Description

Technical Field

[0001] This utility model belongs to the technical field of testing devices, and in particular relates to a flatness testing device. Background Technology

[0002] Wall flatness inspection is one of the items in house inspection, and wall flatness testing devices are essential tools. Traditional testing devices require ladders to reach high walls for measurement, especially when measuring multiple areas. This process is cumbersome, increases workload, and is mostly done manually, leading to significant errors. Therefore, height-adjustable wall flatness testing devices have emerged. While these devices allow for testing of higher wall areas, they also have drawbacks. For example, when testing higher walls, the angle is difficult to adjust after the device is raised, requiring it to be lowered, adjusted, and then raised again, making the operation cumbersome and time-consuming.

[0003] Patent document CN222026677U discloses a wall flatness detection device, including a base, a mounting rod, and a support plate. The base has a lifting assembly for adjusting the height of the support plate, the support plate has a mounting frame, and the mounting rod is rotatably connected to the mounting frame. The mounting frame has a positioning assembly for fixing the angle of the mounting rod, the mounting rod has a slidable mounting part, and the mounting rod has a moving mechanism for driving the mounting part to move. The mounting part has a sliding rod, a spring a connects the end of the sliding rod and the mounting part, the end of the sliding rod has a displacement sensor, and the end of the sliding rod away from the mounting part has a rotatable roller. In this device, the moving mechanism drives the mounting part to move on the mounting rod, the roller rolls on the wall surface, and the displacement of the sliding rod on the mounting part is detected and recorded by the sensor. The angle of the mounting rod is adjustable, and detection is performed in both horizontal and vertical directions. However, this device lacks the force to apply pressure to one side of the detection structure on the wall surface, which may affect the accuracy of flatness detection when the ground is uneven.

[0004] Patent document CN217303868U discloses a building wall flatness detection device, including a base plate with a mounting box on it. A fixing plate is fixedly connected to the left end of the mounting box, and an infrared sensor is mounted on the fixing plate. A control panel is installed at the front end of the mounting box, and the control panel is electrically connected to the infrared sensor. When the device encounters a protruding wall surface, the guide wheel moves to the left, and the sliding rod also moves to the left. When it encounters a concave wall surface, the guide wheel is reset by the elastic action of a spring, thereby driving the sliding rod to move. The left and right movement of the sliding rod is detected by the infrared sensor, and the detection result is displayed on the control panel to determine the flatness of the wall surface. However, this device requires the detection of an electronic infrared sensor and height adjustment via an electric telescopic rod, thus requiring electricity for operation. Utility Model Content

[0024] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0025] Example:

[0026] like Figures 1 to 5 As shown, a flatness detection device includes a support mechanism 100 and a contact plate 200. The support mechanism 100 includes a rotating component 101, a locking component 102, a moving component 103, and a connecting component 104. The rotating component 101 is connected to the contact plate 200 through the connecting component 104. The locking component 102 is connected to the rotating component 101. The rotating component 101 is disposed on the moving component 103.

[0027] The rotating assembly 101 includes a turntable 101a, a round rod 101b, a pulley 101c, a collar 101e, and a support assembly. One end of the turntable 101a is connected to the connecting assembly 104, and the other end of the turntable 101a is connected to one end of the round rod 101b. The other end of the round rod 101b passes through the collar 101e and is connected to the pulley 101c. The collar 101e is coaxially sleeved on the outside of the round rod 101b. A pull rope 101d is provided on the pulley 101c. A bearing is provided inside the collar 101e. The collar 101e is rotatably connected to the round rod 101b. The collar 101e is connected to the support assembly. The support assembly is connected to the locking assembly 102 and the moving assembly 103.

[0028] The support assembly includes an inner rod 101f and a sleeve 101g. One end of the inner rod 101f is connected to a collar 101e, and the other end of the inner rod 101f is slidably connected to the sleeve 101g by extending into the sleeve 101g through one end. The other end of the sleeve 101g is connected to a moving assembly 103. The sleeve 101g is provided with a screw hole and a positioning bolt 101h. The positioning bolt 101h passes through one side of the sleeve 101g through the screw hole. The inner rod 101f and the sleeve 101g at its lower end form a telescopic rod structure for adjusting the detection height of the contact plate 200. After adjustment, it is locked by the positioning bolt 101h.

[0029] The contact plate 200 is specifically a rectangular plate. The outer end face of the contact plate 200 is horizontal and protrudes outside the turntable 101a. During testing, the outer end face of the contact plate 200 abuts against the wall surface, and the gap between the contact plate 200 and the wall surface is observed to determine the flatness of the wall surface. The upper end of the pull rope 101d is sleeved on the pulley 101c. Pulling the pull rope 101d drives the pulley 101c to rotate. The pulley 101c is fixed to the end of the round rod 101b away from the turntable 101a. The rotation of the pulley 101c drives the round rod 101b to rotate, which in turn drives the turntable 101a at the other end of the round rod 101b to rotate. The contact plate 200 rotates with the turntable 101a to adjust different testing angles. After adjustment, it is locked by the locking assembly 102.

