[0053] Now, the accompanying drawings will be referred to in describing the exemplary embodiments according to the present utility model. Figures 1 to 3 The exemplary embodiments according to the present utility model will be described in more detail.
[0054] As shown in Figure 1 and Figure 2 The present utility model provides a door lock structure 100 of a container 200 for locking and releasing between a door body 210 and a door frame 220 of the container 200. The door lock structure 100 comprises a locking assembly 10 and an electric driving assembly. The locking assembly 10 is used to prevent the pivoting opening of the door body 210, and the electric driving assembly is used to convert the state of the locking assembly 10.
[0055] The locking assembly 10 comprises a lock rod 11, a lock seat 12 and a lock head 13. The lock rod 11 is fixedly connected to the door body 210 of the container 200, and the lock seat 12 is fixedly connected to the door frame 220 of the container 200. The lock seat 12 has a lock hole. The lock hole can be a through hole or a non-through hole. At least one end of the lock rod 11 is a hollow structure, and at least part of the lock head 13 is sleeved in the hollow structure. The lock head 13 comprises a first end located in the hollow structure and a second end opposite to the first end. The lock head 13 can move along the axial direction of the lock rod 11 to the second end to extend into the lock hole or to be separated from the lock hole. Thus, when the lock head 13 extends into the lock seat 12, the door lock structure 100 is in a locked state, preventing the pivoting opening of the door body 210; when the lock head 13 is separated from the lock seat 12, the door lock structure 100 is in an unlocked state, and the door body 210 can be pivoted to open.
[0056] The electric driving assembly comprises an operating switch 21 connected in series in the control circuit of the electric driving assembly. The operating switch 21 has an on state and an off state. In the on state of the operating switch 21, the control circuit of the electric driving assembly is turned on, and in the off state of the operating switch 21, the control circuit of the electric driving assembly is turned off. The state conversion of the operating switch 21 can be operated by personnel, for example, the operating switch 21 is set as a button switch. The electric driving assembly is used to drive the lock head 13 to move along the axial direction of the lock rod 11 in the on state of the operating switch 21, for example, to drive the lock head 13 to move close to or away from the lock seat 12. The electric driving assembly is, for example, an electric telescopic rod or an electromagnetic driving member, etc. which can drive the lock head 13 to move linearly, and is preferably an electromagnetic driving member.
[0057] The door lock structure 100 of the present solution adopts a telescopic door lock structure 100. A person controls the on-off of the circuit by operating the switch 21. In the on state of the circuit, the lock head 13 can be driven to move, that is, to switch between the locked state and the unlocked state. Therefore, the door lock structure 100 of the present solution can omit the handle in the prior art, avoid the handle from blocking the nameplate on the box door, and has strong versatility and can be applied to containers 200 of different specifications. An operator only needs to operate the switch to achieve unlocking or locking, which is simple and labor-saving.
[0058] In a preferred embodiment, as shown in Figure 3 The electric drive assembly includes an electromagnet 23 and a magnetic block 22 made of magnetic material. The electromagnet 23 is fixed in the hollow structure of the lock rod 11, for example, the electromagnet 23 is fixed to a fixing member 25 by fasteners such as screws, and the fixing member 25 is fixed to the lock rod 11 by fasteners such as screws. In the embodiment shown in Figure 3 The outer wall of the fixing member 25 is uniformly arranged with a plurality of first fixing holes in the circumferential direction, and the lock rod 11 is provided with second fixing holes, that is, the fasteners pass through the second fixing holes and the first fixing holes to achieve the fixed connection of the fixing member 25 and the lock rod 11. The magnetic block 22 is fixed to the lock head 13, and the electromagnet 23 and the magnetic block 22 are arranged in the axial direction of the lock rod 11.
[0059] The electric drive assembly further includes a power supply 24 for providing direct current, and the electromagnet 23 is connected in series with the operating switch 21 and the power supply 24. The power supply 24 supplies power to the coil of the electromagnet 23 when the operating switch 21 is turned on. The power supply 24 is preferably a rechargeable battery unit, which ensures the normal use of the door lock structure 100 and also meets the function of continuous power supply. The battery unit can be arranged in the door body 210 or the side plate of the container 200 through a battery box, and the battery unit is detachably connected in the battery box. The battery unit can adopt a plug-in structure to achieve mechanical connection between the battery box, and adopt a contact connection mode to achieve electrical connection between the two, wherein the contact is arranged on the plug-in structure to achieve mechanical connection and electrical connection between the two.
