Description

Technical Field

[0001] The utility model relates to a spiral joint leakage detection device, belonging to the technical field of medical equipment. Background Art

[0002] The spiral joint is a peritoneal dialysis injection molded part. After it is produced, it will be installed with external pipes produced by multiple manufacturers. In order to prevent leakage or poor docking due to product sealing factors during use, it is necessary to perform a leak test on the spiral joint installed on the external pipe before use.

[0003] However, currently, a manual inspection method is used, that is, manually connecting the spiral joint installed on the external pipe to the air pump, and then placing it in a basin to observe whether bubbles are generated, so as to judge whether the sealing of the connection between the spiral joint and the external pipe is good. The existing inspection method is inefficient and labor-intensive for workers. Utility Model Content

[0004] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art, to provide a spiral joint leakage detection device, to improve the detection efficiency, and to reduce the labor intensity of workers.

[0005] The utility model discloses a spiral joint leak detection device, comprising a water tank, a plurality of detection brackets, a support plate, a power mechanism, an air pipe and an air pump. The spiral joint is placed on the detection bracket, the detection brackets are evenly distributed on the support plate, the support plate is placed in the water tank, the support plate can drive the detection brackets to move up and down in the water tank, the output end of the power mechanism is connected to the support plate, and the air pump is connected to an external pipeline through the air pipe.

[0006] Install the spiral joint installed on the external pipeline on the detection bracket, connect the air pump to the external pipeline through the air pipe, turn on the air pump, start the power mechanism, move the support plate downward, and drive the spiral joint downward at the same time, immerse the spiral joint in water, and observe whether there is any leakage. If the sealing between the spiral joint and the external pipeline is poor, gas will leak from the connection between the spiral joint and the external pipeline, and bubbles can be clearly seen in the water, so as to judge which spiral joint has poor sealing with the external pipeline. Batch detection is realized, detection efficiency is improved, and labor intensity of workers is reduced.

[0007] A slideway is arranged in the water tank corresponding to the support plate, and the support plate is slidably connected to the slideway. The slideway can reduce friction and increase smoothness of movement when the support plate moves up and down, and can guide the support plate to move up and down, thereby preventing the support plate from tilting during movement.

[0008] A fan is arranged on the water tank corresponding to the detection bracket. After the detection is completed, the support plate is lifted up to above the water surface, and the detection bracket, the spiral joint and the external pipe are raised to above the water surface along with the support plate. The fan is started to dry the moisture on the spiral joint and the external pipe at the same time, without manual drying, which reduces labor intensity and improves work efficiency.

[0009] The detection bracket is provided with a through hole, and the spiral joint passes through the through hole on the detection bracket, thereby achieving the fixation of the spiral joint.

[0010] A U-shaped groove is arranged on the top of the detection bracket. The external pipe is first installed on the spiral joint, and then the spiral joint with the external pipe is installed from top to bottom in the U-shaped groove on the detection bracket. The U-shaped groove is convenient for installation and removal of the spiral joint.

[0011] The detection bracket is provided with a slot corresponding to the flange protrusion on the spiral joint. The flange protrusion on the spiral joint is inserted into the slot, so that the spiral joint is installed more stably and prevented from falling.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The utility model realizes airtightness detection of multiple spiral joints with external pipes at the same time by arranging a plurality of detection brackets on the support plate, thereby improving the detection efficiency. By setting a power mechanism corresponding to the support plate, the automation of the spiral joints entering and exiting water is realized, thereby reducing the labor intensity of workers.

[0014] (2) A slideway is provided in the water tank corresponding to the support plate, and the support plate is slidably connected to the slideway. The slideway can reduce friction and increase smoothness of movement when the support plate moves up and down, and can guide the support plate to move up and down, thereby preventing the support plate from tilting during movement.

[0015] (3) A fan is set on the water tank corresponding to the detection bracket. After the detection is completed, the support plate is lifted up to the water surface. The detection bracket, spiral joint and external pipe are raised to the water surface with the support plate. The fan is started to blow away the moisture on the spiral joint and the external pipe at the same time. There is no need for manual drying, which reduces labor intensity and improves work efficiency.

[0016] (4) A slot is provided on the detection bracket corresponding to the flange protrusion on the screw joint. The flange protrusion on the screw joint is inserted into the slot, making the installation of the screw joint more stable and preventing the screw joint from falling off.

A U-shaped groove is arranged on the top of the detection bracket 5. The spiral joint 4 includes a first part 41, a second part 42, a third part 43 and a fourth part 44. The first part 41, the second part 42, the third part 43 and the fourth part 44 are arranged in sequence to constitute the spiral joint 4 as a whole. The fourth part 44 of the spiral joint 4 is inserted into the U-shaped groove. A card slot 13 is also arranged on the detection bracket 5. The flange protrusion on the spiral joint 4 is card-engaged with the card slot 13. The flange protrusion is the third part 43 of the spiral joint 4. Figure 3 The detection brackets 5 are evenly distributed on the support plate 6, and the support plate 6 is placed in the water tank 11. The support plate 6 can drive the detection bracket 5 to move up and down in the water tank 11. The output end of the power mechanism 8 is connected to the support plate 6. The power mechanism 8 is a cylinder, and the cylinder is fixed to the water tank 11 through the second support plate 9.
