Description

Technical Field

[0001] The invention belongs to the technical field of lock buckles, and in particular relates to a push lock buckle. Background Art

[0002] Luggage locks are a type of lock installed on bags or suitcases. Their main function is to protect the safety of items in the luggage. Luggage locks usually lock and unlock luggage through a buckle mechanism. The buckle is generally composed of a buckle head and a buckle body. The buckle head is responsible for locking the buckle body, and the buckle body is used to insert or unlock the buckle head. The overall size of the luggage lock is large, and the unlocking and product shape are relatively fixed and single. Generally, additional structures are added to unlock, lock downward, unlock sideways or in other directions, and it is impossible to complete the locking and unlocking operations in the same direction. Summary of the invention

[0003] The object of the present invention is to provide a push lock to solve the above-mentioned technical problems. The limit assembly extends into the female buckle, and the limit assembly cooperates with the locking assembly to perform a single press to interfere with and limit the limit assembly from being disengaged from the outside of the female buckle body, thereby completing the locking action. When unlocking is required, a second press is performed downward in the same direction as the first press to move the locking assembly and release the restriction on the limit assembly, so that the limit assembly can be disengaged from the outside of the female buckle body, thereby completing the unlocking operation. In the present technical solution, downward locking is adopted, and the unlocking is performed by pressing downward in the same direction at the same time, so as to achieve the effect that both push locking and push unlocking are performed in the same direction.

[0004] In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention is as follows:

[0005] A push lock includes a male buckle and a female buckle which are mutually locked by pressing once in the same direction and unlocked by pressing twice. The male buckle and the female buckle are locked after pressing once, and unlocked after pressing twice in the same direction. In this technical solution, downward locking is adopted, and unlocking is achieved by pressing downward in the same direction at the same time, so that the effect of pressing to lock and pressing to unlock is achieved in the same direction.

[0006] The male buckle includes a male buckle body, a limit component connected to the male buckle body and extending into the female buckle; the female buckle includes a female buckle body, a locking component arranged in the female buckle body and cooperating with the limit component to press once in the same direction to contact the limit and to move and release the limit after a second press. The limit component extends into the female buckle, and the limit component cooperates with the locking component to press once to contact and limit the limit component from coming out of the female buckle body, thereby completing the locking action; when unlocking is required, a second press is performed downward in the same direction as the first press, so that the locking component moves and releases the restriction on the limit component, so that the limit component can come out of the female buckle body, thereby completing the unlocking operation; in this technical solution, downward locking is adopted, and the unlocking is performed by pressing downward in the same direction at the same time, so as to achieve the effect that both the press-lock and the press-unlock are performed in the same direction.

[0007] Preferably, the limiting assembly includes a hook body connected to the male buckle body; the locking assembly includes a first limiting block body fixedly connected to the female buckle, and a second limiting block body arranged below the first limiting block body and capable of axially moving relative to the first limiting block body to cooperate with the hook body for locking and unlocking. The hook bodies are symmetrically arranged in groups, and the hook bodies extend into the interior of the female buckle and cooperate with the first limiting block body and the second limiting block body to perform locking and unlocking operations; the second limiting block body is initially located below the first limiting block body, and there is a space between the first limiting block body and the second limiting block body. When the male buckle is pressed, the male buckle moves and extends into the space between the first limiting block body and the second limiting block body, and the end of the hook body hooks the lower end face of the first limiting block body, so that the hook body cannot be disengaged from the opposite direction of the pressing, thereby completing the locking state of the male buckle and the female buckle; when unlocking is required, a second press is performed in the same direction, and the hook body moves axially in the space and contacts the upper end face of the second limiting block body, so that the hook body is stretched open, The hook body can be moved downward along the side of the second limit block. At this time, the locking mechanism cannot limit the hook body, and the hook body can move in the opposite direction of pressing. The movement of the hook body drives the second limit block body to move axially until the lower end surface of the first limit block body is in contact with the upper end surface of the second limit block body. The space between the first limit block body and the second limit block body is filled, and the hook body cannot be limited. Due to the continuous upward action of the hook body, the hook body moves to be in contact with the side surface of the first limit block body, thereby releasing the locking state of the male buckle and the female buckle; in this technical solution, downward locking is adopted, and the unlocking is achieved by pressing downward in the same direction at the same time, so that the effect of pressing to lock and pressing to unlock is achieved in the same direction.

