Description

Technical Field

[0001] This utility model relates to the field of air pressure testing technology, and in particular to a low-cost and convenient silicone tube adapter for balloons. Background Technology

[0002] In high school physics experiments, some digital experiments require measuring the air pressure of balloons, such as the nail-board experiment. However, connecting various balloons, after fully inflating them, to the air pressure sensor is a very cumbersome task in practice.

[0003] The existing method of connecting a balloon to a pressure sensor involves pinching the balloon's nozzle with your fingers, carefully inserting its silicone tube into the nozzle, and then quickly tying the nozzle to the outside of the silicone tube with a thin thread. This operation is time-consuming, and tying the thread usually requires two hands. If only one person is operating the device, releasing the nozzle may cause air leakage, leading to the failure of the entire operation and requiring a restart. Therefore, it is necessary to improve the design of a new, low-cost, and convenient balloon silicone tube adapter to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to improve a low-cost and convenient silicone tube adapter for balloons, so as to overcome the above-mentioned shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a low-cost and convenient balloon silicone tube adapter, comprising: a connecting shell, a tower-type connecting port fixedly connected to the left side of the connecting shell, a silicone tube insertion port fixedly connected to the right side of the tower-type connecting port, a Luer head pre-slot installed in the inner cavity of the silicone tube insertion port, and a venting tube installed between the connecting shell, the tower-type connecting port and the silicone tube insertion port.

[0006] The device features a rotary valve, with a valve ball mounted on the upper right side of the connecting housing. The valve ball is installed at the bottom of the rotary valve and is attached to the air inlet pipe. A fixing rod is mounted at the bottom of the connecting housing, with a collar fixedly connected to the bottom left side of the fixing rod. A clamping mechanism is installed in the middle of the collar. A tower-type connection port accommodates various commonly used balloon models, allowing for easy insertion and sealing of the balloon's nozzle. A silicone tube insertion port facilitates the insertion of silicone tubes, providing a certain degree of sealing. The rotary valve and valve ball allow for manual control of the valve's opening and closing. The clamping mechanism ensures effective clamping and fixation, preventing the balloon's air inlet from detaching during use.

[0007] As a further description of the above technical solution: the clamping mechanism includes a bidirectional screw rotatably connected to the middle of the collar, a throttle fixedly connected to the bottom of the bidirectional screw, a fixing ring sleeved on the upper end of the bidirectional screw, and arc-shaped rods fixedly connected to the left and right sides of the fixing ring. A sleeve mechanism is installed on the upper end of the arc-shaped rods. By providing the bidirectional screw, it is convenient to drive the device for adjustment. By providing the fixing ring, it is convenient to drive the first clamping sleeve for up and down adjustment.

[0008] As a further description of the above technical solution: the sleeve mechanism includes a first clamping sleeve fixedly connected to the top of the arc-shaped rod, and a second clamping sleeve sleeved at the upper end of the arc-shaped rod. Springs are installed on the inner walls of the first and second clamping sleeves, and clamping blocks are installed on the sides of the springs close to each other. A fixing groove is fixedly connected to the bottom center of the second clamping sleeve. By rotating the bidirectional screw, the fixing ring moves backward, thereby driving the first clamping sleeve to clamp backward. Simultaneously, the bidirectional screw rotates, driving the fixing groove forward, causing the second clamping sleeve to move forward and clamp, ensuring that the device can clamp in the center. The springs and clamping blocks facilitate elastic clamping of the balloon inlet sleeved on the tower-type connection port, preventing damage to the balloon inlet and tower-type connection port during clamping, improving the safety of the device, ensuring the effectiveness of the clamping and fixing, and preventing the balloon inlet from falling off during use.

[0009] As a further description of the above technical solution: the upper outer surface of the bidirectional screw is connected with a thread, and the fixing ring and fixing groove are provided with threaded grooves that are adapted to the thread. The bidirectional screw, the fixing ring and the fixing groove form a rotating connection mechanism. By forming a rotating connection mechanism with the fixing ring and the fixing groove, it is convenient for the bidirectional screw to rotate and drive the fixing ring and the fixing groove to move in different directions.

[0010] As a further description of the above technical solution: the second clamping sleeve is slidably mounted on the arc-shaped rod, so that the fixing groove can push the second clamping sleeve for clamping.

[0011] As a further description of the above technical solution: A silicone ring is installed on the right side of the inner cavity of the vent tube, and the silicone ring can be easily inserted with a little force, and has a certain degree of sealing after insertion. Usually, after the silicone tube is inserted, it will slowly leak air in most cases. By setting the silicone ring, it is easy to reduce the leakage error caused by the experiment, which has practical value.

[0012] As a further description of the above technical solution: the top of the fixed rod is connected to a slider, and the connecting shell has a groove adapted to the slider. The fixed rod and the connecting shell form a sliding connection mechanism. By forming a sliding connection mechanism, the clamping mechanism can be easily adjusted back and forth, and can be adjusted according to the air inlet position of different balloons, making it convenient to clamp and use balloons of different sizes.

[0013] This invention provides a low-cost and convenient silicone tube adapter for balloons. It offers the following advantages:

[0014] 1. With a silicone tube insertion port, a knob-type air valve, and a silicone ring, the device can quickly and easily connect an inflated balloon to a silicone tube, allowing the balloon to be smoothly connected to the pressure sensor. There is very little air leakage during the connection process. If a standard Luer head is used, there will be almost no air leakage. The internal air pressure of the balloon will not change much during the experiment, which improves the accuracy of subsequent experiments.

[0015] 2. By incorporating a clamping mechanism, rotating the bidirectional screw moves the fixing ring backward, thereby causing the first clamping sleeve to clamp backward. Simultaneously, the rotation of the bidirectional screw moves the fixing groove forward, causing the second clamping sleeve to move forward and clamp, ensuring that the device can clamp in the center. The inclusion of springs and clamping blocks facilitates the elastic clamping of the balloon inlet fitted onto the tower-type connector, preventing damage to the balloon inlet and the tower-type connector during clamping. This improves the safety of the device and ensures the effectiveness of the clamping and fixing, preventing the balloon inlet from falling off during use. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1, Reference Figure 1 , Figure 2 and Figure 3 This utility model discloses a low-cost and convenient balloon silicone tube adapter, which can solve the problems of cumbersome operation during the connection of balloons to air pressure sensors and easy leakage and error during use. It includes a connecting shell 1, a tower-type connecting port 2 fixedly connected to the left side of the connecting shell 1, a silicone tube insertion port 3 fixedly connected to the right side of the tower-type connecting port 2, a Luer female head preparation groove 4 installed in the inner cavity of the silicone tube insertion port 3, and a venting tube 5 installed between the connecting shell 1, the tower-type connecting port 2 and the silicone tube insertion port 3.

[0025] A rotary valve 6 is installed on the upper right side of the connecting housing 1. A valve ball 7 is installed at the bottom of the rotary valve 6 and is installed on the air pipe 5. A fixing rod 9 is installed at the bottom of the connecting housing 1. A collar 10 is fixedly connected to the bottom left side of the fixing rod 9. A clamping mechanism 11 is installed in the middle of the collar 10.

[0026] Working principle: The outer shell 1 facilitates the installation and use of components; the tower-type connection port 2 adapts to various common balloon models, allowing the balloon's nozzle to be easily inserted into one layer with a good seal; the silicone tube insertion port 3 facilitates the insertion of silicone tubes, providing a certain degree of sealing after insertion; the Luer female head pre-slot 4 allows the Luer female head to be directly embedded into the pre-slot 4 and sealed with adhesive, thus enabling it to mate with the Luer male head, achieving a connection with almost no air leakage and improving experimental accuracy; the vent pipe 5 facilitates the inflation of the balloon's interior; the knob-operated air valve 6 and air valve ball 7 allow gas flow throughout the component when the through hole and vent pipe 5 are in the same direction, and when they are in opposite directions, gas flow is blocked; the fixing rod 9 and collar 10 facilitate the installation and use of the clamping mechanism 11. The clamping mechanism 11 ensures the effectiveness of the device's clamping and fixing, preventing the balloon's air inlet from falling off during use.

[0027] Example 2, refer to Figure 3 , Figure 4 and Figure 5 This embodiment solves the problems of cumbersome operation and easy leakage during use of existing balloon-to-pressure sensor connections. The new low-cost and convenient balloon silicone tube adapter further includes a clamping mechanism 11 comprising a bidirectional screw 111 rotatably connected to the center of a collar 10. A handle 112 is fixedly connected to the bottom of the bidirectional screw 111. A fixing ring 113 is sleeved on the upper end of the bidirectional screw 111. Arc-shaped rods 114 are fixedly connected to the left and right sides of the fixing ring 113. A sleeve mechanism 115 is installed on the upper end of the arc-shaped rods 114. The sleeve mechanism 115 includes a first clamping sleeve 1151 fixedly connected to the top of the arc-shaped rods 114, and a second clamping sleeve 1152 sleeved on the upper end of the arc-shaped rods 114. The first clamping sleeve 1151 and the second clamping sleeve 1152... Spring 1153 is installed on the inner wall of 52. Clamping block 1154 is installed on one side of spring 1153 close to each other. Fixing groove 1155 is fixedly connected to the bottom middle of the second clamping sleeve 1152. The upper outer surface of the bidirectional screw 111 is connected with threads. The fixing ring 113 and the fixing groove 1155 are provided with threaded grooves that are compatible with the threads. The bidirectional screw 111, the fixing ring 113 and the fixing groove 1155 form a rotating connection mechanism. The second clamping sleeve 1152 is slidably installed on the arc-shaped rod 114. A silicone ring 8 is installed on the right side of the inner cavity of the vent pipe 5. The silicone ring 8 can be easily inserted with a little force and has a certain sealing performance after insertion. A slider is connected to the top of the fixing rod 9. The connecting shell 1 is provided with a sliding groove that is compatible with the slider. The fixing rod 9 and the connecting shell 1 form a sliding connection mechanism.

[0028] Working Principle: When using this device, after inserting the balloon inlet into the tower-type connector 2, adjust the fixing rod 9 to a suitable position so that the clamping mechanism 11 corresponds to the balloon inlet. By rotating the bidirectional screw 111, the fixing ring 113 moves backward, thereby driving the first clamping sleeve 1151 to clamp backward. Simultaneously, the rotation of the bidirectional screw 111 drives the fixing groove 1155 forward, causing the second clamping sleeve 1152 to move forward and clamp, ensuring that the device can clamp in the center. The inclusion of a spring 1153 and a clamping block 1154 facilitates the elastic clamping of the balloon inlet fitted onto the tower-type connector 2. The clamping mechanism prevents damage to the balloon's air inlet and tower-type connection port 2 during clamping, improving the safety of the device and ensuring its effective clamping and fixing. It also prevents the balloon's air inlet from detaching during use. After clamping, open the knob-operated air valve 6 and blow air into the balloon to the desired size through the silicone tube insertion port 3. Then close the knob-operated air valve 6, connect the silicone tube to one end of the relative pressure sensor, and insert the other end of the silicone tube into the ventilation tube 5 for easy balloon pressure detection. If using a Luer connector adapter, simply screw the male connector from the pressure sensor into the female connector of the balloon ventilation adapter.
