Description

Technical Field

[0001] The utility model relates to the technical field of sealing detection equipment, in particular to a waterproof sealing negative pressure detection device. Background Art

[0002] The negative pressure seal tester is an instrument used for sealing performance testing. It evacuates the vacuum chamber in the form of negative pressure to create a pressure difference between the inside and outside of the sample immersed in water, and observes the escape of gas in the sample to determine the sealing performance of the sample. When the sealing performance of the sample is good, its own waterproof performance is also guaranteed.

[0003] However, in the prior art, some existing sealed negative pressure detectors generally place a detection barrel directly on the top of the sealed negative pressure detector when detecting the sealing of an object. There is a lack of a fixing mechanism for the detection barrel, which may cause the detection barrel to topple over due to external force, thereby easily affecting the normal detection of the sample in the detection barrel. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art: the sealed negative pressure detector lacks a fixing mechanism for the detection barrel, which may cause the detection barrel to topple due to external force, thereby easily affecting the normal detection of the sample in the detection barrel.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a waterproof sealed negative pressure detection device, comprising a negative pressure sealing detector body, a detection barrel is placed on the top of the negative pressure sealing detector body, and a closing cover is arranged on the top of the detection barrel, a track rod is fixed on the surface of the negative pressure sealing detector body, and a spring is sleeved on the surface of the track rod, a movable plate is slidably connected to the surface of the track rod, an elastic clamping member is fixedly connected to the surface of the movable plate, an extension plate is fixed to one end of the movable plate, a vertical plate is fixed to the surface of the negative pressure sealing detector body on one side of the extension plate, and a positioning member is slidably connected to the vertical plate, and one end of the positioning member is connected to the extension plate.

[0006] As a preferred implementation, a sealing ring is fixed at the edge of the opening of the detection barrel, and the sealing ring is snap-connected with the closing cover.

[0007] As a preferred embodiment, a pressing plate is fixed to the lower surface of the closing cover, and holes are formed on the surface of the pressing plate.

[0008] As a preferred implementation, an anti-slip texture is provided on the extrusion surface of the elastic clamp.

[0009] As a preferred implementation, a counterweight is fixedly connected to one side surface of the positioning member.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] The utility model manually pushes the movable plate to make it move in a straight line toward the middle of the negative pressure sealing detector body along the track rod, and then the elastic clamping piece will contact the detection barrel and clamp it and fix it, and when the movable plate moves, the extension plate will also move at the same time, so that the through hole on the extension plate moves toward the positioning piece, and when the elastic clamping piece clamps the detection barrel, the positioning piece will also slide down into the through hole of the extension plate for positioning, thereby ensuring the stability of the elastic clamping piece when clamping.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] like Figure 1-4As shown, the utility model provides a technical solution: a waterproof and sealed negative pressure detection device, including a negative pressure and sealed detector body 1, the negative pressure and sealed detector body 1 includes a vacuum pump, an air pipe and a control panel, the vacuum pump is started by operating the control panel of the negative pressure and sealed detector body 1 to evacuate the air pipe, when the closing cover 4 is in a state of closing the top opening of the detection barrel 2, the air pipe installed on the closing cover 4 will evacuate the inside of the detection barrel 2, so that a vacuum space is formed inside the detection barrel 2, a detection barrel 2 is placed on the top of the negative pressure and sealed detector body 1, the detection barrel 2 is used to load a water source and sink a sample into water, when the detection barrel 2 is in a vacuum, it is convenient to observe whether there is gas escaping from the sample, so as to understand the waterproof and airtightness of the sample, and a closing cover 4 is arranged on the top of the detection barrel 2, the closing cover 4 plays the role of closing the opening of the detection barrel 2, a track rod 6 is fixed on the surface of the negative pressure and sealed detector body 1, and a spring is sleeved on the surface of the track rod 6 The spring 7 releases the positioning state of the movable plate 8 and the extension plate 10, and with the help of the rebound of the spring 7, it plays a role in allowing the elastic clamping member 9 to quickly release the clamping and fixing of the detection barrel 2. The movable plate 8 is slidably connected to the surface of the track rod 6, and the elastic clamping member 9 is fixedly connected to the surface of the movable plate 8. The elastic clamping member 9 is clamped and fixed to the detection barrel 2 by pushing the movable plate 8. The extension plate 10 is fixed at one end of the movable plate 8. The surface of the negative pressure sealing detector body 1 is located on one side of the extension plate 10 and is fixed with a vertical plate 11, and a positioning member 12 is slidably connected to the vertical plate 11. One end of the positioning member 12 is connected to the extension plate 10 through the extension plate 10. When the movable plate 8 moves, the extension plate 10 will also move at the same time, so that the through hole on the extension plate 10 moves toward the positioning member 12. When the elastic clamping member 9 clamps the detection barrel 2, the positioning member 12 will also slide into the through hole of the extension plate 10 for positioning, thereby ensuring the stability of the elastic clamping member 9 when clamping.

[0021] Example 2

[0022] like Figure 1-4 As shown, a sealing ring 3 is fixed at the edge of the opening of the detection barrel 2, and the sealing ring 3 is snap-connected with the closing cover 4. With the help of the sealing ring 3, the sealing performance of the closing cover 4 when it is covered on the detection barrel 2 is improved. A pressing plate 5 is fixed to the lower surface of the closing cover 4, and holes are provided on the surface of the pressing plate 5. With the help of the pressing plate 5, a lighter sample is pressed into the water. The setting of the holes is used to reduce the resistance encountered when the pressing plate 5 is pressed into the water. An anti-slip texture is provided on the extrusion surface of the elastic clamp 9. The setting of the anti-slip texture improves the stability of the elastic clamp 9 in clamping the detection barrel 2. A counterweight block 13 is fixedly connected to the surface of one side of the positioning member 12. Under the action of the weight of the counterweight block 13 itself, one end of the positioning member 12 can fall more naturally and quickly into the through hole of the extension plate 10.

[0023] Working principle:

[0024] like Figure 1-4 As shown, when the utility model is in use, the user first fills the detection barrel 2 with water, and then places it on the top of the negative pressure sealing tester body 1, then puts the sample into the detection barrel 2, and then allows the closing cover 4 to engage with the sealing ring 3, and then pushes the movable plate 8 with both hands to make it move in a straight line along the track rod 6 toward the detection barrel 2. During this period, the spring 7 is squeezed and contracted. After moving a certain distance, the elastic clamping member 9 clamps and fixes the detection barrel 2. At the same time, when the movable plate 8 moves, the extension plate 10 will also move at the same time, so that the through hole on the extension plate 10 moves toward the positioning member 12. When the elastic clamping member 9 clamps the detection barrel 2, the positioning member 12 will also slide down the vertical plate 11 into the through hole of the extension plate 10 for positioning, thereby ensuring the stability of the elastic clamping member 9 when clamping. After that, both hands can be freed to operate the negative pressure sealing tester body 1 to perform waterproof sealing detection of the sample.
