[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.

[0023] like Figure 1As shown, the present application provides an electric rotary lock for a container, including a base 1 and a connecting seat 2, which are welded and fixed between the base 1 and the connecting seat 2, wherein a lock head 3 is rotatably connected between the base 1 and the connecting seat 2, a part of the lock head 3 extends between the base 1 and the connecting seat 2, the lock hole of the container will correspond to the lock head 3, and will be placed on the connecting seat 2, the lock head 3 will enter the lock hole, and by rotating the lock head 3, the lock head 3 and the opening part of the lock hole are misaligned, thereby achieving locking of the container and ensuring the position stability of the container when it moves.

[0024] like Figure 2 As shown, the base 1 and the connecting seat 2 are formed with a sliding mouth 4, the lock head 3 is formed with a guide rod 5, and the push rod 6 is sleeved outside the guide rod 5. The end of the guide rod 5 away from the lock head 3 is fixedly connected with a stop block 7, so that the push rod 6 cannot be directly separated from the guide rod 5. Part of the guide rod 5 and the push rod 6 are located outside the base 1 and the connecting seat 2 through the sliding mouth 4. The operator can rotate the lock head 3 by toggling the push rod 6, and then control the unlocking and locking of the lock head 3. When the lock head 3 is in the locked and unlocked state, the push rod 6 will abut against the two ends of the push rod 6 away from the sliding mouth 4, which makes it easy for the operator to judge whether to toggle the push rod 6 to the correct position.

[0025] like Figure 2 As shown, the connecting seat 2 is provided with a limiting assembly, the connecting seat 2 is provided with a connecting groove 9, the lock head 3 is provided with a limiting groove 10, the edge of the limiting groove 10 is provided with an arc surface, wherein the limiting assembly includes a spring 2 8 and a steel ball 11, the two ends of the spring 2 8 are respectively connected to the steel ball 11 and the bottom of the connecting groove 9, when the lock head 3 is in a locked state, part of the steel ball 11 will slide into the limiting groove 10 due to the elastic force of the spring 2 8, so that the lock head 3 cannot be rotated directly, ensuring the position stability of the lock head 3 when it is in a locked state, and then ensuring the stability of the container, when it needs to be unlocked, the push rod 6 is vigorously pushed, the arc surface of the steel ball 11 and the arc surface of the edge of the limiting groove 10, the steel ball 11 will push the spring 2 8 to deform, so that the steel ball 11 slides out of the limiting groove 10, so that the steel ball 11 will not affect the rotation of the lock head 3.

[0026] like Figure 2 and Figure 3 As shown, the base 1 is fixedly installed with a motor 15, and a transmission member 1 is installed at the output end of the motor 15. A transmission member 2 is movably installed between the base 1 and the connecting seat 2, wherein the transmission member 1 includes a ring gear 13, and the ring gear 13 is fixedly installed at the output end of the motor 15. The transmission member 2 includes a tooth block 14, and the tooth block 14 is fixedly connected to the push rod 6, and the tooth block 14 is meshed with the ring gear 13. When the motor 15 is working, the ring gear 13 rotates, which will drive the tooth block 14 and the push rod 6 to rotate, so that the motor 15 drives the push rod 6 and the lock head 3, quickly realizes the locking and unlocking of the container, and improves the convenience of loading and moving the container.

[0027] like Figure 3 and Figure 4 As shown, the push rod 6 is sleeved outside the guide rod 5 so that the push rod 6 and the gear ring 13 can slide relative to each other. The guide rod 5 is sleeved with a spring 12, and the two ends of the spring 12 are respectively connected to the push rod 6 and the lock head 3. The tooth block 14 and the gear ring 13 will remain engaged under the action of the spring 12. The relative position of the tooth block 14 and the gear ring 13 can be controlled by the push rod 6, so that the gear ring 13 and the tooth block 14 can be released from transmission. When the motor 15 fails and locks or cannot be driven, the elastic force of the spring 12 is overcome to push the push rod 6, and the push rod 6 is moved to release the engagement of the tooth block 14 and the gear ring 13, thereby releasing the connection between the motor 15 and the lock head 3, and relying on pushing the push rod 6, manual locking and unlocking are ensured to ensure the normal use of the rotary lock.

[0028] In summary, the rotary lock provided in this embodiment can quickly achieve locking and unlocking through the motor 15, thereby improving convenience. At the same time, when the motor 15 fails and locks or cannot be driven, the locking and unlocking can be manually controlled.

[0029] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
