Description

Technical Field

[0001] This utility model relates to the field of funnel technology, and in particular to a telescopic funnel that can conduct static electricity. Background Technology

[0002] Gasoline is produced by refining various gasoline components, such as straight-run gasoline components, catalytic cracking gasoline components, and catalytic reforming gasoline components, and then blending them with high-octane components. It is mainly used as fuel for spark-ignition internal combustion engines in automobiles.

[0003] When refueling a car, a fuel dispenser is needed. However, during fuel dispenser maintenance, residual fuel may leak. In this case, a funnel is needed to guide the fuel from the dispenser into a fuel container for collection. However, traditional funnels are mostly of fixed length and cannot be flexibly adjusted according to the height of the fuel container or the location of the residual fuel leak. When dealing with fuel containers of different heights or with significant differences in the location of the leak, it is inconvenient to connect them, leading to easy spillage during the collection of residual fuel and increasing operational inconvenience. Gasoline is a flammable and explosive substance. During the transfer process through the funnel, the friction between the fuel and the inner wall of the funnel will generate static electricity. Most existing funnels do not have the function of conducting static electricity. Static electricity accumulation may cause sparks if it reaches a certain level, posing a risk of igniting gasoline vapor and causing a safety accident. Therefore, it is necessary to design a telescopic funnel that can conduct static electricity to solve the above problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a telescopic funnel capable of conducting static electricity, comprising: The funnel body is equipped with a static-dissipating telescopic mechanism. The electrostatic conductive telescopic mechanism includes a telescopic tube, a conductive base, a rod, a connecting cylinder, a turntable, a connecting rod, a square plate, and a limiting block; The telescopic tube is slidably and sealed on the funnel body. The conductive seat is fixedly sleeved on the outside of the telescopic tube. The top of the rod is fixedly connected to the funnel body. The connecting cylinder is fixedly installed on the top of the conductive seat. The rod is slidably installed inside the connecting cylinder. The turntable is rotatably sleeved on the outside of the funnel body. The connecting rod is fixedly connected to the turntable and the square plate. The limiting block is fixedly installed on the connecting cylinder. The square plate abuts against two adjacent limiting blocks.

[0007] A further feature of this invention is that the electrostatic conductive telescopic mechanism includes a positioning component, a plate, a spring, a wire, a metal sleeve, and a grounding component. The positioning component is slidably mounted on the rod, the plate is fixedly mounted on the positioning component, the spring is fixedly mounted between the plate and the rod, the positioning component is engaged with the turntable, the wire is fixedly mounted between the conductive base and the metal sleeve, and the metal sleeve is fitted onto the grounding component.

[0008] A further feature of this invention is that a baffle is fixedly sleeved on the outside of the grounding component, and the bottom of the metal sleeve contacts the baffle.

[0009] By adopting the above technical solution, the metal sleeve can be limited.

[0010] A further feature of this invention is that the grounding component is threadedly connected to a threaded abutment sleeve on its outer side, and the bottom of the threaded abutment sleeve abuts against a metal sleeve.

[0011] A further feature of this invention is that a sealing gasket is fixedly provided on the funnel body, and the telescopic tube is in sealing contact with the inner side of the sealing gasket.

[0012] By adopting the above technical solution, the sealing performance during telescopic adjustment can be guaranteed.

[0013] A further feature of this invention is that two limiting discs are fixedly sleeved on the outer side of the funnel body, the turntable is in contact with the limiting discs, and a control lever is fixedly installed on the turntable.

[0014] By adopting the above technical solution, the rotation of the turntable is facilitated.

[0015] A further feature of this invention is that a movable hole is provided on the rod body, and the positioning component is slidably installed in the movable hole.

[0016] A further feature of this invention is that a positioning groove is provided on the turntable, and the positioning component is engaged with the positioning groove.

[0017] The beneficial effects of this utility model are: This invention utilizes a static-dissipating telescopic mechanism. Through the sliding and sealing cooperation between the telescopic tube and the funnel body, combined with the sliding of the rod within the connecting cylinder, the overall length can be quickly adjusted. With the help of the linkage structure of the turntable, connecting rod, square plate, and limiting block, the length can be securely locked after adjustment, ensuring precise docking with oil drums and leak points of different heights. This reduces residual oil spillage, simplifies operation, and improves collection efficiency. Static electricity generated by oil friction is conducted sequentially through the telescopic tube, conductive seat, wire, and metal sleeve to the grounding component and then to the earth, preventing static sparks from causing explosions or fires. It is particularly suitable for flammable and explosive environments such as gas stations, significantly improving operational safety. Attached Figure Description

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0025] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] See Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model provides a telescopic funnel that can conduct static electricity, comprising: The funnel body 1 is equipped with a static-dissipating telescopic mechanism. It should be noted that this mechanism facilitates quick and easy telescopic adjustment of the funnel, making it convenient to operate. Furthermore, it can dissipate static electricity during use, ensuring safety during use. The electrostatic discharge telescopic mechanism includes a telescopic tube 2, a conductive base 3, a rod 4, a connecting cylinder 5, a turntable 6, a connecting rod 7, a square plate 8, and a limiting block 9; The telescopic tube 2 is slidably and sealed on the funnel body 1. The conductive seat 3 is fixedly sleeved on the outside of the telescopic tube 2. The top of the rod 4 is fixedly connected to the funnel body 1. The connecting cylinder 5 is fixedly installed on the top of the conductive seat 3. The rod 4 is slidably installed inside the connecting cylinder 5. The turntable 6 is rotatably sleeved on the outside of the funnel body 1. The connecting rod 7 is fixedly connected to the turntable 6 and the square plate 8. The limiting block 9 is fixedly installed on the connecting cylinder 5. The square plate 8 abuts against the two adjacent limiting blocks 9.

