Description

Technical Field

[0001] The utility model relates to a bracket, in particular to a portable geodetic observation bracket. Background Art

[0002] Geodes are mainly used to accurately measure various geographic parameters on the earth's surface, including location coordinates (longitude, latitude), elevation, angle and distance, etc. These instruments are widely used in different fields and environments.

[0003] Since geodetic instruments are often used for surveying in different environments and fields, an observation bracket that provides stable support for the geodetic instrument is particularly important. Also, since the staff need to frequently move the surveying locations and the surveyors need to quickly start the surveying work after arriving at the surveying locations, the existing observation brackets require the staff to repeatedly disassemble and install them, which wastes the staff's time and brings great inconvenience to the users.

[0004] Based on this, it is necessary to design a portable geodetic observation bracket with efficient deployment and convenient storage to meet the requirements of flexibility, convenience and accuracy in field measurement work. Utility Model Content

[0005] The technical solution of the utility model is: a portable geodetic observation bracket, including a placing table, a protrusion, a support plate one, a sliding plate, a support plate two and a limit assembly, the measuring instrument body is rotatably installed on the placing table, and no less than two groups of protrusions are evenly spaced at the bottom of the placing table, each group of protrusions is rotatably connected to a support plate one, a sliding plate is slidably arranged inside the support plate one, the bottom of the sliding plate is rotatably connected to the support plate two, and a limit assembly for fixing the support plate two and the sliding plate is arranged on the sliding plate.

[0006] Furthermore, the limit assembly includes a limit rod, a pin and two springs. The limit rods are arranged in parallel in the sliding plate. The limit rods are provided with holes evenly spaced along the longitudinal direction thereof. The sliding plate is slidably provided with a pin for inserting into the hole, and two springs are arranged between the end of the pin and the sliding plate.

[0007] Furthermore, it also includes a supporting block and a connecting block. The connecting block is rotatably arranged at the bottom of the second supporting plate, and the bottom of the connecting block is rotatably connected to the supporting block.

[0008] Furthermore, it also includes an arc ring, a guide rod and a spring. Both ends of the arc ring are slidably connected to the guide rods. The guide rods slide through the arc ring. A spring is arranged between the end of the guide rod and the arc ring. The two arc rings together form a circular ring for limiting the support plate.

[0009] Furthermore, L-shaped placement blocks are symmetrically arranged at the bottom of the placement table, and the L-shaped placement blocks are used to place the arc ring.

[0010] Furthermore, it also includes a semi-cylindrical box and a handle. The two semi-cylindrical boxes are rotatably connected together through a hinge axis. The two semi-cylindrical boxes are used to provide a placement space for the observation bracket. A handle is provided on one side of the two semi-cylindrical boxes away from the hinge axis.

[0011] Furthermore, the area of ​​the cross section of the upper end of the sliding plate is greater than the area of ​​the cross section of the lower end of the supporting plate.

[0012] Furthermore, the support plate can rotate at an angle less than 180 degrees.

[0013] The beneficial effect is: support plate one is rotated to a state perpendicular to the placement table, the top of the sliding plate slides up to the topmost end of the inner cavity of support plate one, support plate one, the sliding plate and support plate two are in the same straight line, and support plate one is limited by two arc rings, thereby realizing that the observation bracket can be conveniently stored and placed in the semi-cylindrical box. When it needs to be unfolded, by rotating support plate one, adjusting the sliding plate downward and adjusting the height of the sliding plate on support plate two, the observation bracket can be flexibly unfolded according to the needs of use, thereby achieving the effect of conveniently unfolding and efficiently storing the observation bracket, and realizing its easy-to-carry function.

DETAILED DESCRIPTION

[0023] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Embodiment: A portable geodetic observation bracket, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, it includes a placement table 1, a protrusion 102, a support plate 1 2, a sliding plate 21, a support plate 2 3 and a limit assembly. The measuring instrument body 100 is rotatably mounted on the placement table 1. Three groups of protrusions 102 are evenly spaced at the bottom of the placement table 1. Each group of protrusions 102 includes two symmetrically arranged protrusions 102. A support plate 1 2 is rotatably connected to each group of protrusions 102. The support plate 1 2 can rotate at an angle less than 180 degrees with the protrusion 102 as the center. A sliding plate 21 is slidably arranged inside the support plate 1 2. The sliding plate 21 is slidably arranged inside the support plate 1 The area of ​​the cross section of the upper end of 21 is larger than the area of ​​the cross section of the lower end of the support plate 2. This arrangement can prevent the sliding plate 21 from sliding out of the support plate 2, thereby facilitating quick deployment and storage. The lower end of the sliding plate 21 is in a "mouth" shape. The lower end of the sliding plate 21 is rotatably connected to the support plate 2 3. The support plate 2 3 is provided with a longitudinal through groove. The lower end of the sliding plate 21 can move along the longitudinal sliding groove provided on the support plate 2 3. The support plate 3 and the sliding plate 21 are provided with a limiting component for fixing the support plate 2 3 and the sliding plate 21.

