Technical Field
[0001] The utility model relates to the technical field of measuring poles; more specifically, it relates to a on-site measuring pole. Background Art
[0002] A pole is a measuring tool made of wooden or iron poles, painted with red and white paint or scales. The bottom of the pole is generally conical, which is convenient for staff to set it up on the ground for measurement. It is mainly used to indicate the measurement point, generally used in construction engineering survey operations, to facilitate the construction personnel to work quickly, so as to achieve the purpose of effective measurement positioning, ensuring the operation quality and work efficiency.
[0003] At present, in the process of using the measuring pole in the prior art, although the cone at the bottom is convenient for inserting the pole into the ground, when manually carrying or transporting the pole, the cone at the bottom of the pole is exposed and easily harms the users, which reduces the safety of the equipment to a certain extent. And in order to ensure the measurement accuracy, the pole needs to be kept vertical, but currently there is a lack of a calibration device for the verticality of the pole during use, which reduces the practicability of the equipment to a certain extent. Therefore, there is an urgent need for a on-site measuring pole to solve the above problems. Summary of the Utility Model

Rectangular limiting plates are provided on the inner wall surfaces of both sides of the connecting cylinder, and the rectangular limiting grooves are clamped and slidably connected to the outer surfaces of the rectangular limiting plates. When the inserting rod moves, it can drive the fixed disk to move synchronously, and the rectangular limiting grooves move synchronously on the outer surfaces of the rectangular limiting plates, thereby preventing the fixed disk from deflecting.
[0012] Preferably, the supporting structure further includes a moving groove, and the moving groove is formed inside both sides at the middle position of the connecting disk. A positioning rod and a spring are arranged inside the moving groove. A bubble level is installed inside the upper end surface of the connecting disk, and a fixed rod is fixedly connected to the bottom surface of the connecting disk, and there are three groups of fixed rods. A tightening bolt is threadedly connected to the inside of the outer surface of one side of the lower end of the fixed rod, and a telescopic rod is inserted into the fixed rod, and the lower end of the telescopic rod is universally hinged to a supporting base. This design can pull out the telescopic rod outward inside the fixed rod.

Positioning holes are formed inside the outer surfaces on both sides of the upper end of the connecting cylinder, and the internal dimensions of the positioning holes are adapted to the external dimensions of the other end of the positioning rod. This design can support the positioning rod through the elasticity of the spring itself, so that the outer surface of the other end of the positioning rod is inserted into the positioning holes, thereby fixing the position of the connecting disk.
[0014] The technical effects and advantages of the present utility model: By rotating the turntable of the present utility model, the threaded rod rotates synchronously. At this time, the inserting rod moves upward on the outer surface of the threaded rod, so that the inserting rod can be received inside the connecting cylinder, thereby preventing the inserting rod from being exposed and hurting the user, and improving the safety of the equipment during use to a certain extent;
[0015] By pulling out the telescopic rod outward inside the fixed rod, the bottom surface of the support base is stably supported on the ground, and the bubble level is used to observe whether the device is in a horizontal state.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the drawings in the present utility model. In addition, the forms of the various structures described in the following embodiments are merely examples, and the measuring rod related to the present utility model is not limited to the various structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.
[0023] Embodiment 1
[0024] As Figures 1 - 3 shown, this embodiment provides a on-site measuring rod, including a connecting cylinder 1. A storage structure 2 is arranged inside the connecting cylinder 1, and a connecting rod 3 is arranged at the upper end of the storage structure 2. A support structure 4 is arranged on the outer surface of the upper end of the connecting cylinder 1;
[0025] Storage structure 2, the storage structure 2 includes a connecting sleeve 22, and a connecting rod 3 is threadedly connected inside the connecting sleeve 22. A connecting screw rod is fixedly connected to the outer surface of the lower end of the connecting rod 3, and a connecting screw groove is opened inside the outer surface of the upper end of the connecting rod 3. Moreover, the outer dimensions of the connecting screw rod are adapted to the inner dimensions of the connecting screw groove, and the outer dimensions of the connecting screw rod are adapted to the inner dimensions of the connecting sleeve 22. Thus, multiple groups of connecting rods 3 can be threadedly connected end to end, and the connecting rod 3 can be threadedly connected to the connecting sleeve 22. Thereby, it is convenient to adjust the height dimension when the equipment is in use according to the actual situation, and it is convenient to disassemble, store and carry the equipment;
[0026] The storage structure 2 further includes a turntable 21, and the turntable 21 is snap-connected to the inside of the upper end surface of the connecting cylinder 1, and the connecting sleeve 22 is fixedly connected to the upper end surface of the turntable 21. A snap ring is arranged on the outer surface of the lower end of the turntable 21, and a snap groove is opened inside the upper end surface of the connecting cylinder 1, and the snap ring is snap-connected to the inside of the snap groove. When the turntable 21 rotates, the snap ring rotates synchronously inside the snap groove, making the turntable 21 more stable when rotating, and avoiding the situation that the turntable 21 is disengaged from the inside of the upper end surface of the connecting cylinder 1;
[0027] A threaded rod 23 is fixedly connected to the bottom surface of the turntable 21, and a plug rod 24 is threadedly connected to the outer surface of the threaded rod 23, and a fixed disk 25 is fixedly connected to the outer surface of the plug rod 24. When the turntable 21 rotates clockwise, the threaded rod 23 rotates clockwise synchronously. At this time, the plug rod 24 moves downward on the outer surface of the threaded rod 23, so that the plug rod 24 extends out of the inside of the connecting cylinder 1 and is inserted into the soil, thereby stably supporting the equipment. When the turntable 21 rotates counterclockwise, the threaded rod 23 rotates counterclockwise synchronously. At this time, the plug rod 24 moves upward on the outer surface of the threaded rod 23, so that the plug rod 24 contracts into the inside of the connecting cylinder 1, thereby avoiding the situation that the plug rod 24 is exposed outside and causing injury to the staff;
[0028] Rectangular limiting grooves are opened inside the outer surfaces on both sides of the fixed disk 25, rectangular limiting plates are arranged on the inner wall surfaces of both sides inside the connecting cylinder 1, and the rectangular limiting grooves are snap-slidingly connected to the outer surfaces of the rectangular limiting plates. When the plug rod 24 moves upward or downward, the fixed disk 25 moves synchronously with the plug rod 24, and the rectangular limiting grooves slide on the outer surfaces of the rectangular limiting plates synchronously, thereby avoiding the situation that the plug rod 24 rotates inside the connecting cylinder 1, making the plug rod 24 move more stably. At the same time, the design of the fixed disk 25 can avoid the situation that the plug rod 24 is disengaged from the inside of the connecting cylinder 1.
