Abstract
The invention discloses an extension spring. The extension spring comprises a large-diameter spring, a small-diameter spring, a hook, a hanging ring, a protrusion and spring connecting blocks. The extension spring is characterized in that the large-diameter spring is connected with the small-diameter spring, the hanging ring is arranged above the large-diameter spring, the hook is arranged below the small-diameter spring, the protrusion is arranged on the top of the hook, and the large-diameter spring and the small-diameter spring are both composed of a plurality of small springs which are connected through the spring connecting blocks. The extension spring is simple in structure and convenient to operate. Due to the cooperation of the large-diameter spring and the small-diameter spring, the extension spring can be extended in various mode. Meanwhile, the protrusion on the hook can prevent an article on the hook from falling off; due to the arrangement of the spring connecting blocks, the over-fatigue springs can be replaced, cost is saved, and use is convenient.
Description
Technical field
The present invention relates to a kind of spring, be specially a kind of extension spring.
Background technique
Spring is a kind of mechanical parts utilizing elasticity to carry out work, generally makes with spring steel, in order to control the motion of parts, relax and impact or vibrations, storage or saving energy, the size etc. of measuring force, is widely used in machine, in instrument, spring is an accumulator just, it has the function of stored energy, but at leisure fault offset out, can not to realize this function of slow release and " spring+big speed ratio mechanism " should be leaned on to realize, be common in mechanical watch, spring just applied very early, the bow in ancient times and crossbow are exactly two kinds of sensu lato springs, and by stressed character, spring can be divided into extension spring, Compress Spring, torsion spring and flexural spring, can be divided into belleville spring by shape, annular spring, leaf spring, helical spring, valute spring and torsion bar spring etc., can be divided into cold coiling spring and hot coiling spring by working process, and common cylinder spring is simple owing to manufacturing, and various types can be made according to loading conditions, structure is simple, therefore most widely used, and in general the manufactured materials of spring should have high limit of elasticity, fatigue limit, impact toughness and good heat treatment performance etc., conventional has carbon spring steel, alloy spring steel, rustproof spring steel and Cuprum alloy, nickel alloy and rubber etc., the manufacture method of spring has cold coiling method and hot rolling method, the general cold coiling method that wire diameter is less than 8 millimeters, be greater than 8 millimeters use hot rolling method, some spring also will carry out suppressing or shot blast after it has been manufactured, can improve the bearing capacity of spring.
Extension spring is that a kind of machinery stores power structure, extensive use in modern industry, but existing extension spring, the spring body comprising one and the be located at spring body two ends first hook and second are linked up with, and described spring body forms hollow cylinder by the curling superposition of metal wire rod, and described hollow cylinder comprises inner circle, when connecting, must rely on the hook at its two ends, Placement is less, connects also stable not.
Summary of the invention
The object of the present invention is to provide a kind of extension spring, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technological scheme: a kind of extension spring, comprise large diameter spring, little diameter spring, hook, suspension ring, projection and spring contiguous block, it is characterized in that: described large diameter spring is connected with little diameter spring, be provided with suspension ring above described large diameter spring, be provided with hook below described little diameter spring, described hook top is provided with projection, described large diameter spring and little diameter spring are made up of multiple little spring, are connected by spring contiguous block between described little spring.
Preferably, the diameter of described little diameter spring is the half of large diameter spring.
Preferably, the Placement of described suspension ring and large diameter spring is welding manner.
Preferably, the cross-sectional diameter of described projection is greater than the diameter of hook cross-section.
Compared with prior art, the invention has the beneficial effects as follows: a kind of extension spring, structure is simple, easy to operate, by coordinating of large diameter spring and little diameter spring, various ways can be selected to carry out extension spring, meanwhile, the projection on hook can prevent the thing linked up with from dropping, and the setting of spring contiguous block can make the spring of excessive fatigue to change, save cost, facilitate use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, large diameter spring, 2, little diameter spring, 3, hook, 4, suspension ring, 5, projection, 6, spring contiguous block.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the invention provides a kind of technological scheme: a kind of extension spring, comprise large diameter spring 1, little diameter spring 2, hook 3, suspension ring 4, projection 5 and spring contiguous block 6, it is characterized in that: described large diameter spring 1 is connected with little diameter spring 2, suspension ring 4 are provided with above described large diameter spring 1, hook 3 is provided with below described little diameter spring 2, described hook 3 top is provided with protruding 5, described large diameter spring 1 and little diameter spring 2 are made up of multiple little spring, are connected by spring contiguous block 6 between described little spring.
The described cross-sectional diameter of protruding 5 is greater than the diameter of hook 3 cross section, and described suspension ring 4 are welding manner with the Placement of large diameter spring 1, and the diameter of described little diameter spring 2 is half of large diameter spring 1.
Concrete usage mode: the present invention in use, suspension ring 4 are for fixing extension spring, by the cooperation of large diameter spring 1 and little diameter spring 2, various ways can be selected to carry out extension spring, simultaneously, projection 5 on hook 3 can prevent the thing on hook 3 from dropping, and the setting of spring contiguous block 6 can make the spring of excessive fatigue to change.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any reference character in claim should be considered as the claim involved by limiting.
