Description

Portable geographic information surveying instrument

Technical Field

The utility model relates to a mapping device, more precisely, be a portable geographic information surveying instrument.

Background

When the geographic information surveying instrument is used, the geographic information surveying instrument is usually directly fixed on a tripod, and the inclination angle of the surveying instrument is difficult to adjust, so that the surveying and mapping are influenced.

SUMMERY OF THE UTILITY MODEL

The utility model discloses solve the technical problem that prior art exists to a portable geographic information surveying instrument is provided.

The above technical problem of the present invention can be solved by the following technical solutions:

a portable geographic information surveying instrument is characterized by comprising a fixed base, wherein a rotatable positioning ball seat is arranged on the fixed base, a detachable positioning ball rod is arranged on the positioning ball seat, the fixed base comprises a disc-shaped base disc and a rod-shaped base shaft rod, a conical positioning groove and an annular locking ring groove are arranged at the top of the base shaft rod, a positioning round hole is arranged on the side wall of the positioning ball seat, a locking screw head penetrates through the positioning round hole and tightly abuts against the locking ring groove, the positioning ball rod comprises a rod-shaped ball rod main body, a spherical positioning ball head is arranged at the tail of the ball rod main body, a locking disc head is arranged on the ball rod main body, and a detachable elastic damping cap is arranged in the positioning groove, the damping cap is matched with the positioning ball head and comprises a cylindrical cap body and a conical cap cone.

As the preferred embodiment of the utility model, the damping cap is made of silica gel.

The utility model discloses a portable geographic information surveying instrument has following advantage: during the use, the user can be with surveying instrument direct mount to the club main part of location club to it is fixed with the surveying instrument to utilize the locking coiled hair. When the user need adjust the angle that sets up of surveying instrument, as long as not hard up locking spiral shell head, the user just can freely adjust the position of location bulb in positioning groove, then, screws the locking spiral shell head once more, can be fixed with the surveying instrument. Because the damping cap that a silica gel was made is equipped with in the positioning groove, can effectively prevent location bulb and shake and unexpected slippage, improved the survey and drawing precision of surveying instrument greatly. This portable geographic information surveying instrument simple structure, low cost, the effect is obvious, and the practicality is strong.

Drawings

wherein,

1. a portable geographic information mapper; 2. a fixed base; 21. a base chassis; 22. a base shaft lever; 23. a positioning groove; 24. a locking ring groove; 3. positioning a ball seat; 31. positioning the circular hole; 4. positioning a ball rod; 41. a cue body; 42. positioning a ball head; 5. locking the disc head; 6. a damping cap; 61. a cap body; 62. a cap cone; 7. and locking the screw head.

Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.

As shown in fig. 1 to 6, the portable geographic information surveying instrument 1 includes a fixed base 2, a rotatable positioning ball seat 3 is disposed on the fixed base 2, a detachable positioning ball rod 4 is disposed on the positioning ball seat 3, the fixed base 2 includes a disc-shaped base plate 21 and a rod-shaped base shaft rod 22, a conical positioning groove 23 and an annular locking ring groove 24 are disposed on the top of the base shaft rod 22, a positioning circular hole 31 is disposed on the sidewall of the positioning ball seat 3, a locking screw head 7 penetrates through the positioning circular hole 31 and tightly abuts against the locking ring groove 24, the positioning ball rod 4 includes a rod-shaped ball rod main body 41, a spherical positioning ball head 42 is disposed on the tail of the ball rod main body 41, a locking plate head 5 is disposed on the ball rod main body 41, a detachable elastic damping cap 6 is disposed in the positioning groove 23, the damping cap 6 is matched with the positioning ball head 42, the damping cap 6 comprises a cylindrical cap body 61 and a conical cap cone 62.

The damping cap 6 is made of silica gel.

In use, as shown in figures 1 and 2, a user may mount the mapper directly onto the club body 41 where the club 4 is located and secure the mapper with the locking disc 5. When the user need adjust the angle that sets up of surveying instrument, as long as not hard up locking spiral shell head 7, the user just can freely adjust the position of location bulb 42 in positioning groove 23, then, screws locking spiral shell head 7 once more, can be fixed with the surveying instrument. Because the damping cap 6 made of silica gel is arranged in the positioning groove 23, the positioning ball head 42 can be effectively prevented from shaking and accidentally slipping, and the surveying and mapping precision of the surveying and mapping instrument is greatly improved.

This portable geographic information surveying instrument simple structure, low cost, the effect is obvious, and the practicality is strong.

Without being limited thereto, any changes or substitutions which are not thought of through creative efforts should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
