Description

Technical Field

[0001] The utility model relates to the field of door locks, in particular to a door lock, a door structure and a refrigerator. Background Art

[0002] Some existing door bodies can be opened from both the left and right sides respectively. For example, some refrigerator doors can adapt to more usage scenarios and user habits, and this design can prevent the door body from being blocked when opened. However, when users operate abnormally and operate the unlocking structures on both sides simultaneously, both sides of the door body are unlocked, resulting in the door body falling off, which poses a certain safety hazard. Summary of the Utility Model

[0003] In order to overcome the deficiencies in the prior art, the utility model provides a door lock which can effectively prevent the first control member and the second control member from being simultaneously in the first unlocking control position and the second unlocking control position respectively by setting a limiting member, thus avoiding the door body being disassembled from the door frame by the user due to misoperation. The utility model also provides a door structure and a refrigerator.

[0004] To achieve the above object, the utility model adopts the following technical solutions:

[0005] A door lock, comprising:

[0006] A first lock body, which is arranged between the first door frame side of the door frame and the first door body side of the door body on the same side as the first door frame side, and the first lock body has a first locked state that restricts the separation of the first door frame side and the first door body side, and a first unlocked state that allows the separation of the first door frame side and the first door body side;

[0007] A second lock body, which is arranged between the second door frame side of the door frame opposite to the first door frame side and the second door body side of the door body on the same side as the second door frame side, and the second lock body has a second locked state that restricts the separation of the second door frame side and the second door body side, and a first unlocked state that allows the separation of the second door frame side and the second door body side;

[0008] A first control member, which is movably arranged and has a first locking control position that makes the first lock body in the first locked state and a first unlocking control position that makes the first lock body in the first unlocked state during the movement;

[0009] A second control member, which is movably arranged and has a second locking control position that makes the second lock body in the second locked state and a second unlocking control position that makes the second lock body in the second unlocked state during the movement;

[0010] A restricting member, which is movably arranged and has a first restricting position for restricting the movement of the first control member to the first unlocking control position and a second restricting position for restricting the movement of the second control member to the second unlocking control position during the movement; during the process of the first control member moving to the first unlocking control position, the first control member acts on the restricting member to make it move to the second restricting position, and during the process of the second control member moving to the second unlocking control position, the second control member acts on the restricting member to make it move to the first restricting position.

[0011] With the above structure, during use, the user can operate the first control member to move it to the first unlocking control position, so that the first lock body is in the first unlocking state. At this time, the first door body side of the door body and the first door frame side of the door frame are allowed to be separated, that is, the user can open the door body from this side; the user can also operate the second control member to move it to the second unlocking control position, so that the second lock body is in the second unlocking state. At this time, the second door body side of the door body and the second door frame side of the door frame are allowed to be separated, that is, the user can open the door body from this side; thus, the user can open the door body from both sides, which is more flexible and convenient for the user to use.

[0012] In the above structure, the setting of the restricting member can effectively prevent the first control member and the second control member from being simultaneously in the first unlocking control position and the second unlocking control position respectively, avoiding the user's misoperation to disassemble the door body from the door frame; specifically, when the user operates the first control member to move it to the first unlocking control position, the restricting member will move to the second restricting position to restrict the second control member, so that the user cannot operate the second control member to move it to the second unlocking control position at this time; the same is true when the user operates the second control member, the first control member cannot move to the first unlocking control position; and when the user operates the first control member or the second control member to open the door body from one side, subjectively, the user will not operate the other one; if the user wants to disassemble the door body, only need to first operate the first control member or the second control member to open the door body from one side, and reset the first control member or the second control member, and then operate the first control member and the other one of the first control members to disassemble the door body, so as to facilitate the user's choice according to their own needs, and at the same time facilitate the maintenance, repair and other operations of the door body.

[0013] Further, the first control member is provided with a first restricting linkage part, and the second control member is provided with a second restricting linkage part; the restricting member has a first restricting part cooperating with the first restricting linkage part and a second restricting part cooperating with the second restricting linkage part.

[0014] During the process that the first control member moves to the first unlocking control position, the first limiting linkage acts on the first limiting portion to cause the limiting member to move to a position where the second limiting portion is located in the movement track of the second limiting linkage when the second control member moves from the second locking control position to the second unlocking control position;

[0015] During the process that the second control member moves to the second unlocking control position, the second limiting linkage acts on the second limiting portion to cause the limiting member to move to a position where the first limiting portion is located in the movement track of the first limiting linkage when the first control member moves from the first locking control position to the first unlocking control position.

[0016] With the above structure, when the user operates the first control member to move it to the first unlocking control position, the first limiting linkage on the first control member will act on the limiting member to cause it to move. At this time, the second limiting portion of the limiting member will be located on the movement track of the second limiting linkage. If the user operates the second control member, the second limiting linkage will contact the second limiting portion, making the second limiting linkage unable to continue moving to this side, that is, making the second control member unable to move to the second unlocking control position; operating the second control member to limit the first control member is the same reason.

[0017] Further, when the first control member moves, the first limiting linkage approaches or moves away from the second limiting linkage. And when the first control member moves from the first locking control position to the first unlocking control position, the first limiting linkage moves in the first linkage direction. Along the first linkage direction, the first limiting linkage sequentially includes a first limiting linkage side and a second limiting linkage side;

[0018] When the second control member moves, the second limiting linkage approaches or moves away from the first limiting linkage; and when the second control member moves from the second locking control position to the second unlocking control position, the second limiting linkage moves in the second linkage direction. Along the second linkage direction, the second limiting linkage sequentially includes a third limiting linkage side and a fourth limiting linkage side;

[0019] The limiting member can reciprocate along the direction from the first limiting linkage to the second limiting linkage. The first limiting portion of the limiting member is oppositely arranged with the second limiting linkage side, and the second limiting portion of the limiting member is oppositely arranged with the fourth limiting linkage side;

[0020] When the first control member is located at the first unlocking control position and the second control member is located at the second unlocking control position, the distance between the second limiting linkage side opposite to the first limiting portion and the fourth limiting linkage side opposite to the second limiting portion is D1; when the first control member is located at the first locking control position and the second control member is located at the second unlocking control position, the distance between the second limiting linkage side opposite to the first limiting portion and the fourth limiting linkage side opposite to the second limiting portion is D2; when the first control member is located at the first unlocking control position and the second control member is located at the second locking control position, the distance between the second limiting linkage side opposite to the first limiting portion and the fourth limiting linkage side opposite to the second limiting portion is D3; the distance between the first limiting portion and the second limiting portion is D4;

[0021] If the second limiting linkage side is opposite to the fourth limiting linkage side, D4 is greater than D1, but D4 is less than or equal to D2, and D4 is less than or equal to D3;

[0022] If the second limiting linkage side is in a state opposite to the fourth limiting linkage side, D4 is smaller than D1, but D4 is greater than or equal to D2, and D4 is greater than or equal to D3.

