Description
Technical Field
[0001] This invention relates to the field of lock technology, and in particular to eco-friendly door locks. Background Technology
[0002] Eco-friendly door locks are widely used due to their novel and beautiful designs, simple appearance, and ease of use. An eco-friendly door lock includes an inner handle rotatably mounted on an inner handle base, an outer handle rotatably mounted on an outer handle base, and a linkage shaft. One end of the linkage shaft is connected to the inner handle, and the other end is connected to the outer handle. The inner or outer handle is linked via the linkage shaft, which in turn causes the bolt of the lock body installed inside the door to extend or retract, thus opening the door.
[0003] For the deadbolt locking of eco-friendly door locks, existing technologies usually have an additional deadbolt button on the inner handle. Some lock by rotation, while others lock by tossing, as shown in published patent documents CN216043101U and CN218934173U. This structure is similar to the deadbolt knob of a general door lock. The deadbolt knob is rotated after the door is closed to achieve the deadbolt purpose.
[0004] Because the deadbolt button is relatively small, it is inconvenient to operate, and its inclusion affects the overall simplicity and aesthetics. Therefore, the applicant proposes to make improvements. Summary of the Invention
[0005] This invention addresses the shortcomings of existing technologies by providing an eco-friendly door lock. It allows for quick locking by lifting the handle and quick unlocking by pressing down the handle. Unlike common mechanical door locks, which are designed for small lock bodies and can only provide unidirectional rotation of the linkage axis, achieving upward locking is a challenge.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0007] Eco-friendly door locks, including
[0008] The handle unit includes a handle and a handle base;
[0009] A clutch bracket, which is rotatably mounted on the handle seat and moves synchronously with the handle, includes a first through hole and a first mating groove arranged at its inner end;
[0010] A locking rod unit is assembled at the first through hole and rotates synchronously with the clutch bracket;
[0011] A positioning piece, which is sleeved on the clutch bracket and laterally movable on the handle seat, includes a second through hole for the clutch bracket to pass through and a third mating groove. The positioning piece has a first state of locking the clutch bracket and a second state of unlocking the clutch bracket.
[0012] A toggle unit includes a positioning rod passing through the clutch bracket and / or the locking rod unit, and a paddle disposed at the inner end of the positioning rod. The paddle includes a second mating groove corresponding to the first mating groove and a toggle pin passing through the third mating groove.
[0013] A positioning pin is fixed to the handle and passes through the right end of the first mating groove and the left end of the second mating groove, so that the first mating groove and the second mating groove reserve the movement space of the positioning pin.
[0014] When the handle is raised, the positioning pin drives the actuating unit to rotate in the opposite direction, so that the actuating pin drives the positioning piece to the first state;
[0015] When the handle is pressed down, the positioning pin drives the actuating unit to rotate in the forward direction, so that the actuating pin drives the positioning piece to the second state, and then the positioning pin drives the clutch bracket and the locking rod unit to rotate to unlock the lock.
[0016] In the above scheme, preferably, the handle includes a main housing and a detachable cover plate mounted on the main housing, and the main housing is fitted onto the clutch bracket so that the inner end of the clutch bracket is arranged inside the main housing.
[0017] In the above scheme, preferably, a fixing plate is installed inside the main housing, and the positioning pin is fixed to the fixing plate;
[0018] The main housing or the fixing plate is provided with a plurality of mating posts, and the cover plate is provided with a sliding groove that matches the outer end of the mating posts.
[0019] In the above scheme, preferably, a mating ring is installed at the outer end of the clutch bracket, and a torsion spring that mates with the mating ring is installed on the handle seat to reset the clutch bracket and the handle.
[0020] In the above scheme, preferably, the outer wall of the inner end of the clutch bracket is provided with a plurality of slits for cooperating with the inner wall of the second through hole. When the inner wall of the second through hole enters the slit, the clutch bracket is limited by the positioning piece.
[0021] In the above scheme, preferably, the diameter of the second through hole is larger than the outer diameter of the inner end of the clutch bracket, the shape of the second through hole is square, and the shape of the inner end of the clutch bracket is circular.
[0022] In the above scheme, preferably, the inner end of the handle seat is provided with a plurality of limiting blocks, and the positioning piece is provided with a limiting groove that cooperates with the limiting blocks.
[0023] In the above scheme, preferably, the paddle is arranged inside the handle, and the handle is provided with an arc-shaped groove for the movement of the paddle pin.
[0024] In the above scheme, preferably, the handle has a hole for installation or for the positioning pin to pass through.
[0025] In the above scheme, preferably, the third mating groove includes a main section and a downwardly inclined lower section. When the actuating pin enters the lower section, the positioning piece is driven to a first state; when the actuating pin enters the main section, the positioning piece is driven to a second state.
