[0041] In the related art, a door lock is generally provided between the body and the door of an electrical device. When the door lock is closed, the sealing and safety of the door on the body can be ensured. When the door needs to be opened, it is generally opened by hand, so it is necessary to design a door handle and other structures on the door. In order to open the door, a handle must be designed, which has a technical problem of affecting the consistency of the appearance and decoration. The embodiment of the present application provides a door lock, which can at least solve the technical problem that the handle designed on the surface of the door affects the appearance to a certain extent.

[0042] Combine the following Figure 1-Figure 13 The present application is described with reference to specific embodiments:

[0043] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a door lock 100 , including a lock body 110 , a lock catch 150 , a movable part 120 , an elastic part 130 and an adjusting part 140 .

[0044] The lock body 110 is provided with a lock opening 113 and a guide groove 114. Figure 3 and Figure 4 A cavity is formed in the lock body 110 , and the lock opening 113 is communicated with the cavity for the lock buckle 150 to extend into.

[0045] For example, reference Figure 1 The lock body 110 may include a shell 111 and a cover 112 . The cover 112 may be covered on the shell 111 and detachably connected to the shell 111 , so that the shell 111 and the cover 112 jointly define a cavity and facilitate the assembly of various components in the lock body 110 .

[0046] The guide groove 114 may be provided inside the lock body 110, or may be provided through the lock body 110. For example, the guide groove 114 may be provided through the housing 111 or the cover 112 along its depth direction, or the guide groove 114 may also be provided on the inner side wall of the housing 111 or the cover 112 to improve the sealing performance of the lock body 110. Figure 2 As shown, a plurality of bosses 1121 are provided on the surface of the cover 112 facing the housing 111 , and the plurality of bosses 1121 together define a guide groove 114 .

[0047] The lock buckle 150 can reciprocate in the lock body 110 through the lock port 113 and can be locked in the lock body 110. Figure 3 and Figure 4The head of the lock buckle 150 can be provided with a buckle portion, and the head of the lock buckle 150 can enter the lock body 110 through the lock port 113 and move back and forth in the lock body 110. For example, when the door body is closed, the head of the lock buckle 150 moves from the lock port 113 to the lock body 110 and can be locked in the lock body 110 to achieve the locking of the door lock 100 and close the door body; when the door body is opened, the lock buckle 150 and the lock body 110 are unlocked, and the head of the lock buckle 150 moves outward from the lock port 113.

[0048] The movable member 120 and the lock buckle 150 are detachably connected, and under the drive of the lock buckle 150, the movable member 120 reciprocates in the lock body 110. In some embodiments, the movable member 120 is movably installed in the lock body 110 and is detachably connected to the lock buckle 150. After the head of the lock buckle 150 enters the lock body 110 from the lock opening 113, the head of the lock buckle 150 can push the movable member 120 to move, thereby driving the movable member 120 to reciprocate in the lock body 110. When the lock buckle 150 is locked in the lock body 110, the lock buckle 150 is connected to the movable member 120, and when the lock buckle 150 is unlocked from the lock body 110, the lock buckle 150 is separated from the movable member 120.

[0049] The elastic member 130 is connected between the lock body 110 and the movable member 120, and applies an elastic force to the movable member 120 toward the lock opening 113. In some embodiments, the elastic member 130 applies an elastic force to the movable member 120 toward the lock catch 150, so that the movable member 120 has a tendency to move toward the direction close to the lock opening 113 to reset. When the lock catch 150 is pressed to move into the lock body 110 and drive the movable member 120, the elastic force of the elastic member 130 needs to be overcome. When the lock catch 150 stops being pressed, the movable member 120 moves in the direction close to the lock opening 113 under the action of the elastic force and pushes the lock catch 150 to exit the lock body 110.