[0023] The above structure makes the setting of the limiting member more reasonable;

[0024] When the second limiting linkage side is opposite to the fourth limiting linkage side, when the first control member moves to the first unlocking control position, the first limiting linkage part moves toward the second limiting linkage part, and when the second control member moves to the second unlocking control position, the second limiting linkage part moves toward the first limiting linkage part. Since D4 is less than or equal to D2 and D4 is less than or equal to D3, when the user operates the first control member or the second control member alone, the limiting member will not affect the first control member or the second control member; when the user operates the first control member to move to the first unlocking control position, the first limiting linkage part moves toward the second limiting linkage part and acts on the first limiting end, so that the limiting member also moves toward the second limiting linkage part. At this time, since D4 is greater than D1, the distance between the second limiting end and the second limiting linkage part cannot meet the travel required by the second limiting linkage part when the second control member moves to the second unlocking control position, that is, the second limiting part is located in the activity trajectory of the second limiting linkage part to limit the second limiting part, thereby limiting the second control member; the same applies to the operation of the second control member;

[0025] When the second restricted linkage side and the fourth restricted linkage side are in a state of facing away from each other, that is, when the first restricted linkage side and the third restricted linkage side are opposite to each other; when the first control member moves to the first unlocking control position, the first restricted linkage portion moves away from the second restricted linkage portion side. When the second control member moves to the second unlocking control position, the second restricted linkage portion moves away from the first restricted linkage portion side. Since D4 is greater than or equal to D2 and D4 is greater than or equal to D3, when the user operates the first control member or the second control member alone, the restricting member will not affect the first control member or the second control member; when the user operates the first control member to move it to the first unlocking control position, the first restricted linkage portion moves away from the second restricted linkage portion side and acts on the first restricting end, causing the restricting member to also move away from the second restricted linkage portion side. At this time, since D4 is less than D1, the distance between the second restricting end and the second restricted linkage portion cannot meet the required stroke of the second restricted linkage portion when the second control member moves to the second unlocking control position, that is, the second restricting portion is located in the movement trajectory of the second restricted linkage portion to restrict the second restricting portion, thereby restricting the second control member; the same applies to operating the second control member.

[0026] Further, the door lock includes a guiding member, and the guiding member extends along the direction from the first restricted linkage portion to the second restricted linkage portion, and the restricting member is slidably engaged with the guiding member.

[0027] With the above structure, the arrangement of the guiding member makes the movement of the restricting member more stable, reliable and smooth.

[0028] Further, the guiding member is provided with a guiding hole matching the guiding member, and the guiding hole extends along the direction from the first restricted linkage portion to the second restricted linkage portion, and the restricting member is inserted into the guiding hole.

[0029] With the above structure, the movement of the restricting member is restricted and guided through the arrangement of the guiding hole, making its movement stable, reliable and smooth.

[0030] Further, the door lock includes a first control mounting member for mounting the first control member and a second control mounting member for mounting the second control member.

[0031] With the above structure, the arrangements of the first control mounting member and the second control mounting member provide a mounting basis for the mounting of the first control member and the second control member.

[0032] Further, the first limiting linkage part of the first control member is located in the first control mounting member, and the first control mounting member is provided with a first mating perforation that matches the first limiting part for it to enter and cooperate with the first limiting linkage part; the second limiting linkage part of the second control member is located in the second control mounting member, and the second control mounting member is provided with a second mating perforation that matches the second limiting part for it to enter and cooperate with the second limiting linkage part.

[0033] Adopting the above structure makes the structures of the first control mounting member and the second control mounting member more reasonable; the setting of the first mating perforation facilitates the mutual cooperation between the first limiting part and the first limiting linkage part; the setting of the second mating perforation facilitates the mutual cooperation between the second limiting part and the second limiting linkage part.

[0034] Further, the first control mounting member is provided with a first guiding abutting part, the second control mounting member is provided with a second guiding abutting part, and the distance between the first guiding abutting part and the second guiding abutting part matches the length of the guiding member, and both ends of the guiding member respectively abut against the first guiding abutting part and the second guiding abutting part.

[0035] Adopting the above structure, the settings of the first guiding abutting part and the second guiding abutting part facilitate the installation and fixation of the guiding member.

[0036] Further, the first control mounting member is convexly provided with first guiding protrusions on both sides of the first limiting part; the second control mounting member is convexly provided with second guiding protrusions on both sides of the second limiting part.

[0037] Adopting the above structure, the first guiding protrusion can guide the movement of the first limiting part, and the second guiding protrusion can guide the movement of the second limiting part; the above structure makes the movement of the limiting member more stable and reliable.

[0038] Further, the first control mounting member is recessed at a position corresponding to the first limiting linkage part to form a first limiting linkage mating chute that matches the movement track of the first limiting linkage part; the second control mounting member is recessed at a position corresponding to the second limiting linkage part to form a second limiting linkage mating chute that matches the movement track of the second limiting linkage part.

[0039] Adopting the above structure, the settings of the first limiting linkage mating chute and the second limiting linkage mating chute can limit and guide the movements of the first limiting linkage part and the second limiting linkage part, making the movements of the first limiting linkage part and the second limiting linkage part more stable and reliable.

[0040] Furthermore, the first control member includes a first drive shaft for controlling the state of the first lock body, and a first operating member disposed on the first drive shaft to drive its movement. The first limiting linkage portion is disposed on the first operating member. The first control mounting member is recessed to form a first operating member mounting groove for accommodating and mounting the first operating member. The first drive shaft passes through the first operating member mounting groove and is connected to the first lock body to control its state;

[0041] The second control member includes a second drive shaft for controlling the state of the second lock body, and a second operating member disposed on the second drive shaft to drive its movement. The second limiting linkage portion is disposed on the second operating member. The second control mounting member is recessed to form a second operating member mounting groove for accommodating and mounting the second operating member. The second drive shaft passes through the second operating member mounting groove and is connected to the second lock body to control its state.

[0042] With the above structure, the structures of the first control member and the second control member are more reasonable, facilitating user operation and controlling the first lock body and the second lock body; the settings of the first operating member mounting groove and the second operating member mounting groove can better accommodate the first operating member and the second operating member, thereby realizing the installation of the first control member and the second control member.

[0043] Furthermore, the first door lock includes a first lock body member and a second lock body member. The first lock body member includes a first mating lock portion, and the second lock body member includes a second mating lock portion. One of the first lock body member and the second lock body member is disposed on the first door frame side, and the other of the first lock body member and the second lock body member is disposed on the first door body side. The first lock body member is movably disposed, and during the movement of the first lock body member, there is a first locking position where the first mating lock portion and the second mating lock portion are locked, and a first unlocking position where the first mating lock portion and the second mating lock portion are unlocked. That is, when the first lock body member moves to the first locking position, the first lock body is in the first locked state; when the first lock body member moves to the first unlocking position, the first lock body is in the first unlocked state; the first control member is connected to the first lock body member to drive its movement;

[0044] The second door lock includes a third lock body member and a fourth lock body member. The third lock body member includes a third mating lock portion, and the fourth lock body member includes a fourth mating lock portion. One of the third lock body member and the fourth lock body member is disposed on the second door frame side, and the other of the third lock body member and the fourth lock body member is disposed on the second door body side. The third lock body member is movably disposed, and during the movement of the third lock body member, there is a second locking position where the third mating lock portion and the fourth mating lock portion are locked, and a second unlocking position where the third mating lock portion and the fourth mating lock portion are unlocked. That is, when the third lock body member moves to the second locking position, the second lock body is in the second locked state; when the third lock body member moves to the second unlocking position, the second lock body is in the second unlocked state; the second control member is connected to the third lock body member to drive its movement.

[0045] With the above structure, the structures of the first lock body and the second lock body are more reasonable. When the first door frame side and the first door body side are closed, the first lock body member is located at the first locking position so that the first mating lock portion is locked and engaged with the second mating lock portion of the second lock body member to achieve the locking of the first door frame side and the first door body side; when the user operates the first control member, the first control member drives the first lock body member to move to the first unlocking position. At this time, the first mating lock portion and the second mating lock portion of the second lock body member are unlocked, and the user can separate the first door body side and the first door frame side, that is, the user can open the door body from this side; the same applies to the second lock body.

[0046] Further, one of the first mating lock portion and the second mating lock portion is configured as a first lock post; the other of the first door frame locking portion and the first door body locking portion is configured as a first lock hook, and the first lock hook is provided with a first card slot matching the first lock post; the first mating lock portion can approach and move away from the second mating lock portion along with the movement of the first lock body member, and when the first mating lock portion approaches the second mating lock portion, the first lock post is inserted into the first card slot, and when the first mating lock portion moves away from the second mating lock portion, the first lock post is separated from the first card slot;

[0047] One of the third mating lock portion and the fourth mating lock portion is configured as a second lock post; the other of the third door frame locking portion and the fourth door body locking portion is configured as a second through lock hook, and the first lock hook is provided with a first card slot matching the first lock post; the third mating lock portion can approach and move away from the fourth mating lock portion along with the movement of the third lock body member, and when the third mating lock portion approaches the fourth mating lock portion, the second lock post is inserted into the second card slot, and when the third mating lock portion moves away from the fourth mating lock portion, the second lock post is separated from the second card slot.

[0048] Adopting the above structure makes the structures of the first mating lock portion and the second mating lock portion, as well as the structures of the third mating lock portion and the fourth mating lock portion, more reasonable and reliable; when the first locking post is inserted into the first card slot, the first mating lock portion and the second mating lock portion are locked and matched; when the first locking post disengages from the first card slot, the first mating lock portion and the second mating lock portion are unlocked and matched; when the second locking post is inserted into the second card slot, the third mating lock portion and the fourth mating lock portion are locked and matched; when the second locking post disengages from the second card slot, the third mating lock portion and the fourth mating lock portion are unlocked and matched.

[0049] Further, when the first mating lock portion is configured as the first locking hook, the first lock body further includes a first locking post chute that matches the first locking post for the first locking post to slide in or out. The first locking hook is disposed on one side of the first locking post chute. When the first lock body moves to the first locking position, the first locking hook enters the first locking post chute, and the opening of the first card slot faces the side wall of the first locking post chute. When the first lock body moves to the first unlocking position, the first locking hook leaves the first locking post chute;

[0050] When the third mating lock portion is configured as the second locking hook, the third lock body further includes a second locking post chute that matches the second locking post for the second locking post to slide in or out. The second locking hook is disposed on one side of the second locking post chute. When the third lock body moves to the second locking position, the second locking hook enters the second locking post chute, and the opening of the second card slot faces the side wall of the second locking post chute. When the third lock body moves to the second unlocking position, the second locking hook leaves the second locking post chute.

[0051] Adopting the above structure, when the first doorframe side and the first door body side are in the closed state, the first locking post enters the first locking post chute, and the first locking hook enters the first locking post chute to lock the first locking post. And because the opening of the first card slot faces the side wall of the first locking post chute, the first locking post cannot move radially. At this time, the first locking post, the first locking hook, and the first locking post chute form a rotating shaft structure to realize the rotation when the door body is opened from the second door body side; the cooperation of the second locking post, the second locking hook, and the second locking post chute is the same.

[0052] Specifically, when the first lock body member is provided on the door body, the first lock post chute is formed on the door body; when the first lock body member is provided on the door frame, the first lock post chute is formed on the door frame; when the second lock body member is provided on the door body, the second lock post chute is formed on the door body; when the second lock body member is provided on the door frame, the second lock post chute is formed on the door frame. At the position where the first lock body member is provided, there is a first lock body member installation groove for installing and providing its movement space, and a part of the first lock body member installation groove forms the first lock post chute. At the position where the second lock body member is provided, there is a second lock body member installation groove for installing and providing its movement space, and a part of the second lock body member installation groove forms the second lock post chute.

[0053] Further, the first mating lock portion can approach or move away from the second mating lock portion as the first lock body member moves to lock or unlock; the third mating lock portion can approach or move away from the fourth mating lock portion as the third lock body member moves to lock or unlock.

[0054] With the above structure, the structure of the door lock is made more reasonable.

[0055] Further, the first lock body member is rotatably arranged, and the first mating lock portion is arranged at a distance from the rotation axis of the first lock body member;

[0056] The third lock body member is rotatably arranged, and the third mating lock portion is arranged at a distance from the rotation axis of the third lock body member.

[0057] With the above structure, it is realized that the first mating lock portion can approach or move away from the second mating lock portion as the first lock body member rotates, and the third mating lock portion can approach or move away from the fourth mating lock portion as the third lock body member rotates.

