DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 7As shown, a three-dimensional scanner with dustproof function includes a three-dimensional scanning device 1; a dustproof mechanism is provided at the front end of the three-dimensional scanning device 1;

[0026] The dustproof mechanism includes a side baffle 21, which is arranged at a position near both sides of the front end of the three-dimensional scanning device 1, and both sides of the bottom end of the side baffle 21 are rotatably connected to the connecting seat 22, and the connecting seat 22 is fixedly connected to the front end of the three-dimensional scanning device 1. The rear side of the side baffle 21 is glued with a first sealing ring 23, and the first sealing ring 23 is made of rubber. The top of the side baffle 21 is fixedly connected to a first fixing block 24, and a notch 25 is opened on the first fixing block 24, and the notch 25 and the second fixing block 26 are connected. The rear end of the second fixing block 26 is fixedly connected to the slider 27, the slider 27 is sleeved on the outside of the slide rail 28, the slide rail 28 is fixedly connected to the inside of the slide groove 29, the slide groove 29 is opened at the front end of the three-dimensional scanning device 1, the outside of the slide rail 28 is wound with a spring 30, and a second dustproof component is arranged at the center of the front end of the three-dimensional scanning device 1; the two sides of the spring 30 are respectively fixedly connected to the two groups of sliders 27; the front end of the second fixing block 26 is provided with an inclined surface, and the second fixing block 26 is designed in a hook shape;

[0027] During operation, when it is necessary to release the obstruction of the lens by the side baffle 21, first push the two groups of second fixing blocks 26 closer to each other, so that the second fixing blocks 26 release the state of engagement between the notches 25, and when the second fixing blocks 26 move, the slider 27 fixedly connected to the second fixing blocks 26 moves synchronously inside the slide groove 29, so that the two groups of slide grooves 29 synchronously squeeze the spring 30, so that the spring 30 produces elastic deformation under the action of the squeezing force, and at this time, the side baffle 21 is rotated to release the obstruction of the lens of the three-dimensional scanning device 1 by the side baffle 21, and when the lenses on both sides of 02 are not needed, the side baffle 21 is rotated in the opposite direction to make the grooves 29 move. The two sides of the inner wall of the slot 25 squeeze the inclined surface on the second fixing block 26. At this time, the second fixing block 26 moves under the action of the squeezing force. When the connecting seat 22 is in contact with the front end of the three-dimensional scanning device 1, the second fixing block 26 passes through the slot 25. At this time, the squeezing force of the inner wall of the slot 25 on the second fixing block 26 disappears. The second fixing block 26 returns to its original position under the action of the restoring force of the spring 30, and engages with the slot 25 to fix the side baffle 21, so that the connecting seat 22 is tightly fitted with the front end of the three-dimensional scanning device 1, thereby protecting and dustproofing the lenses on both sides of the three-dimensional scanning device 1.

[0028] Further, the second dustproof component includes a front baffle 31, a positioning block 33 is glued to the rear side of the front baffle 31, and the positioning block 33 is made of rubber. The rear end of the front baffle 31 is fixedly connected with a positioning block 33 near the two sides, and the positioning block 33 is inserted into the inside of a positioning seat 34. The positioning seat 34 is fixedly connected to the two sides of the inner wall of the front end of the three-dimensional scanning device 1. A card block 36 is glued to the inner wall of the positioning seat 34, and the card block 36 is made of rubber. The card block 36 is engaged with a card slot 37, and the card slot 37 is provided on the positioning block 33;

[0029] During operation, when the front baffle 31 is to be installed, the positioning block 33 is first aligned with the positioning seat 34, and then the positioning block 33 is inserted into the interior of the positioning seat 34. When the positioning block 33 is inserted into the interior of the positioning seat 34, one side of the positioning block 33 squeezes the rubber block 36 glued to the inner wall of the positioning seat 34, causing the block 36 to produce elastic deformation. When the positioning block 33 is completely inserted into the interior of the positioning seat 34, the squeezing force of the positioning block 33 on the block 36 disappears. At this time, the block 36 returns to its original state under the action of its own restoring force and engages with the card slot 37, thereby fixing the front baffle 31 and making the second sealing ring 32 fit tightly with the front end of the three-dimensional scanning device 1, thereby achieving a dust-proof effect.

