Technical Field
[0001] This utility model relates to the field of pressure mechanism technology, specifically a pressure mechanism for testing the compressive strength of building decorative panels. Background Technology
[0002] Architectural decorative panels refer to decorative materials used on the interior and exterior walls, ceilings, floors, and other parts of buildings. They are mainly used to enhance the aesthetics and functionality of buildings. In order to ensure that architectural decorative panels can withstand external pressure during use and to guarantee the safety and durability of buildings, it is necessary to conduct compressive strength tests on architectural decorative panels.
[0003] Since compressive strength testing is a crucial step in the quality inspection of building decorative panels, a corresponding pressure-applying mechanism is required. During the pressure test, a specimen of a certain size is typically cut from the building decorative panel, and pressure is applied until the specimen fails, with the maximum failure load recorded. Therefore, the pressure block generally needs to be in full contact with the specimen. However, in actual use, the stress points of building decorative panels vary, sometimes even to small points. As a result, the cross-section of the pressure block is mostly constant during operation, which can easily affect the pressure test results. Utility Model Content
[0004] The purpose of this utility model is to provide a pressure mechanism for testing the compressive strength of building decorative panels, so as to solve the problem mentioned in the background art that when building decorative panels are actually used, the stress points are varied, for example, sometimes the force is applied to small points, so the cross section of the pressure block is mostly constant during operation, which can easily affect the pressure testing effect.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure mechanism for testing the compressive strength of building decorative panels, comprising a supporting base plate, a pressure block, and side uprights. A mounting base is fixed to the top of the pressure block. A top plate frame is fixed at the upper position between the left and right side uprights. A cylinder is mounted on the top of the top plate frame. A hydraulic telescopic rod is driven to the output end of the cylinder. A connecting plate is fixed to the telescopic end of the hydraulic telescopic rod. A movable plate is bolted to the bottom of the connecting plate. A mounting post is fixed to the bottom of the movable plate. Connecting screw grooves are provided on both sides of the mounting post, and mounting bolts are connected in the connecting screw grooves. Guide holes are provided on both sides of the movable plate. Embedded grooves are connected to both sides of the guide holes, and ball bearings are embedded in the embedded grooves. Mounting brackets are fixed to both sides of the movable plate, and guide wheels are rotatably mounted within the mounting brackets using shafts.
[0006] As a further technical solution of this utility model, the mounting bracket is symmetrically distributed about the central axis of the movable plate, and the groove is distributed in a ring about the center of the guide hole.
[0007] As a further technical solution of this utility model, guide rods are fixed on both sides of the bottom of the top plate frame. The guide rods pass through the inside of the guide holes, and the bottom of the guide rods are connected and fixed to the bottom plate and the side plate.
[0008] As a further technical solution of this utility model, the mounting base is provided with a groove for inserting the column, and screw holes matching the mounting bolts are provided on both sides of the groove.
[0009] As a further technical solution of this utility model, the mounting bolt and the connecting screw groove form a threaded connection, and the screw hole and the mounting bolt form a threaded connection.
[0010] As a further technical solution of this utility model, the guide rods are symmetrically distributed about the central axis of the top plate frame, and the two guide rods slide through the two guide holes respectively.
[0011] As a further technical solution of this utility model, a vertical plate is fixed on the left side of the top of the support base plate, and a first telescopic rod is fixedly installed on the side of the vertical plate. The telescopic end of the first telescopic rod is connected to the side of a side plate.
[0012] As a further technical solution of this utility model, a sliding groove is provided in the top of the supporting base plate, and a slider is fixed at the bottom of the side plate, the slider being embedded in the sliding groove to form a sliding connection.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the pressure mechanism for testing the compressive strength of building decorative panels not only improves the ability to replace pressure blocks, but also improves the movement protection capability and lateral adjustment capability of the pressure mechanism.
[0014] (1) By fixing the mounting base to the top of the pressure block and fixing the insertion post to the bottom of the moving plate, the bottom of the connecting plate is fixed to the moving plate with bolts. Different pressure blocks are selected for assembly according to requirements. During assembly, the insertion post is inserted into the groove of the mounting base, and then the mounting bolts are locked through the screw holes and connecting screw grooves to complete the fixed installation between the mounting base and the insertion post. Therefore, pressure blocks with rectangular, conical, or trapezoidal cross sections can be selected for use, and their compressive strength is tested respectively, thereby improving the replacement capability of the pressure blocks.
[0015] (2) By fixing the guide rods to the two sides of the bottom of the top plate frame, the two guide rods slide through the two guide holes respectively. Therefore, when the moving plate moves, it relies on the guide holes and guide rods to slide and guide. At the same time, the guide wheels on both sides of the moving plate move and roll in contact with the side plate. This process is protected by the groove and the ball, which improves the movement protection capability.
[0016] (3) By fixing the vertical plate to the left side of the top of the support base plate, a slider is fixed at the bottom of the side plate and the slider is embedded in the groove. Therefore, after the first telescopic rod works, the side plate can be pushed to move laterally. At this time, the groove and the slider cooperate to form a sliding movement, so the pressure position of the pressure block can be adjusted laterally, which improves the adjustment capability.
