DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0037] like Figure 1-5 As shown, a downhole direction indicator includes

[0038] The mounting plate 10 is fixedly connected to the top of the tunnel;

[0039] The positioning cover 30 is detachably fixedly connected to the mounting plate 10;

[0040] The bottom of the projector body 40 extends into the positioning cover 30;

[0041] The positioning plate 41 is fixedly connected to the bottom of the housing of the projector body 40 and extends into the positioning cover 30;

[0042] A plurality of positioning components 50 for clamping the positioning plate 41 in the positioning cover 30;

[0043] The positioning assembly 50 includes an insert rod 53 movably disposed on the positioning cover 30 , and the insert rod 53 is used to clamp the positioning plate 41 ;

[0044] A driving assembly 60 is provided on the outer wall of the positioning cover 30 and is used to drive the insertion rod 53 to move;

[0045] The rotating ring 80 is fixedly mounted on the outer circumferential wall of the housing of the projector body 40 and has a plurality of through holes 81;

[0046] A grip rod 92 has a plurality of push rods 90 arranged in a ring at one end, and the push rods 90 pass through the through holes 81 at corresponding positions and provide power to the drive assembly 60;

[0047] A plurality of limiting sleeves 91 are respectively fixedly connected to the handle bar 92 and sleeved on the outer periphery of the push rod 90 .

[0048] This embodiment is implemented as follows:

[0049] When the indication direction needs to be adjusted, hold the grip 92 and pass the push rod 90 through the through hole 81 so that the push rod 90 can provide thrust to the drive assembly 60. During this process, the elastic limit sleeve 91 will be gradually compressed, and the insertion rod 53 will be moved by the drive assembly 60, so that the insertion rod 53 releases the positioning plate 41. Then the worker rotates the grip 92 to make the push rod 90 drive the rotating ring 80 to rotate, and the rotating ring 80 drives the projector body 40 and the positioning plate 41 to rotate until the arrow projected by the projector body 40 reaches the required angle and stops. Then move the grip 92 downward. During the downward movement, the limit sleeve 91 will gradually return to its original shape. During this process, the limit sleeve 91 will drag the rotating ring 80 to prevent the projector body 40 from moving downward. At this time, the insertion rod 53 will clamp the limit groove 51 again to position the positioning plate 41.

[0050] The advantages of the present application over the prior art are that it can be installed on the top of a tunnel and the direction of the arrow can be adjusted.

[0051] See also Figure 1 、 2 3. The positioning assembly 50 further includes a first spring 54 slidably mounted on the insertion rod 53. One end of the first spring 54 is fixedly connected to the insertion rod 53, and the other end is fixedly connected to the positioning cover 30. The insertion rod 53 slides through the sliding hole 52 on the side wall of the positioning cover 30. The outer circumferential wall of the positioning plate 41 has a plurality of annularly arranged limiting grooves 51 at positions corresponding to the insertion rod 53.

[0052] The present application can position the insertion rod 53 through the first spring 54, so that the insertion rod 53 is inserted into the limiting groove 51 of the positioning plate 41, thereby fixing the positioning plate 41. When the insertion rod 53 is pulled out of the limiting groove 51, the first spring 54 is stretched. When the driving component 50 releases the insertion rod 53, the insertion rod 53 will be driven to enter the corresponding position limiting groove 51 again under the action of the first spring 54.

[0053] See also Figure 1 、 2 , 3, 4, 5, the drive assembly 60 includes

[0054] A positioning ring 61 is fixedly mounted on the outer wall of the positioning cover 30 and has a movable hole 62 at a position corresponding to the insertion rod 53;

[0055] A plurality of movable rods 63 are respectively slidably passed through the movable holes 62;

[0059] A plurality of connecting ropes 66 are respectively passed through the plurality of connecting ropes 66 , one end of the connecting rope 66 is fixedly connected to the moving rod 63 , and the other end is fixedly connected to the insertion rod 53 ;

[0060] After the link 70 is pushed by the push rod 90, the link 70 drives the moving rod 63 to move. At this time, the second spring 64 is stretched, and the movement of the moving rod 63 pulls the connecting rope 66, so that the connecting rope 66 pulls the insertion rod 53 to move.

[0061] When the link 70 is not pushed by the push rod 90 , the restoring force of the second spring 64 drives the moving rod 63 back to its original position, thereby driving the connecting rope 66 back to its original position.

[0062] See also Figure 1 、 2 3. The mounting plate 10 is provided with a connecting column 20, which is fixed to the top of the tunnel;

[0063] By fixing the connecting pillars 20 in the tunnel roof by cement, the mounting plate 10 can be fixed.
