Technical Field

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

Background

The Chinese character 'ri' buckle as a non-mainstream buckle head has the advantages of simple structure and attractive appearance, but is not greatly popularized because of the great limitation of the Chinese character 'ri' buckle. The first limitation is the clamping mode, the aim of clamping is achieved by the friction force between the belt body and the bar body, which is bent and arched, of the Chinese character 'ri' buckle, and the clamping mode is inconvenient to adjust the tightness, because if the friction force is large, the belt body is adjusted to be strong, and the friction force is small and the belt body is not clamped tightly; in addition, in the use process, as the belt body becomes soft, the arched radian is reduced, so that the tension is weakened, and the belt body is easy to slip due to long-term friction, so that the clamping purpose cannot be achieved; secondly, the whole buckle head is seriously unbalanced, because the Chinese character 'ri' buckle is not provided with an independent tail clamp, the belt tail is tied on the bar body, and the height of the left side is obviously higher than that of the right side; finally, because a plurality of belt tails are bound on the bar body in a sewing mode, the belt body cannot be cut, and the length of the belt body cannot be adjusted according to the self waist circumference.

Therefore, a new adjustment method is needed to solve the above problems.

Disclosure of Invention

In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a belt buckle, which solves the problems of time and labor consuming and untight clamping when adjusting the tightness of the belt in the prior art by using the friction force to clamp the belt.

To achieve the above and other related objects, the present invention provides a belt buckle, comprising:

the buckle head comprises an outer frame and a supporting rod arranged in the outer frame, wherein the supporting rod is provided with an auxiliary guide part, and the auxiliary guide part is a unidirectional rotating part with the rotating direction consistent with the belt body penetrating direction.

Preferably, the belt clamp still presss from both sides including the tail of fixed area body tip, the tail press from both sides with the frame is fixed to be linked to each other, the tail presss from both sides including supplying area body tip male open slot and locking bolt, the open slot is equipped with the screw hole on the cell wall that is in the below, locking bolt is arranged in the screw hole and is used for locking area body tip with the inner wall cooperation of open slot.

Preferably, the unidirectional rotating piece comprises ratchets arranged in the frame body, and the end part of the supporting rod is provided with a ratchet matched with the ratchet.

Preferably, the outer surface of the support rod has convex locking teeth.

Preferably, the unidirectional rotating member is a unidirectional bearing arranged on the supporting rod in a penetrating manner.

Preferably, the outer surface of the one-way bearing has a convex locking tooth.

Preferably, the support rod is connected with the outer frame in a sliding mode and is locked and positioned through the positioning piece.

Preferably, the outer frame is ring-shaped.

Preferably, the belt body is made of leather.

As described above, the belt buckle according to the present invention has the following advantageous effects:

1) the unidirectional rotating piece is used for unidirectional clamping, the rotating direction of the unidirectional rotating piece is consistent with the penetrating direction of the belt body, the belt can conveniently penetrate out of the buckle head, the belt can be conveniently pulled tightly, the belt is easy to adjust, the unidirectional rotation of the unidirectional rotating piece can prevent the belt from loosening rightwards, and the locking degree of the buckle head is improved; in addition, through the sliding arrangement of the supporting rods, when the belt becomes thin or is easy to slip due to long-term use, the locking force on the belt can be increased by enabling the supporting rods to slide leftwards;

2) the independent tail clamp is arranged, so that the phenomenon that the overall heights of the two sides of the bar body are inconsistent and the attractiveness and comfort are affected because the belt tail is tied to the bar body when the buckle head is not provided with the independent tail clamp is avoided; meanwhile, the problem that the belt body cannot be cut and the length of the belt body cannot be adjusted according to the waist circumference of the belt body due to the fact that the belt tail is directly sewn on the bar body is solved.

Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.

For convenience of description, the left-right direction in this specification refers to a direction that coincides with the left-right direction of the human body when the buckle is in use.

As shown in fig. 1 to 6, the present invention provides a belt buckle, including: the button head 1 comprises an outer frame 12 and a supporting rod 5 arranged in the outer frame 12, wherein the supporting rod 5 is provided with an auxiliary guide part, and the auxiliary guide part is a one-way rotating part with the rotating direction consistent with the belt body penetrating direction.

The belt buckle is clamped in a one-way mode through the one-way rotating piece, the rotating direction of the one-way rotating piece is consistent with the penetrating direction of the belt body, the belt can conveniently penetrate through the buckle head 1, the belt can be conveniently pulled in use, the locking degree of the belt can be adjusted, and the use comfort is improved.
