Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of lock catch, specifically relates to a rotating mechanism and lock catch for lock catch. BACKGROUND

[0002] The lock catch is used in the scene of completing the opening and closing action of bags, clothes and the like, such as being applied to clothes, and is mostly applied to the opening and closing use on the door collar and pocket, and has variable and beautiful shapes. However, when the existing lock catch is buckled on the clothes, the opening and closing is manually operated, and the rotation head needs to be manually operated by hand when being locked, which is not convenient to operate, and is prone to misalignment, i.e. unable to rotate to the target angle, such as 90° relative to the initial state. Meanwhile, the following needs to be further improved, such as the existing lock catch needing to be manually operated to rotate, and each opening and closing operation needs to be manually rotated once, which is inconvenient to operate. In addition, some rotation heads are small, and the hand is not easy to hold, such as in winter when wearing gloves and the like in the scene of interfering with rotation, since the rotation is small, it is difficult to hold and rotate the rotation head. Meanwhile, manual rotation of the lock head is prone to misalignment caused by artificial operation, and the lock head is not properly positioned, and after rotation, the lock head is not clamped at the alignment point, and is prone to rebound and scratch. Therefore, it is necessary to develop a rotating mechanism and lock catch for lock catch. SUMMARY

[0003] The utility model discloses a rotating mechanism and lock catch for lock catch to solve the above technical problems, set up the trigger mechanism, and release the rotation head by the resistance of the trigger mechanism, realize the rotation of the rotation head, reach the effect that the rotation head rotates from the first state to the second state under the action of the torsion after the resistance, this kind of mode can effectively prevent the problem of misalignment, and the rotation head rotates to the target second state after the release of the limit by the preset torsion, and the operation is simple and reliable. Meanwhile, the initial state of the rotation head in the trigger mechanism is the first state of being limited to rotate, until the trigger mechanism is resisted and the limitation on the rotation head is removed, and the rotation head rotates to the second state, so that the user only needs to twist the rotation head once to reset to the first state, and the realization of rotating to the second state only needs to trigger by the resistance mode, which is convenient to operate and avoids the need for multiple manual rotation operations.

[0004] To achieve the above utility model purposes, the technical scheme adopted by the utility model is as follows:

[0005] A rotating mechanism for a lock buckle, comprising a rotating head connected to a trigger mechanism that rotates the rotating head by abutting to release torsion. The trigger mechanism is arranged and the rotation of the rotating head is achieved by abutting the trigger mechanism to release the rotating head, achieving the effect of rotating the rotating head from the first state to the second state under the action of torsion after abutting. This method can effectively prevent the problem of misrotation. The rotating head is rotated to the target second state after releasing the limit by the preset torsion. The operation is simple and reliable. At the same time, the initial state of the rotating head in the trigger mechanism is the first state of being limited to rotate, until the trigger mechanism is abutted to release the limitation of the rotating head, and the rotating head is rotated to the second state. The user only needs to twist the rotating head once to reset it to the first state, and the rotation to the second state is only triggered by abutting, which is convenient to operate and avoids the need for multiple manual operations to rotate.

[0006] When it is necessary to match with the lock buckle surface piece, the rotating head is rotated to the first state alone, then the lock buckle surface piece is inserted, the trigger mechanism is abutted, the rotating head is rotated to the second state, and the locking action is completed, avoiding the cumbersome action of rotating the rotating piece to match the angle of the lock buckle surface piece, inserting the lock buckle surface piece, and manually rotating the rotating head in the prior art. At the same time, it avoids the problem that the user cannot hold the rotating head or the rotating head cannot rotate to the right position due to operation interference such as wearing gloves when the space is small after matching the lock buckle surface piece. The limitation of the rotating head is released by abutting, and it is automatically rotated to the second state under the action of torsion, which is convenient to operate and has high reliability.

[0007] And the stability of the position rotated to the target second state under the action of torsion is strong, which can effectively cooperate with the lock buckle surface piece to complete the locking action, avoid the problem of not locking due to unstable rotation of the rotating head to the target position such as the vertical point, and the rotating head slipping out of the hole piece.

[0008] Preferably, the trigger mechanism comprises a seat body limiting the axial direction stroke of the rotating head, a locking mechanism connected with the seat body and transmitting torque to rotate the rotating head after being moved by contact, and one end of the rotating head is connected with the locking mechanism. One side of the rotating head is arranged towards the seat body to cooperate with the locking mechanism to release the locking process of the rotating head. The seat body and the locking mechanism are arranged, and when the rotating head rotates to a first state limited by the locking mechanism, the rotating head is then moved in the same axial direction of the seat body to limit the stroke of the rotating head after the locking mechanism is moved by contact, and the rotating head is out of the locking end of the locking mechanism. The rotating path of the rotating head is in a non-blocked state, and the rotating head is automatically rotated to a second state under the action of torque. This kind of mode can effectively prevent the problem of rotation misalignment. The rotating head is rotated to the target second state after releasing the limit by the preset torque, and the operation is simple and reliable. At the same time, the initial state of the rotating head in the locking mechanism is the first state of being limited to rotate, and the rotating head is rotated to the second state only after the locking mechanism is contacted to release the limitation of the rotating head. The user only needs to twist the rotating head once to reset it to the first state, and the rotation to the second state is only triggered by the contact mode, which is convenient to operate and avoids the need for multiple manual operations.