[0026] The beneficial effects of this invention are:
[0027] This invention enables quick locking by lifting the handle. Lifting causes the actuating unit to rotate via a positioning pin, which in turn locks the clutch bracket by engaging the positioning plate, preventing rotation and achieving locking. Pressing down unlocks the handle. Pressing down causes the actuating unit to rotate in the opposite direction via the positioning pin, which in turn unlocks the clutch bracket by engaging the positioning plate. Further pressing down causes the lock rod to extend and retract the lock tongue, opening the door. The design is simple, easy to operate, and aesthetically pleasing. Attached Figure Description

[0041] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
[0042] See Figures 1-13 The eco-friendly door lock includes a handle unit, a clutch bracket 2, a lock rod unit 3, a positioning plate 4, a toggle unit, and a positioning pin 5.
[0043] The handle unit includes a handle 11 and a handle base 12. The handle base 12 is fixedly installed on the door, and the handle 11 can rotate relative to the handle base 12, including at least upward rotation (lifting) and downward rotation (pressing). The specific installation and positioning of the handle 11 is related to the clutch bracket 2, as detailed below. The design of this application mainly targets the inner handle; the outer handle is the same as the existing design and can be locked and unlocked using fingerprint or keyhole methods.
[0044] In this embodiment, the handle 11 includes a main housing 111 and a detachable cover plate 112 mounted on the main housing 111. A fixing plate 113 is installed inside the main housing 111. A plurality of mating posts 114 are installed on the main housing 111 or the fixing plate 113. The outer diameter of the outer end of the mating post 114 is larger than the outer diameter of its main body. Correspondingly, a sliding groove adapted to the outer end of the mating post 114 is provided on the cover plate 112. Thus, the cover plate 112 can be pushed into the main housing 111 from the lower end of the main housing 111 and assembled on the main housing 111 through the cooperation of the mating post 114 and the groove, and finally cover the inner side of the main housing 111, hide the components inside the main housing 111, and can be used as a decorative piece.
[0045] As one option, the fixing plate has a groove for the main body of the mating column 114.
[0046] In this embodiment, a through hole 121 is provided in the middle of the handle seat 12, and the clutch bracket 2 is inserted through the through hole 121. As one embodiment, the through hole 121 is a circular hole, and the corresponding part of the clutch bracket 2 is also circular in shape, so that the clutch bracket 2 can rotate within the through hole 121.
[0047] After the clutch bracket 2 is assembled into the through hole 121, a mating ring 21 is installed on the outer end of the clutch bracket 2. Correspondingly, a torsion spring 22 that mates with the mating ring 21 is installed on the outer end of the handle seat 12. When the user presses down to unlock, the mating ring 21 can drive the torsion spring 22 to deform. Thus, after the user releases the handle, the clutch bracket 2 and the handle 11 can be reset by relying on the torsion spring 22.
[0048] In one embodiment, an inner groove is provided on the outer end of the handle seat 12, and the torsion spring 22 and the mating ring 21 are arranged in the inner groove to improve space utilization.
[0049] Regarding the mating relationship between the mating ring 21 and the torsion spring 22, in this embodiment, the left and right ends of the mating ring 21 each include two extension arms 211, which correspond to the two extension ends of the torsion spring 22 respectively.
[0050] Regarding the mating relationship between the mating ring 21 and the clutch bracket 2, in this embodiment, the mating ring 21 includes an inwardly extending head 212. Correspondingly, the outer end of the clutch bracket 2 is provided with a groove 23 that mates with the extension head 212. The extension head 232 is engaged in the groove 23 so that the mating ring 21 can rotate synchronously with the clutch bracket 2.
[0051] The inner end of the clutch bracket 2 has a sheet-like member 24 with an outer diameter larger than that of its main body. The outer shell 111 of the handle 11 is fitted into the inner end of the clutch bracket 2, specifically arranged between the sheet-like member 24 and the handle seat 12, so that the sheet-like member 24 and the handle seat 12 can limit the handle 11, so that the handle 11 and the clutch bracket 2 form a cooperative relationship and will not fall off, and can rotate relative to the handle seat 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 provided on the outer shell 111 of the handle 11.
[0053] For the sheet-like member 24, a first mating groove 241 is provided on it. In one embodiment, the first mating groove 241 is an open groove.
[0054] In this embodiment, the clutch bracket 2 has a first through hole 25, which extends from the inner end to the outer end of the clutch bracket 2 and includes a sheet-like component 24. The locking rod unit 3 is assembled at the first through hole 25. The locking rod unit 3 can also be called a linkage square shaft, and both it and the first through hole 25 can be square, thereby achieving synchronous rotation of the clutch bracket 2 and the locking rod unit 3. The installation of the linkage square shaft with the lock body and with the outer handle can refer to existing designs.