[0050] The adjusting member 140 is rotatably connected to the movable member 120 and is provided with an adjusting portion 143 . The adjusting portion 143 is movable in the guide groove 114 . In some embodiments, the adjusting member 140 is connected to the movable member 120 so that the adjusting member 140 can reciprocate with the movable member 120, and the adjusting member 140 can also rotate relative to the movable member 120. An adjusting portion 143 is provided on the adjusting member 140, and the adjusting portion 143 can move relative to the movable member 120 as the adjusting member 140 rotates. Exemplarily, the adjusting portion 143 can be a columnar structure, so that the adjusting portion 143 can move in the guide groove 114 along the extension direction of the guide groove 114, and drive the adjusting member 140 to reciprocate during the reciprocating movement of the movable member 120 in the lock body 110. Because the adjusting member 140 is rotatably connected to the movable member 120, when the extension direction of the guide groove 114 is different from the moving direction of the movable member 120, the adjusting portion 143 can also move under the guide track of the guide groove 114 and drive the adjusting member 140 to rotate.

[0051] Reference 6 and Figure 7 The guide groove 114 has a restraining position. When the adjusting portion 143 moves to the restraining position, the lock buckle 150 is locked in the lock body 110; when the adjusting portion 143 is disengaged from the guide groove 114, the lock buckle 150 and the lock body 110 are unlocked.

[0052] In some embodiments, the guide groove 114 has a restraining position. When the adjusting portion 143 moves to the restraining position in the guide groove 114, the guide groove 114 can restrain the moving direction of the adjusting portion 143, and transmit the restraint to the movable portion 120 through the adjusting member 140, so that the movable portion 120 is also restrained in the upper limit direction of movement. It can be understood that the restraining direction of the movable portion 120 by the adjusting member 140 is opposite to the direction of the elastic force, so that the movable portion 120 will not move outward under the elastic force of the elastic member 130 when the lock buckle 150 does not apply a driving force to the movable portion 120, thereby locking the lock buckle 150 in the lock body 110. When the adjusting portion 143 is disengaged from the guide groove 114, the adjusting portion 143 is disengaged from the restraining position, so that the restraint of the adjusting portion 143 by the guide groove 114 is released, and the movable portion 120 moves outward under the action of the elastic member 130 and drives the lock buckle 150 to pop out from the lock port 113.

[0053] In actual implementation, Figure 2 As shown, Figure 2The door lock 100 is in the unlocked state, the lock catch 150 can be located outside the lock body 110, and the movable member 120 is in the unlocked position inside the lock body 110. In the process of closing the door body, the head of the lock catch 150 enters the lock body 110 from the lock port 113, and moves inward to drive the movable member 120 to overcome the elastic force of the elastic member 130 and move in the direction away from the lock catch 150. The movable member 120 drives the adjusting member 140 to move during the movement. The adjusting portion 143 provided on the adjusting member 140 can enter the guide groove 114 and move along the guide direction of the guide groove 114, and make the adjusting member 140 rotate relative to the movable member 120. Under the condition that the adjusting portion 143 moves to the restraining position, the guide groove 114 restrains the adjusting portion 143, and then transmits the restraining force to the movable member 120 through the adjusting member 140. The restraining force is opposite to the direction of the elastic force, so that the movable member 120 cannot move in the direction close to the lock port 113. Figure 5 As shown, Figure 5 The movable member 120 of the middle door lock 100 moves to the locked position, the lock catch 150 is locked in the lock body 110, the door lock 100 is locked, and the door body is closed; in the process of opening the door body, the movable member 120 can be driven to move by pushing the lock catch 150 to continue moving, thereby driving the adjustment portion 143 to disengage from the restrained position. Under the condition that the adjustment portion 143 disengages from the guide groove 114, the restraining force of the guide groove 114 on the adjustment portion 143 is released, and the lock catch 150 is released. Under the action of the elastic force of the elastic member 130, the movable member 120 is reset and moved to the unlocked position in the direction close to the lock port 113, and the lock catch 150 abutting therewith is ejected from the lock body 110, thereby completing the unlocking of the door lock 100 and opening the door body under the action of the elastic force.

[0054] According to the door lock 100 provided in the embodiment of the present application, the lock catch 150 moves in the lock body 110 to push the movable member 120 to move, and the movable member 120 drives the adjusting member 140 to move, so that the adjusting portion 143 on the adjusting member 140 moves in the guide groove 114, and under the condition that the adjusting portion 143 moves to the restrained position, the adjusting portion 143 is limited, so that the movable member 120 is also limited, so that the lock catch 150 is locked in the lock body 110; the lock catch 150 pushes the movable member 120 to continue to move so that the adjusting portion 143 disengages from the guide groove 114, the adjusting member 140 is released from the limit, and the movable member 120 moves toward the lock catch 150 under the action of the elastic member 130 and pushes the lock catch 150 to move out of the lock body 110, so that the lock catch 150 and the lock body 110 are unlocked. The lock catch 150 can be locked and unlocked by pressing the lock catch 150 to move back and forth in the lock body 110. Under the action of the elastic member 130, the movable member 120 can directly push the lock catch 150 out of the lock body 110. The door body can be opened without setting a handle. It is convenient to use and more aesthetically pleasing.