[0027] With the above structure, when the funnel needs to be extended or retracted, the turntable 6 is rotated, causing the connecting rod 7 to drive the square plate 8 to rotate, so that the square plate 8 separates from the limiting block 9. Then, the funnel body 1 and the conductive base 3 are pulled vertically to extend or retract the funnel. After the adjustment is completed, the turntable 6 is rotated in the opposite direction, so that the square plate 8 moves between the two adjacent limiting blocks 9, thus performing the limiting treatment after extension or retraction.

[0028] Specifically, the electrostatic discharge telescopic mechanism also includes a positioning component 10, a plate 11, a spring 12, a wire 13, a metal sleeve 14, and a grounding component 15. The positioning component 10 is slidably mounted on the rod 4, the plate 11 is fixedly mounted on the positioning component 10, the spring 12 is fixedly mounted between the plate 11 and the rod 4, the positioning component 10 is engaged with the turntable 6, the wire 13 is fixedly mounted between the conductive seat 3 and the metal sleeve 14, and the metal sleeve 14 is fitted onto the grounding component 15.

[0029] Through the above structure, the conductive base 3 can conduct the static electricity generated on the funnel to the grounding member 15 through the wire 13 and the metal sleeve 14, ensuring the safety of introducing the oil from the fuel dispenser into the oil drum. After the turntable 6 rotates back to its original position, the spring 12 resets, causing the plate 11 to move the positioning member 10, so that the positioning member 10 is locked onto the turntable 6, limiting the turntable 6. When extension and retraction adjustment is required, the positioning member 10 must first be pulled to remove the positioning member 10 from the turntable 6, releasing the limitation on the turntable 6. When using the funnel, the metal sleeve 14 is put on the grounding member 15, and then the threaded abutment sleeve 17 is screwed on, thus fixing the metal sleeve 14 on the grounding member 15.

[0030] Specifically, a baffle 16 is fixedly sleeved on the outside of the grounding component 15, and the bottom of the metal sleeve 14 contacts the baffle 16. A threaded clamping sleeve 17 is threadedly connected to the outside of the grounding component 15, and the bottom of the threaded clamping sleeve 17 abuts against the metal sleeve 14. It should be noted that this facilitates locking the metal sleeve 14 onto the grounding component 15.

[0031] Specifically, a sealing gasket is fixedly installed on the funnel body 1, and the telescopic tube 2 is in sealing contact with the inner side of the sealing gasket. It should be noted that this ensures the sealing between the telescopic tube 2 and the funnel body 1.

[0032] Specifically, two limiting discs are fixedly sleeved on the outer side of the funnel body 1, and the turntable 6 is in contact with the limiting discs. A control lever is fixedly installed on the turntable 6 to facilitate the rotation of the turntable 6.

[0033] Specifically, a moving hole is provided on the rod body 4, and the positioning part 10 is slidably installed in the moving hole. A positioning groove is provided on the turntable 6, and the positioning part 10 is engaged with the positioning groove. It should be noted that this allows the positioning part 10 to move stably in the lateral direction and limits the turntable 6.

[0034] Working principle: S1: When using this funnel to collect residual oil leaked from the fuel dispenser, the length of the funnel must first be adjusted according to the height of the oil drum and the location of the residual oil leak. During operation, first pull the plate 11 to drive the positioning part 10 to slide in the moving hole of the rod 4, so that the positioning part 10 is disengaged from the positioning groove on the turntable 6. At this time, the spring 12 is compressed. Then, the turntable 6 is rotated by the control lever on the turntable 6. The turntable 6 rotates between the two limiting plates on the outside of the funnel body 1, driving the connecting rod 7 and the square plate 8 to rotate, so that the square plate 8 is separated from the limiting block 9 on the connecting cylinder 5, and the limitation on the telescopic tube 2 is released. S2: Subsequently, pull the funnel body 1 or the conductive base 3 vertically. Since the telescopic tube 2 is slidably and sealed on the funnel body 1 and the rod 4 slides in the connecting cylinder 5, the telescopic tube 2 will extend and retract relative to the funnel body 1 to adjust the length of the funnel. After adjusting to the appropriate length, rotate the turntable 6 in the opposite direction to move the square plate 8 between the two adjacent limit blocks 9 to limit the telescopic tube 2. At this time, release the plate 11, the spring 12 returns to its original position, and pushes the plate 11 and the positioning part 10 to move. The positioning part 10 is re-engaged into the positioning groove of the turntable 6 to complete the fixation of the turntable 6 and ensure the stability of the telescopic length. S3: In terms of static electricity conduction, the metal sleeve 14 is placed on the grounding component 15, so that the bottom of the metal sleeve 14 contacts the baffle 16. Then, the threaded sleeve 17 on the outside of the grounding component 15 is tightened so that its bottom abuts against the metal sleeve 14, thus fixing the metal sleeve 14 on the grounding component 15. Since the conductive seat 3 is fixedly sleeved on the outside of the telescopic tube 2, and the wire 13 connects the conductive seat 3 and the metal sleeve 14, the static electricity generated by friction during the transfer of residual oil in the funnel will be conducted to the grounding component 15 in sequence through the telescopic tube 2, the conductive seat 3, the wire 13, and the metal sleeve 14, and finally conducted to the ground, thus avoiding static electricity accumulation that could cause safety accidents.

[0035] The above provides a detailed description of a telescopic funnel capable of conducting static electricity. Specific embodiments have been used to illustrate the principles and implementation methods of this utility model. These embodiments are merely illustrative and are intended to aid in understanding the method and core concepts of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of this utility model.
