Description

Technical Field

[0001] The invention relates to the technical field of laser distance measuring equipment, and in particular to a portable construction measuring equipment. Background Art

[0002] Laser rangefinder is an instrument that uses a certain parameter of modulated laser to accurately measure the distance to the target. When working, the pulse laser rangefinder emits a beam or a series of short pulse laser beams to the target. The photoelectric element receives the laser beam reflected by the target. The timer measures the time from the emission to the reception of the laser beam and calculates the distance from the rangefinder to the target. The laser rangefinder is light in weight, small in size, simple to operate, fast and accurate, and its error is only one-fifth to several hundredths of other optical rangefinders.

DETAILED DESCRIPTION

[0037] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] Example 1

[0039] A portable construction measuring device, such as Figure 1-Figure 7 As shown, it includes a laser measuring device 1, a protective shell 11, a rotating shaft 12, a first mounting plate frame 13, a bracket 14, a magnet 15 and an indicator plate 16. The first mounting plate frame 13 is fixedly connected to the left side of the laser measuring device 1. The rotating shaft 12 is rotatably connected to the front and rear sides of the first mounting plate frame 13. A clamping groove is provided on the sides of the two rotating shafts 12 that are away from each other. The protective shell 11 is fixedly connected to the outside of the rotating shaft 12. The bracket 14 is fixedly connected to the front side of the front protective shell 11. The upper and lower parts of the right side of the protective shell 11 are fixedly connected to the magnets 15. The upper part of the front protective shell 11 is slidably connected to the indicator plate 16.

[0040] like Figure 1 As shown, the protective shell 11 is made of silicone.

[0041] like Figure 6 As shown, the indicator plate 16 itself is foldable.

[0042] When workers need to use the laser measuring device 1 to measure the distance between two locations or objects during construction, they can first rotate the two protective shells 11 forward or backward 180 degrees and open them, then place the laser measuring device 1 on the horizontal plane of one location or the plane of the object, and let the laser emitted by the laser measuring device 1 shoot at the other location or object to measure the distance between the two. During this period, the two protective shells 11 can provide stable support for the laser measuring device 1 to prevent the laser measuring device 1 from shaking and deflecting during measurement, thereby affecting the accuracy of the measurement data. Since the laser measuring device 1 needs to make the emitted laser hit the target and be reflected back to perform accurate distance measurement, if there is no suitable reflective target at the other location or object, it can be The indicator plate 16 on the upper part of the front protective shell 11 is taken out and folded into an L shape, and then the indicator plate 16 is placed or fixed at the target position, so that the laser hits the indicator plate 16 and the measurement is performed. After the measurement is completed, the indicator plate 16 is restored to its original state and put back into the protective shell 11, and then the two protective shells 11 are rotated 180 degrees in the opposite direction and closed. At this time, the magnets 15 in the two protective shells 11 will approach each other and be adsorbed and fixed together, thereby preventing the protective shells 11 from being easily opened. Finally, the device can be stored in a pocket or a backpack, or the device can be fixed in the worker's waist or chest pocket with the help of the card holder 14. The protective shell 11 made of silicone material can also provide good buffering and protection for the laser measuring device 1 when the device accidentally falls.

[0043] Example 2

[0044] On the basis of Example 1, Figure 8-Figure 10 As shown, a fixing mechanism for stably placing the laser measuring device 1 is also included. The fixing mechanism is arranged on the laser measuring device 1. The fixing mechanism includes a second mounting plate frame 2, a rotating handle 21, a pushing frame 22, a pin 23, a gear 24, a rack 25 and a screw 26. The second mounting plate frame 2 is fixedly connected to the bottom of the laser measuring device 1. The pushing frame 22 is slidably connected inside the second mounting plate frame 2. The left and right sides of the bottom of the second mounting plate frame 2 are rotatably connected to the pin 23. The front and rear sides of the pin 23 are fixedly connected to the gear 24. The left and right sides of the pushing frame 22 are fixedly connected to the racks 25 symmetrically distributed front and back. The gear 24 is meshed with the adjacent rack 25. The left side of the second mounting plate frame 2 is rotatably connected to the screw 26. The screw 26 is threadedly connected to the pushing frame 22, and the left end of the screw 26 is fixedly connected to the rotating handle 21.

[0045] When the worker needs to place the laser measuring device 1 on a soft surface such as soil or sand for measurement, the worker can also rotate the screw rod 26 through the turning handle 21 after the protective shell 11 is opened, thereby driving the push frame 22 and the rack 25 to move to the left, and the rack 25 moves to the left to engage with the adjacent gear 24, and drives the gear 24 and the pin 23 to rotate 90° counterclockwise to become a vertical state. At this time, if the laser measuring device 1 and the protective shell 11 are placed on a soft surface such as soil or sand, the pin 23 will be inserted downward into the soil or sand, thereby further fixing and supporting the laser measuring device 1 to prevent the laser measuring device 1 from shaking and deflecting during measurement. After the measurement is completed, the laser measuring device 1, the protective shell 11, the pin 23 and other components are picked up, and the turning handle 21 and the screw rod 26 are rotated in the opposite direction to move the push frame 22 and the rack 25 to the right to reset, thereby driving the gear 24 and the pin 23 to rotate 90° clockwise to reset, and finally the protective shell 11 is closed.

