In some flexible gloves, such as medical latex gloves, good sealing properties are required.

Therefore, in the glove production process with the sealing requirement, in order to avoid the glove from being damaged, the sealing detection needs to be carried out on the glove.

In the case of performing the tightness test on the glove, a method is generally adopted in which a flexible glove is fixed to a glove fixing structure such as a glove fixing flange, an inflator is installed to the glove fixing structure, the flexible glove is inflated by the inflator, and then whether the air pressure in the flexible glove is changed is detected to determine whether the glove is broken or not.

Before inflation detection is carried out, the inflatable sealing ring on the inflatable device is required to be inflated, and the inflated inflatable sealing ring is tightly clamped between the gap between the inner wall of the glove fixing structure and the outer wall of the inflatable device so as to seal the glove fixing structure.

However, in actual operation, there is a problem in that the inflation sealing ring bursts during inflation thereof due to no external restriction, because the inflator is not installed in place.

In order to solve the problem that an inflatable sealing ring bursts due to no external limitation in the inflation process because an inflation device is not installed in place in the detection process of the tightness of the flexible glove, the technical conception of the application is as follows: and a position detection device is arranged on the glove tightness detection device, and if the glove tightness detection device is detected to be installed at a correct position, the position detection device sends out a trigger signal for triggering the inflation of the inflatable sealing ring.

The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

In one possible embodiment of the application, a glove tightness detection device is provided. Fig. 1 is a side view of a glove tightness detection device according to an embodiment of the present application, as shown in fig. 1, the device includes:

the sealing plate 110, sealing plate 110 one side is fixed with sealing body 120, and sealing body 120 outer wall cover is equipped with inflatable seal 130, and sealing body 120 outer wall is equipped with position detection unit 140, and position detection unit 140 is used for:

after the sealing body 120 stretches into the glove fixing flange, when the sealing body 120 is detected to reach the preset installation position, a trigger signal is sent out, and the trigger signal is used for triggering the inflation of the inflatable sealing ring.

In this embodiment, the seal plate 110 is preferably circular in shape so as to mate with the flange of the glove mounting flange. On one side of the sealing plate 110, a sealing body 120 is fixed, and the sealing body 120 is preferably cylindrical in shape so as to be engaged with the inner wall of the glove fixing flange. The sealing plate 110 and the sealing body 120 may be made of plastic.

Optionally, an annular groove is formed on the outer wall of the sealing body 120, and an inflatable sealing ring 130 is sleeved in the annular groove. In actual operation, in the process of detecting inflation of the glove, the glove needs to be fixed on the glove fixing flange, and after the sealing body 120 stretches into the glove fixing flange, a gap exists between the sealing body 120 and the inner wall of the glove fixing flange, and the tightness of the glove fixing flange needs to be ensured because the air pressure inside the glove needs to be detected. The inflatable sealing ring 130 made of flexible materials is inflated to expand, so that the inflated inflatable sealing ring 130 clamps a gap between the outer wall of the sealing body 120 and the inner wall of the glove fixing flange to play a role in sealing the glove fixing flange, and then the glove is inflated through the sealing body 120.

In order to solve the problem that the inflation sealing ring bursts due to no external limitation in the inflation process because the inflation device is not installed in place in the inflation process of the flexible glove tightness detection process, in this embodiment, the outer wall of the sealing body 120 is provided with the position detection unit 140, and optionally, the position detection unit 140 may include a position sensor disposed on the outer wall of the sealing body 120.

After the sealing body 120 extends into the glove fixing flange, the position detecting unit 140 needs to detect whether the sealing body 120 is installed at a preset installation position, and in the preset installation position, the inflatable sealing ring 130 can be guaranteed to be completely wrapped by the inner wall of the glove fixing flange, and in this state, the inflatable sealing ring 130 is inflated, so that the problem that the inflatable sealing ring 130 bursts due to no external limitation in the inflation process can be avoided.

The position detecting unit 140 detects that the sealing body 120 is mounted at a preset mounting position and then emits a trigger signal. The position detecting unit 140 may detect the position of the sealing body 120 through a position sensor provided on the outer wall of the sealing body 120, and emit a trigger signal when the position sensor detects the glove fixing flange and detects that the current position of the sealing body 120 is at a preset installation position. Optionally, the position sensor is disposed on the outer wall of the sealing body 120 and is located on a side of the inflatable sealing ring 130 away from the sealing plate 110.

Optionally, the trigger signal may be sent to a terminal device connected to the apparatus, such as a computer, and the trigger signal is displayed on a screen of the terminal device as an in-place apparatus installation prompt message, where the operator receives the in-place apparatus installation prompt message and may inflate the inflatable seal ring 130; the trigger signal may also be an audible signal that prompts the operator to inflate the inflatable sealing ring 130.

Alternatively, the trigger signal may also be used to open a solenoid valve on the inflation line of the inflatable seal 130 so that gas may enter the inflatable seal 130.

For easy access, a handle 160 is optionally secured to the sealing plate 110.

