Description

Technical Field

[0001] This utility model relates to the field of water pump testing technology, and more specifically, to a portable electronic water pump testing machine. Background Technology

[0002] Currently, factories test the complete performance of electronic water pumps after completion. However, the equipment used is large-scale automated testing equipment that is generally immobile, which is very different from the portability emphasized in this solution. Therefore, a portable electronic water pump testing machine is needed.

[0003] Among the existing publicly available technical documents, Chinese Patent Publication No. CN215762177U discloses an automatic performance testing device for recovering engine electronic water pumps. This technology utilizes the interplay of a connecting mechanism consisting of a fixing plate, a fixing seat, a sealing ring, a limiting plate, a rotating frame, and internal and external threads to achieve an efficient and convenient connection between the test tube and the test water pump, improving the device's efficiency during use. Simultaneously, the use of the sealing ring ensures a better seal at the connection between the test tube and the test water pump, reducing leakage and improving test accuracy, thus significantly enhancing the device's practicality. However, this portable electronic water pump testing machine still has the following drawbacks during use.

[0004] When using a portable electronic water pump tester, the test terminals need to be connected to the electronic water pump via a connecting cable to perform voltage testing on the electronic water pump. However, after connection, the connecting cable is long, and the connected terminals are difficult to quickly locate and store, making it more time-consuming and laborious to carry the electronic water pump tester.

[0010] In this technical solution, a transmission motor drives a transmission screw to rotate, while the sleeve block moves to the left along the inner wall of the support plate, and the connecting column causes the limiting plate to move to the left synchronously. The support bar drives two arc-shaped pressure strips to move to the left synchronously, and the two arc-shaped pressure strips press against the top of the outer wall of the two test heads respectively, achieving the limiting and fixing operation.

[0020] 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.

[0021] As attached Figure 1-5 The portable electronic water pump tester shown is equipped with a positioning and storage mechanism. The positioning and storage mechanism can quickly store the two test heads 3 and the two connecting wires 2 in the extra space inside the tester body 1, making the tester body 1 easy to carry and use. The specific structure of the positioning and storage mechanism is as follows.

[0022] In this technical solution, as shown in the appendix Figure 1-3As shown, two connecting lines 2 are fixedly connected to one side of the test body 1. A test head 3 is fixedly connected to one end of each connecting line 2. The outer wall of the test head 3 is provided with a positioning and storage mechanism. The positioning and storage mechanism includes an arc-shaped locking strip 4 that is snapped onto the outer wall of the test head 3. A support plate 5 is installed at the bottom end of the arc-shaped locking strip 4. Both arc-shaped locking strips 4 are fixedly connected to the support plate 5. A linkage plate 6 is fixedly connected to one side of the support plate 5. A threaded sleeve 7 is fixedly connected to one end of the linkage plate 6. A screw 8 is threadedly connected to the inner wall of the threaded sleeve 7. A storage motor 9 is fixedly installed on one side of the inner wall of the test body 1. The storage motor 9 is used to drive the screw 8 to rotate.

[0023] The test unit 1 is model BJJSY-10.

[0024] In this technical solution, as shown in the appendix Figure 1 As shown, a display screen 10 is fixedly installed on the other side of the test body 1, and two buttons 11 fixedly connected to the test body 1 are provided on one side of the display screen 10; a plug 12 fixedly connected to the test body 1 is provided on the other side of the display screen 10, so that the test body 1 can be powered by the plug 12, and the test voltage value can be displayed on the display screen 10 when the button 11 is pressed.

[0025] In this embodiment, when using the portable electronic water pump tester, first remove the two test heads 3 from inside the arc-shaped retaining strip 4, and then insert the two test heads 3 into the two test ends of the electronic water pump. The tester body 1 is powered by the plug 12, and the button 11 is pressed to display the test voltage value on the display screen 10. The tester body 1 is then connected to the test heads 3 via the connecting cable 2, and the two test heads 3 perform the test operation on the electronic water pump. After the test of the electronic water pump is completed, the tester body 1 needs to be transported.

[0026] By inserting the test head 3 into the inner wall of the arc-shaped retaining strip 4, the arc-shaped retaining strip 4 engages the test head 3, while two arc-shaped pressure strips 18 press against the upper part of the outer wall of the test head 3. Simultaneously, the storage motor 9 is activated to drive the screw 8, which in turn drives the threaded sleeve 7 to move to the left under the force of the threaded transmission. At the same time, the threaded sleeve 7 drives the linkage plate 6 to move to the left into the testing body 1, and the linkage plate 6 drives the support plate 5 to move to the left. The support plate 5 causes the arc-shaped retaining strip 4 to move to the left, which in turn drives the test head 3 to move to the left. The test head 3 then moves the connecting wire 2, allowing both test heads 3, each carrying one connecting wire 2, to enter the testing body 1. This allows for quick and easy storage of the two test heads 3 and the two connecting wires 2 inside the testing body 1, enabling the testing body 1 to be easily moved.

[0027] In this technical solution, as shown in the appendix Figure 4-5As shown, a limiting assembly is installed on the inner wall of the test body 1. The limiting assembly includes a drive motor 13 fixedly installed on the inner wall of the test body 1, a drive screw 14 fixedly connected to the output end of the drive motor 13, a threaded connection sleeve block 15 on the outer wall of the drive screw 14, and a connecting post 16 fixedly installed at the top of the sleeve block 15. A limiting plate 17 is fixedly connected to the top of the connecting post 16. Two arc-shaped pressure strips 18 are fixedly connected to the inner wall of the limiting plate 17, and a support strip 19 is fixedly installed on the upper surface of the limiting plate 17. The drive motor 13 drives the drive screw 14 to rotate, and the drive screw 14 is rotatably connected to the support plate 5. The sleeve block 15 is slidably connected to the support plate 5, and the vertical cross-section of the two arc-shaped pressure strips 18 is arc-shaped.

[0028] In this embodiment, the transmission screw 14 is driven to rotate by the transmission motor 13. The transmission screw 14 carries the sleeve block 15 and moves it to the left under the action of the thread transmission force. At the same time, the sleeve block 15 moves to the left along the inner wall of the support plate 5, and the sleeve block 15 drives the connecting post 16 to move to the left. The connecting post 16 causes the limiting plate 17 to move to the left in sync. The limiting plate 17 causes the support bar 19 to move to the left, and the support bar 19 drives the two arc-shaped pressure strips 18 to move to the left in sync. The two arc-shaped pressure strips 18 are pressed against the top of the outer wall of the two test heads 3, so that the arc-shaped pressure strips 18 firmly limit the test heads 3.
