Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterproof testing instruments, and in particular to a sealed waterproof testing chamber. Background Technology
[0002] In the field of waterproof testing instrument technology, waterproof test chambers are widely used for testing the waterproof performance of electronic, electrical, and automotive parts.
[0003] Existing waterproof test chambers typically use a one-time water filling method for spray testing. After the test, the water in the chamber is directly discharged, resulting in a significant waste of water resources, which contradicts the principles of energy conservation and environmental protection. Furthermore, the spray structure of these chambers is often fixed, and the spray height and position cannot be adjusted according to the size of the test items. When dealing with test items of different sizes, either the distance between the nozzle and the item is too close, leading to excessive test pressure and affecting the accuracy of the test results; or the distance is too far, resulting in insufficient test pressure and inadequate coverage, failing to meet the standard testing requirements. Therefore, we propose a sealed waterproof test chamber to solve this problem. Utility Model Content
[0004] The purpose of this invention is to provide a sealed waterproof test chamber to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A sealed waterproof test chamber includes: a test chamber body, an internal partition of the test chamber body, a water storage tank on the bottom inner wall of the test chamber body, a filter plate on the top of the water storage tank, a test platform on the top of the filter plate, a water inlet pipe connected to one side of the water storage tank, a water pump connected to the other side of the water storage tank, a connecting hose connected to the outlet of the water pump, and two sets of screws rotatably mounted on the top of the test chamber body. Threaded sleeves are threadedly connected to the outer sides of both sets of screws, and the bottoms of the two sets of threaded sleeves are fixed. A U-shaped frame is fixedly installed, and a lifting rod is fixedly installed between the top of the U-shaped frame and the top inner wall of the test chamber body. A U-shaped spray pipe is installed inside the U-shaped frame, and multiple spray nozzles are connected to the outside of the U-shaped spray pipe. Two sets of brackets are fixedly installed on the top of the test chamber body. A rotating shaft is rotatably installed inside the two sets of brackets. A driving bevel gear is fixedly installed on the outside of the two sets of rotating shafts. A driven bevel gear is fixedly installed on the top of the two sets of screws. A closed door is hinged to one side of the test chamber body, and a viewing window is provided inside the closed door.
[0007] Preferably, a round rod is rotatably installed inside the closed door. A round plate and a handle are fixedly installed on the outer side and one end of the round rod, respectively. Two sets of support rods are hinged to one side of the round plate. Two sets of L-rods are slidably installed inside the closed door. The two sets of support rods are hinged to the corresponding L-rods. The two sets of L-rods are slidably installed inside one side of the closed door. Four sets of universal wheels are provided at the bottom of the test chamber body. A controller is provided on one side of the test chamber body to reduce manual intervention, improve testing efficiency, and reduce the risk of operational errors.
[0008] Preferably, the U-shaped spray pipe is connected to the connecting hose, and the water inlet pipe is located on one side of the test chamber body to ensure that the nozzle sprays water continuously and stably during the test and avoids interruption of the test due to lack of water.
[0009] Preferably, the partition has a sliding groove inside, the connecting hose is slidably installed in the sliding groove, and two sets of L-shaped locking grooves are opened inside one side of the test chamber body. One end of the two sets of L rods is slidably installed in the corresponding L-shaped locking grooves, which enhances the sealing effect and facilitates quick unlocking, combining stability and convenience.
[0010] Preferably, a drive motor is fixedly installed on one side of one of the brackets, and one end of the rotating shaft is fixedly installed on the output end of the drive motor, so as to realize the smooth lifting and lowering of the U-shaped spray pipe and avoid shaking that affects the test accuracy.
[0011] Preferably, the interior of the closed door has a square groove, and both sets of support rods and circular plates are set in the square groove, which improves the transmission efficiency of the door lock structure and makes the opening and closing operation easier and smoother.
[0012] In this utility model, a sealed waterproof test chamber is equipped with casters to move the equipment to a designated position, which greatly improves the flexibility of equipment use. It is especially suitable for working environments that require frequent changes of test locations or multi-scenario testing, reducing the cost and difficulty of manual handling. The setting of a viewing window allows the operator to observe the waterproof test status of the items inside the test chamber in real time without opening the closed door, avoiding damage to the sealed environment due to frequent opening of the chamber, which would affect the accuracy of the test results.
[0013] In this utility model, a sealed waterproof test chamber is provided. By setting a handle to drive the round rod and the round plate to rotate, the two sets of support rods swing in the square groove. Then, through the hinge between the support rod and the L-rod, the two sets of L-rods slide inside the closed door. The L-rod is then located at the unlocking position of the L-shaped locking groove of the test chamber body, thereby unlocking the closed door. By pulling the handle, the closed door can be opened, and the test item can be placed on the test table. Then, the closed door can be closed. Rotating the handle in the opposite direction moves the L-rod away, closing the closed door and locking it to form a sealed test space. The operator can easily and quickly complete the opening and closing of the door, greatly reducing the preparation time before the test. This simple and efficient operation method can significantly improve work efficiency and reduce the labor intensity of the operator.
[0014] This utility model features a reasonable structural design. It incorporates a drive motor, a rotating shaft, a support frame, and two sets of active and driven bevel gears. The meshing of the active and driven bevel gears drives the corresponding screws to rotate synchronously. A threaded connection between the screws and a threaded sleeve allows the threaded sleeve to move the U-shaped frame up and down under the guidance of a lifting rod. The U-shaped spray pipe extends the connecting hose and slides within the partition, accommodating test objects of different sizes. Water is added to the storage tank through the inlet pipe, and then the water pump is activated. Water is transported from the storage tank through the inlet pipe and connecting hose to the U-shaped spray pipe, spraying the test objects through the nozzles. The sprayed water is filtered through a filter plate before returning to the storage tank, reducing water waste. Furthermore, by adjusting the spray height to maintain a suitable distance between the nozzle and the test object for different sizes, the test pressure and coverage meet standards. This significantly expands the applicability of the test chamber, improves the equipment's versatility, reduces manpower, and shortens test preparation time. Attached Figure Description
