Description
Technical field
This utility model relates to spring art, particularly to a kind of torsion spring.
Background technology
The purposes of spring widely, the almost indispensable element of common mechanical, when it is by External Force Acting, i.e. produces elastic deformation, thus store strain energy and discharge at random.At the torsion spring of spring kind apoplexy due to endogenous wind, also known as twins torsion spring, as the term suggests being made up of two spring bodies, being dependent on its torsional elasticity and producing frictional force with transmission power or the spring of motion.
The patent document of China Patent Publication No. CN203297447U discloses a kind of novel torsion spring, including the first spring body being oppositely arranged and the second spring body, it is characterized in that, the centrage of the first described spring body and the centrage of the second spring body overlap, the first described spring body is connected near one end of the first spring body with the second described spring body by arch connecting rod near one end of the second spring body, the first described spring body other end connects the first mounting rod, the second described spring body other end connects the second mounting rod, and the first described mounting rod and the second mounting rod arranged in parallel, first mounting rod is provided with the first position limiting structure, second mounting rod is provided with the second position limiting structure.Although technique scheme achieves the effect that spring stability is high, but the arch length of connecting rod of this torsion spring is certain, so that its restricted application, it is impossible to apply to multiple occasion, it is impossible to be changed according to practical situation, cause trouble is installed.
Utility model content
The purpose of this utility model is to provide a kind of torsion spring, by the first link arm that is sheathed and that be slidably connected and the second link arm, achieve the first spring body and the second spring body can be applicable to bigger scope, it is achieved the scalable of the spacing of the first spring body and the second spring body, make easy for installation.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of torsion spring, including connecting the first spring body of there being the first link arm and connecting and have the second spring body of the second link arm, described first link arm is sheathed and is slidably connected to the second link arm, described first link arm and the second link arm junction and is provided with and realizes the first spring body and the second spring body fixes the fixture of connection.
By using technique scheme, second link arm can be extend in the first link arm, slide inside the first link arm, such that it is able to the distance changed between the first spring body and the second spring body, expand the scope of application of torsion spring, the distance of torsion spring interlude can be changed according to actual installation situation, install it is thus possible to convenient, the length that will not be fixed by torsion spring and limit, may cause troublesome problem is installed, it is also possible to be applicable to multiple installation environment, and then enable torsion spring to be adapted to more occasion, increase operation rate, use more convenient.
This utility model is further arranged to: described first link arm inner peripheral surface is provided with groove along its length, and described second link arm outer circumference surface is provided with fin along its length, and described fin is embedded and is slidably connected to groove.
By using technique scheme, can utilize groove and fin is embedded effect, first, second link arm has been carried out a spacing interconnection function, avoid relatively rotating between the first spring body and the second spring body and affecting the symmetry of torsion spring, can only relatively slide and cannot rotate, also providing a guiding for slip, the relative slip making both can be more smooth and easy.
This utility model is further arranged to: described first link arm is provided with the first screwed hole in vertical direction near second link arm one end outer circumference surface, described fin upper surface is provided with draw-in groove along its length, described fixture and the first screwed hole are threaded, and described fixture bottom surface is arranged in conflicting with draw-in groove.
By using technique scheme, fixture is utilized to realize the fixing interconnection function of the first link arm and the second link arm, the length that only the second link arm need to be pulled to stretch out the first link arm just can regulate the distance between the first spring body and the second spring body, recycling fixture contacts at the surface of draw-in groove, just by the frictional force of fixture and card rooved face, the second link arm can be applied a drag effect, and then prevent torsion spring from use departing between the first spring body and the second spring body.
This utility model is further arranged to: described first spring body and the second spring body are respectively further from one end of first, second link arm and are removably connected with hook.
By using technique scheme, it is capable of torsion spring and has hook and the two states without hook, such that it is able to select according to practical situation, meet more actual installation condition, and then make installation more convenient, also can utilize hook that torsion spring plays connection fixation in some cases；When need not hook, hook can be removed again.
This utility model is further arranged to: described first spring body and the second spring body are respectively further from one end of first, second link arm and are threaded with hook.
By use technique scheme: utilize threaded by the way of realize hook removably connect, the type of attachment of which is convenient, the most more locking property, and both bond strengths when combining are higher.
In sum, this utility model has the advantages that and can realize the first link arm and the regulation of the second link arm length, the distance between the first spring body and the second spring body can be changed according to actual installation situation, and by fixture and the first screwed hole and the annexation of draw-in groove, it is achieved the fixing interconnection function to first, second link arm.
