Description

Technical Field

[0001] The utility model relates to the technical field of locks, and particularly provides a lock and a household appliance including the lock. Background Art

[0002] The technical background of the sliding groove lock can be traced back to the mid-19th century. At that time, the demand for locks for sliding doors and drawers gradually increased, which promoted the invention and application of the sliding groove lock.

[0003] The initial sliding groove lock was made of wood and metal materials. Its lock core consisted of multiple metal pins and springs, and the key was also a relatively simple metal product. With the development of technology, the materials and structures of the sliding groove lock have been continuously improved and optimized, forming the modern sliding groove lock. Modern sliding groove locks usually adopt lightweight materials such as metal or plastic in terms of materials to reduce weight and cost. In terms of structure, modern sliding groove locks adopt a more complex lock core structure and pin shape to improve safety and reliability.

[0004] During the use of the existing sliding groove lock, due to the lack of seismic resistance function, obvious vibrations occur when the sliding groove lock is locked, resulting in relatively large noise and affecting the user experience. Content of the Utility Model

[0005] The utility model aims to solve the above technical problems, that is, to at least to a certain extent solve the problem that the existing lock generates relatively large vibrations during use due to the lack of seismic resistance function, thereby affecting the user experience.

[0006] In a first aspect, the utility model provides a lock for locking a first component and a second component. The lock includes a lock assembly, a transmission assembly, and a locking member. The lock assembly includes a lock body, a lock core, and an elastic member. The lock body is installed on the first component. The first end of the transmission assembly is connected to the lock assembly, and the second end of the transmission assembly is connected to the locking member. The lock core can rotate relative to the lock body to drive the transmission assembly to move so as to lock the locking member on the second component. The elastic member is arranged between the lock core and the lock body and is used to reduce the vibration between the lock body and the lock core.

[0007] In a preferred technical solution of the above lock, the lock assembly further includes a driving member. One end of the driving member is connected to the lock core, and the other end of the driving member is connected to the first end of the transmission assembly. When the lock core rotates relative to the lock body, the driving member can drive the transmission assembly to move to lock the locking member on the second component.

[0008] In the preferred technical solution of the above-mentioned lock, the transmission assembly includes a connecting rod groove and a connecting rod member. One end of the connecting rod member is connected to the locking member, and the other end of the connecting rod member is connected to the connecting rod groove. The driving member includes a rotating rod, a driving rod connected to the rotating rod, and a protrusion provided on the driving rod. The rotating rod is connected to the lock core, and the protrusion is located in the connecting rod groove and can drive the connecting rod groove to move in a direction close to or away from the second component.

[0009] In the preferred technical solution of the above-mentioned lock, the lock core has a receiving cavity. The elastic member is located in the receiving cavity, one end of the elastic member is connected to the lock core, and the other end of the elastic member is connected to the rotating rod. A sliding groove is provided on the lock core. The sliding groove has a first position and a second position. A sliding pin adapted to the sliding groove is provided on the lock body. When the lock core rotates relative to the lock body, the sliding pin can slide along the sliding groove so that the sliding pin can switch between the first position and the second position. When the sliding pin is in the first position, the rotating rod can drive the connecting rod groove to move in a direction close to the second component; when the sliding pin is in the second position, the rotating rod can drive the connecting rod groove to move in a direction away from the second component.

[0010] In the preferred technical solution of the above-mentioned lock, the locking member includes a first locking pin and a second locking pin. The connecting rod member includes a connecting rod and a steering member. The connecting rod is fixed on the connecting rod groove, and one end of the connecting rod is connected to the first locking pin through the steering member, and the other end of the connecting rod is connected to the second locking pin. Both the first locking pin and the second locking pin can be locked on the second component.

[0011] In the preferred technical solution of the above-mentioned lock, the lock assembly further includes a connecting member provided on the lock body. The connecting member is used to mount the lock body on the first component.

[0012] In the preferred technical solution of the above-mentioned lock, the lock assembly further includes a lock tongue. The lock tongue is provided at the bottom of the lock core and is fixedly connected to the lock core. The lock core can drive the lock tongue to rotate to abut the lock tongue against the second component.

[0013] In the preferred technical solution of the above-mentioned lock, the lock assembly further includes a screw. The lock tongue is detachably connected to the bottom of the lock core through the screw.

[0014] In the preferred technical solution of the above-mentioned lock, the lock further includes a locking seat adapted to the locking member. The locking seat is installed on the second component, and the lock assembly can drive the transmission component to move so as to lock the locking member on the locking seat.

