DETAILED DESCRIPTION
[0017] The technical scheme in the utility model embodiment will be clearly and completely described below with specific embodiments and drawings. Figs. 1-3 The technical scheme in the utility model embodiment will be clearly and completely described below with specific embodiments and drawings.
[0018] A portable telescopic concrete sampling tool, comprising an outer sampling box 1 and an inner sampling box 2, the outer sampling box 1 and the inner sampling box 2 are slidably connected, the top surface and one side surface of the outer sampling box 1 and the inner sampling box 2 are open, the one side surface is assembled at one end opposite to the open end, so that four side surfaces are shielded from the ground, and the concrete can be carried, and the top surface is open, so that the concrete tank truck discharge port position can be directly connected, and the concrete is conveniently obtained.
[0019] The outer side of the outer sampling box 1, that is, the side away from the opening side, is fixedly connected with a rear handle 11, which is convenient for the user to hold and lift the device. The top end of the three sides of the outer sampling box 1 is provided with an anti-overflow plate 4, which is in the form of an opening, which is conducive to receiving concrete and preventing spilling. The concrete that drips on the anti-overflow plate 4 can also slide along the inclined surface of the anti-overflow plate 4 into the outer sampling box 1, thereby saving concrete waste and keeping the ground clean. On the inner side of the outer sampling box 1, two opposite sides are provided with slide rails 21 grooves 12 at the same height. The slide rails 21 grooves 12 are arranged in the horizontal direction. Two slide rails 21 are fixedly provided on the outer side of the inner sampling box 2 corresponding to the slide rails 21 grooves 12. The slide rails 21 are connected in the slide rails 21 grooves 12, so that the inner sampling box 2 can slide relative to the outer sampling box 1. The relative sliding can adjust the volume of the accommodating space of the device to match different sizes of measuring tools and hold different amounts of concrete. The top edge of the inner sampling box 2 is also provided with an anti-overflow plate 4.
[0020] A plurality of positioning grooves 211 are provided on the slide rails 21 at a certain distance. Two positioners 3 are slidably connected to the outer sampling box 1. The two positioners 3 are arranged on the two opposite sides of the outer sampling box 1. The sliding direction of the positioner 3 is in the vertical direction. The positioner 3 includes a positioning block 31 and a push block 32. The positioning block 31 and the push block 32 are fixedly connected. The positioning block 31 is in the shape of an arrow. Positioning holes for the vertical sliding of the positioner 3 are provided on the two opposite sides of the outer sampling box 1. The push block 32 is in the shape of a ⊥. One end of the push block 32 penetrates the positioning hole and is fixedly connected with the positioner 3. The positioning block 31 is located in the outer sampling box 1.

The sliding stroke of the push block 32 is always in a compressed state of the spring 33, so that the positioning block 31 is always subjected to the upward elastic force of the spring 33. When the outer sampling box 1 and the inner sampling box 2 are assembled and connected together, the positioning block 31 is always pressed against the slide rails 21. When the slide rails 21 slide to the positioning grooves 211, the positioning block 31 is inserted into the positioning grooves 211 under the pressure of the spring 33. Therefore, the outer sampling box 1 and the inner sampling box 2 can be relatively fixed, maintaining a fixed capacity. Different positioning grooves 211 represent different volumes. By pushing the push block 32 with the hand, the positioning block 31 can be separated from the positioning grooves 211, so that the device reenters the sliding adjustment state.
[0021] The side end of the inner sampling box 2 is fixedly connected with a sealing strip, which can prevent the stored concrete between the outer sampling box 1 and the inner sampling box 2 from flowing out of the gap between the two, affecting the sliding adjustment of the two.
[0022] The inner sampling box 2 is fixedly connected with a pouring opening 22 on the side away from the outer sampling box 1, the pouring opening 22 is communicated with the inner sampling box 2, the inner sampling box 2 is slidably connected with a sealing baffle 24, the sealing baffle 24 slides up and down, can completely close the pouring opening 22 and the inner sampling box 2, after closing, the device can be used to quantitatively take the concrete, opening the sealing baffle 24 can guide the concrete into the measuring equipment through the pouring opening 22, convenient to use, quantitatively take, will not cause waste, the pouring opening 22 is shrinked, can prevent the waste caused by the concrete spilling, the pouring opening 22 is fixedly connected with a front handle 23, convenient to transfer the device.
[0023] In addition to the technical features described in the specification, they are known to those skilled in the art.
[0024] In the utility model, "up", "down", "left", "right", "front", "back" are relative positions for the convenience of describing the positional relationship, and therefore cannot be understood as absolute positions for limiting the protection scope.
[0025] The above content is only an example and description of the structure of the utility model, and those skilled in the art can make various modifications or supplements or use similar ways to replace the described specific embodiments, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the present claims, which shall belong to the protection scope of the utility model.
