Description

Technical Field

[0001] The present invention relates to a locking mechanism, specifically a semi-automatic pressing locking structure. Background Art

[0002] Locking structures are required in various fields of life, such as the locking of shoelaces, the locking of schoolbag laces, the locking of sliding doors, and the locking of door stoppers. Through the locking structure, two components are brought close to each other and temporarily locked, and can be unlocked when needed so that the two components can be separated from each other. However, the existing locking structures generally require two parts, a locking structure and an unlocking structure, which have the problems of relatively complex structures and operations. Summary of the Invention

[0003] The purpose of the present invention is to provide a semi-automatic pressing locking structure to solve the problems of relatively complex structures and operations existing in the existing locking structures.

[0004] The present invention is implemented as follows: A semi-automatic pressing locking structure includes: A housing, the inner cavity of the housing is cylindrical, and one end of the housing is provided with a port for a locking member to pass through; A pressing and displacement mechanism, including a rotating and sliding member and an elastic member disposed in the housing. A first rotating drive tooth is provided at one end of the housing away from the port. The elastic member is located at one end of the rotating and sliding member away from the port. Limiting teeth are provided on the inner wall of the housing. Guide teeth are provided on the outer wall of the rotating and sliding member. A second rotating drive tooth is provided at the end of the rotating and sliding member; A locking structure, including a slot disposed on the rotating and sliding member. The slot is coaxial with the rotating and sliding member. Mounting holes are circumferentially distributed on the side wall of the slot. Locking members are respectively installed in the mounting holes. A yielding groove is provided on the inner wall of the housing; A locked member, including a body and a clamping portion at the end of the body. The diameter of the clamping portion is greater than the diameter of the body. A stepped structure is formed at the connection between the clamping portion and the body. The clamping portion is used for being inserted into the slot and being clamped by the locking member.

[0005] Among them, the first rotating drive tooth has various implementation manners.

[0006] In the first manner, the first rotating drive teeth are circumferentially distributed on the inner wall of the housing.

[0007] In the second manner, a driving member is provided at one end of the housing away from the port. The first rotating drive teeth are circumferentially distributed at the end of the driving member. An axial chute is provided on the inner wall of the housing. A slider is provided on the outer wall of the driving member. The slider is slidably connected to the chute. A baffle for contacting the elastic member is provided on the driving member.

[0008] As a further improvement of the semi-automatic pressing type locking structure of the present invention, there are several limiting teeth which are evenly distributed circumferentially on the inner wall of the housing. The number of guiding teeth is the same as that of the limiting teeth and they are evenly distributed circumferentially on the outer wall of the rotating and sliding member. One end of the limiting tooth is two consecutive inclined sawtooth surfaces, the end of the guiding tooth is an inclined surface, and a sliding channel is formed between two adjacent limiting teeth.

[0009] As a further improvement of the semi-automatic pressing type locking structure of the present invention, the locking member is a spherical ball or an ellipsoidal ball, and the inner end edge of the mounting hole is an arc-shaped closing opening.

[0010] As a further improvement of the semi-automatic pressing type locking structure of the present invention, the front end of the clamping portion is a semi-spherical structure.

[0011] As a further improvement of the semi-automatic pressing type locking structure of the present invention, through holes are provided in the end face of the housing, the rotating and sliding member, and the center of the locked member, and a lacing hole is provided on the body of the locked member.

[0012] As a further improvement of the semi-automatic pressing type locking structure of the present invention, the housing includes a main body and an end cover. The port is provided on the end cover, and the end cover is detachably connected to the end of the main body. A yielding groove is formed between the inner end face of the end cover and the end of the main body.

[0013] As a further improvement of the semi-automatic pressing type locking structure of the present invention, the port is in the shape of a flared opening.

[0014] As a further improvement of the semi-automatic pressing type locking structure of the present invention, the elastic member is a spring.

[0015] The locking and unlocking principles of the present invention are as follows: In the initial state, under the action of the elastic member, the rotating and sliding member approaches the port. At this time, the position of the locking member coincides with the position of the retraction groove, and the locking member can retract into the retraction groove. The locked member can be smoothly inserted into the slot of the rotating and sliding member. Under the action of an external force, the locked member continues to move axially. The locked member pushes the rotating and sliding member away from the port through the limiting teeth and compresses the elastic member. The guiding teeth on the rotating and sliding member disengage from the limiting teeth, and the rotating and sliding member can rotate around the axis of the housing. The inclined surfaces of the first rotating drive teeth at the end of the housing and the second rotating drive teeth at the end of the rotating and sliding member come into contact with each other to drive the rotation of the rotating and sliding member. During the process of the rotating and sliding member moving away from the port, the locking member disengages from the retraction groove. Under the extrusion of the inner wall of the housing, a part of the locking member is located in the slot, and the part of the locking member located in the slot clamps the clamping portion of the locked member. After removing the external force, under the reset action of the elastic member, the rotating and sliding member is driven to approach the port. Since the rotating and sliding member has rotated by a certain angle, at this time, the limiting teeth block the guiding teeth on the outer wall of the rotating and sliding member and drive the rotating and sliding member to rotate by a certain angle again. Due to the blocking of the limiting teeth, the rotating and sliding member cannot continue to approach the port, and the locking member cannot enter the retraction groove. The locking member maintains the clamping of the locked member, thereby realizing the locking of the locked member.