[0008] Preferably, the first limiting block and the second limiting block are coaxially arranged.

[0009] Preferably, the locking assembly further comprises a fixing seat fixedly arranged inside the female buckle body, the fixing seat is fixedly connected to the first limiting block at one end facing the male buckle, and the outer periphery of the fixing seat is sleeved with the second limiting block. The fixing seat is coaxially arranged with the female buckle body; the first limiting block and the second limiting block are arranged vertically in sequence, and the second limiting block is prevented from falling out because the first limiting block is fixedly connected to the end face of the fixing seat. The first limiting block is connected to the fixing seat by screws; the fixing seat is arranged, and the end of the fixing seat is fixedly connected to the first limiting block, so that the first limiting block is in a fixed state; the outer periphery of the fixing seat is sleeved with the second limiting block arranged below the first limiting block, so that the second limiting block can move axially, and cooperate with the first limiting block to adjust the space between the two, thereby completing the limiting and non-limiting states of the hook body.

[0010] Preferably, the cross-section of the first limiting block and the second limiting block along the axial direction of the female buckle body is a trapezoid. The side surfaces of the first limiting block and the second limiting block are both inclined surfaces, so that when the hook enters the space between the first limiting block and the second limiting block, the length of the lower end surface of the first limiting block is larger, thereby limiting the hook; when the hook moves downward to the inclined surface of the second limiting block, the hook moves upward because the side surface of the second limiting block is an inclined surface, which facilitates the hook to drive the second limiting block to move axially, and the inclined surface facilitates locking and unlocking operations.

[0011] Preferably, along the axial direction of the locking assembly, the first limiting block is sequentially provided with a first end face and a second end face, and a first inclined face is provided between the first end face and the second end face;

[0012] The second limit block is provided with a third end face and a fourth end face in sequence, and a second inclined surface is provided between the third end face and the fourth end face. The second end face is provided opposite to the third end face, and when the first limit block and the second limit block are fitted, a trapezoid with two long sides fitting together is formed; when the male buckle is pressed once, the hook moves along the first inclined surface and is embedded in the space between the first limit block and the second limit block, thereby limiting the hook and completing the locking operation; when the male buckle is pressed twice in the same direction, the hook moves downward to the second inclined surface, and when the male buckle moves upward, due to the setting of the second inclined surface, the hook drives the second limit block to move axially until the first limit block and the second limit block fit together, so that no space for limiting the hook can be formed between the first limit block and the second limit block, and the hook body continues to move upward and conflicts with the first inclined surface, and the first inclined surface is arranged to be inclined upward toward the axis, and cannot limit the hook body, thereby failing to limit the male buckle, and completing the unlocking operation.

[0013] Preferably, along the radial direction of the locking assembly, the length of the first end face is less than the length of the second end face; the length of the second end face is equal to the length of the third end face, and the length of the third end face is greater than the length of the fourth end face.

[0015] Preferably, the fixing seat comprises a fixing platform coaxially fixedly arranged in the female buckle body, and a limiting column fixedly arranged on the fixing platform, wherein one end of the limiting column facing the male buckle is fixedly connected to the first limiting block, and the outer periphery of the limiting column is sleeved with the second limiting block;

[0016] The fixing platform is provided with a fifth end face on the side facing the male buckle; along the radial direction of the locking assembly, the length of the fifth end face is greater than the length of the fourth end face. The first limiting block is connected to the limiting column by screws;

[0017] Preferably, the hook body is movably connected to the male buckle body; the male buckle body is provided with an articulated seat hinged to the hook body, and the hook body is provided with an articulated column movably connected to the articulated seat;

