Description

Technical Field

[0001] This invention belongs to the field of child safety products, specifically relating to a method for unlocking and locking cabinets that can be used to lock cabinet door handles. Background Technology

[0002] Kitchen cabinets are a common household product, bringing convenience to people's lives, but they also pose certain safety issues, mainly the tidying up trouble and safety hazards caused by children opening them without permission. Children are naturally curious, love new things, and enjoy exploring; while playing, they may open cabinet doors or drawers. This can not only mess up previously organized items, but more seriously, it can create safety hazards, such as items inside the cabinet being unsafe for children, sharp edges causing injury, or children locking themselves inside the cabinet.

[0003] For example, Chinese invention patent CN205330314U discloses a lever-type cabinet lock. This lever-type cabinet lock is designed with two unlocking buttons and requires a predetermined operating method to unlock, avoiding the inconvenience of using a key and preventing children from operating it without authorization. However, existing cabinet locks are not convenient to operate and have only one unlocking method. Summary of the Invention

[0004] This invention relates to a cabinet unlocking and locking method that is convenient to operate and has a novel unlocking method.

[0005] A method for unlocking and locking a cabinet, including unlocking and locking operations, specifically including the following steps:

[0006] The cabinet lock is configured to include a first locking member and a second locking member. The first locking member includes a base rod and a first rod portion and a second rod portion disposed at both ends thereon. The second locking member, after engaging with the first locking member, forms a cavity. The two ends of the cavity are respectively formed as a first locking portion and a second locking portion for engaging with the two handles of the cabinet to lock the two handles. The second locking member includes a first seat portion and a second seat portion. The first seat portion and the second seat portion are respectively provided with a first guide portion and a second guide portion. The first guide portion and the second guide portion are movably disposed along the first rod portion and the second rod portion, respectively.

[0007] The unlocking operation includes: operating the second locking member to move it outward relative to the first locking member to a predetermined position, so that the second locking member is limited to that position relative to the first locking member and cannot move further outward, the first seat part disengaging from the first rod part, and the second seat part rotating about the second rod part as a pivot to form an opening between the first seat part and the first rod part for the cabinet handle to be disengaged.

[0008] The locking operation includes: operating the second locking member to rotate it around the second rod portion to an angle aligned with the first locking member; pushing the second locking member to move inward relative to the first locking member so that the first guide portion engages with the first rod portion and moves along it, until the two handles of the cabinet are respectively located at the first locking portion and the second locking portion to be locked by the cabinet lock.

[0009] According to the above-mentioned cabinet unlocking and locking method, the length of the second seat is greater than the length of the first seat, so that when the first seat is displaced from the first rod, the second seat can be rotatably fitted onto the second rod with the second rod as the pivot.

[0010] According to the above-mentioned cabinet unlocking and locking method, the length of the second rod is greater than the length of the first rod, so that when the first seat is displaced from the first rod, the second seat can be rotatably fitted onto the second rod with the second rod as the pivot.

[0011] According to the above-mentioned cabinet unlocking and locking method, the first guide part or the second guide part is an O-shaped through hole or a C-shaped through hole, so that the second lock member slides along the first lock member.

[0012] According to the above-mentioned cabinet unlocking and locking method, the outer ends of the first rod and the second rod are respectively formed as the first rod end and the second rod end. The second rod end is also provided with a first limiting part, which includes a limiting protrusion and a limiting groove. The size of the limiting groove is smaller than that of the limiting protrusion, so that a groove is formed at the second rod end that surrounds or partially surrounds the second rod end.

[0013] According to the above-mentioned cabinet unlocking and locking method, the second guide part is also provided with a second limiting part that cooperates with the first limiting part. The protrusion of the second limiting part cooperates in the limiting groove to limit the sliding of the second locking member relative to the first locking member.

[0014] According to the above-described cabinet unlocking and locking method, during the unlocking operation, when the second locking member is moved outward relative to the first locking member to a predetermined position, the user manually operates to hold the second locking member in the predetermined position, and the opening is formed by rotating the second seat about the second rod as an axis. That is, the first limiting part and its two limiting mechanisms are omitted, and the same operation method is achieved through user-operated limiting. This only slightly increases the operational requirements compared to the above method; the main operation method remains unchanged.

