Abstract
The utility model discloses a spiral spring with changeable length, including the spring body, spring body top is provided with interior pole, spring body bottom is provided with the loop bar, the loop bar internal diameter is than the big 0.2mm~0.5mm of interior shank diameter, the inside screw hole that all is provided with of interior pole and loop bar, the screw hole equidistance is equipped with three groups at least, interior pole surface is provided with the cylinder, the cylinder runs through interior pole, and the cylinder diameter all is greater than loop bar internal diameter 0.2mm~0.5mm. This product simple structure, convenient operation, application scope is wide, need not the coil spring according to the specific length of specific applications occasion customization, has practiced thrift the cost to the cycle has been shortened.
Description
Technical field
This utility model belongs to helical spring technical field, is specifically related to a kind of adjustable length helical spring.
Background technology
Spring is a kind of machine components utilizing elasticity to carry out work, in order to control the motion of parts, to relax impact or vibrations, storage or saving energy, the size etc. of measurement power, is widely used in machine, instrument.Traditional helical spring has a variety of length specification, uses the spring of different length according to different occasions.But in some occasion, just it is difficult to search out the spring of appropriate length, can only customize, add cost and cycle.
Utility model content
The purpose of this utility model is to provide a kind of adjustable length helical spring, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of adjustable length helical spring, including spring body, described spring body top is provided with interior bar, it is provided with loop bar bottom described spring body, being provided with screwed hole inside described interior bar and loop bar, described interior bar surface configuration has cylinder.
Preferably, described loop bar internal diameter 0.2mm～0.5mm bigger than interior shank diameter.
Preferably, described cylinder runs through interior bar, and column diameter is all higher than loop bar internal diameter 0.2mm～0.5mm.
Preferably, described screwed hole is equidistant at least provided with three groups.
nullTechnique effect of the present utility model and advantage: this adjustable length helical spring，When needing the length adding long helix spring，Two spring body can be joined end to end，Because of loop bar internal diameter 0.2mm～0.5mm bigger than interior shank diameter，Within, bar can stretch into the inside of loop bar，Column diameter on interior bar is stuck in set boom end more than loop bar internal diameter therefore cylinder，The most just make the screwed hole within interior bar and loop bar symmetrical，Location nut penetrates screwed hole and runs through interior bar and loop bar，The threaded one end of location nut connects nut，Interior bar and loop bar are fixed together by location nut and nut，Screwed hole is at least provided with three groups of stability that can strengthen between spring body and spring body，When needing the length shortening helical spring，Have only to remove location nut，Then a spring body is removed，This product structure is simple，Easy to operate，Applied widely，Without the helical spring according to concrete application scenario customization length-specific，Save cost，And shorten the cycle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation under this utility model connection status.
In figure: 1 spring body, bar, 3 loop bars, 4 screwed holes, 5 cylinders, 6 location nut, 7 nuts in 2.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
This utility model provides the adjustable length helical spring of one as shown in Figure 1-2, including spring body 1, described spring body 1 top is provided with interior bar 2, it is provided with loop bar 3 bottom described spring body 1, described interior bar 2 and loop bar 3 inside are provided with screwed hole 4, and described interior bar 2 surface configuration has cylinder 5.
Further, described loop bar 3 internal diameter is than interior bar 2 big 0.2mm～0.5mm of diameter.Within, bar 2 can stretch into the inside of loop bar 3.
Further, described cylinder 5 runs through interior bar 2, and cylinder 5 diameter is all higher than loop bar 3 internal diameter 0.2mm～0.5mm.Therefore cylinder 5 can only be stuck in loop bar 3 end.
Further, described screwed hole 4 is equidistant at least provided with three groups.The stability between spring body 1 and spring body 1 can be strengthened.
nullThis adjustable length helical spring，When needing the length adding long helix spring，Two spring body 1 can be joined end to end，Because loop bar 3 internal diameter is than interior bar 2 big 0.2mm～0.5mm of diameter，Within, bar 2 can stretch into the inside of loop bar 3，Cylinder 5 diameter on interior bar 2 is stuck in loop bar 3 end more than loop bar 3 internal diameter therefore cylinder 5，The most just make the screwed hole 4 within interior bar 2 and loop bar 3 symmetrical，Location nut 6 penetrates screwed hole 4 and runs through interior bar 2 and loop bar 3，The threaded one end of location nut 6 connects nut 7，Interior bar 2 and loop bar 3 are fixed together by location nut 6 and nut 7，Screwed hole 4 is at least provided with three groups of stability that can strengthen between spring body 1 and spring body 1，When needing the length shortening helical spring，Have only to remove location nut 6，Then a spring body 1 is removed，This product structure is simple，Easy to operate，Applied widely，Without the helical spring according to concrete application scenario customization length-specific，Save cost，And shorten the cycle.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; it is not limited to this utility model; although this utility model being described in detail with reference to previous embodiment; for a person skilled in the art; technical scheme described in foregoing embodiments still can be modified by it; or wherein portion of techniques feature is carried out equivalent; all within spirit of the present utility model and principle; the any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
