[0002] In construction engineering construction, lofting refers to the process of placing the dimensions and positions on the design drawings onto the actual ground at the site. To accurately carry out lofting, distance measuring devices such as total stations, electronic theodolites or distance measuring laser instruments are usually required. These devices can help construction workers quickly and accurately measure parameters such as the length, width and height of the ground to ensure that each part of the building is correctly placed and positioned according to the design requirements. Distance measuring devices play an important role in construction engineering construction and can improve work efficiency and construction quality.

[0003] The existing distance measuring devices for construction engineering construction lofting have the following disadvantages during use:

[0004] Generally, the bottom end of a total station is fixed and supported by a support platform, and the bottom end of the support platform is supported by a collapsible tripod. However, there is no corresponding structure for protecting the total station when not in use on the support platform. Even if there is a structure, it is manually opened by workers, lacking a structure that can be linked to open the protective cover when the tripod is unfolded, resulting in great inconvenience during use. Therefore, a distance measuring device for construction engineering construction lofting is needed. Content of the Utility Model

Detailed implementation manner

[0019] The following further describes the present utility model in conjunction with embodiments.

[0020] In order to make the purposes, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present utility model in conjunction with the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The following embodiments are used to illustrate the present utility model, but cannot be used to limit the protection scope of the present utility model. The conditions in the embodiments can be further adjusted according to specific conditions. Any simple improvement of the method of the present utility model under the premise of the concept of the present utility model belongs to the protection scope required by the present utility model.

[0022] Embodiment

[0023] Generally, the bottom end of a total station is fixedly supported by a support platform 1, and the bottom end of the support platform 1 is supported by a foldable tripod. However, there is no corresponding structure on the support platform 1 to protect the total station when it is not in use. Even if there is such a structure, the protective cover 41 is manually opened, lacking a structure that can be linked to open the protective cover 41 when the tripod is unfolded, resulting in great inconvenience during use;

[0024] Therefore, please refer to Figures 1 - 3 , the present utility model provides a distance measuring device for construction engineering construction lofting, including: a support platform 1 and a total station main body 2 fixedly connected to the top end of the support platform 1. The bottom end of the support platform 1 is hinged with a plurality of support tripods 3 arranged in a circular array. The inner sides of the plurality of support tripods 3 are all hinged with push-pull rods 31, and the other ends of the push-pull rods 31 are all hinged to the outside of the same movable block 32. The movable block 32 is movably sleeved on the outside of the inverted T-shaped rod 33, and the top end of the inverted T-shaped rod 33 is fixedly connected to the top end of the support platform 1;

[0025] It further includes a linkage protection structure 4, which is installed on the movable block 32 and connected to the support platform 1.

[0026] Furthermore, as shown in Figures 1 - 3As shown, it is worth specifically noting that the number of support legs 3 is three.

[0027] The number of support legs 3 is set to three to facilitate the arrangement of the U-shaped rod 46 and the connecting rod 47, creating space and preventing the redundant support legs 3 from obstructing the design of these two structures.

[0028] Furthermore, as Figures 1 - 3 shown, it is worth specifically noting that in order to enable the unfolding or closing of the protective structure to be linked with the expansion or folding of the three support legs 3, a linkage-type protective structure 4 is provided, including a guiding channel 43 opened at a position near the rear sidewall at the top of the support platform 1. The vertical cross-section of the guiding channel 43 is of a convex structure. Two symmetrically arranged guiding bars 42 slide in the guiding channel 43. The vertical cross-sections of the guiding bars 42 are both of a convex structure. The tops of the guiding bars 42 are fixedly connected with protective covers 41. Openings a are provided on the opposite sidewalls of the two protective covers 41. Openings b are provided at the bottoms of the two protective covers 41. Transmission grooves 44 are provided on the backs of the two protective covers 41. Transmission columns 45 are movably lapped in the transmission grooves 44. One end of the two transmission columns 45 away from the transmission grooves 44 is fixedly connected with the same U-shaped rod 46. One sidewall of the U-shaped rod 46 facing the movable block 32 is fixedly connected with the movable block 32 through a connecting rod 47. The same threaded channel is provided on the U-shaped rod 46 and the connecting rod 47. A hand-tightening screw 48 is threadedly connected in the threaded channel. The end of the hand-tightening screw 48 movably penetrates through the movable block 32, and the end of the hand-tightening screw 48 after being tightened will press against the outside of the inverted T-shaped rod 33.

[0029] The inner height of the protective cover 41 is larger than the overall height of the total station main body 2, and the inner width of the protective cover 41 is larger than the width of the total station main body 2. The protective cover 41 can be made of transparent acrylic board material. The shape of the transmission groove 44 starts from a vertical groove at the top, then extends downward obliquely to form an angle, and terminates at another vertical groove at the bottom. The two transmission grooves 44 are symmetrically arranged. The width of the transmission groove 44 is equal to the diameter of the transmission column 45.

[0030] In summary, when using the distance measuring device for construction engineering construction lofting, when the total station main body 2 is not in use, by loosening the hand-tightened screw 48, the movable block 32 is not fixed on the inverted T-shaped rod 33. At this time, manually close the three support foot brackets 3, and then under the action of the three push-pull rods 31, the movable block 32 moves up and down on the inverted T-shaped rod 33, and drives the two transmission columns 45 connected by the connecting rod 47 and the U-shaped rod 46 to move down. With the shape design of the transmission groove 44, the two protective covers 41 can move relatively and merge through the guide strips 42 at the bottom ends respectively, so that it is convenient to close and cover the total station main body 2 when not in use for protection, realizing the linkage between the protection structure and the opening or closing of the three support foot brackets 3, and greatly improving the convenience of the user when using the distance measuring device.
