In addition, the terms "first", "second", "third" and the like are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0039] Embodiment one

[0040] As shown in the drawings, the semi-automatic pressing type locking structure in the present embodiment includes a shell 1, a pressing displacement mechanism, a locking structure, and a locked piece 3. Figures 1 to 5 Among them, the inner cavity of the shell 1 is cylindrical, the outer shape of the shell 1 can be cylindrical or other shapes, an end port 13 is formed at one end of the shell 1, and the end port 13 is used for the locked piece 3 to pass into the shell 1 and be locked by the locking structure.

[0041] The locked piece 3 includes a body 3-1 and a clamping portion 3-2 at the end of the body 3-1, the diameter of the clamping portion 3-2 is greater than the diameter of the body 3-1, a step structure is formed at the connection between the clamping portion 3-2 and the body 3-1, and the clamping portion 3-2 of the locked piece 3 enters the shell 1 from the end port 13 of the shell 1, and the clamping portion 3-2 is locked or unlocked by the locking structure.

[0042] The locking and unlocking of the locked piece 3 are realized by the cooperation of the pressing displacement mechanism and the locking structure.

[0043] The pressing displacement mechanism includes a rotating sliding piece 2 and an elastic piece 4, etc., the rotating sliding piece 2 is located in the inner cavity of the shell 1, and the rotating sliding piece 2 can slide along the axial direction of the inner cavity of the shell 1 and rotate around the axis of the inner cavity of the shell 1.

[0044]

[0045] ​The locking structure comprises a slot 9 arranged on the rotating sliding member 2, the slot 9 is coaxial with the rotating sliding member 2, and the slot 9 is located on the rotating sliding member 2 close to one end of the port 13 of the shell 1. In operation, the locking member 3 enters the shell 1 from the port 13, and the clamping portion 3-2 of the locking member 3 is inserted into the slot 9. The diameter of the clamping portion 3-2 of the locking member 3 is slightly smaller than the diameter of the inner wall of the slot 9, so that it can be inserted into the slot 9. A plurality of mounting holes 10 are uniformly distributed on the side wall of the slot 9, and one locking member 11 is arranged in each mounting hole 10. The length of the mounting hole 10 is smaller than the length or diameter of the locking member 11, so that a part of the locking member 11 is exposed from the inner end or outer end of the mounting hole 10. Meanwhile, a retreat groove 12 is formed on the inner wall of the shell 1.

[0046] When the rotating sliding member 2 moves to enable the outer end of the locking member 11 to enter the retreat groove 12, the clamping portion 3-2 of the locking member 3 is inserted into the slot 9 and passes through the locking member 11, which is pressed to move outward into the retreat groove 12. The locking member 11 cannot block the locking member 3 from being inserted into or separated from the slot 9, and at this time, the device is in an unlocked state. When the rotating sliding member 2 moves to separate the locking member 11 from the retreat groove 12, the inner end of the locking member 11 enters the slot 9 under the pressing action of the inner wall of the shell 1. The distance between the locking member 11 and the bottom surface of the slot 9 is slightly greater than the length of the clamping portion 3-2 of the locking member 3. At this time, the locking member 11 is clamped on the outer side of the clamping portion 3-2, which can prevent the locking member 3 from being separated from the slot 9, and at this time, the device is in a locked state.

[0047] The elastic member 4 is located at the end of the rotating sliding member 2 away from the port 13 of the shell 1. Under the action of the elastic member 4, the rotating sliding member 2 has a tendency to move towards the port 13 of the shell 1. The above-mentioned unlocked state and locked state are realized by two limit positions of the rotating sliding member 2, and the two limit positions are limited by the cooperation of the limiting teeth 7 on the inner wall of the shell 1 and the guide teeth 8 on the outer wall of the rotating sliding member 2.

