Description

Technical Field

[0001] This utility model relates to the field of engineering measurement technology, specifically a leveling rod device. Background Technology

[0002] In engineering surveying, the leveling rod (also called a steel ruler or measuring rod) is a common surveying tool, mainly used for precise distance measurement and positioning. It is usually made of steel and has high accuracy and durability. However, leveling with existing leveling rods requires manual experience or other tools, and surveyors need to use additional equipment such as a level to ensure the leveling rod is horizontal or vertical. This process requires the installation and fixing of auxiliary tools, which is relatively slow and can easily affect the overall efficiency of the work. Utility Model Content

[0003] The purpose of this invention is to provide a tower gauge device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tower gauge device, comprising:

[0005] Ta Chi Yi is a cavity with an opening at the top;

[0006] Tower ruler two is placed inside tower ruler one. Tower ruler three is slidably arranged inside tower ruler two. A support rod for measuring the limit height is provided on the top of tower ruler three.

[0007] A limiting sleeve is placed at the ends of the first and second gauges. A balancing bubble is fixed to the outside of the limiting sleeve at the end of the first gauge. A limiting part is installed on the outside of the limiting sleeve to compress and fix the corresponding gauge.

[0008] Preferably, the top of the three-piece tower is fixedly connected to a support base, the support base has an L-shaped structure, and the support rod is rotatably connected to the end of the support base.

[0009] Preferably, a limiting pad is fixedly connected to the middle of the support base, and when the support rod cooperates with the limiting pad, the support rod is perpendicular to the tower gauge.

[0010] Preferably, the limiting part includes a sliding plate slidably connected to the outside of the limiting sleeve. The sliding plate has a U-shaped structure. A limiting hole is opened on one side of the limiting sleeve. An extrusion rod is slidably connected inside the limiting hole. The extrusion rod is slidably connected to the inner wall of the sliding plate.

[0011] Preferably, the end of the limiting sleeve opposite to the extrusion rod is fixedly connected to a limiting groove, the end of the sliding plate is slidably connected to the limiting groove, and a groove for driving the sliding plate is formed in the middle of the limiting groove.

[0013] Preferably, both one side of the second tower ruler and one side of the third tower ruler are provided with limiting grooves that cooperate with the extrusion rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In the stored state, the compression rod of the limiting part compresses and fixes the two and three measuring rods, effectively preventing them from loosening and elongating due to shaking during carrying, ensuring the stability and reliability of the measuring rods, and avoiding damage or inconvenience that may be caused by accidental elongation of the measuring rods. After the measuring rods are elongated, under the action of the spring force, the sliding plate drives the compression rod to pass through the limiting hole and insert into the corresponding limiting groove, thereby achieving the limiting and fixing of the elongation length of the measuring rods; a balance bubble is fixedly connected to the outer side of the limiting sleeve at one end of the measuring rod. When in use, by placing the measuring rod one in contact with the ground and observing the balance bubble, the horizontal status of the measuring rod can be accurately judged; the operator can adjust the measuring rod according to the indication of the balance bubble to make it in a horizontal position, thereby ensuring the accuracy and reliability of the measurement results and reducing the measurement error caused by the tilt of the measuring rod.

[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] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a height gauge device, comprising: a height gauge 1, which is a cavity with an opening at the top; a height gauge 2 slidably installed inside the height gauge 1, a height gauge 3 slidably disposed inside the height gauge 2, and a support rod 5 for measuring the height limit provided at the top of the height gauge 3; a limiting sleeve 8 placed at the ends of the height gauge 1 and the height gauge 2, a balancing bubble 9 fixedly connected to the outside of the limiting sleeve 8 at the end of the height gauge 1, and a limiting part installed on the outside of the limiting sleeve 8 for squeezing and fixing the corresponding height gauge.

[0023] It should be noted that, in this embodiment, when in use, the ruler 1 is placed in contact with the ground, and the level of the ruler body is observed through the balance bubble 9. If necessary, the rulers 2 and 3 can be pulled outwards and then fixed in place by the limiting part. When the rulers 2 and 3 are in the stored state, the compression rod 11 of the limiting part compresses and fixes the rulers 2 and 3 to prevent them from loosening and elongating during carrying.

[0024] In one embodiment, a support base 4 is fixedly connected to the top of the three-piece treadmill 3. The support base 4 has an L-shaped structure. A support rod 5 is rotatably connected to the end of the support base 4. A limiting pad 6 is fixedly connected to the middle of the support base 4. When the support rod 5 cooperates with the limiting pad 6, the support rod 5 is perpendicular to the three-piece treadmill 3.

[0025] It should be noted that in this embodiment, the rotational connection between the support rod 5 and the support base 4 is an interference fit. During transport, the support rod 5 is rotated to a vertically downward position so that it fits against the outer side of the leveling rod 1, thus preventing it from being carried. When it is necessary to measure the height, the support rod 5 is rotated and placed on top of the limiting pad 6. At this time, the support rod 5 is perpendicular to the leveling rod 3. The bottom of the leveling rod 1 is brought into contact with the ground. The leveling rod 1 is adjusted to a horizontal position using the balancing bubble 9. The leveling rod 3 is then adjusted so that the support rod 5 contacts the top measurement position, thereby measuring the top height.

[0026] In one embodiment, the limiting part includes a sliding plate 10 slidably connected to the outside of the limiting sleeve 8. The sliding plate 10 has a U-shaped structure. A limiting hole 14 is opened on one side of the limiting sleeve 8. A pressing rod 11 is slidably connected inside the limiting hole 14. The pressing rod 11 is slidably connected to the inner wall of the sliding plate 10. A limiting groove 12 is fixedly connected to one end of the limiting sleeve 8 away from the pressing rod 11. The end of the sliding plate 10 is slidably connected to the limiting groove 12. A groove for driving the sliding plate 10 is opened in the middle of the limiting groove 12. A spring 13 is fixedly connected to one end of the inner wall of the sliding plate 10. A round tube is fixedly connected to the inside of the sliding plate 10 and inside the spring 13. A sliding rod is slidably connected inside the round tube. The sliding rod is fixedly connected to the limiting sleeve 8. The spring 13 is fixedly connected to the end of the limiting sleeve 8. A limiting groove 7 that cooperates with the pressing rod 11 is opened on one side of the second measuring rod 2 and one side of the third measuring rod 3.

[0027] It should be noted that, in this embodiment, when it is necessary to pull out the two-piece scale 2 and the three-piece scale 3, the hand presses the sliding plate 10 through the groove in the middle of the limiting slide groove 12. The sliding plate 10, under the compression of the spring 13, drives the compression rod 11 to separate from the limiting groove 7 corresponding to the two-piece scale 2 or the three-piece scale 3, so that the two-piece scale 2 or the three-piece scale 3 can be pulled out. When the hand separates from the sliding plate 10, under the elastic force of the spring 13, the sliding plate 10 drives the sliding plate 10 to pass through the limiting hole 14 and insert into the corresponding limiting groove 7. The end of the limiting groove 7 is fixed with a rubber pad, so as to limit the two-piece scale 2 or the three-piece scale 3 through friction and prevent it from loosening when not in use.
