A gear 151 is rotatably installed inside the transmission box 15, and a rack 152 that meshes with the gear 151 and can slide along the extension and retraction direction of the handle 2; one end of the rack 152 extending out of the pre-embedded box 1 is fixedly connected to the handle 2.
[0046] The gear 151 is fixedly connected to the swing arm 231, and a locking hook 23 is fixedly installed at one end of the swing arm 231 extending out of the pre-embedded box 1; the swing direction of the swing arm 231 is opposite to the extension and retraction direction of the handle 2, specifically:
[0047] Handle 2 extends out of the embedded box 1, and swing rod 231 drives lock hook 23 to swing in the retraction direction;
[0048] Handle 2 retracts into embedded box 1, and swing rod 231 drives lock hook 23 to swing in the extension direction;
[0049] Optionally, the gear 151 is fixedly sleeved on the gear shaft, and the two ends of the gear shaft are rotatably mounted on the inner wall of the transmission box 15; the rocker arm 231 is fixedly connected to the gear shaft and swings accordingly as the gear 151 rotates.
[0050] Furthermore, the front end of the handle 2 is provided with a cover 21, a shielding screw, and other structures to make the appearance flat and beautiful.
[0051] See Figure 6 This utility model also provides a self-locking freezer, which has a lid 5 and a cabinet body; combined with Figure 7 The cabinet body is fitted with an inner liner 6; the pre-embedded box 1 of the telescopic handle assembly is embedded in the cover 5; see also Figure 8 The inner liner 6 has a locking hole for engaging with the locking hook 23; specifically,
[0052] Handle 2 retracts into the embedded box 1, and the swing rod 231 drives the locking hook 23 to swing in the extension direction, and the locking hook 23 inserts into the lock hole; locking the cover 5 to prevent it from opening;
[0053] Extend handle 2 out of the pre-embedded box 1, and swing rod 231 drives lock hook 23 to swing in the retracting direction, and lock hook 23 disengages from the lock hole; the cover 5 can be opened and closed.
[0054] The self-locking freezer of the present invention has a retracted handle 2 that locks the lid 5, preventing children from accidentally opening the freezer and improving safety. When the handle 2 is extended, the lock is released, and the opening and closing of the lid 5 is not hindered.
[0055] Furthermore, a limiting sleeve 14 is also fixedly installed on the pre-embedded box 1 to accommodate the swing rod 231 and the locking hook 23, and extends into the cabinet body; specifically:
[0056] The handle 2 extends out of the pre-embedded box 1, and the swing rod 231 and the locking hook 23 are stored in the limiting sleeve 14; when taking or putting away items, avoid getting caught on the locking hook 23.
