[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0018] The following is in conjunction with the appendix Figures 1 to 2 The present application provides a detailed description of a zero-position calibration fixture 1 for an aircraft stall protection computer through specific embodiments and application scenarios.

[0019] This utility model provides a zero-position calibration fixture 1 for an aircraft stall protection computer, including a fixed panel 10 and a support platform 11 disposed on the fixed panel 10; the fixed panel 10 has a main hole 100 and a plurality of positioning holes 101 are also provided along the circumference of the main hole 100; the support platform 11 includes a first support platform 110 and a second support platform 111, the second support platform 111 is connected to an air knife fixing block 12 by a screw 120, and the air knife fixing block 12 can move in the horizontal direction toward the first support platform 110.

[0020] Understandably, the positioning hole 100 is used to mount the panel of the stall protection computer on the fixed panel 10 for calibrating the main body of the stall protection computer. The position of the main hole 100 is adapted to the position of the panel of the stall protection computer, so that the air knife assembly of the stall protection computer can pass through the main hole 100 and be fixed between the air knife fixing block 12 and the first support platform 110. The air knife assembly can also obtain a relatively stable positioning calibration. At the same time, the air knife fixing block 12 is set to be movable, so air knife assemblies of various sizes can obtain good calibration positioning under the adjustable air knife fixing block 12, improving the adaptability of the zero-position calibration fixture.

[0021] Furthermore, the main hole 100 is provided with at least 8 positioning holes 101 at equal intervals around its circumference.

[0022] Specifically, at least eight positioning holes 101 are provided to accommodate most models of stall protection computers. For example, the 866-0009-010 stall protection computer has two positioning pins, or other models of stall protection computers can be fixed to the fixed panel 10 through the positioning holes 101 for subsequent calibration work.

[0023] Furthermore, the second support platform 111 is connected to the air knife fixing block 12 by at least two screws 120. The second support platform 111 is provided with an adjustment knob 122 corresponding to the screws 120, which can adjust the distance between the air knife fixing block 12 and the first support platform 110.

[0024] Understandably, setting at least two screws 120 can effectively improve the fixing effect of the air knife fixing block 12. By adjusting the distance between the air knife fixing block 12 and the first support platform 110 through the screws 120, the spacing can be adjusted according to the air knife assembly size of different stall protection computers, thereby improving the wide adaptability of the device.

[0025] Furthermore, the first support platform 110 is provided with a boss 1100 facing the second support platform 111, and the position of the boss 1100 corresponds to the air knife fixing block 12.

[0026] Specifically, in order to protect the air knife assembly of the stall protection computer, a small boss 1100 is set separately to contact and fix with the air knife assembly, which can minimize frictional damage to the air knife assembly.

[0027] Furthermore, grooves 1101 are provided on the surfaces of both the boss 1100 and the air knife fixing block 12.

[0028] Understandably, conventional air knife assemblies are similar to air wings, with an arc-shaped structure on their surface. Setting grooves 1101 on the surface of the boss 1100 and the air knife fixing block 12 can better fit the surface shape of the air knife assembly and prevent the air knife assembly from being squeezed and deformed.

[0029] Furthermore, a spring 121 is fitted onto the screw 120.

[0030] Understandably, setting spring 121 can improve the fixing effect of air knife fixing block 12 and improve the subsequent calibration accuracy.

[0031] Further, please refer to Figure 2 The width L of the support platform 11 is 9cm-12cm; preferably 10cm.

[0032] Specifically, a wider support platform 11 is provided to ensure the overall stability of the device during calibration and improve the calibration effect.

[0033] Furthermore, the center of the main hole 100 is located on the central axis of the fixed panel 10.

[0034] Understandably, having the center of the main hole 100 located on the central axis of the device helps improve the overall stability of the stall protection computer when it is fixed in the calibration fixture, and can also improve the stability of subsequent calibration.

[0035] Compared with the prior art, the zero-point calibration fixture provided by this utility model has the following advantages: This utility model provides a zero-position calibration fixture for an aircraft stall protection computer, including a fixed panel and a support platform mounted on the fixed panel. The fixed panel has a main hole and multiple positioning holes circumferentially along the main hole. The support platform includes a first support platform and a second support platform. The second support platform is connected to an air knife fixing block via a screw. The air knife fixing block can move horizontally towards the first support platform. The positioning holes are used to mount the stall protection computer panel on the fixed panel for calibrating the main body of the stall protection computer. The position of the main hole is adapted to the position of the stall protection computer panel, allowing the air knife assembly of the stall protection computer to pass through the main hole and be fixed between the air knife fixing block and the first support platform, thus achieving relatively stable positioning and calibration of the air knife assembly. Simultaneously, the air knife fixing block is movable, so air knife assemblies of various sizes can achieve good calibration and positioning under the adjustable air knife fixing block, improving the adaptability of the zero-position calibration fixture.
