[0025] Please refer to Figures 1 to 13 The present application provides a technical solution: a portable high-precision laser obstacle clearing instrument, comprising an integrated box 1 for accommodating the laser 4, further comprising: Two box covers 2 are installed at the opening of the integrated box 1, and the box cover 2 has two operating states: State one: two box covers 2 are respectively rotated with two side corner positions as the axis, and are opened or closed in a relative rotating manner; State two: two box covers 2 slide horizontally to the middle from the two side corner positions, and two box covers 2 are rotated with the middle contact position as the axis, so that the contact positions of two box covers 2 are in a clamped angle and form a support platform for installing the laser 4.

[0026] When the laser obstacle clearing instrument is used, the laser, power module, control system, beam focusing device and sensing feedback system and other components can be accommodated and placed in the integrated box 1, so as to facilitate carrying. Moreover, the box cover 2 is designed to have two operating states, state one (i.e. storage state), the box cover 2 is opened by rotating from the middle in a double-door form, so as to facilitate taking out or putting in the internal equipment; And state two (i.e. working state), after the laser 4 is taken out from the box cover 2, the two box covers 2 are closed, then the two box covers 2 are rotated with the middle contact position as the axis, and the two side corner positions are collected to the middle, so that the two box covers 2 are in a clamped angle in the middle, and a support platform for installing the laser 4 is formed, then the laser 4 is installed on the support platform to complete the support and fixation of the laser 4. For details, please refer to Figure 12That is, the state of the laser 4 when it is working, and because of the triangular support formed between the two box covers 2 and the integrated box 1, the support for the laser 4 is more stable, thereby improving the efficiency of laser clearing obstacles; In this way, through the dual-mode design of the box cover 2, the support platform for the laser 4 can be quickly deformed, completely eliminating the separate carrying and assembly steps of the traditional tripod, realizing the deployment mode of "out-of-box use", enhancing the reliability of the equipment, and significantly improving the portability, operation efficiency and safety of the equipment.

[0027] In one of the more preferred embodiments, an implementation of the installation of the box cover 2 is provided; The inner walls of the two sides of the integrated box 1 are provided with gradually lengthening grooves 11, the two side end positions of the gradually lengthening grooves 11 are provided with pin holes 12, the inside of the box cover 2 near the corner is provided with shaft holes 5, and two rotating shafts 6 that can be adjusted to approach or move away from each other are installed in the shaft holes 5, the opposite ends of the two rotating shafts 6 are provided with elastic rods 10, and the elastic rods 10 are inserted into the corresponding pin holes 12.

[0028] For details, please refer to Figure 6 and Figure 9 , in state one, the elastic rod 10 at the end of the rotating shaft 6 is inserted into the pin hole 12 near the edge position of the integrated box 1, at this time the box cover 2 can be opened or closed by rotating in a double-door manner, the elastic rod 10 can be seen in the enlarged part of Figure 5 , in which the inner end of the elastic rod 10 is connected to the outer end of the rotating shaft 6 through a telescopic spring, realizing the axial extension and contraction of the elastic rod 10; And in state two, the two rotating shafts 6 are adjusted to approach each other through external structure control, so that the outer end of the elastic rod 10 is withdrawn into the gradually lengthening groove 11, providing limiting and preparation for the sliding of the rotating shaft 6 on the box cover 2, and when the two box covers 2 are rotated and form a triangular support, the outer end of the elastic rod 10 will slide along the gradually lengthening groove 11 and be embedded into the pin hole 12 near the inner side, thereby providing limiting and support for the corner position of the box cover 2, so that it can maintain the triangular support state in Figure 12 ; For details, please refer to Figure 6 , the gradually lengthening groove 11 between the two pin holes 12 gradually becomes shallower from the outside to the inside, so that when the elastic rod 10 slides along the inner wall, it will first contract, and then pop out and be inserted into the inner side when it moves to the position of the inner pin hole 12, completing the limitation of its position.

