detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figures 1 to 4, it is a preferred embodiment of the silent test room of the present utility model. The conveying device 3 for conveying the product under test and the power socket 4 for plugging into the plug 10 of the product under test. Specifically, the front door 1 and the rear door 2 are oppositely arranged, the side door is located between the front door 1 and the rear door 2 , and the delivery device 3 and the power socket 4 are both located in the testing room 5 . The above-mentioned silent test room also includes an automatic shedding device 7 installed in the test chamber 5, and the power socket 4 is telescopically installed on the automatic shedding device 7, and the automatic shedding device 7 is equipped with a plug 10 that can make the product under test be removed from the power supply. The baffle plate 74 that comes off on the socket 4. After the plug 10 of the product under test is plugged on the power socket 4, the plug 10 of the product under test can be pulled out from the power socket 4 by the contraction of the power socket 4 installed on the automatic shedding device 7, and the There is no need to open the side door to extend the head and shoulders into the test chamber 5 to pull out the plug 10 of the product under test, which saves a lot of time and improves the test efficiency.

In the above embodiments, the automatic shedding device 7 includes a telescopic cylinder 73 and a fixing frame 72 . The fixed frame 72 is installed in the test chamber 5, the telescopic cylinder 73 is installed on the fixed frame 72, and the power socket 4 is installed on the piston rod of the telescopic cylinder 73, which is driven by the telescopic cylinder 73 to expand and contract.

The silent test room above also includes a mobile actuator 6 installed in the test chamber 5 , and the mobile actuator 6 includes a control motor 61 , a motor mounting plate 62 , a gear 63 , a rack 64 and a rail base 65 . The rack 64 is fixedly installed on the guide rail base 65 , and the extension direction of the guide rail base 65 and the rack 64 is parallel to the transporting direction of the conveying device 3 . The automatic shedding device 7 is fixedly installed on the motor mounting plate 62 through a fixed connection plate 71 . The motor mounting plate 62 is slidably connected to the guide rail base 65 , the control motor 61 is mounted on the motor mounting plate 62 , and its output shaft is connected to the gear 63 , and the gear 63 and the rack 64 are meshingly connected. In this way, the control motor 61 drives the gear 63 to rotate, and the gear 63 rolls on the rack 64, thereby driving the motor mounting plate 62 to move between the front door 1 and the rear door 2, and then driving the power socket 4 to move to the front door 1 by fixing the connecting plate 71 , so that the operator can insert the plug 10 of the product under test into the power socket 4 at the front door 1 . The working principle of the above-mentioned mobile actuator 6 driving the power socket 4 to move can also be completed by other pneumatic components and pneumatic guide rails in other embodiments, as long as the power socket 4 can be automatically driven to the front door.

In the above embodiment, both ends of the rack 64 are provided with buffer seats for restricting the movement of the moving actuator 6 . In this way, when the gear 63 rolls forward or backward on the rack 64, when the gear 63 rolls to either end of the two ends of the rack 64, the buffer seat 8 plays a role of buffering and preventing the rolling of the gear 63.

Please refer to FIG. 5 to FIG. 7 together, the plug 10 of the product under test includes a plug body 20 and an insert 30 fixed on the plug body 20 . One side of the fixing frame 72 has a first notch 721 , and a baffle plate 74 for blocking the plug body 20 is mounted thereon. A second notch 741 corresponding to the power socket 4 and the first notch 721 is defined on the baffle plate 74 , and the opening end of the second notch 741 faces downwards, allowing the insertion piece 30 to pass through. When the plug 10 of the product under test is plugged into the power socket 4 , the baffle 74 can block the plug body 20 . In this embodiment, the shape of the second notch 741 on the baffle 74 is convex. In other embodiments, the shape of the second notch 741 can also be in various shapes, as long as the insertion piece 30 of the product under test can pass through, but the plug body 20 cannot pass through.

In summary, the working process of the utility model embodiment is as follows:

Firstly, the moving actuator 6 drives the fixed connection plate 71 to drive the automatic shedding device 7 installed with the power socket 4 to move in the direction of the front door 1, and the front door 1 is opened. The operator stands at the front door 1 and inserts the plug 10 of the product under test into the power supply. on socket 4. After the insertion is completed, the product under test is transported to the test chamber 5 by the delivery device 3 for a silent test. After the test is completed, the power socket 4 is controlled by the telescopic cylinder 73 to shrink. At this time, due to the effect of the baffle plate 74, the energy will be The plug body 20 of the test product is blocked, and because the opening end of the second notch 741 on the baffle plate 74 is downward. Therefore, after the plug 10 of the test product can be pulled out from the power socket 4 through the contraction of the power socket 4, the plug 10 will fall from the second gap 741 on the baffle plate 74 under the action of gravity, without manual labor from the side door. Put your head and shoulders into the silent test chamber 5 to pull out the plug 10 of the product under test. Finally, the rear door 2 is opened, and the tested product that has been tested is transported out through the conveying device 3 . During the above process, the side door can always remain closed.

The advantage of the above-mentioned silent test room is that the operator does not need to open the side door to extend his head and shoulders into the silent test room to perform the work of pulling out the plug of the product under test. On the one hand, it reduces the workload of the operator and saves time. The test efficiency is improved; on the other hand, the operator's operation safety is greatly improved.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
