Abstract

The utility model relates to a safety door knob, which is mainly composed of a casing composed of a main casing and an outer cover plate, wherein, the front part of the main casing is provided with a structural part which is provided with a folding hook edge and an extending clamp sheet; the outer side of the side plate of the main casing is hung with a folding buckle sheet; the front part of the outer cover plate is provided with a fixed part which is provided with a buckle groove, a clamp groove and a hook groove corresponding to the folding buckle sheet, the extending clamp sheet and the folding hook edge; after the folding buckle sheet and the buckle groove are buckled and combined, the extending clamp sheet and the clamp groove are buckled and combined, the folding hook edge and the hook groove are buckled and combined, the extending clamp sheet is resisted in the clamp groove by a pivot strung into the fixed part, and thus the combination of the main casing and the cover plate is not easy to be pried off or disassembled due to the action of external force; thus the utility model has the functions and effects of safety and anti-theft.

Description

Safety door handle

The utility model provides a kind of relevant for Safety door handle, especially refer to a kind of pivot member that is fixed on doorframe or wall body in order to sectional door panels, the housing of this member has splendid syntagmatic, can prevent effectively that external force from prying open or destroying decomposition, the effect of tool safe antitheft.

Seeing also Fig. 4, is the simple structure schematic diagram of door knob commonly used.As shown in the figure, this door knob mainly is to be fixed on body of wall or the doorframe, use for the door-plate combination, and be member for a pivot.This door knob comprises that one constitutes with the main casing 5 of axle bed 51 one and an outer cover plate 3, wherein these main casing 5 usefulness are for the member setting of involution member or restriction, think effect for antitheft or the automatic involution of door-plate, and be provided with chute 52 at the upper and lower end face of the housing of this main casing 5, slip into and make up for  shape outer cover plate 53 side direction with upper and lower embedding limit 54, and to establish wherein involution member or limiting member are latent.Though the main casing 5 of this door knob has the chimeric effect of forward with the combination of outer cover plate 53, but not having fully for horizontal location has, need be dependent on other sealed accessories fully reaches, yet sealed accessory is disassembled removal easily, it is the common fault of most of latch fittings or door knob, and above-mentioned traditional door knob is disassembled as if its sealed accessory, then main casing 5 and 53 of outer cover plates combine then for anyone execute slightly-strength can side direction take off outer cover plate 53, although how good inner set antitheft or involution member is, all can't avoid the destruction after outer cover plate 53 is removed.

Main purpose of the present utility model is main casing and outer cover plate are provided with group portion and fixed part, and 3 embedding set constructors that set up separately, and the clinching of resistancing action, makes to pin down mutually after combination and the latent setting-in structure of establishing.

In addition, be the simple structure, careful of setting-in, providing assembling easily, otherwise dismounting is difficult for and can protect the involution or the limiting member of inside not to be damaged, and then reaches the effect and the effect of safe antitheft.

The purpose of this utility model is achieved in that the utility model mainly is made up of main casing and outer cover plate etc.Wherein main casing be by side plate, go up, base plate and side plate constituted; The front portion of this outer cover plate is provided with the fixed part of one, and last, the bottom surface of this fixed part respectively are provided with a buttonhole.Wherein the outer marginal lappet of the side plate of this main casing is provided with the eighty percent discount cramp, and is provided with a structural portion in the front portion of this main casing, and the body of this structural portion is the recessed embedding mouth of an arc, stretches card in the side formation one of this embedding mouth, and side then forms a folding by a groove and colludes edge in addition.The end of this outer cover plate also is provided with and the corresponding catching groove of aforementioned discount sheet, and at this outer cover plate the medial surface of fixed part is arranged, and what be provided with and can collude edge for the folding of aforementioned structure portion, stretch the card sets setting-in colludes groove and draw-in groove.

To detailed structure of the present utility model, be described further as follows below in conjunction with accompanying drawing:

Fig. 1 is an organigram of the present utility model;

Look with A-A generalized section on Fig. 2 Fig. 1;

Fig. 3 is the combination schematic diagram of Fig. 2;

Fig. 4 is the simple structure schematic diagram of existing door knob.

Seeing also Fig. 1, is structural representation of the present utility model, mainly is to be the composite construction of a main casing 1 with outer cover plate 3.This main casing 1 be by on the side plate 14,,

base plate

11,12 and a side plate 13 constituted: and the front portion of this outer cover plate 3 is provided with the fixed part 32 of one, and the going up of this fixed part 32, bottom surface respectively are provided with a buttonhole 33.Wherein, the side plate 13 outer marginal lappets of this main casing 1 are provided with eighty percent discount cramp 15, and be provided with a structural portion 2 in the front portion of this main casing 1, the body of this structural portion 2 is the recessed embedding mouth 21 of an arc, then form a side in a side of this embedding mouth 21 and then form one and stretch card 22, in addition side then mat one groove 24 collude edge 23 to form a folding.And the end of this outer cover plate 3 also is provided with and aforementioned discount sheet 15 corresponding catching grooves 31, and, be provided with and collude edge 23 for the folding of aforementioned structure portion 2, stretch that card 22 colludes the group setting-in colludes groove 35 and draw-in groove 34 (as shown in Figure 2) at the medial surface of the fixed part 32 of this outer cover plate 3.

See also Fig. 3, it is combination schematic diagram for Fig. 2, as shown in the figure: the structural portion 2 of this main casing 1 and front end thereof, be provided with discount sheet 15, stretch card 22 and roll over three button hook parts such as colluding edge 23, the relative inner face of this outer cover plate 3 and fixed part 32 thereof is provided with catching groove 31, draw-in groove 34 and colludes catching groove such as groove 35 partly.On button group relation and sequencing, be that discount sheet 15 buttons are organized in catching groove 31, again this is stretched card 22 and folding colludes edge 23 with an arc angle, pressure is organized in relative draw-in groove 34 and is colluded in the groove 35.In fact, aforementioned only is the effect of a combination, is unlikely to come off.So must mat the door knob pivot seal in buttonhole 33, pivot resists and stretches card 22 in addition, can make these two groups of bodies in conjunction with and not the effect of reason external force pry open or separate.

And by aforesaid structure, will organize more the door knob device on doorframe and group establish door-plate, no matter why are the inside involution of this door knob or restriction structure, all can't make main casing 1 and outer cover plate 3 decompose or break away from easily, thereby have antitheft effect.

Brought forward is described, and the utility model has more improvement than existing this apparatus, has reached inventor's goal of the invention.