[0058] Further, the first control member includes a first drive shaft and a first operating member provided on the first drive shaft to drive the first drive shaft to rotate. The first drive shaft and the first lock body member are connected in a manner that restricts relative rotation, and the axis of the first drive shaft is collinear with the rotation axis of the first lock body member;

[0059] The second control member includes a second drive shaft and a second operating member provided on the second drive shaft to drive the second drive shaft to rotate. The second drive shaft and the third lock body member are connected in a manner that restricts relative rotation, and the axis of the second drive shaft is collinear with the rotation axis of the third lock body member.

[0060] Adopting the above structure makes the structures of the first control member and the second control member more reasonable; enabling a user to operate the first operating member to rotate the first drive shaft, and the rotation of the first drive shaft drives the first lock body member to rotate; the second control member drives the second lock body member in the same way; specifically, the cross-section of the first drive shaft is non-circular, and a first drive shaft mounting hole that matches the first drive shaft and is used for inserting the first drive shaft is provided on the first lock body member to achieve a rotationally restricted connection therebetween; the cross-section of the second drive shaft is non-circular, and a second drive shaft mounting hole that matches the second drive shaft and is used for inserting the second drive shaft is provided on the third lock body member to achieve a rotationally restricted connection therebetween; a mating sleeve is sleeved on the first drive shaft and the second drive shaft at the positions where they pass through the first operating member mounting groove and the second operating member mounting groove, and the inner hole of the mating sleeve matches the first drive shaft and the second drive shaft, and the outer side is a cylindrical arc surface, enabling the first drive shaft and the second drive shaft to rotate better; more specifically, the cross-sections of the first drive shaft and the second drive shaft are rectangular; the first operating mounting member forms a mating sleeve that mates with the first drive shaft, and the second operating mounting member forms a mating sleeve that mates with the second drive shaft.

[0061] Further, the first lock body member and the third lock body member are provided on the door panel. Correspondingly, the first control member and the second control member are provided on the door panel, and the limiting member is provided on the door panel.

[0062] Adopting the above structure makes the settings of the first lock body member, the third lock body member, the first control member and the second control member more reasonable and more in line with the user's usage habits.

[0063] Further, the first operating member includes a first operating member body and a first operating mounting member. The first operating mounting member is provided with a first drive mounting hole that matches the first drive shaft. The first operating mounting member is sleeved on the first drive shaft by relying on the first drive mounting hole and the two are restricted from rotating relative to each other. The first operating member body is provided on the first operating mounting member;

[0064] The second operating member includes a second operating member body and a second operating mounting member. The second operating mounting member is provided with a second drive mounting hole that matches the second drive shaft. The second operating mounting member is sleeved on the second drive shaft by relying on the second drive mounting hole and the two are restricted from rotating relative to each other. The second operating member body is provided on the second operating mounting member.

[0065] Adopting the above structure makes the structures of the first operating member and the second operating member more reasonable, facilitating actual production and installation. Specifically, the cross-sections of the first drive shaft and the second drive shaft are non-circular, and the first drive mounting hole and the second drive mounting hole respectively match the first drive shaft and the second drive shaft to achieve a restricted relative rotational connection therebetween. Specifically, the cross-sections of the first drive shaft and the second drive shaft are rectangular.

[0066] Further, the door lock includes a first reset member and a second reset member. When the first control member is not in the first locking control position, the first reset member acts on the first control member to make it have a tendency to move in the direction of the first locking control position; when the second control member is not in the second locking control position, the second reset member acts on the second control member to make it have a tendency to move in the direction of the second locking control position.

[0067] Specifically, the first reset member and the second reset member are elastic members.

[0068] Adopting the above structure makes the structure of the door lock more reasonable, enabling the first door lock or the second door lock to be automatically locked when the door body and the door panel are closed. Specifically, the first reset member is a torsion spring, which is sleeved on the first drive shaft and its two ends respectively abut between the first operating member and the first operating member mounting groove; the second reset member is a torsion spring, which is sleeved on the second drive shaft and its two ends respectively abut between the second operating member and the second operating member mounting groove.

[0069] Further, the first lock hook is provided with a first guiding surface that cooperates with the first lock post to guide it to move toward the first unlocking position side, and the second lock hook is provided with a second guiding surface that cooperates with the second lock post to guide it to move toward the first unlocking position side.

[0070] Adopting the above structure, when the user closes the door body, the first lock post acts on the first lock hook to make it move to the first unlocking position, or the second lock post acts on the second lock hook to make it move to the second unlocking position, so as to facilitate the entry of only the first lock post and the second lock post. Under the action of the first reset member and the second reset member, the first lock hook and the second lock hook are reset, so that the first lock post is located in the first card slot or the second lock post is located in the second card slot; the above structure facilitates the user's door closing operation.

[0071] Further, the door frame includes a first door frame and a second door frame located on opposite sides of the door body. Correspondingly, the first door lock is provided between the first side of the first door frame and the first side of the door body, and between the first side of the second door frame and the first side of the door body. The second door lock is provided between the second side of the first door frame and the second side of the door body, and between the second side of the second door frame and the second side of the door body.

[0072] With the above structure, the door lock structure is more reasonable.

[0096] The following describes the technical solutions provided by each embodiment of the present application in conjunction with the accompanying drawings.

[0097] Refer to Figures 1 to 8 , the present utility model provides a door lock, comprising:

[0098] A first lock body 1, which is disposed between a first doorframe side 100-1 of a doorframe 100 and a first door body side 200-1 of a door body 200 on the same side as the first doorframe side 100-1, and the first lock body 1 has a first locked state that restricts the separation of the first doorframe side 100-1 and the first door body side 200-1, and a first unlocked state that allows the separation of the first doorframe side 100-1 and the first door body side 200-1;

[0099] A second lock body 2, which is disposed between a second doorframe side 100-2 of the doorframe 100 opposite to the first doorframe side 100-1 and a second door body side 200-2 of the door body 200 on the same side as the second doorframe side 100-2, and the second lock body 2 has a second locked state that restricts the separation of the second doorframe side 100-2 and the second door body side 200-2, and a first unlocked state that allows the separation of the second doorframe side 100-2 and the second door body side 200-2;

[0100] A first control member 3, which is movably disposed, and has a first locking control position that makes the first lock body 1 in the first locked state and a first unlocking control position that makes the first lock body 1 in the first unlocked state during the moving process;

[0101] A second control member 4, which is movably disposed, and has a second locking control position that makes the second lock body 2 in the second locked state and a second unlocking control position that makes the second lock body 2 in the second unlocked state during the moving process;

[0102] A restricting member 5, which is movably disposed, and has a first restricting position that restricts the first control member 3 from moving to the first unlocking control position and a second restricting position that restricts the second control member 4 from moving to the second unlocking control position during the moving process; during the process of the first control member 3 moving to the first unlocking control position, the first control member 3 acts on the restricting member 5 to make it move to the second restricting position, and during the process of the second control member 4 moving to the second unlocking control position, the second control member 4 acts on the restricting member 5 to make it move to the first restricting position.

