[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] Reference Figures 1 to 6 This utility model provides a portable adjustable tripod, including: a base 1, multiple legs 2, support rods 3, multiple connecting rods 4 and multiple leveling mechanisms 5. The base 1 is used to install equipment. In this embodiment, the base 1 of the tripod is mainly used to install radar. In actual use, the size of the base 1 can be adjusted according to the different installation interfaces of the radar equipment, so as to adapt to the installation of different radar equipment.

[0031] The base 1 is hinged to one end of multiple support legs 2 in the circumferential direction. The support legs 2 provide support. In this embodiment, three support legs 2 are provided to bear the load. A level is also provided on the side wall of the base 1 to check whether the tripod is level.

[0032] One end of the support rod 3 is connected to the bottom of the base 1, and the other end of the support rod 3 is provided with a hook 7. The hook 7 is used to suspend the radar's supporting equipment, such as power supply and processing chassis.

[0033] One end of each of the multiple connecting rods 4 is slidably connected to the support rod 3, and the other end is connected to the support leg 2. The multiple connecting rods 4, the support rod 3, and the multiple support legs 2 cooperate to set up the tripod. Specifically, a sliding sleeve 6 is fitted on the support rod 3, and the sliding sleeve 6 is hinged to one end of the multiple connecting rods 4 in the circumferential direction. Each support rod 202 is fitted with a fixing sleeve 8, and each fixing sleeve 8 is hinged to the other end of the connecting rod 4. When it is necessary to spread the tripod for installation, the sliding sleeve 6 is slid along the support rod 3 towards one end of the hook 7. The sliding sleeve 6 drives one end of the connecting rod 4 to move, so that the included angle between the connecting rod 4 and the support rod 3 increases, thereby spreading the support rod 3 and the support leg 2 to ensure that the tripod can stand stably on the ground.

[0034] Each support leg 2 is equipped with a leveling mechanism 5 at the end away from the base 1. The leveling mechanism 5 is used to adjust the base 1 to a horizontal position.

[0035] To better implement this utility model, refer to Figure 3In one embodiment, each leveling mechanism 5 includes a guide cylinder 509, a sleeve 505, a handle 501, a lead screw 503, a bearing 504, a sealing ring 502, a rotating rod 507, and a base 506. The lower end of the guide cylinder 509 is connected to the base 506. The sleeve 505 is fitted onto the guide cylinder 509 from the upper end. The guide cylinder 509 has a lead screw 503 inside, and the external thread of the lead screw 503 engages with the internal thread on the inner wall of the guide cylinder 509. The upper end of the screw 503 is connected to one end of the rotating rod 507. A sealing ring 502 is provided between the upper opening of the sleeve 505 and the rotating rod 507. The sealing ring 502 is made of fluororubber skeleton oil seal with high elasticity and resilience. The coefficient of friction between the fluororubber skeleton oil seal and the rotating rod 507 is between 0.05 and 0.15. In addition, grease is applied to the surface of the lead screw 503 to ensure that the rotating rod 507 and the sealing ring 502 will not wear during the tripod leveling process, thus extending the service life. The end of the rotating rod 507 away from the lead screw 503 is connected to the handle 501. The lower end of the lead screw 503 is fitted with a bearing 504. The handle 501 can be connected to the rotating rod 507 through a horizontal short rod. The handle 501 is hinged to the short rod. When the handle 501 is not in use, it can be rotated to adjust the handle 501 to a state that is parallel to the rotating rod 507, making it convenient to rotate the leveling mechanism 5 into the folding bracket 201. The diameter of the lead screw 503 is larger than that of the rotating rod 507, ensuring that the lead screw 503 will not detach from the connection between the sleeve 505 and the rotating rod 507 during rotation. Furthermore, the upward movement of the lead screw 503 during rotation can drive the sleeve 505 upward. Because a sealing ring 502 exists between the sleeve 505 and the rotating rod 507, the rotation of the rotating rod 507 will not cause the sleeve 505 to rotate. A limiting block can also be provided at the connection between the lead screw 503 and the rotating rod 507. The limiting block abuts against the top of the sleeve 505, so that when the external thread of the lead screw 503 engages with the internal thread of the guide cylinder 509, the lead screw 503 rotates and moves upward along the guide cylinder 509. The lead screw 503 and the rotating rod 507 rotate, but the relative rotation between the rotating rod 507 and the sleeve 505 due to the sealing ring 502 does not cause the sleeve 505 to rotate. The sleeve 505 only moves upward due to the limiting block.

