Abstract
The utility model discloses an interlock and system of latching for machine cover, include: the latch means is including machinery couple and door latch, electric contact 1 matches and passes through the route through couple and door latch mechanical bond and accomplish the circuit with electric contact 2, a hall effect sensor and a magnet, thus, when the machine cover is closed and is latched, the electric contact is closed by machinery, magnet triggers hall effect sensor and sends a signal for the machine control ware through the circuit, the machine control ware prohibits that machine operation is received up to the signal, hall effect sensor and latch means have combined to form one kind hardly by the dual interlocking of deception or manipulation like this, the utility model discloses the problem and the beneficial effect that solve are: use dual interlock system structural design, prevent that interlocking and the system of latching are difficult by the deception or handled, it is also integrated to the present system in very easily, more guarantee operator's health safety.
Description
Technical field
This utility model relates to the latch means of a kind of electrophotographic printer, and being specifically related to can a kind of interlocking for machine cover of integral installation and latched system.
Background technology
It is known that, use various technology to try one's best in printing industry and reduce the potential safety hazard that operator touches, such as mobile parts, electric charge or chemical substance etc. during machine operation, in this respect, when using safety interlock switch to suppress machine operation, door or lid are opened, currently used is piston-type switch, one of them contact is changed by the motion of the corresponding door of piston movement or lid, but easy interlocking switch can be spoofed or be manipulated by present, spurious signal is caused to carry out analog gate or lid is to close as inserted a foreign body between contacts, and fact door or lid are opened, so operator is brought great potential safety hazard.
Summary of the invention
The technical problems to be solved in the utility model is to use dual interlock system structure design, it is prevented that interlocking and latched system are not easily spoofed or are manipulated by, and are also easily integrated in existing system, more guarantee the physical safety of operator.
In order to solve above-mentioned technical problem, this utility model employing technical scheme is: a kind of interlocking for machine cover and latched system.
A kind of interlocking for machine cover and latched system, including: latch means includes mechanical hook and bolt, electric contact 1 mates with electric contact 2 and completes circuit by hook and bolt mechanical bond by path, machine operation power on circuitry, interlock is provided with a hall effect sensor and one block of Magnet, so, when machine cover is closed and latches, electric contact is by mechanical closing, Magnet trigger sensor sends a signal to machine controller by circuit, machine controller forbids machine operation until signal is received, such sensor and latch means combine and define a kind of dual interlock being difficult to and being spoofed or handle.
Described hall effect sensor is positioned at a position of latch means, is installed in adjacent with latch means.
Described Magnet is installed on machine cover, and by the mechanical bond of latch means, it is brought to close to hall effect sensor.
Advantage to be solved in the utility model and providing the benefit that: use dual interlock system structure design, it is prevented that interlocking and latched system are not easily spoofed or are manipulated by, and are also easily integrated in existing system, more guarantee the physical safety of operator.
Accompanying drawing explanation
Accompanying drawing 1: a kind of interlocking for machine cover and latched system schematic diagram.
Detailed description of the invention
nullBelow in conjunction with accompanying drawing, this utility model is described further: a kind of interlocking for machine cover and latched system，Including: latch means includes mechanical hook (1) and bolt (2)，Electric contact 1(3) with electric contact 2(4) mate and pass through path (5) complete circuit by linking up with (1) and bolt (2) mechanical bond，Machine operation circuit (6) is energized，Interlock is provided with a hall effect sensor (7) and one piece of Magnet (8)，Hall effect sensor (7) is positioned at a position of latch means，It is installed in adjacent with latch means，Magnet (8) is installed on machine cover，By the mechanical bond of latch means, it is brought to close to hall effect sensor (7)，So，When machine cover is closed and latches，Electric contact (3，4) by mechanical closing，Magnet (8) triggers hall effect sensor (7) and sends a signal to machine controller (10) by circuit (9)，Machine controller (10) forbids machine operation until signal is received，Such hall effect sensor (7) and latch means combine and define a kind of dual interlock being difficult to and being spoofed or handle.
Claims (3)
1. the interlocking for machine cover and latched system, including: latch means includes mechanical hook (1) and bolt (2), electric contact 1(3) with electric contact 2(4) mate and pass through path (5) complete circuit by linking up with (1) and bolt (2) mechanical bond, machine operation circuit (6) is energized, interlock is provided with a hall effect sensor (7) and one piece of Magnet (8), so, when machine cover is closed and latches, electric contact (3, 4) by mechanical closing, Magnet (8) triggers hall effect sensor (7) and sends a signal to machine controller (10) by circuit (9), machine controller (10) forbids machine operation until signal is received, such hall effect sensor (7) and latch means combine and define a kind of dual interlock being difficult to and being spoofed or handle.
2. the interlocking for machine cover according to claim 1 and latched system, it is characterised in that: described hall effect sensor (7) is positioned at a position of latch means, is installed in adjacent with latch means.
3. the interlocking for machine cover according to claim 1 and latched system, it is characterised in that: described Magnet (8) is installed on machine cover, and by the mechanical bond of latch means, it is brought to close to hall effect sensor (7).
