Description

Technical Field

[0001] This utility model relates to the technical field of tensile testing devices, and in particular to a device for detecting the positive tensile force of a reflector adhesive. Background Technology

[0002] After the adhesive on the finished reflector has cured for a period of time, the bonding effect and capability of the adhesive need to be tested and verified. One important indicator is the "positive tensile strength of the adhesive," which requires testing. Furthermore, the quality control standards for finished reflectors awaiting delivery to customers also include "positive tensile strength of the adhesive," and reflectors transported to customer project construction sites often also require testing of the positive tensile strength of the adhesive. All these situations necessitate a portable, easy-to-operate, and compact device for testing the positive tensile strength of the adhesive.

[0003] The current method of testing the positive tensile strength of adhesives on reflectors requires a laboratory setting. This involves cutting, sampling, and transporting the finished reflectors, and the samples must meet the size requirements of the laboratory's tensile testing equipment. If the samples do not meet the requirements, testing cannot be performed, and the samples must be taken and transported again. This makes the entire sampling, testing, and transport process complicated and may cause damage or delays. Utility Model Content

[0004] The purpose of this invention is to provide a device for detecting the positive tensile force of reflector adhesives. The device is easy and quick to prepare before use, requires no fixed installation, and can be quickly placed at different testing locations to meet the requirements of timely on-site testing.

[0005] To achieve the above objectives, this utility model provides a device for detecting the positive tensile force of a reflector adhesive, including a base plate, on which four support columns are threadedly connected, and an upper top plate is installed on the top of each support column;

[0006] A nut is welded to the hole in the center of the top plate, and the lifting assembly passes through this nut and the hole.

[0007] The lifting assembly consists of a lifting screw and a handwheel. The bottom end of the lifting screw is connected to the electronic crane scale, and the lower end of the electronic crane scale is connected to the suspension joint.

[0008] The upper top plate has a fixing nut on its upper and lower parts. By tightening the fixing nuts, the upper top plate and the support column are stably connected, thereby ensuring that the upper surface of the upper top plate is in a horizontal state.

[0009] The multiple support columns are 300mm long and 12mm in diameter, with threads machined at both ends, and are respectively connected to the top plate and the bottom plate.

[0010] The lower part of the suspension joint has an open groove design.

[0011] A rubber sheet with a thickness of 5mm is bonded and fixed to the lower surface of the base plate.

[0012] This utility model discloses a device for testing the positive tensile force of a reflector adhesive. The finished reflector to be tested, after bonding, is placed on a horizontal inspection platform. An M6 bolt is installed into the threaded hole of the reflector adhesive. The device is then inserted from above into the adhesive through a circular hole in the base plate. The height of the electronic crane scale and suspension connector is adjusted by rotating the lifting assembly until the top nut of the M6 ​​bolt is properly connected to the suspension connector. The power switch of the electronic crane scale is turned on, and its reading is adjusted to "zero." The lifting assembly is then rotated clockwise at a uniform speed to move the electronic crane scale and suspension connector at a uniform and stable speed. Raise the scale until the M6 ​​bolts and the adhesive to the reflector are completely detached from the finished reflector. Observe the reading on the electronic crane scale. At this time, the reading on the electronic scale is in kilograms. Multiply the reading by 9.8 Newtons / kg. The result is the positive tensile force of the adhesive. Repeat the corresponding steps until the tensile force of all adhesives has been measured. Turn off the power switch of the electronic crane scale and store the device properly. This device is portable, flexible, small in size and light in weight, so the preparation work before use is convenient and quick. It does not require fixed installation and can be quickly placed in different testing locations to meet the requirements of timely on-site testing. Attached Figure Description

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

This utility model provides a device for detecting the positive tensile force of a reflector bond: including a base plate 7, a support column 4, an upper top plate 2, a lifting assembly 1, an electronic crane scale 5, and a suspension connector 6. The aforementioned solution allows for convenient and quick preparation before use, requires no fixed installation, and can be quickly placed at different testing locations to meet the requirements of timely on-site testing. It is understood that the aforementioned solution can be quickly placed at different testing locations to meet the requirements of timely on-site testing.

[0022] In this embodiment, the base plate 7 is used for mounting and supporting the working parts of the device.