[0018] A first spring is arranged in the male buckle body, one end of the first spring is connected to the upper end of the hook body at the hinge column, and the other end of the first spring is in conflict with the male buckle body. The first spring is arranged horizontally; the conflict between the male buckle body and the other end of the first spring is in the shape of an "I" character, wherein the hinge seat includes a base and a limit seat arranged above the base, and the hinge column is arranged between the limit seat and the base; wherein the connection between the hook body and the first spring is limited in the limit seat to avoid shaking; the first spring is arranged so that the end of the hook body away from the hinge column has a clamping force toward the axis of the male buckle body, so that when pressed once, the end of the hook body can enter the space between the first limit block and the second limit block, so that the end of the hook body hooks the lower end face of the first limit block, and at this time it cannot escape from the opposite direction of pressing; after pressing twice in the same direction, The hook body is stretched open to overcome the force of the first spring, and the end of the hook body moves to the side of the second limit block body. Since the hook body continuously clamps the second inclined surface and the second inclined surface is tilted downward toward the locking assembly, the second limit block body can be driven to move by the second inclined surface during the upward movement of the hook body, so that the second limit block body and the first limit block body are fitted together; so that no space for limiting the hook body can be formed between the first limit block body and the second limit block body, and the hook body conflicts with the first inclined surface after continuously moving upward. The first inclined surface is tilted upward toward the axis, and the hook body cannot be limited, thereby the male buckle cannot be limited, and the unlocking operation is completed.

[0019] Preferably, the hook body rotates with its end toward the center of the locking assembly with the hinge column as the rotation center; in the initial state, the length of the line between the end of the hook body and the center of the locking assembly is less than the length of the line from the edge of the second end surface to its center, but greater than the length of the line from the edge of the first end surface to its center.

[0020] Preferably, an elastic component is provided in the female buckle body to facilitate the hook body to be released from the limited state. The elastic component provides a continuous upward force to the male buckle, and when the male buckle and the female buckle are in the unlocked state, the hook body is convenient to move in the opposite direction of the pressing direction.

[0021] Preferably, the elastic component includes a second spring with one end restricted in the female buckle and a resistance ring connected to the other end of the second spring. The resistance ring is provided to provide a larger resistance area for the male buckle, and the force applied to the male buckle is more stable. At the same time, the resistance ring is connected to the second spring, and the second spring is provided parallel to the axial direction of the female buckle, so that the resistance ring has an upward thrust in the state of resistance;

[0022] Preferably, a connecting column is provided on one side of the abutment ring, and the outer periphery of the connecting column is sleeved with the other end of the second spring. A larger connecting surface is provided, so that the connection stability between the abutment ring and the second spring is stronger;

[0023] Preferably, the female buckle body is provided with a connecting groove, and the elastic component further comprises a connecting strip embedded in the connecting groove, and a connecting hole embedded and connected to one end of the second spring is provided on one side of the connecting strip facing the inside of the female buckle body. The connecting strip is connected to the fixing seat by a screw; when projected in the axial direction of the female buckle body, the connecting groove is in a through state at the position where the fixing seat is not provided, so that the end face of the connecting strip can be connected to the inside of the female buckle body. The connecting strip is embedded in the connecting groove, and the connecting strip is provided with a connecting hole connected to one end of the second spring, so that one end of the second spring is limited in the connecting hole, so as to prevent one end of the second spring from moving in the radial direction, thereby improving the connection stability of the second spring, so that when the elastic component is in a state of being resisted, the second spring can continuously apply force to the resisting ring.

[0024] Preferably, the female buckle body is provided with a limiting groove for limiting the axial travel of the interference ring; the interference ring is provided with an interference strip which can interfere with the limiting groove and thus prevent the interference ring from slipping out to the outside.

[0025] The second spring and the abutment strip are arranged in groups, and the connecting line of the axial projection passes through the center of the elastic component. Along the axial direction of the female buckle, the projection of the abutment strip overlaps with the projection of the limiting groove.

[0026] Preferably, the abutment ring is provided with an escape portion for the hook to pass through, so as to avoid the hook being unable to extend into the interior of the female buckle due to the existence of the abutment ring, and the hook passes through the escape hole and extends into the interior of the female buckle, thereby completing the locking action or the unlocking action, and improving the compactness of the overall structure.

[0027] Preferably, the male buckle body is provided with a contact end that can contact with the contact ring when connected with the female buckle body. The contact end is annular; a larger contact end is provided to improve the contact stability between the male buckle body and the contact ring, so that the second spring can effectively apply force to the contact end, so that the hook body can provide an upward force after the restriction is released, thereby facilitating the hook body to move upward.

