When the operating element 12 is in the first state, the first stopping portion 112 is stopped between the second stopping portion 122 and the flip element 13 to limit the movement of the second stopping portion 122 toward the flip element 13, so as to limit the movement of the operating element 12 toward the flip element 13; when the operating element 12 is in the second state, the second blocking portion 122 moves away from the first blocking portion 112 toward the flip element 13, that is, the first blocking portion 112 moves away from the second blocking portion 122 toward the flip element 13, and the first blocking portion 112 releases the limitation on the second blocking portion 122, so that the second blocking portion 122 can move toward the flip element 13 under the action of an external force to implement the door opening operation.

Thus, by the cooperation of the first stopping portion 112 and the second stopping portion 122, the limitation and the release of the movement of the operating member 12 toward the flip member 13 by the fitting member 11 are realized, which is beneficial to simplify the cooperation between the fitting member 11 and the operating member 12.

Alternatively, in the example of fig. 6, 10, 13 and 14, the first pivot portion 111 is formed as a pivot hole, and the first stopper 112 may be disposed around the first pivot portion 111 so as to ensure that the first pivot portion 111 is formed as a circumferentially closed pivot hole and that the fit between the first pivot portion 111 and the second pivot portion 121 is reliable. Of course, the first pivot portion 111 may also be formed as a pivot shaft.

In some embodiments of the present invention, as shown in fig. 6 to 9 and 11, 13 and 14, an avoiding hole 112a for avoiding the other is formed on one of the first blocking portion 112 and the second blocking portion 122, and a protruding column is formed on the other of the first blocking portion 112 and the second blocking portion 122; when the operating element 12 is in the first state, the protruding columns and the avoiding holes 112a are arranged in a staggered manner, the second stopping portion 122 is limited on one side of the first stopping portion 112, which is far away from the turning piece 13, so that the operating element 12 cannot move towards the turning piece 13, when the operating element 12 is in the second state, the protruding columns and the avoiding holes 112a are arranged just opposite to each other, and the protruding columns can be inserted into the avoiding holes 112a under the action of external force, so that in the inserting and matching process, the operating element 12 moves towards the turning piece 13, and the first stopping portion 112 releases the stopping on the second stopping portion 122.

Therefore, the first blocking portion 112 can be stopped and released from the second blocking portion 122 by forming the avoiding hole 112a for avoiding the other one and forming the protruding column on the other one of the first blocking portion 112 and the second blocking portion 122, and the structure is simple and reliable.

For example, in the examples of fig. 6 to 9 and 11, 13 and 14, the avoiding hole 112a is formed on the first blocking portion 112, the second blocking portion 122 is formed with a protruding column, when the operating element 12 is in the first state, the protruding column and the avoiding hole 112a are arranged in a staggered manner along the circumferential direction of the first pivot portion 111, the protruding column abuts against a side of the first blocking portion 112 facing away from the flip 13 so that the operating element 12 cannot move towards the flip 13, when the operating element 12 is in the second state, the protruding column faces the avoiding hole 112a, at this time, a force moving towards the flip 13 can be applied to the operating element 12, and the protruding column is inserted into the avoiding hole 112a to allow the operating element 12 to move towards the flip 13. Of course, the avoiding hole 112a can also be formed on the second blocking portion 122, and the first blocking portion 112 is formed with a protruding pillar.

One or more avoidance holes 112a are provided; when the relief hole 112a is plural, the plural relief holes 112a may be provided at intervals in the circumferential direction of the first pivot portion 111. In the present application, "a plurality" means two or more.

Taking the example that the avoiding hole 112a is formed on the first blocking portion 112 and the second blocking portion 122 is formed with the protruding pillar as an example, a person skilled in the art can easily understand that the avoiding hole 112a is formed on the second blocking portion 122 after reading the following technical solutions. In the example of fig. 6 to 8, there are a plurality of avoiding holes 112a, there are a plurality of second stopping portions 122, each second stopping portion 122 is formed with a protruding column, each protruding column corresponds to one avoiding hole 112a, in the first state, each protruding column is disposed in a staggered manner with respect to the avoiding hole 112a, at this time, the plurality of protruding columns can all abut against the first stopping portion 112, so as to ensure that the operating element 12 is stably in the first state, in the second state, each protruding column is opposite to the corresponding avoiding hole 112a, and each protruding column is respectively inserted into the corresponding avoiding hole 112a under the action of external force, so as to ensure that the operating element 12 stably moves; of course, when there are a plurality of avoiding holes 112a, there may be one protruding column, and the protruding column may be inserted into any one of the avoiding holes 112a, or there may be one avoiding hole 112a and one protruding column.

In some embodiments of the present invention, as shown in fig. 6-9, the fitting member 11 further has a third stopping portion 113, the third stopping portion 113 is located on one side of the first stopping portion 112 away from the tilting member 13, and the third stopping portion 113 is used for limiting the rotation angle of the operating member 12 between the first state and the second state, so that the user can quickly and effectively sense whether the operating member 12 is switched to the second state in the process of rotating the operating member 12, and then apply the acting force on the operating member 12 toward the tilting member 13, thereby facilitating the improvement of the efficiency of the door opening operation of the user.