[0060] In the on state of the operating switch 21, the electromagnet 23 is powered to form a magnetic field. The electromagnet 23 can attract the magnetic block 22, thereby driving the lock head 13 to move. For example, the electromagnet 23 is arranged at a position closer to the lock seat 12 relative to the magnetic block 22, so that the lock head 13 moves in the direction close to the lock seat 12 to extend into the lock hole of the lock seat 12, and the door lock structure 100 enters the locked state. For example, the electromagnet 23 is arranged at a position farther away from the lock seat 12 relative to the magnetic block 22, so that the lock head 13 moves in the direction away from the lock seat 12 to disengage from the lock seat 12, and the door lock structure 100 enters the unlocked state.
[0061] When the magnetic block 22 is made of hard magnetic material and has fixed magnetic poles, the electromagnet 23 can attract or repel the magnetic block 22 according to the direction of the current, so as to drive the lock head 13 to move away from or close to the lock seat 12, to realize unlocking or locking. Similarly, the electromagnet 23 can be arranged in the lock rod 11 to be closer or farther away from the lock seat 12 relative to the magnetic block 22.
[0062] Preferably, the electromagnet 23 is arranged at a position away from the lock seat 12 relative to the lock head 13, and the magnetic block 22 is fixedly connected to the first end of the lock head 13. The first end of the lock head 13 and the magnetic block 22 are fixedly connected, for example, by threaded connection, bolt connection, etc.
[0063] In a specific embodiment, the door lock structure 100 is switched from the locked state to the unlocked state by the control of the electric drive assembly, and is switched from the unlocked state to the locked state by the elastic member 30.
[0064] The electric drive assembly is arranged to control the electromagnet 23 to drive the lock head 13 to move away from the lock hole to the position where the lock head 13 is separated from the lock hole when the operation switch 21 is turned on. The operation switch 21 is preferably a delay switch, and after the operator presses the operation switch 21, the lock head 13 moves to the position where it is separated from the lock seat 12, and the operation switch 21 automatically disconnects the circuit after a predetermined time, and the lock head 13 returns to the locked state under the action of the elastic member 30.
[0065] In another specific embodiment, the electric drive assembly can control the door lock structure 100 to switch from the locked state to the unlocked state, and can control the door lock structure 100 to switch from the unlocked state to the locked state.
[0066] The magnetic block 22 is made of hard magnetic material and has fixed magnetic poles. The operation switch 21 is a double-pole double-throw switch, has a first connection end and a second connection end, and the control circuit is a double-pole double-throw switch circuit. When the operator connects the operation switch 21 with the first connection end, the direction of the current in the coil of the electromagnet 23 is opposite to that when the operator connects the operation switch 21 with the second connection end. Therefore, the operator can control the electromagnet 23 to attract or repel the magnetic block 22 by operating the operation switch 21, and further control the moving direction of the lock head 13. Preferably, the door lock structure 100 is also provided with an elastic member 30 at the same time, to ensure the reliability of the locking function, and to keep the door lock structure 100 in the locked state during power failure of the electric drive assembly.
[0067] To enable the elastic member 30 to drive the lock head 13 to restore the door lock structure 100 to the locked state, the lock rod 11 is fixed with a positioning member 31, and the two ends of the elastic member 30 act on the positioning member 31 and the lock head 13 respectively to drive the lock head 13 to move towards the lock hole to the second end extending into the lock hole. The positioning member 31 is a ring-shaped or columnar member fixed to the inner wall of the lock rod 11. The elastic member 30 is preferably a spring.
