Technical Field

The invention relates to the technical field of belt buckles, in particular to a belt buckle.

Background

The two most important types of belt buckles in the market are automatic buckles and pin eye buckles, in addition, a small number of smooth buckles are arranged, and the proportion of other types of belt buckles is small. The automatic buckle adopts a toothed belt body, and the needle eye buckle and the smooth buckle adopt a perforated belt body; the belt body with teeth and holes is generally thicker and harder, because the thicker belt body has space for designing the teeth and holes, particularly the tooth bars; hard to withstand the forces at the teeth and the hole, especially the eyelet; therefore, the belt body matched with the automatic buckle or the needle eye buckle or the smooth buckle is made of a thicker and harder material, and a thinner leather material cannot be singly used. In addition, the belt body is generally sandwiched in order to have sufficient rigidity. The belt body with the interlayer has thick and hard hand feeling, brings people a feeling like plastics generally, greatly covers the excellent characteristics of leather and cannot bring people comfortable use experience. For example, CN 210130442U discloses a buckle head with a pressing structure, which belongs to an automatic buckle and adopts a structure that a belt body is provided with ratchets (i.e. teeth strips).

Besides the three types of buckle heads, a buckle head suitable for a toothless and holeless belt body is available in the market, the toothless and holeless belt body can be made thin and soft, the original quality of leather can be kept to a great extent, and the comfort is greatly improved. For example, CN207653694U discloses a toothless belt buckle, which utilizes a double torsion spring and a clamping torsion spring to enable both a movable clamp and a tail clamp to be able to receive the elastic force of the spring and to automatically reset after rotating, so as to enhance the clamping effect of a clamping portion and avoid the loosening of the tail clamp to reduce the clamping effect of the movable clamp on a belt. But the clamping force of the spring is small when the spring is used, and the spring is likely to be loosened during use; in addition, the spring is likely to lose elasticity and be damaged after rusting after being used for a long time, and is inconvenient to replace; the thickness of the belt body is required to be high, the soft and thin pure belt material is not easy to use, and the comfort level is not high.

Therefore, it is desirable to provide a buckle head that can be used with belt bodies of various thicknesses and hardnesses.

In the embodiment, the locking tooth component is arranged at one end of the tail clamp 2, the clamping part is arranged at the other end of the tail clamp, and the latch member 5 in the locking tooth component is inserted and fixed in the tooth socket 4, so that the height of the locking tooth 52 relative to the tooth socket 4 can be adjusted according to the thickness and the material of the belt body to be used, the belt body is locked, a tooth bar or a punch is not required to be arranged on the belt body, a thicker belt body is not required to be adopted, for example, the belt body made of pure cowhide material can be adopted, the characteristics of leather material can be fully utilized, the comfort is brought to a user, the production process of the belt body can be reduced, and the cost is saved; the whole belt buckle has few parts and simple structure, reduces the whole weight, lightens the weight, ensures that the whole thickness of the buckle is consistent, ensures that the left thickness and the right thickness of the whole belt buckle are consistent when in use, avoids the left height and the right height, reduces the thickness and ensures that the thickness is consistent, is more fit with the body when in use, and improves the aesthetic degree; the buckle head and the tail clamp of the whole belt buckle can be thin, can be matched with a soft and thin belt for use, and is high in comfort.

In order to facilitate the adjustment of the latch 5, the adjusting member 6 is a bolt in this embodiment, the bottom of the socket 4 has a threaded hole, the bolt is disposed in the threaded hole, and the bottom of the latch 5 has a groove for receiving the top of the bolt. In the embodiment, the latch piece 5 can move up and down in the tooth socket 4 by rotating the bolt, so that the gap between the latch piece 5 and the buckle head 1 can be adjusted, and the belt body with different thicknesses can be locked and pursued by different users for the clamping force; in addition, no spring is arranged in the locking tooth assembly in the embodiment, so that the clamping force of the locking tooth assembly cannot be influenced even if the locking tooth assembly is used for a long time, and the service life of the locking tooth assembly is prolonged.

