Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, and in particular to a drip-proof connection structure. Background Technology

[0002] The production of fragrances and flavorings requires many liquid raw materials, which are often stored in large drums in factories. When in use, the raw materials in the drums need to be released through pipes. However, after the raw materials are released, the raw materials temporarily left in the pipes will drip, causing pollution to the ground and equipment.

[0003] A search revealed Chinese Patent Publication No. CN221258103U, which discloses a quick-opening valve anti-drip device, belonging to the technical field of tobacco auxiliary equipment. It includes two locking blocks installed on the feed pipeline of the quick-opening valve. The inner sides of the locking blocks have an arc-shaped groove and a rectangular groove for engaging with the feed pipeline. The arc-shaped groove is located above the rectangular groove. The two locking blocks are locked together by a locking bolt. A slide rail is fitted inside the rectangular groove, and a collection tank for receiving liquid dripping from the outlet of the feed pipeline is slidably mounted on the slide rail. This device is used for conveying liquid sugar... A collection tank is installed below the outlet of the spice supply pipeline. The position of the collection tank and two locking blocks can be adjusted according to the specific site conditions. This utility model is easy to assemble and disassemble. The collection tank catches the liquid dripping from the outlet of the supply pipeline, preventing the liquid from dripping onto the workshop floor and making it difficult to clean. However, when this device is in use, it uses the collection tank to collect the dripping spices. The collected spices will come into direct contact with the external environment, which will cause spice contamination and make it unusable. This reduces the practicality of the device and cannot meet the needs of users. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an anti-drip connection structure, which aims to improve the problem of fragrance waste that occurs in the existing anti-drip connection structure.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a drip-proof connection structure, including a connecting pipe, the front end of which is connected to an elbow, the top of which is threadedly connected to a sleeve, a concave plate fixedly connected to the lower side of the front wall of the sleeve, a slider provided inside the concave plate, a support plate fixedly connected to the top of the slider, a connecting rod rotatably connected to the top of the support plate through the concave plate, a support frame fixedly connected to the top of the front side of the concave plate, a movable plate rotatably connected to the top of the support frame, a connecting seat fixedly connected to the rear side of the movable plate, the inner side of the connecting seat rotatably connected to the connecting rod, a baffle plate fixedly connected to the top of the movable plate, a pulling component provided at the bottom of the inner side of the concave plate, and a control mechanism provided at the top of the connecting pipe, the control mechanism being used to conveniently control the discharge speed of the device.

[0008] The control mechanism includes a hollow block, which is fixedly connected to the top of the connecting pipe. A hollow tube is rotatably connected to the inner top of the hollow block, and a rotating rod is rotatably connected to the inner top of the hollow block. The bottom end of the hollow tube passes through the hollow block and the connecting pipe in sequence and is fixedly connected to a first valve body. The bottom end of the rotating rod passes through the hollow tube and is fixedly connected to a second valve body. A rotating assembly is provided inside the hollow block.

[0009] By controlling the angle between the first valve body and the second valve body, the discharge speed of the device can be precisely adjusted, thus improving the ease of use of the device.

[0014] The rotating assembly includes a transmission rod, which is rotatably connected to the right side of the hollow block. The left end of the transmission rod passes through the hollow block and is fixedly connected to a driving bevel gear. Driven bevel gears are rotatably connected to the upper side of the outer wall of both the hollow tube and the rotating rod. The two driven bevel gears are respectively meshed with the upper and lower sides of the driving bevel gear.

[0015] Through the above technical solution, the two driven bevel gears can drive the hollow tube and the rotating rod to rotate relative to each other, thereby controlling the angle between the first valve body and the second valve body.

[0016] As a further description of the above technical solution:

[0017] A knob is fixedly connected to the right end of the transmission rod, and the inner dimensions of the first valve body and the second valve body are matched with the inner dimensions of the connecting pipe.

[0019] As a further description of the above technical solution:

[0020] The concave plate has a groove at its inner rear end, and the rear end of the slider is slidably connected to the groove.

[0021] With the above technical solution, the slider can slide inside the groove, and the movement of the slider can be controlled.

[0022] As a further description of the above technical solution:

[0023] A fixing rope is fixedly connected to the middle right side of the concave plate, and an insert plate is fixedly connected to the top of the fixing rope. The left end of the insert plate passes through the concave plate.