[0029] In one of the more preferred embodiments, an implementation that can connect or not connect the contact position of the box cover 2 and an implementation of the support platform are provided; For details, please refer to Figure 3 , Figure 9 , Figure 12The contact surface of the two box covers 2 is provided with an arc-shaped cavity 13; Referring to Figure 10 In each box cover 2, a second sleeve 24 is fixed at the corner on one side of the arc-shaped cavity 13, and a carrier plate 21 is integrally formed at the bottom of the box cover 2, and a first sleeve 22 is fixed at the end of the carrier plate 21, and the first sleeve 22 is coaxial with the second sleeve 24, and a sleeve shaft 16 is arranged in the first sleeve 22 and the second sleeve 24, an arc-shaped strip 14 is arranged in the arc-shaped cavity 13, an intermediate sleeve 15 is formed at the corner of the arc-shaped strip 14, the intermediate sleeve 15 is sleeved on the sleeve shaft 16, and the intermediate sleeve 15 is connected with the sleeve shaft 16 through a flat key sliding connection, and a spring 23 is arranged between the convex ring on the outer wall of the intermediate sleeve 15 and the first sleeve 22; Referring to Figure 11 The opposite ends of the sleeve shafts 16 on the two box covers 2 are designed as complementary half cylinders; Referring to Figure 1 、 Figure 13 A through hole is formed in the top of the box cover 2 and penetrates the second sleeve 24, and an abutting rod 25 is arranged in the through hole and moves along the axial direction through threads for adjustment.

[0030] Referring to Figures 7-10 In state one, since the box cover 2 can be opened from the middle, when the two box covers 2 are in the closed state, the arc-shaped strip 14 is located in the arc-shaped cavity 13, and the carrier plate 21 supports the arc-shaped strip 14, and the intermediate sleeve 15 on the arc-shaped strip 14 is supported by the sleeve shaft 16, and the arc-shaped strip 14 can rotate around the axis of the sleeve shaft 16; Referring to Figure 8 and Figure 9 The structures of the two box covers 2 and the arc-shaped strip 14 are designed as central symmetry, so that when the two box covers 2 are closed, the intermediate sleeve 15 and the two sleeve shafts 16 are in the coaxial state, so that the two box covers 2 can rotate around the sleeve shaft 16 by connecting and locking the two sleeve shafts 16, and when the two sleeve shafts 16 do not contact each other, the two box covers 2 can be opened mutually / independently without affecting each other, so the connection of the two sleeve shafts 16 is the key; Therefore, in this embodiment, when the two sleeve shafts 16 need to be locked, the abutting rod 25 is rotated to move along the axial direction through threads for adjustment, as shown in Figure 13 , so that the front end of the abutting rod 25 abuts against the outer end of the ball head of the sleeve shaft 16 and moves transversely / axially, so that the half cylinders at the opposite ends of the two sleeve shafts 16 cross and are respectively inserted into the first sleeve 22 of the other box cover 2, and since the two arc-shaped strips 14 contact each other, the two sleeve shafts 16 can be locked; In this way, when the two covers 2 are relatively rotated, the two covers 2 can rotate around the sleeves 16 as the axis, and due to the mutual locking of the two sleeves 16 and the flat key connection between the sleeves 16 and the intermediate sleeve 15, the two mutually locked arc-shaped strips 14 can be rotated out of the arc-shaped cavities 13 along with the rotation of the covers 2, thereby forming a support platform for the subsequent assembly of the laser 4.

[0031] Conversely, when the two covers 2 are restored to the state shown in the figure, the abutting rod 25 is reversely rotated to be separated from the sleeve 16, and the sleeve 16 is reset under the elastic force of the spring 23, so that the two sleeves 16 are separated from each other and are unlocked, and are restored to the state of not affecting each other. Figure 1 Conversely, when the two covers 2 are restored to the state shown in the figure, the abutting rod 25 is reversely rotated to be separated from the sleeve 16, and the sleeve 16 is reset under the elastic force of the spring 23, so that the two sleeves 16 are separated from each other and are unlocked, and are restored to the state of not affecting each other.

[0032] In one of the more preferred embodiments, a mounting strip 18 is provided, which can be mounted on the two arc-shaped strips 14 after being locked; The mounting strip 18 is provided with an arc-shaped surface on the bottom surface, and the laser 4 is mounted on the top of the mounting strip 18. The two side walls of the arc-shaped strips 14 are provided with limiting arc-shaped grooves 20, and the mounting strip 18 is provided with limiting pins 19 which can be inserted into the limiting arc-shaped grooves 20 to limit the mounting strip 18.

