The pull rope 38 is pulled so that the rangefinder body 1 can perform measurement operations. When the user accidentally lets go of the pull rope 38, the pull rope 38 loses its tension. In the process of the rangefinder body 1 falling to the ground, in the anti-fall device 3, the previously stretched tension spring 33 is quickly contracted to restore to the state before stretching. While the tension spring 33 is contracted, the tension spring 33 pulls the limit block 37 to move, and the limit block 37 sliding on the limit column 32 will drive the baffle 34 close to the fixing device 36, so that the baffle 34 is quickly moved to the outside of the transceiver port 2, so that the transceiver port 2 can be protected when the rangefinder falls.
[0018] The inner wall of the fixed frame 31 is fixedly connected to the two ends of the limit column 32, the side of the tension spring 33 away from the limit block 37 is fixedly connected to the inner wall of the fixed frame 31, the outer wall of the roller 39 is rotatably connected to the inner wall of the rangefinder body 1, the pull rope 38 is pulled, the pull rope 38 slides on the roller 39, and pulls the baffle 34 to move in the direction away from the fixing device 36. When the baffle 34 slides on the fixed frame 31, the tension spring 33 is stretched, and the transceiver port 2 is gradually exposed, so that the rangefinder body 1 can perform measurement operations.
[0019] The fixing device 36 includes a T-shaped plate 361, the outer wall of the T-shaped plate 361 is fixedly connected to a pressing plate 362, the bottom of the T-shaped plate 361 is fixedly connected to a compression spring 363, the bottom of the compression spring 363 is fixedly connected to a fixing plate 364, the outer wall of the fixing plate 364 is fixedly connected to the inner wall of the rangefinder body 1 through a sliding groove 6, and the sliding groove 6 is provided in the wall of the rangefinder body 1, the outer wall of the T-shaped plate 361 is slidably connected to the outer wall of the fixing frame 31, the moving baffle 34 carries the buckle 35 and hits the T-shaped plate 361, due to the inclined surface setting of the buckle 35 and Under the impact force of the baffle 34, the buckle 35 presses down the T-shaped plate 361 and fits it to the groove position of the fixed frame 31. Since the T-shaped plate 361 is pressed down, the pressed down T-shaped plate 361 and the fixed plate 364 squeeze the compression spring 363, and the compression spring 363 is restored to the uncompressed state, and the fixed plate 364 is fixed in the sliding groove 6, so that the compression spring 363 pushes the T-shaped plate 361 upward. At this time, the groove below the buckle 35 moves to the top of the T-shaped plate 361, and the lifted T-shaped plate 361 cooperates with the buckle 35, thereby fixing the position of the baffle 34.
[0020] The anti-scratch device 5 includes a bidirectional screw 53, the outer wall of the bidirectional screw 53 is threadedly connected to an upper movable frame 51, an upper receiving groove 52 is provided in the wall of the upper movable frame 51, a friction wheel 54 is fixedly connected to the outer wall of the bidirectional screw 53, a lower movable frame 55 is threadedly connected to the outer wall of the bidirectional screw 53, a lower receiving groove 56 is provided in the wall of the lower movable frame 55, both ends of the bidirectional screw 53 are rotatably connected to the inner wall of the rangefinder body 1 through a movable groove 7, and the movable groove 7 is provided in the wall of the rangefinder body 1, and the inner wall of the upper movable frame 51 and the lower movable frame 55 are connected to each other. The inner walls are slidably connected to the outer wall of the rangefinder body 1, and the friction wheel 54 is rotated, and the friction wheel 54 drives the bidirectional screw 53 to rotate. Due to the thread arrangement of the bidirectional screw 53 in the movable groove 7, the upper movable frame 51 and the lower movable frame 55 can approach and move away from each other under the control of the bidirectional screw 53. When carrying the rangefinder body 1, the upper movable frame 51 and the lower movable frame 55 are controlled to approach each other, and the fitted anti-scratch device 5 can protect the display screen 4 from being scratched, and the anti-scratch device 5 can be moved away and will not hinder the normal use of the rangefinder body 1.
[0021] Working principle:
[0022] When in use, the locking of the baffle 34 by the fixing device 36 is released and the pull rope 38 is pulled at the same time. The pull rope 38 slides on the roller 39 and pulls the baffle 34 to move away from the fixing device 36. When the baffle 34 slides on the fixing frame 31, the tension spring 33 is stretched and the transceiver port 2 is gradually exposed, so that the rangefinder body 1 can perform measurement operations. When the user accidentally lets go of the pull rope 38, the tension force is lost. In the process of the rangefinder body 1 falling to the ground, the previously stretched tension spring 33 in the anti-fall device 3 is quickly contracted to restore to the state before stretching. When the tension spring 33 contracts, the tension spring 33 pulls the limit block 37 to move. The limit block 37 sliding on the limit column 32 will drive the baffle 34 close to the fixing device 36. The fast-moving baffle 34 collides with the buckle 35 against the T-plate 361. Due to the inclined setting of the buckle 35 and the impact force of the baffle 34, the buckle 35 presses down the T-shaped plate 361 and fits it into the groove position of the fixed frame 31. As the T-shaped plate 361 is pressed down, the pressed T-shaped plate 361 and the fixed plate 364 squeeze the compression spring 363. The compression spring 363 is restored to the uncompressed state, and the fixed plate 364 is fixed in the sliding groove 6, so that the compression spring 363 pushes the T-shaped plate 361 upward. At this time, the groove below the buckle 35 moves to the top of the T-shaped plate 361, and the lifted T-shaped plate 361 cooperates with the buckle 35, thereby fixing the position of the baffle 34, preventing the baffle 34 from leaving the upper end of the transceiver port 2 due to the vibration caused by falling, causing the transceiver port 2 to be damaged. Pressing the pressing plate 362 downward to move can drive the T-shaped plate 361 to move, thereby releasing the fixation of the T-shaped plate 361 to the buckle 35.
[0023] The anti-scratch device 5 is provided, and the friction wheel 54 is rotated, and the friction wheel 54 drives the bidirectional screw 53 to rotate. Due to the thread arrangement of the bidirectional screw 53 in the movable groove 7, the upper movable frame 51 and the lower movable frame 55 can be close to each other and away from each other under the control of the bidirectional screw 53. When the rangefinder body 1 is carried, the upper movable frame 51 and the lower movable frame 55 are controlled to be close to each other. Since the thread pitch of the bidirectional screw 53 at the bottom of the friction wheel 54 is larger than that of the bidirectional screw 53 at the top of the friction wheel 54, the lower movable frame 55 is relatively The upper movable frame 51 moves faster, so that even if the lower movable frame 55 has a longer stroke than the upper movable frame 51, it can be synchronously attached to the outer wall of the friction wheel 54 with the upper movable frame 51. Since the upper storage groove 52 and the lower storage groove 56 are provided, when the upper movable frame 51 and the lower movable frame 55 are attached, the friction wheel 54 can also be exposed, which is convenient for adjusting the anti-scratch device 5. The attached anti-scratch device 5 can protect the display screen 4 from being scratched, and the anti-scratch device 5 can be movably removed and will not block the normal use of the rangefinder body 1.