[0016] When unlocking is required, an external force is applied again to make the locked member push the rotating and sliding member away from the port and compress the elastic member. The guiding teeth on the rotating and sliding member disengage from the limiting teeth, and the inclined surfaces of the first rotating drive teeth and the second rotating drive teeth come into contact with each other to drive the rotation of the rotating and sliding member. After removing the external force, under the reset action of the elastic member, the rotating and sliding member is driven to approach the port. Since the rotating and sliding member has rotated by a certain angle, the limiting teeth guide the guiding teeth on the outer wall of the rotating and sliding member and drive the rotating and sliding member to rotate by a certain angle again. The guiding teeth enable the rotating and sliding member to approach the port through the limiting teeth, so that the locking member can enter the retraction groove, thereby realizing the unlocking of the locked member. After unlocking, the locked member can be pulled out of the slot.

[0017] The semi-automatic pressing type locking structure of the present invention drives the intermittent rotation of the rotating and sliding member through the contact of the first rotating drive teeth and the second rotating drive teeth and the cooperation of the guiding teeth and the limiting teeth, and at the same time enables the rotating and sliding member to switch between two different extreme positions, thereby realizing the switching between the locked state and the unlocked state. The semi-automatic pressing type locking structure of the present invention can realize the locking and unlocking of the locked member with a pressing force in one direction, which simplifies the operation. At the same time, the mechanical structure of the semi-automatic pressing type locking structure of the present invention is relatively simple and does not require a separate unlocking structure.

[0018] The semi-automatic pressing type locking structure of the present invention can be applied to various occasions such as the locking of shoelaces, the locking of schoolbag ties, the locking of sliding doors, and the locking of door stoppers, etc., and has a wide range of applications.

[0032] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0033] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0034] Embodiment 1 As Figures 1 to 5 shown, the semi-automatic pressing and locking structure in this embodiment includes a housing 1, a pressing and position-changing mechanism, a locking structure, and a locked part 3, etc.

[0035] Among them, the inner cavity of the housing 1 is cylindrical, and the outer shape of the housing 1 can be cylindrical or other shapes. A port 13 is provided at one end of the housing 1, and this port 13 is used for the locked part 3 to enter the interior of the housing 1 and be locked by the locking structure.

[0036] The locked part 3 includes a body 3-1 and a clamping part 3-2 at the end of the body 3-1. The diameter of the clamping part 3-2 is larger than that of the body 3-1, and a stepped structure is formed at the connection between the clamping part 3-2 and the body 3-1. One end of the clamping part 3-2 of the locked part 3 enters the housing 1 from the port 13 of the housing 1, and the clamping part 3-2 is locked or unlocked by the locking structure.

[0037] The locking and unlocking of the locked part 3 are realized by the cooperation of the pressing and position-changing mechanism and the locking structure.

[0038] The pressing and position-changing mechanism includes a rotating and sliding part 2, an elastic part 4, etc. The rotating and sliding part 2 is located in the inner cavity of the housing 1, and the rotating and sliding part 2 can slide along the axial direction of the inner cavity of the housing 1 and rotate around the axis of the inner cavity of the housing 1.

[0039] The locking structure includes a slot 9 provided on the rotary sliding member 2. The slot 9 is coaxial with the rotary sliding member 2 and is located at one end of the rotary sliding member 2 close to the port 13 of the housing 1. During operation, the locked member 3 enters the housing 1 from the port 13, and the clamping portion 3-2 of the locked member 3 is inserted into the slot 9. The diameter of the clamping portion 3-2 of the locked member 3 is slightly smaller than the diameter of the inner wall of the slot 9, so that it can just be inserted into the slot 9. A number of mounting holes 10 are evenly distributed circumferentially on the side wall of the slot 9. A locking member 11 is respectively installed in each mounting hole 10. The length of the mounting hole 10 is less than the length or diameter of the locking member 11, so that a part of the locking member 11 always protrudes from the inner end or the outer end of the mounting hole 10. At the same time, a relief groove 12 is provided on the inner wall of the housing 1.