[0009] When matching with the lock surface part is needed, the rotating head is rotated to the first state alone, then the lock surface part is inserted, the locking mechanism is contacted, and the limitation of the rotating head is released under the action of the seat body to limit the stroke, so that the rotating head is rotated to the second state, thereby completing the locking action. This avoids the cumbersome action of rotating the rotating part to match the angle of the lock surface part in advance, inserting the lock surface part, and manually rotating the rotating head in the prior art. At the same time, it avoids the problem that the user cannot hold the rotating head or the rotating head cannot rotate to the right position due to the operation interference such as wearing gloves when the operation space is small after matching the lock surface part. The limitation of the rotating head is released by the contact mode, and the rotating head is automatically rotated to the second state under the action of torque, which is convenient and reliable to operate.

[0010] The stability of the position of the rotating head rotated to the target second state under the action of torque is strong, which can effectively cooperate with the lock surface part to complete the locking action, avoid the problem that the rotating position of the rotating head is unstable due to manual operation and the rotating head does not rotate to the target position such as the vertical point, thereby causing the problem that the rotating head is not locked and slides out of the hole part.

[0011] Preferably, the locking mechanism includes a lock cylinder that restricts rotation of the rotating head after being moved against the seat body to match the rotating head travel limit to release the rotation restriction, an elastic part connected with the lock cylinder and corresponding to transmit the torsion to the rotating head, the elastic part is connected with the rotating head, and the lock cylinder is movably connected with the seat body. The elastic part is specifically a spring, a clockwork or other component with elasticity and capable of transmitting torsion. In the technical solution, the spring is used as the elastic part, the lock cylinder and the elastic part are arranged, the elastic part is arranged in the lock cylinder and connected with the lock cylinder at one end, the other end of the elastic part is connected with the connecting part of the rotating head inserted into the lock cylinder, the rotating head, the spring and the lock cylinder are sequentially sleeved, the rotating head extends to the outside through the spring and the lock cylinder, the torsion of the spring can be effectively transmitted to the rotating head, the structure is stable, in the first state in which the lock cylinder restricts the rotation of the rotating head, the lock cylinder is moved along the axial direction of the seat body by being moved against the lock cylinder, the rotating head is moved along the axial direction of the lock cylinder due to the fact that one end of the rotating head is connected with the spring, at this time, the rotating head is separated from the lock cylinder due to the travel limit of the seat body to the rotating head, so that the rotating head is released from the lock end of the lock cylinder, and the rotation of the rotating head is released, the rotating head is rotated to the second state under the action of the torsion of the spring, at this time, the movement of the lock cylinder compresses the spring, the operation is simple and reliable;

[0012] When the lock catch surface part needs to be matched, the rotating head is rotated to the first state, then the lock catch surface part is inserted, the lock cylinder is moved against the lock catch surface part, the rotation of the rotating head is released under the action of the travel limit of the seat body, and the rotating head is rotated to the second state, so that the locking action is completed, the cumbersome action of rotating the rotating part to the angle matched with the lock catch surface part, inserting the lock catch surface part and manually rotating the rotating head in the prior art is avoided, and the problem that the user cannot hold the rotating head or the rotating head cannot be rotated to the position due to the operation interference such as wearing gloves when the operation space is small after the lock catch surface part is matched is avoided, the rotating head is released by the abutting mode, and the rotating head is automatically rotated to the second state under the action of the torsion, the operation is convenient and the reliability is high,

[0013] the rotating head is rotated to the target second state position under the action of the torsion, the stability is high, the lock catch surface part can be effectively matched to complete the locking action, the problem that the rotating head is not rotated to the target position such as the vertical point and cannot be locked and the rotating head is out of the hole part due to manual operation is avoided.

[0014] Preferably, the lock cylinder is provided with a first clamping groove and a first clamping point corresponding to the outside of the first clamping groove; the rotating head comprises a rotating head body, a connecting portion connected with the elastic portion, a first limiting portion provided on the rotating head body and embedded in the first clamping groove to be locked, and a first fitting surface for abutting the seat after the lock cylinder is moved to abut the seat and make the first limiting portion disengage from the first clamping groove. The first clamping groove and the first limiting portion are correspondingly arranged in groups, and one group or two groups or multiple groups are provided. In the axial projection of the lock cylinder, the first clamping groove is arranged at a position where the rotating head body and the first segment projection surface coincide in the first state; when the elastic portion is embedded in the first limiting portion and the first clamping groove, a torsion force exists to make the rotating head rotate from the first state to the second state;

