The load quick releasing device of the utility model has the advantages that the installation is simple, the structure miniaturization can be realized, the action execution is free from environmental medium or atmosphere except the temperature, the action response speed is high, the reliability is good, the cost is low, and the load quick releasing device can be taken as an automatic control component and used for mechanical industries, automated industries and electronic industries.
Description
Technical field
The utility model belongs to signal of telecommunication export technique field, particularly a kind of marmem load quick release device.
Background technology
Shape memory effect is meant that the alloy of certain original shape is out of shape the back at low temperatures by being heated to a kind of property that can return to original shape more than a certain critical temperature.After shape-memory alloy wire carries out stretcher strain at low temperatures, to its heating, it will produce recovery of shape displacement and restoring force, utilize its restoring force and reply the characteristic that displacement can externally do work and make various driving elements and executive component, in machinery and automatic industrial, be used widely at present, for example automatic control equipment such as robot, this mechanism has good reproducibility, simple in structure, highly sensitive, the advantage of good reliability.
Adopt many can the recycling of temperature alarm that marmem makes in the market, but still have some drawbacks, be easy to generate electric arc and shape-memory alloy wire movement response speed waits more slowly as the Metallic rod contact.In addition,,, exist some to need automatic unlocking, object separation as aerospace field in some fields that manually can't operate, and the demand of load release aspect.Therefore, provide a kind of and for machinery and automatic industrial significance is arranged by dop special shape design and the marmem load quick release mechanism that can fix and discharge the load object of certain mass.
The utility model content
The utility model provides a kind of marmem load quick release device especially in order to solve the deficiencies in the prior art.
The technical solution of the utility model is as follows:
A kind of marmem load quick release device, described releasing device comprises:
Fixture is made up of marmem C shape dop 1;
Jockey is made up of yi word pattern montant 2, spring 4, magnet 5 and load object 6,
Casing device is made up of magnetic induction coil 7 and housing 3, and its center, middle shell 3 upper end has the circular hole of a diameter greater than yi word pattern montant 2 diameters; Housing 3 outside the latter halfs are wrapped in magnetic induction coil 7;
The center hole of this housing 3 is passed in yi word pattern montant 2 upper ends, and is meshed with marmem C shape dop above housing 3; Yi word pattern montant 2 lower ends link to each other with load 6 with magnet 5 in housing 3 successively; Spring 4 is enclosed within on the yi word pattern montant 2, is fixed between housing 2 inwalls and the magnet 5; Wherein yi word pattern montant 2 upper ends are spherical shape, and there is a circle groove ball lower end, and load 6 position in housing 3 of connecting, yi word pattern montant 2 lower ends is higher than housing 3 outside the latter halfs and is wrapped in magnetic induction coil 7.
Load quick release mechanism of the present utility model has to be installed simply, but implementation structure miniaturization, its action is carried out and not influenced by temperature surrounding medium or atmosphere in addition, and has the reaction quick action, good reliability, low cost and other advantages can be used as automatic control device and is widely used in mechanical industry, fields such as automatic industrial and electronics industry.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Wherein 1 is marmem C shape dop, and 2 is the yi word pattern montant, and 3 is housing, and 4 is spring, and 5 is magnet, and 6 is the load object, and 7 is magnetic induction coil.
Embodiment
With reference to Fig. 1, center, housing 3 upper end has a slightly larger in diameter in the circular hole of shank diameter, yi word pattern montant 2 passes this center hole, and the ball groove that has by its upper end is meshed with marmem C shape dop above housing, and yi word pattern montant 2 lower ends then link to each other with load object 6 with magnet 5 in housing.Spring 4 is enclosed within on the yi word pattern montant 2, and the upper end is fixed on housing 3 inwalls, and lower end and magnet 5 contact.Housing outer wall the latter half is wrapped in magnetic induction coil 7.The effect of biasing spring 4 is: when marmem C shape dop opens at a certain temperature, make in-line montant 2 break away from marmem C shape dop and decline rapidly by its tension force.Marmem C shape dop enters housing below magnetic induction coil winding zone in the process that descends, because the magnet cutting magnetic line of its connection produces electromotive force, then can export the signal of telecommunication to the outside.
The course of work of marmem load relieving mechanism of the present utility model is as follows:
(1) each parts of design organization are enclosed within biasing spring 4 on the in-line montant 2 and the upper end is fixed on the housing 3 upper end inwalls, and spring lower end and magnet 5 contact.There is groove to a certain degree the in-line montant upper end that makes by processing.
(2) select suitable shape memory alloy material, process the C shape dop 1 that is complementary with in-line montant both-end groove, adopt special experimental tool that marmem C shape dop 1 is carried out pre-tension deformation then and make that width is just in time suitable with grooves on two sides place, yi word pattern montant 2 upper end diameter between its two ends.Marmem C shape dop 1 and in-line montant upper end engagement are finished assembling.
(3) when ambient temperature reaches 1 phase transformation of marmem C shape dop and finishes temperature, marmem C shape dop 1 is replied, because marmem will shrink, width between the marmem dop two ends will strengthen, this moment, dop just can not closely block the in-line montant 2 that is connected with the load object, under the effect of biasing spring 4, in-line montant 2 breaks away from marmem C shape dop 1 and glides rapidly, in the downslide process, in-line montant 2 is through magnetic induction coil 7 zones of housing lower end, and magnet 5 cutting magnetic lines that in-line montant 2 is connected produce the signal of telecommunication and export by external circuit.So just reached the purpose of load object rapid release, meanwhile, to the outside output signal of telecommunication.
