A door lock, cabinet and automated device

Abstract

The application discloses a door lock, a cabinet and an automatic device. When the door lock is closed, an external force is used to drive a door plate to be close to a door frame. At this time, the external force is used to drive a transmission shaft to move in a direction close to a second locking piece, so that the transmission shaft extends into a through groove, an elastic piece is compressed, a blocking shaft is in contact with a guide block, and the blocking shaft moves along the guide block and can move to the bottom surface of the guide block. When the blocking shaft moves, the blocking shaft can drive the guide block to rotate and drive the second locking piece to rotate, so that a first meshing part and a second meshing part are engaged and locked, thereby realizing locking between the first locking piece and the second locking piece. Since the blocking shaft is located on the bottom surface of the guide block, when the external force disappears, the blocking shaft is in contact with the bottom surface of the guide block under the action of the elastic piece, thereby realizing that the first locking piece and the second locking piece are kept locked, and thereby realizing locking. The application can reduce the occupied space and can be suitable for the scene that a part of the door plate is in contact with the door frame.

Description

Technical Field

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

[0002] Door locks in related technologies typically include a base and a baffle. The baffle is installed on the door frame, and the base is installed on the door panel. The base is equipped with a bolt and a handle. By rotating the handle, the bolt is moved so that it rests against or moves away from the baffle, thereby achieving locking and unlocking.

[0003] The door locks in the related technologies require a large space, and the door frame needs to reserve space for the bolt to rotate. Furthermore, the door locks in the related technologies are not suitable for scenarios where part of the door panel is against the door frame. Summary of the Invention

[0004] This application aims to solve at least one of the technical problems existing in the prior art. To this end, this application proposes a door lock, cabinet, and automated equipment that eliminates the need to reserve space for the bolt to rotate on the door frame, thereby reducing space occupation and making it applicable to scenarios where part of the door panel abuts against the door frame.

[0005] The door lock according to the first aspect of this application includes:

[0006] The base is used for installation on the door frame, and the base is provided with a first mounting groove;

[0007] A first locking member is movably installed in the first mounting slot, and the first locking member is located at the bottom of the first mounting slot.

[0008] The second locking member is movably installed in the first mounting slot. The first locking member has a first engaging part at one end near the second locking member, and the second locking member has a second engaging part at one end near the first locking member. The second locking member has a through groove, and the inner sidewall of the through groove has at least two spaced guide blocks.

[0009] A limiting structure is provided on the side wall of the first mounting groove, and the limiting structure abuts against the second locking member;

[0010] Mounting housing, the mounting housing being used for mounting on a door panel;

[0011] A drive shaft, which is movably mounted to the mounting housing;

[0012] An elastic element is sleeved on the drive shaft, and the elastic element is used to apply a spring force to the drive shaft in a direction away from the second locking element when it is in a compressed state;

[0013] A stop shaft is inserted at one end of the drive shaft near the second locking member. When the drive shaft moves in the direction near the second locking member under the action of an external force, the drive shaft extends into the through groove, causing the elastic member to contract and the stop shaft to contact the guide block. The stop shaft then moves to the bottom surface of the guide block. When the stop shaft moves, it can drive the guide block to rotate the second locking member, so that the first engaging part engages and locks with the second engaging part. When the external force disappears, under the action of the elastic member, the stop shaft abuts against the bottom surface of the guide block.

[0014] The bottom surface of the guide block is the side of the guide block that is away from the mounting shell.

[0015] The door lock according to the embodiments of this application has at least the following beneficial effects: The door lock of the embodiments of this application is applicable to scenarios where a part of the door panel abuts against the door frame when the door is closed. When the door is closed, the door panel is driven closer to the door frame by an external force, so that the mounting shell can move in the direction closer to the base. At this time, the transmission shaft is driven to move in the direction closer to the second locking member by an external force, so that the transmission shaft extends into the through groove, causing the elastic member to compress and the stop shaft to contact the guide block. During the movement of the stop shaft, the stop shaft can move along the guide block to the bottom surface of the guide block. When the stop shaft moves, it can drive the guide block to rotate the second locking member, so that the first engaging part and the second engaging part engage and lock. Since the stop shaft is located on the bottom surface of the guide block, when the external force disappears, the stop shaft abuts against the bottom surface of the guide block under the action of the elastic member, thereby achieving the locking between the first locking member and the second locking member. Therefore, the stop shaft and the second locking member remain relatively fixed, thereby making the mounting shell and the base relatively fixed, that is, the door panel and the door frame relatively fixed, thereby achieving locking. Furthermore, during this process, the limiting structure prevents the second locking member from disengaging from the base. When the door needs to be opened, an external force drives the door panel away from the door frame. At this time, the mounting shell moves away from the base, which drives the transmission shaft to move away from the second locking member. This causes the stop shaft to move along the guide block until it separates from the guide block. When the stop shaft moves, it drives the guide block to rotate the second locking member, causing the first engaging part to disengage from the second engaging part. This allows the stop shaft and transmission shaft to move away from the base along with the mounting shell, thereby unlocking the door. During this process, the limiting structure prevents the second locking member from disengaging from the base. Therefore, the door lock of this embodiment does not require space to be reserved on the door frame for the bolt to rotate, which can reduce the space occupied and is applicable to scenarios where part of the door panel abuts against the door frame.

