The fastening block is provided with a first groove, and the mounting block is provided with a second groove. The first groove and the second groove surround to form the through hole.

[0012] In one embodiment, the telescopic arm includes a plurality of telescopic components, all of which are sequentially fitted onto the mounting rod.

[0013] In any two adjacent telescopic members, the outer telescopic member is fitted over the telescopic member that is at least partially located on the inner side.

[0014] In one embodiment, each of the telescopic components includes a rod and a locking block. All the rods are sequentially fitted onto the mounting rod. The locking block is located at the end of the rod near the loop rope. The locking block located on the innermost rod is used to lock the position of the mounting rod.

[0015] In any two adjacent rods, the locking block on the outer rod is used to lock the inner rod that is adjacent to it.

[0016] In one embodiment, the lock block includes a first latch and a first locking member. The first latch is disposed on the rod body, and the first latch has two first latches spaced apart circumferentially thereon. The first locking member connects the two first latches and can drive the two first latches to move toward each other.

[0038] Refrigerated containers, commonly known as "freezers" or "frozen containers," are special containers equipped with refrigeration equipment for transporting goods requiring temperature control. To ensure the proper functioning of refrigerated containers, they typically require long power cables. During actual production and research, researchers have found that workers often need to use ladders to climb to a higher position to reach the external connectors of the power cables, which often presents a significant safety risk.

[0039] This utility model proposes a retractable retrieval device and a refrigerated container, aiming to solve the technical problem of high safety risks for workers when retrieving power cables from refrigerated containers.

[0040] Please see Figures 1 to 3 In one embodiment of this utility model, the retractable retrieval device is applied to a refrigerated container. The refrigerated container includes a power supply cable with an external connector. The retractable retrieval device includes a telescopic arm 1, a mounting rod 2, and a rope 3. The mounting rod 2 is fitted into the telescopic arm 1 and can extend out of the telescopic arm 1. The first end of the rope 3 is located at the end of the mounting rod 2 that extends out of the telescopic arm 1, and the second end of the rope 3 is provided with a connecting block 300. The connecting block 300 is connected to the rope 3, and the connecting block 300 and the rope 3 together form a socket for the external connector to be inserted.

[0041] The technical solution of this utility model reduces the difficulty for operators to retrieve power cables and ensures their safety by telescopically mounting the installation rod 2 onto the telescopic arm 1 and providing a loop 3 for securing external connectors at one end of the installation rod 2 that extends beyond the telescopic arm 1. In this embodiment, by telescopically mounting the installation rod 2 onto the telescopic arm 1, the length of the retrieval device can be extended to facilitate operators in retrieving power cables from refrigerated containers located at higher elevations. By providing the loop 3 at one end of the installation rod 2 that extends beyond the telescopic arm 1 and providing a connecting block 300 that can connect to the loop 3, the connecting block 300 and the loop 3 can form a loop hole for securing external connectors. Specifically, when retrieving the power cable of a refrigerated container, the operator can extend the mounting rod 2 out of the telescopic arm 1 until the retrieval device reaches the required length. The operator can then grasp and manipulate the telescopic arm 1, causing the lanyard 3 to be secured to the external connector. The operator can then gradually retract the mounting rod 2, moving the external connector closer for easy retrieval. It should be noted that when retracting the mounting rod 2, the operator can adjust the position of the telescopic arm 1 as needed to bring the external connector closer for easier retrieval. When using this telescopic retrieval device to retrieve the external connector of a refrigerated container, the operator does not need to climb to a high place, effectively reducing the safety risks and ensuring operator safety. This telescopic retrieval device can be applied to refrigerated containers or other scenarios requiring the retrieval of items at high locations.

[0042] It should be noted that the connecting block 300, in addition to connecting to the loop 3, can also connect to the mounting rod 2, provided that a socket for inserting an external connector is formed between the connecting block 300 and the loop 3. Specifically, the connecting block 300 is connected to the mounting rod 2, and the connecting block 300, the loop 3, and the mounting rod 2 together form a socket for inserting an external connector. Accordingly, to reduce the possibility of the external connector falling off after the loop 3 is secured, the connecting block 300 can be slidably mounted on the mounting rod 2.