[0048] The limiting teeth 7 are uniformly distributed around the axis of the inner cavity of the shell 1, and specifically include two continuous inclined sawtooth surfaces located at the end away from the port 13 of the shell 1. The guide teeth 8 are the same in number as the limiting teeth 7 and are uniformly distributed around the outer wall of the rotating sliding member 2. The end of the guide teeth 8 is an inclined surface located at the end close to the port 13 of the shell 1. The inclined sawtooth surfaces of the limiting teeth 7 and the inclined surfaces of the guide teeth 8 have the same inclination direction, and a sliding channel 15 capable of accommodating the guide teeth 8 is formed between the adjacent two limiting teeth 7.

[0049] When the inclined surface of the guide tooth 8 contacts the first inclined sawtooth surface of the limiting tooth 7, the guide tooth 8 enters the groove formed by the two continuous inclined sawtooth surfaces under the action of the elastic member 4. At the same time, the rotating sliding member 2 rotates at a certain angle. At this time, the limiting tooth 7 restricts the guide tooth 8 and the rotating sliding member 2 from approaching the port 13 of the housing 1. This is the first extreme position of the rotating sliding member 2, corresponding to the locking state.

[0050] When the inclined surface of the guide tooth 8 contacts the second inclined sawtooth surface of the limiting tooth 7, the guide tooth 8 moves along the inclined sawtooth surface under the action of the elastic member 4 until it enters the sliding channel 15. At the same time, the rotating sliding member 2 rotates at a certain angle. At this time, the limiting tooth 7 can no longer restrict the guide tooth 8 and the rotating sliding member 2 from approaching the port 13 of the housing 1. The rotating sliding member 2 approaches the port 13 of the housing 1 until the end of the rotating sliding member 2 contacts the inner end face of the housing 1. This is the second limit position of the rotating sliding member 2, which corresponds to the unlocked state.

[0051] The guide teeth 8 of the rotating slider contact the different inclined sawtooth surfaces of the limiting member, ultimately forming the two different states mentioned above. This contact is achieved through the rotation of the rotating slider. To achieve the rotation of the rotating sliding member 2, a driving member 17 is provided at the end of the housing 1 furthest from port 13. First rotating driving teeth 5 are circumferentially distributed at the end of the driving member 17. An axial groove 16 is formed on the inner wall of the housing 1, and a slider is provided on the outer wall of the driving member 17, slidingly connected to the groove 16. A baffle for contacting the elastic member 4 is provided on the driving member 17. A ring of second rotating driving teeth 6 is provided at the end of the rotating sliding member 2 furthest from port 13 of the housing 1. The number and size of the first rotating driving teeth 5 and the second rotating driving teeth 6 are the same.

[0052] When the guide tooth 8 is located in the groove formed by two consecutive inclined sawtooth surfaces or when the guide tooth 8 is located in the sliding channel 15, the first rotary drive tooth 5 and the second rotary drive tooth 6 are offset by a small distance from each other, so that the first rotary drive tooth 5 and the second rotary drive tooth 6 are roughly corresponding to each other. However, when the second rotary drive tooth 6 approaches and contacts the first rotary drive tooth 5, the inclined tooth surfaces of the first rotary drive tooth 5 and the second rotary drive tooth 6 contact each other and drive the rotary sliding member 2 to rotate a certain angle under pressure. After rotating a certain angle, the rotary sliding member 2 corresponds to the next inclined sawtooth surface of the limiting tooth 7.

[0053] In this way, by repeatedly pressing the locked part 3, the rotating sliding part 2 can be driven to move back and forth within the housing 1, realizing the intermittent rotation of the rotating sliding part 2 and switching between the unlocked and locked states.

[0054] The locking element 11 is a spherical or ellipsoidal structure, or it is a cylindrical structure with hemispherical ends. The inner edge of the mounting hole 10 is an arc-shaped opening with a diameter smaller than that of the locking element 11, so that only a part of the inner end of the locking element 11 can enter the slot 9.

[0055] As a preferred option, the front end of the snap-fit ​​part 3-2 has a hemispherical structure, and the snap-fit ​​part 3-2 and the main body 3-1 have an arc transition.

