Other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention.

Example 1

The embodiment discloses a locking mechanism, which comprises an elastic sheet 1 and a contact pin 2, wherein the surface of the elastic sheet 2 is provided with a broken pinhole 3, the pinhole 3 is a through hole penetrating through the elastic sheet, and a plurality of pits 4 are uniformly distributed on the contact pin 2 along the length direction; when in use, a pin 2 penetrates through the pin hole 3, and any one of the concave pits 4 is locked with the pin hole 3.

Preferably, the elastic sheet 2 of the present embodiment is of a non-planar configuration, i.e. the entire surface of the elastic sheet is not a horizontal plane.

In the locked state, as shown in fig. 2, the elastic sheet is deformed by applying a force to open the crack 5, so that the broken pin hole 3 is opened, and the pin 2 is pulled to unlock the pit 4 and the pin hole.

As a preferred embodiment of the pit 4, the present embodiment provides a variety of designs:

1. one type of recess is an annular groove formed radially along the pin, as shown in fig. 1-2;

2. the other pit is a continuous wave-shaped groove, and the section of a single pit is in a semicircular or arc-shaped concave structure. A row may be provided on the pins along the length direction, as shown in fig. 6; or multiple rows at different angles of the pins, a 2 row design is shown in fig. 5.

The elastic sheet 1 with the non-planar structure provided by the embodiment has at least one end which is upwarped, as shown in fig. 1-4, the two ends of the elastic sheet are upwarped, the whole elastic sheet is curved in an arc shape, a protruding part 7 is arranged on the upper surface of the elastic sheet, and the broken pinhole 3 is arranged on the protruding part 7. The bulge part 7 of the present embodiment is an arch bridge-shaped structure in a cut-off state, and the pinhole 3 is arranged in the middle of the arch bridge-shaped structure.

In one embodiment, the elastic sheet 1 is provided with a stopper portion 8. The fixing elastic sheet is convenient for fingers to hold or clamp other parts such as the shell to fix the direct position, and insertion and extraction of the contact pin are facilitated. The elastic sheet 1 is rectangular sheet, and one structure is that the middle part is provided with a limiting part 8 protruding outwards, as shown in figure 3; the other structure is that the middle part of the elastic sheet is provided with an inwards concave groove structure, as shown in figure 4.

Preferably, the plurality of concave pits 4 are arranged in the middle of the pin 2.

In the fixer of the embodiment, the bottom of the pin 2 is provided with a pressing disc 6 convenient for fingers to apply force. Except for the contact pin, most of other parts of the fixer can be made of plastic materials, so that the fixer is more portable and has lower cost.

As a preferred embodiment, the locking mechanism of the present product can be used for fixing articles made of soft materials, such as paper, cloth, plastics, etc., and can also be used in various scenes, such as fixing quilt covers and quilt cores, etc.

The locking mechanism uses the main working principle as follows:

the tip of the contact pin 2 penetrates through two objects to be fixed, such as a quilt cover and a quilt core, and continuously penetrates through a pinhole 3 in the middle of the spring plate 1, and under the elasticity of an arch bridge-shaped bulge part 7 of the spring plate 1, the pinhole 3 with the middle half-open tightly clamps a pit 4 designed on the contact pin 2, and at the moment, the contact pin 2 is in a clamping and locking state and cannot be pulled out from the lower part of the spring plate 3;

when the contact pin 2 needs to be taken out of the mechanism, the warped edges at two ends of the spring piece 1 are slowly pressed to be gradually flattened, meanwhile, the half-opened pin holes 3 in the arch bridge shape 7 positions on the spring piece 1 are in an elastic pulling state, and the pin holes 3 are completely separated from the pits 4 of the contact pin 2, so that the contact pin 2 can be easily taken out of the pit, and the separation of the contact pin and the spring piece is completed.

Example 2

Unlike embodiment 1, in the elastic piece having a non-planar structure of the present lock mechanism, a broken pinhole 3 is provided in the elastic piece 1, and a broken portion is a slit 5, as viewed from above as shown in fig. 7.

In one configuration, the elastic sheet is perforated with a plurality of broken pinholes, as shown in fig. 11.

This locking mechanism is through pressing down flexure strip 1, because atress deformation crack 5 enlarges and drives pinhole 3 and open, the contact pin can directly extract.

The length of the crack in this embodiment is preferably greater than or equal to 2 times the diameter of the pinhole.

The crack 5 of this embodiment can also set up to nonlinear line crack, and the crack that connects for two sections broken lines and pinhole edge as shown in fig. 13, and nonlinear line design more is favorable to driving crack one side to push down when pressing the flexure strip, and the opening angle is bigger relatively, and the pinhole is opened, extracts the contact pin of locking.

The above is the preferred embodiment of the present invention, and the protection scope of the present invention is not limited, and the deformation and improvement made by the design idea of the present invention for those skilled in the art should be considered as the protection scope of the present invention.
