Detailed Implementation

[0032] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] See Figures 5-10 This utility model provides a technical solution:

[0034] Example:

[0035] like Figures 5-10 As shown, a panel locking knob structure that is easy to automate assembly includes a locking knob 2, a toggle piece 4, and a connector. The toggle piece 4 and the connector, as well as the connector and the panel 1, are connected by a snap-fit ​​connection.

[0036] When the connector is engaged with the panel 1, the actuating piece 4 is perpendicular to the panel 1.

[0037] like Figure 6As shown, the connector includes a connecting rod 6, one end of which is connected to the deadbolt knob 2, and the other end of which is provided with a connecting part coaxial with it. The end of the connecting part away from the connecting rod 6 is provided with a first buckle 7 for connecting the toggle piece 4, and the end of the connecting part near the connecting rod 6 is provided with a second buckle 8 for connecting the panel 1 (i.e., cooperating with the panel 1).

[0038] The actuating piece 4 is provided with a protrusion 9 that is adapted to the first buckle 7.

[0039] The second buckle 8 includes at least two elastic pieces 10, the cross-section of which is wedge-shaped. (The larger end of the elastic piece 10 is larger than the size of the deadbolt insertion end (i.e., the part where the deadbolt knob 2 is connected to the connecting rod 6).

[0040] The connecting part is provided with positioning holes along the axial direction;

[0041] The actuating piece 4 includes a coaxial actuating part 11 and a limiting part 12. The size of the actuating part 11 is larger than the size of the limiting part 12. The limiting part 12 is adapted to the positioning hole. The protrusion 9 is disposed on the limiting part 12.

[0042] The deadbolt knob 2 and the connector are an integrated structure.

[0043] The locking knob 2 and the connecting parts are injection molded from high-strength plastic, wherein the high-strength plastic can be, but is not limited to, engineering plastic ABS.

[0044] The connecting rod 6, the first buckle 7, and the second buckle 8 are an integrated structure.

[0045] During installation, the limiting part 12 of the actuating piece 4 is inserted into the positioning hole through the first latch 7. When the end of the actuating piece 4 enters the bottom of the positioning hole, the actuating piece 4 is in place. During this process, the protrusion 9 matches the hook-shaped first latch 7, so that the actuating piece 4 is latched onto the deadbolt 2 through the connector. When the actuating piece 4 is latched onto the deadbolt 2, the actuating piece 4 is coaxial with the connecting rod 6.

[0046] Then insert the toggle piece 4 and the deadbolt knob 2 into the panel 1. During this process, when the large end of the elastic piece 10 of the second buckle 8 enters the hole of the deadbolt knob 2 on the panel 1, the large end of the elastic piece 10 first retracts. When the large end of the elastic piece 10 has completely passed through the hole of the deadbolt knob 2 on the panel 1, the large end of the elastic piece 10 returns to its original position and abuts against the panel 1. At this time, the installation of the deadbolt knob 2 is completed.

[0047] After the handle panel 1 is assembled, the actuating piece 4 is included in the installation accessory package. During installation, the customer simply inserts the actuating piece 4 into the knob hole. After the first latch 7 on the deadbolt knob 2 returns to its original position, the actuating piece 4 is limited, allowing for normal installation. The rigid positioning perpendicular to the surface facilitates installation and positioning. At this time, the actuating piece 4 is limited in multiple directions, and with the actuating piece 4 perpendicular to the bottom of the panel 1, it can be easily inserted into the corresponding hole in the lock body to open and close the safety latch. This structure is also simpler, requiring only alignment with the hole in the panel 1 for insertion, laying the foundation for fully automatic assembly.

[0048] The locking knob 2 is designed as a flexible snap-fit ​​structure. The locking knob 2 is directly inserted into the panel 1. After the second snap-fit ​​8 returns to its original position, the locking knob 2 is axially positioned, which is also very easy to automate.

[0049] This utility model uses a snap-fit ​​connection between the locking knob, panel, and toggle piece. While maintaining the same function, it reduces the number of parts, simplifies the assembly process, lays the foundation for automated assembly, and improves the product's economy and ease of installation.

[0050] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
