Abstract
A two-piece type multifunctional door knob comprises metal pieces; an inner door knob and an outer door knob are designed at two ends of each metal piece, a mounting hole is designed in the middle portion of each metal piece, a metal chain is fixedly connected with the inner door knob position at one end of each metal piece, and an iron bar is fixedly connected to the metal chain; and the inner door knob and the outer door knob which are designed at two ends of each metal piece are lock holes. Cylinder neodymium-iron-boron strong magnetic materials are fixedly glued on the inner side of each metal piece of the two-piece type multifunctional door knob, and the neodymium-iron-boron strong magnetic materials have neodymium-iron-boron magnetism, so that the door knob has strong magnetism when closed, and a door can be automatically closed. If a two-piece type metal piece or a metal plate is a magnetic stainless steel plate, the neodymium-iron-boron strong magnetic materials can be used or can not be used; one metal piece provided with the metal chain and the lock bar is installed on a door edge, and the other metal piece is installed on a door frame; and the two-piece type multifunctional door knob has the advantages of being simple in structure, economical and practical, free of repair, good in safety performance and the like.
Description
Technical field
The utility model relates to a kind of nose, relates in particular to a kind of two-piece type multi-function door nose.
Background technology
The door nose is widely used among the building safety protection field, and at present, the normal door nose that uses is promptly followed closely copper or iron semi-circular thing on door in our life, can be interpreted as the aperture that can put on other things above the implements again.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, two-piece type multi-function door nose that safety is good.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of two-piece type multi-function door nose comprises: sheet metal; It is characterized in that: respectively be designed with inside door nose and external door nose on the two ends of sheet metal, the mid portion of sheet metal is designed with installing hole, and an end inside door nose place of sheet metal is fixedly connected with metallic bond, is fixedly connected with iron rod on the metallic bond.
According to described a kind of two-piece type multi-function door nose, it is characterized in that: inside door nose that designs on the two ends of said sheet metal and external door nose are lockhole.
The inboard fixing glue of the sheet metal of the utility model two-piece type multi-function door nose has cylindric ndfeb magnetic material; Has neodymium iron boron magnetic; Has powerful magnetic when closed; Can self-closing doors, if double-disk sheet metal or metal sheet are the magnetic corrosion resistant plate, ndfeb magnetic material uses and disuses all can; The sheet metal that has metallic bond and lock rod is installed on the limit, and another sheet is installed on the doorframe; Have simple in structure, economical and practical, need not maintenance, characteristics such as security performance is good.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing: 1, inside door nose; 2, sheet metal; 3, installing hole; 4, external door nose; 5, metallic bond; 6, iron rod.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:
The utility model is as shown in Figure 1, comprising: sheet metal 2; Respectively be designed with inside door nose 1 and external door nose 4 on the two ends of sheet metal 2, the mid portion of sheet metal 2 is designed with installing hole 3, and an end inside door nose 1 place of sheet metal 2 is fixedly connected with metallic bond 5, is fixedly connected with iron rod 6 on the metallic bond 5.
The inside door nose 1 that designs on the two ends of sheet metal 2 is lockhole with external door nose 4.
The design principle of the utility model:
The utility model is to be made up of 2 sheet metals of the inside and outside door nose of two pairs of symmetries or metal sheet; The thread tapping hole that while sheet metal or metal sheet central authorities have 4 symmetries; Be each sheet metal or metal sheet being fixed on Men Bian and the doorframe of symmetry respectively; Door when closing just in time 2 sheet metals or metal sheet closing closely together, the door nose (lockhole) at two ends also lumps together, so that lock or lock rod; Wherein follow closely and on the sheet metal on door limit or metal sheet, have metallic bond and lock rod; 2 sheet metals or the metal sheet of the utility model have neodymium iron boron magnetic, have powerful magnetic when closed, can self-closing doors; Simultaneously inside and outside 2 door noses can freely lock or padlock, near the inner room one side rod of also can locking, have increased antitheft and safety, have saved the latch of inner room simultaneously.
The utility model is realized through following technical scheme and embodiment:
1, double-disk sheet metal or metal sheet
Double-disk sheet metal or metal sheet specification: length * wide * thick=10～15 * 3.5～5 * 0.5～1cm; Material is iron plate or corrosion resistant plate or directly is magnetic corrosion resistant plate (Dongguan Europe superscript alloy product Co., Ltd provides); More than the magnetic intensity 500Gs; Each sheet metal or metal sheet specification must be erased four jiaos and corner angle, and a slice is installed on the doorframe, and a slice correspondence is installed on the limit.
2, door nose
The door nose is positioned at double-disk sheet metal or metal sheet two ends, and each sheet totally 2 inside and outside door noses, promptly the middle of the distolateral 1～1.5cm of distance each beat one of the circular hole of diameter 1-2cm, form a nose; The door nose that each sheet metal or metal sheet are given birth to is symmetry in twos, can be closed into one.
3, installing hole
Mounting hole site has 4 (for quadrangle, the installing hole in each angle) in double-disk sheet metal or metal sheet centre; Be a kind of aperture that thread tapping can be installed, installing hole is arranged length * wide=3～4 * 2.5～4 at double-disk sheet metal or metal sheet centre; Installing hole diameter 0.3-0.6cm; The interior outside of each installing hole is all fluted, is convenient to when thread tapping screws tight, form the plane, and is not outstanding.
4, ndfeb magnetic material
Each sheet of double-disk sheet metal or metal sheet; (Jiangxi Leiyuan Permanent Magnetic Materials Co., Ltd. produces cylindric ndfeb magnetic material on the inboard glue of door nose; More than the magnetic intensity 500Gs) one, cylindric ndfeb magnetic material specification: diameter 1cm, thickness 0.5～1cm; If double-disk sheet metal or metal sheet are the magnetic corrosion resistant plate, ndfeb magnetic material uses and disuses all can.
5, metallic bond and lock rod
Metallic bond one end is positioned at the wherein lower end of a film gate nose (can rivet or weld) of double-disk sheet metal or metal sheet; The other end connects the lock rod; Metallic bond is STAINLESS STEEL CHAINS (production of Ningjin plain sailing network chain factory); Specification: length * wide=5～10 * 0.5～1cm, a slice that has metallic bond and lock rod is installed on the limit, and another sheet is installed on the doorframe.
The lock rod: diameter is slightly smaller than the aperture of a nose, the column stainless steel pole of length 3～5cm.
The beneficial effect of the utility model:
