Abstract
Description
Technical Field
[0001] This utility model relates to the field of storage tank technology, and in particular to a raw material storage tank for PVC granules used to prevent rodents and ants. Background Technology
[0002] In the fields of power, communications, and construction, PVC granules are widely used in the manufacture of products such as cable sheaths and pipes due to their excellent insulation, corrosion resistance, and mechanical strength. However, traditional PVC materials are easily damaged by rodents and ants in outdoor or underground environments, leading to equipment damage, short circuits, or even safety accidents.
[0003] Currently, in the production process of PVC rodent-repellent granules, raw material storage tanks are usually used to store PVC resin, plasticizers, stabilizers, and rodent-repellent additives. However, most existing storage tanks adopt an open design or a simple cover structure, lacking an effective fastening and sealing device. Open or unfastened storage tanks cannot effectively isolate air and moisture, resulting in a decline in the performance of rodent-repellent additives and affecting the rodent-repellent effect of the final product. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing technology lacks a sealed design, and external dust, insects or other pollutants can easily enter the tank. To address this, we propose a raw material storage tank for PVC granules that are rodent-proof.
[0005] To achieve the above objectives, this application adopts the following technical solution: a raw material storage tank for PVC granule rodent-proof material, comprising a storage tank body, a feeding block fixedly connected to the top of the storage tank body, a rotating column rotatably connected inside the feeding block, a cover plate provided inside the rotating column, adjustment grooves opened on both sides of the rotating column, a push block slidably connected inside the adjustment groove, an insertion rod fixedly connected to the side of the push block near the inside of the adjustment groove, arc blocks fixedly connected to both sides inside the feeding block, and insertion holes opened on both sides of the cover plate.
[0006] Preferably, both ends of the adjusting groove are provided with sliding grooves, and both ends of the push block are fixedly connected with sliders, the surface of the sliders being slidably connected to the inside of the sliding grooves.
[0007] Preferably, the size of the plug rod is adapted to the size of the socket, and the surface of the plug rod is inserted into the interior of the socket.
[0008] Preferably, a sealing gasket is installed at the bottom of the inside of the feed block.
[0009] Preferably, the feed block has two annular grooves inside, and an annular block is fixedly connected to the outer diameter surface of the cover plate, with the surface of the annular block slidingly connected to the inside of the annular groove.
[0010] Preferably, a return spring is fixedly connected to the bottom of the inside of the feed block, and the top of the return spring is fixedly connected to the bottom of the ring block.
[0011] Preferably, a storage spring is fixedly connected to the side of the push block near the insertion rod, and the side of the storage spring away from the push block is fixedly connected to the inside of the adjustment groove.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] In this invention, the operator places the cover plate inside the rotating column and rotates the column, causing the rotating column to move the push block and the insertion rod. The push block then contacts the thicker end of the arc block, causing the arc block to push the push block to insert the insertion rod into the insertion hole for fixation. This ensures that the cover plate is securely placed inside the rotating column, preventing rodents and ants from entering. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0021] Reference Figure 1 - Figure 5As shown, this utility model provides a technical solution: a raw material storage tank for PVC granules used to repel rodents and ants, including a storage tank body 1. A feeding block 2 is fixedly connected to the top of the storage tank body 1. A rotating column 3 is rotatably connected inside the feeding block 2. A cover plate 4 is provided inside the rotating column 3. Adjustment grooves 5 are provided on both sides of the rotating column 3. A push block 6 is slidably connected inside the adjustment groove 5. An insertion rod 7 is fixedly connected to the side of the push block 6 near the inside of the adjustment groove 5. Arc blocks 8 are fixedly connected to both sides of the inside of the feeding block 2. Insertion holes 9 are provided on both sides of the cover plate 4. By placing the cover plate 4 inside the rotating column 3 and rotating the rotating column 3, the rotating column 3 drives the push block 6 and the insertion rod 7 to move, and the push block 6 contacts the thicker end of the arc block 8. The arc block 8 pushes the push block 6 to drive the insertion rod 7 to insert into the insertion hole 9 for fixation, thereby making the cover plate 4 stable inside the rotating column 3 and preventing rodents and ants from entering.
[0022] Reference Figure 4 As shown in this embodiment: both ends of the adjustment groove 5 are provided with sliding grooves 10, and both ends of the push block 6 are fixedly connected with sliders 11. The surface of the sliders 11 is slidably connected to the inside of the sliding groove 10. When the operator moves the push block 6, the push block 6 drives the sliders 11 to slide inside the sliding groove 10. Through the above settings, the movement of the push block 6 is more stable, the shaking is reduced, and the overall structural stability is improved.
[0023] Reference Figure 4 As shown, in this embodiment: the size of the insertion rod 7 is adapted to the size of the insertion hole 9, and the surface of the insertion rod 7 is inserted into the interior of the insertion hole 9. By adapting the size of the insertion rod 7 to the size of the insertion hole 9, the insertion rod 7 can be stably inserted into the interior of the insertion hole 9, thereby enhancing the stability of the structure. When the push block 6 slides inside the adjusting groove 5, it drives the insertion rod 7 to move along the interior of the insertion hole 9. This design not only realizes the effective connection between components, but also ensures the smoothness and accuracy of the overall device during operation.
