Abstract
The utility model relates to an earphone clamp force adjustment mechanism, earphone including two symmetry settings, elastic plate elastic connection through a U -shaped between the earphone still be provided with a rotation seat on the earphone the rotation seat is gone up to rotate and is connected with a connecting rod it crosses the line hole to be provided with one on the connecting rod, a taut cable has been worn in the line hole of crossing of two earphones taut cable both ends are provided with a stopper be provided with a screw rod in the middle part of the taut cable the symmetry is provided with two stop nut on the screw rod be provided with the diastole spring between stop nut and the connecting rod, the utility model discloses a controlling the control mechanism who launches the angle between the elastic plate for one and realizing the adjustment to earphone clamp force and earphone interval, it itself does not exert an influence to the arc length between the earphone, so can not influence the comfort level of earphone when the earphone is adjusted.
Description
Technical field
The utility model relates to a kind of earphone clamping force governor motion, belongs to earphone and wears field of stents.
Background technology
Traditional large-scale and medium-sized earphone all adopts elastoplast plate or the clamping of steel plate realization to human body head, and the spacing of its clamping degree and receiver cannot regulate, and the sliding part that the spacing between traditional earphone is generally fixed on plastic plate or steel plate two ends holder by regulates, it mainly regulates the distance of receiver by the arc length increased between two earphones, the laminating degree of elastoplast plate or steel plate and human body head can be badly influenced, affect the comfortable wearing degree of earphone.
Utility model content
The technical problems to be solved in the utility model is: overcome the earphone governor motion problem that comfort level can reduce regulating while in prior art, provide a kind of earphone clamping force governor motion.
The utility model solves the technical scheme that its technical problem adopts:
A kind of earphone clamping force governor motion, comprise two symmetrically arranged receivers, connected by the elastic plate elasticity of a U-shaped between described receiver, described receiver is also provided with a rotation seat, described rotation seat is rotatably connected to a connecting rod, described connecting rod is provided with a cable-through hole, the cable-through hole of described two receivers is installed with a tension cable, described tension cable two ends are provided with a guide vane end stop, a screw rod is provided with in the middle part of described tension cable, described screw rod is symmetrically arranged with two stop nuts, diastole spring is provided with between described stop nut and connecting rod.
As further innovation of the present utility model, described connection cable adopts wirerope to make, and is welded to connect between the screw rod in the middle part of described connection cable and wirerope.
As further innovation of the present utility model, described connecting rod is tabular, described connecting rod is provided with a hollow hole, and in the middle part of described hollow hole, be fixedly connected with a dwang, described dwang and rotation seat are rotationally connected.
As further innovation of the present utility model, described elastic plate adopts corrosion resistant plate to make.
As further innovation of the present utility model, the two ends of described elastic plate are embedded in two receivers respectively.
The beneficial effects of the utility model are:
1, the utility model realizes the adjustment to earphone clamping force and receiver spacing by the controlling organization of expanded angle between a control elastic plate, itself does not have an impact to the arc length between receiver, so can not have influence on the comfort level of earphone while earphone regulates.
2, the connecting line durability of steel cable structure is good, is less likely to occur aging, and because the low draftability of wirerope itself, make earphone to wear rigidity better.
3, the connecting rod of tabular has better stability, makes connecting rod be not easy to bend at earphone horizontal direction, improves the stability of earphone.
4, the elastic plate durability of corrosion resistant plate material is good.
5, elastic plate adopts damascene structures, makes to be less likely to occur between steel plate and receiver to come off, and improves the durability of earphone.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is generalized section of the present utility model.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, the utility model is a kind of earphone clamping force governor motion, comprise two symmetrically arranged receivers 1, connected by elastic plate 8 elasticity of a U-shaped between described receiver 1, described elastic plate 8 adopts corrosion resistant plate to make, the U-shaped two ends of described elastic plate 8 are embedded in two receivers 1 respectively, described receiver 1 is also provided with a rotation seat, described rotation seat is rotatably connected to a connecting rod 2, described connecting rod 2 is tabular, described connecting rod 2 is provided with a hollow hole, a dwang is fixedly connected with in the middle part of described hollow hole, described dwang and rotation seat are rotationally connected, described connecting rod 2 is provided with a cable-through hole, the cable-through hole of described two receivers 1 is installed with a tension cable 6, described tension cable 6 two ends are provided with a guide vane end stop 7, a screw rod 3 is provided with in the middle part of described tension cable 6, described screw rod 3 is symmetrically arranged with two stop nuts 4, diastole spring 5 is provided with between described stop nut 4 and connecting rod 2,
Described connection cable adopts wirerope to make, and is welded to connect between the screw rod 3 in the middle part of described connection cable and wirerope.
By rotary stopper nut 4, thus change the pretightning force of diastole spring 5, diastole spring 5 promotes the pitch smaller that connecting rod 2 makes between two receivers 1, thus improves earphone to the clamping force of head;
If reduce the clamping force of earphone to head, then reverse rotation stop nut 4, the tension force of diastole spring 5 is diminished, thus make earphone only improve elastic plate 8 to be clamped in user's head.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
