Description

Technical Field

[0001] The utility model relates to the technical field of sonic nozzles, in particular to a fixing device for detecting sonic nozzles. Background Art

[0002] The sonic nozzle is a gradually contracting and expanding channel. When the airflow passes through the contracting section, the speed increases and the pressure decreases, forming a critical airflow at the minimum cross-section. The velocity kinetic energy is then converted into pressure energy through the expanding section, so that the pressure can be restored. After searching, a sonic nozzle calibration device is disclosed in a Chinese patent with the authorization announcement number CN210221214U, which relates to the field of sonic nozzles, including a gas storage tank, a connecting pipe is fixedly connected to one side of the gas storage tank, a sonic nozzle is fixedly installed at one end of the connecting pipe, a bracket is fixedly connected to the lower surface of the sonic nozzle, a support plate is fixedly connected to the bottom of the bracket, a lifting column is fixedly connected to the lower surface of the support plate, piers are fixedly connected to both sides of the gas storage tank, a support platform is arranged below the sonic nozzle, a lead screw is threadedly connected to the middle part of the bottom end of the lifting column, a first bevel gear is fixedly connected to the outer side of the bottom of the lead screw, a bearing seat is movably connected to the bottom end of the lead screw, a second bevel gear is meshedly connected to one side of the first bevel gear, and a rotating shaft is fixedly connected to the middle part of one side of the second bevel gear. The utility model can keep the sonic nozzle stable by arranging the bracket on the sonic nozzle, so that the position of the sonic nozzle is fixed conveniently and the installation of the sonic nozzle is beneficial.

[0003] However, in actual use of this solution, since the bracket is fixedly connected to the top of the support plate, the position of the bracket can only be fixed at a specified position, and the fixing position of the sonic nozzle is also restricted. That is to say, when fixing the sonic nozzle, the device can only be used for a specified gas tank. Once the connecting pipe deviates, the sonic nozzle cannot be detected.

[0004] Therefore, we made improvements on this and proposed a fixing device for sonic nozzle detection. Utility Model Content

[0005] In order to solve the problem that the existing fixing device cannot be adaptively adjusted, the utility model provides a fixing device for sonic nozzle detection.

One side of the fixing frame is threadedly connected to the rotating rod, and the bottom end of the rotating rod passes through the fixing frame and is connected to the top end of the cushion block.

[0017] The beneficial effect of adopting the above further solution is that, by rotating the rotary rod, the bottom end of the rotary rod can press down the cushion block until it contacts the ground surface, thereby playing a supporting role.

[0018] Furthermore, a base frame is welded to the bottom end of the gas storage tank, and the bottom end of the base frame is flush with the bottom end of the bottom plate.

[0035] Embodiment 3

[0036] See also Figure 1-Figure 5 As an embodiment of the present invention, further, the outer wall corners of the bottom plate 600 are respectively provided with support leg assemblies 500, and the support leg assemblies 500 include a fixing frame 5001, a rotating rod 5002 and a cushion block 5003. One side of the fixing frame 5001 is threadedly connected to the rotating rod 5002, and the bottom end of the rotating rod 5002 passes through the fixing frame 5001 and is connected to the top of the cushion block 5003.

[0037] Specifically, the working principle of the sonic nozzle detection fixture is as follows: when in use, first, move the device to the designated working area, and start the device to perform an operation test. After ensuring normal operation, put it into use. The stepper motor 3004 is started so that its output end drives the lead screw 3003 to rotate, and the lead screw 3003 is used in conjunction with the reverse thread so that the lead screw 3003 can synchronously drive the two sliders 3002 to slide. The two sliders 3002, the first inclined surface and the second inclined surface cooperate with each other so that when the two sliders 3002 are moving away from or close to each other, the fixed platform 400 can be prompted to perform a lifting movement until the support block 4003 is adjusted to a designated height. The support block 4003 is then moved. 003 slides inside the slide groove 4002 until it moves to the specified position, and then by turning the locking knob 4006, it follows the support block 4003 to move in the hollow groove 4005 and performs the function of rotation and tightening, thereby prompting the support block 4003 to drive the sonic nozzle 200 to be fixed at the specified position and adapt to the required detection position, and the provision of the anti-slip layer 4004 is helpful to prevent the sonic nozzle 200 from slipping on the top of the support block 4003. Secondly, the ball 6002 rotates inside the spherical groove, so that the bottom end of the plate body 6001 can drive the support seat 300 to move, and by rotating the rotary rod 5002, the bottom end of the rotary rod 5002 can press down the pad 5003 until it contacts the ground surface, thereby playing a supporting role.

[0038] It should be noted that the specific model and specifications of the stepper motor 3004 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0039] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model.
