Description

Technical Field

[0001] The utility model relates to the field of road surface detection devices, in particular to a windshield used for an artificial sand paving instrument. Background Art

[0002] The artificial sand paving instrument is an instrument used to measure the macro-roughness of the road surface, which mainly includes a measuring cylinder, a paving board, a windshield and a construction depth gauge. When in use, first measure a certain amount of dry sand through a measuring cylinder, then pour the dry sand on the road surface, and use the paving board to carefully spread the sand in a circular motion on the road surface, and spread it as round as possible, and then use the construction depth gauge to pass through the center of the sand surface and measure two construction depth values ​​perpendicular to each other, and take the average value to represent the construction depth of this point on the road surface. During the measurement process, the windshield is used to enclose the measurement area to prevent the wind from affecting the measurement during outdoor measurements. In the prior art, the windshield is formed by connecting multiple baffles to each other, and its mass is relatively light. Once encountering an instantaneous strong wind, the windshield will also be blown away, and it can only cope with a breeze environment.

[0003] In addition, the setting of the windshield will also affect whether the circle formed when spreading dry sand is standard. When spreading, the measurement personnel are easily disturbed by the shape of the windshield. If the shape of the windshield is far from the circle after opening, it will also affect the shape of the spread.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

[0020] The utility model provides a windshield for an artificial sand-laying instrument. To make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] In the description of the present utility model, it should be understood that the terms "upper", "lower", "left", "right", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, and a specific direction structure and operation, and therefore, cannot be understood as a limitation on the present utility model. In addition, "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means more than two.

[0022] See also Figure 1 and Figure 2 The utility model provides a windshield for an artificial sand paving instrument, comprising a plurality of baffles 1 connected end to end in sequence, two adjacent baffles 1 being movably connected, wherein an insert 11 is provided on the outer surface of at least one baffle 1; and at least one counterweight 2 is further provided, wherein a slot 21 is provided on the side wall of the counterweight 2, and the insert 11 is inserted into the slot 21. Specifically, the insert 11 and the slot 21 are detachably connected. When in use, the windshield is first opened to form a regular polygon, and then the counterweight 2 is assembled with the insert 11. When the baffle 1 is blown by the wind, a large wind resistance area is formed on the upper part. When the baffle 1 tends to fall or be blown away, the insert 11 is limited by the counterweight 2 and remains stationary, so that the baffle 1 will not fall down; the counterweight 2 also increases the friction between the windshield and the road surface, making it difficult to be blown away.

[0023] See also Figure 2 In a preferred embodiment, the insert 11 is a metal insert 11, and a magnet 22 is provided in the slot 21, and the magnet 22 is used to tightly attract the metal insert 11. The use of the magnet 22 to fix the metal insert 11 is convenient for disassembly and has good firmness.

[0024] In a preferred embodiment, the magnet 22 is disposed on the bottom wall of the slot 21, and the top surface of the magnet 22 is flush with the bottom wall of the slot 21. Specifically, the height of the slot 21 is the same as the thickness of the metal insert 11, and the top surface of the magnet 22 is flush with the bottom wall of the slot 21, which can ensure that the distance from the top surface of the magnet 22 to the top wall of the slot 21 is equal to the thickness of the metal insert 11. By fixing the magnet 22 in the slot 21 in an inlaid manner, the overall structure can be made simpler.

[0025] See also Figure 2In a preferred embodiment, a mounting groove 23 is provided on the bottom wall of the slot 21, and the magnet 22 is fixed in the mounting groove 23. Specifically, the mounting groove 23 extends along the width direction of the counterweight 2. The height of the slot 21 is very small, only the thickness of the metal insert 11. Therefore, it is not easy to accurately fix the magnet 22 in the slot 21. By providing the mounting groove 23, it is easy to fix the magnet 22 in place. Specifically, an adhesive is provided on the back of the magnet 22.

[0026] See also Figure 2 In a preferred embodiment, a cushion layer 24 is provided at the bottom of the counterweight 2. Specifically, anti-skid patterns are provided at the bottom of the cushion layer 24. The cushion layer 24 is used to increase the friction between the bottom of the counterweight 2 and the road surface.

[0027] See also Figure 3 In a preferred embodiment, in the windshield for the artificial sand paving instrument, the baffle 1 is provided with eight pieces, including four first vertical plates 12 and four second vertical plates 13; the insert 11 is provided on the outer surface of the first vertical plate 12, and the insert 11 is not provided on the outer surface of the second vertical plate 13; the first vertical plates 12 and the second vertical plates 13 are staggered; the windshield also includes four counterweights 2. In this embodiment, by staggeredly arranging the first vertical plates 12 and correspondingly arranging the corresponding counterweights 2, the baffle 1 can be strengthened and fixed on all sides. When in use, the overall structure is more stable and not easy to be blown crooked or blown away.

[0028] See also Figure 3 and Figure 4 In a preferred embodiment, the windshield for the artificial sand paving device further includes two shaping strips 3, and the two ends of the shaping strips 3 are respectively provided with downward opening slots 31, and the width of the slots 31 is the same as the thickness of the baffle 1; the slots 31 at both ends of the shaping strips 3 are respectively engaged with the two oppositely arranged baffles 1, so as to form the windshield into a regular octagon. When in use, the two shaping strips 3 are vertically arranged to fix the distance between the two oppositely arranged baffles 1. After the positions of the four staggered baffles 1 are fixed, the other four baffles 1 are also fixed in position under the pull of the first four baffles 1. Specifically, the two shaping strips 3 have the same length, and their lengths are the same as the distance between the two opposite baffles 1 when the windshield forms a regular octagon. In order to prevent the shaping strips 3 from hindering the use of the paving board, the shaping strips 3 can be taken out after the windshield is shaped.

[0029] In summary, the utility model provides a counterweight 2 and an insert 11 on the outer side of the baffle 1. Through the use of the counterweight 2 and the insert 11, the windshield can be stably placed on the road surface after opening and has good wind resistance.
