Background

The belt buckles used by people today are basically classified into pin buckles, clip buckles and automatic buckles. The most common type is a pin buckle, which is based on the principle that positioning holes with equal intervals are punched on a belt, and a pin on the buckle is used for penetrating through the positioning holes to be fixed, so that the tightness of the belt is adjusted. The belt trimming device has the defects that the belt trimming device does not have a fine adjustment function, and the belt is easy to deform or damage at the positioning hole due to structural damage to the belt after long-term use. The clip is similar to the clip, and the nail head at the front end of the clip body penetrates through the hole on the belt to fix the belt, so that the belt is damaged, and the service life of the belt is influenced.

The automatic buckle has certain application because of the beautiful appearance and no influence on the belt. The existing automatic buckle product generally adopts a magnet or a spring control mechanism to control the opening and closing of the buckle body, and meanwhile, a gear structure is embedded into the belt buckle to be matched with the belt buckle for tightness.

Detailed Description

In order to better understand the technical solution of the present invention, the following detailed description is made by specific embodiments:

referring to fig. 1, the belt buckle of the present invention includes a belt buckle base 1, a belt buckle body 2 for connecting the belt buckle base and a belt buckle, and a locking assembly for locking a belt. The belt buckle body 2 is a common belt buckle body structure and is connected with the belt buckle seat 1 through a screw, and the technical key point of the patent is not achieved. The locking assembly comprises a diagonal eccentric shaft 3, an eccentric wheel 4, an eccentric shaft wrench 5 and a locking baffle 6.

Referring to fig. 2, the side walls of the two sides of the buckle seat 1 are respectively provided with a buckle body connecting hole 11, an eccentric shaft connecting hole 12 and a locking baffle connecting hole 13. And limiting platform structures 14 for limiting the rotation range of the inclined buckle eccentric shaft 3 are respectively arranged at two sides of the eccentric shaft connecting hole 12.

Referring to fig. 3, the inclined buckle eccentric shaft 3 is a slotted cylinder structure, the end structures 31 at two ends of the inclined buckle eccentric shaft are connected with each other through a section of cylinder wall, an eccentric shaft connecting through hole 32 is formed at the position of the axis of the end structure 31, a limiting structure 33 is arranged on the end structure 31, a pair of inclined buckle grooves 34 is formed at corresponding positions outside the eccentric shaft connecting through holes 32 of the two end structures 31, and a protruding eccentric shaft wrench clamping portion 35 is arranged on the end structure at one side of the inclined buckle eccentric shaft 3.

Referring to fig. 4, the eccentric wheel 4 is a cylindrical structure, and is disposed at the slot of the inclined buckle eccentric shaft 3 between the two end structures 31, and is provided with an eccentric wheel connecting through hole 41 at a position deviating from the axis along the axial direction, the aperture of the eccentric wheel connecting through hole 41 is smaller than that of the eccentric shaft connecting through hole 32, and the axis of the eccentric wheel 4 is provided with an inclined buckle through hole 42 matching the width of the inclined buckle slot.

Referring to fig. 5 to 7, the locking baffle 6 is a cylindrical structure, and has a locking baffle groove 61, a locking pin 62 is disposed therein, a locking pin connecting hole 63 is disposed on the locking pin 62, a locking wrench 64 having a locking wrench connecting hole 65 is connected to the locking pin 62 by a screw passing through the locking baffle groove 61, and the locking wrench 64 can drive the locking pin 62 to move telescopically within the locking baffle groove 61.

Referring to fig. 8, the eccentric shaft wrench 5 is divided into a connecting end and a locking end, the connecting end is provided with an eccentric shaft wrench engaging groove 53 matching with the eccentric shaft wrench engaging portion 35, the connecting end is provided with an eccentric shaft wrench through hole 52 for connecting the first connecting pin, and the locking end is provided with a locking pin engaging cover 51.

When the belt buckle is assembled, a first connecting pin penetrates through the eccentric shaft connecting hole 12, the eccentric shaft connecting through hole 32 and the eccentric wheel connecting through hole 41, so that the inclined buckle eccentric shaft 3 and the eccentric wheel 4 are connected with the belt buckle seat 1, and shaft seat cushions are arranged at two ends of the first connecting pin. Meanwhile, a second connecting pin penetrates through the inclined buckle groove 34 and the inclined buckle through hole 42, so that the eccentric wheel 4 can slide in the range of the inclined buckle groove 34 while rotating freely. The locking baffle 6 is fixed on the belt buckle seat 1 through a screw passing through the locking baffle connecting hole 13, and the end part of the locking pin 62 laterally extends out of one side of the belt buckle seat 1 when the belt buckle is in a locking state.
