Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to a connecting limiting mechanism and a liquid extraction device. Background Technology

[0002] Formalin is an aqueous solution of formaldehyde. It is colorless and transparent, corrosive, and binds to the amino groups of proteins, causing them to coagulate. Therefore, it is used in medicine as a tissue fixative and preservative in laboratory tests, and is widely used in operating rooms for fixing surgical specimens. Because the formaldehyde it contains is highly volatile, it immediately emits a strong, irritating odor upon opening, and is highly irritating to the skin, eyes, mouth, nose, and respiratory mucous membranes. Furthermore, numerous scientific studies and animal experiments have long indicated that long-term exposure to formalin may lead to cancer. Therefore, when using formalin solution for surgical specimen fixation, a solution pump should be used to significantly reduce occupational exposure and ensure safe liquid extraction.

[0003] The aforementioned device lacks a structure that allows the dispensing pump to be adapted to different solution bottles. This means that most existing dispensing pumps can only be used with the original size or a single size. If other sizes of solution bottles are used to hold formalin, a corresponding dispensing pump must be selected, which is too cumbersome and inconvenient to use. Utility Model Content

[0032] Example 1

[0033] Reference Figures 1-6 This is the first embodiment of the present utility model. This embodiment provides a connection limiting mechanism, including a connection component 100, which includes a housing 101, a cylindrical body 200 disposed on one side of the housing 101, and a rotating component 500 disposed on one side of the cylindrical body 200; and, a handle 102 is fixedly connected to the top of the housing 101, a side groove 201 is opened on one side of the cylindrical body 200, a rotating block 202 is rotatably connected inside the side groove 201, a water outlet rod 203 is fixedly connected to one side of the rotating block 202, a connection hole 204 is opened on one side of the cylindrical body 200, and a limiting ring 205 is fixedly connected to the side of the rotating cylinder 401 away from the connection hole 204. The device includes a housing 101, a cylindrical body 200 disposed on the top of the housing 101, a limiting component 300 disposed on the bottom of the cylindrical body 200, and an installation component 400 disposed on the bottom of the cylindrical body 200.

[0034] Furthermore, a handle 102 is fixedly connected to the top of the housing 101.

[0035] Furthermore, a side groove 201 is provided on one side of the cylinder 200, a rotating block 202 is rotatably connected inside the side groove 201, a water outlet rod 203 is fixedly connected to one side of the rotating block 202, a connecting hole 204 is provided on the lower surface of the cylinder 200, a limit ring 205 is fixedly connected to the upper surface of the rotating cylinder 401, and a limit groove 206 is provided on the lower surface of the cylinder 200.

[0036] The limiting ring 205 is rotatably connected inside the limiting groove 206, and the water outlet rod 203 is set on one side of the side groove 201.

[0037] Furthermore, the cylinder 200 is conveniently installed on the top of the housing 101 via the limiting component 300 and the mounting component 400. The cylinder 200 facilitates the pumping out of the formalin solution inside the housing 101. At the same time, a side groove 201 is provided on one side of the cylinder 200. The rotating block 202 facilitates the movement of the water outlet rod 203 to be stored inside the side groove 201 or opened on one side of the cylinder 200.

[0038] Furthermore, a rotating shaft 501 is provided inside the rotating component 500, and a fixed rod 502 is connected to the rotating shaft 501. The fixed rod 502 is fixedly connected to the rotating block 202. A telescopic platform 501a is fixedly connected to the side of the rotating shaft 501. A telescopic spring 501c is provided inside the telescopic platform 501a. One end of the telescopic platform 501a is fixedly connected to the telescopic spring 501c. The end of the telescopic spring 501c away from the telescopic platform 501a is fixedly connected to the telescopic plate 501b. The telescopic plate 501b is located in the internal groove of the telescopic platform 501a.

[0039] Specifically, when the telescopic platform 501a is in operation and the telescopic spring 501c releases its maximum elastic potential energy, the telescopic plate 501b remains half inside the telescopic platform 501a, with the other half outside. During the rotation of the rotating block 202, the fixed rod 502 rotates simultaneously. At this time, the fixed rod 502 drives the rotating shaft 501 to rotate. The telescopic plate 501b, located inside the telescopic platform 501a on the rotating shaft 501, contacts the locking block 503. The telescopic plate 501b has an inclined surface on the side near the locking block 503. When the inclined surface of the telescopic plate 501b contacts the locking block 503, the operator applies force to make the inclined surface of the telescopic plate 501b contact the locking block 503 and compress the telescopic spring 501c. At this time, the telescopic plate 501b is squeezed into the interior of the telescopic platform 501a. After the rotation causes the telescopic plate 501b to pass through the locking block 503, the telescopic plate 501b is released by the elastic potential energy of the telescopic spring 501c and extends out. At this time, the telescopic plate 501b still remains half inside the telescopic platform 501a to prevent it from disengaging from the telescopic platform 501a.

