Abstract

The utility model relates to a two-stage hook which takes a hook head as the main body; the main body is integrally connected with a hook area through a connecting rod part. The two-stage hook is characterized in that an auxiliary hook head is connected to the upper side of the hook head through a connecting rod, a beveling is arranged at the junction of the hook head and the auxiliary hook head and has the radian ranging from 70 to 90 degrees, the connecting rod part between the hook head and the auxiliary hook head serves as a relieving area that has the length ranging from 8 to 12 mm, the hook area is U-shaped, and a wedged stopper is arranged at the upper part of the left end of the hook area. In the utility model, the auxiliary hook head is additionally arranged at the hook head, so that double safety of the hook in use is ensured, and when the two-stage hook is used in a corresponding double-layered slide track, the elegance of the hook is increased while the firmness is increased; and even if the hook is used in a common single-layered slide track, the function of preventing the hook from disengaging the track due to a powerful external force can be achieved through the design of the relieving area.

Description

The twin-stage hook

Technical field:

The utility model relates to a kind of medical tieback, but relates in particular to a kind of twin-stage hook of safety in utilization of duplicate protection hook.

Background technology:

Hook belongs to the connector of fishhook shape, and in the existing market, the kind that is applied in the various hooks of medical medical curtain aspect gets more and more, and fancy is also various, but because the effect of self using is smaller, its fastness is often ignored by the people; Hook is a kind of by self connection, hanger or ornaments is connected and fixed, and hangs skyborne device.General hook all adopts metal material to make in order to increase tightness, simplicity of design, being made up of hook district and hook head portions sheerly.Like this, for simple medical tieback, people only consider and adopt the one-level hook head portions to be connected with slide rail, but because long-term slidably reciprocating, hook head portions causes wearing and tearing easily, and do the time spent for strong external force, hook head portions more can not be born its pulling force and be produced fracture, causes certain loss easily.

Summary of the invention:

Technical problem to be solved in the utility model provides a kind of simplicity of design, service-strong twin-stage hook.

The technical scheme in the invention for solving the technical problem is: a kind of twin-stage hook, main body is a hook head portions, be connected with hook head portions is whole, be connected with the hook district by link rod part, the upside of described hook head portions is connected with auxiliary hook head portions by connecting rod.

In order to guarantee that it increases being connected firmly of auxiliary hook head portions and integral hook, the junction of described hook head portions and auxiliary hook head portions is provided with chamfering, and the radian of its chamfering is 70 °～90 °.

In order to guarantee that integral hook does the time spent in strong external force, hook head portions fracture and do not influence the serviceability of integral hook, described hook head portions is the slow district that connects with shaft portion in the middle of the auxiliary hook head portions, it delays the length range that meets the district is 8mm～12mm.

Hung thing in order to fasten, described hook district becomes " U " type, and is provided with wedge-shaped catch on left end top, hook district.

After adopting said structure, be characterized in: this kind hook is equipped with auxiliary hook head portions on hook head portions, guarantees hook double safety in use, and uses and also increased its fineness when having increased the hook fastness in the double-deck slide rail of correspondence; Even use in common individual layer slide rail, the slow design that meets the district can guarantee that also hook by powerful external force on, plays and avoids linking up with the effect that de-orbits.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a schematic diagram of the present utility model;

Fig. 2 is the schematic diagram of the utility model in concrete slide rail.

Among the figure: 1, hook head portions 1-1, slow district 1-2, chamfering 2, auxiliary hook head portions 3, connecting portion 4, hook district 4-1, wedge-shaped catch 5, the slide rail of connecing

The specific embodiment:

A kind of twin-stage hook shown in Figure 1, main body is a hook head portions 1, with 1 whole connection of hook head portions, is connected with hook district 4 by link rod part 3, the upside of described hook head portions 1 is connected with auxiliary hook head portions 2 by connecting rod; Hook head portions 1 is provided with chamfering 1-2 with the junction of auxiliary hook head portions 2, and the radian of its chamfering 1-2 is 70 °～90 °, and the auxiliary hook head portions 2 that adds after the assurance is connected firmly with original hook head portions 1; Hook head portions 1 is distinguished 1-1 with the shaft portion in the middle of the auxiliary hook head portions 2 for slow connecing, its slow length range that meets district 1-1 is 8mm～12mm, guarantee that integral hook is when original hook head portions is subjected to the external force effect to break away from slide rail 5 suddenly, can play the effect of buffering, guarantee can not rupture when slide rail 5 contacts with auxiliary hook head portions 2 because of the adaptability to changes that produces suddenly, hook is distinguished 4 one-tenth " U " types, and is provided with wedge-shaped catch 4-1 on 4 left end tops, hook district, has guaranteed to be hung the steadiness of thing.

1 is equipped with auxiliary hook head portions 2 on the hook head portions shown in Figure 2, guarantees hook double safety in use, and uses and also increased its fineness when having increased the hook fastness in the double-deck slide rail 5 of correspondence; Even use in common individual layer slide rail 5, the slow design that meets district 1-1 can guarantee that also hook by powerful external force on, plays and avoids linking up with the effect that de-orbits.