[0103] With the above structure, during use, the user can operate the first control member 3 to move it to the first unlocking control position, so that the first lock body 1 is in the first unlocked state. At this time, the first door body side 200-1 of the door body 200 and the first door frame side 100-1 of the door frame 100 are allowed to be separated, that is, the user can open the door body 200 from this side; the user can also operate the second control member 4 to move it to the second unlocking control position, so that the second lock body 2 is in the second unlocked state. At this time, the second door body side 200-2 of the door body 200 and the second door frame side 100-2 of the door frame 100 are allowed to be separated, that is, the user can open the door body 200 from this side; thus, the user can open the door body 200 from both sides, which is more flexible and convenient for the user to use;

[0104] In the above structure, the setting of the limiting member 5 can effectively prevent the first control member 3 and the second control member 4 from being respectively in the first unlocking control position and the second unlocking control position at the same time, and prevent the user from accidentally operating to disassemble the door body 200 from the door frame 100; specifically, when the user operates the first control member 3 to move it to the first unlocking control position, the limiting member 5 will move to the second limiting position to limit the second control member 4, so that the user cannot operate the second control member 4 to move it to the second unlocking control position at this time; the same is true when the user operates the second control member 4, and the first control member 3 cannot move to the first unlocking control position; and when the user operates the first control member 3 or the second control member 4 to open the door body 200 from one side, subjectively, the user will not operate the other; if the user wants to remove the door body 200, only need to first operate the first control member 3 or the second control member 4 to open the door body 200 from one side, and reset the first control member 3 or the second control member 4, and then operate the first control member 3 and the other of the first control member 3 to disassemble the door body 200, so as to facilitate the user's choice according to their own needs, and at the same time facilitate the maintenance, maintenance and other operations of the door body 200.

[0105] Furthermore, the first control member 3 is provided with a first limiting linkage portion 301, and the second control member 4 is provided with a second limiting linkage portion 401; the limiting member 5 has a first limiting portion 501 that cooperates with the first limiting linkage portion 301 and a second limiting portion 502 that cooperates with the second limiting linkage portion 401;

[0106] During the process of the first control member 3 moving to the first unlocking control position, the first limiting linkage portion 301 acts on the first limiting portion 501 to move the limiting member 5 to a position where the second limiting portion 502 is located in the movement trajectory of the second limiting linkage portion 401 when the second control member 4 moves from the second locking control position to the second unlocking control position;

[0107] During the process that the second control member 4 moves to the second unlocking control position, the second limiting linkage portion 401 acts on the second limiting portion 502 to move the limiting member 5 to a position where its first limiting portion 501 is located in the movement track of the first limiting linkage portion 301 when the first control member 3 moves from the first locking control position to the first unlocking control position.

[0108] With the above structure, when the user operates the first control member 3 to move it to the first unlocking control position, the first limiting linkage portion 301 on the first control member 3 will act on the limiting member 5 to move it. At this time, the second limiting portion 502 of the limiting member 5 will be located on the movement track of the second limiting linkage portion 401. If the user operates the second control member 4, the second limiting linkage portion 401 will contact the second limiting portion 502, making the second limiting linkage portion 401 unable to continue moving to this side, that is, making the second control member 4 unable to move to the second unlocking control position; operating the second control member 4 to limit the first control member 3 is the same principle.

[0109] Further, when the first control member 3 moves, the first limiting linkage portion 301 approaches or moves away from the second limiting linkage portion 401. And when the first control member 3 moves from the first locking control position to the first unlocking control position, the first limiting linkage portion 301 moves in the first linkage direction. Along the first linkage direction, the first limiting linkage portion 301 successively includes a first limiting linkage side 3011 and a second limiting linkage side 3012;

[0110] When the second control member 4 moves, the second limiting linkage portion 401 approaches or moves away from the first limiting linkage portion 301; and when the second control member 4 moves from the second locking control position to the second unlocking control position, the second limiting linkage portion 401 moves in the second linkage direction. Along the second linkage direction, the second limiting linkage portion 401 successively includes a third limiting linkage side 4011 and a fourth limiting linkage side 4012;

[0111] The limiting member 5 can reciprocate along the direction from the first limiting linkage portion 301 to the second limiting linkage portion 401. The first limiting portion 501 of the limiting member 5 is disposed opposite to the second limiting linkage side 3012, and the second limiting portion 502 of the limiting member 5 is disposed opposite to the fourth limiting linkage side 4012;

[0112] When the first control member 3 is in the first unlocking control position and the second control member 4 is in the second unlocking control position, the distance between the position on the second restricted linkage side 3012 opposite to the first restricting portion 501 and the position on the fourth restricted linkage side 4012 opposite to the second restricting portion 502 is D1; when the first control member 3 is in the first locking control position and the second control member 4 is in the second unlocking control position, the distance between the position on the second restricted linkage side 3012 opposite to the first restricting portion 501 and the position on the fourth restricted linkage side 4012 opposite to the second restricting portion 502 is D2; when the first control member 3 is in the first unlocking control position and the second control member 4 is in the second locking control position, the distance between the position on the second restricted linkage side 3012 opposite to the first restricting portion 501 and the position on the fourth restricted linkage side 4012 opposite to the second restricting portion 502 is D3; the distance between the first restricting portion 501 and the second restricting portion 502 is D4;

[0113] Referring to Figure 7 , in some embodiments, in a state where the second restricted linkage side 3012 and the fourth restricted linkage side 4012 are opposite to each other, D4 is greater than D1, but D4 is less than or equal to D2 and D4 is less than or equal to D3; wherein, Figure 7 In the second figure of Figure 7 , the left dashed line indicates that the first control member is in the first locking control position, the solid line indicates that the first control member is in the first unlocking control position, the right dashed line indicates that the second control member is in the second unlocking control position, and the solid line indicates that the second control member is in the second locking control position;

[0114] Referring to Figure 8 , in some embodiments, in a state where the second restricted linkage side 3012 and the fourth restricted linkage side 4012 are away from each other, D4 is less than D1, but D4 is greater than or equal to D2 and D4 is greater than or equal to D3; wherein, Figure 8 In the second figure of Figure 8 , the left dashed line indicates that the first control member is in the first locking control position, the solid line indicates that the first control member is in the first unlocking control position, the right dashed line indicates that the second control member is in the second unlocking control position, and the solid line indicates that the second control member is in the second locking control position.