[0055] According to some embodiments of the present application, Figure 2-Figure 4 , Figure 7 and Figure 8 As shown, the guide groove 114 may include a restraining section 1141 , the restraining section 1141 may be arranged at an angle to the moving direction of the lock buckle 150 , and the restraining position may be located within the restraining section 1141 .

[0056] In some embodiments, the moving direction of the lock 150 can be consistent with the moving direction of the movable part 120. When the adjusting part 143 moves to the constraint section 1141, the force applied by the side wall of the constraint section 1141 to the adjusting part 143 can form a component in the moving direction of the movable part 120, so that the constraint force on the adjusting part 143 can offset the elastic force applied by the elastic part 130 to the movable part 120, so that the movable part 120 is limited when the adjusting part 143 moves to the constraint position.

[0057] According to some embodiments of the present application, the projection of the restraining section 1141 on the lock body 110 may be concave, the opening of the concave may face away from the lock buckle 150, and the bottom of the concave may be configured as a restraining position.

[0058] In some embodiments, the projection of the constraint section 1141 on the lock body 110 can be in the form of a depression with an opening facing away from the lock buckle 150, so that after the adjustment part 143 enters the constraint section 1141, even if the lock buckle 150 is released, the movable part 120 drives the adjustment part 143 to move in a direction close to the lock buckle 150 under the action of the elastic part 130, and the adjustment part 143 can only slide along the constraint section 1141 to the bottom of the depression, and the bottom of the depression is configured as a constraint position. Under the condition that the adjustment part 143 slides to the bottom of the depression, the constraint effect of the constraint section 1141 on the adjustment part 143 is stable, and the adjustment part 143 is not easy to separate from the constraint section 1141 in the absence of external force, thereby ensuring the stable limiting of the movable part 120 and the locking effect of the lock buckle 150.

[0059] In some embodiments, Figure 2-Figure 4 As shown, the projection of the constraint section 1141 on the lock body 110 can be set in a V-shape: the top angle position of the V-shape is configured as the constraint position. After the adjustment part 143 enters the constraint section 1141, the lock buckle 150 is released, and the adjustment part 143 can slide along the hypotenuse of the constraint section 1141 to the top angle position of the V-shape, thereby achieving the locking of the door lock 100.

[0060] In other embodiments, the projection of the constraint section 1141 on the lock body 110 can be U-shaped or arc-shaped: the U-shaped or arc-shaped bottom is configured as a constraint position, and after the adjustment part 143 enters the constraint section 1141, the lock buckle 150 is released, and the adjustment part 143 can slide along the arc-shaped edge of the constraint section 1141 to the bottom position, thereby locking the door lock 100.

[0061] According to some embodiments of the present application, Figure 1 , Figure 3-Figure 5 As shown, the adjusting member 140 may be connected to the movable member 120 via a rotating shaft 142, the movable member 120 may be provided with a connecting hole 121 for the rotating shaft 142 to pass through, and the elastic member 130 may abut against the rotating shaft 142;

[0062] In some embodiments, a rotating shaft 142 may be provided on the adjusting member 140, and the adjusting member 140 passes through the connecting hole 121 through the rotating shaft 142 so as to be rotatably connected to the movable member 120, and one end of the elastic member 130 may abut against the rotating shaft 142, so that the elastic member 130 simultaneously applies an elastic force to the rotating shaft 142 and the movable member 120 in a direction close to the lock port 113, and the adjusting member 140 may be tightly abutted against the movable member 120.

[0063] refer to Figure 5 A first plane 1421 may be provided on the side of the rotating shaft 142 facing the lock 150, and a second plane 1211 may be provided on the side wall of the connecting hole 121 close to the lock 150. The first plane 1421 may be provided at an angle with the extension direction of the adjusting member 140 to control the rotation direction of the adjusting member 140.

