Description

Technical Field

[0001] This utility model relates to a leveling mechanism, specifically a leveling locking device. Background Technology

[0002] Currently, the leveling mechanisms equipped on existing antenna turntables, portable tripods, etc., are generally single-stage coarse leveling and locking mechanisms. These mechanisms are achieved through manual buckle or screw rotation locking, resulting in poor leveling accuracy, difficult operation, and unstable fixation after leveling.

[0003] This means that while the existing coarse leveling and locking mechanisms of antenna turntables and portable tripods can meet the normal operation of equipment with low leveling requirements (greater than 0.5°), they will affect the normal operation of equipment such as antenna turntables and photoelectric tracking devices with high leveling requirements (less than 0.5°).

[0004] To address the problems of existing antenna turntables and portable tripods that can only perform coarse leveling at the first stage, which is difficult and unstable after leveling, this application proposes a new leveling and locking device. Utility Model Content

[0005] To address the problems of existing antenna turntables and portable tripods that can only perform coarse leveling at the first stage, are difficult to level, and are not stable after leveling, this utility model provides a leveling and locking device that can accurately level and quickly lock.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A leveling and locking device includes a primary leveling mechanism, a secondary leveling mechanism, and a locking mechanism; The primary leveling mechanism includes a fixed flange and leveling legs. Multiple leveling legs are evenly distributed around the fixed flange, and each leveling leg extends in the vertical direction. The lower end of the leveling leg is provided with a lower spherical joint, which is placed on the support surface. The fixed flange is provided with a primary adjustment hole at the position corresponding to the leveling leg, and the adjustment leg passes through the primary adjustment hole and is threadedly connected to it. The secondary leveling mechanism includes a leveling flange and leveling screws. The leveling flange is located above the fixed flange, and multiple leveling screws are evenly distributed around the circumference of the leveling flange, with each leveling screw extending in the vertical direction. The upper end of the leveling screw is provided with an upper spherical joint, which is fixedly connected to the leveling flange. The fixed flange is provided with a secondary adjustment hole at a position corresponding to the leveling screw, through which the leveling screw passes and is threadedly connected. The locking mechanism includes a locking screw, a central spherical seat fixed at the center of the leveling flange, an upper ball head at the upper end of the locking screw, the locking screw passing through the central spherical seat and extending downward, and the upper ball head forming a spherical fit with the central spherical seat; a locking hole is provided on the fixed flange at a position corresponding to the locking screw, the locking screw passing through the locking hole and threadedly connected to it.

[0007] Furthermore, a nut seat is fixedly provided at the primary adjustment hole. The nut seat has a self-locking internal thread, and the leveling leg has a self-locking external thread. The leveling leg passes through the nut seat and is threadedly connected to it.

[0008] Furthermore, the lower end of the leveling screw is located below the fixed flange, and a horizontal fixing hole is provided at the lower end of the leveling screw, in which an anti-loosening screw is installed.

[0009] Furthermore, a support flange is fixedly provided on the lower side of the lower spherical joint.

[0010] Furthermore, the lower side of the leveling flange is provided with an installation groove corresponding to the upper spherical joint. The upper spherical joint is placed in the installation groove, and a spherical joint cover plate is fixed at the opening of the installation groove to fix the upper spherical joint.

[0011] Furthermore, the leveling screw and leveling support legs are arranged in an alternating pattern on the plane projection.

[0012] Furthermore, a locking handle is provided at the lower end of the locking screw.

[0013] Furthermore, the leveling flange has a pre-reserved interface for the load.

[0014] Furthermore, the maximum deflection angle of the lower spherical joint is 15°.

[0015] Furthermore, the maximum deflection angle of the upper spherical joint is 8°.

[0016] The beneficial effects of this utility model are: 1. This utility model features a two-stage leveling function. The fixed flange is leveled firstly using leveling legs, and then the leveling flange is leveled secondarily using leveling screws. The combined use of these two adjustment stages ensures more precise and accurate adjustment. After leveling, the fixed flange and leveling flange are connected and secured using locking screws, ensuring the stability of the equipment between the two flanges.

[0017] 2. This utility model can accurately level and quickly lock, and can be completed by a single person.

To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example 1: like Figures 1 to 3 As shown, this embodiment provides a leveling and locking device, including a primary leveling mechanism, a secondary leveling mechanism, and a locking mechanism.

[0025] The primary leveling mechanism includes a fixed flange 4 and three leveling legs 3. The three leveling legs 3 are evenly distributed around the fixed flange 4, and each leveling leg 3 extends vertically. The lower end of the leveling leg 3 is equipped with a lower spherical joint, which can be omnidirectionally deflected with a maximum deflection angle of 15°. This ensures that the leveling leg 3 remains perpendicular to the ground in real time and that the force is evenly distributed.

