Description

A kind of fixed sturcture of sensor

Technical field:

The utility model relates to the stationary installation technical field of sensor, refers in particular to a kind of fixed sturcture of sensor.

Background technology:

As accompanying drawing 1, the present employed sensor fixed sturcture of people, mainly be that screw 02 directly is screwed in the plastics thread through hole on the sensor 03, again screw 02 is screwed down until the bottom of pushing up cylinder 01 groove, thereby sensor 03 is moved up, push up the groove top of cylinder 01 and be fixed until sensor 03 upper end.This fixed form is owing to be break-in between the plastics thread of screw 02 and sensor 03, be easy to damage the plastics thread of sensor 03, and this mode is that sensor 03 is suspended from the groove upper end, so sensor 03 and cylinder 01 contact effect and fixed effect is all bad, thereby cause sensor 03 inductive effects not good.

As accompanying drawing 2, other plants present employed sensor fixed sturcture, is to utilize the lower end that screws screw 04 to have a barb to suppress in the corresponding bayonet socket that embeds sensor 03 front end, because of narrow and small, the fragile structure of front-end architecture volume of sensor 03; Very easy because of being pressed into when screwing screw 04, with the structural failure of bayonet socket.And when using, also be very easy to structural failure with bayonet socket, make sensor 03 can't fix and damage.

The utility model content:

The purpose of this utility model is exactly the weak point that exists at prior art and a kind of fixed sturcture of sensor is provided, and it has overcome existing sensor shortcoming of damage sensor easily fixedly the time, has advantage simple in structure, easy to make, that practicality is good.

To achieve these goals, the technical solution adopted in the utility model is: it comprises the platform that sensor front end is shaped, and platform offers a cavity near the lower surface, and the platform upper surface offers through hole, and through hole communicates with cavity; Cavity is combined with a slide block, and slide block can slide in this cavity, and shoe surface offers cam hole, and this cam hole front end is narrower, broadens gradually backward; In addition, embedding in through hole has nut, and nut is combined with bolt.

The head of described bolt offers the hexagonal counterbore, and the end of bolt is coniform, and its tapering cooperates with cam hole.

The side end face of slide block is provided with the oblique angle, this oblique angle be arranged on the narrow end of cam hole towards the side end face.

After adopting said structure, earlier slide block is put in the cavity of platform, make a end outside with oblique angle, guarantee that simultaneously cam hole communicates with through hole, then bolt is screwed in the nut, along with down moving, the rotating bolt of bolt begins to touch cam hole, because the cam hole front end is narrower, the rear end broad, and the end of bolt is coniform, the end of bolt touched the front end of cam hole before this, along with bolt down, the end of bolt and the contact area of cam hole are increasing, because bolt is limited in the nut and can not moves forward and backward, for the end that satisfies bolt can fully contact with cam hole, slide block can only move forward, and makes bolt fully to contact with cam hole.Along with going deep into of bolt, the beveled end of slide block will slowly be stretched out cavity outside, with corresponding groove clamping, and the most at last platform constraints in a certain position.So the utlity model has advantage simple in structure, easy to make, that practicality is good.

Embodiment:

See shown in Fig. 3-8 that the utility model comprises the platform 1 that sensor front end is shaped, platform 1 offers a cavity 2 near the lower surface, and platform 1 upper surface offers through hole 3, and through hole 3 communicates with cavity 2; Cavity 2 is combined with a slide block 4, and slide block 4 can slide in this cavity 2, and slide block 4 surfaces offer cam hole 5, and these cam hole 5 front ends are narrower, broaden gradually backward; In addition, embedding in through hole 3 has nut 6, and nut 6 is combined with bolt 7.

The head of described bolt 7 is offered hexagonal counterbore 71, and the end of bolt 7 is coniform, and its tapering cooperates with cam hole 5.

The side end face of slide block 4 is provided with oblique angle 8, this oblique angle 8 be arranged on cam hole 5 narrow ends towards the side end face, when the oblique angle 8 of slide block 4 during with corresponding groove clamping, groove can produce a downward extruding force to slide block 4, can make that like this platform 1 is adjacent to the device that is in contact with it.

Shown in the accompanying drawing 9-11 is that the utility model combined sensor 9 is applied to the use synoptic diagram on the cylinder 10:

Sensor 9 front ends form a platform 1, earlier slide block 4 is put into the cavity 2 of platform 1, then sensor 9 is penetrated in the groove of cylinder 10, sensor 9 forms a step 11 in the other end of cavity 2 openings, step 11 just with cylinder 10 groove clampings, at this moment utilize hex wrench that bolt 7 is screwed in the nut 6 again, along with down moving, the rotating bolt 7 of bolt 7 begins to touch cam hole 5, because cam hole 5 front ends are narrower, the rear end broad, and the end of bolt 7 is coniform, the end of bolt 7 touched the front end of cam hole 5 before this, along with bolt 7 down, the contact area of the end of bolt 7 and cam hole 5 is increasing, can not move forward and backward because bolt 7 is limited in the nut 6, for the end that satisfies bolt 7 can fully contact with cam hole 5, slide block 4 can only move forward, and makes bolt 7 fully to contact with cam hole 5.Along with going deep into of bolt 7, the beveled end of slide block 4 will slowly be stretched out cavity 2 outsides, last and cylinder 10 these groove clampings simultaneously, and sensor 9 is fixed in the groove of cylinder 10 the most at last.Adopt this fixed form, can make sensor 9 be close to the bottom that is fixed on cylinder 10, thereby improved the inductive effects of sensor 9.If unclamp sensor 9, with bolt 7 as stated above retrograde rotation get final product.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and are included in the utility model claim.
