Description

Technical Field

[0001] This utility model belongs to the field of engineering surveying technology, and in particular relates to a vertical measuring ruler for building engineering. Background Technology

[0002] In building construction, the accurate verticality of the structure is a key element to ensure the safety of the building and compliance with design specifications. Therefore, it is necessary to use a verticality measuring ruler to check the verticality of the building, walls, columns and other structures.

[0003] The existing measuring rulers are not easy to store after use, which makes them inconvenient to carry. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical measuring ruler for building engineering, which solves the problem that existing measuring rulers are inconvenient to store after use, making them difficult to carry.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a vertical measuring ruler for building engineering, comprising a main ruler body, a connecting ruler, and a mating frame. The top end of the main ruler body is hinged to the bottom end of the connecting ruler. An extension ruler is slidably connected inside the connecting ruler. Several positioning holes are evenly distributed on one side of the extension ruler. A mating hole is provided on one side of the top end of the connecting ruler, and the mating hole corresponds to the positioning hole. The mating frame is U-shaped and is located on the periphery of the top end of the connecting ruler. A connecting plate is fixedly connected to one surface of the mating frame, and a positioning rod is fixedly connected to the bottom surface of the connecting plate. The positioning rod passes through the mating hole and is inserted into the positioning hole. A locking block is fixedly connected to one side of one end of the mating frame. A locking groove is provided on one side of the bottom end of the main ruler body, and the locking groove is adapted to the locking block and the mating frame.

[0007] Both sides of the top of the connecting ruler are fixedly connected to straight groove frames, and both inner sides of the mating frame are fixedly connected to sliding shafts. The sliding shafts are set inside the straight groove frames and slide in cooperation with the straight groove frames. A mating spring is installed between the inner top surface of the straight groove frame and the sliding shaft.

[0008] The bottom of the connecting ruler has grooves on both sides. A connecting spring is fixedly connected to the inner wall of the groove. A limit rod is fixedly connected to one end of the connecting spring. One end of the limit rod is set in the groove and slides with the groove. The other end is set on the outer side of the connecting ruler. An annular groove is formed on the circumferential side of the limit rod.

[0009] Limiting plates are hinged to both sides of the top of the main scale body. One end of the limiting plate has an arc-shaped groove, which matches the annular groove of the limiting rod. In the above structure, when using the measuring scale, the connecting scale and the main scale body are swung to be level, so that the bottom surface of the connecting scale is in contact with the top surface of the main scale body. Then, the limiting rod is pulled, and the limiting plate is swung to make the arc-shaped groove on the limiting plate engage with the annular groove on the limiting rod. The limiting rod is then released, and under the action of the connecting spring, the limiting rod clamps the limiting plate and the surface of the connecting scale, thereby fixing the connection between the connecting scale and the main scale body for easy use.

[0010] The inner bottom of the slot is provided with a limiting screw, and the inside of the card block is provided with a screw hole, and the limiting screw is threaded to the screw hole.

[0011] This utility model has the following beneficial effects:

[0012] This invention features a hinged main scale body and connecting scale. When not in use, the connecting scale is swung to bring its side against the side of the main scale body, causing one end of the mating frame and the locking block to engage in the slot. Tightening the limiting screw then connects it to the threaded hole on the locking block, facilitating the storage and unfolding of the measuring scale, and making it easy to carry. In use, pulling up the mating frame allows the sliding shaft to slide within the straight groove frame, compressing the mating spring. This, in turn, causes the positioning rod to disengage from the positioning hole via the connecting plate, allowing the extension scale to be pulled. This enables easy adjustment of the measuring scale's length for use in different construction environments.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] Please see Figures 1-5As shown, this utility model is a vertical measuring ruler for building engineering, including a main ruler body 1, a connecting ruler 2, and a matching frame 205. The top end of the main ruler body 1 is hinged to the bottom end of the connecting ruler 2. An extension ruler 201 is slidably connected inside the connecting ruler 2. Several positioning holes 202 are evenly distributed on one side of the extension ruler 201. A matching hole 204 is provided on one side of the top end of the connecting ruler 2. The matching hole 204 corresponds to the positioning hole 202. The matching frame 205 is U-shaped and is set on the periphery of the top end of the connecting ruler 2. A connecting plate 206 is fixedly connected to one surface of the matching frame 205. A positioning rod 207 is fixedly connected to the bottom surface of the connecting plate 206. The positioning rod 207 passes through the matching hole 204 and is inserted into the positioning hole 202. A locking block 208 is fixedly connected to one side of one end of the matching frame 205. A locking groove 101 is provided on one side of the bottom end of the main ruler body 1. The locking groove 101 is adapted to the locking block 208 and the matching frame 205.

