Description

Technical Field

[0001] This utility model relates to the field of filling head technology, specifically to a drip-proof ammonia filling head structure. Background Technology

[0002] Ammonia water is an aqueous solution of gaseous ammonia, with a primary component being ammonia monohydrate. It is colorless, transparent, and has a pungent odor. Ammonia water is less dense than water, unstable, volatile, and easily decomposes upon exposure to light and heat. Ammonia water itself is a non-flammable and non-explosive liquid. However, the ammonia gas separated from the water has a strong, pungent odor and is irritating and corrosive to the eyes, nose, and skin, and also poses a risk of combustion and explosion.

[0003] Chinese utility model patent with authorization announcement number CN202222753392.1 discloses an anti-drip filling head that utilizes a docking and guiding mechanism. During use, as the main body moves, the hemispherical sleeve first contacts the opening of the container. After contact, the inner wall of the hemispherical sleeve guides the opening of the container to align with the filling tube, so that the filling tube can accommodate a certain degree of deviation in the position of the container, thereby preventing dripping. It is also equipped with a dustproof component that can flip the fan-shaped plate to close the hemispherical sleeve to protect the filling tube from dust when not filling. During filling, the container will push open the fan-shaped plate to facilitate filling with the filling tube.

[0004] However, in traditional filling head structures, the height adjustment of the sliding sleeve usually relies on screws for locking and fixing. During operation, wrenches or other tools are needed to tighten or loosen the screws one by one. This is not only cumbersome and time-consuming, but also requires a certain level of technical proficiency from the operators, making it difficult to meet the actual needs of modern automated, high-speed production lines for rapid switching and efficient operation. On the other hand, during frequent height adjustments, the screws and screw holes experience mechanical wear due to repeated tightening, which can easily lead to loose connections, positioning deviations, and other problems. This can affect the stability and repeatability of the sliding sleeve, and after long-term use, it may even cause parts to jam or fail to lock effectively, thereby reducing the service life and operational reliability of the equipment.

[0005] Therefore, we propose a drip-proof ammonia filling head structure. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a drip-proof ammonia filling head structure, which can effectively solve the problems in the background technology.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a drip-proof ammonia filling head structure, comprising a filling head for discharging ammonia, a sliding sleeve provided on the filling head, a dust-proof component provided on the sliding sleeve, limiting components fixedly connected to both ends of the filling head respectively, and the two limiting components facing opposite directions, and an adjusting member provided on the sliding sleeve, the adjusting member being used to adjust the vertical position of the sliding sleeve on the limiting component.

[0008] Furthermore, the limiting component includes a fixing plate, which is fixedly connected to the outer wall of the filling head, and a plurality of equidistant triangular fixing blocks are fixedly connected to the end of the fixing plate away from the filling head.

[0009] Furthermore, the fixed plate has two sliding grooves for the vertical sliding of the adjusting component.

[0010] Furthermore, the adjusting component includes two sliding blocks, the outer walls of the two sliding blocks are slidably connected to the inner wall of the sliding ladder groove, a positioning component is provided between the two sliding blocks, and a protective connecting plate is fixedly connected to the end of the two sliding blocks away from the sliding ladder groove, the bottom of the protective connecting plate is fixedly connected to the sliding sleeve.

[0011] Furthermore, the positioning component includes a positioning rod, the two ends of which are rotatably connected to two sliding blocks. A positioning tooth is fixedly connected to the positioning rod, and a torsion spring is fixedly connected to the two ends of the positioning tooth and the adjacent ends of the two sliding blocks. The torsion spring is used to move and reset the positioning tooth.

[0012] Furthermore, a push plate is fixedly connected to the outer wall of the positioning tooth.

[0013] Compared with the prior art, this utility model provides a drip-proof ammonia filling head structure, which has the following beneficial effects:

[0014] This anti-drip ammonia filling head structure, through the above design, allows the sliding sleeve to achieve rapid lifting and lowering adjustment without the use of any tools. Moreover, whether lifting or lowering, continuous locking can be achieved through the cooperation of the positioning teeth on both sides and the triangular fixing blocks, effectively adapting to the height requirements of filling containers of different sizes.

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model readily understandable, the present utility model will be further described below with reference to the accompanying drawings of the 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.

[0021] To address the shortcomings of existing technologies, such as Figures 1-4 As shown, this utility model provides a drip-proof ammonia filling head 1 structure, including a filling head 1 for discharging ammonia, a sliding sleeve 2 on the filling head 1, a dust-proof component on the sliding sleeve 2, and limiting components fixedly connected to both ends of the filling head 1, with the two limiting components facing opposite directions. An adjusting component is provided on the sliding sleeve 2, which is used to adjust the vertical position of the sliding sleeve 2 on the limiting component.

