Description

Technical Field

[0001] This utility model belongs to the field of experimental sample preparation technology, specifically relating to a mortar sample preparation device. Background Technology

[0002] Plastering mortar refers to mortar applied to the surface of buildings or building components. It has the dual function of protecting the base layer and meeting the needs of use. According to different functions, it is divided into various types such as ordinary plastering mortar, decorative mortar, waterproof mortar, and heat insulation mortar. Before using plastering mortar, it is often tested. At this time, it is necessary to use a sample making machine to make plastering mortar samples.

[0003] like Figure 1 The existing plastering mortar sample preparation machine shown consists of three panels: top, middle, and bottom. The top panel has a mold cavity, and the middle panel has a top rod. During sample preparation, the wall material is cut into small pieces and placed into the mold cavity, supported by the top rod. Mortar is then applied to the surface of the wall material until it is flush with the top surface of the mold cavity. Finally, the top rod pushes the sample out to support it. However, this sample preparation machine produces plastering mortar samples of the same thickness at a time and cannot produce samples of multiple thicknesses. This presents a limitation when multiple thicknesses of samples are required. Therefore, we propose a plastering mortar sample preparation device. Utility Model Content

[0004] The purpose of this invention is to provide a mortar sample preparation device to solve the problems existing in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: A mortar sample preparation device includes a base plate, an upper template, and a positioning plate. The positioning plate is located under the base plate. The base plate, the upper template, and the positioning plate are connected and fixed together by a plurality of first vertical rods. The upper template has a plurality of longitudinally arranged through mold cavities, and each group of through mold cavities contains at least two through mold cavities. The lower side of the positioning plate is also provided with a sliding plate, which is slidably connected to each of the first vertical rods. The upper end of the sliding plate is fixed with multiple sets of second vertical rods that match the through mold cavity. Each set of second vertical rods has a set of sleeves slidably connected to its outer wall. The upper end of each set of sleeves slidably passes through the positioning plate and corresponds to each set of through mold cavities. A vertical adjustment mechanism is provided between the sliding plate and each set of sleeves, and a lifting mechanism is provided between the bottom plate and the sliding plate.

[0006] As a further limitation of the present invention, each of the sleeves is provided with a guide rod on the same side. The vertical adjustment mechanism includes: multiple inclined guide rails, each guide rod being inserted into the lower side of each inclined guide rail, and the multiple inclined guide rails being fixed together by a connecting frame; a longitudinal slide groove, which is formed on the surface of the slide plate, and a slider is slidably connected in the longitudinal slide groove, the slider being fixedly installed with the connecting frame; and an adjusting screw, which is rotatably disposed in the longitudinal slide groove, passes through the slider and is threadedly connected to the slider, and a knob is installed at the end of the adjusting screw.

[0007] As a further limitation of the present invention, the lifting mechanism includes: a first mounting base, which is fixedly disposed on the middle side of the bottom of the slide plate, and connecting rods are respectively hinged to both sides of the first mounting base; a second mounting base, which is fixedly disposed on the base plate and located directly below the first mounting base, and the second mounting base is rotatably mounted with rotating rods extending to both sides, the rotating rods having threads with opposite directions machined on both sides, and rotating handles installed at both ends of the rotating rods; and two sliding platforms, which are respectively threadedly rotatably connected to both sides of the rotating rods, and the lower ends of the two connecting rods are respectively hinged to the two sliding platforms.

[0008] As a further limitation of the present invention, the bottom of the base plate is provided with multiple support feet, and the inner wall surface of each of the through mold cavities is also machined with scale patterns.

Detailed Implementation

[0012] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] Example: like Figures 2 to 5 The mortar sample preparation equipment shown includes a base plate 100, an upper template 101, and a positioning plate 102. The positioning plate 102 is located below the base plate 100. The base plate 100, the upper template 101, and the positioning plate 102 are connected and fixed together by a plurality of first vertical rods 103. The upper template 101 has a plurality of longitudinally arranged through mold cavities 1011, and each set of through mold cavities 1011 contains at least two through mold cavities 1011. The lower side of the positioning plate 102 is also provided with a sliding plate 110. The sliding plate 110 is slidably connected to each of the first vertical rods 103. The upper end of the sliding plate 110 is fixed with multiple sets of second vertical rods 111 that match the through mold cavity 1011. Each set of second vertical rods 111 is slidably connected to a set of sleeves 112 on its outer wall. The upper end of each set of sleeves 112 slides through the positioning plate 102 and corresponds to each set of through mold cavities 1011. A vertical adjustment mechanism is provided between the sliding plate 110 and each set of sleeves 112. A lifting mechanism is provided between the bottom plate 100 and the sliding plate 110.