[0115] With the above structure, the setting of the limiting member 5 is made more reasonable;

[0116] When the second limiting linkage side 3012 and the fourth limiting linkage side 4012 are in a relative state, when the first control member 3 moves to the first unlocking control position, the first limiting linkage portion 301 moves toward the side close to the second limiting linkage portion 401. When the second control member 4 moves to the second unlocking control position, the second limiting linkage portion 401 moves toward the side close to the first limiting linkage portion 301. Since D4 is less than or equal to D2 and D4 is less than or equal to D3, when the user operates the first control member 3 or the second control member 4 alone, the limiting member 5 will not affect the first control member 3 or the second control member 4. When the user operates the first control member 3 to move it to the first unlocking control position, the first limiting linkage portion 301 moves toward the side close to the second limiting linkage portion 401 and acts on the first limiting end, so that the limiting member 5 also moves toward the second limiting linkage portion 401 side. At this time, since D4 is greater than D1, the distance between the second limiting end and the second limiting linkage portion 401 cannot meet the stroke required by the second limiting linkage portion 401 when the second control member 4 moves to the second unlocking control position, that is, the second limiting portion 502 is located in the movement track of the second limiting linkage portion 401 to limit the second limiting portion 502, thereby limiting the second control member 4. The same is true for operating the second control member 4;

[0117] When the second restricted linkage side 3012 and the fourth restricted linkage side 4012 are in a state of facing away from each other, that is, when the first restricted linkage side 3011 and the third restricted linkage side 4011 are opposite to each other; when the first control member 3 moves to the first unlocking control position, the first restricted linkage portion 301 moves away from the second restricted linkage portion 401 side, and when the second control member 4 moves to the second unlocking control position, the second restricted linkage portion 401 moves away from the first restricted linkage portion 301 side. Since D4 is greater than or equal to D2 and D4 is greater than or equal to D3, when the user operates the first control member 3 or the second control member 4 alone, the restricting member 5 will not affect the first control member 3 or the second control member 4; when the user operates the first control member 3 to move it to the first unlocking control position, the first restricted linkage portion 301 moves away from the second restricted linkage portion 401 side and acts on the first restricted end, causing the restricting member 5 to also move away from the second restricted linkage portion 401 side. At this time, since D4 is less than D1, the distance between the second restricted end and the second restricted linkage portion 401 cannot meet the required stroke of the second restricted linkage portion 401 when the second control member 4 moves to the second unlocking control position, that is, the second restricting portion 502 is located in the movement trajectory of the second restricted linkage portion 401 to restrict the second restricting portion 502, thereby restricting the second control member 4; the same applies to operating the second control member 4.

[0118] Further, the door lock includes a guiding member 6, and the guiding member 6 is arranged to extend along the direction from the first restricted linkage portion 301 to the second restricted linkage portion 401, and the restricting member 5 is in sliding fit with the guiding member 6.

[0119] With the above structure, the arrangement of the guiding member 6 makes the movement of the restricting member 5 more stable, reliable and smooth.

[0120] Further, the guiding member 6 is provided with a guiding hole 601 that matches the guiding member 6, and the guiding hole 601 is arranged to extend along the direction from the first restricted linkage portion 301 to the second restricted linkage portion 401, and the restricting member 5 is inserted into the guiding hole 601.

[0121] With the above structure, through the arrangement of the guiding hole 601, the movement of the restricting member 5 is restricted and guided, making its movement stable, reliable and smooth.

[0122] Further, the door lock includes a first control mounting member 7 for mounting the first control member 3 and a second control mounting member 8 for mounting the second control member 4.

[0123] With the above structure, the arrangements of the first control mounting member 7 and the second control mounting member 8 provide a mounting basis for the mounting of the first control member 3 and the second control member 4.

[0124] Further, the first limiting linkage portion 301 of the first control member 3 is located in the first control mounting member 7, and the first control mounting member 7 is provided with a first mating perforation 701 that matches the first limiting portion 501 for it to enter and cooperate with the first limiting linkage portion 301; the second limiting linkage portion 401 of the second control member 4 is located in the second control mounting member 8, and the second control mounting member 8 is provided with a second mating perforation 801 that matches the second limiting portion 502 for it to enter and cooperate with the second limiting linkage portion 401.

[0125] With the above structure, the structures of the first control mounting member 7 and the second control mounting member 8 are made more reasonable; the setting of the first mating perforation 701 facilitates the mutual cooperation between the first limiting portion 501 and the first limiting linkage portion 301; the setting of the second mating perforation 801 facilitates the mutual cooperation between the second limiting portion 502 and the second limiting linkage portion 401.

[0126] Further, the first control mounting member 7 is provided with a first guiding abutting portion 702, the second control mounting member 8 is provided with a second guiding abutting portion 802, and the distance between the first guiding abutting portion 702 and the second guiding abutting portion 802 matches the length of the guiding member 6, and both ends of the guiding member 6 respectively abut against the first guiding abutting portion 702 and the second guiding abutting portion 802.

[0127] With the above structure, the arrangements of the first guiding abutting portion 702 and the second guiding abutting portion 802 facilitate the installation and fixation of the guiding member 6.

[0128] Further, the first control mounting member 7 is provided with first guiding protrusions 703 protruding on both sides of the first limiting portion 501; the second control mounting member 8 is provided with second guiding protrusions 803 protruding on both sides of the second limiting portion 502.

[0129] With the above structure, the first guiding protrusions 703 can play a guiding role in the movement of the first limiting portion 501, and the second guiding protrusions 803 can play a guiding role in the movement of the second limiting portion 502; the above structure makes the movement of the limiting member 5 more stable and reliable.

[0130] Further, a first limiting linkage fitting chute 704 matching the movement locus of the first limiting linkage part 301 is formed by recessing at a position corresponding to the first limiting linkage part 301 on the first control mounting member 7; a second limiting linkage fitting chute 804 matching the movement locus of the second limiting linkage part 401 is formed by recessing at a position corresponding to the second limiting linkage part 401 on the second control mounting member 8.

[0131] With the above structure, the first limiting linkage fitting chute 704 and the second limiting linkage fitting chute 804 can limit and guide the movement of the first limiting linkage part 301 and the second limiting linkage part 401, making the movement of the first limiting linkage part 301 and the second limiting linkage part 401 smoother and more reliable.

