Technical Field

[0001] The utility model relates to the technical field of inner tube production, in particular to an air leakage detection device for inner tube production. Background Art

[0002] The inner tube is commonly known as the inner tire. It is a ring-shaped elastic rubber product. The main material is rubber, which is generally divided into natural rubber and butyl rubber. It is an air-bearing container for inflation and vibration reduction. It is used as an auxiliary air-bearing pressure container in the inner cavity of truck, motorcycle, bicycle, and rickshaw tires. In order to ensure the quality of the inner tube, personnel need to perform air leakage detection on the inner tube.

[0003] In the process of personnel actually performing air leakage detection on inner tubes, personnel are required to use their hands to press the inner tube so that the outer wall of the inner tube is immersed in the water source, thereby detecting whether the inner tube is leaking. However, when the number of inner tubes to be detected is large, personnel cannot process a large number of tires in batches individually, which will increase the workload of personnel and further reduce their work efficiency. Therefore, a air leakage detection device for inner tube production is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide an air leakage detection device for inner tube production, which solves the problem in the prior art that personnel need to use their hands to press the inner tube so that the outer wall of the inner tube is immersed in a water source, thereby detecting whether the inner tube is leaking. However, when the number of inner tubes to be detected is large, personnel cannot process a large number of tires in batches individually, which increases the workload of personnel and further reduces the work efficiency of personnel.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A leakage detection device for inner tube production comprises an outer frame, an inner cavity of the outer frame is horizontally provided with a downward pressure frame, one side of the outer frame is vertically provided with a screw rod, the outer ring of the screw rod is provided with a threaded sleeve, connecting rods are fixedly connected to both sides of the upper surface of the downward pressure frame, one end of one of the connecting rods is fixedly connected to one side of an adjacent threaded sleeve, and one side of the outer frame is fixedly connected to a water inlet pipe.

[0007] Preferably, support legs are fixedly connected to the four corners of the bottom of the outer frame.

[0008] Preferably, a motor is installed on one side of the outer frame, and the bottom of the screw rod is drivingly connected to the output shaft of the motor.

[0009] Preferably, a bottom plate is fixedly connected to the lower portion of an outer wall of one side of the outer frame, a sliding rod is fixedly connected to the top of the bottom plate, a sliding sleeve is slidably connected to the outer ring of the sliding rod, and one side of the outer ring of the sliding sleeve is fixedly connected to one end of an adjacent connecting rod.

[0010] Preferably, a valve is installed on the outer ring of the water inlet pipe.

[0012] The utility model has at least the following beneficial effects:

[0013] When in use, the personnel first put the inner tube into the outer frame, and then inject water into the inner part of the outer frame through the water inlet pipe. Affected by the buoyancy of the water source, the inner tube will float on the water surface, and the personnel put the lower pressure frame into the inner cavity of the outer frame, so that the screw sleeve cooperates with the outer ring of the screw rod, and the sliding sleeve cooperates with the outer ring of the sliding rod. Driven by the motor, the screw rod rotates, so that the screw sleeve drives the corresponding connecting rod to adjust the position. At this time, the lower pressure frame also moves downward, squeezing the inner tube inside the outer frame, thereby achieving a situation where the inner tube is completely immersed in the inner cavity of the outer frame and immersed in the water source. The personnel observe whether there are obvious bubbles around the inner tube through the outer frame, so as to determine whether the inner tube is leaking. Through the structural design, the personnel can perform air leakage detection on the inner tubes in batches, avoiding the situation that the tire floats in the water source and cannot be immersed in the water source, providing convenience for the personnel's rapid detection, reducing the operating steps of the personnel in the detection, and improving the detection efficiency.

[0014] The utility model also has the following beneficial effects:

[0015] By setting the supporting legs, the stable support for the bottom of the outer frame is enhanced. By setting the screw rod, personnel can control the displacement of the screw sleeve in different directions by rotating the screw rod. By setting the sliding rod and the sliding sleeve, the situation where the screw sleeve rotates along with the screw rod is avoided. By setting the valve, personnel can control the connectivity of the water pipe. By setting the downward pressure frame, the inner tube inside the outer frame can be effectively pressed down.
