[0031] Example 1:

[0032] like Figures 1 to 4As shown, the rotary cutting sampling device for ointment sampling provided in this embodiment includes: a shell 1 with a cylindrical groove inside, the cylindrical groove penetrating the bottom of the shell 1, and a scale line marked on one side of the outer shell 1; a cylindrical shaft 2, which is slidably connected to the top middle of the shell 1; and an L-shaped plate 3, which is L-shaped, placed upside down, with one end of the L-shaped plate 3 fixed to the cylindrical shaft 2, and a sliding cover 4 provided at the bottom of the other end.

[0033] In this embodiment, the sliding cover 4 constitutes a rotary cutting sampling device for ointment sampling according to this application.

[0034] It should also be noted that the rotary cutting sampling device for ointment sampling in this application can be a manually driven rotary cutting sampling device, an electrically driven rotary cutting sampling device, a pneumatically driven rotary cutting sampling device, etc. Figure 1 In this embodiment, a manually driven rotary cutting sampling device for ointment sampling is used as an example for description. Of course, other types of rotary cutting sampling devices for ointment sampling can also adopt similar structures, which will not be described in detail below.

[0035] Understandable, Figure 1 This illustration only schematically shows some components of a rotary cutting sampling device for ointment sampling. The actual shape, size, position, and construction of these components are not subject to change. Figure 1 Due to limitations, a rotary cutting sampling device for ointment sampling can also include, compared to... Figure 1 More or fewer parts.

[0036] In this embodiment, the outer shell 1 is made of 304 stainless steel and has a single cylindrical groove inside, which vertically penetrates the bottom of the outer shell 1. Millimeter-level graduations are marked on one side of the outer shell 1 along its height. The cylindrical shaft 2 is a solid cylindrical structure, one in number, and is vertically slidably connected to the center of the top of the outer shell 1. The L-shaped plate 3 is made of metal, with an L-shaped right-angle structure, and is placed upside down. One end of the L-shaped plate 3 is vertically fixed to the top of the cylindrical shaft 2, and the other end has a horizontally positioned sliding cover 4 at its bottom. The outer shell 1 provides a sampling chamber, and the cylindrical shaft 2 can move the L-shaped plate 3 up and down, with the sliding cover 4 moving synchronously with the L-shaped plate 3. This establishes the basic structure of the device, providing support for subsequent sampling volume control and operation.

[0037] Specifically, a spring 21 is sleeved on the outside of the cylindrical shaft 2. The top end of the spring 21 is fixed to the bottom of one end of the L-shaped plate 3, and the bottom end is fixed to the top of the outer shell 1.

[0038] In this embodiment, a spring 21 is coaxially sleeved on the outside of the cylindrical shaft 2. Spring 21 is a cylindrical helical compression spring, one in number, made of spring steel. The top end of spring 21 is fixed to the lower surface of one end of the L-shaped plate 3, and the bottom end is fixed to the upper surface of the outer casing 1. When the L-shaped plate 3 is pressed, spring 21 is compressed and contracts; when the L-shaped plate 3 is released, spring 21 elastically rebounds, causing the L-shaped plate 3 and the cylindrical shaft 2 to return to their original positions. This achieves automatic reset of the cylindrical shaft 2 and the L-shaped plate 3, reducing manual operation steps.

[0039] Specifically, a push plate 22 is fixed at the bottom of the cylindrical shaft 2. The push plate 22 is made of polytetrafluoroethylene and is connected to the piston of the outer shell 1.

[0040] In a preferred embodiment, a push plate 22 is fixed at the center of the bottom end face of the cylindrical shaft 2. The push plate 22 is a circular flat plate made of 304 stainless steel, and its diameter is the same as the inner diameter of the cylindrical groove inside the outer shell 1. The push plate 22 can slide along the axial direction of the cylindrical groove inside the outer shell 1. When the cylindrical shaft 2 moves up and down, it drives the push plate 22 to slide synchronously in the cylindrical groove; the downward movement of the push plate 22 can squeeze the paste in the groove, and the upward movement can push the paste out. This realizes the unloading operation after the paste is sampled, avoiding paste residue in the groove.

[0041] Example 2:

[0042] Based on Embodiment 1, in order to facilitate the fixing of the push plate 22, several sets of limiting grooves 100 are evenly and vertically opened on the outer side of the outer shell 1.

[0043] Specifically, several sets of limiting grooves 100 are evenly and vertically opened on the side of the outer shell 1 near the scale line.

