Description

Technical Field

[0001] This utility model belongs to the field of engineering testing technology, specifically relating to a building wall thickness testing device. Background Technology

[0002] During the construction process, in order to determine whether the completed wall meets the design requirements, it is necessary to test the thickness of the wall to ensure the safety and stability of the building structure.

[0003] Chinese patent CN221198267U discloses a wall thickness detection device for building engineering, including a handle and a long ruler. The long ruler is fixedly connected to the right side of the handle, and a baffle is fixedly connected to the right end of the long ruler. A limit rod is fixedly installed on the upper end of the side adjacent to the handle and the baffle. A spring is fixedly installed on the upper left side of the baffle, and a movable clamp is fixedly connected to the left end of the spring. A fixed clamp is fixedly connected to the right side of the handle. In this scheme, before measurement, the movable clamp is slid towards the baffle to make the spring elastic. Then, the movable clamp and the fixed clamp are moved to both sides of the wall. Then, the movable clamp is released, and the spring rebounds to push the movable clamp forward until the movable clamp and the fixed clamp clamp clamp the wall. Then, the scale line between the movable clamp and the fixed clamp is observed to know the wall thickness, thus completing the measurement of the wall thickness.

[0004] Regarding the above solution, some workers first push the movable clamp away from the fixed clamp by hand, then release the movable clamp directly and use the spring force to push the movable clamp towards the wall, clamping it with the fixed clamp on both sides of the wall. During this process, the movable clamp moves and contacts the wall at a relatively fast speed, making it prone to deformation due to collision with the wall, resulting in a short service life for the above solution. Utility Model Content

[0005] The present invention aims to provide a building wall thickness detection device to solve the problem of short service life of the above-mentioned solutions.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wall thickness detection device includes a fixed rod, a movable rod, a clamping mechanism, and a measuring ruler. One end of the fixed rod is fixedly connected to a crossbar. One end of the movable rod has a recessed groove, and the other end of the fixed rod is slidably inserted into the groove. A pin is fixedly mounted on the top of one end of the movable rod, and two first connecting rods are rotatably sleeved around the pin. One end of each of the two first connecting rods is located on either side of the movable rod. The clamping mechanism includes two clamping plates, which are slidably sleeved on the crossbar on both sides of the fixed rod. The tops of the two clamping plates are rotatably connected to second connecting rods, and one end of each of the two second connecting rods is rotatably connected to the middle of the second connecting rod on the same side. The top of one clamping plate is fixedly connected to one end of the measuring ruler, and the top of the other clamping plate slidably abuts against the measuring ruler. The length direction of the measuring ruler is parallel to the length direction of the crossbar.

[0008] The principle and effects of this technical solution:

[0009] Initially, the two clamping plates are located at both ends of the crossbar, and there is a gap between the fixed rod and the end wall of the sliding groove. In use, the side of the crossbar away from the fixed rod is brought into contact with the end wall of the wall. Then, the movable rod is slid so that one end of the movable rod is close to the crossbar. During this process, the two first connecting rods rotate, which in turn drives the two second connecting rods to rotate. At the same time, the two clamping plates move closer to each other as the second connecting rods rotate, until the side of the two clamping plates that are close to each other is in contact with the two side walls of the wall. At this point, the movable rod can no longer move. The distance between the side walls of the two clamping plates facing each other is read by observing the measuring ruler, and the thickness of the wall is then measured.

[0010] With the above setup, the movable rod is used to clamp the two clamps to the wall. When the clamps come into contact with the wall, the operator can immediately stop moving the movable rod to avoid the wall exerting a large reaction force on the clamps, thereby preventing the clamps from deforming due to collision with the wall and extending the service life of the device.

[0011] In this invention, the clamping mechanism further includes a spring, which is disposed within the slide groove and connected to the fixed rod and the end wall of the slide groove. Through this arrangement, when the movable rod slides towards the crossbar, the spring is compressed, giving it elasticity. This allows the spring to push the fixed rod away from the movable rod after the detection is completed and the crossbar is disengaged from the wall, thereby resetting the two clamping plates and preventing the fixed rod from dislodging from the slide groove.

[0012] In this invention, a gate-shaped limiting sleeve is fixedly provided on the top of the other clamping plate, and the measuring ruler slides through the channel formed by the limiting sleeve and the top of the other clamping plate. This arrangement limits the measuring ruler, ensuring that its length is always parallel to the length of the crossbar, thus improving the accuracy of the measurement results.

[0013] In this invention, the two clamping plates are symmetrically recessed with grooves on opposite sides, one end of which extends through to the side wall of the clamping plate away from the crossbar. A movable plate is slidably embedded within the groove. This design expands the measurement range of the device and improves its practicality.

