Description

Technical Field

[0001] This utility model belongs to the technical field of positioning devices, and in particular relates to a positioning device for testing vacuum cleaner nozzles. Background Technology

[0002] Vacuum cleaner nozzle testing is a crucial step in evaluating vacuum cleaner performance and user experience. By testing the design, function, and performance of the nozzles, we can ensure the vacuum cleaner's cleaning effectiveness and ease of use in different scenarios.

[0003] During the testing of vacuum cleaner nozzles, there are many types of vacuum cleaner nozzles on the market, with varying sizes and shapes. This makes it difficult for existing testing devices to position the nozzles. Most existing positioning structures can only accommodate nozzles of specific sizes and cannot effectively position nozzles of other sizes, resulting in poor applicability of the testing devices. This limitation not only reduces testing efficiency but also increases testing costs.

[0004] Meanwhile, the top of the nozzle is usually designed with spray columns, which play an important role in the nozzle's use, such as guiding airflow and enhancing suction. However, these spray columns are often quite fragile, and may be made of soft materials or have a delicate structure. During positioning, if excessive pressure is applied or the positioning method is improper, the spray columns can easily be damaged. Once the spray columns are damaged, it will not only affect the normal performance of the nozzle, but may also lead to inaccurate test results, or even render the nozzle unusable, requiring additional repair or replacement. Utility Model Content

[0005] The purpose of this invention is to provide a positioning device for testing vacuum cleaner nozzles, which addresses the problem that the positioning structure of existing testing devices cannot be applied to nozzles of various specifications. Furthermore, due to the special structure of the nozzles, it is easy to damage the spray column during positioning, thus affecting the normal performance of the nozzles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a positioning device for testing vacuum cleaner nozzles, comprising: a workbench on which a connecting plate is provided, and a positioning seat fixed on the connecting plate by a plurality of adjustable parts; and a positioning mechanism connected to a fixed plate, wherein the positioning mechanism is located directly above the positioning seat.

[0007] As a further description of the above technical solution:

[0008] The positioning seat includes a positioning plate and a positioning boss, the positioning boss is connected to the positioning plate, and the positioning boss is provided with a positioning groove.

[0009] As a further description of the above technical solution:

[0010] The adjustable component includes a stud, a shim nut, and a limiting plate. The stud is connected to the connecting plate, the shim nut is screwed onto the stud, and the limiting plate is connected to the stud and located above the shim nut.

[0011] As a further description of the above technical solution:

[0012] The connecting plate is provided with a number of fixing holes, and the limiting plate is provided with an oblong hole. The fixing member passes through the oblong hole and the connecting plate in sequence and is fixed in the fixing hole.

[0013] As a further description of the above technical solution:

[0014] Several of the adjustable components are arranged diagonally.

[0015] As a further description of the above technical solution:

[0016] The fixed plate is connected to the support column, the support column is connected to the connecting seat, the positioning mechanism includes a telescopic cylinder and a positioning body, the telescopic cylinder is connected to the fixed plate, the positioning body is connected to the telescopic cylinder, the positioning body is provided with a plurality of receiving grooves, and the bottom of the receiving groove is provided with a positioning hole.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, a connecting plate is set on the workbench, and the connecting plate is provided with several fixing holes. The positioning seat is fixed on the connecting plate by adjustable parts arranged diagonally. The adjustable parts are fixed in the fixing holes by the fixing parts passing through the waist-shaped holes, thereby fixing the positioning seat and positioning the nozzle. When facing nozzles of different specifications, only different positioning seats need to be replaced, which has strong applicability.

[0019] 2. In this utility model, by setting a positioning hole in the receiving groove, the positioning hole extends through to the positioning body. When positioning the top of the nozzle, the spray column is directly located in the positioning hole, and the positioning body abuts against other parts of the top of the nozzle, thereby achieving all-round positioning of the nozzle. This avoids damage to the nozzle due to the special shape of the spray column. Furthermore, when testing the nozzle, the connecting tube can be placed in the receiving groove and directly inserted into the spray column, avoiding the difficulty of connecting the test tube to the spray column when using traditional positioning devices.
