Abstract

The utility model discloses a telescopic spring bolt, including the bolt body, the bolt body include spiral shell head, spring, screw rod, the spiral shell head be regular hexagon spatial structure, the lower extreme is connected the spring, the spring extend to connect the screw rod, the screw rod be the cylinder structure, be close to the screw rod surface of one end of spring be provided with the screw thread, another tail end is smooth surface, wherein, the spring compression of can stretching comes the length change adjustment to the bolt through this. In this way, the utility model discloses novel structure, the design of the spring that increases newly for the overall length of bolt can be finely tuned as required, and the design is practical, reasonable, convenient to use, and strong adaptability, the rate of utilization is high.

Description

A kind of Telescopic spring bolt

Technical field

The utility model relates to fixed component field, particularly relates to a kind of Telescopic spring bolt.

Background technique

Bolt is the one of mechanical parts, the cylindrical threaded fastening piece of adapted nut, by head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, need and nut screw connection, for being fastenedly connected two parts with through hole, this Connecting format claims bolt to connect, as nut is screwed off from bolt, can make again these two parts separately, therefore bolt connection belongs to removably connect, and at present, the bolt on market is mostly fixing, length is unadjustable, not humane.

Model utility content

The technical problem that the utility model mainly solves is to provide a kind of Telescopic spring bolt, and the overall length of bolt can be made to finely tune as required, and utilitarian design, rationally, easy to use, strong adaptability, utilization rate is high.

For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of Telescopic spring bolt, it is characterized in that, comprising: bolt body, described bolt body comprises spiral shell head, spring, screw rod, described spiral shell head is regular hexagon stereochemical structure, spring described in lower end connects, described spring extends the screw rod described in connecting, and described screw rod is cylindrical structure, screw surface near one end of described spring is provided with screw thread, and another tail end is smooth surface; Wherein, spring can carry out Compression and Expansion, is adjusted by this length change to bolt.

In the utility model preferred embodiment, described spring is made up of hard spring steel, and when leaving standstill, length is 1.5cm, and the minimum length after compression is 0.5cm, and stretchable extreme length is 3cm, and namely telescopic extensions is 0.5-3cm.

In the utility model preferred embodiment, described spiro rod length is 2.5cm, and diameter of section is identical with described width of the spring, and the 2cm screw surface near spring place is provided with screw thread, and tail end 0.5cm is smooth surface.

In the utility model preferred embodiment, described spiral shell head, screw rod material are round steel.

In the utility model preferred embodiment, described bolt body overall length, the telescopic extensions except spiral shell head thickness is 3-5.5cm, and overall length when leaving standstill is 4cm except spiral shell head thickness.

The beneficial effects of the utility model are: the utility model novel structure, the design of the spring newly increased, and the overall length of bolt can be finely tuned as required, and utilitarian design, rationally, easy to use, strong adaptability, utilization rate is high.

Accompanying drawing explanation

In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:

Fig. 1 is the structural representation of a kind of Telescopic spring bolt one of the utility model preferred embodiment;

In accompanying drawing, the mark of each parts is as follows: 1, bolt body; 2, spiral shell head; 3, spring; 4, screw rod; 5, screw thread.

Embodiment

Be clearly and completely described to the technological scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1, the utility model is embodiment comprise:

A kind of Telescopic spring bolt, it is characterized in that, comprise: bolt body 1, described bolt body comprises spiral shell head 2, spring 3, screw rod 4, and described spiral shell head 2 is regular hexagon stereochemical structure, the spring 3 described in lower end connects, described spring 3 extends the screw rod 4 described in connecting, described screw rod 4 is cylindrical structure, and the screw surface near one end of described spring 3 is provided with screw thread 5, and another tail end is smooth surface; Wherein, spring 3 can carry out Compression and Expansion, is adjusted by this length change to bolt 1.

Be different from prior art.

In another embodiment, described spring 3 is made up of hard spring steel, and when leaving standstill, length is 1.5cm, and the minimum length after compression is 0.5cm, and stretchable extreme length is 3cm, and namely telescopic extensions is 0.5-3cm; Described screw rod 4 length is 2.5cm, and diameter of section is identical with described spring 3 width, and be provided with screw thread 5 near 2cm screw rod 4 surface at spring 3 place, tail end 0.5cm is smooth surface; Described spiral shell head 2, screw rod 4 material are round steel, material aboundresources, and cost is low, simply easy to process; Described bolt 1 body overall length, the telescopic extensions except spiral shell head thickness is 3-5.5cm, and overall length when leaving standstill is 4cm except spiral shell head thickness.

The utility model novel structure, the design of spring, the overall length of bolt can be finely tuned as required, according to required fastening object thickness, carry out stretching or compress described bolt, finely tune, fastening, do not need the bolt preparing sizes, convenient and practical, strong adaptability, utilization rate is high.

The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
