Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Example: Reference Figure 1-4The horizontal fixer for surveying and mapping shown in the figure comprises a base plate 1, a plurality of telescopic brackets are installed at the bottom of the base plate 1, a first fixed cylinder 2 is installed at the top of the base plate 1, a first universal ball 3 is installed at the top of the first fixed cylinder 2, an adjustment block 4 is movably installed on the first universal ball 3, a second fixed cylinder 8 is installed at the top of the adjustment block 4, a second universal ball 9 is installed at the top of the second fixed cylinder 8, a placing table 10 is movably installed on the second universal ball 9, a level ruler 19 is installed at the side of the adjustment block 4 and the front of the placing table 10, and the top of the base plate 1 and the first universal ball 9 are provided with a horizontal ruler 19. The top of the adjusting block 4 is provided with a movable groove, and two threaded blocks 6 and two moving blocks 12 are respectively arranged in the two movable grooves. The top of the two threaded blocks 6 and the top of the two moving blocks 12 are respectively rotatably installed with inclined plates 7 and connecting plates 13. The other ends of the two inclined plates 7 and the two connecting plates 13 are respectively rotatably installed on the bottom of the adjusting block 4 and the bottom of the placing table 10. The bottom plate 1 and the adjusting block 4 are respectively provided with adjusting mechanisms for moving the threaded block 6 and the moving block 12, and the top of the bottom plate 1 and the adjusting block 4 are both provided with auxiliary supporting mechanisms.
[0023] With the above structure, when in use, first place it on the ground through the telescopic bracket, and then directly observe the horizontal ruler 19 on the adjusting block 4 and the adjusting mechanism to move the threaded block 6. The movement of the threaded block 6 will change the angle of the adjusting block 4 through the inclined plate 7, and then adjust the longitudinal angle on the placement table 10. When adjusted, move the moving block 12 by directly observing the horizontal ruler 19 and the adjusting mechanism of the placement table 10. The movement of the moving block 12 will change the angle of the placement table 10 through the connecting plate 13, and then adjust the lateral angle of the placement table 10. The placement table 10 can be horizontally adjusted while observing the horizontal ruler 19, which makes the adjustment more convenient and easier to use.
[0024] like Figure 4 As shown, the adjustment mechanism includes a first screw rod 5 and a second screw rod 11 which are rotatably installed on the opposite inner walls of the two movable grooves, respectively, and a first knob and a second knob are installed on one end of the first screw rod 5 and one end of the second screw rod 11 respectively, the two threaded blocks 6 are both threadedly connected to the first screw rod 5, and the two moving blocks 12 are both threadedly connected to the second screw rod 11, and guide units are provided in the two movable grooves. The advantage of such a configuration is that the threaded block 6 and the moving block 12 can be easily moved through the configuration of the first screw rod 5, the second screw rod 11, the first knob and the second knob.
[0025] Specifically, when in use, the first knob and the second knob are rotated. The rotation of the first knob and the second knob will respectively rotate the first screw rod 5 and the second screw rod 11. The rotation of the first screw rod 5 and the second screw rod 11 will respectively move the threaded block 6 and the moving block 12, thereby adjusting the placement table 10 horizontally.
[0026] like Figure 4 As shown, the guide unit includes a guide rod 18 installed on the relative inner walls of the two movable grooves, and the sides of the two threaded blocks 6 and the sides of the two moving blocks 12 are provided with guide holes. The guide rod 18 located on the same side passes through the two guide holes in sequence. The advantage of this arrangement is that through the setting of the guide rod 18, the threaded block 6 and the moving block 12 can be moved in the horizontal direction.
[0027] like Figure 1 As shown, threaded holes are provided on the side of the base plate 1 and the side of the adjusting block 4, and fastening bolts 14 are threadedly sleeved in the two threaded holes, and the ends of the two fastening bolts 14 are respectively tightened against the first screw rod 5 and the second screw rod 11. The advantage of such a configuration is that the first screw rod 5 and the second screw rod 11 can be easily fixed through the configuration of the fastening bolts 14, and the first screw rod 5 and the second screw rod 11 are prevented from rotating and affecting the horizontal state of the placement table 10.
[0028] like Figure 4 As shown, the auxiliary support mechanism includes two telescopic rods 15 respectively installed on the top of the base plate 1 and the top of the adjustment block 4, and the ends of the four telescopic rods 15 are installed with support blocks 16, and the bottoms of the four support blocks 16 are provided with elastic units. The advantage of this arrangement is that the shaking of the adjustment block 4 and the placement table 10 can be reduced through the arrangement of the telescopic rods 15 and the support blocks 16.
[0029] Specifically, when the angle of the adjusting block 4 and the placing table 10 changes, the supporting block 16 will contact the bottom of the adjusting block 4 and the placing table 10 respectively under the action of the elastic unit and the telescopic rod 15, thereby providing auxiliary support to the adjusting block 4 and the placing table 10, thereby reducing the shaking of the adjusting block 4 and the placing table 10.
[0030] like Figure 2 As shown, the elastic unit includes a bottom spring 17 installed on the support block 16, the other ends of the two springs 17 located at the bottom are installed on the top of the base plate 1, and the other ends of the two springs 17 located at the top are installed on the top of the adjustment block 4. The advantage of this arrangement is that through the arrangement of the spring 17, it is convenient to make the support block 16 contact with the bottom of the adjustment block 4 or the placement table 10.
[0031] Specifically, when the angle of the adjustment block 4 and the placement table 10 changes, the support block 16 will be in contact with the bottom of the adjustment block 4 and the placement table 10 respectively under the action of the spring 17.
[0032] like Figure 3 As shown, the support block 16 is a semi-spherical sphere. The advantage of such a configuration is that damage to the adjustment block 4 and the bottom of the placement table 10 is avoided.
[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