[0015] In a second aspect, the present utility model further provides a household appliance, which includes a first component, a second component, and the lock described above.

[0016] In the case of adopting the above-mentioned preferred technical solution, by setting the lock to include a lock assembly, a transmission component, and a locking member, the lock assembly can be driven to move the transmission component, and then the transmission component drives the locking member to move to achieve locking. Thereby, the vibration generated by the locking member during the locking process can be reduced, the impact generated during the locking process can be reduced, and the noise generated when the lock is locked can be reduced. At the same time, by setting the lock assembly to include a lock body, a lock core, and an elastic member, the vibration between the lock body and the lock core can be reduced by the elastic member, greatly improving the user experience.

[0017] Furthermore, by setting the transmission component as a connecting rod groove and a connecting rod member, the protrusion can always be located in the connecting rod groove. When the lock core drives the driving rod to rotate, the protrusion can drive the connecting rod groove to move towards the second component, thereby locking the locking member on the second component. When the lock core drives the driving rod to rotate in the opposite direction, the protrusion can drive the connecting rod groove to move away from the second component, thereby unlocking the locking member from the second component.

[0018] Furthermore, by arranging the elastic member in the accommodating cavity, not only can the vibration between the lock core and the lock body be reduced, but also when the lock core rotates relative to the lock body, the lock core can be allowed to move along the axial direction of the lock body, thereby facilitating the switching of the sliding pin between the first position and the second position, and further facilitating the movement of the connecting rod groove towards or away from the second component, that is, facilitating the locking and unlocking of the locking member on the second component.

[0019] Still further, compared with the form of setting the locking member as only one locking pin, setting the locking member to include a first locking pin and a second locking pin can lock the first locking pin on the second component through a connecting rod and a steering member, and lock the second locking pin on the second component through a connecting rod, thereby making the locking of the lock more stable.

[0020] Still further, by providing a connecting member, it is convenient to install the lock assembly on the first component.

[0021] Furthermore, by providing a locking tongue, in the case where the locking member is locked to the second component, the locking tongue can abut against the second component and cooperate with the first locking pin and the second locking pin to achieve three-point locking, thereby making the locking of the lock more secure. At the same time, it can further reduce the vibration of the lock during locking, reduce the noise of the lock, and further improve the user experience.

[0022] Furthermore, compared with the form of setting a locking groove on the second component to lock the locking member to the second component, the form of setting a locking seat adapted to the locking member on the second component to lock the locking member to the second component can reduce the assembly difficulty of the lock and further improve the user experience.

[0023] In addition, the household appliance further provided by the present utility model on the basis of the above technical solution includes the lock described above, and thus has the beneficial effects of the above lock. Compared with the household appliance before improvement, the household appliance of the present utility model has less vibration and less noise during unlocking and locking, and the user experience is also better.

For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0036] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the lock of the present utility model.

[0037] As Figure 1 shown, the lock of the present utility model is used to lock a first component and a second component. Specifically, the lock includes a lock assembly 1, a transmission assembly, and a locking member. The lock assembly 1 includes a lock body 11, a lock core 12, and an elastic member 16. The lock body 11 is installed on the first component. The first end of the transmission assembly is connected to the lock core 12, and the second end of the transmission assembly is connected to the locking member. The lock core 12 can rotate relative to the lock body 11 to drive the transmission assembly to move so as to lock the locking member on the second component. The elastic member 16 is disposed between the lock core and the lock body and is used to reduce the vibration between the lock body 11 and the lock core 12.

[0038] By setting the lock to include a lock assembly 1, a transmission assembly, and a locking member, the transmission assembly can be driven to move by the lock assembly 1, and then the locking member can be driven to move by the transmission assembly to achieve locking. Thereby, the vibration generated by the locking member during the locking process can be reduced, the impact generated during the locking process can be reduced, and the noise generated when the lock is locked can be reduced. At the same time, by setting the lock assembly 1 to include a lock body 11, a lock core 12, and an elastic member 16, the vibration between the lock body 11 and the lock core 12 can be reduced by the elastic member 16, greatly improving the user experience.

[0039] It should be noted that in practical applications, the first end of the transmission assembly can be directly connected to the lock core 12, or a driving member can be provided below the lock core, and the first end of the transmission assembly is connected to the lock core 12 through the driving member, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present utility model and should all be included in the protection scope of the present utility model.

