Embodiment Construction
[0019] exist figure 1 , figure 2 , image 3 , Figure 4 Among them, the upper buckle frame 1 is an inverted mountain-shaped structure composed of cross bars, left and right railings and middle support rods 3. The left and right railings and support rods 3 are parallel to each other. Between the railings are respectively provided with two left and right forward-rotating screw rods 2, and the left and right forward-rotating screw rods 2 are vertically connected with the transverse edge of the buckle frame 1 through the upper end, and the left and right forward-rotating screw rods 2 are arranged in parallel with the support rod 3. On the support rod 3 on the buckle frame 1, a longitudinal oblong hole 4 is provided, and the rear end of the lock column 7 is connected in the oblong hole 4 of the support rod 3, and the lock column 7 can be moved along the oblong hole 4 on the support rod 3. Moving up and down. The lower buckle frame 8 is a U-shaped structure composed of cross ba...

The invention provides a universal belt fastener suitable for belts of various widths. An upper fastener frame is of an inverted epsilon-shaped structure composed of a cross rod, a left railing, a right railing and a supporting rod in the middle. A left forward rotating screw rod and a right forward rotating screw rod are arranged on the two sides of the supporting rod respectively, and the rear end of a locking post is connected with the interior of a long round hole of the supporting rod. A lower fastener frame is of a U-shaped structure composed of a cross rod, a left railing and a right railing. The left railing, the right railing, a left reverse rotating screw rod and a right reverse rotating screw rod of the lower fastener frame correspond to the left railing, the right railing, the left forward rotating screw rod and the right forward rotating screw rod of the upper fastener frame respectively. Forward internal threads at the upper end of a left adjusting cylinder and at the upper end of a right adjusting cylinder are connected with the left forward rotating screw rod and the right forward rotating screw rod on the upper fastener frame respectively, and reverse internal threads at the lower end of the left adjusting cylinder and at the lower end of the right adjusting cylinder are connected with the left reverse rotating screw rod and the right reverse rotating screw rod of the lower fastener frame respectively. The upper fastener frame and the lower fastener frame are driven to be close or separated by rotating the adjusting cylinders. When the belt fastener is used, the tail of a belt penetrates out from the position between the left adjusting cylinder and the supporting rod and then penetrates in from the position between the supporting rod and the right adjusting cylinder, and the head of the belt penetrates out from the position among the upper right railings, the lower right railings and the right adjusting cylinder and then penetrates in from the position among the left adjusting cylinder, the upper left railings and the lower left railings.
Description
technical field [0001] The invention relates to a belt buckle, in particular to a universal belt buckle which can be applied to various wide and narrow belts by changing the geometric dimensions of the belt buckle. Background technique [0002] At present, the geometric dimensions of the known belt buckles are fixed, and belt buckles of different sizes need to be used for belts of different widths. Therefore, the conventional belt buckles have poor versatility. Contents of the invention [0003] In order to overcome the disadvantage of poor versatility of the existing belt buckles, the present invention provides a universal belt buckle, which can be adapted to belts of various widths by changing the geometric dimensions of the belt buckles. [0004] The technical solution adopted by the present invention to solve its technical problems is: the present invention comprises upper buckle frame, forward spiral screw rod, support rod, oblong hole, adjustment cylinder, reverse sp...
