Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, specifically a three-way fixing box. Background Technology

[0002] Medical three-way valves have three openings: one inlet and two outlets, or two inlets and one outlet. They come in T-type and Y-type appearances and have both equal-diameter and different-diameter inlets. Medical three-way valves are mostly used for intravenous infusion in clinical work. Three-way valves used in intravenous infusion usually require multiple connections in order to change the type of infusion.

[0003] Traditional tee connections typically employ simple pipe fittings and are secured with tape or clamps. However, under complex operating conditions, such as high temperature, high pressure, strong vibration, or long-term fluid impact, these connections are prone to loosening and leakage, severely affecting the stability and reliability of the pipeline system and increasing maintenance costs and safety risks. To address these issues, we provide a tee fixing box. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a three-way fixing box.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a three-way fixing box, including a box base, a box cover hinged to one side of the box base, a limiting groove 1 formed on the upper surface of the box base, a limiting groove 2 formed on the bottom surface of the box cover, a three-way body placed inside the limiting groove 1, a set of slots formed on the outer surface of the box base, an accidental contact box fixedly connected to the upper surface of the box cover, a pressing mechanism provided inside the accidental contact box, and a set of fixing mechanisms provided outside the box cover.

[0006] Preferably, the clamping mechanism includes an adjusting screw threaded to the inner wall of the box cover, and the adjusting screw extends through to the inner side of the limiting groove two, with a knob fixedly connected to one end of the adjusting screw.

[0007] Preferably, the other end of the adjusting screw is fixedly connected to a limiting disc, the outer surface of the limiting disc is rotatably connected to a pressure plate, and the outer surface of the pressure plate is fixedly connected to an elastic pad.

[0008] Preferably, the fixing mechanism includes an L-shaped frame fixedly connected to the outer surface of the box cover, and an insert rod is slidably connected to the inner wall of the L-shaped frame, and the insert rod is inserted into the inside of the slot.

[0009] Preferably, a pull ring is fixedly connected to the outer surface of the insertion rod, and a baffle is fixedly connected to the outer surface of the insertion rod.

[0010] Preferably, an elastic element is sleeved on the outer surface of the insertion rod, one end of the elastic element is fixedly connected to the outer surface of the L-shaped frame, and the other end of the elastic element is fixedly connected to the outer surface of the baffle.

[0011] Beneficial effects:

[0012] Compared with existing technologies, this tee fixing box has the following advantages:

[0013] I. This utility model, by setting a limiting groove 1, a limiting groove 2, a fixing mechanism, and a slot, can achieve the initial limiting effect on the tee body. By setting a pressing mechanism, it can achieve the pressing and fixing effect on the tee body. Through the cooperation of the limiting groove 1, the limiting groove 2, the fixing mechanism, the slot, and the pressing mechanism, a stable fixing effect on the tee body can be achieved, thereby avoiding loosening and leakage of the tee body, ensuring the stability and reliability of the pipeline system, and reducing maintenance costs and safety risks.

[0014] Second, by pulling the pull ring outward, this utility model can drive the insert rod and the baffle to move. At the same time, the insert rod can compress the elastic element to overcome its elastic potential energy, so that the insert rod can quickly move out of the slot and release the fixed limit between the box seat and the box cover, thereby facilitating the disassembly and replacement of the T-shaped body and making it convenient to use.

Detailed Implementation

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] See Figures 1-5 A three-way fixed box includes a box base 1. The main body of the box base 1 is integrally injection molded from high-strength engineering plastic. A box cover 2 is hinged to one side of the box base 1 via a precision hinge shaft. The material of the box cover 2 matches that of the box base 1. This hinge design ensures that the box cover 2 can open and close flexibly and fits tightly against the box base 1, effectively preventing foreign objects from entering.

[0023] The upper surface of the box base 1 is precisely provided with a limiting groove 3, the shape of which is a custom-made arc-shaped groove based on the shape of the tee body 5. The groove has a moderate depth and can accurately accommodate and position the bottom of the tee body 5. The bottom surface of the box cover 2 is correspondingly provided with a limiting groove 4. When the two are in contact, the gap is extremely small, which can restrict the horizontal displacement of the tee body 5 in all directions, avoid the tee body 5 from shifting due to external force or fluid impact, ensure the coaxiality of the connecting pipe, and maintain the smooth and stable operation of the infusion system.

[0024] The limiting groove 3 contains a three-way body 5, which can be made of medical-grade stainless steel with a smooth surface and excellent corrosion resistance, ensuring safety and hygiene during long-term use.

[0025] A set of slots 6 are evenly distributed on the outer surface of the box base 1. The inner wall of the slots 6 is frosted, with moderate friction, which facilitates the insertion and fixation of the subsequent insertion rod 902, while preventing accidental loosening.

[0026] The upper surface of the cover 2 is fixedly connected to the accidental contact box 7. The accidental contact box 7 adopts a semi-enclosed design and is made of transparent polycarbonate material. It protects the internal mechanism and facilitates observation and operation, providing reliable protection and operating space for the clamping mechanism 8, and avoiding damage to the mechanism or interference with the fixing effect of the tee body 5 due to accidental operation.

