Description

Technical Field

[0001] This utility model relates to the field of tail clip belt buckle technology, specifically a rotating tail clip belt buckle that can be detached from the front and rear. Background Technology

[0002] As a key component of a belt, the rotating tail clip belt buckle specifically refers to the device on the belt used to fix and adjust the tension. It is usually made of metal and is designed with two parts: a tail clip and a buckle. The tail clip is usually fixedly connected to the end of the belt, while the buckle is designed with a snap or sliding buckle mechanism to fit tightly with the tail clip, thereby fixing the belt at the desired tension.

[0003] Existing rotary tail clip belt buckles almost universally employ the traditional "integral stamping - forced bending" process in their manufacturing. This involves blanking the metal strip through a progressive die and then directly pressing the tail clip and buckle together in one step using a bending die. During this process, the high-pressure friction between the die and the workpiece easily scratches the surface plating. Due to the concentrated tensile and compressive stress in the bending area, micro-cracks, edge bursts, and even complete plating peeling often occur. Simultaneously, the material springback is extremely difficult to control precisely due to thickness tolerances, grain orientation, and die wear, resulting in significant batch-to-batch variations in bending angles and assembly gaps. This not only disrupts appearance consistency but also leads to a high rework and scrap rate. Furthermore, since the rotary tail clip and buckle are made as a single, non-separable structure, if any component deforms or has plating defects, the user must replace the entire buckle, resulting in severe deficiencies in economy and sustainable maintainability. Therefore, to address these issues, a rotary tail clip belt buckle with detachable front and rear ends is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a rotating tail clip belt buckle that can be detached from the front and rear, so as to solve the problem that the existing rotating tail clip belt buckles made by stamping and bending processes have various defects, and that once any part is damaged, the whole buckle must be scrapped and replaced.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A front-and-removable rotating tail clip belt buckle includes a front clip bottom cover, the front clip bottom cover including a lower cover assembly, the lower shell plate of the lower cover assembly having a pair of symmetrically arranged shaft grooves on the left side, the inner walls of the front and rear of the lower cover assembly having mating rails, the inner side of the lower shell plate of the lower cover assembly having a transversely arranged mating groove, a front tail clip front cover being installed inside the front clip bottom cover, the front tail clip front cover including an upper cover slidably connected to the pair of mating rails, the upper cover having a mating cavity on the right side, the left side of the mating cavity... The side opening has a through-hole, and the left side of the through-hole has slots on both the upper and lower sides. The left side of the through-hole has a notch, and the front and rear sides of the notch have hook grooves. The hook grooves and the shaft grooves are rotatably connected by a pin buckle. The right side of the front clamp bottom cover and the front tail clamp front cover is equipped with a rear tail clamp. The rear tail clamp includes a cover body that fits against the right end face of the upper cover. The left side of the cover body is fixedly connected with a mating protrusion tube. The front and rear sides of the cover body have mounting holes. The inner side of the rear tail clamp is equipped with a locking bolt, a spring, a nail, and a locking plate.

[0007] Preferably, the locking bolt is located inside the mating protrusion, and the left end of the locking bolt passes through the through-hole and engages with the slot. The locking bolt consists of a right bolt head, a middle connecting rod, and a left locking head. The left locking head of the locking bolt is located inside the slot. The spring is located between the right bolt head of the locking bolt and the left inner wall of the mating protrusion, and the spring is sleeved on the outside of the middle connecting rod of the locking bolt.

[0008] Preferably, the through-hole consists of a central hole and two side channels. The inner diameter of the central hole of the through-hole is the same as the diameter of the center connecting rod of the locking bolt, and the maximum width of the through-hole is greater than the height of the left locking head of the locking bolt.

[0009] Preferably, the mating cavity is located on the upper side of the mating groove, the length of the mating cavity is the same as the length of the mating protrusion, and the mating protrusion is inserted into the inner side of the mating cavity and the mating groove.

[0010] Preferably, nails are installed on the inner sides of the holes on both sides of the toothed plate. Each nail includes a magnetic block that fits against the inner wall of the hole in the toothed plate. A pin is fixedly connected to the outer side of the magnetic block. A rotating rod located inside the mounting hole is fixedly connected to the end of the pin away from the magnetic block. The toothed plate is a metal plate structure with a convex cone block that can be magnetically attracted.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this utility model, the front clamp bottom cover, front tail clamp front cover, rear tail clamp, and locking bolt are designed to position the pin buckle by fitting together. This allows the pin buckle to rotate freely while in position. The front clamp bottom cover, front tail clamp front cover, and rear tail clamp are locked together by the locking bolt and spring, ensuring a constant fit between them. The mounting plate can be installed inside the rear tail clamp using a nail, achieving a detachable design for the rotating tail clamp belt buckle. This design eliminates the drawbacks of traditional stamping and bending processes, allowing for targeted replacement of damaged components. It offers advantages in terms of economy and sustainable maintenance, solving the problem that existing rotating tail clamp belt buckles made using stamping and bending processes have various defects, and that any damaged component necessitates complete replacement.

