DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0025] The utility model proposes a protective mechanism for a paint sanding machine, comprising a housing 1 and a paint sanding machine body 2, wherein the paint sanding machine body 2 is arranged on the upper end surface of the housing 1 and is fixedly mounted on the upper end surface of the housing 1 and can be relatively fixed, and further comprising;

[0026] A pair of protective vertical plates 3 are provided on the upper end surface of the shell 1 and are located on both sides of the paint sanding machine body 2;

[0027] The lower end surface of the protective vertical plate 3 is fixedly connected to the upper end surface of the shell 1, so that the protective vertical plate 3 and the shell 1 can be fixed to each other, so that the pair of protective vertical plates 3 protect both sides of the paint sanding machine body 2. At the same time, a first opening is formed in one of the protective vertical plates 3, which can facilitate the staff to collect the paint processed by the paint sanding machine body 2;

[0028] The protective horizontal plate 4 is provided between the clothing protective vertical plates 3 and is located above the paint sanding machine body 2;

[0029] The two ends of the protective horizontal plate 4 are respectively fixedly connected to the end surfaces of a pair of protective vertical plates 3 close to each other, which can protect the upper part of the paint sanding machine body 2;

[0030] A pair of sliding protective plates 5 are provided above the housing 1 and are slidably connected to a pair of protective vertical plates 3 respectively;

[0031] A pair of sliding protection plates 5 can protect the other two sides of the paint sanding machine body 2. At the same time, a second opening is formed in one of the sliding protection plates 5, which can facilitate the staff to operate the control panel on the paint sanding machine body 2;

[0032] The driving mechanism is disposed in the housing 1 and is used to drive the sliding protection plate 5 to move.

[0033] Specifically, the driving mechanism includes:

[0034] Two pairs of threaded rods 6, one end of each of which is rotatably connected to the inner lower end surface of the housing 1, and the other end of each of which passes through the upper wall of the housing 1;

[0035] Two pairs of thread grooves 7 are formed in the lower end surfaces of a pair of sliding protection plates 5 and are respectively threadedly connected to the two pairs of threaded rods 6;

[0036] The worm gear 8 is provided in the housing 1 and fixedly mounted on the outer surface of the threaded rod 6;

[0037] A pair of worms 9 are rotatably mounted in the housing 1 , and the pair of worms 9 are respectively meshed with the pair of worm wheels 8 ;

[0038] A pair of drive motors are fixedly installed on one side wall of the shell 1, and the output ends of the pair of drive motors are fixedly connected to one end of a pair of worm gears 9 respectively. The output ends of the pair of drive motors rotate forward or reversely, which can drive the pair of worm gears 9 to rotate. The rotation of the pair of worm gears 9 can drive the two pairs of worm gears 8 to rotate. At this time, the rotation of the two pairs of worm gears 8 can drive the two pairs of threaded rods 6 to rotate. At this time, under the action of the two pairs of threaded grooves 7, the rotation of the two pairs of threaded rods 6 can make the pair of sliding protective plates 5 rise or fall. At this time, the rise of the pair of sliding protective plates 5 can facilitate the staff to inspect and repair the paint sander body 2, and when they fall, they can protect the paint sander body 2 to prevent external factors from causing damage to the paint sander body 2.

[0039] Specifically, a pair of slide grooves 10 are formed on the upper end surfaces of the pair of protective vertical plates 3;

[0040] A pair of fixed blocks 11 are fixedly mounted on the end surfaces of the pair of sliding protection plates 5 that are close to each other, and a sliding rod 12 that is slidably connected to the sliding groove 10 is fixedly mounted on the lower end surface of the fixed block 11;

[0041] When the sliding protection plate 5 is raised or lowered, it can drive the pair of slide bars 12 to slide in the pair of slide grooves 10, so that the sliding protection plate 5 can remain stable when it is raised or lowered.

[0042] Specifically, a limiting groove 13 is formed on the inner wall surface of the slide 10, and a limiting block 14 is fixedly mounted on the outer surface of the slide rod 12 and is slidably connected to the limiting groove 13;

[0043] Under the action of the limiting groove 13 and the limiting block 14 , the sliding rod 12 can be prevented from separating from the sliding groove 10 .

[0044] Working principle: When the paint sander body 2 needs to be protected, the staff first starts a pair of drive motors. The output ends of the pair of drive motors rotate, which can drive the pair of worms 9 to rotate. The rotation of the pair of worms 9 can drive the two pairs of worm gears 8 to rotate. At this time, the rotation of the two pairs of worm gears 8 can drive the two pairs of threaded rods 6 to rotate. At this time, under the action of the two pairs of threaded grooves 7, the rotation of the two pairs of threaded rods 6 can make the pair of sliding protective plates 5 drop. At the same time, when the pair of sliding protective plates 5 drop, the two pairs of sliding rods 12 can slide into the two pairs of slide grooves 10, so that the pair of sliding protective plates 5 can remain stable when they drop, which can protect the paint sander body 2 and prevent external factors from causing damage to the paint sander body 2. Conversely, when the output ends of the pair of drive motors rotate in the opposite direction, the pair of sliding protective plates 5 can be raised, so that the paint sander body 2 can be exposed, making it convenient for the staff to use or repair the paint sander body 2, bringing convenience to people.