[0046] like Fig.11 and Fig.12 As shown, it also includes an adhesion mechanism for adhering and fixing the laser measuring device 1, the adhesion mechanism is arranged on the protective shell 11, the adhesion mechanism includes an adhesion plate 3, a telescopic rod 31 and a spring 32, three groups of telescopic rods 31 are respectively fixed to the upper left and right sides and the lower right side of the front protective shell 11, and each group includes two telescopic rods 31, the adhesion plate 3 is fixed between the telescopic ends of the two telescopic rods 31 in one group, and the spring 32 is fixed between the adhesion plate 3 and the fixed end of the adjacent telescopic rod 31.

[0047] like Fig.12 As shown, the adhesive plate 3 is composed of multiple layers of single-sided adhesive sheets.

[0048] When it is necessary to measure the width of an object such as a window or a mounting frame, if there is no horizontal plane for placing the laser measuring device 1, the protective shell 11 can be opened, and the adhesive plates 3 on the upper left and right sides and the lower left side of the front protective shell 11 can be placed against the vertical wall or plane near the window or the mounting frame. During this period, the adhesive plates 3 will first contact and adhere to the vertical wall or plane, and the laser measuring device 1 and the protective shell 11 will continue to move, which will compress the telescopic rod 31 and the spring 32. Under the action of the compressed spring 32 and the telescopic rod 31, the adhesive plates 3 can adhere more firmly. Then the worker can loosen the laser measuring device 1 and the protective shell 11. At this time, the laser measuring device 1 and the protective shell 11 will first be on the telescopic rod 3. 1 and the spring 32 move in the opposite direction to reset, and the adhesive plate 3 can firmly adhere and fix the laser measurer 1 and the protective shell 11 to the vertical wall or plane for measurement, so as to prevent the laser measurer 1 from being offset when the measurement is supported by hands. After the measurement is completed, the laser measurer 1, the protective shell 11 and the adhesive plate 3 are removed from the vertical wall or plane, and the protective shell 11 is closed. When the laser measurer 1 and the protective shell 11 are adhered to the vertical wall or plane with the help of the adhesive plate 3 next time, it is necessary to tear off the used adhesive sheet of the outermost layer of the adhesive plate 3 in advance, and then use a new adhesive sheet to stick, so as to ensure that the adhesiveness of the adhesive plate 3 is sufficient to fix the laser measurer 1 and the protective shell 11 to the vertical wall or plane.

[0049] like Fig.13 As shown, it also includes a horizontal mechanism for ensuring that the laser measurer 1 is in a horizontal state. The horizontal mechanism is arranged on the laser measurer 1. The horizontal mechanism includes a horizontal tube 4 and a fixed block 41. The fixed block 41 is fixedly connected to the right side of the laser measurer 1. The horizontal tube 4 is fixedly connected to the right side of the fixed block 41.

[0050] Before measuring, it is necessary to continuously adjust the position and state of the laser measurer 1 and the protective shell 11 according to the level tube 4 to ensure that the laser measurer 1 is in a horizontal state during measurement, so as to avoid deviation of the emitted laser due to deviation of the measuring angle of the laser measurer 1, thereby causing inaccurate measurement data.

[0051] like Fig.14 and Fig.15As shown, it also includes a limiting mechanism for limiting the protective shell 11, which is arranged on the first mounting plate frame 13. The limiting mechanism includes a pressure block 5, a connecting rod 51, a clamping block 52, a connecting plate 53, an inclined block 54 and a spring piece 55. The pressure block 5 is slidably connected to the top of the first mounting plate frame 13, and a connecting rod 51 is fixedly connected to the bottom of the pressure block 5. The connecting rod 51 is slidably connected to the first mounting plate frame 13, and an upper and lower inclined block 54 is fixedly connected to the lower part of the connecting rod 51. The clamping block 52 is slidably connected to the rotating shaft 12 on both the front and rear sides of the first mounting plate frame 13. The clamping block 52 is slidably connected to the rotating shaft 12, and a connecting plate 53 is fixedly connected to the side where the two clamping blocks 52 are close to each other. The inclined block 54 is squeezed and matched with the adjacent connecting plate 53, and a spring piece 55 is fixedly connected between the connecting plate 53 and the first mounting plate frame 13.

[0052] like Fig.15 As shown, the upper and lower inclined blocks 54 are oriented in opposite directions.

[0053] like Fig.15 As shown, the front and rear connecting plates 53 are centrally symmetrically distributed.

[0054] When the worker rotates the two protective shells 11 180 degrees and opens them, the two shafts 12 are also rotated 180 degrees, and the slots of the shafts 12 are opposite to the block 52. At this time, the two connecting plates 53 and the block 52 move backwards under the action of the spring 55 and snap into the slots adjacent to the shafts 12, thereby limiting and fixing the shafts 12 and the opened protective shell 11, preventing the laser measuring device 1 from rotating relative to the protective shell 11 during measurement and causing deviation. It will contact and squeeze the adjacent inclined block 54, and move the inclined block 54, the connecting rod 51 and the pressure block 5 upward. After the measurement is completed, the pressure block 5 can be pressed downward to move the pressure block 5, the connecting rod 51 and the inclined block 54 downward to reset and squeeze the connecting plate 53, so that the two connecting plates 53 and the card block 52 move toward each other to reset, and the spring piece 55 will be deformed and stretched immediately. At this time, the protective shell 11 and the rotating shaft 12 are no longer restricted and can be rotated in the opposite direction to reset. After the protective shell 11 is reset and closed, the pressure block 5 can be released.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