[0028] Preferably, the female buckle body is provided with a cavity for the male buckle to be embedded, and the locking assembly is arranged in the cavity;

[0029] Along the radial direction of the female buckle, the inner diameter of the cavity is larger than the outer diameter of the abutment end. The elastic component is arranged in the cavity and coaxially arranged on the outer periphery of the locking component. The cavity is arranged to facilitate the insertion of the male buckle and then lock it. After the male buckle and the female buckle are locked, the inner surface of the cavity abuts against the outer surface of the abutment end, avoiding the problem of shaking between the male buckle and the female buckle and affecting the connection stability of the two.

[0030] Preferably, the male buckle body is provided with a through hole, and the end of the hook body away from the hinge column passes through the through hole and extends to the outside. The provision of the through hole can limit the rotation stroke of the hook body, so as to prevent the hook body from being too close to the axis of the male buckle body and being unable to move downward along the first inclined surface and open when inserted into the female buckle body;

[0031] Along the axial projection of the male buckle body, in the initial state, the vertical projection of the end of the hook body away from the hinge column overlaps with the first inclined surface.

[0032] Preferably, the male buckle body is provided with a first connection end that can be connected to the fabric; the first connection end includes a first thread connection post fixedly connected to the male buckle body, a first screw threadedly connected to the first thread connection post, and a first screw cover fixedly connected to the first screw. The first screw cover is provided to contact the fabric.

The second screw cover is provided to abut against the fabric.

[0034] This application has achieved beneficial technical effects:

[0035] The present invention extends a limit component into the female buckle, and the limit component cooperates with the locking component to perform a single press to interfere with and limit the limit component from being disengaged from the outside of the female buckle body, thereby completing the locking action; when unlocking is required, a second press is performed downward in the same direction as the first press, so that the locking component moves and releases the restriction on the limit component, so that the limit component can be disengaged from the outside of the female buckle body, thereby completing the unlocking operation; in this technical solution, downward locking is adopted, and the unlocking is simultaneously pressed downward in the same direction, so that the effect of pressing to lock and pressing to unlock is achieved in the same direction.

DETAILED DESCRIPTION

[0053] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0054] The technical solution of the present invention is described in detail below with specific embodiments.

[0055] like Figures 1 to 15 As shown, a push lock comprises a male buckle 1 and a female buckle 2 which are mutually locked by pressing once in the same direction and unlocked by pressing twice. The male buckle 1 and the female buckle 2 are locked after pressing once, and unlocked after pressing twice in the same direction. In this technical solution, downward locking is adopted, and unlocking is achieved by pressing downward in the same direction at the same time, so that the effect of pressing to lock and pressing to unlock is achieved in the same direction.

[0056] The male buckle 1 includes a male buckle body 11, a limiting component 12 connected to the male buckle body 11 and extending into the female buckle 2; the female buckle 2 includes a female buckle body 21, and a locking component 22 arranged in the female buckle body 21 and cooperating with the limiting component 12 to press once in the same direction to resist the limiting and to move and release the limiting after a second press. The limiting component 12 extends into the female buckle 2, and the limiting component 12 cooperates with the locking component 22 to press once to resist and limit the limiting component 12 from being disengaged from the outside of the female buckle body 21, thereby completing the locking action; when unlocking is required, a second press is performed downward in the same direction as the first press, so that the locking component 22 moves and releases the restriction on the limiting component, so that the limiting component 12 can be disengaged from the outside of the female buckle body 21, thereby completing the unlocking operation; in this technical solution, downward locking is adopted, and the unlocking is simultaneously pressed downward in the same direction, so that the locking and unlocking by pressing are both performed in the same direction.