[0026] A support flange 10 is fixedly provided on the lower side of the lower spherical joint 9. The support flange 10 has a large area and can be placed on the ground or connected to the support surface of the equipment through the support flange 10.

[0027] The fixed flange 4 is provided with a primary adjustment hole at the position corresponding to the leveling leg 3. The leveling leg 3 passes through the primary adjustment hole and is threadedly connected to it.

[0028] The specific cooperation method between the adjusting leg 3 and the first-stage adjusting hole is as follows: a nut seat 11 is fixedly provided at the first-stage adjusting hole. The nut seat 11 has a self-locking internal thread, and the leveling leg 3 has a self-locking external thread. The leveling leg 3 passes through the nut seat 11 and is threadedly connected to it.

[0029] The secondary leveling mechanism includes a leveling flange 6 and leveling screws 5. The leveling flange 6 is located above the fixed flange 4. Three leveling screws 5 are evenly distributed around the circumference of the leveling flange, and each leveling screw 5 extends vertically. The upper end of each leveling screw 5 is equipped with an upper spherical joint 2, which is fixedly connected to the leveling flange 6. The upper spherical joint 2 can rotate in all directions, with a maximum rotation angle of 8°.

[0030] The specific installation method of the upper spherical joint 2 at the leveling flange 6 is as follows: The lower side of the leveling flange 6 is provided with an installation groove corresponding to the position of the upper spherical joint 2. The upper spherical joint 2 is placed in the installation groove, and a spherical joint cover plate 1 is fixed at the opening of the installation groove to fix the upper spherical joint 2.

[0031] The fixed flange 4 has a secondary adjustment hole corresponding to the leveling screw 5. The leveling screw 5 passes through the secondary adjustment hole and is threaded to it. A horizontal fixing hole 12 is provided at the lower end of the leveling screw 5. An anti-loosening screw is installed in the fixing hole 12. Both the fixing hole and the anti-loosening screw are located below the fixed flange 4, which prevents the leveling screw 5 from unscrewing when rotated in the opposite direction.

[0032] The locking mechanism includes a locking screw 7. A central spherical seat 13 is fixedly provided at the center of the leveling flange 6. The upper end of the locking screw 7 is provided as an upper ball head. The locking screw 7 passes through the central spherical seat and extends downward, and the upper ball head and the central spherical seat 13 form a spherical fit. A locking hole is provided on the fixed flange 4 at a position corresponding to the locking screw 7. The locking screw 7 passes through the locking hole and is threadedly connected to it.

[0033] To ensure structural stability, the three leveling screws 5 and the three leveling legs 3 are arranged in an alternating pattern on the plane projection.

[0034] To facilitate load installation, the leveling flange 6 has a reserved interface for the load. The interface size can be changed according to the size of the support platform. By changing the interface size, it can be applied to various equipment such as vehicle-mounted antenna turntables, vehicle-mounted optoelectronic turntables, vehicle-mounted radar turntables, portable antenna turntables, and portable tripods, achieving multiple purposes.

[0035] For ease of operation, a locking handle 8 is provided at the lower end of the locking screw. The locking handle 8 can be designed to be manual or electric.

[0036] The working principle of this utility model is as follows: This utility model features a two-stage leveling function. The fixed flange 4 is leveled firstly via the leveling support leg 3, with a maximum leveling angle of 15°. The leveling flange 6 is leveled secondarily via the leveling screw 5, with a maximum leveling angle of 8°. The combined use of these two adjustment structures achieves a maximum adjustment accuracy of 0.05°. After leveling, the fixed flange 4 and the leveling flange 6 are connected and fixed via the locking screw 7, achieving rapid locking and ensuring the stability of the equipment between the two flanges.

[0037] The specific operation process is as follows: Rotate the three leveling legs 3, and the external thread of the leveling legs 3 will move relative to the fixed flange 4, so that the upper surface of the fixed flange 4 will be quickly leveled. The leveling legs 3 will be locked by the self-locking threads to complete the first leveling and locking, and the leveling accuracy can reach 0.1°.

[0038] Loosen the locking screw 7 and rotate the three evenly distributed leveling screws 5. The leveling screws 5 and the fixed flange 4 move relative to each other, causing the leveling flange 6 to level quickly and accurately. After leveling, rotate the locking screw 7 so that the upper spherical surface of the locking screw 7 is in close contact with the spherical hole of the central spherical seat 13 on the leveling flange 6. The lower end of the locking screw 7 is tightly connected to the fixed flange 4 via threads, thus achieving rapid locking and completing the second stage of leveling and locking. The leveling accuracy can reach 0.05°.

[0039] Example 2: The difference between this embodiment and embodiment one is that the nut seat 11 is no longer provided at the first-level adjustment hole, and a self-locking internal thread is directly provided in the first-level adjustment hole. The leveling leg 3 has a self-locking external thread, and the leveling leg 3 is directly threadedly connected to the first-level adjustment hole.
