Description

Technical Field

[0001] This utility model relates to the field of engineering testing, and in particular to a benchmark for engineering testing. Background Technology

[0002] A benchmark is a tool used to obtain graphic and location information reflecting the current state of the ground by measuring existing feature points and boundaries. This information is used for planning, design, and administration of engineering projects. Engineering surveying uses instruments such as levels, measuring instruments, and benchmarks. Among these, the benchmark is a device used for measurement and positioning. During surveying, measuring rods are often carried to locate buildings, align points, and measure distances.

[0003] Engineering testing markers are often of fixed length, and to ensure wide applicability, they are generally quite long. After use, these markers need to be carried and moved manually. However, due to their length, they occupy a lot of space and are difficult to carry. Moving these markers is inconvenient and laborious, making them unsuitable for workers to carry on construction sites. Therefore, a new type of engineering testing marker is proposed to solve these problems. Utility Model Content

[0029] 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.

[0030] Reference Figure 1 , Figure 2 The present invention provides an embodiment of an engineering inspection marker, comprising an upper rod 1 and a lower rod 2. A connecting block 3 is hinged to the bottom of the upper rod 1, and the bottom of the connecting block 3 is hinged to the top of the lower rod 2. The connecting block 3 connects the upper rod 1 and the lower rod 2 by means of hinge, so that the upper rod 1 and the lower rod 2 can be folded together, reducing the space occupied by the marker when stored and carried, and making it easier to carry. A fixing mechanism 18 is provided on the surface of the lower rod 2.

[0031] Reference Figure 1 - Figure 3 A sleeve 11 is fitted onto the surface of the lower rod 2. The inside of the sleeve 11 and the outer wall of the lower rod 2 are always in contact. When the sleeve 11 moves upward, it will simultaneously fit onto the surfaces of the upper rod 1 and the lower rod 2, preventing the upper rod 1 and the lower rod 2 from freely changing their angles, thus facilitating measurement. A control mechanism 19 is provided inside the lower rod 2. The control mechanism 19 includes a limiting cylinder 12 and a slider 13. The outer wall of the limiting cylinder 12 is in contact with the inner wall of the sleeve 11. The limiting cylinder 12 is fixedly connected to the circumferential surface of the slider 13, and the slider 13 is in contact with the inner wall of the lower rod 2.

[0032] Reference Figure 2 , Figure 3 A second spring 14 is fixedly connected to the bottom of the slider 13. The bottom of the second spring 14 is fixedly connected to the inner wall of the lower rod 2. The second spring 14 applies a downward elastic force to the slider 13. The surface of the lower rod 2 is provided with a groove 15 that can accommodate the limiting cylinder 12. The groove 15 is L-shaped. The inner wall of the groove 15 contacts the outer wall of the limiting cylinder 12. A support mechanism 20 is provided at the bottom of the lower rod 2.

[0033] Reference Figure 1 , Figure 2 , Figure 4 The fixing mechanism 18 includes a fixing block 4, which is fixedly connected to the outer wall of the lower rod 2. The rear side of the fixing block 4 is provided with an installation groove 5 for accommodating the upper rod 1. When the upper rod 1 is rotated and placed in the installation groove 5, the upper rod 1 and the lower rod 2 can be folded and stored.

[0034] Reference Figure 4 The fixing mechanism 18 also includes a pull ring 6, which allows the user to easily pull the control rod 7 to move, saving effort. The right side of the pull ring 6 is fixedly connected to the control rod 7, which is slidably connected to the inner wall of the fixing block 4. The sliding direction of the control rod 7 is left and right. The left side of the upper rod body 1 is provided with a control groove 10 that cooperates with the control rod 7. The fixing mechanism 18 also includes a control ring 8, which is fixedly connected to the outer wall of the control rod 7. The left side of the control ring 8 is elastically connected to the inner wall of the fixing block 4 through a spring 9. The spring 9 applies a rightward elastic force to the control ring 8 and the control rod 7.

[0035] Reference Figure 1 - Figure 3 The support mechanism 20 includes a support base 16, which is fixedly connected to the bottom of the lower rod body 2. The support mechanism 20 also includes a cone 17, which is fixedly connected to the bottom of the support base 16. The cone 17 is inserted into the ground and its sharp shape can be used to fix it firmly to the ground, providing stable support for the pole and improving the stability of the pole during operation, thereby improving the accuracy of measurement.

[0036] Working principle: When in use, insert the cone 17 into the ground. Its sharp shape can be firmly fixed on the ground, providing stable support for the marker. Then, pull the pull ring 6 to the left, which will drive the control rod 7 and control ring 8 to move to the left against the elastic force of the spring 9. This will cause the control rod 7 to disengage from the control groove 10 on the left side of the upper rod body 1. Then, rotate the upper rod body 1 around the hinge point between the connecting block 3 and the lower rod body 2 to unfold it, so that the upper rod body 1 and the lower rod body 2 remain vertical and on the same straight line.

[0037] Then, push the limiting cylinder 12 upward, causing the slider 13 to overcome the elastic force of the second spring 14 and move upward inside the L-shaped groove 15, stretching the second spring 14. The sleeve 11 moves upward with the limiting cylinder 12. When the limiting cylinder 12 moves to the top of the groove 15, the path of the groove 15 begins to rotate downward. At this time, release the limiting cylinder 12. Driven by the second spring 14, the sleeve 11, the limiting cylinder 12, and the slider 13 all begin to move downward and are stuck in the short side of the L-shape of the groove 15. This allows the sleeve 11 to be simultaneously fitted onto the surfaces of the upper rod 1 and the lower rod 2, completing the fixation of the unfolded upper rod 1 and lower rod 2, making the upper rod 1 and lower rod 2 a longer whole, which facilitates the measurement work.

[0038] After the measurement work is completed, when it is necessary to fold and store the upper rod 1 and the lower rod 2, push the limiting cylinder 12 upward. When the limiting cylinder 12 moves to the top of the groove 15, release the limiting cylinder 12. Under the action of the spring 14, the sleeve 11, the limiting cylinder 12 and the slider 13 all begin to move downward, so that the sleeve 11 completely disengages from the surface of the lower rod 2. At this time, the angle between the upper rod 1 and the lower rod 2 can be freely rotated. Then, rotate the upper rod 1 into the mounting groove 5 of the fixing block 4, and then insert the control rod 7 into the control groove 10 to fix the upper rod 1 and the lower rod 2 after folding, making it convenient for staff to carry.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