[0068] It should be noted that the two ends of the elastic member 30 acting on the positioning member 31 and the lock head 13 respectively can include that the two ends of the elastic member 30 respectively have a pulling force on the positioning member 31 and the lock head 13, or can include that the two ends of the elastic member 30 respectively have a pushing force on the positioning member 31 and the lock head 13. In other words, the elastic member 30 can drive the lock head 13 to move by pushing force or pulling force. For example, the positioning member 31 is arranged in the lock rod 11 away from the lock seat 12 relative to the first end of the lock head 13, and the two ends of the elastic member 30 abut against the positioning member 31 and the first end of the lock head 13 respectively, which can push the lock head 13 to move towards the lock seat 12. For another example, the positioning member 31 is arranged in the lock rod 11 close to the lock seat 12 relative to the first end of the lock head 13, and the two ends of the elastic member 30 are connected to the positioning member 31 and the lock head 13 (such as a radial protruding part close to the first end of the lock head 13), which can pull the lock head 13 to move towards the lock seat 12.
[0069] In a preferred embodiment, the positioning member 31 is ring-shaped, the positioning member 31 is fixed in the lock rod 11 close to the lock seat 12 relative to the first end of the lock head 13, and the lock head 13 passes through the center hole of the positioning member 31 and is movable relative to the positioning member 31. The lock head 13 is generally columnar, and the lock head 13 is provided with a first flange protruding radially outward, the first flange is close to the lock seat 12 relative to the positioning member 31, and the elastic member 30 abuts between the first flange and the positioning member 31. In this way, the elastic member 30 overlaps the lock head 13 in the axial direction of the lock rod 11 without protruding from the lock head 13, avoiding the length of the hollow structure of the end of the lock rod 11 being too long to affect the strength of the lock rod 11.
[0070] To avoid the lock head 13 moving outwardly too much, the end of the lock rod 11 includes a limiting member 33 protruding radially inward to limit the movement of the lock head 13. The lock head 13 is provided with a second flange protruding radially outward, the second flange is located in the hollow structure of the lock rod 11 and is further away from the lock seat 12 relative to the limiting member 33, and the limiting member 33 overlaps the second flange in the axial direction of the lock rod 11. In other words, the maximum outer diameter of the second flange is greater than the minimum inner diameter of the limiting member 33, so that the second flange cannot move from the hollow structure to the outside of the lock rod 11.
[0071] It should be noted that the limiting piece 33 can be completely or partially arranged in the circumferential direction of the lock rod 11, that is, the limiting piece 33 is annular or one or more arc-shaped in the circumferential direction of the lock rod 11. The first flange and the second flange can be outwardly protruding in the entire circumferential direction of the lock head 13 or partially outwardly protruding in the circumferential direction. Preferably, as shown in Figure 3 the first flange and the second flange can be the same flange 32.
[0072] In some specific embodiments, the lock rod 11 can be hollow only at one end, that is, one end of the door body 210 is provided with a lock head 13 and a corresponding lock seat 12. Preferably, the upper and lower ends of the door body 210 are fixed by the lock head 13, the lock seat 12 and the door frame 220. The two lock heads 13 of the upper and lower ends of the door body 210 can be arranged on two different lock rods 11 respectively. Alternatively, the two lock heads 13 of the upper and lower ends of the door body 210 can be arranged at the two ends of the same lock rod 11, that is, the two ends of the lock rod 11 are hollow structures, and the lock assembly 10 includes two lock heads 13 and two lock seats 12. At the same time, the same door body 210 can be provided with multiple lock assemblies 10, that is, the door lock structure 100 includes multiple lock assemblies 10. The multiple lock assemblies 10 of the door lock structure 100 can be controlled by the same electric drive assembly to move the lock head 13 at the same time to achieve simultaneous unlocking or locking, which is convenient to operate.
[0073] The utility model also provides a kind of container 200, container 200 includes according to above-mentioned door lock structure 100, door body 210 and door frame 220. Door body 210 is fixedly connected with lock rod 11, for example by several brackets, preferably lock rod 11 is arranged along the height direction of container 200. Door frame 220 is fixedly connected with lock seat 12, and the locking or release of door body 210 and door frame 220 can be realized by moving the lock head 13 movably connected with lock rod 11. Wherein, lock assembly 10 is arranged in the inside or outside of container 200, that is, the inside or outside of door body 210.
