[0030] Reference Figure 1 As shown, the utility model provides a technical solution: a real estate surveying and mapping offset frame, including a mounting seat 1, three rotating bars 2 are rotatably connected to the inner side of the mounting seat 1, a sliding bar 3 is slidably connected to the inside of the rotating bar 2, a cone block 4 is fixedly installed at the lower end of the sliding bar 3, a protective structure 5 is provided on the side wall of the sliding bar 3, and a winding structure 6 is provided on the side wall of the sliding bar 3.
[0031] The specific configuration and function of the protective structure 5 and the winding structure 6 will be described in detail below.
[0032] Reference Figure 1-Figure 4 As shown, in this embodiment: the protective structure 5 includes a connecting block 504 fixedly connected to the side wall of the slide bar 3, a rotating pin 505 is rotatably connected inside the connecting block 504, a sliding rod 501 is slidably connected inside the rotating pin 505, a limiting ring 509 is fixedly installed on the other end of the sliding rod 501, and a ball 510 is slidably connected inside the limiting ring 509. The provision of the ball 510 reduces the friction during the process of moving the real estate surveying and mapping offset frame, and can achieve the shielding of the cone block 4, thereby avoiding the situation where the cone block 4 scratches the ground. The side wall of the sliding rod 501 is fixedly connected with a stopper 502, and the surface of the sliding rod 501 is covered with a spring 503, and the two ends of the spring 503 are fixedly connected to the stopper 502 and the rotating pin 505 respectively. The stopper 502 will be lifted by the pulling force of the spring 503 on the rotating pin 505, which facilitates the normal use of the cone block 4.
[0033] The upper side of the slide bar 501 is rotatably connected with a rotating plate 506, and a slot 508 is provided on the side wall of the slide bar 3. The size of the rotating plate 506 matches the size of the slot 508. The rotating plate 506 at the upper end of the slide bar 501 is rotated and sleeved on the inner side of the slot 508 to support the slide bar 501. An elastic pad 507 is glued to the upper surface of the rotating plate 506, and a plurality of pits 511 are provided on the side wall of the ball 510. The setting of the elastic pad 507 increases the resistance of the rotating plate 506 to rotate out from the inner side of the slot 508. By setting the pit 511 on the ball 510, the ball 510 is prevented from being relatively smooth and easily idling with the ground, thereby improving the rolling stability of the ball 510.
[0034] Reference Figure 1-Figure 2 and Figure 5 As shown, specifically, the winding structure 6 includes a positioning block 64 fixedly connected to the side wall of the slider, and a limiting rope 61 is passed through the interior of the three positioning blocks 64. Pulling the limiting rope 61 inside the three positioning blocks 64 can realize the rapid contraction of the three rotating bars 2 and the sliding bar 3.
[0035] The end side of the limiting rope 61 is fixedly connected to the sphere 62, the other end of the limiting rope 61 is fixedly connected to an elastic rope 66, the other end of the elastic rope 66 is fixedly connected to a hook 67, and a reserved hole 63 is provided on the surface of the sphere 62. After the redundant limiting rope 61 is put away, the hook 67 on the elastic rope 66 is pulled, and the hook 67 is hooked on the inner side of the reserved hole 63 on the sphere 62, and the elastic rope 66 will shrink, so that the binding work between the three slide bars 501 can be realized. The side wall of the positioning block 64 is fixedly connected to two limiting strips 65, and the limiting strips 65 are a bent structure. The redundant limiting rope 61 can be wound around the position between two adjacent limiting strips 65. By setting the limiting strip 65 with a bent structure, it is convenient to quickly insert the limiting rope 61 between the two limiting strips 65.
[0036] Working principle: when moving the real estate surveying and mapping offset frame on some tiles or horizontal hard ground, first slide the sliding rod 501 inside the rotating pin 505, and after stretching the sliding rod 501 to a certain position, rotate the rotating pin 505 inside the connecting block 504, and rotate the ball 510 to the side facing the tip of the cone block 4. At this time, rotate the rotating plate 506 at the upper end of the sliding rod 501, and put the rotating plate 506 on the inner side of the card slot 508, so as to support the sliding rod 501 and avoid the shrinkage of the sliding rod 501 during use. The setting of the elastic pad 507 increases the resistance of the rotating plate 506 to rotate out from the inner side of the card slot 508, and improves the stability of the rotating plate 506 stuck in the inner side of the card slot 508. At this time, the real estate surveying and mapping offset frame can be moved on tiles or horizontal hard ground. The setting of the ball 510 reduces the friction in the process of moving the real estate surveying and mapping offset frame, and can block the cone block 4, thereby avoiding the cone block 4 scratching the ground, and can The swivel plate 506 on the inner side of the card slot 508 is rotated out, and then the slide bar 501 is rotated. At this time, the stopper 502 will be lifted up by the pulling force of the spring 503 on the rotating pin 505, which is convenient for the normal use of the cone block 4. By setting the pit 511 on the ball bearing 510, the situation that the ball bearing 510 is relatively smooth and easily idling with the ground is avoided, and the rolling stability of the ball bearing 510 is improved. By setting the protective structure 5, the flexible covering of the cone block 4 is facilitated, and the safety of the real estate surveying and mapping offset frame is improved. The ball bearing 510 is set to block the position of the cone block 4, which is convenient for the long-distance movement of the real estate surveying and mapping offset frame, and the situation that the cone block 4 will scratch the ground when the real estate surveying and mapping offset frame is moved over a long distance is avoided, which improves the performance of the real estate surveying and mapping offset frame to a certain extent.
[0037] When it is necessary to fold up the real estate surveying and mapping offset frame, the limiting rope 61 on the inner side of the three positioning blocks 64 can be pulled to realize the rapid contraction of the three turning bars 2 and the sliding bar 3. The excess limiting rope 61 can be wrapped around the position between two adjacent limiting bars 65. By setting the limiting bar 65 with a bending structure, it is convenient to quickly insert the limiting rope 61 between the two limiting bars 65. After the excess limiting rope 61 is folded up, pull the hook 67 on the elastic rope 66, and hook the hook 67 on the inner side of the reserved hole 63 on the sphere 62. The elastic rope 66 will shrink, thereby realizing the bundling work between the three sliding bars 501. By setting the sphere 62 and the hook 67, the situation where the limiting rope 61 slides out from the inner side of the positioning block 64 can also be avoided. By setting the winding structure 6, the binding and tightening work between the three sliding bars 3 is facilitated, and the folding of the real estate surveying and mapping offset frame after use is facilitated.