[0015] The first limiting portion is arranged between the connecting portion and the first fitting surface, and the rotating head body is connected with the connecting portion. The upper end of the seat is arranged towards the rotating head, specifically, the second fitting surface is arranged on the upper end of the seat and opposite to the first fitting surface;

[0016] The spring is connected with the connecting portion. The spring not only has the function of transmitting torsion force, but also has the function of preventing the reverse of the abutting surface of the rotating head and the seat from being completely disengaged to the outside, so that the overall stability is stronger. The connecting portion, the spring and the lock cylinder are connected in layers outward. The first limiting portion penetrates the lock cylinder, the seat and the rotating head body extending to the outside. The first clamping groove is arranged, and the rotating head is provided with the first limiting portion. By rotating the rotating head body and embedding the first limiting portion in the first clamping groove, the first state is formed. When the rotating head needs to rotate to the second state, the lock cylinder is moved along the axial direction of the seat by abutting the lock cylinder. Due to the connection of one end of the connecting portion with the spring, the rotating head has the tendency to move axially with the lock cylinder. At this time, due to the travel limiting of the seat to the rotating head, the rotating head is separated from the lock cylinder, so that the first clamping groove and the first limiting portion are in a separated state, thereby disengaging from the locking end of the lock cylinder, thereby releasing the restriction of the rotating head, and rotating to the second state under the action of the torsion force of the spring. The operation is simple and reliable. At the same time, the initial state of the rotating head in the lock cylinder is the first state of being restricted to rotate, until the lock cylinder is abutted to release the restriction of the rotating head, and the rotating head rotates to the second state. The user only needs to twist the rotating head once to reset it to the first state. The realization of rotating to the second state only needs to be triggered by abutting, which is convenient to operate and avoids the need for multiple manual operations. The rotation of the rotating head is limited by embedding, which is reliable and easy to implement. The rotating head can complete the first state action before being inserted into the lock catch surface, and after being inserted into the lock catch surface, the first clamping groove and the first limiting portion are separated by abutting, and the rotating head automatically rotates under the action of torsion force transmission to complete the locking action, which is convenient to operate.

[0017] Preferably, the seat body, the lock core, the elastic part and the rotating head are sequentially sleeved from outside to inside. The rotating head penetrates the lock core and the seat body at the shaft center and extends to the outside. The spring is arranged inside the lock core to transmit the torsion to the connecting part and limit the rotating head from being completely separated from the lock core. The lock core and the seat body are movably connected, so that the lock core can be moved in the seat body to make the rotating head have a moving trend, but the seat body arranged outside the lock core is in contact to separate the lock core and the rotating head. The multiple components cooperate to complete the limiting action and the releasing action, the implementation process is simple and reliable, the rotating head is separated by limiting the stroke to release the limitation of the rotating head, the torsion is transmitted by the spring, the response speed is fast, and the operation is convenient.

[0018] Preferably, the seat body is provided with a first groove body, the lock core is provided with a contact block body movably connected with the first groove body, and the contact block body penetrates the first groove body. Preferably, the contact block body penetrates the first groove body and extends to the outside, so that the contact block body is convenient to be contacted and the lock core is driven more conveniently. The first groove body and the contact block body are correspondingly arranged in groups, and one group or more groups are arranged. The lock core is connected with the contact block body, the contact block body penetrates the first groove body, the initial state of the rotating head is the first state, the contact block body is contacted and moved in the state of being limited by the first groove body, so as to drive the lock core to move. The lock core is connected with the spring, the spring applies an axial moving trend force to the connecting part, so that the rotating head is blocked by the seat body, the rotating head is separated from the lock core, and the rotating head is rotated to the second state under the torsion of the spring.

[0019] Preferably, the seat body is provided with a second clamping point corresponding to the end of the rotating path of the first limiting part. The projection of the first clamping groove and the second clamping point in the axial direction of the lock core does not overlap. The axial projection of the trigger mechanism is taken with the shaft center of the trigger mechanism as the center, and there is a certain angle X between a single first clamping groove and a second clamping point. In the initial state, the direction of the torsion release of the spring is from the first clamping groove to the second clamping point. Preferably, the second clamping point is arranged at an angle X of 90° between the first clamping groove and the shaft center. The first clamping groove and the second clamping point are correspondingly arranged in groups, and one group or two groups or more groups are arranged. The second clamping point limits the rotating angle of the first limiting part, so that the rotating head is stably rotated to the target second state, and the problem that the rotating angle is too large to effectively cooperate with the lock catch surface to achieve the locking action can be effectively avoided. The preset torsion of the spring has a certain fault tolerance, the torsion setting margin is larger, the production difficulty is reduced, and the use stability of the overall structure is improved.

