Description
Technical field:
The present invention relates to life warming article technical field, relate to the length-adjustable ear muff of a kind of gear type in particular.
Background technology:
Ear muff is that a pair is connected together for cold-proof screening ear thing by the metal tape of strap, elastic cord or softness.The structure of ear muff is very simple, primarily of support and protective sleeve composition.
Existing ear muff; that directly fixing cannot dismounting is saved with length key between its support and protective sleeve; after protective sleeve is damaged or pollutes; cannot disassembly, cleaning; just need, by whole replacing, to bother very much, and waste; and it cannot carry out the fine setting of length according to the people of different head dummy, thus cannot well wear on the user's head.
Summary of the invention:
The object of the invention is to overcome the deficiencies in the prior art, there is provided a kind of gear type length-adjustable ear muff, its warming guard shield and U-shaped support can dismounting and change, and the length of its U-shaped support can be finely tuned, the user meeting different head dummy uses, its convenient cleaning and replacing.
The scheme that the present invention solve the technical problem is:
The length-adjustable ear muff of a kind of gear type, comprise U-shaped support and warming guard shield, the vertical tooth bar upwards extended is provided with in described warming guard shield, in the jack that vertical tooth bar sleeve has at the two ends of U-shaped support, the sidewall of jack has groove, be hinged with regulating wheel in groove, the outer wall of regulating wheel has outer toothed portion, and outer toothed portion is meshed with vertical tooth bar;
Be fixed with banking stop in the upper medial wall of described groove or lower medial wall, banking stop holding is in the teeth groove of the correspondence of the outer toothed portion of regulating wheel.
Described warming guard shield comprises midfoot support contiguous block, the end face of midfoot support contiguous block has middle part jack, in the middle part of the bottom surface of middle part jack, there is the vertical tooth bar protruded upward, midfoot support contiguous block is in the inside of warming sponge block, the outside of warming sponge block is coated with warming leather sheath, the top of warming sponge block and warming leather sheath has the through hole communicated with middle part jack respectively, the end of U-shaped support through through hole and sleeve in the jack of middle part.
The two ends of described U-shaped support form insertion section, and insertion section is through through hole sleeve in the jack of middle part, and the end of the U-shaped support of the top of insertion section is pressed against on warming leather sheath, in the jack that vertical tooth bar sleeve has in the bottom of insertion section.
Have detent in the upper medial wall of described groove or lower medial wall, limited block is nested and be fixed in detent, and the end of limited block has banking stop, and banking stop stretches out detent.
Beneficial effect of the present invention is: compared with prior art, and its warming guard shield and U-shaped support can dismounting and change, and the length of its U-shaped support can be finely tuned, and the user meeting different head dummy uses, its convenient cleaning and changing.
Accompanying drawing illustrates:
The following drawings is only intended to schematically illustrate the present invention and explain, not delimit the scope of the invention.Wherein:
Fig. 1 is structural representation of the present invention;
Fig. 2 is partial enlarged drawing of the present invention.
Detailed description of the invention:
Embodiment, see as shown in Figure 1 to Figure 2, the length-adjustable ear muff of a kind of gear type, comprise U-shaped support 10 and warming guard shield 20, in described warming guard shield 20, be provided with the vertical tooth bar 21 upwards extended, in the jack 11 that vertical tooth bar 21 sleeve has at the two ends of U-shaped support 10, the sidewall of jack 11 has groove 12, be hinged with regulating wheel 13 in groove 12, the outer wall of regulating wheel 13 has outer toothed portion 131, and outer toothed portion 131 is meshed with vertical tooth bar 21;
Be fixed with banking stop 14 in the upper medial wall of described groove 12 or lower medial wall, banking stop 14 holding is in the teeth groove of the correspondence of the outer toothed portion 131 of regulating wheel 13.
Further, described warming guard shield 20 comprises midfoot support contiguous block 22, the end face of midfoot support contiguous block 22 has middle part jack 23, in the middle part of the bottom surface of middle part jack 23, there is the vertical tooth bar 21 protruded upward, midfoot support contiguous block 22 is in the inside of warming sponge block 24, the outside of warming sponge block 24 is coated with warming leather sheath 25, the top of warming sponge block 24 and warming leather sheath 25 has the through hole 26 communicated with middle part jack 23 respectively, the end of U-shaped support 10 through through hole 26 and sleeve in middle part jack 23.
Further, the two ends of described U-shaped support 10 form insertion section 15, insertion section 15 through through hole 26 and sleeve in middle part jack 23, the end of the U-shaped support 10 of the top of insertion section 15 is pressed against on warming leather sheath 25, in the jack 11 that vertical tooth bar 21 sleeve has in the bottom of insertion section 15.
Further, have detent 121 in the upper medial wall of described groove 12 or lower medial wall, limited block 141 is nested and be fixed in detent 121, and the end of limited block 141 has banking stop 14, and banking stop 14 stretches out detent 121.
By rotation two regulating wheels 13 of exerting oneself, thus realize vertical tooth bar 21 is moved downward or upward, thus regulate vertical tooth bar 21 to stretch into the distance of jack 11, realize the length of whole ear muff, and positioned in the teeth groove of the correspondence of the outer toothed portion 131 of regulating wheel 13 by banking stop 14 holding, it locates convenient, easy to adjust.
And shifted out from jack 11 completely by vertical tooth bar 21 and namely realize being separated of U-shaped support 10 and warming guard shield 20, its separation is quick and convenient, and part replacement is convenient.
Finally; above embodiment is only for illustration of the present invention; and be not limitation of the present invention; the those of ordinary skill of relevant technical field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification, therefore all equivalent technical schemes also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
