Description

Technical Field

[0001] This utility model relates to a testing device, and more particularly to a testing device suitable for testing the sealing performance of a control box. Background Technology

[0002] For existing wireless communication base stations, antenna equipment is distributed on the towers where they are located. During use, the antenna equipment needs to be adjusted in angle via a control box to ensure it is positioned at a suitable angle. During implementation, the control box is primarily located in outdoor environments. Therefore, it has high waterproofing requirements, and waterproofing testing is required during manufacturing.

[0003] Currently, the standard testing procedure for control boxes is as follows:

[0004] Close the control box lid. Tighten it with screws or other fittings to seal the control box and lid. Then, place the control box in a water tank, ensuring it is fully submerged. After a period of time, remove the control box, open the lid, and check the inside for water stains to assess the seal's effectiveness.

[0005] However, this testing method is time-consuming and often results in water splashing at the testing site, affecting the cleanliness of the testing station. Furthermore, improper handling during opening can cause residual water on the lid to drip into the control box, leading to false leak detections. Additionally, water can easily penetrate small joints and gaps, causing some leaks to be missed.

[0006] In view of the above-mentioned shortcomings, the designer has actively researched and innovated in order to create a testing device suitable for the sealing performance of control boxes, making it more valuable for industrial applications. Utility Model Content

[0007] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a testing device suitable for the sealing performance of control boxes.

[0012] Furthermore, in the aforementioned testing equipment for controlling the sealing of the box, the lifting bracket is a "Z"-shaped bracket, the top of the "Z"-shaped bracket supports the bottom of the air tube, and the bottom of the "Z"-shaped bracket is connected to the support platform.

[0013] Furthermore, in the aforementioned test equipment for controlling the sealing of the control box, the branch mechanism includes a branch valve, the input end of which is connected to an air pipe, the output end of which is connected to a pressure gauge, and the output end of which is connected to an outlet branch pipe assembly.

[0014] Furthermore, in the aforementioned testing equipment suitable for controlling the sealing of the box, the pressure gauge is either a mechanical gauge or an electronic gauge.

[0020] 2. No soaking is required, eliminating the need for subsequent cleaning of the control box and preventing the risk of water residue.

[0032] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0033] like Figure 1 The testing equipment for the control box sealing performance includes a support platform 1, which is unique in that: a positioning bracket 2 is installed on the support platform 1, and a gas inlet device is installed on the positioning bracket 2 to allow for overhead installation. Simultaneously, considering that the connecting air pipe 4 can also achieve an effective overhead layout, several lifting brackets 3 are distributed on the support platform 1, and air pipes 4 are installed on the lifting brackets 3, with the air pipes 4 connected to the gas inlet device. Furthermore, to enable simultaneous testing of multiple control boxes 12, several branch mechanisms are distributed on the air pipes 4, and each branch mechanism is connected to an independent outlet branch assembly 11. Moreover, auxiliary positioning components (not shown in the figure) are distributed on the support platform 1 at the outlet positions of the outlet branch assembly 11. This allows for limiting the control box 12 during testing, preventing it from sliding or affecting its airtightness after docking with the outlet branch assembly 11.

[0034] According to a preferred embodiment of this utility model, the supporting platform 1 includes a platform body with a plurality of mounting holes distributed on the platform body. This allows for pre-installation preparation of the positioning bracket 2, the lifting bracket 3, and the auxiliary positioning components, and enables installation and locking via screws as needed.

[0035] Furthermore, to achieve stable installation, the positioning bracket 2 includes a flat plate bracket perpendicular to the supporting platform 1. A locking ring 5 is screwed onto the flat plate bracket, and one side of the gas inlet device is connected to the locking ring 5. The locking ring 5 used is a conventional connecting ring structure or a clamp structure, which will not be described in detail here. During use, the alignment interface on one side of the gas inlet device is inserted into the locking ring 5 for locking. During implementation, the gas inlet device includes a water vapor separator 6 mounted on the positioning bracket 2. A main switch valve 7 is installed at the output end of the water vapor separator 6, and a pressure regulating valve 8 is installed at the output end of the main switch valve 7. The output end of the pressure regulating valve 8 is connected to the gas pipe 4. This satisfies the water vapor separation requirements after external gas inlet and provides a suitable gas output pressure.

[0036] In practical implementation, the lifting support 3 is a "Z"-shaped support. The top of the "Z"-shaped support supports the bottom of the air pipe 4, and the bottom of the "Z"-shaped support is connected to the bearing platform 1. This ensures stable bearing. Simultaneously, the branch mechanism used in this invention includes a branch valve 9, the input end of which is connected to the air pipe 4. Furthermore, to monitor the real-time air pressure in the outlet branch assembly 11, a pressure gauge 10 is connected to the output end of the branch valve 9, and the output end of the pressure gauge 10 is connected to the outlet branch assembly 11. During use, considering the user's reading habits, the pressure gauge 10 can be either mechanical or electronic. Moreover, a communication port can be configured for the electronic gauge to facilitate connection to the testing platform for data acquisition.

[0037] Looking further, the outlet branch pipe assembly 11 includes a branch pipe body, and the outlet end of the branch pipe body is provided with a docking clip (not shown in the figure). This allows the docking clip to be inserted into the detection port of the control box 12, achieving a stable connection and preventing improper leakage during testing, thus not affecting the actual test data. Furthermore, a sealing ring can be installed in the docking clip to improve the airtightness of the connection port.

[0038] Meanwhile, the auxiliary positioning component is a rectangular limiting frame. This allows small control boxes 12 to be embedded within the rectangular limiting frame for positioning. For larger control boxes 12, their bottom can be embedded on the outside of the rectangular limiting frame for positioning. Of course, during implementation, a suitable rectangular limiting frame can be selected based on the layout of the mounting holes. Thus, convenient positioning can be achieved for different types of control boxes 12.

[0039] Furthermore, to ensure a more stable layout with the desktop where the testing station is located, anti-slip pads (not shown in the figure) can be distributed at the bottom of the support platform 1.

[0040] The working principle of this utility model is as follows:

[0041] Cover the control box 12 with a lid to ensure a tight seal between the two components. Then, place the control box 12 onto the support platform 1, ensuring it is in contact with the auxiliary positioning assembly. Next, insert the mating clips of the air outlet branch pipe assembly 11 into the inspection port of the control box 12. (The inspection port is typically the wiring inlet for a subsequent sealing component and does not affect airtightness.)

[0042] Next, through the cooperation of branch valve 9 and main switch valve 7, a certain amount of test air pressure is introduced into the outlet branch pipe assembly 11.

[0043] Afterwards, after completing branch valve 9 and maintaining it for a certain period of time, check the actual pressure drop value through the corresponding pressure gauge 10 to determine whether the current control box 12 meets the corresponding sealing parameters.

[0044] Therefore, pressure changes can be viewed more intuitively without soaking, which shortens the testing time and eliminates the need for dehydration and cleaning.

[0045] As can be seen from the above textual description and the accompanying drawings, the present invention has the following advantages:

[0046] 1. The sealing effect is tested by air injection and changes in air pressure, which simplifies the testing process.

[0047] 2. No soaking is required, eliminating the need for subsequent cleaning of the control box and preventing the risk of water residue.

[0048] 3. It can simultaneously perform sealing tests on multiple control boxes, improving testing efficiency.

[0049] 4. It can be directly placed in the inspection station of the processing equipment without the need for a separate water tank.

They are only for the purpose of facilitating the description of this utility model and simplifying the description, and are not intended to indicate or imply that the device or structure referred to must have a specific orientation, or to operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