[0015] According to the above-mentioned cabinet unlocking and locking method, the second limiting part is composed of a spring piece, one end of which is connected to the second locking member or integrally formed, and the other end is freely set; the free end of the spring piece is provided with a protrusion, which is engaged in the limiting groove to limit the position, so that a first gap is formed between the first seat and the first rod, and the second seat is rotatably engaged with the second rod about the second rod as the pivot.

[0016] According to the above-described cabinet unlocking and locking method, the top surface of the protrusion is recessed or has a planar shape.

[0017] Based on the above-mentioned cabinet unlocking and locking methods, the outer side of the limiting protrusion is either a slope or a spherical surface.

[0018] According to the above-mentioned cabinet unlocking and locking method, the first lock and the second lock are respectively provided with a third limiting part and a fourth limiting part. The third limiting part is a rack provided along the first rod part, and the fourth limiting part includes a toothed block for engaging with the rack.

[0019] According to the above-described cabinet unlocking and locking method, the fourth limiting part is provided on the outer side or front of the second locking member.

[0020] According to the above-mentioned cabinet unlocking and locking method, the fourth limiting part includes a first actuating part and a second actuating part. One end of the first actuating part is connected to the second locking member, and the other end is connected to one end of the second actuating part. The toothed block is formed on the first actuating part and is disposed adjacent to the first guide part to cooperate with the third limiting part disposed on the first rod part.

[0021] According to the above-mentioned cabinet unlocking and locking method, the fourth limiting part is integrally formed on the second locking member.

[0022] According to the above-mentioned cabinet unlocking and locking method, the other end of the second actuating part is also provided to protrude outward to form an actuating end, and a second gap is also formed between the fourth limiting part and the second locking member.

[0023] According to the above-mentioned cabinet unlocking and locking method, the toothed block has a limiting surface on the outer side and a guide surface on the inner side, and the toothed rack, which is the third limiting part, has a guide surface on the outer side and a limiting surface on the inner side.

[0024] According to the above-mentioned cabinet unlocking and locking method, the back of the second rod is also recessed with a third guide portion, and when the second lock slides relative to the first lock, the protrusion slides in the third guide portion.

[0025] The cabinet unlocking and locking method of the present invention has the following beneficial effects:

[0026] 1. In some embodiments, in the unlocked state, the second locking member does not disengage from the first locking member, but rather the second locking member rotates relative to the first locking member along the second rod portion as a pivot, thereby forming an opening that allows the handle to disengage, thus releasing the cabinet lock from locking the handle.

[0027] 2. The second locking component can slide within a predetermined length relative to the first locking component and form a locked state at any position within the range, thereby enabling the cabinet lock to match the locking of cabinet door handles of different specifications.

[0028] 3. The first and third limiting parts are set to one-way locking, so that when the second locking member slides inward, the fourth limiting part does not need to be operated to complete the adjustment of the locking setting of the second locking member.

[0029] 4. The cooperation of the first and second limiting parts ensures that the second locking part will not detach from the first locking part during daily use. This avoids the inconvenience of having to reposition the second locking part relative to the first locking part when locking again. Simply reset the second locking part and push it inward to complete the relocking operation. Attached Figure Description

[0046] The components include: a first locking member 10, a second locking member 20, a bottom rod 11, a first rod portion 12, a second rod portion 13, a third limiting portion 14, a first limiting portion 15, a first seat portion 21, a second seat portion 22, a fourth limiting portion 31, a second limiting portion 32, a cavity portion 100, a first locking portion 101, a second locking portion 102, an opening portion 103, a first gap 104, a third guide portion 111, a fourth guide portion 112, a first guide portion 201, a second guide portion 202, a limiting protrusion 151, a limiting groove 152, a first rod end 121, a second rod end 131, a first mating portion 201, a second mating portion 202, a first actuating portion 311, a second actuating portion 312, an actuating end 313, a toothed block 314, and a second gap 315. Detailed Implementation

[0047] To enable those skilled in the art to better understand the present invention and to more clearly define the scope of protection of the present invention, the present invention will be described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present invention, and are merely a part of the embodiments of the present invention. The specific and direct descriptions of related structures are only for the convenience of understanding the present invention, and the specific features do not necessarily or directly limit the scope of the present invention. Conventional choices and substitutions made by those skilled in the art under the guidance of the present invention should be considered within the scope of protection of the present invention.

[0048] A method for unlocking and locking a cabinet is provided. Unlocking is achieved by the outward displacement of a second locking member 20 relative to a first locking member 10 and its rotation around a second rod portion 13. This ensures that in the unlocked state, the second locking member 20 remains connected to the first locking member 10 rather than being separated, preventing the loss of parts and simplifying the unlocking operation. Locking is accomplished by performing the reverse operation of unlocking.

[0049] In order to ensure that the second locking member 20 is in a non-detachable movable position relative to the first locking member 10 during the unlocking operation, it can be achieved by setting two limiting structures that cooperate with each other to limit the movement, or by having the user operate the second locking member 20 to be held in the corresponding position.

[0050] In addition, the locking position between the second locking member 20 and the first locking member 10 is also adjustable, so that it can be adapted to the specifications of different cabinet doors.

[0051] The above-described methods for unlocking and locking the cabinet can be implemented based on the cabinet locks in the following embodiments.

[0052] Example 1

[0053] A cabinet lock is used to lock the two handles of the cabinet door to prevent children from opening the cabinet door and rummaging through items or causing safety problems.

[0054] like Figure 1 As shown, the cabinet lock comprises a first locking member 10 and a second locking member 20 that cooperate to form a racetrack-shaped cavity 100. The two ends of the cavity 100 form a first locking part 101 and a second locking part 102, respectively. The two locking parts 101 and 102 are used to house the two handles on the cabinet door, thereby achieving the purpose of locking the cabinet door. Furthermore, the engagement position of the second locking member 20 relative to the first locking member 10 is adjustable, making the length of the cavity 100 adjustable to accommodate cabinet doors of different specifications or models. When unlocking is required, the second locking member 20 is driven to move outward relative to the first locking member 10, causing it to disengage completely or partially from the first locking member 10, thus opening the cavity 100 from a sealed state, thereby achieving the purpose of unlocking.

[0055] In this embodiment, the cabinet lock is configured to unlock without requiring the two locking components to be completely separated.

[0056] like Figure 2As shown, the first locking member 10 includes a base rod 11 and a first rod portion 12 and a second rod portion 13 connecting the two ends of the base rod 11, forming a first locking member 10 with an overall U-shaped form. The second locking member 20 is J-shaped, which can be considered as a U-shaped form where one end is extended relative to the other end. The first locking member 10 and the second locking member 20 cooperate to form as shown. Figure 1 The locked state shown creates a racetrack-shaped cavity 100 between the two, which is closed around its perimeter. The cavity 100 is used to lock the two handles of the cabinet door within it, and its shape is not limited to that shown in the figure; it can also be other shapes.

[0057] In this embodiment, the two ends of the second locking member 20 are respectively formed as a first seat portion 21 and a second seat portion 22, and the length of the second seat portion 22 is greater than that of the first seat portion 21. The first seat portion 21 is provided with a first guide portion 201, and the second seat portion 22 is provided with a second guide portion 202. The first guide portion 201 and the second guide portion 202 are respectively used to engage with the first rod portion 12 and the second rod portion 13 to slide along them, so that the second locking member 20 can slide along the first locking member 10 to adjust the size of the cavity 100, that is, to adjust the distance between the first locking portion 101 and the second locking portion 102, so that the handles provided on the two cabinet doors are locked by the first locking portion 101 and the second locking portion 102.

[0058] like Figure 4 As shown, the outer ends of the first rod portion 12 and the second rod portion 13 of the first locking member 10 are respectively formed as a first rod end 121 and a second rod end 131, and the first seat portion 21 and the second seat portion 22 are respectively fitted onto the first rod end 121 and the second rod end 131 to slide along them. An opening portion 103 is formed between the first rod end 121 and the second rod end 131.

[0059] like Figure 5 As shown, in this embodiment, the first seat portion 21 and the second seat portion 22 are respectively provided with a first guide portion 201 and a second guide portion 202. Both guide portions are through holes to be sleeved on the first rod portion 12 or the second rod portion 13 and slide along the two rod portions. Of course, in other embodiments, it is also feasible to set the first mating portion 201 or the second mating portion 202 to have a C-shaped cross-section, which can also achieve the purpose of the second locking member 20 being slidable but not separable from the first locking member 10.

[0060] like Figure 2 , 4As shown, in this embodiment, the lengths of the first rod portion 12 and the second rod portion 13 are substantially equal. A first limiting portion 15 is also formed at the second rod portion 13. The first limiting portion 15 includes a limiting protrusion 151 and a limiting groove 152. The size of the limiting groove 152 is smaller than that of the limiting protrusion 151, so that a groove is formed around or partially around the second rod end 131.

