Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

Referring to Figures 1-3, a tower ruler placement seat for land resources surveying and mapping includes a mounting seat 1, a clamping slot 2 is provided on the mounting seat 1, and two horizontal bubbles 3 that are perpendicular to each other are horizontally arranged on the mounting seat 1 , and around the mounting base 1 is provided with a number of support feet 4 whose lengths can be telescopically adjusted.

When using, support the foot 4 on the ground, and then adjust the foot 4 to extend and retract to make the mounting seat 1 in a horizontal state. During the adjustment process, we can use the horizontal bubble 3 as an adjustment reference, and we can first adjust a horizontal bubble 3 to be in a horizontal state. , and then put another horizontal bubble 3 in a horizontal state, so that the mounting base 1 is horizontal. At this time, we place the tower ruler 13 in the slot 2, and naturally place the tower ruler 13 vertically.

For ease of use, the support feet 4 are provided to swing up and down.

In order to facilitate adjustment during use, there are three supporting feet 4 distributed around the circumference of the mounting base 1 , and one of the horizontal bubbles 3 is parallel to the connection line where two of the supporting feet 4 are connected with the mounting base 1 . This allows you to adjust two of them first, and then adjust the other one.

In order to facilitate the fixing of the tower ruler 13, the card slot 2 is a C-shaped card slot with an upward opening. We can set a convex portion 14 at the bottom end of the tower ruler 13 that fits with the card slot 2, so that when the tower ruler 13 is placed It is enough to directly snap the convex portion 14 into the card slot 2 .

Further, the support foot 4 includes a swing arm 5, one end of the swing arm 5 is hinged with the mounting seat 1, and the other end of the swing arm 5 is provided with a support rod 6 sliding along the length direction of the swing arm 5, the support rod 6 and The top of the connecting end of the swing arm 5 is provided with a rack 7 , the swing arm 5 is provided with a rotatable rotating shaft 8 , and a gear 9 is coaxially arranged on the rotating shaft 8 to mesh with the rack 7 . A first knob 10 is fixed on the rotating shaft 8 . In this way, the purpose of extending and retracting the adjusting leg 4 can be achieved by rotating the rotating shaft 8, wherein the first knob 10 can increase the contact area between the hand and the rotating shaft 8, and has the effect of saving labor.

In addition, the swing arm 5 is provided with a through hole opposite to the strut 6 , the through hole is provided with an internal thread, and the screw rod 11 is arranged to pass through the through hole and be threadedly connected with it. A second knob 12 is fixed on the end of the screw 11 opposite to the support rod 6 . After the adjustment, the support rod 6 can be further tightened by the screw 11 to achieve the purpose of further fixing, and the end of the support rod 6 is provided with a pointed part, which is more convenient for placing the support feet by using the pointed part to contact the ground.

The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited to this. Equivalent replacement or modification of the new technical solution and its utility model concept shall be included within the protection scope of the present utility model.
