Abstract

The utility model relates to an up-holding down-pressing structure for a fixing sensor apparatus, which relates to the field of the connecting device. The fixing structure is composed of a sensor, a screwing screw, and a cap nut fixing element. The thread of the cap nut fixing element which is connected with the screwing screw is arranged on the platform of the sensor, and the lower end of the screwing screw is provided with a reverse hook portion which is embedded into the corresponding clamping opening of the sensor. When the screwing screw rotates downwardly, because of the barrier of the inner wall of the platform, the cap nut fixing element can move upwardly until reaching to the flange on the top of the cylinder groove; accordingly, the screwing screw is made to downwardly press the sensor; the sensor is made to be fixedly close to the bottom of the cylinder groove, and the sensing effect of the sensor can be improved. Simultaneously, since the screwing screw can only rotate in the through hole of the platform, so the sensor can not be damaged. The utility model has simple structure and favorable effect; the sensor can not be damaged, and the up-holding down-pressing structure for the fixing sensor apparatus can make the sensor act the function completely through being tightly fixed with the sensor.

Description

A kind of top depression sensor fixed structure of going up

Technical field:

The utility model relates to the coupling arrangement field, refers in particular to a kind of top depression sensor fixed structure of going up.

Background technique:

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

Summary of the invention:

The purpose of this utility model is to overcome the defective of prior art, provide a kind of simple in structure, not fragile sensor, and can reliably sensor and cylinder groove be fit together, make the respond well a kind of top depression sensor fixed structure of going up of sensor sensing.

For achieving the above object, the utility model is realized in the following way: be equipped with on the sensor be used in combination screw screw and fixed by nut part, the fixed by nut part is threaded and screws screw, and be positioned on the platform of sensor, the lower end that screws screw has a barb portion to embed in the corresponding bayonet socket of sensor.

Form one with one heart and connect the inner groovy of bayonet socket with bayonet socket on the platform of described sensor, inner groovy is ccontaining for the thread section lower end that screws screw.

The advantage of the utility model technology is simple in structure, screw just rotates in the through hole on sensor, not with the break-in of sensor plastics, so can not damage sensor, and during rotary screw, the fixed by nut part is top and the mutual screens in cylinder groove top upwards, impel screw screw with sensor to pressing down, and sensor and cylinder groove fit together fix firmly, thereby improve the inductive effects of sensor, be beneficial to and apply.

Embodiment:

See that shown in the accompanying drawing 2-7, the utility model includes sensor 1, be equipped with on the sensor 1 be used in combination screw screw 2 and fixed by nut part 3.Fixed by nut part 3 is threaded and screws screw 2, and is positioned on the platform 11 of sensor 1, and the lower end that screws screw 2 has a barb portion 21 to embed in the corresponding bayonet socket 12 of sensor 1.Form one coaxially with bayonet socket 12 on the platform 11 of sensor 1, and connect the inner groovy 13 of bayonet socket 12, inner groovy 13 is ccontaining for the thread section lower end that screws screw 2.

See accompanying drawing 8, shown in 9, sensor 1 is penetrated in the cylinder groove 04, utilize the hexagon wrench to insert and screw in the hexagon ring at screw 2 tops, clockwise direction screws screw 2, fixed by nut part 3 is followed rotary screw 2 rotations, but blocked by platform 11 inwalls of sensor 1 and can not rotate, because threaded connection relation, fixed by nut part 3 moves up gradually and pushes up the flange on cylinder groove 04 top until the flange of fixed by nut part 3, screw the thread section lower ends downward jam sensor 1 of screw 2 this moment, and sensor 1 is close to firmly is fixed on cylinder groove 04 bottom, thereby improved the inductive effects of sensor 1 greatly.If counterclockwise screw screw 2, can sensor 1 be got loose contrary operation.

So since screw screw 2 just the through hole inward turning on platform 11 change rather than can not damage sensor 1 with sensor 1 break-in.

Certainly, the embodiment of the above, be the preferred embodiments of the utility model only, be not to limit the utility model practical range, so all do variation or modification according to the described structure of the utility model claim, feature and principle all should be included in the utility model claim.
