Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses a surveying and mapping sighting rod. Referring to fig. 1, the drilling tool comprises a rod body 1, a drilling bit 2 and a protective sleeve 3, wherein the rod body 1 is cylindrical, and the drilling bit 2 is welded at the bottom of the rod body 1. Protective sleeve 3 slidable mounting is at the periphery wall of the body of rod 1, and protective sleeve 3 can overlap and establish outside drill bit 2. Install mounting 4 on the protective sleeve 3, protective sleeve 3 passes through mounting 4 and locks the periphery wall at the body of rod 1.

Referring to fig. 2, the fixing member 4 includes a plurality of arc-shaped clamping pieces 41 and a nut 42, wherein the thickness of one end of the plurality of arc-shaped clamping pieces 41 away from the protective sleeve 3 is greater than the thickness of one end of the plurality of arc-shaped clamping pieces 41 close to the protective sleeve 3, one end of the plurality of arc-shaped clamping pieces 41 is fixed at one end of the protective sleeve 3, and the plurality of arc-shaped clamping pieces 41 surround to form a pipeline. The outer peripheral wall of the pipeline is provided with an external thread line in threaded connection with the nut 42.

Referring to fig. 4, when the nut 42 is far away from the protection sleeve, the arc-shaped clamping piece 41 is clamped on the rod body 1 under the action of the nut 42, so that the acting force between the arc-shaped clamping piece 41 and the rod body 1 is large, and the protection sleeve 3 is prevented from sliding along the axial direction of the rod body 1. When the surveying and mapping marker post is not needed, the protective sleeve 3 is moved to sleeve the drill bit 2, and the nut 42 is rotated, so that the condition that the drill bit 2 is accidentally injured is avoided.

In order to prevent the nut 42 from being disengaged from the arc-shaped grip piece 41, a first limit projection 43 is welded to a side of the arc-shaped grip piece 41 away from the protective sleeve 3. A second limiting bulge 44 is welded on the outer peripheral wall of the protective sleeve 3 and at a position close to the arc-shaped clamping piece 41. The nut 42 is prevented from being disengaged from the arc-shaped clamping piece 41 by the restriction of the first and

second stopper protrusions

43 and 44.

Referring to fig. 2, a protective cover 45 is installed at one end of the protective sleeve 3 far away from the rod body 1, an inner thread line is arranged in the protective cover 45, and an outer thread line in threaded connection with the protective cover 45 is arranged on the outer peripheral wall of the protective sleeve 3. The protective cap 45 is screw-mounted on the protective sleeve 3.

In order to prevent the protective cover 45 from being lost, the link chain 46 is welded to the protective cover 45, and the other end of the link chain 46 is welded to the outer peripheral wall of the sleeve.

Referring to fig. 3, the guide block 5 is welded on the inner peripheral wall of the protective sleeve 3 and at a position close to the fixing member 4, the outer peripheral wall of the rod body 1 is provided with a guide groove 6 along the axis direction thereof, and the guide block 5 slides in the guide groove 6. Can avoid taking place relative rotation between protective sleeve 3 and the body of rod 1 through guide block 5 and guide way 6, simultaneously, can avoid protective sleeve 3 to break away from the body of rod 1.

The periphery wall cover at guide block 5 is equipped with elastic protection cover, and elastic protection cover is rubber products in this embodiment. Impact force generated when the guide block 5 collides with the rod body 1 is reduced through the elastic protection sleeve, so that damage caused by overlarge stress on the guide block 5 is avoided.

The implementation principle of the surveying and mapping sighting rod of the embodiment of the application is as follows: at the in-process of transportation survey and drawing sighting rod, remove protective sleeve 3 for protective sleeve 3 entangles drill bit 2, then locks protective sleeve 3 on the body of rod 1 through mounting 4, avoids the condition emergence that drill bit 2 stabbed the people in proper order.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
