Description

Technical Field

[0001] This utility model relates to the field of plastic flooring testing technology, and in particular to a tensile testing device for plastic flooring. Background Technology

[0002] Plastic flooring, also known as flooring made of plastic materials, can be categorized into two types based on its usage: tiles (or floor tiles) and rolls (or linoleum). The main advantage of tiles is that if a section is damaged, it can be replaced without affecting the overall appearance of the floor. However, it has more seams and a slower installation speed. Rolls, on the other hand, offer faster installation and fewer seams. Thicker rolls can be laid directly onto the subfloor without adhesive. However, repairing damaged sections is inconvenient, and replacing the entire roll wastes a significant amount of material. Based on its material, plastic flooring can be classified into rigid, semi-rigid, and flexible types. Based on its basic raw materials, it can be categorized into several types, including polyvinyl chloride (PVC), polyethylene, and polypropylene (PP).

[0003] Before plastic flooring leaves the factory, it undergoes tensile testing. The commonly used tensile testing equipment is relatively cumbersome to position during the testing process, and it is prone to loosening during the testing, which affects the normal testing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a tensile testing device for plastic flooring, thereby solving the problems mentioned in the background section.

[0005] A tensile testing device for plastic flooring includes a workbench and a tensile testing mechanism mounted on the workbench. The tensile testing mechanism includes a connecting plate, a fixed column, a connecting shaft, a limiting frame, a first pressure application part, bolts, and a second pressure application part. The connecting plate consists of two sets arranged opposite to each other. One set is movable and fixedly connected to the output end of a hydraulic cylinder via a tensile sensor. The other set is fixed to the workbench. The connecting shaft is movably connected to the connecting plate via the fixed column and passes through the limiting frame to be fixedly connected to the second pressure application part. The first pressure application part is adjustablely mounted on the upper end plate of the limiting frame via bolts. The limiting frame moves along a slide rail on the workbench.

[0006] By adopting the above technical solution, the device not only facilitates locking the plastic flooring but also increases the constraint on the plastic flooring, preventing the plastic flooring from becoming loose during tensile testing and affecting the normal tensile testing.

[0007] A support plate is fixedly installed between the two sets of connecting plates on the workbench, and the upper surface of the support plate is flush with the upper surface of the lower end plate of the limit frame.

[0008] The above technical solution facilitates the installation of plastic flooring.

[0009] Two waist holes are opened in the middle plate of the limiting frame, and two sets of connecting shafts are set on each set of connecting plates. There are two connecting shafts in each set, which pass through the two waist holes respectively.

[0010] By adopting the above technical solution, the height of the second pressure-applying part can be adjusted according to the thickness of the plastic flooring, so that it can apply pressure to the plastic flooring.

[0011] The connecting shaft can be moved up and down along the fixed column.

[0012] By adopting the above technical solution, the pressure application section 2 is adjusted.

[0013] The second pressure-applying part is generally arranged in a right-angled trapezoidal shape, with its upper end surface being an inclined surface. The first pressure-applying part has a slot in the middle, and the width of the slot is adapted to the width of the second pressure-applying part.

[0014] By adopting the above technical solution, it is possible to enhance the restriction of the plastic floor by the pressure application section 2 behind the hydraulic cylinder.

[0015] The beneficial effects of this utility model's tensile testing device for plastic flooring are:

[0016] A hydraulic cylinder pulls a set of movable connecting plates, which in turn pull the second pressure-applying part via a connecting shaft until the second pressure-applying part stops moving into the limiting frame. The plastic floor is initially constrained by the first pressure-applying part and bolts. After being driven by the hydraulic cylinder, the plastic floor is pulled up. With both sides of the plastic floor constrained, the plastic floor will drive the limiting frame, which is in the same group as the fixed connecting plates, to move towards the support plate. At this time, the second pressure-applying part will also gradually retract into the limiting frame, increasing the pressure constraint on the plastic floor. By observing the data transmitted by the tension sensor in real time, the tension of the plastic floor can be detected. This device facilitates locking the plastic floor while increasing the constraint on it, preventing the plastic floor from loosening during the tension detection process and affecting the normal tension detection.