[0064] In some embodiments, a first plane 1421 is provided on the side of the rotating shaft 142 facing the lock 150, and a second plane 1211 is provided on the connecting hole 121 in a direction close to the lock 150. When the movable part 120 is in the unlocked position, the first plane 1421 can be in contact with the second plane 1211. The relative position of the adjusting part 140 and the movable part 120 is the initial relative position. The first plane 1421 is set in the direction of the lock 150, and the second plane 1211 is set in the direction away from the lock 150. The elastic part 130 applies an elastic force to the rotating shaft 142 so that the first plane 1421 has a tendency to keep in contact with the second plane 1211. After the movable member 120 moves and the adjusting member 140 rotates under the action of the adjusting portion 143, the first plane 1421 is inclined along the rotation direction of the adjusting member 140, so that the first plane 1421 and the second plane 1211 are set at an angle, and under the action of the elastic member 130, the angle between the first plane 1421 and the second plane 1211 always tends to fit toward zero degrees, so as to control the adjusting member 140 to always have a tendency to rotate in the direction in which the first plane 1421 and the second plane 1211 fit, that is, the adjusting member 140 always has a tendency to return to the initial relative position, thereby realizing the control of the rotation direction of the adjusting member 140, and then controlling the sliding direction of the adjusting portion 143 in the guide groove 114.

[0065] By setting the first plane 1421 and the extension direction of the adjusting member 140 at an angle, the adjusting member 140 is inclined when the first plane 1421 is in contact with the second plane 1211, and the adjusting portion 143 is offset from the restraining section 1141 in the moving direction of the movable member 120. As a result, after the adjusting portion 143 enters the restraining section 1141 from the inlet end of the restraining section 1141, the adjusting portion 143 always has a movement tendency to separate from the restraining section 1141 toward the outlet end of the restraining section 1141 under the action of the adjusting member 140, so as to control the moving direction of the adjusting portion 143 in the restraining section 1141. During the locking and unlocking process of the door lock 100, the adjusting portion 143 is convenient to move to the restraining position and separate from the restraining position. The structure is simple and the working stability is high.

[0066] According to some embodiments of the present application, Figure 5 As shown, a protrusion 1422 may be provided on the first plane 1421, and a groove 1212 matching the protrusion 1422 may be provided on the second plane 1211. The protrusion 1422 may be provided on the side of the first plane 1421 close to the inlet end of the guide groove 114 for introducing the adjustment portion 143, and the groove 1212 may be provided on the side of the second plane 1211 close to the inlet end of the guide groove 114.

[0067] It can be understood that in order to allow the adjustment part 143 to enter the guide groove 114, during the process of the door lock 100 being unlocked and locked, the adjustment member 140 needs to be rotated toward the entrance end of the guide groove 114 first, so that the side of the first plane 1421 close to the entrance end of the guide groove 114 stops at the second plane 1211, and the side of the first plane 1421 away from the entrance end of the guide groove 114 is tilted.

[0068] In some embodiments, the protrusion 1422 is provided on the side of the first plane 1421 close to the inlet end of the guide groove 114 for introducing the adjustment portion 143, and the groove 1212 is provided on the side of the second plane 1211 close to the inlet end of the guide groove 114. When the movable member 120 is in the unlocked position, the first plane 1421 is fitted with the second plane 1211, and the protrusion 1422 extends into the groove 1212 and is arranged in cooperation with the groove 1212. During the rotation of the adjustment member 140, the protrusion 1422 is provided on the side of the second plane 1211 close to the inlet end of the guide groove 114. The bottom support of 422 and the groove 1212 separates the first plane 1421 from the second plane 1211. The protrusion 1422 is provided to make it easier for the rotating shaft 142 to have a rotation tendency in the opposite direction so that the first plane 1421 and the second plane 1211 are fitted together. The protrusion 1422 and the groove 1212 are provided to limit the rotation angle and the movable range of the rotating shaft 142 during the rotation of the rotating shaft 142, and it can also prevent the rotating shaft 142 from rotating too much and being unable to reset.

