Description

Technical Field

[0001] This utility model relates to a scanning device, specifically a portable scanning device, and belongs to the field of scanning device technology. Background Technology

[0002] A scanner is a device that uses a large amount of X-ray absorption data obtained when scanning around an object to reconstruct its tomographic image. The data it collects is often used for three-dimensional reconstruction calculations to create digital models of real objects in the virtual world. When outdoor scanning is required, it is often necessary to carry the equipment with you. Traditional equipment is relatively fixed and extremely inconvenient.

[0003] According to patent CN218494620U, a portable 3D scanning device is disclosed, including a 3D scanning device body. A fixed base is fixedly connected to the lower end of the 3D scanning device body. Four rectangular slots are opened inside the mounting plate. Springs are fixedly connected to the rectangular slots on the side away from each other. Slide plates are fixedly connected to the four springs on the side close to each other.

[0004] The above solution allows for the disassembly of the mounting plate and support rod as needed during implementation, facilitating storage and portability. However, it is difficult to protect the scanner lens during implementation. The scanner lens is usually exposed to the external environment and contains multiple precision optical components. If it comes into contact with other objects during transport, it may cause damage to the lens, affecting the normal use of the scanner. Therefore, we provide a portable scanning device to solve the above problems. Utility Model Content

[0009] Preferably, the inner wall of the protective cover has two snap-fit ​​grooves, and the two snap-fit ​​posts are slidably connected to the two corresponding snap-fit ​​grooves respectively. When the snap-fit ​​posts are snapped into the snap-fit ​​grooves, they can limit the movement of the protective plate.

[0010] Preferably, a return spring is sleeved on the outer surface of each sliding rod, and a connecting block is slidably connected to the outer surface of each sliding rod. The return spring can push the locking post to reset, thereby keeping the locking post locked with the locking groove.

[0011] Preferably, the two ends of the return spring are fixedly connected to the snap-fit ​​post and the connecting block, respectively. The connecting block is fixedly connected to the protective cover and provides support for the sliding of the sliding rod.

[0012] Preferably, a control plate is provided on the outside of the two protective covers. The control plate is fixedly connected to two sliding rods, and a pull strap is fixedly connected to the outer surface of the control plate. The pull strap makes it easy for the user to pull the control plate.

[0013] Preferably, a plug-in plate is fixedly connected to the outer surface of the protective plate, a magnetic suction hole is opened inside the protective plate, and a magnetic block is fixedly connected to the outer surface of the protective cover.

[0026] This utility model provides a portable scanning device.

[0027] Please see Figure 1 The device includes a handheld 3D scanner 1. A shoulder strap 10 is fixedly connected to the outer surface of the handheld 3D scanner 1. The shoulder strap 10 is made of cotton and linen cloth, which makes it easy for staff to carry the scanning device. When the staff uses the device for scanning, they can also wrap the shoulder strap 10 around their wrist to secure the device and prevent the user from slipping and damaging the device during the scanning process, thus improving the safety of the device.

[0028] Both ends of the handheld 3D scanner 1 are fixedly equipped with scanning lenses 2. The handheld 3D scanner 1 and scanning lenses 2 involved in this application are both prior art, and will not be described in detail in this application.

[0029] Please see Figure 1 , Figure 2 and Figure 3 Each scanning lens 2 has a protective cover 3 fixedly connected to its outer surface. The protective cover 3 can shield the scanning lens 2 to a certain extent, reducing the occurrence of dust and other floating objects falling on the scanning lens 2. The protective cover 3 can also protect the scanning lens 2 and reduce the probability of damage to the scanning lens 2.

[0030] Please see Figure 2 , Figure 3 and Figure 4 The protective cover 3 has a slot 5 inside, and a protective plate 6 is slidably connected inside the slot 5. Through the setting of the slot 5 and the protective plate 6, multiple optical elements on the surface of the scanning lens 2 can be shielded and protected, so as to prevent the scanning lens 2 from colliding with other objects during the carrying process and causing damage to the components on the scanning lens 2, thus protecting the normal use of the equipment.