[0132] Further, the first control member 3 includes a first drive shaft 302 for controlling the state of the first lock body 1 and a first operating member 303 provided on the first drive shaft 302 to drive its movement. The first limiting linkage part 301 is provided on the first operating member 303. The first control mounting member 7 is recessed to form a first operating member mounting groove 705 for accommodating and mounting the first operating member 303. The first drive shaft 302 passes through the first operating member mounting groove 705 and is connected to the first lock body 1 to control its state;

[0133] The second control member 4 includes a second drive shaft 402 for controlling the state of the second lock body 2 and a second operating member 403 provided on the second drive shaft 402 to drive its movement. The second limiting linkage part 401 is provided on the second operating member 403. The second control mounting member 8 is recessed to form a second operating member mounting groove 805 for accommodating and mounting the second operating member 403. The second drive shaft 402 passes through the second operating member mounting groove 805 and is connected to the second lock body 2 to control its state.

[0134] With the above structure, the structures of the first control member 3 and the second control member 4 are more reasonable, facilitating user operation and controlling the first lock body 1 and the second lock body 2; the first operating member mounting groove 705 and the second operating member mounting groove 805 can better accommodate the first operating member 303 and the second operating member 403, thereby realizing the installation of the first control member 3 and the second control member 4.

[0135] Further, the first door lock includes a first lock body member 101 and a second lock body member 102. The first lock body member 101 includes a first mating lock portion 1011, and the second lock body member 102 includes a second mating lock portion 1021. One of the first lock body member 101 and the second lock body member 102 is disposed on the first door frame side 100-1, and the other of the first lock body member 101 and the second lock body member 102 is disposed on the first door leaf side 200-1. The first lock body member 101 is movably disposed, and during the movement of the first lock body member 101, there are a first locking position for locking the first mating lock portion 1011 and the second mating lock portion 1021, and a first unlocking position for unlocking the first mating lock portion 1011 and the second mating lock portion 1021. That is, when the first lock body member 101 moves to the first locking position, the first lock body 1 is in the first locked state; when the first lock body member 101 moves to the first unlocking position, the first lock body 1 is in the first unlocked state; the first control member 3 is connected to the first lock body member 101 to drive its movement;

[0136] The second door lock includes a third lock body member 201 and a fourth lock body member 202. The third lock body member 201 includes a third mating lock portion 2011, and the fourth lock body member 202 includes a fourth mating lock portion 2021. One of the third lock body member 201 and the fourth lock body member 202 is disposed on the second door frame side 100-2, and the other of the third lock body member 201 and the fourth lock body member 202 is disposed on the second door leaf side 200-2. The third lock body member 201 is movably disposed, and during the movement of the third lock body member 201, there are a second locking position for locking the third mating lock portion 2011 and the fourth mating lock portion 2021, and a second unlocking position for unlocking the third mating lock portion 2011 and the fourth mating lock portion 2021. That is, when the third lock body member 201 moves to the second locking position, the second lock body 2 is in the second locked state; when the third lock body member 201 moves to the second unlocking position, the second lock body 2 is in the second unlocked state; the second control member 4 is connected to the third lock body member 201 to drive its movement.

[0137] With the above structure, the structures of the first lock body 1 and the second lock body 2 are more reasonable. When the first door frame side 100-1 and the first door body side 200-1 are in the closed state, the first lock body member 101 is located at the first locking position so that the first mating lock portion 1011 is locked and mated with the second mating lock portion 1021 of the second lock body member 102, so as to realize the locking of the first door frame side 100-1 and the first door body side 200-1; when the user operates the first control member 3, the first control member 3 drives the first lock body member 101 to move to the first unlocking position. At this time, the first mating lock portion 1011 and the second mating lock portion 1021 of the second lock body member 102 are unlocked, and the user can separate the first door body side 200-1 and the first door frame side 100-1, that is, the user can open the door body 200 from this side; the second lock body 2 is the same.

[0138] Further, one of the first mating lock portion 1011 and the second mating lock portion 1021 is configured as a first lock post 103; the other of the first door frame 100 locking portion and the first door body 200 locking portion is configured as a first lock hook 104, and the first lock hook 104 is provided with a first card slot 1041 matching the first lock post 103; the first mating lock portion 1011 can approach and move away from the second mating lock portion 1021 along with the movement of the first lock body member 101, and when the first mating lock portion 1011 approaches the second mating lock portion 1021, the first lock post 103 is inserted into the first card slot 1041, and when the first mating lock portion 1011 moves away from the second mating lock portion 1021, the first lock post 103 is separated from the first card slot 1041;

[0139] One of the third mating lock portion 2011 and the fourth mating lock portion 2021 is configured as a second lock post 203; the other of the third door frame 100 locking portion and the fourth door body 200 locking portion is configured as a second through lock hook, and the first lock hook 104 is provided with a first card slot 1041 matching the first lock post 103; the third mating lock portion 2011 can approach and move away from the fourth mating lock portion 2021 along with the movement of the third lock body member 201, and when the third mating lock portion 2011 approaches the fourth mating lock portion 2021, the second lock post 203 is inserted into the second card slot 2041, and when the third mating lock portion 2011 moves away from the fourth mating lock portion 2021, the second lock post 203 is separated from the second card slot 2041.

[0140] Adopting the above structure makes the structures of the first mating lock portion 1011 and the second mating lock portion 1021, as well as the structures of the third mating lock portion 2011 and the fourth mating lock portion 2021 more reasonable and reliable; when the first locking post 103 is inserted into the first card slot 1041, the first mating lock portion 1011 and the second mating lock portion 1021 are locked and mated; when the first locking post 103 disengages from the first card slot 1041, the first mating lock portion 1011 and the second mating lock portion 1021 are unlocked and mated; when the second locking post 203 is inserted into the second card slot 2041, the third mating lock portion 2011 and the fourth mating lock portion 2021 are locked and mated; when the second locking post 203 disengages from the second card slot 2041, the third mating lock portion 2011 and the fourth mating lock portion 2021 are unlocked and mated.

[0141] Further, when the first mating lock portion 1011 is configured as the first locking hook 104, the first lock body member 101 further includes a first locking post chute 105 that matches the first locking post 103 for the first locking post 103 to slide in or out. The first locking hook 104 is disposed on one side of the first locking post chute 105. When the first lock body member 101 moves to the first locking position, the first locking hook 104 enters the first locking post chute 105, and the opening of the first card slot 1041 faces the side wall of the first locking post chute 105. When the first lock body member 101 moves to the first unlocking position, the first locking hook 104 leaves the first locking post chute 105;

[0142] When the third mating lock portion 2011 is configured as the second locking hook 204, the third lock body member 201 further includes a second locking post chute 205 that matches the second locking post 203 for the second locking post 203 to slide in or out. The second locking hook 204 is disposed on one side of the second locking post chute 205. When the third lock body member 201 moves to the second locking position, the second locking hook 204 enters the second locking post chute 205, and the opening of the second card slot 2041 faces the side wall of the second locking post chute 205. When the third lock body member 201 moves to the second unlocking position, the second locking hook 204 leaves the second locking post chute 205.

