Description

Technical Field

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

[0002] Luggage locks are designed to be installed on bags or suitcases, primarily to protect the contents. These locks typically lock and unlock the bag through a buckle mechanism. The buckle typically consists of a head and a body. The head engages the body, while the body inserts and releases the head. Luggage locks are generally large, and their unlocking and design are relatively fixed. They typically require additional mechanisms for unlocking, locking downward, unlocking from the side, or unlocking in other directions, and cannot be locked and unlocked simultaneously. Utility Model Content

[0003] The purpose of the present utility model 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, so that the locking assembly moves and releases 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 this technical solution, downward locking is adopted, and unlocking is simultaneously achieved by pressing downward in the same direction, so that the push-locking and push-unlocking are both performed in the same direction.

[0004] In order to achieve the above-mentioned purpose of the utility model, the technical solution adopted by the utility model is as follows:

[0005] A push-lock buckle comprises a male buckle and a female buckle that lock each other with a single push in the same direction and release the lock with a second push. The male and female buckles lock with a single push and release the lock with a second push in the same direction, thus releasing the lock and releasing the lock. In this technical solution, downward locking and simultaneous downward unlocking in the same direction are employed, achieving the effect of both push-locking and push-unlocking in the same direction.

[0006] The male buckle includes a male buckle body, a limiting 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 limiting component to press once in the same direction to limit the position and to move and release the position after a second press. The limiting component extends into the female buckle, and the limiting component cooperates with the locking component to press once to limit the limiting component from being dislodged 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 limiting component, allowing the limiting component to be dislodged from the outside of the female buckle body, thereby completing the unlocking operation; in this technical solution, downward locking is adopted, and unlocking is simultaneously pressed downward in the same direction, so that the locking and unlocking operations are both 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 to lock and unlock. 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 to move axially until the lower end surface of the first limit block is in contact with the upper end surface of the second limit block. The space between the first limit block and the second limit block 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, 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 pressed downward in the same direction at the same time, so that the push-to-lock and push-to-unlock effects are 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, wherein 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 provided, 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 and second limiting blocks along the axial direction of the female buckle body is trapezoidal. The side surfaces of the first and second limiting blocks are both inclined, so that when the hook enters the space between the first and second limiting blocks, the lower end surface of the first limiting block is longer, thereby limiting the position of the hook; when the hook moves downward to the inclined surface of the second limiting block, the hook moves upward. Due to the inclined side surface of the second limiting block, the hook can easily 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 surface and a second end surface, and a first inclined surface is provided between the first end surface and the second end surface;

[0012] The second limiting 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 and the third end face are arranged opposite to each other, and when the first limiting block and the second limiting block are in contact, they form a trapezoid with two long sides in contact. When the male buckle is pressed once, the hook moves along the first inclined surface and fits into the space between the first limiting block and the second limiting block, thereby limiting the hook and completing the locking operation. When the male buckle is pressed a second time in the same direction, the hook moves downward to the second inclined surface. When the male buckle moves upward, due to the second inclined surface, the hook drives the second limiting block to move axially until the first limiting block and the second limiting block are in contact, so that no space for limiting the hook is formed between the first limiting block and the second limiting block. After the hook continues to move upward, it conflicts with the first inclined surface. The first inclined surface is arranged to be inclined upward toward the axis, and cannot limit the hook, thereby preventing the male buckle from being limited, completing the unlocking operation.

[0013] Preferably, along the radial direction of the locking assembly, the length of the first end surface is less than the length of the second end surface; the length of the second end surface is equal to the length of the third end surface, and the length of the third end surface is greater than the length of the fourth end surface. The first inclined surface is arranged upwardly and tilted toward the axis of the locking assembly; and the second inclined surface is arranged downwardly and tilted toward the locking assembly.

[0014] Preferably, a freely movable space exists between the second end face and the third end face along the axial direction of the locking assembly. The fixing seat is provided with space for the second limiting block to move. The second limiting block is movable along the axial direction of the fixing seat, thereby cooperating with the first limiting block to lock or unlock the hook body.