[0040] When the rotary sliding member 2 moves so that the outer end of the locking member 11 can enter the relief groove 12, when the clamping portion 3-2 of the locked member 3 is inserted into the slot 9 and passes through the locking member 11, it will squeeze the locking member 11 to move it outward into the relief groove 12. The locking member 11 cannot block the insertion or detachment of the locked member 3 from the slot 9. At this time, it is in the unlocked state. When the rotary sliding member 2 moves so that the locking member 11 disengages from the relief groove 12, under the extrusion of the inner wall of the housing 1, a part of the inner end of the locking member 11 enters the slot 9. 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 locked member 3. At this time, the locking member 11 is clamped outside the clamping portion 3-2 and can prevent the locked member 3 from being disengaged from the slot 9. At this time, it is in the locked state.

[0041] The elastic member 4 is located at one end of the rotary sliding member 2 away from the port 13 of the housing 1. Under the action of the elastic member 4, the rotary sliding member 2 has a tendency to move towards the port 13 of the housing 1. The above-mentioned unlocked state and locked state are realized by two limit positions of the rotary sliding member 2. The two limit positions are restricted by the cooperation of the limit teeth 7 on the inner wall of the housing 1 and the guiding teeth 8 on the outer wall of the rotary sliding member 2.

[0042] There are a plurality of limit teeth 7 and they are evenly distributed circumferentially around the axis of the inner cavity of the housing 1. The limit teeth 7 specifically include two consecutive inclined sawtooth surfaces, and the two consecutive inclined sawtooth surfaces are located at one end away from the port 13 of the housing 1. The number of guiding teeth 8 is the same as the number of limit teeth 7 and they are evenly distributed circumferentially on the outer wall of the rotary sliding member 2. The end of the guiding tooth 8 is an inclined surface, and the inclined surface is located at one end close to the port 13 of the housing 1. The inclined sawtooth surface of the limit tooth 7 and the inclined surface of the guiding tooth 8 have the same inclination direction. A sliding channel 15 that can accommodate the guiding tooth 8 to pass through is formed between two adjacent limit teeth 7.

[0043] When the inclined surface of the guiding tooth 8 contacts the first inclined serrated surface of the limiting tooth 7, under the action of the elastic member 4, the guiding tooth 8 enters the groove formed by two consecutive inclined serrated surfaces, and at the same time, the rotating and sliding member 2 rotates by a certain angle. At this time, the limiting tooth 7 restricts the guiding tooth 8 and the rotating and sliding member 2 from approaching the port 13 of the housing 1. This is the first limit position of the rotating and sliding member 2, corresponding to the locked state.

[0044] When the inclined surface of the guiding tooth 8 contacts the second inclined serrated surface of the limiting tooth 7, under the action of the elastic member 4, the guiding tooth 8 moves along the inclined serrated surface until it enters the sliding channel 15. At the same time, the rotating and sliding member 2 rotates by a certain angle. At this time, the limiting tooth 7 cannot restrict the guiding tooth 8 and the rotating and sliding member 2 from approaching the port 13 of the housing 1. The rotating and sliding member 2 approaches the port 13 of the housing 1 until the end of the rotating and sliding member 2 contacts the inner end surface of the housing 1. This is the second limit position of the rotating and sliding member 2, corresponding to the unlocked state.

[0045] The guiding tooth 8 of the rotating and sliding member contacts different inclined serrated surfaces of the limiting member, finally forming the above two different states. The contact between the guiding tooth 8 of the rotating and sliding member and different inclined serrated surfaces of the limiting member is realized by the rotation of the rotating and sliding member. In order to realize the rotation of the rotating and sliding member 2, a driving member 17 is arranged at one end of the housing 1 far from the port 13. The first rotating driving teeth 5 are circumferentially distributed at the end of the driving member 17. An axial sliding groove 16 is formed on the inner wall of the housing 1. A sliding block is arranged on the outer wall of the driving member 17, and the sliding block is slidably connected with the sliding groove 16. A baffle for contacting the elastic member 4 is arranged on the driving member 17. A ring of second rotating driving teeth 6 is arranged at one end of the rotating and sliding member 2 far from the 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.

[0046] When the guiding tooth 8 is located in the groove formed by two consecutive inclined serrated surfaces or the guiding tooth 8 is located in the sliding channel 15, the first rotating driving teeth 5 and the second rotating driving teeth 6 are staggered by a very small distance from each other, so that the first rotating driving teeth 5 and the second rotating driving teeth 6 are generally corresponding to each other. However, when the second rotating driving teeth 6 approach and contact the first rotating driving teeth 5, the inclined tooth surfaces of the first rotating driving teeth 5 and the second rotating driving teeth 6 contact each other and drive the rotating and sliding member 2 to rotate by a certain angle under the action of pressure. After rotating by a certain angle, the rotating and sliding member 2 corresponds to the next inclined serrated surface of the limiting tooth 7.

