Description

Technical Field

[0001] The utility model relates to the technical field of shielding boxes, in particular to a shielding box used for product aging testing. Background Art

[0002] The RF functional test adopts a test process that is run in parallel by multiple identical test stations. By using a shielding box, it is possible to better fully test the different needs of the product, and it is also possible to obtain test data when the product is aged, thereby ensuring the availability of the product.

[0003] In the prior art, a Chinese patent with authorization announcement number CN211785696U discloses a signal shielding box for testing, which includes: a box body with an opening on the front side, a box door hinged on the opening of the box body, a sponge layer on the inner wall of the box door, a heat sink and a heat dissipation motor on the side panel of the box body, a power socket and a communication interface on the box body, the power socket is located on the inner and outer sides of the box body and has a plug hole, and the communication interface is located on the inner and outer sides of the box body and has a communication interface. Compared with the prior art, the signal shielding box for testing of the utility model forms a closed signal shielding detection space through a metal box body and a box door, thereby isolating external base station signals, reducing signal interference from adjacent test benches and the influence of operators, thereby integrating the test process, simplifying the process, and making the test more accurate and reliable.

[0004] The above mechanism forms a closed signal shielding detection space through a metal box and door, thereby simplifying the process and making the test results more accurate. However, in actual use, the shielding box must not only ensure that the interior is not interfered by external electromagnetic signals, but also ensure its own internal ventilation performance. When the internal ventilation performance is poor, the temperature of the components used inside will rise, and the temperature cannot be dissipated, affecting the service life of the internal components. Utility Model Content

[0005] The utility model aims to provide a shielding box for product aging testing to solve the problem in the above background technology that poor ventilation performance causes the temperature of internal components to rise, thereby affecting the service life of the internal components.

[0007] Three waveguide windows are arranged on both sides of the shielding box body, and cleaning mechanisms for cleaning dust from the gaps of the waveguide windows are arranged on both sides of the shielding box body on one side of the waveguide window, the cleaning mechanism comprises a mounting plate, and the mounting plate is fixedly connected to the upper end and the lower end of both sides of the shielding box body, one side between the mounting plates is fixedly connected to a threaded rod, one side of the mounting plate is fixedly connected to a driving motor, and the output end of the driving motor is connected to the threaded rod;

[0008] A placing rack is slidably connected inside the shielding box body, and a partition mechanism for separating products is arranged on the placing rack.

[0009] Furthermore, a movable block is sleeved on the outer side of the threaded rod, and a cleaning brush is fixedly connected to one end between the movable blocks, one side of the cleaning brush is in contact with the outer side of the waveguide window, and a pulley is sleeved on the outer side of the threaded rod.

[0010] Furthermore, a collection mechanism for collecting dust is provided under the threaded rods on both sides of the shielding box body, and the collection mechanism includes a mounting frame, and the mounting frame is fixedly connected to the bottom of the threaded rods on both sides of the shielding box body, and a collection box is snap-connected on one side between the mounting frames.

[0011] Furthermore, a brush is fixedly connected to the bottom end of the movable block, and the bottom end of the brush fits with the bottom end of the inside of the collection box.

[0012] Furthermore, the bottom end of the collection box is provided with ash dropping grooves, and the ash dropping grooves are evenly spaced and distributed at the bottom end of the collection box.

[0013] Furthermore, the separation mechanism includes separation rods, and the separation rods are distributed at the top of the placement rack, and the product to be tested is clamped on one side between the separation rods.

[0014] Furthermore, the partition rods are evenly spaced and distributed on the top of the placement rack, and the partition rods are symmetrical about the central axis of the placement rack in the horizontal direction.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. By driving the output end of the motor to rotate, the threaded rod can be driven to rotate, so that the threaded rod can drive the movable block to move left and right. At the same time, the threaded rod can also drive the pulley on one side to rotate, so that the two threaded rods rotate synchronously, and then the cleaning brush can move left and right smoothly. The cleaning brush continuously rubs on the surface of the waveguide window, thereby cleaning the dust in the gap of the waveguide window and reducing dust accumulation;

[0017] Furthermore, the waveguide window can ensure ventilation inside the shielding box body when the shielding box body is in use, and can effectively avoid leakage of electromagnetic waves inside the shielding box body, and can also prevent external signals from causing signal interference to the product to be tested inside, and can effectively assist the device to perform long-term stable operation;

[0018] Furthermore, when the movable block moves, it will drive the brush to move left and right, and the fallen dust will be collected inside the collection box. The left and right movement of the brush will move the dust accumulated inside the collection box so that the dust will not stick to the bottom of the collection box.

By providing multiple partition rods, it is convenient to stably separate the products to be tested under different requirements, and the partition rods can prevent the products to be tested from being stacked together to affect the test results;

[0020] Furthermore, the handle on the surface of the shielding door can be used to stably close the shielding door when in use, avoiding the situation where the shielding door is not closed tightly during use. At the same time, the mutual cooperation between the buckle seat and the handle can make the overall stability of the shielding box body during use higher. BRIEF DESCRIPTION OF THE DRAWINGS

By driving the output end of the motor 8 to rotate, the threaded rod 10 can be driven to rotate, so that the threaded rod 10 can drive the movable block 11 to move left and right. At the same time, the threaded rod 10 can also drive the pulley 13 on one side to rotate, so that the two threaded rods 10 rotate synchronously, and then the cleaning brush 12 can move left and right smoothly. The cleaning brush 12 continuously rubs on the surface of the waveguide window 2, thereby cleaning the dust at the gap of the waveguide window 2 and reducing dust accumulation.

[0033] Embodiment 2:

[0034] like Figure 1-Figure 5 The technical solution shown is based on Example 1, in order to solve the problem that the dust will be blown out by the fan arranged inside the waveguide window 2 after being swept, causing the dust to scatter and affecting the working environment: the shielding box used for product aging testing discloses a collecting mechanism, and a collecting mechanism for dust collection is arranged under the threaded rods 10 on both sides of the shielding box body 1, and the collecting mechanism includes a mounting frame 17, and the mounting frame 17 is fixedly connected to the bottom of the threaded rods 10 on both sides of the shielding box body 1, and a collecting box 14 is clamped and connected on one side between the mounting frames 17, and a brush 15 is fixedly connected to the bottom end of the movable block 11, and the bottom end of the brush 15 is in contact with the bottom end of the collecting box 14, and a dust dropping groove 16 is provided at the bottom end of the collecting box 14, and the dust dropping grooves 16 are evenly spaced and distributed at the bottom end of the collecting box 14.
