Abstract

The utility model discloses a tensile spacing couple spring, include that both ends are provided with the spring body of couple, the couple is the integrated into one piece structure with the spring body, is extended to buckle to the outside by the head and the tail both ends of spring body to form, and the vertical lead division of couple lies in the axial lead of spring body, and on the vertical lead division at spring body both ends, equal slidable overlaps and is equipped with the connecting piece, be connected with between the connecting piece at both ends to be used for tensile spacing telescopic link, the utility model provides a tensile spacing couple spring can avoid the situation because of the too big elastic break -down of causing of atress.

Description

The spacing hook spring of a kind of stretching

Technical field

This utility model relates to spring structure design field, spacing particularly to one stretching Hook spring.

Background technology

Hook spring is spring common in a kind of daily life, and two ends can be respectively provided with hook, hangs What hook spring typically utilized is its can the performance of elastic stretching, such as, can be used on hanging object, But, the stretching ability to bear of spring is limited, and object suspension is in its lower end, if it hangs Stress is uncontrollable, when can keep beyond the field of load of elasticity beyond it, spring can be caused permanent Lost efficacy, it is impossible to be further continued for using.

In sum, how to avoid hook spring to cause elastic failure because stress is excessive, become this The technical problem that skilled person is urgently to be resolved hurrily.

Utility model content

The purpose of this utility model is to provide the spacing hook spring of a kind of stretching, it is possible to avoid because being subject to The excessive situation causing elastic failure of power.

For solving above-mentioned technical problem, this utility model provides following technical scheme:

The spacing hook spring of a kind of stretching, is provided with the spring body of hook including two ends, described Hook and described spring body are formed in one structure, by the head and the tail two ends of described spring body to Outside extension bending forms, and the vertical lead division of described hook is positioned at the axle center of described spring body On line, on the vertical lead division at described spring body two ends, the most slidably it is arranged with connector, Connect between the described connector at two ends and have for stretching spacing expansion link.

Preferably, described connector is provided with the installing hole for connecting described expansion link.

Preferably, the two ends of described expansion link are provided with screw thread, by being arranged at described connection The nut of the upper and lower both sides of installing hole of part is fixed on described connector.

Preferably, described expansion link includes overcoat and inner core.

The spacing hook spring of stretching provided by the utility model, is provided with hook including two ends Spring body, hook and spring body are formed in one structure, by the head and the tail two ends of spring body Extending outward bending to form, the vertical lead division of hook is positioned on the axial line of spring body, On the vertical lead division at spring body two ends, the most slidably it is arranged with connector, the company at two ends Connecting between fitting and have for stretching spacing expansion link, in a free state, expansion link is in Contraction state, when spring body is stretched, expansion link extends under the drive of connector therewith, In the range of the extended length of expansion link is limited to the limit of stretch of spring body, at level of stretch Overstep the extreme limit before position, the length that limits of expansion link lock, spring body can be prevented to be stretched Lost efficacy, can play a protective role, it is possible to avoid causing because stress is excessive the situation of elastic failure.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, The accompanying drawing used required in embodiment or description of the prior art will be briefly described below, It should be evident that the accompanying drawing in describing below is only embodiments more of the present utility model, right From the point of view of those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to Other accompanying drawing is obtained according to these accompanying drawings.

Fig. 1 is stretching provided by the utility model spacing hook spring structural representation.

Detailed description of the invention

Core of the present utility model is to provide the spacing hook spring of a kind of stretching, it is possible to avoid because being subject to The excessive situation causing elastic failure of power.

Below in conjunction with the accompanying drawing in this utility model embodiment, in this utility model embodiment Technical scheme be clearly and completely described, it is clear that described embodiment be only this The a part of embodiment of utility model rather than whole embodiments.Based in this utility model Embodiment, those of ordinary skill in the art are obtained under not making creative work premise Every other embodiment, broadly falls into the scope of this utility model protection.

It is stretching provided by the utility model spacing hook spring structure incorporated by reference to Fig. 1, Fig. 1 Schematic diagram.

The spacing hook spring of a kind of stretching provided by the utility model, is provided with extension including two ends The spring body 1 of hook 11, hook 11 and spring body 1 are formed in one structure, by spring The head and the tail two ends of body 1 extend outward bending and form, the vertical lead division 12 of hook 11 On the axial line of spring body 1, on the vertical lead division 12 at spring body 1 two ends, That slides is arranged with connector 2, and between the connector 2 at two ends, connection has for stretching spacing Expansion link 3.

The spacing hook spring of stretching provided by the utility model, in a free state, expansion link 3 are in contraction state, and when spring body 1 is stretched, expansion link 3 is at the band of connector 2 Extend therewith under Dong, the extended length of expansion link 3 is limited to the limit of stretch of spring body 1 In the range of, before level of stretch oversteps the extreme limit position, the length that limits of expansion link 3 lock, Spring body 1 can be prevented to be stretched inefficacy, can play a protective role, it is possible to avoid because of stress The excessive situation causing elastic failure.

In specific embodiment of the utility model, stretch and set on the connector 2 of spacing hook spring It is equipped with the installing hole for connection expansion link 3, and the two ends of expansion link 3 is provided with screw thread, It is fixed on connector 2 by being arranged at the nut of the upper and lower both sides of the installing hole of connector 2.

Preferably, the spacing hook spring of stretching provided by the utility model, expansion link 3 includes Overcoat and inner core.

Hook spring spacing to stretching provided by the utility model is described in detail above, Principle of the present utility model and embodiment are set forth by specific case used herein, The explanation of above example is only intended to help to understand that method of the present utility model and core thereof are thought Think.It should be pointed out that, for those skilled in the art, without departing from this reality On the premise of new principle, it is also possible to this utility model is carried out some improvement and modification, this A little improvement and modification also fall in this utility model scope of the claims.
