Description

Technical Field

[0001] The present application belongs to the technical field of automobile lamps, and in particular relates to a sealing detection rain-proof structure for automobile lamps. Background Art

[0002] In the field of automotive technology, automotive lamps are an important part of automobiles. Automotive lamps must be tested for air tightness before leaving the factory. Automotive lamps are mainly made of masks and bottom shells. When the masks and bottom shells are produced, they have been tested for air tightness. After the finished automotive lamps are completed, the entire lamp must be tested for air tightness. The masks and bottom shells of automotive lamps are welded together. At this time, the air tightness test of the lamps is mainly for the detection of the welding edges of the lamps.

[0003] The existing automobile lamp sealing detection rain shower structure is not very safe. It requires manual placement of the lamp in the device and the use of a cylinder to press and inflate the pressure plate. Since airtightness testing is necessary and there are many workpieces, workers may still have one hand in the device after a long period of work and use the other hand to open the cylinder, causing safety accidents.

[0004] To this end, we propose an automobile lamp sealing detection rain structure to solve the above problems. Utility Model Content

[0005] The purpose of the present application is to solve the problem of low safety in the prior art and to propose a rain-proof structure for sealing detection of automobile lamps.

[0006] In order to achieve the above purpose, this application adopts the following technical solutions:

[0007] The lockhole that is formed on the upper and lower sides of the box body is formed on the upper and lower ends of the box body, and the lockhole that is formed on the lower and lower ends of the box body is formed on the lower and upper ends of the box body is formed on the box body.

[0008] Preferably, the synchronization structure includes a rotating rod rotatably connected to both sides of the top of the cavity, the upper end of the rotating rod is fixedly sleeved with a transmission wheel with a meshing gear, and a synchronization component for synchronously rotating the two rotating rods is provided between the lower ends of the two rotating rods.

[0009] Preferably, the synchronization assembly includes a sprocket fixedly connected to the lower end of the rotating rod, and a chain is commonly sleeved between the two sprockets.

[0010] Preferably, the pressing assembly comprises a cylinder fixedly mounted downward on a horizontal plate, the lower end of the cylinder is fixedly connected to a pressing plate, and the bottom surface of the pressing plate is larger than the inner ring of the sealing ring and smaller than the outer ring of the sealing ring.

[0011] Preferably, a placing table is fixedly connected to the center of the bottom wall of the box body, the top surface of the placing table is funnel-shaped, a plurality of through grooves for water to flow down are opened on the placing table, and a water hole and a water valve are opened at the bottom of the box body.

[0012] Preferably, the top surface of the placement table is lower than the bottom surface of the sealing ring and higher than the upper end of the vent hole.

[0013] To sum up, the technical effects and advantages of the present application are as follows: compared with the existing devices, the automobile lamp sealing detection rain structure drives the rotating shaft to rotate through the limit block, and the gear drives the tooth plate to move. The tooth plate rotates synchronously with the two gears on the same side, and the four gears on both sides are rotated synchronously through the synchronization structure, so as to realize the synchronous rotation of the four limit blocks, and then realize the limit safety protection of the pressure plate. Compared with the existing devices, it avoids the problem that the worker may keep one hand in the device after working for a long time and use the other hand to open the cylinder, which may cause a safety accident, thereby improving the safety of the operation of the device.

The tooth plate 10 meshes with the two gears 9, and a synchronization structure for synchronously rotating the four gears 9 on both sides is provided in the cavity 6 between the two tooth plates 10. The rotating shaft 7 is driven to rotate by the limit block 8, and the gear 9 drives the tooth plate 10 to move. The tooth plate 10 rotates synchronously with the two gears 9 on the same side, and the synchronous rotation of the four gears 9 on both sides is achieved through the synchronization structure, thereby achieving the synchronous rotation of the four limit blocks 8, and then achieving the limit safety protection of the pressure plate 20. Compared with the existing device, it avoids the problem that the worker may keep one hand in the device after a long period of work and use the other hand to open the cylinder 19, thereby improving the safety of the operation of the device.

[0021] Reference Figure 4 A plurality of water spray ports 11 are provided on the side wall of the box body 1 below the sealing ring 4, a water pump 12 connected to the water spray ports 11 is fixedly installed on one side of the box body 1, and a rain test is achieved through the water pump 12 and the water spray ports 11, a vent hole 13 is opened on one side of the box body 1 below the sealing ring 4, and an air pump 14 is installed at the vent hole 13, and an airtight test is achieved through the vent hole 13 and the air pump 14.
