Description

Technical Field

[0001] This application relates to the field of instrument and equipment technology, and in particular to a lock and an instrument. Background Technology

[0002] Before conducting experiments using laboratory equipment, reagents should be placed in the reagent compartment. Once the equipment is started, the compartment door should generally not be opened to prevent contamination of the reagents and ensure accurate results. Therefore, the equipment is typically equipped with a lock to secure the compartment door and prevent accidental opening during the experiment.

[0003] In related technologies, locks are equipped with telescopic components that extend and retract to unlock and lock the lock. However, these components are prone to jamming during movement, preventing them from reaching the corresponding unlocking or locking positions. This results in the lock being unable to unlock and lock effectively, making it inconvenient to use. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this application will not be described separately.

[0031] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the directions in normal use, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions in normal use.

[0032] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0033] In related technologies, locks include a transmission component and a telescopic component. The transmission component is capable of moving along a first direction and has a protrusion. The telescopic component has an inclined groove, with the protrusion located within the inclined groove. When the transmission component moves along the first direction, the protrusion exerts a force on the groove wall, pushing the telescopic component to extend and retract. The protrusion is located on one side of the transmission component, and the inclined groove is located on one side of the telescopic component. The force exerted by the protrusion acts on one side of the telescopic component, resulting in uneven force distribution on the telescopic component. This can easily cause jamming during the telescopic movement of the telescopic component, leading to inconvenience in using the lock.

[0034] This application provides an instrument, including a main body and a lock, the lock being disposed on the main body, and the telescopic member 3 being able to abut or separate from the main body.

[0035] It should be noted that the telescopic component 3 can move and contact or separate from the main body.

[0036] It should be noted that when the telescopic component 3 is in contact with the main body, the instrument is in a locked state; when the telescopic component 3 is separated from the main body, the instrument is in an unlocked state.

[0037] For example, the main body includes a door with a lock hole. When the door is in the closed position, the telescopic member 3 extends into the lock hole so that the telescopic member 3 abuts against the wall of the lock hole, and the instrument is in a locked state, locking the door and preventing it from being opened. When the telescopic member 3 retracts from the lock hole so that the telescopic member 3 separates from the wall of the lock hole, the instrument is in an unlocked state, unlocking the door and allowing it to be opened.

[0038] In this embodiment, the lock is located on the main body, and the telescopic member 3 can abut against or separate from the main body. The locking and unlocking of the instrument is achieved by the telescopic movement of the telescopic member 3.

[0039] This application provides a lock; please refer to the embodiments described herein. Figures 1-5 The lock includes a main seat 1, a transmission component 2, and a telescopic component 3. The main seat 1 includes a mounting bracket 11. The transmission component 2 is disposed on the main seat 1 and is movable relative to the mounting bracket 11 along a first direction R1. The transmission component 2 has a first guide portion 21, and the telescopic component 3 has a second guide portion 31. The first guide portion 21 has an intercommunicating clearance groove 212 and a sliding groove 211. The second guide portion 31 has a support portion 312 and protrusions 311 located on opposite sides of the support portion 312; or, the second guide portion 31... The first guide portion 21 has a support portion 312 and protrusions 311 located on opposite sides of the support portion 312, and has a clearance groove 212 and a slide groove 211 on opposite sides of the clearance groove 212. The support portion 312 is located in the clearance groove 212, and each slide groove 211 has a protrusion 311. The telescopic member 3 is movably mounted on the mounting frame 11. The slide groove 211 is used to guide the telescopic member 3 to telescopically move when the transmission member 2 moves along the first direction R1.

[0040] For example, the clearance groove 212 is provided with sliding grooves 211 on both sides of the second direction R2, and the protrusions 311 are located on both sides of the support portion 312 along the second direction R2.

[0041] For example, the telescopic member 3 is movably mounted on the mounting bracket 11 along the third direction R3.

[0042] For example, please refer to Figure 2The slide groove 211 is used to guide the telescopic member 3 to telescopically move along a third direction R3 when the transmission member 2 moves along the first direction R1. The inner surfaces of opposite sides of the slide groove 211 along the third direction R3 are guide surfaces 213. When the transmission member 2 moves along the first direction R1, the guide surfaces 213 guide the telescopic member 3 to telescopically move along the third direction R3. Projected along the second direction R2, the extension direction of the orthographic projection area of ​​the guide surface 213 is arranged to intersect the first direction R1 and the third direction R3 respectively. The projection areas of the guide surfaces 213 on both sides are arranged at intervals. The extension direction of the orthographic projection area of ​​the guide surface 213 is the length direction of the orthographic projection area of ​​the guide surface 213, and it is also the movement direction of the protrusion 311 in the slide groove 211.

