[0041] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0042] See also Figures 1 - 13 An ecological door lock includes a handle unit, a clutch bracket 2, a lock rod unit 3, a positioning piece 4, a toggle unit and a positioning pin 5.

[0043] The handle unit includes a handle 11 and a handle seat 12, wherein the handle seat 12 is fixedly mounted on the door, and the handle 11 can rotate relative to the handle seat 12, at least including the handle rotating upward (lifting) and the handle rotating downward (pressing down). The specific installation and positioning of the handle 11 is related to the clutch bracket 2, as described below. The design of this application is mainly for the inner handle, and the outer handle is the same as the existing design, and can be locked and unlocked by fingerprints or key lock holes.

[0044] In this embodiment, the handle 11 includes a main shell 111 and a cover plate 112 detachably mounted on the main shell 111. A fixing plate 113 is mounted inside the main shell 111. A plurality of matching columns 114 are mounted on the main shell 111 or the fixing plate 113. The outer diameter of the outer end of the matching column 114 is larger than the outer diameter of the main body thereof. Correspondingly, a sliding groove matched with the outer end of the matching column 114 is provided on the cover plate 112, so that the cover plate 112 can be pushed into and assembled on the main shell 111 from the lower end of the main shell 111 through the cooperation between the matching column 114 and the groove body, and finally covers the inner side of the main shell 111, hides the components inside the main shell 111, and can be used as a decorative sheet.

[0045] As an alternative, the fixing plate is provided with a groove for fitting the main body part of the fitting post 114.

[0046] In this embodiment, a through hole 121 is formed in the middle of the handle base 12, and the clutch bracket 2 is inserted through the through hole 121. As one of the implementation manners, the through hole 121 is a circular hole, and the outer shape of the corresponding part of the clutch bracket 2 is also circular, so that the clutch bracket 2 can rotate and act in the through hole 121.

[0047] After the clutch bracket 2 is assembled in the through hole 121, a fitting ring 21 is installed at the outer end of the clutch bracket 2. Correspondingly, a torsion spring 22 that cooperates with the fitting ring 21 is installed at the outer end of the handle base 12. When the user presses down to unlock, the fitting ring 21 can drive the torsion spring 22 to deform. Thus, after the user releases the hand, the torsion spring 22 can drive the clutch bracket 2 and the handle 11 to reset.

[0048] As one of the implementation manners, an inner groove is formed at the outer end of the handle base 12, and both the torsion spring 22 and the fitting ring 21 are arranged in the inner groove to improve the space utilization rate.

[0049] Regarding the cooperation relationship between the fitting ring 21 and the torsion spring 22, in this embodiment, both left and right ends of the fitting ring 21 respectively include two extension arms 211, which respectively correspond to the two extension ends of the torsion spring 22.

[0050] Regarding the cooperation relationship between the fitting ring 21 and the clutch bracket 2, in this embodiment, the fitting ring 21 includes an extension head 212 extending inward. Correspondingly, a groove 23 that cooperates with the extension head 212 is formed at the outer end of the clutch bracket 2. The extension head 232 is clamped in the groove 23 so that the fitting ring 21 can rotate synchronously with the clutch bracket 2.

[0051] For the inner end of the clutch bracket 2, there is a sheet-like member 24 with an outer diameter larger than its main body part. The outer shell 111 of the handle 11 is sleeved on the inner end of the clutch bracket 2, and is specifically arranged between the sheet-like member 24 and the handle base 12, so that the sheet-like member 24 and the handle base 12 can limit the handle 11, so that the handle 11 and the clutch bracket 2 form a cooperation relationship and will not fall off, and can rotate relative to the handle base 12. At the same time, the inner end of the clutch bracket 2 is arranged inside the outer shell 111.

[0052] In this embodiment, a circular hole 115 adapted to the inner end of the clutch bracket 2 is formed in the outer shell 111 of the handle 11.

[0053] For the sheet-like member 24, a first fitting groove 241 is formed thereon. As one of the implementation manners, the first fitting groove 241 is in the form of an open groove.

[0054] In this embodiment, a first through hole 25 is formed in the clutch support 2. The first through hole 25 penetrates the clutch support 2 from the inner end to the outer end as a whole and includes a sheet-like member 24. The lock rod unit 3 is assembled at the first through hole 25. The lock rod unit 3 can also be called a linkage square shaft, and both it and the first through hole 25 can be square, so as to realize the synchronous rotation of the clutch support 2 and the lock rod unit 3. For the installation of the linkage square shaft and the lock body, and the installation with the outer handle, reference can be made to the existing design.

[0055] For the positioning piece 4, it is sleeved on the clutch support 2 and is configured to be laterally movable at the inner end of the handle seat 12. In this embodiment, the positioning piece 4 includes a second through hole 41 and a third mating groove 42. Among them, the inner end of the clutch support 2 passes through the second through hole 41 to realize the sleeving of the positioning piece 4.