[0031] The outer surface of the protective plate 6 is fixedly connected to the plug plate 7. The user can pull the protective plate 6 out of the slot 5 through the plug plate 7 to facilitate the subsequent use of this scanning equipment. When the equipment is not in use, the staff can plug the protective plate 6 back into the slot 5 through the plug plate 7 so that the protective plate 6 can continuously protect the scanning lens 2.

[0032] The protective plate 6 has a magnetic suction hole 8 inside, and a magnetic block 9 is fixedly connected to the outer surface of the protective cover 3. The magnetic suction hole 8 and the magnetic block 9 are compatible. When the operator uses the device, the protective plate 6 is pulled out from the slot 5 through the plug plate 7, and then the protective plate 6 is inserted into the magnetic block 9. The magnetic suction hole 8 and the magnetic block 9 have a certain magnetic attraction effect, which can keep the protective plate 6 stable on the magnetic block 9 and prevent the operator from randomly placing the protective plate 6 after pulling it out, which would cause the protective plate 6 to be lost.

[0033] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Each protective cover 3 is equipped with a limiting mechanism 4 inside. The limiting mechanism 4 includes two sliding rods 401 that are slidably connected to the protective cover 3. By setting the two sliding rods 401, the limiting effect of the locking post 402 on the protective plate 6 can be increased, and the protective plate 6 is prevented from falling out of the slot 5 during the locking process with the slot 5, thus affecting the protective effect of the protective plate 6 on the scanning lens 2.

[0034] A control plate 405 is provided on the outside of the two protective covers 3. The control plate 405 is fixedly connected to the two sliding rods 401. A pull strap 406 is fixedly connected to the outer surface of the control plate 405. The operator can pull the control plate 405 by pulling the pull strap 406. The movement of the control plate 405 can drive the two sliding rods 401 to slide inside the protective cover 3, thereby canceling the snap-fit ​​effect between the snap-fit ​​post 402 and the snap-fit ​​groove, making it convenient for the operator to insert the protective plate 6 into the snap-fit ​​groove 5 or pull the protective plate 6 out of the snap-fit ​​groove 5.

[0035] Each sliding rod 401 has a fixed connection to a snap-fit ​​post 402 at one end. The inner wall of the protective cover 3 has two snap-fit ​​grooves. The two snap-fit ​​posts 402 are slidably connected to the two corresponding snap-fit ​​grooves respectively. When the snap-fit ​​post 402 snaps into the snap-fit ​​groove, the snap-fit ​​post 402 will limit the protective plate 6, so that the protective plate 6 and the snap-fit ​​groove 5 maintain a relatively stable state, and prevent the protective plate 6 from sliding out of the snap-fit ​​groove 5 on its own due to shaking during the carrying process.

[0036] Each sliding rod 401 has a return spring 403 fitted on its outer surface, and a connecting block 404 is slidably connected to the outer surface of each sliding rod 401. The connecting block 404 is fixedly connected to the protective cover 3. The two ends of the return spring 403 are fixedly connected to the locking post 402 and the connecting block 404, respectively. The connecting block 404 provides support for the sliding of the sliding rod 401, so that the sliding rod 401 remains stable during the sliding process. The elastic potential energy of the return spring 403 is sufficient to push the locking post 402 to maintain the locking state with the locking groove. The return spring 403 will wobble slightly due to its own properties. This wobble is within the acceptable range of the device and will not affect the locking of the locking post 402.

[0037] Working principle: When staff need to carry the scanning equipment for outdoor scanning, they first pull the pull belt 406. The pull belt 406, under force, moves the control plate 405. The control plate 405 pulls the sliding rod 401 to slide inside the protective cover 3. The sliding rod 401 slides and pulls the locking post 402 to slide, thereby canceling the locking effect between the locking post 402 and the locking slot. Then, the staff holds the plug plate 7 and inserts the protective plate 6 into the locking slot 5. Then, they release the pull belt 406. At this time, the locking post 402 will re-lock into the locking slot under the push of the return spring 403. This keeps the protective plate 6 in a state of shielding and protecting the scanning lens 2, preventing the scanning lens 2 from being damaged by contact with other objects during carrying and improving the service life of the equipment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