For example, when the operating element 12 is in the first state, the third stopping portion 113 may be in abutting engagement with the operating element 12 to limit the operating element 12 from continuing to rotate in a direction away from the second state; when the operating member 12 is in the second state, the third stopping portion 113 may be in abutting engagement with the operating member 12 to limit the operating member 12 from continuing to rotate in a direction away from the first state. Therefore, a user can conveniently know whether the operating piece 12 is switched to the first state or the second state through the operation hand feeling, and the operation convenience is improved.

In some embodiments of the present invention, as shown in fig. 6-9 and 11, 13 and 14, the second stopping portion 122 and the third stopping portion 113 are respectively formed as stopping protrusions, so that the second stopping portion 122 may protrude toward a direction close to the first stopping portion 112, the third stopping portion 113 may protrude toward a direction close to the operating element 12, and the protruding directions of the second stopping portion 122 and the third stopping portion 113 may be opposite.

The third stopping portion 113 and the second stopping portion 122 are disposed along the circumferential direction of the first pivoting portion 111 in a staggered manner, so that the third stopping portion 113 is used for limiting the rotation angle of the second stopping portion 122, and thus the rotation angle of the operating element 12 between the first state and the second state is limited, and the structure is simple and the processing is convenient.

For example, in the example of fig. 6 to 9 and 11, there are two third stopping portions 113, two third stopping portions 113 are rotationally symmetric about the pivot centers of the first pivot portion 111 and the second pivot portion 121, there are two second stopping portions 122, and two second stopping portions 122 and two third stopping portions 113 are alternately arranged one by one along the circumferential direction of the first pivot portion 111, so that each second stopping portion 122 rotates around the central axis of the first pivot portion 111 between the two third stopping portions 113 to realize the switching between the first state and the second state of the operating element 12, and meanwhile, during the rotation of the operating element 12, other components can apply acting force to the operating element 12 through the two second stopping portions 122 so as to ensure that the operating element 12 rotates smoothly; it can be seen that the corresponding central angle between the two third stopping portions 113 is the rotation angle of the operating element 12 between the first state and the second state, and the rotation angle may be 60 °, or 90 °, or 120 °, and so on.

Of course, the present application is not so limited; in other embodiments, there may be one third stopping portion 113 and one second stopping portion 122. It is understood that the number of the third stopping portions 113 and the second stopping portions 122 may be the same or different.

In some embodiments, as shown in fig. 6 to 9, the first blocking portion 112 is formed with at least one avoidance hole 112a, the avoidance hole 112a is used for avoiding the movement of the operating element 12 in the second state toward the flip element 13, and the avoidance hole 112a is formed at the edge of the third blocking portion 113, so that when the user senses that the operating element 12 rotates to the second state, the user can be informed that the second blocking portion 122 is aligned with the avoidance hole 112a, at this time, the operating element 12 can be directly pushed toward the flip element 13 without continuously rotating the operating element 12, so as to unlock the door lock structure 1, and further improve the operation convenience.

For example, in the examples of fig. 6 to 9 and 11, there are two third stopping portions 113, there are also two second stopping portions 122, the two second stopping portions 122 and the two third stopping portions 113 are alternately arranged one by one along the circumferential direction of the first pivot portion 111, each second stopping portion 122 corresponds to one avoidance hole 112a, and the avoidance holes 112a are located at the upstream side edge of the corresponding third stopping portion 113 in the direction from the first state toward the second state, so as to ensure that the two second stopping portions 122 are aligned with the corresponding avoidance holes 112a at the same time.

In some embodiments of the present invention, as shown in fig. 13 and 14, the third stopping portion 113 is formed as a stopping protrusion, and the third stopping portion 113 is used to limit the distance that the operating element 12 moves towards the flip 13 in the second state, so that the moving distance when the operating element 12 moves towards the flip 13 to stop against the third stopping portion 113 is enough to ensure that the operating element 12 pushes the flip 13 to rotate to the door opening position, so that the user can know whether the door lock structure 1 is unlocked through the operation hand feeling, and the operation convenience is further improved.

For example, in the example of fig. 13 and 14, the operating element 12 has a knob portion 123, a side of the knob portion 123 facing away from the flip 13 has a knob rib 123a, the user rotates the operating element 12 by rotating the knob rib 123a, and the user can also more intuitively know whether the operating element 12 rotates to the second state through the rotation change of the knob rib 123 a; for example, in the first state, the knob rib 123a is vertically arranged, and the user rotates the operating member 12 such that the knob rib 123a is horizontally arranged, and at this time, the operating member 12 is just switched to the second state, that is, the operating member 12 rotates 90 ° from the first state to the second state.