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0021] Reference Figure 1-2 A tensile testing device for plastic flooring includes a workbench 1 and a tensile testing mechanism installed on the workbench 1. The tensile testing mechanism includes a connecting plate 4, a fixing column 5, a connecting shaft 6, a limiting frame 7, a first pressure part 8, bolts 9, and a second pressure part 10. The connecting plate 4 is arranged in two sets opposite to each other. One set is movable and is fixedly connected to the output end of the hydraulic cylinder 2 through a tensile sensor 3. The other set is fixed on the workbench 1. The connecting shaft 6 is movably connected to the connecting plate 4 through the fixing column 5 and passes through the limiting frame 7 and is fixedly connected to the second pressure part 10. The first pressure part 8 is adjustablely installed at the upper end plate of the limiting frame 7 through bolts 9. The limiting frame 7 moves along the slide rail 101 on the workbench 1.

[0022] Place the plastic flooring on the support plate 11 and move one side of it toward a fixed set of connecting plates 4 until it extends into the limiting frame 7 and fits against the limiting frame 7. Then, rotate the bolt 9 to push the pressure part 8 downward to apply pressure to the plastic flooring. Tighten it with the external wall tool to limit it in the limiting frame 7. Then, drive the hydraulic cylinder 2 to push the movable set of connecting plates 4 toward the plastic flooring until the other side of the plastic flooring is also embedded in another set of limiting frames 7. Similarly, rotate the other set of bolts 9 to push the pressure part 8 downward to tighten it and apply pressure to limit the plastic flooring.

[0023] At this point, the hydraulic cylinder 2 can be driven to pull a set of movable connecting plates 4. The connecting plates 4 will first pull the second pressure part 10 through the connecting shaft 6. Since the upper end face of the second pressure part 10 is in an inclined state, when the connecting shaft 6 pulls the second pressure part 10 into the limiting frame 7, it will gradually increase the pressure on the plastic floor until the second pressure part 10 no longer moves into the limiting frame 7. Since the plastic floor is first limited by the first pressure part 8 and the bolt 9, after the hydraulic cylinder 2 drives it, the plastic floor is pulled up. With both sides of the plastic floor limited, the plastic floor will drive the limiting frame 7, which is in the same group as the fixed connecting plates 4, to move towards the support plate 11. At this time, the second pressure part 10 in the same group will also gradually retract into the limiting frame 7, increasing the pressure limitation on the plastic floor. By observing the data transmitted by the tension sensor 3 in real time, the tension detection of the plastic floor can be completed.

[0024] This device facilitates locking the plastic flooring while also providing additional constraints on it, preventing the plastic flooring from becoming loose during tensile testing and affecting the normal tensile testing process.

[0025] A support plate 11 is fixedly installed between the two sets of connecting plates 4 on the workbench 1. The upper surface of the support plate 11 is flush with the upper surface of the lower end plate of the limiting frame 7, so as to move the plastic floor into the limiting frame 7 and apply pressure to limit it through the first pressure part 8 and the second pressure part 10.

[0026] Two waist holes 701 are opened in the middle plate of the limiting frame 7. Two sets of connecting shafts 6 are set on each set of connecting plates 4. There are two connecting shafts 6 in each set, which pass through the two waist holes 701 respectively. Since the plastic floor has different thicknesses, the connecting shafts 6 can be moved up and down along the fixed column 5 to adjust the height of the pressure part 10. The waist holes 701 allow the connecting shafts 6 to move up and down along the fixed column 5 without restriction.

[0027] The second pressure section 10 is generally arranged in a right-angled trapezoidal shape, with its upper end surface being inclined. The middle of the first pressure section 8 has a slot, the width of which is adapted to the width of the second pressure section 10. After the plastic floor is pulled up, the second pressure section 10 will also be subjected to tension. After the second pressure section 10 extends into the limiting frame 7, it further cooperates with the first pressure section 8 to apply pressure and limit the plastic floor, thereby preventing the plastic floor from falling out during the testing process and affecting normal testing.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