[0020] Preferably, the inner surface of the lock cylinder is provided with a second groove body connected to one end of the elastic part, and the side of the connecting part away from the first limiting part is provided with a connecting groove connected to the other end of the elastic part. The elastic part is specifically a spring. The second groove body is provided to connect one end of the spring, and the other end of the spring is connected to the connecting part. One end of the spring extends and enters the second groove body, and the second groove body is arranged to limit the spring in the circumferential direction when the rotating head is in the first state, i.e., when the spring is twisted, so that the spring has a certain torsional force to be released. When the rotating head needs to be rotated to the second state, the abutting block is abutted to drive the lock cylinder, the movement of the lock cylinder drives the spring to exert a force on the connecting part to move in the axial direction, so that the rotating head is blocked by the seat body, the rotating head is separated from the lock cylinder, and the rotating head is rotated to the second state under the torsional force of the spring.

[0021] Preferably, one end of the elastic part is provided with an extension part embedded in the second groove body, and the other end of the elastic part is provided with a bent part connected to the connecting groove. The extension part is embedded in the second groove body, so that one end of the spring is limited in the second groove body. The second groove body is arranged to limit the spring in the circumferential direction when the rotating part is in the first state, i.e., when the spring is twisted, so that the spring has a certain torsional force to be released. When the rotating head needs to be rotated to the second state, the abutting block is abutted to drive the lock cylinder, the movement of the lock cylinder drives the spring to exert a force on the connecting part to move in the axial direction, so that the rotating head is blocked by the seat body, the rotating head is separated from the lock cylinder, and the rotating head is rotated to the second state under the torsional force of the spring. The bent part is arranged to effectively connect the connecting part and the spring, and improve the connection stability of the two.

[0022] A lock catch includes the rotating mechanism of any one of the above, and further includes a lock catch surface member sleeved on the outer periphery of the trigger mechanism and abutting against the trigger mechanism to move to rotate the rotating head to complete the locking action. The initial angle of the rotating head is the first state. When the lock catch surface member abuts against the abutting block, the abutting block moves, the lock cylinder drives the first clamping groove to move, but the first abutting surface of the rotating head is blocked by the second abutting surface to limit the stroke, so that the first limiting part is separated from the first clamping groove to release the rotation restriction, and then the rotating head is rotated to a certain angle, i.e., the second state, under the torsional force of the spring. A second clamping point is arranged to limit the rotation angle of the rotating head. In this technical solution, the rotating head is rotated by 90° as the target angle, the rotated rotating head limits the lock catch surface member to avoid the lock catch surface member from being pulled out of the outside, so that the locking action is completed in the pressing mode.

[0023] The present application has the following beneficial technical effects:

[0024] This invention features a trigger mechanism. By abutting the trigger mechanism, the rotating head is released and rotated. Upon abutting, the rotating head rotates from a first state to a second state under torque. This method effectively prevents misalignment during rotation. A preset torque causes the rotating head to rotate to the target second state after the limit is released. The operation is simple and reliable. Furthermore, the rotating head is initially in the first state, restricted from rotation, until the trigger mechanism is abutted, releasing the restriction and allowing the rotating head to rotate to the second state. This means the user only needs to twist the rotating head once to reset it to the first state. The rotation to the second state is triggered by abutting, making operation convenient and avoiding multiple manual rotation operations.

[0025] When matching the locking facepiece is required, the reset rotating head is rotated separately to the first state, and then inserted into the locking facepiece. This abuts against the trigger mechanism, causing the rotating head to rotate to the second state, thus completing the locking action. This avoids the cumbersome steps of the prior art, which requires pre-rotating the rotating part to match the locking facepiece angle, inserting the locking facepiece, and manually rotating the rotating head. It also avoids problems such as users being unable to grasp the rotating head or the rotating head not rotating properly due to interference from factors like wearing gloves when the operating space is limited after engaging the locking facepiece. The rotating head automatically rotates to the second state under torque by abutting to release its limit, making operation convenient and highly reliable.

[0026] Furthermore, under the action of torque, it has strong stability when rotating to the target second state position, which can effectively cooperate with the locking surface to complete the locking action. This avoids the problem of the rotating head not locking properly and sliding out of the hole if the rotating head is not rotated to the target position such as the vertical point when manually operated.

DETAILED DESCRIPTION

[0049] In order to more clearly illustrate the technical solutions of the embodiments of the present application or the prior art, specific embodiments of the present application will be described below with reference to the drawings. Obviously, the drawings described below are only some embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative labor, and other embodiments can also be obtained.

[0050] The technical solutions of the present application will be described in detail below with specific embodiments.

[0051] Referring to Figures 1 to 20 A rotating mechanism for a lock catch, as shown in the figure, includes a rotating head 1, and the rotating head 1 is connected to a trigger mechanism 2 that releases the torsion to make the rotating head rotate. The trigger mechanism 2 is provided, and the rotating head 1 is released by abutting against the trigger mechanism 2 to realize the rotation of the rotating head 1, so as to achieve the effect that the rotating head 1 rotates from the first state to the second state under the action of the torsion after abutting. This kind of mode can effectively prevent the problem of rotation misalignment, and the rotating head 1 rotates to the target second state after being released from the limit by the preset torsion. The operation is simple and reliable. At the same time, the initial state of the rotating head in the trigger mechanism 2 is the first state of being limited to rotate, until the trigger mechanism 2 is abutted to release the limitation on the rotating head 1, and then the rotating head 1 rotates to the second state. The user only needs to twist the rotating head 1 once to reset it to the first state, and the realization of rotating to the second state only needs to be triggered by the abutting mode, which is convenient to operate and avoids the need for multiple manual operations to rotate;

[0052] When it is necessary to match with the lock surface piece, after rotating the reset rotary head 1 to the first state alone, then inserting the lock surface piece, the trigger mechanism 2 is abutted to make the rotary head 1 rotate to the second state, thereby completing the locking action, avoiding the cumbersome action of rotating the rotary piece to match the angle with the lock surface piece in advance, inserting the lock surface piece, and manually rotating the rotary head in the prior art, and avoiding the problem that the user cannot grab the rotary head 1 or the rotary head 1 cannot rotate to the position due to the operation interference such as wearing gloves when the operation space is small after matching the lock surface piece; the rotary head 1 is automatically rotated to the second state under the action of the torsion force by abutting to release the limiting of the rotary head 1, which is convenient to operate and has high reliability,

[0053] and the stability of rotating to the target second state position under the action of the torsion force is high, which can effectively cooperate with the lock surface piece to complete the locking action, avoiding the problem that the rotary head slips out of the hole piece due to the unstable rotation position of the manually operated rotary head without rotating to the target position such as the vertical point, thereby causing no locking.

[0054] The trigger mechanism 2 includes a seat body 21 limiting the axial direction stroke of the rotary head 1, a locking mechanism 22 connected with the seat body 21 and transmitting the torsion force to make the rotary head 1 rotate after being abutted and moved, and one end of the rotary head 1 is connected with the locking mechanism 22. One side of the rotary head 1 is arranged towards the seat body 21 to cooperate with the locking mechanism 22 to release the locking process of the rotary head 1, and the seat body 21 and the locking mechanism 22 are arranged, when the rotary head 1 rotates to the first state limited by the locking mechanism 22, then the locking mechanism 22 is moved by abutting, under the action of the seat body 21 moving in the same axial direction to limit the stroke of the rotary head 1, the rotary head 1 is out of the locking end of the locking mechanism 22, and the rotary path of the rotary head 1 is in the non-blocked state, and the rotary head 1 is automatically rotated to the second state under the action of the torsion force, which can effectively prevent the misalignment problem, the rotary head 1 is rotated to the target second state after releasing the limiting by the preset torsion force, which is simple and reliable in operation; at the same time, the initial state of the rotary head in the locking mechanism is the first state limited to rotate, until the locking mechanism 22 is abutted to release the limitation of the rotary head, and the rotary head 1 is rotated to the second state, so that the user only needs to twist the rotary head 1 once to reset to the first state, and the rotation to the second state is only triggered by abutting, which is convenient to operate and avoids the need for multiple manual operations;

[0055] When the reset rotary head 1 is rotated to the first state alone and then the lock surface part is inserted, the locking mechanism 22 is abutted and cooperates with the seat body to limit the stroke, thereby releasing the limit of the rotary head 1, rotating the rotary head 1 to the second state, and completing the locking action. This avoids the cumbersome action of rotating the rotary part to the angle matched with the lock surface part, inserting the lock surface part, and manually rotating the rotary head in the prior art. Meanwhile, when the lock surface part is matched, the user has less operating space, and the user cannot hold the rotary head or the rotary head 1 cannot be rotated to the position due to the operation interference such as wearing gloves, and the like. The rotary head 1 is automatically rotated to the second state under the action of the torsion force by the abutment release limit, is convenient to operate, and is strong in reliability,

[0056] and is strong in stability of the position rotated to the target second state under the action of the torsion force. The locking action can be effectively completed with the lock surface part, the rotary position is not stable when the rotary head is manually operated, the target position such as the vertical point is not rotated, thereby causing the problem of not being locked, and the rotary head 1 is out of the hole part.

