Filtering clamp for pharmaceutical intermediates

Abstract

This utility model relates to the field of filter clip technology, specifically a filter clip for pharmaceutical intermediates, including a U-shaped spring. The advantages of this utility model are: by pulling the two clamping springs with a handle, the inclined clamping block is pulled out of the inclined slot, allowing direct removal of the clamping plate. By inserting a new clamping plate into the connecting sleeve, the inclined plate is automatically pushed open by the inclined surface guide. Further pushing causes the inclined plate to be pushed into the inclined slot by the clamping spring, thus enabling the removal and replacement of any clamping plate for easy replacement. By pushing the clamping plate to slide within the connecting sleeve, the inclined plate is automatically pushed open by the inclined surface guide. Further pushing causes the inclined plate to be pushed into the inclined slot by the clamping spring, thereby controlling the angled clamping block to engage with any inclined slot. This allows for adjustment of the length of the clamping plate extending beyond the U-shaped spring, thereby changing the length of the clamping arm and improving practicality.

[0005] Therefore, one objective of this invention is to provide a pharmaceutical intermediate filter clip to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a pharmaceutical intermediate filter clip, including a U-shaped spring. Connecting sleeves are fixedly connected to both sides of the outer wall of the U-shaped spring. Strip-shaped spring holes are formed in the middle of both sides of the connecting sleeve. Clamping springs are fixedly connected to one side of the inner wall of each of the two strip-shaped spring holes. An inclined clamping block is fixedly connected to one end of each of the two clamping springs. A handle is fixedly connected to the end of the clamping spring near the inclined clamping block on the outer wall of the connecting sleeve. Clamping plates are slidably connected to the inner wall of the connecting sleeve. Filter cages are fixedly connected to the bottom of each of the two clamping plates. The openings of the two filter cages correspond to each other. Several inclined slots are formed on the top of both sides of the two clamping plates. Each of the inclined slots can engage with the inclined clamping block. The width of the two clamping plates matches the width of the inner wall of the connecting sleeve, and the thickness of the two clamping plates matches the thickness of the inner wall of the connecting sleeve.

[0007] Preferably, in any of the above embodiments, the handle protrudes from the strip spring hole outside the connecting sleeve, the diameter of the handle is greater than the width of the strip spring hole, the width of the clamping spring is adapted to the width of the inner wall of the strip spring hole, and the length of the clamping spring is adapted to the length of the inner wall of the strip spring hole.

[0008] The technical effect achieved by adopting the above solution is that it allows the clamping spring to fully utilize the reserved space on the inner wall of the strip spring hole.

[0009] Preferably, in any of the above solutions, a fixing sleeve is fitted together between the outer wall of the connecting sleeve and the outer wall of the U-shaped spring piece. The length of the fixing sleeve is less than the distance from one end of the strip spring piece hole to the top of the connecting sleeve, and the length of the fixing sleeve is adapted to the length of the strip spring piece hole.

[0010] The technical effect achieved by adopting the above solution is that the pulling out of the clamping spring can be restricted by the blocking of the fixed sleeve, so as to fix the position.

[0011] Preferably, in any of the above embodiments, a spring hole is provided in the middle of one side of the fixed sleeve, a pressing spring is fixedly connected to one side of the inner wall of the spring hole, and a damping block is fixedly connected to one end of the pressing spring. The damping block presses against the outer wall of the connecting sleeve under the push of the pressing spring.

[0012] The technical effect achieved by adopting the above solution is that the damping block can be pressed by the clamping spring to stably fix the fixed sleeve to the outer wall of the connecting sleeve, while facilitating pushing and adjustment.

[0013] Preferably, in any of the above embodiments, the surfaces of the two filter cages are provided with a plurality of filter holes, and the two filter cages are arranged symmetrically.

[0014] The technical effect achieved by adopting the above solution is that the two filter cages can clamp the pharmaceutical intermediate from the left and right, and can wrap the pharmaceutical intermediate so that the liquid medicine can be filtered out through a number of filter holes.

[0015] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. This pharmaceutical intermediate filter clamp allows for easy removal of the clamping plate by pulling two clamping springs with a handle. This pulls up the inclined clamping block out of the inclined slot, allowing the clamping plate to be directly removed. By inserting a new clamping plate into the connecting sleeve, the inclined clamping block is automatically pushed open by the inclined surface guide. Continuing to push the clamping springs push the inclined clamping block into the inclined slot, thus enabling the removal and replacement of any clamping plate for convenient replacement.

[0016] 2. This pharmaceutical intermediate filter clamp, by pushing the clamping plate to slide in the connecting sleeve, can automatically push open the inclined plate block guided by the inclined plate block. Then, by continuing to push, the inclined plate block is pushed into the inclined plate slot by the clamping spring, thereby controlling the inclined plate block to be inserted into the interior of any inclined plate slot, realizing the length of the U-shaped spring extending from the clamping plate, and thus changing the length of the clamping arm, improving practicality.