[0027] The inside of the accidental contact box 7 is equipped with a clamping mechanism 8.

[0028] The adjusting screw 801 in the clamping mechanism 8, which is threaded to the inner wall of the cover 2, is made of high-strength alloy material and has fine threads on its surface to ensure smooth and accurate rotation adjustment and strong load-bearing capacity. It extends through the inner side of the limiting groove 4 and is fixedly connected to a knob 802 at one end. The knob 802 has a knurled surface to increase friction and facilitate hand-held rotation operation.

[0029] The other end of the adjusting screw 801 is fixedly connected to a limiting disc 803. The diameter of the limiting disc 803 is slightly larger than the diameter of the screw, which limits the maximum displacement of the pressure plate 804 and prevents excessive compression from damaging the tee body 5.

[0030] The outer surface of the limiting disc 803 is rotatably connected to the pressure plate 804 via a low-friction bushing. The pressure plate 804 is made of hard aluminum alloy and is arc-shaped and flat. Its bottom surface is tightly bonded to the elastic pad 805 to ensure that the pressure is evenly transmitted to the tee body 5. The elastic pad 805 is made of medical-grade silicone, which is soft and has good resilience. It can adapt to the shape of the tee body 5 and fill the tiny gaps. While ensuring firm fixation, it avoids rigid contact damage to the pipe surface and improves the overall fixation reliability and stability.

[0031] A set of fixing mechanisms 9 is provided on the outside of the box cover 2.

[0032] The fixing mechanism 9 includes an L-shaped frame 901 fixedly connected to the outer surface of the cover 2. The L-shaped frame 901 is formed by bending stainless steel, which has a stable structure. Its inner wall is polished and slides smoothly with the insertion rod 902 without jamming, providing precise linear guidance for the insertion rod 902.

[0033] The inner wall of the L-shaped frame 901 is slidably connected to the insertion rod 902. The insertion rod 902 is a solid stainless steel rod with rounded ends. When inserted into the slot 6, it is smooth and avoids scratching the inner wall of the slot 6. It is inserted into the slot 6 and fits tightly with the slot 6. It bears and disperses the stress at the connection between the box cover 2 and the box base 1, ensuring the overall structure is stable and resisting external impact and vibration interference.

[0034] A pull ring 903 is fixedly connected to the outer surface of the insertion rod 902. The pull ring 903 is made of plastic and is ergonomically designed to facilitate finger pulling.

[0035] A baffle 904 is also fixedly connected to the outer surface of the insertion rod 902. The baffle 904 is of moderate size and limits the maximum pull-out displacement of the insertion rod 902 to prevent loss.

[0036] An elastic element 905 is fitted on the outer surface of the insertion rod 902. The elastic element 905 is a helical spring with an elastic coefficient selected through multiple tests and optimizations. One end is reliably welded and fixed to the outer surface of the L-shaped frame 901, and the other end is firmly connected to the outer surface of the baffle 904. Under normal conditions, it maintains the pre-tight force of the insertion rod 902 in the slot 6, ensuring a tight connection between the box cover 2 and the box base 1. When unlocking, it provides a stable reset force, making the fixing mechanism 9 easy and efficient to operate, enhancing the convenience and maintainability of the three-way fixing box, and effectively ensuring the efficient and safe operation of the infusion system.

[0037] Working principle: When using this utility model, first place the T-shaped body 5 in the limiting groove 3 of the box base 1, and cover it with the box cover 2. At this time, the limiting groove 4 on the box cover 2 cooperates with the limiting groove 3 to initially limit the T-shaped body 5. The insert rod 902 in the fixing mechanism 9 is inserted into the slot 6 on the outer surface of the box base 1. The elastic element 905 is in a natural state or a slightly compressed state to ensure that the box cover 2 and the box base 1 are tightly connected and prevent loosening. When it is necessary to press the T-shaped body 5, turn the knob 802 of the pressing mechanism 8 to drive the adjusting screw 801 to rotate. Because the adjusting screw 801 is threaded to the inner wall of the box cover 2 and passes through to the inner side of the limiting groove 4, the pressure plate 804 and the elastic pad 805 at one end move closer to the T-shaped body 5 with the screw. 5. Tightly fit the surface of the tee body 5. Adjust the clamping force precisely according to the rotation direction and amplitude of the knob 802 to firmly fix the tee body 5 in the box, avoiding displacement and loosening that could lead to leakage. When disassembling or replacing the tee body 5, pull the pull ring 903 of the fixing mechanism 9 outward. The insert rod 902 and the baffle 904 move with the pull ring 903. The insert rod 902 moves out of the slot 6. During this process, the insert rod 902 compresses the elastic element 905 to overcome its elastic potential energy, releasing the fixing limit between the box cover 2 and the box seat 1. The tee body 5 can then be easily operated. After the replacement is completed, release the pull ring 903. The elastic element 905 releases its potential energy, causing the insert rod 902 to reset and restore its fixing function. This ensures the stable and reliable operation of the pipeline system, reduces maintenance and safety risks, and is simple and efficient to operate.

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.
