Background technology

Along with the China market sustainable development of economy, all trades and professions propose higher requirement to all products, instrument etc.: practical and convenient, safety, and outward appearance is more beautiful, and technology is exquisiteness etc. more.

Summary of the invention

The utility model will solve the shortcoming of above-mentioned prior art, and a kind of triangular key is provided, and this key can be practical in every profession and trade, goes up, cashier's office in a shop uses as doors such as train, aircraft, elevator, subway, file cabinets.

The utility model solves the technical scheme that its technical problem adopts: this triangular key, mainly comprise handle, key bar and key bit, described key bit is tube-in-tube structure, and the one end is connected with key bar, other end heart opening forms open keyhole, and the cross section of open keyhole is triangular in shape.

The cross section of described handle is wing shape structure, and key bar is a cylindrical bar.

The effect that the utility model is useful is: 1, exquisite appearance, and smooth.2, safe and convenient to use.3, the life-span long, thereby save use cost greatly.4, skilful second mechanically stressed principle of this key utilization, firmly evenly; 5, the handle place utilizes skilful second lever stress principle, makes the operator reach the purpose of unblanking in a short period of time.

Description of drawings

Fig. 1 is the utility model master TV structure schematic diagram;

Fig. 2 is the right TV structure schematic diagram of the utility model;

Fig. 3 is that the utility model is looked up structural representation.

Description of reference numerals: handle 1, key bar 2, key bit 3, open keyhole 3-1.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As shown in the figure, this triangular key mainly comprises handle 1, key bar 2 and key bit 3, and described key bit 3 is tube-in-tube structure, and the one end is connected with key bar 2, and other end heart opening forms open keyhole 3-1, and the cross section of open keyhole 3-1 is triangular in shape.The cross section of described handle 1 is wing shape structure, as wing duplicate key handle, can reach laborsaving when unblanking, and is light and handy; Because the handle of wing type make power when unblanking concentrate on key below, strengthened the strength of key like this, easily open door lock.Key bar 2 is a cylindrical bar, and holding in the above can be very comfortable, and its length, width are very moderate.Be positioned at the triangle sky of key bottom, can well pin lock core, block and then open lock very easily, do not have the sensation of slip.

The operating principle of key: utilize mechanics principle to operate, the skilful power that should choose during use is come rotational lock core, reaches the effect of light unlatching door lock, require the spy that handle is carried out the test of dynamics in order to reach this, its shape, length, width all has special requirement; Comfortable feel, dynamics is average, reduces designing from aspects such as gravity when unblanking.Skilful second mechanically stressed principle of this key utilization, firmly evenly.The handle place utilizes skilful second lever stress principle, makes the operator reach the purpose of unblanking in a short period of time.Original and different in the design of key, comfortable feel in use.The kirsite that key of the present utility model is at first used on the selection of material has plasticity and toughness, abrasion resistance, dimensional stability, high-temperature behavior, mechanical property advantages of higher.

In addition to the implementation, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