[0057] The limiting assembly 12 includes a hook body 121 connected to the male buckle body 11; the locking assembly 22 includes a first limiting block body 221 fixedly connected to the female buckle 2, and a second limiting block body 222 arranged below the first limiting block body 221 and capable of axially moving relative to the first limiting block body 221 to cooperate with the hook body 121 for locking and unlocking. The hook bodies 121 are symmetrically arranged in groups, and the hook bodies 121 extend into the interior of the female buckle 2 and cooperate with the first limiting block body 221 and the second limiting block body 222 to perform locking and unlocking operations; the second limiting block body 222 is initially located below the first limiting block body 221, and there is a space between the first limiting block body 221 and the second limiting block body 222. When the male buckle 1 is pressed, the male buckle 1 moves and extends into the space between the first limiting block body 221 and the second limiting block body 222, and the end of the hook body 121 hooks the lower end face of the first limiting block body 221, so that the hook body 121 cannot be disengaged from the opposite direction of the pressing, thereby completing the locking state of the male buckle 1 and the female buckle 2; when unlocking is required, a second pressing is performed in the same direction, the hook body 121 moves axially in the space, and contacts the upper end face of the second limiting block body 222, so that the hook body The hook body 121 is stretched open so that the hook body 121 can move downward along the side of the second limit block 222. At this time, the locking mechanism 22 cannot limit the hook body 121, and the hook body 121 can move in the opposite direction of the pressing. The movement of the hook body 121 drives the second limit block 222 to move axially until the lower end surface of the first limit block 221 is in contact with the upper end surface of the second limit block 222, and the space between the first limit block 221 and the second limit block 222 is filled, and the hook body cannot be limited. Due to the continuous upward action of the hook body 121, the hook body 121 moves to be in contact with the side surface of the first limit block 221, thereby releasing the locking state of the male buckle 1 and the female buckle 2; in this technical solution, downward locking is adopted, and the unlocking is achieved by pressing downward in the same direction, so that the effect of pressing to lock and pressing to unlock is achieved in the same direction.

[0058] The first limiting block 221 and the second limiting block 222 are coaxially arranged.

[0059] The locking assembly 22 also includes a fixing seat 223 fixedly arranged inside the female buckle body 21, and the fixing seat 223 is fixedly connected to the first limiting block 221 at one end facing the male buckle 1, and the outer periphery of the fixing seat 223 is sleeved with the second limiting block 222. The fixing seat 223 is coaxially arranged with the female buckle body 21; the first limiting block 221 and the second limiting block 222 are arranged vertically in sequence, and the second limiting block 222 is fixedly connected to the end surface of the fixing seat 223 by the first limiting block 221, so as to prevent the second limiting block 222 from falling out. The first limiting block 221 is connected to the fixing seat 223 by screws; the fixing seat 223 is provided, and the end of the fixing seat 223 is fixedly connected to the first limiting block 221, so that the first limiting block 221 is in a fixed state; the outer periphery of the fixing seat 223 is sleeved with the second limiting block 222 provided below the first limiting block 221, so that the second limiting block 222 can move axially and cooperate with the first limiting block 221 to adjust the space between the two, thereby completing the limiting and non-limiting states of the hook body 121.

[0060] The cross-section of the first limiting block 221 and the second limiting block 222 along the axial direction of the female buckle body 21 is a trapezoid. The side surfaces of the first limiting block 221 and the second limiting block 222 are both inclined surfaces, so that when the hook 121 enters the space between the first limiting block 221 and the second limiting block 222, the length of the lower end surface of the first limiting block 221 is relatively large, thereby limiting the hook 121; when the hook 121 moves downward to the inclined surface of the second limiting block 222, the hook 121 moves upward. Since the side surface of the second limiting block 222 is an inclined surface, it is convenient for the hook 121 to drive the second limiting block 222 to move axially, and the inclined surface facilitates locking and unlocking operations.

[0061] Along the axial direction of the locking assembly 22, the first limiting block 221 is sequentially provided with a first end surface 2211 and a second end surface 2212, and a first inclined surface 2213 is provided between the first end surface 2211 and the second end surface 2212;