[0043] Please see Figure 2 In one embodiment of this utility model, the connecting block 300 is provided with a through hole 310, and the loop 3 is threaded through the through hole 310. In this embodiment, threading the loop 3 through the through hole 310, that is, slidably connecting the connecting block 300 to the loop 3, can reduce the possibility of the external connector falling off after the loop 3 is secured. Specifically, after the operator secures the loop 3 to the external connector, as the operator retracts the installation rod 2, the connecting block 300 will gradually move along the loop 3 away from the installation rod 2 to gradually tighten the external connector.

[0044] In one embodiment of this utility model, the connecting block 300 includes a mounting block and a fastening block. The mounting block is disposed on the loop 3, one side of the fastening block is rotatably connected to one side of the mounting block, and the other side of the fastening block is engaged with the other side of the mounting block. A first groove is provided on the fastening block, and a second groove is provided on the mounting block. The first groove and the second groove together form a through hole 310. In this embodiment, the through hole 310 formed by the mounting block and the fastening block can improve the assembly flexibility of the retractable object retriever. It should be noted that, during the manufacturing of this retractable object retriever, to ensure that the lanyard 3 is threaded through the through hole 310, it needs to be threaded through the through hole 310 before installing the lanyard 3 onto the mounting rod 2. However, this operation is easily overlooked during actual manufacturing. The retractable object retriever, by using the mounting block and the fastening block to form the through hole 310, allows the lanyard 3 to be threaded through the through hole 310 after it has been installed onto the mounting rod 2. This effectively reduces the number of rework operations required during the manufacturing of the retractable object retriever. In a specific embodiment, to facilitate operator confirmation that the lanyard 3 is properly secured to the external connector, a camera that can wirelessly connect to a display device can be installed at the end of the mounting rod 2 near the lanyard 3.

[0045] Please see Figure 3 In one embodiment of this utility model, the telescopic arm 1 includes a plurality of telescopic components 100, all of which are sequentially fitted onto the mounting rod 2. In any two adjacent telescopic components 100, the outer telescopic component 100 is fitted onto at least part of the inner telescopic component 100. In this embodiment, the telescopic arm 1 is composed of a plurality of sequentially fitted telescopic components 100, which can effectively extend the length of the telescopic retrieval device, enabling the operator to reach the external connector at a higher position. It should be noted that the outermost telescopic component 100 can be used as a grip for the operator. Furthermore, to prevent the inner telescopic component 100 and the mounting rod 2 from slipping off the end of the outermost telescopic component 100 away from the rope 3, a sealing cap can be installed on the end of the outermost telescopic component 100 away from the rope 3.

[0046] Please see Figure 3In one embodiment of this utility model, each telescopic component 100 includes a rod 110 and a locking block 120. All rods 110 are sequentially fitted onto the mounting rod 2. The locking block 120 is located at the end of the rod 110 near the loop 3. The locking block 120 on the innermost rod 110 is used to lock the position of the mounting rod 2. In any two adjacent rods 110, the locking block 120 on the outer rod 110 is used to lock the inner and adjacent rod 110. In this embodiment, the following description will use the locking between two adjacent telescopic components 100 as an example: by locking the corresponding rod 110 with the locking block 120 located at the end of the rod 110 near the loop 3, the structural stability of the telescopic object retriever when extended can be ensured. Specifically, when the operator extends each telescopic component 100, the locking block 120 on the outer telescopic component 100 can lock the inner and adjacent rod 110, ensuring the stability of each telescopic component 100 after extension. When it is necessary to retract the telescopic component 100, the operator can release the inner and adjacent rod 110 through the locking block 120 on the outer telescopic component 100 to retract each telescopic component 100.

