Abstract
The invention relates to an earphone tension adjusting mechanism. The earphone tension adjusting mechanism comprises two telephone receivers which are arranged symmetrically, wherein the telephone receivers are connected with each other through a U-shaped elastic plate; rotary seats are arranged on the telephone receivers; the rotary seats are rotationally connected with connecting rods; the connecting rods are provided with wire pass holes; a tensioning cable is inserted into the wire pass holes of the two telephone receivers; the two ends of the tensioning cable are provided with limiting blocks; a slide bar is arranged on the middle part of the tensioning cable; a plurality of transverse grooves are formed in the slide bar in an array form; two slide blocks are symmetrically arranged on the slide bar; the slide blocks are in sleeve connection with the slide bar; the inner walls of the slide blocks are provided with spring pieces; the spring pieces are provided with bosses; the bosses are clamped into the transverse grooves under the action of the elastic force of the spring pieces; and elastic rubber bars are arranged between the slide blocks and the connecting rods. The adjustment of the earphone clamping force and the distance between the telephone receivers is realized through a control mechanism for controlling the spread angle of the elastic plate, so that an earphone can be adjusted without influencing the comfort of the earphone.
Description
Technical field
The present invention relates to a kind of earphone governing mechanism of tension, belong to earphone and wear 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.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the earphone governor motion problem that comfort level can reduce regulating while in prior art, provide a kind of earphone governing mechanism of tension.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of earphone governing mechanism of tension, 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 is socketed with a rubber sleeve, one end of described tension cable is provided with a guide vane end stop, the other end of described tension cable is provided with a cable capstan winch, described cable capstan winch is fixed on connecting rod, described cable capstan winch comprises a shell be fixed on connecting rod, a bidirectional ratchet mechanism is provided with in described shell, described ratchet is provided with a moving block for solderless wrapped connection tension cable, described ratchet and shell are rotationally connected, the tooth engaged block be engaged mutually with described ratchet cylindrical ratchet is also elasticly connected with at described shell.
As further innovation of the present invention, described tension cable adopts wirerope to make.
As further innovation of the present invention, 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 invention, described elastic plate adopts corrosion resistant plate to make.
As further innovation of the present invention, the two ends of described elastic plate are embedded in two receivers respectively.
The invention has the beneficial effects as follows:
1, the present invention 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 the comfort level of earphone can not be had influence on while earphone regulates, the governor motion of sliding shoe formula uses easier simultaneously, elastic adhesive tape is not easy to twine hair compared to spring, and comfort is also higher.
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 present invention is further described.
Fig. 1 is generalized section of the present invention;
Fig. 2 is the partial enlarged drawing of A point in Fig. 1.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As depicted in figs. 1 and 2, the present invention is a kind of bindiny mechanism of headset earpiece 1, comprises two symmetrically arranged receivers 1, is connected between described receiver 1 by the elastic plate elasticity of a U-shaped, described elastic plate adopts corrosion resistant plate to make, and the two ends of described elastic plate 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 provided with a cable-through hole, the cable-through hole of described two receivers 1 is installed with a tension cable 3, described tension cable 3 adopts wirerope to make, described tension cable 3 is socketed with a rubber sleeve 4, one end of described tension cable 3 is provided with a guide vane end stop, the other end of described tension cable 3 is provided with a cable capstan winch 5, described cable capstan winch 5 is fixed on connecting rod 2, described cable capstan winch 5 comprises a shell be fixed on connecting rod 2, bidirectional ratchet 7 mechanism is provided with in described shell, described ratchet 7 is provided with a moving block 8 for solderless wrapped connection tension cable 3, described ratchet 7 is rotationally connected with shell, the tooth engaged block 6 be engaged mutually with described ratchet 7 cylindrical ratchet 7 is also elasticly connected with at described shell,
Described connecting rod 2 is tabular, described connecting rod 2 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.
By rotating ratchet 7, tension cable 3 is tightened up, thus promotion connecting rod 2 makes the spacing between two receivers 1 become large, thus reduce earphone to the clamping force of head;
If improve the clamping force of earphone to head, then rotate backward ratchet 7, make connecting rod 2 return under the effect of rubber sleeve 4, thus make the pitch smaller between receiver 1, clamping force increases.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
