Embodiment Construction
[0016] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0017] The invention provides a translational opening type universal electric furnace switch with fingerprint identification function, its structural schematic diagram is as follows figure 1 As shown, the switch includes a protective cover 2 , a cover 4 , a fingerprint reader 3 , a control unit, an electromagnet 6 , a locking pin 5 and a return spring 7 .
[0018] Wherein, the protective cover is a rectangular shell structure, the upper and lower bottom surfaces of which are open structures, and one open end of the protective cover is fixedly connected to the position of the electric furnace switch on the shell of the universal electric furnace 1, and one end of the protective cover Symmetrical chute 8 is processed on the two opposite side walls of the chute, and the chute 8 is slidably matched with the cover 4. When the cover 4 slides from the entrance en...

The invention discloses a horizontal-movement opening type wire coil heater switch with a fingerprint recognition function. The horizontal-movement opening type wire coil heater comprises a protection cover, a seal cover, a fingerprint recognizer, a control unit, electromagnets, locking pins and resetting springs. The upper bottom surface and the lower bottom surface of the protection cover are of open type structures, one open end is fixedly connected to the position, corresponding to the wire coil heater switch, of a shell of a wire coil heater, symmetrical sliding grooves are machined in the two opposite side walls of one end and matched with the seal cover in a sliding mode, and when the seal cover slides to the tail ends from the inlet ends of the sliding grooves, the other open end of the protection cover is completely sealed. Pin holes are machined in the side walls of the tail ends of the sliding grooves, the electromagnets, the resetting springs and the locking pins are sequentially installed at the bottoms of the pin holes, and the electromagnets are connected with a circuit inside the wire coil heater through the control unit. The fingerprint recognition device is fixedly installed on the outer wall of the wire coil heater and recognizes identity information of a user, then the seal cover is free from the limit of the locking pins, and the user horizontally moves the seal cover and then can operate the wire coil heater.
Description
technical field [0001] The invention relates to a switch for a universal electric furnace, in particular to a translation-opening universal electric furnace switch with a fingerprint identification function, which belongs to the technical field of mechanical structures. Background technique [0002] At present, large-scale construction quality inspection companies need to use various types of test instruments to sample, analyze and inspect buildings when conducting inspection tests, such as using a universal electric furnace to heat and sample samples for analysis. [0003] The operator needs to fill in the operation record after each test operation, which includes the opening time of the instrument and the number of times of use. Due to the level and sense of responsibility of the operator, there are often cases of forgetting or omissions, which makes the test There are hidden dangers in data and equipment management, which is not conducive to the realization of scientific ...
