A kind of dual-purpose adjustable earmuffs worn on the head and worn on the back

Abstract

The invention discloses head-mounted and rear-mounted dual-purpose adjustable earmuffs which comprise a U-shaped support, a left earmuff and a right earmuff. A U-shaped guide groove is formed inside the U-shaped support; a first ball plunger and a second ball plunger are respectively fixed to the left end and the right end of the U-shaped support in the horizontal direction; balls of the first ball plunger and the second ball plunger are positioned in the U-shaped guide groove; the left earmuff and the right earmuff are in structure bilateral symmetry with each other; the left earmuff comprises an adjusting connecting rod, a support seat and an earmuff body; a two-position adjusting groove is formed inside the support seat; the adjusting connecting rod is movably arranged in the two-position adjusting groove inside the support seat; the earmuff body is screwed on the right end surface of the support seat; the earmuff body is directional and can be divided into a front portion and a rear portion. The head-mounted and rear-mounted dual-purpose adjustable earmuffs have the advantages that a wearer can wear the head-mounted and rear-mounted dual-purpose adjustable earmuffs on the head or at the rear of the head, and the U-shaped support, the left earmuff and the right earmuff can be detached and separated from one another; the relative distances from the U-shaped support to the left earmuff and the right earmuff can be adjusted.

Description

technical field [0001] The invention relates to the technical field of life-warming products, in particular to a dual-purpose adjustable ear muff for head-wearing and back-wearing. Background technique [0002] In winter, when people are active outside, the cold air is very likely to cause people's ears to be cold and cracked, and even suffer from frostbite; therefore, it is necessary to wear earmuffs for protection. The existing earmuffs are generally made of cotton materials for keeping warm. The middle bracket is made, and the earmuffs are completely pressured by the middle bracket; and it is generally set as a head-mounted or a rear-mounted type, and the length cannot be adjusted and cannot be disassembled. [0003] The singleness of such setting reduces the wearing flexibility of the earmuffs and virtually wastes resources; meanwhile, it is not easy for consumers to choose and buy. Contents of the invention [0004] Aiming at the above technical problems, the present...

Problems solved by technology

[0002] In winter, when people are active outside, the cold air is very likely to cause people's ears to be cold and cracked, and even suffer from frostbite; therefore, it is necessary to wear earmuffs for protection. The existing earmuffs are generally made of cotton materials for keeping warm. The middle bracket is made, and the earmuffs are completely pressured by the middle bracket; and it is generally set as a head-mounted or a rear-mounted type, and the length cannot be adjusted and cannot be disassembled

[0003] The singleness of this setting reduces the wearing flexibility of the earmuffs and virtually wastes resources; at the same time, it is not easy for consumers to choose and buy.