[0061] like Figure 5-7 As shown, the second guide portion 202 of the second seat portion 22 is further provided with a second limiting portion 32 that cooperates with the first limiting portion 15. This limiting portion 32 is composed of a spring piece, one end of which is connected to or integrally formed with the second locking member 20, while the other end is freely disposed to elastically position relative to the second locking member 20. Furthermore, a protrusion is provided on the inner wall of the spring piece. In this embodiment, a U-shaped gap groove is formed between the second limiting portion 32 and the second locking member 20 to form the spring piece and thus constitute the second limiting portion 32. The second limiting portion 32, composed of the spring piece, can form a limiting relationship during normal use to prevent further displacement of the second locking member 20 relative to the first locking member 10. When the user applies greater pulling force, the spring piece can be separated from the first limiting portion 15, allowing the second locking member 20 to disengage from the first locking member 10.

[0062] When the second locking member 20 slides outward relative to the first locking member 10, the protrusion of the second limiting part 32 engages with the limiting groove 152 and is limited by the limiting protrusion 151, preventing it from dislodging from the second rod part 13. At this time, the first seat part 21 and the first rod end 121 separate to form a first gap 104, allowing the second locking member 20 to rotate relative to the first locking member 10 so that the gap between the first seat part 21 and the first rod end 121 is widened by rotation, thereby allowing the handle of the cabinet door located at the second locking part 102 to dislodge. Further operation can also dislodge the other handle from the cavity 100, thereby removing the cabinet lock from the cabinet door or separating it from the handle of one of the cabinet doors.

[0063] When the second locking member 20 rotates 180°, it will form the following shape: Figure 8 In the state shown, the handle can be disengaged from the cabinet lock to unlock it or the cabinet lock can be removed from the cabinet door, but the second locking piece 20 is still engaged with the first locking piece 10, and the two are not disengaged from each other.

[0064] To allow the second locking member 20 to be adjusted and locked relative to the first locking member 10 within a certain range, the first locking member 10 and the second locking member 20 are respectively provided with a third limiting part 14 and a fourth limiting part 31. The third limiting part 14 is a rack arranged along the first rod part 12, and the fourth limiting part 31 includes a toothed block 314 that can cooperate with the rack, thereby adjusting the relative distance between the two locking members by the different positions of the toothed block 314 on the rack. In this embodiment, the fourth limiting part 31 is provided on the outer surface of the second locking member 20 for ease of operation. Of course, in other embodiments, it can also be provided on the front surface of the second locking member 20, which is also convenient for operation.

[0065] like Figure 6 , 7 As shown, the fourth limiting portion 31 includes a first actuating portion 311 and a second actuating portion 312. One end of the first actuating portion 311 is connected to the second locking member 20, and the other end is connected to one end (i.e., its first end) of the second actuating portion 312, to form a fourth limiting portion 31 that is generally L-shaped. Preferably, the fourth limiting portion 31 is integrally formed on the second locking member 20.

[0066] In this embodiment, the toothed block 314 is formed on the first actuating part 311 and disposed adjacent to the first guide part 201 to cooperate with the third limiting part 14 disposed on the first rod part 12. The second end of the second actuating part 312 (i.e., the other end opposite to the connecting end of the first actuating part 311) is also provided to protrude outward to form an actuating end 313 to facilitate operation of the fourth limiting part 31. Furthermore, a second gap 315 is formed between the fourth limiting part 31 and the second locking member 20 so that the fourth limiting part 31 is relatively movably disposed in the second locking member 20. In the initial case, the toothed block 314 is in the mating position relative to the first rod part 12 so that the toothed block 314 cooperates with the third limiting part 14 to lock the second locking member 20 relative to the first locking member 10 in at least one direction. When the fourth limiting part 31 is operated to displace the toothed block 314 away from the rack, the second locking member 20 can slide freely relative to the first locking member 10.

[0067] In this embodiment, the toothed block 314 has a limiting surface on its outer side and a guide surface on its inner side. The rack, serving as the third limiting part 14, has a guide surface on its outer side and a limiting surface on its inner side. When the second locking member 20 approaches the first locking member 10, the toothed block 314 slides along the rack through the interaction of their guide surfaces. When there is relative movement, the relative movement between them is locked by the cooperation of their limiting surfaces. Therefore, in this embodiment, the toothed block and rack are a one-way locking structure. Inward relative movement can be achieved by pushing, while outward relative movement requires operation to unlock the fourth limiting part 31. The limiting surface is a plane perpendicular to the axis of the first rod, and the guide surface is an inclined surface or a curved surface.

