Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the safety locking technology of children's appliances, in particular to a two-way locking mechanism for children's appliances such as strollers. BACKGROUND
[0002] The existing children's appliances, such as strollers, usually adopt a single locking mechanism to ensure the safety of children. However, the single locking mechanism may have safety risks in some cases, and it is easy to be accidentally unlocked due to accidental touch, so the safety needs to be improved. SUMMARY
[0003] The purpose of the present application is to provide a two-way locking mechanism, which realizes safe unlocking and effectively prevents accidental unlocking by the double operation design of the unlocking member and the rotating handle, and the linkage of the sliding member and the linkage member driven by the inclined surface, the locking assembly.
[0004] The technical solution of the present application is a two-way locking mechanism, which comprises a connecting pipe, a locking assembly arranged at the side end of the connecting pipe and capable of being controlled by unlocking movement to control locking or not, and a rotating handle. The connecting pipe is provided with a mounting seat, and the mounting seat is provided with a sliding member capable of sliding relative to the mounting seat. The sliding member is connected with the locking assembly through a linkage member. The rotating handle is rotatably installed on the mounting seat and is matched with the sliding member through an inclined surface, so as to drive the sliding member to slide when the rotating handle rotates, thereby driving the locking assembly to perform unlocking operation. The two-way locking mechanism further comprises an unlocking member capable of controlling whether the rotating handle can rotate.
[0005] One of the further technical solutions is that the unlocking member is installed on the rotating handle and can move relative to the rotating handle. When the rotating handle is in the locked position, the unlocking member blocks the mounting seat to prevent the rotating handle from rotating to realize unlocking. After the unlocking member is unlocked, the unlocking member removes the blocking of the mounting seat, and at this time the rotating handle can rotate relative to the mounting seat. The movement mode of the unlocking member relative to the rotating handle is sliding expansion. The unlocking member is an elastic button.
[0006] The second of the further technical solutions is that the unlocking member is installed on the mounting seat and can move relative to the mounting seat. When the rotating handle is in the locked position, the unlocking member blocks the rotating handle or the sliding member to prevent the rotating handle from rotating to realize unlocking. After the unlocking member is unlocked, the unlocking member removes the blocking of the rotating handle or the sliding member, and at this time the rotating handle can rotate relative to the mounting seat.
[0007] As a preferred technical solution, the sliding member has a first inclined surface, and the rotating handle has a second inclined surface matched with the corresponding first inclined surface.
[0008] As a preferred technical solution, the dual-lock mechanism also includes a reset component for automatic reset after the handle is unlocked.
[0009] As a preferred technical solution, the linkage component is a traction cable.
[0010] Compared with the prior art, this application has the following advantages: This application achieves safe unlocking by using a dual operation design of unlocking component and rotating handle, combined with the linkage of inclined plane driven sliding component, linkage component and locking component, effectively preventing accidental unlocking and improving safety performance.

[0035] Embodiment one: as Figures 1 to 15As shown, a two-way lock mechanism includes a connecting pipe 1, locking assemblies arranged on both sides of the connecting pipe 1 and capable of being controlled by an unlocking movement to control locking or not, and a rotating handle 2, a middle part of the connecting pipe 1 is provided with a mounting seat 3, both sides of the mounting seat 3 are respectively provided with sliding members 4 capable of sliding relative to the mounting seat 3, both sides of the sliding members 4 are respectively connected with the locking assemblies on both sides through linkage members 5; the rotating handle 2 is rotatably installed on the mounting seat 3 and is matched with the sliding members 4 through inclined surfaces, so that the sliding members 4 are driven to slide and the locking assemblies are driven to perform unlocking operation when the rotating handle 2 is rotated; the two-way lock mechanism further includes an unlocking member 6 capable of controlling whether the rotating handle 2 can rotate.
[0036] In the embodiment, the unlocking member is installed on the rotating handle and is capable of moving relative to the rotating handle. The movement mode of the unlocking member 6 relative to the rotating handle 2 is preferably sliding expansion and contraction, when the rotating handle 2 is in a locked position, the unlocking member 6 is extended and blocks the mounting seat 3, preventing the rotating handle 2 from being rotated upward to realize unlocking; after the unlocking member 6 is pressed, the unlocking member 6 is retracted into the rotating handle 2, the blocking of the mounting seat 3 is released, and at this time, the rotating handle 2 can be rotated relative to the mounting seat 3.
[0037] In the embodiment, the unlocking member 6 is preferably an elastic button, a self-resetting spring is built in the button, and the mounting seat 3 needs to be continuously pressed to release the locking, preventing vibration from being mispressed.
