Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-6This utility model provides an embodiment of a self-resetting latching switch structure with rotary unlocking, including a panel body 1. To ensure the ventilation of the panel body 1, a number of ventilation patterns for ventilation and heat dissipation are opened on the outer surface of the panel body 1. A latching groove 2 is opened on one side of the panel body 1, and a locking latching plate 3 is provided in the latching groove 2. The upper and lower ends of the back of the locking latching plate 3 are fixedly installed with sleeve side ears 5. A sleeve rod 4 is fixedly installed on one side of the back of the panel body 1. The sleeve rod 4 is set through the sleeve side ears 5, and the sleeve side ears 5 are movably sleeved on the outside of the sleeve rod 4. This allows the locking latching plate 3 to rotate and open on the sleeve rod 4. At the same time, the sleeve rod 4 can limit the locking latching plate 3 to prevent the locking latching plate 3 from moving left and right, which has a good rotation limiting effect.

[0028] The sleeve rod 4 is equipped with several evenly distributed reset torsion springs 6. The two spring rods of the reset torsion springs 6 are in elastic contact with the locking plate 3. When the locking plate 3 is rotated on the sleeve rod 4, the sleeve rod 4 will exert rotational torque on the reset torsion springs 6 during manual pulling, causing the reset torsion springs 6 to produce a certain elastic deformation. The reset torsion springs 6 convert mechanical energy into potential energy and store it. When the external pulling force is removed, the elastic restoring force releases the potential energy as a reset rotational force. Thus, through the action of the reset torsion springs 6, the locking plate 3 can be driven to automatically and elastically reset after no external force is applied, which has the effect of a self-resetting lock and makes the structure more convenient to use.

[0029] Furthermore, a lock cylinder 9 is installed on the side of the panel body 1 near the locking plate 3, a lock tongue 10 is fixedly installed on the back of the lock cylinder 9, a locking protrusion 8 adapted to the lock tongue 10 is provided in the middle of the locking plate 3, and several locking claws 7 are fixedly installed on the outer wall of one side of the locking plate 3.

[0030] Based on the above structure, when the panel body 1 of this utility model is in use, it can be installed on the appropriate chassis by means of a movable hinge. After the panel assembly is installed, the locking claw 7 of the locking plate 3 can be locked on the external chassis, thereby locking and closing the panel body.

[0031] When the locking plate 3 is subjected to external tension, it rotates and opens on the sleeve rod 4 under the action of the external force. During the rotation and opening of the locking plate 3, the locking claw 7 on one side can move synchronously. At this time, the locking claw 7 can disengage from the externally adapted chassis locking groove, and the locking plate 3 opens to a certain angle, as detailed in the attached instruction manual. Figure 5 As shown, the panel body 1 can be rotated open when it is not locked by the locking claw 7.

[0032] When the user releases the locking plate 3, the external tension disappears, and the return torsion spring 6 drives the locking plate 3 to rotate in the opposite direction and close. At this time, the locking claw 7 can re-engage into the chassis locking groove, thus completing the locking and closing of the locking plate 3. See the attached instruction manual for details. Figure 1 As shown;

[0033] When it is necessary to finally lock the locking plate 3, the key can be inserted into the lock cylinder 9. After the key is inserted, the lock cylinder 9 can be rotated counterclockwise. When the lock cylinder 9 rotates counterclockwise, it will simultaneously drive the bolt 10 to move, thereby moving the bolt 10 to directly below the locking protrusion 8. The specific state is as shown in the attached instruction manual. Figure 6 As shown, the locking tongue 10 can lock and limit the locking plate 3 by blocking the structure. At this time, due to the blocking structure of the locking tongue 10, the external pulling force cannot pull the locking plate 3 to rotate and open. The locking claw 7 is always placed in the lock slot of the chassis, so the panel body 1 cannot be opened as a whole. It has the privacy effect of rotation locking and rotation unlocking. Only personnel equipped with the key of the lock cylinder 9 can open the panel.

