[0014] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
[0015] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.
[0016] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.
[0017] Reference Figures 1 to 4 , a door lock knob for preventing accidental reverse locking, comprises a rear lock body 1, on which an reverse locking knob 2 for reverse locking is installed, an embedding groove 3 is arranged on the back side of the rear lock body 1, and an unlocking groove 4 and a reverse locking groove 5 are extended outwardly from the embedding groove 3, the reverse locking knob 2 is provided with a knob rod 9 which penetrates into the rear lock body 1, and a resettable embedding piece 6 is installed on the knob rod 9, the embedding piece 6 is embedded in the embedding groove 3, the embedding piece 6 is provided with a limiting piece 7 corresponding to the unlocking groove 4 and the reverse locking groove 5, and the limiting piece 7 is embedded in the unlocking groove 4 or the reverse locking groove 5 to realize the unlocking or reverse locking function. When reverse locking, the reverse locking knob 2 needs to be pressed to make the limiting piece 7 withdraw from the unlocking groove 4 before the reverse locking knob 2 can be rotated, which can effectively avoid the occurrence of reverse locking due to accidental operation.
[0018] A limiting member 8 is installed on the back side of the rear lock body 1 . The limiting member 8 is provided with a through hole. The knob rod 9 passes through the through hole. A return spring 10 is sleeved on the knob rod 9 . One end of the return spring 10 abuts against the limiting member 8 .
[0019] The knob rod 9 is located between the embedded piece 6 and the limiting member 8 , and a limiting ring 11 is installed thereon. The return spring 10 is installed between the limiting member 8 and the limiting ring 11 .
[0020] Embodiment 1: The unlocking groove 4 and the anti-locking groove 5 are both independent groove structures, and the number is one. The position of the anti-locking groove 5 needs to be adjusted according to whether the door is opened leftward or rightward (such as Figure 3 as shown).
[0021] Embodiment 2: The unlocking groove 4 and the anti-locking groove 5 are both independent groove structures. The number of the unlocking groove 4 is one, and the number of the anti-locking grooves 5 is two. The anti-locking grooves 5 are symmetrically arranged on both sides of the unlocking groove 4 (such as Figure 4 As shown in the figure), it can be used for both left-hand and right-hand door locks.
[0022] Embodiment 3: The unlocking groove 4 is an independent groove structure. When the locking is reversed, the rotation trajectory of the limiting plate 7 is the reverse locking groove 5 , that is, a step structure is formed between the unlocking groove 4 and the reverse locking groove 5 .
[0023] In Examples 1 and 2, the process from unlocking to reverse locking, or the process from reverse locking to unlocking, requires pressing the reverse locking knob 2 to allow the limiting plate 7 to withdraw from the unlocking slot 4 or the reverse locking slot 5. In Example 3, the process from unlocking to reverse locking requires pressing the reverse locking knob 2 to allow the limiting plate 7 to withdraw from the unlocking slot 4. The process from reverse locking to unlocking requires directly rotating the reverse locking knob 2. When the limiting plate 7 rotates to the unlocking slot 4, the return spring 10 pushes the limiting plate 7 into the unlocking slot 4.
