Description

Technical Field

[0001] The utility model relates to surveying and mapping equipment, in particular to a fixing device for surveying and mapping equipment. Background Art

[0002] The surveying and mapping equipment generally includes a fixing device and a surveying and mapping module (such as a level, a total station, etc.). The fixing device generally includes a mounting portion, three connecting legs and three supporting feet. The mounting portion is used to install the surveying and mapping module. The connecting legs can be extended and retracted, and the upper end can be hinged to the mounting portion in a fixed position. The supporting foot is fixedly connected to the lower end of the connecting leg, and is generally a conical support block. By unfolding the three connecting legs, the support block touches the ground as a support to fix the entire surveying and mapping equipment.

[0003] The specific use environment of surveying and mapping equipment is different, such as mud, sand, cement and shipboard. For mud, sand and other environments, because the conical support block can be inserted, the fixing effect of the entire fixing device is relatively stable. However, for cement, shipboard and other environments, because the conical support block cannot be inserted, the contact area of ​​the support block touching the ground is also very small, so the fixing effect of the entire fixing device is not stable enough. It can be seen that the fixing devices in existing surveying and mapping equipment are not enough to meet various different use environments. Utility Model Content

[0027] See also Figure 1 , a fixing device for surveying and mapping equipment, comprising: a mounting portion 1, three connecting legs 2 and three supporting feet 3.

[0028] The mounting portion 1 is used for mounting a surveying and mapping module of a surveying and mapping device, and the bottom surface of the mounting portion 1 is provided with three hinged positions.

[0029] The three connecting legs 2 have the same structure. The connecting legs 2 include an upper connecting segment 2a and a lower connecting segment 2b which is telescopically connected to the upper connecting segment 2a in a fixed position.

[0030] Specifically, the upper connecting section 2a may include: two first connecting strips 2a1 and a first connecting block 2a2 fixedly connected to the lower ends of the two first connecting strips 2a1; the lower connecting section 2b includes a second connecting strip 2b1 and a second connecting block 2b2 fixedly connected to the upper end of the second connecting strip 2b1; the first connecting block 2a2 is provided with a first through-hole position that matches the second connecting strip 2b1, and the through-hole portion of the second connecting strip 2b1 is located between the two first connecting strips 2a1; the second connecting block 2b2 is provided with a second through-hole position corresponding to each first connecting strip 2a1, and a connected threaded hole is also provided corresponding to each second through-hole position, and a first screw 2b3 that can lock and fix the second connecting block 2b2 to the first connecting strip 2a1 is threadedly connected in the threaded hole.

[0031] The upper end of the upper connecting section 2a can be hinged to the mounting portion 1 in a fixed position. Specifically, each hinge position of the mounting portion 1 can be provided with two connecting ears, and the upper end of a first connecting strip 2a1 corresponds to a connecting ear, and the two are hinged with damping by means of fasteners and gaskets.

[0032] See also Figure 2 , Figure 3 and Figure 4 The three support legs 3 have the same structure and are respectively arranged at the lower ends of the three lower connecting sections 2b. The support legs 3 include: an outer shell 3a, an insert rod 3b and a first spring 3c.

[0033] The outer shell 3a is hinged to the lower end of the second connecting strip 2b1 in the lower connecting section 2b around a horizontal first axis. One side of the outer shell 3a is a support plate 3a5 parallel to the first axis.

[0034] The insertion rod 3b slides on the outer shell 3a, and the first spring 3c is arranged between the insertion rod 3b and the outer shell 3a.

[0035] Specifically, the cavity in the outer shell 3a can be cylindrical, and the upper and lower ends are both provided with a third outlet hole 3a6 connecting to the cavity; the part of the insertion rod 3b in the outer shell can be integrally provided with a stopper 3b1 that cooperates with the cavity, and the sliding of the insertion rod 3b and the outer shell 3a is completed through the cooperation of the cavity and the stopper 3b1; the lower end of the insertion rod 3b passes through the third outlet hole 3a6 at the bottom and is fixedly connected with a conical support block 3b2; the first spring 3c is sleeved on the insertion rod 3b, and the two ends are respectively kept against the stopper 3b1 and the lower inner wall of the outer shell 3a; under the action of the first spring 3c, the support block 3b2 presses against the bottom surface of the outer shell 3a, and at this time the upper end of the insertion rod 3b passes through the third outlet hole 3a6 at the top.

