Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping technology, specifically to a support for surveying and mapping engineering. Background Technology

[0002] Surveying engineering involves measuring various information about space and the earth and drawing various topographic maps. It studies the shape, size, and gravitational field of the earth and other planets. The objects of study and surveying are very extensive, mainly including various land features and landforms on the earth's surface and underground geological structures, hydrology, minerals, etc., such as mountains, rivers, houses, roads, vegetation, etc. A surveying support is an indispensable auxiliary device in surveying engineering work. Surveying instruments are set up on surveying supports at the surveying location to facilitate the use of surveying instruments.

[0003] Existing support structures are not easy to carry and can burden surveyors. Since the fixed legs at the bottom of the support are usually cone-shaped and fixed, they cannot be folded up. When going to the surveying point, the support needs to be carried, but the support is prone to swinging when people walk, which can cause the cone-shaped legs at the bottom of the support to prick people. This can easily cause injury when carrying the support, reduce safety, and make it inconvenient to use.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a support for surveying engineering.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a support for surveying engineering, including a mounting platform, a fixed base fixedly connected to the bottom of the mounting platform, a sleeve hinged to the bottom of the fixed base, a support leg slidably connected to the bottom of the sleeve, and a fixed support leg fixedly connected to the bottom of the support leg, characterized in that:

[0007] The protective structure is located at the bottom of the support leg. The protective structure includes a U-shaped shield at the bottom of the support leg. Rotating rods are fixedly connected to the upper parts of both ends of the inner wall of the U-shaped shield. A through hole is opened at the lower end of the support leg. The rotating rods are rotatably connected to the through hole. The U-shaped shield is used in conjunction with the fixed support leg.

[0008] A limiting structure is provided on the protective structure. The limiting structure includes a cavity opened at the upper part of one end of a U-shaped shield. A limiting rod is slidably connected inside the cavity. A limiting groove is opened at the lower end of one side of the support foot. There are several limiting grooves distributed circumferentially around the through hole. One end of the limiting rod extends to the inside of the U-shaped shield and is engaged in the limiting groove. The other end of the limiting rod extends to the outside of the U-shaped shield and is fixedly connected to a pull ring plate. A pressure plate is fixedly connected to one end of the limiting rod inside the cavity. A spring is fixedly connected between the pressure plate and the other end of the cavity wall. The spring is sleeved on the outside of the limiting rod.

[0009] Furthermore, there are three fixed bases arranged in a circle around the mounting platform.

[0010] Furthermore, a positioning bolt is threaded to the lower end of one side of the outer wall of the sleeve, and a positioning groove is provided on one side of the outer wall of the support foot. There are several positioning grooves and they are evenly spaced. The positioning bolt is used in conjunction with the positioning groove.

[0011] Furthermore, a guide groove is provided at one end of the inner wall of the sleeve, and a guide block is fixedly connected to the top end of the support foot, with the guide block slidably connected within the guide groove.

[0012] Furthermore, the bottom of the U-shaped shield is fixedly connected with a self-locking universal wheel.

[0013] The advantages of this utility model compared with the prior art are as follows: Through the setting of the protective structure and the limiting structure, when it is necessary to move and carry the bracket, by pulling the pull ring plate outward, the limiting rod is driven to disengage from the limiting groove. At this time, the limiting rod drives the pressure plate to move inside the cavity and squeezes the spring. Then, the U-shaped shield is rotated to the bottom of the support foot, and then the pull ring plate is released. The spring returns to its original position and retracts, so that the limiting rod is inserted into the corresponding limiting groove. This allows the cone-shaped fixed foot to be stored inside the U-shaped shield, thereby preventing the fixed foot from poking people or objects during the carrying of the bracket. At the same time, after the U-shaped shield is lowered, it is easy to move the self-locking universal wheels to the bottom of the bracket, making it easy to move the bracket in the surveying area. It is more convenient to use, improves the safety and convenience of the bracket, and enhances the practicality of the bracket. Attached Figure Description

A damping rotating shaft structure is provided between the fixed base 2 and the sleeve 3. This is existing technology and will not be described in detail here. When there is no external force pulling between the fixed base 2 and the sleeve 3, the sleeve 3 will not rotate relative to the fixed base 2, so that the sleeve 3 can provide stable support for the bracket.