[0043] For example, the protrusion 311 abuts against the guide surfaces 213 on opposite sides.

[0044] For example, the telescopic member 3 is movably mounted on the mounting frame 11 along a third direction R3, meaning that the telescopic member 3 moves on the mounting frame 11 along a third direction R3, the mounting frame 11 restricts the telescopic member 3 from moving along a second direction R2, and the mounting frame 11 restricts the telescopic member 3 from moving along a first direction R1.

[0045] For example, the third direction R3 is arranged to intersect with the first direction R1 and the second direction R2 respectively. The first direction R1 and the second direction R2 are arranged to intersect, so that the first direction R1 and the second direction R2 are coplanar and intersect, the first direction R1 and the third direction R3 are coplanar and intersect, the second direction R2 and the second direction R2 are coplanar and intersect, and the first direction R1, the third direction R3 and the second direction R2 are not on the same plane.

[0046] For example, the third direction R3 is perpendicular to the first direction R1.

[0047] For example, the second direction R2 is perpendicular to the first direction R1.

[0048] For example, the third direction R3 is perpendicular to the second direction R2.

[0049] For example, the telescopic member 3 passes through the mounting bracket 11 along the third direction R3.

[0050] For example, the mounting bracket 11 is mounted on the main body.

[0051] In this embodiment, the first guide portion 21 has a clearance groove 212 and a sliding groove 211 that are interconnected, and the second guide portion 31 has a support portion 312 and protrusions 311 located on opposite sides of the support portion 312; or, the second guide portion 31 has a clearance groove 212 and a sliding groove 211 that are interconnected, and the first guide portion 21 has a support portion 312 and protrusions 311 located on opposite sides of the support portion 312; the protrusions 311 are located in the sliding groove 211. When the transmission member 2 moves along the first direction R1, the force between the sliding groove 211 and the protrusions 311 causes the telescopic member 3 to extend and retract, which can drive the telescopic member 3 to extend and retract in a relatively simple and convenient way through the transmission member 2. The clearance groove 212 has sliding grooves 211 on both sides, and the support part 312 is located in the clearance groove 212. Each sliding groove 211 has a protrusion 311. The force provided by the transmission component 2 to move the telescopic component 3 is distributed on both sides of the telescopic component 3, so the telescopic component 3 is subjected to more even force, reducing the possibility of jamming during the telescopic movement of the telescopic component 3, and making the lock easier to use. The transmission component 2 and the telescopic component 3 are integrated on the main seat 1, and the transmission component 2 and the telescopic component 3 do not need to be connected to the main body, which facilitates the disassembly and assembly of the lock.

[0052] In some embodiments, please refer to Figures 2-5 The clearance groove 212 and the slide groove 211 are formed on the transmission member 2, and the support part 312 and the protrusion 311 are formed on the telescopic member 3.

[0053] For example, when the transmission member 2 moves toward the telescopic member 3 along the first direction R1, the protrusion 311 of the telescopic member 3 moves away from the mounting frame 11 along the third direction R3, so that the telescopic member 3 retracts; when the transmission member 2 moves away from the telescopic member 3 along the first direction R1, the protrusion 311 of the telescopic member 3 moves toward the mounting frame 11 along the third direction R3, so that the telescopic member 3 extends.

[0054] It should be noted that when the transmission component 2 moves away from the telescopic component 3 along the first direction R1, the protrusion 311 can disengage from the slide groove 211.

[0055] In this embodiment, the support 312 moves within the clearance groove 212, which requires sufficient space for the support 312 to move. The protrusion 311 moves within the sliding groove 211, which also requires sufficient space for the protrusion 311 to move. The clearance groove 212 and the sliding groove 211 are formed on the transmission member 2, and the support 312 and the protrusion 311 are formed on the telescopic member 3. This facilitates control of the volume of the telescopic member 3, allowing it to be smaller and making it easier to move.

[0056] It is understood that the clearance groove 212 and the slide groove 211 are not limited to being formed on the transmission member 2, and the support portion 312 and the protrusion 311 are not limited to being formed on the telescopic member 3. Exemplarily, the clearance groove 212 and the slide groove 211 are formed on the telescopic member 3, and the support portion 312 and the protrusion 311 are formed on the transmission member 2.