[0069] In some embodiments, the end of the protrusion 1422 away from the first plane 1421 can be rounded, and the side wall between the second plane 1211 and the groove 1212 can be rounded to reduce the friction loss between the rotating shaft 142 and the connecting hole 121 during the rotation process, thereby improving the durability of the door lock 100.

[0070] According to some embodiments of the present application, Fig. 9 As shown, a mounting portion 122 may be further provided on the movable member 120 . The mounting portion 122 may extend from the connecting hole 121 to a side of the movable member 120 away from the lock buckle 150 . Part of the elastic member 130 may be provided on the mounting portion 122 .

[0071] In some embodiments, the elastic member 130 is installed by setting a mounting portion 122 to improve the stability of the connection between the elastic member 130 and the movable member 120 and the rotating shaft 142, wherein the mounting portion 122 can extend from the connecting hole 121 to the side of the movable member 120 away from the lock buckle 150, one end of the elastic member 130 extends into the mounting portion 122 and abuts against the rotating shaft 142, and the other end of the elastic member 130 is connected to the inner wall of the lock body 110 away from the lock port 113 to apply an elastic force to the movable member 120 toward the lock port 113.

[0072] Among them, the mounting portion 122 can be a mounting groove or a mounting hole. Taking the mounting portion 122 as a mounting groove as an example, the guide groove 114 is arranged on the inner side of the cover body 112, the adjusting member 140 is arranged between the movable member 120 and the cover body 112, the mounting groove is arranged on the side of the movable member 120 away from the cover body 112, and the side of the movable member 120 close to the cover body 112 is provided with a connecting hole 121 connected to the mounting groove, and the adjusting member 140 is provided with a rotating shaft 142 passing through the connecting hole 121, and at least a part of the elastic member 130 extends into the mounting groove and abuts against the rotating shaft 142.

[0073] It is understandable that the elastic member 130 is installed in compression, so that when the movable member 120 is located in the unlocked position, the elastic member 130 also keeps applying elastic force to the rotating shaft 142 to drive the adjusting member 140 to return to the initial relative position.

[0074] According to the mounting portion 122 and the elastic member 130 provided in the embodiment of the present application, the resetting of the movable member 120 and the resetting of the adjusting member 140 are simultaneously achieved under the condition of providing only one elastic member 130 , and the structural layout is simple, the spatial layout is optimized and the stability is high.

[0075] In the embodiments of the present application, Figure 1 , Figure 3-Figure 5 , Figure 7 and Fig.10As shown, the elastic member 130 may be a spring. In other embodiments, the elastic member 130 may also be a spring sheet, an elastic rubber ring, etc., which is not specifically limited here.

[0076] In other embodiments, the elastic member 130 may include two springs, one of which is connected between the movable member 120 and the lock body 110 to apply an elastic restoring force to the movable member 120 toward the lock port 113; and the other spring is connected between the movable member 120 and the rotating shaft 142 to apply an elastic restoring force to the rotating shaft 142 to drive the adjusting member 140 to rotate.

[0077] According to some embodiments of the present application, Figure 1 , Figure 3-Figure 5 , Figure 7 and Figure 10-13 As shown, the rotating shaft 142 and the adjusting portion 143 are respectively located on two sides of the adjusting member 140 .

[0078] In some embodiments, the adjusting member 140 may include an adjusting rod 141, and the rotating shaft 142 and the adjusting portion 143 may be respectively arranged at both ends of the adjusting rod 141, and the rotating shaft 142 is arranged on the side of the adjusting rod 141 facing the movable member 120, and the adjusting portion 143 is arranged on the side of the adjusting rod 141 facing the guide groove 114.

[0079] The adjusting portion 143 may be cylindrical, one end of the cylinder is connected to the adjusting rod 141 , and the other end extends into the guide groove 114 , so that the adjusting portion 143 can slide in the guide groove 114 , and the structure is simple and easy to assemble.

[0080] In some embodiments, the adjustment portion 143 may be rotatably mounted on the adjustment rod 141 to further reduce frictional resistance and reduce wear during use.

[0081] According to some embodiments of the present application, Figure 2-Figure 4 As shown, the guide groove 114 may further include an inlet section 1142 and an outlet section 1143 , wherein the inlet section 1142 and the outlet section 1143 are respectively connected to two sides of the restraining section 1141 and are both extended along the moving direction of the lock buckle 150 .

