Near infrared reading device and watchcase
Technical field
The present invention relates to a kind of near infrared reading device for electric energy meter and watchcase.
Background technology
Traditional near infrared reading device, its version is as Fig. 1: be fixed on inside meter shell of electric energy meter 1 in different ways or the top of the near-infrared luminous pipe in outside with the infrared sucker 2 that ferrous material makes, near infrared reading device 4 is equipped with magnet ring 3, when needs read data, the magnet ring of reading device is adsorbed on the infrared sucker of electric energy meter case.
Shortcoming: 1. cost is high, the infrared sucker on watchcase and the magnet ring in reading device all can increase the cost of product; 2. reading device volume is large, and heavy, magnet ring need have stronger magnetic, adds weight and the volume of reading device.
Summary of the invention
Technical matters to be solved by this invention is to provide the near infrared reading device that a kind of volume is little, lightweight, cost is low.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: near infrared reading device, comprises near infrared reading device body, and one end of described near infrared reading device body is fixed with magnetic post, and the other end is provided with data-interface.
As preferably, the end of described near infrared reading device body is provided with read head housing, is provided with reading module in described read head housing.
As preferably, the both sides of described read head housing are respectively provided with a lug, and each lug is provided with a groove, and this groove internal fixtion has a magnetic post.
As preferably, the center of top of described read head housing is provided with a boss.
As preferably, described data-interface is aviation plug or USB interface.
The watchcase matched with described near infrared reading device, described watchcase internal fixtion has iron prop, and described iron prop is corresponding with the position of described magnetic post and can be adsorbed on together.
As preferably, described watchcase inner central is provided with a locating slot.
As preferably, be provided with a stopper slot inside described watchcase, described locating slot is positioned within the bottom surface of described stopper slot.
As preferably, described iron prop is positioned at the both sides of described locating slot, and the outer face of described iron prop is concordant with the bottom surface of described stopper slot.
The present invention is owing to have employed technique scheme, and the infrared sucker iron prop 1. on watchcase replaces, and the magnetic post of the magnet ring near infrared reading device replaces, and can greatly reduce costs; 2. read head volume reduces, weight saving.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
Figure 2 shows that near infrared reading device embodiment of the present invention, described near infrared reading device comprises near infrared reading device body 4, one end of described near infrared reading device body 4 is fixed with magnetic post 3, the other end is provided with data-interface 5, in figure, watchcase 2 internal fixtion has iron prop 1, described iron prop 1 is corresponding with the position of described magnetic post 3 and can be adsorbed on together, and namely near infrared reading device is adsorbed by magnetic post 3 and the iron prop in watchcase.
As shown in Figure 3 and Figure 4, the end of described near infrared reading device body 4 is provided with read head housing 6, is provided with reading module 7 in described read head housing 6.The both sides of described read head housing 6 are respectively provided with a lug 61, and each lug 61 is provided with a groove, and this groove internal fixtion has a magnetic post 3, and as shown in Figure 5, in described watchcase 2, corresponding described magnetic post is provided with two iron props 1.The center of top of described read head housing 6 is provided with a boss 62, to being provided with a locating slot 22 by boss 62 inside described watchcase 2.Be provided with a stopper slot 21 inside described watchcase, described locating slot 22 is positioned within the bottom surface of described stopper slot 21.Described iron prop 1 is positioned at the both sides of described locating slot 22, and the outer face of described iron prop 1 is concordant with the bottom surface of described stopper slot 21.
Near infrared reading device of the present invention, the infrared sucker of irony on meter shell of electric energy meter makes iron prop into, iron prop can adopt the technology mode such as to be inlayed, heat is melted, be press-fitted and is fixed on meter shell of electric energy meter, magnetic post adopts press-fit to be fixed in the lug of read head housing, when needs read data, magnetic post is aimed at iron prop and can be attached together.The data-interface of the near infrared reading device body other end can adopt aviation plug, USB interface or other data-interface.
The compatible traditional near infrared reading device of watchcase near infrared place design and the near infrared reading device after improving, watchcase places the position of near infrared reading device, stopper slot is applicable to traditional near infrared reading device, and locating slot is applicable to the near infrared reading device after improving.On watchcase, the position of the former placement near infrared in the top of near-infrared luminous pipe sucker, changes iron prop into, and iron prop can adopt the mode such as to inlay, heat is melted, be press-fitted to be fixed on meter shell of electric energy meter, and the outer face of iron prop should flush with plastic surface, to strengthen suction.
Magnetic post replaces the magnet ring of traditional near infrared reading device, and magnetic post adopts the technology mode be press-fitted to be fixed on read head housing, and the volume of magnetic post is far smaller than magnet ring, and cost reduces greatly.Reading skull can be fixed with screw, and ultrasonic soldering, buckle, the alternate manner such as gluing also can be adopted to fix.Alignd with iron prop by magnetic post, read head housing head protruding parts is inserted in locating slot, can nearly easily be adsorbed on watchcase by infrared reading head device, reads data.Near infrared reading device after improvement is equally applicable to the ammeter of other band near infrared irony sucker.Data-interface can adopt aviation plug, USB interface or other data-interface.