[0017] The bottom surface of the guide block is provided with a second guide surface, which is used to guide the stop shaft so that the stop shaft can move to separate from the bottom surface of the guide block.

[0019] According to some embodiments of this application, the first engaging portion is provided with a plurality of arc-shaped recesses, and the plurality of arc-shaped recesses are arranged along the circumference of the first locking member;

[0020] The second engaging portion is provided with a plurality of arc-shaped protrusions that match the arc-shaped concave portion, and the arc-shaped protrusions are arranged along the circumference of the second locking member.

[0047] Reference Figures 1 to 8 The first aspect of this application provides a door lock. Figure 1 This is a schematic diagram of the structure of a door lock according to an embodiment of this application. The door lock according to an embodiment of this application includes:

[0048] The base 100 is used for installation on the door frame 400, and the base 100 is provided with a first mounting groove 104;

[0049] The first locking member 110 is movably installed in the first mounting groove 104, and the first locking member 110 is located at the bottom of the first mounting groove 104.

[0050] The second locking member 120 is movably installed in the first mounting groove 104. The first locking member 110 has a first engaging part 111 at one end near the second locking member 120, and the second locking member 120 has a second engaging part 122 at one end near the first locking member 110. The second locking member 120 has a through groove, and the inner sidewall of the through groove has at least two spaced guide blocks 121.

[0051] The limiting structure 105 is provided on the side wall of the first mounting groove 104 and abuts against the second locking member 120.

[0052] Mounting housing 200 is used for mounting on door panel 300;

[0053] Drive shaft 220 is movably mounted on mounting housing 200;

[0054] The elastic element 240 is sleeved on the drive shaft 220. The elastic element 240 is used to apply a spring force to the drive shaft 220 in a direction away from the second locking element 120 when it is in a compressed state.

[0055] A stop shaft 230 is inserted through the end of the drive shaft 220 near the second locking member 120. When the drive shaft 220 is under the action of an external force, it moves in the direction close to the second locking member 120. The drive shaft 220 extends into the through groove, causing the elastic member 240 to contract and the stop shaft 230 to contact the guide block 121. The stop shaft 230 moves to the bottom surface of the guide block 121. When the stop shaft 230 moves, it can drive the guide block 121 to rotate the second locking member 120, so that the first engaging part 111 and the second engaging part 122 engage and lock. When the external force disappears, under the action of the elastic member 240, the stop shaft 230 abuts against the bottom surface of the guide block 121.

[0056] The bottom surface of the guide block 121 is the side of the guide block 121 that is away from the mounting shell 200.

[0057] Reference Figure 2 , Figure 2 This is a schematic diagram illustrating the application of a door lock according to an embodiment of this application. The door lock of this embodiment can be used in scenarios where, when the door is closed, a portion of the door panel 300 abuts against the door frame 400. The mounting housing 200 is mounted on the door panel 300, while the base 100 is mounted on the door frame 400. (Refer to...) Figures 3 to 5The door lock of this application embodiment is applicable to scenarios where a portion of the door panel 300 abuts against the door frame 400 when the door is closed. When the door is closed, an external force drives the door panel 300 closer to the door frame 400, enabling the mounting housing 200 to move in a direction close to the base 100. At this time, an external force drives the transmission shaft 220 to move in a direction close to the second locking member 120, causing the transmission shaft 220 to compress the elastic member 240 and extend into the through groove, so that the stop shaft 230 contacts the guide block 121. During the movement of the stop shaft 230, the stop shaft 230 can move along the guide block 121 to the bottom surface of the guide block 121. During movement, the guide block 121 can drive the second locking member 120 to rotate, causing the first engaging part 111 and the second engaging part 122 to engage and lock, thereby achieving locking between the first locking member 110 and the second locking member 120. Since the stop shaft 230 is located on the bottom surface of the guide block 121, when the external force disappears, under the action of the elastic member 240, the stop shaft 230 abuts against the bottom surface of the guide block 121, thus keeping the stop shaft 230 and the second locking member 120 relatively fixed, thereby keeping the mounting shell 200 and the base 100 relatively fixed, that is, keeping the door panel 300 and the door frame 400 relatively fixed, thereby achieving locking. Furthermore, during this process, the limiting structure 105 can prevent the second locking member 220 from disengaging from the base. When the door needs to be opened, the door panel 300 is driven away from the door frame 400 by external force. At this time, the mounting shell 200 moves away from the base 100, which can drive the transmission shaft 220 to move away from the second locking member 120. This causes the stop shaft 230 to move along the guide block 121 until it separates from the guide block 121. When the stop shaft 230 moves, it can drive the guide block 121 to rotate the second locking member 120, so that the first engaging part 111 and the second engaging part 122 are disengaged. This allows the stop shaft 230 and the transmission shaft 220 to move away from the base 100 along with the mounting shell 200, thereby unlocking the door. During this process, the limiting structure 105 can prevent the second locking member 220 from disengaging from the base. Therefore, the door lock of this embodiment does not need to reserve space for the bolt to rotate on the door frame 400, which can reduce the space occupied and is applicable to scenarios where part of the door panel 300 abuts against the door frame 400.