[0057] The locking mechanism 22 includes a lock cylinder 221 that restricts the rotation of the rotating head 1 after being moved against the seat body 21 to restrict the stroke of the rotating head 1 to release the rotation restriction, an elastic part 222 connected with the lock cylinder 221 and corresponding to transmit the torsion to the rotating head 1, the elastic part 222 is connected with the rotating head 1, and the lock cylinder 221 is movably connected with the seat body 21. The elastic part 222 is specifically a spring, a clockwork or other components with elasticity and capable of transmitting torsion. In the technical solution, the spring is used as the elastic part, the lock cylinder 221 and the elastic part 222 are arranged, the elastic part 222 is arranged inside the lock cylinder 221 and connected with one end of the lock cylinder 221, the other end of the elastic part 222 is connected with the connecting part of the rotating head 1 inserted into the inside of the lock cylinder 221, the rotating head 1, the spring and the lock cylinder 221 are sequentially sleeved, and the rotating head 1 penetrates through the spring and the lock cylinder 221 and extends to the outside, so that the torsion of the spring can be effectively transmitted to the rotating head 1, and the structure has strong stability. In the first state in which the lock cylinder 221 restricts the rotation of the rotating head 1, the lock cylinder 221 is moved along the axial direction of the seat body 21 by being abutted, the rotating head 1 is inclined to move axially along with the lock cylinder 221 due to the fact that one end of the rotating head 1 is connected with the spring, at this time, the rotating head 1 is separated from the lock cylinder 221 due to the stroke limiting of the seat body 21 to the rotating head 1, so as to be released from the locking end of the lock cylinder 221, thereby releasing the rotation restriction of the rotating head 1, and the rotating head 1 is rotated to the second state under the action of the torsion of the spring. The operation is simple and reliable. Meanwhile, the rotating head 1 is in the first state of being restricted to rotate in the lock cylinder 221, until the lock cylinder 221 is abutted to release the rotation restriction of the rotating head 1, and the rotating head 1 is rotated to the second state, so that the user only needs to twist the rotating head 1 once to reset to the first state, and the rotation to the second state is triggered only by abutting, which is convenient to operate and avoids the need for multiple manual operations of rotating.

[0058] When it is necessary to match with the lock catch surface part, the rotating head 1 is rotated to the first state alone, then the lock catch surface part is inserted, the lock cylinder 221 is abutted and matched with the stroke limiting of the seat body 21 to release the rotation restriction of the rotating head 1, so that the rotating head 1 is rotated to the second state, thereby completing the locking action. The complicated actions of pre-rotating the rotating part to match with the lock catch surface part, inserting the lock catch surface part and manually rotating the rotating head are avoided. Meanwhile, when the matching space with the lock catch surface part is small, the problem that the user cannot hold the rotating head 1 or the rotating head 1 cannot be rotated to the position due to the operation interference such as wearing gloves is avoided. The rotation restriction of the rotating head is released by abutting, and the rotating head is automatically rotated to the second state under the action of the torsion, which is convenient and reliable to operate.

[0059] And under the action of torsion to rotate to the target second state of the position of the stability, can effectively cooperate with the lock catch surface piece to complete the locking action, avoid manual operation of the rotating head 1 rotating position unstable, not rotating to the target position such as the vertical point, thereby causing no lock, rotating head slip out of the eye piece problem occurs.

Wherein the first clamping groove 2211 and the first limiting part 13 are correspondingly arranged in groups, and one group or two groups or more groups are arranged. Along the axial projection of the lock cylinder 221, the first clamping groove 221 is arranged at the position where the rotating head body 11 and the first section projection surface coincide in the first state; the elastic part 222 exists when the first limiting part 13 and the first clamping groove 2211 are embedded, which makes the rotating head 1 rotate from the first state to the second state;

[0061] Wherein the first limiting part 13 is arranged between the connecting part 12 and the first fitting surface 14, and the rotating head body 11 is connected with the connecting part 12, wherein the upper end of the seat is arranged towards the rotating head 1, specifically, the second fitting surface 210 is arranged on the upper end of the seat 21 and opposite to the first fitting surface 14;

[0062] The spring is connected with the connecting portion 12, and the spring has the functions of transmitting torque and preventing the rotating head 1 from being completely separated from the abutting surface of the seat 21 and moving outward, so that the overall stability is stronger. The connecting portion 12, the spring and the lock cylinder 221 are connected in layers outward, the first limiting portion 13 penetrates through the lock cylinder 221 and the seat 21 and is connected with the rotating head body 11 extending outward, the first clamping groove 2211 is arranged, and the rotating head 1 is provided with the first limiting portion 13, so that the rotating head body 11 is rotated and the first limiting portion 13 is embedded in the first clamping groove 2211, thereby forming a first state. When the rotating head 1 needs to be rotated to a second state, the lock cylinder 221 is abutted to move along the axial direction of the seat 21, and the rotating head 1 has a tendency to move along with the lock cylinder 221 due to the fact that one end of the connecting portion 12 is connected with the spring. At this time, the rotating head 1 is separated from the lock cylinder 221 due to the fact that the seat 21 limits the stroke of the rotating head 1, so that the first clamping groove 2211 and the first limiting portion 13 are in a separated state, thereby being separated from the locking end of the lock cylinder 221, so that the rotation of the rotating head 1 is released, and the rotating head 1 is rotated to the second state under the action of the torsion of the spring. The operation is simple and reliable. Meanwhile, the rotating head is in a first state of being limited to rotate in the lock cylinder 221, until the lock cylinder 221 is abutted to release the limitation of the rotating head, and the rotating head 1 is rotated to the second state. The user only needs to twist the rotating head 1 once to reset the rotating head 1 to the first state, and the rotating head 1 is rotated to the second state only by abutting, so that the operation is convenient and the rotating head 1 does not need to be rotated manually for multiple times. The rotation of the rotating head 1 is limited by embedding, and the operation is reliable and easy to realize. The rotating head 1 can complete the first state before being inserted into the lock surface, and after being inserted into the lock surface, the first clamping groove 2211 is separated from the first limiting portion 13 by abutting, so that the rotating head 1 is automatically rotated under the action of the torque transmission, the locking action is completed, and the operation is convenient.