[0040] Preferably, as Figure 2 shown, the lock assembly 1 of the present utility model further includes a driving member. One end of the driving member is connected to the lock core 12, and the other end of the driving member is connected to the first end of the transmission assembly. When the lock core 12 rotates relative to the lock body 11, the driving member can drive the transmission assembly to move to lock the locking member on the second component.

[0041] It should be noted that in practical applications, those skilled in the art can set the transmission assembly in the form of gear 233 transmission, or can also set the transmission assembly in the form of link transmission, etc. Such adjustments and changes to the specific setting type of the transmission assembly do not deviate from the principle and scope of the present utility model and should all be included in the protection scope of the present utility model.

[0042] Preferably, as Figures 1 to 5 shown, the transmission assembly includes a link slot 21 and a link member. One end of the link member is connected to the locking member, and the other end of the link member is connected to the link slot 21. The driving member includes a rotating rod 133, a driving rod 131 connected to the rotating rod 133, and a protrusion 132 provided on the driving rod 131. The rotating rod 133 is connected to the lock core 12, and the protrusion 132 is located in the link slot 21 and can drive the link slot 21 to move in a direction close to or away from the second component.

[0043] With such a setting, the protrusion 132 can always be located within the connecting rod groove 21. When the lock core 12 drives the driving rod 131 to rotate, the protrusion 132 can drive the connecting rod groove 21 to move, thereby driving the locking member to move in the direction towards the second component, and further locking the locking member on the second component. When the lock core 12 drives the driving rod 131 to rotate in the reverse direction, the protrusion 132 can drive the connecting rod groove 21 to move, thereby driving the locking member to move in the direction away from the second component, so that the locking member is unlocked from the second component.

[0044] It should be noted that the driving member is not limited to being configured as the driving rod 131 and the protrusion 132. For example, the driving member can also be configured as a driving block, etc. Such adjustments and changes to the specific setting type of the driving member do not deviate from the principle and scope of the present utility model and should all be included within the protection scope of the present utility model. Of course, preferably, the driving member is configured as the driving rod 131 and the protrusion 132.

[0045] Preferably, the lock core 12 has a receiving cavity. The elastic member 16 is located within the receiving cavity, one end of the elastic member 16 is connected to the lock core 12, and the other end of the elastic member 16 is connected to the rotating rod 133. A sliding groove 121 is provided on the lock core 12. The sliding groove 121 has a first position 1211 and a second position 1212. A sliding pin 112 adapted to the sliding groove 121 is provided on the lock body 11. When the lock core 12 rotates relative to the lock body 11, the sliding pin 112 can slide along the sliding groove 121 so that the sliding pin 112 can switch between the first position 1211 and the second position 1212.

[0046] Among them, in the case where the sliding pin 112 is in the first position 1211, the rotating rod 133 can drive the connecting rod groove 21 to move in the direction towards the second component;

[0047] In the case where the sliding pin 112 is in the second position 1212, the rotating rod 133 can drive the connecting rod groove 21 to move in the direction away from the second component.

[0048] With such a setting, that is, by arranging the elastic member 16 within the receiving cavity, not only can the vibration between the lock core 12 and the lock body 11 be reduced, but also when the lock core 12 rotates relative to the lock body 11, the lock core 12 can be allowed to move along the axial direction of the lock body 11, thereby facilitating the switching of the sliding pin 112 between the first position 1211 and the second position 1212, and further facilitating the realization of the movement of the connecting rod groove 21 in the direction towards or away from the second component, that is, facilitating the locking and unlocking of the locking member on the second component.

[0049] Specifically, the sliding groove 121 is a U-shaped groove. One end of the U-shaped groove is the first position 1211, and the second end of the U-shaped groove is the second position 1212.

[0050] When the lock core 12 rotates relative to the lock body 11, the lock core 12 can also overcome the elastic force of the elastic member 16 and move relative to the lock body 11 in the axial direction of the lock body 11, so that the sliding pin 112 moves along the chute 121 from the first position 1211 to the second position 1212, and then drives the rotating rod 133 to rotate, that is, drives the connecting rod groove 21 to move towards the direction close to the second component, so as to lock the locking member on the second component.

[0051] When the lock core 12 rotates relative to the lock body 11 in the opposite direction, the lock core 12 can overcome the elastic force of the elastic member 16 and move relative to the lock body 11 in the axial direction of the lock body 11, so that the sliding pin 112 moves along the chute 121 from the second position 1212 to the first position 1211, and then drives the rotating rod 133 to rotate in the opposite direction, that is, drives the connecting rod groove 21 to move towards the direction away from the second component, so as to unlock the locking member from the second component.

