Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of the utility model protection; Wherein involved in this enforcement "and/or" keyword, represent and or two kinds of situations, in other words, A and/or B mentioned by the embodiment of the present invention, illustrates A and B, A or B two kinds of situations, describes three kinds of states existing for A and B, as A and/or B, represent: only include A and do not comprise B; Only include B and do not comprise A; Comprise A and B.
The crashproof limit switch of the one that the utility model embodiment provides, this crashproof limit switch is by arranging elastic parts, when making equipment collision sensing part, induction pieces realizes moving relative to support cover by elastic parts, overcome when device action stops in prior art and knock limit switch because inertia continues forward motion, cause the technological deficiency that limit switch damages.
Specifically, this crashproof limit switch at least comprises: induction pieces, support cover and elastic parts.Wherein, the top of support cover is provided with first interface, bottom is provided with the second interface, the conducting orifice that this first interface is come in and gone out as induction pieces, realize induction pieces is moved to support cover by the outside of support cover inside by first interface, this second interface is as the access port external wire pipe of outer lead pipe, the inside of support cover is hollow cavity body structure so that hold induction pieces and elastic parts, and elastic parts respectively with the bottom of induction pieces, the bottom of support cover is fixedly connected with, make (when equipment does not clash into induction pieces) under normal circumstances, induction pieces is positioned at the over top of support cover under the elastic force of elastic parts supports, elastic parts is positioned at the internal cavity structure of support cover.When equipment because first direct during inertia continuation forward motion and induction pieces collide, by the induction pieces that collides by elastic parts generation elastic deformation, and then start to carry out moving (elasticity of compression assembly moves towards the bottom direction of support cover) relative to support cover, make the induction pieces in moving process under the elastically-deformable effect of elastic parts, cut down the impact of action equipment gradually, effectively prevent when not arranging elastic parts, equipment continues the dynamic defect directly breaking limit switch forward due to inertia, has the advantages that security performance is high.
In the utility model embodiment, induction pieces can by being square or stereochemical structure parts that are spherical or other planforms of having that ordinary hard requirement material makes, for contacting with the direct collision of action equipment, but it is preferred, in this crashproof limit switch, induction pieces is the crashproof portion 1 in dome-type, can as shown in Figure 1, and the bottom surface in this crashproof portion 1 is as connection plane, is fixedly connected with the top of elastic parts.Because induction pieces in the utility model embodiment adopts the crashproof portion 1 in dome-type, make the sphere in crashproof portion 1 as collision end face, action equipment on any one direction can be detected and then collide with it, expand the detection range of induction pieces, overcome the detection that limit switch general in prior art can only carry out on one side detection or a line, and then the defect making the scope of application of limit switch narrow.
In the utility model embodiment, refer to Fig. 1-2, support cover can at least comprise: cover body 2 and support ring 3.Wherein, the top of cover body 2 offers first interface, the bore of first interface and the diameter in crashproof portion 1 suitable (being more than or equal to), make crashproof portion 1 under the collision effect of action equipment, moved to the inside of cover body from first interface by the outside of cover body 2.Refer to Fig. 3, support ring 3 structure in the form of a ring, and the middle part of support ring 3 is provided with above-mentioned second interface, so that external wire pipe, realize foreign current and transfer to support ring 3 and cover body 2 place successively by conduit, make the inside cavity of cover body 2 produce magnetic field, and then send the actual range of field signal sensing apparatus relative to crashproof portion 1 in any direction by the even sphere in crashproof portion 1; Meanwhile, the edge of support ring 3 is fixedly connected with the bottom of cover body 3, and elastic parts is fixed on the upper surface place of support ring 3, so that support crashproof portion 1.
In the utility model embodiment, elastic parts can be spring, or rubber, or other have the compliant member of elastic deformation function, with realize action equipment clash into crashproof portion 1 time, crashproof portion 1, by the impact of elasticity of compression assembly generation elastic deformation damping action equipment, finally protects crashproof portion 1 and whole limit switch.In the present embodiment, elastic parts can at least comprise: several springs 4 and several flexible pipe boxes.Wherein, spring 4 and telescoping tube overlap that quantity is corresponding identical, and one end of spring 4 is fixedly connected with support ring 3, and the other end of spring 4 is fixedly connected with the bottom in crashproof portion 1, makes spring 4 be positioned at the inside of cover body 2; And flexible pipe box one_to_one corresponding is set in the outside of each spring 4, with support spring 4, prevents the situation that spring 4 occurs distortion, skews in compression process.Preferably, spring 4 can be all three with the quantity of telescopic tube, and three equally spaced upper surface places being arranged on support ring 3 of spring 4/ telescopic tube, so that spring 4 stress equalization.
In the utility model embodiment, for make spring 4 be connected between support ring 3 or crashproof portion 1 fastening, in the process of Compress Spring 4, there is the phenomenons such as spring 4 comes off, ejection to prevent crashproof portion 1, preferably, being fixedly connected with between spring 4 with support ring 3, being fixedly connected with between spring 4 with crashproof portion 1 can be all weld.
The crashproof limit switch of the one that the utility model provides, its beneficial effect is as described below:
1., the utility model is by arranging elastic parts, and the top of support cover is provided with first interface, when making equipment collision sensing part, induction pieces is moved to the inside of support cover by the outside of support cover by first interface, induction pieces in moving process cuts down the impact of action equipment gradually under the elastically-deformable effect of elastic parts, effectively prevents equipment due to the inertia continuation dynamic defect directly breaking limit switch forward;
2., in the utility model, induction pieces is the crashproof portion 1 of dome-type by employing, make the sphere in crashproof portion 1 as collision end face, action equipment on any one direction can be detected and then collide with it, expand the detection range of induction pieces, overcome the detection that limit switch general in prior art can only carry out on one side detection or a line, and then the defect making the scope of application of limit switch narrow;
3., pass through support ring 3 to adopt circulus in the utility model, and the middle part of support ring 3 arranges the second interface to connect conduit, achieve foreign current and transfer to support ring 3 and cover body 2 place successively by conduit, make the inside cavity of cover body 2 by importing current induced magnetic field, and then send the actual range of field signal sensing apparatus relative to crashproof portion 1 in any direction by the even sphere in crashproof portion 1;