[0058] It should be noted that the limiting structure 105 is used to restrict the second locking member 220. The limiting structure 105 is located on the side wall of the first mounting groove 104, and the second locking member 220 and the first locking member are located between the limiting structure 105 and the bottom of the first mounting groove 104. The limiting structure 105 abuts against the second locking member 220, which can prevent the second locking member 220 from disengaging from the base 100. The limiting structure 105 can be a protrusion, a limiting groove, or a structure with a limiting function. Furthermore, the limiting structure 105 does not restrict the movement of the stop shaft 230.

[0059] In one embodiment, the limiting structure 105 is a limiting protrusion, which is easy to process.

[0060] Understandably, referring to Figure 6 and 7 , Figure 6 This is a schematic diagram of the structure of the second locking member 120 according to an embodiment of this application. Figure 7 This is a structural schematic diagram of the second locking member 120 from another angle according to an embodiment of this application. The end face of the guide block 121 is provided with a first guide surface; the first guide surface is used to guide the stop shaft 230 so that the stop shaft 230 can move to the bottom surface of the guide block 121; the bottom surface of the guide block 121 is provided with a second guide surface, which is used to guide the stop shaft 230 so that the stop shaft 230 can move to separate from the bottom surface of the guide block 121.

[0061] Specifically, there are two guide blocks 121, spaced apart, with the gap between them allowing the drive shaft 220 and the stop shaft 230 to pass through. Each guide block 121 has two first guide surfaces on its end face, which are inclined in the direction close to the first locking member 110. When locking, the stop shaft 230 moves in the direction close to the first locking member 110, with one end of the stop shaft 230 abutting against one of the first guide surfaces. The first guide surfaces guide the stop shaft 230 so that it can move to the bottom of the guide block 121. During this process, the stop shaft 230 drives the guide block 121 to rotate the second locking member 120, causing the first engaging part 111 to engage and lock with the second engaging part 122. During unlocking, the stop shaft 230 moves away from the first locking member 110, abuts against the second guide surface, and the second guide surface guides the stop shaft 230 so that the stop shaft 230 drives the guide block 121 to rotate the second locking member 120 during the movement, thereby disengaging the first engaging part 111 from the second engaging part 122 and separating the stop shaft 230 from the bottom surface of the guide block 121.

[0062] It is understood that the first mounting groove 104 is cylindrical in shape; the first locking member 110 and the second locking member 120 are also cylindrical in shape. Since the first mounting groove 104, the first locking member 110, and the second locking member 120 are all cylindrical, the first locking member 110 and the second locking member 120 can rotate within the first mounting groove 104. This allows the stop shaft 230 to drive the second locking member 120 to rotate during movement, thereby causing relative rotation between the first locking member 110 and the second locking member 120, resulting in either engagement or disengagement of the first engaging portion 111 and the second engaging portion 122.

[0063] It should be noted that in one embodiment, the mounting shell 200 is also cylindrical in shape, and the size of the mounting shell 200 is smaller than the size of the first mounting groove 104. When locked, the door panel 300 is driven to approach the door frame 400 by external force, so that the mounting shell 200 can move in the direction close to the base 100. At this time, a part of the mounting shell 200 extends into the first mounting groove 104.

[0064] It is understood that the first engaging part 111 has multiple arc-shaped recesses, which are arranged circumferentially along the first locking member 110; the second engaging part 122 has multiple arc-shaped protrusions that match the arc-shaped recesses, which are arranged circumferentially along the second locking member 120. Each arc-shaped recess corresponds one-to-one with a corresponding arc-shaped protrusion, enabling the first engaging part 111 and the second engaging part 122 to engage and connect. It should be noted that in related technologies, the structures used for engagement are all sharp-angled, while in this application, the portion of the arc-shaped protrusion facing the arc-shaped recess is flat, and correspondingly, the portion of the arc-shaped recess facing the arc-shaped protrusion is also flat. Compared with related technologies, the arc-shaped protrusions and recesses in this application reduce the required precision of engagement, make engagement more stable, and reduce production costs.