[0052] It should be noted that in practical applications, those skilled in the art can set the elastic member 16 as a spring, or can also set the elastic member 16 as a spring sheet, etc. Such adjustments and changes to the specific setting type of the elastic member 16 do not deviate from the principle and scope of the present invention, and should all be included in the protection scope of the present invention.

[0053] Preferably, the elastic member 16 is a spring.

[0054] Preferably, as Figure 1 、 Figure 3 and Figure 4 shown, the locking member includes a first locking pin 31 and a second locking pin 32, the connecting rod member includes a steering member 23 and a connecting rod 22, the connecting rod 22 is fixed on the connecting rod groove 21, one end of the connecting rod 22 is connected to the first locking pin 31 through the steering member 23, the other end of the connecting rod 22 is connected to the second locking pin 32, and both the first locking pin 31 and the second locking pin 32 can be locked on the second component.

[0055] Through such a setting, compared with the form of setting the locking member as only one locking pin, setting the locking member as the form including the first locking pin 31 and the second locking pin 32 can lock the first locking pin 31 on the second component and lock the second locking pin 32 on the second component through the connecting rod 22 and the steering member 23, so that the locking of the lock is more stable.

[0056] It should be noted that the present invention does not make any limitation on the specific setting form of the steering member 23, as long as it can drive the connecting rod 22 to move towards the direction close to the lock assembly 1 when the connecting rod groove 21 moves towards the direction away from the lock assembly 1.

[0057] Specifically, as Figure 5As shown, the steering member 23 includes a housing 231, and a gear 233, a first rack 232, and a second rack 234 disposed within the housing 231. Among them, both the first rack 232 and the second rack 234 are meshed with the gear 233. The first rack 232 is connected to the connecting rod 22, and the second rack 234 is connected to the first locking pin 31. When the connecting rod groove 21 moves in a direction away from the lock assembly 1, the connecting rod 22 drives the first rack 232 to move in a direction away from the lock assembly 1. At the same time, under the action of the gear 233, the second rack 234 drives the first locking pin 31 to move in a direction close to the lock assembly 1 to unlock the first locking pin 31 from the second component.

[0058] Preferably, as Figure 2 shown, the lock assembly 1 further includes a connecting member disposed on the lock body 11, and the connecting member is used to mount the lock body 11 on the first component.

[0059] By setting it in this way, it is convenient to mount the lock assembly 1 on the first component.

[0060] It should be noted that in practical applications, those skilled in the art can set the connecting member as a connecting piece 111, or can also set the connecting member as a connecting rod, etc. Such adjustments and changes to the specific setting type of the connecting member do not deviate from the principle and scope of the present utility model and should all be included in the protection scope of the present utility model.

[0061] Preferably, as Figure 2 shown, the connecting member is a connecting piece 111, and a through hole 1111 is provided on the connecting piece 111.

[0062] When installing the lock body 11, by passing a bolt through the through hole 1111 on the connecting piece 111, the lock body 11 can be fixed on the first component to achieve the convenient installation of the lock body 11.

[0063] It should be noted that in practical applications, those skilled in the art can set the number of the connecting pieces 111 as one, or can also set the number of the connecting pieces 111 as two, or can also set the number of the connecting pieces 111 as multiple, etc. Such adjustments and changes to the specific setting number of the connecting pieces 111 do not deviate from the principle and scope of the present utility model and should all be included in the protection scope of the present utility model.

[0064] Preferably, as Figure 2 shown, the number of the connecting pieces 111 is two, and the two connecting pieces 111 are spaced apart along the axial direction of the lock body 11.

[0065] By setting the number of the connecting pieces 111 as two, the installation of the lock body 11 can be made more stable.

[0066] Preferably, asFigure 2 As shown, the lock assembly 1 of the present utility model further includes a lock tongue 14. The lock tongue 14 is arranged at the bottom of the lock core 12 and is fixedly connected to the lock core 12. The lock core 12 can drive the lock tongue 14 to rotate so as to abut the lock tongue 14 against the second component.

[0067] By providing the lock tongue 14, when the locking member is locked on the second component, the lock tongue 14 can abut against the second component, thereby making the locking of the lock more firm. At the same time, it can further reduce the vibration of the lock during locking, reduce the noise of the lock, and further improve the user experience.

