An anti-disassemble watch buckle includes a bottom housing and a top housing with an in-between space for accommodating a first strap, wherein the anti-disassemble watch buckle has a first end and a second end being opposite to the first end; and a cantilever snap with a back end fastened to the bottom housing at the first end, and a front end hung in the space.

A strap buckle structure includes a strap body. Two ends of the strap body are provided with an upper buckle piece and a bottom buckle piece. The bottom buckle piece is provided with a raised seat having a threaded hole. The upper buckle piece has a through hole and positioning holes. The strap buckle structure further includes a bolt having a turning disc, a spring, an annular iron seat, and a sealing plate. The annular iron seat is provided with positioning buckles each having a one-way bevel. The positioning buckles are controlled to be inserted into or disengaged from the positioning holes of the upper buckle piece. The turning disc is turned by hand. The bolt is screwed to lock the upper and lower buckle pieces. By using a tool having a magnetic rod to turn the turning disc reversely, the upper and lower buckle pieces can be opened.

A wearable electronic device assembly has a strap attached to the device for attaching the device to a wearer, and a connector for securing two overlapping end regions of the strap together. The connector has first and second parts configured to be secured together with the two overlapping end regions of the strap extending between them, to secure the two end regions together. The first part has a projection arranged to extend through or adjacent to the strap. The second part has a main body having an aperture to receive the projection of the first part, and a securement part movable with respect to the main body between a released position and a securement position. The projection is retained in the aperture to secure the first part of the connector to the second part of the connector.

A belt has a belt buckle and a belt strap. The belt can be part of a modular belt system that provides multiple straps and/or multiple buckles that can be assembled in different combinations. Preferably, the assembly of a custom belt can be accomplished in an in-store or point-of-sale environment. In some implementations, the strap can be coupled to the buckle without sewing or other processes that require expensive machinery and/or are time consuming. In some implementations, the strap is threaded to the buckle.

A belt has a strap defining a fixed end and a loose end and a buckle engaging the strap. The buckle has a frame defining a channel between outer and inner portions thereof and the outer portion extends beyond the lower portion. A prong protrudes from an undersurface of the outer portion into the channel to engage one of a series of holes of the loose end of the strap passing through the channel. The buckle also has a separable chape connecting the fixed end of the strap and which fits through a rear entrance of the channel to releasably connect to the inner portion of the frame.

A support belt (10) includes an elongate belt (12) having a dead end region (14) and a live end region (16) and buckling (18) to releasably connect the dead and live end regions (14,16) in a relaxed tightness condition of the support belt (10) and secure the dead and live end regions (14,16) in a tightened closed condition of the support belt (10) in which a free end (20) of the live end region (16) overlies a free end (22) of the dead end region (14). The buckling (18) comprises a first anchor portion (24) fixedly secured to the live end region (16), a second anchor portion (26) configured to releasably engage apertures (28) provided in the dead end region (14) and a locking mechanism (30) pivotally connected with the first and second anchor portions (24,26) and operable to draw the first anchor portion (24) towards the second anchor portion (26) to change the tightness condition of the support belt (10) from the relaxed tightness condition to the tightened closed condition.

A belt buckle with a replaceable insert is provided. The belt buckle includes a top cover, a bottom plate, a replaceable insert, and a base plate. The top cover includes a first recess. The bottom plate includes a first extruded portion extruding toward the top cover. The replaceable insert includes a second recess. The replaceable insert is disposed at least in part between the top cover and the bottom plate. The first extruded portion is disposed at least in part in the second recess.