The technical effects of this embodiment are: the position detection unit 140 is arranged on the outer wall of the sealing body 120, after the sealing body 120 stretches into the glove fixing flange, the triggering signal is sent out after the sealing body 120 reaches the preset installation position, the inflatable sealing ring 130 can be inflated after the triggering signal is received, so that the inflatable sealing ring 130 can be inflated after the sealing body 120 is installed in place, and the problem that the inflatable sealing ring 130 bursts due to no external limitation in the inflation process of the inflatable sealing ring is avoided.

Fig. 2 is a cross-sectional view of another glove tightness detecting device according to an embodiment of the present application, as shown in fig. 2, in order to inflate a glove and detect the pressure inside the glove, in one possible embodiment of the present application, an inflation solenoid valve 210 and a pressure detecting solenoid valve 220 are fixed inside a sealing body 120, an inflation port of the inflation solenoid valve 210 and an air inlet port of the pressure detecting solenoid valve 220 are located on an end surface 150, and the end surface 150 is a surface of the sealing body 120 opposite to a sealing plate 110.

In actual operation, after the inflation solenoid valve 210 is opened, the glove can be inflated through the inflation port of the inflation solenoid valve 210; after the pressure detection solenoid valve 220 is opened, the gas inside the glove can be transmitted to the pressure sensor through the gas inlet of the pressure detection solenoid valve 220, thereby detecting the pressure inside the glove.

Alternatively, as shown in fig. 2, to inflate the inflation solenoid valve 210, an air inlet of the inflation solenoid valve 210 is connected to the first air tube 211 in a conductive manner; in order to enable the gas inside the glove to be transmitted to the pressure sensor through the gas inlet of the pressure detection electromagnetic valve 220, the gas outlet of the pressure detection electromagnetic valve 220 is connected with the second gas pipe 221 in a conducting manner, and the first gas pipe 211 and the second gas pipe 221 extend to the interface 230 on the sealing plate 110. Meanwhile, in order to inflate the inflatable sealing ring 130, inside the sealing body 120, the inflatable sealing ring 130 is connected to the third air pipe 131 in a conducting manner, and the third air pipe 131 extends to the interface 230, and the interface 230 is located on the sealing plate 110.

The first air pipe 211, the second air pipe 221 and the third air pipe 131 may be metal pipes, in actual use, a main pipe insertion port 230 including three access pipes may be used, and the three access pipes in the main pipe are respectively connected with the first air pipe 211, the second air pipe 221 and the third air pipe 131 in a conducting manner, so that the inflation sealing ring 130 and the inflation electromagnetic valve 210 may be inflated from the outside. The gas in the glove may be transmitted to an external pressure sensor through the second gas pipe 221, thereby monitoring the pressure change in the glove in real time.

Since the glove fixing flange is required to be sealed well when detecting the pressure of the glove, in the present application, the inflation of the glove can be performed through the inflation port of the inflation electromagnetic valve 210 only when the pressure of the inflation sealing ring 130 reaches a predetermined value, that is, the inflation sealing ring 130 completes the sealing of the gap between the outer wall of the sealing body 120 and the inner wall of the glove fixing flange. Fig. 3 is a top view of another glove tightness test apparatus according to an embodiment of the present application, as shown in fig. 3, in one possible embodiment of the present application, the apparatus further includes an activation button 310 and a control unit, wherein the activation button 310 is located on the sealing plate 110, and the control unit is configured to control the opening of the inflation port of the inflation electromagnetic valve 210 under the triggering of the activation signal of the activation button 310.

Specifically, in this embodiment, the control unit may be a chip having a control function. After the operator presses the start button 310, the start button 310 sends a start signal to the control unit, and the control unit opens the inflation electromagnetic valve 210 after receiving the start signal, so that the glove fixed to the glove fixing flange can be inflated through the inflation electromagnetic valve 210.

In a possible embodiment of the application, the control unit is further adapted to:

the control start button 310 is in a deactivated state in which a start signal of the start button 310 is not executed; or,

the control start button 310 is in an activated state in which a start signal of the start button 310 is executed.

When the external pressure sensor detects that the pressure of the inflatable sealing ring 130 reaches a preset value, that is, the inflatable sealing ring 130 seals a gap between the inner wall of the fixed flange of the glove and the outer wall of the sealing body 120, the external control terminal device can send an activation control signal to the control unit in a wired transmission or wireless transmission mode. When the control unit receives the activation control signal, the start button 310 is in an activated state at this time, and the start signal of the start button 310 is executed in the activated state. When the external control terminal device does not transmit the activation control signal to the control unit, the control unit controls the start button 310 to be in a deactivated state in which the start signal of the start button 310 is not executed.

The technical effects of this embodiment are:

by controlling the activation button 310 in a deactivated state or an activated state by the control unit, it is ensured that the glove fixing flange is sealed well before the glove is inflated when the activation condition is that the inflation of the inflatable sealing ring 130 is completed.
