Description

Sound level meter convenient to maintain

Technical Field

The utility model relates to the technical field of sound level meters, in particular to a sound level meter convenient to maintain.

Background

The sound level meter is the most basic noise measuring instrument, which is an electronic instrument, but is different from objective electronic instruments such as a voltmeter and the like. When the acoustic signal is converted into the electric signal, the time characteristic of the response speed of the human ear to the acoustic wave can be simulated; sound level meters have characteristics of different sensitivity and intensity characteristics that change characteristics at different loudness, and are subjective electronic instruments.

The wind shield needs to be sleeved on the sound level meter when the sound level meter is used, but the structure for fixing the wind shield is lacked on the sound level meter, so that the wind shield is easy to separate from the sound level meter, and the sound level meter needs to be correspondingly improved.

SUMMERY OF THE UTILITY MODEL

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a sound level meter convenient to maintain, includes the instrument body, install the connecting rod through the screw bolt on the lateral wall of instrument body, fixedly connected with ring piece on the connecting rod, the inboard fixedly connected with lug of ring piece, the tip cover of instrument body is equipped with the windshield, fixedly connected with arc piece on the connecting rod, the round hole has been seted up on the arc piece, it has the round bar to run through in the round hole, the one end fixedly connected with snap ring of round bar, other end fixedly connected with pull rod, set up the recess corresponding with the pull rod position on the connecting rod, be equipped with on the round bar to the spacing locating part of snap ring.

Preferably, the locating part includes the spring that the cover was established on the round bar, spring one end and the lateral wall welding of pull rod, the other end and the lateral wall welding of arc piece.

Preferably, the inner side of the snap ring is fixedly connected with an elastic rubber cushion block.

Preferably, the outer wall of the round rod is smooth and provided with a wear-resistant layer.

Preferably, the outer wall of the pull rod is provided with anti-skid grains.

In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that:

1. this application is established when the sound level meter upper end through the wind cap cover, and the bottom of wind cap can with the inboard fixed connection's of ring piece lug butt to restrict the position of wind cap, make the wind cap cover establish predetermined position, under the effect of spring, the snap ring can be close to the wind cap by oneself, thereby block the wind cap, make the wind cap can not break away from with the sound level meter easily, the use of sound level meter is more laborsaving.

2. This application can play the protection to the windshield through the inboard fixed connection's of snap ring cushion for the snap ring can not damage the windshield when will the windshield fixed, consequently the play effect that the windshield can be stable need not worry and damages, can give the better experience of user, and loaded down with trivial details step has been saved in the process of operation, and the connecting rod can be followed the sound level meter by oneself and torn down in addition, and is comparatively convenient.
