DETAILED DESCRIPTION

[0032] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0033] Please refer to Figure 1-Figure 11 To achieve the above purpose, the technical solution of the utility model is: to provide an information collection device suitable for multiple terrains, including a chassis 120, the side of the chassis 120 is provided with an axis hole 130, and also includes:

[0034] The external thread 31 is coaxially disposed on the first surface 1201 of the chassis 120;

[0035] an annular groove 1202, arranged on the first surface 1201 around the external thread 31;

[0036] A guide through hole 34 is provided on the outer peripheral surface of the chassis 120 and communicated with the annular groove, the axis of the guide through hole intersects and is perpendicular to the shaft hole, and an extrusion column 32 is provided in the guide through hole for guidance, and the extrusion column 32 includes an arc-shaped friction surface 320 provided at one end close to the shaft hole and an extrusion end 321 extending into the annular groove;

[0037] The extrusion sleeve 33 is threadedly connected to the external thread 31 , and an extrusion cone surface 331 adapted to the extrusion end is provided between the bottom surface and the outer peripheral surface of the extrusion sleeve 33 .

[0038] Specifically, in actual use, the chassis is connected to the sleeve, and the sleeve is also provided with an insertion rod and a ground pile. The surveying and mapping component is arranged on the top of the insertion rod. The specific structure, connection method and use method of the sleeve, insertion rod and ground pile are consistent with the background technology, and their structures will not be described one by one here.

[0039] refer to Figure 10-12 When in use, the extrusion column 32 is inserted into the guide through hole 34, and then the rotating shaft 220 of the support assembly 200 is set in the shaft hole 130, so that the friction surface 320 faces the rotating shaft 220, and the extrusion sleeve 33 is installed on the external thread 31. At this time, the extrusion cone surface 331 does not squeeze the extrusion end 321 of the extrusion column 32, and the friction surface 320 does not contact the rotating shaft 220. The support assembly 200 can swing at this time. When it needs to be placed on the slope, first adjust the support assembly 200 according to the slope of the slope. After adjustment, the extrusion sleeve 33 is rotated, and the extrusion sleeve is screwed into the annular groove. The extrusion cone surface 331 squeezes the extrusion end 321 outward, so that the extrusion column moves outward, so that the friction surface 320 contacts the outer peripheral surface of the rotating shaft 220, and contacts and rubs with the rotating shaft, so that the rotating shaft can be effectively locked to ensure the support stability.

[0040] Specifically, refer to Fig.12The structure and use method of the support assembly 200 are consistent with those in the background technology, and also include a sleeve 210, a rotating shaft 220, an insert plate 230 and a connecting hole 240. The difference from the background technology is that in the present application, the portion of the rotating shaft 220 extending out of the sleeve 210 is longer, thereby ensuring cooperation with the friction surface 320.

[0041] Furthermore, the end of the extrusion column 32 is connected to a rectangular extrusion piece 323 , the friction surface 320 is arranged on a side of the extrusion piece 323 away from the extrusion column 32 , and the end of the guide through hole 34 is provided with a rectangular channel 341 that cooperates with the extrusion piece 323 for guidance.

[0042] Specifically, by setting a rectangular channel and guiding the extrusion piece 323, the rectangular extrusion piece cannot rotate in the rectangular channel, thereby ensuring that the arc-shaped friction surface 320 can adapt to the outer circumference of the rotating shaft, and avoiding the problem that the axis of the friction surface intersects with the axis of the rotating shaft due to the rotation of the extrusion column, thereby causing the friction surface to fail to fully fit with the outer circumference of the rotating shaft 220.

[0043] Furthermore, at least three notches 1203 are evenly spaced on the outer circumference of the chassis 120 , and shaft holes 130 are provided on two opposite side surfaces of the notches, and at least one shaft hole provided in each notch corresponds to the guide through hole 34 .

[0044] As a specific implementation method, refer to Figure 5 The chassis 120 is provided with three notches, and axial holes 130 are provided on the two opposite sides of the notches, so that a support assembly 200 is provided in each notch. The three support assemblies 200 can improve the support stability. By providing a guide through hole 34 on at least one of the axial holes, an extrusion column is provided in the guide through hole 34, thereby ensuring that each support assembly 200 is effectively locked.

[0045] As a preferred embodiment, the two axial holes 130 corresponding to each notch are both provided with guide through holes 34 , and extrusion columns 32 are both provided in the guide through holes. The two extrusion columns can achieve a better locking effect on the support assembly.

[0046] Specifically, refer to Figure 2-Figure 5 , Fig.10 The chassis 120 is provided with removable pressure plates 1205 on both sides of the notch 1203, wherein half of the shaft hole 130 is arranged on the pressure plate 1205, and the pressure plate 1205 is connected to the chassis 120 by a locking bolt 1206. Through this arrangement, the pressure plate can be removed from the chassis, and the rotating shaft 220 of the support assembly 200 can be arranged in half of the shaft hole 130, and then the pressure plate can be installed on the chassis 120, thereby facilitating the disassembly and installation of the support assembly 200.

[0047] Furthermore, a connecting tube 3 is coaxially arranged in the middle area of ​​the chassis 120 , the connecting tube 3 passes through the chassis, and the external thread 31 is arranged on the outer peripheral surface of the connecting tube 3 .

[0048] Specifically, refer to Figure 3 , Figure 4 By setting the connecting tube through the chassis, the sleeve (not shown in the figure) can be inserted into the connecting tube, so as to achieve a better connection effect.

[0049] Further, as a specific implementation, a sleeve (not shown in the figure) is inserted in the connecting tube 3, and the sleeve is detachably connected to the connecting tube. By providing the connecting tube, the sleeve and the connecting tube are conveniently plugged in and matched to form a detachable connection. This method is convenient for replacing the sleeve and for maintenance. Specifically, an internal thread can be provided in the connecting tube, and an external thread can be provided in the connecting tube, so as to realize a detachable fixed connection between the two.

[0050] Furthermore, at least one countersunk threaded hole 311 is provided on the side wall of the connecting tube 3, and a locking bolt for locking the sleeve is connected to the inner thread of the countersunk threaded hole. Figure 4 , Figure 5 A countersunk threaded hole 311 is provided on the side wall of the connecting tube so that after the sleeve is inserted into the connecting tube, the sleeve can be locked by a locking bolt. This method has low manufacturing cost and is simple and convenient to use.

[0051] Furthermore, the connecting tube 3 and the chassis 120 are integrally formed.

[0052] Specifically, as a preferred embodiment, the connecting tube and the chassis 120 are formed by integral turning, which is easy to process and has a high connection strength between the connecting tube and the chassis.

[0053] Furthermore, it also includes a supporting component, which includes a sleeve plate, on which a rotating shaft matching the shaft hole is arranged, and the arc radius of the arc-shaped friction surface 320 is equal to the radius of the rotating shaft. Specifically, by setting the radius of the friction surface to be consistent with the radius of the rotating shaft, the friction surface can better fit with the outer peripheral surface of the rotating shaft when in contact, thereby ensuring the friction effect, wherein the extrusion column and the extrusion part can be integrally formed of steel, an arc groove is arranged on the extrusion part, and a rubber layer (not shown in the figure) is arranged in the arc groove, wherein the friction surface 320 is the surface of the rubber layer, and the rubber layer can ensure a good friction effect on the one hand, and protect the outer peripheral surface of the rotating shaft on the other hand.

[0054] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