[0030] Furthermore, the front baffle 31 is fixedly connected with a pulling plate 38 at the position near both sides of the front end, and the two sets of pulling plates 38 are provided with an inclined surface on the side away from each other, and the two sets of pulling plates 38 are glued with an anti-slip strip 39 on the side away from each other, and the anti-slip strip 39 is made of rubber;

[0031] During operation, when the front baffle 31 needs to be removed, the two sets of pulling plates 38 can be pinched by hand at the same time and pulled in the direction away from the three-dimensional scanning device 1 to remove the front baffle 31. The anti-slip strip 39 made of rubber material can increase the friction force to avoid the front baffle 31 slipping when being pulled.

[0032] Furthermore, the positioning block 33 is made of cast iron, and the positioning block 33 is attracted to the magnet 35, and the magnet 35 is fixedly connected to the inner wall of the positioning seat 34;

[0033] During operation, when the positioning block 33 is completely inserted into the positioning seat 34 , the positioning block 33 and the magnet 35 are attracted to each other, thereby playing an auxiliary fixing effect on the front baffle 31 .

[0034] Working principle: when the side baffle 21 is to be released from blocking the lens, first push the two groups of second fixing blocks 26 closer to each other, so that the second fixing blocks 26 release the state of being engaged between the notches 25, and when the second fixing blocks 26 move, the slider 27 fixedly connected to the second fixing blocks 26 moves synchronously inside the slide groove 29, so that the two groups of slide grooves 29 synchronously squeeze the spring 30, so that the spring 30 produces elastic deformation under the action of the squeezing force, and at this time, the side baffle 21 is rotated to release the blocking of the lens of the three-dimensional scanning device 1 by the side baffle 21, and when the lenses on both sides of 02 are not needed, the side baffle 21 is rotated in the opposite direction. The two sides of the inner wall of the notch 25 squeeze the inclined surface on the second fixing block 26. At this time, the second fixing block 26 moves under the action of the squeezing force. When the connecting seat 22 is in contact with the front end of the three-dimensional scanning device 1, the second fixing block 26 passes through the notch 25. At this time, the squeezing force of the inner wall of the notch 25 on the second fixing block 26 disappears. The second fixing block 26 returns to its original position under the action of the restoring force of the spring 30, and engages with the notch 25 to fix the side baffle 21, so that the connecting seat 22 is tightly fitted with the front end of the three-dimensional scanning device 1, thereby protecting and dustproofing the lenses on both sides of the three-dimensional scanning device 1.

[0035] When the front baffle plate 31 is to be installed, the positioning block 33 is first aligned with the positioning seat 34, and then the positioning block 33 is inserted into the interior of the positioning seat 34. When the positioning block 33 is inserted into the interior of the positioning seat 34, one side of the positioning block 33 squeezes the rubber block 36 glued to the inner wall of the positioning seat 34, causing the block 36 to elastically deform. When the positioning block 33 is fully inserted into the interior of the positioning seat 34, the squeezing force of the positioning block 33 on the block 36 disappears. At this time, the block 36 returns to its original state under the action of its own restoring force and engages with the card groove 37, thereby fixing the front baffle plate 31 and making the second sealing ring 32 fit tightly with the front end of the three-dimensional scanning device 1, thereby achieving a dust-proof effect. When the front baffle plate 31 is to be removed, the two sets of pulling plates 38 are pinched by hand at the same time and pulled in the direction away from the three-dimensional scanning device 1 to remove the front baffle plate 31.

[0036] When the positioning block 33 is completely inserted into the positioning seat 34 , the positioning block 33 and the magnet 35 are attracted to each other, thereby playing an auxiliary fixing effect on the front baffle 31 .

[0037] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