In order to facilitate the free end of the belt body to extend into the gap between the buckle head 1 and the latch 5 and to be rotationally locked, as a preferred embodiment, as shown in fig. 5, the tooth socket 4 in this embodiment is an inclined socket inclined toward the buckle head 1 (i.e., toward the right side), and the portion of the latch 5 inserted into the tooth socket 4 coincides with the inclined direction of the inclined socket. In the embodiment, the tooth socket 4 and the latch member 5 are inclined towards the buckle head 1, so that after the locking assembly is rotated and locked towards the buckle head, the engaging force between the locking assembly and the belt body is increased, and the locking degree is increased; on the other hand, the guiding locking is convenient in the rotating locking process, and the locked sensing information is provided for a user.

As shown in fig. 5, the locking teeth 52 in this embodiment are inclined teeth inclined toward the other end side of the tail clip, i.e., sufficient friction force is generated after locking with the belt body to increase the locking force. In addition, the locking teeth 52 are not fully distributed on the top plate 51, namely, the side edge of the top plate 51 close to the buckle head side is designed to be smooth, the smooth side edge of the top plate 51 does not participate in occlusion, but because the friction force between the right side edge of the top plate and the belt body is maximum when the buckle head is opened and closed, the smooth side edge can reduce the damage of the clamping tooth piece 5 to the belt body to a certain extent.

In the embodiment, the latch member 5 includes a top plate 51 and a supporting column 53, the locking tooth 52 is located on the surface of the top plate 51, the supporting column 53 is inserted into the tooth socket 4, and the top plate 51 covers the tooth socket 4. More preferably, the width of the top plate of the present embodiment is equal to the width of the tooth socket itself (i.e. the sum of the width of the inner cavity of the socket and the thickness of the two walls of the socket), so that the whole body is beautiful.

For better locking the belt body, the surface of the top plate 51 in this embodiment is a curved surface, which is consistent with the radian of the lower surface of the buckle head 1; this ensures that the locking teeth on the top plate 51 have the maximum engaging contact area with the button head 1.

In order to make the belt buckle integrally applicable, in the embodiment, the locking tooth assembly and the clamping part are positioned at two ends of the tail clamp 2, so that the clamping part and the locking tooth assembly are staggered from left to right and have dispersed thickness, the tail clamp is thinner, and the connecting shaft of the tail clamp and the buckle head is thinner; in addition, after the belt buckle is connected with the belt body, the gravity and the concentrated thickness of the belt buckle are dispersed at the clamping part and the locking tooth assembly, so that the phenomenon that the thickness of the belt buckle is concentrated at the connecting shaft of the tail clamp and the buckle head in the prior art is avoided, the connecting shaft is too thick, and the comfort is improved. In the embodiment, the tail clip 2 is rotatably connected with the buckle head 1, and the connection mode can be that a trunnion 21 is arranged on the inner side of the buckle head 1, a groove is arranged on the outer side of the tail clip, and the trunnion is inserted into the groove to realize rotary connection; the connection method is not limited to this, and only the two can be rotated relatively.

As shown in fig. 1 to 5, in the present embodiment, the clamping portion includes an open slot 23 into which the end portion of the belt body is inserted, and a locking bolt 3, a threaded hole 22 is provided on a slot wall below the open slot 23, and the locking bolt 3 is disposed in the threaded hole 22 and is used for being matched with an inner wall of the open slot 23 to lock the end portion of the belt body. The belt body is fixed through the open slot and the locking bolt, the open slot can be consistent with the thickness of the belt body, the height space does not need to be increased, the overall thickness of the tail clamp can be reduced, and the locking bolt 3 is more stable in fixing structure.

In the embodiment, the belt body can be made of pure leather, an interlayer or thickening and hardening treatment is not needed, and the thickness of the belt body is not limited; the belt body of the natural soft cowhide can be matched and used, so that the texture of the belt body is improved. The belt buckle of the embodiment is light, thin and close-fitting, high in comfort level and consistent in overall thickness, and the buckle head and the tail clip can keep consistent in overall thickness; in addition, the occlusion force can be adjusted by adjusting the adjusting piece 6, and the sliding buckle is avoided.

In summary, the belt buckle of the present invention has the locking tooth assembly disposed at one end of the tail clip, the clamping portion disposed at the other end of the tail clip, and the latch member of the locking tooth assembly inserted and fixed in the tooth socket, so that the height of the locking tooth relative to the tooth socket can be adjusted according to the thickness and material of the belt body, thereby achieving locking of the belt body. Therefore, the invention effectively overcomes various defects in the prior art and has high industrial utilization value.