[0036] To prevent the rotating rod 507 from causing the sleeve 505 to rotate, multiple limiting grooves are provided on the outer side wall of the guide cylinder 509 along the axial direction, and a limiting strip is provided on the inner wall of the sleeve 505. The limiting strip is installed in the limiting groove to restrict the rotation of the sleeve 505, so that the sleeve 505 can only move up and down along the guide cylinder 509 with the rotating rod 507.

[0037] When leveling the base 1, rotate the handle 501. The handle 501 drives the rotating rod 507 to rotate, which in turn drives the lead screw 503 to rotate. A T-shaped thread is provided on the lead screw 503, and a matching internal thread is provided on the inner wall of the sleeve 505. The T-shaped thread has high load-bearing capacity and anti-loosening performance.

[0038] To better implement this utility model, refer to Figure 5 In one embodiment, each base 506 is provided with multiple mounting holes 508, and ground stakes are installed in the mounting holes 508 to fix the tripod to the ground. In this embodiment, each base 506 is provided with two mounting holes 508, and ground stakes are installed in each mounting hole 508. When the tripod is installed, the ground stakes are inserted into the ground to increase the tripod's wind resistance.

[0039] To better implement this utility model, refer to Figure 1 In one embodiment, each support leg 2 includes a folding bracket 201 and a support rod 202. One end of the support rod 202 is hinged to the base 1, and the other end of the support rod 202 is connected to one end of the folding bracket 201. The other end of the folding bracket 201 is open and hinged to the sleeve 505. The leveling mechanism 5 can be accommodated inside the folding bracket 201. The folding bracket 201 is U-shaped and includes a bottom and two side plates. The bottom is connected to the support rod 202, and the two side plates are hinged to the sleeve 505, allowing the entire leveling mechanism 5 to rotate between the two side plates.

[0040] To better implement this utility model, refer to Figure 1 In one embodiment, the position of the sliding sleeve 6 on the support rod 3 is limited by a limiting component. To prevent the tripod from becoming unstable due to the upward movement of the sliding sleeve 6 after the tripod is extended, a limiting component is used to limit the position of the sliding sleeve 6 on the support rod 3.

[0041] The limiting component can be a snap-fit ​​type, a threaded tightening type, or a spring pin type. In this embodiment, the threaded tightening type is used as an example. An external thread is provided on the support rod 3, and a nut is provided on the upper side of the sliding sleeve 6. The nut is sleeved on the support rod 3, and the internal thread of the nut engages with the external thread of the support rod 3. The external thread on the support rod 3 does not affect the movement of the sliding sleeve 6 on the support rod 3. When the sliding sleeve 6 moves to the appropriate position, the nut is rotated so that the nut abuts against the sliding sleeve 6, preventing the sliding sleeve 6 from sliding. More preferably, nuts can be provided on both the upper and lower sides of the sliding sleeve 6, and the nuts on the upper and lower sides sleeved on the support rod 3 can limit the sliding sleeve 6.

[0042] Based on the aforementioned portable adjustable leveling tripod, its working principle is as follows:

[0043] When the tripod is not in use, the tripod as a whole is in a certain position. Figure 6In the tripod's initial state, when using the tripod, first move the sliding sleeve 6 towards the hook 7. The sliding sleeve 6 drives the connecting rod 4 to spread the three legs 2. Rotate the leveling mechanism 5 out of the folding bracket 201. Insert the ground nails into the ground. Since the ground where the tripod is installed may be uneven, it is necessary to level the tripod using the leveling mechanism 5. Open the handle 501 and rotate it. The handle 501 drives the rotating rod 507 and the lead screw 503 to rotate. The external thread of the lead screw 503 engages with the internal thread of the guide cylinder 509, causing the lead screw 503 to move upward. This, in turn, drives the rotating rod 507 and the sleeve 505 to move upward. The movement of the sleeve 505 causes the folding bracket 201 and the support rod 202 to move, thereby adjusting the height of the base 1. Adjust the three adjustment mechanisms according to the actual usage until the level on the base 1 is horizontal. At this point, the tripod installation is complete. Figure 5 As shown, the position of the sliding sleeve 6 is limited by the limiting component, the radar is installed on the base 1, the radar's supporting equipment is suspended on the hook 7, and the entire radar is installed using a tripod.

[0044] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
