Abstract
The utility model discloses an outer door switch of double-layer mailbox, comprising a sheet steel (3) fixed on the door frame (1) of the housing and a base (8) fixed on the door panel (12); wherein a magnetic steel seat mounting hole (9), a spring mounting hole (11), and a guide hole for communicating the magnetic steel seat mounting hole (9) and the spring mounting hole (11) are coaxially arranged on the base (8). A magnetic steel seat (6) is arranged in the magnetic steel seat mounting hole (9), and a magnetic steel (4) is fixed on the magnetic steel seat (6). The magnetic steel (4) is corresponding to the sheet steel (3) arranged on the door frame (1) of the housing; a spring (7) is arranged in the spring mounting hole (11); a screw (5) is fixedly connected with the magnetic steel (6) after going through the spring (7) and the guide hole (10). Using the structure, the unreliable closing problem caused by spring piece abrasion and elasticity natural decrescence is solved. The utility model has the advantages of rational and simple structure, convenient use and installation, wide application range, and stable and reliable operation.
Description
Technical field
The utility model relates to a kind of positioner, particularly a kind of fixing door switch of outer chamber door that is used for double-deck mailbox.
Background technology
The outer chamber door of existing double-deck mailbox generally is to fix one 7 type spring leafs on door-plate, the position of spring leaf is a little more than the inner edge of casing doorframe, when at closing time, casing doorframe inner edge forces the position that overhangs of spring leaf to be out of shape downwards, after door is shut, since the elastic reaction of spring leaf, the oriented tension force of going up of its part that overhangs, thus keep door-plate to be in closing state; This structure has the following disadvantages: the one, because spring leaf directly contacts with doorframe, can destroy the outward appearance of doorframe; The 2nd, cause the wearing and tearing of casing doorframe, after the doorframe wearing and tearing, the tension force of spring leaf just can't be kept door-plate and be in closing state; The 3rd, elasticity can go down by nature after spring leaf used a period of time, caused door-plate intactly to close.For this reason, many scientific research institutions, manufacturer and knowledgeable people have constantly carried out R and D at the problems referred to above that exist, and do not improve way preferably but have as yet so far.
Summary of the invention
Be to overcome the above-mentioned disadvantage that the outer door switch of existing double-deck mailbox exists, the purpose of this utility model just provides a kind of outer door switch of simple and reasonable, easy to install, the double-deck mailbox of stable and reliable operation.
The technical scheme that its technical problem that solves the utility model adopts, it comprises the steel disc that is fixed on the casing doorframe, is fixed on the pedestal on the door-plate, described pedestal is provided with the coaxial guide hole that magnet steel seat installing hole and spring mounting hole and connection magnet steel seat installing hole and spring mounting hole are set, in the magnet steel seat installing hole magnet steel seat is housed, be fixed with magnet steel on the magnet steel seat, magnet steel is corresponding with the steel disc on the casing doorframe, be provided with spring in the spring mounting hole, screw is fixedlyed connected with magnet steel seat after passing spring and guide hole.
After adopting said structure, when door closed, magnet steel was inhaled with steel disc at the magnetic action lower magnetic steel mutually over against steel disc, and magnet steel drives magnet steel seat simultaneously and screw moves, and compressed spring by screw, guaranteed that by magnetic attraction door-plate reliably cuts out; After door was opened, magnet steel broke away from steel disc, was compressed spring promotion screw, magnet steel seat and magnet steel and resetted; Have advantages such as simple and reasonable, easy to install, applied widely, that working stability is reliable.The utility model also is applicable to office or household implements such as cabinet, desk.