[0030] The sleeve 101g has a vertically arranged strip hole 102g on its side wall, and the operating rod 102f passes through the strip hole 102g and extends to the outside of the sleeve 101g.

[0031] The locking assembly 102 includes a mounting cavity 102a, a vertical rod 102b, an arc-shaped plate 102c, a slider 102d, and a first spring 102e. The mounting cavity 102a extends from the bottom end of the inner rod 101f to the inner ring surface of the collar 101e. The vertical rod 102b and the arc-shaped plate 102c are both disposed in the mounting cavity 102a. The top end of the vertical rod 102b is connected to the arc-shaped plate 102c, and the bottom end of the vertical rod 102b is connected to the top end of the slider 102d. The bottom end of the slider 102d is connected to the first spring 102e. The arc-shaped plate 102c and the side of the round rod 101b are adapted to each other. The slider 102d and the first spring 102e are both placed inside the sleeve 101g. An operating rod 102f is provided on the side wall of the slider 102d.

[0032] The concave surface of the arc-shaped plate 102c is a rough surface.

[0033] The locking assembly 102 is used to lock the round rod 101b to restrict its rotation after the abutment plate 200 is adjusted to a suitable angle, thereby restricting the rotation of the abutment plate 200. Specifically, the first spring 102e presses the slider 102d upward, and the slider 102d presses the vertical rod 102b upward, so that the arc plate 102c at the upper end of the vertical rod 102b is tightly pressed against the side wall of the round rod 101b, restricting the rotation of the round rod 101b. When it is necessary to adjust the angle of the abutment plate 200, the operating lever 102f is held and pulled downward, which drives the slider 102d and the vertical rod 102b to move downward, thereby causing the arc plate 102c to disengage from the round rod 101b, releasing the restriction on the rotation of the round rod 101b. After the adjustment is completed, the operating lever 102f is released, the spring force is released, and the arc plate 102c is pressed back onto the round rod 101b for locking.

[0034] Usage: Pull the inner rod 101f upward to move the contact plate 200 upward to the detection height, tighten the positioning bolt 101h to lock the height of the contact plate 200; pull down the operating rod 102f, pull the pull rope 101d to rotate the contact plate 200 to the detection angle, release the operating rod 102f to lock the detection angle of the contact plate 200.

[0035] When the device is raised for testing, the detection angle of the contact plate 200 can be adjusted by rotating component 101, eliminating the need to lower the device for adjustment. This makes adjustment convenient, and rotating component 101 is a mechanical transmission adjustment that does not rely on electric equipment.

[0036] The moving component 103 includes a slide 103a and a base 103b. The slide 103a is mounted on the base 103b, and the sleeve 101g of the support mechanism 100 is mounted on the slide 103a. A handrail 103c is provided on one side of the base 103b, and a wheel 103d is provided at the lower end of the base 103b. The base 103b provides support for the entire device, and the wheel 103d at the lower part of the base 103b facilitates the movement of the entire device.

[0037] The upper surface of the slide block 103a is provided with a sliding groove 103e and a guide rod 103f. The guide rod 103f is disposed within the sliding groove 103e and is arranged parallel to the round rod 101b. The guide rod 103f slides through the slide block 103a. A second spring 103g is disposed within the sliding groove 103e. One end of the second spring 103g is connected to the slide block 103a, and the other end of the second spring 103g is connected to the inner wall of the sliding groove 103e. The second spring 103g compresses the slide block 103a, causing the slide block 103a to move towards the wall, ensuring that the contact plate 200 always remains in contact with the wall.

[0038] The base 103b is provided with a positioning hole 103h, and a positioning pin 103i is provided on the positioning hole 103h. When the device is not in use, the positioning pin 103i is inserted into the positioning hole 103h to restrict the sliding of the slide 103a and ensure the stability of the entire device.

[0039] Usage: Push the handle 103c to move the device to the detection wall, adjust the detection height and angle and lock them. Then continue to push the handle 103c to move the device closer to the wall. After the contact plate 200 is against the wall, hold the handle 103c to prevent the entire device from moving. Observe the gap between the contact plate 200 and the wall to determine the flatness of the wall. During the detection process, due to the compression of the second spring 103g, the base 103b has a certain buffer margin. Even if the base 103b is moved slightly away from the wall by external force, the compression of the second spring 103g can ensure that the contact plate 200 is against the wall, ensuring the stability and accuracy of the detection.

[0040] The connecting component 104 includes a slot 104a, a first magnet block 104b, a second magnet block 104c, a limiting groove 104d, and a limiting post 104e. The slot 104a and the limiting groove 104d are disposed on the turntable 101a of the rotating component 101. The first magnet block 104b is disposed in the slot 104a. The limiting groove 104d and the limiting post 104e are slidably connected. The second magnet block 104c and the limiting post 104e are disposed on the contact plate 200.

[0041] Usage: The contact plate 200 is detachably fixed to the slot 104a of the turntable 101a by magnetic adsorption, which is convenient for disassembly and assembly. When not in use, the contact plate 200 can be directly removed, which helps to stabilize the device. The limiting groove 104d and the limiting post 104e cooperate to support the contact plate 200 when it is in vertical detection, preventing the contact plate 200 from falling off the slide 103e due to gravity.
