Description

Technical Field

[0001] The utility model relates to the technical field of positioning devices, in particular to a laser rapid positioning device without laying out a line. Background Art

[0002] Laying out lines is a construction method that facilitates the work of workers. The markings of the design drawings can be projected into the construction site, and construction can be carried out according to the markings later. Generally speaking, all building axes can be called large lines, and the corresponding small lines are the edge lines and dimension lines of the structural components.

[0003] Traditional line laying is a physical ink line, which requires construction workers to actually draw the line on the construction site. With the use of lasers, laser line laying can be done in real time without actually drawing the line. The current laser positioning device is used independently. When multiple groups of lasers are used in combination, the horizontal state of each group of lasers needs to be adjusted one by one, which is inconvenient to use. Therefore, a laser rapid positioning device without line laying is proposed. Utility Model Content

[0023] The above and other technical features and advantages of the utility model are further described below in conjunction with the accompanying drawings and embodiments. However, the following embodiments are only preferred embodiments of the utility model, not all of them.

[0024] Example:

[0025] like Figure 1-Figure 4 As shown, the utility model provides a laser rapid positioning device without laying out a line, comprising a main structure plate 1, a laser slide groove 2 is provided in the middle of the main structure plate 1, a multi-directional laser 3 and a plurality of groups of unidirectional lasers 4 are arranged inside the laser slide groove 2, storage chambers 5 are provided at the sides of both ends of the main structure plate 1, support components 6 are arranged inside the storage chambers 5, a group of first level gauges 7 are provided at both ends of the main structure plate 1, and a group of second level gauges 8 are arranged in the middle of the main structure plate 1;

[0026] The four groups of support components 6 cooperate to support the main structure plate 1 , and the first level 7 and the second level 8 cooperate to determine the setting level of the main structure plate 1 .

[0027] The surface of the main structure plate 1 is provided with scale marks, and the middle of the multi-directional laser 3 and the unidirectional laser 4 are provided with reference lines for alignment with the scale marks. When positioning, the multi-directional laser 3 and the unidirectional laser 4 can determine their own positions by the coordination of the reference lines and the scale marks, so as to facilitate precise alignment and installation.

[0028] The storage chamber 5 includes a storage groove 51 and a connecting shaft 52;

[0029] The storage groove 51 is opened at the end side of the main structure plate 1, and the connecting shaft 52 is installed at one end of the storage groove 51. The support assembly 6 is installed inside the storage groove 51 through the connecting shaft 52. The connecting shaft 52 is the rotation axis of the support assembly 6;

[0030] When the support assembly 6 is rotated out from the interior of the storage chamber 5 and unfolded, the support assembly 6 rotates with the connecting shaft 52 as the rotation axis, and the other end of the support assembly 6 moves out from the interior of the storage groove 51. The four groups of support assemblies 6 after unfolding cooperate with each other to support the main structure plate 1. With the support of the support assembly 6, the main structure plate 1 is stably set at the placement position.

[0031] The support assembly 6 includes a support rod 61, a threaded hole 62 and an adjustment rod 63;

[0032] One end of the support rod 61 is sleeved on the outside of the connecting shaft 52, and a threaded hole 62 is opened at the other end of the support rod 61. The adjusting rod 63 is threadedly connected to the threaded hole 62. The inner wall surface of the support rod 61 and the outer wall surface of the connecting shaft 52 are both ground. A limited connection structure is formed between the support rod 61 and the connecting shaft 52 through friction. Under the action of friction, there is a rotational resistance between the support rod 61 and the connecting shaft 52. When the support rod 61 is rotated and expanded with the connecting shaft 52 as the axis under the action of external force, the friction between the support rod 61 and the connecting shaft 52 can make the relative position between the support rod 61 and the connecting shaft 52 remain fixed, and there will be no retraction or reverse rotation, so as to ensure the stability of the support rod 61 supporting the main structure plate 1.

[0033] A hexagonal hole is provided at the end of the adjusting rod 63, and the bottom end of the adjusting rod 63 is of conical design. After the support rod 61 is fully unfolded, the adjusting rod 63 can be rotated by a hexagonal wrench, so that the adjusting rod 63 can adjust the setting position of the adjusting rod 63 in the threaded hole 62 through the threaded connection with the threaded hole 62. After extending from the inside of the threaded hole 62, the adjusting rod 63 can replace the support rod 61 to contact the ground, so as to adjust the setting height of the support rod 61, so as to overcome the problem of uneven ground. During the adjustment process, the horizontal state of the main structure plate 1 is judged by the cooperation of the first level meter 7 and the second level meter 8, and each group of adjusting rods 63 is adjusted in turn until the main structure plate 1 is adjusted to a horizontal state under the support of the adjusting rods 63.

[0034] The top of the adjusting rod 63 is glued with a limiting rubber ring 64, the edge of the limiting rubber ring 64 is rounded, and a gap for the limiting rubber ring 64 to be set is left between the top of the supporting rod 61 and the inner wall of the receiving groove 51, and the total length of the adjusting rod 63 and the limiting rubber ring 64 is less than the length of the threaded hole 62;

[0035] Before the support rod 61 is retracted into the interior of the storage groove 51, the adjusting rod 63 is rotated with a hexagonal wrench, and the adjusting rod 63 is retracted into the threaded hole 62 through the threaded connection with the threaded hole 62. The limiting rubber ring 64 at the end of the adjusting rod 63 protrudes from the top of the threaded hole 62, and the support rod 61 is rotated to retract the support rod 61 into the storage groove 51. During this process, the limiting rubber ring 64 contacts the inner wall of the storage groove 51 and deforms. Under the reaction force of the deformation of the limiting rubber ring 64, the support rod 61 is fixed in the storage groove 51.

[0036] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made within the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