[0068] Of course, in other embodiments, only one of the toothed block and rack may have a guide surface, which can also achieve the purpose of unidirectional locking. Alternatively, neither the toothed block nor the rack has a guide surface, and both inward and outward relative movement require operation of the fourth limiting part 31 to unlock.

[0069] like Figure 7 As shown, in this embodiment, the top surface of the protrusion of the second limiting part 32 is concave, so that when it is engaged with the limiting groove 152, the two can have good limiting contact and prevent the second locking member 20 from accidentally coming off.

[0070] In this embodiment, a third guide portion 111 is recessed on the back side of the second rod portion 13. The third guide portion 111 is used to allow the protrusion of the second limiting portion 32 to slide within it when the second locking member 20 slides relative to the first locking member 10. Furthermore, a fourth guide portion 112 is provided on the outer side of the third guide portion 111, which is formed by an inclined surface or a curved surface to guide the second limiting portion 32 when it is engaged or disengaged from the third guide portion 111. Figure 4 As shown, the third guide portion 111 also extends into the limiting groove 152 to form a connecting groove 105, so as to facilitate the second limiting portion 32 to switch between the third guide portion 111 and the limiting groove 152.

[0071] In this embodiment, the outer side of the limiting protrusion 151 is a slope or a spherical surface, so that when the separated second locking member 20 is engaged relative to the first locking member 10, it interacts with the protrusion of the second limiting part 32 to guide it, so that the protrusion can be automatically engaged into the limiting groove 152, avoiding the inconvenience of manually operating the protrusion and optimizing the user experience.

[0072] The cabinet lock operation process (i.e., unlocking and locking methods) in this embodiment is as follows:

[0073] 1. When the second locking member 20 and the first locking member 10 are separated, they are two independent components. By correspondingly engaging the first seat 21 with the first rod 12 and the second seat 22 with the second rod 13, the two components can be combined to form the entire cabinet lock.

[0074] 2. When the handles on the two cabinet doors are engaged in the cavity 100, applying force causes the second locking member 20 to move inward relative to the first locking member 10, locking the two handles with the first locking part 101 and the second locking part 102, thus locking the cabinet doors to open. During this process, the toothed block 314 and the rack can be automatically unlocked during sliding adjustment by the guide surface or by operating the fourth limiting part 31.

[0075] 3. When unlocking is required, first operate the fourth limiting part 31 to release the locking relationship between the toothed block 314 and the rack, then apply force to the second locking member 20 to make it move outward relative to the first locking member 10 until the first seat part 21 and the first rod end 121 are separated from each other. At this time, the protrusion engages in the limiting groove 152 to allow the second locking member 20 to rotate around the second rod part 13 as the axis, so that the distance between the first seat part 21 and the first rod end 121 increases and one of its handles is disengaged from the cavity 100, thereby allowing the cabinet door to be opened or the cabinet lock to be removed from the cabinet door.

[0076] 4. In this embodiment, the second locking component and the first locking component remain connected in the unlocked state, which avoids the loss of parts and simplifies the unlocking operation.

[0077] 5. When locking is required, first place both handles in the cavity 100, and rotate the second locking member 20 around the second rod 13 until the first seat 21 and the first rod end 121 are in corresponding positions; then apply force to make the second locking member 20 slide inward relative to the first locking member 10 until the two handles are respectively located at the first locking part 101 and the second locking part 102.

[0078] Example 2

[0079] like Figure 9-10 As shown, a cabinet lock has the same main structure as Embodiment 1, except that in this embodiment, the top surface of the protrusion of the second limiting part 32 is flat. In this embodiment, when the protrusion engages with the limiting groove 152, the second locking member 20 is limited relative to the first locking member 10 mainly by the middle part of the protrusion engaging in the limiting groove 152. Its engagement force is weaker than that of Embodiment 1, but it does not affect the function of the cabinet lock, and it is advantageous when disassembling the two locking members.

