Description

Technical Field

[0001] The utility model belongs to the technical field of air tightness detection equipment, in particular to an emergency flashlight battery shell leak detection tool. Background Art

[0002] The differential pressure method of air tightness testing is a testing method that uses the gas flow formula to calculate the amount of leakage by measuring the change in pressure in the container. Leakage in a closed container will inevitably cause the loss of gas mass in the container, causing the original pressure in the container to decrease. Therefore, the actual amount of gas leaked from the container can be calculated by measuring the value of the gas pressure reduction in the container; the working cycle of the differential pressure method of air tightness testing includes 4 processes, namely the inflation process, the balance process, the detection process and the exhaust process.

[0003] Most flashlights use new energy lithium batteries, which have the characteristics of long battery life and easy charging. Lithium batteries have high requirements for the sealing of the shell. If there are small cracks or cracks, leakage accidents will occur. Once the battery comes into contact with air, it is easy to spontaneously ignite and cause danger. Therefore, the utility model mainly prepares a leak detection tool, which works with the air tightness detection equipment to perform air tightness detection on the flashlight battery shell.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] like Figure 1-2 As shown: an emergency flashlight battery case leak detection tool, including a base 1 for support, the base is a square plate structure, and the bottom is also provided with rubber legs, which are located at the corners of the base, and a support seat 4 for supporting the battery case 3 is arranged on the upper side of the base 1, and the support seat 4 is provided with a first limiting groove 42 at the bottom of the battery case 3, and the side wall of the support seat 4 is provided with an air inlet 41 connected to the first limiting groove 42;

[0021] A support frame 2 is also fixed on the upper side of the base 1. The support frame is a plate structure and is vertically fixed to the base. A sealing cover 5 is installed above the support frame 2 corresponding to the battery casing 3, which is used to seal the upper opening side of the battery casing 3. The sealing cover 5 is lifted and lowered in coordination with the support frame 2 through a pressing device. The battery casing has a columnar shape and a shell structure. The upper and lower sides are opening sides. The bottom opening side is limited in the first limiting groove. The upper opening side is sealed by a sealing cover. When installing, align the lower side of the battery casing with the first limiting groove of the support seat, and then start the pressing device to drive the sealing cover to move downward. The sealing cover covers the upper opening side of the battery casing and seals it. After the battery casing is installed, it is tested by an airtightness detection device, the corresponding air inlet pipe is docked with the air inlet hole, and the gas airtightness is tested after the battery casing is inflated.

[0022] The device is simple and reliable to operate, can be tested conveniently, and the test results are accurate.

[0023] like Figure 3-4As shown: the bottom of the sealing cover 5 corresponds to the upper opening side of the battery case 3 and has a second limiting groove 51. The side of the second limiting groove 51 matches the side of the battery case 3. A contact plate 52 is installed in the second limiting groove 51. The contact plate 52 and the side of the second limiting groove 51 have an elastic leather ring 53, and the elastic leather ring 53 is arched downward. The elastic leather ring is made of rubber material and is used to connect the sealing plate and the notch position of the second limiting groove. When the sealing cover is pressed, the battery case contacts the contact plate, causing the contact plate to be compressed. Due to the compression of the contact plate, the elastic leather ring arches inward and contacts the outer side of the opening side of the battery case, thereby increasing the sealing contact surface and improving the sealing performance. A layer of rubber ring 54 is fixed at the connection between the contact plate 52 and the elastic leather ring 53. The rubber ring 54 is fixed to the contact plate 52 and is an integral structure with the elastic leather ring 53. The rubber ring 54 and the side of the contact plate 52 form a sealing groove. The sealing groove is used to limit the opening side of the battery casing and to form a sealing ring inside so that both the inner and outer sides of the corresponding opening side of the battery casing have a better sealing effect.

[0024] The upper side of the sealing cover 5 has a detachable rear cover plate 55, and the rear cover plate 55 has a limiting portion for contacting and limiting the compression distance of the contact plate 52. When the upper side of the battery casing contacts the contact plate, the contact plate is compressed under the action of the pressing device, and the contact plate is limited and compressed to the position of the limiting portion. The upper side of the sealing cover is an open side, and a support ring is provided on the corresponding inner side wall for installing the rear cover plate. The support ring and the rear cover plate have corresponding openings and are fixed by bolts.

[0025] like Figure 1 As shown: the pressing device is a cylinder assembly 6. Specifically, it involves a cylinder and a guide rod, which are driven by pneumatics. A detachable holder 43 is provided on the upper side of the support seat 4. The center of the holder 43 is a first limiting groove 42. A sealing gasket 44 is provided between the holder 43 and the support seat 4. A circular hole for inflation is provided in the center of the sealing gasket 44. The holder and the support seat together form a first limiting groove. The holder and the support seat are detachably installed, which is convenient for replacing the sealing gasket and preventing the sealing gasket from aging and cracking and affecting the performance.

[0026] This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can better understand and utilize the present invention.
