[0002] A drop-proof handheld laser 3D scanner for highway asset inventory is a high-precision measurement device that combines laser ranging technology and 3D scanning technology and is specifically designed for fast and accurate 3D data capture in highway asset management, maintenance and inventory work.
[0003] Traditional handheld laser 3D scanners often lack a convenient fixed rope length adjustment mechanism, which makes users face many inconveniences when using them in different environments. In addition, during the use of handheld laser 3D scanners, the device's anti-fall performance is directly related to its service life and safety. Traditional protection designs often cannot meet the use requirements in complex environments, especially in high-risk environments such as highway asset inspections. The device's anti-fall performance is particularly important.
[0004] Therefore, based on the above search and in combination with the prior art, a drop-proof handheld laser 3D scanner for highway asset inventory is proposed to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a drop-proof handheld laser 3D scanner for highway asset inventory to solve the problems raised in the above-mentioned background technology.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A drop-proof handheld laser 3D scanner for highway asset inventory comprises a base, a grip bar is fixedly mounted on the top surface of the base, a scanner body is fixedly mounted on the top surface of the grip bar, a fixing block is fixedly mounted on the front side wall of the grip bar, and a fixing rope is arranged on the side wall of the fixing block; an adjustment component and a protection component are arranged on the grip bar, the adjustment component is used to adjust the length of the fixing rope, and the protection component is used to protect the base, the grip bar and the scanner body.
[0008] Furthermore, the adjustment assembly includes: a rotating rod, which is rotatably connected to the inside of the grip, one end of the fixing rope is connected to the side wall of the fixing block, and the other end passes through the side wall of the grip and is connected to the outer surface of the rotating rod, the side wall of the grip is rotatably connected to a knob, and the side wall of the knob is connected to one side of the rotating rod.
[0009] Furthermore, the protective assembly includes: four outer rods, the four outer rods are respectively fixedly mounted on the two side walls of the handle, the insides of the four outer rods are all sleeved with inner sleeves, and a protective shell is fixedly mounted on the side walls of the two inner sleeves on the same side.
[0010] Furthermore, a circular cavity is opened inside the four outer rods, and a limit ring is fixedly installed at one end of the four inner sleeves located in the circular cavity. The limit ring slides on the circular cavity, and a spring is arranged inside the four circular cavities.
[0011] Furthermore, the inner diameter of the circular cavity is the same as the outer diameter of the spring.
[0012] Furthermore, the side wall of the knob and the side wall of the handle are provided with the same number of limiting holes, wherein the limiting holes are slidably connected with latches.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. By setting up an adjustment component, the length of the fixed rope can be conveniently adjusted. By rotating the knob, the rotating rod connected to it rotates synchronously, thereby changing the winding amount of the fixed rope on the rotating rod, and realizing the rapid adjustment of the length of the fixed rope. At the same time, the coordinated use of the limit hole and the latch allows the user to fix the knob at different positions according to actual needs, thereby fixing the length of the rope;
[0015] 2. The anti-fall performance of the handheld laser 3D scanner is significantly improved by providing a protective component. Specifically, the protective component includes four outer sleeves and matching inner sleeves, protective shells, limit rings, springs and other components, forming a comprehensive protection system. When the device falls accidentally, the protective shell first absorbs part of the impact force, effectively reducing the force directly acting on the device body. At the same time, the sliding of the inner sleeve in the outer sleeve and the squeezing of the spring by the limit ring further disperse and absorb the remaining impact force, thereby reducing the risk of equipment damage.

The fixing rope 5 is made of a breathable and soft material. The fixing rope 5 firmly connects the user's fingers with the equipment to prevent the equipment from falling due to the staff's hand slipping. An adjustment component and a protection component are arranged on the grip 2. The adjustment component is used to adjust the length of the fixing rope 5, and the protection component is used to protect the base 1, the grip 2 and the scanner body 3;