[0024] The above technical solution allows for the restriction of the slider's movement by inserting a plate, ensuring that the baffle plate remains in the open position at all times.

[0025] As a further description of the above technical solution:

[0026] A leak-proof gasket is provided on the top inner side of the elbow, and the size of the dirt baffle is larger than the size of the sleeve.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, because the elbow is set upward, the liquid raw material remaining inside the sleeve will not drip. Furthermore, the spring pulls the slide rod downward, and the slider will drive the support plate downward. The support plate drives the connecting seat to move through the connecting rod. The movable plate then drives the baffle plate to cover the top of the sleeve, which can prevent contaminants from entering the sleeve and prevent the liquid raw material from being contaminated. This improves the practicality of the device and can meet the needs of users.

[0030] 2. In this utility model, the transmission rod drives the active bevel gear to rotate. Since the two driven bevel gears mesh with the upper and lower sides of the active bevel gear respectively, the two driven bevel gears will drive the hollow tube and the rotating rod to rotate relative to each other. The hollow tube and the rotating rod will then drive the first valve body and the second valve body to rotate relative to each other. By controlling the size of the angle between the first valve body and the second valve body, the discharge speed of the device can be precisely adjusted, which improves the convenience of using the device.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 3One embodiment of this utility model provides a drip-proof connection structure, including a connecting pipe 1, with an elbow 3 connected to the front end of the connecting pipe 1. A sleeve 4 is threadedly connected to the top of the elbow 3. A concave plate 5 is fixedly connected to the lower side of the front wall of the sleeve 4. A slider 6 is provided inside the concave plate 5. A support plate 7 is fixedly connected to the top of the slider 6. A connecting rod 8 is rotatably connected to the top of the support plate 7, which passes through the concave plate 5. A support frame 9 is fixedly connected to the top of the front side of the concave plate 5. A movable plate 10 is rotatably connected to the top of the support frame 9. A connecting seat is fixedly connected to the rear side of the movable plate 10. 11. The inner side of the connecting seat 11 is rotatably connected to the connecting rod 8. The top of the movable plate 10 is fixedly connected to the baffle plate 12. The bottom of the inner side of the concave plate 5 is provided with a pulling component. The top of the connecting pipe 1 is provided with a control mechanism 2. The control mechanism 2 is used to conveniently control the discharge speed of the device. The pulling component includes a hollow column 13. The hollow column 13 is fixedly connected to the bottom of the inner side of the concave plate 5. The bottom of the inner side of the hollow column 13 is fixedly connected to a spring 14. The top of the spring 14 is fixedly connected to a slide rod 15. The top of the slide rod 15 is fixedly connected to the bottom of the slider 6.

[0040] Specifically, when using this device for material discharge, the outer corrugated pipe is connected to the sleeve 4 to perform the discharge operation. After the discharge is completed, because the elbow 3 is set upward, it can ensure that the liquid material inside the sleeve 4 will not drip. At the same time, the spring 14 will pull the slide rod 15 downward. As the slide rod 15 moves downward, the slider 6 will also drive the support plate 7 downward. During the movement of the support plate 7, the connecting rod 8 can pull the connecting seat 11 to move. When the connecting seat 11 moves, it will cause the movable plate 10 to rotate. During the rotation of the movable plate 10, it will drive the baffle plate 12 to cover the top of the sleeve 4. The baffle plate 12 can effectively prevent any contaminants from entering the sleeve 4, thereby ensuring that the material remaining in the sleeve 4 remains clean and is not contaminated by the outside, improving the practicality of the device and meeting the needs of users.

[0041] Reference Figure 1 , Figure 4 and Figure 5The control mechanism 2 includes a hollow block 201, which is fixedly connected to the top of the connecting pipe 1. A hollow pipe 202 is rotatably connected to the top inner side of the hollow block 201, and a rotating rod 203 is rotatably connected to the top inner side of the hollow block 201. The bottom end of the hollow pipe 202 passes through the hollow block 201 and the connecting pipe 1 in sequence and is fixedly connected to a first valve body 204. The bottom end of the rotating rod 203 passes through the hollow pipe 202 and is fixedly connected to a second valve body 205. A rotating assembly is provided inside the hollow block 201. The rotating assembly includes a transmission rod 206, which is rotatably connected to the right side of the hollow block 201. The left end of the transmission rod 206 passes through the hollow block 201 and is fixedly connected to a driving bevel gear 207. Driven bevel gears 208 are rotatably connected to the upper outer walls of both the hollow pipe 202 and the rotating rod 203. The two driven bevel gears 208 are respectively meshed with the upper and lower sides of the driving bevel gear 207.