[0023] The base plate 7 is threaded with four support columns 4, and an upper top plate 2 is installed on the top of the support columns 4; the upper top plate 2 is used for the lifting assembly 1.

[0024] A nut is welded to the hole in the center of the upper top plate 2, through which the lifting component 1 passes; the upper top plate 2 is made of 5mm steel plate with a specification of 150mm×100mm, and is connected to the bottom plate 7 by four support columns 4 to form the main structure of the device.

[0025] The lifting assembly 1 consists of a lifting screw and a handwheel. The bottom end of the lifting screw is connected to the electronic crane scale 5, and the lower end of the electronic crane scale 5 is connected to the suspension connector 6. The handwheel has a diameter of 100mm and is connected and fixed to the M16 lifting screw as a whole. The lifting screw is welded and fixed to the center of the upper top plate 2 and passes through the hole in the upper top plate 2, with its lower end connected to the electronic crane scale 5.

[0026] Secondly, each of the upper and lower parts of the top plate 2 has a fixing nut 3. By tightening the fixing nuts 3, the upper top plate 2 and the support column 4 are stably connected, thereby ensuring that the upper surface of the upper top plate 2 is in a horizontal state. This structure ensures that the upper top plate 2 can be installed quickly and stably. The fixing nut 3 is of specification M12, and its main function is to ensure a firm connection between the upper top plate 2 and the support column 4. It is installed on the threaded part at the top of the support column 4. There is one fixing nut 3 on each of the upper and lower parts of the upper top plate 2. By tightening the fixing nuts 3, the connection between the upper top plate 2 and the support column 4 is ensured to be firm, and the upper surface of the upper top plate 2 is guaranteed to be in a horizontal state.

[0027] Then, multiple support columns 4, each 300mm long and 12mm in diameter, are machined with threads at both ends and connected to the upper top plate 2 and the bottom plate 7, respectively. The support columns 4 and the upper top plate 2 are slidably connected, meaning that the externally threaded ends of the top of the support columns 4 can slide directly through the through holes on the upper top plate 2, and are then connected and assembled with fixing nuts 3.

[0028] Furthermore, the lower part of the suspension connector 6 has an open groove design. The suspension connector 6 is made of iron material, and its upper part is connected to the lower end of the electronic crane scale 5. The lower part adopts an "open groove design", the main purpose of which is to ensure a firm connection with the upper nut of the M6 ​​bolt 11 when measuring the tensile force of the adhesive.

[0029] Finally, a rubber sheet 8 with a thickness of 5mm is bonded and fixed to the lower surface of the base plate 7. Its main function is to protect the reflector when testing the tensile strength of the bonded material, preventing direct contact between the base plate 7 and the reflector, thus avoiding damage to the reflector.

[0030] When using the reflector adhesive positive tensile force testing device of this utility model, the first step is to place the finished reflector 9 to be tested after bonding on a horizontal inspection platform. The second step is to install the M6 ​​bolt 11 into the threaded hole of the reflector adhesive 10, and then insert the device from above the reflector adhesive 10 through the round hole of the base plate 7. The third step is to adjust the height of the electronic crane scale 5 and the suspension joint 6 by rotating the handwheel of the lifting assembly 1 to drive the lifting screw, until the top nut of the M6 ​​bolt 11 is properly connected to the suspension joint 6. The fourth step is to turn on the power switch of the electronic crane scale 5, adjust its reading to "zero", and rotate the handwheel of the lifting assembly 1 clockwise at a uniform speed to drive the lifting screw. The screw lowers, causing the electronic crane scale 5 and the suspension joint 6 to rise at a constant and stable speed until the M6 ​​bolt 11 and the reflector adhesive 10 are completely detached from the finished reflector 9. Fifth step: Observe the reading of the electronic crane scale 5. The reading is in kilograms. Multiply the reading by 9.8 Newtons / kg to obtain the positive tensile force of the adhesive. Sixth step: Repeat steps two through five until all adhesive tensile forces have been measured. Turn off the power switch of the electronic crane scale 5 and store the device properly. This device is portable, flexible, small in size, and lightweight, making preparation before use convenient and quick. It requires no fixed installation and can be quickly placed at different testing locations to meet the requirements of timely on-site testing.