[0015] Preferably, the fixing seat includes 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 surface on the side facing the male buckle; along the radial direction of the locking assembly, the length of the fifth end surface is greater than the length of the fourth end surface. 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 a hinge seat hinged to the hook body, and the hook body is provided with a hinge column movably connected to the hinge seat;

[0018] A first spring is provided 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 provided above the base, and the hinge column is provided 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 provided 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 cannot be detached from the opposite direction of the 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 continues to clamp 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 in contact with each other; 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 continues to move upward and conflicts with the first inclined surface. 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 face to its center, and is greater than the length of the line from the edge of the first end face to its center.

[0020] Preferably, an elastic component is provided in the female buckle body to facilitate the release of the hook body from the restricted 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, it facilitates the hook body to move in the opposite direction of the pressing direction.

[0021] Preferably, the elastic component includes a second spring with one end confined within the female buckle and a contact ring connected to the other end of the second spring. The contact ring provides a larger contact area with the male buckle, making the force applied to the male buckle more stable. At the same time, the contact ring is connected to the second spring, which is arranged parallel to the axial direction of the female buckle, so that the contact ring has an upward thrust when in contact.

[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. The larger connecting surface makes the connection between the abutment ring and the second spring more stable;

[0023] Preferably, the female buckle body is provided with a connecting groove, and the elastic assembly further includes a connecting strip that engages within the connecting groove. A connecting hole is provided on one side of the connecting strip facing the interior of the female buckle body to engage with one end of the second spring. The connecting strip is connected to the fixing seat via a screw. Projected in the axial direction of the female buckle body, the connecting groove extends through the portion of the female buckle body where the fixing seat is not provided, allowing the end surface of the connecting strip to communicate with the interior of the female buckle body. The connecting strip engages within the connecting groove and is provided with a connecting hole for connecting to one end of the second spring. This constrains one end of the second spring within the connecting hole, preventing radial movement of the second spring end. This improves the connection stability of the second spring and allows the second spring to continuously apply force to the interference ring when the elastic assembly is in a state of interference.

[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 that can interfere with the limiting groove to prevent the interference ring from falling out to the outside.

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

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

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

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

[0029] Along the radial direction of the female buckle, the inner diameter of the cavity is greater than the outer diameter of the abutment end. The elastic component is disposed within the cavity and coaxially with the outer periphery of the locking component. The cavity facilitates insertion and locking of the male buckle. After locking, the inner surface of the cavity abuts the outer surface of the abutment end, preventing shaking between the male and female buckles that could affect the stability of the connection.

[0030] Preferably, the male buckle body is provided with a through hole, and the end of the hook body away from the hinge post extends through the through hole to the outside. The provision of the through hole can limit the rotational travel of the hook body, preventing 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] Projected along the axial direction 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 threaded post fixedly connected to the male buckle body, a first screw threadedly connected to the first threaded post, and a first screw cover fixedly connected to the first screw. The first screw cover is provided to contact the fabric.

[0033] Preferably, the female buckle body is provided with a second connection end that can be connected to the fabric; the second connection end includes a second threaded post fixedly connected to the female buckle body, a second screw threadedly connected to the second threaded post, and a second screw cover fixedly connected to the second screw. The second screw cover is provided to contact the fabric.

[0034] This application has achieved beneficial technical effects:

[0035] The utility model 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 restrict 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 unlocking is simultaneously achieved by pressing downward in the same direction, so that the effect of pressing to lock and pressing to unlock are 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 drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0054] The technical solution of the present utility model is described in detail below with reference to specific embodiments.

[0055] like Figures 1 to 15 As shown, a push-lock buckle includes a male buckle 1 and a female buckle 2 that 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 a single press, and unlocked after a second press 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, achieving the effect of push-locking and push-unlocking in the same direction.