[0082] In some embodiments, the inlet section 1142, the constraint section 1141 and the outlet section 1143 are sequentially distributed along the rotation direction of the adjustment member 140, referring to Figure 6 , Figure 6 The moving track of the adjusting portion 143 when the movable member 120 moves from the unlocking position to the locking position, the adjusting portion 143 first enters the inlet section 1142, and then transitions from the inlet section 1142 to the restraining section 1141; Figure 8 , Figure 8When the movable member 120 moves from the locked position to the unlocked position, the adjusting portion 143 transitions from the restraining section 1141 to the outlet section 1143 and returns to the initial relative position. Figure 3 When the adjusting portion 143 is located at the initial relative position, the adjusting portion 143 is located between the restraining section 1141 and the outlet section 1143 in the rotation direction of the adjusting member 140, so that the adjusting portion 143 can move along the trajectory of the inlet section 1142-restraining section 1141-outlet section 1143 under the action of the elastic member 130.

[0083] The inlet section 1142 and the outlet section 1143 both extend along the moving direction of the lock buckle 150. By setting the inlet section 1142 and the outlet section 1143, the movable range of the adjustment part 143 can be limited, and then the rotation angle range of the adjustment member 140 can be limited, thereby avoiding the difficulty in resetting the adjustment member 140 due to excessive rotation angle of the adjustment member 140, thereby improving the working stability of the door lock 100.

[0084] According to some embodiments of the present application, Figure 2-Figure 4 and Figure 7 As shown, a guide portion 115 may be connected between the inlet section 1142 and the outlet section 1143 , and the guide portion 115 may extend from the outlet end of the outlet section 1143 to the outlet end of the inlet section 1142 .

[0085] In some embodiments, in conjunction with reference Figure 6 and Figure 8 After the adjusting part 143 slides out from the outlet end of the outlet section 1143, the movable part 120 can move to the unlocking position, and the adjusting part 143 can move to the initial relative position under the action of the elastic part 130. When the door lock 100 is locked next time, because the adjusting part 143 is located between the outlet section 1143 and the restraining section 1141 in the rotation direction of the adjusting part 140, the adjusting part 143 needs to be introduced into the outlet section 1143 first. By providing the guide part 115, when the lock buckle 150 pushes the movable part 120 to move in the direction away from the lock port 113, the adjusting part 143 slides from the outlet section 1143 to the inlet section 1142 under the guidance of the guide part 115.

[0086] It can be understood that the outlet end of the inlet section 1142 is the inlet end of the restriction section 1141 .

[0087] In some embodiments, Figure 2-Figure 4As shown, the guide groove 114 is defined by a plurality of bosses 1121 provided on the inner side surface of the cover body 112, wherein a guiding slope is formed on the side of the boss 1121 facing the adjusting portion 143 in the moving direction of the lock buckle 150 toward the lock port 113, and the guiding slope is inclined from the outlet section 1143 to the inlet section 1142 in a direction away from the lock port 113, so that after the adjusting portion 143 abuts against the guiding slope, the guiding slope can guide the adjusting portion 143 to move and cause the adjusting member 140 to rotate in a direction close to the inlet section 1142.

[0088] In other embodiments, the guide portion 115 may be a guide groove, which may be inclined from the outlet section 1143 to the inlet section 1142 along a direction away from the lock port 113. When the adjustment portion 143 starts to move from the initial relative position, it first enters the guide groove and moves toward the inlet section 1142 under the guidance of the guide groove. Furthermore, the two ends of the guide groove may be respectively connected to the outlet section 1143 and the inlet section 1142, so that the guide groove 114 and the guide groove are connected as a closed whole, and the adjustment portion always moves in the guide groove or the guide groove 114.

[0089] According to some embodiments of the present application, Figure 2-Figure 4 As shown, the guide groove 114 can also include a guide groove section 1144, which can be connected between the outlet section 1143 and the constraint section 1141. The guide groove section 1144 and the constraint section 1141 can be connected at an angle, and the opening of the angle formed by the guide groove section 1144 and the constraint section 1141 can be set toward the lock mouth 113.

