Description

Technical Field

[0001] The utility model relates to the field of bonding strength testing equipment, in particular to a device for detecting the bonding strength of a cement-based self-leveling interface agent. Background Art

[0002] Cement-based self-leveling interface agent is a product specially used to adjust the interface between the cement-based self-leveling layer and the underlying material. It can significantly improve the adhesion between the cement-based self-leveling layer and the underlying material, thereby enhancing the overall performance and stability. It is mainly composed of polymer emulsion, viscosity-enhancing binder, stabilizer and other ingredients. It is a liquid additive. When the interface agent dries, it will form a layer of emulsion film. This film has waterproof and hydrophobic effects, which can prevent water from "seeping" into the self-leveling during the drying process to form bubbles and small holes, thereby ensuring the density of the self-leveling.

[0003] In the process of preparing cement-based self-leveling interface agent, bonding strength testing equipment is generally used to test the prepared cement-based self-leveling interface agent to ensure that it meets the preset standards, which helps to timely discover potential problems in the process of product production and ensure the stability and reliability of product quality. The bonding strength testing devices currently used are generally tensile type, which drives the lead screw set at the center of the interior to move linearly by turning the hand wheel set on the side, thereby applying tension to the bottom connection block, so as to test the bonding strength of the cement-based self-leveling interface agent bonded to the bottom of the connection block;

[0004] During the test using the bond strength testing equipment, when the handwheel suddenly rotates quickly or stops abruptly, the friction between the handwheel and the lead screw will undergo a transition from static friction to dynamic friction. This sudden change in friction state may cause the contact state between the lead screw and the handwheel to become unstable, resulting in a slight deviation of the lead screw, reducing the stability of the lead screw and the accuracy of the test.

[0005] Therefore, it is necessary to provide a new cement-based self-leveling interface agent bonding strength detection device to solve the above technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a device for detecting the bonding strength of a cement-based self-leveling interface agent.

[0007] The utility model provides a device for detecting the bonding strength of a cement-based self-leveling interface agent, comprising a testing device for testing the bonding strength, wherein a lead screw is vertically arranged at the inner center of the testing device, and a hand wheel for driving the lead screw is arranged on the outer side of the testing device, T-slots are arranged on both sides of the inner wall of the testing device, a plurality of support rods are fixedly arranged on the outer side of the lead screw, and ends of the plurality of support rods away from the lead screw are respectively located at the inner bottom ends of two T-slots, and a connecting column is fixedly arranged at one end of the support rod located inside the T-slot, and a rotating wheel is arranged at one end of the connecting column away from the support rod, the rotating wheel is rotatably connected to the connecting column, and the outer side of the rotating wheel fits with the inner top end of the T-slot.

[0008] Preferably, a charging slot is provided on a side of the testing device away from the handwheel.

[0009] Preferably, a protective member 1 and a protective member 2 are respectively provided on the outer side of the test device, and the protective member 1 includes two limit rods and a protective plate 1, one side of the two limit rods are respectively fixedly connected to the two ends of one side of the test device, and the adjacent sides of the two limit rods are each provided with a slot matching the protective plate 1, and the two sides of the protective plate 1 are respectively located inside the slots opened by the two limit rods.

[0010] Preferably, a flexible pad is provided inside the slot defined by the limiting rod.

[0011] Preferably, the second protective member includes a mounting rod and a second protective plate, the mounting rod is L-shaped, and a slot matching the second protective plate is provided on the inner side of the mounting rod, and the second protective plate is located inside the slot opened on the mounting rod.

[0012] Preferably, a fixed block and a movable block for limiting the position of the screw are provided on the top of the testing device, the bottom of the fixed block is fixedly connected to the top of the testing device, the bottom of the screw passes through the fixed block and extends into the interior of the testing device, and the movable block is threadedly sleeved on the top of the screw.

[0013] Compared with the related art, the device for detecting the bonding strength of cement-based self-leveling interface agent provided by the utility model has the following beneficial effects:

[0014] When the handwheel is turned to drive the lead screw to move in a straight line, the lead screw will drive multiple support rods arranged on the outside to slide at the bottom ends of the two T-slots respectively, and during the sliding process of the support rods, the connecting column and the rotating wheel will be driven to move synchronously. Because the rotating wheel and the connecting column are rotationally connected, the rotating wheel will rotate when it moves at the top end of the T-slot, thereby reducing the friction and resistance between the T-slot and the lead screw, making the movement of the lead screw smoother. By setting the T-slot, support rods and rotating wheels, the stability of the lead screw can be improved to a certain extent, thereby improving the accuracy of the test.

