Abstract
The utility model discloses a spring used for a break-brake switch. The spring used for the break-brake switch comprises an integrated spring body and a hook which is arranged at one end of the spring body, the spring body is a hollow cylinder which is formed by metal wire materials in a curling and overlaying mode, no hook is arranged at the other end of the spring body, the diameter of the section, corresponding to the end with no hook, of the spring is lessened gradually and form a horn mouth shape, and an opening is formed in a small head end of the horn mouth. According to the spring used for the break-brake switch, the end, with the hook, of the spring is fixed, and a bolt is installed at the other end of the spring. The end, with the bolt, of the spring is a large head end which is clamped in the horn mouth. The section, provided with a thread, of the bolt stretches out from the opening and is in threaded connection with a fixed nut. Through adjustment of the threaded connection of the bolt and the nut, namely the nut is rotated, the bolt can be adjusted forward or backward, and adjustment of tightness degree of the spring used for the break-brake switch can be achieved.
Description
Technical field
The utility model relates to a kind of spring, especially a kind of spring for the separating brake switch.
Background technique
Spring is a kind of mechanical parts that utilize elasticity to come work.Generally make with spring steel.Impact or shake, store up the size of energy, measuring force etc. in order to motion, the mitigation of controlling parts, be widely used in machine, the instrument.Spring is an accumulator just, and it has the function of stored energy, but can not discharge energy at leisure, realize that this function of slow release should lean on " spring+big speed ratio mechanism " to realize, is common in mechanical watch.Spring had just been used very early, and the bow in ancient times and crossbow are exactly two kinds of sensu lato springs.By stressed character, spring can be divided into extension spring, Compress Spring, torsion spring and flexural spring, belleville spring, annular spring, leaf spring, helical spring, valute spring and torsion bar spring etc. can be divided into by shape, cold coiling spring and hot coiling spring can be divided into by working process.The common cylinder spring is simple owing to making, and can make various types according to the stand under load situation, and is simple in structure, so most widely used.In general the manufactured materials of spring should have high limit of elasticity, fatigue limit, impact toughness and good heat treatment performance etc., and commonly used have carbon spring steel, alloy spring steel, rustproof spring steel and Cuprum alloy, nickel alloy and a rubber etc.The manufacture method of spring has cold coiling method and hot rolling method.The spring thread diameter is less than 8 millimeters the general cold coiling method of using, greater than 8 millimeters use the hot rolling method.Some spring also will be suppressed or shot blast after making, and can improve the bearing capacity of spring.
Existing a lot of electrical equipment all need to use the separating brake switch, disconnect and close up.Existing separating brake switch all is to control the disconnection of separating brake switch and close up by an extension spring, and all there is hook at the extension spring two ends, by the fixing hook at two ends, realizes resetting of extension spring so that extension spring has certain active force to switch.There is a shortcoming in it, be exactly extension spring time one long, easy elongated fluffing so that its pulling force is inadequate, and that its two ends are is fixing, can't regulate.Affect resetting of separating brake switch, be prone to accidents.
The model utility content
Problem to be solved in the utility model is to improve in the background technique problem that can't regulate after the fluffing of the spring that is used for the separating brake switch.
In order to overcome the above problems, the utility model provides a kind of spring for the separating brake switch, comprise the spring body of one and be located at the hook of spring body one end, described spring body forms hollow cylinder by metal wire rod curling stack worker, the other end of described spring body is hook not, and the corresponding one section spring diameter of this end dwindles gradually and forms a toroidal, and described bell-mouthed little head end is provided with an opening.
Described spring body is stainless steel.
The external diameter of described spring body is 4 centimetres to 6 centimetres.
Spring for the separating brake switch described in the utility model, comprise the spring body of one and be located at the hook of spring body one end, described spring body forms hollow cylinder by metal wire rod curling stack worker, the other end of described spring body is hook not, and the corresponding one section spring diameter of this end dwindles gradually and forms a toroidal, described bell-mouthed little head end is provided with an opening, spring for the separating brake switch described in the utility model, hook end is fixed, the other end is equipped with a bolt, one end of bolt is stub end, stub end is stuck in bell-mouthed the inside, bolt is established threaded one section and is stretched out from opening, be threaded with fixing nut, by being threaded of adjusting bolt and nut, i.e. rotary nut, can adjusting bolt advance or retreat reaches the tightness of regulating the spring for the separating brake switch described in the utility model.
Description of drawings
Accompanying drawing 1 is the spring schematic representation for the separating brake switch described in the utility model
1, spring body; 11, hook; 12, toroidal.
Embodiment
Below in conjunction with accompanying drawing a kind of spring for the separating brake switch of the utility model is described further.
As shown in Figure 1, the spring that is used for the separating brake switch of present embodiment, comprise the spring body 1 of one and be located at the hook 11 of spring body 1 one ends, spring body 1 forms hollow cylinder by metal wire rod curling stack worker, the other end of spring body 1 is hook not, and the corresponding one section spring diameter of this end dwindles gradually and forms a toroidal 12, and bell-mouthed little head end is provided with an opening.Spring for the separating brake switch described in the utility model, hook end is fixed, the other end is equipped with a bolt, and an end of bolt is stub end, and stub end is stuck in bell-mouthed the inside, bolt is established threaded one section and is stretched out from opening, be threaded with fixing nut, by being threaded of adjusting bolt and nut, i.e. rotary nut, can adjusting bolt advance or retreat reaches the tightness of regulating the spring for the separating brake switch described in the utility model.
In the present embodiment, described spring body 1 is stainless steel.Better rustless property can be reached, the environment of the humidity in bathroom can be adapted to, long service life.In the present embodiment, the external diameter of described spring body 1 is 4 centimetres to 6 centimetres.This design so that spring preferably water pipe pass, reach better about the water pipe location.
The utility model is not limited to above embodiment and conversion.
