The specific embodiment
Accompanying drawing has been represented the utility model structure, below in conjunction with accompanying drawing embodiment is described in further detail: comprise that body (1) is provided with working chamber, the spring that slip working beam (16) is installed in this working chamber and is mated, it is hinged that slip working beam (16) passes through a termination and the connecting rod (2) of working chamber wall, connecting rod (2) is hinged with operation block (3), operation block (3) is by axle, bearing is arranged on the body, be positioned to be set with on this external and swing arm (4) that operation block (3) is fixedlyed connected and close a connecting rod (5), described slip working beam (16) is set with sliding shoe (6), the hinged push rod in the edge of sliding shoe (6) (10), slotted hole slip fit on this push rod (10) and the work package (7), work package (7) is positioned at outside the working chamber, work package (7) is by axle, bearing is arranged on the working chamber wall, work package (7) connects regulating spring (8) one ends, another termination of regulating spring (8) is fixedly installed on the termination of screw (11), this screw (11) is spirally connected with flange (12), flange (12) is fixedly installed on the body (1), adjustment screw (11) can be controlled spring (8) degree of tightness, thereby handles the speed of closing door.For the mobile stationarity of sliding shoe (6), sliding shoe (6) is provided with pilot hole, guide peg (9) is installed in this pilot hole, guide peg (9) is parallel with slip working beam (16), its two ends are fixedly installed on the both sides of working chamber wall respectively, the fixed axis of work package (7) overlaps by work in the installing hole that is installed on the stiffener (17), and stiffener (17) increases the stationarity of working shaft.Another kind of embodiment, work package (7) can be gear, the edge of sliding shoe (6) be provided with tooth bar or with the perforation of gear interlock, reach the purpose of action equally.
The cross section, termination of the fixed axis of described operation block (3) is semicircle, this termination cooperates with a contact chip (13), this contact chip (13) is arranged on the metallic conduction sheet (14), this metallic conduction sheet (14) is arranged on the body (1) by insulating trip, screw, described body is a metal material, connect a lead, metallic conduction sheet (14) connects another lead, and this two lead connects switch and alarm.Described contact chip (13) configuration flexible member (15) avoids contact chip (13) over a long time owing to mechanical presses work is out of shape, and causes warning malfunctioning.When switch closure, after the door closure, the termination of the fixed axis of operation block (3) and contact chip (13) are in off-state, in a single day door is opened, and axle contacts conducting with contact chip, and alarm sends alarm sound, thereby plays the warning effect.
