[0037] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0038] Embodiment one
[0039] Reference Figures 1-4The utility model provides a municipal housing construction surveying with the flagpole of convenient use, including frame 1, be provided with adjusting assembly 2 on frame 1, adjusting assembly 2 includes: pivot 211 is connected in the inside wall of frame 1 rotationally, gear 21 is fixedly connected on the outside of pivot 211, sliding slot 221 is symmetrically opened in the inside wall of frame 1, sliding block 22 is symmetrically and is connected in sliding slot 221 slidingly, left rack 23 is fixedly connected on the right side wall of left sliding block 22, left rack 23 is engaged with gear 21, right rack 24 is fixedly connected on the left side wall of right sliding block 22, right rack 24 is engaged with gear 21, upper column 25 is fixedly connected on the top of right rack 24, and upper column 25 top penetrates and extends to the top of frame 1, lower column 26 is fixedly connected on the bottom of left rack 23, and lower column 26 bottom penetrates and extends to the bottom of frame 1, support plate 261 is fixedly connected on the bottom of lower column 26, drive mechanism 27 is arranged on frame 1 with pivot 211, drive mechanism 27 includes: worm wheel 271 is fixedly connected on the outside of pivot 211, worm 272 is connected in the inside wall of frame 1 rotationally and is engaged with worm wheel 271, hand wheel 273 is connected in the right side wall of frame 1 rotationally, and hand wheel 273 is fixedly connected with the right end of worm 272, sliding block 22 is dovetail, and the shape of sliding slot 221 is adapted to sliding block 22.
[0040] In use, the staff carries the device to the construction site, the support plate 261 is in contact with the ground, and the hand wheel 273 in the drive mechanism 27 is rotated, the drive mechanism 27 drives the pivot 211 to rotate: when the staff rotates the hand wheel 273, the hand wheel 273 drives the worm 272 to rotate, the worm 272 drives the worm wheel 271 at the top to rotate, and the worm wheel 271 drives the gear 21 connected with the pivot 211 to rotate. When the rotating direction of the hand wheel 273 makes the gear 21 rotate counterclockwise, the left rack 23 and the right rack 24 on both sides of the gear 21 move simultaneously, the left rack 23 drives the lower column 26 at the bottom to extend out of the frame 1, the right rack 24 drives the upper column 25 at the top to extend out of the frame 1, and the combined length of the upper column 25 and the lower column 26 at both ends increases, thereby facilitating subsequent measurement. After the measurement is completed, the staff reversely rotates the hand wheel 273, the drive mechanism 27 drives the gear 21 to rotate clockwise, and the left rack 23 and the right rack 24 simultaneously drive the upper column 25 and the lower column 26 to retract into the frame 1, thereby reducing the volume of the device and facilitating subsequent carrying. When the left rack 23 and the right rack 24 move, the sliding blocks 22 connected thereto slide in the sliding slots 221, and the dovetail-shaped sliding blocks 22 make the sliding blocks 22 unable to separate from the sliding slots 221 when sliding in the sliding slots 221, thereby achieving the guiding effect of the movement of the left rack 23 and the right rack 24 and increasing the stability of the upper column 25 and the lower column 26 extending out of the frame 1.
[0041] The structure that the worm wheel 271 meshes with the worm 272 is prior art, when the worm 272 rotates, the helical surface of the worm 272 drives the gear of the worm wheel 271 to mesh and move, so that the worm 272 rotates along the axis perpendicular to the worm wheel 271. The rotating direction of the worm 272 determines the rotating direction of the worm wheel 271, changing the rotating direction of the worm 272 will also change the rotating direction of the worm wheel 271, so the worm 272 can drive the worm wheel 271 to rotate forward and backward.
[0042] For example, in some conveying equipment of automatic production line, the worm and gear reducer is used to control the running direction of the conveying belt, the worm is controlled to rotate forward and backward by the motor, so that the conveying belt advances and retreats.
[0043] Embodiment two
[0044] According to the basis of embodiment one, an auxiliary function is added.
[0045] Referring to Figures 1-4 The outer side wall of the upper column body 25 is fixedly connected with a pointer 3. The outer side wall of the lower column body 26 is symmetrically and fixedly connected with a supporting triangular block 262, and the bottom of the supporting triangular block 262 is fixedly connected with the top of the supporting plate 261. The top view cross-sectional area of the sliding groove 221 is equal to the top view cross-sectional area of the sliding block 22.
[0046] When the measured height of the house is high and has a recessed space, at this time the upper column body 25 is inconvenient to measure the recessed space, at this time the device can be rotated, so that the pointer 3 extends into the recessed space, at this time the height of the upper column body 25 is adjusted, and the pointer 3 replaces the upper column body 25 to contact the wall, so that the height of the space is conveniently obtained. The supporting triangular block 262 supports the circumferential side of the lower column body 26, thereby increasing the stability of the supporting plate 261 and the lower column body 26 when supporting. The equal cross-sectional areas of the sliding groove 221 and the sliding block 22 make the sliding block 22 unable to shake in the sliding groove 221 when the sliding block 22 moves in the sliding groove 221, thereby improving the stability when the left rack 23 and the right rack 24 subsequently move.
[0047] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