[0042] Specifically, when the discharge speed of the device needs to be adjusted, the transmission rod 206 is rotated. When the transmission rod 206 rotates, it drives the active bevel gear 207 to rotate. Since the active bevel gear 207 has driven bevel gears 208 meshing on both sides, when the active bevel gear 207 starts to rotate, the two driven bevel gears 208 will also rotate, and drive the hollow tube 202 and the rotating rod 203 to rotate in opposite directions. When the hollow tube 202 and the rotating rod 203 rotate, they will drive the first valve body 204 and the second valve body 205 to rotate relative to each other. At this time, the first valve body 204 and the second valve body 205 will form an angle. By precisely controlling the size of the angle, the discharge speed of the device can be precisely adjusted, which improves the convenience of using the device.

[0043] Reference Figure 1 , Figure 3 and Figure 4 A knob 19 is fixedly connected to the right end of the transmission rod 206. The inner dimensions of the first valve body 204 and the second valve body 205 are matched with the inner dimensions of the connecting pipe 1. A groove 16 is provided at the rear end of the inner side of the concave plate 5, and the rear end of the slider 6 is slidably connected to the groove 16.

[0044] Specifically, the operator can easily rotate the transmission rod 206 using the knob 19. The inner dimensions of the first valve body 204 and the second valve body 205 are matched with the inner dimensions of the connecting pipe 1, so that the first valve body 204 and the second valve body 205 can seal the connecting pipe 1. The slider 6 can slide inside the slide groove 16, and the movement of the slider 6 can be controlled.

[0045] Reference Figure 1 , Figure 2 and Figure 3A fixing rope 17 is fixedly connected to the middle right side of the concave plate 5, and an insert plate 18 is fixedly connected to the top of the fixing rope 17. The left end of the insert plate 18 passes through the concave plate 5. A leak-proof gasket 20 is provided on the top inner side of the elbow 3. The size of the dirt baffle 12 is larger than the size of the sleeve 4.

[0046] Specifically, the movement of the slider 6 can be restricted by inserting the insert plate 18, so that the baffle plate 12 can always be in the open state, and the leak-proof gasket 20 is used to improve the sealing of the device. The size of the baffle plate 12 is larger than the size of the sleeve 4, so that the baffle plate 12 can completely seal the sleeve 4.

[0047] Working principle: When using this device to discharge material, connect the outer corrugated pipe to the sleeve 4 to start the discharge operation. When the discharge is completed, because the elbow 3 is set upward, the liquid material inside the sleeve 4 will not drip. The spring 14 will pull the slide rod 15 downward, and the slider 6 will drive the support plate 7 downward. The support plate 7 will then drive the connecting seat 11 to move through the connecting rod 8. When the connecting seat 11 moves, it will drive the movable plate 10 to rotate. When the movable plate 10 rotates, it will drive the baffle plate 12 to cover the top of the sleeve 4, which can prevent contaminants from entering the sleeve 4 and prevent the material remaining in the sleeve 4 from being contaminated.

[0048] Furthermore, when the discharge speed of the device needs to be adjusted, rotating the transmission rod 206 will drive the driving bevel gear 207 to rotate. Since the two driven bevel gears 208 mesh with the driving bevel gear 207 on the upper and lower sides respectively, when the driving bevel gear 207 rotates, the two driven bevel gears 208 will drive the hollow tube 202 and the rotating rod 203 to rotate respectively. The hollow tube 202 and the rotating rod 203 will rotate relative to each other, and the hollow tube 202 and the rotating rod 203 will drive the first valve body 204 and the second valve body 205 to rotate respectively. At this time, the first valve body 204 and the second valve body 205 will form a certain angle. By controlling the size of the angle between the first valve body 204 and the second valve body 205, the discharge speed of the device can be precisely adjusted.

[0049] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
