Detailed Description

The present application is described in further detail below with reference to figures 1-8.

Example 1

The embodiment of the application discloses sputum aspirator with pull rod. Referring to fig. 1, a sputum aspirator with a pull rod 3 comprises a sputum aspirator body 1, wherein the sputum aspirator body 1 comprises a shell 2, a pulley 4 arranged at the lower end of the shell 2 and the pull rod 3 arranged on one side of the shell 2. Four pulleys 4 are provided and rotatably connected to the housing 2. The pull rod 3 is used for conveniently pushing and pulling the sputum aspirator.

In particular, with reference to fig. 1 and 2, the tie rod 3 comprises two first connecting rods 5 and one second connecting rod 6. The two first connecting rods 5 are perpendicular to the second connecting rod 6 and located at two ends of the second connecting rod 6 respectively. The first connecting rod 5 has one end mounted to the housing 2 and the other end mounted to the second connecting rod 6, thereby forming an Contraband type for facilitating the force application of the nurse. The nurse's accessible is to the application of force of second connecting rod 6 to realize pushing or pulling to the sputum aspirator under the biography power of first connecting rod 5.

In order to adapt the pull rod 3 to nurses of different heights, the first connecting rod 5 is adjustable in length, see fig. 1 and 2. Specifically, the first connecting rod 5 includes a fixing portion 7 and an adjusting portion 8. The fixing portion 7 is fixedly connected to one side of the outer wall of the housing 2. The adjusting part 8 is screwed outside the fixing part 7. The second connecting rod 6 comprises two mutually rotatable connecting parts 20, one connecting part 20 corresponding to each adjusting part 8. The end of the adjusting part 8, which is far away from the fixing part 7, is rotatably connected to the connecting part 20 through a bearing. The length of the first connecting rod 5, and thus the draw rod 3, can be adjusted by screwing the adjustment portion 8 in turn. The pull rod 3 is suitable for different people, so that a nurse does not need to bend down when pushing and pulling the sputum aspirator, and pregnant women can push and pull the sputum aspirator through the pull rod 3.

To facilitate reducing the space occupied by the drawbar 3 during storage, referring to fig. 1 and 2, the drawbar 3 is pivotally connected to the housing 2. When the sputum suction apparatus is pushed through the pull rod 3, the pull rod 3 can be rotated relative to the shell 2, so that the pull rod 3 is in an inclined state, and the force is applied to the sputum suction apparatus conveniently. When the sputum aspirator is not needed to be pushed, the pull rod 3 can be rotated to ensure that the pull rod 3 is abutted against one end of the shell 2, so that the space occupied by the pull rod 3 is reduced, and the sputum aspirator is convenient to place.

Specifically, referring to fig. 1 and 2, two mounting seats 9 are fixedly mounted on the housing 2, and one mounting seat 9 corresponds to one fixing portion 7. Referring to fig. 3, the mounting seat 9 is provided with a receiving groove 10, and the fixing portion 7 is located in the receiving groove 10 and abuts against an inner wall of the receiving groove 10. An adjusting bolt 11 penetrates through the mounting seat 9, the adjusting bolt 11 penetrates through the mounting seat 9 and the fixing portion 7, and one end of the adjusting bolt 11 is in threaded connection with an adjusting nut 12. The pressure of the adjusting nut 12 against the side wall of the mounting seat 9 can be adjusted by screwing the adjusting nut 12, so that the resistance force which needs to be overcome when the pull rod 3 rotates relative to the shell 2 is adjusted, the pull rod 3 can rotate relative to the shell 2, and meanwhile, the angle after artificial rotation can be maintained relative to the shell 2.

The implementation principle of this application embodiment 1 a sputum aspirator with pull rod 3 does:

the length of the first connecting rod 5 is adjusted to be suitable according to the height of a user by rotating the adjusting part 8. When needs promote the sputum aspirator, rotate pull rod 3, make pull rod 3 wholly be the slope setting, then through pull rod 3 to inhale the sputum aspirator application of force, make the removal that the sputum aspirator can be smooth and easy. When the sputum aspirator is not required to be pushed, the pull rod 3 is rotated, so that the pull rod 3 is attached to one side of the outer wall of the shell 2, and the occupied space is reduced.

Example 2

Embodiment 2 differs from embodiment 1 in that, referring to fig. 4 and 5, the fixing portion 7 and the adjusting portion 8 are connected in different manners. The adjusting part 8 is sleeved outside the fixing part 7. Annular groove 13 has been seted up to the 8 inner walls of regulating part, and annular groove 13 has seted up a plurality of along the 8 axial of regulating part. The ring groove 13 is circular arc-shaped. The inner wall of the adjusting part 8 is provided with a communicating groove 14 along the axial direction of the adjusting part 8, and the communicating groove 14 is communicated with all the ring grooves 13. Two connecting grooves are arranged along the circumferential direction of the ring groove 13. Referring to fig. 5 and 6, the outer wall of the fixing portion 7 is fixedly provided with two mounting blocks 15 embedded in the ring groove 13, and each mounting block 15 is provided with one communicating groove 14 corresponding to one mounting block 15.

When the length of the pull rod 3 needs to be adjusted, the adjusting part 8 is rotated relative to the fixing part 7, the mounting block 15 is aligned with the communication groove 14, and then the adjusting part 8 slides relative to the fixing part 7 until the length of the pull rod 3 is adjusted to a proper range. The adjustment portion 8 is then rotated by the noble fixing portion 7 so that the mounting block 15 slides into the corresponding ring groove 13.

Example 3

Embodiment 3 differs from embodiment 1 in that, referring to fig. 7 and 8, the fixing portion 7 and the adjusting portion 8 are connected in different manners, and the second connecting rod 6 is different. The outer wall of the fixing part 7 is provided with two spring jumping beans 16, and the number of the spring jumping beans 16 is two along the axial direction of the fixing part 7. The adjusting holes 17 are provided in a plurality along the axial direction of the adjusting portion 8. At least one spring bean 16 is embedded in the adjusting hole 17. The adjusting part 8 can slide relative to the fixing part 7 by applying force to the second connecting rod 6, so that the spring jumping beans 16 are embedded in different adjusting holes 17, and the length of the first connecting rod 5 is adjusted.

In order to prevent the adjusting part 8 from sliding excessively relative to the fixing part 7, the outer wall of the fixing part 7 is provided with a limiting groove 18 along the axial direction, and the inner wall of the adjusting part 8 is fixedly provided with a limiting block 19. The limiting block 19 is slidably connected in the limiting groove 18. The limiting groove 18 is matched with the limiting block 19, so that the adjusting part 8 cannot completely leave the fixing part 7, and the adjusting part 8 is prevented from excessively sliding relative to the fixing part 7.

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.