[0047] In this way, by repeatedly pressing the locked part 3, the rotating and sliding member 2 can be driven to reciprocate in the housing 1, realizing the intermittent rotation of the rotating and sliding member 2 and the switching between the unlocked and locked states.

[0048] Among them, the locking member 11 is in the structure of a spherical ball or an elliptical ball, or the locking member 11 is in the structure of a cylinder with hemispherical ends at both ends. The inner end edge of the mounting hole 10 is in an arc-shaped closed end, and the diameter of the arc-shaped closed end is smaller than the diameter of the locking member 11, so that only a part of the inner end of the locking member 11 can enter the slot 9.

[0049] As a preferable option, the front end of the clamping portion 3-2 is in the structure of a semi-spherical ball, and there is an arc transition between the clamping portion 3-2 and the main body 3-1.

[0050] As a preferable option, the port 13 is in the shape of a flared opening, which is convenient for guiding the insertion of the locking member 11.

[0051] As a preferable option, the housing 1 is in a split structure. Specifically, the housing 1 includes a main body 1-1 and an end cover 1-2. The port 13 is opened on the end cover 1-2. There is a detachable connection between the end cover 1-2 and the end of the main body 1-1, and a yielding groove 12 is formed between the inner end surface of the end cover 1-2 and the end of the main body 1-1. Among them, the connection between the end cover 1-2 and the housing 1 can be a threaded connection, a clamping connection, a plug-in connection or other connection methods.

[0052] As a preferable option, the elastic member 4 is a spring.

[0053] As shown in Figures 9 to 12 the figure, it is a schematic principle diagram of the reciprocating movement and rotation of the rotary sliding member 2 along the axis in the housing during a single pressing process. As shown in Figure 9 the figure, the rotary sliding member 2 moves along the axis, and the second rotary driving tooth 6 approaches the first rotary driving tooth 5; as shown in Figure 10 the figure, the second rotary driving tooth 6 contacts the first rotary driving tooth 5, and under the action of the inclined tooth surface, the rotary sliding member 2 rotates by a half angle around the axis; as shown in Figure 11 the figure, the second rotary driving tooth 6 is in full meshing contact with the first rotary driving tooth 5; as shown in Figure 12 the figure, the rotary sliding member 2 moves along the axis, the second rotary driving tooth 6 moves away from the first rotary driving tooth 5, the guiding tooth 8 contacts the inclined surface of the limiting tooth 7, and under the action of the limiting tooth 7, the rotary sliding member 2 rotates by the remaining half angle around the axis.

[0054] Embodiment 2 As shown in Figure 6 the figure, the structure of this embodiment is basically the same as that of Embodiment 1, the difference being that in this embodiment, the first rotary driving tooth 5 is directly arranged on the inner wall of the housing 1, and the end of the elastic member 4 directly contacts the inner end surface of the housing 1, so that one component can be reduced and there is no need to provide a sliding groove 16 to limit the rotation of the driving member 17.

[0055] Embodiment 3 As shown in Figure 7As shown, this embodiment is a usage form of the semi-automatic pressing type locking structure. In the structure of Embodiment 1 or Embodiment 2, a through hole 18 is opened along the axis, and the through hole 18 penetrates through the housing 1, the rotating and sliding member 2, the locked member 3, etc. The rope 19 penetrates from one end far away from the port 13 of the housing 1 and is connected to the locked member 3. At the same time, a lacing hole 14 is opened on the locked member 3, and a lacing rope is connected to the lacing hole 14. Pulling the rope 19 can lock or unlock the locked member 3. This structure can be applied to the locking of schoolbag laces or shoelaces, etc.

[0056] Embodiment 4 As Figure 8 As shown, this embodiment is another usage form of the semi-automatic pressing type locking structure. In the structure of Embodiment 1 or Embodiment 2, the housing 1 is fixedly arranged, such as fixed on a door frame, a wall or a door, and the locked member 3 is fixed on the corresponding structure through a connecting column to form a door stopper structure or a sliding door locking structure, etc. When locking, push the door to move, so that the housing 1 and the locked member 3 approach each other, and the locked member 3 is inserted into the port 13 of the housing 1, and locking is achieved by pressing the rotating and sliding member. When unlocking is required, push the door to make the housing 1 and the locked member 3 approach each other again, and unlocking is achieved by pressing the rotating and sliding member again.

[0057] The semi-automatic pressing type locking structure of the present invention can lock and unlock the locked member 3 with a pressing force in one direction, which simplifies the operation. At the same time, the mechanical structure of the semi-automatic pressing type locking structure of the present invention is relatively simple and does not require a separate unlocking structure. The semi-automatic pressing type locking structure of the present invention can be applied to various occasions such as the locking of shoelaces, the locking of schoolbag laces, the locking of sliding doors, and the locking of door stoppers, etc., and has a wide application range. The present invention can adjust its size and shape according to needs and application scenarios.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
