The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element to which the reference is made must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example 1:

a steel wire rope stress buffering device is characterized in that: comprises a middle cylinder 1, a right joint 2 and a left joint 3; the right end of the middle cylinder 1 is in threaded connection with the right connector 2, and the left end of the middle cylinder 1 is in threaded connection with the left connector 3; a sliding inner barrel 6 is arranged in the middle barrel 1; a connecting rod 4 is arranged on one surface of the sliding inner cylinder 6, which is positioned on the right joint 2; the connecting rod 4 penetrates through the right connector 2, and a connector 5 is arranged at the outer end of the connecting rod; a second pressure spring 8 is arranged between the sliding inner cylinder 6 and the right joint 2; and a first pressure spring 7 is arranged between the sliding inner cylinder 6 and the left joint 3. The first pressure spring 7 and the second pressure spring 8 are used for guaranteeing that the buffer device can play an effective buffer role no matter when tension or thrust is received.

A triangular plate 11 is arranged between the connecting rod 4 and the sliding inner cylinder 6; the set square 11 is equipped with a plurality ofly and encircle equidistant being fixed in between connecting rod 4 and the inner tube 6 that slides. The structural design of set-square 11 firstly can play the effect of fixed stay, strengthens connection structure intensity relation, and two also can play the effect of spacing protection when dragging right.

A limiting shaft 12 is arranged on one surface of the sliding inner cylinder 6, which is positioned on the left joint 3; the outer end of the limiting shaft 12 is provided with a spring pad 13. The limiting shaft 12 and the spring pad 13 are used for limiting and protecting the left end of the device when the device is subjected to excessive pulling force.

And the outer end of the left joint 3 is provided with a screw rod 14. The screw rod 14 is used for being installed in a threaded hole of a vehicle needing to be pulled, and connection and fixation are convenient.

The cross-sectional area of the connector 5 is larger than that of the connecting rod 4, and the connector 5 is provided with a hole. Prevent that connector 5 from being drawn inside well 1, causing the inside part dislocation to damage.

The specific implementation mode is as follows:

first pressure spring 7 and second pressure spring 8 cup joint respectively and install in the both ends of sliding inner tube 6, when the pulling power is received to the left end, second pressure spring 8 plays the cushioning effect, and when the pulling power is received to the right end, first pressure spring 7 plays the cushioning effect.

Example 2:

the specific differences between example 2 and example 1 are:

two ends of the second pressure spring 8 are respectively welded on the sliding inner cylinder 6 and the right joint 2; and two ends of the first pressure spring 7 are respectively welded on the sliding inner cylinder 6 and the left joint 3. Because first pressure spring 7 and second pressure spring 8 adopt the welding mode to fix, consequently first pressure spring 7 and second pressure spring 8 can play the cushioning effect simultaneously when receiving the power, consequently its shock-absorbing capacity obtains improving greatly, but then comparatively loaded down with trivial details in the installation than in embodiment 1.

A clamping groove 9 is formed in the inner wall of the middle barrel 1; a limiting plate 10 is arranged on the periphery of the sliding inner cylinder 6; the cross section of the limiting plate 10 is in an isosceles trapezoid structure. The number and the position of the limiting plates 10 correspond to those of the slots 9, and the limiting plates are clamped in the slots 9. Therefore, the first pressure spring 7 and the second pressure spring 8 adopt a welding mode, radial limitation is carried out on the sliding inner cylinder 6, the first pressure spring 7 and the second pressure spring 8 are guaranteed not to be subjected to radial force, and the service life of the first pressure spring 7 and the service life of the second pressure spring 8 are prolonged.

The specific implementation mode is as follows:

install the device in the required screw hole of dragging the vehicle through lead screw 14, be convenient for connect fixedly, hang wire rope in the trompil on connector 5 simultaneously, when dragging connector 5, the extrusion of second pressure spring 8, first pressure spring 7 are tensile, and both provide the buffer power simultaneously, and when extrusion connector 5, extrusion of first pressure spring 7, second pressure spring 8 are tensile, and its effect is as follows, therefore no longer explains.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
