Embodiment 1

[0036] refer to Figure 1 to Figure 4 , a belt buckle, comprising a body 10, a board control body 20 and a pawl 13 for limiting the position of the belt body. The rear end of the main body 10 is provided with a belt clamping portion, and the front end of the main body 10 is connected with a rotating shaft 15 arranged in a left and right direction; the board control body 20 is fixedly connected with the rotating shaft 15 . The outer surface of the front end of the main body 10 is provided with a groove 11, the pawl 13 is located in the groove 11, the front end of the pawl 13 is fixed on the rotating shaft 15, and a As for the return spring 12, one return spring 12 is preferably used in this embodiment, and the number of return springs 12 can also be selected according to specific conditions.

[0037] refer to figure 1 with figure 2 , The outer surface of the body 10 is provided with a main limiting frame 16, and a belt body main penetration hole 25 opened in the front and r...

Embodiment 2

[0052] refer to Figure 12 with Figure 13 , The difference from Embodiment 1 lies in the difference between the pawl and the structure. In this embodiment, the pawl 13 is a convex arc-shaped pressing plate, and the outer surface of the arc-shaped pressing plate is provided with anti-skid lines 134 .

[0053] refer to Figure 12 to Figure 14 , in the belt corresponding to the ratchet 13 in this embodiment, the surface of the contact between the belt body 30 and the ratchet 13 is smooth, and the ratchet 13 is fixed to the belt body 30 through the anti-slip lines 134 . When wearing normally, the ratchet 13 is under the action of the return spring 12, and the part of the ratchet 13 with the anti-slip pattern 134 is pressed on the belt body 30; setting the anti-slip pattern can increase the friction between the ratchet 13 and the belt body, The belt is not easy to loosen during use; in this embodiment, the belt body 30 does not need to be provided with ratchets, and the manufact...

Embodiment 3

[0055] refer to Figure 15 , The difference from the second embodiment lies in the difference of the anti-skid pattern 134 of the ratchet 13; in this embodiment and in the second embodiment, the number of return springs 12 is preferably two, and can also be set as required.

Abstract

The invention provides a belt fastener, and solves the problem that a belt is inconvenient to unfasten since an existing automatic-fastening belt fastener is prone to being fastened excessively. The belt fastener comprises a body, a plate control body and a catch pawl used for limiting a belt body, a belt body clamping portion is arranged at the rear end of the body, a rotating shaft arranged in a left-right direction is rotatably connected to the front end of the body, an auxiliary penetrating hole is formed in the front end of the plate control body along a front-rear direction, the plate control body is fixedly connected with the rotating shaft, a groove is formed in an outer surface of the front end of the body, the catch pawl is positioned in the groove, the front end of the catch pawl is fixed on the rotating shaft, a reset spring is arranged between the rear end of the catch pawl and the rear end of a bottom portion of the groove, a main limiting frame is arranged on an outer surface of the body, and a main penetrating hole along the front-rear direction is formed between the main limiting frame and the outer surface of the body. The belt fastener has the advantages that tightness of the belt can be adjusted by pressing, and the belt fastener is enabled to be convenient to adjust and high in flexibility.

Description

technical field [0001] The invention relates to a belt buckle. Background technique [0002] At present, the working principle of the automatic locking belt buckle on the market is: when adjusting the tightness of the belt, press the belt buckle with the thumb, rotate the handle with the index finger, so that the rotating piece (pawl) is out of the ratchet, and the belt can be loosened freely or tighten up. When the belt is locked, the index finger leaves the handle, the rotating piece resets under the action of the magnet, and simultaneously the rotating piece leans against the ratchet. [0003] The existing self-locking belt buckle has the following disadvantages: first, it is cumbersome to adjust the tightness. When the belt is very tight, the rotating piece will be tightly buckled with the ratchet, and the handle is difficult to rotate. untie. Second, the structure is complicated and the quality is relatively heavy; the existing belt buckle has many parts and is easil...
