Description

Technical Field

[0001] The present application relates to a buckle. Background Art

[0002] A snap fit is a mechanism used to embed or integrally lock one part to another.

[0003] Currently, snap-fit ​​connections are commonly used to connect plastic parts, and are typically made of flexible plastic. The biggest advantage of snap-fit ​​connections is their ease of installation and removal, which can be achieved without tools.

[0004] In the process of implementing this application, the inventors found that there are at least the following problems in this technology: when the plastic buckles in the related technology are disassembled, they are mostly pressed. After the buckles are pressed repeatedly, the elasticity of the raw materials is easily reduced, making disassembly more inconvenient, so it needs to be improved. Summary of the Invention

[0005] In order to improve the problem in the related art that the buckle is easily inconvenient to disassemble by pressing, the present application provides a buckle.

[0006] The buckle provided in this application adopts the following technical solution:

[0007] A buckle comprises a locking part and a connecting part, the locking part is an internal hollow box structure, a locking hole is provided on the side wall of the locking part, a locking plate is provided on the inner side wall of the locking part, a connecting hole is penetrated by the locking plate, a pair of limit plates are rotatably connected to the inner side wall of the connecting hole, a rigid plate is provided on the side wall of the limit plate, one end of the rigid plate is connected to the side wall of the locking plate close to the locking hole, and the other end is connected to the limiting plate, the connecting part comprises an insertion rod and a limiting block, the insertion rod is inserted in the locking hole, the limiting block is provided at one end of the insertion rod inserted in the locking hole, a disassembly rod is provided on the side wall of the insertion rod, and the disassembly rod is against the side wall of the limiting plate.

[0008] By adopting the above technical solution, when the buckle in the present application is in use, the operator can hold the insertion rod, insert the insertion rod from the locking hole into the inside of the locking part, and insert the insertion rod from the connecting hole. At this time, the limit plate is opened and the insertion rod is inserted into the limit plate. Due to the deformation effect of the rigid sheet, when the limit plate insertion rod pushes the rod in the direction away from the locking hole, the rigid sheet will make the limit plate and the side wall of the insertion rod abut against each other, and then the insertion rod is rotated to complete the locking; when the operator needs to disassemble the buckle, the insertion rod can be rotated so that the disassembly rod can push the limit plate in the direction away from the locking hole, and then the operator can pull the insertion rod out from the connecting hole to complete the disassembly. The buckle in the present application is more convenient to disassemble than the buckle in the related art, which improves the convenience of the operator during installation and disassembly.

[0009] Optionally, a curved piece is provided on the end of the disassembly rod away from the insertion rod, and the straight-line distances from the end of the curved piece close to the disassembly rod and the end of the curved piece away from the disassembly rod to the insertion rod gradually increase.

[0010] By adopting the above technical solution, the structure of the curved piece allows the operator to rotate the insertion rod. Since the straight-line distance from the curved piece to the insertion rod increases, the curved piece can open the limit plate to facilitate the subsequent operator to remove the insertion rod from the locking hole, thereby improving the convenience of operation.

[0011] Optionally, a limiting groove is provided on the side wall of the limiting plate, the curved piece abuts against the side wall of the limiting groove, a guide surface is provided on the inner side wall of the limiting groove, and the guide surface is inclined toward the point where the curved piece abuts against the side wall of the limiting groove.

[0012] By adopting the above technical solution, the function of the limit groove is that when the insertion rod is inserted into the locking part, the curved piece can be fitted with the guide surface, so that during the locking process, the structure of the curved piece is relatively stable, thereby increasing the overall stability of the system; the function of the guide surface is that when the operator needs to disassemble the buckle, the curved piece can be pressed against and slide against the guide surface, thereby increasing the stability during the disassembly process.

[0013] Optionally, a protective sleeve rod is provided on the outer side wall of the insertion rod, and a return spring is provided on the inner side wall of the protective sleeve rod. One end of the return spring is connected to the protective sleeve rod, and the other end is connected to the insertion rod.

[0014] By adopting the above technical solution, the structure of the protective sleeve rod can protect the insertion rod after disassembly, so that the part of the insertion rod arranged outside the locking part is not easily damaged, thereby extending the service life of the insertion rod and increasing the overall service life of the system.

