Detailed implementation manners

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 4 , the present utility model provides an implementation solution: when performing environmental reliability tests on electrical appliances, it is often necessary to configure a variety of functional modules 4 on the test chamber 1. However, when in use, the various functional modules 4 provided on the test chamber 1 are not only complex in structure, inconvenient to manage and use, but also not easy to maintain, and not convenient to disassemble and replace during maintenance.

[0024] In view of the above problems, the present application discloses an electrical appliance environmental reliability test device, including a test chamber 1. The test chamber 1 is a hollow shell with a rectangular structure. A plurality of mounting grooves 2 are provided on the test chamber 1. The plurality of mounting grooves 2 are all rectangular groove structures, and a plurality of test structures with different functions are assembled on the plurality of mounting grooves 2;

[0025] In the specific implementation process, the test chamber 1 is used as the main body of the device for detecting environmental reliability. A switch door is provided on one side of the test chamber 1. The electrical appliance to be detected can be stored and retrieved through the switch door. By providing test structures on the plurality of mounting grooves 2, the functional types of the test structures can be disassembled and replaced as needed. A locking quick-connection component 5 is provided between the mounting groove 2 and the functional structure to facilitate the quick disassembly and replacement of the test structures with different functions;

[0026] According to the attached Figures 1 - 4 to the specification, the above test structure includes a test frame 3. The test frame 3 is a frame with a rectangular structure. A functional module 4 is installed inside the test frame 3. The functional module 4 is connected to the test frame 3 by screws. In the specific implementation process, the test frame 3 can be matched and connected with the mounting groove 2, and then two pairs of locking quick-connection components 5 are provided at the four corners of the test frame 3 to be locked and connected with the mounting groove 2 to prevent the test frame 3 from falling off. Different functional modules 4 are added to the test frame 3 as needed to perform different functions;

[0027] According to the attached Figures 1 - 4It can be seen that the above-mentioned locking quick-connection component 5 includes a locking rod 51. A locking groove is provided on the test frame 3, and the locking rod 51 is inserted into the locking groove. A fixing sleeve 52 is sleeved outside the locking rod 51. A return spring 53 is arranged inside the fixing sleeve 52. The return spring 53 is clamped with the locking rod 51. A pressing knob 54 is arranged at the top of the locking rod 51. A rotating rod 55 is connected to the pressing knob 54. The bottom end of the rotating rod 55 is an arc-lacking circle. A plurality of telescopic clamping rods 56 are arranged on the locking rod 51. A clamping hole 57 corresponding to the clamping rod is arranged in the clamping groove 6;

[0028] In the specific implementation process, through the cooperation of the locking rod 51 and the locking groove, the locking rod 51 passes through the locking groove and faces the installation groove 2. The fixing sleeve 52 outside the locking rod 51 plays a role in guiding and limiting the locking rod 51. The return spring 53 inside the fixing sleeve 52 can push the locking rod 51 backward. When locking, by pressing the pressing knob 54, the pressing knob 54 drives the locking rod 51 to move downward, so that the bottom end of the locking rod 51 moves to the telescopic clamping rod 56 and synchronously compresses the return spring 53. After the bottom end of the rotating rod 55 moves in place, by rotating the pressing knob 54, the rotating rod 55 rotates, and the non-arc-lacking part pushes the telescopic clamping rod 56, so that the telescopic clamping rod 56 is inserted into the clamping hole 57, playing a role in limiting the locking rod 51.

[0029] As a preferred solution, further, a pair of lifting handles are arranged at both ends of the test frame 3, which is convenient for lifting the test structure.

[0030] As a preferred solution, further, the types of the functional modules 4 include but are not limited to an air supply module 41, a water supply module 42, and a salt spray supply module 43, providing different wind direction and wind pressure environments, different rain environments, and salt spray environments.

A ventilation slot is opened on the fan frame, and an axial flow fan is assembled in the ventilation slot. Through the influence of the ventilation slot, the air generated by the axial flow fan can enter the test chamber 1, and the wind direction is controlled by changing the outlet direction;

[0032] The above water supply module 42 includes a bearing water tank, which is assembled on the test frame 3. A spray pump is arranged on one side of the bearing water tank and is communicated with the bearing water tank. A water supply pipe is connected to the spray pump, and a shunt spray plate is connected to the water supply pipe. Through the connection between the spray pump and the bearing water tank, the water in the bearing water tank is pumped into the water supply pipe by the spray pump, pumped into the shunt spray plate by the water supply pipe, and the shunt function of the shunt spray plate is used to spray the electrical appliance to simulate rain;

[0033] The above salt spray module 43 includes an atomizing water tank. One side of the atomizing water tank is connected to an atomizer. A number of atomizing nozzles are arranged on the atomizer and connected to the lower part of the atomizing water tank. One side of the atomizer is connected to a salt adding tank. Salt is added into the atomizer through the salt adding tank, water is introduced into the atomizer through the atomizing water tank, the water and salt are mixed, and after being atomized by the atomizer, the salt spray is introduced into the test chamber 1.

[0034] As a preferred solution, furthermore, the locking rod 51 is a cylindrical cavity rod, and the rotating rod 55 is inserted into the cavity of the locking rod 51. Through the dimensional matching between the locking rod 51 and the rotating rod 55, the guiding effect on the rotating rod 55 is realized.

[0035] As a preferred solution, furthermore, the return spring 53 is sleeved outside the locking rod 51. A limiting plate is sleeved on the rotating rod 55 and connected to the end of the return spring 53. The return spring 53 can play a role in resetting the locking rod 51. After the locking rod 51 is reset, the rotating rod 55 is pushed back to its original position by the reverse push of the return spring 53.

[0036] As a preferred solution, furthermore, a small spring is arranged between a number of telescopic clamping rods 56 and the locking rod 51 for the reset of the telescopic clamping rods 56.

[0037] Generally speaking, in the electrical environmental reliability test equipment, through the installation groove 2 as the installation position of different functional modules 4, different test effects can be achieved through different functional modules 4. Furthermore, through the locking quick-connection assembly 5, different functional modules 4 can be quickly disassembled and assembled, which is convenient to use. Different usage methods can be adjusted according to needs. While maintaining functionality, when not in use, the unused functional modules 4 can be disassembled and replaced, which is convenient for maintenance and can avoid damage caused by long-term idleness.
