Abstract: An injection mold, including: an insert, a fixed half, a moving half and a core. The fixed half has a first groove and a rubber inlet communicating with the first groove. The moving half is configured for matching with the fixed half, the moving half has a second groove, and the fixed half and the moving half are arranged in layers to form a cavity together by the first groove communicating with the second groove. The core is partially embedded in the second groove and connected to the movable mold, the core has a diameter variable end at least partially located in the cavity. The insert is arranged on an end face of the diameter variable end, a first molding section is formed between the insert and a bottom of the first groove, the first molding section is configured for injection molding the flat portion.

Abstract: Provided is a cordless lamp including a housing, a light-emitting module, a switch, a button assembly, and a power supply. The housing defines a mounting cavity, and a sidewall of the mounting cavity is provided with a fitting hole. The light-emitting module is arranged in the housing and includes a circuit board and a light-emitting element arranged on the circuit board. The switch is arranged in the housing and electrically connected to the circuit board, and is used to control turning on and off of the light-emitting element and provided with a trigger surface. The button assembly includes a button and a protective cover. The button is inserted through the fitting hole, and one end of the button is operative to abut the trigger surface. The protective cover is sleeved on another end of the button, and abuts a sidewall of the housing. The power supply is arranged in the housing and electrically connected to the circuit board.

Abstract: Provided is a cordless lamp including a bottom housing, a cover housing, and a light-emitting module. The bottom housing has an open upper end, which is provided with a clamping groove and a snap ring arranged on an inner wall of the bottom housing. The cover housing has an open lower end, and is interlocked with the bottom housing. The cover housing is provided with a first and a second locking protrusion. The first locking protrusion is snap-fitted with the snap ring so that the open upper end of the bottom housing abuts an open lower end of the cover housing to form a first waterproof structure. The second locking protrusion is fitted with the clamping groove, and an adhesive is filled between the second locking protrusion and the clamping groove to form a second waterproof structure. The light-emitting module is arranged between the bottom housing and the cover housing.

Abstract: Disclosed are a lamp and a mining lamp The lamp includes a reflector, which is a spherical or bowl-shaped structure, an inner wall of the reflector is provided with a plurality of reflective layers in a honeycomb or scaly shape, each of the plurality of reflective layers includes a row of reflective surfaces arranged in the honeycomb or scaly shape, and all the rows of reflective surfaces are of surface reflection.

Abstract: A magnetically attachable wireless light emitting diode lamp includes a light emitting diode lamp assembly, a magnetic part (2) and a holding part (1). The light emitting diode lamp assembly is provided with buckles (4). The holding part is provided with buckling holes (3). The buckle (4) and the buckling hole (3) are matched and connected. The holding part (1) is provided with a recess structure at the center. The magnetic part (2) is matched with and mounted in the recess structure of the holding part (1). The magnetically attachable wireless light emitting diode lamp is simple in structure and convenient to install, and can be used under severe conditions. When a strong magnet is used, the magnetic force can reach 5 kgf or more. The magnetically attachable wireless light emitting diode lamp is both convenient and firm.
