Description

Technical Field

[0001] The utility model relates to the field of land surveying and mapping, and specifically relates to a level for land spatial planning surveying and mapping. Background Technique

[0002] In the field of land spatial planning surveying and mapping, as a core instrument for obtaining terrain elevation data, the stability and portability of the level directly affect the surveying accuracy and operation efficiency.

[0003] Most traditional level tripods adopt a fixed foot nail structure. Although this structure can provide certain support during measurement, when it is necessary to transfer the measurement point, it is necessary to manually lift the heavy tripod for movement, which not only consumes manpower, but also easily causes damage to the precision components inside the level due to collision or uneven ground. Although some improved tripods are provided with moving wheels, the moving wheels are not convenient for flexible retraction and extension, which affects the accuracy and convenience of the measurement work. Content of the Utility Model

[0004] The purpose of the utility model is to provide a level for land spatial planning surveying and mapping, so as to solve the problem that the conventional level support is inconvenient to move proposed in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A level for land spatial planning surveying and mapping, including a spirit level and a support composed of a base, a telescopic rod, and a foot nail assembly. The bottom of the telescopic rod is rotatably installed with an installation frame. The top of the installation frame is connected to the telescopic rod through an elastic member. A positioning frame for accommodating the foot nail is provided at the central position of the installation frame. A shock-absorbing wheel is fixedly installed at the bottom of the installation frame.

[0006] Preferably, a pair of guide rods are rotatably installed on the side wall of the telescopic rod. The two sides of the installation frame are respectively slidably connected to the guide rods through positioning pins. A sliding hole for the positioning pin to slide is provided on the side wall of the guide rod.

[0007] Preferably, the elastic member is a tension spring. A pair of fixed rods are fixedly installed on one side of the telescopic rod. A protrusion is integrally formed at the top of the installation frame, and a hanging nail is fixedly installed at the position of the protrusion. The two ends of the tension spring are respectively connected to the fixed rod and the hanging nail.

[0008] Preferably, an installation ear is integrally formed on the side wall of the telescopic rod, and the fixed rod is fixedly installed in the installation ear.

[0009] Preferably, the positioning frame is composed of several support rods and anti-detachment caps. The anti-detachment cap is provided with a circular hole for accommodating the foot nail.

[0010] Preferably, the corners of the guide rod and the installation frame are all smoothly transitioned with rounded corners.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] With the shock-absorbing wheels, guide rods, mounting brackets and tension springs provided at the bottom of the telescopic rod of the present utility model, the mounting brackets cooperate with the tension springs to enable the flexible retraction and extension of the shock-absorbing wheels. When measurement work needs to be carried out, the shock-absorbing wheels can be retracted, allowing the foot nails of the telescopic rod to firmly contact the ground, ensuring that the level is in a stable measurement state; while when the level needs to be moved, the mounting brackets are rotated to let the shock-absorbing wheels fall, and easy displacement can be achieved by means of the rolling of the shock-absorbing wheels. The structure is simple, the operation is convenient, and the convenience of land surveying and mapping operations is effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 5The utility model provides a technical solution: a level for land space planning and surveying, including a level 1 and a bracket composed of a base 2, a telescopic rod 3, and a foot nail 7. The connection structure between the level 1 and the base 2 is the existing technology. The bottom of the telescopic rod 3 is rotatably installed with a mounting frame 6, and the side wall of the telescopic rod 3 is rotatably installed with a pair of guide rods 5. The two sides of the mounting frame 6 are respectively slidably connected to the guide rods 5 through positioning pins. The corner connections between the guide rods 5 and the mounting frame 6 are chamfered and smoothly transitioned. The advantage of this arrangement is that sharp corners can avoid scratching the skin. The side wall of the guide rod 5 is provided with a sliding hole 13 for the positioning pin to slide, and the top of the mounting frame 6 is connected to the telescopic rod 3 through an elastic member. The elastic component is a tension spring 9, and the setting of the tension spring 9 is conducive to limiting the different positions of the mounting frame 6. A pair of fixing rods 10 are fixedly installed on one side of the telescopic rod 3, and the side wall of the telescopic rod 3 is integrally formed with a mounting ear, and the fixing rod 10 is fixedly installed in the mounting ear. The top of the mounting frame 6 is integrally formed with a protrusion 8, and a hanging nail 12 is fixedly installed at the position of the protrusion 8. The two ends of the tension spring 9 are respectively connected to the fixing rod 10 and the hanging nail 12.

[0022] See also Figure 6 A positioning frame 11 for accommodating the foot spike 7 is provided at the central position of the mounting frame 6. The positioning frame 11 is composed of a plurality of support rods and an anti-dropping cap. The anti-dropping cap is provided with a circular hole for accommodating the foot spike 7. A shock-absorbing wheel 4 is fixedly installed at the bottom of the mounting frame 6. The shock-absorbing wheel 4 can effectively absorb and buffer the vibration from the ground, reduce the vibration transmitted to the level, reduce the impact force on the level, and extend the service life of the instrument.

[0023] When it is necessary to use the shock-absorbing wheel 4 to support the telescopic rod 3, the guide rod 5 is driven to rotate around the axis by rotating the mounting frame 6 until the mounting frame 6 is located below the telescopic rod 3, and the angle of the guide rod 5 is adjusted until the foot nail 7 is inserted into the positioning frame 11. The positioning pin provided on the mounting frame 6 slides to the top of the sliding hole 13 under the action of the tension spring 9, ensuring that the positioning frame 11 is stably inserted at the bottom of the telescopic rod 3. The mounting frame 6 provides support for the telescopic rod 3. Installing the shock-absorbing wheel 4 at the bottom of the telescopic rod 3 can make the bracket more stable during movement, reduce damage to the instrument caused by collision or ground bumps, and also facilitate operation and improve work efficiency.

[0024] By arranging the shock-absorbing wheel 4, the guide rod 5, the mounting frame 6 and the tension spring 9 at the bottom of the telescopic rod 3, the mounting frame 6 cooperates with the tension spring 9 to realize the flexible retraction and extension of the shock-absorbing wheel 4. When measuring work is required, the shock-absorbing wheel 4 can be retracted to allow the foot nails 7 of the telescopic rod 3 to firmly contact the ground, ensuring that the level is in a stable measuring state; when the level needs to be moved, the mounting frame 6 is rotated to make the shock-absorbing wheel 4 fall, and easy displacement is achieved with the help of the rolling of the shock-absorbing wheel 4. The structure is simple and the operation is convenient, which effectively improves the convenience of land surveying and mapping operations.
