 102 as a whole by the second locking part 103, other unlocking methods can be provided on the basis of the original mechanical lock, which can facilitate other authorized users to unlock the lock.
[0087] In the double-opening rotary lock 100 of the embodiment, by using the connecting shaft 120 to connect the lock cylinder 104 and the first lock tongue 105, the existing mechanical lock can be appropriately modified. While retaining the original mechanical lock of the first lock part 102, the double-opening rotary lock 100 as a whole can be configured and installed more easily according to the different types of storage tools 200.
[0088] Furthermore, by forming a knob portion 114 in the first locking portion 102, when it is necessary to rotate the first locking portion 102 as a whole relative to the mounting base 101, the first locking portion 102 can be easily rotated by operating the knob portion 114.
[0089] In the double-opening rotary latch 100 of the embodiment, a slot 116 is formed in the rotating portion 106 of the first outer shell 146 of the first lock portion 102 as a locking portion 107, allowing the first lock portion 102 to be directly modified from an existing mechanical lock. For example, this slot 116 can be formed by directly machining the rotating portion 106 of the outer shell of an existing mechanical lock. This reduces costs.
[0090] Furthermore, by having the second locking tongue 109 extend and insert into the slot 116 while the first locking part 102 is in the locked position 300, the first locking part 102 can be easily and reliably restricted circumferentially, thereby reliably holding the first locking part 102 in the locked position 300.
[0091] In the double-opening rotary lock 100 of the embodiment, by forming a limiting groove 118 as a limiting part 117 in the rotating part 106 of the first outer shell 146 of the first lock part 102, the first lock part 102 can be reliably and accurately held in the unlocked position 400, and the "click" tactile sensation is formed by the cooperation of the limiting groove 118 and the second lock tongue 109, which makes it easy for the user to find the unlocked position 400.
[0092] In the double-opening rotary lock 100 of the embodiment, by using a motor 127 as the driving member 108 of the second lock part 103, and the unlocking part 128 of the second lock part 103 includes at least one of a feature recognition part, a password recognition part, an NFC recognition part, and a Bluetooth recognition part, the lock on the first lock part 102 as a whole can be unlocked in a different unlocking method than the first lock part 102, thereby expanding the unlocking methods of the double-opening rotary lock 100.
[0093] In particular, by using a button for digital password input and / or a glass piece for fingerprint input on the unlocking panel 129, the double-opening rotary lock 100 can be made more compact and less expensive overall, making it particularly suitable for applications such as filing cabinets or desks (office desks) used in office spaces.
[0094] In the double-opening rotary latch 100 of the embodiment, the second latch 109 and the motor 127 are connected by using a drive sleeve 135 that forms a cam structure 138 between the second latch 109 and the motor 127, and the columnar portion 145 of the second latch 109 passes through a non-circular connecting hole 134. This allows the rotational motion of the motor 127 to be converted into the linear motion of the second latch 109 in a simple, compact and low-cost manner.
[0095] Additionally, it should be noted that although the above embodiments illustrate an example of the mounting base 101 having a first mounting housing 110 and a second mounting housing 111, it is not limited to this. For example, the mounting base 101 may also consist of only a plate-like component, through which the double-opening rotary lock 100 is mounted to the door 201 of the storage tool 200.
[0096] Furthermore, although an example has been described in which the motor 127 of the second locking part 103 and the second locking tongue 109 are housed in the second housing 132, this is not a limitation. The motor 127 and the second locking tongue 109 can actually be directly mounted on the mounting base 101 and connected by, for example, a known lead screw drive mechanism, thereby converting the rotational motion of the motor 127 into the linear motion of the second locking tongue 109.
[0097] Furthermore, although the above describes an example of the second locking tongue 109 extending or retracting in a straight line, it is not limited to this. For example, the second locking tongue 109 can also be directly mounted on the output shaft of the motor 127 and extended or retracted oscillatingly by the drive of the motor 127.
[0098] In the above embodiment, although an example of a cylindrical rotating part 106 has been described, the term "cylindrical" should be understood broadly. That is, as long as the rotating part 106 can rotate freely around the mounting hole 112, various machining processes can be performed on its cylindrical outer peripheral surface. For example, the slot 116 can be machined as described above, or a flat position can be machined. Alternatively, a protrusion can be directly formed on the rotating part 106 as a locking part 107, as long as a corresponding clearance structure is provided in the mounting hole 112.
[0099] In the above embodiment, although an example of the locking part 107 being formed in the rotating part 106 has been described, it is not limited to this. The locking part 107 may also be formed in the knob part 114. Furthermore, as long as the first outer shell 146 can be locked, the locking part 107 is not limited to a groove shape. For example, it may be a protrusion shape, or it may be formed by flattening the cylindrical outer peripheral surface of the rotating part 106.
[0100] In the above embodiment, although an example of the first latch 105 being connected to the lock cylinder 104 via the connecting shaft 120 has been described, it is not limited to this. The first latch 105 is not particularly restricted as long as it can be connected to the lock cylinder 104. For example, the length of the lock cylinder 104 can be made to slightly protrude from the first housing 146, and the first latch 105 can be directly connected to the lock cylinder 104. Alternatively, the first latch 105 may originally have a protrusion extending in the thickness direction, through which the first latch 105 can be directly inserted into the receiving cavity 113 of the first housing 146 and connected to the lock cylinder 104.
[0101] In the above embodiment, although an example of the main body 130 of the second locking part 103 including the elastic member 136 has been described, it is not limited to this, and the second locking part 103 may also not have the elastic member 136. For example, the cam groove 142 of the drive sleeve 135 may also be a cam groove 142 with the same width everywhere. In this way, the cam groove 142 of the drive sleeve 135 and the pin 140 of the second locking tongue 109 are directly connected without buffering.
[0102] Continue to refer to Figure 7 as well as Figure 8 The double-opening rotary lock 100 of this embodiment can be installed in the storage tool 200. Since the double-opening rotary lock 100 provides other unlocking methods on the basis of the original mechanical lock, it can be convenient for other authorized users to unlock.
[0103] As a filing cabinet, typically, the filing cabinet has a cabinet body 202 and a door 201 that can be opened relative to the cabinet body 202. In the embodiment, a double-opening rotary lock 100 is installed on the door 201. When in the locked position 300, the first latch 105 of the double-opening rotary lock 100 swings to one side of the cabinet body 202, thereby restricting the door 201 from opening outward. When in the unlocked position 400, the first latch 105 of the double-opening rotary lock 100 swings to one side of the door 201, thereby allowing the door 201 to open outward. As a table, typically, it has a table body and a drawer that can be pulled out from the table body. In the embodiment, a double-opening rotary lock 100 is installed on the drawer. When in the locked position 300, the first latch 105 of the double-opening rotary lock 100 can swing to one side of the table body (for example, a locking block can be installed on one side of the table body), thereby restricting the drawer from opening outward. When in the unlocked position 400, the first latch 105 of the double-opening rotary lock 100 swings to one side of the drawer, thereby allowing the drawer to open outward.
[0104] Although embodiments of this implementation have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this implementation, the scope of which is defined by the claims and their equivalents.