[0056] The male buckle 1 includes a male buckle body 11, a limiting assembly 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 assembly 22 disposed in the female buckle body 21 and cooperating with the limiting assembly 12 to press once in the same direction to limit the position and to move and release the position after a second press. The limiting assembly 12 extends into the female buckle 2, and the limiting assembly 12 cooperates with the locking assembly 22 to press once to limit the limiting assembly 12 from the outside of the female buckle body 21, thereby completing the locking action; when unlocking is required, a second downward press is performed in the same direction as the first press, causing the locking assembly 22 to move and release the limit assembly, allowing the limiting assembly 12 to escape from the outside of the female buckle body 21, thereby completing the unlocking operation; in this technical solution, downward locking is adopted, and unlocking is simultaneously performed by pressing downward in the same direction, so that the locking and unlocking operations 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 escape from the opposite direction of 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, and 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 latch 221 is pressed against the second stop block 222, and the latch 221 is engaged with the second stop block 222, and the latch 221 is engaged with the second stop block 222.

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

[0059] The locking assembly 22 also includes a fixed seat 223 fixedly disposed within the female buckle body 21. The end of the fixing seat 223 facing the male buckle 1 is fixedly connected to the first limiting block 221, and the outer periphery of the fixing seat 223 is sleeved with the second limiting block 222. The fixing seat 223 is coaxial with the female buckle body 21; the first limiting block 221 and the second limiting block 222 are vertically arranged in sequence. Because the first limiting block 221 is fixedly connected to the end surface of the fixing seat 223, the second limiting block 222 is prevented from falling out. The first limiting block 221 is connected to the fixing seat 223 by screws; a 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 first and second limiting blocks 221, 222 have a trapezoidal cross-section along the axial direction of the female buckle body 21. The side surfaces of the first and second limiting blocks 221, 222 are both inclined, so that when the hook 121 enters the space between the first and second limiting blocks 221, the lower end surface of the first limiting block 221 is longer, thereby limiting the position of the hook 121. When the hook 121 moves downward to the inclined surface of the second limiting block 222, the hook 121 moves upward. Due to the inclined surface of the second limiting block 222, the hook 121 can easily 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 sequentially provided with a third end face 2221 and a fourth end face 2222, and a second inclined surface 2223 is arranged between the third end face 2221 and the fourth end face 2222. The second end face 2212 is oppositely arranged with the third end face 2221, and the first limiting block 221 and the second limiting block 222 are in abutment to form a trapezoid with two long sides in abutment; when the public 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 public buckle 1 is pressed twice in the same direction, the hook body 121 moves downward to the second inclined surface 2223, and when the public buckle 1 moves upward, 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 abutment, so that the space between the first limiting block 221 and the second limiting block 222 cannot limit the hook body 121, and the hook body 121 continuously moves upward and abuts against the first inclined surface 2213, which is arranged upward and inclined toward the shaft center, so that the hook body 121 cannot be limited, thereby the public buckle 1 cannot be limited, and the unlocking operation is completed.

[0063] In the radial direction of the locking assembly 22, the length of the first end face 2211 is less than the length of the second end face 2212; the length of the second end face 2212 is equal to the length of the third end face 2221, and the length of the third end face 2221 is greater than the length of the fourth end face 2222. The first inclined surface 2213 is arranged upward and inclined toward the shaft center of the locking assembly; and the second inclined surface 2223 is arranged downward and inclined toward the locking assembly.

[0064] In 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 fixed seat 223 provides a space for the movement of the second limiting block 222. The second limiting block 222 can move in the axial direction of the fixed seat 223, thereby cooperating with the first limiting block 221 to lock or unlock the hook body 121.