The spring is arranged in the lock cylinder 221 to transmit torque to the connecting portion and limit the rotating head 1 from being completely separated from the lock cylinder 221. The lock cylinder 221 is movably connected with the seat 21, so that the lock cylinder 221 can be abutted to move in the seat 21, thereby making the rotating head 1 have a tendency to move. The seat 21 arranged outside the lock cylinder 221 is abutted to separate the lock cylinder 221 and the rotating head 1, so that the multiple components cooperate to complete the limiting action and the releasing action. The operation is simple and reliable. The rotating head 1 is separated by limiting the stroke to release the limitation of the rotating head 1, and the torque is transmitted by the spring, so that the response speed is fast and the operation is convenient.

[0064] The first slot body 211 is arranged on the outer periphery of the seat body 21, the lock core 221 is arranged with a contact block body 2213 movably connected with the first slot body 211, and the contact block body 2213 penetrates through the first slot body 211. Preferably, the contact block body 2213 penetrates through the first slot body 211 and extends to the outside, and the contact block body 2213 extending to the outside is convenient to be contacted, so that the lock core 221 is more convenient to drive; wherein the first slot body 211 and the contact block body 2213 are arranged in correspondence in groups, and one group or more groups are arranged, the lock core 221 is connected with the contact block body 2213, the contact block body 2213 penetrates through the first slot body 211, the initial state of the rotating head 1 is the first state, the contact block body 2213 can move in the state of being limited by the moving path of the first slot body 211 after being contacted, so as to drive the lock core 221 to move, the spring is connected in the lock core 221, the spring thus exerts a force on the connecting part 12 to generate a trend of axial movement, so that the rotating head 1 is in the state of being blocked by the seat body 21, the rotating head 1 is separated from the lock core, so that the rotating head 1 rotates to the second state under the torsional force of the spring.

[0065] The seat body 21 is arranged with a second clamping point 212 corresponding to the end of the rotating path of the first limiting part 13. The projection of the first clamping groove 2211 and the second clamping point 212 in the axial direction of the lock core 221 does not overlap; along the axial projection of the trigger mechanism, taking the axis of the trigger mechanism 2 as the center, there is a certain angle X between a single first clamping groove 2211 and the second clamping point 212, wherein X is 90° in the technical solution, in the initial state, the direction of the torsional force release of the spring is from the first clamping groove 2211 to the second clamping point 212; preferably, the second clamping point 212 is arranged at an angle X of 90° between the first clamping groove and the axis as the center. Wherein the first clamping groove 2211 and the second clamping point 212 are arranged in correspondence in groups, and one group or two groups or more groups are arranged. The second clamping point 212 is arranged to limit the rotation angle of the first limiting part 13, so that the rotating head 1 rotates to the target second state with strong stability, and the problem that the rotation angle is too large to effectively cooperate with the lock catch surface to achieve the locking action can be effectively avoided. This arrangement mode has a certain fault tolerance for the torsional force of the spring, has more torsional force setting margin, reduces the production difficulty, and improves the use stability of the overall structure.

One end of the spring extends and extends into the second groove body 2214, and the second groove body 2214 is arranged to limit the spring in the circumferential direction when the rotating head is in the first state, that is, when the spring is twisted, so that the spring has a certain torsional force to be released. When the rotating head 1 needs to be rotated to the second state, the abutting block is abutted to drive the lock core 221, the movement of the lock core 221 drives the spring to exert a force on the connecting part 12 to make the rotating head 1 in the state of being blocked by the seat body 21, and the rotating head 1 is separated from the lock core 221, so that the rotating head 1 is rotated to the second state under the torsional force of the spring.

When the rotating head 1 needs to be rotated to the second state, the abutting block is abutted to drive the lock core 221, the movement of the lock core 221 drives the spring to exert a force on the connecting part 12 to make the rotating head 1 in the state of being blocked by the seat body 21, and the rotating head 1 is separated from the lock core 221, so that the rotating head 1 is rotated to the second state under the torsional force of the spring; and the bent part 2222 is arranged to effectively connect the connecting part 12 and the spring and improve the connection stability of the two.

