Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

Referring to fig. 1-4, a leak detection apparatus in the drawings includes a detector body 1, a protective cover 2, and a buffer structure 6, wherein the protective cover 2 is located outside the detector body 1 and used for protecting the detector body 1, a first opening 3 for air to enter is provided at the bottom of the protective cover 2, a second opening 4 is provided at the top of the protective cover 2, a sealing cover 5 is provided outside the second opening 4, and the buffer structure 6 is located in the protective cover 2 and used for providing a certain buffer between the protective cover 2 and the detector body 1.

The buffer structure 6 includes buffer block 7, and buffer block 7 is equipped with the counterpoint, evenly fixes at the inboard bottom of protective sheath 2, and protective sheath 2 side evenly is equipped with buffer hole 8.

The outside of the second opening 4 is uniformly provided with embedded columns 9, and the sealing cover 5 is provided with embedded holes 10 for the embedded columns 9 to pass through.

A limiting block 11 is fixed at the top of the embedded column 9.

The detector body 1 is embedded in the protective sleeve 2, at the moment, the air inlet at the rear side of the detector body 1 coincides with the first opening 3, outside air can enter the detector body 1 to carry out concentration detection, the second opening 4 can be sealed by embedding the sealing cover 5 on the embedded column 9, the numerical value displayed on the control interface of the detector body 1 can be observed because the protective sleeve 2 is transparent, when the detector body falls accidentally, the protective sleeve 2 forms primary protection, the buffer block 7 is secondary protection, and damage to the detector body 1 caused by falling is reduced.

Example 2

Referring to fig. 1 and 2, this embodiment further describes example 1: the utility model provides a leak detection device, includes detector body 1, protective sheath 2 and buffer structure 6, and protective sheath 2 is located the detector body 1 outside for protect detector body 1, protective sheath 2 bottom is equipped with the first opening 3 that is used for the air to get into, and the protective sheath 2 top is equipped with second opening 4, and the second opening 4 outside is equipped with closing cap 5, and buffer structure 6 is located protective sheath 2 for provide certain buffering between protective sheath 2 and detector body 1.

Both the protective sleeve 2 and the sealing cover 5 are made of latex materials.
