Description

Technical Field

[0001] The utility model belongs to the technical field of rubber sealing balloons, in particular to a rubber sealing balloon. Background Art

[0002] Rubber sealing balloons are made of rubber and are commonly used in various occasions that require sealing and maintaining air pressure. This type of balloon is usually made of natural rubber or synthetic rubber, has excellent elasticity and durability, and can withstand greater pressure and temperature.

[0003] For example, a Chinese patent with publication number CN203139625U discloses a sealed balloon, including a balloon body, wherein an air inlet is arranged at the top of the balloon body, and a rubber block is arranged at the air inlet. The utility model has a simple structure and is easy to use. When inflating, the needle of the vacuum inflator can be inserted into the rubber block at the air inlet of the balloon. It can be inflated without tying, and has good market promotion value.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: the air inlet of the balloon is not well sealed, which may cause the gas in the balloon to leak continuously. If the air inlet of the balloon is not well sealed, the balloon will gradually become smaller or even leak completely, affecting the aesthetics of the balloon and making it unsalable. In view of this, we propose a rubber sealed balloon. Utility Model Content

[0006] The purpose of the utility model is to provide a rubber sealing balloon to solve the problems raised in the above background technology.

[0007] In view of this, the utility model provides a rubber sealing balloon, comprising:

[0008] A balloon, wherein a cylindrical tube is tightly bonded to the air inlet of the balloon, an air inlet hole and a rotation groove are opened on the top of the cylindrical tube, and the rotation groove is located in the air inlet hole;

[0009] A disc, wherein the disc is fixedly installed in a cylindrical tube, a plurality of ventilation holes are opened on the disc, and a through hole is opened in the middle of the disc, a sliding column is slidably installed in the through hole, a lever is rotatably installed at the lower end of the sliding column and located at the bottom of the disc, a sealing disc plugged with the air inlet hole is fixedly installed on the top of the sliding column, and a limiting disc is fixedly installed on the top of the sealing disc, and a spring is sleeved on the outside of the sliding column and located between the sealing disc and the disc.

[0010] In the technical solution, when the balloon needs to be inflated, the bottom of the lever is rotated 90° upward on the sliding column, and the spring rebounds and pushes the sealing disk out of the air inlet. The sealing disk drives the sliding column and the lever to move upward until the lever is parallel to the disk, and one side of the lever is tightly fitted with the bottom of the disk. At the same time, the air inlet is connected to the inner cavity of the balloon. Then, the person blows air into the cylinder. The gas first enters the cylinder through a number of vents and enters the balloon through the air inlet, which makes it convenient to blow the balloon. The air inlet of the balloon is highly sealed to ensure that the gas will not leak from the air inlet to the outside. At the same time, it can be recycled.

[0011] When the balloon is blown up and needs to be taken away, the staff first pinches the connection between the balloon's air inlet and the cylindrical tube, then pulls the pull rope and drives the bottom of the lever to rotate downward 90° on the sliding column to restore it to its original position. The lever will drive the sliding column to move downward, and the sliding column will drive the sealing disk into the air inlet. The bottom of the limit disk fits tightly with the bottom of the rotating groove to ensure the sealing of the balloon's air inlet. At the same time, the spring is squeezed and contracted, and the spring pulls the lever so that it will not move around when not in use, thereby enhancing the stability of the device's operation and preventing gas from leaking from the balloon. Under the action of the thread, the support column and the cylindrical tube are threadedly connected to facilitate carrying the blown balloon.

[0012] In the above technical solution, further, the plurality of ventilation holes are distributed in a circular shape with equal intervals, the cross-section of the lever is a U-shaped structure, and the top of the lever is an arc structure, and a pull rope is tightly bonded to the bottom of the lever.

[0013] In this technical solution, it is ensured that the gas can pass through the vent hole evenly, and the bottom of the lever can be rotated 90° upward on the sliding column. Pulling the pull rope can drive the bottom of the lever to rotate 90° downward on the sliding column and reset.

[0014] In the above technical solution, further, a rubber ring is fixedly installed on the side wall of the sealing disk and located in the air inlet hole, and the two ends of the spring are tightly welded to the top of the disk and the bottom of the sealing disk respectively.

[0015] In the technical solution, the spring can push the sealing disk to separate from the air inlet; under the action of the rubber pad, the air inlet of the balloon can be sealed.

[0016] In the above technical solution, further, the bottom of the limiting plate is located in the rotation groove, and the limiting plate is plugged into and matched with the rotation groove, and a rubber pad is fixedly installed on the bottom of the limiting plate.

[0017] In this technical solution, after the limiting plate enters the rotating groove, the air inlet of the balloon can be further sealed under the action of the rubber pad.

[0018] In the above technical solution, further, a support column is threadedly connected inside the cylindrical tube and located at the bottom of the disc.

[0019] In this technical solution, when the balloon needs to be taken away after being blown up, the support column and the cylindrical tube are threadedly connected under the action of the thread, so that the blown balloon is convenient to carry.

[0020] The beneficial effects of the utility model are:

[0021] When the rubber sealed balloon needs to be inflated, the bottom of the lever is rotated 90 degrees upward on the sliding column, and the spring rebounds and pushes the sealing disk out of the air inlet. The sealing disk drives the sliding column and the lever to move upward until one side of the lever is tightly fitted with the bottom of the disc, and the air inlet is connected with the inner cavity of the balloon. Then, a person blows air into the cylinder, and the gas first enters the cylinder through a plurality of vents and then enters the balloon through the air inlet, so as to facilitate the balloon blowing. The balloon has a strong sealing performance on the air inlet, ensuring that the gas will not leak from the air inlet to the outside, and the balloon can be repeatedly used.

[0022] When the balloon is blown up and needs to be taken away, the staff first pinches the connection between the balloon's air inlet and the cylindrical tube, then pulls the pull rope and drives the bottom of the lever to rotate downward 90° on the sliding column to restore it to its original position. The lever will drive the sliding column to move downward, and the sliding column will drive the sealing disk into the air inlet. The bottom of the limit disk fits tightly with the bottom of the rotating groove to ensure the sealing of the balloon's air inlet. At the same time, the spring is squeezed and contracted, and the spring pulls the lever so that it will not move around when not in use, thereby enhancing the stability of the device's operation and preventing gas from leaking from the balloon. Under the action of the thread, the support column and the cylindrical tube are threadedly connected to facilitate carrying the blown balloon. BRIEF DESCRIPTION OF THE DRAWINGS

The lever 7 will drive the sliding column 8 to move downward, and the sliding column 8 will drive the sealing disk 9 to enter the air inlet 11. The bottom of the limit disk 2 fits tightly with the bottom of the rotating groove 4 to ensure the sealing of the balloon's air inlet. At the same time, the spring 10 is squeezed and contracted. The spring 10 pulls the lever 7 so that it will not move around when not in use, thereby enhancing the stability of the device operation and preventing gas from leaking from the balloon. Under the action of the thread, the support column 1 is threadedly connected to the cylindrical tube 3, which is convenient for carrying the blown balloon.