[0056] As a preferred option, port 13 is flared to facilitate the insertion and guidance of the locking element 11.

[0057] As a preferred option, the housing 1 has a split structure, specifically including a main body 1-1 and an end cap 1-2. A port 13 is provided on the end cap 1-2, and the end cap 1-2 is detachably connected to the end of the main body 1-1. A recessed groove 12 is formed between the inner end face of the end cap 1-2 and the end of the main body 1-1. The connection between the end cap 1-2 and the housing 1 can be a threaded connection, a snap-fit ​​connection, or a plug-in connection.

[0058] As a preferred option, the elastic element 4 is a spring.

[0059] like Figures 9 to 12 The diagram shows the principle of the rotating sliding component 2 reciprocating and rotating along the axis within the housing during a single press. Figure 9 As shown, the rotating sliding member 2 moves along the axis, and the second rotating driving tooth 6 approaches the first rotating driving tooth 5; as Figure 10 As shown, the second rotary drive tooth 6 contacts the first rotary drive tooth 5, and under the action of the inclined tooth surface, the rotary sliding member 2 rotates around the axis by half an angle; as Figure 11 As shown, the second rotary drive tooth 6 is fully engaged with the first rotary drive tooth 5; as Figure 12 As shown, the rotating sliding member 2 moves along the axis, the second rotating driving tooth 6 moves away from the first rotating driving tooth 5, the guide tooth 8 contacts the inclined surface of the limiting tooth 7, and under the action of the limiting tooth 7, the rotating sliding member 2 rotates around the axis by the remaining half angle.

[0060] Example 2

[0061] like Figure 6 As shown, the structure of this embodiment is basically the same as that of the first embodiment. The difference is that in this embodiment, the first rotary drive tooth 5 is directly set on the inner wall of the housing 1, and the end of the elastic member 4 is directly in contact with the inner end face of the housing 1. This can reduce one component and eliminate the need to set the slide groove 16 to restrict the rotation of the drive member 17.

[0062] Example 3

[0063] likeFigure 7 As shown, this embodiment is a form of use of a semi-automatic press-lock structure. In the structure of Embodiment 1 or Embodiment 2, a through hole 18 is opened along the axis. The through hole 18 passes through the housing 1, the rotating sliding member 2, the locked member 3, etc. The rope 19 passes through the end away from the port 13 of the housing 1 and is connected to the locked member 3. At the same time, a fastening hole 14 is opened on the locked member 3, and a fastening rope is connected to the fastening hole 14. Pulling the rope 19 can lock or unlock the locked member 3. This structure can be applied to the locking of schoolbag straps or shoelaces, etc.

[0064] Example 4

[0065] like Figure 8 As shown, this embodiment is another form of use of the semi-automatic push-to-lock structure. In the structure of Embodiment 1 or Embodiment 2, the housing 1 is fixedly installed, such as fixed to a door frame, wall or door, and the locking part 3 is fixed to the corresponding structure through a connecting post to form a door catch structure or a push-pull door locking structure, etc. When locking, the door is pushed to move, so that the housing 1 and the locking part 3 are close to each other, and the locking part 3 is inserted into the port 13 of the housing 1. Locking is achieved by pressing and rotating the sliding part. When unlocking is required, the door is pushed to bring the housing 1 and the locking part 3 close to each other again, and unlocking is achieved by pressing and rotating the sliding part again.

[0066] This invention's semi-automatic push-to-lock structure allows for locking and unlocking of the locked component 3 through a single-direction pressing force, simplifying operation. Furthermore, the mechanical structure of this semi-automatic push-to-lock structure is relatively simple, eliminating the need for a separate unlocking mechanism. This semi-automatic push-to-lock structure can be applied to various occasions such as locking shoelaces, backpack straps, sliding doors, and door closers, offering a wide range of applications. The size and shape of this invention can be adjusted according to needs and application scenarios.

[0067] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
