Description

Technical Field

[0001] This utility model belongs to the technical field of safety protection devices for chemical operations, and more specifically, it relates to a safety protection device for chemical operations. Background Technology

[0002] In chemical operations, the design and use of safety protection devices are very important, as they can effectively reduce accidents and injuries caused by improper operation or environmental hazards. Among them, safety goggles can be used to protect the eyes from splashes of chemicals.

[0003] When workers are performing chemical operations, chemical substances splashed onto the lenses of protective goggles, or other dust and impurities adhered to the surface of the goggles, can blur the workers' vision and thus affect their work.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a safety protection device for chemical operations, in order to achieve a more practical value. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a safety protection device for chemical operations, which is achieved by the following specific technical means:

A tension spring is fitted around the movable rod, with its two ends connected to the pulling block and the opposite side of the mounting block, respectively. A movable block is connected to the bottom of the movable rod. Racks are provided on both sides of the movable block. A pair of rotating shafts are rotatably connected within the chamber near the movable block. Gears are installed around the rotating shafts. A mounting plate is installed at one end of each rotating shaft, penetrating one side of the goggle body. A connecting groove is provided on one side of the mounting plate, and a connecting block is movably connected within the connecting groove. A scraper is installed on one side of the connecting block.

[0007] Furthermore, the movable block is provided with a movable groove, and a limiting block is movably connected in the movable groove. A support rod is installed on the bottom end face of the limiting block, and the bottom end of the support rod passes through the bottom of the movable groove and connects to the bottom of the chamber.

[0008] Furthermore, one side of the mounting plate is provided with a through hole, and a bolt is movably connected in the through hole.

[0009] Further, one side of the connecting block is provided with a threaded groove, the position of the threaded groove corresponds to the position of the through hole, and the threads on the surface of the bolt are matched with the threads in the threaded groove.

[0010] Further, the pair of gears are located on both sides of the movable block, and the gears are intermeshed with the racks.

[0011] Further, the scraper is attached to the surface of the goggle body.

[0012] Further, the surface of the pulling block is provided with anti-skid texture.

[0013] Compared with the prior art, the utility model has the beneficial effects that:

[0014] When the lens surface of the goggle is attached with impurities, the staff moves the pulling block upward, the pulling block drives the movable block to move upward through the movable rod, the movable block drives the pair of racks to move upward, the racks are intermeshed with the gears, so that the racks drive the rotating shaft to rotate through the gears when moving upward, the rotating shaft drives the mounting plate to rotate, the mounting plate drives the scraper to rotate, the scraper can clean the impurities on the lens surface of the goggle through rotation, so as to facilitate the work of the staff, then the pulling block is loosened, at this time, the stretching spring drives the movable rod to move downward through the pulling block under the action force, so that the scraper returns to the initial position, avoiding that the scraper blocks the vision of the staff, thereby improving the practicability of the product.

[0015] When the scraper needs to be replaced, the staff starts to rotate the bolt, so that one end of the bolt is separated from the threaded groove, the scraper is taken out, then the connecting block on one side of the new scraper is inserted into the connecting groove on one side of the mounting plate, and the bolt is rotated in the opposite direction, so that one end of the bolt moves into the threaded groove and fixes the scraper, so that the effect of quickly replacing the scraper is realized, thereby improving the convenience of the product.
