Description

Technical Field

[0001] The utility model relates to the field of caps, in particular to a cap sealing performance testing device. Background Art

[0002] A cap is a device for fixing a lithium battery. It is usually covered on the top of the lithium battery and fixed to a bracket by screws or clamps. The cap is usually made of a strong material and its appearance is a device similar to a lid, which can provide a stable fixing effect and protect the lithium battery from the external environment. At present, before the cap is used, it is necessary to detect its sealing performance, which is an important measure to ensure product quality, safety and compliance requirements, can prevent leakage, maintain product stability, and meet regulatory and standard requirements, and improve user experience.

[0003] At present, when detecting the sealing performance of the cap, it is usually clamped on the outer surface of the cap by a clamp. However, when testing the sealing performance, after the clamping detection, it is necessary to change the clamping position and perform reciprocating detection, which will lead to a low detection efficiency. And if it is a single detection, it may cause errors in the detection result of the sealing performance due to the blockage of the clamp. Therefore, a cap sealing performance testing device is proposed for the above problems. Summary of the Utility Model

[0007] Preferably, the bottom end of the threaded rod penetrates through the fixed table and extends to the bottom end of the fixed table. The operator can rotate the bottom end of the threaded rod to drive it to rotate. The threaded sleeve is slidably connected inside the inner groove. When the threaded rod is rotated, the threadedly connected threaded sleeve will slide downward inside the inner groove.

When the push rod is pushed, it will slide inside the guide sleeve, and at this time, the push rod will push the abutting block to slide inside the guide rail.

[0009] Preferably, there are four guide rails and they are circumferentially distributed on the surface of the top end of the fixed table. The abutting block is adapted to contact the inner wall of the cap body, and the abutting blocks inside the multiple guide rails limit the cap body from the inside.

[0023] The following is a further detailed description of the present application Figures 1-5 with reference to the attached

[0024] The embodiment of the present application discloses a cap sealing performance testing device. Refer to Figures 1-2 , a cap sealing performance testing device, including a fixed platform 1 and a cap body 2; the cap body 2 is located above the cap body 2, an internal clamping component 3 is arranged at the top end of the fixed platform 1, and a limiting component 4 is arranged at the top of the fixed platform 1;

[0025] Refer to Figures 2-4, the internal clamping assembly 3 includes an inner groove 31 opened at the top end of the fixed table 1. A threaded rod 32 is rotatably connected inside the inner groove 31. A threaded sleeve 33 is threadedly connected to the surface of the threaded rod 32. The bottom end of the threaded rod 32 penetrates through the fixed table 1 and extends to the bottom end of the fixed table 1. The operator can rotate the bottom end of the threaded rod 32 to drive its rotation. The threaded sleeve 33 is slidably connected inside the inner groove 31. When the threaded rod 32 is rotated, it will drive the threadedly connected threaded sleeve 33 to slide downward inside the inner groove 31. A rotating rod 34 is rotatably connected to the surface of the threaded sleeve 33. One end of the rotating rod 34 away from the threaded sleeve 33 is rotatably connected to a push rod 35. A guide rail 36 is fixedly installed on the surface of the top end of the fixed table 1. A telescopic rod 37 is fixedly installed inside the guide rail 36. One end of the telescopic rod 37 away from the inner wall of the guide rail 36 is fixedly installed with an abutting block 38. There are four guide rails 36 and they are circumferentially distributed on the surface of the top end of the fixed table 1. The abutting block 38 is adapted to contact the inner wall of the cap body 2. The abutting blocks 38 inside the multiple guide rails 36 limit it from the inside of the cap body 2. A guide sleeve 39 is fixedly installed at the top end of the guide rail 36. The push rod 35 is slidably connected inside the guide sleeve 39. The abutting block 38 is slidably connected inside the guide rail 36. When the push rod 35 is pushed, it will slide inside the guide sleeve 39. At this time, the push rod 35 will push the abutting block 38 to slide inside the guide rail 36.

[0026] Referring to Figure 5 , the limiting assembly 4 includes a bottom groove 41 opened at the top of the fixed table 1. A guide rod 42 is fixedly installed inside the bottom groove 41. A slider 43 is slidably connected to the surface of the guide rod 42. A vertical rod 44 is fixedly installed at the top end of the slider 43. A spring 45 is fixedly installed on the surface of the vertical rod 44. The top of the vertical rod 44 is slidably connected to a pressing plate 46. The slider 43 is slidably connected inside the bottom groove 41. The top end of the spring 45 is fixedly installed at the bottom end of the pressing plate 46. The resilience of the spring 45 can pull the pressing plate 46 to move downward.

[0027] Working principle: After the operator places the cap body 2 on the top end of the fixed table 1, at this time, the bottom end of the threaded rod 32 can be rotated. At this time, the threaded rod 32 will drive the threadedly connected threaded sleeve 33 to slide downward inside the inner groove 31. When the threaded sleeve 33 moves downward, it will push the rotating rod 34. At this time, after the rotating rod 34 is pushed, the bottom end will gradually move away from the threaded rod 32. At this time, the rotating rod 34 will push the push rod 35 to slide inside the guide sleeve 39. The push rod 35 will push the fixedly connected abutting block 38 to slide inside the guide rail 36 until the abutting block 38 moves to abut against the inside of the cap body 2, so as to limit it inside the cap body 2.

[0028] After that, the test strip detected by the operator is placed on the top of the fixing table 1. At this time, the pressing plate 46 is pulled upward to stretch the spring 45 and make it elongate, so that the pressing plate 46 moves upward and disengages from the top of the fixing table 1. Then, the operator adjusts the position of the test strip so that it is between the pressing plate 46 and the fixing table 1. After that, the operator releases the pressing plate 46, and the pressing plate 46 will press on the top of the test strip under the action of the resilience of the spring 45, so that the test strip is stably limited on the top of the fixing table 1. Then, the operator applies the test liquid to the outer surface of the cap body 2 and evenly applies the liquid on the surface of the cap body 2 by means of tools such as a brush. After that, the operator waits for a period of time to observe whether the test strip is permeated, so as to detect the sealing performance of the cap. After the detection is completed, the cap can be cleaned.