[0080] Example 3

[0081] like Figure 11-15As shown, a cabinet lock has the same main structure as Embodiment 1, except that: in this embodiment, the second locking member 20 is U-shaped (i.e., the lengths of the first seat 21 and the second seat 22 are equal), while the lengths of the two rods of the first locking member 10 are unequal (i.e., the lengths of the first rod 12 and the second rod 13 are unequal, one is shorter and the other is longer), thereby achieving the same purpose as Embodiment 1, allowing relative rotation to unlock without disengaging the two locking members.

[0082] In this embodiment, the main structures of the first locking member 10 and the second locking member 20 remain unchanged, but the length of the second rod portion 13 is greater than that of the first rod portion 12, and the first seat portion 21 and the second seat portion 22 of the second locking member 20 are set to have almost the same length. When the second locking member 20 slides outward relative to the first locking member 10 until the protrusion of the second limiting portion 32 engages in the limiting groove 152, the first seat portion 21 disengages from the first rod end 121, forming a first gap 104 between them. This allows the second locking member 20 to rotate around the second rod portion 13 as a pivot, thereby forming an opening between the first seat portion 21 and the first rod end 121 for the handle to be disengaged.

[0083] Therefore, the difference between this embodiment and Embodiment 1 is that the load-bearing structures of the first locking member 10 and the second locking member 20 when they rotate relative to each other are different, but the main functional components are the same.

[0084] In this embodiment, since the first seat 21 and the second seat 22 are of equal length, the second locking member 20 can also be square in shape.

[0085] Example 4

[0086] A cabinet lock, whose main structure is the same as that of Embodiment 1 or 3, differs in that: in this embodiment, the first rod portion 12 and the second rod portion 13 of the first locking member 10, and the first seat portion 21 and the second seat portion 22 of the second locking member 20 are all arranged with one short and one long, and the longer ones correspond to each other. Thus, after the first locking member 10 and the second locking member 20 work together to achieve the above-mentioned displacement to the designated position, the second locking member 20 is allowed to rotate relative to the first locking member 10 about the second rod portion 13 as the pivot to unlock.

[0087] In other words, in Embodiment 1 or 3, the purpose of displacement and rotation to unlock is achieved by extending the length of the second rod portion 13 or the second seat portion 22. In this embodiment, the purpose of displacement and rotation to unlock is achieved by extending the lengths of both the second rod portion 13 and the second seat portion 22.

[0088] Example 5

[0089] like Figure 16As shown, a cabinet lock has the same main structure as Embodiment 1, except that in this embodiment, the third limiting part 14 is moved from the lower end face of the first rod part 12 to the interior of the first rod part 12. That is, in this embodiment, the setting position of the third limiting part 14 is different.

[0090] Example 6

[0091] A cabinet lock, whose main structure is the same as that of Embodiments 1, 3 or 4, differs in that: in this embodiment, the cabinet lock does not have a first limiting part 15 and a second limiting part 32.

[0092] That is, in this embodiment, the second locking member 20 can freely disengage from the first locking member 10 after being displaced outward relative to the first locking member 10, and will not be limited and unable to disengage due to the interaction between the first limiting part 15 and the second limiting part 32 as in embodiments one, three or four.

[0093] In this embodiment, the length of the second rod portion 13 relative to the first rod portion 12, and / or the length of the second seat portion 22 relative to the first seat portion 21, can also exist. This structural design allows the user to manually control the second locking member 20 to stop it at a position where the first seat portion 21 is separated from the first rod portion 12, achieving an operational effect similar to that described in embodiments one, three, or four. In other words, in this embodiment, the operation of the cabinet lock is similar to embodiments one, three, or four, except that embodiments one, three, or four have corresponding limiting structures (i.e., the first limiting portion 15 and the second limiting portion 32) to limit the second locking member 20, while this embodiment does not have such limiting structures. Instead, the user needs to manually control the displacement of the second locking member 20 to achieve the same operational purpose.

[0094] It should be noted that although the second locking member 20 or the first locking member 10 is described as having a U-shaped shape in the above embodiments, the U-shaped shape is a general approximate shape for the cabinet locks in each embodiment, and slight variations in details are allowed. For example, in Embodiment 1, the bottom rod 11 and the first rod portion 12 are formed at a near right angle.

[0095] Furthermore, in other embodiments, the cabinet lock does not form an opening by rotation of the second locking member 20 relative to the first locking member 10, but rather by further extending the second rod portion 13 or the second seat portion 22 to form an opening between the first seat portion 21 and the first rod end 121 for the handle to be disengaged.