[0015] Optionally, an anti-displacement groove is provided on the side wall of the locking portion close to the locking hole, the anti-displacement groove is annular, the anti-displacement groove is coaxial with the locking hole, and the protective sleeve rod is inserted into the anti-displacement groove.

[0016] By adopting the above technical solution, the structure of the anti-displacement groove enables the insertion rod to be counteracted by the protective sleeve rod and the anti-displacement groove when the protective sleeve rod is inserted into the anti-displacement groove, thereby making it difficult for the insertion rod to move in the horizontal direction, thereby increasing the stability of the overall structure of the buckle when the buckle is locked.

[0017] Optionally, a stabilizing hole is provided on the side wall of the protective sleeve rod, a stabilizing spring is provided in the stabilizing hole, a stabilizing bead is provided at one end of the stabilizing spring away from the bottom wall of the stabilizing hole, an abutment hole is provided on the side wall of the anti-displacement groove, and the stabilizing bead is arranged to fit the inner wall of the abutment hole.

[0018] By adopting the above technical solution, the structure of the stabilizing bead further increases the stability of the protective sleeve rod when it is inserted into the anti-displacement groove, so that the protective sleeve rod is not easy to move in the horizontal direction when inserted into the anti-displacement groove, thereby increasing the stability of the contact between the protective sleeve rod and the locking portion, thereby improving the overall stability of the system.

[0019] Optionally, the interior of the stabilizing bead is hollow, and a collision ball is provided inside the stabilizing bead, and the collision ball is gap-fitted with the inner side wall of the stabilizing bead.

[0020] By adopting the above technical solution, the structure of the stabilizing bead and the collision ball makes it possible for the stabilizing bead to vibrate when the protective sleeve rod is inserted into the anti-displacement groove, thereby generating a collision sound between the collision ball and the stabilizing bead, thereby confirming that the stabilizing bead is inserted into the abutment hole, thereby reducing the possibility of unstable insertion of the protective sleeve due to the stabilizing bead not being inserted into the abutment hole.

[0021] Optional, including S1, snap connection to the object; S2, snap connection; S3, snap separation;

[0022] S1. Snap-fit ​​connection: the locking portion and the connecting portion are fixedly connected to the two parts to be connected respectively;

[0023] S2. Snap-fit ​​connection: The operator holds the two connecting objects, aligns the locking portion with the connecting portion, and inserts the connecting portion into the locking portion so that the insertion rod is locked between the limiting plates to complete the snap-fit ​​connection;

[0024] S3. Separation by snapping: When the two connected objects need to be separated, the operator can rotate the snapping part so that the curved piece opens the limit plate and then remove the snapping part from the connecting part.

[0025] By adopting the above technical solution, the operator can complete the connection between the fastened objects connected to the fastening part and the connecting part by inserting the locking part into the connecting part, and when the operator needs to disassemble it, it can be disassembled by rotating and pulling it away, which improves the convenience of operation.

[0026] Optionally, the locking portion, the connecting portion and the fastened object are all detachably connected.

[0027] By adopting the above technical solution, the structure in which the locking portion and the connecting portion are detachably connected makes it easy to perform partial replacement when the buckle has been used for too long, thereby reducing costs and improving operational convenience.

[0028] In summary, this application has at least one of the following beneficial effects:

[0029] When the lever is in the locking position, the operator can push the lever out of the locking hole and push the lever in, so that the locking plate can be locked.

[0030] 2. The curved piece structure is adopted. When the operator rotates the insertion rod, the straight-line distance between the curved piece and the insertion rod increases. Therefore, the curved piece can open the limit plate, making it easier for the operator to remove the insertion rod from the locking hole, thereby improving the convenience of operation.

[0031] 3. The structure of stabilizing beads and collision balls is adopted. When the protective sleeve rod is inserted into the anti-displacement groove, the stabilizing beads vibrate, thereby generating a collision sound between the collision ball and the stabilizing beads, so as to confirm that the stabilizing beads are inserted into the abutment hole, reducing the possibility of unstable insertion of the protective sleeve due to the stabilizing beads not being inserted into the abutment hole.