[0090] In some embodiments, the outlet slot 1144 can be connected between the outlet section 1143 and the constraint section 1141, so that the adjustment part 143 first enters the outlet slot 1144 after sliding out of the constraint section 1141. By setting the opening of the included angle between the outlet slot 1144 and the constraint section 1141 toward the lock port 113, on the one hand, the corner of the outlet slot 1144 and the constraint section 1141 can limit the adjustment part 143 to prevent the adjustment part 143 from exceeding the range of motion, and on the other hand, the adjustment part 143 can be locked. When the adjusting portion 143 is in the initial relative position, the adjusting portion 143 and the lead-out groove 1144 are directly opposite to each other in the moving direction of the lock buckle 150, so that when the lock buckle 150 pushes the movable member 120 to move in the direction away from the lock port 113, the adjusting portion 143 always has a tendency to move to the lead-out groove 1144. When the lock buckle 150 is released under the condition that the adjusting portion 143 is located in the lead-out groove 1144, the movable member 120 can always move to the unlocking position under the action of the elastic member 130, and the working stability of the door lock 100 is higher.

[0091] According to some embodiments of the present application, Figure 3 , Figure 4 and Figure 7As shown, the lock buckle 150 , the movable member 120 and the guide groove 114 are sequentially arranged along the moving direction of the lock buckle 150 .

[0092] In some embodiments, the lock buckle 150, the movable part 120 and the guide groove 114 are arranged in sequence, and the guide groove 114 is arranged on the side of the movable part 120 away from the lock buckle 150, so that the guide groove 114 can limit the adjustment part, the structural layout is simple and the working process is more stable.

[0093] According to some embodiments of the present application, Figure 10-13 As shown, the door lock 100 may further include a driving member 160 , which is installed in the lock body 110 , and is used to drive the movable member 120 to move along the movable direction of the lock buckle 150 .

[0094] In some embodiments, by setting a driving member 160 in the lock body 110, the driving member 160 can drive the movable member 120 to move along the moving direction of the lock buckle 150, wherein the driving member 160 can be a component that can be automatically controlled or remotely controlled. When the door lock 100 is in a locked state, the movable member 120 is in a locked position, and the lock buckle 150 can be driven to move without manual driving. By controlling the driving member 160 to drive the movable member 120 to move in a direction away from the lock port 113, and making the adjustment part slide out of the guide groove 114, the door lock 100 and the door body can be automatically opened. In conjunction with the program setting of the electrical equipment, in the equipment that needs to be cleaned with water, the driving member 160 can be controlled to automatically open the door body after the cleaning is completed, so as to accelerate the evaporation of water vapor in the equipment; or, an opening button can be set on the electrical equipment, and an opening instruction can be set on the terminal, and an instruction can be sent to the driving member 160 by operating the opening button or the opening instruction to realize the automatic opening of the door body.

[0095] According to some embodiments of the present application, Figure 10-13 As shown, one end of the movable member 120 away from the lock opening 113 may be provided with a baffle 124 extending laterally, and the output end of the driving member 160 may be connected to the baffle 124 .

[0096] In some embodiments, the movable part 120 may be provided with a baffle 124 extending laterally, and the driving part 160 may be arranged on the side of the movable part 120 where the baffle 124 is provided. By connecting the output end of the driving part 160 with the baffle 124, the movable part 120 can be driven to move without interfering with the normal arrangement of structures such as the movable part 120 and the elastic part 130.

[0097] Exemplarily, the output end of the driving member 160 is provided with a driving rod 161 which can move along the moving direction of the lock 150, and the driving rod 161 pushes the baffle 124 to move and then drives the movable member 120 to move, wherein the driving member 160 can be an electric support rod, a cylinder, an electromagnetic push rod, etc., and is not specifically limited.

[0098] According to some embodiments of the present application, Figure 1 , Figure 3-Figure 5 , Figure 7 and Figure 10-13 As shown, the door lock 100 may further include two hooks 123 , which are rotatably connected to the movable member 120 . The two hooks 123 are openable and closable, and the head of the lock buckle 150 may be locked by the two hooks 123 .