[0034] In this embodiment, in order to facilitate the integrated production and molding of the locking plate 3, the sleeve side lug 5 and the locking plate 3 adopt an integrated molding structure design, and the locking plate 3 and the locking claw 7 adopt an integrated molding structure design.

[0035] In this embodiment, the specific details are as shown in the appendix to the specification. Figure 4 As shown, the back of the locking plate 3 is provided with a limiting groove that is compatible with the reset torsion spring 6. The spring rod of the reset torsion spring 6 is placed in the limiting groove 13. The limiting groove 13 can limit the reset torsion spring 6, preventing the reset torsion spring 6 from sliding up and down on the sleeve rod 4, thus achieving the practical effect of limiting the upper and lower parts of the reset torsion spring 6.

[0036] In this embodiment, in order to protect the structure of the locking plate 3, as per the appendix to the instruction manual... Figure 2 As shown, an outer protective plate 11 for protecting the locking plate is fixedly installed on the back of the panel body 1 and on the outside of the locking plate 3.

[0037] In this embodiment, in order to facilitate the locking plate 3 to be pulled up and pulled, a protruding handle 12 is provided in the middle of the front of the locking plate 3. The handle 12 and the locking plate 3 adopt an integral molding structure design. The user can insert his / her fingers into the handle 12 to pull the locking plate 3 to open and rotate it.

[0038] Working principle: When in use, the panel body 1 of this utility model can be installed on the appropriate chassis by means of a movable hinge. After the panel assembly is installed, the locking claw 7 of the locking plate 3 can be locked on the external chassis, thereby locking and closing the panel body.

[0039] When the latch 12 of the locking plate 3 is subjected to external tension, the locking plate 3 rotates and opens on the sleeve rod 4 under the action of the external force. During the rotation and opening of the locking plate 3, the locking claw 7 on one side can move synchronously. At this time, the locking claw 7 can disengage from the externally adapted chassis locking groove, and the locking plate 3 opens to a certain angle, as detailed in the attached instruction manual. Figure 5 As shown, the panel body 1 can be rotated open when it is not locked by the locking claw 7.

[0040] When the user releases the locking plate 3, the external tension disappears, and the return torsion spring 6 drives the locking plate 3 to rotate in the opposite direction and close. At this time, the locking claw 7 can re-engage into the chassis locking groove, thus completing the locking and closing of the locking plate 3. See the attached instruction manual for details. Figure 1 As shown;

[0041] When it is necessary to finally lock the locking plate 3, the key can be inserted into the lock cylinder 9. After the key is inserted, the lock cylinder 9 can be rotated counterclockwise. When the lock cylinder 9 rotates counterclockwise, it will simultaneously drive the bolt 10 to move, thereby moving the bolt 10 to directly below the locking protrusion 8. The specific state is as shown in the attached instruction manual. Figure 6 As shown, the locking tongue 10 can lock and limit the locking plate 3 by blocking the structure. At this time, due to the blocking structure of the locking tongue 10, the external pulling force cannot pull the locking plate 3 to rotate and open. The locking claw 7 is always placed in the chassis lock slot, so the panel body 1 cannot be opened as a whole. It has the privacy effect of rotation locking and rotation unlocking. Only personnel equipped with the key of the lock cylinder 9 can open the panel.

[0042] In summary, this utility model, through the combined structure of the lock cylinder 9, the lock tongue 10, and the locking plate 3, achieves the practical effect of locking and limiting opening. Only personnel equipped with the lock cylinder key can rotate and open the panel, thus effectively improving the overall security of the panel and providing a private use effect for targeted personnel opening, preventing the theft of internal hardware and enhancing security. In actual use, the lock cylinder-type rotation unlocking mechanism provides security, effectively preventing unauthorized opening of the chassis by external personnel, better protecting the internal hardware structure, and making it more practical.

[0043] Meanwhile, the locking plate 3 can automatically and elastically reset under the action of the reset torsion spring 6, thus achieving the practical effect of a self-resetting locking mechanism. There is no need for manual pressing of the locking plate 3 to reset, making the structure more convenient to use and improving the performance.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
