Description

Technical Field

[0001] This utility model relates to the field of floor testing, specifically to a floor locking force testing device. Background Technology

[0002] The floor locking force test is to ensure the connection strength and stability of the floor joints, prevent loosening or falling off during use, and ensure the durability and safety of the floor.

[0003] The locking force test primarily assesses the mechanical connection strength at the joints of the flooring, simulating the tensile and shear forces that the flooring may experience in actual use. Insufficient locking force may lead to cracking at the joints, loosening of the joints, or even displacement or damage to the flooring due to external forces during long-term use, affecting the overall structural stability.

[0004] The locking force between click-lock floorboards is mostly tested using a horizontal tensile testing machine. This machine includes a worktable, two clamps mounted on the worktable, a linear drive mechanism to move the clamps, and a force sensor to measure the horizontal tension. After the product to be tested is placed on the clamps, the operator operates the clamps to secure the product. Once secured, the locking force of the floorboard is tested. However, this horizontal tensile testing machine has the following problems:

[0005] Due to the precision issues of the tongue and groove joints on the two floorboards, for example, after the tongue and groove joints of the two floorboards are engaged, the floorboards will be in an unbalanced position with one end higher than the other. Since the depth of the tongue and groove joints themselves is limited, it is usually difficult to detect with the naked eye. When the linear drive mechanism moves the fixture, the floorboards are subjected to tension. Because the two floorboards are engaged with one end higher than the other, the force on the fixture is unbalanced. One end of the tension sensor is fixed to the fixture with a screw, and the other end is fixed to the worktable with a screw. Therefore, when the force on the fixture is unbalanced, it will cause the tension sensor to rotate or twist. In this case, on the one hand, it will cause inaccurate locking force testing, and on the other hand, it may damage the tension sensor.

[0006] In addition, the linear drive mechanism mentioned above generally uses a motor as the driver, and the output end of the motor is connected to a reducer. The reducer generally consists of a pair of bevel gears, and the axial directions of the two bevel gears form a 90-degree angle. Therefore, the output end of the motor and the output end of the reducer form a 90-degree angle. This type of linear drive mechanism may occupy a lot of space in some places, so it is not suitable. Utility Model Content

[0007] This invention provides a floor locking force detection device, which can prevent the tension sensor from being subjected to torque during operation.

[0008] The technical solutions to the above technical problems are as follows:

[0009] A floor latching force detection device includes a worktable, a linear drive mechanism, a first guide assembly, a first clamp, a support plate, a tension sensor, and a second clamp. The linear drive mechanism and the first guide assembly are respectively mounted on the worktable. The first clamp is connected to the linear drive mechanism and is slidably engaged with the first guide assembly. The support plate is fixed to the worktable, and the linear drive mechanism is also rotatably engaged with the support plate. One end of the tension sensor is fixed to the support plate, and the other end of the tension sensor is fixed to the second clamp. The device is characterized by further including a second guide assembly that guides the second clamp to move in a linear direction to avoid torque on the tension sensor. The second guide assembly is fixed to the worktable, passes through the second clamp, and is slidably engaged with the second clamp.

[0010] In this invention, a second guide component is added. When the two floorboards are fitted together, the floorboards may be tilted at one end due to insufficient precision. When the linear drive mechanism applies a pulling force to the floorboards, the second guide component is fixed to the worktable, and the second clamp is slidably fitted with the second guide component. This ensures that the second clamp can only move in a straight line. Even if the forces at both ends of the second clamp are unbalanced, the second clamp will not twist, thus preventing the tension sensor from being subjected to torque. Attached Figure Description