[0056] As one implementation manner, the aperture of the second through hole 41 is larger than the outer diameter of the inner end of the clutch support 2. The shape of the second through hole 41 is square, and the shape of the inner end of the clutch support 2 is circular. At the same time, a plurality of cuts 26 for cooperating with the inner wall of the second through hole 41 are formed on the outer wall of the inner end of the clutch support 2. The cuts 26 are formed by opening at the outer wall of the inner end of the clutch support 2 so that the position where the cuts 26 are opened is a plane. One or two cuts can be opened.

[0057] In this embodiment, when the positioning piece 4 is laterally moved until the inner wall of the second through hole 41 enters the cut 26 or the inner wall of the second through hole 41 fits against the flat wall of the cut 26, under the action of the two flat walls, the clutch support 2 is limited and cannot rotate. Entering the cut 26 means that the inner wall of the second through hole 41 is on the movement path of the flat wall of the cut 26 when the clutch support 2 rotates. When the positioning piece 4 locks the clutch support 2, it is in the first state; when the positioning piece 4 does not lock the clutch support 2, it is in the second state.

[0058] In this embodiment, a plurality of limiting blocks 122 are arranged at the inner end of the handle seat 12. For example, corresponding limiting blocks 122 are respectively arranged at the upper and lower positions of its inner end, as Figure 12 shown. Correspondingly, limiting grooves 43 for cooperating with the limiting blocks 122 are formed on the positioning piece 4. For example, corresponding limiting grooves 43 are respectively formed at the upper and lower ends of it, as Figure 13 shown, to limit the lateral movement range of the positioning piece 4.

[0059] The toggle unit includes a positioning rod 61 and a paddle 62 disposed at the inner end of the positioning rod 61. In this embodiment, a mounting hole is provided at the inner end of the lock rod unit 3, and the positioning rod 61 is inserted through the mounting hole. Specifically, the outer end of the positioning rod 61 passes through the first through hole 25 and is inserted into the mounting hole to achieve the positioning of the toggle unit. As one embodiment, the mounting hole is circular in shape, and the main body of the positioning rod 61 is circular in shape. It is sufficient to ensure that the toggle unit can rotate without being affected by the mounting hole.

[0060] The toggle unit is specifically arranged in the handle 11, and the sheet member 24 of the clutch bracket 2 is arranged between the paddle 62 and the handle base 12. The paddle 62 includes a second matching groove 621 corresponding to the first matching groove 241 and a toggle pin 622 penetrating the third matching groove 42, wherein the toggle pin 622 cooperates with the third matching groove 42 to enable the positioning piece 4 to move laterally with the rotation of the toggle unit. Specifically, the third matching groove 42 includes a main section 421 and a lower section 422 inclined downward, such as Figure 13 As shown, the inner wall of the downwardly inclined lower section 422 is inclined toward the middle of the positioning piece 4. When the push pin 622 enters the lower section 422, the push pin 622 contacts its inner wall. During the circular motion of the push pin 622, it can push the positioning piece 4 to move laterally toward the clutch bracket 2, thereby driving the positioning piece 4 to the first state; and when the push pin 622 makes a circular motion in the opposite direction, the inner wall of the main section 421 is arranged to be inclined upward, so that the push pin 622 can push the positioning piece 4 to move laterally in the other direction, thereby driving the positioning piece 4 to the second state.

[0061] In this embodiment, the second mating groove 621 is similar in form to the first mating groove 241, but after installation, the second mating groove 621 does not completely overlap with the first mating groove 241, but only partially overlaps. The overlapping portion is used for the passage of the positioning pin 5, and the non-overlapping portion of the first mating groove 241 and the second mating groove 621 is required to ensure the movement of the positioning pin 5.

[0062] As one implementation manner, the overlapping portion of the first matching groove 241 and the second matching groove 621 is the right end of the first matching groove 241 and the left end of the second matching groove 621 .

[0063] In this embodiment, the positioning pin 5 is installed on the handle 11, such as being fixed on the fixed plate 113. When the handle 11 rotates, the positioning pin 5 moves accordingly. Because in the initial state, the positioning pin 5 is located at the right end of the first matching groove 241 and the left end of the second matching groove 621, when the handle 11 is lifted, the positioning pin 5 can drive the toggle unit to rotate counterclockwise, and the toggle pin 622 moves accordingly, driving the positioning piece 4 to the first state to lock the clutch bracket 2 and achieve the purpose of reverse locking. In this process, since there is space required for the positioning pin 5 to move to the left of the first matching groove 241, the clutch bracket 2 will not be driven to move at this time. If the clutch bracket 2 does not move, the locking rod unit 3 will not move, and there will be no problem that the locking rod unit 3 is restricted by the lock body and cannot rotate to that side.

[0064] When unlocking is required, the handle 11 is pressed down, and the positioning pin 5 first contacts the toggle unit, driving the toggle unit to rotate clockwise, so that the toggle pin 622 drives the positioning piece 4 to the second state, and then the positioning pin 5 contacts the inner wall of the first matching groove 241, driving the clutch bracket 2 and the locking rod unit 3 to rotate to unlock the lock.

[0065] In this embodiment, the handle 11 is provided with an arc groove 116 for the movement of the toggle pin 622 , and the handle 11 is provided with a hole 117 for installation or for the positioning pin 5 to pass through.

[0066] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