[0062] The second limiting block 222 is provided with a third end face 2221 and a fourth end face 2222 in sequence, and a second inclined surface 2223 is provided between the third end face 2221 and the fourth end face 2222. The second end face 2212 is arranged opposite to the third end face 2221, and when the first limiting block 221 and the second limiting block 222 are fitted together, a trapezoid with two long sides fitting together is formed; when the male buckle 1 is pressed once, the hook body 121 moves along the first inclined surface 2213 and is embedded in the space between the first limiting block 221 and the second limiting block 222, thereby limiting the hook body 121 and completing the locking operation; when the male buckle 1 is pressed twice in the same direction, the hook body 121 moves downward to the second inclined surface 2223, and when the male buckle 1 moves upward, due to Due to the setting of the second inclined surface 2223, the hook body 121 drives the second limiting block 222 to move axially until the first limiting block 221 and the second limiting block 222 are in contact with each other, so that no space for limiting the hook body 121 can be formed between the first limiting block 221 and the second limiting block 222. After the hook body 121 continues to move upward, it collides with the first inclined surface 2213. The first inclined surface 2213 is set to be inclined upward toward the axis, and cannot limit the hook body 121, thereby failing to limit the male buckle 1, thereby completing the unlocking operation.

[0063] Along the radial direction of the locking assembly 22, the length of the first end surface 2211 is less than the length of the second end surface 2212; the length of the second end surface 2212 is equal to the length of the third end surface 2221, and the length of the third end surface 2221 is greater than the length of the fourth end surface 2222. The first inclined surface 2213 is arranged upwardly and tilted toward the axis of the locking assembly; the second inclined surface 2223 is arranged downwardly and tilted toward the locking assembly.

[0064] Along the axial direction of the locking assembly 22, there is a freely movable space between the second end face 2212 and the third end face 2221. The fixing seat 223 is provided with a space for the second limiting block 222 to move. The second limiting block 222 can move along the axial direction of the fixing seat 223, thereby cooperating with the first limiting block 221 to lock or unlock the hook body 121.

[0065] The fixing seat 223 includes a fixing platform 2231 coaxially fixedly arranged in the female buckle body 21, and a limiting column 2232 fixedly arranged on the fixing platform 2231. The limiting column 2232 is fixedly connected to the first limiting block 221 at one end facing the male buckle, and the outer periphery of the limiting column 2232 is sleeved with the second limiting block 222.

[0066] The fixing platform 2231 is provided with a fifth end surface 2233 on one side facing the male buckle 1; along the radial direction of the locking assembly 22, the length of the fifth end surface 2233 is greater than the length of the fourth end surface 2222.

The hook body 121 is provided with an engaging column above the hinge column and engaged with one end of the first spring 14; the first spring 14 is arranged horizontally; the contact point between the male buckle body 11 and the other end of the first spring 14 is in the shape of an "I", wherein the hinge seat 13 includes a base 131 and a limiting seat 132 arranged above the base 131, and the hinge column 1211 is arranged between the limiting seat 132 and the base 131; wherein the connection between the hook body 121 and the first spring 14 is limited in the limiting seat 132 to avoid shaking; the first spring 14 is arranged so that the end of the hook body 121 away from the hinge column 1211 has a clamping force toward the axis of the male buckle body 11, so that when pressed once, the end of the hook body 121 can enter the space between the first limiting block 221 and the second limiting block 222, so that the end of the hook body 121 hooks the lower end surface of the first limiting block 221, and at this time it cannot be pressed from After the second pressing in the same direction, the hook body 121 is stretched open to overcome the force of the first spring 14, and the end of the hook body 121 moves to the side of the second limit block 222. Since the hook body 121 continues to clamp the second inclined surface 2223 and the second inclined surface 2223 is inclined downwardly arranged toward the locking assembly 22, during the upward movement of the hook body 121, the second limit block 222 can be driven to move by the second inclined surface 2223, so that the second limit block 222 and the first limit block 221 are fitted with each other; so that no space for limiting the hook body 121 can be formed between the first limit block 221 and the second limit block 222, and the hook body 121 continues to move upward and conflicts with the first inclined surface 2213. The first inclined surface 2213 is inclined upwardly arranged toward the axis, and the hook body 121 cannot be limited, thereby the male buckle cannot be limited, and the unlocking operation is completed.

[0069] The hook body 121 rotates with the hinge column 1211 as the rotation center and its end rotates toward the center of the locking assembly 22; in the initial state, the length of the line between the end of the hook body 121 and the center of the locking assembly 22 is less than the length of the line from the edge of the second end surface 2212 to its center, and is greater than the length of the line from the edge of the first end surface 2211 to its center.

