Technical Field

[0001] The utility model relates to the technical field of camera air tightness detection, in particular to a camera air tightness detection device with a protective function. Background Art

[0002] Cameras are commonly used for surveillance recording in various fields and are often installed in various open-air places. They need to be exposed to the sun or rain for a long time. There are strict requirements for cameras installed outside. They must be able to prevent the entry of other external objects and must have good sealing. Therefore, after the camera is produced and assembled, it is necessary to use camera airtightness testing equipment to test its sealing to ensure that the sealing of the assembled camera meets the requirements.

[0003] When using the current camera air tightness testing equipment, staff often find that the upper mold cavity and the lower mold cavity in the current camera air tightness testing equipment are directly exposed. When the equipment is not in use, a large amount of dust and particles will enter. During the detection process, the dust and particles may enter the camera and affect its performance. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art and to propose a camera airtightness detection device with a protective function.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a camera airtight detection equipment with a protective function, including an equipment table, a lower mold is arranged on the equipment table, a cylinder is arranged on the equipment table, an upper mold is fixedly connected to the piston rod of the cylinder, a compressor is fixedly connected to the lower mold through a hose, an analyzer is fixedly connected to the compressor through a pipeline, a protective structure is arranged on the equipment table, the protective structure is mainly composed of a protective cover, the protective cover is fixedly connected to the equipment table, the protective cover is fixedly connected to the cylinder, and a door panel is slidably inserted on the protective cover.

[0006] The effects achieved by the above components are: placing the camera to be tested in the lower mold, starting the cylinder, the piston rod of the cylinder drives the upper mold to descend, and connects with the lower mold to form a closed test chamber, starting the compressor, and the compressor injects a certain pressure of gas into the lower mold, allowing the gas to stabilize in the test chamber for a period of time so that the gas pressure is evenly distributed on the surface of the camera. The staff operates the analyzer to monitor the pressure changes in the test chamber. If there is a leak in the product, the gas will escape from the leak, causing the pressure in the test chamber to drop. By observing the analyzer, you can know whether the product is qualified. During the inspection process and when the equipment is not in use, slide the door panel downward, and the protective cover and the door panel protect the lower mold and the cylinder, thereby avoiding the situation where the upper mold cavity and the lower mold cavity in the current camera airtightness inspection equipment are directly exposed. When the equipment is not in use, a large amount of dust and particles will enter. During the inspection process, dust and particles may enter the camera, causing its performance to be affected.

[0007] Preferably, a dust suction pump is fixedly connected to the protective cover, and an input end of the dust suction pump is communicated with the protective cover; a collection box is fixedly connected to the equipment table, and an output end of the dust suction pump is communicated with the collection box.

[0008] The effect achieved by the above components is: before the detection, the dust suction pump can be started, and the dust suction pump can pump dust particles, wind and other impurities in the protective cover into the collection box, thereby improving the protection effect.

[0011] Preferably, a plurality of triangular blocks are fixedly connected to the door panel, a fixed plate is fixedly connected to the protective cover, a sliding rod is slidably connected to the fixed plate, a limiting block is fixedly connected to the sliding rod, and a first spring is sleeved on the sliding rod.

[0012] The effect achieved by the above components is that the lower surface of the triangular block contacts the upper surface of the limiting block, which can limit the door panel and prevent it from sliding down.

[0013] Preferably, one end of the first spring is fixedly connected to the limiting block, and the other end of the first spring is fixedly connected to the fixing plate.

[0014] The effect achieved by the above components is: when the door panel slides upward, the contact between the inclined surface of the triangular block and the inclined surface of the limit block will push the limit block to slide to the left, causing the first spring to contract. When the door panel continues to rise, the limit block will be stuck between the two triangular blocks under the action of the rebound force of the first spring, making the operation more convenient.

[0015] Preferably, a feeding structure is provided on the equipment table, and the feeding structure is mainly composed of two slide grooves, both of which are opened on the equipment table, and the two slide grooves are slidably connected to the lower mold.

[0018] The effect achieved by the above components is: after pushing the lower mold into the protective cover, the two round rods can be slid so that the two clamping blocks are clamped into the corresponding clamping grooves, thereby limiting the lower mold, making the position of the lower mold more accurate and improving the sealing of the lower mold and the upper mold.

[0019] Preferably, a rectangular plate is sleeved on the round rod, one end of the second spring is fixedly connected to the round rod, and the other end of the second spring is fixedly connected to the rectangular plate.

[0020] The effect achieved by the above components is: when the lower mold slides into the protective cover, it will push the inclined surfaces of the two blocks, causing the two blocks to slide to both sides. At this time, the second spring is in a contracted state, so when the slot contacts the block, the block is stuck into the corresponding slot under the action of the rebound force of the second spring, making the limiting operation more convenient.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are that, in the utility model, by setting a protective structure, during the detection process and when the equipment is not in use, the door panel is slid downward, and the protective cover and the door panel start to protect the lower mold and the cylinder. Before the detection, the dust suction pump can be started, and the dust suction pump can pump dust particles, wind and other impurities in the protective cover into the collection box to improve the protection effect. The first motor is started, and the output shaft of the first motor drives the gear to rotate, which can drive the rack to move up and down, making the operation of opening and closing the door panel more convenient. The lower surface of the triangular block contacts the upper surface of the limit block. The door panel can be limited to prevent it from sliding down. When the door panel slides upward, the contact between the inclined surface of the triangular block and the inclined surface of the limit block will push the limit block to slide to the left, causing the first spring to contract. When the door panel continues to rise, the limit block will be stuck between the two triangular blocks under the action of the rebound force of the first spring, making the operation more convenient, thereby avoiding the problem that the upper mold cavity and the lower mold cavity in the current camera airtight detection equipment are directly exposed, and a large amount of dust and particles will enter when the equipment is not in use. Dust and particles may enter the camera during the detection process, thereby affecting its performance. BRIEF DESCRIPTION OF THE DRAWINGS