[0029] Embodiment 2
[0030] As Figures 4 - 5As shown, based on the same concept as the above embodiment, this embodiment also proposes:
[0031] A support structure 4, the support structure 4 includes a connection plate 41, and the connection plate 41 is sleeved on the outer surface of the upper end of the connection cylinder 1. Positioning holes are opened inside the outer surfaces on both sides of the upper end of the connection cylinder 1, and the internal dimensions of the positioning holes are adapted to the external dimensions of the other end of the positioning rod 43. The support structure 4 also includes a moving groove 42, and the moving groove 42 is opened inside both sides at the middle position of the connection plate 41, and a positioning rod 43 and a spring 44 are arranged inside the moving groove 42. The positioning rod 43 is inserted into the moving groove 42, and both ends of the spring 44 respectively abut against the outer surface of one end of the positioning rod 43 and one side surface inside the moving groove 42. When the outer surface of the other end of the positioning rod 43 is inserted into the positioning hole, the connection between the connection plate 41 and the outer surface of the upper end of the connection cylinder 1 is completed. When the outer surface of the other end of the positioning rod 43 disengages from the inside of the positioning hole, the connection plate 41 and the outer surface of the upper end of the connection cylinder 1 are separated. This design can support the positioning rod 43 through the self-elasticity of the spring 44, so that the positioning rod 43 can be stably inserted into the positioning hole.
[0032] A pull plate is arranged on the outer surface of one end of the positioning rod 43, and the pull plate penetrates and extends out of the inside of the moving groove 42. It is convenient to pull the positioning rod 43 to move through the pull plate, and after the positioning rod 43 is pulled, the positioning rod 43 can be self-reset through the self-elasticity of the spring 44, thus facilitating the installation and disassembly between the connection plate 41 and the connection cylinder 1.
[0033] A bubble level 45 is installed inside the upper surface of the connection plate 41, and a fixed rod 46 is fixedly connected to the bottom surface of the connection plate 41, and there are three groups of fixed rods 46. A tightening bolt 47 is threadedly connected to the inside of the outer surface of one side of the lower end of the fixed rod 46, and a telescopic rod 48 is inserted into the fixed rod 46, and the lower end of the telescopic rod 48 is universally hinged to a support base 49. The bubble level 45 can be used to observe whether the device is in a horizontal state. When there are pits or slopes on the ground, the three telescopic rods 48 are respectively pulled outwards inside the three fixed rods 46, and then the support base 49 is hinged and rotated so that the bottom surface of the support base 49 supports on the ground. When the device is adjusted to a horizontal state, the tightening bolt 47 is rotated to fix the position of the telescopic rod 48, thereby maintaining the horizontal state of the device and making the measurement more accurate.
[0034] Working principle: When the device is in use, pull the positioning rod 43 inside the moving slot 42, and then sleeved the connecting disc 41 on the outer surface of the upper end of the connecting cylinder 1. Due to the elastic force of the spring 44, the outer surface of the other end of the positioning rod 43 is inserted into the positioning hole opened on the upper surface of the connecting cylinder 1, thus completing the connection between the connecting cylinder 1 and the support structure 4. Then, pull out the telescopic rod 48 outward from the inside of the fixed rod 46 in sequence, and hinge and rotate the support base 49 so that its bottom surface fits the ground. At this time, observe the bubble level 45 to determine whether the device is in a horizontal state. If it is not in a horizontal state, then adjust the positions of the telescopic rod 48 and the support base 49. If it is in a horizontal state, then rotate the tightening bolt 47 to fix the position of the telescopic rod 48;
[0035] When the device is in use, rotate the turntable 21 so that the threaded rod 23 rotates synchronously. At this time, the insertion rod 24 moves downward on the outer surface of the threaded rod 23, and synchronously drives the fixed disc 25 to move downward inside the connecting cylinder 1. Thus, the insertion rod 24 extends out of the inside of the connecting cylinder 1 and is inserted into the soil, thereby stably supporting the device through the storage structure 2. Subsequently, take an appropriate number of connecting rods 3 according to the needs. Hold the turntable 21 by hand and thread-connect a group of connecting rods 3 with the connecting sleeve 22. Then, hold the turntable 21 by hand and thread-connect the remaining groups of connecting rods 3 end to end in sequence, thus completing the assembly of the device, facilitating the use of the device. When the device is used up, perform the above operations in reverse to disassemble the device, facilitating the storage and carrying of the device. The above is the entire working principle of this utility model.
