[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0023] like Figure 1-3 As shown, the present invention proposes a thermally broken aluminum lock clutch structure, the clutch including a clutch housing frame 11 and a clutch housing cover 12 arranged in combination;

[0024] The clutch assembly includes a reset arm 21, a reset torsion spring 22 placed in the torsion spring groove of the reset arm 21, a first washer 23 and a second washer 24 symmetrically arranged on the end face of the reset arm 21 that contacts the through hole of the clutch housing frame 11, a reset arm retaining spring 25 placed in the retaining spring groove of the reset arm 21 that passes through one end of the clutch housing frame 11, and a hollow clutch sleeve 26 installed at the tail end.

[0025] The clutch has a clutch panel 31 and a clutch cover plate 32 with through holes on the outside;

[0026] The handle mechanism includes a handle 41 located at the threaded end of the reset arm 21, and the handle 41 is screwed to the reset arm 21 by a detachable handle nut 42.

[0027] In this embodiment, the design of the handle 41 itself and its connection with the clutch internal clutch component reset lever 21 are bidirectionally symmetrical. A detachable handle nut 42 is provided for clockwise and counterclockwise installation of the handle 41, realizing the left and right reversal function of the product to meet the needs of users with different door opening directions. The entire reversal process only requires disassembling the handle nut 42 and the clutch cover plate 32, which is time-saving and requires low skill from the installers, greatly shortening the on-site installation and debugging time. There is no need to distinguish between left and right opening, and only one general product needs to be produced and stored, which significantly reduces inventory management and logistics costs.

[0028] As an assembly example: the reset torsion spring 22 is installed into the torsion spring groove on the reset rotating arm 21, a washer is put in, the threaded end of the reset rotating arm 21 is passed through the reset rotating arm hole from inside the clutch module, and at the same time the reset torsion spring 22 is inserted into the torsion spring limiting groove. The washer is put into the reset rotating arm 21 and the reset rotating arm retaining spring 25 is inserted into the retaining spring groove. The motor is installed, the air suspension sleeve is installed, and the clutch box cover 12 is closed. The clutch assembly is completed.

[0029] Install the clutch into the clutch panel 31 and secure it with the cover bolt 33. Install the handle 41 into the reset arm 21 in the correct direction and secure it with the handle nut 42. Then install the clutch cover plate 32. The installation is now complete.

[0030] The reset arm 21 rotates relative to the clutch housing 11. The first washer 23 and the second washer 24 fitted on its outer wall are made of stainless steel. By using the first washer 23 and the second washer 24 made of stainless steel, the rotating parts are replaced with surface contact, thereby improving the wear resistance of the mechanism, making the handle reset action smoother, reducing wear, and extending the service life of the entire clutch.

[0031] To ensure a stable connection between the reset arm 21 and the handle 41, the end of the reset arm 21 that passes through the clutch panel 31 includes a square tube section and a threaded section. The handle 41 is fitted clockwise and counterclockwise around the outer circumference of the square tube section and the threaded section. The square tube section fits tightly with the square hole inside the handle, ensuring that the torque of the handle 41 can be transmitted to the reset arm 21 without loss. The handle 41 is threadedly locked onto the reset arm 21 by the threaded section and the fixing nut of the handle 41, preventing it from falling off axially during use.

[0032] The purpose of rotating the handle 41 clockwise and counterclockwise is to allow for interchangeable installation directions, enabling the left and right handles 41 to rotate to meet different door opening directions.

[0033] To ensure stable assembly of the clutch module box, the upper and lower side walls of the clutch box frame 11 and the clutch box cover 12 are further provided with matching elastic buckles. The center of the elastic buckle is provided with a screw hole for screwing in the bolt. The upper and lower side walls of the clutch box frame 11 and the clutch box cover 12 are designed with matching elastic buckles to achieve quick pre-positioning. The center of the elastic buckle is provided with a screw hole. By cooperating with the bolt, the clutch box frame 11 and the clutch box cover 12 are firmly fixed at the four corners, forming a connection strength far exceeding that of a structure with two diagonal screws.

[0034] In an optional embodiment, the clutch sleeve 26 is provided with a motor (not shown in the figure) that drives the handle 41 to rotate forward and backward. The motor is set as a drive mechanism to drive the door to open and close. The electric drive can be integrated with a fingerprint door lock device, and the motor can be driven by fingerprint touch control.

[0035] Understandably, the clutch sleeve 26 has a 270° fingerprint cable outlet hole, which can be used to connect the power supply device or battery to meet the cable routing requirements when the product is unlocked in different directions.

[0036] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
