Technical Field

[0001] This utility model relates to the field of support device technology, and in particular to a combined engineering surveying level support device. Background Technology

[0002] A level is an instrument used to establish a horizontal line of sight and determine the height difference between two points on the ground at different locations. The principle is to measure the height difference between ground points based on the principle of leveling. With the help of a level, the telescope obtains a horizontal line of sight. By observing the values ​​of the scale rod at different positions facing the telescope through the telescope, the scale rod reading when the line of sight is horizontal can be quickly obtained. The support device of a level usually refers to a tripod.

[0003] Since most of the legs in a tripod are foldable and each leg is independent, when an individual leg is subjected to external pressure during use, the individual leg is prone to folding, thereby reducing the stability of the device in supporting the level.

[0004] Therefore, it is necessary to provide a new combined engineering surveying level support device to solve the above-mentioned technical problems. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0018] Please see Figures 1 to 5 The present invention provides a combined engineering surveying level support device, which includes: a mounting plate 1, and a support component 2 movably mounted below the mounting plate 1.

[0019] In the embodiments of this utility model, please refer to Figures 1 to 5 The support assembly 2 includes a support foot 21, which has multiple support feet and is rotatably connected to the bottom of the mounting plate 1. The outer side of the support foot 21 has an outer mounting groove 212, and the inner side of the support foot 21 has multiple inner mounting grooves 213. A conical block 214 is fixedly connected to the bottom of the support foot 21. A mating protrusion 215 is fixedly connected to both sides of the top of the conical block 214. A connecting plate 22 is embedded in the inner mounting groove 213 through a magnetic block and is attracted to it. Both ends of the connecting plate 22 have mating holes 221. The connecting plate 22 is sleeved on the outside of the mating protrusion 215 through the mating holes 221 and fixed with a nut.

[0020] It should be noted that: by setting the connecting plate 22 in the support assembly 2, when the support leg 21 is unfolded during use, the relatively long connecting plate 22 can be taken out and fitted onto the outer wall of the docking protrusion 215 through the docking hole 221 at its end. Then, by tightening the nut to fix it, multiple independent support legs 21 can be formed into a whole, thereby reducing the impact of the folding of a single independent support leg 21 on the stability of the device during use, thus helping to improve the stability of the device during use.

[0021] In the embodiments of this utility model, please refer to Figures 1 to 5The outer mounting groove 212 is provided with an expansion component 3, which includes a support block 31. The support block 31 is rotatably connected to the outer mounting groove 212. A shock absorber 32 is fixedly connected to the end of the support block 31 away from the outer mounting groove 212. A support frame 33 is fixedly connected to the end of the shock absorber 32 away from the support block 31. Both sides of the support frame 33 are provided with rotatably connected expansion rods 34. A rotating shaft 211 is mounted on the upper part of the outer mounting groove 212. The rotating shaft 211 is fixedly connected to the end of the support block 31. A limiting hole a311 is opened in the outer mounting groove 212 at the corresponding part of the end of the support block 31. A limiting hole b331 is opened in the support frame 33 at the corresponding part of the end of the expansion rod 34. Limiting pins for fixing the support block 31 and the support frame 33 are respectively inserted into the limiting holes a311 and b331.

[0022] It should be noted that: through the opening of the limiting holes a311 and b331, when the support block 31 and support frame 33 are rotated to the required angle during use, the limiting pins are inserted into the corresponding limiting holes a311 and b331 to limit the angle of the support block 31 and support frame 33, thereby allowing the expansion component 3 to unfold smoothly. When the expansion component 3 is unfolded, when the device is tilted due to external force, the protruding expansion rod 34 in the expansion component 3 will first come into contact with the ground. During this process, the shock absorber 32 can also buffer the impact force of the device hitting the ground when it tilts, thereby reducing the probability of the level instrument on the device being damaged due to the impact with the ground when the device tilts.

[0023] In the embodiments of this utility model, please refer to Figures 1 to 5 Multiple evenly distributed top plates 11 are fixedly installed on the bottom of the mounting plate 1. A fixedly connected mounting bracket 13 is installed on the bottom of the top plate 11, and the mounting bracket 13 is rotatably connected to the top of the support foot 21. Both sides of the mounting bracket 13 at the bottom of the top plate 11 are fixedly connected to the stop blocks 12, and the ends of the stop blocks 12 are attracted to the outer wall of the support foot 21 by magnetic blocks.

[0024] It should be noted that: by setting the stop 12, the stop 12 can block the movement trajectory of the support leg 21 when it is in use, so that the support leg 21 can be smoothly adjusted to the required angle when in use, so that the staff can install the connecting piece between adjacent support legs 21 later.

[0025] The working principle of the combined engineering surveying level support device provided by this utility model is as follows: When using this device, the staff can first connect the level instrument used for engineering surveying to the mounting plate 1. After completing the connection between the device and the level instrument, when the level instrument needs to be used, after the staff moves the device to the required position, the relatively short connecting plate 22 installed between the adjacent support legs 21 when folded can be taken out to release the restriction on the multiple support legs 21. Then the taken-out connecting plate 22 can be placed in the corresponding inner mounting slot 213. Next, multiple support feet 21 can be unfolded in sequence, and then the relatively long connecting plate 22 can be taken out from the corresponding inner mounting groove 213 and fitted onto the outer wall of the mating protrusion 215 in two adjacent support feet 21 through the mating hole 221. Then, it can be fixed by tightening the nut, so that multiple unfolded support feet 21 can be connected into a whole, thereby improving the support stability of the support feet 21 for this device and the level instrument. Furthermore, after the support leg 21 is unfolded, the limiting rods in the limiting holes a311 and b331 can be removed to release the limiting on the support block 31 and the outward expansion rod 34, allowing the operator to move them to control the angle of the support block 31 and the outward expansion rod 34. After both are rotated to the desired position, the limiting rods can be reinserted to limit the adjusted support block 31 and the outward expansion rod 34, thereby increasing the outward expansion angle when the device is in use. During subsequent use, when the device is tilted due to external force, the protruding expansion rod 34 will be the first to come into contact with the ground. In this process, the shock absorber 32 can also buffer the impact force of the device coming into contact with the ground when it tilts, thereby reducing the probability of the level instrument on the device being damaged due to the impact of the device hitting the ground when it tilts. Therefore, the safety protection effect of this device can be improved.

[0026] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0027] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