[0065] The fixed seat 223 includes a fixed table 2231 coaxially arranged in the female buckle body 21 and a limiting column 2232 fixedly arranged on the fixed table 2231. One end of the limiting column 2232 toward the public buckle is fixedly connected with the first limiting block 221, and the limiting column 2232 is sleeved with the second limiting block 222;

[0066] The fixed table 2231 is provided with a fifth end face 2233 on one side toward the public buckle 1. In the radial direction of the locking assembly 22, the length of the fifth end face 2233 is greater than the length of the fourth end face 2222. The first limiting block 221 is connected with the limiting column 2232 by a screw;

[0067] The hook body 121 is movably connected to the male buckle body 11; the male buckle body 11 is provided with a hinge seat 13 hinged to the hook body 121, and the hook body 121 is provided with a hinge column 1211 movably connected to the hinge seat 13;

[0068] A first spring 14 is disposed in the male buckle body 11 . One end of the first spring 14 is connected to the upper end of the hook body 121 where the hinge column 1211 is disposed. The other end of the first spring 14 contacts the male buckle body 11 . The first spring 14 is arranged to engage with the first spring 14 at one end of the first spring 14 and to engage with the first spring 14 at the other end of the first spring 14. The first spring 14 is arranged to engage with the first spring 14 at the other end of the first spring 14 and to engage with the first spring 14 at the other end of the first spring 14. The hinge seat 13 includes a base 131 and a limit seat 132 arranged above the base 131. The hinge post 1211 is arranged between the limit seat 132 and the base 131. The connection between the hook body 121 and the first spring 14 is limited in the limit seat 132 to prevent shaking. The first spring 14 is arranged to make the end of the hook body 121 away from the hinge post 1211 have 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 limit block 221 and the second limit block 222, so that the end of the hook body 121 hooks the lower end surface of the first limit block 221. At this time, it is impossible to press The first bevel 2213 is set upwardly and tilted 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 its end toward the center of the locking assembly 22 with the hinge column 1211 as the rotation center; 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 from 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 confined within the female buckle 2, and a contact ring 232 connected to the other end of the second spring 231. The contact ring 232 is coaxially arranged around the outer periphery of the locking component 22; the contact ring 232 provides a larger contact area with the male buckle 1, and the force applied to the male buckle 1 is more stable. At the same time, the contact 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 contact ring 232 has an upward thrust when in contact.

[0072] A connecting post 233 is provided on one side of the abutment ring 232, and the outer periphery of the connecting post 233 is sleeved with the other end of the second spring 231. The larger connecting surface makes the connection between the abutment ring 232 and the second spring 231 more stable;

[0073] The female buckle body 21 is provided with a connecting groove 211. The elastic assembly 23 also includes a connecting strip 234 that fits within the connecting groove 211. A connecting hole 2341 is defined on one side of the connecting strip 234, facing the interior of the female buckle body 21, for engaging one end of the second spring 231. The connecting strip 234 is connected to the fixing seat 223 via screws. In the axial direction of the female buckle body 21, the connecting groove 211 extends through the portion of the female buckle body 21 where the fixing seat 223 is not provided, allowing the end surface of the connecting strip 234 to communicate with the interior of the female buckle inner body 21. The connecting strip 234 fits within the connecting groove 211 and defines a connecting hole for connecting to one end of the second spring 231. This allows the end of the second spring 231 to be retained within the connecting hole 2341, preventing radial movement of the end of the second spring 231. This improves the connection stability of the second spring 231 and enables the second spring 23 to continuously apply force to the contact ring 232 when the elastic assembly 23 is in the contact state.

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

[0075] The second spring 231 and the contact 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 contact strip 235 overlaps with the projection of the limiting groove 212.

[0076] The interference ring 232 is provided with an escape portion 236 to facilitate the passage of the hook body 121. 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 presence of the interference 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 or unlocking action and improving the overall structural compactness.

[0077] The male buckle body 11 is provided with a contact end 15 that can contact the contact ring 232 when connected to the female buckle body 21. Along the axial direction of the male buckle body 11, the projection of the contact end intersects the projection of the contact ring 232. The contact end 15 is annular in shape. The larger contact end 15 improves the stability of the contact between the male buckle body 11 and the contact ring 232, allowing the second spring 231 to effectively apply force to the contact end 15, providing an upward force after the hook body 121 is released from restraint, thereby facilitating the upward movement of the hook body 121.