[0057] In some embodiments, please refer to Figure 4 and Figure 5 The sliding grooves 211 are located on opposite sides of the clearance grooves 212 along the second direction R2. The telescopic member 3 moves telescopically along the third direction R3. The third direction R3 is arranged intersecting with the first direction R1 and the second direction R2. The first direction R1 and the second direction R2 are arranged intersecting. The telescopic member 3 includes a first shaft 32 and a second shaft 33. The first shaft 32 has a mounting hole 321. The second shaft 33 passes through the mounting hole 321 along the second direction R2. A protrusion 311 is formed on the second shaft 33. The first shaft 32 passes through the mounting bracket 11 along the third direction R3.

[0058] It should be noted that the first shaft 32 and the second shaft 33 are manufactured independently and then assembled.

[0059] For example, the second shaft 33 is interference-fitted with the wall of the mounting hole 321.

[0060] For example, the first axis 32 is cylindrical.

[0061] For example, the second axis 33 is cylindrical.

[0062] In this embodiment of the application, the telescopic member 3 includes a first shaft 32 and a second shaft 33. The first shaft 32 has a mounting hole 321, and the second shaft 33 passes through the mounting hole 321 along the second direction R2. A protrusion 311 is formed on the second shaft 33, which facilitates the separate processing of the first shaft 32 and the second shaft 33, and then assembling them into the telescopic member 3. This facilitates the processing and manufacturing of the telescopic member 3 and helps to reduce the manufacturing cost of the lock.

[0063] It is understood that the telescopic member 3 is not limited to including the first shaft 32 and the second shaft 33, and the second shaft 33 is not limited to passing through the mounting hole 321 along the second direction R2. Exemplarily, the telescopic member 3 is a one-piece molded structure.

[0064] In some embodiments, please refer to Figures 1-4 The lock also includes an elastic element 4. One end of the elastic element 4 along the first direction R1 abuts against the transmission element 2, and the other end of the elastic element 4 along the first direction R1 abuts against the main seat 1. The elastic force of the elastic element 4 causes the transmission element 2 to have a tendency to move towards the telescopic element 3 along the first direction R1.

[0065] For example, the elastic element 4 is a spring.

[0066] For example, the elastic element 4 is a compression spring.

[0067] For example, the first direction R1 is parallel to the up and down direction.

[0068] For example, the telescopic member 3 is located below the transmission member 2.

[0069] For example, the elastic element 4 is fitted onto a portion of the structure of the transmission element 2.

[0070] In this embodiment, one end of the elastic member 4 along the first direction R1 abuts against the transmission member 2, and the other end of the elastic member 4 along the first direction R1 abuts against the main seat 1. The elastic force of the elastic member 4 causes the transmission member 2 to tend to move towards the telescopic member 3 along the first direction R1. The elastic force of the elastic member 4 can push the transmission member 2 to move towards the telescopic member 3 along the first direction R1, reducing the possibility of the transmission member 2 getting stuck during the movement towards the telescopic member 3 along the first direction R1. One end of the elastic member 4 abuts against the transmission member 2 along the first direction R1. The clearance groove 212 and the sliding groove 211 are formed on the transmission member 2. The clearance groove 212 and the sliding groove 211 require a large space, and the size of the transmission member 2 can be set to be large. The transmission member 2 has enough space to abut against and cooperate with the elastic member 4. The transmission member 2 does not need to be provided with an additional support structure to cooperate with the elastic member 4.

[0071] It is understandable that the lock may not have a spring element 4.

[0072] In some embodiments, please refer to Figures 1-4 The lock also includes a guide member 5, which is disposed on the mounting bracket 11. The guide member 5 has a guide groove 51, and the transmission member 2 is partially located in the guide groove 51 so that the guide groove 51 guides the transmission member 2 to move along the first direction R1.

[0073] For example, the guide member 5 is located between the mounting bracket 11 and the transmission member 2 along the third direction R3, and the telescopic member 3 passes through the guide member 5 and the mounting bracket 11 in sequence along the third direction R3.

[0074] In this embodiment, the guide member 5 has a guide groove 51, and the transmission member 2 is partially located within the guide groove 51 so that the guide groove 51 guides the transmission member 2 to move along the first direction R1. The guide groove 51 guides the transmission member 2 to move along the first direction R1, reducing the possibility of the transmission member 2 deviating during its movement along the first direction R1, improving the accuracy of the transmission member 2's movement, and helping to reduce the possibility of jamming during the telescopic movement of the telescopic member 3. When the telescopic member 3 passes through the guide member 5 and the mounting bracket 11 sequentially along the third direction R3, the guide member 5 restricts the telescopic member 3 from moving along the first direction R1 and along the second direction R2, allowing the telescopic member 3 to move telescopically along the third direction R3.