[0024] A positioning bolt 31 is threaded to the lower end of one side of the outer wall of the sleeve 3. A guide groove 32 is provided at one end of the inner wall of the sleeve 3. A positioning groove 41 is provided on one side of the outer wall of the support foot 4. There are several positioning grooves 41 and they are evenly spaced. The positioning bolt 31 is used in conjunction with the positioning groove 41. A guide block 42 is fixedly connected to the top end of the support foot 4. The guide block 42 is slidably connected in the guide groove 32. The positioning bolt 31 and the positioning groove 41 facilitate the adjustment of the height and level of the bracket. The guide groove 32 and the guide block 42 facilitate the limiting and guiding of the movement of the support foot 4 inside the sleeve 3.

[0025] The bottom of the support leg 4 is fixedly connected to a fixed support leg 5, wherein the fixed support leg 5 is cone-shaped.

[0026] The bottom of the support leg 4 is provided with a protective structure 6. The protective structure 6 includes a U-shaped shield 61 located at the bottom of the support leg 4. The upper part of both ends of the inner wall of the U-shaped shield 61 is fixedly connected to a rotating rod 62. The lower end of the support leg 4 is provided with a through hole 63. The rotating rod 62 is rotatably connected to the through hole 63. The U-shaped shield 61 is used in conjunction with the fixed support leg 5. By rotating the U-shaped shield 61 to the bottom of the support leg 4, the U-shaped shield 61 is parallel to the support leg 4, so that the U-shaped shield 61 can cover and store the fixed support leg 5 inside, preventing the fixed support leg 5 from piercing people when carrying the support.

[0027] The protective structure 6 is provided with a limiting structure 7, which includes a cavity 71 opened at the upper part of one end of the U-shaped shield 61. A limiting rod 72 is slidably connected inside the cavity 71. A limiting groove 73 is opened at the lower end of one side of the support leg 4. There are several limiting grooves 73, which are distributed circumferentially around the through hole 63.

A spring 75 is fixedly connected between the pressure plate 74 and the other end of the inner wall of the cavity 71. The spring 75 is sleeved on the outside of the limiting rod 72. Through the cooperation of the limiting rod 72 and several limiting grooves 73, it is convenient to limit and fix the angle of the U-shaped shield 61 after rotation, thereby improving the convenience of the bracket.

[0028] The bottom of the U-shaped shield 61 is fixedly connected to a self-locking caster wheel 8. The self-locking caster wheel 8 is existing technology and will not be described in detail here.

[0029] In practical implementation, when the support needs to be moved or carried, first pull the pull ring plate 76 outward. The pull ring plate 76 will drive the limiting rod 72 outward from the inside of the limiting groove 73. At this time, the limiting rod 72 drives the pressure plate 74 to move inside the cavity and squeeze the spring 75. Then, rotate the U-shaped shielding frame 61 downward. When the U-shaped shielding frame 61 rotates to the bottom end of the support leg 4, the U-shaped shielding frame 61 is parallel to the support leg 4, and the U-shaped shielding frame 61 covers and stores the fixed support leg 5 inside. Then, release the pull ring plate 76, and the spring 75... 5. Reset and retract, so that the limiting rod 72 is inserted into the corresponding limiting groove 73, so that the cone-shaped fixed support 5 is closed inside the U-shaped shield 61, preventing the fixed support 5 from piercing people when carrying the bracket. This can prevent the fixed support 5 from piercing people or objects during the carrying of the bracket. At the same time, after the U-shaped shield 61 is lowered, it is easy to move the self-locking universal wheel 8 to the bottom of the bracket, making it easy to move the bracket in the surveying area. It is more convenient to use, improves the safety and convenience of the bracket, and enhances the practicality of the bracket.
