In this manner, the connection of first connector assembly 220 to mapping device 210 may be made more secure.

In some embodiments, fig. 5 shows a schematic view of a connection of a first connector assembly, fig. 6 shows a cross-sectional view of a first connector assembly, and fig. 6 is a cross-sectional view taken along a-a in a top view of the first connector assembly shown in fig. 7. As shown in fig. 5 and 6, the first connector assembly 220 may further include:

the connector body 222 may be provided with a second groove, and the second groove of the connector body 222 may be provided with a C-shaped clamp spring 223 therein.

The second groove is a groove arranged on the connector body 222 and used for preventing the C-shaped clamp spring 224, and the size of the groove is matched with that of the C-shaped clamp spring 224. The third groove is a groove disposed inside the nut 225 and can be used for placing the connector body 222, and the size of the groove can be matched with the size of the connector body 222.

As an example, the first connector assembly 220 may be mainly composed of three parts, a connector body 222, a C-shaped circlip 223 and a nut 224, wherein the nut 224 may be a profiled nut. In assembling the first connector assembly 220, the C-shaped clamp spring 223 may be first placed in the second groove of the connector body 222. Then, the C-shaped circlip 223 is compressed so that the diameter of the C-shaped circlip 223 is smaller than the inner diameter of the nut 224, and then the C-shaped circlip 223 and the connector body 222 are pushed into the nut 224. When the C-shaped latch spring 223 enters the third groove formed in the nut 224, the C-shaped latch spring 223 is tensioned to latch into the third groove of the nut 224, so as to connect the connector body 222 and the special-shaped nut 224 together.

In a further embodiment, the first connector assembly 220 and the second connector assembly 240 may be movably connected, such as by being threaded, such as by the inner wall of the nut 224 being configured with internal threads that mate with the second connector assembly 240. In this way, the nut 224 is free to rotate relative to the connector body 222, and the mounting of the mapping apparatus 210 to a support 230, such as a fixation rod, is achieved.

In some embodiments, referring to any of fig. 2-4, a knob cover 250 may be disposed outside of the first connector assembly 220. At this time, the connection relationship of the surveying equipment, the connecting device and the supporting member may be as shown in fig. 8.

As an example, as shown in FIG. 8, the top is the mapping apparatus 210, the middle is the connecting device provided with the knob cover 250, and the bottom is the support 230. The knob cover 250 may be secured to the mapping device 210 and may be rotationally movable. Like this, not only remove external pencil, the operation is more convenient, and moreover, the setting of knob lid can make connecting device whole and surveying and mapping equipment 210 can combine together, makes the outward appearance succinct more, novel pleasing to the eye.

In a further embodiment, the knob cover 250 may be a movable member capable of rotating, and the knob cover 250 is fixed in the Z-axis direction and rotatable in the X-axis and Y-axis directions, as may be shown in fig. 9, in a counter-clockwise direction. Wherein, as shown in fig. 9, the Z-axis direction may be a direction perpendicular to the bottom plane of the surveying device 210, i.e. a direction of a dotted line B-B in fig. 9, and the X-axis and the Y-axis are located on the bottom plane of the surveying device, i.e. a plane perpendicular to the Z-axis.

Fig. 10 is a sectional view taken along the broken line C-C in an assembled top view of the knob cover and the first connector assembly 220 shown in fig. 11. As shown in fig. 10, a hook 251 and a fourth groove may be provided in the knob cover 250, the fourth groove in the knob cover matches with the nut 224, and the knob cover 250 may fix the nut 224 in the fourth groove in the knob cover 250 by the hook 251. Thus, the first connector assembly 220 is connected to the second connector assembly 240 by twisting the knob cover 250.

The fourth groove may be a groove disposed on the knob cover for accommodating the nut 224, and the size of the groove matches with the nut 224. The two sides of the hook 251 of the knob cover 250 may be provided with U-shaped slots, and the hook 251 may have good elasticity.

As an example, fig. 12 and 13 show schematic views of a knob cover, a first connector assembly, respectively. The knob cover 250 shown in fig. 12 is assembled with the first connector assembly 220 shown in fig. 13 and can be assembled and fixed mainly by the shape of the hook 251 and the nut 224. Specifically, during assembly, the hook 251 and the fourth groove of the knob cover 250 may be pushed upward in alignment with the nut 224 of the first connector assembly 220. When the nut 224 of the first connector assembly 220 enters the fourth groove of the knob cover 250, the head of the hook 251 of the knob cover 250 is pushed outward by the nut 224 of the first connector assembly 220. At this time, since the two sides of the hook 251 of the knob cover 250 have the U-shaped slots, and the hook 251 has good elasticity, the knob cover 250 continues to be pushed upward, when the hook 251 of the knob cover 250 enters the step surface at the bottom end of the nut 224 of the first connector component 220, the hook 251 of the knob cover 250 is fastened with the nut 224 of the first connector component 220 in the Z-axis direction, and in the horizontal direction, the shape of the fourth slot of the knob cover 250 is matched with the shape of the nut 224 to realize the position limitation in the X-axis and Y-axis directions. Specifically, as shown in fig. 10 and 14, wherein fig. 14 is a partially enlarged view of C in fig. 10, a front view and a sectional view of the knob cover 250 assembled with the first connector assembly 220 may be as shown in fig. 15 and 16, and fig. 16 is a sectional view taken along a dotted line D-D in fig. 15.

When installed, the screw head of the support 230 may be turned to the nut 224 in the cap 250. Then, the knob cover 250 is screwed counterclockwise. During rotation of knob cover 250, second connector assembly 220 may enter nut 224 from the head of the screw (i.e., the external threads) and, by the time knob cover 250 is not screwed, mapping apparatus 210 may be assembled with support 230.

In this manner, first connector assembly 220 may be coupled to a support member via control knob cover 250 to provide support to the overall mapping apparatus 110. So, the nut 224 of the first connector component 220 is a rotatable moving part, and the holding size of the nut 224 is enlarged through the knob cover 250, so that the structure is simple, the installation is more convenient, the reliability is good, better operation experience can be provided, and the threaded connection operation is more in line with the ergonomic design. Meanwhile, the knob cover 250 may cover the nut 224, serving to optimize the appearance.