[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 provided in the cavity 213;

[0079] Along the radial direction of the female snap 2, the inner diameter of the cavity 213 is greater than the outer diameter of the abutment end 15. The elastic component 23 is disposed within the cavity 213 and coaxially arranged around the periphery of the locking component 22. The cavity 213 facilitates the insertion and locking of the pin 1. After the pin 1 and the female snap 2 are locked, the inner surface of the cavity 213 contacts the outer surface of the abutment end 15, preventing shaking between the pin 1 and the female snap 2, which could affect the stability of the connection.

[0080] The male buckle body 11 is provided with a through hole 16, and the end of the hook body 121, which is away from the hinge post 1211, extends outward through the through hole 16. The provision of the through hole 16 can limit the rotational travel of the hook body 121, preventing 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] Projected along the axial direction 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 post 1211 overlaps with the first inclined surface 2213 .

[0082] The male buckle body 11 is provided with a first connecting end 17 that can be connected to the fabric. The first connecting end 17 includes a first threaded post 171 fixedly connected to the male buckle body 11, a first screw 172 threadedly connected to the first threaded post 171, and a first screw cover 173 fixedly connected to the first screw 172. The first screw cover 173 is provided to contact 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 threaded post 251 fixedly connected to the female buckle body 21, a second screw 252 threadedly connected to the second threaded post 251, and a second screw cover 253 fixedly connected to the second screw 252. The second screw cover 253 is provided to contact the fabric.

[0084] The cross-section of the first limiting block is a trapezoid, and the two corners on the side away from the second limiting block are rounded, and the two corners on the side 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 trapezoid with rounded corners.

[0085] This technical solution discloses a push lock buckle, which is specifically used for luggage. Unlike similar luggage lock structures on the market that use a block-shaped unlocking method, this technical solution adopts a downward locking method and a simultaneous downward pressing method in the same direction to unlock. The push-open method is a structural design that locks and unlocks in one direction.

[0086] The lock is opened and closed through the combination and elasticity of the first spring and the hook. The hook, under the action of the first spring, can freely extend and retract outward with the hinge post as a fulcrum. The female buckle utilizes a first limit block, a second limit block, an elastic component, and a second spring to achieve the snap-on and unlocking effect by enabling the movement of the second limit block.

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

[0088] By cooperating with the hook body and the first spring, and buckling the hook body into the cavity of the female buckle, and cooperating with the second spring and the connecting groove, the hook body of the lock buckle can be clamped in the middle position between the first limit block and the second limit block. Figure 13 shown.

[0089] After the male buckle is installed, the hook body can freely stretch in and out, after the female buckle is assembled, the first limiting block body is in a fixed state, the second limiting block body can slide up and down, the first limiting block bodies are placed opposite to each other, the slope of the first limiting block body is downward, the slope of the second limiting block body is upward, and the first limiting block body and the second limiting block body maintain a certain distance, when it is necessary to buckle, the male buckle is pressed downward, the hook body contacts the first slope, under the action of the first spring, the hook body of the male buckle slides downward along the slope of the first limiting block body, the hook body hooks the second end surface, so that the locking purpose is achieved; 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 be pressed downward to a certain position and is released, when being pressed downward, the hook body contacts the second limiting block body, the outer periphery of the second limiting block body is a structure with a downward slope, the upper part is the largest, when the hook body contacts the second limiting block body, the hook body opens under the action of the first spring force and hooks the lower side slope of the second limiting block body, when the force is released, the hook body hooks the second slope position of the second limiting block body, the abutting ring rebounds upward under the action of the second spring, under the action of the double forces, the second limiting block body moves upward, when moving to the first limiting block body and the second limiting block body are attached, the gap between the first limiting block body and the second limiting block body is filled, the hook body continues to move upward and opens under the action of the first spring force, and completely separates from the first limiting block body and the second limiting block body, so that the unlocking purpose is achieved.