[0030] Please see Figure 1-10 This utility model provides a technical solution:

[0031] A front-and-back detachable rotating tail clip belt buckle includes a front clip bottom cover 2, which includes a lower cover assembly 21. The lower cover assembly 21 has a pair of symmetrically arranged shaft grooves 22 on its left side. The lower cover assembly 21 has mating rails 23 on both the front and rear inner walls of its clamping body. The lower cover assembly 21 has a transversely arranged mating groove 24 on its inner side. A front tail clip front cover 3 is installed inside the front clip bottom cover 2. The front tail clip front cover 3 includes an upper cover 31 slidably connected to the pair of mating rails 23. The upper cover 31 has a mating cavity 32 on its right side and a mating groove 24 on its left side. The through-hole 33 has slots 34 on both the upper and lower left sides. The through-hole 33 has a notch 35 on the left side. The notch 35 has hook grooves 36 on both the front and rear sides. The hook grooves 36 and the shaft groove 22 are rotatably connected by a pin buckle 1. The front clamp bottom cover 2 and the front tail clamp front cover 3 are installed on the right side of the rear tail clamp 4. The rear tail clamp 4 includes a cover body 41 that fits against the right end face of the upper cover 31. The left side of the cover body 41 is fixedly connected to a mating protrusion tube 42. The front and rear sides of the cover body 41 have mounting holes 43. The inner side of the rear tail clamp 4 is equipped with a locking bolt 5, a spring 6, a nail 7 and a shim 8.

[0032] The locking bolt 5 is located inside the mating protrusion 42, and its left end passes through the through-hole 33 to engage with the slot 34. The locking bolt 5 consists of a right bolt head, a central connecting rod, and a left locking head. The left locking head of the locking bolt 5 is located inside the slot 34. The spring 6 is located between the right bolt head of the locking bolt 5 and the left inner wall of the mating protrusion 42. The spring 6 is sleeved on the outside of the central connecting rod of the locking bolt 5. This arrangement allows the front clamp bottom cover 2, the front tail clamp front cover 3, and the rear tail clamp 4 to be locked by the locking bolt 5 and the spring 6. The through-hole 33 consists of a central hole and two side channels. The inner diameter of the central hole of the through-hole 33 is the same as the diameter of the central connecting rod of the locking bolt 5. The maximum width of the through-hole 33 is greater than the height of the left locking head of the locking bolt 5. This arrangement allows the locking bolt 5 to pass through the through-hole 33. Cavity 32 is located on the upper side of mating groove 24. The length of mating cavity 32 is the same as the length of mating protrusion 42. The mating protrusion 42 is inserted into the inner side of mating cavity 32 and mating groove 24. This arrangement allows the front clamp bottom cover 2, front tail clamp front cover 3, and rear tail clamp 4 to fit together. Nails 7 are installed on the inner side of the holes on both sides of the shim plate 8. The nail 7 includes a magnetic block 73 that fits against the inner wall of the hole of the shim plate 8. A pin 72 is fixedly connected to the outer side of the magnetic block 73. A rotating rod 71 located inside the mounting hole 43 is fixedly connected to the end of the pin 72 away from the magnetic block 73. The shim plate 8 is a metal plate structure with a convex cone block that can be magnetically attracted. This arrangement allows the magnetic attraction of the magnetic block 73 to keep the nail 7 connected to the shim plate 8, thereby keeping the shim plate 8 installed in the rear tail clamp 4.

[0033] Workflow: The installation operation of the rotating tail clip belt buckle is as follows: First, place the front clip bottom cover 2 on the table. Then, place the rotating shaft of the pin buckle 1 on the shaft groove 22. Next, slide both ends of the front tail clip front cover 3 into the mating rails 23 on both sides of the front clip bottom cover 2 until the hook groove 36 of the front tail clip front cover 3 and the shaft groove 22 of the front clip bottom cover 2 mate to form a circular shaft hole. At this time, the mating groove 24 and the mating cavity 32 will also form an insertable pin groove. The installation of the front tail clip front cover 3 is completed through the above operations. The front clamp bottom cover 2 and the pin buckle 1 are assembled together. Then, the worker holds the rear tail clamp 4 and inserts its mating protrusion 42 into the insertable pin groove formed by the mating groove 24 and the mating cavity 32. At this time, the spring 6 can be placed on the outside of the middle connecting rod of the locking bolt 5. Using a screwdriver, the locking bolt 5 and the spring 6 are pushed into the mating protrusion 42 together, so that the left end of the middle connecting rod of the locking bolt 5 and the left clip pass through the mating protrusion 42 and the through hole 33. Then, the locking bolt 5 is rotated 90 degrees to release the lock. Bolt 5, when unfolded by the elastic force of spring 6, can push the locking bolt 5 to the right, causing the left locking head of the rotating locking bolt 5 to move to the right and insert into the slot 34. This completes the locking of the locking bolt 5, spring 6, front tail clip front cover 3, front clip bottom cover 2, and rear tail clip 4, thereby positioning the pin buckle 1 so that it can only rotate between the front clip bottom cover 2 and the front tail clip front cover 3. Finally, the mounting plate 8 is placed between the two mounting holes 43 on both sides. One end of the magnetic block 73 of the nail 7 is inserted into the hole of the mounting plate 8 through the two mounting holes 43 on both sides. The magnetic attraction of the magnetic block 73 keeps the nail 7 connected to the mounting plate 8, thus keeping the mounting plate 8 installed in the rear tail clip 4. The above operations complete the assembly of the rotating tail clip belt buckle. When disassembly is required, simply reverse the above operations. This achieves a detachable design for the rotating tail clip belt buckle. While eliminating the disadvantages of traditional stamping and bending processes, it allows for targeted replacement of damaged parts as needed, offering advantages in terms of economy and sustainable maintenance.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
