Description

TECHNICAL FIELD

[0001] The application relates to the technical field of three-dimensional scanners, in particular to a protective device for a three-dimensional laser scanner used for engineering construction surveying. BACKGROUND

[0002] Three-dimensional laser scanning technology is a technology that can quickly reconstruct a three-dimensional model of a measured target and various drawing data such as lines, surfaces and bodies by recording the three-dimensional coordinates, reflectivity and texture of a large number of dense points on the surface of the measured object through the principle of laser ranging. Compared with traditional single-point measurement, three-dimensional laser scanning technology is also called a technical breakthrough from single-point measurement to area measurement because the three-dimensional laser scanning system can densely and massively obtain data points of a target object.

[0003] A hand-held three-dimensional scanner protective device is disclosed in the patent with the publication number CN221055728U. The three-dimensional laser scanner is usually placed in a box, and a damping device is placed in the box to prevent damage to the three-dimensional laser scanner during transportation. The box and the lid are hinged, so that when other objects are placed on the box, the other objects need to be removed before the lid can be opened, which is inconvenient.

[0006] In the above technical solution, the equipment to be protected is placed in the pull-out box, and the pull-out box can be removed from the box through the opening of the box. When other objects are stacked on the box, the equipment to be protected can be taken out without moving the other objects. The fixing assembly can keep the pull-out box in the box to prevent the pull-out box from sliding out of the box when the vehicle jolts.

[0007] Further, the buffer is a bubble film.

[0008] In the above technical solution, the posture of the bubble film can be changed flexibly. Workers can fold the bubble film according to the shape of the equipment to be protected. The bubble film can buffer the equipment to be protected and reduce the possibility of damage caused by impact.

[0009] Further, the fixing assembly comprises a spring embedded in the inner wall of the box and a limiting block mounted at the end of the spring and in sliding connection with the box, the sliding direction of the limiting block being perpendicular to the sliding direction of the pull-out box, one end of the pull-out box at the opening thereof being provided with a limiting slot for embedding the limiting block, the limiting block being able to always protrude out of the outer wall of the box, and the spring being able to force the limiting block to be embedded in the limiting slot so as to keep the pull-out box in the box.

[0010] In the above technical solution, the spring can force the limiting block to be embedded in the limiting slot, at this time, the limiting block and the limiting slot have a limiting effect on the pull-out box, thereby preventing the pull-out box from being pulled out of the box when the vehicle is jolted, and the limiting block can be pulled by hand to make the limiting block disengage from the limiting slot, at this time, the pull-out box can be directly pulled out of the box by hand.

[0011] Further, a sponge pad is mounted on the inner wall of the box, and the sponge pad can contact the protected equipment in the pull-out box.

[0012] In the above technical solution, the sponge pad can contact the upper surface of the protected equipment, thereby further protecting the protected equipment.

[0013] Further, a plurality of rollers are arranged on the outer wall of the box, and the box is in sliding connection with a pull-out rod, and the box can be dragged by the pull-out rod by hand.

[0014] In the above technical solution, when the protected equipment is heavy, the pull-out rod can be pulled out, and the box can be dragged by the pull-out rod, which is more labor-saving.

[0015] Further, two backpack straps are arranged on the box.

[0016] In the above technical solution, the worker can carry the box by using the backpack straps.

[0017] Further, a dust shield is arranged on the box, the dust shield is mounted on the outer wall of the box where the backpack straps are arranged, and the dust shield can separate the body clothes from the rollers.

[0018] In the above technical solution, when the worker carries the box, the dirt on the rollers may adhere to the body clothes, and the dust shield can separate the body from the rollers, thereby reducing the possibility of the dirt adhering to the clothes.

[0019] Further, a rubber pad is arranged on the inner wall of the box and located at the opening of the box, and the rubber pad can contact the pull-out box.

[0020] In the above technical solution, when the pull-out box is located in the box, the rubber pad can abut against the pull-out box, thereby reducing the possibility of the humid moisture from the outside entering the pull-out box.

[0021] In summary, the application has the following technical effects: the device to be protected is placed in the drawer box, the drawer box can be separated from the box through the opening of the box, when other objects are stacked on the box, the device to be protected can be taken out without moving other objects, the fixing assembly can keep the drawer box in the box at all times to prevent the drawer box from sliding out of the box when the vehicle jolts.