Inclined clamping blocks 12 are fixedly connected to one end of each of the two clamping springs 11. A handle 4 is fixedly connected to the end of the clamping spring 11 on one side of the outer wall of the connecting sleeve 2 near the inclined clamping block 12. Clamping plates 5 are slidably connected to the inner wall of the connecting sleeve 2. Filter cages 7 are fixedly connected to the bottom of each of the two clamping plates 5. The openings of the two filter cages 7 correspond to each other. Several inclined grooves 6 are opened on the top of both sides of the two clamping plates 5. The inclined grooves 6 can all engage with the inclined clamping blocks 12. The width of the two clamping plates 5 is adapted to the width of the inner wall of the connecting sleeve 2, and the thickness of the two clamping plates 5 is adapted to the thickness of the inner wall of the connecting sleeve 2.

[0021] As an optional technical solution of this utility model, the handle 4 protrudes from the strip spring hole 3 outside the connecting sleeve 2. The diameter of the handle 4 is greater than the width of the strip spring hole 3. The width of the clamping spring 11 is adapted to the width of the inner wall of the strip spring hole 3, and the length of the clamping spring 11 is adapted to the length of the inner wall of the strip spring hole 3, so that the clamping spring 11 can make full use of the reserved space of the inner wall of the strip spring hole 3.

[0022] As an optional technical solution of this utility model, a fixing sleeve 8 is sleeved between the outer wall of the connecting sleeve 2 and the outer wall of the U-shaped spring piece 1. The length of the fixing sleeve 8 is less than the distance from one end of the strip spring piece hole 3 to the top of the connecting sleeve 2. The length of the fixing sleeve 8 is adapted to the length of the strip spring piece hole 3, so that the fixing sleeve 8 can slide to cover the outside of the strip spring piece hole 3 or away from the strip spring piece hole 3. By blocking the fixing sleeve 8, the pulling out of the clamping spring piece 11 can be restricted so as to fix the position.

[0023] As an optional technical solution of this utility model, a spring hole 9 is provided in the middle of one side of the fixed sleeve 8. A pressing spring 10 is fixedly connected to one side of the inner wall of the spring hole 9. A damping block is fixedly connected to one end of the pressing spring 10. The damping block presses against the outer wall of the connecting sleeve 2 under the push of the pressing spring 10. By pressing the damping block with the pressing spring 10, the fixed sleeve 8 can be stably fixed to the outer wall of the connecting sleeve 2, and it is also easy to push and adjust.

[0024] As an optional technical solution of this utility model, the surfaces of the two filter cages 7 are provided with a number of filter holes, and the two filter cages 7 are symmetrically arranged so that the two filter cages 7 can clamp the pharmaceutical intermediate from the left and right, and can wrap the pharmaceutical intermediate so that the liquid medicine can be filtered out through the number of filter holes.

[0025] A pharmaceutical intermediate filter clip, the working principle of which is as follows: 1) Pull the two clamping springs 11 up by pulling the handle 4, thereby pulling the inclined plate 12 out of the inclined groove 6, so that the clamping plate 5 can be pulled out directly; 2) By inserting the new clamping plate 5 into the connecting sleeve 2, the inclined plate 12 is automatically pushed open by the inclined plate 12, and then pushed further, so that the inclined plate 12 is pushed into the inclined slot 6 by the clamping spring 11, thereby enabling the disassembly and replacement of any clamping plate 5. 3) By pushing the clamping plate 5 to slide on the connecting sleeve 2, the inclined plate 12 can be automatically pushed open by the inclined plate 12. Then, by continuing to push, the inclined plate 12 is pushed into the inclined groove 6 by the clamping spring 11, thereby controlling the inclined plate 12 to be inserted into any inclined groove 6, so as to realize the length of the U-shaped spring 1 extending from the clamping plate 5, and thus change the length of the clamping arm.

[0026] In summary, this pharmaceutical intermediate filter clamp allows for easy removal of the clamping plate 5 by pulling up the two clamping springs 11 via the handle 4, which in turn pulls the inclined clamping block 12 out of the inclined groove 6. A new clamping plate 5 can be inserted into the connecting sleeve 2, and the inclined surface of the inclined clamping block 12 automatically pushes it open. Further pushing causes the clamping springs 11 to push the inclined clamping block 12 into the inclined groove 6, enabling the removal and replacement of any clamping plate 5. By sliding the clamping plate 5 within the connecting sleeve 2, the inclined surface of the inclined clamping block 12 automatically pushes it open. Further pushing causes the clamping springs 11 to push the inclined clamping block 12 into the inclined groove 6, thus controlling the insertion of the inclined clamping block 12 into any inclined groove 6. This allows for adjustment of the length of the U-shaped springs 1 extending from the clamping plate 5, thereby changing the length of the clamping arm and improving practicality.
