Specific embodiments

[0021] The following further describes the specific embodiments of the present utility model with reference to the accompanying drawings.

[0022] As Figure 1-7 shown, a slope measuring device includes a cavity 1 with an open lower end. The upper end of the cavity 1 has a semi-circular surface. A scale 2 is provided on the semi-circular surface at the upper end of the cavity 1. A protrusion 3 is provided on the outer surface of the cavity 1. A pointer 4 is rotatably connected to the outer surface of the protrusion 3. The pointer 4 has an indicating end and a counterweight end. The counterweight end of the pointer 4 always faces the ground under the action of its own gravity. The indicating end of the pointer 4 is located on one side of the scale 2. The device further includes a friction device for restricting the rotation of the pointer 4, a positioning device for continuously restricting the rotation of the pointer 4 by the friction device, and a reset device for releasing the restriction of the positioning device on the friction device.

[0023] When the lower end of the cavity 1 is placed on a horizontal ground, the counterweight end of the pointer 4 is perpendicular to the lower end surface of the cavity 1. At this time, the reading of the scale 2 pointed to by the indicating end of the pointer 4 is 0°. When the lower end of the cavity 1 is placed on a wall perpendicular to the ground, the counterweight end of the pointer 4 is still perpendicular to the ground. At this time, the reading of the scale 2 pointed to by the indicating end of the pointer 4 is 90°. Whether the pointer 4 rotates clockwise or counterclockwise, it can indicate from 0° to 90°.

[0024] Furthermore, the friction device includes guide rods 5 symmetrically arranged inside the cavity 1. A guide frame 6 is slidably connected to the guide rods 5. One end of the guide frame 6 is provided with a push rod 7. One end of the push rod 7 sequentially penetrates through the cavity 1 and the protrusion 3 and is fixedly connected to the positioning plate 8. A first spring 9 is sleeved on the guide rod 5. The first spring 9 is used to push the guide frame 6 towards the direction close to the pointer 4. A flange 10 is provided inwardly at the lower end of the cavity 1. A contact part is slidably connected inside the lower end of the cavity 1. The contact part includes an intermediate block 11 slidably connected to the flange 10. A bottom plate 12 is provided at the lower end of the intermediate block 11. A top plate 13 is provided at the upper end of the intermediate block 11. A push rod 14 is provided on the upper surface of the top plate 13. The upper end of the push rod 14 is provided with an inclined surface. The push rod 14 is used to push the guide frame 6 away from the pointer 4 through the inclined surface. A side plate 15 is provided inside the cavity 1. An elastic block 16 is provided between the side plate 15 and the top plate 13. When it is necessary to restrict the rotation of the pointer 4, first place the bottom plate 12 of the device on the slope whose gradient needs to be measured. When the bottom plate 12 is completely attached to the slope, the reading on the scale 2 indicated by the indicating end of the pointer 4 at this time is the gradient. Then control the cavity 1 and squeeze it downward. When squeezing the cavity 1 downward, the distance between the bottom plate 12 and the cavity 1 is shortened. At this time, the push rod 14 moves upward in the cavity 1. When the push rod 14 moves upward, it enters the guide frame 6 through the inclined surface at the upper end of the push rod 14 and pushes the guide frame 6 to move through the inclined surface. The guide frame 6 moves away from the pointer 4. When the guide frame 6 moves, it drives the push rod 7 to move. The push rod 7 drives the positioning plate 8 to move. When the positioning plate 8 contacts the outer surface of the pointer 4, due to the frictional force between the positioning plate 8 and the pointer 4, the rotation of the pointer 4 can be avoided.

[0025] Further, the positioning device includes an abutting block 17 with inclined surfaces on both sides. A sliding groove for the sliding of the abutting block 17 is provided inside the top plate 13. A second spring 18 is provided between the abutting block 17 and the bottom of the sliding groove. A sliding rod 19 is provided inside the top plate 13. A through groove is formed inside the top plate 13. Side rods 20 are symmetrically arranged on the sliding rod 19. The side rods 20 are located inside the through groove. A third spring 21 is provided inside the through groove. The third spring 21 is used to push the sliding rod 19 towards the direction close to the abutting block 17. A positioning hole 22 matching with the sliding rod 19 is provided on the outer surface of the cavity 1. When the pointer 4 cannot rotate by its own gravity under the frictional force of the positioning plate 8, in order to facilitate taking away the cavity 1 from the slope, it is necessary to keep the positioning plate 8 in continuous contact with the pointer 4. Specifically, when the top plate 13 moves upward inside the cavity 1, it will drive the sliding rod 19 to move upward. When the sliding rod 19 moves to the positioning hole 22, under the action of the second spring 18, the abutting block 17 is pushed to move. When the abutting block 17 moves, it pushes the sliding rod 19 to move inside the through groove. At this time, the third spring 21 is in a further compressed state. When one end of the sliding rod 19 enters the positioning hole 22, the position positioning of the top plate 13 is completed. At this time, the position of the top plate 13 will not change, that is, the position of the push rod 14 will not change. The positioning plate 8 can continuously maintain a large frictional force with the pointer 4, which can prevent the pointer 4 from rotating under the action of its own gravity. At this time, after taking away the device from the slope, the position of the pointer 4 will not change, which is convenient for the user to read the slope.

[0026] Further, the reset device includes an extrusion block 23. An installation groove for the sliding connection of the extrusion block 23 is formed on the outer surface of the cavity 1. Side plates 24 are symmetrically arranged on the outer surface of the extrusion block 23. It also includes a fourth spring 25 arranged inside the installation groove. The fourth spring 25 pushes the extrusion block 23 towards the outside of the cavity 1 through the side plates 24. When the pointer 4 needs to be reset, only by pressing the extrusion block 23. After pressing the extrusion block 23, the fourth spring 25 is in a further compressed state. At the same time, one end of the extrusion block 23 contacts one end of the abutting block 17 and pushes the abutting block 17 to move inside the sliding groove, so that the second spring 18 inside the sliding groove is compressed. Under the action of the third spring 21, the sliding rod 19 is pushed towards the direction of the abutting block 17 through the side rod 20. At this time, one end of the sliding rod 19 withdraws from the positioning hole 22. Under the condition of the self-gravity of the elastic block 16 and the top plate 13, etc., the top plate 13 moves towards the lower end of the cavity 1 and drives the push rod 14 away from the guiding frame 6. At the same time, the guiding frame 6 moves towards the direction close to the pointer 4 and drives the positioning plate 8 away from the pointer 4. At this time, the pointer 4 can rotate freely and can continue to measure the slope of the ramp.

[0027] Further, handles 26 are symmetrically arranged on the outer surface of the cavity 1. It is convenient to control the cavity 1 through the handles 26.

[0028] Further, it further includes a transparent housing 27 provided on the outer surface of the cavity 1. The pointer 4 and the scale 2 are both located inside the housing 27, and the housing 27 facilitates protecting the pointer 4 for normal use.

[0029] Further, a rotatable rotating shaft 28 is provided inside the guiding frame 6. By providing the rotating shaft 28, the friction between the upper end of the push rod 14 and the guiding frame 6 can be reduced, making the movement of the guiding frame 6 smoother.

[0030] When the device is in use, it can fix the position of the pointer 4 after rotation, so that the pointer 4 can continuously indicate the measured slope reading. After the staff places the device on the slope and fixes the pointer 4, the device can be directly picked up, and the staff can read the slope without getting close to the ramp, improving the convenience of use.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components.
