Description
Technical field
This utility model relates to a kind of building material field, is specifically related to a kind of High-flame-retardancfireproof fireproof door catch device.
Background technology
Fire resistance steel door is make doorframe and door-plate of steel material, and is equipped with the door with certain fire resistance that fire prevention Hardware fitting forms.Current fire resistance steel door is when breaking out of fire, and door-plate can deform after being burnt certain time (because flame upwards alters, so deformation position is typically on door-plate edge), and flame, dense smoke will alter crack between a door and its frame, it is difficult to intercept spreading of fire.Chinese patent Authorization Notice No. CN204060419U discloses one " fire resistance steel door ": the door-plate that include doorframe, is hinged on doorframe by hinge, for preventing on door-plate the detent configuration along deformation, detent configuration includes being arranged on door-plate back of the body fire face and the fixed cover on edge is slidably connected with fixed cover on door-plate lock pin and is arranged on doorframe and the plunger set corresponding with fixed cover position, fixed cover open top, bottom lock, lockpin ventilating is crossed fuse link and is connected with bottom fixed cover, is provided with the spring being in compressive state between bottom lock pin and fixed cover.This fire resistance steel door is when breaking out of fire, and door-plate will not deform, and can effectively prevent flame and dense smoke from altering crack between a door and its frame, but there is lower column defects: fixed cover bottom lock, change the fuse link being positioned at bottom fixed cover relatively time-consuming bothersome.
Summary of the invention
This utility model is for the deficiencies in the prior art, it is proposed to a kind of fuse link changes High-flame-retardancfireproof fireproof door catch device fast and easily.
This utility model is achieved through the following technical solutions technical goal.
High-flame-retardancfireproof fireproof door catch device, is arranged on doorframe between edge, door leaf；Including sleeve, fixed cover, latch, compression spring, fuse link；Described sleeve, fixed cover are coaxially oppositely arranged, and are respectively fixedly connected with on doorframe on edge, door leaf back of the body fire panel；Described latch is arranged in fixed cover, and with fixed cover endoporus matched in clearance, latch end can be inserted in sleeve；It thes improvement is that: described High-flame-retardancfireproof fireproof door catch device also includes end cap；Described end cap is fixedly connected on one end of fixed cover sleeve dorsad；Fuse link, compression spring it is provided with between described latch, end cap；Described fuse link two ends are fixed with latch, end cap respectively and are connected；Described compression spring housing is contained on fuse link.
In said structure, it is provided with fire prevention in described sleeve and expands cushion rubber；Described fire prevention expands cushion rubber and is fixedly connected in sleeve；Described latch is provided with ladder axle head towards sleeve one end, and described ladder axle head can be inserted into fire prevention and expands in cushion rubber endoporus.
In said structure, described compression spring is arranged on centre between latch, end cap.
This utility model compared with prior art, has the positive effect that:
1. it is provided with end cap in one end of fixed cover sleeve dorsad, as fuse link need to be changed, it is only necessary to pull down end cap, convenient and swift.
2. it is provided with fire prevention in sleeve and expands cushion rubber, latch is provided with ladder axle head towards sleeve one end, and ladder axle head can be inserted into fire prevention and expands in cushion rubber endoporus, so, sleeve can be carried out axial limiting on the one hand, on the other hand, during breaking out of fire, fuse link fuses, latch ladder axle head inserts fire prevention in sleeve and expands in cushion rubber, fire prevention expands cushion rubber and expands gradually, stuck fast latch ladder axle head, it is to avoid during spring force deficiency, latch ladder axle head skids off in sleeve.
3. compression spring is arranged on centre between latch, end cap, and the spring force ratio suffered by latch can be made more uniform.
