DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: an adjustable pressure plate assembly, comprising a pressure plate 1, a support seat 2 is provided at the central axis below the pressure plate 1, an auxiliary rod 3 is installed at the lower corner of the pressure plate 1 by screws, a slide cylinder 4 is attached to the outer wall of the auxiliary rod 3, and a barb 5 is provided at the lower side of the pressure plate 1;

[0022] A folding plate 101 is provided at the upper corner of the pressure plate 1 through a latch, a slide rail 102 is provided at the upper middle part of the pressure plate 1, a movable plate 106 is fitted inside the slide rail 102, a fixing groove 105 is provided inside the slide rail 102, a connecting wire 103 is fitted inside the movable plate 106, and a limiting block 104 is fitted on one side of the connecting wire 103.

[0023] In this embodiment, Figure 1 , Figure 2 and Figure 4As shown, a slide groove 202 is welded inside the support seat 2, and a threaded rod 201 is connected inside the slide groove 202 by a thread, and a lifting column 207 is attached to the outer wall of the support seat 2. A first bevel gear 206 is arranged above the threaded rod 201, and a second bevel gear 204 is meshed on one side of the first bevel gear 206. A plug rod 205 is inserted inside the second bevel gear 204, and a rotating handle 203 is inserted on one side of the plug rod 205. The second bevel gear 204 forms a rotating structure through the plug rod 205, and the first bevel gear 206 forms a rotating structure through the second bevel gear 204. The depth and type of the foundation will vary depending on the geographical location and building characteristics. If the pressure plate 1 cannot adjust its height, it may not be able to adapt to foundations of different depths and types, resulting in inaccurate test results or inability to conduct effective tests. Turn the handle 203 clockwise to drive the insertion rod 205 to rotate, and the insertion rod 205 drives the second bevel gear 204 to rotate. The second bevel gear 204 is meshed and connected with the first bevel gear 206. The first bevel gear 206 enables the threaded rod 201 to rise and fall, making it convenient for the lifting column 207 to adjust the height of the pressure plate 1. The depth of the foundation will vary depending on the geographical location and building type. By adjusting the height of the pressure plate 1, it can be ensured that the test device can adapt to foundations of different depths, thereby conducting effective tests.

[0024] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the lifting column 207 forms a sliding structure through the threaded rod 201, and the pressure plate 1 forms a sliding structure through the lifting column 207; different depths of the foundation may lead to different soil properties under the foundation, such as density, compressibility, etc. The inability to adjust the height of the pressure plate 1 may lead to poor contact between the test device and the foundation, and it is impossible to effectively transfer stress or read test data, thereby increasing the test error. The external structural dimensions of the threaded rod 201 are consistent with the internal structural dimensions of the slide groove 202. The threaded rod 201 enables the lifting column 207 to move vertically on the support seat 2. Adjusting the height of the pressure plate 1 can ensure that the contact surface between the test device and the foundation is in the correct position, ensuring that the pressure applied during the test is uniform and accurate, thereby improving the accuracy and reliability of the test data.

[0025] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, the external structure of the limit block 104 is consistent with the internal structure size of the fixed groove 105, and the limit blocks 104 are symmetrically arranged on both sides of the connecting wire 103, and the internal holes of the movable plate 106 are consistent with the arc shape of the holes of the fixed groove 105; the widths of different foundations will be different. If the pressure plate 1 cannot adjust the width, it may not be able to adapt to foundations of different widths, resulting in inability to perform effective testing. Limit blocks 104 are provided on both sides of the connecting wire 103. Squeezing the connecting wire 103 can make the limit blocks 104 disengage from the fixed groove 105, so as to quickly fix the adjusted width of the pressure plate 1 for self-locking and avoid movement, so as to adapt to the widths of different foundations. By adjusting the width of the pressure plate 1, it can be ensured that the test device can adapt to foundations of different widths, thereby performing a wider range of tests.

[0026] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the pressure plate 1 forms a telescopic structure through the folding plate 101, and the pressure plates 1 are vertically arranged on both sides of the auxiliary rod 3 and the slide cylinder 4; since the pressure plate 1 cannot adjust the width, it may be necessary to purchase multiple pressure plates 1 of different widths to adapt to different foundation widths, thereby increasing the cost and management complexity. The pressure plates 1 on both sides are pulled to stretch several pressure plates 1 through the folding plate 101, and the pressure plates 1 are connected to the slide cylinder 4 through the auxiliary rod 3 above and below. The pressure plate 1 can adjust the width through the folding plate 101. Some foundations may have irregular shapes or special geological structures. By adjusting the width of the pressure plate 1, these special foundation shapes can be adapted to ensure the accuracy and reliability of the test results.

[0027] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the pressure plate 1 forms a sliding structure through a movable plate 106 and a slide rail 102; the foundation detection may involve foundations of different widths. If the pressure plate 1 cannot adjust the width, it may not be able to cover all foundation widths that need to be tested, thereby limiting the scope and reliability of the test. A movable plate 106 is provided on one side of the pressure plate 1 and a slide rail 102 is provided on the other side of the pressure plate 1. The pressure plate 1 can be moved by the movable plate 106 and the slide rail 102 to ensure that the adjustment distance of several pressure plates 1 is achieved.

[0028] The use method and advantages of the utility model: When the adjustable pressure plate assembly is used, the working process is as follows:

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first turn the handle 203 clockwise to drive the insertion rod 205 and the second bevel gear 204 to rotate in turn, the second bevel gear 204 is meshed with the first bevel gear 206, the lifting column 207 inside the first bevel gear 206 rotates, and the lifting column 207 is connected to the thread of the threaded rod 201, so that the threaded rod 201 moves downward through the lifting column 207, and the pressure plate 1 moves upward through the auxiliary rod 3, which is convenient for adjusting the height and adapting to different foundations for testing. The small cylinder inside the moving plate 106 moves the connecting wire 103 and the limit block 104 horizontally to one side in turn, and the limit block 104 disengages from the fixing groove 105, so that the moving plate 106 moves inside the slide rail 102, which is convenient for locking and fixing between the pressure plates 1. The pressure plate 1 moves through the folding plate 101, which is convenient for adjusting the width of the pressure plate 1 to adapt to different foundation tests. The bottom of the pressure plate 1 is provided with a barb 5 for fixing.
