DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-5 , a handheld scanning device for inputting BIM models, comprising a scanning head 1, a data receiver 2, and a connecting line 3, wherein the connecting line 3 is connected to the scanning head 1 and the data receiver 2, wherein the scanning head 1 is movably mounted on one side of the data receiver 2, and a wire bin 6 is fixedly mounted on the other side of the data receiver 2, wherein the wire bin 6 is a hollow cylindrical structure with one side open, a rotating structure is provided on the side of the wire bin 6 away from the data receiver 2, a through hole is provided on the side of the wire bin 6 close to the data receiver 2, the connecting line 3 passes through the wire bin 6 from the through hole, and a wire management structure is provided at the opening of the wire bin 6;

[0024] The rotating structure includes a gear block 13, on which a rotating tube 14 is fixedly mounted. The rotating tube 14 penetrates the cavity of the wire bin 6 and is rotatably connected to the inner wall of the wire bin 6.

[0025] The wire management structure includes a plastic roller 18, a wire management groove 17 is provided on the plastic roller 18, the connecting wire 3 is movably installed in the wire management groove 17, a limit shaft 20 is fixedly installed on the wire bin 6, a torsion spring 19 is fixedly sleeved on the limit shaft 20, and the outer side of the torsion spring 19 is fixedly installed on the plastic roller 18. The stability of the connecting wire 3 when entering and exiting the wire bin 6 is achieved by setting the wire management groove 17, and the connecting wire 3 is prevented from being entangled and affecting normal use. The torsion spring 19 is set to achieve automatic locking. When the wire is pulled quickly, the plastic roller 18 rotates, driving the wire management groove 17 to rotate and stop the wire from coming out, thereby preventing the wire from falling out quickly due to the scanner being out of hand, thereby protecting the safety of the scanner;

[0026] The gear block 13 is provided with a limiting structure, which includes a fixed block 7, which is fixedly mounted on the outer wall of the line bin 6, and a limiting groove 8 is penetrated through the center of the fixed block 7, and a connecting column 9 is movably installed in the limiting groove 8, and a toothed block 10 is fixedly mounted on one end of the connecting column 9, and the block 10 is meshed with the gear block 13.

[0027] like Figure 3 As shown, one end of the connecting column 9 away from the block 10 is fixedly installed with a limiting circular block 12, and a compression spring 11 is movably sleeved on the connecting column 9, one end of the compression spring 11 is fixedly installed on the block 10, and the other end is fixedly installed on the limiting circular block 12, the limiting circular block 12 is in contact with the fixed block 7, and the limiting groove 8 limits the movement of the connecting column 9, and the connecting column 9 can only slide on the limiting groove 8. Through the setting of the compression spring 11, when the limiting circular block 12 is released, the block 10 is driven to mesh with the gear block 13 under the resetting action of the compression spring 11, thereby fixing and limiting the movement of the gear block 13, and through the setting of the limiting circular block 12, the connecting column 9 is prevented from detaching from the fixed block 7 when sliding.

[0028] When the scanner is working, lift the limit circle 12, which drives the connecting column 9 to lift, and the connecting column 9 drives the card block 10 to lift. When the card block 10 is separated from the gear block 13, rotate the gear block 13, and when the gear block 13 rotates, it drives the rotating tube 14 to rotate. At the same time, pull the connecting line 3. When it is pulled to a suitable length, remove the scanning head 1 from the handle mounting slot 5 to perform scanning and recording.

[0029] like Figure 4 As shown, an inlet hole 16 and an outlet hole 15 are respectively provided at both ends of the rotating tube 14, wherein the inlet hole 16 is arranged close to the gear block 13, and the outlet hole 15 is arranged close to the data receiver 2. The connecting wire 3 passes through the inlet hole 16 and is wound around the rotating tube 14, and passes through the outlet hole 15 to be connected to the scanning head 1. The setting of the inlet hole 16 and the outlet hole 15 facilitates the connection between the connecting wire 3 and the data receiver 2, and prevents the connecting wire 3 from being detached from the rotating tube 14 during rotation. The connecting wire 3 passes through the outlet hole 15 and is wound around the rotating tube 14, and then passes through the inlet hole 16, passes through the wire management structure at the opening of the wire bin 6, and is connected to the scanning head 1.

[0030] like Figure 1-2 As shown, a support base 4 is provided on the data receiver 2, a handle mounting groove 5 is opened in the middle of the support base 4, and the handle of the scanning head 1 is movably installed in the handle mounting groove 5. The support base 4 and the handle mounting groove 5 cooperate with each other, which facilitates the carrying and use of the equipment.

[0031] The gear block 13, the rotating tube 14 and the wire bin 6 are arranged cocentrically.

[0032] The limiting axis 20 is parallel to the rotating tube 14 , and the limiting axis 20 is vertically arranged to the direction in which the connecting line 3 appears.

[0033] The side of the data receiver 2 is also provided with a card slot, and the card slot and the line bin 6 are arranged on the same side.

[0034] Working principle of the present invention:

[0035] When the scanner is working, lift the limit round block 12, and the limit round block 12 is lifted up to drive the connecting column 9 to be lifted up, and the connecting column 9 is lifted up to drive the card block 10 to be lifted up. When the card block 10 is separated from the gear block 13, the gear block 13 is rotated, and the gear block 13 drives the rotating tube 14 to rotate when it rotates, and at the same time pull the connecting line 3. When it is pulled to a suitable length, remove the scanner from the handle mounting groove 5 to perform scanning and input work. In this process, the support seat 4 and the handle mounting groove 5 cooperate with each other to facilitate the carrying and use of the equipment. The limit groove 8 limits the movement of the connecting column 9, and the connecting column 9 can only slide on the limit groove 8. Through the setting of the compression spring 11, when the limit round block 12 is released, the card block 1 is driven under the reset action of the compression spring 11. 0 is meshed with the gear block 13, thereby fixing the structure. The setting of the limiting round block 12 prevents the connection column 9 from being separated from the fixed block 7 when sliding. The setting of the wire inlet hole 16 and the wire outlet hole 15 facilitates the connection between the connecting wire 3 and the data receiver 2, and prevents the connecting wire 3 from being separated from the rotating tube 14 during rotation and passing through the wire management groove 17. The setting of the wire management groove 17 achieves the stability of the connecting wire 3 when entering and exiting the wire bin 6, and prevents the connecting wire 3 from being entangled and affecting normal use. The setting of the torsion spring 19 realizes automatic locking. When the wire is pulled quickly, the plastic roller 18 rotates, driving the wire management groove 17 to rotate and stop the wire from coming out, thereby preventing the wire from falling off quickly due to the scanner being out of hand, thereby protecting the safety of the scanner.
