Abstract: A belt buckle includes: an elastic member, a female buckle and a male buckle connected with different ends of lace. The female buckle includes a base provide with an insertion slot and a cover plate provided with a protrusion. The cover plate is mounted on the base and rotatable relative to the base. The male buckle includes an insertion block provided with a recess and a male buckle main body connected to the insertion block. When the insertion block is inserted into the insertion slot, and the protrusion extends into the recess, the female buckle and the male buckle are fastened together. When the cover plate is pressed to move towards the base, the elastic member press the cover plate to lift the cover plate in the direction away from the base to cause the protrusion to separate from the recess.

Abstract: Embodiments of the present application relate to the technical field of daily necessities, and in particular to a lock and a suitcase. The lock comprises: a lock main body, which is provided with an accommodating cavity, an opening, and a first through hole, and the opening and the first through hole both being in communication with the accommodating cavity; an elastic member, one end of which is fixed on the bottom of the accommodating cavity opposite the opening; and a clamping button, which comprises a button main body provided with a groove and a clamping boss obtained by extending from the button main body towards the groove, wherein the button main body is inserted into the accommodating cavity from the opening, the button main body is movable relative to the lock main body, the button main body abuts against the other end of the elastic member, and the clamping boss corresponds to the first through hole.

Abstract: An eyelet button and an assembly method thereof, in which the eyelet button is formed of an eyelet button body and a base plate for fastening with the eyelet button body. The eyelet button body is formed from an eyelet tube, a body peripheral portion formed by everything at one end of the eyelet tube in an axial direction, and a plurality of inverted fasteners formed by everting at the other end of the eyelet tube in the axial direction. The base plate is formed of a base plate body, with a mounting hole with an inner wall having a plurality of protruded tooth portions. A gap is formed between two adjacent protruded tooth portions. When the eyelet tube passes through the mounting hole, the inverted fasteners pass through the gaps to rotate with the eyelet tube so as to be connected and fixed to the corresponding protruded tooth portions.

Abstract: A connector assembly is formed from a female portion, a male portion and a locking cover. The female portion has a longitudinal channel with an opening and a slot that extends into the channel. The male portion has a locking post and an indentation that aligns with the slot when the post is inserted into the channel. The locking cover has a locking tooth that extends through the slot and into the channel. The male portion is connected to the female portion by sliding the locking post into the channel until the indentation aligns with the slot, so that the locking tooth rests in the indentation. The male portion is released from the female portion by pulling the locking cover away from the female portion until the locking tooth clears the indentation in the post which is mounted in the channel, and sliding the male portion and female portion away from each other.

Abstract: An attachable surface cover for a USB port has a casing and a base plate. The casing has an attachment component. The casing is attached to a piece of cloth by means of the attachment component penetrating through the cloth. The attachment component is detachably connected to the base plate. The attachable surface cover for a USB port has a plug hole for insertion and removal of a USB cable. An entrance of the plug hole is on the casing. An exit of the plug hole is used to configure a USB port. The attachable surface cover for a USB port of the present invention has a reasonable design and is highly practical.

Abstract: An adjusting strap adjusts the tube orifice diameter of a flexible tube-shaped object and has an inner annular wall, an outer annular wall, and an interlayer between the inner annular wall and the outer annular wall. The adjusting strap has a head portion, a tail portion, and a flexible rope strap portion between the head portion and the tail portion. The tail portion comprises a tail housing, and an avoidance hole passing through the tail housing and available for the head portion and the rope strap portion to pass through. When the adjusting strap is mounted in the flexible tube-shaped object, the head portion passes through the avoidance hole and penetrates the outer annular wall of the flexible tube-shaped object, the rope strap portion is partially received in the interlayer, and the tail portion is completely received in the interlayer and is connected to the flexible tube-shaped object.
