[0006] By adopting the above technical solutions: the whistle can be blown to call for help in an emergency, the north pointer can be used to find the direction, and the straight edge and the protractor can be used in cooperation to measure the azimuth of the position. The present application integrates various functional parts together, which is convenient to carry.

[0007] A shell seat for accommodating the north pointer is fixedly arranged on the base plate, the circumferential side of the shell seat is provided with an annular protruding rib, and a groove for embedding the protruding rib is formed in the inner wall of the sleeve, so that the sleeve is rotatably installed on the shell seat.

[0008] By adopting the above technical solutions: the north pointer is installed through the connection of the sleeve and the shell seat, the sleeve and the shell seat are connected through the protruding rib and the groove, so that the sleeve, the north pointer and the shell seat are combined together, which is convenient to use and also facilitates the rotation of the sleeve, and ensures that the protractor on the sleeve can be normally used.

[0009] An arrow is arranged on the whistle body, the arrow coincides with any normal line of the protractor, and the arrow is parallel to the straight edge.

[0010] By adopting the technical scheme, the arrow is arranged parallel to the straight edge, so that the reading on the scale circle can be read through one end of the arrow.

[0011] The straight edge is provided with a scale line, and the scale line has a ratio of 1:50000.

[0012] By adopting the technical scheme, the distance on the map can be measured by using the scale line, and the actual distance can be converted by the ratio of 1:50000.

[0013] The front end of the whistle body is provided with a plug.

[0014] By adopting the technical scheme, the plug can adjust the air inlet speed of the whistle and play a role in adjusting the frequency.

[0022] The utility model is described in detail below in combination with the drawings. Figures 1-3 The utility model is described in detail below in combination with the drawings.

[0023] The embodiment provides an outdoor whistle for calling for help with the directional function, as shown in Figure 1 and Figure 3As shown, it includes the base plate 1, the base plate 1 is installed with the whistle body 2 and the compass 3, the top end of the compass 3 is rotatably connected with the sleeve 4, the top end of the sleeve 4 is provided with the scale circle 41, the scale circle 41 has an angle value of 0-360°, the two sides of the base plate 1 are provided as parallel straight edges, the front end of the whistle body 2 is provided with the plug 6, the end of the whistle body 2 is close to the sleeve 4, the plug 6 can adjust the air intake speed of the whistle, and plays a role in adjusting the frequency. In an emergency, the whistle can be blown to call for help, the compass 3 can also be used to find the direction, and the straight edge and the scale circle 41 can be used together to measure the azimuth of the position, providing a variety of lifesaving means for outdoor enthusiasts, meeting the outdoor needs, and the scheme integrates various functional parts together, facilitating carrying.

[0024] In order to install the compass 3, as shown, Figure 2 The base plate 1 is fixedly provided with a shell seat 5 for accommodating the compass 3, the circumferential side of the shell seat 5 is provided with an annular protruding rib 51, and the inner wall of the sleeve 4 is provided with a groove 42 for embedding the protruding rib 51, so that the sleeve 4 is rotatably installed on the shell seat 5. Therefore, the compass 3 is installed through the connection of the sleeve 4 and the shell seat 5, and the sleeve 4 and the shell seat 5 are connected through the protruding rib 51 and the groove 42, so that the sleeve 4, the compass 3 and the shell seat 5 are combined together, facilitating carrying and use, and also facilitating the rotation of the sleeve 4, ensuring that the scale circle 41 on the sleeve 4 can be normally used.

[0025] Since the direction of the compass 3 is magnetic north, there will be an azimuth angle (magnetic declination angle), that is, the included angle between the magnetic meridian and the geographic meridian, and by measuring the azimuth angle, it is easier for outdoor enthusiasts to understand their geographic position.
