Description

Technical Field

[0001] This utility model relates to the field of engineering surveying technology, specifically to a portable engineering surveying ruler. Background Technology

[0002] Portable measuring tapes are convenient tools for on-site engineering surveying, typically used for quickly measuring short distances or small dimensions. They are lightweight and portable, making them suitable for various engineering surveying tasks, especially when it is necessary to quickly obtain or compare dimensions on-site.

[0003] A patent with publication number CN218673410U proposes a portable measuring ruler for engineering supervision. When the device needs to mark the measurement location, pushing the marker moves the sliding block. When the sliding block moves horizontally on the outer wall of the sliding rod, the marker can move horizontally. After the marker moves to one side of the location to be marked, it pushes the rod to move. The movement of the rod moves the marking head. After one end of the marking head moves to the marking location, it can leave a marking mark at the marking location, eliminating the need to use other tools to mark the detection location, thus achieving the purpose of auxiliary marking of the location to be detected.

[0004] However, the ruler of the device is of a fixed length and cannot be extended according to the length of the object being measured, which limits the measuring length of the ruler. Utility Model Content

[0005] The purpose of this invention is to provide a portable engineering measuring ruler to solve the problem that existing devices cannot extend according to the length of the object being measured, thus limiting the measuring length of the ruler.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable engineering measuring ruler, comprising a first ruler body, a first limiting groove formed on the inner wall of the bottom end of the first ruler body, a second ruler body slidably disposed inside the first limiting groove, graduation lines fixedly disposed on the upper ends of both the first and second ruler bodies, a second limiting groove formed on the upper end of the second ruler body, a sliding groove formed on the upper end of the first ruler body, and an adapter structure slidably disposed inside the second limiting groove, the adapter structure comprising an adapter marking rod slidably disposed inside the second limiting groove, the upper end of the adapter marking rod passing through the sliding groove and a marking plate fixedly disposed at the rear end.

[0007] Preferably, a sealing cap is fixedly provided on one side of the second ruler body, and a screw is fixedly provided on one side of the front end of the sealing cap. The output end of the screw passes through the protrusion on one side of the front end of the first ruler body and a nut is provided on the outer wall thread.

[0008] Preferably, sealing gaskets are fixedly provided on the inner walls of both the front and rear ends of the sealing cap.

[0009] Preferably, a steel sheet is fixedly provided on one side of the second ruler body, and a magnetic suction plate is fixedly provided on the side wall of the first ruler body located on one side of the steel sheet.

[0010] Preferably, a damping pad is fixedly installed at the lower end of the marking plate, and the damping pad is made of rubber.

[0011] Preferably, a lever is fixedly provided at the upper end of the marking plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) By setting an adapter structure, after the second ruler body extends, the position marked on the second toothed plate can still be marked by sliding the adapter mark rod, thus achieving the purpose of marking two ruler bodies with one adapter mark plate.

[0014] 2) By setting a sealing cap, screw, and nut, the second ruler can be stored inside the first ruler, and one side of the second ruler can be shielded and protected to prevent damage to one side of the second ruler. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Combination Figures 1-5 A portable engineering measuring ruler for engineering surveying includes a first ruler body 1. A first limiting groove 3 is provided on the inner wall of the bottom end of the first ruler body 1. A second ruler body 4 is slidably arranged inside the first limiting groove 3. Scale lines 2 are fixedly provided on the upper ends of both the first ruler body 1 and the second ruler body 4. A second limiting groove 5 is provided on the upper end of the second ruler body 4. A sliding groove 8 is provided on the upper end of the first ruler body 1. An adapter structure 6 is slidably arranged inside the second limiting groove 5. The adapter structure 6 includes an adapter marking rod 7 slidably arranged inside the second limiting groove 5. The upper end of the adapter marking rod 7 passes through the sliding groove 8 and a marking plate is fixedly arranged at its rear end.

[0024] See Figure 2 and Figure 5 Furthermore, it is found that sealing gaskets 15 are fixedly installed on the inner walls of the front and rear ends of the sealing cover 12, a steel sheet 11 is fixedly installed on one side of the second ruler 4, a magnetic suction plate 10 is fixedly installed on the side wall of the first ruler 1 located on the side of the steel sheet 11, a damping pad 9 is fixedly installed at the lower end of the marking plate, the damping pad 9 is made of rubber, and a paddle is fixedly installed at the upper end of the marking plate.

[0025] Specifically, the sealing gasket 15 is used to ensure that the inner walls of the front and rear ends of the sealing cap 12 are in contact with the front and rear ends of the first ruler 1, the damping pad 9 prevents the marking plate from rubbing against the upper end of the first ruler 1, and the lever facilitates the movement of the adapter marking rod 7.

[0026] Example 2

[0027] See Figure 1 , Figure 5 Furthermore, based on Embodiment 1, a sealing cap 12 is fixedly provided on one side of the second ruler 4, and a screw 13 is fixedly provided on one side of the front end of the sealing cap 12. The output end of the screw 13 passes through the protrusion on one side of the front end of the first ruler 1 and a nut 14 is threaded on its outer wall.

[0028] Specifically, the sealing cap 12 protects one side of the second ruler 4, and the screw 13 passes through the protrusion and engages with the nut 14 to achieve a fixed connection between the sealing cap 12 and the first ruler 1.

[0029] In actual operation, when it is necessary to measure the length of a shorter object, it is not necessary to remove the sealing cover 12. The adapter mark rod 7 is pushed to slide between the second limit groove 5 and the slide groove 8 to achieve the measurement of the object.

[0030] When the length of the first ruler 1 is insufficient, remove the nut 14, pull the second ruler 4 to make the second ruler 4 grow, continue to push the adapter marking rod 7 through one end of the slide groove 8, and continue to slide inside the second limiting groove 5 inside the second toothed plate 4 to realize the marking of length measurement.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