[0065] Understandably, the mounting housing 200 is provided with a second mounting groove 203, and the bottom of the second mounting groove 203 is provided with a first through hole, through which the drive shaft 220 is movably inserted. One end of the drive shaft 220 is located inside the second mounting groove 203, and the other end is located outside the second mounting groove 203. A stop shaft 230 is inserted through the other end of the drive shaft 220, so that the stop shaft 230 is located outside the second mounting groove 203. During the movement of the drive shaft 220, the second mounting groove 203 and the first through hole can guide the drive shaft 220, making the movement of the drive shaft 220 more stable.

[0066] Understandably, referring to Figures 3 to 5 The door lock in this embodiment also includes a pressing part 210, which is movably mounted in the second mounting groove 203. The pressing part 210 is fixedly connected to the drive shaft 220. The pressing part 210 is used to drive the drive shaft 220 to move in a direction closer to or away from the second locking member 120 under the action of external force. During the movement of the pressing part 210, the drive shaft 220 can be driven to move, making it convenient for the user to control the movement of the drive shaft 220 through the pressing part 210, thus making it more convenient to use.

[0067] It is understood that the elastic element 240 is located in the second mounting groove 203 and is sleeved on the drive shaft 220. In one embodiment, the elastic element 240 is a spring.

[0068] Specifically, the elastic element 240 is sleeved on the drive shaft 220, with one end of the elastic element 240 abutting against the groove wall of the second mounting groove 203 and the other end abutting against the pressing part 210. When locking, external force drives the pressing part 210, causing it to move the drive shaft 220 in a direction close to the second locking member 120. This causes the end of the drive shaft 220 away from the mounting housing 200 to extend into the through groove, bringing the stop shaft 230 into contact with the guide block 121. During the movement of the stop shaft 230, it moves along the guide block 121 to the bottom surface of the guide block 121. The movement of the stop shaft 230 drives the guide block 121 to rotate the second locking member 120, causing the first engaging part 111 to engage with the second locking member 120. The engaging part 122 engages and locks, thereby locking the first locking member 110 and the second locking member 120. Since the stop shaft 230 is located on the bottom surface of the guide block 121 and the elastic member 240 is in a compressed state, it can apply a spring force to the drive shaft 220 in a direction away from the second locking member 120, so that the stop shaft 230 and the bottom surface of the guide block 121 remain abutted. Therefore, the stop shaft 230 and the second locking member 120 remain relatively fixed, thereby keeping the mounting shell 200 and the base 100 relatively fixed, thus achieving locking. When unlocking is required, the pressing part 210 is driven by external force to move the transmission shaft 220 away from the second locking member 120. At this time, the elastic member 240 recovers and can apply elastic force to the pressing part 210, so that the pressing part 210 can move away from the second locking member 120. This allows the pressing part 210 to drive the transmission shaft 220, thereby driving the stop shaft 230 to move along the guide block 121 until it separates from the guide block 121. When the stop shaft 230 moves, it can drive the guide block 121 to rotate the second locking member 120, so that the first engaging part 111 and the second engaging part 122 are disengaged, allowing the stop shaft 230 and the transmission shaft 220 to move away from the base 100 along with the mounting shell 200, thereby achieving unlocking.

[0069] In one embodiment, the pressing part 210 is provided with a guide groove, the opening of which is opposite to the first through hole. One end of the drive shaft 220 is fixed to the bottom of the guide groove, and a spring is sleeved on the drive shaft 220. One end of the spring abuts against the bottom of the second mounting groove 203, and the other end abuts against the bottom of the guide groove. The guide groove serves to guide the drive shaft 220.

[0070] Understandably, referring to Figure 1 and Figure 2The base 100 has a first retaining ring 103 on its outer side wall and a thread on its outer side wall. A nut 101 is fitted onto the thread. The nut 101 can move outward from the base 100. When installing the base 100, the base 100 passes through the door frame 400, and the door frame 400 is positioned between the nut 101 and the first retaining ring 103. The nut 101 and the first retaining ring 103 lock the door frame 400, thereby fixing the base 100 to the door frame 400.

[0071] It is understood that the door lock in this embodiment of the application also includes a washer 102, which is sleeved on the outer side wall of the base 100 and located between the first retaining ring 103 and the nut 101. The nut 101 abuts against the door frame 400 through the washer 102, so that the nut 101 can lock the door frame 400 and also prevent the nut 101 from directly contacting the door frame 400.

[0072] It is understood that the outer wall of the mounting housing 200 is provided with a second retaining ring 201 and a third retaining ring 202, which are spaced apart and are used to engage the door panel 300. The door panel 300 is positioned between the second retaining ring 201 and the third retaining ring 202, and the mounting housing 200 is thus installed on the door panel 300 by the engagement of the second retaining ring 201 and the third retaining ring 202.