[0014] In this invention, the two movable plates each have a groove on their opposite sides along a transverse direction, and the two clamping plates each have a through screw hole aligned with the groove on their opposite sides, with a bolt threaded through the screw hole. With this arrangement, after the movable plate is slid to a suitable position, rotating the bolt causes one end of the bolt to extend into the groove and press against the sidewall of the groove, thereby fixing the movable plate.

[0015] In this invention, a handle is fixedly provided vertically at the bottom of the movable rod. This design facilitates the gripping of the movable rod by the operator, improving the practicality of the device.

[0016] In this invention, a limiting strip is fixedly provided at the top of the fixed rod in a direction parallel to its axis, and a limiting groove is recessed on the inner sidewall of the sliding groove to cooperate with the limiting strip, with the limiting strip slidably embedded in the limiting groove. This design prevents the movable rod from rotating relative to the fixed rod during sliding, thereby preventing the application of torque to the first and second connecting rods and improving the smoothness of the device during operation.

[0017] In this invention, baffles are fixedly installed at both ends of the crossbar. This design prevents the two clamps from detaching from the crossbar, thus improving the practicality of the device. Attached Figure Description

One end of the fixed rod 10 is fixedly connected to a crossbar 11. One end of the movable rod 20 is recessed with a groove 21, and the other end of the fixed rod 10 is slidably inserted into the groove 21. A round pin 22 is fixedly installed at the top of one end of the movable rod 20. Two first connecting rods 221 are rotatably sleeved around the round pin 22, with one end of each of the two first connecting rods 221 located on opposite sides of the movable rod 20. The clamping mechanism includes a clamping plate 31. The clamping plates 31 are configured as two pieces, and are slidably sleeved on the crossbar 11 on both sides of the fixing rod 10. The tops of the two clamping plates 31 are respectively rotatably connected to the second connecting rods 311. One end of the two second connecting rods 311 is rotatably connected, and one end of the two first connecting rods 221 is rotatably connected to the middle of the second connecting rods 311 on the same side. The top of one clamping plate 31 is fixedly connected to one end of the measuring ruler 40, and the top of the other clamping plate 31 is slidably abutting against the measuring ruler 40. The length direction of the measuring ruler 40 is parallel to the length direction of the crossbar 11.

[0026] In this embodiment, the clamping mechanism further includes a spring 32, which is disposed in the slide groove 21 and is connected to the fixing rod 10 and the end wall of the slide groove 21 respectively.

[0027] In this embodiment, a door-shaped limiting sleeve 312 is fixedly provided on the top of another clamping plate 31. The measuring ruler 40 slides through the channel formed by the limiting sleeve 312 and the top of the other clamping plate 31. The side walls of the two clamping plates 31 facing each other are coplanar with the actual scale of the measuring ruler 40 and one side wall of the limiting sleeve 312.

[0028] In this embodiment, the two clamping plates 31 are respectively symmetrically recessed with slots 313 on opposite sides. One end of the slot 313 extends to the side wall of the clamping plate 31 away from the crossbar 11, and a movable plate 33 is slidably embedded in the slot 313.

[0029] In this embodiment, the two movable plates 33 are respectively provided with grooves 331 in the transverse direction on opposite sides, and the two clamping plates 31 are respectively provided with through screw holes 314 aligned with the grooves 331 on opposite sides, and bolts 34 are threaded through the screw holes 314.

[0030] In this embodiment, a handle 23 is fixedly provided vertically at the bottom of the movable rod 20.

[0031] In this embodiment, a limiting strip 12 is fixedly provided on the top of the fixed rod 10 in a direction parallel to its axis, and a limiting groove 211 that cooperates with the limiting strip 12 is recessed on the inner side wall of the sliding groove 21, and the limiting strip 12 is slidably embedded in the limiting groove 211.

[0032] In this embodiment, baffles 111 are fixedly provided at both ends of the crossbar 11.

[0033] The specific implementation process is as follows:

[0034] In the initial state, the two clamping plates 31 are located at both ends of the crossbar 11, and there is a gap between the fixed rod 10 and the end wall of the sliding groove 21. In use, the side wall of the crossbar 11 away from the fixed rod 10 is brought into contact with the end wall of the wall. Then, the movable rod 20 is slid so that one end of the movable rod 20 is close to the crossbar 11. During this process, the two first connecting rods 221 rotate, which in turn drives the two second connecting rods 311 to rotate. At the same time, the two clamping plates 31 move closer to each other as the second connecting rods 311 rotate, until the side of the two clamping plates 31 that are close to each other is in contact with the two side walls of the wall. At this time, the movable rod 20 can no longer move. The distance between the side walls of the two clamping plates 31 facing each other is read by observing the measuring ruler 40, and then the thickness of the wall is detected.
