Description

Technical Field

[0001] The utility model relates to the technical field of smart locks, in particular to a smart lock specially used for logistics transportation. Background Art

[0002] Intelligent logistics electronic locks, through the mobile GPRS wireless network system, can achieve uninterrupted real-time monitoring and real-time alarm for the entire process of cargo transportation, so that regulatory units, transportation companies and cargo owners can grasp the dynamics of cargo flow in real time, ensure effective supervision during cargo transportation, improve the efficiency of customs clearance or inspection, thereby reducing corporate costs and enhancing competitiveness.

[0003] When the original smart logistics electronic lock is wet by rain, the lock buckle may rust, causing the lock buckle to be stuck on the lock body, making the lock buckle unable to be opened, reducing the service life of the smart logistics electronic lock. During transportation, the lock body collides with the car door, which may cause damage to the lock body, reducing the service life of the smart logistics electronic lock.

[0004] An existing patent (publication number: CN207813286U) discloses an intelligent logistics electronic lock for transportation, including a lock buckle, a display screen, a knob, a keyboard, an indicator light, a lock body, a buffer pad, a waterproof ring, a battery, a controller, a reset spring, a rotating shaft, a buckle and the adhesive plate. The front surface of the lock body is provided with the display screen and is fixedly connected to the display screen. The knob is provided below the display screen and is rotatably connected to the lock body. The waterproof ring is provided on the upper surface of the lock body. When it rains, rainwater contaminates the lock buckle, which may cause rust on the lock buckle and make the lock buckle unable to be opened from the lock body. The waterproof ring prevents the lock buckle from rusting, thereby improving the service life of the intelligent logistics electronic lock. A buffer pad is provided on the outer wall of the lock body. When the logistics vehicle is in transportation, the lock body collides with the vehicle door. The buffer pad reduces the degree of collision between the lock body and the vehicle door, prevents the lock body from being damaged by collision, and improves the service life of the intelligent logistics electronic lock.

[0005] However, the above technical solution still has certain shortcomings. During use, the smart lock is generally located at the rear of the car. After the car is locked with the smart lock, the smart lock will continue to swing during the driving of the vehicle, resulting in continuous collisions between the lock body and the car, thereby causing damage to the electronic components inside the smart lock. For this reason, a smart lock specifically for logistics transportation is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1:

[0029] like Figures 1 to 5 As shown, this embodiment provides a smart lock dedicated to logistics transportation, including: a lock body 1, a side wall of the lock body 1 is provided with a fixing mechanism 2;

[0030] The fixing mechanism 2 includes a fixing plate 201, a side wall of the fixing plate 201 is fixedly connected with a strong magnet 206, the inner wall of the fixing plate 201 is slidably connected with two groups of fixing pins 202 extending to the outside of the fixing plate 201, one end of the two groups of fixing pins 202 located outside the fixing plate 201 extends to the inside of the lock body 1, the lock body 1 is provided with a fixing groove 203 at the contact position with the fixing plate 201, the inner wall of the fixing plate 201 is rotatably connected with a tooth column 205, the tooth column 205 is provided with a torsion spring at the connection with the fixing plate 201, the two groups of fixing pins 202 are located inside the fixing plate 201 A group of first racks 204 are fixedly connected to one end, and the two groups of first racks 204 are respectively located on the upper and lower sides of the tooth column 205, and the two groups of first racks 204 are meshed with the tooth column 205 at the same time. The inner wall of the fixed plate 201 is slidably connected with a pull rod 207 extending to the outside of the fixed plate 201, and the end of the pull rod 207 located outside the fixed plate 201 is fixedly connected with a pull ring 208, and the end of the pull rod 207 located inside the fixed plate 201 is fixedly connected with a second rack 209, the second rack 209 is meshed with the tooth column 205, and the outer wall of the pull ring 208 is provided with a rubber coating.