[0024] Reference Figure 4 As shown in this embodiment: a sealing gasket 12 is installed at the bottom of the inside of the feed block 2. By installing the sealing gasket 12 at the bottom of the inside of the feed block 2, the raw material is effectively prevented from directly contacting the inside of the storage tank, avoiding moisture or contamination of the raw material, and ensuring the purity and quality of the raw material.
[0025] Reference Figure 5As shown in this embodiment: the feed block 2 has two annular grooves 13 inside, and the outer diameter surface of the cover plate 4 is fixedly connected to an annular block 14. The surface of the annular block 14 is slidably connected to the inside of the annular groove 13. When the operator rotates the cover plate 4, the cover plate 4 drives the annular block 14 to slide inside the annular groove 13. Through the above arrangement, the cover plate 4 is more stable during rotation, reducing shaking and improving work efficiency. At the same time, the sliding setting of the annular block 14 inside the annular groove 13 also plays a guiding role, ensuring the accuracy of the rotation of the cover plate 4. In addition, the cooperative design of the annular groove 13 and the annular block 14 also enhances the stability of the overall structure and extends the service life.
[0026] Reference Figure 4 As shown in this embodiment: a return spring 15 is fixedly connected to the bottom of the feed block 2. The top of the return spring 15 is fixedly connected to the bottom of the ring block 14. When the operator rotates the rotating column 3, the rotating column 3 drives the ring block 14 to twist the return spring 15 to store force. At the same time as the rotating column 3 rotates, the operator cancels the contact between the push block 6 and the arc block 8, and pushes the push block 6 under the action of the rebound force of the stored spring 16, thereby releasing the limit between the insertion rod 7 and the insertion hole 9. When the operator releases the rotating column 3, under the action of the rebound force of the return spring 15, the rotating column 3 quickly rotates in the opposite direction, so that the arc block 8 and the push block 6 re-contact, and drives the insertion rod 7 to insert into the insertion hole 9 for limit.
[0027] Reference Figure 4 As shown in this embodiment: a storage spring 16 is fixedly connected to the side of the push block 6 near the insertion rod 7, and the side of the storage spring 16 away from the push block 6 is fixedly connected to the inside of the adjustment groove 5. When the operator pushes the push block 6 to push the insertion rod 7, the push block 6 compresses the storage spring 16 to store force, and drives the insertion rod 7 to be inserted into the insertion hole 9 for fixation. When the operator releases the push block 6, the insertion rod 7 can be easily pulled out of the insertion hole 9 under the action of the rebound force of the storage spring 16, thereby realizing the quick fixation and unlocking of the insertion rod 7.
[0028] Working principle: The operator places the cover plate 4 inside the rotating column 3 and rotates the rotating column 3, causing the rotating column 3 to move the push block 6 and the insertion rod 7. The push block 6 then contacts the thicker end of the arc block 8, causing the arc block 8 to push the push block 6, which in turn moves the insertion rod 7 into the insertion hole 9 for fixation. This secures the cover plate 4 inside the rotating column 3, preventing rodents and ants from entering. When the operator moves the push block 6, the push block 6 causes the slider 11 to slide inside the groove 10. This design makes the movement of the push block 6 more stable, reduces shaking, and improves the overall structural stability. The dimensions of the insertion rod 7 and the insertion hole... The size of the insertion rod 7 is matched to the size of the insertion hole 9, which allows the insertion rod 7 to be stably inserted into the insertion hole 9, thereby enhancing the stability of the structure. When the push block 6 slides inside the adjusting groove 5, it drives the insertion rod 7 to move along the inside of the insertion hole 9. This design not only realizes the effective connection between components, but also ensures the smoothness and accuracy of the overall device during operation. The sealing gasket 12 installed at the bottom of the feed block 2 effectively prevents the raw material from directly contacting the inside of the storage tank, avoiding moisture or contamination of the raw material, and ensuring the purity and quality of the raw material. When the operator rotates the cover plate 4, the cover plate 4 drives the ring block 14 in the ring groove. The sliding mechanism inside groove 13, as described above, makes the cover plate 4 more stable during rotation, reducing wobbling and improving work efficiency. Simultaneously, the sliding mechanism of ring block 14 within the ring groove 13 also serves as a guide, ensuring the accuracy of cover plate 4's rotation. Furthermore, the cooperative design between ring groove 13 and ring block 14 enhances the overall structural stability and extends service life. When the operator rotates the rotating column 3, the rotating column 3 drives the ring block 14 to twist and the return spring 15 to store force. Simultaneously, as the rotating column 3 rotates, the operator cancels the contact between push block 6 and arc block 8, and under the action of the rebound force of the stored spring 16... Pushing the push block 6 releases the limit between the insertion rod 7 and the insertion hole 9. When the operator releases the rotating column 3, the rotating column 3 quickly rotates in the opposite direction under the action of the return spring 15, causing the arc block 8 to re-contact with the push block 6 and driving the insertion rod 7 to be inserted into the insertion hole 9 for limitation. When the operator pushes the push block 6 to push the insertion rod 7, the push block 6 compresses the storage spring 16 to store force and drives the insertion rod 7 to be inserted into the insertion hole 9 for fixation. When the operator releases the push block 6, the insertion rod 7 can be easily pulled out of the insertion hole 9 under the action of the return spring 16, thus realizing the quick fixation and unlocking of the insertion rod 7.