[0038] In the embodiment, the sliding member 4 has a first inclined surface 401, the first inclined surfaces 401 on both sides of the sliding member 4 are symmetrically arranged and are inclined surfaces with high inner part and low outer part; the rotating handle 2 has second inclined surfaces 201 on both sides, the second inclined surfaces 201 are matched with the corresponding first inclined surfaces 401 and are inclined surfaces with high inner part and low outer part. Preferably, the rotating handle 2 has protrusions 202 corresponding to the sliding members 4 on both sides, and the second inclined surfaces 201 are formed on the corresponding protrusions 202. The application adopts a double-inclined-surface transmission design, reduces the demand for single-point operation force, and improves the unlocking stability; the mechanical linkage structure is not only simple and reliable, but also labor-saving and accurate.
[0039] In the embodiment, the two-way lock mechanism further includes a reset member (not shown in the figure) for automatic resetting of the rotating handle 2 after unlocking. The reset member can be arranged between the rotating handle 2 and the mounting seat 3, between the sliding member 4 and the mounting seat 3, or between the locking assembly and the fixed component (such as the connecting pipe), for directly resetting the rotating handle 2 to the locked position under the resetting action of the reset member or indirectly resetting the rotating handle 2 to the locked position under the driving of the inclined surface of the sliding member 4 after unlocking, to realize automatic resetting. The reset member can be a torsional spring (between the rotating handle 2 and the mounting seat 3) or a compression spring (between the sliding member 4 and the mounting seat 3 or between the locking assembly and the fixed component).
[0040] In the embodiment, the linkage member 5 is preferably a traction cable.
[0041] The working principle of the utility model is as follows:
[0042] In the locked state, the unlocking piece 6 blocks the mounting seat 3, at this time, the rotating handle 2 cannot be rotated upward to realize unlocking, and the locking assembly remains locked.
[0043] When unlocking, first press the unlocking piece 6 to release the locking of the rotating handle 2 (release the first locking), and then rotate the rotating handle 2 upward, under the cooperation of the inclined surface, the sliding piece 4 will slide to the middle, thereby driving the linkage piece 5 (the traction cable) to pull the locking assembly to realize unlocking (realize the second unlocking).
[0044] After loosening the rotating handle 2, the rotating handle 2 is automatically reset under the action of the reset piece. When the rotating handle 2 is reset to the locked position, the unlocking piece 6 is automatically ejected and reset, realizing the automatic locking of the rotating handle 2.
[0045] Embodiment two: the difference between the embodiment two and the embodiment one is that the unlocking piece 6 is installed on the mounting seat 3 and can move relative to the mounting seat 3, and can be used to block the rotation of the rotating handle 2.
[0046] When the rotating handle 2 is in the locked position, the unlocking piece 6 blocks the rotating handle 2 to prevent the rotating handle 2 from rotating to realize unlocking; after unlocking operation is performed on the unlocking piece 6, the unlocking piece 6 releases the blocking of the rotating handle 2, at this time, the rotating handle 2 can rotate relative to the mounting seat 3.
[0047] Embodiment three: the difference between the embodiment three and the embodiment one is that the unlocking piece 6 is installed on the mounting seat 3 and can move relative to the mounting seat 3, and can be used to block the rotation of the sliding piece 4.
[0048] When the rotating handle 2 is in the locked position, the unlocking piece 6 blocks the sliding piece 4 to prevent the rotating handle 2 from rotating to realize unlocking; after unlocking operation is performed on the unlocking piece 6, the unlocking piece 6 releases the blocking of the sliding piece 4, at this time, the rotating handle 2 can rotate relative to the mounting seat 3.
[0049] The application realizes safe unlocking by the double operation design of the unlocking piece 6 and the rotating handle 2, and the linkage of the sliding piece 4 and the linkage piece 5, the locking assembly driven by the inclined surface, effectively prevents accidental unlocking, and improves the safety performance. The mechanism is compact in structure and convenient to operate, and is particularly suitable for the field of children's strollers and other fields requiring high safety.
[0050] As used in the description of the application herein, the terms "preferably," "more preferably," "most preferably," and the like are used to describe a preference of one embodiment over another. Uniform use of these terms throughout the description does not require uniform or identical embodiments.
[0051] The above examples are merely intended for the purpose of illustration of the detailed schemes of the present application. The present application is not limited to the above detailed schemes, i.e. it does not mean that the present application must rely on the above detailed schemes to be implemented. It should be understood by those skilled in the art that any improvement of the present application, equivalent replacement of each raw material of the product of the present application, addition of auxiliary ingredients, selection of specific modes, etc. all fall within the protection scope and disclosure scope of the present application.