[0070] The female buckle body 21 is provided with an elastic component 23 for facilitating the release of the hook body 121 in the restricted state. The elastic component 23 provides a continuous upward force to the male buckle 1, and when the male buckle 1 and the female buckle 2 are in the unlocked state, it is convenient for the hook body 121 to move in the opposite direction of the pressing direction.

[0071] The elastic component 23 includes a second spring 231 with one end restricted in the female buckle 2, and a resistance ring 232 connected to the other end of the second spring 231. The resistance ring 232 is coaxially arranged around the outer periphery of the locking component 22; the resistance ring 232 is arranged to provide a larger resistance area to the male buckle 1, and the force applied to the male buckle 1 is more stable. At the same time, the resistance ring 232 is connected to the second spring 231, and the second spring 231 is arranged parallel to the axial direction of the female buckle 1, so that the resistance ring 232 has an upward thrust in the state of being resisted;

[0072] A connecting column 233 is provided on one side of the abutment ring 232, and the outer periphery of the connecting column 233 is sleeved with the other end of the second spring 231. The connecting column 233 has a larger connecting surface, so that the connection stability between the abutment ring 232 and the second spring 231 is stronger;

[0073] The female buckle body 21 is provided with a connecting groove 211, and the elastic component 23 also includes a connecting strip 234 embedded in the connecting groove 211. The connecting strip 234 is provided with a connecting hole 2341 embedded and connected to one end of the second spring 231 on one side of the connecting strip 234 facing the inside of the female buckle body 21. The connecting strip 234 is connected to the fixing seat 223 by screws; when projected in the axial direction of the female buckle body 21, the connecting groove 211 is in a through state at the part where the fixing seat 223 is not provided, so that the end surface of the connecting strip 234 can be connected to the inside of the female buckle inner body 21. The connecting strip 234 is embedded in the connecting groove 211, and the connecting strip 234 is provided with a connecting hole connected to one end of the second spring 231, so that one end of the second spring 231 is limited in the connecting hole 2341, so that one end of the second spring 231 is prevented from moving in the radial direction, and the connection stability of the second spring 231 is improved, so that when the elastic component 23 is in a state of being resisted, the second spring 23 can continuously apply force to the resisting ring 232.

[0074] The female buckle body 21 is provided with a limiting groove 212 for limiting the axial travel of the abutment ring 232 ; the abutment ring 232 is provided with an abutment strip 235 that can abut against the limiting groove 212 to prevent the abutment ring 232 from slipping out to the outside.

[0075] The second spring 231 and the abutment strip 235 are arranged in a group, and the connecting line of the axial projection passes through the center of the elastic component 23. Along the axial direction of the female buckle 2, the projection of the abutment strip 235 overlaps with the projection of the limiting groove 212.

[0076] The abutment ring 232 is provided with an escape portion 236 for the hook body 121 to pass through. The escape portion is specifically a through hole; to prevent the hook body 121 from being unable to extend into the interior of the female buckle due to the existence of the abutment ring 232, the hook body 121 passes through the escape hole and extends into the interior of the female buckle 2, thereby completing the locking action or unlocking action, and improving the compactness of the overall structure.

[0077] The male buckle body 11 is provided with a contact end 15 that can contact the contact ring 232 when connected with the female buckle body 21. Along the axial direction of the male buckle body 11, the projection of the projection of the contact end intersects with the projection of the contact ring 232; the contact end 15 is annular; a larger contact end 15 is provided to improve the contact stability between the male buckle body 11 and the contact ring 232, so that the second spring 231 can effectively apply force to the contact end 15, so that the hook body 121 can provide an upward force after the restriction is released, thereby facilitating the hook body 121 to move upward.

[0078] The female buckle body 21 is provided with a cavity 213 for the male buckle 1 to be embedded, and the locking assembly 22 is arranged in the cavity 213;

[0079] Along the radial direction of the female buckle 2, the inner diameter of the cavity 213 is larger than the outer diameter of the abutment end 15. The elastic component 23 is disposed in the cavity 213 and coaxially disposed on the outer periphery of the locking component 22. The cavity 213 is provided to facilitate the insertion and locking of the male buckle 1. After the male buckle 1 and the female buckle 2 are locked, the inner surface of the cavity 213 abuts against the outer surface of the abutment end 15, thereby preventing the male buckle 1 and the female buckle 2 from shaking and affecting the connection stability between the two.

