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.
Summary of the invention:
The object of the invention is to overcome the deficiencies in the prior art; there is provided a kind of length-adjustable earmuff detachable ear muff; its protection earmuff and thermal protection cover can dismounting and change; and its sponge cushion block also can be convenient for changing; and the adjustable in length of its U-shaped support; the user meeting different head dummy uses, its convenient cleaning and replacing.
The scheme that the present invention solve the technical problem is:
The detachable ear muff of a kind of length-adjustable earmuff, comprise U-shaped support and warming guard shield, described U-shaped support is the soft bar of silica gel, the two ends of U-shaped support are hinged with rotating screw bolt, the top of two connecting rods has adjustment screw, rotating screw bolt is screwed onto and regulates in screw, in the connection jack that connecting rod sleeve has at the top of warming guard shield, one medial wall of connection jack has the through hole that is spirally connected, the through hole that is spirally connected stretches out the lateral wall of warming guard shield, be spirally connected in through hole and be bolted with bulb plunger and bolted joint, bolted joint is near the lateral wall of warming guard shield, the steel ball of bulb plunger stretches into and connects jack and be nested in the shrinkage pool that the sidewall of connecting rod has, the medial wall of warming guard shield has stairstepping shrinkage pool, nested and be fixed with permanent magnetic iron block in the reduced diameter section of stairstepping shrinkage pool, the sidewall of sponge cushion block is fixed with iron plate, iron plate to be nested in the major diameter of stairstepping shrinkage pool and to be adsorbed on permanent magnetic iron block, another sidewall of sponge cushion block has the protection groove for placing ear, warming guard shield and sponge cushion block are all coated in thermal protection cover.
Corrugated rubber cover is inserted with, the top that the end of U-shaped support is put forth effort in upper end, connecting rod is put forth effort in lower end of corrugated rubber cover in described rotating screw bolt.
Nestedly in the multiple main shrinkage pool that the end face of described U-shaped support has be fixed with crystal ball.
Described thermal protection cover is the body that netted cloth is made, and the side of thermal protection cover has notch, and the edge of notch is provided with slide fastener.
Outstanding effect of the present invention is:
Compared with prior art, its protection earmuff and thermal protection cover can dismounting and change, and its sponge cushion block also can be convenient for changing, and the adjustable in length of its U-shaped support, and the user meeting different head dummy uses, its convenient cleaning and changing.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is partial enlarged drawing of the present invention;
Fig. 3 is the partial structurtes schematic diagram of thermal protection cover of the present invention.
Detailed description of the invention:
Embodiment, see as shown in Figure 1 to Figure 3, the detachable ear muff of a kind of length-adjustable earmuff, comprise U-shaped support 10 and warming guard shield 20, described U-shaped support 10 is the soft bar of silica gel, the two ends of U-shaped support 10 are hinged with rotating screw bolt 11, the top of two connecting rods 30 has adjustment screw 31, rotating screw bolt 11 is screwed onto and regulates in screw 31, in the connection jack 21 that connecting rod 30 sleeve has at the top of warming guard shield 20, one medial wall of connection jack 21 has the through hole 22 that is spirally connected, the through hole 22 that is spirally connected stretches out the lateral wall of warming guard shield 20, be spirally connected in through hole 22 and be bolted with bulb plunger 23 and bolted joint 24, bolted joint 24 is near the lateral wall of warming guard shield 20, the steel ball of bulb plunger 23 stretches into and connects jack 21 and be nested in the shrinkage pool 32 that the sidewall of connecting rod 30 has, the medial wall of warming guard shield 20 has stairstepping shrinkage pool 26, nested and be fixed with permanent magnetic iron block 27 in the reduced diameter section of stairstepping shrinkage pool 26, the sidewall of sponge cushion block 25 is fixed with iron plate 28, iron plate 28 to be nested in the major diameter of stairstepping shrinkage pool 26 and to be adsorbed on permanent magnetic iron block 27, another sidewall of sponge cushion block 25 has the protection groove 26 for placing ear, warming guard shield 20 and sponge cushion block 25 are all coated in thermal protection cover 40.
Further, in described rotating screw bolt 11, be inserted with corrugated rubber cover 50, the top that the end of U-shaped support 10 is put forth effort in upper end, connecting rod 30 is put forth effort in lower end of corrugated rubber cover 50.
Further, nestedly in the multiple main shrinkage pool that the end face of described U-shaped support 10 has crystal ball 60 is fixed with.