[0025] In the specific implementation process, Figure 1-Figure 7 As shown, a device for detecting the bonding strength of a cement-based self-leveling interface agent is characterized in that it comprises a testing device 1 for testing the bonding strength, a lead screw 2 is vertically provided at the center of the inside of the testing device 1, and a hand wheel 3 for driving the lead screw 2 is provided on the outside of the testing device 1, T-slots 4 are provided on both sides of the inner wall of the testing device 1, a plurality of support rods 5 are fixedly provided on the outside of the lead screw 2, and the ends of the plurality of support rods 5 away from the lead screw 2 are respectively located at the bottom ends of the two T-slots 4, and a connecting column 6 is fixedly provided at one end of the support rod 5 located inside the T-slot 4, and a rotating wheel 7 is provided at one end of the connecting column 6 away from the support rod 5, the rotating wheel 7 is rotatably connected to the connecting column 6, and the outer side of the rotating wheel 7 is in contact with the top end of the T-slot 4, and a charging slot 8 is provided on the side of the testing device 1 away from the hand wheel 3, and the stability of the lead screw 2 during movement is improved by the T-slot 4, the support rod 5 and the rotating wheel 7.

[0026] A protective member 1 and a protective member 2 are respectively provided on the outside of the test device 1. The protective member 1 includes two limit rods 9 and a protective plate 10. One side of the two limit rods 9 is fixedly connected to the two ends of one side of the test device 1, and the adjacent sides of the two limit rods 9 are provided with slots 11 matching the protective plate 10. The two sides of the protective plate 10 are respectively located inside the slots 11 opened by the two limit rods 9. A flexible pad 12 is provided inside the slots 11 opened by the limit rods 9. The protective member 2 includes a mounting rod 13 and a protective plate 2 14. The mounting rod 13 is L-shaped, and a card slot 15 matching the protective plate 2 14 is provided on the inner side of the mounting rod 13. The protective plate 2 14 is located inside the slots 11 opened by the two limit rods 9. Inside the slot 15 opened on the mounting rod 13, a fixed block 16 and a movable block 17 for limiting the lead screw 2 are provided on the top of the test device 1. The bottom of the fixed block 16 is fixedly connected to the top of the test device 1, and the bottom of the lead screw 2 passes through the fixed block 16 and extends into the inside of the test device 1. The movable block 17 is threadedly sleeved on the top of the lead screw 2. By passing the top of the lead screw 2 through the fixed block 16 and sleeved on the top of the lead screw 2, the bottom of the movable block 17 is fit with the top of the fixed block 16. Because the lead screw 2 and the movable block 17 are threadedly connected, and the fixed block 16 blocks the movable block 17, the lead screw 2 is limited.

[0027] The working principle of the utility model is as follows: when the hand wheel 3 is turned to drive the lead screw 2 to perform linear motion, the lead screw 2 will drive multiple support rods 5 arranged on the outside to slide at the bottom ends of the two T-slots 4 respectively, and during the sliding process of the support rods 5, the connecting column 6 and the rotating wheel 7 will be driven to perform synchronous movement. Because the rotating wheel 7 and the connecting column 6 are rotatably connected, when the rotating wheel 7 moves at the top end of the T-slot 4, it will rotate, thereby reducing the friction and resistance between the T-slot 4 and the lead screw 2. The movement is smoother, and the stability of the lead screw 2 during the movement process is improved by the T-slot 4, the support rods 5 and the rotating wheel 7.

[0028] Insert both sides of the protective plate 10 into the slots 11 opened by the two limit rods 9, and increase the contact area between the protective plate 10 and the slots 11 through the flexible pads 12 provided inside the slots 11, thereby enhancing the stability and reliability of the connection. At the same time, the flexible pads 12 can also fill the small gap between the protective plate 10 and the slots 11 to prevent the protective plate 10 from being easily loosened;

[0029] Put the second protective plate 14 into the slot 15 opened on the inner side of the mounting rod 13. Because the mounting rod 13 is L-shaped, the bottom of the mounting rod 13 provides support for the second protective plate 14 to improve the stability of the second protective plate 14. The first protective plate 10 and the second protective plate 14 can effectively prevent the cement-based self-leveling interface agent inside the test equipment 1 from splashing out, and can protect the operator.

[0030] By passing the top of the screw 2 through the fixed block 16 and sleeved the movable block 17 on the top of the screw 2, the bottom of the movable block 17 is fit with the top of the fixed block 16. Because the screw 2 and the movable block 17 are threadedly connected, and the fixed block 16 blocks the movable block 17, the screw 2 is limited.
