DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] See also Figure 1 and Figure 2 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: a detection device for road and bridge engineering supervision, comprising

[0020] A ruler body 1, a fixed ruler bar 2 welded and fixed on the left side surface of the ruler body 1, a vernier ruler bar 3 arranged on the left side surface of the ruler body 1 and corresponding to the position of the fixed ruler bar 2, a strip-shaped main slide groove 11 opened on the surface of the ruler body 1, a vernier ruler seat 4 slidably arranged inside the strip-shaped main slide groove 11, a strip-shaped side slide groove 12 opened on the left side surface of the ruler body 1 and communicating with the strip-shaped main slide groove 11, a strip-shaped connecting block 32 welded and fixed on the right side surface of the vernier ruler bar 3 and slidably located inside the strip-shaped side slide groove 12, and the right end of the strip-shaped connecting block 32 is welded and fixed to the vernier ruler seat 4;

[0021] The quick lock mechanism includes an inner slide groove 57 provided inside the sliding ruler seat 4, an inner slider 58 and a spring 59 arranged inside the inner slide groove 57, a connecting rod 510 welded and fixed to the bottom surface of the inner slider 58 and extending through the bottom of the ruler body 1, a movable bottom plate 54 welded and fixed to the bottom surface of the connecting rod 510, a pressing block 51 welded and fixed to the top surface of the inner slider 58 and extending through the top of the ruler body 1, and two anti-slip strips 56 glued and installed on the bottom surface of the ruler body 1. The two ends of the movable bottom plate 54 extend to the two sides of the bottom of the ruler body 1 respectively, and the tops of the two ends of the movable bottom plate 54 are glued and fixed with anti-slip strips 55 tightly pressed against the anti-slip strips 56. The anti-slip strips 56 and the anti-slip slide 55 are both made of rubber material. The top surface of the anti-slip slide 55 is provided with a plurality of strip anti-slip protrusions A, and the bottom surface of the anti-slip strip 56 is provided with a plurality of strip anti-slip protrusions B, so as to increase the friction between the anti-slip strip 56 and the anti-slip slide 55.

[0022] The top end of the spring 59 abuts against the bottom surface of the inner sliding block 58 , and the bottom end of the spring 59 abuts against the bottom inner wall of the inner sliding groove 57 .

[0023] A pressing plate 53 is welded and fixed to the top of the pressing block 51 , and a rubber top pad 52 is installed on the top surface of the pressing plate 53 , which can facilitate subsequent operators to press down the pressing block 51 .

[0024] Among them, an indicator strip 31 is welded and fixed on the top surface of the vernier bar 3, and a scale corresponding to the indicator strip 31 is provided on the left surface of the ruler body 1 relative to the top of the strip-shaped side slide groove 12. Subsequently, the two steel bars to be measured can be placed between the vernier bar 3 and the fixed scale bar 2, and then the vernier bar 3 can be slid to fit the steel bars to be measured by sliding. At this time, the spacing between the two steel bars can be judged by the scale pointed to by the indicator strip 31. A handle 6 is fixed on the bottom surface of the ruler body 1 to facilitate subsequent gripping.

[0025] In summary, in actual use, when the operator needs to move the sliding scale bar 3 to detect the spacing of the steel bars at the construction site of the road and bridge project, he only needs to press the rubber top pad 52, so that the pressing block 51 moves the inner sliding block 58 downward, and compresses the spring 59, so that the connecting rod 510 moves the movable bottom plate 54 downward smoothly, so that the anti-sliding block 55 and the anti-slip strip 56 are separated, and the limit of the sliding scale seat 4 can be released. At this time, the sliding scale bar 3 can be slid on the side of the scale body 1. When the sliding scale bar 3 slides to a suitable position, the operator only needs to release the pressing block 51, and push the inner sliding block 58 back and reset under the push of the spring 59, and move the connecting rod 510 with the movable bottom plate 54 upward, finally making the anti-sliding block 55 fit tightly with the anti-slip strip 56 again, and the sliding scale bar 3 can be locked again after sliding. Because the sliding scale bar 3 has a light weight, the friction between the two anti-sliding blocks 55 and the two anti-slip strips 56 can fully achieve stable limit.

[0026] Example 2

[0027] See also Figures 1 to 3 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the subsequent disassembly and replacement of the rubber top pad 52 can be facilitated by the provided disassembly and assembly structure.

[0028] Specifically, a disassembly structure is provided between the rubber top pad 52 and the pressure plate 53, and the disassembly structure includes two rubber plugs 521 arranged on the bottom surface of the rubber top pad 52, a side clamping block 522 arranged on the bottom end surface of the rubber plug 521, and two plug holes 531 opened on the surface of the pressure plate 53. The plug holes 531 correspond to the positions of the rubber plugs 521. The bottom end of the rubber plug 521 passes through the plug holes 531 to the bottom of the pressure plate 53, and the side clamping block 522 is clamped on the bottom surface of the pressure plate 53. The rubber plug 521 and the side clamp block 522 are an integrated structure, both of which are made of rubber material and will undergo elastic deformation when squeezed. If the rubber top pad 52 needs to be removed for replacement later, the rubber top pad 52 only needs to be lifted up with force so that the rubber plug 521 and the side clamp block 522 are squeezed and elastically deformed, and finally the side clamp block 522 and the rubber plug 521 are pulled out of the socket 531, and the rubber top pad 52 can be successfully removed for replacement.

[0029] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
