These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the relevant components of the present invention.

[0018] According to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the entirety of the present invention or as a limitation or restriction to the technical solution of the present invention.

[0019] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Embodiment 1 and 2, as Figure 1 As shown, a test device for a variety of fixed barcode readers includes a base plate 1, an adjustment shaft 3, a movable slider 4, an up and down fine-tuning mechanism 6, and a fixed locking mechanism 7. The adjustment shaft 3 is installed on the top side of the base plate 1. The adjustment shaft 3 is slidably connected with the movable slider 4, can be slid manually, and is fixed at a certain height by a locking screw on the side. The movable slider 4 is fixedly connected with the up and down fine-tuning mechanism 6 through a cable fixing block 5. When the movable slider 4 moves, it drives the up and down fine-tuning mechanism 6 to move together.

[0021] The up-down fine-tuning mechanism 6 mainly plays the role of fine-tuning, and fine-tunes the height to adapt to the fixed barcode readers of different models. The up-down fine-tuning mechanism 6 is connected to the fixed locking mechanism 7 in a vertical direction, and the fixed locking mechanism 7 clamps and fixes the fixed barcode reader in the horizontal direction. The fixed barcode reader has a fixed shape relative to other barcode readers, so as to facilitate the clamping of the fixed locking mechanism 7.

[0022] A test mainboard 8 connected to the upper and lower fine-tuning mechanism 6 and the fixed locking mechanism 7 through cables is installed at the bottom of the base plate 1. The test mainboard 8 uses cables to control the upper and lower fine-tuning mechanism 6 and the fixed locking mechanism 7 to perform corresponding actions.

[0023] During implementation, the adjustment shaft 3 is fixed to the bottom plate 1 with screws, and the cable fixing block 5 is fixed to the moving slider 4 with screws. The up and down fine-tuning mechanism 6 is fixed to the cable fixing block 5 with screws, and the product fixing locking mechanism 7 is fixed to the up and down fine-tuning mechanism 6 with screws. The overall fixed structure is sleeved on the adjustment shaft 3 through the moving slider 4, and adjusted to the required height, and the locking screws on the side of the moving slider 4 are tightened. The test mainboard 8 is fixed to the back of the floor 1 with screws, and finally, different cables are connected according to the different products to be tested to realize the testing of different fixed barcode reader products.

[0024] Through this test device, the height can be freely adjusted, and the movable slider 4 can move up and down on the adjustment shaft 3 to adjust the height of the tested device from the bottom plate 1. The fixed locking mechanism 7 can adjust different widths to adapt to the widths of various fixed barcode readers and perform tightening clamping actions. Through this test device, it can bring great convenience to the test staff when testing various fixed barcode readers.

[0025] Example 2, based on Example 1, please refer to Figure 3Specifically, in order to install the cables and clamp them, a plurality of first cable clamps 11 for clamping the cables are installed at the bottom of the base plate 1, and a plurality of second cable clamps 51 for clamping the cables are installed on the cable fixing block 5. The first cable clamp 11 and the second cable clamp 51 are both hook-shaped structures, one side of which is fixed in the test device by screws, and the other side has a certain elasticity to facilitate the compression of the cables. The cable clamp is mainly used to facilitate the wiring of the cables. Different cables are inserted into different barcode readers or the upper and lower fine-tuning mechanisms 6 and the driving components of the fixed locking mechanism 7 to achieve data communication or driving action.

[0026] The up and down fine-tuning mechanism 6 includes a first plate, a lifting cylinder, and a screw nut mechanism. The rear of the first plate is fixedly connected to the cable fixing block 5, the front of the first plate is equipped with a screw nut mechanism, the top of the first plate is equipped with a lifting cylinder that drives the screw nut mechanism to move up and down, and the moving nut of the screw nut mechanism is fixedly connected to the fixed locking mechanism 7. Driven by the lifting cylinder, the moving nut is driven to move slightly in the screw nut mechanism, thereby fine-tuning the height of the barcode reader clamped in the fixed locking mechanism 7.

[0027] Furthermore, the fixed locking mechanism 7 includes a second plate body, two-way cylinders 71 are installed on both sides of the second plate body, a claw 72 is installed in the middle of the second plate body, and the two-way cylinder 71 is in transmission connection with the claw 72. The two-way cylinder 71 drives the two claws 72 to gather toward the middle to clamp the barcode readers of different widths placed in the middle, thereby adapting to fixed barcode readers of different widths.

[0028] As a preferred solution, foot pads 2 are installed at the four ends of the bottom of the base plate 1. The foot pads 2 are truncated cone-shaped structures and are made of rubber. When implemented, the foot pads 2 are fixed to the base plate 1 with screws to play a role in silent contact. Figure 4 The test main board 8 is provided with a network communication interface, a serial communication interface, a USB interface, and a power interface for connecting a barcode reader or the driving components of the up and down fine-tuning mechanism 6 and the fixed locking mechanism 7.

[0029] In this test device, a first cable clamp 11 and a second cable clamp 51 are designed as cable fixing grooves to lead out and fix the mainboard wiring of the bottom test mainboard 8. This test device can be connected to a PC for testing by selecting different cables, eliminating a series of work such as replacing test equipment, cables, and bases, effectively improving versatility and testability.

[0030] For the fixed barcode reader product test, all external interfaces need to be tested, and the host computer test program is connected through the PC. The remaining external functional interfaces are connected to this test device through test cables. The functional interfaces are selected through buttons, indicator lights, wave switches, etc. and the test results are output on the PC. The results are displayed clearly. On this test device, multiple selection cables are set to select and connect multiple fixed barcode reader devices. Due to the consistency of external interfaces and functional consistency, this test device can use a set of test fixtures to test multiple devices, which significantly improves the test efficiency and consistency of fixed barcode readers in this industry.

[0031] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
