Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0022] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0023] In addition, the ...

Abstract

The invention discloses a fan rotation speed measuring fixture. The fan rotation speed measuring fixture comprises a power supplyinput connector and a plugging connection base, wherein the plugging connection base is provided with multiple plugging connection places for plugging fan power lines; multiple branches are connected in parallel between the power supplyinput connector and the multiple plugging connection places; and each branch is provided with a switch. According to the fan rotation speed measuring fixture, power supplies of fans are separately connected with the power supplyinput connector through the plugging connection base and the switches; the turning-on and turning-off of the corresponding fan power lines are realized through the switching-on and switching-off of the switches, so that repeated disassembly of the fan power lines during a measuring wind grade adjustment process is avoided, and the efficiency of measuring wind grade adjustment is favorably improved; meanwhile, the phenomenon that connection lines are tangled because too many unit wind grades exist is avoided; and safety hazards such as product burning and working personnel electric shock caused by line connection error is prevented, so that the reliability and safety during the measuring process are favorably improved.

Description

technical field [0001] The invention relates to a tool for testing the rotational speed of a fan. Background technique [0002] When testing the noise and air volume of the air conditioning unit in the laboratory, for the unit without remote control and wire controller, it is necessary to repeatedly disconnect and disconnect the wiring of the unit to adjust the test windshield. Due to the large number of windshields of the unit, the wiring is easily confused, resulting in low efficiency of the test process, which is not conducive to the efficient adjustment of the test windshield of the fan unit by the experimenter. Contents of the invention [0003] The main purpose of the present invention is to provide a fan speed test tool, aiming at improving the efficiency of adjusting the test windshield of the fan. [0004] In order to achieve the above object, the fan speed test tool proposed by the present invention includes a power input interface and a socket, and the socket h...