[0044] In this embodiment, a plurality of limiting grooves 100 are uniformly and vertically formed along the height direction on the outer surface of the outer shell 1 near the scale line. The limiting grooves 100 are rectangular grooves. One end of the sliding cover 4 can be embedded in the limiting groove 100 to restrict the vertical movement of the sliding cover 4 and the L-shaped plate 3, thereby fixing the position of the cylindrical shaft 2 and the push plate 22. This provides a limiting basis for locking the sampling amount and ensures the stability of the sampling amount.

[0045] Specifically, the sliding cover 4 is flush with the cylindrical shaft 2, and one end of the sliding cover 4 is inclined. This end of the sliding cover 4 can slide in the limiting groove 100, and the other end is slidably connected to the rectangular groove on one side of the bottom of the L-shaped plate 3.

[0046] In this configuration, the sliding cover 4 is a rectangular box-shaped structure, and there is only one of them. The end of the sliding cover 4 closest to the outer shell 1 is inclined, and the inclined end of the sliding cover 4 can slide vertically along the limiting groove 100. The other end slides horizontally and is connected to the rectangular groove on one side of the bottom of the L-shaped plate 3. When the L-shaped plate 3 is pressed, the inclined end of the sliding cover 4 is squeezed by the surface of the outer shell 1 and slides outward along the rectangular groove of the L-shaped plate 3, disengaging from the limiting groove 100. After the press is released, the sliding cover 4 returns to its original position and is embedded in the limiting groove 100 at the corresponding height under the action of elasticity. This realizes the automatic switching of the limiting state and, together with the limiting groove 100, completes the locking and unlocking of the sampling volume.

[0047] Example 3:

[0048] Based on embodiment 2, in order to facilitate the adjustment of the height of the push plate 22, a pull rod 41 is provided inside the sliding cover 4;

[0049] Specifically, a pull rod 41 is also provided inside the sliding cover 4. One end of the pull rod 41 is fixed to the inner wall of the sliding cover 4, and the other end is slidably connected to the bottom of the L-shaped plate 3.

[0050] The sliding cover 4 has a horizontally mounted pull rod 41 inside. The pull rod 41 is a solid round rod, with one end vertically fixed to the inner wall of the sliding cover 4 away from the outer shell 1, and the other end horizontally sliding through and connected to the side wall of the rectangular groove at the bottom of the L-shaped plate 3. Pulling the pull rod 41 outwards moves the sliding cover 4 horizontally, disengaging the inclined end from the limiting groove 100; releasing the pull rod 41 resets the sliding cover 4. A manual unlocking limit is provided for easy adjustment of the sampling volume or emergency unloading.

[0051] Specifically, a second spring 42 is fitted on the pull rod 41. One end of the second spring 42 is fixed to one side of the inner wall of the sliding cover 4, and the other end is fixed in the rectangular groove at the bottom of the L-shaped plate 3.

[0052] In this embodiment, a second spring 42 is coaxially sleeved on the pull rod 41. The second spring 42 is a cylindrical helical compression spring made of spring steel. One end of the second spring 42 is fixed to the inner wall of the sliding cover 4 away from the outer shell 1, and the other end is fixed to the side wall of the rectangular groove at the bottom of the L-shaped plate 3. When the pull rod 41 is pulled, the second spring 42 is compressed and contracted; when the pull rod 41 is released, the second spring 42 elastically rebounds and pushes the sliding cover 4 back to its original position, so that its inclined end is embedded in the limiting groove 100. This ensures that the sliding cover 4 stably fits the limiting groove 100 and avoids limiting failure due to vibration during sampling.

[0053] In actual use, the user places the entire device above the ointment, presses down and rotates until the ointment is removed. At this time, the ointment is taken into the cylindrical groove inside the outer shell 1. Then, the cylindrical shaft 2 is pressed down, the spring 21 is compressed, the push plate 22 moves down along the cylindrical groove inside the outer shell 1, and the L-shaped plate 3 on the cylindrical shaft 2 moves down accordingly. At this time, the sliding cover 4 at the bottom of the L-shaped plate 3 slides out of the limiting groove 100 according to its inclined shape design. After the user presses the cylindrical shaft 2 to a suitable height according to the scale line on the outside of the outer shell 1, the sliding cover 4 is re-inserted into the limiting groove 100. This design can control the amount of ointment removed. If adjustment is required, the pull rod 41 can be pulled outward, that is, the spring 42 is compressed and the sliding cover 4 is pulled out. The spring 21 is unloaded and rebounds, pulling the L-shaped plate 3, the sliding cover 4 and the device on it upward. The sliding cover 4 can be re-inserted into the limiting groove 100 on one side of the outer shell 1 as needed.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