[0031] The principle of this embodiment is as follows: the fixing plate 201 is adsorbed on the tailgate of the vehicle compartment by a strong magnet 206. Then, when the lock body 1 locks the vehicle compartment, the pull ring 208 is pulled so that the pull ring 208 drives the pull rod 207, thereby driving the second rack 209 to slide, so that the second rack 209 drives the tooth column 205 to rotate. During the rotation process, the tooth column 205 pushes the two groups of first racks 204 to move to both sides and twists the torsion spring. During the movement of the two groups of first racks 204, the two groups of fixing pins 202 are pushed outward from the fixing plate 201. Then the lock body 1 is placed between the two groups of fixing pins 202, and then the pull ring 208 is released. The torsion spring pushes the tooth column 205 to rotate in the opposite direction to reset. The tooth column 205 rotates in the opposite direction to drive the first rack 204 and the second rack 209 to reset, so that the pull rod 207 pulls the pull ring 208 to reset, and the two groups of fixing pins 202 approach each other, so that the two groups of fixing pins 202 are inserted into the fixing groove 203. At this time, the lock body 1 is fixed to the side wall of the fixing plate 201. When the lock body 1 needs to be taken out, the pull ring 208 is pulled again, so that the tooth column 205 pushes the two groups of fixing pins 202 away from each other again, so that the two groups of fixing pins 202 slide out of the fixing groove 203, and then the lock body 1 can be separated from the fixing plate 201.

[0032] Embodiment 2:

[0033] like Figure 4 and Figure 5 As shown, on the basis of retaining all the technical features in the specific embodiment 1 (or the difference between this embodiment and the specific embodiment 1 is that), in this embodiment: a protective mechanism 3 is arranged at the top of the fixed plate 201, and the protective mechanism 3 includes two groups of sliding rods 301, the two groups of sliding rods 301 are slidably connected to the inner wall of the fixed plate 201, and the ends of the two groups of sliding rods 301 extend to the outer wall of the fixed plate 201, and the end of the sliding rod 301 located outside the fixed plate 201 is sleeved with a rubber sleeve, and the end of the sliding rod 301 located inside the fixed plate 201 is fixedly connected to the limit pin 302, and the top of the limit pin 302 is an inclined inclined surface, and a reset spring 303 located inside the fixed plate 201 is arranged between the two groups of sliding rods 301, and the two groups of reset springs 303 are respectively fixedly connected to the outer wall of one group of sliding rods 301, and the outer sleeve of the lock body 1 is provided with a protective cover 304, and the inner wall of the protective cover 304 is fixedly connected with two groups of hooks 305, and the ends of the two groups of hooks 305 extend to the inside of the fixed plate 201.

[0034] Principle of this embodiment: After the lock body 1 and the fixing plate 201 are fixed together, the protective cover 304 is held by hand, and then the two sets of hooks 305 are inserted into the fixing plate 201 from the top of the fixing plate 201, so that the two sets of hooks 305 are in contact with the two sets of limit pins 302, thereby pushing the two sets of limit pins 302 to move closer to the middle. At this time, the two sets of limit pins 302 respectively push the two sets of sliding rods 301 to move closer to each other, so that the reset spring 303 is compressed. After the ends of the two sets of hooks 305 completely slide over the two sets of limit pins 302, the reset spring 303 rebounds, thereby pushing the two sets of sliding rods 301 to reset, and the two sets of sliding rods 301 are reset. 01 Push the two sets of limit pins 302 to reset, so that the two sets of limit pins 302 block the hook 305, so that the protective cover 304 is mounted on the outside of the lock body 1 and will not fall off. When the protective cover 304 needs to be removed, the two sets of sliding rods 301 are pushed closer to each other, so that the two sets of sliding rods 301 compress the reset spring 303 and drive the two sets of limit pins 302 to move closer to each other, so that the limit pins 302 and the hook 305 are not in contact. At this time, the protective cover 304 can be pushed upward, so that the protective cover 304 drives the hook 305 to slide out of the fixed plate 201, thereby separating the protective cover 304 from the lock body 1.