[0080] The male buckle body 11 is provided with a through hole 16, and one end of the hook body 121 away from the hinge column 1211 passes through the through hole 16 and extends to the outside. The provision of the through hole 16 can limit the rotation stroke of the hook body 121, so as to prevent the hook body 121 from being too close to the axis of the male buckle body 11 and being unable to move downward along the first inclined surface 2213 and open when inserted into the female buckle body 21;

[0081] Along the axial projection of the male buckle body 11 , in the initial state, the vertical projection of the end of the hook body 121 away from the hinge column 1211 overlaps with the first inclined surface 2213 .

[0082] The male buckle body 11 is provided with a first connection end 17 that can be connected to the fabric; the first connection end 17 includes a first thread connection post 171 fixedly connected to the male buckle body 11, a first screw 172 threadedly connected to the first thread connection post 171, and a first screw cover 173 fixedly connected to the first screw 172. The first screw cover 173 is set against the fabric.

[0083] The female buckle body 21 is provided with a second connection end 25 that can be connected to the fabric; the second connection end 25 includes a second thread connection post 251 fixedly connected to the female buckle body 21, a second screw 252 threadedly connected to the second thread connection post 251, and a second screw cover 253 fixedly connected to the second screw 252. The second screw cover 253 is set against the fabric.

[0084] The cross-section of the first limiting block is a trapezoid, and the two corners away from the second limiting block are rounded, and the two corners close to the second limiting block are non-rounded. Sharp angles are used in this technical solution to facilitate the positioning of the hook body; the cross-section of the second limiting block is a rounded trapezoid.

[0085] The technical solution discloses a push lock buckle, which is specifically applied to bags. Different from similar unlocking methods and block-shaped bag lock structures on the market, the technical solution adopts a downward locking and a structure design in which the user presses downward in the same direction to unlock the lock, and the user presses to open the lock buckle in one direction to unlock the lock.

[0086] The opening and closing of the lock is realized by the combination and elasticity of the first spring and the hook body. The hook body can be freely extended and retracted outwards under the action of the first spring with the hinge column as the fulcrum. The female buckle realizes the movement of the second limit block through the use of accessories such as the first limit block, the second limit block, the elastic component and the second spring, so as to achieve the effect of buckle buckling and unlocking.

[0087] The first screw cover and the second screw cover are combined with the fabric / leather material through screws;

[0088] Through the cooperation of the hook body and the first spring, and the hook body is buckled into the cavity of the female buckle, and the second spring and the connecting groove are cooperated, the hook body of the lock buckle can be clamped in the middle position between the first limit block and the second limit block. Fig.13 shown.

[0089] After the male buckle is installed, the hook body can freely extend and retract inward and outward. After the female buckle is assembled, the first limit block is fixed, and the second limit block can slide up and down. The first limit blocks are placed opposite to each other, the first limit block is inclined downward, and the second limit block is inclined upward, and the first limit block and the second limit block maintain a certain distance between the two components. When it is necessary to buckle, the male buckle is squeezed downward, and the hook body contacts the first inclined surface. Under the action of the first spring, the hook body of the male buckle slides downward with the inclination of the first limit block, and the hook body hooks the second end face, thereby achieving the purpose of locking the buckle; at this time, the male buckle and the female buckle are locked; when the male buckle and the female buckle need to be opened and unlocked, the male buckle continues to press down to a certain position and release it. When pressed down The hook body contacts the second limit block, and the outer periphery of the second limit block is a structure with a downward slope, and the upper mouth is the largest. When the hook body contacts the second limit block, the hook body opens under the action of the first spring force and hooks downward on the lower inclined surface of the second limit block. When the force is released, the hook body hooks the second inclined surface position of the second limit block, and the resistance ring rebounds upward under the action of the second spring. Under the action of this double force, the second limit block moves upward. When it moves to the first limit block and the second limit block are fitted, the gap between the first limit block and the second limit block is filled, and the hook body continues to move upward, opens under the action of the first spring force, and completely separates from the first limit block and the second limit block, thereby achieving the purpose of unlocking.
