Description

Technical Field

[0001] This utility model belongs to the field of construction testing technology, specifically relating to a flatness measuring device for building construction. Background Technology

[0002] During construction, the flatness of the completed walls needs to be tested. The existing method involves pressing a measuring ruler against the wall and then visually observing the gap between the ruler and the wall. A feeler gauge is then used to measure the observed gap to determine if the wall's flatness meets the standards. However, this method has the following shortcomings: ① The gaps between the measuring ruler and the wall are mostly judged by human eyes, which is prone to misjudgment and omission and is extremely dependent on testing experience. ② Measuring the gaps in the recesses requires the use of a feeler gauge, which is inconvenient for measuring the gaps in the recesses.

[0003] Therefore, we propose a flatness measuring device for building construction. Utility Model Content

Detailed Implementation

[0014] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Example 1, like Figures 1 to 3 The flatness measuring device for building construction shown includes a strip 100, on which a transverse guide rail 101 is provided. A measuring mechanism is slidably connected to the transverse guide rail 101. The measuring mechanism includes: Slide cylinder 110 is slidably connected to transverse guide rail 101; A vertical slide rod 111 is slidably sleeved on the inner side of the slide cylinder 110 and passes through it vertically. A ball bearing 112 is installed at the lower end of the vertical slide rod 111 and a mounting block 113 is fixed at the top. Spring 114, vertical slide rod 111 and the top inner wall of slide cylinder 110 are elastically connected by spring 114; The strip 100 is detachably connected to the pins 102 on both sides of the horizontal direction. The mounting block 113 has a horizontal through-hole 115. The mounting block 113 has a pointer 116 on one side of the vertical direction. The pointer 116 is machined with scale lines 117. When the pin 102 is inserted into the socket 115, the spring 114 is compressed, making the ball bearing 112 flush with the lower end of the strip 100, and the 0 mark line of the scale 117 of the pointer 116 is flush with the upper end of the strip 100.

[0016] like Figures 1 to 2 Before using the device, adjustments are required, specifically: slide the measuring mechanism so that the slide cylinder 110 is at any end of the horizontal guide rail 101, then pull up the vertical slide rod 111 to compress the spring 114, and finally insert the pin 102 into the insertion hole 115 of the mounting block 113 so that the ball bearing 112 is flush with the lower end of the strip 100, and the 0 mark line of the scale 117 of the pointer 116 is flush with the upper end of the strip 100. When using the device to test the flatness of the wall, first press the adjusted device against the wall so that one side of the ball bearing 112 of the strip 100 is in close contact with the wall. Then remove the pin 102. Since the pin 102 is removed, the mounting block 113 is no longer locked. Then push the slide cylinder 110 along the horizontal guide rail 101 so that the ball bearing 112 rolls over it. When the ball bearing 112 passes through the concave part of the wall, the vertical slide rod 111 moves towards the wall under the rebound force of the spring 114. This causes the scale 117 on the pointer 116 of the mounting block 113 to change relative to the upper end face of the strip 100. People can then know the depth of the concave part of the wall and thus the flatness of the wall by observing the change in the scale 117.

[0017] This utility model's technical solution is an improvement on the existing measuring ruler. The measurement mechanism eliminates the need for human eyes to judge the concave area, and the depth of the concave area on the wall can be intuitively determined by the changes in the scale markings. It eliminates the need for feeler gauges and simplifies the workload of wall measurement.

[0018] As a further improvement to the technical solution in this embodiment, please refer to... Figures 1 to 3 The details are as follows: ① The slide 110 is also equipped with a push handle 118. By setting the push handle 118, people can easily push the slide 110, which is convenient for operation.

[0019] ② Both sides of the strip 100 are equipped with fixing mechanisms, which include: Mounting base 120, which is fixedly connected to the transverse side of strip 100; The screw 121 and the mounting base 120 are provided with a sliding hole that matches the screw 121, and the screw 121 is longitudinally slidably connected to the sliding hole; The lower limit block 122 is fixed to the lower end of the screw 121, and the lower limit block 122 is equipped with a suction cup 123. The limiting nut 124 is threadedly connected to the screw 121, and the mounting base 120 is located between the lower limiting block 122 and the limiting nut 124.

[0020] The fixing mechanism helps to secure the device to the wall. In use, the device is first attached to the wall by the suction cups 123 on both sides. Then, the user presses the strip 100 firmly against the wall. Finally, by screwing the limiting nut 124 down the screw 121, the strip 100 is clamped tightly by the combined action of the limiting nut 124 and the wall, thus freeing the user's hands from having to manually hold the strip 100. It should be noted that the suction cups 123 in the figure are only for example and their number is not limited. To ensure the suction effect, multiple suction cups can be set to improve the suction effect or suction cups with high suction capacity can be used. In addition, the wall needs to be cleaned before the suction cups 123 are attached to the wall to improve the suction effect and prevent them from falling off.

[0021] Example 2: This embodiment is based on Embodiment 1, and in order to enable the device to be folded and stored to reduce its floor space occupation, the following improvements are made: Figure 4 and Figure 5 As shown: The middle partition of the strip 100 is divided into two sections. The two sections of strip 100 are hinged together on one side by a hinge seat 200, and a locking component is provided on the other side of the two sections of strip 100.

[0022] The hinge 200 allows the two strips 100 to be unfolded during use and then locked in place using the locking assembly, presenting the following configuration: Figure 5 After being placed in its proper state, it can be used. When storing, it is flipped over using the hinge base 200, presenting the following appearance: Figure 4 This design significantly reduces space and makes it easier to carry.

[0023] Specifically, the locking component structure in this embodiment is as follows; please refer to [link / reference]. Figure 4 and Figure 5 The locking components include: Two clamping bolts 201 are threadedly connected to the adjacent ends of the two strip plates 100; The connecting piece 202 has a through hole on one side that matches the clamping bolt 201, and an opening 203 on the other side that matches the clamping bolt 201. One of the clamping bolts 201 passes through the through hole and clamps one side of the connecting piece 202, while the opening 203 on the other side of the connecting piece 202 matches and is clamped by another clamping bolt 201.

[0024] After the two strips 100 are unfolded, the two clamping bolts 201 are loosened, at which point the connecting piece 202 can move. Then, the connecting piece 202 is rotated so that the opening 203 of the connecting piece 202 hooks onto another clamping bolt 201. Then, the two clamping bolts 201 are tightened at the same time. In this way, the two sides of the connecting piece 202 are connected and fixed to the two strips 100 respectively, thus completing the unfolding and fixing of the strips 100. The structure is simple and easy to operate.

[0025] Specifically, in order to ensure that the 100mm folded panel can be secured, please refer to [link / reference needed]. Figure 4 and Figure 5 Each of the two strips 100, at its far end, is provided with a magnet 204, which is located on the longitudinal side corresponding to the hinge seat 200. After folding and storing, as... Figure 4 As shown, the two magnetic pieces 204 are close to each other. In order for the two magnetic pieces 204 to be magnetically attracted, the magnetic poles on the corresponding sides of the two magnetic pieces 204 are opposite. Thus, they can be folded and fixed by magnetic attraction. This design is simple in structure and easy to operate.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
