Control unit controls the rotating forward of micro-step motor, and when it rotates forward, motor output shaft drives screw synchronous to turn
Dynamic, owing to mounting groove limits the rotation of latch segment, latch segment inwardly can only move linearly along mounting groove, lock
Tight block exits from positioning and locking groove, in latch segment is completely into mounting groove after, protective cover loses locking
The restriction of block, protective cover opens after automatically upspringing under the effect of torsion spring, and universal electric furnace just can be entered by user
Row operation;When rotary knob switchs, the rotating shaft of rotary switch gradually promotes bearing pin to be gradually backed out tortuous groove,
Along with the rotation of rotating shaft, bearing pin moves linearly along via and touches the meter on enumerator in the stroke set
Number switch, operation information and the operating time of this switch recorded by counter switch, external by display screen
Display, above-mentioned information is stored in memory by enumerator, and memorizer will be stored in information therein again and sends
Give outside host computer, it is simple to management personnel carry out concentration information for service condition and the use information of electric furnace
Change management.
Beneficial effect:
(1) switch of the present invention can be permissible by the unlatching of the functional realiey protective cover of fingerprint recognition
Realize the information system management to furnace operation.On the one hand, operator's use to universal electric furnace can be recorded
Time and access times, facilitate the verification of subsequent experimental data and the lookup of person liable;On the other hand, only
Fingerprint people in fingerprint base could pass through fingerprint recognition, opens protective cover, has stopped layman couple
The violation operation of instrument.
(2) construction of switch with fingerprint recognition of the present invention is simple, it is easy to accomplish, extend to thing
Networking arenas, it is achieved the information system management to conventional instrument.

Detailed description of the invention
Develop simultaneously embodiment below in conjunction with the accompanying drawings, describes the present invention.
The invention provides a kind of information-based universal electric furnace with counting and fingerprint identification function, its structure is shown
Be intended to as depicted in figs. 1 and 2, including universal electric furnace 1, protective cover 3, Fingerprint Identification Unit 4, control unit,
Key seat 6, retaining mechanism, torsion spring, rotary switch 2, bearing pin 11, memorizer 13 sum counter 12.
Wherein, the structural representation of described retaining mechanism is as it is shown on figure 3, include micro-step motor 7, leading screw
8 and latch segment 5, the output shaft of described micro-step motor 7 is fixing with leading screw 8 to be connected, latch segment 5 and silk
Thick stick 8 is threaded engagement, and latch segment 5 is slidably matched with the mounting groove on universal electric furnace 1 housing.
Described protective cover 3 is rectangular case structure, outside one end of protective cover 3 is by rotating shaft and universal electric furnace 1
Shell be flexibly connected, described rotating shaft is set with torsion spring, the two ends of torsion spring respectively with protective cover 3 and universal electric furnace 1
Shell is inconsistent, and the rotary switch 2 of universal electric furnace 1 is completely enclosed by protective cover 3 when closure state, protects
Positioning and locking groove on guard shield 3 other end is corresponding with the mounting groove of key seat 6 on universal electric furnace 1 shell, peace
The bottom of tankage is sequentially installed with micro-step motor 7, leading screw 8 and latch segment 5, and micro-step motor 7 exists
Be not powered under state, outside the head of latch segment 5 is positioned at mounting groove and with the positioning and locking groove on protective cover 3
Coordinate and protective cover 3 is locked on universal electric furnace 1 shell;Described micro-step motor 7 passes through control unit
It is connected with the circuit within universal electric furnace 1;Fingerprint Identification Unit 4 is fixedly mounted on the outer wall of universal electric furnace 1,
Fingerprint Identification Unit 4 sends command information to control unit after identifying the identity information of user, controls single
Unit controls the break-make of micro-step motor 7 and universal electric furnace 1 internal circuit.
In the rotating shaft (i.e. rotary switch rotating shaft 10) of described rotary switch 2, the cross section along rotating shaft has with turning
The tortuous groove of Shaft angle change, the fluting direction of tortuous groove is along the circumferencial direction of rotating shaft, the groove bottom of tortuous groove
In the rotation direction of rotating shaft, the outer circumference surface with rotating shaft connects, and the degree of depth of tortuous groove is along the radial variations of rotating shaft;
The width of described tortuous groove is consistent with the diameter of bearing pin 11.
Described rotary switch 2 coordinates with the housing into rotation of universal electric furnace 1, and bearing pin 11 is through universal electric furnace 1 shell
Via on body and the tortuous slot fit in rotary switch rotating shaft 10, bearing pin 11 enters the end of tortuous groove one end
Conflicting with the bottom surface of tortuous groove and coordinate in face, the end face of bearing pin 11 other end supports with the counter switch of enumerator 12
Touch and coordinate (as shown in Figure 4 and Figure 5);Described memorizer 13 is fixedly mounted on outside universal electric furnace 1 housing
Surface, enumerator 12 is connected with memorizer 13, the information real-time storage of enumerator 12 in memorizer 13,
The information of storage is sent to the host computer of outside by memorizer 13 in real time.
Operation principle: finger was placed on Fingerprint Identification Unit 4 before using universal electric furnace 1 by user, referred to
After stricture of vagina evaluator 4 identifies the identity information of user, the instruction starting micro-step motor 7 is sent to
Control unit, control unit controls the rotating forward of micro-step motor 7, when it rotates forward, motor output shaft band
Movable wire thick stick 8 synchronous axial system, owing to mounting groove limits the rotation of latch segment 5, latch segment 5 can only be along installation
Groove inwardly moves linearly, and latch segment 5 exits from positioning and locking groove, when latch segment 5 is completely into mounting groove
After Nei, protective cover 3 loses the restriction of latch segment 5, after protective cover 3 is upspring under the effect of torsion spring automatically
Opening, universal electric furnace just can be operated by user;When rotary knob switchs 2, rotary switch 2
Rotating shaft gradually promotes bearing pin 11 to be gradually backed out tortuous groove, and along with the rotation of rotating shaft, bearing pin 11 does directly along via
Line moves and touches the counter switch on enumerator 12 in the stroke set, and counter switch is recorded this and opened
The operation information closed and operating time, externally being shown by display screen, above-mentioned information is stored by enumerator 12
In memorizer 13, memorizer 13 will be stored in information therein again and is sent to the host computer of outside, it is simple to
Management personnel carry out concentrating information system management for service condition and the use information of electric furnace.After using,
By rotary switch 2 cycle closed position, user can press the reversal switch on micro-step motor 7, control
Unit processed controls micro-step motor 7 and inverts, and latch segment 5 outwards moves linearly along mounting groove, enters protection
It is locked in the positioning and locking groove of cover 3.
In sum, these are only presently preferred embodiments of the present invention, be not intended to limit the guarantor of the present invention
Protect scope.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made,
Should be included within the scope of the present invention.
