Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4 This utility model proposes an air intake rod assembly 200.

[0025] The gas sampling rod assembly 200 includes a mounting plate 300, a gas sampling rod 220, and a mounting block 230. The mounting plate 300 is used to fix it to the battery testing equipment. The gas sampling rod 220 has a gas channel inside, with openings at both ends. One end of the gas channel is for connecting to an air pump device, and the other end is for connecting to the air intake port 110 of the negative pressure cleaning fixture. The mounting block 230 includes a first mounting block 231 and a second mounting block 232. The first mounting block 231 is disposed on the mounting plate 300 and has a first splicing groove 233. The second mounting block 232 has a second splicing groove 234 corresponding to the first splicing groove 233. The first mounting block 231 and the second mounting block 232 are spliced ​​together so that the first splicing groove 233 and the second splicing groove 234 can clamp the gas sampling rod 220.

[0026] Specifically, the air intake rod assembly 200 is installed in the test module of the battery testing equipment and descends with the test module, so that one opening of the air intake rod 220 can be connected to the air intake port 110 of the negative pressure cleaning fixture, the air vent 120 is connected to the negative pressure pipeline of the negative pressure cleaning fixture, and the other opening of the air intake rod 220 is connected to an air pump device to provide power for the cleaning fluid of the negative pressure cleaning fixture to flow in the negative pressure pipeline, thereby completing the cleaning process. The air intake rod assembly 200 consists of an air intake rod 220 and upper and lower mounting blocks 231 and 232. During assembly, the air intake rod 220 is first placed into the first splicing groove 233 of the first mounting block 231 or the second splicing groove 234 of the second mounting block 232. Then, the first mounting blocks 231 and 232 are joined together, pressing the air intake rod 220 into them. Finally, the first mounting blocks 231 and 232 can be connected and fixed together using threaded connections or other methods to complete the assembly. This design makes the assembly of the air intake rod assembly 200 simple and convenient, significantly reducing manufacturing costs.

[0027] Please see Figures 1 to 3 Furthermore, the first mounting block 231 has first locking blocks 235 on both sides within the first splicing groove 233, and the second mounting block 232 has second locking blocks 236 on both sides within the second splicing groove 234. The outer peripheral wall of the air-taking rod 220 has recessed grooves 221 on both sides. The first locking blocks 235 on both sides are respectively engaged with one side of the grooves 221 on both sides, and the second locking blocks 236 on both sides are engaged with the other side of the grooves 221 on both sides. Thus, the grooves 221 machined on the air-taking rod 220, in conjunction with the shapes of the first locking blocks 235 of the first mounting block 231 and the second locking blocks 236 of the second mounting block 232, limit the air-taking rod 220 in one or more directions. This easily and conveniently achieves the rigidity requirements of preventing the air-taking rod 220 from moving or rotating, ensuring the stability of the air-taking rod 220 connected to the air-taking port 110 of the tooling air-taking component 100.

[0028] Please see Figures 1 to 3 To improve assembly efficiency, the first mounting block 231 is further provided with multiple positioning holes 250, and the second mounting block 232 is provided with multiple positioning posts 240, which can be inserted into the positioning holes 250. By pre-positioning the positioning posts 240 into the positioning holes 250, the accuracy of the positioning position is ensured, thereby improving the assembly efficiency of the first mounting block 231 and the second mounting block 232.

[0029] Please see Figures 1 to 3Furthermore, the first mounting block 231 is provided with a first screw hole 237, and the second mounting block 232 is provided with a second screw hole 238. The first mounting block 231 and the second mounting block 232 are screwed together through the first screw hole 237 and the second screw hole 238. In this way, after the first mounting block 231 and the second mounting block 232 are assembled, bolts are used to screw the first mounting block 231 and the second mounting block 232 together through the first screw hole 237 and the second screw hole 238, which greatly reduces the manufacturing cost.

[0030] Please see Figures 1 to 3 Furthermore, the first mounting block 231 and the second mounting block 232 are made of plastic molded parts. Compared with traditional metal block cutting and processing, the first mounting block 231 and the second mounting block 232 made of plastic can effectively reduce production costs and facilitate the formation of the first locking block 235 and the second locking block 236.

[0031] Please see Figures 1 to 3 Furthermore, the air intake rod 220 has an air intake end 260, which is used to insert into the air intake port 110 of the negative pressure cleaning fixture. The diameter of the air intake end 260 gradually decreases in the direction away from the mounting block 230. This improves the smoothness of the insertion of the air intake rod 220 into the air intake port 110 of the negative pressure cleaning fixture, ensuring that the air intake rod 220 can be connected to the air intake port 110 of the negative pressure cleaning fixture.

[0032] Please see Figures 1 to 4 This utility model also proposes a negative pressure cleaning fixture air intake mechanism, which includes an air intake rod assembly 200 and a fixture air intake component 100. The fixture air intake component 100 has an air intake port 110 and an air vent 120. The air intake port 110 is connected to one end opening of the air intake rod 220, and the air vent 120 is used to connect to the negative pressure pipeline of the negative pressure cleaning fixture. The specific structure of the air intake rod assembly 200 is as described in the above embodiments. Since this negative pressure cleaning fixture air intake mechanism adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be described in detail here.

[0033] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. All equivalent structural transformations made based on the contents of this utility model specification and drawings under the utility model concept, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
