Its each part all can be changed, and it is convenient that its installation is dismantled, and its cold -proof guard shield can two -sidedly be worn in addition, and first recess and second recess variation in size in addition can satisfy not the ear of equidimension and wear extensive applicability.
Description
Technical field:
This utility model relates to life warming article technical field, relates to a kind of dismountable on both sides earmuff in particular.
Background technology:
Ear muff (earmuff) 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, directly fixingly between its support and protective sleeve cannot dismantle, after protective sleeve is damaged or pollutes, cannot disassembly, cleaning, and just need, by whole replacing, to bother very much, and waste.
And existing ear muff its can only simultaneously wear, also have one side to be can not wear outwardly, and everyone ear varies in size, and ear muff is excessive easily to leak out, and ear muff is too small to be with to enter again, and the ear muff that everyone is bought needs to try supporting could use.
Utility model content:
The purpose of this utility model overcomes the deficiencies in the prior art, a kind of dismountable on both sides earmuff is provided, its various piece all can be changed, its easy installation and removal, and its warming guard shield can two-sidedly be worn, and first groove and the second groove vary in size, the ear that can meet different size is worn, and the suitability is wide.
The scheme that this utility model solve the technical problem is:
A kind of dismountable on both sides earmuff, comprise U-shaped support and warming guard shield, the two ends of described U-shaped support are fixed with arc connection bracket, and the two ends of arc connection bracket are fixed on connecting axle, and connecting axle sleeve is in the center hub of warming guard shield; Described warming guard shield comprises central circular back-up block, the middle part of central circular back-up block has center hub, central circular back-up block is fixed on the middle part of circular sponge block, the both ends of the surface of circular sponge block have the first groove and the second groove, external coating is wrapped on circular sponge block outer wall, and the two ends of connecting axle are successively through circular sponge block and external coating.
Varying in size of described first groove and the second groove.
Be inserted with wear-resistant sleeve in the middle part jack of described central circular back-up block, the outer wall elasticity of wear-resistant sleeve is pressed against on the medial wall of middle part jack.
Described connecting axle sleeve is in wear-resistant sleeve.
The two ends of described connecting axle have radial direction and to be spirally connected through hole, double end bulb plunger is screwed onto radial direction and is spirally connected in through hole, two steel balls of double end bulb plunger stretch out radial direction and to be spirally connected through hole, the two ends of arc connection bracket have jack, the end of connecting axle is stretched in jack, and steel ball is nested in the shrinkage pool of the correspondence that the medial wall of jack has.
Outstanding effect of the present utility model is:
Compared with prior art, its various piece all can be changed, its easy installation and removal, and its warming guard shield can two-sidedly be worn, and the first groove and the second groove vary in size, and the ear that can meet different size is worn, and the suitability is wide.
Accompanying drawing illustrates:

Fig. 2 is side view of the present utility model;
Fig. 3 is the partial sectional view of warming guard shield;
Fig. 4 is the partial enlarged drawing of Fig. 2.
Detailed description of the invention:
Embodiment, see as shown in Figures 1 to 4, a kind of dismountable on both sides earmuff, comprise U-shaped support 10 and warming guard shield 20, the two ends of described U-shaped support 10 are fixed with arc connection bracket 30, the two ends of arc connection bracket 30 are fixed on connecting axle 1, and connecting axle 1 sleeve is in the center hub 21 of warming guard shield 20; Described warming guard shield 20 comprises central circular back-up block 22, the middle part of central circular back-up block 22 has center hub 21, central circular back-up block 22 is fixed on the middle part of circular sponge block 23, the both ends of the surface of circular sponge block 23 have the first groove 24 and the second groove 25, external coating 40 is wrapped on circular sponge block 23 outer wall, and the two ends of connecting axle 1 are successively through circular sponge block 23 and external coating 40.
Further, the varying in size of described first groove 24 and the second groove 25.
Further, be inserted with wear-resistant sleeve 26 in the middle part jack 21 of described central circular back-up block 22, the outer wall elasticity of wear-resistant sleeve 26 is pressed against on the medial wall of middle part jack 21.
Further, described connecting axle 1 sleeve is in wear-resistant sleeve 26.
Further, the two ends of described connecting axle 1 have radial direction and to be spirally connected through hole 11, double end bulb plunger 12 is screwed onto radial direction and is spirally connected in through hole 11, two steel balls of double end bulb plunger 12 stretch out radial direction and to be spirally connected through hole 11, the two ends of arc connection bracket 30 have jack 31, the end of connecting axle 1 is stretched in jack 31, and steel ball is nested in the shrinkage pool 32 of the correspondence that the medial wall of jack 31 has.