[0075] It is understood that the lock is not limited to the installation of guide member 5. Exemplarily, the mounting bracket 11 has a guide hole through which the transmission member 2 passes along a first direction R1, and the guide hole guides the transmission member 2 to move along the first direction R1.

[0076] It is understandable that the lock may not have guide member 5 and guide groove 51.

[0077] In some embodiments, please refer to Figures 1-4 The main seat 1 also includes a drive device 12, which is mounted on the mounting frame 11. The transmission component 2 is disposed on the drive device 12, and the drive device 12 is used to drive the transmission component 2 to move along the first direction R1.

[0078] In this embodiment, the drive device 12 is mounted on the mounting bracket 11, and the transmission component 2 is disposed on the drive device 12. The drive device 12 is used to drive the transmission component 2 to move along the first direction R1. By automatically driving the transmission component 2 to move along the first direction R1 through the drive device 12, the telescopic component 3 is moved to extend and retract. There is no need to manually operate the transmission component 2, which improves the intelligence of the lock.

[0079] It is understood that the main seat 1 may not be equipped with a drive unit 12. Exemplarily, the transmission component 2 is manually pushed or pulled by the user.

[0080] In some embodiments, please refer to Figure 4 The driving device 12 is an electromagnet driving device 12, which has an output shaft 121. The transmission member 2 is connected to the output shaft 121. The output shaft 121 extends and retracts along the first direction R1 to drive the transmission member 2 to move along the first direction R1.

[0081] The electromagnet drive device 12 is a drive device that uses the magnetic effect of electric current to generate magnetism in an iron core, thereby attracting ferromagnetic materials to perform work. The electromagnet drive device 12 has a coil and an iron core. The iron core is inserted inside the coil. When the coil is energized, it generates a magnetic field, and the iron core is magnetized by the magnetic field of the coil, driving the output shaft 121 to move by magnetic force.

[0082] It should be noted that the electromagnet drive device 12 is electrically connected to the main body.

[0083] For example, when the transmission member 2 moves toward the telescopic member 3 along the first direction R1, the end of the transmission member 2 connected to the output shaft 121 moves toward the telescopic member 3 along the first direction R1; when the transmission member 2 moves away from the telescopic member 3 along the first direction R1, the end of the transmission member 2 connected to the output shaft 121 moves away from the telescopic member 3 along the first direction R1.

[0084] For example, the electromagnet drive device 12 has a housing connected to the mounting bracket 11, and an output shaft 121 disposed in the housing, the output shaft 121 being movable relative to the housing along a first direction R1.

[0085] For example, the elastic element 4 is sleeved on the output shaft 121, one end of the elastic element 4 abuts against the transmission element 2 along the first direction R1, and the other end of the elastic element 4 abuts against the housing along the first direction R1.

[0086] For example, one end of the elastic member 4 abuts against the transmission member 2 along the first direction R1, and the other end of the elastic member 4 abuts against the mounting bracket 11 along the first direction R1.

[0087] For example, when the electromagnet drive device 12 is energized, the output shaft 121 retracts into the housing along the first direction R1, driving the transmission member 2 to move away from the telescopic member 3 along the first direction R1; when the electromagnet drive device 12 is de-energized, the transmission member 2 moves towards the telescopic member 3 along the first direction R1 under the action of gravity.

[0088] For example, the housing is threaded to the mounting bracket 11.

[0089] For example, the transmission component 2 is connected to the output shaft 121 via a pin.

[0090] In this embodiment, the driving device 12 is an electromagnet driving device 12. The electromagnet driving device 12 has an output shaft 121. The transmission member 2 is connected to the output shaft 121. The output shaft 121 extends and retracts along the first direction R1 to drive the transmission member 2 to move along the first direction R1. The electromagnet driving device 12 has a relatively simple structure and is easy to use.

[0091] It is understood that the drive device 12 is not limited to an electromagnet drive device 12. For example, the drive device 12 is a motor.

[0092] In some embodiments, please refer to Figures 1-4 The lock also includes a detection device 6, which is mounted on the mounting bracket 11. The detection device 6 is used to send a detection signal so that the drive device 12 drives the transmission member 2 to move along the first direction R1.

[0093] For example, the optocoupler detection device 6 is electrically connected to the main body.