[0047] Please see Figure 4 In one embodiment of this utility model, the locking block 120 includes a first latch 121 and a first locking member 122. The first latch 121 is disposed on the rod body 110, and two first latches 1211 are spaced apart along its circumference. The first locking member 122 connects the two first latches 1211 and can drive the two first latches 1211 to move towards each other. In this embodiment, the first latch 121 is an incompletely closed annular structure. When locking the telescopic member 100, the operator only needs to adjust the first locking member 122 on the outer and adjacent telescopic member 100, causing the two corresponding first locking tongues 1211 to move closer to each other. This allows the corresponding first latch 121 to grip the rod 110, locking the telescopic member 100. Conversely, when releasing the telescopic member 100, the operator only needs to adjust the first locking member 122 on the outer and adjacent telescopic member 100, causing the two corresponding first locking tongues 1211 to move further apart under the rebound force of the corresponding first latch 121. This allows the corresponding first latch 121 to release the rod 110, releasing the position lock of the telescopic member 100. By using the first locking member 122 on the outer and adjacent telescopic member 100 to drive the two corresponding first locking tongues 1211 to move closer or further apart to lock and release the telescopic member 100, the operation process is simplified and the difficulty of operation is reduced.

[0048] In one embodiment of this utility model, the first locking member 122 includes a first locking rod 1221 and a lever 1222. The first end of the first locking rod 1221 is disposed on one of the first locking tongues 1211, and the second end of the first locking rod 1221 passes through the other first locking tongue 1211. The lever 1222 is rotatably connected to the second end of the first locking rod 1221 and abuts against the other first locking tongue 1211. An extension plate 1223 for the operator to grip is provided on the lever 1222. In this embodiment, the lever 1222 has a locked position and a released position. When the lever 1222 rotates from the released position to the locked position, it drives the two first locking tongues 1211 to move closer to each other. Specifically, when locking and releasing the telescopic rod, the operator only needs to rotate the lever 1222 located on the outer and adjacent telescopic member 100 to switch the position of the lever 1222, which simplifies the operation process and reduces the difficulty of operation. The extension plate 1223 provided on the lever 1222 is used for the operator to hold and rotate the lever 1222. In a specific embodiment, the rotation axis of the lever 1222 is perpendicular to the central axis of the first locking rod 1221, and the lever 1222 has a quasi-eccentric wheel structure; that is, the distance between the lever 1222 and the corresponding first locking tongue 1211 when the lever is in the locked position is less than the distance between the lever 1222 and the corresponding first locking tongue 1211 when the lever is in the released position.

[0049] In one embodiment of this utility model, the first locking member 122 further includes a first adjusting block 1224; the first adjusting block 1224 is movably disposed at the first end of the first locking rod 1221 and can abut against the corresponding first locking tongue 1211. The first adjusting block 1224 can drive the two first locking tongues 1211 to move towards each other. The first adjusting block 1224 is provided with a plurality of first gripping plates 1225 along its circumference. In this embodiment, the first adjusting block 1224 can drive the two first locking tongues 1211 to move towards each other to adjust the locking force of the first latch 121. In actual use, the operator can rotate the first adjusting block 1224 according to actual needs to adjust the locking force when the locking block 120 locks the rod 110 located on the inner side. The first gripping plates 1225 provided on the first adjusting block 1224 facilitate the operator to rotate the first adjusting block 1224. In a specific embodiment, the first adjusting block 1224 is threadedly connected to the first end of the first locking rod 1221.

[0050] Please see Figure 4In one embodiment of this utility model, the locking block 120 further includes a second latch 123 and a second locking member 124. The second latch 123 covers the rod body 110 and is integrally formed with the first latch 121. The second latch 123 is provided with two second latches 1231 at intervals along its circumference. The second locking member 124 includes a second locking rod 1241 and a second adjusting block 1242. The second locking rod 1241 passes through the two second latches 1231 in sequence. The second adjusting block 1242 is movably disposed at one end of the second locking rod 1241 and can abut against the corresponding second latch 1231. The second adjusting block 1242 can drive the two second latches 1231 to move toward each other. The second adjusting block 1242 is provided with a plurality of second grip plates 1243 along its circumference. In this embodiment, the second latch 123 and the second locking member 124 are used to lock the locking block 120 to the corresponding rod 110, so as to fix the locking block 120 to the corresponding rod 110 more stably and reliably. Specifically, the second locking member 124 includes a second locking rod 1241 and a second adjusting block 1242, wherein the second adjusting block 1242 can drive the two second locking tongues 1231 to move towards each other, so as to adjust the locking force of the second latch 123. The second grip plate 1243 provided on the second adjusting block 1242 facilitates the operator to rotate the second adjusting block 1242. In a specific embodiment, the second adjusting block 1242 is threadedly connected to the second locking rod 1241.