[0055] The positioning piece 4 is fitted onto the clutch bracket 2 and is 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. The inner end of the clutch bracket 2 passes through the second through hole 41 to realize the fitting of the positioning piece 4.
[0056] In one embodiment, the diameter of the second through hole 41 is larger than the outer diameter of the inner end of the clutch bracket 2. The shape of the second through hole 41 is square, and the shape of the inner end of the clutch bracket 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 provided on the outer wall of the inner end of the clutch bracket 2. The cuts 26 are formed by opening at the outer wall of the inner end of the clutch bracket 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 moves laterally to the inner wall of the second through hole 41 and enters the cut 26, or when the inner wall of the second through hole 41 is attached to the planar wall of the cut 26, the clutch bracket 2 is limited and cannot rotate under the action of the two flat walls. Entering the cut 26 means that the inner wall of the second through hole 41 is located on the movement path of the planar wall of the cut 26 when the clutch bracket 2 rotates. When the positioning piece 4 locks the clutch bracket 2, it is in the first state; when the positioning piece 4 does not lock the clutch bracket 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 base 12. For example, corresponding limiting blocks 122 are respectively set at the upper and lower ends of its inner end. Figure 12 As shown. Correspondingly, the positioning piece 4 is provided with a limiting groove 43 that cooperates with the limiting block 122. For example, corresponding limiting grooves 43 are provided at its upper and lower ends respectively. Figure 13 As shown, this limits the lateral range of motion of the positioning piece 4.
[0059] The actuating unit includes a positioning rod 61 and a paddle 62 disposed at the inner end of the positioning rod 61. In this embodiment, the inner end of the locking rod unit 3 has a mounting hole, and the positioning rod 61 passes 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 positioning of the actuating unit. As one embodiment, the mounting hole is circular in shape, and the main body of the positioning rod 61 is circular in shape, as long as it can ensure that the actuating unit can rotate without being affected by the mounting hole.
[0060] The actuating unit is specifically arranged inside the handle 11. The plate-like component 24 of the clutch bracket 2 is arranged between the actuating plate 62 and the handle seat 12. The actuating plate 62 includes a second mating groove 621 corresponding to the first mating groove 241 and an actuating pin 622 passing through the third mating groove 42. The engagement of the actuating pin 622 with the third mating groove 42 enables the positioning piece 4 to move laterally as the actuating unit rotates. Specifically, the third mating groove 42 includes a main section 421 and a downwardly inclined lower section 422, such as... Figure 13 As shown, the inner wall of the downward-sloping lower section 422 is inclined towards the middle of the positioning piece 4. When the actuating pin 622 enters the lower section 422, the actuating pin 622 contacts its inner wall. During the circular motion of the actuating pin 622, it can push the positioning piece 4 to move laterally towards the clutch bracket 2, thereby driving the positioning piece 4 to the first state. When the actuating pin 622 moves in the opposite direction, the inner wall of its main section 421 is arranged to be inclined upward, so that the actuating pin 622 can push the positioning piece 4 to move laterally in another 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 and the first mating groove 241 do not completely overlap. They only partially overlap, and the overlapping part is used for the positioning pin 5 to pass through. The non-overlapping part of the first mating groove 241 and the second mating groove 621 needs to ensure the movement of the positioning pin 5.
[0062] In one embodiment, the overlapping portion of the first mating groove 241 and the second mating groove 621 is the right end of the first mating groove 241 and the left end of the second mating groove 621.
[0063] In this embodiment, the positioning pin 5 is installed on the handle 11, such as fixed on the fixing plate 113. When the handle 11 rotates, the positioning pin 5 moves accordingly. Since the positioning pin 5 is located at the right end of the first mating groove 241 and the left end of the second mating groove 621 in the initial state, when the handle 11 is lifted, the positioning pin 5 can drive the actuating unit to rotate counterclockwise. The actuating pin 622 moves accordingly, driving the positioning piece 4 to the first state to lock the clutch bracket 2 and achieve the purpose of anti-locking. During this process, since there is space for the positioning pin 5 to move to the left of the first mating groove 241, the clutch bracket 2 will not be driven to move. If the clutch bracket 2 does not move, the locking rod unit 3 will not move, so there will be no problem that the locking rod unit 3 is restricted by the lock body and cannot rotate in that direction.
[0064] When unlocking is required, press down the handle 11. The positioning pin 5 first contacts the toggle unit, causing the toggle unit to rotate clockwise, so that the toggle pin 622 drives the positioning piece 4 to the second state. Then the positioning pin 5 contacts the inner wall of the first mating groove 241, causing 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-shaped groove 116 for the movement of the actuating 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, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
