Abstract
The utility model discloses a self-adaption device of a proximity switch. The self-adaption device comprises a fixed seat and a proximity switch body which is arranged on the fixed and can move relatively; the proximity switch body comprises a front end fixing nut and a rear end fixing nut; the fixed seat is located between the front end fixing nut and the rear end fixing nut; and an elastic buffer structure is arranged between the front end fixing nut and the rear end fixing nut. As the elastic buffer structure is arranged on the proximity switch, the proximity switch is effectively prevented from being damaged in collision.
Description
Technical field
The utility model relates to a kind of near switch, and in particular, what relate to is a kind of self-reacting device near switch.
Background technology
In all kinds of switches, have a kind of to element---the displacement transducer of " perception " ability is arranged near its object.Utilize displacement transducer that the sensitivity characteristic near object is reached the purpose of control switch on-off, Here it is near switch.Shift near switch as object, and when being close to certain distance, displacement transducer just has " perception ", switch just can move.Usually cry " detecting distance " this distance.Different detects also difference of distance near switch.
Near switch all is to be fixed on above the base, guide rail etc. of mobile device through support usually; Be fixedly connected with support near switch; In order to ensure clever lightness near switch, can not be too far away near the distance of switch and mobile object to be detected, guarantee in " detecting distance ".But, because the stability of main equipment operation can't guarantee that in running, can and bump near switch, directly damage is near switch.
Therefore, prior art still haves much room for improvement and develops.
The utility model content
The purpose of the utility model is to provide a kind of self-reacting device near switch, prevents saidly to be damaged by collision near switch.
The technical scheme of the utility model is following:
A kind of self-reacting device near switch; Wherein, Comprise holder and be arranged on the holder relatively-movable near Switch main body; Saidly comprise front end hold-down nut and rear end hold-down nut near Switch main body, said holder is between said front end hold-down nut and the rear end hold-down nut, between said front end hold-down nut and the said holder elastic buffer structure is set.
Described self-reacting device, wherein, said elastic construction is a spring.
Described self-reacting device, wherein, the internal diameter of said spring and said be matched in clearance near the Switch main body external diameter.
A kind of self-reacting device near switch that the utility model provided owing to elastic buffer structure is set said near switch, thereby has effectively prevented saidly to be damaged by collision near switch.
Description of drawings
Fig. 1 is the self-reacting device structural representation of the utility model near switch.
Fig. 2 is that the utility model is used sketch map near the self-reacting device of switch.
Embodiment
Below will combine accompanying drawing, the embodiment of the utility model is specified, described specific embodiment in order to explain the utility model, is not the embodiment that is used to limit the utility model only.
A kind of self-reacting device of the utility model near switch; Be mainly used in electric installing area; As shown in Figure 1; A kind of self-reacting device near switch comprise holder 105 and be arranged on the holder 105 near Switch main body 100, said holder 105 is L shaped, said holder 105 is fixed on base plate or the guide rail of equipment or the like.The aperture that said holder 105 is used to install said installing hole near Switch main body 100 is slightly larger than said external diameter near Switch main body 100, and the said relatively holder of promptly said Switch main body 100 can move forward and backward.Saidly comprise front end hold-down nut 101 and rear end hold-down nut 102 near Switch main body 100; Said holder 105 is between said front end hold-down nut 101 and the rear end hold-down nut 102; Said front end near Switch main body 100 also is provided with inductive head 104, and said inductive head 104 is used for displacement or speed of perception body to be detected etc.Between said front end hold-down nut 101 and said holder 105 near Switch main body 100, an elastic buffer structure is set; Said elastic buffer structure has two effects; The one, form buffering and also reset, the 2nd, utilize the tension force of elastic buffer structure to prevent saidly before and after receiving under the external force effect on said holder 105, not move near Switch main body 100.Said elastic buffer structure is preferably spring 103; Said spring 103 is set in said near on the Switch main body 100; The internal diameter of said spring 103 is slightly larger than said external diameter near Switch main body 100, guarantees that said spring 103 is said relatively movable near Switch main body 100.When body to be detected and said collides near Switch main body 100, under the pressure effect of body to be detected, said near moving behind the Switch main body 100; Said holder 105 is fixed, and the said spring 103 of front end hold-down nut 101 compressions this moment forms buffering; Said pressure is converted into the elastic force of said spring 103; After pressure disappeared, compressed spring 103 resiliences made saidly to reset near Switch main body 100.Thereby prevented effectively said near switch this 100 by the collision and damage.
The application of said self-reacting device near switch is as shown in Figure 2, is provided with a rotating shaft 200 in the gathering sill 201, saidly is used to detect the position of said rotating shaft 200 in said gathering sill 201 near Switch main body 100.Said rotating shaft 200 can do swinging along the center line of said gathering sill 201, when the amplitude of fluctuation of said rotating shaft 200 is excessive when work; Said rotating shaft 200 can collide said near Switch main body 100, and is under the pressure of said rotating shaft 200, said near moving behind the Switch main body 100; Said holder 105 is fixed, and the said spring of said front end hold-down nut 101 compressions this moment forms buffering; Said pressure converts the elastic force of said spring 103 into, after pressure disappears, and compressed spring 103 resiliences; Make saidly to reset near Switch main body 100, prevented effectively said near Switch main body 100 by said rotating shaft 200 collisions and damage.
Should be understood that; The preferred embodiment that the above is merely the utility model is not sufficient to limit the technical scheme of the utility model, concerning those of ordinary skills; Within the spirit and principle of the utility model; Can increase and decrease according to above-mentioned explanation, replacement, conversion or improvement, and all these increases and decreases, replacement, conversion or improve after technical scheme, all should belong to the protection range of the utility model accompanying claims.