[0025] like Figure 6 and Figure 7 As shown, the limit assembly includes a limit rod 31, a latch 211 and a second spring 212. Two limit rods 31 are arranged in parallel in the sliding plate 21. Plug holes 311 are evenly spaced along the longitudinal direction thereof. A latch 211 for inserting into the plug hole 311 is slidably arranged on the sliding plate 21. The end of the latch 211 facing the plug hole 311 is spherical, and the radius of the sphere is adapted to the radius of the plug hole 311. A second spring 212 is arranged between the end of the latch 211 and the sliding plate 21. The two ends of the second spring 212 are respectively connected to the sliding plate 21 and the latch 211. Under the action of the elastic force of the second spring 212, the latch 211 maintains a tendency to be inserted into the plug hole 311. Therefore, when the sliding plate 21 makes relative movement along the limit rod 31, when the latch 211 is facing the plug hole 311, the latch 211 is inserted into the plug hole 311.

[0026] like Figure 1 As shown, it also includes a support block 4 and a connecting block 41. The connecting block 41 is rotatably provided at the bottom of the support plate 23. The bottom of the connecting block 41 is rotatably connected to the support block 4. The bottom of the support block 4 is anti-slip. Through the contact between the support block 4 and the placement plane, a stable supporting force is provided for the observation bracket.

[0027] like Figure 4 As shown, it also includes an arc ring 5, a guide rod 51 and a spring 52. Both ends of the arc ring 5 are slidably connected with the guide rod 51. The guide rod 51 slides through the arc ring 5. A spring 52 is arranged between the end of the guide rod 51 and the arc ring 5. The two arc rings 5 ​​are surrounded to form a circular ring for limiting the support plate 2. When in use, the two arc rings 5 ​​are spread apart, and the two arc rings 5 ​​compress the spring 52. At this time, the two arc rings 5 ​​can be placed on the outside of the support plate 2. After the arc rings 5 ​​are released, under the elastic force of the spring 52, the two arc rings 5 ​​are surrounded to form a circular ring and limit the support plate 2.

[0028] like Figure 3 As shown, L-shaped placement blocks 101 are symmetrically arranged at the bottom of the placement table 1 , and the L-shaped placement blocks 101 are used to place the arc ring 5 .

[0029] like Figure 8 As shown, it also includes a semi-cylindrical box body 6 and a handle 61. The two semi-cylindrical box bodies 6 are rotatably connected together by a hinge axis. The two semi-cylindrical box bodies 6 are enclosed to provide a placement space for the observation bracket. The two semi-cylindrical box bodies 6 are enclosed to provide a storage space for the observation bracket to provide damage protection. At the same time, the two semi-cylindrical box bodies 6 can also provide a limiting effect for the observation bracket after storage to prevent it from unfolding autonomously. A handle 61 is provided on the side of the two semi-cylindrical box bodies 6 away from the hinge axis. The handle 61 is used to lock the two semi-cylindrical box bodies 6 after being enclosed. At the same time, the handle 61 also facilitates the lifting of the storage box formed by the two semi-cylindrical boxes 6, thereby realizing the function of being portable.

[0030] When the bracket needs to be unfolded, the support plate 2 is rotated and unfolded (such as Figure 1 As shown), the observation bracket is then stably placed on the placement plane by contacting the support block 4 with the placement plane; then, the sliding plate 21 is pulled downward, sliding downward along the support plate 1 2, and a suitable angle is formed between the bottom of the sliding plate 21 and the support plate 2 3, and the sliding plate 21 is fixed to the support plate 2 3 by plugging and matching with the plug pin 211 and the plug hole 311, so that the height of the observation bracket can be flexibly adjusted according to needs; when the observation bracket needs to be stored, the support plate 1 2 is rotated to the position as shown in FIG. Figure 3The state shown is shown, and the arc ring 5 is removed from the L-shaped placement block 101 and is sleeved on the support plate 2. The two arc rings 5 ​​are surrounded and the support plate 2 is limited by the elastic force of the spring 52. Then, the sliding plate 21 is moved along the support plate 2 to the top of the inner cavity of the support plate, and the support plate 23 is pulled downward to make the support plate 2, the sliding plate 21 and the support plate 23 in the same straight line. The uppermost socket 311 of the limiting rod 31 is plugged into the pin 211, and the support block 4 is rotated 90 degrees so that the observation bracket is stored as shown. Figure 2 In the state shown, the observation bracket can be placed in the semi-cylindrical box 6, and the two semi-cylindrical boxes 6 are surrounded to store and fix the observation bracket, and the observation bracket can be carried away easily through the handle 61; in this way, the observation bracket can be efficiently stored and carried around; at the same time, when it is needed, it can be easily unfolded to provide stable and flexible support for the on-site measurement work of the geodetic instrument.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