[0094] In this embodiment, the detection device 6 is installed on the mounting bracket 11. The detection device 6 is used to send a detection signal so that the drive device 12 drives the transmission component 2 to move along the first direction R1. The detection device 6 automatically detects and controls the transmission component 2 to move along the first direction R1, thereby driving the telescopic component 3 to move in and out, automatically controlling the locking and unlocking of the lock, and improving the level of intelligence.

[0095] It is understood that the lock is not limited to including the detection device 6. Exemplarily, the lock has a drive switch that controls the drive device 12 to drive the transmission member 2 to move along the first direction R1.

[0096] In some embodiments, please refer to Figure 3 and Figure 4 The detection device 6 is an optical coupler detection device 6, and the mounting bracket 11 has a detection through hole 111. The optical coupler detection device 6 is located on one side of the detection through hole 111.

[0097] For example, when the door is in the closed position, the door is located on the side of the detection through-hole 111 away from the optocoupler detection device 6.

[0098] In this embodiment, the detection device 6 is an optical coupler detection device 6. The mounting bracket 11 has a detection through hole 111. The optical coupler detection device 6 is disposed on one side of the detection through hole 111. The optical coupler detection device 6 detects whether there is an object on one side of the detection through hole 111, thereby controlling the drive device 12. The detection is relatively convenient.

[0099] It is understood that the detection device 6 is not limited to an optical coupler detection device 6. Exemplarily, the detection device 6 is an infrared detector or sensor.

[0100] In some embodiments, please refer to Figure 3 and Figure 4 The mounting bracket 11 has a bottom hole 112, which is located on the side of the guide member 5 away from the drive device 12 along the first direction R1. The bottom hole 112 is connected to the guide groove 51. The transmission member 2 moves toward the telescopic member 3 along the first direction R1 so that the transmission member 2 extends into the bottom hole 112.

[0101] In this embodiment, the bottom hole 112 is located on the side of the guide member 5 away from the drive device 12 along the first direction R1. The bottom hole 112 is connected to the guide groove 51. The transmission member 2 moves towards the telescopic member 3 along the first direction R1 so that the transmission member 2 extends into the bottom hole 112. The transmission member 2 can extend into the bottom hole 112. The space along the first direction R1 of the mounting member provides the transmission member 2 with the space along the first direction R1, which is beneficial to reduce the size of the lock along the first direction R1 and facilitates the installation of the lock in the case of limited space.

[0102] In some embodiments, please refer to Figure 1 When there is no object on one side of the detection hole 111, the optocoupler detection device 6 does not send a detection signal, the electromagnet drive device 12 is not powered, and the transmission component 2 moves along the first direction R1 toward the telescopic component 3 to the maximum range under the action of gravity and the elastic force of the elastic component 4, so that the telescopic component 3 is in the retracted state, the telescopic component 3 can be separated from the main body, and the instrument is in the unlocked state.

[0103] In some embodiments, please refer to Figure 2When an object is detected on one side of the through hole 111, the optocoupler detection device 6 sends a detection signal, the electromagnet drive device 12 is energized, and the output shaft 121 of the electromagnet drive device 12 drives the transmission component 2 to move away from the telescopic component 3 along the first direction R1. The protrusion 311 moves towards the mounting bracket 11 along the third direction R3 under the guidance of the slide groove 211, so that the telescopic component 3 is in the extended state and can abut against the main body, so that the instrument is in the locked state.

[0104] For example, when the door is in the closed position, the door is located on the side of the detection through hole 111 away from the optical coupler detection device 6, and the optical coupler detection device 6 detects the door and sends a detection signal; when the door is in the open position, the door is not located on the side away from the optical coupler detection device 6, there is no object on the side of the detection through hole 111 away from the optical coupler detection device 6, and the optical coupler detection device 6 does not send a detection signal.

[0105] In some embodiments, the main body includes a controller, which is electrically connected to the detection device 6 and the drive device 12.

[0106] For example, when the controller receives the detection signal from the optocoupler detection device 6, the controller controls the electromagnet drive device 12 to be powered on; when the controller does not receive the detection signal from the optocoupler detection device 6, the controller controls the electromagnet drive device 12 to be powered off.

[0107] In some embodiments, when the instrument is in a locked state, the electromagnet drive device 12 can be de-energized by the program, causing the transmission member 2 to move away from the telescopic member 3 along the first direction R1, driving the protrusion 311 to move away from the mounting bracket 11 along the third direction R3, causing the telescopic member 3 to retract, and the instrument to switch from the locked state to the unlocked state.