[0022] By using limit components and adjustment parts, the traditional screw locking mechanism can be replaced for rapid adjustment, adapting to high-speed production lines and reducing manual intervention time.

[0023] The dustproof component can be found in a drip-proof filling head 1 disclosed in patent number CN202222753392.1, which aims to prevent residual ammonia from dripping from the filling head 1.

[0024] The limiting component includes a fixing plate 3, which is fixedly connected to the outer wall of the filling head 1. A plurality of equidistant triangular fixing blocks 5 are fixedly connected to the end of the fixing plate 3 away from the filling head 1. Two sliding ladder grooves 4 for vertical sliding of the adjusting component are provided on the fixing plate 3.

[0025] The adjusting component includes two sliding blocks 6, the outer walls of the two sliding blocks 6 are slidably connected to the inner wall of the sliding ladder groove 4, a positioning component is provided between the two sliding blocks 6, a protective connecting plate 7 is fixedly connected to the end of the two sliding blocks 6 away from the sliding ladder groove 4, the bottom of the protective connecting plate 7 is fixedly connected to the sliding sleeve 2, the positioning component includes a positioning rod 8, the two ends of the positioning rod 8 are rotatably connected to the two sliding blocks 6, a positioning tooth 9 is fixedly connected to the positioning rod 8, and a torsion spring 10 is fixedly connected to the two ends of the positioning tooth 9 and the adjacent ends of the two sliding blocks 6. The torsion spring 10 is used to move and reset the positioning tooth 9, and a push plate 11 is fixedly connected to the outer wall of the positioning tooth 9.

[0026] It should be noted that, as Figure 3 As shown in Figure 4, the multiple triangular fixing blocks 5 on the two limiting components face opposite directions, and the positioning teeth 9 of the two positioning rods 8 face opposite directions, so that the vertical height can be adjusted by opening the positioning part on the corresponding side when rising or falling.

[0027] It is worth noting that after the positioning teeth 9 on both sides are positioned on the adjacent triangular blocks, a certain space can be maintained between the positioning teeth 9 and the triangular blocks to avoid interference between the two positioning teeth 9 and ensure smooth switching. This avoids the problem of not being able to rotate due to the small distance between the two positioning teeth 9 after they are positioned at the same time.

[0028] The working principle is as follows: When the vertical position of the sliding sleeve 2 needs to be adjusted, an inward pressing force is first applied to one of the push plates 11. This force causes the positioning tooth 9 to rotate around the positioning rod 8 connected to it, and further drives the internal structure of the sliding block 6 to move. At the same time, a torsional torque is applied to the torsion springs 10 nested at both ends of the positioning rod 8, so that they are in a compressed and energy-storing state. As the rotation angle of the positioning tooth 9 changes, the positioning tooth 9 that was originally engaged between its two adjacent triangular fixing blocks 5 gradually disengages, thereby releasing the locking state in the current height direction. At this time, the sliding sleeve 2 can move freely up or down along the outer wall of the filling head 1. During the sliding process, the positioning tooth 9 on the other side that is not pressed is always kept in close contact with the surface of the triangular fixing block 5 on the corresponding limiting component due to the restoring elastic force provided by the torsion spring 10. When the sliding sleeve 2 moves to a new position, the triangular fixing block 5 will push the positioning tooth 9 on that side to rotate slightly so as to smoothly pass over the top structure of the current triangular block. Once the positioning tooth 9 passes over a triangular block and enters the next gap area, the torsion spring 10 immediately releases its elastic potential energy, driving the positioning tooth 9 to quickly reset and re-engage with the two adjacent triangular fixing blocks 5, thereby achieving temporary height positioning. This process is repeated, and the sliding sleeve 2 can slide smoothly between multiple stepped height levels formed by the triangular fixing blocks 5. When the sliding sleeve 2 is adjusted to the target height, simply release the pressure previously applied to the positioning tooth 9, and the torsion spring 10, which was originally deformed by the force, will immediately return to its initial state, causing the positioning tooth 9 on that side to automatically spring back and re-engage between the two adjacent triangular fixing blocks 5, completing the final height locking.

[0029] Through the above design, the sliding sleeve can achieve rapid one-handed lifting and lowering adjustment without the need for any tools. Furthermore, regardless of whether it is rising or falling, continuous locking is achieved through the cooperation of the positioning teeth on both sides and the triangular fixing blocks, effectively adapting to the height requirements of different sized filling containers. This structure not only avoids the cumbersome operation, time-consuming and labor-intensive problems caused by traditional screw locking methods, but also greatly improves the adaptability and response speed of the equipment in high-speed production lines, demonstrating excellent engineering application prospects.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
