Description

Technical Field

[0001] The invention relates to a belt buckle. Background Art

[0002] Traditional belt buckles are generally worn outside or inside, and cannot be compatible with both external and internal wear to meet the needs of users with different preferences; they cannot be compatible with both external and internal wear to meet the needs of the same user for internal and external wear due to different moods or environments and clothing combinations. Traditional hole-free and toothless belt buckles generally use springs, which are pressed in and fixed with rivets. They are difficult to disassemble and there is no space to replace springs of different specifications. It is difficult to meet the needs of different opening and closing forces and locking forces. Traditional belt buckles can only adapt to one type of belt and cannot meet the individual preferences for various types of belts. In summary, existing belt buckles are difficult to meet relevant requirements. Summary of the invention

[0003] The purpose of the present invention is to provide a multifunctional automatic belt buckle with low opening force, high locking force, high quality and beautiful appearance, which can be easily switched between inner and outer wear, and can easily replace spring pieces to provide different opening and closing forces and locking forces, and can also be equipped with multiple belts by conveniently replacing different types of locking parts to adapt to different types of belts, so as to meet people's demand for high-quality life.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme, which is composed of a buckle main part, a locking part, a rotating shaft, a spring piece, a guide plate, and a screw. The buckle main part is connected to the locking part through a rotating shaft, and then the spring piece is fixed to the locking part by a screw, and the guide plate is fixed to the buckle main part partition by a screw to form a belt buckle. It is characterized in that the front end of the buckle main part is provided with two ears, and the ears are provided with an axial hole, and the rear end is provided with a straight belt lock port and a belt outlet, and the partition between the two ports is provided with a belt lock screw hole; the upper surface of the locking part is provided with a belt lock tooth and a screw through hole, and the lower surface is provided with a screw hole, and the middle is bent to form an axial hole. The multifunctional belt buckle of the present invention only needs to disassemble and install 6 screws to conveniently switch to an inner wear type or an outer wear type. The multifunctional belt buckle of the present invention only needs to disassemble and install 1 screw to conveniently replace spring pieces of different specifications to provide different opening and closing forces and locking forces. The multifunctional belt buckle of the present invention can be matched with multiple belts with one buckle, and only needs to disassemble and install 3 screws to conveniently replace different types of locking parts to adapt to different types of belt bodies. Thanks to the new design of the lock, it has longer opening and locking torque than the traditional hole-less and toothless inner buckle, so it has low opening force and high locking force. At the same time, the handle without exposed outside is more beautiful. After the belt body is inserted, it can be reliably self-locked and non-slip. It is easy to tie and untie, and the tightness can be adjusted at will. In addition, the parts are optimized to facilitate low-energy, environmentally friendly, low-defect and high-quality product production.

[0005] Furthermore, the locking piece is designed to be U-shaped, with a locking tooth provided on its upper surface, the tooth tip angle is preferably less than 120 degrees, the upper surface has three screw holes, the lower surface has two protruding ears, the distance from the two ears to the shaft core is preferably more than twice the distance from the tooth tip to the shaft core, and the lower surface has three screw holes.

[0006] Furthermore, after the guide plate, spring sheet and locking member are removed by withdrawing the screw, the locking member can be installed in reverse, so that the belt buckle can be easily changed from being worn inside to being worn outside.

[0007] Furthermore, the front end of the spring piece is provided with a bend to press against the rotating shaft, and the bend is provided with a screw hole backwards, which is fixed to the locking part with screws. Spring pieces of different specifications can be easily replaced to provide different opening and closing forces and locking forces. The rear end is provided with a bend to avoid scratching the inner surface of the belt, and the end is inserted into the belt outlet.

[0008] Furthermore, the number of locking screw holes on the buckle main component partition is preferably three.

[0009] Furthermore, the guide plate is easy to disassemble and assemble. The front end is lower than the back of the buckle main component panel, there is a bend between the two ends, and a screw fixing hole is provided at the rear end. Together with the spring piece and the buckle main component, it forms a four-sided guide for the belt, and can be inserted at any angle and passed through in one go.

[0010] Furthermore, there is no need to disassemble the rotating shaft, and the locking parts with different tooth widths and tooth heights can be easily replaced by screwing screws, so that it can adapt to different types of belts on the market, such as holeless and toothless belts, toothed belts, and holed belts. One buckle can be matched with multiple belts.

[0011] Furthermore, the device can be used even without the spring sheet and the guide plate, after locking the limit shaft sheet or the screw, but it is more convenient and easy to use when they are not installed. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Specific test method

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. The described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without making any creative ideas are all within the scope of protection of the present invention.

[0023] Example 1

[0024] according to Figure 2 Align the rotating shaft with the shaft hole of the buckle main part, press the rotating shaft in, and face the tooth surface of the holeless and toothless belt lock fastener to the buckle main part. Insert it from the front of the buckle main part and put it on the rotating shaft. Turn the lock fastener 180 degrees, insert the front end of the spring piece into the gap between the teeth of the lock fastener and press it against the rotating shaft, and tighten the screws to fix it. Insert the front end of a 3.6cm thick holeless and toothless cowhide belt into the belt lock port of the buckle main part, insert the guide plate between the belt and the partition, adjust the guide plate screw through hole to align with the belt screw hole and the partition screw hole, and tighten the screws to fix the belt and the guide plate to the buckle main part. Turn the lock fastener to bend the spring piece, and insert the end of the spring piece into the belt outlet to complete the assembly. Figure 4 As shown. All parts of the buckle are made of stainless steel. After the belt is inserted, it is smooth and has no resistance. It is reliable and self-locking and non-slip, and easy to untie.

[0025] Example 2

[0026] Flip the inner-wearing belt buckle assembled in Example 1 over the buckle, remove the screws, take off the belt, guide plate, spring, and buckle, and then install the buckle in reverse. Insert the belt head into the buckle, align it with the screw hole, and tighten the screws to fix it. This can easily change the belt buckle from inner-wearing to outer-wearing. Figure 5 As shown, after the belt body is inserted, it can be reliably self-locked and non-slip, and it is easy to untie.

[0027] Example 3.

[0028] Flip the buckle of the inner belt buckle assembled in Example 1, remove the spring piece and the holeless and toothless belt buckle, install the toothed belt buckle and spring piece and screw them in place. Remove the screws and remove the holeless and toothless cowhide belt, replace it with the most common leather rubber tooth automatic belt body on the market, and insert the end of the spring piece into the belt outlet. The belt buckle can be easily changed from a holeless and toothless automatic belt buckle to a toothed automatic belt buckle. After the belt body is inserted, it can be reliably self-locked and non-slip, and it is easy to untie.
