Detailed Description
The utility model is further described below with reference to the accompanying drawings.
Examples: an automatic tripod leveling device for instrument erection, see fig. 1, comprises a connecting seat 1, a rotating block 2 hinged at the bottom end of the connecting seat 1, supporting legs 3 in threaded connection with the rotating block 2, a supporting plate 4 arranged above the connecting seat 1, leveling bolts 5 in threaded connection with the supporting plate 4 and a connecting block 6 arranged at the top end of the supporting plate 4.
The bottom of connecting seat 1 is fixed with link 11, and link 11 rotates with turning block 2 to be connected, realizes the articulated between turning block 2 and the connecting seat 1. The upper surface of the connecting seat 1 and the upper surface of the supporting plate 4 are both provided with balance bubbles 12, and whether the connecting seat 1 and the supporting plate 4 are in a horizontal position can be known by observing the balance bubbles 12.
Threaded connection between supporting leg 3 and rotating block 2, conveniently change supporting leg 3, can be to different work
The environment selects the supporting legs 3 with different lengths, and the use is more flexible. The supporting leg 3 comprises a connecting sleeve 31 in threaded connection with the rotating block 2, an adjusting rod 32 in threaded connection with one end of the connecting sleeve 31 far away from the rotating block 2, and a supporting leg 33 hinged with one end of the adjusting rod 32 far away from the connecting sleeve 31. The feet 33 are intended to contact the ground and increase the contact area with the ground, thereby increasing the stability of the support leg 3 during support.
When the supporting leg 3 is completely unfolded, the connecting seat 1 is horizontally adjusted according to the balance bubble 12 positioned on the connecting seat 1, namely, the whole length of the supporting leg 3 is adjusted by rotating the adjusting rod 32, so that the horizontal position of the connecting seat 1 is adjusted. (this adjustment is of coarse tuning).
Referring to fig. 2 and 3, a positioning assembly 13 for positioning the rotating block 2 after rotation is provided on the connection frame 11. The rotating block 2 is provided with a first positioning groove 21 and a second positioning groove 22 which are matched with the positioning assembly 13, and the surfaces of the first positioning groove 21 and the second positioning groove 22 are arc surfaces. After the rotating block 2 rotates, the first positioning groove 21 or the second positioning groove 22 can be matched with the positioning assembly 13. When the positioning assembly 13 is matched with the first positioning groove 21, the supporting leg 3 is in a storage state; when the positioning assembly 13 is engaged with the second positioning groove 22, the support leg 3 is in a released state.
The connecting frame 11 is provided with a containing groove 111, and the positioning component 13 is arranged in the containing groove 111. The positioning assembly 13 comprises a connecting plate 131 fixedly connected with the connecting frame 11, a spring 132 arranged in the accommodating groove 111 and a positioning ball 133 arranged at one end of the spring 132 far away from the connecting plate 131.

Since the surfaces of the positioning ball 133, the first positioning groove 21 and the second positioning groove 22 are arc surfaces, the positioning ball 133 can slide out of the first positioning groove 21 and the second positioning groove 22 when the positioning ball 133 is relatively displaced from the first positioning groove 21 and the second positioning groove 22. When the positioning ball 133 is placed in the first positioning groove 21 and the second positioning groove 22, and is wanted to slide out from the first positioning groove 21 and the second positioning groove 22, a resistance exists due to the action of the spring 132, so that a user is prompted to reach a preset positioning position, and the positioning of the rotating block 2 after rotation is realized.
Referring to fig. 4, the connection socket 1 is provided with a connection ball 41 at one side thereof adjacent to the support plate 4, and the connection ball 41 is rotatably connected in the connection socket 1 and partially exposes the connection socket 1. The support plate 4 is fixedly connected with the portion of the connecting ball 41 exposed out of the connecting seat 1, so that connection between the connecting seat 1 and the support plate 4 is realized, and the support plate 4 can rotate relative to the connecting seat 1 (the support plate 4 rotates in a direction approaching to or separating from the connecting seat 1).
One side fixedly connected with that connecting block 6 is close to backup pad 4 with backup pad 4 threaded connection's spliced pole realizes dismantling between connecting block 6 and the backup pad 4 and is connected, is convenient for change connecting block 6 to realize setting up different check out test set.
The number of the leveling bolts 5 is at least three, and is uniformly arranged along the circumferential direction of the support plate 4. When the support plate 4 needs to be leveled, the leveling bolts 5 at different positions are rotated according to the balance bubbles arranged on the support plate 4, so that the adjustment of the support plate 4 is realized (the adjustment belongs to fine adjustment).
The adjustment of the level of the connecting seat 1 and the supporting plate 4 is respectively realized by adjusting the length of the supporting leg 3 and rotating the leveling bolt 5, so that the level of the tripod is adjusted.
In the description of the present utility model, it should be noted that the azimuth or positional relationship indicated by the terms "front end", "rear end", "left and right", "up", "down", "horizontal", etc. is based on the azimuth or positional relationship shown in the drawings, and is only for convenience of description and simplification of description, and is not limiting of the present utility model.