[0026] Both sides of the top of the connecting ruler 2 are fixedly connected to a straight groove frame 209. Both sides of the mating frame 205 are fixedly connected to a sliding shaft 211. The sliding shaft 211 is set inside the straight groove frame 209 and slides in cooperation with the straight groove frame 209. A mating spring 210 is installed between the inner top surface of the straight groove frame 209 and the sliding shaft 211.

[0027] Grooves are provided on both sides of the bottom end of the connecting ruler 2. A connecting spring is fixedly connected to the inner wall of the groove. A limit rod 203 is fixedly connected to one end of the connecting spring. One end of the limit rod 203 is set in the groove and slides with the groove. The other end is set on the outer side of the connecting ruler 2. An annular groove is provided on the circumferential side of the limit rod 203.

[0028] Limiting plates 102 are hinged to both sides of the top of the main scale body 1. One end of the limiting plate 102 has an arc-shaped groove, which is adapted to the annular groove of the limiting rod 203. In the above structure, when using the measuring scale, the connecting ruler 2 is swung to be level with the main scale body 1, so that the bottom surface of the connecting ruler 2 is in contact with the top surface of the main scale body 1. Then, the limiting rod 203 is pulled, and the limiting plate 102 is swung again, so that the arc-shaped groove on the limiting plate 102 and the annular groove on the limiting rod 203 are engaged. When the limiting rod 203 is released, under the action of the connecting spring, the limiting rod 203 clamps the limiting plate 102 and the surface of the connecting ruler 2, thereby fixing the connection between the connecting ruler 2 and the main scale body 1, which is convenient for use.

[0029] The inner bottom of the slot 101 is provided with a limiting screw 103, and the inside of the block 208 is provided with a screw hole 212, and the limiting screw 103 is threadedly matched with the screw hole 212.

[0030] It should be further noted that the measuring ruler consisting of the main ruler body 1, the connecting ruler 2, and the extension ruler 201 is existing technology and possesses the existing measuring structure. This is readily understood by those skilled in the art, and will not be elaborated further. Compared to existing technologies, this invention improves the storage and portability of the measuring ruler, while also facilitating adjustment of its operating length. In actual use, tightening the limiting screw 103 releases its restriction on the screw hole 212, allowing the connecting ruler 2 to be pulled and swung to align with the main ruler body 1, so that the bottom surface of the connecting ruler 2 is in contact with the top surface of the main ruler body 1. Then, pulling the limiting rod 203 and swinging the limiting plate 102 causes the arc groove on the limiting plate 102 to engage with the annular groove on the limiting rod 203. Releasing the limiting rod 203 allows the connecting spring to clamp the limiting plate 102 and the surface of the connecting ruler 2, thus fixing the connection between the connecting ruler 2 and the main ruler body 1 for easy use. Pulling up the mating bracket 205 allows the sliding shaft 211 to slide within the straight groove bracket 209, compressing the mating spring 210. The connecting plate 206 drives the positioning rod 207 to disengage from the positioning hole 202, thereby pulling the extension ruler 201. This allows for easy adjustment of the length of the measuring ruler to suit different construction environments. After use, the extension ruler 201 is retracted into the connecting ruler 2. Then, the limiting rod 203 is pulled to move the limiting plate 102 away, allowing the connecting ruler 2 to swing so that its side is against the side of the main ruler body 1. One end of the mating frame 205 and the locking block 208 are then engaged in the locking groove 101. Finally, the limiting screw 103 is tightened to connect with the screw hole 212 on the locking block 208, facilitating the storage and unfolding of the measuring ruler and making it easy to carry.