[0099] In some embodiments, the two hooks 123 are respectively arranged on both sides of the movable part 120, and are respectively rotatably connected to the side of the movable part 120 facing the lock mouth 113. The two hooks 123 can be opened and closed. When the lock buckle 150 pushes the movable part 120 to move to the locked position, the two hooks 123 close inward to lock the head of the lock buckle 150, thereby locking the door lock 100; when the movable part 120 moves toward the lock mouth 113 until it is unlocked under the elastic force of the elastic part 130, the two hooks 123 open outward to unlock the head of the lock buckle 150, so that the movable part 120 can directly push the lock buckle 150 out of the lock body 110, thereby unlocking the door lock 100.

[0100] According to some embodiments of the present application, Figure 1 , Figure 3-Figure 5 , Figure 7 and Figure 10-13 As shown, the lock body 110 can also be provided with a through opening 116 for the lock buckle 150 to reciprocate. The through opening 116 can include an expansion section 1161 and a guide section 1162 that are sequentially arranged toward the interior of the lock body 110. The movable part 120 can reciprocate in the guide section 1162. The width dimension of the expansion section 1161 can be sequentially expanded in a direction close to the lock opening 113. The two hooks 123 can be rotated to the side wall of the expansion section 1161 to unlock the lock buckle 150 and the two hooks 123.

[0101] In some embodiments, the two hooks 123 are subjected to an elastic force in a direction away from each other. For example, a torsion spring may be provided between the hook 123 and the movable member 120 .

[0102] A through opening 116 for the reciprocating movement of the lock buckle 150 and the movable part 120 may be provided in the lock body 110, and the through opening 116 may be connected to the lock port 113, wherein the through opening 116 includes an expansion section 1161 and a guide section 1162 arranged in sequence, the expansion section 1161 is connected to the lock port 113, and the width dimension of the expansion section 1161 can be expanded in sequence in a direction close to the lock port 113 to form a trumpet shape. In one example, the maximum width of the expansion section 1161 is the same as the width of the lock port 113, and the minimum width of the expansion section 1161 is the same as the width of the guide section 1162.

[0103] When the movable member 120 is in the unlocking position, the two hooks 123 are separated from each other by the elastic force and rotated to contact the side wall of the expansion section 1161 in the width direction, so that the hooks 123 unlock the head of the lock catch 150; when the movable member 120 moves to the locking position, because the width of the expansion section 1161 is reduced in the direction away from the lock opening 113, the side wall of the opening 116 pushes the two hooks 123 to close inward and locks the head of the lock catch 150. The structure is simple and the locking effect is stable, ensuring the stability of the door lock 100.

[0104] Based on the same utility model concept, an embodiment of the present application also provides an electrical device, which includes a body, a door body, and a door lock 100, a lock buckle 150 and a lock body 110 as in any of the above technical solutions, one of which is connected to the door body and the other is connected to the body.

[0106] In some embodiments, the door lock 100 can be locked and unlocked by pressing the door body or pressing a button on the door body to drive the lock buckle 150 to move inside the lock body 110. When unlocking, the lock buckle 150 is ejected out of the lock body 110 under the action of the elastic member 130, thereby enabling the door body of the electrical equipment to open automatically without the need for a door handle.

[0107] According to the electrical device provided in the embodiment of the present application, the lock buckle 150 moves in the lock body 110 to push the movable part 120 to move, and the movable part 120 drives the adjusting part 140 to move, so that the adjusting portion 143 on the adjusting part 140 moves in the guide groove 114, and under the condition that the adjusting portion 143 moves to the constrained position, the adjusting portion 143 is limited, so that the movable part 120 is also limited, so that the lock buckle 150 is locked in the lock body 110; the lock buckle 150 pushes the movable part 120 to continue to move so that the adjusting portion 143 disengages from the guide groove 114, the adjusting part 140 is released from the limit, and the movable part 120 moves toward the lock buckle 150 under the action of the elastic part 130 and pushes the lock buckle 150 to move out of the lock body 110, so that the lock buckle 150 and the lock body 110 are unlocked. The locking and unlocking of the lock buckle 150 can be achieved by pressing the door body to drive the lock buckle 150 to move back and forth in the lock body 110, and under the action of the elastic member 130, the movable member 120 can directly push the lock buckle 150 out of the lock body 110, so that the door body can be opened without setting a handle, which is convenient to use and more aesthetically pleasing.
