Abstract
The utility model relates to a fire door lock locking in three directions, comprising a driven rod, a bottom buckle and a top buckle. A clamping lock block is in the casing of the main lock body. The spring plunge is connected with the casing after penetrating the clamping lock block. A fulcrum rod penetrates the perforation of the upper press plate arranged in the casing and is connected with the casing. One end of the upper press plate is provided with a shifting end which is clamped in the clamping lock block. The top end of the lower press plate fixed to the upper press plate is provided with contact rollers. The casing is provided with a set of opposite long holes. The side edges of the contiguous long holes are respectively provided with openings. Driven strips are arranged in the openings. One of the two L-shaped interlink plates is provided with a plug-in sheet inserted in the opposite long hole. The front end of the lower interlink sheet is positioned on the lower part of the transversal sheet of the driven strip. The wing sheets on the both sides of the upper press plate are respectively corresponding to the end face on one side of the interlink sheet. The length of each long hold is a little longer than the length of the plug-in sheet so as to enable each plug-in sheet to rotate in the long hole. The utility model has the advantages of small volume, simple structure, and convenient production and manufacture and frame assembling and construction.
Description
Technical field
The utility model relates to a kind of fireproofing door lock, particularly a kind of simple in structure, volume is little, produce fast, and can reach the assembling construction Three-bearing fireproofing door lock of locking quite easily.
Background technology
High buildings and large mansions are when breaking out of fire, flame and smog can prolong the space of interior of building and scurry burning, can cause the survivor can not escape with having or cause death by suffocation because of sucking too much dense smoke, so Emergency Ladder is the important passway for escaping of interior of building, but fire prevention escape insufficient strength as each floor, easy deformation, then can lose due barriers function, and can reduce the scene of a fire victim probability of surviving, so good escape need to allow the survivor be easy to open under emergency, and can when closing, be subjected to high heat also indeformable, and can effectively isolate flame and dense smoke, stretch to stop the intensity of a fire, and can guarantee the escape of building internal staff's safety.
" fireproofing door lock structural improvement ", mainly be for having the dual fireproofing door lock of locking effectiveness admittedly, this door lock partly is divided into main lock body, top button and end button, following setting is buckled the end of with this top and is buckled the buckling device that cooperates on doorframe, form two-bolt lock, 3 blockade points come the reinforced door body structure, fireproofing door lock has typing and limit function, can avoid a body to produce Texturized because of the high hot temperature in the scene of a fire, isolate burning things which may cause a fire disaster spring and smog to strengthen, but, when above-mentioned traditional type is configured in actual use, but has following shortcoming: in the unlatching of control fireproofing door lock or when closing, must be by two microscler movement arms, each movement arm is stretched out towards the outside by the housing place of main lock body respectively, wherein a movement arm penetrates driven the cross bar below that inside is set, the mat movement arm produces relative action, unlatching or reason with the control fireproofing door lock are closed, but its shortcoming is: structure is comparatively complicated, and produces slower, when the assembling construction, must two movement arms are overhanging by the housing place of main lock body, just can be arranged in driven inside, and be positioned at the cross bar bottom, event has the shortcoming that volume is big with it is all quite inconvenient that assembling is constructed, and necessity of being improved is arranged in fact.
Summary of the invention
The purpose of this utility model is the structure existing problem in reality is used that solves fireproofing door lock of the prior art, provides that a kind of to have a volume little, simple in structure, produces fast, and can reach assembling construction fireproofing door lock quite easily.The utility model designs the fireproofing door lock that a kind of Three-bearing is locked, comprise main lock body, follower lever, end button and top button composition, follower lever comprises one driven, a transverse sheet is established in inside, upper and lower place by driven establishes a connecting rod respectively, and the top of the below of bottom connecting rod and top connecting rod is respectively equipped with end button and top button; Main lock body, comprise housing, one clip lock dog is located in the housing, is connected in housing after having a spring hitch to wear the clip lock dog, and the upper and lower part that enclosure interior is positioned at spring hitch is provided with a spring respectively, one vertically wears the fulcrum bar of housing, wear perforation place of being located at the last compressing tablet of enclosure interior, last compressing tablet one end is provided with the struck side, and this struck side presses in the clip lock dog, one lower sheeting that sets firmly with last compressing tablet, lower sheeting end are in addition established a roller; It is characterized in that: the upper and lower position of housing is respectively equipped with one group of relative slotted hole, and the side upper and lower position of housing place and adjacent each slotted hole has a corresponding opening respectively, and this corresponding opening can supply driven setting; One L-shaped double-action plate is arranged respectively, have an inserted sheet to be inserted in the relative slotted hole on it respectively; The set double-action plate front end in below is to be positioned at driven the transverse sheet bottom that inside is set; Be respectively equipped with a fin in the upper and lower position of last compressing tablet, each fin corresponds respectively to double-action plate one side end face.Wherein the length of each slotted hole is slightly larger than the length of inserted sheet, so that each inserted sheet is in each slotted hole inner rotation.It is little, simple in structure to the utlity model has volume, and it is convenient to manufacture, and assembles the advantage quite easily of also constructing.
