Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
In order to simplify pressing mechanism while realizing that locking or unlock operate by pressing operation, reduce amount of parts,
Ease of assembly, as shown in Figures 1 to 10, the present embodiment propose a kind of pressing mechanism, including pressing piece 10, matching piece 20 and
The dynamic clamping head and quiet clamping head 30 being formed between pressing piece 10, matching piece 20.
It is formed with vertical its on pressing piece 10 and presses locking bolt 11 that direction extends, and is formed with and locking bolt in matching piece 20
The guide groove A of 11 inserting cooperations, when implementing to press to pressing piece 10, guide groove A is used to limit, guide the moving rail of locking bolt 11
Mark comprising in the pressing section of angle setting, reset section, pressing section, reset section all have multiple and be staggeredly connected.To pressing
When part 10 is implemented to press, locking bolt 11, which is driven and is close to its under the guiding of pressing section, carries out spiral movement, due to pressing section, again
Position section is staggeredly connected, and locking bolt 11 gradually moves close to the reset section adjacent with the pressing section where it, where locking bolt 11 reaches
After pressing section and corner between the reset section, pressing in place, releases pressing at this time, and the elasticity of dynamic clamping head and quiet clamping head 30 is restored
Power drives locking bolt 11 mobile, and locking bolt 11 is accurately held out against in the reset section.
In order to realize the dismounting between pressing piece 10, matching piece 20 by pressing operation, to apply in cup lid structure, bottle
When lid structure etc. presses on switching mechanism, the present embodiment is formed with the opening passed in and out for locking bolt 11 at the both ends of guide groove A, is locking
Bolt 11 across opening realize and guide groove A separation or inserting while just realize tearing open pressing piece 10, matching piece 20
Dress.Certainly, it can also be formed along the flexible locking bolt 11 in direction is pressed perpendicular to it, be passed through on pressing piece 10 in other embodiments
The stretching of locking bolt 11 is realized to be inserted between locking bolt 11 and guide groove A, by the retraction of locking bolt 11 realize locking bolt 11 and guide groove A it
Between separation, under this scheme, pressing mechanism be can be applied in other push switch mechanisms.
Specifically, the opening at the both ends the present embodiment guide groove A is respectively communicated with pressing section, reset section, and the shape on guide groove A
At 2 pressing sections, 2 reset sections, as shown in figure 3,2 pressing sections are respectively the first pressing section A1, the second pressing section A2,2
A reset section is respectively the first reset section A3, the second reset section A4, wherein is opened first pressing connection one end guide groove A section A1
Mouthful, the second reset section A4 is connected to the opening of the guide groove A other end.
After by the opening of the alignment of locking bolt 11 the first pressing of connection section A1, pressing piece 10 is implemented to press, locking bolt 11 passes through
Opening enters the first pressing section A1 and moves along the first pressing section A1 spiral, presses section A1, the first reset section A3 in arrival first
Between corner after, pressing in place, as shown in Figure 4, Figure 5, release pressing when, dynamic clamping head and quiet clamping head 30 drive locking bolt 11 be moved to
On first reset section A3, and the corner between the first reset section A3, the second pressing section A2 is finally held out against, so far realizes pressing
Assembling between part 10, matching piece 20 realizes locking, as shown in Figure 6, Figure 7.When being pressed again, 11 spiral of locking bolt
It is moved to the second pressing section A2, after pressing in place again, as shown in Figure 8, Figure 9, and after releasing pressing at this time, dynamic clamping head and quiet clamping head 30
Locking bolt 11 is driven to be moved to the second reset section A4, locking bolt 11 finally can be detached from guiding along the opening of the second reset section A4 of connection
Slot A realizes unlock, as shown in Figure 10 to realize the disassembly between pressing piece 10, matching piece 20.
As shown in Figure 2 and Figure 3, the present embodiment matching piece 20 includes annular sidewall 21, specifically in the inside shape of annular sidewall 21
The two tooth sections (22,23) being oppositely arranged at geared surface, the tooth socket of two tooth sections (22,23) offset one from another, and utilize two tooth sections
The flank of tooth of (22,23) limits guide groove A, in order to realize unidirectional movement of the locking bolt 11 in guide groove A, it is ensured that be pressed into
When position, releasing pressing, dynamic clamping head and quiet clamping head 30 is able to drive locking bolt 11 and is moved to reset section, and two tooth sections (22,23) are ratchet
Section.
In order to be adapted to above-mentioned matching piece 20, the present embodiment pressing piece 10 is the lid that can be partially accommodated in annular sidewall 21
Body.In order to improve the reliability assembled between pressing piece 10, matching piece 20, specifically it is disposed on pressing piece 10 and is distributed in pairs
Locking bolt 11, each pair of locking bolt 11 is located at the opposite sides of pressing piece 10, corresponding, and difference is limited on the inside of annular sidewall 21
The guide groove A being distributed positioned at 20 opposite sides of matching piece and in pairs, the reliability for ensuring to assemble by realizing symmetrical connection.
When in order to separate between pressing piece 10, matching piece 20, dynamic clamping head and quiet clamping head 30 is avoided to fall, lose, this is practical new
Preferably dynamic clamping head and quiet clamping head 30 is mounted on pressing piece 10 or matching piece 20 in type embodiment.Specifically, the present embodiment will be elastic
Return unit 30 is installed on pressing piece 10, as shown in figure 3, the side of relative engagement part 20 is formed with clamping and matches on pressing piece 10
The card slot 12 of dynamic clamping head and quiet clamping head 30 is closed, and is cooperated as dynamic clamping head and quiet clamping head 30 in locking bolt 11 and guide groove A inserting using spring
When, elastic spacing one is resisted against between pressing piece 10, matching piece 20 to provide elastic restoring force, for this purpose, can be in pressing piece 10
The inside of annular sidewall 21 is formed with the support plate 24 extended towards middle part, is used to dynamic clamping head and quiet clamping head 30 against cooperation.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
Invention is explained in detail, those skilled in the art should understand that: it still can be to aforementioned each implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features；And these modification or
Replacement, the spirit and scope for technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution.