[0068] It should be noted that in actual applications, those skilled in the art can detachably connect the lock tongue 14 to the bottom of the lock core 12 through a screw 15, or the lock tongue 14 can also be welded to the bottom of the lock core 12, etc. Such adjustments and changes to the specific connection method between the lock tongue 14 and the lock core 12 do not deviate from the principle and scope of the present utility model and should be included in the protection scope of the present utility model.

[0069] Preferably, as Figure 2 shown, a threaded rod (not shown in the figure) is provided at the bottom of the lock core of the present utility model. The lock assembly 1 further includes a screw 15 adapted to the threaded rod. The lock tongue 14 is detachably connected to the bottom of the lock core 12 through the screw 15.

[0070] It should be noted that a locking groove can be provided on the second component, and the locking member is directly snapped into the locking groove to lock the locking member on the second component. Or, a locking seat adapted to the locking member can also be provided on the second component. The locking seat is installed on the second component, and the lock assembly 1 can drive the transmission component to move to lock the locking member on the locking seat, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present utility model and should be included in the protection scope of the present utility model.

[0071] Preferably, as Figure 1 、 Figure 2 and Figure 4 shown, the lock of the present utility model further includes a locking seat adapted to the locking member. The locking seat is installed on the second component, and the lock assembly 1 can drive the transmission component to move to lock the locking member on the locking seat.

[0072] With such a setting, compared with the form of setting a locking groove on the second component to lock the locking member on the second component, the form of setting a locking seat adapted to the locking member on the second component to lock the locking member on the second component can reduce the assembly difficulty of the lock and further improve the user experience.

[0073] Specifically, as Figure 1 、Figure 2 and Figure 4 As shown in Figure 4 , the lock includes a first locking seat 33 adapted to the first locking pin 31 and a second locking seat 34 adapted to the second locking pin 32. Among them, both the first locking seat 33 and the second locking seat 34 are arranged on the second component, and the first locking seat 33 and the second locking seat 34 are respectively installed on both sides of the lock assembly 1. The lock assembly 1 can drive the transmission assembly to move so as to lock the first locking pin 31 on the first locking seat 33 and lock the second locking pin 32 on the second locking seat 34.

[0074] It should be noted that in practical applications, the lock can be applied to a door, that is, the first component is the door body and the second component is the door frame. Or, the lock can also be applied to a box body, that is, the first component is a drawer and the second component is the box body, and so on. Such adjustments and changes in the specific application directions of the lock do not deviate from the principles and scope of the present utility model and should all be included in the protection scope of the present utility model.

[0075] Hereinafter, taking the first component as the door body and the second component as the door frame as an example, the specific embodiments of the present utility model will be introduced in detail.

[0076] As Figure 1 shown, the lock body 11 is installed on the door body, and the first locking seat 33 and the second locking seat 34 are respectively installed on the upper door frame and the lower door frame (not shown in the figure). When the user rotates the lock core 12, the lock core 12 drives the driving rod 131 to rotate. The protrusion 132 on the driving rod 131 drives the link slot 21 to move away from the first locking seat 33 in the link slot 21, and further drives the first rack 232 to move towards the lock assembly 1. Under the action of the gear 233, the second rack 234 drives the first locking pin 31 to move towards the first locking seat 33, so as to lock the first locking pin 31 in the first locking seat 33. At the same time, since the link slot 21 moves away from the first locking seat 33, the link 22 is driven to move towards the second locking pin 32, that is, the link 22 drives the second locking pin 32 to move towards the second locking seat 34 and locks the second locking pin 32 in the second locking seat 34. At the same time, the rotation of the lock core 12 drives the lock tongue 14 to rotate and abuts the lock tongue 14 against the door frame, realizing the locking of the door body and the door frame by the lock.

[0077] When the user rotates the lock core 12 in the reverse direction, the lock core 12 drives the drive rod 131 to rotate in the reverse direction. The protrusion 132 on the drive rod 131 is within the connecting rod groove 21 and drives the connecting rod groove 21 to move towards the direction close to the first locking seat 33. Further, it drives the first rack 232 to move towards the direction close to the first locking seat 33. Under the action of the gear 233, the second rack 234 drives the first locking pin 31 to move away from the first locking seat 33 to unlock the first locking pin 31 from the door frame. At the same time, since the connecting rod groove 21 moves towards the direction close to the first locking seat 33, it drives the connecting rod 22 to move away from the second locking seat 34. Further, the second locking pin 32 moves away from the second locking seat 34, so that the second locking pin 32 is unlocked from the second locking seat 34. At the same time, the lock tongue 14 also disengages from the door frame as the lock core 12 rotates, realizing the unlocking of the lock.

[0078] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