[0143] With the above structure, when the first doorframe side 100-1 and the first door body side 200-1 are in the closed state, the first locking post 103 enters into the first locking post chute 105, and the first locking hook 104 enters into the first locking post chute 105 to catch the first locking post 103 to achieve locking. And because the opening of the first card slot 1041 faces the side wall of the first locking post chute 105, the first locking post 103 cannot move in the radial direction. At this time, the first locking post 103, the first locking hook 104, and the first locking post chute 105 form a rotating shaft structure to realize the rotation when the door body 200 is opened from the second door body side 200-2; the cooperation of the second locking post 203, the second locking hook 204, and the second locking post chute 205 is the same.

[0144] Specifically, when the first locking body member 101 is arranged on the door body 200, the first locking post chute 105 is formed on the door body 200. When the first locking body member 101 is arranged on the doorframe 100, the first locking post chute 105 is formed on the doorframe 100. When the second locking body member 102 is arranged on the door body 200, the second locking post chute 205 is formed on the door body 200. When the second locking body member 102 is arranged on the doorframe 100, the second locking post chute 205 is formed on the doorframe 100; a first locking body member installation groove 11 for installing and providing its activity space is arranged at the position where the first locking body member 101 is arranged, and a part of the first locking body member installation groove 11 forms the first locking post chute 105. A second locking body member installation groove 12 for installing and providing its activity space is arranged at the position where the second locking body member 102 is arranged, and a part of the second locking body member installation groove 12 forms the second locking post chute 205.

[0145] Further, the first cooperating locking part 1011 can approach or move away from the second cooperating locking part 1021 with the movement of the first locking body member 101 to lock or unlock; the third cooperating locking part 2011 can approach or move away from the fourth cooperating locking part 2021 with the movement of the third locking body member 201 to lock or unlock.

[0146] With the above structure, the structure of the door lock is made more reasonable.

[0147] Further, the first locking body member 101 is rotatably arranged, and the first cooperating locking part 1011 is arranged at a distance from the rotation axis of the first locking body member 101;

[0148] The third locking body member 201 is rotatably arranged, and the third cooperating locking part 2011 is arranged at a distance from the rotation axis of the third locking body member 201.

[0149] With the above structure, it is realized that the first mating lock portion 1011 can approach or move away from the second mating lock portion 1021 as the first lock body member 101 rotates, and the third mating lock portion 2011 can approach or move away from the fourth mating lock portion 2021 as the third lock body member 201 rotates.

[0150] Further, the first control member 3 includes a first drive shaft 302 and a first operating member 303 provided on the first drive shaft 302 to drive the first drive shaft 302 to rotate.

[0151] The second control member 4 includes a second drive shaft 402 and a second operating member 403 provided on the second drive shaft 402 to drive the second drive shaft 402 to rotate. The second drive shaft 402 is connected to the third lock body member 201 in a restricted relative rotation manner, and the axis of the second drive shaft 402 is collinear with the rotation axis of the third lock body member 201.

[0152] With the above structure, the structures of the first control member 3 and the second control member 4 are made more reasonable. When the user operates the first operating member 303 to rotate the first drive shaft 302, the first drive shaft 302 rotates to drive the first lock body member 101 to rotate. Similarly, the second control member 4 drives the second lock body member 102. Specifically, the cross-section of the first drive shaft 302 is non-circular, and a first drive shaft 302 mounting hole that matches the first drive shaft 302 and is used to insert the first drive shaft 302 is provided on the first lock body member 101 to achieve a restricted relative rotation connection between the two. The cross-section of the second drive shaft 402 is non-circular, and a second drive shaft 402 mounting hole that matches the second drive shaft 402 and is used to insert the second drive shaft 402 is provided on the third lock body member 201 to achieve a restricted relative rotation connection between the two. A mating sleeve 13 is sleeved at the positions where the first drive shaft 302 and the second drive shaft 402 pass through the first operating member mounting groove 705 and the second operating member mounting groove 805. The inner hole of the mating sleeve 13 matches the first drive shaft 302 and the second drive shaft 402, and the outer side is a cylindrical arc surface, enabling better rotation of the first drive shaft 302 and the second drive shaft 402. More specifically, the cross-sections of the first drive shaft 302 and the second drive shaft 402 are rectangular. The first operating mounting member 3032 forms a mating sleeve 13 that mates with the first drive shaft 302, and the second operating mounting member 4032 forms a mating sleeve 13 that mates with the second drive shaft 402.

[0153] Furthermore, the first lock body member 101 and the third lock body member 201 are disposed on the door panel. Correspondingly, the first control member 3 and the second control member 4 are disposed on the door panel, and the restricting member 5 is disposed on the door panel.

[0154] With the above structure, the arrangements of the first lock body member 101, the third lock body member 201, the first control member 3 and the second control member 4 are more reasonable and more in line with the user's usage habits.

[0155] Furthermore, the first operating member 303 includes a first operating member body 3031 and a first operating mounting member 3032. The first operating mounting member 3032 is provided with a first driving mounting hole matching the first driving shaft 302. The first operating mounting member 3032 is sleeved on the first driving shaft 302 by relying on the first driving mounting hole and the two are restricted from relative rotation.

[0157] With the above structure, the structures of the first operating member 303 and the second operating member 403 are more reasonable and convenient for actual production and installation. Specifically, the cross sections of the first driving shaft 302 and the second driving shaft 402 are non-circular, and the first driving mounting hole and the second driving mounting hole respectively match the first driving shaft 302 and the second driving shaft 402 to achieve the restricted relative rotation connection therebetween. Specifically, the cross sections of the first driving shaft 302 and the second driving shaft 402 are rectangular.

[0158] Furthermore, the door lock includes a first reset member 9 and a second reset member 10. When the first reset member 9 acts on the first control member 3 and it is not in the first locking control position, it has a tendency to move towards the first locking control position; when the second reset member 10 acts on the second control member 4 and it is not in the second locking control position, it has a tendency to move towards the second locking control position;

[0159] Specifically, the first reset member 9 and the second reset member 10 are elastic members.

[0160] With the above structure, the structure of the door lock is made more reasonable, enabling the first door lock or the second door lock to be automatically locked when the door body 200 and the door panel are closed. Specifically, the first reset member 9 is a torsion spring sleeved on the first drive shaft 302, with both ends respectively abutted between the first operating member and the first operating member mounting groove 705; the second reset member 10 is a torsion spring sleeved on the second drive shaft 402, with both ends respectively abutted between the second operating member and the second operating member mounting groove 805.
