The present invention provides a refrigerator, comprising a refrigerator body and a door body. A hinge body is disposed on the refrigerator body. A first hinge shaft and a second hinge shaft are disposed on the hinge body. A first guide groove and a second guide groove are formed in the door body. The first hinge shaft is located in the first guide groove and the second hinge shaft is located in the second guide groove. During opening of the door body, the first guide groove moves relative to the first hinge shaft and the second guide groove moves relative to the second hinge shaft, the first hinge shaft applies an acting force to the first guide groove to drive the end, away from the first guide groove, of the second guide groove to approach the second hinge shaft, so that the door body is displaced in a horizontal direction.

The present invention provides a refrigerator, comprising a cabinet, a door and a hinge body. A guide block is provided on the door, a rotation shaft is provided on the hinge body, and rotation shaft grooves are provided on the guide block. With the structure of the hinge body, the gravity of the door and the friction force may be shared onto the first and second plate bodies of the hinge body, thereby reducing abrasion and prolonging the service life of the door of the refrigerator.

A hinge includes a first hinge member including a first barrel, a second hinge member including a first end barrel opposite a second end barrel, a spring having a first axially extending end and a second axially extending end opposite the first axially extending end, a spring tensioner having a first depression for receiving the first axially extending end of the spring and a second depression for receiving a driver. A retainer is coupled to the spring tensioner and includes an opening that is penetrable by the driver when the driver is being received in the second depression. A method of adjusting the hinge includes compressing an end of the spring and twisting the same.

A pivot assembly includes a fixing base, a pivot portion, a center shaft, a compression spring and two hollow abrasion proof pieces. The fixing base is equipped with an isolating board defining a fixing hole. The pivot portion defines a pivoting hole in alignment with the fixing hole. The center shaft is inserted into the fixing hole and the pivoting hole. The compression spring is mounted around the center shaft. The two hollow abrasion proof pieces are sleeved around the center shaft. The two abrasion proof pieces are located between the isolating board and the pivot portion. The compression spring is located between the two abrasion proof pieces. An electronic device includes the pivot assembly.

A wireless blue-tooth earphone chargeable by a charging case, includes an earphone shell, an earplug assembled to a bottom of the earphone shell, a speaker unit, a circuit board assembly and a contact assembly. The earphone shell has an accommodating space penetrating through a lower portion of the earphone shell. One end of a peripheral surface of the earphone shell is recessed inward to form a recess. The speaker unit is accommodated in a front end of the accommodating space. The circuit board assembly is accommodated in a rear end of the accommodating space and is connected with the speaker unit. The circuit board assembly is equipped with a plurality of elastic elements. The contact assembly fastened in the recess, has a plurality of conducting elements. The plurality of the elastic elements are electrically connected with the plurality of the conducting elements.

A method of manufacturing a door hinge, which can improve productivity by applying both metal injection molding and additive manufacturing is disclosed. The door hinge includes: a first body configured to include at least one first connection member in which a first pinhole is formed; a second body configured to include at least one second connection member in which a second pinhole communicating with the first pinhole is formed; and a pin member configured to be added and filled in a cavity formed by communicating the first pinhole of the first body and the second pinhole of the second body with each other so that the first body and the second body are foldably connected to each other.