[0040] Specifically, the telescopic platform 501a can rotate at an angle of 90°, and the locking block 503 is set within this 90° rotation. When the telescopic plate 501b rotates to one side of the locking block 503, the water outlet rod 203 retracts into the side groove 201. Without external force, the water outlet rod 203 remains locked. After being subjected to external force, the water outlet rod 203 is lifted. At this time, the telescopic plate 501b rotates 90° and remains perpendicular to the side groove 201, which facilitates the collection of solution. At this time, the telescopic plate 501b moves to the other side of the locking block 503. Without external force, the telescopic plate 501b will be unable to move into the side groove 201. At this time, it remains horizontal under the action of gravity. At this time, the water outlet rod 203 remains perpendicular to the side groove 201 and is in a stationary state.

[0041] Example 2

[0042] Reference Figures 1-6 This is the second embodiment of the present invention. Unlike the previous embodiment, it also includes an installation component 400. The installation component 400 includes a rotating cylinder 401 and a connecting strip 402. The rotating cylinder 401 is rotatably connected to the lower surface of the cylinder body 200, and the connecting strip 402 is fixedly connected inside the rotating cylinder 401.

[0043] The mounting component 400 also includes a connecting groove 403, a clamping block 404, a vertical bar 405, and a limiting rod 406. The connecting groove 403 is formed on the upper surface of the connecting bar 402. The clamping block 404 is rotatably connected to the inside of the rotating cylinder 401. The vertical bar 405 is fixedly connected to the upper surface of the clamping block 404, and the limiting rod 406 is fixedly connected to the lower surface of the clamping block 404.

[0044] The limiting rod 406 is movably connected inside the connecting groove 403, and the vertical bar 405 is movably connected inside the hexagonal slot 306.

[0045] The limiting component 300 includes a limiting cylinder 301, a retaining strip 302, a protruding ring 303, a limiting strip 304, a sliding groove 305, and a hexagonal retaining groove 306. The limiting cylinder 301 is slidably connected to the outer surface of the cylinder 200. The retaining strip 302 is fixedly connected inside the limiting cylinder 301. The protruding ring 303 is fixedly connected to the upper surface of the limiting cylinder 301. The limiting strip 304 is fixedly connected inside the limiting cylinder 301. The sliding groove 305 is opened on one side of the cylinder 200, and the hexagonal retaining groove 306 is opened on the lower surface of the cylinder 200.

[0046] The locking strip 302 is movably engaged with the outer surface of the rotating drum 401, and the limiting strip 304 is slidably connected to the inside of the slide groove 305.

[0047] Further explanation is needed: By rotating the rotating drum 401, the connecting strip 402 is rotated. At this time, the clamping block 404 inside the connecting strip 402 rotates inside the rotating drum 401. The clamping block 404 can be opened and can be fitted onto the outer surface of the bottle mouth. Then, by rotating the rotating drum 401, the clamping block 404 can be clamped onto the outside of the bottle mouth. Then, the limiting cylinder 301 is pushed down so that the locking strip 302 is engaged with the outer surface of the rotating drum 401, limiting and locking the rotating drum 401, so that the cylinder 200 is installed on the top of the box 101.

[0048] In summary, during use, the cylinder 200 is easily installed on the top of the box 101 via the limiting component 300 and the mounting component 400. The cylinder 200 facilitates the removal of the formalin solution inside the box 101. Meanwhile, a side groove 201 is provided on one side of the cylinder 200. The rotating block 202 facilitates the movement of the water outlet rod 203 to be stored inside the side groove 201 or opened on one side of the cylinder 200. The mounting component 400 is designed to accommodate bottle openings of different sizes of the box 101. The limiting component 300 is provided on the outside of the mounting component 400 to limit and lock the rotating cylinder 401, thus facilitating the fixation of the cylinder 200.

[0049] When it is necessary to accommodate bottle necks of different sizes, first push the limiting cylinder 301 upward so that the limiting cylinder 301 disengages from the outer surface of the rotating cylinder 401. Then rotate the rotating cylinder 401 so that the rotating cylinder 401 drives the connecting strip 402 to rotate. At this time, the clamping block 404 inside the connecting strip 402 rotates inside the rotating cylinder 401. At this time, the clamping block 404 can be opened and can be fitted onto the outer surface of the bottle neck. Then, by rotating the rotating cylinder 401, the clamping block 404 can be clamped onto the outside of the bottle neck. Then push the limiting cylinder 301 downward so that the locking strip 302 is engaged with the outer surface of the rotating cylinder 401, limiting and locking the rotating cylinder 401, so that the cylinder body 200 is installed on the top of the box body 101. This device is convenient to accommodate bottle necks of different sizes.