[0014] This embodiment is an improvement based on existing technology. The key improvement is that the sample preparation machine can produce plastering mortar samples of various thicknesses. The specific usage method is as follows: Preparation: Cut the wall material into test pieces that match the shape and specifications of the through mold cavity 1011, and prepare the plastering mortar to be tested. Specimen block placement: The lifting mechanism lowers the slide plate 110 and places the specimen block into the through mold cavity 1011. Then, the top of the sleeve 112 of the slide plate 110 supports the bottom of the specimen block, so that the specimen block is stably placed in the through mold cavity 1011. Sample preparation: If only the upper template 101 is used to make a single thickness of plastering mortar sample, the sleeves 112 are adjusted to the same height by the vertical adjustment mechanisms. The sleeves 112 can change the position of each specimen block in the through mold cavity 1011. Plastering mortar is then applied into the through mold cavity 1011 to make a single thickness of plastering mortar sample. The thickness of the plastering mortar sample is the distance between the upper end face of the through mold cavity 1011 and the upper end face of the specimen block. If the upper template 101 is used to make plastering mortar samples of multiple thicknesses, the sleeves 112 are adjusted to different heights by the vertical adjustment mechanisms. Similarly, the sleeves 112 can change the position of the specimen block in the through mold cavity 1011. Plastering mortar is then applied into the through mold cavity 1011 to make plastering mortar samples of multiple thicknesses at once. Plastering mortar sample ejection: After the plastering mortar sample has been applied and allowed to stand for the required time, the lifting mechanism is operated to move the slide plate 110 upward, thus ejecting the plastering mortar sample from the through mold cavity 1011.

[0015] As a description of the structure and usage of the vertical adjustment mechanism in the above embodiments, such as Figures 3 to 4 As shown, each set of sleeves 112 has a guide rod 120 machined on the same side, and the vertical adjustment mechanism includes: Multiple inclined guide rails 121 are provided, and each guide rod 120 is inserted into the lower side of each inclined guide rail 121. The multiple inclined guide rails 121 are fixed together by a connecting bracket 122. A longitudinal slide groove 123 is provided on the surface of the slide plate 110. A slider 124 is slidably connected in the longitudinal slide groove 122. The slider 124 is installed and fixed to the connecting bracket 122. An adjusting screw 125 is rotatably disposed in the longitudinal slide groove 123. The adjusting screw 125 passes through the slider 124 and is threadedly connected to the slider 124. A knob 126 is installed at the end of the adjusting screw 125.

[0016] When using the vertical adjustment mechanism, people rotate the knob 126 to rotate the adjusting screw 125, which causes the slider 124 to move along the adjusting screw 125 in the longitudinal groove 123, thereby driving the connecting frame 122 and the multiple inclined guide rails 121 connected in the same group to move synchronously. Through the guiding cooperation between the inclined guide rails 121 and the guide rod 120, the guide rod 120 can drive the sleeve 112 to move vertically. The overall structure is simple and practical, and the operation is convenient.

[0017] As a description of the structure and usage of the lifting mechanism in the above embodiments, such as Figure 2 , Figure 3 as well as Figure 5 As shown, the lifting mechanism includes: A first mounting base 130 is fixed to the bottom center of the slide plate 110, and connecting rods 131 are hinged to both sides of the first mounting base 130. A second mounting base 132 is fixed to the base plate 100 and located directly below the first mounting base 130. The second mounting base 132 is rotatably mounted with rotating rods 133 extending to both sides. The rotating rods 133 have threads with opposite directions on both sides, and rotating handles 135 are installed at both ends of the rotating rods 133. Two slides 134 are rotatably connected to the rotating rods 133 by threads on both sides, and the lower ends of the two connecting rods 131 are hinged to the two slides 134 respectively.

[0018] When using the lifting mechanism, people rotate the handle 135 to rotate the rotating rod 133 of the second mounting base 132. Since the rotating rod 133 has threads with opposite directions on both sides, and the two slides 134 are rotatably connected to the threads on both sides of the rotating rod 133, the two slides 134 can move closer or further apart. When the two slides 134 are close to each other, the first mounting base 130 and the slide plate 110 are pushed upward through the transmission of the two connecting rods 131. When the two slides 134 are close to each other, the first mounting base 130 and the slide plate 110 are pulled downward back to their original positions through the transmission of the two connecting rods 131.

[0019] As an example of other optimized structures described in the above embodiments, such as Figure 2 As shown, the bottom of the base plate 100 is also provided with multiple support feet 104, and the inner wall surface of each through mold cavity 1011 is also machined with scale lines 1012.

[0020] The bottom of the support foot 104 can be set as an anti-slip rubber pad to have the functions of shock absorption and anti-slip. The scale pattern 1012 processed through the inner wall of the mold cavity 1011 can make people see the distance between the upper end face of the specimen block and the upper end face of the mold cavity 1011, thereby facilitating the control of the thickness of the plastering mortar sample.

[0021] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