[0033] Specifically, refer to Figure 7 and Figure 8 When the two arc-shaped strips 14 are locked and rotated out of the arc-shaped cavities 13, the mounting strip 18 is attached to the arc-shaped surface of the arc-shaped strips 14, and the limiting pins 19 are inserted into the limiting arc-shaped grooves 20, and then the mounting strip 18 is locked by means of bolts or the like, so as to complete the installation of the laser 4; Moreover, the mounting strip 18 can be rotated to adjust the angle of the laser 4 along the arc-shaped surface of the arc-shaped strips 14. In one of the more preferred embodiments, a mounting strip 18 is provided, which can be mounted on the two arc-shaped strips 14 after being locked; The two arc-shaped strips 14 are provided with worm gears 17 on the arc-shaped surfaces of the two arc-shaped strips 14, and the two worm gears 17 can be spliced with each other. The mounting strip 18 is provided with a worm 26 which can be rotated.

[0034] Refer to Figure 7 and Figure 8When the two arc-shaped strips 14 are attached and locked together, the two worm gear teeth 17 on them will be spliced ​​together to form a semi-circular worm gear tooth. Then, when the mounting strip 18 is attached to the arc-shaped strip 14, the worm 26 at its bottom will mesh with the worm gear tooth 17. In this way, when the servo motor at the bottom of the mounting strip 18 controls the worm 26 to rotate, the meshing action between the worm 26 and the worm gear tooth 17 can drive the mounting strip 18 to adjust its angle. The limiting pin 19 can play the role of sliding limit, while ensuring that the mounting strip 18 and the arc-shaped strip 14 remain in a close contact state.

[0035] In one preferred embodiment, the sidewall of the arc-shaped cavity 13 is provided with an arc-shaped groove, and the sidewall of the arc-shaped strip 14 is fixed with a sliding pin 27 that is slidably installed in the arc-shaped groove.

[0036] As can be seen from the above, after the two arc-shaped strips 14 are locked together, they will rotate out of the arc-shaped cavity 13 as the lid 2 rotates. To prevent the two arc-shaped strips 14 from rotating out of the arc-shaped cavity 13 at different angles, i.e., the arc-shaped strips 14 deviating towards one of the arc-shaped cavities 13, the limiting between the arc-shaped groove and the sliding pin 27 ensures that when the lid 2 rotates to the minimum included angle, the arc-shaped strips 14 are in their outermost state, and the sliding pin 27 also slides to the end of the arc-shaped groove. This ensures that the two arc-shaped strips 14 rotate out of the arc-shaped cavity 13 at the same angle, until a... Figure 12 The state shown in the image.

[0037] In one preferred embodiment, magnets 28 that can attract each other are installed on the contact surfaces of the carrier plate 21 and the arc strip 14.

[0038] As can be seen from the above, when the two arc-shaped strips 14 are in an unlocked state, the attraction between the carrier plate 21 and the arc-shaped strips 14 by the magnet 28 can stabilize the arc-shaped strips 14 within the arc-shaped cavity 13, thereby preventing them from rotating freely when the lid 2 is opened. For details of the magnet 28, please refer to [link / reference needed]. Figure 8 and Figure 9 .

[0039] In one preferred embodiment, an implementation is provided that can drive two rotating shafts 6 to move relative to or away from each other for adjustment; The top of the cover 2 has a through hole that communicates with the shaft hole 5, and a hand-tightening rod 7 is rotatably installed in the through hole. An adjusting block 8 is threadedly connected to the middle outer wall of the hand-tightening rod 7. A connecting rod 9 is rotatably connected to the end of the adjusting block 8 opposite to the two rotating shafts 6.

[0040] See Figure 5 By rotating the hand lever 7, the adjusting block 8 is moved through the threaded transmission, which in turn drives the rotating shaft 6 to move relative to or opposite to each other through the connecting rod 9, thereby achieving the purpose of changing the position of the rotating point of the box cover 2.

[0041] In one of the more preferred embodiments, the inner part of the integrated box 1 is also provided with a partitioning module 3, and the partitioning module 3 is provided with embedding slots for embedding the mounting strip 18 and the laser 4, as shown in Figure 3 The partitioning module 3 can facilitate the embedding of the laser 4 and the mounting strip 18, so as to prevent them from shaking during carrying.

[0042] The technical features of the above embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, but it should be understood that any combination of the technical features, as long as there is no contradiction, is within the scope of the present disclosure.

[0043] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these are within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