[0036] See also Figure 4 and Figure 5Optionally, the outer shell 3a includes: a cylindrical first part 3a1, a second part 3a2 inserted from the top of the first part 3a1, a third part 3a3 inserted from the bottom of the first part 3a1, and two connecting sleeves 3a4. The second part 3a2 and the third part 3a3 are both provided with the third through-hole position 3a6 mentioned above, and the second part 3a2 and the third part 3a3 can be inserted and overlapped at a position close to each other, and the overlapping parts are both provided with a fourth through-hole position 3a7. The two connecting sleeves 3a4 pass through the lower connecting section 2b from both sides, enter the fourth through-hole position 3a7, and are fixedly connected to the first part 3a1. Specifically, the outer walls on both sides of the first part 3a1 can be provided with threaded holes corresponding to the fourth through-hole position 3a7, and the second screw is used to penetrate the connecting sleeve 3a4 and threadedly connected to the first part 3a1. At the same time, the first part 3a1, the second part 3a2 and the third part 3a3 are combined into the outer shell 3a and the hinge between the outer shell 3a and the lower connecting section 2b is completed. Accordingly, the support plate 3a5 can be divided into two parts, which are integrally arranged on the second part 3a2 and the third part 3a3.

[0037] The lower connecting section 2b is provided with a plug hole 2b4 for the upper end of the plug rod 3b to enter, so that under the action of the first spring 3c, the protruding portion of the upper end of the plug rod 3b enters the plug hole 2b4, limiting the rotation of the outer shell 3a relative to the lower connecting section 2b. At this time, the support foot 3 is in the first state, supported by the support block 3b2 at the lower end of the plug rod 3b, and is suitable for muddy, sandy and other environments.

[0038] Manually overcome the first spring 3c and move the rod 3b downward, so that the upper end of the rod 3b is separated from the insertion hole 2b4, and the rotation restriction of the outer shell 3a is released, and then the support foot 3 is rotated to make the support plate 3a5 of the outer shell 3a touch the ground. At this time, the support foot 3 is in the second state, with the support plate 3a5 of the outer shell 3a as support, which is suitable for environments such as cement ground and shipboard.

[0039] When the supporting foot 3 is in the first state, the supporting plate 3a5 can be located outside or inside the first axis.

[0040] See also Figure 6 Optionally, when the support foot 3 is in the first state, the support plate 3a5 of the outer shell 3a is located outside the first axis. In this way, when the support foot 3 is in the second state, the conical support block 3b2 on the lower end of the insertion rod 3b faces inward, which is not easy to be hit when passing by the surveying and mapping equipment, and is safer.

[0041] Optionally, the support plate 3a5 extends beyond the left and right sides of the outer shell 3a. Although the support plate 3a5 may extend beyond the upper and lower sides of the outer shell 3a, the extended portion at the lower side may affect the use of the lower end of the insertion rod 3b when the support foot 3 is in the first state. Therefore, it is more appropriate to increase the area of ​​the support plate 3a5 from the left and right directions to improve stability.

[0042] Furthermore, when the portion of the support plate 3a5 that exceeds the outer shell 3a abuts against the lower connecting section 2b, the insertion rod 3b and the insertion hole 2b4 are aligned. The portion of the support plate 3a5 that exceeds the outer shell 3a is used to simultaneously complete the positioning of the insertion rod 3b and the insertion hole 2b4.

[0043] Furthermore, a plurality of mounting holes 3a5a are provided on the portion of the support plate 3a5 that exceeds the outer shell 3a. In a suitable use environment, the three support legs 3 can also be fixed by screws that fit into the mounting holes 3a5a.