[0068] The lock catch comprises a rotating mechanism, and further comprises a lock catch surface 3 sleeved with the outer periphery of the trigger mechanism and abutting against the trigger mechanism 2 to move to rotate the rotating head 1 to complete the locking action. The initial angle of the rotating head 1 is a first state, when the lock catch surface 3 abuts against the abutting block 2213 to move, the abutting block 2213 moves, the lock core 221 drives the first clamping groove 2211 to move, but the first abutting surface 14 of the rotating head 1 is blocked by the second abutting surface 210 to limit the stroke, the first limiting part 13 is separated from the first clamping groove 2211 to release the rotation limiting state, then the rotating head 1 is driven to rotate to a certain angle, i.e. a second state, under the torsion of the spring, and the second clamping point 212 is arranged to limit the rotation angle of the rotating head 1, and the rotating head 1 in the technical scheme rotates 90° as the target angle, the rotating head 1 after rotation limits the lock catch surface 3, avoids the lock catch surface 3 from being taken out of the outside, and thus completes the locking action in the pressing mode.

Specifically, the first through hole 31 is elliptical, the shape of the rotating head 1 is matched with the shape of the first through hole 31, and the projection area of the rotating head 1 is smaller than the projection area of the first through hole 31. This is the first state. Due to the different long and short sides, after the rotating head 1 rotates, a certain angle such as 90° is reached to form a second state. The long axis of the rotating head 1 intersects with the short axis of the first through hole 31, so the first through hole 31 cannot be pulled out from the rotating head 1; in the unlocked state, the long axis of the rotating head 1 is parallel to the long axis of the first through hole 31, so the axial direction movement of the first through hole 31 and the rotating head 1 is in a mutually non-interfering state.

[0073] The seat body 21 is sequentially provided with a first section 214 and a second section 215 along the axial direction of the trigger mechanism 2. The second clamping point 212 and the first groove body 211 are arranged on the first section 214. The abutting block 2213 penetrates the first section 214 and extends beyond the axial projection surface of the first section 214. The first groove body 211 is continuously arranged on the first section 214 and the second section 215. The abutting block 2213 penetrates the outer periphery of the second section 215 and has the same center with the outer periphery of the second section 215.

[0075] The lock catch surface 3 and the second gasket 32 are clamped with the second fabric 4 and hit together. The seat body 21, the lock core 222, the spring, and the rotating head 1 are sequentially assembled together. The connecting groove of the rotating head 1 fixes the four pieces. The first gasket 219 clamps the first fabric 5 and hits the first hitting foot 71 to fix it on the first fabric 5. The two modules are used by rotating the rotating head switch to complete the opening action of the bag or clothing.

[0076] The rotating assembly assembly method is as follows: first, the lock core 222 is sleeved into the seat body 21 from bottom to top, and the abutting block 2213 is clamped in the first groove body 211, which is a movable part; then the extension part 2221 of the spring is put into the second groove body 2214, and the second groove body 2214 fixes it; finally, the rotating head 1 is penetrated into the seat body from the opening on one side of the second clamping point 212, and the connecting groove 121 clamps the bending part 2222 above the spring put in before, and then the connecting groove 121 is hit and sealed, and the spring is clamped in the connecting groove 121, and the whole rotating head 1 is assembled.

[0077] The second material 4 is sandwiched between the locking face piece 3 and the second washer 32, and is struck together by the second striking foot 72 to form a hole piece. The assembled rotating head 1, base 1, lock cylinder 222, spring and first washer 219 are sandwiched between the first material 5 and are struck together by the first striking foot 71 to form a rotating piece. First, the hole piece and the rotating piece are mother and daughter parts. It is known that the rotating head of the rotating piece can just pass through the hole of the hole piece in its original state. After the rotating head rotates 90 degrees, it can just lock the hole piece so that it does not fall off.

[0078] Manually adjust the rotating head to... Figure 11 As shown on the left, the lock cylinder's abutment block 2213 contacts the second washer 32 of the entire eyelet component, which is the unlocked state. When the latch face 3 moves downward, causing the abutment block 2213 to move down until its bottom is parallel to the bottom of the seat 21, the spring's torque drives the rotating head to rotate 90° and automatically rebound to the set second locking point 212, thus locking it in place. This completes the rebound process, and the rotating head locks the eyelet component, preventing it from falling off. Figure 11 The status is shown on the right.

[0079] In this technical solution:

[0080] The base 21 is designed with two symmetrical second locking points 212, and the lock cylinder 222 is designed with two symmetrical first locking points 2212, and there are two first locking slots 2211 in the middle. When the block is engaged with the first slot 211, it forms...

When the bottom of the pressing block 2213 is on the same horizontal plane as the bottom of the seat 21, the spring rebounds, and the first limiting part 13 of the rotating head 1 is positioned above the first locking point 2212. The second locking point 212 blocks its rotation path, and at the Z-point position, the rotating head 1 is in a locked state. Figure 6 During this process, the spring is a special spring with different shapes at both ends. The protruding extension 2221 of the spring head is used to lock the second groove 2214, and the other end is locked into the connecting groove 121. Both ends are fixed, so that the locking point is reached by rotation, and then the force of the pressing part is used to return it to its original position.
